AI Technical Summary

Technical Problem

In existing technologies, the dust generated during shot blasting is difficult to completely remove, especially the moist dust adhering to the surface of the movable retaining ring, which cannot be effectively removed and affects sewage treatment.

Method used

The dust removal device of the roller conveyor shot blasting machine uses a motor-driven rotating rod to rotate the irregular gear and bevel gear. Combined with the vibration effect of the spring and the scraping function of the scraper, it can effectively clean the wet dust on the surface of the moving retaining ring.

Benefits of technology

This improves the dust removal effect, ensuring that dust can be smoothly discharged from the bottom outlet of the movable baffle ring, thus enhancing the cleaning efficiency of the dust removal device.

Abstract

This utility model relates to the technical field of dust removal devices, specifically a dust removal device for a roller conveyor shot blasting machine. It includes a shot blasting machine, a suction pipe, a dust removal cylinder, a cleaning assembly, and a negative pressure fan. The cleaning assembly comprises a movable retaining ring, a fixed ring, a scraper, a connecting rod, a sleeve, a rotating shaft, and a tension spring. The top of the tension spring is fixedly connected to the inner top wall of the sleeve. A first bevel gear is fixedly connected to the bottom of the rotating shaft. A rotating rod is rotatably connected to the lower surface of the fixed ring via a fixed plate. A second bevel gear is fixedly connected to the surface of the rotating rod, and the first and second bevel gears mesh with each other. In this utility model, when the rotating shaft drives the sleeve, connecting rod, and scraper to rotate, the rotating scraper can remove the residual wet dust on the surface of the movable retaining ring. The trapezoidal shape of the scraper allows the removed dust to flow out through the bottom outlet of the movable retaining ring, further improving the cleaning effect.
