Multi-liquid continuous mixing device

Abstract

The invention discloses a multi-liquid continuous mixing device which comprises feed pipelines, a pipeline static mixer and a control device, wherein each one of a plurality of feed pipelines is sequentially provided with a first manual valve, a filter, a material delivery pump, a second manual valve, a check valve, a flowmeter and a regulating valve. A formula is input into a PLC (Programmable Logic Controller), and after the multi-liquid continuous mixing device disclosed by the invention is started, the uniform mixing of multiple liquid is realized in such a way that the PLC controller automatically controls the opening of the regulating valve on line in real time according to the difference value of a set flow and the actual flow; and the multi-liquid continuous mixing device disclosed by the invention has the characteristics of accurate control of the proportioning of various materials, uniformity in mixing, high production efficiency, realization of continuous and stable production and labor intensity reduction.

Description

technical field [0001] The invention relates to a material mixing device, in particular to a continuous mixing device for multiple liquids. Background technique [0002] In the existing engineering construction, in order to improve and adjust the workability, setting time, durability and other properties of concrete, more and more attention has been paid to the application of concrete admixtures in engineering. The addition of admixtures is very important for improving the performance and Improving construction efficiency plays an obvious role, but in the construction process, if the addition of admixtures is not properly controlled, the material ratio is not controlled accurately, and the mixing is uneven, it will seriously affect the performance of the finished concrete and cause potential harm to the quality of the project. . At present, in the production process of compounding concrete admixtures, the compounding method is to weigh various admixtures in advance and put ...

[0002] In the existing engineering construction, in order to improve and adjust the workability, setting time, durability and other properties of concrete, more and more attention has been paid to the application of concrete admixtures in engineering. The addition of admixtures is very important for improving the performance and Improving construction efficiency plays an obvious role, but in the construction process, if the addition of admixtures is not properly controlled, the material ratio is not controlled accurately, and the mixing is uneven, it will seriously affect the performance of the finished concrete and cause potential harm to the quality of the project.

At present, in the production process of compounding concrete admixtures, the compounding method is to weigh various admixtures in advance and put them into the stirring tank, and discharge the materials after stirring. The existing problem is that such a compounding method is affected by man-made , time-consuming, labor-intensive, low proportioning accuracy, low production efficiency, and continuous production cannot be achieved.
