Blowing and sucking type cabin flow assisting device

Abstract

The invention discloses a blowing and sucking type cabin flow assisting device which comprises an air flow pipe. The air flow pipe is provided with an input port and a plurality of output ports, wherein the input port is connected with an air source. The air flow pipe comprises an annular pipeline, and the output ports are evenly distributed in the annular pipeline; the output ports are connected with the input ends of electromagnetic three-way valves, one output end of each electromagnetic three-way valve is connected with a blowing and sucking connector, and the other output end of each electromagnetic three-way valve is connected with a dust collector through a negative pressure dust collecting port. Each blowing and sucking connector comprises a filter membrane, sealing pads, a jackscrew and a blowing nut seat, wherein the filter membrane is arranged in the blowing nut seat which is connected with the jackscrew in a threaded mode, and the sealing pads are arranged on the two side faces of the filter membrane respectively. The blowing and sucking type cabin flow assisting device has the beneficial effects that arching conditions are eliminated, the arching problem is solved, and smooth and stable discharging is guaranteed; the device can carry out negative pressure sucking operation and is simple in procedure, low in operation cost and short in working time, the application range can be expanded, and the effect of measures can be improved.

Description

technical field [0001] The invention relates to a bin body flow aid device, in particular to a jet suction type bin body flow aid device. Background technique [0002] At present, the solution to the problem of arching and sheds in the process of unloading powder materials stored in bins is to use dry compressed air to blow into the bins, which can break the arches. However, the gas blown in by the nozzle of the bin body cannot be discharged in time and effectively, which will cause and aggravate the accumulation of positive pressure air in the bin body and form an air plug. The gas accumulates at the bottom when the pressure is not enough to break through the pressure of the material layer. Only when the pressure is greater than a certain level or when it is subjected to external force, it breaks through the pressure of the material layer and is discharged, and the powder can fall smoothly, thus forming a periodic intermittent drop. It is difficult to ensure the stability ...

However, the gas blown in by the nozzle of the bin body cannot be discharged in time and effectively, which will cause and aggravate the accumulation of positive pressure air in the bin body and form an air plug

The gas accumulates at the bottom when the pressure is not enough to break through the pressure of the material layer. Only when the pressure is greater than a certain level or when it is subjected to external force, it breaks through the pressure of the material layer and is discharged, and the powder can fall smoothly, thus forming a periodic intermittent drop. It is difficult to ensure the stability and continuity of powder material feeding
