Automatic draining device for vacuum pump lines

Abstract

The invention discloses an automatic drainage device for a vacuum pump pipeline, comprising: a main drainage mechanism and an auxiliary drainage mechanism, the main drainage mechanism and the auxiliary drainage mechanism are respectively connected with a vacuum system; the main drainage mechanism and the auxiliary drainage mechanism both include a buffer tank , waste liquid storage tank, waste liquid discharge port, stop valve, buffer valve and blowing valve; the two ends of the upper side of the buffer tank are respectively provided with an air inlet and an air outlet, and the middle part of the buffer tank is provided with a buffer near the air inlet. Gas port, the bottom of the buffer tank is provided with a liquid discharge port, and the buffer tank is connected to the vacuum system through the air inlet and the gas outlet; the waste liquid storage tank is connected to the buffer tank, and the waste liquid discharge port is connected to the bottom of the waste liquid storage tank . Through the above method, the present invention can realize the automatic discharge of the cutting fluid without manual intervention at all, which not only protects the vacuum system, but also improves the production capacity stably.

Description

technical field [0001] The invention relates to the application field of vacuum pump pipelines, in particular to an automatic drainage device for vacuum pump pipelines. Background technique [0002] In the machining industry, when a vacuum pump is used for parts clamping and machining cutting fluid is used at the same time, the negative pressure will cause the cutting fluid to enter the vacuum pump and damage the vacuum system. The existing treatment method is to manually discharge the liquid in the vacuum pipeline. During the treatment, the production needs to be stopped, and the corresponding valve is manually opened to allow the cutting fluid to be discharged from the vacuum pipeline. The production capacity will be reduced due to the shutdown during processing, and the vacuum pressure will be reduced after opening the valve. For the centralized gas supply system, it will seriously affect the production of other connected equipment. Contents of the invention [0003] T...
