Phosphating slag removal device

Abstract

The invention relates to a phosphating slag removal device, relates to a slag removal device for removing phosphated slags left by production in a phosphating tank, concretely relates to the phosphating slag removal device, and provides the phosphating slag removal device which is simple in structure, convenient to use, energy-saving, environmentally-friendly, safe, reliable, and higher in treatment efficiency. A liquid inlet is formed on the top of a slag removal device body; a liquid outlet is formed under the slag removal device body; a slantways arranged filter screen is arranged in the middle part in the slag removal device body; an inclined scraper blade with the bottom part contacting a surface of the filter screen is arranged on the inclined bottom end of the filter screen; and a slag hole is formed in the top end of the filter screen. A telescoping mechanism is arranged on one side of the scraper blade and is connected with a drive device. A screw extending from top to bottomis arranged on an inner wall of the liquid inlet. According to the phosphating slag removal device provided by the invention, the slag removal efficiency and a slag removal effect are ensured.

Description

technical field [0001] The invention relates to a slag removal device used for removing phosphating slag produced in a phosphating tank, in particular to a phosphating slag removal device. Background technique [0002] At present, it is usually necessary to carry out surface phosphating treatment on the workpiece before electrostatic powder spraying, but the phosphating solution after one use often has some particle impurities, and the yellow rust of the phosphating film will cause the phenomenon of small impurities in pieces, which will cause damage to the workpiece. The coating has poor adhesion and cannot be recycled, which makes the production cost higher. Improper treatment will seriously affect the product quality, and at the same time, it will pollute the environment after a large amount of liquid is discharged. Existing slag removal devices often do not remove slag completely, or the slag removal efficiency is low because the filter screen is blocked. Contents of t...

[0002] At present, it is usually necessary to carry out surface phosphating treatment on the workpiece before electrostatic powder spraying, but the phosphating solution after one use often has some particle impurities, and the yellow rust of the phosphating film will cause the phenomenon of small impurities in pieces, which will cause damage to the workpiece. Coating adhesion is poor and cannot be recycled, which makes the production cost higher. Improper treatment will seriously affect the product quality, and at the same time, the large amount of liquid will pollute the environment.
