A jet-suction chamber flow-aid device

Abstract

The invention discloses a blowing and suction type chamber flow-aiding device, which includes an airflow pipe, the airflow pipe is provided with an input interface and several output interfaces, wherein the input interface is connected with an air source, and the airflow pipe includes A circular pipeline, and the output interface is evenly distributed on the circular pipeline; the output interface is connected to the input end of the electromagnetic three-way valve, and the output end of the electromagnetic three-way valve is connected to the injection suction joint, and the other end is collected by negative pressure. The dust interface is connected with the dust collector; the injection and suction joint includes a filter diaphragm, a sealing gasket, a top wire and an injection female seat; the injection female seat has a built-in filter diaphragm, and the injection female seat and the top Screw thread connection, wherein both sides of the filter membrane are provided with sealing gaskets; the beneficial effects brought by the invention are: it eliminates the condition of arching, solves the problem of arching, ensures smooth and stable feeding, and the device can carry out negative pressure Suction operation has simple process, low operation cost and short working hours, which can expand the application range and improve the effect of measures.

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
