Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment devices, and in particular to a waste gas treatment device for a coating production line. Background Art

[0002] Paint shop exhaust primarily consists of organic solvents contained in paint and decomposition products of the coating during spraying and drying, collectively known as volatile organic compounds (VOCs). These compounds, primarily benzene, toluene, and xylene, are harmful to human health and the living environment, and also have a foul odor. In recent years, with growing environmental awareness, the continuous improvement of national environmental regulations, and the strengthening of law enforcement, paint manufacturers are requiring new paint lines to be equipped with exhaust gas treatment equipment. Existing lines are also being gradually upgraded and upgraded. Exhaust gases must be treated to meet standards before they can be discharged.

[0003] Referring to the Chinese patent application document with publication number CN115318035B, the subject name is "An exhaust gas treatment device for coating machinery and equipment". The device uses two relatively rotating movable filter plates and a fixed filter plate to drive the fan blades after the filtered exhaust gas to cause relative rotation between the movable filter plate and the fixed filter plate, thereby accelerating the exhaust gas flow and achieving self-cleaning.

[0004] The above-mentioned technical solution requires intermittent operation of the activated carbon processor, which requires frequent movement from the adsorption chamber to the desorption chamber to remove impurities adsorbed on the activated carbon processor. After removal, the activated carbon processor must be replaced and reused in the adsorption chamber, resulting in low treatment efficiency. Furthermore, after a certain period of use, the activated carbon processor needs to be shut down for replacement, which reduces work efficiency. Summary of the Invention

[0005] In view of this, the present invention provides an exhaust gas treatment device for a coating production line, which can not only keep the machine running when replacing the adsorption barrel, but also reduce the probability of exhaust gas leakage when replacing the adsorption barrel.

[0006] The present application provides an exhaust gas treatment device for a coating production line, which adopts the following technical solution, including: a mounting frame and an adsorption mechanism arranged in the mounting frame; the adsorption mechanism is provided with a plurality of adsorption barrels that have not been adsorbed, and the adsorption barrels are used to adsorb exhaust gas; a desorption mechanism is provided in the mounting frame, and the desorption mechanism is arranged at one end away from the adsorption mechanism, and the desorption mechanism is used to desorb the adsorption barrels after adsorption; a replacement chamber is provided at a middle position between the adsorption mechanism and the desorption mechanism, a material replacement port is provided at a middle position of the connection between the replacement chamber and the mounting frame, a material replacement pull rod is slidably connected to the bottom of the replacement chamber, and the material replacement pull rod is used to move the adsorption barrels located at both ends of the replacement chamber to the material replacement port.

[0007] By adopting the above technical solution, the mounting frame is placed on a horizontal surface, multiple adsorption barrels are placed in the adsorption mechanism, and adsorption barrels that have not been adsorbed are placed in the replacement chamber. Exhaust gas is introduced into the adsorption mechanism so that the adsorption barrel adsorbs the exhaust gas. After the adsorption of the adsorption barrel reaches saturation, the refueling rod located at the refueling port is pulled, so that the refueling rod drives the adsorption barrel located at the refueling port to move to the side of the replacement chamber, and continues to place adsorption barrels that have not been adsorbed at the refueling port, opens the sealing mechanism on one side of the adsorption mechanism, and opens the rotating mechanism at the same time, so that the rotating mechanism moves an adsorption barrel located in the adsorption chamber to the replacement chamber, and the rotating mechanism drives the adsorption barrel located on the side of the replacement chamber to move to the adsorption mechanism, and then again Pull the material changing rod so that it drives the adsorption barrel at the material changing port to move to the side of the replacement chamber, start the rotating mechanism again, and open the sealing mechanism at the desorption mechanism at the same time, so that the rotating mechanism drives the adsorption barrel in the replacement chamber after adsorption to move to the desorption mechanism, repeat this process, so that all the adsorption barrels after adsorption are moved to the desorption mechanism, and the adsorption barrels that have not been adsorbed are moved to the adsorption mechanism. When it is necessary to replace the adsorption barrel that has reached the number of uses, the adsorption barrel that has reached the number of uses is moved from the desorption mechanism to the replacement chamber, and slide the material changing rod so that the material changing rod drives the adsorption barrel that has reached the number of uses to move from the side wall of the replacement chamber to the material changing port, and the adsorption barrel is taken out and replaced.

[0008] The sealing and rotating mechanisms ensure continuous production by allowing the adsorption barrel to be replaced without stopping the production line, ensuring continuous operation of the exhaust gas treatment device. This reduces the probability of production line shutdowns due to adsorption barrel replacements and minimizes losses caused by production interruptions. Furthermore, the sealing mechanism allows the adsorption barrel to be replaced without stopping the production line, enhancing the ability of the adsorption barrel to continue treating exhaust gas during the replacement process, reducing direct emissions of harmful substances. Furthermore, the continued treatment of exhaust gas during the replacement process enhances the stability of exhaust gas treatment efficiency.

[0009] Optionally, the adsorption mechanism includes: an adsorption chamber opened on the mounting frame, the adsorption chamber is used to adsorb waste gas, a waste gas inlet opened on the mounting frame, the waste gas inlet is used to pass waste gas that has not been adsorbed by the adsorption barrel, and a waste gas outlet opened on the mounting frame, the waste gas outlet is used to pass out waste gas that has been adsorbed by the adsorption barrel.

[0010] By adopting the above technical solution, waste gas is introduced into the waste gas inlet, so that the waste gas enters the adsorption chamber through the waste gas inlet, the adsorption barrel in the adsorption chamber treats the waste gas, and the treated waste gas is introduced into the waste gas outlet through the adsorption chamber, and then moved to the next waste gas treatment device, and this process is repeated.

[0011] Optionally, the desorption mechanism includes: a desorption chamber opened on the mounting frame, and the desorption chamber is arranged at one end away from the adsorption chamber, the adsorption chamber is used to desorb the adsorption barrel after adsorption, a hot air inlet opened on the mounting frame, the hot air inlet is connected to the hot air and the desorption chamber, the hot air inlet is used to introduce high-temperature gas into the desorption chamber, a hot air outlet opened on the mounting frame, and arranged at one end away from the hot air inlet, the hot air outlet is used to pass the high-temperature gas that has undergone desorption.

[0012] By adopting the above technical solution, when it is necessary to desorb the saturated adsorption barrel, high-temperature gas is introduced into the hot air inlet to desorb the gas in the adsorption barrel. After desorption, the gas moves from the desorption chamber to the hot air outlet to discharge the high-temperature gas, and at the same time, the substances accompanying the high-temperature gas are further processed.

[0013] Optionally, a sealing mechanism is provided on a side of the adsorption mechanism and the desorption mechanism close to the replacement chamber, and the sealing mechanism is used to maintain the sealing of the adsorption mechanism and the desorption mechanism.

[0014] Optionally, the sealing mechanism includes: sealing plates fixedly connected to both sides of the replacement chamber, a movable opening being opened at the connection between the sealing plate and the mounting frame, the movable opening being used to pass the adsorption barrel, a sliding baffle being slidably connected to the sealing plate, the sliding baffle being used to maintain the sealing state of the movable opening, a recovery rope being fixedly connected to the sliding baffle, the recovery rope being used to drive the sliding baffle to move away from the movable opening.

[0015] Optionally, a return spring is fixedly connected to the sliding baffle, and the return spring is fixedly connected to the sealing plate at a side away from the sliding baffle. The return spring is used to push the sliding baffle to move closer to the moving opening.

[0016] By adopting the above technical solution, when the sealing mechanism needs to be opened, the recovery rope is pulled, so that the recovery rope pulls the sliding baffle to open, and the sliding baffle moves out from the moving port. At this time, the adsorption barrel is driven to move and the position of the adsorption barrel is replaced. When the sealing mechanism needs to be closed, the recovery rope is released, and the reset spring pushes the sliding baffle to move close to the moving port, so that the sliding baffle seals the moving port.

[0017] The setting of the sealing mechanism, on the one hand, can ensure the continuous operation of the device when the adsorption barrel is replaced. By different sealing of the adsorption mechanism and the desorption mechanism, the probability of exhaust gas moving directly from the adsorption mechanism to the desorption mechanism during the replacement process is reduced. On the other hand, the sealing mechanism seals the adsorption mechanism during replacement, reducing the probability of exhaust gas being directly discharged from the material replacement port when the adsorption barrel is replaced, ensuring the sealing of the exhaust gas treatment process and enhancing the operating efficiency of the exhaust gas treatment device.

[0018] Optionally, a rotating mechanism is provided at the bottom end of the mounting frame, and the rotating mechanism is used to drive the adsorption barrel to move.

[0019] Optionally, the rotating mechanism includes a first driven groove at the bottom of the adsorption barrel, a rotating disk hinged at the bottom of the mounting frame, and a first rotating tooth on the upper surface of the rotating disk, the first rotating tooth is used to engage with the first driven groove and drive the adsorption barrel to move.

[0021] By adopting the above technical solution, the linear mover is started, so that the second rotating tooth on the linear mover engages with the second driven groove, driving the rotating disk to rotate. The rotation of the rotating disk drives the first driven tooth to engage with the first driven groove located below the adsorption bucket. The rotation of the rotating disk drives the adsorption bucket to move. A one-way bearing is provided at the connection between the second rotating tooth and the rotating disk. The one-way bearing is responsible for driving the second driven groove to rotate by the second driven tooth when the linear mover moves forward, and drives the rotating disk to rotate. When the linear mover is retracted, the rotating disk cannot rotate. The linear mover is retracted, so that the recovery block on the linear mover pushes the recovery rope to move, and the recovery rope is pulled to open the sliding baffle and move the adsorption bucket.

[0022] The setting of the rotating mechanism can, on the one hand, drive the adsorption barrel to move, so that the adsorption barrel moves from the adsorption chamber to the replacement chamber, or from the desorption chamber to the replacement chamber, and can release the organic matter and other pollutants on the adsorption barrel, realize the reuse of the adsorption barrel, and reduce the cost of waste gas treatment. On the other hand, the desorbed adsorption barrel is moved back to the adsorption chamber, and the regeneration performance of the activated carbon in the adsorption barrel is utilized to re-adsorb harmful substances, thereby improving the waste gas treatment efficiency. By regularly desorbing the activated carbon in the adsorption barrel, the adsorption performance of the activated carbon can be maintained, thereby enhancing the stability of the waste gas treatment process.

[0023] Optionally, a plurality of adsorption ports are provided on the side wall of the adsorption barrel, and the adsorption ports are used to adsorb impurities in the exhaust gas.

[0024] By adopting the above technical solution, multiple adsorption ports can increase the contact area between the activated carbon and the exhaust gas in the adsorption barrel, improve the adsorption efficiency, and at the same time reduce the resistance of the exhaust gas to move through the adsorption chamber.

[0025] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects: 1. The configuration of the sealing mechanism and the rotating mechanism ensures production continuity. By replacing the adsorption barrel without stopping the machine, the exhaust gas treatment device can continue to operate, reducing the probability of production line shutdowns due to the replacement of the adsorption barrel and minimizing losses caused by production interruptions. Furthermore, the configuration of the sealing mechanism allows the adsorption barrel to be replaced without stopping the machine, enhancing the ability of the adsorption barrel to continue to treat exhaust gas during the replacement process, reducing the direct emission of harmful substances. At the same time, the exhaust gas can be continuously treated during the replacement process, enhancing the stability of the exhaust gas treatment efficiency.

[0026] 2. The setting of the sealing mechanism, on the one hand, can ensure the continuous operation of the device when the adsorption barrel is replaced. By sealing the adsorption mechanism and the desorption mechanism differently, the probability of the exhaust gas moving directly from the adsorption mechanism to the desorption mechanism during the replacement process is reduced. On the other hand, the sealing mechanism seals the adsorption mechanism during replacement, reducing the probability of the exhaust gas being directly discharged from the material replacement port when the adsorption barrel is replaced, ensuring the sealing of the exhaust gas treatment process and enhancing the operating efficiency of the exhaust gas treatment device.

[0027] 3.

On the other hand, the desorbed adsorption barrel is moved back to the adsorption chamber, and the regeneration performance of the activated carbon in the adsorption barrel is utilized to re-adsorb harmful substances, thereby improving the waste gas treatment efficiency. By regularly desorbing the activated carbon in the adsorption barrel, the adsorption performance of the activated carbon can be maintained, thereby enhancing the stability of the waste gas treatment process.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figures 1-9 , the technical solutions of the embodiments of the present invention are clearly and completely described. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5This embodiment provides an exhaust gas treatment device for a coating production line, comprising a mounting frame 1 placed on a horizontal surface, wherein the mounting frame 1 is provided with an adsorption mechanism 2, wherein the adsorption mechanism 2 is provided with a plurality of adsorption barrels 3 that have not been adsorbed, and the adsorption mechanism 2 is used to adsorb exhaust gas. A desorption mechanism 4 is provided in the mounting frame 1, and the desorption mechanism 4 is provided at an end of the mounting frame 1 away from the adsorption mechanism 2. The desorption mechanism 4 is used to introduce hot air and desorb the adsorption barrels 3. A replacement chamber 5 is provided between the adsorption mechanism 2 and the desorption mechanism 4, and a material replacement port 51 is provided between the connection between the replacement chamber 5 and the mounting frame 1. A material replacement pull rod 52 is slidably connected below the replacement chamber 5, and the material replacement pull rod 52 is used to move the adsorption barrels 3 located at both ends of the replacement chamber 5 to the material replacement port 51. A sealing mechanism 6 is provided on the side of the adsorption mechanism 2 and the desorption mechanism 4 close to the replacement chamber 5, and the sealing mechanism 6 is used to maintain the sealing of the adsorption mechanism 2 and the desorption mechanism 4; a rotating mechanism 7 is provided at the bottom end of the mounting frame 1, and the rotating mechanism 7 is used to drive the adsorption barrels 3 to move.

[0032] Place the mounting frame 1 on a horizontal surface, place multiple adsorption barrels 3 in the adsorption mechanism 2, place an adsorption barrel 3 that has not been adsorbed in the replacement chamber 5, introduce exhaust gas into the adsorption mechanism 2, and allow the adsorption barrel 3 to adsorb the exhaust gas. After the adsorption of the adsorption barrel 3 reaches saturation, pull the refueling rod 52 at the refueling port 51, so that the refueling rod 52 drives the adsorption barrel 3 at the refueling port 51 to move to the side of the replacement chamber 5, and continue to place an adsorption barrel 3 that has not been adsorbed at the refueling port 51, open the sealing mechanism 6 on one side of the adsorption mechanism 2, and open the rotating mechanism 7 at the same time, so that the rotating mechanism 7 moves one adsorption barrel 3 at the adsorption chamber 21 to the side of the replacement chamber 5. The adsorption barrel 3 in the replacement chamber is moved to the replacement chamber 5, and the rotating mechanism 7 drives the adsorption barrel 3 located on the side of the replacement chamber 5 to move to the adsorption mechanism 2. At this time, the material replacement rod 52 is pulled again, so that the material replacement rod 52 drives the adsorption barrel 3 located at the material replacement port 51 to move to the side of the replacement chamber 5, and the rotating mechanism 7 is started again. At the same time, the sealing mechanism 6 located at the desorption mechanism 4 is opened, so that the rotating mechanism 7 drives the adsorption barrel 3 located in the replacement chamber 5 after adsorption to move to the desorption mechanism 4. Repeat this process, so that all the adsorption barrels 3 after adsorption are moved to the desorption mechanism 4, and the adsorption barrels 3 that have not been adsorbed are moved to the adsorption mechanism 2.

[0033] When it is necessary to replace the adsorption barrel 3 that has reached the end of its use times, the adsorption barrel 3 that has reached the end of its use times is moved from the desorption mechanism 4 to the replacement chamber 5, and the material replacement rod 52 is slid so that the material replacement rod 52 drives the adsorption barrel 3 that has reached the end of its use times to move from the side wall of the replacement chamber 5 to the material replacement port 51, and the adsorption barrel 3 is taken out and replaced.

[0034] The provision of the sealing mechanism 6 and the rotating mechanism 7 ensures, on the one hand, the continuity of production. By replacing the adsorption barrel 3 without stopping the production line, the continuous operation of the exhaust gas treatment device is ensured, thereby reducing the probability of production line shutdowns due to the replacement of the adsorption barrel 3 and minimizing losses caused by production interruptions. On the other hand, the provision of the sealing mechanism 6 allows the adsorption barrel 3 to be replaced without stopping the production line, thereby enhancing the ability of the adsorption barrel 3 to continue to treat exhaust gas during the replacement process, reducing the direct emission of harmful substances, and simultaneously ensuring that exhaust gas treatment can continue during the replacement process of the adsorption barrel 3, thereby enhancing the stability of exhaust gas treatment efficiency.

[0035] Reference Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The sealing mechanism 6 includes a sealing plate 61 fixedly connected to both sides of the replacement chamber 5. A movable opening 62 is formed at the connection between the sealing plate 61 and the mounting frame 1. The movable opening 62 is used to pass the adsorption barrel 3. A sliding baffle 63 is slidably connected to the sealing plate 61. The sliding baffle 63 is used to maintain the sealing state of the movable opening 62. A return spring 64 is fixedly connected to the sliding baffle 63. The return spring 64 is fixedly connected to the sealing plate 61 on the side away from the sliding baffle 63. The return spring 64 is used to push the sliding baffle 63 to move closer to the movable opening 62. A recovery rope 65 is fixedly connected to the sliding baffle 63. The recovery rope 65 is used to drive the sliding baffle 63 to move away from the movable opening 62.

[0036] When the sealing mechanism 6 needs to be opened, the recovery rope 65 is pulled, so that the recovery rope 65 pulls the sliding baffle 63 to open, and the sliding baffle 63 moves out from the moving port 62. At this time, the adsorption barrel 3 is driven to move and the position of the adsorption barrel 3 is changed. When the sealing mechanism 6 needs to be closed, the recovery rope 65 is loosened, and the return spring 64 pushes the sliding baffle 63 to move close to the moving port 62, so that the sliding baffle 63 seals the moving port 62.

[0037] The setting of the sealing mechanism 6, on the one hand, can ensure the continuous operation of the device when the adsorption barrel 3 is replaced. By sealing the adsorption mechanism 2 and the desorption mechanism 4 differently, the probability of the exhaust gas moving directly from the adsorption mechanism 2 to the desorption mechanism 4 during the replacement process is reduced. On the other hand, the sealing mechanism 6 seals the adsorption mechanism 2 during replacement, reducing the probability of the exhaust gas being directly discharged from the material replacement port 51 when the adsorption barrel 3 is replaced, thereby ensuring the sealing of the exhaust gas treatment process and enhancing the operating efficiency of the exhaust gas treatment device.

[0038] Reference Figure 4The adsorption mechanism 2 includes an adsorption chamber 21 provided on the mounting frame 1 for adsorbing the exhaust gas. The mounting frame 1 is provided with an exhaust gas inlet 22 for admitting exhaust gas that has not been adsorbed by the adsorption barrel 3. The mounting frame 1 is provided with an exhaust gas outlet 23 at one end away from the exhaust gas inlet 22 for discharging exhaust gas that has been adsorbed by the adsorption barrel 3.

[0039] The waste gas is introduced into the waste gas inlet 22, so that the waste gas enters the adsorption chamber 21 through the waste gas inlet 22, and the adsorption barrel 3 in the adsorption chamber 21 treats the waste gas. The treated waste gas is introduced into the waste gas outlet 23 through the adsorption chamber 21, and then moves to the next waste gas treatment device, and this process is repeated.

[0040] Reference Figure 4 The desorption mechanism 4 includes a desorption chamber 41 provided on the mounting frame 1 and at one end away from the adsorption chamber 21. The desorption chamber 41 is used to desorb the adsorption barrel 3 after adsorption. A hot air inlet 42 is provided on the mounting frame 1. The hot air inlet 42 communicates with the hot gas and the desorption chamber 41. The hot air inlet 42 is used to introduce high-temperature gas into the desorption chamber 41. A hot air outlet 43 is provided on the mounting frame 1 at one end away from the hot air inlet 42 and is located at the end away from the hot air inlet 42. The hot air outlet 43 is used to discharge the desorbed high-temperature gas.

[0041] When it is necessary to desorb the saturated adsorption barrel 3, high-temperature gas is introduced into the hot air inlet 42 to desorb the gas in the adsorption barrel 3. After desorption, the gas moves from the desorption chamber 41 to the hot air outlet 43 to discharge the high-temperature gas, and at the same time, the substances accompanying the high-temperature gas are further processed.

[0042] Reference Figure 5 、 Figure 8 and Figure 9 The rotating mechanism 7 includes a first driven groove 71 provided at the bottom of the adsorption barrel 3. A rotating disk 72 is hinged at the bottom of the mounting frame 1, and a first rotating tooth 73 is provided on the upper surface of the rotating disk 72. The first rotating tooth 73 is used to engage with the first driven groove 71 and drive the adsorption barrel 3 to move. A linear mover 74 is fixedly connected to the bottom position of the mounting frame 1, and a second rotating tooth 75 is fixedly connected to the output shaft of the linear mover 74. A second driven groove 76 is fixedly connected to the middle position of the rotating disk 72, and the second driven groove 76 can engage with the second rotating tooth 75. A recovery block 77 is fixedly connected to the output shaft of the linear mover 74. The recovery block 77 is used to pull the recovery rope 65 to move when the linear mover 74 is recovered.

[0043] Start the linear mover 74, so that the second rotating tooth 75 on the linear mover 74 engages with the second driven groove 76, driving the rotating disk 72 to rotate. The rotation of the rotating disk 72 drives the first driven tooth to engage with the first driven groove 71 located below the adsorption bucket 3. The rotation of the rotating disk 72 drives the adsorption bucket 3 to move. A one-way bearing is provided at the connection between the second rotating tooth 75 and the rotating disk 72. The one-way bearing is responsible for driving the second driven groove 76 to rotate by the second driven tooth when the linear mover 74 moves forward, and drives the rotating disk 72 to rotate. When the linear mover 74 is retracted, the rotating disk 72 cannot rotate. The linear mover 74 is retracted, so that the recovery block 77 on the linear mover 74 pushes the recovery rope 65 to move, and pulls the recovery rope 65 to open the sliding baffle 63 and move the adsorption bucket 3.

[0044] The setting of the rotating mechanism 7, on the one hand, can drive the adsorption barrel 3 to move, so that the adsorption barrel 3 moves from the adsorption chamber 21 to the replacement chamber 5, or moves from the desorption chamber 41 to the replacement chamber 5, and can release the organic matter and other pollutants on the adsorption barrel 3, thereby realizing the reuse of the adsorption barrel 3 and reducing the cost of waste gas treatment. On the other hand, the desorbed adsorption barrel 3 is moved back to the adsorption chamber 21, and by utilizing the regeneration performance of the activated carbon in the adsorption barrel 3, harmful substances are re-adsorbed, thereby improving the waste gas treatment efficiency. By regularly desorbing the activated carbon in the adsorption barrel 3, the adsorption performance of the activated carbon can be maintained, thereby enhancing the stability of the waste gas treatment process.

[0045] Reference Figure 8 The sidewall of the adsorption barrel 3 is provided with a plurality of adsorption ports 31 for adsorbing impurities in the exhaust gas. The plurality of adsorption ports 31 increases the contact area between the activated carbon in the adsorption barrel 3 and the exhaust gas, improving adsorption efficiency while reducing the resistance to the exhaust gas moving through the adsorption chamber 21.

[0046] The implementation principle of an exhaust gas treatment device for a coating production line in an embodiment of the present application is as follows: placing a mounting frame 1 on a horizontal plane, placing a plurality of adsorption barrels 3 in the adsorption mechanism 2, placing an adsorption barrel 3 that has not been adsorbed in the replacement chamber 5, introducing exhaust gas into the exhaust gas inlet 22, allowing the exhaust gas to enter the adsorption chamber 21 through the exhaust gas inlet 22, the adsorption barrel 3 in the adsorption chamber 21 treats the exhaust gas, the treated exhaust gas is introduced into the exhaust gas outlet 23 through the adsorption chamber 21, and then moved to the next exhaust gas treatment device, and this process is repeated.

[0047] When the adsorption barrel 3 is in a saturated state, the refueling rod 52 located at the refueling port 51 is pulled, so that the refueling rod 52 drives the adsorption barrel 3 located at the refueling port 51 to move to the side of the replacement chamber 5, and continues to place the adsorption barrel 3 that has not been adsorbed at the refueling port 51, and the linear mover 74 is recovered, so that the recovery block 77 on the linear mover 74 pushes the recovery rope 65 to move, and the recovery rope 65 is pulled to open the sliding baffle 63 near the adsorption chamber 21. At this time, the adsorption chamber 21 and the replacement chamber 5 are connected, and the linear mover 74 is started to make the linear The second rotating tooth 75 on the mover 74 engages with the second driven groove 76, driving the rotating disk 72 to rotate. The rotation of the rotating disk 72 drives the first driven tooth to engage with the first driven groove 71 located below the adsorption barrel 3. The rotation of the rotating disk 72 drives the adsorption barrel 3 to move, so that an adsorption barrel 3 located in the adsorption chamber 21 moves to the replacement chamber 5, and at the same time drives the adsorption barrel 3 located on the side of the replacement chamber 5 to move into the adsorption mechanism 2. At this time, the material change rod 52 is pulled again, so that the material change rod 52 drives the adsorption barrel 3 located at the material change port 51 to move to the side of the replacement chamber 5.

[0048] The linear mover 74 is retracted, so that the recovery block 77 on the linear mover 74 pushes the recovery rope 65 to move, and the recovery rope 65 is pulled to open the sliding baffle 63 near the desorption chamber 41 and close the sliding baffle 63 near the adsorption chamber 21. At this time, the desorption chamber 41 and the replacement chamber 5 are connected, and the linear mover 74 is started, so that the second rotating tooth 75 on the linear mover 74 engages with the second driven groove 76, driving the rotating disk 72 to rotate. The rotation of the rotating disk 72 drives the first driven tooth to engage with the first driven groove 71 located below the adsorption barrel 3. The rotation of the rotating disk 72 drives the adsorption barrel 3 to move, so that the adsorption barrel 3 moved from the adsorption chamber 21 to the replacement chamber 5 moves from the replacement chamber 5 to the desorption chamber 41, and this process is repeated so that all adsorption barrels 3 that need to be desorbed are moved to the desorption chamber 41.

[0049] When it is necessary to replace the adsorption barrel 3 that has reached the end of its use times, the adsorption barrel 3 that has reached the end of its use times is moved from the desorption chamber 41 to the replacement chamber 5, and the material replacement rod 52 is slid so that the material replacement rod 52 drives the adsorption barrel 3 that has reached the end of its use times to move from the side wall of the replacement chamber 5 to the material replacement port 51, and the adsorption barrel 3 is taken out and replaced.

[0050] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
