Description

Technical Field

[0001] This invention relates to the field of air compressor technology, specifically to a screw air compressor with built-in dehumidification function. Background Technology

[0002] An air compressor is a device used to compress gases. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane, or rotary screw type. Air compressors can be classified into three main categories according to their working principle: positive displacement, dynamic (speed or turbine), and thermal compressors. Screw air compressors, with their advantages of high efficiency, high performance, maintenance-free operation, and high reliability, provide high-quality compressed air to various industries.

[0003] For example, Chinese utility model patent CN215805165U discloses a silent permanent magnet variable frequency screw air compressor, belonging to the field of screw air compressor technology. It includes a silent permanent magnet variable frequency screw air compressor housing, which comprises a silent chamber, a sound transmission chamber, a permanent magnet variable frequency motor, a screw air compressor head, an air outlet pipe, and an air outlet. The sound transmission chamber is connected to the bottom of the silent permanent magnet variable frequency screw air compressor housing, and the silent chamber is connected to the sound transmission chamber. At the bottom, a screw air compressor head and a permanent magnet variable frequency motor connected to the screw air compressor head are provided on the sound transmission chamber. The top of the screw air compressor head is connected to one side of the air outlet pipe, and the other side of the air outlet pipe is connected to the air outlet. The air outlet pipe and the air outlet are covered with a first sound insulation cover. The permanent magnet variable frequency motor is covered with a second sound insulation cover. The inside of the silent permanent magnet variable frequency screw air compressor housing is provided with a sound-absorbing layer. This utility model has the advantages of reducing noise and reducing the vibration caused by noise.

The equipment can rotate the moving rod 11 by turning the rotating block 12, so that the locking block 13 disengages from the locking groove 1401 and engages in the fixed groove 303, no longer limiting the positioning block 14, and the cleaning brush 16 can be removed for easy cleaning.
