Zinc residue pump for cold-rolled strip steel galvanization production line

Abstract

The invention provides a zinc residue pump for a cold-rolled strip steel galvanization production line. The zinc residue pump is applied to the technical field of the cold-rolled strip steel galvanization production line. A zinc residue pump shell (1) of the zinc residue pump is connected with a drive motor (2). A planetary reducer (3) and an impeller shaft (4) are arranged in the zinc residue pump shell (1). The drive motor (2) is connected with the input end of the planetary reducer (3), and the impeller shaft (4) is connected with the output end of the planetary reducer (3) and provided with blades (5). The drive motor (2) is connected with a control component (6) capable of controlling start and stop of the drive motor (2). The zinc residue pump shell (1) is communicated with a nitrogen tank (8) through a nitrogen conveying pipeline (7). The zinc residue pump is simple in structure, it is ensured that zinc residues on the surface of galvanizing zinc are effectively and reliably pumped away, meanwhile, maintenance efficiency and running stability can be improved, the maintenance efficiency of the zinc residue pump can be remarkably improved, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention belongs to the technical field of a cold-rolled steel strip galvanizing production line, and more specifically relates to a zinc slag pump used in a cold-rolled strip steel galvanizing production line. Background technique [0002] In the cold-rolled strip galvanizing production line, the zinc slag floating on the surface of the zinc liquid inside the zinc nose equipment is an important factor affecting the surface quality of the galvanized strip steel. Therefore, zinc slag is designed on both sides of the skirt at the front end of the zinc nose The zinc dross pump pumps away the zinc dross on the surface of the zinc liquid to reduce the content of zinc dross in the zinc liquid to meet the requirement of improving the surface quality of the galvanized steel strip. Because the working environment of the zinc slag pump is very harsh, the use of the zinc slag pump has a fixed cycle, and spare parts need to be replaced frequently, and the loa...

AI Technical Summary

Problems solved by technology

Because the working environment of the zinc slag pump is very harsh, the use of the zinc slag pump has a fixed cycle, and spare parts need to be replaced frequently, and the load-bearing capacity and rigidity of the front end of the zinc nose are limited. The efficiency of maintenance and the stability of operation are affected, and the demand of the production line cannot be met.
