Device for removing rust and then purifying dust for steel pipeline anti-corrosion production line

Abstract

The invention discloses a device for removing rust and then purifying dust for a steel pipeline anti-corrosion production line. The device comprises a rust removal tank, a purifying inner tank, a purifying outer tank and a washing tank, wherein conveying ports are symmetrically formed in the left end and the right end of the rust removal tank, a rust removal pipe penetrates through the left conveying port and the right conveying port, a rust removal mechanism in the rust removal tank removes the rust on a rust removal pipe, a material guide part is arranged at the lower end of the rust removaltank, the lower end of the material guide part is connected with the purifying inner tank, a conical filter screen is arranged in the inner part of the purifying inner tank, filter holes are evenly distributed in the surface of the conical filter screen, the lower end of the conical filter screen is connected and fixed with the inner wall of the purifying inner tank, the conical filter screen isprovided with a residue discharge port in the inner wall of the purifying inner tank, and the tip of the top part of the conical filter screen and a lower port of the material guide part mutually correspond. The device is simple and reasonable in structure, the recycling of water is realized, the exhaust gas is effectively purified, the environment pollution caused by the device is reduced, the air quality is guaranteed, and the practicality of the device is strong.

Description

Technical field [0001] The invention relates to the technical field of anti-corrosion and rust removal equipment, in particular to a dust purification device after rust removal in a steel pipeline anti-corrosion production line. Background technique [0002] At present, the country pays more and more attention to environmental protection, and puts forward high requirements on dust control in the production process of enterprises. Therefore, the discharge of dust generated in the production process is a link that requires special attention. For steel pipe anticorrosion plants, the recovery of dust produced by shot blasting and rust removal of steel pipe surfaces is a problem. [0003] At present, all anti-corrosion plant steel pipe derusting dust recovery systems adopt the secondary form of cyclone dust collector and filter cartridge dust collector. In the normal life cycle of the filter element, the filter element often fails locally, resulting in the recovery rate of rust dust Re...

Problems solved by technology

[0003] At present, the dust recovery system for steel pipe derusting in all anticorrosion plants adopts the secondary form of cyclone dust collector and filter cartridge dust collector. During the normal service life of the filter element, the filter element often fails locally, resulting in a low rust dust recovery rate. Reduced, a large amount of dust-containing air is directly discharged to the outside, causing environmental pollution in the factory area
