Description

Technical Field

[0001] This invention relates to the field of zeolite molecular sieve technology, and in particular to a zeolite molecular sieve adsorption-desorption waste gas purification device. Background Technology

[0002] Zeolite molecular sieves are inorganic crystalline materials that play an irreplaceable role in catalysis, adsorption, and ion exchange due to their regular pore structure, strong acidity, and high hydrothermal stability. Adsorption in zeolite molecular sieves is a physical process. The adsorption is primarily caused by "surface forces" generated by molecular attraction on a solid surface. When a fluid flows through, some molecules in the fluid collide with the adsorbent surface due to irregular motion, causing molecular aggregation on the surface. This reduces the number of such molecules in the fluid, achieving separation and removal. Since adsorption does not involve a chemical change, the zeolite molecular sieve regains its adsorption capacity once the aggregated molecules on the surface are removed. This process is the reverse of adsorption and is called desorption or regeneration.

[0003] Patent document CN108392949A discloses a zeolite molecular sieve rotor, comprising: an adsorption chamber, a cooling chamber, and a desorption chamber; the cabinet has a rectangular box structure, and the bottom of the cabinet is welded with six legs arranged in a rectangular array; rectangular inspection ports are provided on the front and rear sides of the cabinet, and a rectangular inspection plate is fixed to the upper part of the inspection port by bolts; a partition plate that looks like a chicken claw when viewed from the side is welded to the upper part of the cabinet, and the adsorption chamber, cooling chamber, and desorption chamber are separated inside the cabinet by the partition plate; a central shaft is embedded in the side walls on the left and right sides of the cabinet through bearings, and two sieve wheels arranged in a linear array are embedded in the cabinet through the central shaft.

[0004] However, in actual use, the inventors found that after a long period of adsorption and desorption of VOCs (volatile organic compounds) by traditional zeolite rotors, blockages would appear in the rotor mesh, thus affecting the normal use of the zeolite rotor. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a zeolite molecular sieve adsorption-desorption waste gas purification device, comprising an adsorption mechanism, a translation mechanism, and a purification mechanism. When blockages occur in the mesh of the zeolite rotor, the translation mechanism moves multiple first and second adsorption disks away from each other. Subsequently, the moving component in the purification mechanism moves the intermittent control component and the crushing component into the gap between the first and second adsorption disks. Driven by the intermittent control component, the crushing component swings back and forth, using a brush to break up the blockages in the rotor mesh. Then, the absorption component absorbs the blockages, thereby cleaning the zeolite rotor. This invention solves the problem of blockages in the existing rotor mesh, which affects the normal use of the zeolite rotor. Furthermore, dividing a single zeolite adsorption disk into multiple independent adsorption disks ensures the cleaning effect of the zeolite rotor.

[0006] To address the above technical problems, the following technical solution is adopted: a zeolite molecular sieve adsorption-desorption waste gas purification device, comprising...

[0007] A purification chamber mechanism, wherein an adsorption mechanism is rotatably mounted on the central shaft of the purification chamber mechanism, the adsorption mechanism includes a cylindrical component disposed inside the purification chamber mechanism, a plurality of adsorption disk assemblies disposed inside the cylindrical component and coaxially arranged, and a separator component connecting the plurality of adsorption disk assemblies.

[0008] A translation mechanism is provided outside the adsorption mechanism and is used to drive multiple adsorption disk assemblies inside the adsorption mechanism to move. The translation mechanism includes a support frame, a drive assembly provided on the support frame, and a connecting rod provided at the lower end of the drive assembly.

[0009] The impurity removal mechanism is located inside the purification chamber and can extend into the adsorption mechanism to crush and adsorb impurities on the adsorption plate assembly. The impurity removal mechanism includes an intermittent control component, a moving component for driving the intermittent control component to enter or exit the cylindrical component, a crushing component connected to the intermittent control component for crushing impurities on the adsorption plate assembly, and an absorption component that cooperates with the intermittent control component for sucking out the crushed impurities.

[0010] Preferably, the adsorption disk assembly includes a first adsorption disk and a second adsorption disk molded from powdered zeolite molecular sieve and arranged alternately, and a protective plate disposed on the outside of the first adsorption disk and the second adsorption disk.

[0011] Preferably, the separating component includes a separating ring disposed on the central rotating shaft and attached to the outside of the first or second adsorption disk, a plurality of separating rods connected to the separating ring, and a separating strip disposed between two adjacent adsorption disks and respectively connected to the separating rods.

[0012] Preferably, the drive assembly includes a first drive unit disposed on the support frame, a cross link connected to the first drive unit and disposed on the support frame, a sliding shaft disposed on the support frame, and a plurality of sliding blocks disposed on the sliding shaft and connected to the cross link.

[0013] Preferably, the sliding block is connected to the protective plate via a connecting rod.

[0014] Preferably, the intermittent control component includes:

[0015] The driving component includes a control housing, a second driving unit disposed inside the control housing, a worm gear connected to the second driving unit, and a worm wheel that cooperates with the worm gear and is rotatably disposed inside the control housing.

[0016] A rotating component, comprising a reduction unit connected to the worm gear, a rotating shaft connected to the reduction unit, and two limiting plates disposed on the rotating shaft;

[0017] The oscillating component includes a cam coaxially arranged with the worm gear, a drive rod disposed outside the cam and connected at the other end to the oscillating rod, and a limiting block hinged to one end of the oscillating rod.

[0018] The deceleration unit and the rotating shaft can slide relative to each other, and the limiting block is engaged between the two limiting plates.

[0019] Preferably, the moving component includes a first telescopic unit for driving the intermittent control component to move and connected to the control box, a second telescopic unit for driving the first telescopic unit to move, and a slide rail adapted to the first telescopic unit.

[0020] Preferably, the crushing assembly includes a plurality of crushing plates fixedly mounted on the rotating shaft and a brush mounted on one side of the crushing plates.

[0021] Preferably, the absorption assembly includes a negative pressure pump disposed on the purification chamber, a negative pressure suction pipe connected to the negative pressure pump, a main suction pipe connected to the negative pressure suction pipe and disposed on the control chamber, a plurality of branch suction pipes connected to the main suction pipe and disposed on the upper end of the crushing plate, and a plurality of suction nozzles disposed on the branch suction pipes.

[0022] The main suction tube is equipped with a filter screen inside for filtering and collecting impurities.

[0023] Preferably, the cylindrical component includes a cylindrical body with an opening and a sliding cover plate that cooperates with the cylindrical body and is used to seal the opening, and a sealing strip is provided on the sliding cover plate.

[0024] The beneficial effects of this invention are:

[0025] (1) In this invention, by setting an adsorption mechanism in conjunction with a translation mechanism and a cleaning mechanism, when blockages appear in the mesh of the zeolite rotor, the translation mechanism drives multiple first adsorption disks and second adsorption disks to move away from each other. Then, the moving component in the cleaning mechanism drives the intermittent control component and the crushing component to enter the gap between the first adsorption disk and the second adsorption disk. Under the drive of the intermittent control component, the crushing component swings back and forth to crush the blockages in the mesh of the rotor using a brush. Then, the absorption component absorbs the blockages, thereby achieving the function of cleaning the zeolite rotor. On the one hand, it solves the problem that blockages appear in the mesh of the existing rotor, thus affecting the normal use of the zeolite rotor. On the other hand, dividing a whole zeolite adsorption disk into multiple independent adsorption disks can ensure the cleaning effect of the zeolite rotor, avoid the situation that the zeolite rotor cannot be completely cleaned due to the zeolite rotor being too thick, and can effectively improve the cleaning efficiency of the zeolite rotor.

[0026] (2) In this invention, the adsorption mechanism includes a cylindrical part, an adsorption disk assembly and a separating component. The adsorption disk assembly is set as multiple independent adsorption disks. A separating component is also provided between the first adsorption disk and the second adsorption disk to divide the adsorption disk assembly into an adsorption zone, a desorption zone and a cooling zone. When using the zeolite rotor for adsorption, multiple first adsorption disks and second adsorption disks can be combined into a whole or used separately. Adsorption can be performed separately by adsorbing multiple first adsorption disks and second adsorption disks, which can prolong the flow time of VOCs inside the zeolite rotor, thereby ensuring that VOCs are completely adsorbed. In actual use, it provides more options for users, making it easier for operators to select the appropriate zeolite rotor speed and the spacing between multiple adsorption disks according to different VOCs, so as to improve the adsorption effect and adsorption efficiency of VOCs.

[0027] (3) In this invention, by setting up a crushing component and an absorption component, after the crushing component and the absorption component complete the absorption and cleaning of the blockage, the brush in the crushing component can be placed in the cleaning bucket inside the purification box for cleaning, so that the brush is always kept clean and the brush is used effectively. At the same time, a collection component for filtering and collecting the blockage is also set inside the main suction pipe in the absorption component. This setting can effectively collect the blockage, prevent the blockage from staying in the absorption component for a long time and causing damage to the absorption component, and also facilitate the centralized treatment of the blockage, making it more practical.

[0028] In summary, this equipment has the advantages of good adsorption effect and easy cleaning, and is especially suitable for the field of zeolite molecular sieve technology. Attached Figure Description

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0049] Example 1

[0050] like Figures 1-4 As shown, a zeolite molecular sieve adsorption-desorption waste gas purification device includes...

[0051] The purification box mechanism 1 has an adsorption mechanism 2 rotatably mounted on its central rotating shaft 11. The adsorption mechanism 2 includes a cylindrical component 21 disposed inside the purification box mechanism 1, a plurality of adsorption disk assemblies 22 disposed inside the cylindrical component 21 and coaxially arranged, and a separating component 23 connecting the plurality of adsorption disk assemblies 22.

[0052] Translation mechanism 3 is disposed outside the adsorption mechanism 2 and is used to drive multiple adsorption disk assemblies 22 inside the adsorption mechanism 2 to move. The translation mechanism 3 includes a support frame 31, a driving assembly 32 disposed on the support frame 31, and a connecting rod 33 disposed at the lower end of the driving assembly 32.

[0053] Impurity removal mechanism 4 is located inside the purification box mechanism 1 and can extend into the adsorption mechanism 2 to crush and adsorb impurities on the adsorption plate assembly 22.

[0054] The impurity removal mechanism 4 includes an intermittent control component 41, a moving component 42 for driving the intermittent control component 41 into or out of the cylindrical component 21, a crushing component 43 connected to the intermittent control component 41 for crushing impurities on the adsorption plate component 22, and an absorption component 44 cooperating with the intermittent control component 41 for sucking out the crushed impurities.

[0055] In this embodiment, by setting up an adsorption mechanism 2 in conjunction with a translation mechanism 3 and a cleaning mechanism 4, when blockages appear in the mesh of the zeolite rotor, the translation mechanism 3 drives multiple first and second adsorption disks to move away from each other. Subsequently, the moving component 42 in the cleaning mechanism 4 drives the intermittent control component 41 and the crushing component 43 to enter the gap between the first and second adsorption disks. Driven by the intermittent control component 41, the crushing component 43 swings back and forth to use a brush to crush the blockages in the mesh of the rotor. Then, the absorption component 44 absorbs the blockages, thereby achieving the function of cleaning the zeolite rotor. On the one hand, this solves the problem that blockages appear in the mesh of the existing rotor, thus affecting the normal use of the zeolite rotor. On the other hand, dividing a whole zeolite adsorption disk into multiple independent adsorption disks can ensure the cleaning effect of the zeolite rotor, avoid the situation where the zeolite rotor cannot be completely cleaned due to excessive thickness, and effectively improve the cleaning efficiency of the zeolite rotor.

[0056] Furthermore, such as Figures 3-6 As shown, the adsorption disk assembly 22 includes a first adsorption disk 221 and a second adsorption disk 222 molded from powdered zeolite molecular sieves and arranged in an alternating manner, and a protective plate 223 disposed on the outside of the first adsorption disk 221 and the second adsorption disk 222.

[0057] The separating component 23 includes a separating ring 231 disposed on the central rotating shaft 11 and attached to the outside of the first adsorption disk 221 or the second adsorption disk 222, a plurality of separating rods 232 connected to the separating ring 231, and a separating strip 233 disposed between two adjacent adsorption disks and respectively connected to the separating rods 232.

[0058] In this embodiment, by setting up an adsorption disk assembly 22 and a separating assembly 23, the separating assembly 23 divides the adsorption disk assembly 22 into an adsorption zone, a desorption zone, and a cooling zone. When using a zeolite rotor for adsorption, multiple first adsorption disks 221 and second adsorption disks 222 can be combined into a single unit for use, or multiple first adsorption disks 221 and second adsorption disks 222 can be used separately for adsorption. Using multiple first adsorption disks 221 and second adsorption disks 222 separately for adsorption can prolong the flow time of VOCs inside the zeolite rotor, thereby ensuring that VOCs are completely adsorbed. In actual use, this provides users with more options, making it easier for operators to select the appropriate zeolite rotor speed and the spacing between multiple adsorption disks according to different VOCs, so as to improve the adsorption effect and adsorption efficiency of VOCs.

[0059] It should be noted that the first adsorption disk 221 and the second adsorption disk 222 are made by mixing the binder, zeolite molecular sieve and additives in a certain proportion and then molding them. The zeolite adsorbent prepared in this way has stable adsorption performance and can be easily modified by adding components.

[0060] The separating ring 231 is rotatably mounted to the central rotating shaft 11. As the central rotating shaft 11 drives the adsorption disk assembly 22 to rotate, the separating ring 231 and the separating rod 232 will not rotate with the adsorption disk assembly 22 under the action of gravity, so as to ensure that the positions of the adsorption zone, desorption zone and cooling zone remain unchanged. In addition, a sealing strip 234 is provided between the first adsorption disk 221 and the second adsorption disk 222 at the positions corresponding to the adsorption zone, desorption zone and cooling zone. The sealing strip 234 and the separating strip 233 separate the adsorption zone, desorption zone and cooling zone into different sealed areas to ensure that VOCs do not overflow during the adsorption and desorption process.

[0061] Furthermore, such as Figures 7-8 As shown, the drive assembly 32 includes a first drive unit 321 disposed on the support frame 31, a cross link 322 connected to the first drive unit 321 and disposed on the support frame 31, a sliding shaft 323 disposed on the support frame 31, and a plurality of sliding blocks 324 disposed on the sliding shaft 323 and connected to the cross link 322.

[0062] The sliding block 324 is connected to the protective plate 223 via the connecting rod 33.

[0063] In this embodiment, by setting the driving component 32 in conjunction with the adsorption disk component 22, the distance between multiple first adsorption disks 221 and second adsorption disks 222 can be moved away from or closer together, thereby facilitating the change of the spacing between two adjacent adsorption disks.

[0064] In detail, during use, the first drive unit 321 is controlled to work and drive the connecting rod at one end of the cross link 322 to move, causing multiple connecting rods in the cross link 322 to rotate simultaneously. At the same time, multiple sliding blocks 324 connected to the cross link 322 slide on the sliding shaft 323, and the distance between two adjacent adsorption disks always remains the same. When the distance between the first adsorption disk 221 and the second adsorption disk 222 increases, on the one hand, it is convenient for the impurity removal mechanism 4 to extend into the gap between the first adsorption disk 221 and the second adsorption disk 222 and clean the first adsorption disk 221 and the second adsorption disk 222. On the other hand, by increasing the overall length of the adsorption disk assembly 22, the residence time of the exhaust gas inside the adsorption disk assembly 22 is extended, thereby improving the purification effect of the exhaust gas.

[0065] It should be noted that in order to ensure that the connecting rod 33 can slide on the cylindrical part 21, a through groove adapted to the connecting rod 33 needs to be opened at the upper end of the cylindrical part 21.

[0066] Furthermore, such as Figures 9-13 As shown, the intermittent control component 41 includes:

[0067] The driving component 411 includes a control housing 4111, a second driving unit 4112 disposed inside the control housing 4111, a worm gear 4113 connected to the second driving unit 4112, and a worm wheel 4114 that cooperates with the worm gear 4113 and is rotatably disposed inside the control housing 4111.

[0068] Rotating component 412, the rotating component 412 includes a reduction unit 4121 connected to the worm gear 4113, a rotating shaft 4122 connected to the reduction unit 4121, and two limiting plates 4123 disposed on the rotating shaft 4122;

[0069] The swinging component 413 includes a cam 4131 coaxially arranged with the worm gear 4114, a drive rod 4133 arranged outside the cam 4131 and connected at the other end to the swing rod 4132, and a limiting block 4134 hinged to one end of the swing rod 4132.

[0070] The deceleration unit 4121 and the rotating shaft 4122 can slide relative to each other, and the limiting block 4134 is engaged between the two limiting plates 4123.

[0071] In this embodiment, by setting the driving component 411 in conjunction with the rotating component 412 and the swinging component 413, the back-and-forth swinging and rotating functions of the crushing component 43 can be realized, which facilitates the movement of the crushing component 43 and the crushing operation.

[0072] In detail, during operation, the intermittent control component 41 needs to drive the crushing component 43 to rotate to the position of the adsorption disk component 22. First, the second drive unit 4112 works and drives the worm gear 4113 to rotate. After the worm gear 4113 rotates, it drives the rotating shaft 4122 to rotate through the reduction unit 4121. The rotating shaft 4122 will drive the crushing component 43 to rotate to the position of the adsorption disk component 22. At the same time that the worm gear 4113 drives the reduction unit 4121, the worm gear 4113 will also drive the worm wheel 4114 to rotate and drive the cam 4131 to rotate. After the cam 4131 rotates, it will drive the swing rod 4132 to swing back and forth and drive the drive rod 4133 to swing. Finally, the drive rod 4133 will drive the rotating shaft 4122 to reciprocate through the limit block 4134. Therefore, the crushing component 43 will also reciprocate while rotating.

[0073] After the crushing component 43 enters the interior of the adsorption disk assembly 22, the crushing component 43 no longer needs to rotate. It only needs to move back and forth and cooperate with the rotation of the adsorption disk assembly 22 to complete the crushing and cleaning work of the first adsorption disk 221 and the second adsorption disk 222 inside the adsorption disk assembly 22. For this purpose, the second drive unit 4112 needs to alternately rotate forward and reverse to control the crushing component 43 to stay in the same position as much as possible.

[0074] It should be noted that since the crushing component 43 is also reciprocating during rotation, in order to ensure that the crushing component 43 can smoothly enter the interior of the adsorption disk assembly 22, before the intermittent control component 41 drives the crushing component 43 into the interior of the adsorption disk assembly 22, it is necessary to control the distance between the first adsorption disk 221 and the second adsorption disk 222 to be greater than the displacement length of the reciprocating movement of the crushing component 43, so as to ensure that the crushing component 43 will not interfere with the first adsorption disk 221 and the second adsorption disk 222. After the crushing component 43 enters the interior of the adsorption disk assembly 22, the first drive unit 321 can be controlled to work and the distance between the first adsorption disk 221 and the second adsorption disk 222 can be appropriately reduced, so that the crushing component 43 can extend into the inside of the rotating mesh of the first adsorption disk 221 and the second adsorption disk 222, so as to crush and clean the first adsorption disk 221 and the second adsorption disk 222.

[0075] The reduction unit 4121 consists of multiple large and small gears that cooperate with each other, which is existing technology and will not be described in detail here.

[0076] Furthermore, such as Figure 16 As shown, the moving component 42 includes a first telescopic unit 421 for driving the intermittent control component 41 to move and connected to the control box 4111, a second telescopic unit 422 for driving the first telescopic unit 421 to move, and a slide rail 423 adapted to the first telescopic unit 421.

[0077] The purification chamber mechanism 1 has a partition 12 that cooperates with the cylindrical component 21 on the side near the intermittent control component 41. The partition 12 includes a first fixed plate 121, a second fixed plate 122, and a movable plate 123 that is disposed between the first fixed plate 121 and the second fixed plate 122 and is detachably disposed therebetween.

[0078] In this embodiment, by setting the moving component 42 in conjunction with the intermittent control component 41, the intermittent control component 41 can be controlled to smoothly enter the interior of the cylindrical component 21.

[0079] In detail, during use, the movable plate 123 is first removed from the first fixed plate 121 and the second fixed plate 122 (at this time, the connection between the first fixed plate 121 and the movable plate 123 is located at the position of the rotating shaft 4122 and the main suction pipe 443. Pull the movable plate 123 outward and then take it out along the side). Then the first telescopic unit 421 and the second telescopic unit 422 work simultaneously and drive the intermittent control component 41 and the crushing component 43 into the interior of the cylindrical part 21.

[0080] It should be noted that the movable plate 123 is set at the position of the opening 2111 in the corresponding cylindrical body 211. After the crushing component 43 and the absorption component 44 enter the interior of the cylindrical part 21, the rotating shaft 4122 and the main suction pipe 443 will be set in the gap between the cylindrical part 21 and the adsorption plate assembly 22. When the adsorption plate assembly 22 rotates, causing the connecting rod 33 to interfere with the rotating shaft 4122 or the main suction pipe, the adsorption plate assembly 22 will rotate in the opposite direction to complete the cleaning work. Therefore, the operator only needs to clean the adsorption plate assembly 22 near the connecting rod 33.

[0081] Furthermore, such as Figures 10-15 As shown, the crushing assembly 43 includes a plurality of crushing plates 431 fixedly mounted on the rotating shaft 4122 and a brush 432 mounted on one side of the crushing plates 431.

[0082] The purification chamber mechanism 1 is also provided with a cleaning tank 13 for placing the crushing component 43. The cleaning tank 13 is provided with an inlet 131 for controlling the entry of cleaning liquid and an outlet 132 for discharging waste liquid.

[0083] In this embodiment, after the crushing component 43 enters the interior of the adsorption plate assembly 22, when the second drive unit 4112 drives the rotating shaft 4122 to reciprocate, the rotating shaft 4122 will also drive the crushing plate 431 to reciprocate, and the brush 432 will clean the inside of the rotating wheel mesh until the sticky state between the blockage and the rotating wheel is broken. Then the second drive unit 4112 works and drives the crushing component 43 to rotate into the interior of the cleaning bucket 13. The second drive unit 4112 can work again and drive the crushing component 43 to reciprocate to clean the blockage attached to the brush 432. It is necessary to ensure that when the crushing component 43 enters the interior of the cleaning bucket 13, the impurity removal mechanism 4 will not interfere with the translation mechanism 3.

[0084] Furthermore, such as Figures 10-14 As shown, the absorption assembly 44 includes a negative pressure unit 441 disposed on the purification chamber, a negative pressure suction pipe 442 connected to the negative pressure unit 441, a main suction pipe 443 connected to the negative pressure suction pipe 442 and disposed on the control chamber 4111, a plurality of branch suction pipes 444 connected to the main suction pipe 443 and disposed on the upper end of the crushing plate 431, and a plurality of suction nozzles 445 disposed on the branch suction pipes 444;

[0085] The main suction pipe 443 is internally equipped with a filter screen 446 for filtering and collecting impurities.

[0086] In this embodiment, by setting up an absorption component 44 in conjunction with a crushing component 43, after the absorption component 44 completes the crushing work of the crushing component 43, the absorption component 44 can absorb the crushed blockage to achieve the cleaning of the rotor.

[0087] In detail, when the negative pressure machine 441 is working, it sucks the blockage inside the rotor mesh through the suction nozzle 445 and into the branch suction pipe 444 and the main suction pipe 443. Inside the main suction pipe 443, the blockage is intercepted on the filter screen 446 and collected. The operator needs to clean the blockage on the filter screen 446 inside the main suction pipe 443 regularly.

[0088] Example 2

[0089] like Figures 17-18 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0090] Furthermore, the cylindrical component 21 includes a cylindrical body 211 with an opening 2111 and a sliding cover plate 212 that cooperates with the cylindrical body 211 and is used to seal the opening 2111. A sealing strip 213 is provided on the sliding cover plate 212.

[0091] The end of the sliding cover 212 is also provided with a pull handle 214, and the cylindrical part 21 is provided with a magnet 215 at the position corresponding to the pull handle 214. The pull handle 214 is made of metal.

[0092] It is worth mentioning that a sliding cover plate 212 is provided on the cylindrical part 21 to facilitate the opening and closing of the opening 2111 in the cylindrical body 211, thereby facilitating the entry of the crushing component 43. At the same time, a sealing strip 213 is provided on the sliding cover plate 212 to ensure the sealing of the cylindrical part 21. When the crushing component 43 needs to enter the interior of the cylindrical part 21, the pull handle 214 is turned so that the pull handle 214 is attracted to the magnet block 215, so that the crushing component 43 can smoothly enter the interior of the cylindrical part 21.

[0093] Work process:

[0094] When the adsorption disk is unfolded and the adsorption disk assembly 22 needs to be cleaned, the translation mechanism 3 is first used to move multiple first adsorption disks 221 and second adsorption disks 222 away from each other, thereby increasing the distance between two adjacent adsorption disks.

[0095] When the impurity removal mechanism 4 enters, the movable plate 123 on the purification box mechanism 1 is opened first, and the moving component 42 drives the intermittent control component 41, as well as the crushing component 43 and the absorption component 44, into the interior of the cylindrical component 21.

[0096] In the impurity removal process, the drive component 411, together with the rotating component 412 and the swing component 413, drives the crushing component 43 to move back and forth inside the cylindrical component 21, and the brush 432 cleans the inside of the rotating wheel mesh, and the absorption component 44 can absorb the blockage after crushing.

[0097] After the cleaning work is completed, the moving component 42 drives the intermittent control component 41, the crushing component 43, and the absorption component 44 to reset. At the same time, the crushing component 43 enters the cleaning bucket 13 to complete the cleaning work.
