AI Technical Summary

Technical Problem

Existing dust treatment devices for sandblasting machines have low filtration efficiency, making it difficult to meet environmental standards. Filter components are prone to clogging, have short service life, and are inconvenient to install and disassemble, thus affecting production efficiency and causing environmental pollution.

Method used

It adopts a multi-stage filtration mode, including a spray assembly, a primary filter plate, and a secondary filter plate. The spray assembly initially purifies the dust, the primary filter plate intercepts large particles, and the secondary filter plate finely filters small particles. The disassembled components facilitate quick installation and fixation.

Benefits of technology

It improves dust filtration efficiency, extends the life of filter components, reduces maintenance costs, reduces dust leakage, meets environmental emission standards, and improves production efficiency.

Abstract

This utility model discloses a multi-stage dust filtration and purification device for sandblasting machines, belonging to the technical field of dust purification devices. It includes: a sandblasting machine body; a connecting pipe fixedly installed on one side of the sandblasting machine body; a purification box installed at one end of the connecting pipe; a spray assembly inside the purification box; and a water tank, which has a short pipe fixedly installed on the top of the water tank and a water outlet pipe at the top of the short pipe. This achieves preliminary dust purification, significantly reducing the filtration load on subsequent filter boxes one and two, extending the service life of the primary and secondary filter plates, and significantly reducing the dust content in the exhaust gas, effectively meeting environmental emission standards, reducing dust pollution to the atmospheric environment, and greatly shortening the time for cleaning and replacing filter plates. It also avoids performance degradation of the entire purification device due to local filtration failure, and the double fixing prevents the filter plates from loosening or shifting during operation.
