Description

Technical Field

[0001] This invention relates to the field of compressor technology, and in particular to a novel self-cleaning filter device for purifying compressors. Background Technology

[0002] The CO2 gas used in alkali production is calcining furnace gas, and the CO2 usually contains alkali ash.

[0003] The CO2 compressor inlet has a 200-mesh filter screen, which is frequently clogged, especially in compressors that pump gas in the middle section. Clogging by alkali ash is particularly frequent. Once clogged, it will cause a decrease in the compressor's pumping volume and a large pressure difference at the inlet filter. The large pressure difference will cause the inlet filter to be compressed and deformed. Severe damage may cause the filter screen to be drawn into the cylinder and damage the compressor rotor. Stopping and cleaning not only affects production, but also makes cleaning very difficult. Current technology lacks an automatic cleaning alkali ash filter device. Summary of the Invention

The rotating frame is used to restrict the support shaft; the support shaft is used to provide support when the scraper is working; the magnet and the rotating frame repel each other, so the rotating frame is subjected to gravity and magnetic repulsion, maintaining a fixed angle with the vertical direction. At this time, the rotating frame makes the support shaft located diagonally above the scraper. When the filter screen rotates, it will drive the support shaft to move through friction, thereby driving the rotating frame to rotate in the direction of the magnet. However, at this time, the repulsive force between the magnet and the rotating frame increases, so the rotating frame stabilizes in a new position. At this time, the support shaft just clamps the filter screen with the blade of the scraper.

[0011] Optionally, the self-cleaning component includes a support cover, a scraper, and support columns; the support cover is fixedly connected to the left side of the lower surface of the filter frame, and the support cover has a movable hole; the scraper is rotatably connected to the support cover, and the surface of the scraper is rough; several support columns are fixedly connected to the L-shaped part, and the support columns and movable holes correspond one-to-one; the scraper is used to remove the alkaline dust accumulated on the scraper blade; the support columns are used to hold the scraper in place.

[0015] The beneficial effects of the present invention are: the novel self-cleaning filter device for purification compressors of the present invention, through reasonable structural design, enables the device to filter alkali ash while performing self-cleaning.

[0016] The filter rotation system uses the air pressure difference generated when the filter becomes clogged to drive the rotating component to slide relative to the sliding component. When the air pressure difference decreases, the sliding component resets the rotating component, and the sliding component then converts the sliding into the rotation of the filter, allowing the filter to be scraped and cleaned by the system.

[0017] The friction block, spring, and cylindrical connector work together to make the rotating component move to the right when the pressure difference between the left and right sides of the filter screen reaches a certain value, and the rotating component resets when the pressure difference decreases to a certain value.

[0018] The spray cleaning system uses a steam-water separator to produce water for cleaning, saving water resources by eliminating the need for an external water source.

[0019] The rubber sheet serves three purposes. First, it covers the gap between the filter and the scraper. When the filter is not under airflow, it adheres tightly to the scraper. However, due to the filter's elasticity, airflow deforms it, causing the contact area between the filter and the scraper to shift to the right, creating a gap. Airflow blows through this gap towards the first baffle, where alkali ash accumulates in the first nozzle, causing blockage. The rubber sheet, pressed against the filter by the airflow, effectively seals this gap. Second, it protects the scraper's blade. Alkali ash in the airflow impacts the blade, causing micro-scratches and reducing its lifespan. The rubber sheet effectively blocks this impact. Third, it prevents alkali ash from accumulating on the scraper's blade. Accumulated alkali ash reduces the blade's angle, dulling it and weakening the scraping effect. The rubber sheet prevents this accumulation. Attached Figure Description

Detailed Implementation

[0030] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0031] Example 1

[0032] A novel self-cleaning filter device for a purification compressor, such as Figure 1-9 As shown, it includes a left connector 1, a right connector 2, a filter screen rotation system, a scraping system, and a spray cleaning system; the left connector 1 is connected to the filter screen rotation system; the filter screen rotation system is connected to the scraping system; the filter screen rotation system is connected to the spray cleaning system; the spray cleaning system is connected to the right connector 2.

[0033] The gas to be filtered enters the filter rotation system from the left connector 1. The alkaline dust carried in the gas is filtered by the filter rotation system. The remaining gas enters the spray cleaning system for dehydration. The dehydrated gas is sent to the CO2 compressor. The separated water is temporarily stored in the spray cleaning system. When there is too much alkaline dust in the filter rotation system, the filter rotation system is cleaned by the scraping system. At the same time, the spray cleaning system uses the temporarily stored water to assist in cleaning the filter rotation system.

[0034] The filter rotation system includes a sliding component and a rotating component; the left connector 1 is connected to the sliding component; the sliding component is connected to the rotating component; the sliding component is connected to the spray cleaning system; the rotating component is connected to the scraping system; and the rotating component is connected to the spray cleaning system.

[0035] The sliding assembly includes a square air passage 101, a slide rail 102, a friction block 103, a rack 104, a spring 105, and an L-shaped component 106; the left connector 1 is connected to the left square air passage 101; the square air passage 101 is fixedly connected to two slide rails 102 distributed front and rear; the right ends of the two slide rails 102 are fixedly connected to the right square air passage 101; each of the two slide rails 102 has a friction block 103 fixedly connected to its opposite side; a rack 104 is fixedly connected to the upper inner surface and the lower inner surface of the slide rail 102, and the two racks 104 are staggered; a spring 105 is fixedly connected to the left inner surface of the slide rail 102; and an L-shaped component 106 is fixedly connected to the bottom surface of the left square air passage 101.

[0036] The rotating assembly includes a filter frame 111, a sliding block 112, a cylindrical connector 113, a shield 114, a rotating component 116, a half gear 117, a connecting shaft 118, and a filter screen 119; two square air passages 101 are slidably connected to the filter frame 111; a sliding block 112 is fixedly connected to the middle of the front surface and the middle of the rear surface of the filter frame 111, and the sliding block 112 slides in the corresponding slide rail 102; a cylindrical connector 113 is fixedly connected to the right end of the opposite side of the two sliding blocks 112, and the cylindrical connector 113 is fixedly connected to the spring 105; a shield 114 is fixedly connected to the lower part of the filter frame 111, and a water leakage slit 114a is opened at the lower end of the shield 114, and the shield 114 is connected to the spray cleaning system; a rotating component 116 is rotatably connected to the front side plate and the rear side plate of the filter frame 111, respectively. Two rotating components 116 are respectively fixedly connected to a half gear 117 on opposite sides, and the half gear 117 meshes with the rack 104. The half gear 117 does not simultaneously mesh with the upper rack 104 and the lower rack 104. The two rotating components 116 are connected by a connecting shaft 118, and the axes of the two rotating components 116 and the connecting shaft 118 coincide. A filter screen 119 is fixedly connected between the two rotating components 116. When the rotating assembly slides to the right, the upper rack 104 and the half gear 117 mesh, causing the rotating component 116 to rotate counterclockwise in the direction viewed from front to back. In turn, the rotating component 116 drives the filter screen 119 to rotate. When the rotating assembly returns to its original position, the lower rack 104 and the half gear 117 mesh, causing the rotating component 116 to rotate counterclockwise in the direction viewed from front to back. Therefore, the rotation direction of the filter screen 119 remains unchanged throughout the entire process.

[0037] The filter screen 119 is made of stainless steel, which makes it corrosion resistant and washable.

[0038] The rotating assembly also includes a rubber sealing element 115; the lower end of the shield 114 is fixedly connected to the rubber sealing element 115, and the rubber sealing element 115 surrounds the leakage seam 114a; when the rotating assembly is in its original position, the leakage seam 114a is blocked by the L-shaped element 106, but there is a small gap between the lower end of the shield 114 and the L-shaped element 106, and the rubber sealing element 115 is used to block the above-mentioned small gap to improve the sealing effect.

[0039] The scraping system includes a scraping component and a self-cleaning component; the rotating component is connected to the scraping component; the rotating component is connected to the self-cleaning component.

[0040] The scraping assembly includes a scraper 201, a rubber sheet 202, a rotating frame 203, a support shaft 204, and a magnet 205. The scraper 201 is fixedly connected to the upper left side of the shielding cover 114, and the scraper 201 is tangent to the filter screen 119. The rubber sheet 202 is fixedly connected to the outer side of the scraper 201 blade. The rotating frame 203 is rotatably connected to the connecting shaft 118. The support shaft 204 is rotatably connected to the rotating frame 203, and the support shaft 204 is located on the inner surface of the filter screen 119. The support shaft 204 and the scraper 201 blade clamp the filter screen 119, and the support shaft 204 is made of iron. Two magnets are fixedly connected to the connecting shaft 118. 205; Magnet 205 and rotating frame 203 repel each other, so rotating frame 203 is subjected to gravity and the repulsive force of magnet 205, maintaining a fixed angle with the vertical direction. At this time, rotating frame 203 makes support shaft 204 located diagonally above scraper 201. When filter screen 119 rotates, it will drive support shaft 204 to move through friction, thereby driving rotating frame 203 to rotate in the direction of magnet 205. However, at this time, the repulsive force between magnet 205 and rotating frame 203 increases, so rotating frame 203 stabilizes in a new position. At this time, support shaft 204 just clamps filter screen 119 with the blade of scraper 201.

[0041] The self-cleaning component includes a support cover 211, a scraping fan 212, and a support column 213. The support cover 211 is fixedly connected to the left side of the lower surface of the filter frame 111, and the support cover 211 has a moving hole 211a. The support cover 211 is rotatably connected to the scraping fan 212, and the surface of the scraping fan 212 is rough. Several support columns 213 are fixedly connected to the L-shaped part 106, and the support columns 213 and the moving holes 211a correspond one-to-one. When the rotating component is in its original position, the support column 213 passes through the moving hole 211a and abuts against the scraping fan 212. At this time, the scraping fan 212 does not rotate. When the rotating component slides, the scraping fan 212 disengages from the support column 213 and rotates. At this time, the rotating scraping fan 212 scrapes away the alkali ash accumulated on the blade of the scraper 201.

[0042] The spray cleaning system includes a water intake component and a spray component; the square air duct 101 on the right is connected to the water intake component; the square air duct 101 on the right and the rotating component are connected to the spray component; the water intake component and the spray component are connected.

[0043] The water intake assembly includes a steam-water separator 301, a first water supply pipe 302, a micro pump 303, and an electric valve 304; the square air passage 101 on the right side is connected to the steam-water separator 301; the electric valve 304 is installed at the lower end of the steam-water separator 301, and the electric valve 304 has a first outlet 304a and a second outlet 304b; the electric valve 304 is connected to the micro pump 303 through the first outlet 304a; the lower end of the micro pump 303 is connected to the first water supply pipe 302; the first water supply pipe 302 is connected to the spraying assembly; the right end of the steam-water separator 301 is connected to the right connector 2.

[0044] The spraying assembly includes a water pump 311, a second water supply pipe 312, a water distribution pipe 313, a first nozzle 314, a second nozzle 315, a first baffle 316, and a second baffle 317. The water pump 311 is fixedly connected to the lower surface of the square air passage 101 on the right side, and the water pump 311 is connected to the first water supply pipe 302. The water pump 311 is connected to the second water supply pipe 312. The second water supply pipe 312 is connected to the water distribution pipe 313. The water distribution pipe 313 is connected to a plurality of first nozzles 314. A plurality of second nozzles 315 are fixedly connected to the side wall of the water distribution pipe 313, and the second nozzles 315 pass through the water distribution pipe 313. The shield 114 is fixedly connected to the first baffle 316, and a small hole is opened below the first baffle 316. The rotating frame 203 is fixedly connected to the second baffle 317, and the first baffle 316 and the second baffle 317 are in close contact with the filter screen 119.

[0045] The novel self-cleaning filter device for the purification compressor of this invention is installed before the air inlet of the compressor. During normal operation, gas enters from the left connector 1, passes through the square air passage 101 on the left, and the alkaline ash in the gas is filtered by the filter screen 119 in the filter frame 111. The filtered gas is sent out from the square air passage 101 on the right and enters the gas-water separator 301. The gas with the moisture removed flows out from the right connector 2 and enters the compressor. The separated water flows out from the first outlet 304a of the electric valve 304 and is pressurized by the micro pump 303. The water enters the water pump component 311 through the first water supply pipe 302. After the water pump component 311 has temporarily stored a certain amount of water, the micro pump 303 is turned off, the electric valve 304 is turned on, the first outlet 304a is closed, and the second outlet 304b is opened, and the water flows out from the second outlet 304b.

[0046] When filter screen 119 is not clogged, the self-cleaning filter device of the new purification compressor is in its initial position. At this time, the cylindrical connector 113 is pulled to the left by the spring 105, and at the same time, the top of the cylindrical connector 113 abuts against the friction block 103. Therefore, the cylindrical connector 113 is subjected to a static friction force to the right. The static friction force and the pulling force provided by the spring 105 are balanced, and filter screen 119 continues to work. Alkali ash accumulates on the left side of filter screen 119, causing the mesh of filter screen 119 to become clogged. However, the compressor continues to run, forming a negative pressure on the right side of filter screen 119, thus the filter screen 119 is subjected to pressure to the right. This pressure slowly increases. When the pressure equals the tension provided by spring 105, the static friction force on the cylindrical connector 113 is zero. When the pressure continues to increase and equals twice the tension provided by spring 105, the cylindrical connector 113 experiences a static friction force to the left, reaching its maximum. When the pressure continues to increase, exceeding the sum of the elastic force and the static friction force, the pressure pushes the filter screen 119 to the right, thereby causing the entire rotating assembly to move to the right. At this point, the cylindrical connector 113 disengages from the friction block 103, and the half gear 117 moves to the right, meshing with the rack 104 above, causing the half gear 117 to rotate as viewed from front to back. The direction is rotated counterclockwise. Half gear 117 drives rotating component 116 to rotate, and rotating component 116 drives filter screen 119 to rotate. The rotating assembly continues to move to the right. While filter screen 119 is rotating, the scraping system and spray cleaning system clean filter screen 119, so the mesh of filter screen 119 is unblocked, the pressure difference between the left and right sides of filter screen 119 decreases, and the pressure on filter screen 119 decreases. Spring 105 extends during the rightward movement of the rotating assembly, and the tension of spring 105 on cylindrical connector 113 increases. Finally, the rotating assembly stops moving to the right and then moves to the left under the elastic force of spring 105. When the rotating assembly stops moving to the right, half gear 117... 7. After rotating 180 degrees, the lower end of the half gear 117 meshes with the rack 104 below. When the rotating assembly moves to the left, the rack 104 below causes the half gear 117 to rotate counterclockwise in the direction viewed from front to back, and the filter screen 119 continues to be cleaned. The rotating assembly moves to the left until the cylindrical connector 113 comes into contact with the friction block 103 again. The friction between the cylindrical connector 113 and the friction block 103 forces the rotating assembly to stop moving. It is worth noting that the coefficient of friction of the cylindrical connector 113 relative to the friction block 103 when it moves to the right is less than the coefficient of friction of the cylindrical connector 113 relative to the friction block 103 when it moves to the left.

[0047] When the filter screen 119 is filtering normally, the airflow blows from the left side of the filter screen 119 to the right side. This airflow blows the rubber sheet 202 towards the filter screen 119, causing the rubber sheet 202 to adhere tightly to the scraper 201 and the filter screen 119. The rubber sheet 202 has three functions: first, it covers the gap between the filter screen 119 and the scraper 201. When the filter screen 119 is not affected by the airflow, it adheres tightly to the scraper 201. Due to the elasticity of the filter screen 119, the airflow will deform the filter screen 119, causing the contact area between the filter screen 119 and the scraper 201 to shift to the right, thus forming a gap between the filter screen 119 and the scraper 201. The airflow blows from the gap towards the first baffle 316, and the alkali ash will deposit in the first nozzle 314, causing the first nozzle 316 to... 4. Blockage: The rubber sheet 202, blown by the airflow, presses against the filter screen 119, effectively sealing the gap. Secondly, it protects the blade of the scraper 201. Alkali dust in the airflow can impact the blade of the scraper 201, causing micro-scratches and reducing its lifespan. The rubber sheet 202 covering the scraper 201 effectively blocks the impact of alkali dust. Thirdly, it prevents alkali dust from accumulating on the blade of the scraper 201. When alkali dust accumulates on the blade, the blade angle increases, making the blade dull and reducing the scraping effect. The rubber sheet 202 covering the scraper 201 prevents the accumulation of alkali dust on its blade.

[0048] The rubber sheet 202 is blown by the airflow and sticks to the filter screen 119. The alkali dust will accumulate at the connection between the filter screen 119 and the rubber sheet 202, so the rubber sheet 202 will stick to the filter screen 119. When the filter screen 119 rotates, it will drive the rubber sheet 202 to move. The connection between the filter screen 119 and the rubber sheet 202 moves towards the blade of the scraper 201. The scraper 201 first cuts the alkali dust at the connection between the filter screen 119 and the rubber sheet 202, and then scrapes off the alkali dust on the filter screen 119.

[0049] Because the filter screen 119 has a certain degree of elasticity, when the scraper 201 scrapes off the alkaline ash on the surface of the filter screen 119, the filter screen 119 will slide past the right side of the scraper 201, reducing the scraping effect. Therefore, the support shaft 204 is needed to prevent the filter screen 119 from deforming. The magnet 205 and the rotating frame 203 repel each other, so the rotating frame 203 is subjected to the action of gravity and the repulsive force of the magnet 205, maintaining a fixed angle with the vertical direction. At this time, the rotating frame 203 makes the support shaft 204 located diagonally above the scraper 201. When the filter screen 119 rotates, it will drive the support shaft 204 to move through friction, thereby driving the rotating frame 203 to rotate in the direction of the magnet 205. However, at this time, the repulsive force between the magnet 205 and the rotating frame 203 increases, so the rotating frame 203 stabilizes in a new position. At this time, the support shaft 204 just abuts against the filter screen 119, so that the filter screen 119 will not deform when the scraper 201 scrapes off the alkaline ash.

[0050] While scraping off the alkali ash, the air compressor is still working, so there will be an airflow from left to right that presses the alkali ash near the blade of the scraper 201. The accumulation of alkali ash affects the scraping effect of the blade on the one hand, and on the other hand, it will be blown back onto the filter screen 119 by the airflow. Therefore, the self-cleaning component is needed to scrape off the alkali ash adhering to the scraper 201.

[0051] When the rotating assembly is in its original position, the support column 213 passes through the moving hole 211a and enters the interior of the support cover 211, abutting against the scraper 212. At this time, the airflow from left to right impacts the scraper 212, causing it to tend to rotate clockwise when viewed from front to back. However, because the support column 213 abuts against the lower end of the scraper 212, the scraper 212 remains stationary. At this time, the uppermost part of the scraper 212 will not be higher than the blade of the scraper 201 to avoid obstructing airflow. When the rotating assembly moves, the support column 213 disengages from the scraper 212, and the scraper 212 rotates clockwise when viewed from front to back, removing the airflow. Car 212 first moves the rubber sheet 202 separated from the filter screen 119. The rubber sheet 202 strikes the middle of the scraper 201 downwards, shaking off the alkaline dust on the rubber sheet 202. Then, the scraper fan 212 scrapes off the alkaline dust accumulated on the blade of the scraper 201. The alkaline dust is transferred to the scraper fan 212. The scraper fan 212 continues to rotate and collides with the lower end of the support cover 211, transferring the alkaline dust on the scraper fan 212 to the lower end of the support cover 211. The cleaned scraper fan 212 continues to rotate, removing the alkaline dust on the scraper 201, until the rotating component returns to its original position and the support column 213 abuts against the scraper fan 212 again.

[0052] To improve the scraping effect, the spray cleaning system sprays water to assist in cleaning the filter screen 119, starts the water pump 311, pumps water into the second water supply pipe 312, and then the water enters the water distribution pipe 313, and is sprayed out from the first nozzle 314 and the second nozzle 315.

[0053] The filter frame 111, shield 114, scraper 201, rotating frame 203, support shaft 204, first baffle 316 and second baffle 317 form a receiving space for temporarily storing water used for cleaning. Water is sprayed from the first nozzle 314 and enters the receiving space. Although there is a small hole below the first baffle 316, and water will flow out of the small hole, the water flow rate of the first nozzle 314 is much greater than the water leaking out of the small hole, so the water gradually fills the receiving space. Then, water flows out from between the scraper 201 and the support shaft 204, wetting the scraper 201 and assisting in scraping off the alkali ash. This part of the water will flow down along the left side of the scraper 201, pass through the rubber sheet 202, and flow down along the left side of the shield 114 until it drips outside the device. On the other hand, due to the rotation of the filter screen 119, the support shaft 204 will be rotated. The support shaft 204 is first wetted, and then rotates and squeezes the alkali ash accumulated on the filter screen 119. The alkali ash is loosened under the action of water and squeezing.

[0054] The scraper 201 only scrapes off the alkali ash located on the outside of the filter screen 119. The alkali ash accumulated in the mesh of the filter screen 119 is first moistened and loosened by the support shaft 204. Then, as the filter screen 119 enters the receiving space composed of the filter frame 111, the shield 114, the scraper 201, the rotating frame 203, the support shaft 204, the first baffle 316, and the second baffle 317, it is soaked in water in the space. Most of the alkali ash accumulated on the mesh of the filter screen 119 dissolves. 9 continues to rotate, passing through the junction of the first baffle 316 and the second baffle 317 and leaving the space. At this time, the first baffle 316 and the second baffle 317 also serve to scrape the filter screen 119. The filter screen 119 leaving the space is rinsed again by the water flow sprayed from the second nozzle 315, making the filter screen 119 cleaner. When the spray cleaning system stops working, the water in the space leaks out from the small hole of the first baffle 316 and flows out to the outside through the water leakage seam 114a.

[0055] When the rotating assembly is in the initial position, the L-shaped part 106 is below the water leakage seam 114a. The gap between the shield 114 and the L-shaped part 106 is sealed by the rubber sealing part 115, so the external airflow will not enter the present invention through the water leakage seam 114a.

[0056] It is worth noting that during the cleaning process of filter screen 119, airflow continuously passes through the self-cleaning filter of the purification compressor. During the cleaning process, some alkaline water will inevitably be carried away by the airflow. This water will be separated by the air-water separator 301. However, this water is no longer suitable for cleaning. Therefore, at this time, the first outlet 304a of the electric valve 304 is closed, and water flows out from the second outlet 304b. After the entire cleaning process is completed, the first outlet 304a is opened again to inject water into the pump water component 311.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
