Description

Technical Field

[0001] This application relates to the field of air compressors, and particularly to an air compressor exhaust device. Background Art

[0002] An air compressor, also known as a compressor, is a device that converts the mechanical energy of a prime mover (usually an electric motor) into gas pressure energy and is a pneumatic pressure generating device for compressed air. An air compressor includes multiple parts such as an intake system, an electric control system, a power system, a pipeline system, a separation system, a cooling system, a sound insulation system, and a storage tank. These parts work together to ensure the normal operation and efficient work of the air compressor.

[0003] The storage tank not only provides a buffer and storage space for compressed air but also plays a role in cooling. When compressed air passes through the storage tank, the high-speed air flow impacts the tank wall to generate confluence, causing the temperature to drop rapidly, thereby liquefying a large amount of water vapor to form condensate. The storage tank contains a certain amount of water, which will cause the gas discharged from the air compressor to have too much water content.

[0004] The water content in the gas discharged from the air compressor will bring various harms. In the spraying process, if there is water mist in the compressed air, it will seriously affect the adhesion effect of the paint on the workpiece, resulting in coating failure or unqualified coating quality; many industries have strict requirements on the quality of compressed air. If the compressed air contains water, it will directly affect the quality of the final product; in some cases, the water-containing compressed air may cause safety hazards such as short circuits or fires in electrical equipment. These harms not only affect the normal operation of the equipment but may also have a serious impact on the production process and product quality. Utility Model Content
