Problems solved by technology

[0003] In the prior art, in the production process of Shi Yingchao fine powder, the pressure in the pipeline is mainly controlled by manual operation, and the accurate monitoring of the automation of its production process cannot be realized, so that the pressure in the pipeline is unstable, resulting in particles The distribution is unstable and uneven, and the filling ratio when used as a filler is not easy to control. It is necessary to constantly adjust the filling ratio of the filler, which brings a lot of inconvenience to industrial production.

Abstract

An automatic controlling device for preparing quartz ultrafine powder comprises a breaking device, a sorter, an air inducer and a communicated channel connecting the breaking device, the sorter and the air inducer as well as a detection device and a control device; wherein the detection device is used for detecting pressure in the communicated channel and sending a detection signal to the controldevice; the control device is used for receiving the detection signal and control the air inducer to operate according to the detection signal, so that the pressure value in the communicated channel is balanced. The detection device and the control device are added in the device for preparing quartz ultrafine powder, automatic control is realized, pressure balance in the communicated channel is constant, so that the prepared quartz ultrafine powder particles have good stability and uniformity and quality of quartz ultrafine powder product is improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an automatic control device for preparing super fine powder of quartz. Background technique [0002] Quartz powder is a high-quality neutral inorganic filler, widely used in plastics, rubber, coatings, electronics, electrical and high-tech products and other industries. Especially in the period of rapid development of the modern electronic industry, a large amount of epoxy molding compound needs to be used in semiconductor device packaging materials, and high-purity ultra-fine quartz powder is its main filler. It has the characteristics of excellent dielectric properties, low thermal expansion coefficient, high thermal conductivity, and low price compared to epoxy resin. Adding it as a filler can reduce the thermal expansion coefficient of the packaging material, water absorption, molding shrinkage rate and cost rate. Reduced, and improved heat resistance, mechanical strength, d...
