Description

Technical Field

[0001] The present application relates to the technical field of compressors, and in particular to a four-piece screw compressor. Background Art

[0002] In modern industrial production, screw compressors, as key power equipment, are widely used in a variety of fields, including construction, metallurgy, chemicals, food, and medicine. Screw compressors, with their high efficiency, stability, and low noise, have become the mainstream choice in the air compression industry. With the continuous advancement of industrial technology, the performance requirements for compressors are also increasing. This is especially true in demanding industrial scenarios such as precision manufacturing and pharmaceutical production, which place increasingly stringent standards on compressed air purity and compressor operating efficiency. Therefore, the development of new, efficient, and reliable screw compressor technologies has become a pressing need for the current industry development.

[0003] Screw compressor technology has made significant progress, particularly in the four-screw air compressor, whose unique four-screw structure further enhances compressor efficiency and stability. During operation, as the gear reducer drives the main shaft and the two screw shafts to rotate in the same direction, the gap between the rotating and stationary screws gradually decreases, continuously compressing the gas. This structure not only simplifies the compressor's internal structure but also improves the continuity and stability of the compression process, reducing noise and vibration.

[0004] When traditional four-screw air compressors pressurize air and oil, the rotating friction of the drive shaft creates iron filings that continuously mix into the lubricating oil, causing the oil to degrade and become viscous. This not only increases the compressor's operating resistance and reduces compression efficiency, but can also cause abnormal wear of mechanical components and even cause the compressor to malfunction and shut down.

[0036] The drive assembly includes a follower gear 19 fixedly connected to one end of the compression screw 8, a driving gear 20 meshing with the follower gear 19 fixedly connected to one end of the base 1, and a drive motor 21 fixedly connected to one end of the base 1, and the output end of the drive motor 21 is fixedly connected to the driving gear 20;

[0037] Moreover, a ventilation hole 22 is provided at one end of the cross scraper 12;

[0038] In addition, one end of the separation box 10 is fixedly connected to a discharge pipe mouth 23 adapted to the arc filter plate 15, and a solenoid valve 24 is provided inside the discharge pipe mouth 23. The interior of the separation box 10 is rotatably connected to a screw dragon 25, and the screw dragon 25 is installed inside the arc filter plate 15. One side of the separation box 10 is fixedly connected to a discharge motor 26, and the output end of the discharge motor 26 is fixedly connected to the screw dragon 25.

[0039] During use, the air is first filtered by the air filter 6 and then introduced into the interior of the compression chamber 3 through the air inlet duct 5. At this time, the driving motor 21 is started to drive the driving gear 20 to engage with the follower gear 19, and the follower gear 19 drives the four compression screws 8 to rotate synchronously, so that the compression screws 8 push the air and oil through the compression chamber 3 into the interior of the exhaust duct 7, thereby completing the compression of the air. The compressed air is then introduced into the interior of the separation box 10 through the exhaust duct 7 and the air guide pipe 9;

[0040] At the same time, the air entering the separation box 10 collides with the arc-shaped magnetic plate 11, so that the metal debris in the air is adsorbed on the surface of the arc-shaped magnetic plate 11. At the same time, the compressed air is pumped into the refrigerator 16 through the air guide pipe 18 by starting the air pump 17 to be cooled and wait for later use. At the same time, the oil in the air flows to the inner part of the separation box 10 under the action of gravity, and the oil return pump 35 is started to re-introduce the oil into the compression chamber 3 for recycling.

[0041] When metal debris in the air is adsorbed on the inner side of the arc-shaped magnetic plate 11, the filter motor 14 is started to drive the ventilation hole 22 to rotate, and the ventilation hole 22 is driven to scrape the metal debris on the inner side of the arc-shaped magnetic plate 11, thereby pushing the metal debris adsorbed on the inner side of the arc-shaped magnetic plate 11 to move to one side of the isolation plate 13, and break away from the magnetic attraction of the arc-shaped magnetic plate 11, and then slide along one side of the isolation plate 13 to the inside of the arc-shaped filter plate 15. Then, when too much debris accumulates inside the arc-shaped filter plate 15, the solenoid valve 24 is opened to release the shielding of the discharge pipe mouth 23, and then the discharge motor 26 is started to drive the auger 25 to rotate, and push the debris inside the arc-shaped filter plate 15 through the discharge pipe mouth 23 to be discharged from the interior of the separation box 10, thereby facilitating the automatic filtering and cleaning of debris mixed in the oil, reducing the operating resistance of the compressor, and improving the compression efficiency.

[0042] Reference Figure 1 and Figure 3 、 Figure 5 The inner bottom of the separation box 10 is fixedly connected with a guide ramp 27, which is installed below the isolation plate 13.

[0043] During use, when air carries oil into the interior of the separation box 10, the oil is affected by gravity and passes through the arc filter plate 15, and flows and gathers toward one end of the inner bottom of the separation box 10 along the guiding direction of the guide ramp 27, thereby facilitating the use of the return oil pump 35 to circulate the oil into the interior of the compression chamber 3, effectively improving the practicality of the device.

[0044] Reference Figure 1 and Figure 3 、 Figure 5 , a filter cartridge 28 is fixedly connected to the inner top of the separation box 10, and the input end of the air guide pipe 18 is installed inside the filter cartridge 28;

[0045] One end of the filter cartridge 28 is rotatably connected to a mounting ring 29, and one end of the mounting ring 29 is symmetrically rotatably connected to a roller brush 30. A scrubbing motor 31 is fixedly connected to the top of the separation box 10. The output end of the scrubbing motor 31 passes through the separation box 10 and is fixedly connected to a scrubbing gear 32. One end of the mounting ring 29 is fixedly connected to a scrubbing gear ring 36 that meshes with the scrubbing gear 32.

[0046] Furthermore, one end of the filter cartridge 28 is fixedly connected to a transmission gear 33 , and one end of the roller brush 30 is fixedly connected to a transmission gear ring 34 meshing with the transmission gear 33 .

[0047] During use, when the air pump 17 is started to pump the air inside the separation box 10 through the air guide pipe 18, the oil in the air is filtered and intercepted by the filter cartridge 28. At the same time, the scrubbing motor 31 is started to drive the scrubbing gear 32 to engage with the scrubbing gear ring 36, thereby driving the mounting ring 29 to drive the roller brush 30 to rotate around the periphery of the filter cartridge 28 and scrub the oil adhered to the surface of the filter cartridge 28, thereby reducing the clogging of the filter cartridge 28.

[0048] As the roller brush 30 rotates around the periphery of the filter cartridge 28 , the roller brush 30 drives the transmission gear 33 to engage with the transmission gear ring 34 , and drives the roller brush 30 to rotate on its own, thereby effectively improving the cleaning efficiency of the roller brush 30 on the surface of the filter cartridge 28 .

[0049] The implementation principle of the four-piece screw compressor of this embodiment is as follows: first, the air is filtered by setting an air filter 6, and then introduced into the interior of the compression chamber 3 through the air inlet duct 5. At this time, the driving motor 21 is started to drive the driving gear 20 to engage with the follower gear 19, and the follower gear 19 drives the four compression screws 8 to rotate synchronously, so that the compression screws 8 push the air and oil through the compression chamber 3 into the interior of the exhaust duct 7, thereby completing the compression of the air. Then, the compressed air is introduced into the interior of the separation box 10 through the exhaust duct 7 and the air guide pipe 9;

[0050] At the same time, the air entering the separation box 10 collides with the arc-shaped magnetic plate 11, so that the metal debris in the air is adsorbed on the surface of the arc-shaped magnetic plate 11. At the same time, the compressed air is pumped into the refrigerator 16 through the air guide pipe 18 by starting the air pump 17 to be cooled and wait for later use. At the same time, the oil in the air flows to the inner part of the separation box 10 under the action of gravity, and the oil return pump 35 is started to re-introduce the oil into the compression chamber 3 for recycling.

[0051] When metal debris in the air is adsorbed on the inner side of the arc-shaped magnetic plate 11, the filter motor 14 is started to drive the ventilation hole 22 to rotate, and the ventilation hole 22 is driven to scrape the metal debris on the inner side of the arc-shaped magnetic plate 11, thereby pushing the metal debris adsorbed on the inner side of the arc-shaped magnetic plate 11 to move to one side of the isolation plate 13, and break away from the magnetic attraction of the arc-shaped magnetic plate 11, and then slide along one side of the isolation plate 13 to the inside of the arc-shaped filter plate 15. Then, when too much debris accumulates inside the arc-shaped filter plate 15, the electromagnetic valve 24 is opened to release the shielding of the discharge pipe 23, and then the discharge motor 26 is started to drive the auger 25 to rotate, and the debris inside the arc-shaped filter plate 15 is pushed through the discharge pipe 23 to be discharged from the interior of the separation box 10;

[0052] Then, when the vacuum pump 17 is started to draw the air inside the separation box 10 through the air guide pipe 18, the oil in the air is filtered and intercepted by setting the filter cartridge 28. At the same time, by starting the brushing motor 31, the brushing gear 32 is driven to engage with the brushing gear ring 36, thereby driving the mounting ring 29 to drive the roller brush 30 to rotate around the periphery of the filter cartridge 28 and brush the oil adhered to the surface of the filter cartridge 28, thereby reducing the blockage of the filter cartridge 28 surface.
