Material mixing system

Abstract

The embodiment of the invention discloses a material mixing system. The material mixing system has the advantages that the proportion of two materials is accordant with a preset mixing proportion, the two materials are accurately mixed, and the problem that the two materials cannot be uniformly and accurately mixed is avoided. The material mixing system comprises a discharging pump, a first flow meter, a second flow meter, a multi-stage pump, a first pipeline, a second pipeline, a regulating module and a calculating module, wherein the discharging pump is connected with the first flow meter through the first pipeline; the multi-stage pump is connected with the second flow meter through the second pipeline; the calculating module is used for calculating a regulating frequency value according to a preset proportion value, the regulating frequency value is calculated by virtue of the proportion value and a difference value between a second flow and a target flow, and the target flow is calculated by virtue of the first flow and a preset mixing proportion; the regulating module is used for regulating the operation frequency of the multi-stage pump according to the regulating frequency value so as to enable the second flow to reach the target flow.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a material mixing system. Background technique [0002] With the progress and development of production industrialization, various production processes will be used in industrial production, among which the material mixing process occupies an important position in industrial production. [0003] At present, the flow addition method is generally used to mix the two materials online. The specific steps are: during the transportation of material A, material B is added to the pipeline for transportation. At this time, it is generally realized by a diaphragm metering pump. The diaphragm metering pump has the characteristics of large head and capable of metering, so that material B can enter material A by pressure, and the addition amount can be controlled. The specific method is to monitor the flow of material A in real time, and adjust the flow of the metering pump in proportion to the change...

Problems solved by technology

[0004] However, the flow addition method generally requires a higher pumping pressure. The diaphragm metering pump uses the reciprocating movement of the diaphragm to push the material B into the pipeline through which the material A flows. The adding process of the material B is not continuous, but pushes Adding once at a time, the flow rate is unstable, and the pushing material is not uniform each time, it is difficult to ensure the accuracy of feeding, resulting in the problem of uneven and inaccurate mixing
