Description

Technical Field

[0015] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. The filtering device of the gas conveying compressor used in the construction of the environmental protection project uses a pull plate to pull the adsorption box out of the card frame and separate it from the filter cartridge, which is convenient for cleaning the activated carbon in the adsorption box. The flow rate of the gas slows down after contacting the spiral plate, so that there is sufficient time for the gas to enter the adsorption box for filtration, which improves the filtration effect.

[0016] 2. The filtering device of the gas conveying compressor used in the construction of this environmental protection project needs to contact the arc-shaped filter before the gas enters the adsorption box. The impurities in the gas that are easy to clog the activated carbon are blocked by the arc-shaped filter and cannot enter the adsorption box, thereby avoiding the blockage of the activated carbon and improving the adsorption efficiency of the activated carbon. Rotating the nut makes the L-shaped card clamped on the adsorption box, and vice versa, rotating to remove the nut. After the L-shaped card loses the limit of the nut, it can be quickly removed from the adsorption box together with the arc-shaped filter for cleaning.

[0017] 3. The filter device of the gas conveying compressor used in the construction of the environmental protection project, when the brush roller rotates, contacts and rubs with the arc surface of the arc filter, thereby scraping off the impurities adhering to the arc filter, preventing the gas from clogging the arc filter due to impurities and making it difficult to flow into the adsorption box. The friction between the brush roller and the scraping teeth causes the impurities stuck in the brush roller to fall off, further facilitating the brush roller to clean the arc filter.

[0018] 4. In the filtering device of the gas conveying compressor used in the construction of this environmental protection project, impurities slide to the right along the slope of the trapezoidal sewage channel. At this time, opening the cover can clean the impurities in the trapezoidal sewage channel out of the device, thereby improving the impurity cleaning efficiency and preventing impurities from accumulating inside the device for a long time and affecting the operation of the device.

[0019] 5. The filtering device of the gas conveying compressor used in the construction of this environmental protection project has an arc-shaped knocking plate that quickly resets and hits the inner wall of the trapezoidal sewage channel, causing vibration between the arc-shaped knocking plate and the inner wall of the trapezoidal sewage channel, so that impurities adhering to the inner wall of the trapezoidal sewage channel fall off quickly, thereby improving the impurity collection effect.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-8The filtration system of the present invention is as follows: the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system of the filtration system

[0024] In this embodiment, the gas flows into the filter cartridge 1 from the air inlet pipe 2. When the gas passes through the primary filter 4, the larger impurity particles are filtered out by the primary filter 4. The gas then enters the filter cartridge 1 and flows into the adsorption boxes 6 on the front and rear sides. Activated carbon is provided in the adsorption box 6. The pollutants in the gas are adsorbed by the activated carbon, so that the gas is further filtered. After the device is used, the adsorption box 6 is pulled out of the card frame 5 by the pull plate 7, so that the adsorption box 6 is separated from the filter cartridge 1. At this time, it is convenient to clean the activated carbon in the adsorption box 6.

[0025] 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, and the main shaft 11 is rotatably connected to the inner surface of the X-shaped support frame 10. The circumferential surface of the main shaft 11 is fixedly connected to a spiral plate 12, which is used to slow down the gas flow rate and make the gas gather in the filter cartridge 1.

[0026] In this embodiment, after the gas enters the filter cartridge 1, it contacts the spiral surface of the spiral plate 12. After the gas is blocked by the spiral plate 12, the flow rate to the right slows down, so that there is sufficient time for the gas 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, and the main shaft 11 drives the spiral plate 12 to rotate, thereby causing the gas to rotate and generate centrifugal force. The gas is affected by the centrifugal force and diffuses to the surroundings, quickly entering the adsorption box 6 for filtration, thereby improving the filtration efficiency.

[0027] 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, and the upper and lower sides of the convex plate 13 are fixedly connected with elastic telescopic rods 14, and the end of the elastic telescopic rod 14 away from the convex plate 13 is fixedly connected with a clamping shaft 16, and the side of the clamping shaft 16 away from the clamping frame 5 is fixedly connected with a paddle 17, and the arc-shaped clamping block 15 is fixedly connected to the side of the pull plate 7 close to the filter cartridge 1, and a positioning hole is provided on the lower surface of the arc-shaped clamping block 15, and the inner wall of the positioning hole is clamped with the clamping shaft 16, the X-shaped support frame 10 is fixedly connected to the inner wall of the gas pipe 3, the right end of the main shaft 11 is fixedly connected to the motor, and the motor is fixedly connected to the right side of the X-shaped support frame 10, and the convex plate 13 is fixedly connected to the left and right sides of the clamping frame 5.

[0028] In this embodiment, when the pull plate 7 and the adsorption box 6 are inserted into the card frame 5, the pull plate 7 drives the arc-shaped card block 15 to approach the filter cartridge 1. When the arc-shaped card block 15 approaches the filter cartridge 1, its arc surface contacts the card shaft 16, and the card shaft 16 is pushed down by the guidance of the arc 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 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 card shaft 16 to elastically reset and insert into the arc-shaped card block 15, and then quickly locks the arc-shaped card block 15 and the pull plate 7 on the card frame 5 and the protruding plate 13, making the adsorption box 6 installation faster and more stable. When the adsorption box 6 needs to be removed, the paddle 17 is pushed downward, and the paddle 17 drives the card shaft 16 to descend, so that the card shaft 16 is pulled out of the arc-shaped card block 15, and then the pull plate 7 is pulled, so that the adsorption box 6 is quickly pulled out from the card frame 5, thereby improving the disassembly efficiency.

[0029] Working principle: insert the adsorption box 6 and the activated carbon inside it into the card frame 5, then input the gas into the air inlet pipe 2, and then flow into the filter cartridge 1 through the primary filter 4 in the air inlet pipe 2. After entering the filter cartridge 1, the gas is blocked by the spiral plate 12 and flows slowly to the right in a spiral line. Then the spiral plate 12 rotates to generate centrifugal force to make the gas diffuse to the surroundings 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 pipe 3 and enters the compressor. After the gas delivery is completed, the adsorption box 6 is removed from the card frame 5 for cleaning to facilitate the next filtration of the gas.

[0030] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, the fine filtration anti-blocking device 8 includes an L-shaped card plate 81, which is clamped on the inner surface of the adsorption box 6. The surface of the L-shaped card plate 81 is fixedly connected with an arc-shaped filter screen 82, which is used to filter the gas entering the adsorption box 6. The 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 card plate 81 close to the adsorption box 6 and the side of the L-shaped card plate 81 away from the adsorption box 6. The nut 84 is threadedly connected to the circumferential surface of the positioning screw 83.

[0031] In this embodiment, the L-shaped card plate 81 is inserted into the adsorption box 6, and the L-shaped card plate 81 drives the arc filter 82 to be inserted into the adsorption box 6. Then, the gas needs to contact the arc filter 82 before entering the adsorption box 6, and the impurities in the gas that are easy to clog the activated carbon are blocked by the arc filter 82 and cannot enter the adsorption box 6, thereby avoiding the blockage of the activated carbon and improving the adsorption efficiency of the activated carbon. After the L-shaped card plate 81 is inserted into the adsorption box 6, the positioning screw 83 passes through the L-shaped card plate 81. At this time, the nut 84 is rotated to clamp the L-shaped card plate 81 on the adsorption box 6. Conversely, the nut 84 is rotated to remove the nut 84. After the L-shaped card plate 81 loses the limit of the nut 84, it can be quickly removed from the adsorption box 6 together with the arc filter 82 for cleaning, so that the gas can flow smoothly between the filter cartridge 1 and the adsorption box 6.

[0032] Furthermore, the fine filter anti-blocking device 8 also includes a rotating connecting rod 85, which is fixedly connected to the inner surface of the spiral plate 12. The circumferential surface of the rotating connecting rod 85 is fixedly connected to a brush roller 86, which is used to brush off impurities adhered to the arc filter 82. The support plate 87 is fixedly connected to the inner wall of the bottom of the filter cylinder 1. The top of the support plate 87 is fixedly connected to the arc plate 88. A through groove is provided on the inner side of the arc plate 88, and the through groove is used to allow impurities to fall from the arc plate 88 to the bottom of the arc plate 88. The upper surface of the arc plate 88 is fixedly connected to a scraper 89, which is used to scrape off impurities adhered to the brush roller 86. The circumferential surface of the brush roller 86 abuts the arc surface of the arc filter 82, the nut 84 abuts the side of the L-shaped clamping plate 81 away from the adsorption box 6, and the arc filter 82 is clamped to the inner surface of the adsorption box 6.

[0033] In this embodiment, when the spiral plate 12 rotates, it drives the rotating connecting rod 85 to rotate along the axis of the main shaft 11, and the rotating connecting rod 85 drives the brush roller 86 to rotate in a circle. During the rotation of the brush roller 86, it contacts and rubs with the curved surface of the arc filter 82, thereby scraping off impurities adhering to the arc filter 82, preventing the gas from being difficult to flow into the adsorption box 6 due to clogging of the arc filter 82 by impurities. When the brush roller 86 moves to the bottom of the filter cylinder 1, it contacts the scraping teeth 89 on the support plate 87 and the arc plate 88. The friction force generated 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 filter 82.

[0034] Working principle: The arc filter 82 prevents inorganic impurities that are difficult to be adsorbed by activated carbon from entering the adsorption box 6, and the spiral plate 12 drives the rotating connecting rod 85 and the brush roller 86 to rotate in a circle and sweep away the inorganic impurities adhered to the arc filter 82. The impurities fall into the gap of the brush roller 86 and move with the brush roller 86. When the brush roller 86 contacts the scraper teeth 89, the impurities are shaken off from the gap of the brush roller 86, allowing the gas to flow smoothly between the filter cartridge 1 and the adsorption box 6.

[0035] See also Figures 1-8 On the basis of the above embodiment, in another embodiment of the present invention, the dirt discharge device 9 includes a trapezoidal drainage channel 91, which is fixedly connected to the lower surface of the filter cartridge 1. The filter cartridge 1 is used to receive impurities falling from the arc plate 88 and transport the impurities to the right end through the inclined surface. The right side of the filter cartridge 1 is hinged with a cover plate 92, and a torsion rod 93 is hinged to the inner surface of the support plate 87. A torsion spring is provided at the hinge between the torsion rod 93 and the support plate 87, and the torsion spring provides a rotational reset force for the torsion rod 93.

[0036] In this embodiment, the impurities caught by the scraper 89 fall onto the curved plate 88, and then fall downward from the through groove opened on the curved plate 88 to the trapezoidal drainage channel 91. The impurities then slide to the right along the inclined surface 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, thereby improving the impurity cleaning efficiency and preventing impurities from accumulating inside the device for a long time and affecting the operation of the device.

[0037] 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. The circumferential surface of the torsion rod 93 is fixedly connected with an arc-shaped knocking plate 95. The arc-shaped knocking plate 95 is used to knock on the inner wall of the trapezoidal sewage channel 91 to make impurities adhering to the inner wall of the trapezoidal sewage channel 91 fall off. The toggle plate 96 is fixedly connected to the circumferential surface of the right end of the rotating connecting rod 85. The torsion plate 97 is fixedly connected to the circumferential surface of the right end of the torsion rod 93. The arc-shaped knocking plate 95 abuts against the front side surface of the inner wall of the trapezoidal sewage channel 91, and the front side surface of the toggle plate 96 abuts against the rear side surface of the torsion plate 97.

[0038] In this embodiment, the rotating connecting rod 85 drives the toggle plate 96 to rotate in a circle. When the toggle plate 96 rotates to the bottom of the filter cartridge 1, it contacts the torsion plate 97. The toggle plate 96 pushes the torsion plate 97 to rotate a moving angle, and then the toggle plate 96 continues to rotate upward away from the torsion plate 97. The torsion plate 97 drives the torsion rod 93 and the arc-shaped knocking plate 95 to rotate a certain angle. When the toggle plate 96 is 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 knocking plate 95 to reset rapidly and hit the inner wall of the trapezoidal sewage channel 91, causing vibration between the arc-shaped knocking plate 95 and the inner wall of the trapezoidal sewage channel 91, causing impurities adhering to the inner wall of the trapezoidal sewage channel 91 to fall off quickly, thereby improving the impurity collection effect.

[0039] Working principle: Inorganic impurities fall downward into the trapezoidal sewage channel 91 and are quickly collected, making it convenient for staff to clean up. The toggle plate 96 toggles the twisting plate 97 to rotate the twisting plate 97, and then the toggle plate 96 is driven by the rotating connecting rod 85 to rotate away from the twisting 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 knocking plate 95 to knock on the inner wall of the trapezoidal sewage channel 91 to make the remaining inorganic impurities adhering to the inner wall fall and gather, further improving the cleaning efficiency.
