1results about How to "Reduce filter load" patented technology

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.
