Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an air compressor intake silencer structure with adjustable flow rate. Background Technology

[0002] As we all know, air compressors are widely used in people's production and daily life. When the air compressor is working, the high-pressure gas flows at high speed in the pipeline and rubs against the pipeline wall, which will generate a lot of noise. In order to reduce this noise, the most common practice is to install a silencer on the air compressor.

[0003] In a typical air compressor's silencing structure, sound-absorbing cotton and sound-absorbing plates are directly installed on the inner wall of the housing for noise reduction, with airflow passing directly through the housing. However, the airflow of a conventional air compressor's silencing housing structure is generally fixed and cannot be adjusted; its noise reduction effect is also fixed. Therefore, an intake silencing housing structure with adjustable flow rate is needed to achieve the best noise reduction effect for the air compressor intake. Utility Model Content

The arc-shaped guide plate is positioned on the back of the regulating door, and the regulating door is driven to rotate around the regulating shaft by driving the arc-shaped guide plate. The arc-shaped guide plate has a waist-shaped guide groove and passes through a guide hole at the top of the air guide shroud. The locking plate has an L-shaped structure and there is a pair of them. The locking plates are symmetrically positioned at the edge of the outer surface of the guide hole at the top of the air guide shroud, and bolt holes are provided on the locking plates. The locking bolt passes through the bolt hole on the locking plate and is embedded in the waist-shaped guide groove of the arc-shaped guide plate. By tightening the nut with the locking bolt, the locking plate clamps the arc-shaped guide plate, thereby controlling the opening and closing angle of the door.

[0006] Furthermore, the silencing enclosure includes a frame and sealing plates; the frame has a cuboid structure and is formed by welding several square tubes; the sealing plates are fixedly connected to the six sides of the frame by rivets; the sealing plates include a top sealing plate, a bottom sealing plate, and side sealing plates, and the side sealing plates have four respectively connected to the front, back, left, and right sides of the frame.
