Description

Technical Field

[0001] The utility model relates to the technical field of sand and dust test devices, in particular to a pneumatic material conveying component and a sand and dust test device. Background Art

[0002] The sand and dust test device is a sand and dust test chamber. The scientific name of the sand and dust test chamber is "sand and dust test chamber". It simulates the destructiveness of natural wind and sand climate to products. It is suitable for testing the shell sealing performance of products. It is mainly used for the two levels of IP5X and IP6X tests specified in the shell protection level standard. The equipment has a vertically circulating airflow with dust. The test dust can be recycled. The entire air duct is made of imported high-grade stainless steel plates. The bottom of the air duct is connected to the conical hopper interface. The fan inlet and outlet are directly connected to the air duct. Then, the diffuser on the top of the studio is connected to the studio body at an appropriate position to form an "O"-shaped closed vertical dust blowing circulation system, so that the airflow can flow smoothly and the dust is dispersed evenly to the maximum extent. A single high-power, low-noise centrifugal fan is used, and the wind speed is adjusted with a variable frequency speed regulator according to the test needs;

[0003] The test dust will be circulated and transported using a pneumatic material conveyor to achieve continuous reciprocating testing. The pneumatic material conveyor uses pressurized air as the conveying medium to transport materials crushed to a certain particle size along the pipeline for mechanized operations such as bulk loading and bulk transportation.

[0004] Conventional pneumatic material conveyors use a vibration motor to move the material in the hopper toward the bottom, but the vibration motor produces a lot of noise during this process. In addition, during the process of convergence, the material may be blocked, thus affecting the material conveying.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a pneumatic material conveying component and a dust test device are proposed. Utility Model Content

[0025] The device frame group 1 includes a shock-absorbing seat 101, a stable seat 102 and a support beam 103.
