Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a pressure balancing device for pneumatic conveying of powdered materials. Background Art

[0002] The raw materials required in industry mainly include powders, granules, solutions and dispersions. Monomers and prepolymers are used for some molding, while powders and granules are more widely used. However, powder materials are more troublesome to transport. If they are directly transported, it will take too much manpower and material resources. Therefore, pneumatic conveying devices are generally used to transport materials. When this device is used, compressed gas needs to be input into the material tank storing the material to be transported to mix the compressed gas and the material. The mixed compressed gas and material enter the silo through the pipeline, and the compressed gas is discharged into the air through the dust removal device. The material is deposited in the silo to achieve the separation of the material and the compressed gas. However, this device simply transports materials through compressed air and cannot automatically adjust the pressure in the conveying pipeline. When the pressure in the conveying pipeline is too high, it will lead to high energy consumption and equipment wear, which is not conducive to long-term production. When the pressure in the conveying pipeline is too low, the amount of conveyed material will be reduced, which will take too long and affect production efficiency.

[0003] Based on this, a pressure balancing device for pneumatic conveying of powdered materials is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

During this process, it is necessary to start the control valve 108 to open the exhaust pipe 107 and discharge the excess air in the sealing box 106. When the powdered material in the sealing box 106 is full, the first motor 103 is started to rotate the sealing plate 105 to close the channel inside the connecting block 102, so that a sealing structure is formed inside the sealing box 106 to prevent the gas from blowing up the material during material transportation.

[0028] A discharge port 109 is provided at the lower end of the sealing box 106, and a mounting block 200 is provided at the lower end of the sealing box 106.

When the powder material enters the collecting box 400, the material will fall into the collecting box 400, and the gas will be discharged from the exhaust channel 403. During the discharge process, the gas will drive the powder material to float. At this time, the filter sleeve 404 can filter the discharged gas to prevent the material from being discharged. After the material transportation is completed, the stop valve 402 can be started to discharge the material from the discharge pipe 401.
