The application in the production of blending ingredients in the reaction kettle is mainly to blend the material according to a certain blending proportion and the corresponding addition. In this process, various reagents are poured into the mixing tank, and the corresponding auxiliary pump is used for circulation, and then the blending is evenly mixed by electric stirring to form a new blending material; Combined with the actual situation, the application of the mixing technology in the batching production has the obvious characteristics of simple process equipment, convenient operation and small investment. The whole automatic Batching system is composed of industrial computer, PLC, industrial weighing instrument, frequency converter, vibration motor, mixer, weighing module, screw conveyor belt, etc. In the process of PLC control, the upper computer uses the upper computer connection command to monitor the operating status and data area content of the lower computer, and reads the real-time data of the internal status of the PLC and weighing instrument in real time. And display on the host computer.

The weighing and batching system can complete the automatic feeding and batching of various ingredients, which integrates material storage, quantitative feeding, weighing and sealing transportation. The whole process is controlled by microcomputer and has a high degree of automation. Each single scale advanced technology, excellent performance, the whole system structure is compact; Through the operation of the terminal equipment, the input and output of various data under the multi-material and multi-formula environment can be completed. Conveniently output or display the set data on the terminal screen, this is a centralized monitoring system to achieve automatic control, using PLC, man-machine and configuration software to achieve automatic control; With on-site monitoring, fault alarm, data acquisition, recording, statistics, query and printing automation process.

The feeding system displays the flow rate, load, cumulative value and temperature in real time. The temperature indication is transmitted through the on-site temperature weighing instrument, and the pressure indication is transmitted through the on-site pressure display instrument and the electric flow of the motor to the central control room for centralized display. The inverter is equipped with an automatic switching switch to communicate with the main control computer. The automatic weighing material control unit is mainly weighing and batching instrument, PLC as an auxiliary control system, computer man-machine interface display ratio parameters (formula) and monitoring and recording real-time data. In the automatic control mode, click the automatic batching "start" button in the pre-dispensing process screen, or the "start" button in the front dispensing control cabinet, and the weighing control instrument will open the material valve according to the set formula. If the system detects that one of the batching valves is not closed, an alarm will occur and enter the suspended state. Each weighing valve speed is provided with the lead, when the control instrument detects that the weight of the weighing material reaches the set value, the Electronic scale will subtract the lead, and the control weighing instrument will close the feed valve. The amount of lead can be manually corrected or automatically corrected, so that the precision of each batching of the control weighing instrument can reach the set target value.
