A centralized feeding system is a production equipment used in industry to automatically and accurately process different powders or liquid materials in a certain proportion. It usually consists of Weighing modules, weighing instruments, PLC systems, and upper computers, including storage, conveying, weighing and batching, dust removal, material mixing, and other equipment for raw materials; The batching method can be reasonably selected based on industry characteristics, production process requirements, and specific material characteristics, such as "incremental" or "subtractive" weighing methods, with multiple working modes including single bucket single material, single bucket multiple material, and multi bucket multiple material. The feeding system is a flexible and variable production control system software developed by combining industrial control technology and Internet of Things technology. It integrates various control points of the production process into one control software, allowing customers to control the entire factory production process from the central control room. Truly achieving highly integrated, automated, and unmanned efficient workshops. Central control data acquisition and control system: comprehensive observation and centralized management. Using PLC/DCS as the core control, the computer system is responsible for formula calculation, personnel management, data collection, query and printing, etc. The central control computer monitors and controls the on-site production situation, reflecting the real-time operation of each production unit.

The weighing and feeding system includes a feeding device for feeding, a storage device set outside the dissolution device, and an electronic weighing scale set in the storage device. The feeding device will be transported to the storage device, and the explosion-proof weighing scale will complete the weighing of the predetermined weight. After weighing, it will enter the dissolution device from the storage device for dissolution treatment. The storage device is set at the top of the dissolution device, and the open end of the storage device is equipped with a valve. After a predetermined weight is conveyed in the storage device, the valve opens and falls from the storage device into the dissolution device. The weighing scale is assembled between the storage device and the dissolution device, and the valve is an electric ball valve, pneumatic ball valve, or electric spiral discharge valve. The electric spiral discharge valve includes a rotating shaft, which is set at the outlet end of the storage device to block the outlet end of the storage device. The rotating shaft is equipped with a storage tank for storage. When a predetermined weight is conveyed in the storage device, the rotating shaft rotates to a predetermined position and falls to the dissolution device due to its own gravity for unloading. After unloading, the rotating shaft rotates back to its original position. The feeding device includes a negative pressure generating part, which is connected and connected to the storage device through a connecting pipe. The storage device is connected to the storage device through a conveying pipe. When the negative pressure generating part works, negative pressure is generated inside the storage device, which is then conveyed to the storage device through the conveying pipe. The feeding device includes a control system, which is electrically connected to the weighing scale, negative pressure generating unit, and valve. The connecting pipeline is connected to the feeding device through a quick release structure. The quick release structure includes a connection structure that matches the plug and slot, and a threaded connection structure.

Process flow of automated Batching system

1: From the silo to the batching tank, and then from the reaction kettle to the mixing tank, the weight is measured by the weighing module, and the speed of the frequency converter is adjusted according to the actual required flow rate to achieve normal feeding.

2: After being measured by the punch flow meter, it enters the feed box of the spiral pneumatic conveying pump and is pushed forward through the feeding mechanism.

3: Entering the mixing chamber and being vaporized by the air outlet of the fan, it is then sent into the conveying pipeline.

In the above process, the frequency converter plays the role of quantitative and steady flow. The flowmeter can not only accurately measure the flow but also detect whether the coal powder in the system is short of material. The screw conveying pump plays the role of both air locking and material conveying.
