AI Technical Summary

Technical Problem

In existing automatic chemical supply switching equipment, the filter mechanism needs to be replaced regularly, and the cleaning mechanism is impractical, which reduces the equipment's usability and poses a risk of chemical contamination.

Method used

An automatic chemical switching supply device was designed. High-pressure gas is introduced through an air inlet cylinder connected to a compressor. The filter screen is automatically cleaned using a top plate and sealing structure. Impurities are simultaneously scraped off and collected through a combination of scraper strips and storage rings.

Benefits of technology

It improves the service life of the filter screen, enables synchronous cleaning of filter components and automatic collection of impurities, enhances the automation level and practicality of the equipment, and solves the problem of impurity collection after filter screen cleaning.

Abstract

The application belongs to the technical field of chemical supply equipment, and discloses a kind of chemical automatic switching supply equipment, including box, feed pipe and discharge pipe, the outer surface of discharge pipe is equipped with electromagnetic valve, the top of box is also equipped with motor, the upper portion of box inner wall is fixedly installed with support ring and fixed ring, the inner wall of fixed ring is fixedly connected with filter screen, the bottom of box inner wall is fixedly installed with air inlet cylinder.This equipment realizes the filtration of chemicals, synchronous cleaning of filtering components, and subsequent impurity scraping and collection, forming a complete closed loop in terms of filtration, which helps to improve the degree of automation in chemical storage and supply, especially the connection between the scraping strip and the storage ring. After rotating and feeding, the centrifugal force generated by the rotation of the scraping strip automatically collects the impurities into the interior of the storage ring, improving the practicality of the scraping strip.
