The first and second closed ring-piece assemblies are stacked alternately to form the filter chamber 1. In the first and second closed ring-piece assemblies, a gasket 6 is disposed between two adjacent closed ring-pieces of a plurality of closed ring-pieces of one of the closed ring-piece assemblies, and a thickness of the gasket 6 is greater than that of any one of the closed ring-pieces of another one of the closed ring-piece assemblies, so that a filter gap is formed between the two adjacent closed ring-pieces.

[0046] Specifically, referring to FIG. 1 to FIG. 5 again, the first closed movable ring-piece assembly 4 is connected into a whole through a first connection mechanism 7 that passes through the plurality of closed ring-pieces of the first closed movable ring-piece assembly 4. The driving device 3 drives the plurality of closed ring-pieces of the first closed movable ring-piece assembly 4 through a first gearing device 8 to reciprocate the same circular track in all directions, so that a relative displacement occurs between the first closed movable ring-piece assembly 4, the support frame 9 and the adjacent second closed ring-piece assembly. Accordingly, the filter gap becomes more unobstructed and a filter area of the filter gap is increased.

[0047] Further, referring to FIG. 1 to FIG. 5 again, the first connection mechanism 7 includes at least two first linkage shafts 11. Each of the first linkage shafts 11 passes through a support frame escaping hole 10 and a first closed movable ring-piece through hole 40 of the first closed movable ring-piece assembly 4. The first linkage shafts 11 are configured to connect the first closed movable ring-piece assembly 4 into a whole and realize synchronous movement. In the present embodiment, a quantity of the first linkage shafts 11 is two. In another embodiment, a quantity of the first linkage shafts 11 is three, four, five or more.

[0048] Referring to FIG. 1 to FIG. 5 again, the first gearing device 8 includes at least two first gearing shafts 12, a first linkage ring-piece 13 and a first eccentric mechanism 14. Each of the first gearing shafts 12 passes through a support frame through hole 51 to be assembled with the driving device 3, and can move synchronously with the driving device 3. The first linkage ring piece 13 is sleeved on the at least two first gearing shafts 12 simultaneously. The first linkage ring-piece 13 is fixedly assembled with the first linkage shafts 11 and is disposed in balanced between two adjacent closed ring-pieces of the first closed movable ring-piece assembly 4. The first eccentric mechanism 14 is disposed between the first linkage ring-piece 13 and the first gearing shaft 12. The first eccentric mechanism 14 is configured to drive all the movable ring-pieces of the first closed movable ring-piece assembly 4 to generate a reciprocating motion of a same circular track.

[0049] Preferably, the first linkage ring-piece 13 has a first linkage ring-piece through hole 41. The first linkage shaft 11 passes through the first closed movable ring-piece through hole 40 and the first linkage ring-piece through hole 41.

[0050] Specifically, referring to FIG. 1 to FIG. 5 again, the first eccentric mechanism 14 includes a first eccentric wheel 15 and a first limit piece 16. The first eccentric wheel 15 is fixedly mounted on the first gearing shaft 12 and is located in the first linkage ring-piece mounting hole 42. The first eccentric wheel 15 is in contact with an inner wall of the first linkage ring-piece mounting hole 42 through a first bearing 47. When the first gearing shaft 12 rotates, the first eccentric wheel 15 drives the first linkage ring-piece 13 to generate a reciprocating motion of the same circular track. The first limit piece 16 is fastened to a first mounting ear 49 of the first linkage ring-piece 13 and is located on both sides of the first linkage ring-piece mounting hole 42. The first limit piece 16 is configured to limit the first eccentric wheel 15 in the first linkage ring-piece mounting hole 42.

[0051] In the present embodiment, the second closed ring-piece assembly is a closed fixed ring-piece assembly 17 in a static state of motion. Each of fixed ring-pieces of the closed fixed ring-piece assembly 17 has two or more fixing holes 18. Two or more fixed shafts 46 respectively pass through the two or more fixing holes 18. The fixed shafts 46 are used for fixing the closed fixed ring-piece assembly 17 on the support frame 9.

[0052] In another embodiment, referring to FIG. 5 to FIG. 13, the second closed ring-piece assembly is a second closed movable ring-piece assembly 5. The second closed movable ring-piece assembly 5 is connected into a whole by a second connection mechanism 19 that passes through the closed ring-pieces of the second closed movable ring-piece assembly 5. The driving device 3 drives the closed movable ring-pieces of the second closed movable ring-piece assembly 5 through a second gearing device 20 to perform a reciprocating motion of the same circular track in all directions, so that a relative displacement occurs between the second closed movable ring-piece assembly 5, the support frame 9 and the adjacent first closed movable ring-piece assembly 4. Accordingly, the filter gap becomes more unobstructed and a filter area of the filter gap is increased.

[0053] Referring to FIG. 5 to FIG. 13 again, the second connection mechanism 19 includes at least two second linkage shafts 22. Each of the second linkage shafts 22 passes through a support frame escaping hole 10 and a second closed movable ring-piece through hole 43 of the second closed movable ring-piece assembly 5. The at least two second linkage shafts 22 are configured to connect the second closed movable ring-piece assembly 5 into a whole and realize a synchronous movement.

[0054] Specifically, as shown in FIG. 5 to FIG. 13 again, the second gearing device 20 includes at least two second gearing shafts 23, a second linkage ring-piece 24, and a second eccentric mechanism 25.

[0055] The second gearing shafts 23 are assembled with the driving device 3 through the support frame through hole 51 and can move synchronously with the driving device 3. The second linkage ring-piece 24 is sleeved on the second gearing shafts 23. The second linkage ring-piece 24 is fixedly assembled with the second linkage shaft 22 and is disposed in balanced between two adjacent second closed movable ring-pieces of the second closed movable ring-piece assembly 5. The second eccentric mechanism 25 is disposed between the second linkage ring-piece 24 and the second gearing shaft 23. The second eccentric mechanism 25 is configured to drive all the movable ring-pieces of the second closed movable ring-piece assembly 5 to generate a reciprocating motion of the same circular track.

[0056] Preferably, the second gearing shaft 23 can be shared with the first gearing shaft 12. The second linkage ring-piece 24 has a second linkage ring-piece through hole 44. The second linkage shaft 22 passes through the second closed movable ring-piece through hole 43 and the second linkage ring-piece through hole 44.

[0057] As shown in FIG. 5 to FIG. 13 again, the second eccentric mechanism 25 includes: a second eccentric wheel 26 and a second limit piece 27. The second eccentric wheel 26 is fixedly mounted on the second gearing shaft 23 and is located in the second linkage ring-piece mounting hole 45. The second eccentric wheel 26 is in contact with an inner wall of the second linkage ring-piece mounting hole 45 through a second bearing 48. When the second gearing shaft 23 rotates, the second eccentric wheel 26 drives the second linkage ring-piece 24 to generate a reciprocating motion on the same circular track. The second limit piece 27 is fastened to a second mounting ear 50 of the second linkage ring-piece 24 and is located on both sides of the second linkage ring-piece mounting hole 45. The second limit piece 27 is configured to limit the second eccentric wheel 26 in the second linkage ring-piece mounting hole 45.

[0058] It should be noted that the solid-liquid separator of the present embodiment also includes the first eccentric mechanism 14, and an eccentric direction of the first eccentric wheel 15 and an eccentric direction of the second eccentric wheel 26 have an included angle there-between. Alternatively, the included angle between the eccentric directions of the first eccentric wheel 15 and the second eccentric wheel 26 is 0 degrees, but the eccentric distances of the first eccentric wheel 15 and the second eccentric wheel 26 are inconsistent.

[0059] As shown in FIG. 1 and FIG. 3, the driving device 3 includes: a first power source 28, a first gear assembly 29 and a gear box 30. The gear box 30 is disposed on the support frame 9 and is located on one side of the discharge channel 102. The first gear assembly 29 is disposed in the gear box 30. Driven by the first power source 28, the first gear assembly 29 drives the first gearing shaft 12 and the first linkage shaft 11 to move through the meshing transmission between the gears, thereby driving the first eccentric mechanism 14 to move. Preferably, the first gear assembly 29 has six gears that mesh with each other, so that the rotation speeds of the spiral shafts 2 in the filter chamber 1 are consistent and the rotation directions of the spiral shafts 2 are opposite to each other. The rotation speed of the first gearing shaft 12 drives the movement of the first closed movable ring-piece assembly 4 to be consistent with the direction of rotation.

[0060] In another embodiment, as shown in FIG. 14, the driving device 3 includes a gear box 30, a second gear assembly 32, a third gear assembly 33, a second power source 34 and a third power source 35.

[0061] The gear box 30 is disposed on the support frame 9 and is located on one side of the discharge channel 102. The second gear assembly 32 is disposed in the gear box 30. The second gear assembly 32 is used for driving the spiral shafts 2 to generate movements with the same rotational speeds and opposite rotational directions. The third gear assembly 33 is disposed in the gear box 30. The third gear assembly 33 is configured to drive the first gearing device 8 to rotate, so that the first closed movable ring-piece assembly 4 produces the movements with the same rotational speeds and rotational directions. The second power source 34 is disposed on a side of the gear box 30 away from the filter chamber 1 and extends into the gear box 30 to be assembled with the second gear assembly 32. The second power source 34 is configured to drive the second gear assembly 32 to move. The third power source 35 is disposed on the side of the support frame 9 away from the filter chamber 1 and extends into the gear box 30 to be assembled with the third gear assembly 33. The third power source 35 is configured to drive the third gear assembly 33 to move.

[0062] Alternatively, the driving device 3 is arranged on the side of the discharge channel 102 and the side of the feed port 101 at the same time, and outputs the same rotational speed and steering power to the gearing shaft to reduce the driving load when the equipment is enlarged.

[0063] It should be noted that the working flow of the solid-liquid separator is as follows. Flocculated material enters the filter chamber through the feed port of the reciprocating lamination spiral solid-liquid separator. The material is continuously pushed forward by the two spiral shafts in the filter chamber with opposite directions. Even if the material is easy to entangle and harden, the material will move forward smoothly because of the mutual scraping between the two spiral shafts. In the process of material being conveyed, the filter chamber is displaced with the adjacent closed ring due to the reciprocating motion of the closed movable ring-pieces, so that the filter seam is kept unobstructed. The filtrate can be discharged from the inside of the filter chamber through the filter slit and collected into the filtrate collection tank in the conventional art. The dehydrated material is finally discharged from the discharge channel

[0064] [Second Embodiment] The second embodiment is based on the first embodiment. The second embodiment provides a mixing tank with pre-concentration function. The mixing tank is equipped with a stirring device with the pre-concentration function. The stirring device with the pre-concentration function includes: a driving device 3, the above-mentioned filter chamber 1, a stirring blade, and a filtrate guiding chamber 36. The driving device includes a driving motor 37, a central axis 38 and a gear assembly 39 assembled with the central axis 38. The filtrate guiding chamber 36 is located at the bottom of the filter chamber 1. The filtrate guiding chamber 36 communicates with the interior of the filter chamber 1. The central axis 38 passes through the inside of the filter chamber 1 and the filtrate guiding chamber 36.

[0065] It should be noted that the workflow of the mixing tank with the pre-concentration function is as follows. In the mixing tank with the pre-concentration, the flocculated material is arranged in the filter chamber above the mixing tank. Due to the reciprocating motion of the closed movable ring-pieces, the filter chamber is displaced with the adjacent closed ring-pieces to keep the filter seam unobstructed. The filtrate can be discharged inward from the outside of the filter chamber through the filter slit, and can be discharged through the filtrate guiding chamber communicated with the filter chamber. The concentration of the material left in the mixing tank becomes higher, so as to achieve the effect of pre-concentration.

[0066] The above is only used to illustrate the technical solution of the present disclosure and not to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present disclosure, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be included in the within the scope of the claims of the present disclosure.
