A blow-through rotary valve is provided which has a modified geometry to reduce wear from pneumatic conveying of particulate and/or bulk material.

A modular hopper tee including a modified tee box, a tee box liner, a readily detachable inflow adapter for coupling a first pipe to the tee box and a readily detachable outflow adapter for coupling a second pipe to the tee box, the liner and adapters being constructed from an elastomeric polymer such as polyurethane. Each of the inflow and outflow adapters includes a flange portion and a cylinder portion extending through the flange portion, the flange portion dividing the cylinder portion into a first cylinder portion that extends through a sidewall opening of the tee box and sealingly engages the liner and a second cylinder portion that is located outside of the box. A metal cylinder member, which is embedded within the first cylinder portion and surrounds an exterior of the second cylinder portion, is provided for reinforcing the adapter.

The present disclosure discloses a pneumatic conveying system and an optimized configuration method. The pneumatic conveying system uses a pressure-type elephant bionic trunk conveying pipeline to convey a material or uses a suction-type elephant bionic trunk conveying pipeline to convey a material, wherein the pressure-type elephant bionic trunk conveying pipeline is a pipeline with a gradually enlarged inner diameter, and the suction-type elephant bionic trunk conveying pipeline is a pipeline with a gradually reduced inner diameter.

The invention relates to a method for transporting foamed thermoplastic polymer particles (3) from a container (5, 9) through at least one pipe (7, 11), wherein, for transporting the foamed thermoplastic polymer particles (3), a gas stream is applied through the pipe (7, 11). The foamed thermoplastic polymer particles (3) are wetted with a water comprising lubricant.

A system includes a product delivery tube having an air inlet, an agricultural product inlet, and an exit nozzle. The agricultural product inlet is disposed between the air inlet and the exit nozzle, and the first product delivery tube is configured to receive the agricultural product from the agricultural product inlet, and to use an air flow received by the air inlet to convey the agricultural product through the exit nozzle. The system also includes a drop tube configured to receive the agricultural product, and to convey the agricultural product at a drop tube angle to the agricultural product inlet. The drop tube angle is formed by a junction between the first drop tube and the first product delivery tube, and the drop tube angle is greater than approximately 0 degrees and less than approximately 90 degrees relative to the product delivery tube.

The invention relates to improvements in the technical field of feeding solid materials to mixing devices. For this purpose, the solid-material feeding device, inter alia, is proposed. The solid-material feeding device comprises the slide, which can be moved between a first end position and a second end position through a conveying connection, which is arranged between a funnel and a solid-material outlet of the solid-material feeding device. By means of the slide, adhesions within the conveying connection can be loosened without having to remove the conveying connection.

A pneumatic conveying system and a control method therefor. The system comprises a power unit (1), a fan unit (2), a valve unit (3), a sensor unit (4), a pneumatic conveying unit (5), a pipeline arrangement net (6) and a control system (7), wherein the he fan unit (2), the valve unit (3), the sensor unit (4) and the pneumatic conveying unit (5) are connected together in an ordered manner by means of the pipeline arrangement net (6) to form a whole.

A snow conveying assembly for use with a snow making machine includes an impeller for receiving snow from the snow making machine and accelerating the snow; and an ejector tube, which receives the snow from the impeller, further accelerates the snow and discharges the snow from the assembly. The ejector tube contains a venturi throat. Snow from the impeller is conveyed via a snow inlet tube into the ejector tube immediately upstream of a venturi throat and air under pressure is blown into the ejector tube upstream of the venturi throat to further accelerate the snow.
