Automatic detection and dosing apparatus of metal surface treatment agent

Abstract

The invention discloses an automatic detection and dosing apparatus of a metal surface treatment agent. The automatic detection and dosing apparatus comprises a control cabinet main machine and a dosing system, wherein the dosing system comprises a chemical solution treatment pond, a chemical solution storage apparatus, a chemical solution detection apparatus, a measuring pump and a circulating pump, the chemical solution treatment pond is connected with the chemical solution storage apparatus by virtue of a chemical inlet pipeline, the measuring pump is arranged on the chemical feeding pipeline, the circulating pump is connected with a solution inlet pipe and a solution outlet pipe, the solution inlet pipe is connected to the bottom of the chemical solution treatment pond, the solution outlet pipe is connected to the top of the chemical solution treatment pond, the middle part of the solution outlet pipe is also connected with a detection pipeline, the detection pipeline is provided with a U-shaped circulation pond, the chemical solution detection apparatus is located on the bottom of the U-shaped circulation pond, and the control cabinet main machine is separately electrically connected with the measuring pump and the chemical solution detection apparatus. By adopting the technical scheme, the problems of the existing metal surface treatment agent adding way that the detection concentration and chemical solution addition amount are inaccurate and the metal surface treatment effect is influenced can be solved.

Description

Technical field [0001] The invention belongs to the technical field of metal surface treatment agent circulation, and specifically relates to an automatic detection and dosing device for metal surface treatment agents. Background technique [0002] Metal surface treatment agent refers to the general term for chemical agents that perform various treatments on metal surfaces. Metal surface treatment includes substrate pretreatment such as degreasing, rust removal, phosphating, rust prevention, etc. It is prepared for metal coating technology and metal protection technology. The quality of the substrate pretreatment is very important for the preparation of the coating and the use of metal. Big impact. [0003] Since the metal surface treatment agent consumes a certain amount of metal surface treatment, it is necessary to replenish the chemical solution in the chemical solution treatment tank in time to avoid the low concentration of the chemical solution affecting the metal surface t...
