Description

Technical Field

[0001] The utility model relates to the technical field of air compressor exhaust, in particular to a circulating exhaust guide mechanism for an air compressor. Background Art

[0002] Air compressors can be divided into three categories according to their working principles: volumetric, dynamic (speed or turbine), and thermal compressors. The compressor is directly driven by an electric motor, which causes the crankshaft to rotate, drives the connecting rod to make the piston reciprocate, and causes the cylinder volume to change. When the air compressor is working in industry, it can compress the air in the air compressor, thereby generating a relatively high amount of heat. When the heat is generated, the exhaust pipe will be used to guide the exhaust, so that the hot air is discharged to the outside. The utility model with the publication number CN215719346U discloses a circulating exhaust guide mechanism for an air compressor, including a circulating purification box, a bottom plate is fixedly installed at the bottom of the circulating purification box, an air connection pipe port is fixedly connected to the bottom of one side of the circulating purification box, a disassembly sleeve is detachably installed on one side of the outer surface of the air connection pipe port, an exhaust pipe is fixedly connected to the middle part of the disassembly sleeve, a clamping plate is fixedly installed on the upper and lower surfaces of the air connection pipe port, and disassembly bolts are detachably installed on the upper and lower surfaces of the disassembly sleeve. However, when the utility model is used, the hot air discharged from the air compressor is directly cooled and filtered, which will cause the heat loss of the hot air, so that it cannot be effectively utilized, resulting in poor resource recycling effect. Therefore, it is very necessary to design a circulating exhaust guide mechanism for an air compressor that is highly practical and can utilize heat. Utility Model Content

[0010] According to the above technical solution, a water level mark is provided at the front end of the cooling chamber.

[0011] Compared with the prior art, the beneficial effect achieved by the utility model is as follows: the utility model is provided with an air inlet pipe, which is connected to the air outlet of the air compressor.

When the cooling water becomes hot, it will drive the internal inert air to heat up, and then the inert air will expand, push the sealing piston plate to move upward, and drive the cleaning brush to brush and clean the activated carbon filter. When the air compressor stops exhausting air, the temperature in the filter chamber drops, the sealing piston plate moves downward, and the cleaning brush moves downward together, brushing the activated carbon filter again to prevent large particles of impurities from clogging the activated carbon filter, extending the service life of the activated carbon filter, and realizing the secondary recycling of hot air heat.
