DESCRIPTION OF THE PREFERRED EMBODIMENT
[0087] The embodiments of the present invention will be described hereinbelow in conjunction with the above-described drawings. Referring to the attached drawings as follows, a concrete execution of the manufacturing process of a large-scale high-pressure gasholder in which a plurality of internal tanks have been accumulated in honeycomb structure is explained.
[0088]
[0089] Each Internal Tank (1) is manufactured from plastic cylindrical tank reinforced by thermosetting carbon fiber prepreg. The Internal Tank (1) has two connection ports in it. A plurality of Internal Tanks (1) are connected in series by these connection ports. Internal Connection Pipes (2) continuously connect the Internal Tanks (1). The Internal Connection Pipes (2) are made of stainless steel.
[0090] External Piping System (3) is composed of Shut Off Valve (4), (5a) Air Compressor, (5b) Accumulator, Electric Heater (6), Flow Control Valve (7), Discharge Tank (8), Thermometer (9) and Pressure Gauge (10). Two Shut Off Valves (4) have adhered to the entrance and the exit of the External Piping System (3).
[0091] External Piping System (3) is pressurized and heated by Air Compressor (5a) and Electric Heater (6), Accumulator (5b) controls the pressure fluctuation of compress air. Air Compressor (5a) pressurizes a line of Internal Tanks (1) connected with the External Piping System (3), However, Electric Heater (6) cannot heat a plurality of Internal Tanks (1) at the same time because the Electric Heater (6) is only partially heating compressed air in External Piping System (3). It is necessary to make the compressed air heated by Electric Heater (6) circulate to heat Internal Tank (1).
[0092] Flow Control Valve (7) is attached to the External Piping System (3). The External Piping System (3) ends at Flow Control Valve (7); thus the compressed air of the External Piping System (3) is discharged into Discharge Tank (8). The Discharge Tank (8) is at atmospheric pressure. Compressed air discharged into the Discharge Tank (8) is decompressed to atmospheric pressure, and inputted from the entrance of the Air Compressor (5a). Thus, the compressed air heated by the Electric Heater (6) circulates in a line of Internal Tanks (1) and through the External Piping System (3).
[0093] Thermometer (9) and Pressure Gauge (10) are mounted along External Piping System (3) to measure temperature and pressure, Heating Oven (11) heats the entire container from the outside of the container. The inside of Heating Oven (11) is at one atmospheric pressure. The system for heating and pressurizing Internal Tanks (1) is placed in Heating Oven (11). When a heatproof performance of Air Compressor (5a) is insufficient, Air Compressor (5a) may be implemented outside of the oven.
[0094] A line of Internal Tanks (1) are pressurized statically when Air Flow Control Valve (7) is not open. It is easy to pressurize the inside of Internal Tanks (1) to about 20 atmospheric pressures with Air Compressor (5a). When Air Flow Control Valve (7) is opened, compressed air bleeds from Air Flow Control Valve (7). However, when the flowing quantity of Air Compressor (5a) is large enough, the inside pressure of the Internal Tanks (1) can be kept about 20 atmospheric pressures, because Air Flow Control Valve (7) controls the amount of the bleed air.
[0095] After heat treatment process, Shut Off Valves (4) are closed. The thermosetting carbon fiber prepreg layers melt at about 130° C., and are merged mutually at that temperature. However, it is impossible that FRP made from the thermosetting carbon fiber prepreg obtains structural strength when FRP structure is not cooled enough. Therefore, internal pressure of the Internal Tanks (1) cannot be lowered until the Internal Tanks (1) get cold enough. When the Shut Off Valves (4) are shut, the container tank can be taken out from Heating Oven (11) with the internal pressure of the Internal Tanks (1) maintained. The Manufacturing operation effect improves because the container tank may be cooled outside of the Heating Oven (11).

[0101] It is difficult to maintain the height position of Connection Port (30) constant because Internal Tank (31) slips down by gravity if there is no support. Height Adaptor (32) is used as bottom support of Internal Tank (31). Height Adaptor (32) maintains the height position of Connection Port (30), accurately. Additionally, Height Adaptor (32) is used also for a fitting when Internal Tank (31) is hung down by crane while work process.

[0109] It is difficult to maintain the height position of Connection Ports (42) constant because Internal Tank (43) slips down by gravity if there is no support. Height Adaptor (44) is used as the bottom support of Internal Tank (43). Height Adaptor (44) maintains the height position of Connection Port (43), accurately. Additionally, Height Adaptor (44) is used also for a fitting when Internal Tank (31) is hung down by crane while work process.

[0117] Internal Tank (55) is heated and pressurized by the compressed air at high temperature from the inside. The entire Honeycomb Set Tank (59) is heated from outside in a large-scale heat oven. The heat foam resin included in Pentagon Cell Tanks (56), Hexagon Cell Tanks (57) and Trapezoid Fillers (58) foams and expands when heated to a high temperature.
[0118] When the outside wall of Honeycomb Set Tank (59) is restrained with an external frame, the pluralities of Pentagon Cell Tanks (56), Hexagon Cell Tanks (57) and Trapezoid Fillers (58) are mutually jostled. The thermoplastic carbon fiber or glass fiber prepreg shells are attached on the surfaces of Pentagon Cell Tanks (56), Hexagon Cell Tanks (57) and Trapezoid Fillers (58). The thermoplastic carbon fiber or glass fiber prepreg shells are divided into two parts. So, the thermoplastic carbon fiber or glass fiber prepreg shells, which are structural material of the honeycomb structure, can freely expand. The thermoplastic carbon fiber or glass fiber prepreg shell melts when Honeycomb Set Tank (59) is heated to about 130° C. Then, pluralities of Pentagon Cell Tank (56), Hexagon Cell Tank (57) and Trapezoid Filler (58) are merged mutually.
[0119] During heating, Internal Tanks (55) that are stored in Pentagon Cell Tanks (56) and Hexagon Cell Tanks (57) are strongly pressurized by the heat foam resin. The surface of Internal Tank (55) is reinforced by accumulated carbon fiber thermosetting prepregs. When the accumulated carbon fiber thermosetting prepregs are heated to about 130° C., carbon fiber prepregs are strongly pressurized with the heat foam resin and internal pressure of Internal Tank (55). Then, the accumulated carbon fiber thermosetting prepregs of Internal Tank (55) are merged mutually.
[0120]

[0122]
[0123] The Manufacturing process for the Container Honeycomb Cell is composed of three steps: [0124] (1) Three container walls, Bottom Wall (67), Rear Wall (68), Left Side Wall (69), are assembled into a triangular configuration. [0125] (2) Rear Cushion Wall (70) and Left Side Cushion Wall (71) are squarely assembled on Bottom Wall (67) [0126] (3) A plurality of Pentagon Honeycomb Cells (72), Hexagon Honeycomb Cells (73) and Trapezoid Fillers (74) are set up for shaping the honeycomb structure. A plurality of Pentagon Honeycomb Cells (72), Hexagon Honeycomb Cells (73) and Trapezoid Fillers (74) are assembled together with the outer shell.
[0127] Pentagon Honeycomb Cells (72) are placed surrounding the outer portions of the Container Honeycomb Cell. Hexagon Honeycomb Cells (73) are placed at the central part. Trapezoid Fillers (74) are filled in to correct the irregularities and voids which result along the outer surrounding periphery of the honeycomb structure. The outer shells of Pentagon Honeycomb Cells (72), Hexagon Honeycomb Cells (73) and Trapezoid Fillers (74) are manufactured from thermoplastic carbon fiber or glass fiber prepreg. Thermoplastic carbon fiber or glass fiber prepreg is not cohesive at the room temperature, so the assembly operation of the honeycomb structure is not difficult.
[0128]
[0129] Container Honeycomb Cells (87) are composed of Bottom Wall (75), Rear Wall (76), Front Wall (77), Left Side Wall (78), Right Side Wall (79), Rear Cushion Wall (80), Front Cushion Wall (81), Left Side Cushion Wall (82), Right Side Cushion Wall (83), Pentagon Honeycomb Cells (84), Hexagon Honeycomb Cells (85) and Trapezoid Fillers (86). Bottom Wall (75), Rear Wall (76), Front Wall (77), Left Side Wall (78) and Right Side Wall (79) are manufactured from steel. Rear Cushion Wall (80), Front Cushion Wall (81), Left Side Cushion Wall (82) and Right Side Cushion Wall (83) are manufactured from heat foam resin. Pentagon Honeycomb Cells (84), Hexagon Honeycomb Cells (85) and Trapezoid Fillers (86) are manufactured from heat foam resin and carbon fiber or glass fiber thermoplastic prepreg. Pentagon Honeycomb Cells (84), Hexagon Honeycomb Cells (85) and Trapezoid Fillers (86) are manufactured from heat foam resin and carbon fiber or glass fiber thermoplastic prepreg. Each Pentagon Honeycomb Cell (84) and Hexagon Honeycomb Cell (85) has a large cavity, wherein an internal tank is stored in each cavity.
[0130]
[0131] Container Honeycomb Cell Tank with Height Adapter (91) is composed of Container Honeycomb Cell (88), internal Tank (89) and Height Adapter (90). Container Honeycomb Cell (88) is the same as Container Honeycomb Cell (87) in
[0132] Container Honeycomb Cell Tank with Height Adapter (91) is assembled by inserting Internal Tank (89), to which Height Adapter (90) is attached, into the cavity of Container Honeycomb Cell (88). Internal Tank (89) is inserted into Container Honeycomb Cell (88) from above by crane. The assembling operation of a Container Honeycomb Cell Tank with Height Adapter (91) is not difficult, because the cavity diameter of each Container Honeycomb Cell (88) is larger than the diameter of Internal Tank (89).
[0133]
[0134] Container Honeycomb Cell Tank Top Piping (98) is composed of Internal Tanks (92), Pentagon Honeycomb Cells (93), Hexagon Honeycomb Cells (94), Height Adapters (95), Shut Off Valves (96) and Top Pipings (97). Pentagon Honeycomb Cells (93) are the same as Pentagon Cell Tanks (40). Hexagon Honeycomb Cells (94) is the same as Hexagon Cell Tank (50). Internal Tank (92) and Height Adapter (95) is the same as Internal Tank (31), Height Adapter (32) in
[0135] Container Honeycomb Cell Tank Top Piping (98) is assembled by attaching Shut Off Valve (96) and connecting Top Piping (97) to Internal Tank (92). Height Adapter (95) at the top of Internal Tank (92) is removed before attaching Shut Off Valve (96) and Top Piping (97).
[0136] It is easy to connect Top Piping (97) to Internal Tank (92), because Top Piping (97) only ties two Internal Tanks (92). Internal Tank (92) can be rotated freely in the cylindrical cavity of Pentagon Honeycomb Cell (93) and Hexagon Honeycomb Cell (94). Additionally, Height Adapter (95) at the bottom uniformly adjusts the height position of the connection ports. Shut Off Valve (96) is attached to Internal Tank (92). Therefore, Top Piping (97) actually connects two Shut Off Valves (96). After the Top Piping is finished, the vacant space above Internal Tank (92) is filled with the granulated powder foam resin, and Top Wall of container is installed. The Top Wall of the container is not shown in
[0137] All Internal Tanks (92) of Container Honeycomb Cell Tank are connected in series. The piping at the bottom is processed with the Container Honeycomb Cell Tank turned 180 degrees and the connections in reverse.
[0138]
[0139]
[0140] Internal Tanks (99) are the same as Internal Tanks (92) in
[0141] Bottom Piping (111) is the piping at the bottom of Internal Tanks (99). The piping of the bottom is processed with the honeycomb container tank turned 180 degrees and in reverse. All Internal Tanks (99) are connected in series. It is a little difficult to attach Shut Off Valve (109) and to connect Bottom Piping (111) to Internal Tank (99). Internal Tank (99) cannot be rotated freely in the cylindrical cavity of Pentagon Honeycomb Cell (100) and Hexagon Honeycomb Cell (101), because the top of Internal Tank (99) is already fixed by Top Piping (110). It is necessary to note it is because the piping of Bottom Piping (111) makes a mistake easily in the connection order. The leakage inspection of piping is necessary. After the piping work has finished, the vacant space above Internal Tank (99) is filled with the granulated powder foam resin, and the container wall is installed.
[0142] All Internal Tanks (99) in Honeycomb Container Tank with Piping (114) are connected into one line as shown in
[0143]
[0144]
[0145] The heat foam resin of the honeycomb cell foams when the honeycomb container tank is heated. Also, the walls of the honeycomb container tank are pushed out outside. The container wall assembly can be destroyed, if there is no Reinforcement Frame Device (121). The heat of the heating oven is never interrupted, because the reinforcement frame is a bone structure.
[0146]
[0147]
[0148] High-Pressure Container Tank (134) is an example of honeycomb structural high-pressure set tank, and is designed so that it is accommodated in an ISO ten-foot container. Container Wall (122) is the most outside protection wall of Internal Tank (128) and is hexahedron made of steel. Container Base Palette (123) is welded under High-Pressure Container Tank (134), and transports High-Pressure Container Tank (134) conveniently. Cushion Wall (127) is manufactured from the heat foam resin and is the second protection of Internal Tanks (128). Pentagon Honeycomb Cells (124), Hexagon Honeycomb Cells (125) and Trapezoid Fillers (126) are manufactured from the heat foam resin. The heat foam resin foams and expands when heated. The outer shells of Pentagon Honeycomb Cells (124), Hexagon Honeycomb Cells (125) and Trapezoid Fillers (126) are made of thermoplastic carbon fiber prepreg or thermoplastic glass fiber prepreg. These outer shells mutually merge by the heat-treatment process, and then the shape of merged shells becomes a honeycomb structure.
[0149] The strong honeycomb cell manufactured from carbon fiber or the glass fiber is the third protection of Internal Tanks (128). The honeycomb structure built with carbon fiber or the glass fiber protects Internal Tanks (128) from external shock loading. The heat form resin, which is formed by a heat-treatment process, is the fourth protection of Internal Tanks (128).
[0150] Internal Tank (128) is made from plastic and is reinforced by thermosetting carbon fiber prepreg. The reinforcement structure of Internal Tank (128) is designed to endure the high pressure in a single tank alone. All Internal Tanks (128) are enclosed in High-Pressure Container Tank (134). They are connected in series, by Internal Tank Piping (130). Two Shut Off Valves (129) are attached at the top and bottom of each Internal Tank (128). Shut Off Valve (129) is used when High-Pressure Container Tank (134) is manufactured. They need heat proofing, because the Shut Off Valves (129) are heated at heat treatment process, Shut Off Valves (129) are permanently enclosed in High-Pressure Container Tank (134). Shut Off Valve (129) is also used when High-Pressure Container Tank (134) is transported. Control Board (133) controls the opening and shutting of Shut Off Valve (129). Shut Off Valve (129) can minimize a potential disaster due to Internal Tank (128) being damaged accidentally while transporting High-Pressure Container Tank (134). There are Entrance Connection (131) and Exit Connection (132) in High-Pressure Container Tank (134). Entrance Connection (131) and Exit Connection (132) are the connecting ports to the outside.
[0151] It will be appreciated that modifications may be made in the present invention. This invention is the one invented to improve U.S. Pat. No. 8,917,809 B2. Manufacturing the large-scale container set tank is difficult by U.S. Pat. No. 8,917,809 B2, because the patent heats the honeycomb cell from the outside. The method of the new invention can be applied to the pillar of a large-scale honeycomb structure. In addition, it is difficult to make a honeycomb cell with high size accuracy by the patent of “U.S. Pat. No. 8,917,809 B2”, because the patent manufactures the honeycomb cell with thermosetting prepreg. The method of the new invention can be applied to the rapid-transit railway and the aircraft.
[0152] The spirit of this invention is a technical advancement of U.S. Pat. No. 8,917,809 B2 with new manufacturing facilities. For that purpose, this invention developed the manufacturing process for the honeycomb cell with advanced accuracy and on a large scale. Although the present invention has been fully described in connection with the preferred embodiment thereof with reference to the accompanying drawings, it is to be noted that various changes and modifications will be apparent to those skilled in the art. Such changes and modifications are to be understood as included within the scope of the present invention as defined by the appended claims, unless they depart therefrom.
