[0002] An air compressor is a device that converts the mechanical energy of a prime mover into gas pressure energy. It increases the pressure of the gas by compressing the air, thereby providing a power source for various pneumatic equipment and systems. Using two-stage compression can reduce the compression ratio of each stage and reduce energy loss during the compression process, thereby improving energy utilization efficiency and achieving energy saving effects.

[0003] In the existing technology, some of the methods use fans to accelerate air flow and promote heat exchange, thereby taking away the heat generated by the compressor, while the filter plate can block the entry of dust and impurities. However, after using the filter plate for filtering for a long time, dust and impurities will continue to accumulate, gradually clogging the pores of the filter plate, reducing the ventilation area and the air circulation volume, so that the fan needs to consume more energy to drive the air flow, which increases energy consumption. Therefore, in response to the above shortcomings, a new energy-saving two-stage screw air compressor is proposed. Utility Model Content

[0030] Reference Figure 2 、 Figure 5 and Figure 6 The right side of the screw 4 is fixedly connected with a connecting plate 21. This connecting plate 21 can ensure that the connection between the screw 4 and other components during the rotation process is more stable, effectively transmits power, and reduces vibration and energy loss caused by loose connections.

[0031] Working Principle: First, the drive motor 5 starts, and its power is transmitted to the transmission 6 through the drive end. The transmission 6 flexibly adjusts the power according to the actual working requirements, achieving an optimal match between speed and torque, and then stably transmits the power to gear 1 7. Gear 1 7 is meshed with the two gears 2 8 on the left side of the compressor 3, driving gear 2 8 to rotate. The left ends of the two rear screws 4 are respectively fixedly connected to the right ends of the two gears 2 8. The rotation of gear 2 8 drives the screws 4 to rotate precisely and in coordination inside the compressor 3, achieving an efficient gas compression process.

[0032] During the compression process, the water cooling assembly activates to cool compressor 3. Driven by water pump 11, the coolant in water tank 9 is accurately delivered via circulation pipe 12 to heat conducting fins 14 on the front side of compressor 3. Heat conducting fins 14 rapidly absorb the heat generated by compressor 3 and transfer it to the coolant flowing through them. After passing through heat conducting fins 14, the coolant returns to water tank 9 via circulation pipe 13. Multiple cooling fins 10 on the left side of water tank 9 rapidly dissipate heat from the tank 9 to the surrounding environment, significantly enhancing the heat dissipation efficiency of the tank 9.

[0033] To ensure the proper functioning of the cooling system, filter plate 15 effectively blocks impurities. When motor 17 is activated, it drives rotating rod 18. Blades 19 on the outside of rotating rod 18 generate a powerful airflow, enhancing heat dissipation. A cleaning brush 20 at the front of motor 17 promptly removes impurities from filter plate 15 as it rotates, ensuring its permeability and filtration effectiveness.

[0034] On the right side of the screw 4, the screw 4 drives the connecting plate 21 to rotate, and the connecting plate 21 is connected to the right side of the compressor 3. The multiple telescopic rods 22 on the right end of the connecting plate 21 are adjusted in length according to the pressure changes inside the compressor 3 and the relative displacement between the components to ensure the flexibility and reliability of the connection. The spring 23 plays an elastic role between the connecting plate 21 and the connecting ring 24, providing continuous pressure and buffering. The dynamic ring 25 on the right end of the connecting ring 24 cooperates with the static ring 26 on the left end of the right rotating shaft 27 inside the compressor 3 to achieve a sealing function, prevent gas leakage and lubricating oil seepage, and improve the working efficiency and performance stability of the compressor 3.
