The Instruction Dosing System utilizes PLC as the central control area to complete the whole process of weighing and feeding. The PLC central control area sends out a signal to start the corresponding solenoid valve to inject the liquid into the reaction kettle, and at the same time, the weighing module starts to work. When the amount of liquid in the reaction kettle increases to the same value as the weight set by the quantitative setting finger, the central control area receives the action signal from the weighing module, and immediately closes the solenoid valve for adding liquid and stops adding liquid. Automatically start the stirring switch, the control area sends out the instruction to start the corresponding solenoid valve of the mixer and the timer set by the program starts to time, the mixer stirs the solution evenly; when the timer time reaches the set value, the control area sends out the instruction to close the solenoid valve and stops the stirring.

The human-machine interface of the Spiral feeding system is developed based on the operating system, which can meet the requirements of monitoring and controlling the production process as well as archiving and processing the production data. The user interface drawn by WinCC is simple and easy to operate with a good human-machine interface, which can dynamically display the operation status of various equipment on the site and the various parameters of the dosage operation. The operator can also flexibly control the starting and stopping of the field equipment and change the operating parameters of the dosage according to the needs.

The Sequence automatic feeding system introduces advanced industrial control computer machine and PLC and DCS system, adopting decentralization, networking and intelligence to ensure the reliability and long-term stability of dosage. Adopting transfer pump to realize liquid dosage with kettle as the control unit, each kettle is set up accordingly to set the recipe boundary for different recipe feeding and conveying, which can flexibly cope with the demand of different recipes for different production batches of tasks.

The automatic hopper system utilizes the advantages of data acquisition, control technology and configuration software to develop a mechanism with mutual monitoring between the computer and the weighing instrument and various alarm mechanisms, which not only sends an alarm signal even if the computer is dead, but also continues to operate in the original state, thus guaranteeing the quality of the product and the yield. All data can be saved. In order to ensure data efficiency, the default data saving method is time-driven, i.e., when the ratios are modified, when an alarm occurs, or when other pre-defined events occur. The system also provides querying of statistical data, such as yield reports. Data query can be realized not only locally but also on any networked computer.

The Weighing Hopper System is a general purpose data acquisition and monitoring software for industrial automation, capable of acquiring all kinds of information from the automation process and dosage, displaying the information in a graphical and other easier to understand way, transmitting the important information to the relevant personnel by various means, carrying out the necessary analysis and processing of the information and storing it, sending out the control commands, etc. It provides a wealth of functions for industrial automation and dosage, configuring and other relatively easy tasks to build up the dosage functions you need. The DXD200 provides a wide range of functions for industrial automatic dosage, and it is easy to set up the dosage functions you need by configuring them.

The powder batching system is equipped with a weighing module in the feeding loop, forming a closed-loop control system consisting of the weighing module, a screw conveyor, and a PLC. The feeding method is quantitative control by quality flow rate controlled by the PLC. During production, the quality flow rate for feeding is preset according to the capacity requirements of the silo. The control unit of the PLC automatically adjusts the feeding speed of the screw conveyor based on the deviation between the actual feeding quality flow rate detected by the weighing module and the set value, maintaining a constant feeding quality per unit time.

Weighing and dosing system adds a certain amount of raw material from raw material tank to continuous mixing tank, according to different requirements of dye color, a certain amount of pigment (containing blue, red and yellow primary colors) from three reaction tanks is sent to continuous mixing tank, and then stirred for a certain period of time at a certain stirring speed in continuous mixing kettle and discharged through pipeline according to different dosing ranges. By calling the corresponding unit in the controller, the final realization of the material batch production. The process functions of mixing, resting and layering, and product discharge are realized by the mixing and discharge, and the related data in the units shown in dotted lines.

The Loop dosing system automatically adjusts the wind speed, circulating liquid flow rate and inlet liquid temperature according to the set operation parameters, collects the parameters of inlet and outlet liquid temperature, wind speed, atmospheric pressure, circulating liquid flow rate, wind resistance and liquid resistance, and sends them to the upper computer. The upper computer reads the data sent by each on-site measurement and control unit and calculates the liquid-side heat dissipation and air-side heat absorption according to the corresponding formulas specified in the standard. Usually chemical and physical changes occur in the dosage process, which can be composed of a number of simple tasks for the control of weighing. The process unit includes all production operations and auxiliary operations in batch production, which are processed in accordance with the order and operating parameters specified in the formula, guaranteeing the control of the dosage process without changes in quality.

The positive pressure batching system mainly uses pneumatic conveying to transfer powder materials from one place to another. Depending on the direction and force of the airflow, in the positive pressure conveying system, compressed air or other gases (generated by specific air supply equipment such as blowers or compressors) are introduced into the storage bins or containers containing the powder materials. These gases are then mixed with the powder materials under pressure, and under the pressure-driven force, they are transported through the ash conveying pipes to the designated location.
