Improved screw phosphorizing device

Abstract

The invention discloses an improved screw phosphating device, which comprises a phosphating tank and a loading mechanism placed in the phosphating tank, and the phosphating tank includes a main body of the phosphating tank, a pump group, a first tank body and a second tank body , a filter body, a cleaning mechanism, a collecting mechanism and a slag outlet, the inner bottom surface of the first tank body is provided with a second tank body, the bottom of the second tank body is conical, and the first tank body The bottom of the tank is provided with a slag outlet connected to the bottom of the second tank, the output end of the slag outlet is provided with a collecting mechanism, the upper end of the second tank is provided with a filter body, and the first tank The body is provided with a cleaning mechanism for cleaning the inner wall of the filter. The output end and input end of the pump group are respectively connected with the main body of the phosphating tank and the first tank body, and the main body of the phosphating tank is connected with the second tank body through a pipeline. Compared with the prior art, the screw can be turned and bounced continuously, the phosphating effect is greatly improved, and the phosphating slag can be separated without affecting the production.

Description

【Technical field】 [0001] The invention relates to the technical field of an improved screw phosphating device. 【Background technique】 [0002] Phosphating is a commonly used pretreatment technology, which should belong to chemical conversion film treatment in principle, and is mainly used in phosphating of steel surface. Phosphating is a process in which chemical and electrochemical reactions form a phosphate chemical conversion film, and the formed phosphate conversion film is called a phosphating film. The purpose of phosphating is mainly to provide protection for the base metal, prevent the metal from being corroded to a certain extent, use it as a primer before painting, improve the adhesion and anti-corrosion ability of the paint film layer, and reduce friction in the metal cold processing process Lubrication. [0003] When phosphating screw products, a hanging basket is generally used as a phosphating tool. The disadvantage is that because the parts and products are ...

Problems solved by technology

[0003] When phosphating screw products, a hanging basket is generally used as a phosphating tool. The disadvantage is that because the parts and products are relatively static in the hanging basket, the phosphating film of the screw product is uneven, so that the phosphating product cannot be finished. satisfy the needs of clients

[0004] During the phosphating process, there will be precipitated substances - phosphating slag, which is easy to block the nozzles, pipelines and water pumps, which not only wastes medicine but also increases the workload of slag cleaning, affecting production
