An apparatus for distributing gases and, optionally, liquids into a control valve includes a collar and a plurality of gas distribution devices. The collar includes a first side, a second side opposite the first side, an inner bore formed through a central portion of the first side and the second side, an outer edge positioned between the first side and the second side and which defines an outer perimeter of the collar, an inner edge positioned between the first side and the second side and which extends around the inner bore to define an inside perimeter of the collar, and a plurality of passages that extend through the outer edge and inner edge without penetrating the first and second sides. The plurality of gas distribution devices are mounted into the passages of the collar.

A distributor head of a distribution agricultural device comprises an outer hoop provided with at least four outlets of the same size, arranged evenly along the circumference of the outer hoop, a movably positioned ring, a main inlet, and a driving mechanism connected with the ring through a ring attachment, wherein the ring is provided with a number of evenly arranged openings of the same size, number of which corresponds to half of the number of outlets. The ring can be in three operating positions, wherein in the first position, the ring is located in the same plane as the outer hoop and therefore covers every other outlet, in the second position it is not located in the same plane as the outer hoop and thus does not cover any outlet, and in the third position it is located in the same plane as the outer hoop and thus covers every other outlet, wherein the outlets covered in the third position are different from the outlets covered in the first position of the ring.

A vacuum conveying system has at least two storage locations and at least two consumers connected by supply conduits and discharge conduits to each other. A vacuum source is provided that produces a vacuum flow/air flow. A central material conduit is provided with valves, wherein the supply conduits and the discharge conduits each have one of the valves associated therewith. The valves actuate conveying paths of bulk material from the at least two storage locations to the at least two consumers. The valves have a first position and a second position, wherein in the first position the valves open the material conduit to provide a through passage. In the second position, the valves supply the vacuum flow/air flow to the central material conduit or conduct the vacuum flow/air flow away from the central material conduit.

A mechanically-controlled vacuum throttle for a continuous dense phase pneumatic conveying system and related method is provided. The system includes a pneumatic conveyance line, a particulate material insertion assembly, a positive displacement blower, a transport fluid intake assembly, and a vacuum throttling assembly. The vacuum throttling assembly is configured to control the flow of air mass density into the blower and through the conveyance line. A portion of the vacuum throttling assembly is tied in to the conveyance line pressure downstream of the blower and adjusts the air mass density flow depending on the downstream pressure. Preferably, the vacuum throttling assembly includes an obstruction element and an opening collar, where the obstruction element is moveable relative to the opening collar and the air mass density flow is adjusted depending on the amount of movement of the obstruction element relative to the opening collar.

The present invention is directed to an applicator having an agricultural product mechanical and/or pneumatic conveying system which transfers particulate material from one or more source containers to application equipment on demand, and meters the material at the application equipment. The conveying system includes a static distributor interconnecting the supply lines of the conveying system with the distribution lines connected to the individual nozzles. The static distributor includes internal structures that effectively divert the incoming particulate material evenly across the interior of the static distributor such that the particulate material is evenly distributed into each of the distribution lines. The static distributor accomplishes this without the need for any moving parts or control systems/devices. In addition, damage done to the particulate material flowing through the distributor is not high, and the operation of the distributor creates a lower pressure drop across the distributor than prior art vertical distributors.

A flow splitter for distributing agricultural products includes a splitter body extending between upstream and downstream ends and defining an inlet port and two or more outlet ports. The splitter body includes an inner flow surface defining an interior flow volume and two or more internal grooves extending radially outwardly from the inner flow surface. A divider of the flow splitter extends within the splitter body along a central axis and includes two or more divider walls extending radially outwardly from the central axis to a distal end positioned adjacent to the inner flow surface. The divider divides at least a portion of the interior flow volume into a plurality of internal flow chambers, each being aligned with a respective outlet port. A rib extends radially outwardly from the distal end of each respective divider wall such that each rib is received within a respective internal groove.

An object of the present invention is to provide a technique in which deposition of powder during pneumatic transport can be inhibited by a pipe body having a simple structure. The present invention is a pipe for transporting powder including a transport path which has a portion formed by a curved pipe and through which pneumatically transported powder passes, and a blowing path through which a gas is blown into the transport path from an opening formed on an inner circumferential surface of the curved pipe, in which the blowing path blows the gas in a direction in which the gas blown into the transport path from the opening forms a swirling flow along the inner circumferential surface of the curved pipe.

A system for conveying pasty material through a conduit has an eccentric screw pump having a stator, a rotor that rotates in the stator, a housing with an intake port, and an output port connected to the conduit. A drive rotates the rotor and thereby draws the pasty material in through the intake port and expels the drawn-in material as a compressed-material strand into the conduit. A valve supplies gas pulses to the conduit at time intervals for separating the compressed-material strand into material plugs of limited length traveling through the conduit.

Process and device for pneumatically conveying a powdery material comprising the steps of Pneumatically conveying a powdery material in a pneumatic conveying pipeline (first) and into said recipient by a flow generated by a blower, A powdery material dosing step, A fluctuation step of pressure drop in said pneumatic conveying pipeline or up to said recipient,
wherein a sonic device generates sonic waves inside said pneumatic conveying pipeline or up to said recipient and provides a counteraction on the fluctuation step of the pressure drop in said pneumatic conveying pipeline or up to said recipient.
