Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic conveying, in particular to an air intake device of a novel pneumatic conveying system. Background Art

[0002] Positive pressure sending tank is a common conveying equipment, which is mainly used to convey powder, granular, granular materials, etc. The working principle of positive pressure sending tank is to use compressed air to transport materials from one place to another.

[0003] The positive pressure sending tank is mainly composed of a tank body, a pneumatic valve, a compressed air system, a conveying pipeline, etc. When materials need to be transported, the materials are first loaded into the tank body, and then the compressed air is controlled to enter the tank body through the pneumatic valve to form a certain pressure inside the tank body. When the pressure reaches a certain value, the pneumatic valve will automatically close, and the material will be pushed into the conveying pipeline by the compressed air, thereby realizing the material transportation. The working principle of the positive pressure sending tank can be simply summarized as "compressed air pushes materials". In this process, compressed air plays a key role. Compressed air can provide enough pressure to push the material to the target location. At the same time, compressed air can also play a role in cleaning the conveying pipeline to prevent the material from clogging the pipeline during the conveying process. The existing air intake device directly enters the air pipe from the top, and completes the pneumatic conveying of materials by increasing the gas pressure.

[0004] The existing air intake device enters the air pipe from the top and then completes the pneumatic conveying of materials. In material conveying, there are the following disadvantages:

[0005] The gas pressure needs to be increased to ensure smooth material transportation, which will increase the pressure on the tank wall when the gas pressure inside the tank increases;

[0006] If the material is agglomerated or bridging or is sticky, it will increase the difficulty of smooth material transportation and easily block the pipeline during transportation;

[0007] When materials are being transported, they will stick to the wall, making the transportation of materials not smooth and increasing the difficulty of material transportation. Utility Model Content
