Self cleaning type airlock

Abstract

The application of the invention provides a self cleaning type airlock. The compositions of the self cleaning type airlock comprise an impeller machine shell, an impeller assembly, a control circuit and a cleaning knife assembly. The cleaning knife assembly comprises a pneumatic cleaning knife, a sliding rail, a buffering pad and a blade detecting part, the sliding rail is axially mounted at a discharging opening of the impeller machine shell, and the knife edge of the pneumatic cleaning knife radially extends into the circumference rotatably covered by an impeller; and the blade detecting part comprises an impeller synchronizing wheel mounted at the end cap external shaft end of an impeller shaft and a non-contacting sensor arranged on one side of the impeller synchronizing wheel. The cleaning knife assembly in the technical scheme can cut off and clean impurities entwined on the impeller within an extremely short time, and automatic control operation can be achieved.

Description

technical field [0001] What the application of the present invention relates to is an air lock. Background technique [0002] The air lock is widely used in the fields of rice milling, milling, grain and oil, grain, feed processing, chemical industry, medicine, tobacco, metallurgy, cement and dust removal. It is an important component equipment in the airflow conveying and ventilation and dust removal system. The air shutoff device is installed at the discharge port of the unloader or the cyclone dust collector. Its function mainly has two aspects: one is to ensure the smooth discharge of materials, and the other is to close the working air flow. Its structural composition includes the impeller casing and the impeller casing The impeller is rotated inside, and the upper opening of the impeller casing is connected to the discharge port of the unloader or cyclone dust collector through the flange. During the rotation of the impeller, the materials in the unloader or cyclone du...

AI Technical Summary

Problems solved by technology

During the operation of the air shutoff device, the impeller is easily entangled with debris such as ropes, ribbons, and packaging threads in the material. The increased wear and tear increases the rotational load of the impeller, making it difficult to unload the material, and even block and block the discharge channel. It will also increase the air leakage rate and seriously affect the dust removal ability of the cyclone dust collector

At present, the impeller cleaning operation can only be carried out manually, which has considerable safety hazards and long working hours, which affects the continuous operation of production
