Description

Technical Field

[0001] This utility model relates to the field of screw air compressors, and more particularly to a low-noise screw air compressor. Background Technology

[0002] Screw air compressors, as highly efficient gas compression equipment, are widely used in many fields such as industrial manufacturing, mining, construction, and pharmaceuticals due to their compact structure, stable operation, and large air output. In industrial production processes, air compressors provide a continuous and stable supply of compressed air for various pneumatic tools and equipment, making them one of the key pieces of equipment ensuring normal production operation.

[0003] However, during the operation of a screw air compressor, the high-speed rotation of the internal screw rotor, the operation of the motor, and airflow disturbances all generate significant noise. This noise can not only damage the hearing of operators, affecting their health and work efficiency, but also cause noise pollution to the surrounding environment, failing to meet the requirements of modern industrial production for green, environmentally friendly, and low-noise operation.

[0004] Meanwhile, if the air compressor draws in dust, impurities, moisture, etc. during the intake process, these substances will accelerate the wear of parts such as the screw rotor and bearings after entering the air compressor, shorten the service life of the equipment, and even affect the quality of compressed air, which will have an adverse effect on subsequent production processes and product quality.

[0005] Currently, while existing screw air compressors on the market have implemented some measures in terms of noise reduction and air filtration—for example, some equipment may be equipped with simple soundproof covers or filtration devices—these measures often have limitations. Regarding noise reduction, traditional soundproofing structures are mostly single-layer panels, offering limited sound insulation. Furthermore, the disassembly and installation of soundproof covers during equipment maintenance are cumbersome, impacting work efficiency. As for air filtration, existing filtration devices have low filtration accuracy, are inconvenient to replace filter components, and struggle to effectively remove fine impurities and moisture from the air, failing to meet the demands of high-precision production scenarios.

[0006] Therefore, those skilled in the art are dedicated to developing a low-noise screw air compressor. Utility Model Content

[0007] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is to reduce the noise generated during the operation of the equipment, reduce the impact on operators and the surrounding environment; efficiently remove dust, impurities and other contaminants from the intake air, extend the service life of the equipment, ensure the quality of compressed air, and facilitate the inspection and maintenance of internal components.

[0008] To achieve the above objectives, this utility model provides a low-noise screw air compressor, including a base plate. The air compressor body is mounted on the upper end of the base plate. Two side plates are fixedly connected to the upper end of the base plate, and two slide rails are fixedly connected to the upper end of the base plate. A cover plate is slidably connected to both slide rails. The cover plate and the side plates are both double-layer composite boards. Sound insulation cotton is provided on the inner wall of the cover plate and on the adjacent sides of the two side plates. Heat dissipation holes are provided on both side plates, and limiting components are provided on the opposite sides of the two side plates. The limiting components are used to limit the cover plate.

[0009] In a preferred embodiment of the present invention, the limiting component includes two rotating shafts rotatably connected to the side plate, a rotating plate fixedly connected to each of the two rotating shafts, a guide rod rotatably connected through each of the two rotating plates, a pressure block fixedly connected to the side of each of the two guide rods near the side plate, and the two guide rods and the corresponding rotating plates being elastically connected by springs.

[0010] In another preferred embodiment of the present invention, each of the two side plates is provided with two sets of positioning components. The positioning components include through holes provided on the rotating shaft. A fixing block is fixedly connected to the side plate. The fixing block is provided with a round hole. A positioning pin is slidably connected through the through hole. The positioning pin passes through the round hole.

[0011] In another preferred embodiment of the present invention, each of the positioning pins is provided with a threaded layer, and each of the threaded layers is threaded with a nut.

[0012] In another preferred embodiment of the present invention, a rubber sealing strip is fixedly connected to the outer side of each of the two side plates, and the rubber sealing strip is U-shaped.

[0013] In another preferred embodiment of the present invention, the upper end of the cover plate is connected to a vertical pipe, the upper end of the vertical pipe is fixedly connected to a filter box, the upper end of the vertical pipe is connected to the top space of the filter box, the filter box is provided with a filter assembly, the filter assembly includes a magnetic plate, the lower end of the magnetic plate is fixedly connected to a filter cylinder, and an air inlet pipe is fixedly connected through the magnetic plate.

[0014] In another preferred embodiment of the present invention, a centrifugal fan is installed at the upper end of the cover plate, and the air inlet pipe is connected to the air inlet end of the centrifugal fan.

[0015] In another preferred embodiment of the present invention, a top cover is fixedly connected to the upper end of the filter box. The top cover is supported by iron material and has placement holes that cooperate with the magnetic plate. Support blocks are fixedly connected to the inner walls of the front and rear sides of the filter box.

[0016] In another preferred embodiment of the present invention, the filter cylinder includes a mesh cylinder, and filter cotton is fixedly connected to the inner wall of the mesh cylinder.

[0017] In another preferred embodiment of the present invention, a plurality of shock-absorbing pads are fixedly connected to the lower end of the base plate. The shock-absorbing pads are made of rubber and have anti-slip textures at the lower end.

Simultaneously, the cover is slidably connected to the base plate via a slide rail, and with the help of limiting components, the cover can be quickly opened and closed, solving the problem of cumbersome disassembly and installation of traditional soundproof covers, thus facilitating equipment maintenance. Furthermore, the U-shaped rubber sealing strip on the outer side panel further enhances the sealing and sound insulation effect, while the rubber vibration damping pad at the bottom of the base plate reduces noise generated by vibration transmission, improving noise reduction performance in multiple dimensions.

[0020] 2. Improved air filtration and convenient component replacement. The filter cartridge in the filter assembly includes a mesh cylinder and inner filter cotton, effectively filtering dust and impurities from the air. The centrifugal fan enhances air intake power, ensuring a stable supply of filtered clean air to the air compressor and reducing wear on components. Furthermore, the filter box's top cover is made of iron, allowing for quick assembly and disassembly through its interaction with a magnetic plate. The support block provides stable support for the filter assembly, simplifying replacement and meeting the air quality requirements of high-precision production environments while also satisfying the air compressor's heat dissipation needs.

[0021] 3. The structural design is more rational, resulting in greater stability and reliability.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention.

[0029] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.

[0030] like Figures 1-4As shown, a low-noise screw air compressor includes a base plate 1, with the air compressor body 20 mounted on the upper end of the base plate 1. Two side plates 3 are fixedly connected to the upper end of the base plate 1, and two slide rails 18 are fixedly connected to the upper end of the base plate 1. A cover plate 2 is slidably connected to both slide rails 18. The cover plate 2 can slide freely along the slide rails 18, allowing the air compressor body 20 to be closed and opened. When maintenance is required, sliding the cover plate 2 exposes the internal equipment, making operation convenient. Both the cover plate 2 and the side plates 3 are double-layer composite panels. Sound insulation cotton is provided on the inner wall of the cover plate 2 and the adjacent sides of the two side plates 3. A sound barrier is formed through the air layer between the double-layer panels. Combined with the sound insulation cotton provided on the inner wall of the cover plate 2 and the adjacent sides of the two side plates 3, the porous structure of the sound insulation cotton absorbs sound wave energy, effectively blocking the noise generated during the operation of the air compressor. Both side plates 3 are equipped with... The heat dissipation holes 4 allow the heat generated during air compressor operation to dissipate through the holes, preventing the equipment from overheating and affecting its operating efficiency and service life. Rubber sealing strips are fixedly connected to the outer sides of both side plates 3. These U-shaped rubber sealing strips fill the gap between the cover plate 2 and the side plates 3 when the cover plate 2 is closed, enhancing the overall sealing and further preventing noise leakage. Multiple shock-absorbing pads are fixedly connected to the lower end of the base plate 1. These pads are made of rubber and have anti-slip textures at their lower ends. During operation, the vibration generated by the air compressor is transmitted to the shock-absorbing pads through the base plate 1. The rubber pads absorb vibration energy through their elastic deformation, reducing the transmission of vibration to the ground and thus reducing noise. Simultaneously, the anti-slip textures increase the friction between the base plate 1 and the ground, preventing the equipment from sliding during operation.

[0031] The two side plates 3 are equipped with limiting components on opposite sides. The limiting components are used to limit the cover plate 2. The limiting components include two rotating shafts 5 rotatably connected to the side plates 3. A rotating plate 6 is fixedly connected to each of the two rotating shafts 5. A guide rod 8 is rotatably connected to each of the two rotating plates 6. A pressure block 7 is fixedly connected to the side of each guide rod 8 near the side plate 3. The two guide rods 8 and the corresponding rotating plates 6 are elastically connected by springs 9. When the cover plate 2 slides to the closed position, the rotating plate 6 is rotated so that the pressure block 7 is aligned with the edge of the cover plate 2. The elastic force of the spring 9 will push the guide rod 8, causing the pressure block 7 to press tightly against the cover plate 2, thereby fixing the cover plate 2 and preventing it from sliding due to vibration during equipment operation.

[0032] Each of the two side plates 3 is equipped with two sets of positioning components. The positioning components include through holes on the rotating shaft 5, and fixing blocks 11 are fixedly connected to the side plates 3. The fixing blocks 11 have round holes, and positioning pins 10 are slidably connected through the through holes. The positioning pins 10 pass through the round holes, and each positioning pin 10 has a threaded layer. Each threaded layer is threaded with a nut. When the rotating plate 6 rotates to the appropriate position, the positioning pins 10 are passed through the through holes on the rotating shaft 5 and the round holes on the fixing blocks 11, and then the nuts are tightened to fix the rotating shaft 5, thereby keeping the rotating plate 6 in the current position and ensuring that the fixing effect of the limiting components on the cover plate 2 is stable and reliable.

[0033] The upper end of the cover plate 2 is connected to a vertical pipe 16, and a filter box 15 is fixedly connected to the upper end of the vertical pipe 16. The upper end of the vertical pipe 16 communicates with the top space of the filter box 15. The filter box 15 is equipped with a filter assembly, which includes a magnetic plate 17. A filter cylinder 19 is fixedly connected to the lower end of the magnetic plate 17. The filter cylinder 19 includes a mesh cylinder, and filter cotton is fixedly connected to the inner wall of the mesh cylinder. An air inlet pipe 14 is fixedly connected through the magnetic plate 17. A centrifugal fan 13 is installed at the upper end of the cover plate 2. The air inlet pipe 14 and the centrifugal fan 13 are connected. The air compressor body 20 is connected to the air intake end. Outside air enters the filter assembly through the air intake pipe 14 and then enters the filter cylinder 19. The mesh cylinder can block larger impurities, while the filter cotton further filters fine dust and impurities in the air. The filtered clean air enters the top space of the filter box 15 and then enters the space enclosed by the cover plate 2, side plate 3 and bottom plate 1 through the vertical pipe 16. When the air compressor body 20 is running, it can draw in clean air, and at the same time, excess gas will be discharged through the heat dissipation hole 4 to dissipate heat from the air compressor body 20.

[0034] The filter box 15 is fixedly connected to a top cover 12, which is made of iron. The top cover 12 has a placement hole that mates with the magnetic plate 17. Support blocks are fixedly connected to the inner walls of the front and rear sides of the filter box 15. The support blocks support the filter assembly, allowing the filter assembly to be stably placed inside the filter box 15. When the filter assembly needs to be replaced, since the top cover 12 is made of iron, the magnetic plate 17 will be attracted to the top cover. The filter assembly can be replaced simply by removing the top cover 12 together with the filter assembly. The operation is simple and convenient.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
