Automatic drainage system of air compressor

Abstract

The invention discloses an automatic drainage system of an air compressor. The system comprises a high-power air compressor, an air compression unit, a main pipe, a micro-air-consumption automatic drainer and an aftertreatment unit; the high-power air compressor is connected with one end of the main pipe; the air compression unit consists of multiple low-power air compressors; the aftertreatment unit consists of multiple aftertreatment equipment; each low-power air compressor is connected with single aftertreatment equipment through a one-way valve; the one-way valves and the aftertreatment equipment are connected through arrangement of branches and the main pipe; the other end of the main pipe is connected with the micro-air-consumption automatic drainer; the micro-air-consumption automatic drainer comprises a water inlet valve, a water outlet valve and a liquid storage pipe; and a time relay is connected between the water inlet valve and the water outlet valve for controlling openingand closing of the water inlet valve and the water outlet valve. Multiple electromagnetic valves are reduced in the whole set of system; and water is drained in a time interval mode, so that the airloss is lower, and the electromagnetic valves are difficultly damaged. Meanwhile, the air compressors are serially connected, so that the normal work of the aftertreatment equipment cannot be influenced if one air compressor is broken down, and the production in next procedures can be guaranteed.

Description

technical field [0001] The invention relates to the field of copper strip processing, in particular to an automatic drainage system for an air compressor. Background technique [0002] The water content from the air compressor to the post-treatment is relatively large, and drainage is often required. Manual drainage is often forgotten, and the post-treatment contains alumina. If there is too much water, it will interfere with the reaction. The existing equipment is a one-to-one connection between a single air compressor and a single post-processing unit, a small liquid storage tank and a liquid level sensor are installed in the middle, and the drainage of the liquid storage tank is automatically controlled by the liquid level sensor. This drainage method has a small storage tank and a small displacement, but the compressed air produces a large amount of water, so the solenoid valve operates every 20 to 30 seconds, and the solenoid valve is easily damaged. At the same time, ...

AI Technical Summary

Problems solved by technology

This drainage method has a small storage tank and a small displacement, but the compressed air produces a large amount of water, so the solenoid valve operates every 20 to 30 seconds, and the solenoid valve is easily damaged.

At the same time, it is easy to cause a very large loss of compressed air during drainage, resulting in unstable pressure and air blockage. When the air is blocked, it will not drain and malfunction.

This one-to-one connection mode, once the air compressor breaks down, the post-processing equipment will not work and needs to be shut down, which will affect the next production process
