Preparing system and preparing method of mixed liquid

Abstract

The invention provides a preparing system of mixed liquid. The preparing system of the mixed liquid is used for preparing the mixed liquid and maintaining the concentration stability of the mixed liquid, and comprises a raw liquid unit, a diluent unit, a mixing and preparing device and a central control unit, wherein the raw liquid unit and the diluent unit are respectively communicated with the mixing and preparing device, the raw liquid unit is provided with a liquid level sensor, an electromagnetic valve is arranged between the diluent unit and the mixing and preparing device, a voltage stabilizer is arranged between the electromagnetic valve and the mixing and preparing device, the electromagnetic valve is electrically connected with the voltage stabilizer, the liquid level sensor is in communication connection with the central control unit, and the central control unit controls and is in connection with the electromagnetic valve. The preparing system of the mixed liquid disclosed by the invention has the advantages that the constancy of the liquid level of the raw liquid and the pressure flow rate of the diluent is maintained in the work process, so that the concentration stability of the mixed liquid is maintained; when the liquid level of the raw liquid or the flow rate of the diluent is changed, the system automatically stops working, and the condition that no unqualified mixed liquid enters a production system is ensured. The invention also relates to a preparing method for preparing the mixed liquid by using the preparing system.

Description

technical field [0001] The invention relates to a mixed liquid blending device, in particular to a blending system for blending mixed liquid and maintaining a stable concentration of the mixed liquid and a blending method using the blending system to configure the mixed liquid. Background technique [0002] The deployment of the traditional mixed solution has the following methods: [0003] 1. Manual blending: it is artificially blended in the measurement process according to the ratio of diluent and stock solution. Existing problems: high labor intensity, uneven mixing, measurement problems, inaccurate concentration, and large influence of human factors. [0004] 2. Semi-automatic allocation using Venturi tube: Although this allocation method improves work efficiency, due to some objective and realistic reasons, such as Figure 5 As shown, the concentration of its deployment fluctuates greatly, and the concentration gradually decreases with time. There is no repeatability,...

Existing problems: high labor intensity, uneven mixing, inaccurate concentration in the metering scale, and large influence of human factors

[0004] 2. Semi-automatic allocation using Venturi tube: Although this allocation method improves work efficiency, due to some objective and realistic reasons, such as Figure 5 As shown, the concentration of its deployment fluctuates greatly, and the concentration gradually decreases with time. There is no repeatability, and the mixed solution prepared cannot meet the requirements for use.

[0005] Because the concentration of the prepared mixed solution is unstable, it cannot meet the requirements of production or life. For example, if the concentration of cutting fluid is not stable, it will cause corrosion of equipment or workpieces, and the surface finish of workpieces will be low. Problems such as decreased tool life or smelly solution
