Description

Technical Field

[0001] The utility model relates to the field of high-pressure fans, in particular to a corrosion-resistant high-pressure fan. Background Art

[0002] A high-pressure fan is one that, under design conditions, operates at a pressure of 30kPa to 200kPa or a compression ratio of e = 1.3 to 3. Currently, the industry generally classifies gas ring vacuum pumps as high-pressure fans. High-pressure fans, also called high-pressure blowers, are distinguished from conventional centrifugal blowers. High-pressure fans generate noise during operation, and silencers are typically installed at the gas inlet and outlet at the rear end of the fan to absorb and eliminate the noise generated by the inlet and outlet air.

[0003] Since the air inlet absorbs external air, although a dust-proof net is installed, long-term use will cause fine dust to still adhere to the surface of the sound-absorbing material, reducing the sound-absorbing effect. Therefore, the sound-absorbing material needs to be cleaned or replaced regularly.

[0004] In the existing technology, when replacing the silencer material, the entire silencer pipe needs to be disassembled, which requires the silencer pipe, the fan air inlet and the connecting flange to be disassembled, which is time-consuming and labor-intensive. Utility Model Content

[0008] Preferably, a hole adapted to the silencer net and corresponding to the air inlet of the pump body is opened in the middle of the front fixing plate, and a hole adapted to the silencer cotton is opened in the middle of the rear fixing plate.

[0009] Preferably, the silencer net and the silencer cotton are both hollow cylindrical structures.

[0010] Preferably, the guide plate has a gradient structure, the rear end of the guide plate is flush with the hole of the rear fixing plate, and the front end of the guide plate abuts against the front fixing plate and is separated from the fixing plate by a gap.
