DOUBLE PISTON TYPE PNEUMATIC CONVEYOR

WIPO Patent Application WO/2021/179646

A1

A double piston type pneumatic conveyor, comprising a rack (1), a rotor mechanism (2), an upper cylinder mechanism (4), a lower cylinder mechanism (3), a piston drive mechanism (6), and a hydraulic mechanism (7). The hydraulic mechanism (7) is arranged on the rear side of a bottom frame; the rotor mechanism (2) is fixed on the front side of the bottom frame; the lower cylinder mechanism (3) is configured above the rotor mechanism (2); the upper cylinder mechanism (4) is configured above the lower cylinder mechanism (3); a hopper (5) is mounted above an upper cylinder (409) of the upper cylinder mechanism (4). The upper cylinder mechanism (4) and the lower cylinder mechanism (3) are arranged in the same direction. The piston drive mechanism (6) simultaneously drives two cylinder mechanisms, so that an upper sealing piston (406) and a lower sealing piston (310) are located at a sealing position alternately. The rotor mechanism (2) continuously jets materials in a material bin in the rotating process of a rotor. The pneumatic conveyor reduces the friction between the materials and the sealing pistons, improves the sealing effect and the jetting distance, and reduces dust in the conveying process, which prolongs the service life.
