AI Technical Summary

Technical Problem

Existing screening devices generate a lot of dust during operation, mainly because dust is shed when steel slag bounces on the screen, causing environmental pollution.

Method used

A screening device including a vibrating screen and a dust removal device was designed. The dust removal device adsorbs and filters dust through a combination of air guide cover, air pump, hose, filter bag and purification barrel, reducing dust emissions. At the same time, the feeding device controls the amount of steel slag fed by adjusting the baffle plate through drive motor and conveyor rod, thereby improving the screening effect.

Benefits of technology

It effectively reduces dust emissions, improves screening efficiency, avoids dust pollution, and enhances the environmental friendliness and screening efficiency of the equipment.

Abstract

This utility model relates to the field of steel slag recycling and treatment technology, specifically a screening device for steel slag recycling and treatment. It includes a vibrating screen with a shock-absorbing frame on its surface and a dust removal device. The dust removal device includes an air guide cover placed on the upper surface of the vibrating screen. Flexible hoses are fixedly connected to both sides of the air guide cover, and an air pump is installed inside the cover. One end of the air pump is the same as one end of the flexible hose. Air holes are opened on the surface of the air guide cover, located above the vibrating screen. A connecting cover is fixedly connected to the other end of the flexible hose. A cloth bag is fixedly connected to the lower surface of the connecting cover, with the other end of the flexible hose located inside the cloth bag. A purification tank is threadedly connected to the lower surface of the connecting cover. This utility model, by incorporating a dust removal device, effectively facilitates dust removal by workers, preventing dust carried on the surface of the steel slag from detaching due to impact, thereby reducing the problem of excessive dust generation during the screening device's operation.
