The weighing of oil heating reactor is realized by the computer distributed control system itself, that is, no additional computer hardware is attached. With the control system composed of network communication, the requirement for the control software of the reactor is not only how powerful its function and how rich its content, but the demand for the user's redevelopment ability of different objects is becoming increasingly important.

The hardware of the temperature control system mainly consists of a frequency converter, temperature control, and PLC process control components. After receiving the speed and torque signals from the PLC, the frequency converter controls the frequency converter drive to set the corresponding speed and direction to make the motor operate. At the same time, it transmits the feedback signal back to the PLC to monitor whether the armature temperature, speed, and torque exceed the set values. The PLC process control is based on the on-site signals to control the operation of the feed-in, main unit, conveyor, and temperature unit, and provides corresponding working status displays for the operators to monitor.

The automatic batching system is developed with the central processing system as the core, each weighing controller controls one weighing scale, which directly controls the batching process and accomplishes the tasks of data collection, processing, storage and display, fault detection and alarm, data communication, etc. The automatic batching system can be used for the real-time display of the batching process and the data communication. Real-time display of the dosage process, data storage and report printing, and directly involved in the control of the feeding and discharging action of each scale. The control system is a multi-channel data acquisition unit, installed in the production site, responsible for the data acquisition and local display of the weighing signals and liquid level signals, and sends the acquired data to the host computer for processing through the serial bus.

The adjustment batching system sends a full material signal to the PLC through the weighing module. The PLC then controls the conveyor to stop the screw. When the material reaches the minimum storage level, the weighing module sends a signal to start the conveyor's screw rotation. The step motor drives the conveying pipe to rotate, enabling the switching of material transportation between different branches. The step motor rotates the rotating support frame, thereby driving the screw conveying pipe to rotate and connecting it to one of the discharge outlets. This achieves the functions of arbitrary switching of the system distribution machine's conveying pipeline, automatic opening and closing of the electric valve, automatic adjustment of the screw conveying discharge speed, and automatic starting and stopping of the screw.

Reaction pot weighing system to be weighed after the start of the weight signal and speed signal to the weighing instrument, through the amplification of the A/D conversion, calculated instantaneous flow and cumulative amount, and displayed in the field weighing instrument. The indicator uploads the signals to the PLC module, the PLC analog input module collects the weight signals and speed signals from the screw and feeding device, and carries out the self-tuning operation according to the parameters set by the user, and the level weight of the materials in the reaction tank measured by the weighing module of the reaction tank regulates the flow rate of each downstream port of the dosage reaction tank, so as to guarantee the balance of the inlet and outlet of the mixing and storage tanks.

The distillation tank weighing system adopts a computer with stable performance to complete the data acquisition and communication processing, which is convenient to provide processing accuracy and cost reduction, and the data output and management are carried out through the COM communication interface of the computer itself; Mitsubishi F900 touch screen is chosen to replace the conventional weight indicator to do the human-machine interface, which makes the programming of the interface between PLC and weight indicator become simpler, and enables the display function to be enhanced. The weighing system is to add two or more kinds of materials to the mixing tank automatically according to a certain weight ratio, and then automatically discharges the materials after mixing to meet the predetermined requirements.

The weighing system of the reaction tank is transmitted to the central control room for centralized monitoring and management through high-speed network, and the host computer of the central control room also transmits control commands to the PLC measurement and control terminal through high-speed network to implement decentralized management of each unit. Integrating computer technology, automatic control, communication technology, weighing technology as a whole, its control function is perfect, display, operation is centralized, data processing is convenient, installation, maintenance is simple, the system is easy to expand.

Self-Control 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.
