In addition to meeting the performance indicators required by the weighing instrument, the selection of weighing sensors should try to use sensors with consistent output sensitivity and input impedance, and connect them correctly in the wiring compensation box. The wiring compensation box shall be installed near the weighing instrument in the metering room.

The weighing module, pressure transmitter, level gauge, position switch on the pneumatic valve, air source pressure gauge and other components in the ton bag automatic mixer are used to detect and monitor the working conditions. For multi-bin conveying, the three-way valve can be controlled by the touch screen to make bin selection judgments. When the multi-bin pump conveys a single bin, to prevent material backflow, a shut-off valve needs to be installed above the receiving bin.

The Weighing fully automatic mixer adopts an industrial computer with high protection level as the main control computer of the system, and a special filter screen is used in the computer ventilation and heat dissipation system, which can be cleaned or replaced regularly and can effectively remove the influence of dust in the air on the equipment. The weighing system is input into the computer system through the man-machine interface or computer network, and the computer control system automatically calculates the supply ratio of each raw material according to the detection data and the process formula, and then the PLC control system synthesizes the supply speed of each raw material supply system to accurately and continuously complete the raw material ratio according to the process sequence.

The Positive pressure weighing mixer achieves the requirement of batcher control precision and reduces the cost as much as possible through the dosage ratio of each raw material. According to the difference of each batch of materials and arbitrary change, optimize the calculation table input database using the development of visual man-machine interface, read the calculation data and display in the interface, visually create the database application program, make the application of the database more convenient and flexible, while supporting the application of network environment.

The Fan weighing mixer installs a module at the bottom of the silo, and ensures the normal operation of the whole system through the precise control of the electrical program. The control objects in the pneumatic conveying of positive pressure pulse material and acid are the exhaust valve, feed valve, discharge valve, pulse gas knife valve and inlet valve in the silo. The control mode is controlled by Siemens programmable controller, and the solenoid valves and motors are controlled by the operation of Proface touch screen, contactors and intermediate relays, which is convenient for debugging and maintenance.

The Pulse Width automatic mixer is equipped with an activation hopper and gasification at the bottom of the storage bin. When discharging, the activation hopper vibrates continuously and the gasification purging ensures the smooth falling of materials, and the eccentric vibration module can be used to adjust the vibration amplitude to improve the efficiency and gasification purging frequency. When conveying materials, the conveying capacity and conveying efficiency can be changed by adjusting the air time and material time of the air knife valve, which is helpful to meet some links with high requirements for crushing rate. The pulse interval and pulse width can also be adjusted to avoid dust leakage in the storage bin during transportation.

After the Broken mixer reads it through PLC communication, the corresponding operation is performed. At the same time, PLC moves the monitoring signals to be collected by the touch screen into the communication storage area, and the touch screen can be monitored on the PC by reading the data, and the whole system is connected in series through pressure elements and weighing modules, so as to realize industrial automation, improve transportation efficiency and effectively prevent dust leakage, providing good environmental protection for field workers.

The Three-dimensional weighing mixer is composed of some pneumatic and mechanical mechanisms, such as positioning mechanism, front silo supporting mechanism and conveying mechanism, etc. The cylinder is equipped with an in-place detection device. The control system consists of operation panel, plc system, weighing module, LCD screen, operation keyboard, process control point and upper computer. The weighing system ensures the accurate delivery of materials, reads the data of electronic scales, and displays the data in real time on the special plane display screen. At the same time, the data are sent to the upper computer to form a table for the batch data such as materials and density on the production line and analyze and process it.

The metering mixer consists of industrial computer, PLC, industrial weighing control terminal (LYNX), frequency converter, vibration motor, screw feeder, weighing module and so on. The industrial computer provides man-machine interactive interface, and completes the functions of controlling information input, data management, data display, storage, statistics and reports. All the control work is completed by PLC. During the system operation, PLC communicates with the upper computer in real time, so as to ensure the consistency between the data displayed on the interface and the actual data on site. The operating commands and setting parameters issued by the operator on the upper computer can be sent to the PLC for execution in real time.
