TheWeighing reactor control system controls the dosing according to A certain proportion, at the same time gives the feeding system according to the material level information of each reaction tank, sets the relationship between the ratio of raw materials and the arrangement sequence of the total feed quantity meter, sets the weight of the equipment under each reaction tank through the communication of the upper computer, and sends the weight signal and speed signal to the weighing instrument after the weighing system is started. Instantaneous flow and accumulation are calculated and displayed in the field weighing instrument. Self-tuning operation is carried out according to the parameters set by the user. If there is a deviation between the set value and the current value, the PLC analog module will adjust according to the need.

The lubricating oil dosing system realizes PLC on-line control, the valve position and discharger position signal detection adopts load sensor, and the bin location adopts heavy weight type material level meter, which can realize continuous warehouse location detection. The control unit is mainly a touch screen, PLC as an auxiliary control system, man-machine interface display ratio parameters (formula) and monitoring and recording real-time data. According to the speed of weighing material, the lead amount is provided. When the weight is detected to reach the set value, the lead amount is subtracted, and the control instrument closes the feed valve. The lead amount can be manually corrected or automatically corrected, so that the control instrument can control the batching precision of each batching scale to reach the set target value.

The automatic control system of the reactor is composed of automatic batching design, feed and discharge all controlled by computer, dynamic weighing module, precision amplifier, A/D converter, microcomputer, monitor, printer and execution system. The weight required for various materials is set through the touch screen, and automatically transported to the ingredients in order for automatic weighing and flow control, so as to achieve accurate measurement and batching.

The Mix weighing system of reaction pot is a complete set of automatic equipment for dynamic weighing and batching control through electrical control management and visual man-machine software configuration. According to the process requirements, the weight and flow of the material loaded into the weighing hopper are controlled by the monitoring system and PLC program, so as to achieve accurate measurement and batching. With strong stability and high cost performance, it can provide accurate measurement data and control means for production control and management of various industrial sites.

The mixing and weighing system adopts Siemens PLC, circuit breakers, relays, inverters and terminals, which can complete the equipment automation and process automation control. At the same time, the configuration control means to collect the data and adopt the high-end configuration software as the upper computer, through which commands are issued to manage the automation equipment and process. Standard industrial computer software and hardware platform as an integrated carrier to replace the traditional system, with strong adaptability, openness and good characteristics.

The Mixing reaction pot weighing system converts the digital signal into digital signal through internal amplification A/D and transmits the digital signal to the CAN bus through the communication sub-module. The instantaneous flow rate of the material can be measured, and the analog signal from the weighing module and the motor frequency conversion speed regulation can be received in the system, and the instantaneous flow rate and cumulative flow rate can be displayed after integration. At the same time, the instantaneous flow is sent to the computer system with 4~20mA analog current signal as the input signal, and the computer compares the signal with the set value and outputs 4~20mA analog current signal through the inverter to control the speed of the feeding motor, realizing the closed-loop control of the material discharge flow.

The Proportioning reaction tank weighing system is a process in which two or more kinds of materials are automatically and quantitatively added to the mixing tank according to a certain weight ratio, and the materials are automatically discharged after mixing to meet the predetermined requirements. The electrical signal representing the weight generated by the weighing module and weighing instrument is collected by PLC and computer after the signal amplification module. When the predetermined weight is reached, the PLC drives the motor to open the pneumatic valve of the measuring tank, the material enters the reactor, and the stirring motor is started at the same time. After the stirring reaches the specified time, the discharge port is opened and the material is discharged.

The Stir weighing system of the reaction tank is divided into material storage, batching, metering system and electrical control system, which is mainly composed of PLC, weighing instrument, weighing module and signal distributor. PLC is used to configure the start and stop and the opening and closing of the warehouse door and other switch quantity control, detect the status of the warehouse door and operation configuration, and implement system interlock for the batching system. With the results of weight signal acceptance, fast and slow loading control and self-tuning of overimpulse, it can modify the input and parameters of the material side.

The weighing system provides man-machine interactive interface, and completes the functions of controlling information input, data management, data display, storage, statistics and reporting, etc. The industrial computer inputs the weight of ingredients through the host keyboard, generates the weight of various materials according to the proportion of raw materials, and transmits them to PLC through communication. In the process of batching, dynamic real-time monitoring is carried out, and other switching values in the detection and control system sent by each slave machine are collected regularly, and the weight signals of each material are collected in real time and compared with the given signals to determine the next control scheme, and at the same time, the weight signals are transmitted to the upper computer.
