Continuous cleaning device for vacuum pump and method thereof

Abstract

The invention discloses a continuous cleaning device for a vacuum pump and a method thereof. The device comprises a cleaning solution supply system, wherein the cleaning solution supply system is provided with a cleaning solution storage barrel filled with cleaning solution, a cleaning solution delivery pipeline and a switching valve arranged on the cleaning solution delivery pipeline; the cleaning solution delivery pipeline is connected with the cleaning solution inlet which is arranged on the pump body of a vacuum pipe and communicated with the inner cavity of the pump body; or the cleaning solution delivery pipe and the work solution delivery pipeline of the vacuum pump are connected with the inlet of a shuttle valve; and the outlet of the shuttle valve is connected with a work solution inlet on the pump body of the vacuum pump. By using the method, the work solution is regularly changed into the cleaning solution to clean the inside of the vacuum pump. The continuous cleaning device for the vacuum pump and the method need not halting in a cleaning process without influencing production or detaching equipment, save time and labor and have no consumption on equipment. Therefore, the device and the method ensure that the vacuum degree of the vacuum pump is not reduced, and the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of vacuum pump cleaning devices, in particular to a vacuum pump continuous cleaning device and a method thereof. Background technique [0002] During the extrusion molding process of the light guide plate, due to the moisture absorption of the material used or the material itself contains volatile substances, the extruded product is mixed with air bubbles and pores, which affects the product quality. The vented screw extruder is used to solve this problem. . The vented screw extruder has a primary extrusion part, a venting part and a secondary extrusion part. The material is melted and plasticized by one extrusion, and enters the exhaust part, and the screw groove of the exhaust screw suddenly becomes deeper, so that the pressure of the material in the exhaust part drops suddenly, and the original compressed gas and vaporized volatilization in the polymer The substance is released here, and the molten plas...
