Description

Technical Field

[0001] This invention relates to the field of waste gas purification technology, specifically a filtration device for a gaseous conveying compressor used in environmental engineering construction. Background Technology

[0002] In environmental engineering construction, gaseous conveying compressors are widely used in fields such as waste gas treatment, gas recovery and material conveying. However, the gas sucked in by the compressor during operation often contains impurities such as dust, oil mist and moisture, which can easily lead to equipment wear, reduced efficiency and excessive emissions. Traditional filtration devices mostly use single-stage filter elements or mechanical separation structures, which have problems such as insufficient filtration accuracy, low dust holding capacity and frequent maintenance. Moreover, the filter components in the existing technology are difficult to install and disassemble conveniently, which makes the filtration efficiency easy to gradually decrease over time.

[0003] Patent CN217367822U discloses a filtration device for an air compressor. This patent includes a main body, a support structure, a photocatalytic filter, and an adsorption filter. The support structure is located at the lower end of the main body, the photocatalytic filter is located on the right side inside the main body, and the adsorption filter is located inside the main body. The adsorption filter includes a filter cylinder, an activated carbon layer, a spiral composite filter, and liquefied wire. The activated carbon layer is fixedly installed at the inner end of the filter cylinder, the spiral composite filter is fixedly installed at the inner end of the activated carbon layer, and the liquefied wire is fixedly installed at the inner end of the spiral composite filter. This filtration device for an air compressor, equipped with a spiral composite filter, can effectively filter harmful substances such as formaldehyde in the air, continuously performing fine filtration. The spiral distribution increases the contact surface with the air compared to a ring distribution, resulting in more comprehensive and effective filtration. Although this patent solves the aforementioned problems, it still suffers from the difficulty in conveniently installing and disassembling the filter components, leading to a gradual decrease in filtration efficiency over time. Therefore, a filtration device for a gaseous conveying compressor used in environmental engineering construction is proposed to address these problems. Summary of the Invention

[0033] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0034] 1. The filtration device of the gaseous conveying compressor used in this environmental protection project allows the adsorption box to be pulled out of the frame and detached from the filter cylinder via a pull plate, facilitating the cleaning of the activated carbon inside the adsorption box. The gas flow rate slows down after contacting the spiral plate, allowing sufficient time for it to enter the adsorption box for filtration, thus improving the filtration effect. The gas diffuses outwards due to centrifugal force, quickly entering the adsorption box for filtration, further enhancing filtration efficiency. The pull plate quickly locks onto the frame, making installation faster and more stable. When the adsorption box needs to be disassembled, a lever lowers the retaining shaft, causing it to disengage from the arc-shaped retaining block, thereby quickly pulling the adsorption box out of the frame and improving disassembly efficiency.

[0035] 2. The filter device of the gaseous conveying compressor used in this environmental protection project requires the gas to come into contact with the arc-shaped filter screen before entering the adsorption box. Impurities in the gas that easily clog the activated carbon are blocked by the arc-shaped filter screen and cannot enter the adsorption box, thus avoiding activated carbon clogging and improving the activated carbon adsorption efficiency. Rotating the nut makes the L-shaped clamping plate lock onto the adsorption box. Conversely, rotating the nut removes the L-shaped clamping plate. After the L-shaped clamping plate loses the nut's limit, it can be quickly removed from the adsorption box along with the arc-shaped filter screen for cleaning.

[0036] 3. The filter device of the gas conveying compressor used in this environmental protection project has a brush roller that contacts and rubs against the arc surface of the arc-shaped filter screen during rotation, thereby scraping off the impurities adhering to the arc-shaped filter screen. This prevents the gas from being unable to flow into the adsorption box due to the blockage of the arc-shaped filter screen by impurities. The friction between the brush roller and the scraping teeth causes the impurities stuck in the brush roller to fall off, further facilitating the cleaning of the arc-shaped filter screen by the brush roller.

[0037] 4. The filter device of the gaseous conveying compressor used in this environmental protection project allows impurities to slide down to the right side of the trapezoidal sewage channel. Opening the cover at this time can clean the impurities in the trapezoidal sewage channel out of the device, improving the impurity cleaning efficiency and preventing impurities from accumulating inside the device for a long time and affecting the operation of the device.

[0038] 5. The filter device of the gaseous conveying compressor used in this environmental protection project has an arc-shaped striking plate that rapidly resets and impacts the inner wall of the trapezoidal sewage channel, causing vibration between the arc-shaped striking plate and the inner wall of the trapezoidal sewage channel. This causes impurities adhering to the inner wall of the trapezoidal sewage channel to fall off quickly, improving the impurity collection effect. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please see Figures 1-8One embodiment of the present invention is: a filtration device for a gaseous conveying compressor used in environmental engineering construction, used to filter gas before it enters the compressor to prevent impurities from entering the compressor. The device includes a filter cylinder 1 for filtering the gas. An inlet pipe 2 is fixedly connected to the left side of the filter cylinder 1, and a delivery pipe 3 is fixedly connected to the right side of the filter cylinder 1. A primary filter screen 4 is fixedly connected to the inner wall of the inlet pipe 2, used to perform preliminary filtration on the gas just flowing into the inlet pipe 2 to prevent larger impurity particles from entering the filter cylinder 1. An adsorption box 6 is slidably connected to the inner wall of a frame 5. A pull plate 7 is fixedly connected to the side of the adsorption box 6 away from the filter cylinder 1. Activated carbon is installed inside the adsorption box 6. A fine filtration anti-clogging device 8 is installed inside the filter cylinder 1 to prevent large particles of impurities from entering the adsorption box 6 and contacting the activated carbon, causing blockage. A dirt discharge device 9 is installed at the bottom of the filter cylinder 1 to quickly discharge impurities.

[0050] In this embodiment, gas flows into the filter cylinder 1 from the inlet pipe 2. When the gas passes through the primary filter 4, larger impurity particles are filtered out by the primary filter 4. Then, the gas entering the filter cylinder 1 flows into the adsorption boxes 6 on both sides. The adsorption boxes 6 are equipped with activated carbon, and the pollutants in the gas are adsorbed by the activated carbon, so that the gas is further filtered. After the device is used up, the adsorption box 6 is pulled out from the frame 5 by the pull plate 7, so that the adsorption box 6 is separated from the filter cylinder 1. At this time, it is convenient to clean the activated carbon in the adsorption box 6.

[0051] Furthermore, the filter cartridge 1 includes an X-shaped support frame 10, which is fixedly connected to the inner wall of the air inlet pipe 2. The main shaft 11 is rotatably connected to the inner surface of the X-shaped support frame 10. A spiral plate 12 is fixedly connected to the circumferential surface of the main shaft 11. The spiral plate 12 is used to slow down the gas flow rate and make the gas accumulate in the filter cartridge 1.

[0052] In this embodiment, after the gas enters the filter cartridge 1, it comes into contact with the spiral surface of the spiral plate 12. The gas flow rate to the right slows down after being blocked by the spiral plate 12, thus allowing sufficient time to enter the adsorption box 6 for filtration, thereby improving the filtration effect. The motor is started, and the motor drives the main shaft 11 to rotate. The main shaft 11 drives the spiral plate 12 to rotate, which in turn causes the gas to rotate and generate centrifugal force. The gas diffuses in all directions under the influence of centrifugal force and quickly enters the adsorption box 6 for filtration, thereby improving the filtration efficiency.

[0053] Furthermore, the filter cartridge 1 also includes a convex plate 13, which is fixedly connected to the front and rear sides of the filter cartridge 1. Elastic telescopic rods 14 are fixedly connected to the upper and lower sides of the convex plate 13. A retaining shaft 16 is fixedly connected to the end of the elastic telescopic rod 14 away from the convex plate 13. A lever 17 is fixedly connected to the side of the retaining shaft 16 away from the retaining frame 5. An arc-shaped retaining block 15 is fixedly connected to the side of the pull plate 7 near the filter cartridge 1. A positioning hole is opened on the lower surface of the arc-shaped retaining block 15, and the inner wall of the positioning hole is engaged with the retaining shaft 16. The X-shaped support frame 10 is fixedly connected to the inner wall of the air supply pipe 3. A motor is fixedly connected to the right end of the main shaft 11, and the motor is fixedly connected to the right side of the X-shaped support frame 10. The convex plate 13 and the retaining frame 5 are fixedly connected to the left and right sides.

[0054] In this embodiment, during the process of inserting the pull plate 7 and the adsorption box 6 into the card frame 5, the pull plate 7 drives the arc-shaped card block 15 closer to the filter cylinder 1. When the arc-shaped card block 15 is close to the filter cylinder 1, its arc-shaped surface contacts the card shaft 16, and the card shaft 16 is pushed down by the guide of the arc-shaped surface. When the card shaft 16 descends, it squeezes the elastic telescopic rod 14, causing the elastic telescopic rod 14 to contract. When the adsorption box 6 is fully inserted into the card frame 5, the arc-shaped card block 15 stops moving. At this time, the hole opened on the lower surface of the arc-shaped card block 15 is aligned with the card shaft 1. 6. At this time, the elastic telescopic rod 14 extends upward and drives the locking shaft 16 to elastically reset and insert into the arc-shaped locking block 15, thereby quickly locking the arc-shaped locking block 15 and the pull plate 7 onto the frame 5 and the protruding plate 13, making the installation of the adsorption box 6 faster and more stable. When it is necessary to disassemble the adsorption box 6, the lever 17 is pushed down, and the lever 17 drives the locking shaft 16 to descend, causing the locking shaft 16 to be pulled away from the arc-shaped locking block 15. Then the pull plate 7 is pulled, thereby quickly pulling the adsorption box 6 out of the frame 5, improving the disassembly efficiency.

[0055] Working principle: Insert the adsorption box 6 and its internal activated carbon into the frame 5, then input the gas into the inlet pipe 2, and then flow into the filter cylinder 1 through the primary filter 4 in the inlet pipe 2. After entering the filter cylinder 1, the gas is blocked by the spiral plate 12 and flows slowly to the right in a spiral. Then the spiral plate 12 rotates and generates centrifugal force, causing the gas to diffuse in all directions and flow into the adsorption box 6. After being filtered by the activated carbon in the adsorption box 6, the gas flows out from the gas delivery pipe 3 and enters the compressor. After the gas delivery is completed, remove the adsorption box 6 from the frame 5 for cleaning, so as to facilitate the next gas filtration.

[0056] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the fine filtration anti-clogging device 8 includes an L-shaped clamping plate 81, which is clamped onto the inner surface of the adsorption box 6. An arc-shaped filter screen 82 is fixedly connected to the surface of the L-shaped clamping plate 81. The arc-shaped filter screen 82 is used to filter the gas entering the adsorption box 6. A positioning screw 83 is fixedly connected to the side of the adsorption box 6 away from the pull plate 7. The positioning screw 83 passes through the side of the L-shaped clamping plate 81 near the adsorption box 6 and extends out of the side of the L-shaped clamping plate 81 away from the adsorption box 6. A nut 84 is threadedly connected to the circumferential surface of the positioning screw 83.

[0057] In this embodiment, the L-shaped clamping plate 81 is inserted into the adsorption box 6. The L-shaped clamping plate 81 drives the arc-shaped filter screen 82 to be inserted into the adsorption box 6. Before the gas enters the adsorption box 6, it needs to come into contact with the arc-shaped filter screen 82. Impurities in the gas that easily clog the activated carbon are blocked by the arc-shaped filter screen 82 and cannot enter the adsorption box 6, thereby avoiding activated carbon clogging and improving the activated carbon adsorption efficiency. After the L-shaped clamping plate 81 is inserted into the adsorption box 6, the positioning screw 83 passes through the L-shaped clamping plate 81. At this time, rotating the nut 84 makes the L-shaped clamping plate 81 clamp onto the adsorption box 6. Conversely, rotating the nut 84 removes the L-shaped clamping plate 81. After the L-shaped clamping plate 81 loses the limitation of the nut 84, it can be quickly removed from the adsorption box 6 together with the arc-shaped filter screen 82 for cleaning, so that the gas can flow smoothly between the filter cartridge 1 and the adsorption box 6.

[0058] Furthermore, the fine filtration anti-clogging device 8 also includes a rotating connecting rod 85, which is fixedly connected to the inner surface of the spiral plate 12. A brush roller 86 is fixedly connected to the circumferential surface of the rotating connecting rod 85. The brush roller 86 is used to brush away impurities adhering to the arc-shaped filter screen 82. A support plate 87 is fixedly connected to the bottom inner wall of the filter cylinder 1. An arc-shaped plate 88 is fixedly connected to the top of the support plate 87. A through groove is opened on the inner side of the arc-shaped plate 88, and the through groove is used to allow impurities to fall from the arc-shaped plate 88 to below the arc-shaped plate 88. A scraper tooth 89 is fixedly connected to the upper surface of the arc-shaped plate 88. The scraper tooth 89 is used to scrape away impurities adhering to the brush roller 86. The circumferential surface of the brush roller 86 abuts against the arc surface of the arc-shaped filter screen 82. The nut 84 and the L-shaped clamping plate 81 abut against the side away from the adsorption box 6. The arc-shaped filter screen 82 is clamped to the inner surface of the adsorption box 6.

[0059] In this embodiment, when the spiral plate 12 rotates, it drives the rotating connecting rod 85 to rotate around the axis of the main shaft 11. The rotating connecting rod 85 drives the brush roller 86 to rotate around the axis. During the rotation of the brush roller 86, it comes into contact with the arc surface of the arc-shaped filter screen 82 and rubs against it, thereby scraping off the impurities adhering to the arc-shaped filter screen 82. This prevents the gas from flowing into the adsorption box 6 due to the blockage of the arc-shaped filter screen 82 by the impurities. When the brush roller 86 moves to the bottom of the filter cylinder 1, it comes into contact with the scraping teeth 89 on the support plate 87 and the arc plate 88. The friction between the brush roller 86 and the scraping teeth 89 causes the impurities stuck in the brush roller 86 to fall off, further facilitating the brush roller 86 to clean the arc-shaped filter screen 82.

[0060] Working principle: The arc-shaped filter screen 82 prevents inorganic impurities that are difficult to be adsorbed by activated carbon from entering the adsorption box 6. The spiral plate 12 drives the rotating connecting rod 85 and the brush roller 86 to rotate circumferentially and sweep away the inorganic impurities adhering to the arc-shaped filter screen 82. The impurities fall into the gaps of the brush roller 86 and move with the brush roller 86. When the brush roller 86 contacts the scraper tooth 89, the impurities are shaken off from the gaps of the brush roller 86, so that the gas can flow smoothly between the filter cylinder 1 and the adsorption box 6.

[0061] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the dirt discharge device 9 includes a trapezoidal sewage channel 91, which is fixedly connected to the lower surface of the filter cylinder 1. The filter cylinder 1 is used to receive impurities falling from the arc plate 88 and to transport the impurities to the right end through the inclined surface. A cover plate 92 is hinged to the right side of the filter cylinder 1. A torsion rod 93 is hinged to the inner surface of the support plate 87. A torsion spring is provided at the hinge point between the torsion rod 93 and the support plate 87, and the torsion spring provides a force for the torsion rod 93 to rotate and reset.

[0062] In this embodiment, the impurities scraped off by the scraper teeth 89 fall onto the arc-shaped plate 88, and then fall down through the through groove on the arc-shaped plate 88 onto the trapezoidal drainage channel 91. The impurities then slide down to the right along the slope of the trapezoidal drainage channel 91. At this time, opening the cover plate 92 can clean the impurities in the trapezoidal drainage channel 91 out of the device, improving the impurity cleaning efficiency and preventing impurities from accumulating inside the device for a long time and affecting the operation of the device.

[0063] Furthermore, the dirt discharge device 9 also includes a sleeve rod 94, which is fixedly connected to the circumferential surface of the torsion rod 93. An arc-shaped striking plate 95 is fixedly connected to the circumferential surface of the torsion rod 93. The arc-shaped striking plate 95 is used to strike the inner wall of the trapezoidal sewage channel 91, causing the impurities adhering to the inner wall of the trapezoidal sewage channel 91 to fall off. A deflecting plate 96 is fixedly connected to the circumferential surface of the right end of the rotating connecting rod 85, and a torsion plate 97 is fixedly connected to the circumferential surface of the right end of the torsion rod 93. The arc-shaped striking plate 95 abuts against the front side of the inner wall of the trapezoidal sewage channel 91, and the front side of the deflecting plate 96 abuts against the rear side of the torsion plate 97.

[0064] In this embodiment, the rotating connecting rod 85 drives the actuating plate 96 to rotate circumferentially. When the actuating plate 96 rotates to the bottom of the filter cylinder 1, it contacts the torsion plate 97. The actuating plate 96 pushes the torsion plate 97 to rotate and move by an angle. Then, the actuating plate 96 continues to rotate upward and away from the torsion plate 97. The torsion plate 97 drives the torsion rod 93 and the arc-shaped striking plate 95 to rotate by a certain angle. When the actuating plate 96 moves away from the torsion plate 97, the elastic reset action of the torsion spring drives the torsion rod 93 and the torsion plate 97 to reset rapidly. The torsion rod 93 then drives the arc-shaped striking plate 95 to reset rapidly and strike the inner wall of the trapezoidal sewage channel 91, causing vibration between the arc-shaped striking plate 95 and the inner wall of the trapezoidal sewage channel 91. This causes impurities adhering to the inner wall of the trapezoidal sewage channel 91 to fall off quickly, improving the impurity collection effect.

[0065] Working principle: Inorganic impurities fall downwards into the trapezoidal drainage channel 91 for rapid collection, facilitating cleaning by staff. The actuating plate 96 moves the torsion plate 97, causing the torsion plate 97 to rotate. Then, the actuating plate 96 is driven by the rotating connecting rod 85 to rotate away from the torsion plate 97. At this time, the torsion plate 97 and the torsion rod 93 are reset by the torsion spring and drive the arc-shaped striking plate 95 to strike the inner wall of the trapezoidal drainage channel 91, causing the remaining inorganic impurities adhering to the inner wall to fall off and accumulate, further improving cleaning efficiency.
