Feeding system and method for further improving proportioning precision in continuous production and feeding of chemical slurry

Abstract

The invention relates to a feeding system and method for further improving proportioning precision in continuous production and feeding of chemical slurry. The feeding system comprises a control system, a powder measuring and feeding device, a twin-screw mixer, a liquid conveying pump and a flow meter, wherein at least two powder measuring and feeding devices are provided; each powder measuring and feeding device is composed of a powder feeder and a weighing module; the powder feeder is communicated with the twin-screw mixer; the liquid conveying pump is communicated with a liquid inlet of thetwin-screw mixer through a liquid conveying pipe; the flow meter is mounted on the liquid conveying pipe; the control system is used for monitoring liquid feeding flow fed back by the flow meter in real time, monitoring the weight of power materials in the powder feeder fed back by the weighing module in real time and calculating a power feeding flow. The feeding system and method provided by theinvention can automatically calculate and adjust dosages of other materials according to a set feeding proportion by monitoring an actual dosage of the materials and using one of the materials as a reference, and achieves a purpose of further improving the proportioning precision of finished materials.

Description

technical field [0001] The invention relates to a feeding system and a method for further improving the feeding ratio precision of the continuous production of chemical slurry. Background technique [0002] At present, in the production of chemical industry, electronic slurry and other industries, during continuous production, materials of corresponding weight are put into the mixing equipment in a certain proportion for production, but during continuous feeding, there will be bridges, accumulation, import and export of materials Factors such as changes in pressure and temperature lead to certain fluctuations in the flow of input materials. As a result, the more input materials, the greater the error in the total proportion of actual materials. For some industries with high requirements, the input ratio of incoming materials is unstable during production, which is extremely large. Reduced mix consistency. [0003] In addition, the methods and deficiencies currently used by ...

[0002] At present, in the production of chemical industry, electronic slurry and other industries, during continuous production, materials of corresponding weight are put into the mixing equipment in a certain proportion for production, but during continuous feeding, there will be bridges, accumulation, import and export of materials Factors such as changes in pressure and temperature lead to certain fluctuations in the flow of input materials. As a result, the more input materials, the greater the error in the total proportion of actual materials. For some industries with high requirements, the input ratio of incoming materials is unstable during production, which is extremely large. Reduced mix consistency

[0003] In addition, the methods and deficiencies currently used by enterprises in powder feeding are as follows: 1. Using traditional manual weighing and then feeding directly, the powder in the workshop is flying, the environment is harsh, and it is not good for human health; 2. Some companies use Currently popular feeding system on the market, but it is often necessary to fill the hopper, measure the rated weight, stop feeding, and then start unloading. In order to improve work efficiency, if materials are loaded and loaded at the same time, the weighing module cannot accurately read the data, and continuous loading and unloading while accurate measurement cannot be realized, which cannot meet the requirements of the enterprise
