Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a dustproof device for screw air compressors that is easy to clean. Background Technology

[0002] A screw air compressor is a positive displacement compressor that uses a pair of meshing male and female rotors rotating at high speed within a casing to achieve gas intake, compression, and discharge. Due to its compact structure, stable operation, high efficiency, and easy maintenance, it is widely used in industries such as machinery manufacturing, chemicals, textiles, electronics, and automobiles. As the core power equipment of a factory's air supply system, its long-term stable operation is crucial to ensuring the normal operation of the production line. However, screw air compressors need to continuously draw in a large amount of ambient air during operation. If the air contains dust, oil mist, or impurities, it will directly enter the main unit, causing rotor wear, oil deterioration, reduced cooling efficiency, and even system failure, seriously affecting equipment lifespan and operational safety. Therefore, to ensure the cleanliness of the intake air, screw air compressors are usually equipped with dustproof devices, especially dust filters at the heat dissipation holes or air inlets, to intercept external contaminants.

[0003] Existing dustproof devices for screw air compressors mostly adopt fixed dustproof mesh structures. Although they can effectively block large dust particles in the early stages, due to the lack of a design that facilitates disassembly or online cleaning, the dustproof mesh is easily clogged by dust, fibers, or oil after a period of use in high-dust environments such as industrial plants. This leads to increased air intake resistance, decreased heat dissipation efficiency, and consequently, overheating of the equipment, increased energy consumption, or even shutdown protection. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof device for screw air compressors that is easy to clean. This solves the problem that existing dustproof devices for screw air compressors mostly adopt a fixed dustproof mesh structure. Although it can effectively block large dust particles in the early stages, it lacks a design that allows for easy disassembly or online cleaning. After a period of use in high-dust environments such as industrial plants, the dustproof mesh is easily clogged by dust, fibers, or oil, leading to increased air intake resistance, decreased heat dissipation efficiency, and consequently, overheating, increased energy consumption, or even shutdown protection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dustproof device for easy cleaning of a screw air compressor includes a screw air compressor body and several air inlets on both sides of the screw air compressor body. Each air inlet is bolted with a dust cover. Crossbars are provided on both sides of the screw air compressor body. A movable plate is slidably connected to the top of each crossbar, and a horizontally moving structure that cooperates with the movable plate is provided at the bottom of each crossbar. One end of each crossbar is connected to the side wall of the screw air compressor body via a vertical lifting structure, and the other end is connected to the side wall of the screw air compressor body via a vertical sliding structure. A cleaning brush that fits against the side wall of the dust cover is connected to the top of one side of the movable plate via a driving structure. A dust suction assembly connected to the movable plate is provided at the bottom of the cleaning brush.

[0006] Preferably, the vacuuming assembly includes a connecting pipe with one end extending through a movable plate and a vacuum hood connected to one end of the connecting pipe, the other end of which is connected to a vacuuming pipe for connection with a vacuuming device.

[0007] Preferably, the drive structure includes a drive motor connected to the top of the movable plate via a mounting sleeve, and the output shaft of the drive motor is connected to one side of the cleaning brush.

[0008] Preferably, the top of the crossbar is provided with a moving groove, the moving plate is slidably connected to the inside of the moving groove, a toothed plate is connected to one side of the bottom of the crossbar, the bottom of the toothed plate is connected to a gear disk through tooth meshing, and a drive motor II that cooperates with the gear disk is installed on one side of the bottom of the moving plate.

[0009] Preferably, two symmetrically arranged vertical mounting boxes are connected to both sides of the screw air compressor body. Each of the two vertical mounting boxes has a sliding groove on the side that is close to each other, which slides with the end of the crossbar. The vertical sliding structure includes a guide rod connected inside the vertical mounting box and sliding with the end of the crossbar.

[0010] Preferably, the vertical lifting structure includes a lead screw rotatably connected inside the vertical mounting box and threadedly engaged with the end of the crossbar, and a drive motor mounted on the top of the vertical mounting box and engaged with the lead screw.

[0011] This utility model has the following beneficial effects: Through the coordinated operation of the crossbar, moving plate, horizontal moving structure, and drive structure, the cleaning brush achieves comprehensive cleaning of the dust cover surface, avoiding the tedious process of manual disassembly and cleaning. The combined design of the vertical lifting structure and the vertical sliding structure gives the crossbar height adjustment capability, adapting to dust covers in different installation positions and ensuring cleaning fit and effectiveness. The dust suction component is integrated into the bottom of the cleaning brush, which immediately sucks up dust while cleaning, preventing dust from scattering and causing secondary pollution or re-adhesion, further improving the cleaning effect.

Detailed Implementation

[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, this embodiment of a dustproof device for a screw air compressor that is easy to clean includes a screw air compressor body 1 and several air inlets 7 opened on both sides of the screw air compressor body 1. Each air inlet 7 is bolted to a dust cover 8. A crossbar 2 is provided on both sides of the screw air compressor body 1. A movable plate 4 is slidably connected to the top of the crossbar 2. A horizontal moving structure that cooperates with the movable plate 4 is provided at the bottom of the crossbar 2. One end of the crossbar 2 is connected to the side wall of the screw air compressor body 1 through a vertical lifting structure, and the other end is connected to the side wall of the screw air compressor body 1 through a vertical sliding structure. A cleaning brush 15 that fits against the side wall of the dust cover 8 is connected to the top of one side of the movable plate 4 through a driving structure. A dust suction component connected to the movable plate 4 is provided at the bottom of the cleaning brush 15.

[0017] When the screw air compressor body 1 is running, external air enters the equipment through several air inlets 7 on both sides to meet the airflow requirements for heat dissipation and compression. Dust covers 8, installed inside each air inlet 7 and fixed with bolts, first intercept impurities such as dust, fibers, and oil mist carried in the air, preventing contaminants from entering the main unit and causing rotor wear or lubricating oil contamination. As the running time increases, the intercepted dust gradually accumulates on the surface of the dust covers 8. At this point, the operator does not need to stop the machine to remove the dust covers 8; they only need to activate the drive structure, which is installed on the top side of the moving plate 4 and drives the cleaning brush 15, which is tightly fitted to the side wall of the dust cover 8, to reciprocate. Simultaneously, the horizontal moving structure at the bottom of the crossbar 2 drives the moving plate... 4. Slide along the top of the crossbar 2 so that the cleaning brush 15 can cover the entire outer surface of the dust cover 8 for horizontal cleaning; one end of the crossbar 2 is connected to the side wall of the screw air compressor body 1 through a vertical lifting structure, and the other end is connected to the side wall of the screw air compressor body 1 through a vertical sliding structure, so that the entire crossbar 2 assembly can be adjusted up and down according to the height position of the dust cover 8, ensuring that the cleaning brush 15 always maintains effective contact with the dust cover 8; while the cleaning brush 15 scrapes away the accumulated dust, the dust suction component set at its bottom is activated simultaneously to suck up and collect the dust brushed off immediately, avoiding secondary dust or dust falling into the equipment; the entire cleaning process can be completed while the equipment is running or in a short pause, without the need to disassemble bolts or replace parts, which significantly improves maintenance efficiency and ease of operation.

[0018] Example 2 Please see Figure 1-5 As shown in this embodiment, a dustproof device for a screw air compressor that is easy to clean includes a dust collection assembly comprising a connecting pipe 14 with one end penetrating a movable plate 4 and a dust collection hood 18 connected to one end of the connecting pipe 14. The other end of the connecting pipe 14 is connected to a dust collection pipe 13 for connection with a dust collection device. Specifically, through the arrangement of the connecting pipe 14, the dust collection hood 18 and the dust collection pipe 13, the dust collection hood 18 is located at the bottom of the cleaning brush 15 and communicates with the external dust collection pipe 13 through the connecting pipe 14 penetrating the movable plate 4. While the cleaning brush 15 scrapes away the dust accumulated on the surface of the dust collection hood 8, the dust collection device generates negative pressure through the dust collection pipe 13, so that the dust is immediately drawn away through the dust collection hood 18 and the connecting pipe 14, thereby achieving the effects of preventing dust from being re-entrained, avoiding pollution of the internal environment of the equipment, and improving the thoroughness of cleaning.

[0019] The top of the crossbar 2 is provided with a movable groove 10, and the movable plate 4 is slidably connected to the inside of the movable groove 10. A toothed plate 9 is connected to one side of the bottom of the crossbar 2. The bottom of the toothed plate 9 is connected to a gear disk 17 through a toothed engagement. A second drive motor 16 that cooperates with the gear disk 17 is installed on one side of the bottom of the movable plate 4. Specifically, through the arrangement of the movable groove 10, toothed plate 9, gear disk 17, second drive motor 16 and movable plate 4, the movable plate 4 is slidably embedded in the movable groove 10 at the top of the crossbar 2. The second drive motor 16 installed at its bottom drives the gear disk 17 to rotate. The gear disk 17 meshes with the toothed plate 9 fixed at the bottom of the crossbar 2, thereby driving the movable plate 4 to move horizontally back and forth along the crossbar 2. This achieves the effect of automatically covering the entire width of the dust cover 8 with the cleaning brush 15, without manual intervention, and improving the uniformity of cleaning and the degree of automation.

[0020] Example 3 Please see Figure 1-5 As shown in this embodiment, a dustproof device for a screw air compressor that is easy to clean has a drive structure including a drive motor 6 connected to the top of a movable plate 4 via a mounting sleeve 5. The output shaft of the drive motor 6 is connected to one side of a cleaning brush 15. Specifically, through the arrangement of the drive motor 6, the mounting sleeve 5, and the cleaning brush 15, the drive motor 6 is fixed to the top of the movable plate 4 via the mounting sleeve 5, and its output shaft is directly connected to one side of the cleaning brush 15. After starting, it drives the cleaning brush 15 to rotate at high speed, and in conjunction with the lateral movement, it achieves dynamic brushing of the surface of the dust cover 8, thereby enhancing the dust removal force, effectively removing adhesive dust, and improving cleaning efficiency.

[0021] Two symmetrically arranged vertical mounting boxes 3 are connected to both sides of the screw air compressor body 1. Each of the two vertical mounting boxes 3 has a sliding groove on the side closest to each other, which slides with the end of the crossbar 2. The vertical sliding structure includes a guide rod connected inside the vertical mounting box 3 and sliding with the end of the crossbar 2. Specifically, through the arrangement of the vertical mounting box 3, the sliding groove and the guide rod, the vertical mounting boxes 3 symmetrically arranged on both sides of the screw air compressor body 1 have sliding grooves. One end of the crossbar 2 is inserted into the sliding groove and slides with the internal guide rod to form a vertical sliding structure. This structure provides guidance and support during the lifting and lowering of the crossbar 2, restricts its swaying and deviation, and achieves the effects of ensuring the smooth operation of the crossbar 2, maintaining the fitting accuracy between the cleaning brush 15 and the dust cover 8, and improving the overall structural reliability.

[0022] The vertical lifting structure includes a lead screw 12 rotatably connected inside the vertical mounting box 3 and threadedly engaged with the end of the crossbar 2, and a drive motor 11 installed at the top of the vertical mounting box 3 and engaged with the lead screw 12. Specifically, through the arrangement of the lead screw 12, the drive motor 11 and the crossbar 2, the drive motor 11 is installed at the top of the vertical mounting box 3, driving the internally rotatably connected lead screw 12 to rotate. Since the lead screw 12 is threadedly engaged with the end of the crossbar 2, it drives the crossbar 2 to move up and down along the vertical mounting box 3, realizing height adjustment. This achieves the effect of flexibly adjusting the height of the cleaning brush 15 according to the installation position of the dust cover 8, ensuring comprehensive and effective contact, and adapting to different models or maintenance needs.

[0023] In the complete working process of this screw air compressor with an easy-to-clean dustproof device, when the screw air compressor body 1 is running, external air enters the equipment through several air inlets 7 on both sides to meet the airflow required for heat dissipation and compression. Each air inlet 7 has a dust cover 8 bolted to it, which first intercepts impurities such as dust, fibers, and oil mist carried in the air, preventing contaminants from entering the main unit. As the running time increases, dust gradually accumulates on the surface of the dust cover 8. At this point, the operator does not need to stop the machine to disassemble it; they only need to start the drive motor 6. This motor is fixed to the top of the moving plate 4 by the mounting sleeve 5, and its output shaft directly drives the cleaning brush 15 to rotate at high speed. Simultaneously, the drive motor 16 is installed at the bottom of one side of the moving plate 4, driving the gear disk 17 to rotate. The gear disk 17 meshes with the toothed plate 9 fixed to one side of the bottom of the crossbar 2, thereby driving the moving plate 4 to slide horizontally back and forth along the moving groove 10 opened at the top of the crossbar 2, allowing the rotating cleaning brush 15 to dynamically sweep the entire outer surface of the dust cover 8. To adapt to different heights... The dust cover 8 and the vertical mounting box 3 are symmetrically arranged on both sides of the screw air compressor body 1. The interior of the box has a guide rod to form a vertical sliding structure. One end of the crossbar 2 is inserted into the sliding groove opened in the side wall of the vertical mounting box 3 and slides with the guide rod to provide stable guidance. The other end is threaded with the lead screw 12. The lead screw 12 is rotatably connected to the interior of the vertical mounting box 3 and is driven to rotate by the drive motor 11 installed at the top of the vertical mounting box 3, thereby driving the crossbar 2 to rise and fall in the vertical direction, so as to achieve precise adjustment of the height of the cleaning brush 15. During the cleaning process, the dust collection components work simultaneously. The dust collection hood 18 is located at the bottom of the cleaning brush 15, and is connected to the dust collection pipe 13 through the moving plate 4 via the connecting pipe 14. The external dust collection equipment generates negative pressure through the dust collection pipe 13, which immediately draws away the dust scraped off by the cleaning brush 15 through the dust collection hood 18 and the connecting pipe 14 and collects it in a concentrated manner, avoiding secondary dust or dust falling into the equipment. The entire cleaning process can be completed automatically when the equipment is briefly paused or running at low load, without the need to disassemble the dust cover 8 or use tools, which significantly improves maintenance efficiency.

[0024] This device effectively solves the problems of increased air intake resistance, decreased heat dissipation efficiency, overheating, and even shutdown caused by dust accumulation and blockage of dust covers in existing technologies. Specifically, the rotational cooperation between the drive motor 6 and the cleaning brush 15, combined with the horizontal movement of the moving plate 4, achieves efficient and full-coverage dynamic dust removal. The horizontal movement structure formed by the toothed plate 9, gear disk 17, and drive motor 16 ensures automated and uniform cleaning. The vertical lifting structure formed by the lead screw 12 and drive motor 11, combined with the guide rod and the sliding groove in the vertical mounting box 3, makes the cleaning height adjustable and highly adaptable. The dust collection component achieves immediate dust recovery through the dust collection cover 18, connecting pipe 14, and dust collection pipe 13, eliminating secondary pollution.
