Reaction kettle weighing system is a kind of production equipment used in industry for automatic and accurate proportioning of different powder or liquid materials according to a certain ratio, which usually consists of weighing instrument, PLC system and upper computer. Including raw material storage body, conveying body, weighing and dosage body, dust removal body, material mixing body and other equipment; dosage mode can be based on the industry characteristics, production process requirements, specific material characteristics, reasonable choice of "incremental" or "decreasing" weighing mode. It has various working modes such as single hopper and single material, single hopper and multiple materials, and multiple hoppers and multiple materials.

According to the predetermined formula, the measuring reaction tank will add a variety of materials into the weighing hopper according to the fixed proportion weight value. When the weighing is displayed to the amount, the materials will be discharged into the inlet of the mixing machine once or several times in steps according to the unloading procedure. It is also possible to control the weight and flow of the material loaded into the weighing hopper through the monitoring system and PLC program, so as to achieve accurate metering and batching. The system has strong stability and high cost performance, and can provide accurate measurement data and control means for production control and management of various industrial sites.

The reactor weighing system issues instructions through the upper computer, and the PLC receives the instructions through a series of programming work, and processes the signal to control various operations. It is an automated production line for conveying, matching, heating, mixing and packaging the whole production process of various different types of materials (solid or liquid). To achieve material transfer, batching control, formula design, production data management and other functions. And it can realize the collection control of multiple ingredients through the network.

The 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 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 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 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.

Temperature-insulated reaction kettle combines weighing sensor, load transfer device, installation connector and other components, and can be connected with various mechanical devices very conveniently. Automatic feeding control, automatic metering, PLC control, man-machine interface for data input and storage in the whole production process. Frequency converter is used to control the stirring speed, which can be set at will.

The weighing device of reaction kettle integrates advanced technologies in various fields such as mechanics, electronic technology and sensing technology. Metering quantitative feeding, reaction process control, discharging and other production process control and data management as one of the batching system. It consists of three parts: touch screen, operation cabinet and power distribution cabinet, and automatically and continuously controls the weighing, feeding, stirring and discharging of powder and liquid materials of the whole set of equipment according to the set formula.
