Problems solved by technology

[0002] In the field of pneumatic conveying, the current technology mostly uses a material-sealed pump to enter the material, and the material is started and accelerated with a suitable material-gas ratio. During the operation of this device, the movement between the moving parts and the body will be very fast. Wear and tear, the seal will also fail quickly, and it is easy to cause air leakage. Air leakage will bring dust, resulting in a bad working environment and affecting the physical and mental health of the operator; inside the material-sealed pump, the shape and volume of the container, the size of the nozzle The size design is not ideal, and leftover materials will be generated, and the leftover materials will accumulate more and more, and they must be cleaned up after a period of work, otherwise it will affect the efficiency of use, and even the entire system will not work
Due to the above defects, the application field of pneumatic conveying is limited, so a new type of device is urgently needed to replace this product
