The invention provides a powder conveying device including: a pump body (1), a powder sucking plunger (4), a powder suction conduit (2), a powder discharge conduit (3), a powder suction valve (5), and a powder discharge valve (6), wherein the pump body (1) comprising a transfer chamber (13) that is configured with a powder inlet (11) connected to the powder suction conduit (2) and a powder outlet (12) connected the powder discharge conduit (3); and a powder sucking plunger (4) configured in the upper part of the transfer chamber (13) and movable up and down inside the transfer chamber (13). When the powder sucking plunger (4) moves upward, the powder suction conduit (2) is opened by the powder suction valve (5) and the powder discharge conduit (3) is closed by the powder discharge valve (6) so that the powder is sucked into the transfer chamber (13) through the powder suction conduit (2). When the powder sucking plunger (4) moves downward, the powder suction conduit (2) is closed by the powder suction valve (5) and the powder discharge conduit (3) is opened by the powder discharge valve (6) so that the powder is discharged from the transfer chamber (13) through the powder discharge conduit (3). The powder inlet (11) is configured in the inner sidewall (130) of the transfer chamber (13), and the powder inlet (11) is above the powder outlet (12). Therefore the powder outflow is much smoother. Further, the quantity and stability of the powder feeding is improved.

A system for replenishing the supply of a particulate agricultural product in the tank of an air cart. A mixture of air and product comes out of a venturi delivery system and enters in a multiplicity of inlet hoses. Then the product enters into inlet tubes of various lengths and release angles from which product particles are gently spread strategically forming a pile that is more or less horizontal to ensure even feeding of meters during dispensing operations. Then the air exits through one or more fine screens to avoid product escaping as well and is conveyed through the exhaust hoses until reaching an air diffuser. The air diffuser has a series of varying size holes or louvers at the bottom so the air can come out at a uniform low velocity which minimizes any discomfort to nearby operators.

The invention relates to a powder supply device for a powder coating system having at least one powder container (24), which has a powder chamber (22), and having at least one powder dispensing device, which is connected or can be connected to a powder dispensing channel (13) opening into the powder chamber (22) via a powder dispensing opening (36), in order to extract coating powder from the powder chamber (22) during powder coating operation of the powder coating system. In order to achieve as homogeneous and effective a powder conveyance as possible using the powder supply device according to the invention, the at least one powder dispensing device is designed as a powder dense flux pump (4), in particular as a single-chamber powder dense flux pump (200).

This powder transport device comprises: transport pipe (11) that can transport powder by way of gravity by having a prescribed angle of inclination; a porous plate (12) that is disposed along the transport pipe (11) so as to divide a line cross section into a top section and bottom section and form a powder line (11d) in the top section; an inert gas supply line for fluidization (13) that is provided under the porous plate (12) and supplies an assist gas (g) to the powder line (11d) through the porous plate (12); and a deposit status monitoring device (20) that constantly monitors the state of the powder deposited on the top face side of the porous plate (12) in the powder line (11d).

A conveying system for conveying a conveyable material from a hopper where the system includes a fluid port located below the hopper outlet and in a vertical flow path into hopper outlet that can be momentarily opened for an on the go release of a charge of compressed air directly upward into the hopper outlet and into the underside of the bridge in the hopper to either disintegrate or unlock the bridged particles from each other thereby causing the bridged material to fall into the hopper outlet and into the conveying system where the material can be transported to a remote location or to remove any material that may be adhering to the wall during an emptying phase.
