The mixing system is composed of unpacking bucket, powder tank car, bag filter, induced draft fan, etc. The unpacking bucket adopts a double-side feeding structure, which can be fed in two directions at the same time. The unpacking hopper automatically adds the powder from the powder tank to the powder pressure conveying tank. The bag filter can effectively avoid powder flying and improve the working environment.

The storage system is composed of large storage bin, bag filter, induced draft fan, balance valve, screw feeding device, storage bucket, etc. The powder sent by the conveying system is sent to different large storage bins for storage according to the model. When conveying powder, the induced draft fan automatically opens and controls the powder flying through the bag filter, the balance valve automatically opens to balance the pressure in the large storage bin, the screw feeding device at the bottom of the large storage bin will send the powder to the storage hopper for further transmission to the Weighing system, and the balance valve will automatically close after the delivery. Three material levels of high, middle and low are designed for the large storage bin. When the material level is low, it must be added, and when it is high, it must be stopped.

The conveying system is composed of air source, pressure conveying tank, distributing valve and double pipe conveying pipeline. After the powder is sent to the pressure conveying tank through the unpacking bucket, compressed air is sent to the tank to blow the powder up, so that the powder is in a floating state. When the pressure in the pressure conveying tank reaches a certain value, maintain the pressure for 2 to 3 minutes, and then open the discharge valve, and open the compressed air valve on the conveying pipe, and the powder is transported along the conveying pipe to the storage tank under the action of compressed air. In order to ensure the constant conveying pressure, compressed air with the same pressure will be added to the conveying pipeline at every certain interval on the conveying pipe to ensure the conveying speed. The conveying pipe is a double pipe structure, and the inner pipe is a flexible rubber material pipe, which can resist powder erosion and reduce the crushing rate of powder particles during high-speed conveying. The outer tube is made of hard aluminum alloy material, which can withstand certain pressure.

The weighing system is composed of day hopper, bag filter, balance valve, feed screw, central bag filter, recovery screw, powder Electronic scale, powder check scale and discharge fork. The powder is transported to the daily hopper through the conveying system to wait for the weighing. When the weighing is started, the feeding valve at the bottom of the daily hopper opens, and the feeding spiral moves to transport the powder powder to the powder hopper scale (when transporting the powder, the central bag filter adsorbed the flying powder to the filter bag of the bag filter to prevent the flying pollution of the powder). After the powder weighing is completed, the disc valve of the powder hopper scale is opened, and the powder is unloaded to the powder checking scale along the feeding pipe to check the accuracy of the weighing. After the completion of the check, the discharge valve of the powder check scale is opened, and the powder is sent to the batching warehouse of the batching machine through the pipeline and the discharge fork. The internal spray of anti-stick and anti-corrosion chemical raw material paint can not only make the powder smooth, prevent the powder from adhering to the inner wall, but also effectively prevent the corrosion of the powder to the storage bucket and extend the service life of the storage bucket.
