Description

Technical Field

[0001] This invention relates to the technical field of adsorption filtration, and more specifically to a composite filtration device that integrates filtration and adsorption. Background Technology

[0002] This composite filtration device integrates filtration and adsorption. It first filters the air through a filter screen to intercept solid impurities such as dust, particulate matter, and lint. Then, the filtered air comes into contact with water or a liquid medium. The liquid medium washes, adsorbs, and purifies the air by washing and adsorbing odors, harmful gases, and soluble pollutants, thus achieving air purification. It is often used in scenarios such as fresh air purification, workshop exhaust gas treatment, and indoor air deodorization and dust removal.

[0003] Chinese patent document CN201768449U discloses a water-washing air purification device, including a housing with a water storage chamber at the bottom connected to an external circulating water pipe. An air inlet is located on the housing above the water storage chamber, and an air outlet is located at the top of the housing. The air inlet is recessed inside the housing. A spray head is located inside the housing above the air inlet and connected to the external circulating water pipe. An electrodeless lamp is located above the spray head, with a photocatalyst layer coated around its tube. An exhaust fan is located above the electrodeless lamp. A funnel is located below the spray head, positioned on the inner wall of the housing outside the air inlet. The photocatalyst layer is a nano-sized titanium dioxide active material coating. A water mist filter layer is also provided on the inner wall of the housing between the spray head and the electrodeless lamp. A dust filter is installed inside the air inlet. When the device is working, external air enters the inner cavity of the housing through the air inlet on the housing. The dust filter inside the air inlet intercepts particulate matter in the incoming air. The air filtered by the dust filter then enters the water washing process for purification.

[0004] However, the following problems still exist in this solution: during the continuous filtration process, impurities in the air will be continuously intercepted and attached to the filter screen. As the filtration time goes by, the amount of intercepted and accumulated impurities gradually increases, which will continuously cover the filter area and block the mesh pores, causing the pressure drop and operating resistance of the air passing through the filter screen to increase sharply, significantly reducing the air permeability and ventilation performance of the filter screen, and ultimately causing a decrease in filtration efficiency and overall purification effect. Summary of the Invention

[0005] This invention provides a composite filtration device that integrates filtration and adsorption, aiming to solve the problem in related technologies where impurities easily accumulate and clog the filter screen, leading to increased equipment operating resistance and reduced filtration efficiency and purification effect.

[0006] The present invention provides a composite filtration device integrating filtration and adsorption, comprising a housing and a filter cylinder horizontally disposed within the housing. The housing contains an air inlet pipe, a collection frame, a cleaning scraper, a drive mechanism, and a control mechanism. The air inlet pipe is connected to the interior of the filter cylinder. The cleaning scraper is slidably mounted inside the filter cylinder along its axial direction, with its outer wall slidingly abutting against the inner wall of the filter cylinder. The drive mechanism is connected to the cleaning scraper in a transmission manner. The collection frame is located below the end of the filter cylinder. A discharge port is provided at the bottom of the filter cylinder corresponding to the collection frame. The control mechanism is mounted on the filter cylinder and used to control the opening and closing of the discharge port. The drive mechanism drives the cleaning scraper to move axially to scrape away impurities adhering to the inner wall of the filter cylinder. When the cleaning scraper moves to the end of the filter cylinder, the cleaning scraper and the control mechanism cooperate to open the discharge port, and the scraped impurities fall into the collection frame below for centralized collection.

[0007] Its effect lies in the fact that, through the coordinated operation of the cleaning scraper, control mechanism, and collection frame, the filter cartridge continuously possesses self-cleaning capability. Specifically, the drive mechanism moves the cleaning scraper inside the filter cartridge, scraping away the accumulated dust and impurities adhering to the inner wall of the filter cartridge as it moves. As the cleaning scraper moves, it pushes the impurities. When the cleaning scraper moves to the control block, it moves the control block to open the discharge port. Finally, the impurities are discharged through the discharge port and collected by the collection frame, thus preventing the filter pores of the filter cartridge from being covered and blocked by particulate matter for a long time. This keeps the airflow resistance of the filtered airflow low, which is conducive to maintaining the ventilation stability of the device during long-term operation, thereby ensuring the stability of filtration efficiency and purification treatment.

[0008] Preferably, the drive mechanism includes a drive motor and a drive screw. A mounting bracket for mounting the filter cartridge is provided inside the housing, and the drive motor is fixedly mounted on the mounting bracket. The drive screw is coaxially rotatably inserted inside the filter cartridge, passes through the cleaning scraper and engages with it through a threaded drive. The output end of the drive motor is connected to the drive screw.

[0009] Its effect is that by using the drive motor to drive the rotation of the drive screw, the rotational motion can be converted into the axial movement trajectory of the cleaning scraper, so that the cleaning structure can move stably along the inside of the filter cartridge, reducing the need for manual disassembly and cleaning, while facilitating the removal of impurities and ensuring that the filter cartridge maintains good filtration performance.

[0010] Preferably, the control mechanism includes: a control block and a first elastic element; the control block is axially slidably assembled inside the filter cylinder, and its outer side is slidably attached to the inner wall of the filter cylinder; the first elastic element is located on the side of the control block away from the cleaning scraper, and its two ends are respectively connected to the filter cylinder and the control block, and the first elastic element is used to drive the control block to slide to the position of the discharge port so as to close the discharge port.

[0011] Its effect is that the control block can maintain the normally closed state of the discharge port under the action of the first elastic element, so that the internal airflow in the filtration stage is not easy to leak from the discharge area. In the cleaning stage, it can be pushed by the cleaning scraper to form a temporary discharge channel, so that the device can take into account both the filtration sealing and the convenience of discharge.

[0012] Preferably, the drive screw passes through the control block, and a scraper is provided on the side of the control block near the cleaning scraper; a rotating sleeve is provided at the end of the scraper near the drive screw, the rotating sleeve is sleeved on the outside of the drive screw, and is axially slidably assembled on the drive screw; the rotating sleeve is rotatably connected to the control block.

[0013] Its effect is that the scraper can disperse and guide the impurities pushed by the scraper during the movement, and form a rotating guide effect under the drive screw rotation, reducing the accumulation and stagnation of impurities in the discharge area, and making it easier for impurities to move towards the discharge port.

[0014] Preferably, the mounting bracket is slidably assembled inside the housing; a pusher is provided inside the housing, and the output end of the pusher is connected to the mounting bracket; a guide sleeve is fitted on the outside of the filter cartridge, and the inside of the guide sleeve is spaced apart from the filter cartridge; a guide opening is provided at the bottom of the guide sleeve, and the guide opening is arranged at intervals with the filter cartridge in the vertical direction.

[0015] Its effect is that the filtered gas is constrained to the treatment liquid area for discharge under the limiting action of the guide sleeve, which can prolong the flow path of the gas in the liquid medium and enhance the gas-liquid contact. At the same time, the lifting structure of the mounting frame also makes it easy to adjust the position of the filter cartridge according to the working conditions.

[0016] Preferably, the collection frame is horizontally slidably assembled inside the housing, and the sliding direction of the collection frame is parallel to the drive screw. A second elastic element is provided between the collection frame and the housing, which is used to drive the collection frame to move below the discharge port. A clearance frame is provided on the side of the collection frame, and a guide slope is provided on the clearance frame. A top rod is provided on the upper edge of the mounting frame, and the lower end of the top rod is located below the filter cylinder. The top rod and the guide slope are vertically aligned. When the mounting frame moves downward, the top rod and the guide slope cooperate to drive the collection frame to move and make clearance.

[0017] Its effect is that the collection frame can actively offset and avoid structural interference when the filter components move down during the descent of the mounting frame. After the mechanism is reset, it can return to the area below the impurity discharge area, providing corresponding space for subsequent impurity reception and improving the overall coordination of the machine operation.

[0018] Preferably, the intake pipe includes a sliding part and a fixed part. The fixed part is connected to the housing and one end extends to the outside of the housing. The sliding part is slidably mounted on the fixed part and communicates with the filter cartridge.

[0019] Its effect is that when the filter cartridge moves up or down, the sliding part can synchronously compensate for the movement distance relative to the fixed part, so that the air intake passage remains connected under different height conditions, reducing the risk of pipe pulling, misalignment or blockage caused by structural displacement.

[0020] Preferably, an auxiliary scraping layer is provided on the end face of the cleaning scraper, and scraping teeth are provided on the side of the scraper near the cleaning scraper. The scraping teeth are located at the end of the scraper away from the drive screw, and the scraping teeth cooperate with the auxiliary scraping layer when the scraper rotates.

[0021] Its effect is that the auxiliary scraping layer can enhance the ability to adhere to and clean the fine deposits on the inner wall of the filter cartridge, while the scraping teeth can comb and remove residual impurities on the surface of the auxiliary scraping layer during rotation, reducing the problem of reduced cleaning efficiency caused by repeated adhesion of impurities.

[0022] Preferably, both ends of the filter cartridge are provided with impurity discharge ports; two sets of control mechanisms and two sets of collection frames are provided, respectively arranged at both ends of the filter cartridge.

[0023] Its effect is that after both ends of the filter cartridge have the ability to remove impurities, the cleaning scraper can complete the removal of impurities in the corresponding direction during the reciprocating motion, without the need for impurities to accumulate on one side, which can reduce the local impurity removal load and improve the internal cleaning balance.

[0024] Preferably, the air intake pipe is connected to the filter cartridge at the middle position.

[0025] The effect is that, with the air intake positioned in the middle of the filter cartridge, the cleaning scraper only has a short-term impact on the air intake passage when it passes through the middle area. At other times, the filtered airflow can still enter the filtration area normally, which helps to reduce the impact of the cleaning action on the overall continuity of filtration operation.

[0026] Beneficial effects: By sliding cleaning scrapers, control blocks, and collection frames inside the filter cartridge, this invention can achieve gas filtration, adsorption, and purification as well as automatic slag and impurity removal functions for the filter cartridge. This helps to clean impurities on the inner wall of the filter cartridge, prevent filter pore blockage, and maintain stable filtration performance, thus ensuring gas filtration efficiency and purification effect.

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figures 1 to 9As shown, the composite filtration device integrating filtration and adsorption of the present invention includes a housing 1 and an air inlet pipe 3, a collection frame 4, a cleaning scraper 5, a drive mechanism 6, and a control mechanism 7 installed inside the housing 1. The filter cylinder 2 is horizontally arranged inside the housing 1, that is, the filter cylinder 2 is horizontally mounted inside the housing 1. The air inlet pipe 3 adopts a through-type layout structure, with one end connected to the internal cavity of the filter cylinder 2 to form a connecting passage, and the other end extending outward through the outside of the housing 1, which can introduce the impurity gas to be filtered into the filter cylinder 2 for filtration and purification. The cleaning scraper 5 is slidably mounted axially in the internal cavity of the filter cylinder 2. The outer peripheral wall of the cleaning scraper 5 is in sliding contact with the inner wall of the filter cylinder 2. When the cleaning scraper... When the filter cylinder 5 reciprocates along the axial direction of the filter cylinder 2, it can scrape off dust, particulate matter and other impurities that are attached to and accumulated on the inner wall of the filter cylinder 2. The drive mechanism 6 is connected to the cleaning scraper 5 and can drive the cleaning scraper 5 to reciprocate along the inside of the filter cylinder 2 to achieve the scraping of impurities on the inner wall of the cylinder. The collection frame 4 is arranged below the end of the filter cylinder 2, close to the end of the filter cylinder 2 and facing the bottom area of ​​the filter cylinder 2. The bottom of the filter cylinder 2 and the collection frame 4 are respectively provided with a discharge port 21 for the discharge of impurities. The scraped impurities can be discharged through the discharge port 21 into the collection frame 4 below for centralized collection. At the same time, the control mechanism 7 is installed on the filter cylinder 2 to control the opening and closing of the discharge port 21.

[0039] The bottom area inside the shell 1 is designated as the adsorption zone, which contains a treatment liquid used for gas purification as the adsorption and purification medium. This liquid can dissolve, adsorb, and purify the harmful gases, odors, and gaseous pollutants that flow through it. The filter cartridge 2 is installed above the adsorption zone inside the shell 1. The gas to be treated is introduced into the inner cavity of the filter cartridge 2 through the inlet pipe 3. The gas first passes through the filter cartridge 2 to remove dust, particulate matter, and solid impurities carried in the gas. After preliminary filtration and impurity removal, the gas enters the adsorption zone at the bottom of the shell 1 and comes into full contact with the treatment liquid contained in the adsorption zone. Through the dissolution, adsorption, and neutralization effects of the treatment liquid, the odors and harmful gaseous substances in the gas are subjected to secondary adsorption and purification, thereby realizing a continuous treatment process in which the gas is first filtered and impurity removed, and then adsorbed and purified by the treatment liquid.

[0040] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6When a large amount of impurities accumulate on the inner wall of the filter cylinder 2 during long-term filtration operations, the drive mechanism 6 drives the cleaning scraper 5 to move axially along the filter cylinder 2. Relying on the contact action between the cleaning scraper 5 and the inner wall of the filter cylinder 2, the impurities adhering to the inner wall of the filter cylinder 2 are scraped off. When the cleaning scraper 5 moves to the preset position at the end of the filter cylinder 2, the cleaning scraper 5 can form a mechanical linkage with the control mechanism 7, triggering and opening the impurity discharge port 21 at the bottom of the filter cylinder 2. The impurities that have been scraped off fall smoothly through the impurity discharge port 21 and flow into the collection frame 4 below, completing the automatic centralized collection and cleaning of impurities. This removes impurities from the inner wall of the filter cylinder 2 in real time, continuously ensuring the stable flow capacity, filtration efficiency, and overall purification effect of the medium in the filter cylinder 2.

[0041] Reference Figure 5 , Figure 6 The drive mechanism 6 includes a drive motor 61 and a drive screw 62. A mounting bracket 8 for mounting the filter cartridge 2 is fixedly installed inside the housing 1. The drive motor 61 is fixedly mounted on the mounting bracket 8. The drive screw 62 is coaxially rotatably inserted through the center of the filter cartridge 2, that is, the center line of the drive screw 62 and the center line of the filter cartridge 2 are on the same straight line. The cleaning scraper 5 is fitted outside the drive screw 62 and forms a threaded transmission engagement structure with the drive screw 62 so that the cleaning scraper 5 can be moved when the drive screw 62 rotates. The power output end of the drive motor 61 is connected to the drive screw 62 for transmission.

[0042] When the drive motor 61 is running, it can drive the drive screw 62 to rotate around its own axis. Relying on the helical transmission of the threaded pair, the rotational motion of the drive screw 62 is converted into the linear movement of the cleaning scraper 5, so that the cleaning scraper 5 slides along the axial direction of the drive screw 62 and against the inner wall of the filter cylinder 2, thereby scraping and cleaning the impurities and dirt attached to the inner wall of the filter cylinder 2.

[0043] Reference Figure 5 , Figure 6 The filter cylinder 2 has two discharge ports 21 for discharging impurities at both ends along the axial direction. The two discharge ports 21 are located at both ends of the filter cylinder 2. The control mechanism 7 and the collection frame 4 are each set in two groups and are matched and installed at the left and right ends of the filter cylinder 2 respectively.

[0044] During operation, the drive motor 61 can continuously rotate in both forward and reverse directions. During operation, it drives the drive screw 62 connected to it to rotate synchronously. Through the threaded transmission, it further drives the cleaning scraper 5 to slide axially back and forth along the internal cavity of the filter cylinder 2. During the movement, the cleaning scraper 5 scrapes and pushes the impurities attached to and trapped on the inner wall of the filter cylinder 2. At the same time, it forms a discharge channel based on the pre-set discharge ports 21 at both ends of the filter cylinder 2. When the cleaning scraper 5 pushes the impurities to the discharge port 21, the scraped impurities can be smoothly discharged from the discharge ports 21 at both ends and fall into the corresponding collection frame 4 for centralized collection. In this way, the automatic scraping, rapid discharge and centralized collection of impurities inside the filter cylinder 2 are completed in a coordinated manner, realizing the cleaning of impurities inside the filter cylinder 2.

[0045] Reference Figure 5 , Figure 7 , Figure 9 The air inlet pipe 3 is located in the middle of the filter cylinder 2. When the cleaning scraper 5 moves back and forth along the inner wall of the filter cylinder 2 to scrape and clean the impurities and dirt attached to the cylinder wall, the cleaning scraper 5 will only briefly block and temporarily seal the air inlet of the air inlet pipe 3 when it moves to the interface position opposite to the air inlet pipe 3. During the time period when the cleaning scraper 5 is in any other moving position, the external impurity gas can normally enter the interior of the filter cylinder 2 through the air inlet pipe 3, and the gas-solid separation and impurity filtration are completed by the filter cylinder 2 itself. The entire scraping and cleaning process will not block or interfere with the continuous air intake and normal filtration operation of the filter cylinder 2. It can achieve automatic slag and dirt removal while ensuring continuous operation of the filtration condition.

[0046] Reference Figure 5 , Figure 6 , Figure 7 The control mechanism 7 includes a control block 71 and a first elastic element 72. The control block 71 is axially slidably mounted inside the filter cylinder 2 and is located at the end of the filter cylinder 2. The outer wall of the control block 71 and the inner wall of the filter cylinder 2 are in a sliding fit, that is, the control block 71 can slide back and forth along the axial direction of the filter cylinder 2. The first elastic element 72 is located on the side of the control block 71 away from the cleaning scraper 5. The first elastic element 72 is a spring. The two ends of the first elastic element 72 are fixedly connected to the cylinder wall of the filter cylinder 2 and the control block 71, respectively. The control block 71 is driven to slide normally to the position of the discharge port 21 by its own elastic force, thereby sealing the discharge port 21.

[0047] In the initial working state of the equipment, the first elastic element 72 drives the control block 71 to stably fit against the discharge port 21 by its own elastic force, so as to reliably block the discharge port 21 and keep the discharge port 21 closed. When the cleaning scraper 5 moves along the filter cylinder 2 axially to the end position of the filter cylinder 2, the cleaning scraper 5 will cooperate with the control block 71 and push the control block 71 to overcome the elastic force of the first elastic element 72 and move, thereby opening the discharge port 21, providing a smooth channel for the impurities accumulated inside the filter cylinder 2 to be discharged outward through the discharge port 21, which facilitates the subsequent automatic impurity removal operation.

[0048] Reference Figure 5 , Figure 6 , Figure 7 , Figure 8 The drive screw 62 is axially inserted through the control block 71 for assembly and installation, meaning the control block 71 can slide axially relative to the drive screw 62. A scraper 9 is installed on the side of the control block 71 facing the cleaning scraper 5. A rotating sleeve 91 is provided at the end of the scraper 9 near the drive screw 62. The rotating sleeve 91 is rotatably sleeved on the outside of the drive screw 62, allowing it to slide axially along the drive screw 62 and form a rotatable connection with the control block 71. That is, the scraper 9 is rotatably connected to the control block 71 through the rotating sleeve 91.

[0049] When the cleaning scraper 5 moves to the position of the control block 71, the end of the cleaning scraper 5 will come into contact with the scraper 9, and the contact force will push the scraper 9 and the connected control block 71 to move together, thereby adjusting the overall position of the control block 71. During the smooth movement of the control block 71, the scraper 9 will move synchronously, keeping the cleaning scraper 5 and the scraper 9 in close contact. This achieves synchronous movement of the cleaning scraper 5, the scraper 9, and the control block 71. During the synchronous movement of the three, the waste discharge port 21 will gradually... Start; at the same time, under the helical transmission and rotational drive of the drive screw 62, the scraper 9 moves axially along with the rotating sleeve 91 and rotates together with the drive screw 62. On the one hand, it can scrape and peel off the impurities scraped off the filter cylinder 2 by the cleaning scraper 5. On the other hand, relying on the rotational agitation and guiding effect of the scraper 9 itself, it can smoothly transport the peeled impurities to the discharge port 21 and discharge them outward through the discharge port 21, thereby automatically completing the continuous scraping, conveying and overall cleaning of impurities on the filter cylinder 2.

[0050] Reference Figure 8The end section of the drive screw 62 near the control block 71 is not machined with a threaded structure, and a groove 621 is provided on the outer periphery of the end corresponding to the control block 71 along the length of the drive screw 62. The groove 621 is axially arranged. The rotating sleeve 91 is fitted on the outside of the drive screw 62. A slider that slides in cooperation with the groove 621 is provided on the inner side of the rotating sleeve 91. Relying on the axial guiding and limiting effect of the groove 621, the rotating sleeve 91 can move axially relative to the drive screw 62 without being affected by the threaded groove on the drive screw 62.

[0051] Reference Figure 7 An auxiliary scraping layer 51 is provided on the end face of the cleaning scraper 5. The auxiliary scraping layer 51 can be made of rubber or a brush. The auxiliary scraping layer 51 is set in a ring shape and contacts the inner wall of the filter cylinder 2. When the cleaning scraper 5 moves back and forth along the inside of the filter cylinder 2, it can simultaneously drive the auxiliary scraping layer 51 to move along with it. Relying on the flexible adhesion and wiping and scraping action of the auxiliary scraping layer 51, it can effectively scrape off the dust, particles and various impurities that are firmly attached to the inner wall of the filter cylinder 2, greatly improving the overall scraping and cleaning effect of the impurities attached to the inner wall of the filter cylinder 2.

[0052] Reference Figure 6 , Figure 7 , Figure 8 Additionally, a scraper tooth 92 structure is provided on the side of the scraper 9 near the cleaning scraper block 5, and the scraper tooth 92 is arranged at the end of the scraper 9 away from the drive screw 62. When the scraper 9 rotates with the drive structure, the scraper tooth 92 can cooperate with the auxiliary scraper layer 51 on the cleaning scraper block 5. With the combing and scraping action of the scraper tooth 92, the impurities retained and entangled on the auxiliary scraper layer 51 are cleaned and peeled off for a second time, and the impurities are discharged to the outside in time, so as to avoid the accumulation of impurities on the surface of the auxiliary scraper layer 51 and affect the scraping performance. Through the synergistic effect of the scraper tooth 92 and the auxiliary scraper layer 51, the cleaning and purification effect of impurities inside the filter cartridge 2 is improved.

[0053] Reference Figure 1 , Figure 2 , Figure 3 The mounting bracket 8 is slidably mounted inside the housing 1 along the vertical direction. A pusher 81 is fixedly installed inside the housing 1. The pusher 81 is a cylinder. The power output end of the pusher 81 is connected to the mounting bracket 8, which can drive the mounting bracket 8 to move up and down and slide inside the housing 1. A guide sleeve 22 is coaxially sleeved on the outer side of the filter cylinder 2. The inner wall of the guide sleeve 22 and the outer wall of the filter cylinder 2 maintain a fixed distance and form an annular air passage layer. A guide port 221 is opened at the bottom of the guide sleeve 22. The guide port 221 is arranged in a staggered structure with the lower end of the filter cylinder 2 in the vertical height direction.

[0054] During operation, to ensure thorough mixing and contact between the filtered gas and the treatment liquid inside the housing 1, the mounting frame 8 is driven downwards by the pusher 81, simultaneously moving the filter cylinder 2 and the outer guide sleeve 22 mounted on the mounting frame 8 downwards until the lower part of the guide sleeve 22 is completely submerged below the surface of the treatment liquid inside the housing 1, so that the guide port 221 is submerged in the treatment liquid. However, the filter cylinder 2 remains outside the treatment liquid to prevent the treatment liquid from directly entering the interior of the filter cylinder 2. The impurity-laden gas first passes through the filter cylinder 2 to complete impurity filtration and purification. The filtered gas is confined and limited by the guide sleeve 22 and cannot diffuse in all directions. It can only be discharged directionally from the guide port 221, which is submerged in the treatment liquid at the bottom, and directly flow into the interior of the treatment liquid. This effectively extends the contact path and contact time between the gas and the treatment liquid, allowing the gas and the treatment liquid to fully react and contact, greatly improving the overall purification effect of the equipment on the waste gas.

[0055] When deep adsorption purification of gas is required, the guide port 221 at the lower end of the guide sleeve 22 is immersed in the treatment liquid; when deep treatment is not required, the guide sleeve 22 can be removed from the treatment liquid, and can be flexibly switched according to the actual purification conditions.

[0056] Reference Figure 2 , Figure 4 The intake pipe 3 includes a fixed part 32 and a sliding part 31. The fixed part 32 is fixedly installed on the housing 1, with one end extending outward and penetrating to the outside of the housing 1 to form a fixed connecting section of the intake passage. The sliding part 31 is fitted onto the fixed part 32 in a vertically sliding manner and can slide vertically along the fixed part 32. At the same time, the internal channel of the sliding part 31 is connected to the internal cavity of the filter cartridge 2 to ensure smooth airflow.

[0057] When the filter cartridge 2 moves up and down along with the mounting bracket 8, the filter cartridge 2 will synchronously drive the sliding part 31 connected to it to move together, so that the sliding part 31 relative to the fixed part 32 will produce adaptive up and down sliding compensation. Through the sliding cooperation between the sliding part 31 and the fixed part 32, the entire intake pipe 3 can dynamically adapt to the up and down stroke of the filter cartridge 2 and the mounting bracket 8, thereby completely avoiding the problems of position jamming and structural interference that occur during the up and down movement of the intake pipe 3 structure and the mounting bracket 8, and ensuring that the up and down movement of the mounting bracket 8 and the filter cartridge 2 is smooth and unobstructed.

[0058] Reference Figure 1 , Figure 4The collection frame 4 is assembled inside the housing 1 by horizontal sliding, and the overall sliding direction of the collection frame 4 is parallel to the axis of the drive screw 62. A second elastic element 41 is assembled between the collection frame 4 and the inner wall of the housing 1. The second elastic element 41 is set as a spring. Relying on the elastic restoring force of the second elastic element 41, the collection frame 4 can be normally driven to move stably and be kept in the position directly below the discharge port 21. A clearance frame 42 is integrally provided on the side of the collection frame 4. An inclined guide slope 421 is formed on the clearance frame 42. A top rod 82 is vertically fixed on the mounting bracket 8. The lower end of the top rod 82 extends to the lower area of ​​the filter cylinder 2. At the same time, the lower end of the top rod 82 is vertically aligned with the guide slope 421 of the clearance frame 42.

[0059] When the pusher 81 drives the mounting frame 8 to move downwards, the mounting frame 8 will simultaneously drive the push rod 82 to move downwards as well. During the downward movement, the lower end of the push rod 82 gradually forms a sloped contact with the guide slope 421. As the mounting frame 8 and the push rod 82 continue to move downwards, the lower end of the push rod 82 will successively contact and abut against different positions of the guide slope 421. Utilizing the guiding transmission effect of the slope, the collection frame 4 is driven to slide horizontally away from the mounting frame 8. At the same time, the second elastic element 41 is compressed, causing the collection frame 4 to move laterally out from the position directly below the filter cylinder 2 and complete the active relocation. This effectively avoids the problem of structural interference and obstruction of movement caused by the collection frame 4 to the downward movement of the filter cylinder 2 and the mounting frame 8, ensuring that the overall mechanism operates smoothly and reliably.

[0060] Reference Figure 4 , Figure 5 The lowest point of the guide slope 421 and the collection frame 4 are arranged at intervals in the horizontal direction. As the top rod 82 moves downward, the side wall of the top rod 82 will gradually come into contact with and act on the guide slope 421. With the guiding thrust of the slope, the collection frame 4 will be driven to move as a whole. The collection frame 4 will continue to move until the end of the placement frame 42 is tightly against the side of the top rod 82. At this time, the collection frame 4 will stop moving. After the collection frame 4 stops, the whole will form a staggered layout with the filter cylinder 2 in the vertical projection direction. This effectively avoids the problem of structural collision and motion interference between the filter cylinder 2 and the collection frame 4 during the subsequent downward movement of the filter cylinder 2, and ensures that the filter cylinder 2 and the collection frame 4 move smoothly and without affecting each other.

[0061] When the filter cylinder 2 moves downward and reaches the bottom of its stroke, the side of the push rod 82 remains in close contact with the relief frame 42. The limiting support of the push rod 82 and the relief frame 42 prevents the collection frame 4 from interfering with its position during the subsequent upward movement and reset of the filter cylinder 2. After the filter cylinder 2 moves upward and drives the push rod 82 to move upward, the push rod 82 and the relief frame 42 gradually separate and release the limiting constraint. Then, the second elastic element 41 can release its elastic stored force and drive the collection frame 4 to automatically reset to its initial working position, so as to facilitate the subsequent collection and processing of impurities.

[0062] The implementation principle of this invention is as follows: During the deep purification treatment of industrial waste gas and other gases, the lower end of the guide sleeve 22 is always submerged below the liquid surface of the treatment liquid inside the shell 1. The gas to be purified is first transported to the inside of the filter cylinder 2 through the air inlet pipe 3. The filter cylinder 2 completes the interception and filtration of solid particles and impurities. After the preliminary filtration, the gas is then introduced into the treatment liquid below under the guiding and limiting action of the guide sleeve 22, and fully contacts the treatment liquid and undergoes adsorption and other reactions, thereby realizing the all-round adsorption and purification treatment of the gas.

[0063] When prolonged operation of the equipment causes a large amount of dust and impurities to accumulate on the inner wall of the filter cartridge 2, resulting in blockage and a decrease in filtration throughput, the pushing component 81 can drive the mounting frame 8 to move upwards to complete the position reset. Subsequently, the second elastic component 41, relying on its own elastic reset force, drives the collection frame 4 to move synchronously, so that the collection frame 4 moves to a position directly below the impurity discharge port 21 on the side wall of the filter cartridge 2. At the same time, the drive motor 61 outputs power to drive the drive screw 62 to rotate continuously. The rotating drive screw 62 further drives the cleaning scraper 5 to move linearly back and forth along the inner wall of the filter cartridge 2. 5. During the movement, the cleaning scraper 5 scrapes off the attached impurities by closely adhering to the inner wall of the filter cylinder 2, and simultaneously pushes the scraped impurities forward for transport. When the cleaning scraper 5 moves to the position where it abuts against the scraper 9, it can drive the control block 71 to move. The movement of the control block 71 causes the discharge port 21 to gradually open from the closed state. At the same time, the scraper 9 rotates synchronously with the drive screw 62 to guide and comb the impurities pushed to the discharge port 21, so that the scraped impurities can be smoothly discharged outward through the discharge port 21 and finally fall into the collection frame 4 below for centralized collection and storage.

[0064] This invention, by setting cleaning scraper 5, scraper 9, control block 71, etc. inside the filter cylinder 2, can automatically complete the real-time scraping, diversion and collection of impurities attached to the inner wall of the filter cylinder 2, effectively and timely cleaning the blockage inside the filter cylinder 2, avoiding long-term accumulation of impurities that cause filter hole blockage, and continuously ensuring the stable filtration throughput and filtration performance of the filter cylinder 2. At the same time, with the cooperation of the guide sleeve 22, it ensures that the entire gas treatment equipment always maintains stable and efficient gas filtration efficiency and purification effect.
