Description

Technical Field

[0001] This invention relates to the field of deodorization technology for pig farms, and more particularly to a deodorization device and method for pig farms. Background Technology

[0002] The odor in pig farms mainly comes from gases produced by pigs' breathing and defecation, as well as gases produced by the decomposition of feed. The main components of these odors include harmful gases such as carbon dioxide, ammonia, and hydrogen sulfide, which are detrimental to the growth of pigs and the health of the farm workers. Therefore, it is necessary to keep the pigsty dry and well-ventilated, and to use deodorizing devices to exchange air, remove odors, and disinfect the pig farm in order to reduce the incidence of disease in pigs.

[0003] While high-efficiency activated carbon ventilation and deodorization devices can effectively filter and remove odors from the air, achieving odor purification, their design has certain limitations. Specifically, the amount of activated carbon used in such devices is usually fixed, lacking flexibility and making it difficult to dynamically adjust the thickness of the deodorization layer according to the actual air quality. This design flaw not only limits deodorization efficiency when air quality is poor but also leads to resource waste when air quality is good.

[0004] Furthermore, prolonged continuous operation of the deodorizing device accelerates the wear and tear of deodorizing materials such as activated carbon, shortening their lifespan and increasing replacement costs. More problematic is that during extended contact with odorous gases, the surface of the device easily absorbs and deposits large amounts of pollutants, leading to channel blockage and consequently affecting the device's subsequent deodorization effect and airflow efficiency. Once blockage occurs, the device must be shut down for cleaning and maintenance, which not only impacts its continuous operation but also inconveniences users and incurs additional maintenance costs.

[0005] To address the aforementioned problems, this invention proposes a deodorization device and method for pig farms. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing high-efficiency activated carbon ventilation and deodorization devices, which, although capable of filtering and deodorizing odors, generally have a fixed amount of activated carbon, making it difficult to adjust the thickness of the activated carbon deodorization layer according to different air quality levels. Furthermore, prolonged operation of the deodorization device accelerates the wear and tear of the deodorizing material. Moreover, after extended use, the surfaces of the deodorization device that are in constant contact with odors are prone to clogging, affecting subsequent use and requiring cleaning only after the equipment is shut down, which is inconvenient. Therefore, this invention proposes a deodorization device and method for pig farms.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A deodorization device for pig farms includes a spray deodorization device, wherein an odor purification and regeneration mechanism is provided on one side of the spray deodorization device; The odor purification and regeneration mechanism includes a purification box, inside which are arranged multiple purification components. Two upper hooks are connected to the bottom of each purification component, and inclined rails are connected to both sides of each purification component. A regeneration component is provided below the purification box, and two side shells are provided between the purification box and the regeneration component. A transmission component is provided in the side shell, and a guide wheel is connected to the transmission component. The transmission component drives the guide wheel to move horizontally, so that the guide wheel passes through the inclined rail and presses the purification component smoothly into the regeneration component, so that the guide wheel enters the inclined rail and presses the purification component in sequence. The regeneration component is equipped with two sets of lower limit sleeves, two adjustable positioning components, two fixed release components, and multiple parallel dual-control limit components. The adjustable positioning components lock with the lower limit sleeves, so that the downward-pressed purification components lock with the dual-control limit components individually. After the adjustable positioning components lock with the dual-control limit components upward, the dual-control limit components are connected together. At this time, the downward-adjusting purification components switch up and down one by one.

[0008] Preferably, the regeneration assembly includes a regeneration box, which is fixedly connected to the side shell and the purification box. A conveying device is installed on one side of the regeneration box. The conveying device is connected to a conveying pipe and a three-way valve. The three-way valve is connected to the regeneration box. Both ends of the conveying pipe are connected to two nozzle groups, which are installed in the regeneration box.

[0009] Preferably, each group has multiple lower limit sleeves, and the lower limit sleeves are fixedly connected to the bottom wall of the regeneration box; The air inlet of the spray deodorization equipment is equipped with an odor sensor.

[0010] Preferably, the transmission assembly includes two drive shafts, which are rotatably mounted on the side housing via bearings. One of the drive shafts is fixedly connected to the output shaft of a motor, which is mounted on the purification chamber. A drive wheel is mounted on the drive shaft, and the two drive wheels are connected by a drive belt. The guide wheel is mounted on the drive belt.

[0011] Preferably, the fixing release assembly includes two first hydraulic devices, which are fixedly installed on the regeneration tank, and a push plate is fixedly connected to one end of each of the two first hydraulic devices.

[0012] Preferably, the dual-control limiting assembly includes a fixing plate, which is fixedly connected to the bottom wall of the recycling box. A first telescopic rod and a second spring are fixedly connected to both sides of the fixing plate. A connector is fixedly connected to one end of the first telescopic rod and the second spring. A second telescopic rod and a third spring are fixedly connected to one side of the connector. A lower grab hook is fixedly connected to one end of the second telescopic rod and the third spring. An upper limit sleeve is fixedly connected below the lower grab hook.

[0013] Preferably, the adjustable positioning assembly includes two second hydraulic devices, which are respectively fixedly installed below the two connecting parts. One end of each of the two second hydraulic devices is fixedly connected to a movable frame. Limit heads are fixedly connected to both the upper and lower sides of the movable frame, and the size of the limit heads is adapted to the size of the upper limit sleeve and the lower limit sleeve.

[0014] Preferably, the purification box is equipped with multiple partitions, and the purification components are separated by the partitions; The purification component includes an outer frame, with two first springs fixedly connected to the upper part of the outer frame. The top ends of the two first springs are fixedly connected to the top wall of the purification box. A high-efficiency activated carbon layer is installed on the outer frame, and two upper hooks are fixedly connected to the lower part of the outer frame.

[0015] Preferably, the inclined rail is fixedly connected to one side of the outer frame, and both the upper and lower ends of the inclined rail are provided with outlets.

[0016] A method for using a deodorizing device for pig farms includes the following steps: S1. When carrying out deodorization operations in pigsties, the odorous gas is introduced through spray deodorization equipment for preliminary deodorization. The odorous gas enters the purification box and is then purified through a high-efficiency activated carbon layer before being discharged from the purification box. S2. Secondly, the odor sensor can monitor the concentration of incoming odor. When the concentration is low, the motor drives the transmission shaft and transmission wheel to rotate, causing the transmission belt to drive the guide wheel to move horizontally, so that the guide wheel enters the inclined rail. The inclined surface of the inclined rail presses down on the outer frame, causing the high-efficiency activated carbon layer to enter the regeneration box downwards. This reduces the number of filters in the purification components and facilitates rapid filtration. When the odor concentration is high, the purification components are increased to perform multi-stage filtration. S3. When the high-efficiency activated carbon layer needs to be regenerated, the second hydraulic device drives the movable frame to move downward, so that the limit head engages with the lower limit sleeve. Then, the transmission component drives the guide wheel to move horizontally into the inclined rail, and the purification component is pressed down into the regeneration box through the inclined rail. The outer frame drives the first spring to deform, and at the same time, the upper hook squeezes the lower hook to drive the third spring to deform. When the upper hook and the lower hook are misaligned, the third spring drives the lower hook to lock with the upper hook, fixing the position of the purification component. When the guide wheel moves out from the outlet above the inclined rail, the guide wheel enters the next inclined rail, and the downward pushing operation of multiple purification components is carried out in sequence. S4. The purification component entering the regeneration box is transported by the conveying equipment and sprayed out by the nozzle group to regenerate the purification component. After the purification component is regenerated, the first hydraulic device drives the push plate to move, so that the push plate pushes the lower hook synchronously, so that the lower hook separates from the upper hook. At this time, the first spring drives the outer frame to reset upward, so that the high-efficiency activated carbon layer enters the purification box. S5. When the purification component is switched and regenerated, the second hydraulic device drives the movable frame to move upward, so that the limit head and the upper limit sleeve are engaged. At this time, when the downward-moving purification component drives the lower grab hook to squeeze the upper grab hook, multiple upper grab hooks are moved synchronously. At this time, under the action of the first spring reset, the purification component is driven upward into the purification box for purification operation, thereby performing the switching and regeneration operation.

[0017] Compared with the prior art, the present invention has the following beneficial effects.

[0018] 1. The deodorization device and method for pig farms apply force to the dual-control limiting component through the fixing and releasing component, causing the upper and lower grab hooks to separate. At this time, the purification component can smoothly enter the purification box to complete the return operation, allowing multiple rows of purification components to be combined in parallel, which can achieve multi-stage purification treatment of odor. Secondly, the transmission component drives the guide wheel into the inclined rail, allowing the guide wheel to press the purification component downward through the inclined rail, thereby reducing the use of purification components. This method can automatically adjust the combination of high-efficiency activated carbon layers according to the odor concentration detected by the odor sensor, which can not only meet the treatment of odor under different concentration conditions, but also avoid excessive use of high-efficiency activated carbon layers to avoid resource waste. Furthermore, the amount of high-efficiency activated carbon layers can be dynamically adjusted according to the actual air quality.

[0019] 2. The deodorization device and method for pig farms utilizes an adjustable positioning component that engages with the upper limit switch, connecting multiple dual-control limit components. The transmission component drives the guide wheel, which, in conjunction with the inclined rail, pulls the purification component downwards into the regeneration chamber. The upper and lower hooks then squeeze and separate the component, causing the high-efficiency activated carbon layer in the regeneration chamber to return to its original position. The second spring then resets, fixing the lower hooks in place. The conveying equipment then sprays regeneration liquid through nozzles, separating organic matter from the high-efficiency activated carbon layer for regeneration and ensuring its purification capacity. By switching purification components, the required purification effect can be guaranteed, and the regeneration process is automatic, requiring no downtime for maintenance.

[0020] 3. The deodorization device and method for pig farms utilizes an adjustable positioning component that engages with a lower limit sleeve. At this point, the transmission component drives the guide wheel, which, in conjunction with the inclined rail, pulls the purification component downwards into the regeneration tank. The purification component is then secured by a double-control limit component locking with an upper grab hook. The guide wheel is then sequentially moved into the inclined rail, allowing the purification components to be placed one by one into the regeneration tank. During placement, a conveying device, in conjunction with a spray nozzle assembly, continuously sprays regeneration liquid to desorb organic matter, achieving the purpose of regeneration. This method achieves efficient and deep regeneration of multiple rows of high-efficiency activated carbon layers, greatly improving the overall efficiency of the regeneration operation. Furthermore, a fixing and releasing component pushes the double-control component away from the lower grab hook. When the hook is engaged, the purification components can simultaneously return to their original position, facilitating odor purification. Secondly, by locking the adjustable positioning component upwards with the dual-control limit component, the purification components move downwards, causing the lower hook to move in conjunction with multiple dual-control limit components. This resets the purification components, originally in the regeneration chamber, upwards, achieving the switching purpose and ensuring the continuity and efficiency of the high-efficiency activated carbon layer purification process. This solution not only enables rapid switching of the high-efficiency activated carbon layer but also ensures that the high-efficiency activated carbon layer can automatically adjust its usage status under different operating conditions, thereby continuously guaranteeing the purification effect and significantly improving the continuous operation capability and overall stability of the equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0024] Example 1: Refer to Figures 1-5 and Figures 8-11 A deodorization device for pig farms includes a spray deodorization device 100. An odor sensor 101 is installed in the air inlet of the spray deodorization device 100. The spray deodorization device 100 can introduce odors from inside the pig house and perform initial spraying restart. The concentration of the odors entering can be monitored by the odor sensor 101. An odor purification and regeneration mechanism 200 is provided on one side of the spray deodorization device 100. The odor purification and regeneration mechanism 200 includes a purification box 201, in which multiple partitions 211 are installed. The purification components 203 can be separated by the partitions 211 and the airtightness is ensured. The purification components 203 are separated by the partitions 211. The purification component 203 includes an outer frame 2032. Two first springs 2033 are fixedly connected to the upper part of the outer frame 2032. The first springs 2033 can drive the outer frame 2032 to reset, thereby driving the high-efficiency activated carbon layer 2031 to reset upward. The tops of the two first springs 2033 are fixedly connected to the top wall of the purification box 201. The high-efficiency activated carbon layer 2031 is installed on the outer frame 2032. The high-efficiency activated carbon layer 2031 can purify the odor. After purification, the treated gas can be smoothly discharged because the purification box 201 has an exhaust port on the other side. The lower part of the outer frame 2032 is connected to two upper grabs. The cleaning box 201 is fixedly connected by hook 212. Multiple cleaning components 203 are installed inside the cleaning box 201. Two upper hooks 212 are connected to the bottom of the cleaning components 203. Inclined rails 210 are connected to both sides of the cleaning components 203. The inclined rails 210 are fixedly connected to one side of the outer frame 2032. The upper and lower ends of the inclined rails 210 are provided with outlets. Through the two outlets of the inclined rails 210, the guide wheel 213 can smoothly enter the inclined rails 210 and move out of the inclined rails 210. The guide wheel 213 can smoothly move to another inclined rail 210. The inclined design of the inclined rails 210 allows the guide wheel 213 to smoothly drive the inclined rails 210 to move downward when it moves horizontally. A regeneration component 202 is located below the purification chamber 201, and two side shells 204 are provided between the purification chamber 201 and the regeneration component 202. A transmission component 205 is housed within each side shell 204. The transmission component 205 includes two drive shafts 2053, which are rotatably mounted on the side shell 204 via bearings. One drive shaft 2053 is fixedly connected to the output shaft of a motor 2051, which is mounted on the purification chamber 201. A drive wheel 2054 is mounted on the drive shaft 2053, and the two drive wheels 2054 are connected by a transmission belt 2052. The transmission connection ensures the transmission effect of the transmission belt 2052 through two transmission wheels 2054, allowing the transmission belt 2052 to smoothly drive the guide wheel 213 to move horizontally and enabling the guide wheel 213 to achieve a reset through circular motion. The guide wheel 213 is mounted on the transmission belt 2052 and is connected to the transmission component 205. The transmission component 205 drives the guide wheel 213 to move horizontally, allowing the guide wheel 213 to smoothly enter the regeneration component 202 through the inclined rail 210 pressing down the purification component 203. The guide wheel 213 enters the inclined rail 210 pressing down the purification component 203 in sequence. The regeneration component 202 is equipped with two sets of lower limit sleeves 209, two adjustable positioning components 207, two fixing release components 206, and multiple parallel dual-control limit components 208. The fixing release component 206 includes two first hydraulic devices 2061, which are fixedly installed on the regeneration box 2021. One end of each first hydraulic device 2061 is fixedly connected to a push plate 2062. The adjustable positioning components 207 lock with the lower limit sleeves 209, so that the downward-pressed purification component 203 locks with the dual-control limit components 208 individually. After the adjustable positioning components 207 lock with the dual-control limit components 208 upward, the dual-control limit components 208 are connected together. At this time, the downward-adjusted purification components 203 switch up and down one by one.

[0025] In this embodiment: the first hydraulic device 2061 pushes the push plate 2062 to move, and the push plate 2062 applies force to the dual-control limit component 208, causing the upper hook 212 and the lower hook 2087 to separate. At this time, the first spring 2033 drives the outer frame 2032 to reset upward, so that the high-efficiency activated carbon layer 2031 completes the return operation, and the multiple rows of high-efficiency activated carbon layers 2031 are combined side by side, which can perform multi-stage purification treatment of odor. Next, the motor 2051 drives the transmission shaft 2053 and the transmission wheel 2054 to rotate, so that the transmission belt 2052 drives the guide wheel 213 into the inclined rail 210, so that the guide wheel 213 can press down on the outer frame 203 through the inclined rail 210. The high-efficiency activated carbon layer 2031 and the lower hook 2087 are offset downwards from the upper hook 212. The lower hook 2087 is reset by the third spring 2086, so that the upper hook 212 and the lower hook 2087 are locked together to fix the position of the purification component 203. This reduces the use of the high-efficiency activated carbon layer 2031. This method can automatically adjust the combination of high-efficiency activated carbon layer 2031 according to the odor concentration detected by odor sensor 101. It can not only meet the treatment of odor under different concentration conditions, but also avoid excessive use of high-efficiency activated carbon layer 2031 to avoid resource waste. Furthermore, the amount of high-efficiency activated carbon layer 2031 can be dynamically adjusted according to the actual air quality.

[0026] Example 2: Refer to Figures 5-7A deodorization device for pig farms includes a regeneration component 202, which includes a regeneration box 2021. The regeneration box 2021 is fixedly connected to a side shell 204 and a purification box 201. A conveying device 2023 is installed on one side of the regeneration box 2021. The conveying device 2023 is connected to a conveying pipe 2022 and a three-way valve 2025. The three-way valve 2025 can be connected to an external pipe to convey regenerated liquid into the regeneration box 2021. The three-way valve 2025 can also be used to extract liquid from the regeneration box 2021, thereby enabling circulation. The conveying device 2023 conveys the regenerated liquid and sprays it out through a nozzle assembly 2024, which allows the regenerated liquid to flow and facilitates the regeneration of the high-efficiency activated carbon layer 2031. The three-way valve 2025 is connected to the regeneration box 2021, and both ends of the conveying pipe 2022 are connected to two nozzle assemblies 2024, which are installed in the regeneration box 2021. The dual-control limiting component 208 includes a fixing plate 2081, which is fixedly connected to the bottom wall of the regeneration box 2021. A first telescopic rod 2082 and a second spring 2083 are fixedly connected to both sides of the fixing plate 2081. When the upper limiting sleeve 2088 engages with the limiting head 2073, the second spring 2083 drives the lower grab hook 2087 to lock with the upper grab hook 212, thereby fixing the position of the purification component 203. A connecting piece 208 is fixedly connected to one end of the first telescopic rod 2082 and the second spring 2083. 4. A second telescopic rod 2085 and a third spring 2086 are fixedly connected to one side of the connector 2084. The third spring 2086 can drive the upper hook 212 and the lower hook 2087 to engage, ensuring the stability of the purification component 203. A lower hook 2087 is fixedly connected to one end of the second telescopic rod 2085 and the third spring 2086. An upper limit sleeve 2088 is fixedly connected below the lower hook 2087. There are multiple lower limit sleeves 209 in each group, and the lower limit sleeves 209 are fixedly connected to the bottom wall of the regeneration box 2021. The adjustable positioning component 207 includes two second hydraulic devices 2071, which are fixedly installed below the two connectors 2084. One end of each of the two second hydraulic devices 2071 is fixedly connected to a movable frame 2072. The second hydraulic devices 2071 drive the limiting head 2073 to engage with the lower limiting sleeve 209, which ensures the smooth use of the third spring 2086. The restoring force of the third spring 2086 locks the lower grab hook 2087 and the upper grab hook 212. When the limiting head 2073 engages with the upper limiting sleeve 2088, multiple lower grab hooks 2087 are connected together, allowing the second spring 2083 to be used smoothly and ensuring the switching of the purification component 203. The upper and lower sides of the movable frame 2072 are fixedly connected to the limiting head 2073, and the size of the limiting head 2073 is adapted to the size of the upper limiting sleeve 2088 and the lower limiting sleeve 209.

[0027] In this embodiment: the second hydraulic device 2071 drives the movable frame 2072 to move upward, causing the limiting head 2073 to engage with the upper limiting sleeve 2088, connecting multiple upper grab hooks 212 together. At this time, the transmission component 205 drives the guide wheel 213 to move, so that the guide wheel 213, in conjunction with the inclined rail 210, can drive the purification component 203 downward into the regeneration box 2021. After being squeezed and staggered by the upper grab hooks 212 and the lower grab hooks 2087, the purification component 203, which was originally in the regeneration box 2021, returns to its original position. At this time, the second spring 2083 resets, allowing the upper hook 212 and lower hook 2087 to fix the purification component 203 that has just moved down. At this time, the conveying device 2023 sprays regeneration liquid through the nozzle group 2024 to flow, which can remove organic matter from the high-efficiency activated carbon layer 2031, making it easy to regenerate and use the high-efficiency activated carbon layer 2031, and ensuring the purification capacity of the high-efficiency activated carbon layer 2031. Furthermore, by switching the high-efficiency activated carbon layer 2031, the actual required purification effect can be guaranteed, and the regeneration operation can be automatically realized without stopping maintenance.

[0028] Example 3: Reference Figures 2-4 , Figure 8 and Figure 10 A deodorization device for pig farms includes an odor purification and regeneration mechanism 200. The odor purification and regeneration mechanism 200 includes a purification box 201. The purification box 201 is equipped with multiple purification components 203. Two upper hooks 212 are connected to the bottom of the purification components 203. Inclined rails 210 are connected to both sides of the purification components 203. Below the purification box 201, a regeneration component 202 is provided, and two side shells 204 are also provided between the purification box 201 and the regeneration component 202. A transmission component 205 is provided in the side shell 204, and a guide wheel 213 is connected to the transmission component 205. The transmission component 205 drives the guide wheel 213 to move horizontally, so that the guide wheel 213 presses down on the purification component 203 through the inclined rail 210 and smoothly enters the regeneration component 202, so that the guide wheel 213 enters the inclined rail 210 in sequence to press down on the purification component 203. The regeneration component 202 is equipped with two sets of lower limit sleeves 209, two adjustable positioning components 207, two fixing release components 206, and multiple parallel dual-control limit components 208. By locking the adjustable positioning components 207 with the lower limit sleeves 209, the downward-pressed purification component 203 is individually locked with the dual-control limit component 208. After the adjustable positioning components 207 are locked upward with the dual-control limit components 208, the dual-control limit components 208 are connected together. At this time, the downward-pressed purification components 203 are switched up and down one by one.

[0029] In this embodiment: the adjustable positioning component 207 engages with the lower limit sleeve 209, at which point the transmission component 205 drives the guide wheel 213 to cooperate with the inclined rail 210 to drive the purification component 203 downward into the regeneration box 2021. The purification component 203 is then locked and fixed by the dual-control limiting component 208 and the upper grab hook 212. Then, the guide wheel 213 is sequentially driven into the inclined rail 210, allowing the purification components 203 to be placed one by one into the regeneration box 2021. During the placement process, the conveying device 2023, in conjunction with the nozzle assembly 2024, sprays the regeneration liquid to desorb organic matter, achieving the purpose of regeneration. This method realizes the efficient and deep regeneration of multiple rows of high-efficiency activated carbon layers 2031, greatly improving the overall efficiency of the regeneration operation. Furthermore, the fixing and releasing component 206 drives the dual-control assembly... When the component disengages from the lower gripper 2087, the purification component 203 can simultaneously return to its original position, facilitating odor purification. Secondly, by locking the adjustable positioning component 207 upwards with the dual-control limit component 208, the purification component 203 moves downwards, causing the lower gripper 2087 to move in conjunction with multiple dual-control limit components 208. This allows the purification component 203, originally in the regeneration box 2021, to return to its original position, thus achieving the switching purpose. This ensures the continuity and efficiency of the purification process of the high-efficiency activated carbon layer 2031. This solution not only enables rapid switching of the high-efficiency activated carbon layer 2031 but also ensures that the high-efficiency activated carbon layer 2031 can automatically adjust its usage status under different operating conditions, thereby continuously guaranteeing the purification effect and significantly improving the continuous operation capability and overall stability of the equipment.

[0030] A method for using a deodorizing device for pig farms includes the following steps: S1. When carrying out deodorization operations in pigsties, odorous gas is introduced through spray deodorization equipment 100 for preliminary deodorization operations. The odorous gas enters the purification box 201 and is then purified by the high-efficiency activated carbon layer 2031 before being discharged from the purification box 201. S2. Secondly, the odor sensor 101 can monitor the concentration of incoming odor. When the concentration is low, the motor 2051 drives the transmission shaft 2053 and the transmission wheel 2054 to rotate, causing the transmission belt 2052 to drive the guide wheel 213 to move horizontally. The guide wheel 213 enters the inclined rail 210, and the inclined surface of the inclined rail 210 presses down on the outer frame 2032, causing the high-efficiency activated carbon layer 2031 to enter the regeneration box 2021 downwards. This reduces the number of filters in the purification component 203, making it easier to filter quickly. When the odor concentration is high, the purification component 203 is increased to perform multi-stage filtration. S3. When the high-efficiency activated carbon layer 2031 needs to be regenerated, the second hydraulic device 2071 drives the movable frame 2072 to move downward, so that the limit head 2073 engages with the lower limit sleeve 209. Then, the transmission component 205 drives the guide wheel 213 to move horizontally into the inclined rail 210, and the purification component 203 is pressed down into the regeneration box 2021 through the inclined rail 210. The outer frame 2032 drives the first spring 2033 to deform, and at the same time, the upper hook 212 squeezes the lower hook 2087 to drive the third spring 2086 to deform. When the upper hook 212 and the lower hook 2087 are misaligned, the third spring 2086 drives the lower hook 2087 to lock with the upper hook 212, fixing the position of the purification component 203. When the guide wheel 213 moves out from the outlet above the inclined rail 210, the guide wheel 213 enters the next inclined rail 210, and the downward pushing operation of multiple purification components 203 is carried out in sequence. S4. The purification component 203 enters the regeneration box 2021. The regeneration liquid is conveyed by the conveying equipment 2023 and sprayed out by the nozzle group 2024 to regenerate the purification component 203. After the purification component 203 is regenerated, the first hydraulic device 2061 drives the push plate 2062 to move, so that the push plate 2062 pushes the lower grab hook 2087 in sync, so that the lower grab hook 2087 separates from the upper grab hook 212. At this time, the first spring 2033 drives the outer frame 2032 to reset upward, so that the high-efficiency activated carbon layer 2031 enters the purification box 201. S5. When the purification component 203 is switching and regenerating, the second hydraulic device 2071 drives the movable frame 2072 to move upward, so that the limit head 2073 engages with the upper limit sleeve 2088. At this time, when the downward-moving purification component 203 drives the lower grab hook 2087 to squeeze with the upper grab hook 212, multiple upper grab hooks 212 are moved synchronously. At this time, under the reset action of the first spring 2033, the purification component 203 is driven upward into the purification box 201 for purification operation, thereby performing the switching and regeneration operation.
