Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an anti-clogging and dustproof device for screw compressors. Background Technology

[0002] A screw compressor is a positive displacement compressor that uses a pair of meshing male and female rotors to continuously rotate within a sealed cavity to achieve gas intake, compression, and discharge. It boasts advantages such as compact structure, stable operation, high efficiency, low noise, and easy maintenance, and is widely used in various fields including industrial manufacturing, energy, chemical, food, and pharmaceutical industries. As the core power unit of a modern factory's air supply system, its long-term, efficient, and stable operation directly affects the reliability and energy efficiency of the entire production system. Because screw compressors continuously draw in large amounts of ambient air during operation, if the air contains impurities such as dust, fibers, or oil mist, it will not only contaminate the lubricating oil and accelerate rotor wear, but may also block cooling air ducts, severely affecting heat dissipation and leading to overheating, increased energy consumption, or even equipment failure and shutdown.

[0003] Existing dustproof devices for screw compressors mostly adopt fixed dustproof nets or simple filter covers. Although they can effectively intercept large dust particles in the early stages, as the usage time increases, the intercepted dust will continue to accumulate on the surface of the dustproof net, causing the mesh to become clogged, the ventilation resistance to increase, and thus the heat dissipation efficiency to be weakened, leading to abnormal temperature rise of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging and dustproof device for screw compressors, which solves the problem that existing screw compressor dustproof devices mostly adopt fixed dustproof nets or simple filter cover structures. Although they can effectively intercept large dust particles in the early stage, as the usage time increases, the intercepted dust will continue to accumulate on the surface of the dustproof net, causing the mesh to become clogged, the ventilation resistance to increase, and thus the heat dissipation efficiency to be weakened, leading to abnormal temperature rise of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dustproof and anti-clogging device for a screw compressor includes a screw compressor body and two ventilation openings respectively opened on both sides of the screw compressor body. A dustproof net is bolted to the inside of each ventilation opening. A vertical plate is provided on one side of each dustproof net. A cleaning brush is provided between the vertical plate and the dustproof net. A vertical groove is opened on one side of the vertical plate. A sliding rod is slidably connected inside the vertical groove. A drive structure that cooperates with the cleaning brush is installed at one end of the sliding rod. The top part of the vertical plate is slidably connected to the side wall of the screw compressor body through the sliding structure. The bottom part of the vertical plate is connected to the side wall of the screw compressor body through the horizontal moving structure. A lifting structure that cooperates with the sliding rod is provided on the top and bottom of one side of the vertical plate.

[0006] Preferably, the drive structure includes a drive motor connected to the end of the sliding rod via a mounting plate, and the output end of the drive motor rotates through the sliding rod and connects to the cleaning brush.

[0007] Preferably, both ends of the vertical plate are fixedly connected to movable rods, and the sliding structure includes a top plate that is bolted to the side wall of the screw compressor body, and a guide rod that slides with the movable rods is connected to the top of the top plate.

[0008] Preferably, a soft brush is detachably connected to one side of the cleaning brush, and the surface of the soft brush is in contact with the side wall of the dustproof net.

[0009] Preferably, the horizontal moving structure includes a bottom plate bolted to the side wall of the screw compressor body and two fixed plates connected to the bottom of the bottom plate. A lead screw threaded to the moving rod is rotatably connected between the two fixed plates, and a drive motor cooperating with the lead screw is installed on one side of the fixed plate.

[0010] Preferably, the lifting structure includes a push cylinder connected to the side wall of the vertical plate via a side plate, the output end of the push cylinder being connected to the side wall of the sliding rod, and a collection groove being provided at the top of the bottom plate, with a collection box inserted inside the collection groove.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Example 1 Please see Figure 1-5 As shown, an anti-clogging and dustproof device for a screw compressor according to this embodiment includes a screw compressor body 1 and two ventilation openings respectively opened on both sides of the screw compressor body 1. A dustproof net 2 is bolted to the inside of each ventilation opening. A vertical plate 7 is provided on one side of each dustproof net 2. A cleaning brush 9 is provided between the vertical plate 7 and the dustproof net 2. A vertical groove 12 is opened on one side of the vertical plate 7. A sliding rod 8 is slidably connected inside the vertical groove 12. A drive structure that cooperates with the cleaning brush 9 is installed at one end of the sliding rod 8. The top part of the vertical plate 7 is slidably connected to the side wall of the screw compressor body 1 through the sliding structure. The bottom part of the vertical plate 7 is connected to the side wall of the screw compressor body 1 through the horizontal moving structure. A lifting structure that cooperates with the sliding rod 8 is provided on the top and bottom of one side of the vertical plate 7.

[0017] In the actual operation of this technical solution, when the screw compressor body 1 is running, external air enters the equipment through the ventilation openings on both sides to dissipate heat. The dustproof net 2, installed inside the ventilation openings and fixed with bolts, first intercepts dust, fibers, and other impurities carried in the air, preventing them from entering the compressor and affecting the lubrication system or blocking the cooling channels. As the running time increases, the intercepted dust gradually accumulates on the surface of the dustproof net 2. At this time, the operator does not need to disassemble the entire dustproof structure, but only needs to activate the drive structure connected to one end of the sliding rod 8. This drive structure drives the sliding rod 8 to slide up and down in the vertical groove 12 opened on one side of the vertical plate 7. Since the cleaning brush 9 is set between the vertical plate 7 and the dustproof net 2 and is linked with the sliding rod 8, the lifting and lowering movement of the sliding rod 8 synchronously drives the cleaning brush 9 to perform a vertical scraping action along the surface of the dustproof net 2, thereby effectively removing the dust attached to the dustproof net 2. Meanwhile, the top of the vertical plate 7 is slidably connected to the side wall of the screw compressor body 1 through a sliding structure, while the bottom is connected to the side wall of the screw compressor body 1 through a horizontal moving structure. This allows the entire vertical plate 7 assembly to be moved outward horizontally as a whole when needed, facilitating in-depth maintenance or replacement of the cleaning brush 9 or dust screen 2. In addition, a lifting structure that cooperates with the sliding rod 8 is provided on the top and bottom of one side of the vertical plate 7. This lifting structure not only provides guidance and support for the sliding rod 8, but also ensures that it runs smoothly in the vertical groove 12, avoiding jamming or abnormal noise caused by vibration or uneven load, thereby ensuring the continuity and reliability of the cleaning process.

[0018] Example 2 Please see Figure 1-5 As shown in this embodiment, an anti-clogging and dustproof device for a screw compressor includes a drive structure comprising a drive motor 5 connected to the end of a sliding rod 8 via a mounting plate 6. The output end of the drive motor 5 rotates through the sliding rod 8 and connects to a cleaning brush 9. Specifically, through the arrangement of the drive motor 5, mounting plate 6, sliding rod 8, and cleaning brush 9, the drive motor 5 is fixed to the end of the sliding rod 8 via the mounting plate 6, and its output shaft rotates through the sliding rod 8 and is directly connected to the cleaning brush 9. After startup, it drives the cleaning brush 9 to rotate, and simultaneously, in coordination with the up-and-down movement of the sliding rod 8, the cleaning brush 9 rotates while vertically scraping, enhancing the ability to remove stubborn dust from the surface of the dustproof net 2, thereby improving dust removal efficiency, preventing local blockage, and extending the effective service life of the dustproof net 2.

[0019] A soft brush is detachably connected to one side of the cleaning brush 9. The surface of the soft brush is in contact with the side wall of the dustproof net 2. Specifically, through the setting of the soft brush and the cleaning brush 9, the soft brush is detachably connected to the side of the cleaning brush 9 facing the dustproof net 2, and its surface is tightly in contact with the side wall of the dustproof net 2. During the cleaning process, the soft material is used to penetrate into the gaps of the dustproof net 2 mesh for fine cleaning, avoiding damage to the mesh structure by the hard bristles. This achieves the effect of efficient cleaning and protection of the integrity of the dustproof net 2, easy replacement of worn parts, and reduced maintenance costs.

[0020] Example 3 Please see Figure 1-5 As shown in this embodiment, an anti-clogging and dustproof device for a screw compressor has movable rods 10 fixedly connected to both ends of a vertical plate 7. The sliding structure includes a top plate 4 bolted to the side wall of the screw compressor body 1. A guide rod 11 that slides with the movable rods 10 is connected to the top of the top plate 4. Specifically, through the arrangement of the top plate 4, the guide rod 11, and the movable rod 10, the movable rods 10 fixed at both ends of the vertical plate 7 slide with the guide rod 11 on the top plate 4, forming a sliding structure at the top of the vertical plate 7. This provides vertical guidance and support during the horizontal movement of the vertical plate 7 or the operation of the cleaning mechanism, limiting its swaying and deviation. This achieves the effects of improving the operational stability of the vertical plate 7, reducing vibration interference, and ensuring the fitting accuracy of the cleaning brush 9 and the dustproof net 2.

[0021] The horizontal moving structure includes a bottom plate 3 bolted to the side wall of the screw compressor body 1 and two fixed plates connected to the bottom of the bottom plate 3. A lead screw 16 threaded to the moving rod 10 is rotatably connected between the two fixed plates. A second drive motor 13 cooperating with the lead screw 16 is installed on one side of the fixed plate. Specifically, through the arrangement of the bottom plate 3, fixed plates, lead screw 16, second drive motor 13 and moving rod 10, the bottom plate 3 is fixed to the side wall of the screw compressor body 1, and a lead screw 16 threaded to the moving rod 10 is rotatably installed between the two fixed plates at its bottom. The second drive motor 13 drives the lead screw 16 to rotate, thereby driving the moving rod 10 and the vertical plate 7 connected to it to move horizontally as a whole, realizing horizontal cleaning and achieving the cleaning effect of the vertical plate 7 assembly being movable in the horizontal direction.

[0022] The lifting structure includes a push cylinder 17 connected to the side wall of the vertical plate 7 via a side plate 18. The output end of the push cylinder 17 is connected to the side wall of the sliding rod 8. A collection groove 14 is provided on the top of the bottom plate 3. A collection box 15 is inserted into the inside of the collection groove 14. Specifically, through the arrangement of the push cylinder 17, the side plate 18, the sliding rod 8, the collection groove 14 and the collection box 15, the push cylinder 17 is installed on the side wall of the vertical plate 7 via the side plate 18. Its output end is connected to the sliding rod 8, which is used to drive the sliding rod 8 to rise and fall in the vertical groove 12 to realize the cleaning action. At the same time, the collection box 15 is inserted into the collection groove 14 on the top of the bottom plate 3, which can collect the dust brushed off from the dustproof net 2 during the cleaning process.

[0023] In the complete working process of the anti-clogging and dustproof device for this screw compressor, when the screw compressor body 1 is running, external air enters the equipment through the ventilation openings on both sides to achieve heat dissipation. The dustproof net 2, which is fixed to the ventilation openings by bolts, first intercepts dust, fibers and other impurities in the air, preventing pollutants from entering the compressor and affecting the lubrication system or blocking the cooling air duct. As the running time increases, dust gradually accumulates on the surface of the dustproof net 2. At this time, the operator does not need to stop the machine to disassemble it, but only needs to start the drive motor 5. The motor is fixed to the end of the sliding rod 8 by the mounting plate 6. Its output end rotates through the sliding rod 8 and interacts with the cleaning brush. The brush 9 is directly connected, thereby driving the cleaning brush 9 to rotate; at the same time, the push cylinder 17 is installed on the side wall of the vertical plate 7 through the side plate 18, and its output end is connected to the side wall of the sliding rod 8. Under the extension and retraction of the cylinder, the sliding rod 8 is driven to slide up and down reciprocally along the vertical groove 12 opened on one side of the vertical plate 7, so that the cleaning brush 9 performs a vertical scraping action along the surface of the dustproof net 2 while rotating, effectively removing accumulated dust; in order to enhance the cleaning effect and protect the structure of the dustproof net 2, a soft brush is detachably connected to the side of the cleaning brush 9 facing the dustproof net 2. Its soft material can penetrate into the gaps of the mesh for fine cleaning without damaging the mesh surface; during the cleaning process, the dust brushed off Dust falls into the collection groove 14 at the top of the bottom plate 3 and is collected by the collection box 15 inserted therein, facilitating subsequent unified cleaning and preventing secondary dust generation. When deep maintenance is required on the cleaning mechanism or dust screen 2, the drive motor 13 can be started. This motor is installed on one side of the fixed plate below the bottom plate 3, driving the lead screw 16 rotatably connected between the two fixed plates to rotate. Since the lead screw 16 is threadedly engaged with the moving rods 10 fixed at both ends of the vertical plate 7, it drives the moving rods 10 and the entire vertical plate 7 assembly connected to them to move smoothly outward in the horizontal direction. During this process, the top of the vertical plate 7 is connected to the guide provided on the top plate 4 through the moving rod 10. The rod 11 slides in place, while the top plate 4 is bolted to the side wall of the screw compressor body 1, providing vertical guidance and support for the vertical plate 7, ensuring its stability and preventing swaying during horizontal movement and cleaning operations. At the same time, the bottom of the vertical plate 7 is precisely positioned by a horizontal movement structure consisting of the moving rod 10 and the lead screw 16, which, together with the top guide rod 11, ensures the smooth operation of the overall structure. In addition, the push cylinder 17, as the core component of the lifting structure, not only replaces the traditional complex transmission method, but also provides reliable and controllable lifting power for the sliding rod 8, effectively avoiding jamming or abnormal noise caused by equipment vibration, and ensuring continuous and reliable cleaning operations.

[0024] The beneficial effects are specifically reflected in the following aspects: Through the linkage of the drive motor 5, mounting plate 6, sliding rod 8, and cleaning brush 9, the cleaning brush 9 achieves rotation while vertically scraping, significantly improving the removal efficiency of stubborn dust accumulation, effectively preventing partial clogging of the dustproof net 2, and extending its service life; the detachable connection structure between the soft brush and the cleaning brush 9 ensures cleaning effectiveness while preventing damage to the dustproof net 2 surface by hard bristles, balancing functionality and protection, and facilitating the replacement of worn parts, reducing long-term maintenance costs; the lifting structure composed of the pushing cylinder 17, side plate 18, and sliding rod 8 provides a stable and reliable linear driving force for the cleaning action, simplifying the transmission system, reducing operational failures caused by vibration, and improving the reliability of the device in industrial environments; The horizontal moving structure formed by the bottom plate 3, fixed plate, lead screw 16, drive motor 13, and moving rod 10 allows the entire vertical plate 7 assembly to be moved horizontally without stopping the machine or removing bolts, greatly simplifying the inspection and replacement process of the cleaning brush 9 or dust screen 2 and improving maintenance efficiency. The sliding structure formed by the top plate 4, guide rod 11, and moving rod 10 provides vertical guidance and rigid support for the vertical plate 7 during horizontal movement and cleaning, effectively suppressing shaking and deviation, ensuring that the cleaning brush 9 is always in close contact with the dust screen 2, and guaranteeing cleaning quality. The collection trough 14 and collection box 15 are used to collect the dust that falls off during cleaning, preventing dust from scattering and causing secondary pollution or entering the equipment, thus improving the cleanliness and safety of the site.
