Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, and more specifically, to a screw air compressor which is convenient for replacing filter membranes. Background Art

[0002] The screw air compressor is an oil-injected single-stage twin-screw compressor, which is divided into single-screw air compressor and twin-screw air compressor. It adopts high-efficiency pulley transmission to drive the main engine to rotate for air compression, and cools the compressed air in the main engine by oil injection. The air and oil mixed gas discharged by the main engine is separated through coarse and fine separation to separate the oil in the compressed air, and finally obtain clean compressed air. The screw air compressor has excellent reliability performance. Its biggest advantages are small vibration, low noise, easy operation, few wearing parts and high operating efficiency.

[0003] However, there are various types of air compressors in the prior art. For example, utility model patent CN220470217U relates to a screw air compressor that is convenient for replacing filter membranes. The utility model is provided with an electromagnet, a magnetic plate, a telescopic column, a spring, a movable plate, a limit rod and a limit hole. When replacing the filter membrane, the electromagnet is energized to drive the movable plate to move through the adsorption of the magnetic plate, thereby separating the limit rod from the limit hole, releasing the fixation of the filter membrane, and cutting off the power to the electromagnet. The telescopic column and the resilience of the spring can automatically reset the components. This method not only has a simple operation process, but also can quickly replace the filter membrane.

[0004] Although the screw air compressor is convenient for replacing the air intake filter membrane, the air compressor generates a large amount of heat during operation. Although it can take in air, it lacks heat dissipation and cooling function, and the heat dissipation effect is poor, so that the body is in a high temperature environment for a long time, affecting the service life of the air compressor. In order to avoid this phenomenon, it is very necessary to design a screw air compressor that is easy to replace the filter membrane. Utility Model Content

The present invention provides the following embodiments.

[0027] like Figure 1 , Figure 2 as well as Figure 3 As shown, it is a schematic diagram of the structure of the screw air compressor which is convenient for replacing the filter membrane in this embodiment. In this embodiment, the screw air compressor is often used for the circulation, compression and filtration of the refrigerant. Refrigeration equipment such as air conditioners and heat pumps all need to use screw compressors for air circulation and refrigeration. The air compressor includes an air compressor case 1, and the inner wall of the air compressor case 1 is fixedly connected with a partition plate 2. The upper surface of the partition plate 2 is installed with a screw air compressor body 19. The top of the partition plate 2 is penetrated by a mounting groove 3. The interior of the mounting groove 3 is installed with a cooling pipe 4 through a fixing member. One end of the cooling pipe 4 is connected to a water inlet pipe 5.
