Solution concentration correction device

Abstract

The invention provides a solution concentration correction device. The solution concentration correction device comprises a solution tank, a quantitative water supply device, a quantitative stock solution supply device, a solution concentration online detection device and a controller; the quantitative water supply device and the quantitative stock solution supply device are both mounted at the top of the solution tank; a liquid outlet pipe communicated with the solution tank is arranged on the solution tank, and the solution concentration online detection device is mounted on the liquid outlet pipe; the solution concentration online detection device comprises a shading shell, a transparent sampling tube, a piston assembly, a sampling head, a strong light emitting device and a light intensity receiving device; the strong light emitting device and the light intensity receiving device are oppositely arranged on two sides of the transparent sampling tube; the controller is connected with the light intensity receiving device to obtain the concentration of a detected solution; and the controller is connected with the quantitative water supply device and the quantitative stock solution supply device so as to control the water adding amount or the liquid adding amount. On-line detection and on-line correction of the concentration of the solution are achieved through cooperation of all the devices, the solution matching precision is guaranteed, and the solution correction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of release agent configuration, and in particular relates to a solution concentration correction device. Background technique [0002] With the rapid development of lightweight vehicles and 5G communications, the structure of die-casting products such as body structural parts, new energy parts, and 5G communication parts is becoming more and more complex, and the requirements for die-casting equipment are higher. In the production process of die-casting products, the release quality of die-casting products directly affects the pass rate of die-casting products, and the release quality of die-casting products is largely affected by the release agent, especially by the concentration of the release agent. A low concentration of the release agent will lead to the failure of the die-casting product to be demolded smoothly, and a high concentration will cause the accumulation of paint on the surface of the product...

AI Technical Summary

Problems solved by technology

Since this configuration method requires multiple sampling tests and measurements, it brings a lot of inconvenience to the configuration of the release agent. The entire operation process is complicated, time-consuming and laborious, and the concentration of the prepared solution is difficult to guarantee.
