PNEUMATIC TRANSPORT PLANT Russian patent published in 2007 - IPC B65G53/16 B65G53/28 

FIELD: pneumatic transport facilities.

SUBSTANCE: invention is designed for transportation of loose materials. Proposed plant for handling caking and lump powder materials has discharge device with ripper for breaking bridge formed in container, charger with bucket-wheel feeder for breaking lumps, reception of uniform dispensing, device for rubbing through and bringing material into aerated state in aerochamber combined with rubbing through device. According to invention, discharge device is essentially hydraulic cylinder on rod of which platform is secured with fitted on drive whose output shaft is connected with vertical shaft of ripper. Ripper is installed for lowering by means of hydraulic cylinder with cut-in drive and automatic movement upwards after reaching of limit switch in lower position with subsequent disconnection of ripper drive. Charger consists of cylindrical housing, upper cover, pneumovibrator with screen and aerobottom. Pneumovibrator of screen is brought out of housing behind its wall through flexible diaphragm flexible diaphragm. Aerobottom of charger is truncated cone lined from inner side with gas distributing needle-pierced rubber cloth and divided by means of pressure strip into two horizontal sections, each provided with union to feed compressed dried air. Upper cover is provided with charging hatch and branch pipe with filter to let out air into wet dust trap system. Rubbing through device consists of cylindrical housing with round holes in lower part and shaft passing in center of housing with elastic blades attached to cross-members to adjust distance from blades to wall of housing equipment with receiving hopper enclosing over perimeter part of housing with holes and assembled with said aerochamber for fluidizing said material getting into said pipeline.

EFFECT: provision of stable and unfailing operation of plant.
