Mixing system is the ideal batching equipment for continuous batching and measurement of bulk materials, which can be used for metering and feeding and can be combined with multiple units for automatic batching, which can form intelligent and programmed production management, high-performance intelligent weighing instruments, instruments and frequency conversion governor control screw conveyor speed to form closed-loop control. The built-in intelligent software regulator of the weighing instrument can set high, medium and low feed levels to ensure the accuracy of the ingredients. Three sets of output signals are used to control the frequency converter, and then control the feed speed of the screw Feeder, so as to achieve the purpose of accurate batching. The intelligent weighing instrument can set the feed amount manually, or set the ratio through the two-way communication between the computer and the instrument.

Communicate with PLC through serial port, and reflect the running status of loading, batching, feeding and related equipment in the form of dynamic screen according to the actual process of batching process. When there is an over-limit fault during operation,  will appear Chinese alarm, and start the alarm (sound and light), or stop the machine, or change the warehouse,  can make control status analysis according to the running data. The dynamic batching process of the system is reflected by different color histogram. According to the operation data, the industrial computer can assign the ratio or the feeding amount, and truly reflect the state of the dosing. In addition, the industrial computer is installed with the Batching system developed by Yuke Company. The dosing system also has other functions, such as class report, daily report, monthly report, annual report and so on. It provides convenience for management.

Pneumatic ash removal in electric power industry is a method of conveying fly ash in pipelines with air as carrier and pressure equipment (positive or negative pressure). The whole pneumatic conveying system is very simple. In operation, only the compressed air source, feeding device, conveying pipe and receiver with gas-material separation function can be automatically controlled through the system, and can continuously monitor the material delivery volume and monitor the input and output of the plant. The main components are level meter and pneumatic actuator, electric airlock, material conveying equipment, dry ash concentration equipment, dust removal equipment, air source equipment, air drying device, ash removal pipeline, bottom storage equipment, etc.

In the initial state of the bin pump, all valves are closed. In the feeding process, all valves are closed. The balance valve is opened first, so that air can be discharged from the bin pump at the same time. After the feed valve in the balance valve is opened, the discharge valve on the pipeline is closed to prevent air from being sucked into the ash hopper. When the bin pump shows that the material in the pump is full (the level meter is covered) or reaches the time set by the designer, the material falls into the bin pump under the natural action of gravity, and the feed valve and the balance valve are closed. This process requires a short delay, that is, the time for the valve to close after the feed valve and the balance valve are closed. When the pressurization reaches the set time or value, the exhaust valve is opened, and the compressed gas is transported to the ash warehouse through the pipeline. After the material reaches the ash warehouse, the transportation link of the bin pump is over, the pressure in the pipeline is reduced to a specific lower limit, and the intake valve is closed. After a period of delay, the residual pressure in the pump is discharged and the discharge valve is closed. Prepare to wait for the next cycle.
