Blanking tube induced air damping device

Abstract

The present invention relates to a blanking tube induced air damping device comprising a rotating structure, an outer casing disposed at a periphery of the rotating structure, and two bearing seats disposed on the outer casing. The rotating structure comprises a rotating shaft and a choke plate, two ends of the rotating shaft are detachable, flow of material in a blanking tube cannot be hindered via the device, and only induced air is blocked via the device. A gap positioned at the middle of the choke plate is used for enabling the material in the blanking tube to pass through in an unobstructed manner, the choke plate cannot be impacted via the material, the flow of the material cannot be affected via the device, and material blockage can be prevented. If a small amount of scattered material falls on the choke plate, the material rotates downward when weight of the material gathering for a long time breaks the balance; when the choke plate is small in friction coefficient and greaterthan 60 degrees in inclination angle, the small amount of scattered material slides down; under the tensile force of a tension spring, the choke plate returns to an initial position, and material blockage can be prevented even if the scattered material gathers. The choke plate is mainly used for blocking a flowing path of the induced air carried by the material falling down in the blanking tube, and therefore the quantity of the induced air in the blanking tube can be greatly reduced.

Description

technical field [0001] The invention relates to a dust suppression device of a transfer station, in particular to an induced wind damping device of a falling pipe. Background technique [0002] The transfer station is a key link in the bulk material conveying system. The technology of the transfer station affects the efficiency of material conveying, the life of equipment, the safety of system operation and the operating cost of the system. The transfer station usually includes upper and lower belt conveyors, electric three-way coal drop pipes, material guide troughs, idlers and other equipment. The existing transfer station has problems such as coal blockage, large dust, serious wear, and belt deviation. Among them, the dust generated by the transfer station is very serious to the environmental pollution. The dust pollution affects the safe operation of the equipment and endangers the physical and mental health of the operating personnel. [0003] The induced wind in the ...

Problems solved by technology

[0012] Aiming at the defects existing in the existing buffer air locker, the present invention provides a new type of induced wind damping device for the falling pipe to cut off the flow path of the induced wind in the falling pipe of the transfer station, which can greatly reduce the air flow in the coal falling pipe. Thus reducing the amount of dust in the transfer station
