Description

Technical Field

[0001] This invention relates to the field of chlorine treatment and environmental protection equipment technology, and in particular to a chlorine environmental purification device. Background Technology

[0002] Chlorine, a commonly used chemical raw material in industrial production, is widely used in chemical synthesis, wastewater treatment, metallurgy, papermaking, and other fields. However, chlorine produced in industrial processes or emitted as exhaust gas often contains dust, soluble impurities, trace amounts of sulfides, and organic pollutants, making it impossible to directly meet emission standards or recycle. It needs to be purified by a dedicated purification device to remove various impurities and meet environmental protection standards. Currently, the industry's conventional chlorine purification process mainly uses a combination of water washing and spraying with packing adsorption. The purification liquid is sprayed by the spraying mechanism and comes into countercurrent contact with the chlorine to initially remove soluble impurities and particulate matter. Then, the packing layer deeply adsorbs trace harmful components, achieving environmentally friendly purification of chlorine.

[0003] Existing chlorine purification devices suffer from significant core technical defects during long-term continuous operation. Dust, impurities, and crystals from the spray liquid carried by the chlorine easily adhere to and clog the spray head orifices, resulting in uneven spraying, reduced flow, insufficient contact between chlorine and the purification liquid, and a sharp drop in water washing and impurity removal efficiency. This easily leads to substandard purification and excessive exhaust gas. Furthermore, cleaning the clogged spray mechanism is extremely difficult. Traditional cleaning methods rely on shutdown, disassembly, and manual cleaning, which not only interrupts the production process and affects operational continuity, but also poses a risk of leakage and poisoning accidents due to close contact with residual chlorine. Uneven manual cleaning makes it difficult to completely remove foreign objects from the spray orifices, and repeated operation accelerates the wear and tear of the spray components. Most existing devices lack dedicated offline cleaning structures for the spray components, and some are only equipped with simple flushing pipes, which can only achieve single-flow rinsing and cannot effectively remove stubborn dirt. Summary of the Invention

[0004] The technical problem to be solved by this invention is that the existing technology has drawbacks such as low degree of automation, incomplete cleaning, great safety hazards and cumbersome operation and maintenance. To this end, we propose an environmentally friendly chlorine purification device.

[0005] To achieve the above objectives, this application employs the following chlorine purification device, comprising a sedimentation tank, two sets of tower tubes installed at the top of the sedimentation tank, a spraying mechanism installed inside each set of tower tubes, the spraying mechanism spraying washing liquid to purify chlorine, packing material fixedly connected to the bottom of the inner wall of the tower tubes, a shell provided on one side of each set of tower tubes, a spraying mechanism installed at the bottom of the inner wall of the shell, and also including a brush plate and comb strips;

[0006] The shell is equipped with a spray uniform mechanism, which moves the spray mechanism into the shell and uses water flow to continuously rinse the bottom surface of the spray mechanism to clean the dirt adsorbed on the surface of the spray mechanism after long-term use and the foreign objects blocked inside the spray mechanism, so as to ensure the uniformity of the spray water mist. Then the spray mechanism is deflected 90 degrees to a vertical position, ready for subsequent brushing. The whole process is sealed and there is no chlorine gas leakage, and the purification process is not interrupted.

[0007] The auxiliary purification mechanism, after the spray uniform mechanism is in place, drives the brush plate forward to approach the working surface of the spray mechanism, so as to achieve a tight fit between the brush plate and the surface of the spray mechanism, ensure the alignment accuracy and avoid component interference, stabilize the cleaning pressure, and adapt to the continuous operation requirements of the chlorine purification equipment.

[0008] The purification guarantee mechanism enables the brush plate to rotate and adhere to the surface of the spray mechanism for brushing. By using the friction between the brush plate and the spray mechanism, combined with water rinsing, the uniform spray state is quickly restored, the gas-liquid contact efficiency between chlorine and the purification liquid is improved, and the purification effect of chlorine water washing is guaranteed.

[0009] The operation and maintenance frequency reduction mechanism is connected to the purification support mechanism so that the brush plate rotates half a circle and then repeatedly extends and retracts. During the extension and retraction, it works with the comb to remove the dirt adsorbed inside the brush plate, realizing automatic self-cleaning of the cleaning brush. Impurities are discharged with the water flow, avoiding secondary adhesion and recurrence of blockage, and reducing the operation and maintenance frequency of the chlorine purification device.

[0010] Preferably, the uniform spraying mechanism includes:

[0011] Two lead screws are installed on both sides of the inner wall of the housing. A motor is installed at one end of each lead screw. Long plates are installed on both sides of the inner wall of the housing. The surfaces of the long plates have horizontal grooves and arc grooves. A rotating shaft plate is installed on both sides of the spraying mechanism. A guide plate is rotatably connected to one side of the rotating shaft plate. A slider is fixedly connected to one end of the rotating shaft plate. The guide plate is slidably connected to the inner wall of the horizontal groove. The slider is slidably connected to the inner walls of the horizontal groove and the arc groove. A moving plate is engaged with the surface of the lead screw. The surface of the moving plate has a guide groove. The slider is slidably connected to the inner wall of the guide groove. A water curtain nozzle is installed at the bottom of the inner wall of the housing.

[0012] Preferably, the auxiliary purification mechanism includes:

[0013] Two gears are rotatably connected to one side of a long plate. A first toothed plate is fixedly connected to one side of the top of the movable plate. Limiting plates are fixedly connected to both sides of the inner wall of the housing. A frame plate is slidably connected inside the limiting plate. A second toothed plate is fixedly connected to both sides of the frame plate. One side of the second toothed plate meshes with the surface of the gear. The surface of the first toothed plate meshes with the surface of the gear. Springs are fixedly connected to both sides of the frame plate. The other end of the springs is fixedly connected to the inner wall of the housing.

[0014] Preferably, the purification guarantee mechanism includes:

[0015] The motor is fixedly connected to one side of the frame plate. The output end of the motor is fixedly connected to a hollow sliding column. A hollow column is slidably connected to the surface of the hollow sliding column. The front end of the hollow column is fixedly connected to a brush plate. A water curtain nozzle is installed on the top of the inner wall of the housing.

[0016] Preferably, the operation and maintenance frequency reduction mechanism includes:

[0017] The frame has the comb bar fixedly connected to the inner wall of the frame, a four-bar disc fixedly connected to one side of the brush plate, the frame slidably connected to the four-bar disc around the perimeter, a sleeve fixedly connected to the front end of the frame plate, a protruding column fixedly connected to the inner wall of the sleeve, a circumferential groove opened on the surface of the hollow column, the four-bar disc rotatably connected to the surface of the sleeve, and the frame rotatably connected to the front end of the frame plate.

[0018] Preferably, the distance between one end of the transverse groove and the top of the arc groove is equal to the distance between the middle of the guide plate and the slider.

[0019] Preferably, the guide groove has an obtuse angle structure, the bottom of the guide groove is a straight groove, the side of the guide groove is an inclined groove, the horizontal span of the inclined groove is equal to the distance between one end of the horizontal groove and the top of the arc groove, and the height of the guide groove is equal to the height from the bottom of the arc groove to the horizontal groove.

[0020] Preferably, the upper half of the surrounding groove is a V-shaped structure opened around the surface of the hollow column, and the lower half is a semi-circular structure opened around the surface of the hollow column, with the two ends of the V-shaped structure connected to the semi-circular structure.

[0021] The technical effects and advantages of this invention are as follows:

[0022] In this invention, when impurities adhere to the bottom of the spray mechanism and the spray holes, or when gaps are blocked, the chlorine input is stopped, and the motor is started to drive the lead screw to rotate and drive the moving plate to move laterally. This, in turn, pushes the slider and guide plate to slide directionally along the straight groove of the long plate, smoothly moving the spray mechanism out of the tower tube working area to the cleaning station inside the shell. When the spray mechanism passes the spraying mechanism, the spraying mechanism automatically switches to high-pressure water flow mode to initially flush its surface and spray holes, removing loose dirt and foreign objects. After the spray mechanism is completely moved into the shell, the slider completes a 90-degree vertical deflection along the arc groove, so that the working surface of the spray mechanism and the cleaning parts are precisely aligned. The entire process of moving and adjusting the posture is automated, eliminating the need for manual disassembly and cleaning, preventing the safety risks caused by chlorine leakage, and enabling fully enclosed automated operation. This meets environmental and safety production standards, effectively reducing manual maintenance costs and operational hazards, and ensuring the continuous and efficient operation of chlorine purification.

[0023] In this invention, after the spray mechanism shifts laterally and deflects vertically into position, the moving plate continues to move slightly, driving the gear to rotate via the first toothed plate. The gear meshes with the second toothed plate, driving the frame plate to slide directionally along the limiting plate, simultaneously stretching the spring to store energy. This causes the brush plate and comb to smoothly approach the working surface of the spray mechanism, achieving a tight fit and laying the foundation for subsequent deep cleaning. After the cleaning operation is completed, the lead screw rotates in the opposite direction, causing the moving plate to reset. First, it pulls the frame plate and brush plate backward to avoid them, then drives the spray mechanism to reset, deflect, and move back to the working position inside the tower tube. The spring rebounds, ensuring the frame plate accurately returns to its original position. This purely mechanical linkage structure does not require the addition of independent drive components. It has a compact structure and stable and reliable transmission, effectively avoiding collisions and interference between the spray mechanism and the cleaning components during the attitude change process. It ensures the alignment accuracy and uniformity of the bonding force, guaranteeing both the cleaning effect and preventing damage to the spray mechanism due to excessive compression, thus improving the overall operational stability of the device.

[0024] In this invention, after the brush plate is tightly attached to the surface of the spray mechanism, the purification guarantee mechanism is activated, driving the motor to rotate the hollow sliding column, which in turn drives the hollow column and the brush plate to rotate synchronously. The brush plate closely adheres to the spray holes and working surface of the spray mechanism, performing circumferential friction to precisely remove stubborn dirt and clogging impurities. At the same time, the water curtain nozzle at the top of the shell continuously sprays water, simultaneously rinsing the spray mechanism and brush plate from top to bottom, quickly washing away the detached dirt and preventing secondary adhesion. Through the dual action of mechanical friction and water rinsing, the spray holes of the spray mechanism can be thoroughly unblocked, restoring the uniform spray state of water mist. Compared with single water rinsing or manual cleaning, the cleaning power is stronger and the effect is more thorough. It effectively solves the problem of insufficient contact between chlorine and water washing liquid and reduced purification efficiency caused by the blockage of the spray mechanism, ensuring the stable operation of the chlorine water washing and impurity removal and deep adsorption process of the packing, improving the purity of chlorine purification, meeting environmental emission and recycling standards, and extending the overall service life of the device.

[0025] In this invention, the hollow column surface groove cooperates with the protruding column on the inner wall of the sleeve to drive the brush plate to achieve a compound motion of half-circle self-rotation brushing and half-circle reciprocating extension. When the brush plate retracts, the comb strips inside the frame come into close contact with the brush plate, combing and removing residual dirt and impurities adsorbed inside the brush plate. With the continuous water flow from the water curtain nozzle, the detached impurities are discharged from the shell with the water flow, completing the fully automatic self-cleaning of the brush plate. This mechanism operates synchronously with the cleaning operation without additional control commands, effectively solving the problems of dirt residue on the cleaning components and the decline in cleaning efficiency due to repeated use. It ensures that the brush plate always maintains the optimal cleanliness state, eliminating the need for separate manual maintenance, further realizing the fully automated operation and maintenance of the device, reducing the frequency of later maintenance, ensuring the long-term stable operation of the device, and reducing the overall operating cost.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0034] Reference Figures 1-6 As shown, the present invention provides an environmentally friendly chlorine purification device, including a sedimentation tank 1, two sets of tower tubes 2 installed on the top of the sedimentation tank 1, a spraying mechanism 3 installed inside each set of tower tubes 2, the spraying mechanism 3 sprays washing liquid to purify chlorine, packing 4 is fixedly connected to the bottom of the inner wall of the tower tubes 2, a shell 5 is provided on one side of each set of tower tubes 2, a spraying mechanism 6 is installed at the bottom of the inner wall of the shell 5, and also includes a brush plate 7 and a comb 8.

[0035] The shell 5 is equipped with a uniform spraying mechanism to clean the dirt adsorbed on the surface of the spraying mechanism 3 after long-term use and the foreign objects clogging the inside of the spraying mechanism 3, so as to ensure the uniformity of the spraying water mist. Then the spraying mechanism 3 is deflected ninety degrees to a vertical position, ready for subsequent brushing. The whole process is sealed and there is no chlorine gas leakage, so the purification process is not interrupted.

[0036] Reference Figures 1-3 As shown in this embodiment, the uniform spraying mechanism includes:

[0037] Two lead screws 9 are installed on both sides of the inner wall of the housing 5. A motor 10 is installed at one end of each lead screw 9. Long plates 11 are installed on both sides of the inner wall of the housing 5. Horizontal grooves 12 and arc grooves 13 are formed on the surface of each long plate 11. A rotating shaft 14 is installed and connected to both sides of the spraying mechanism 3. A guide plate 15 is rotatably connected to one side of the rotating shaft 14. A slider 16 is fixedly connected to one end of the rotating shaft 14. The guide plate 15 is slidably connected to the inner wall of the horizontal groove 12. The slider 16 is slidably connected to the inner walls of the horizontal groove 12 and the arc groove 13. A movable plate 17 is engaged with the surface of the lead screw 9. The surface of the movable plate 17 has... There is a guide groove 18, and a slider 16 is slidably connected to the inner wall of the guide groove 18. Chlorine gas is introduced through the bottom of the tower tube 2 and flows slowly upward through the packing 4. Then, the chlorine gas is sprayed by the spraying mechanism 3 to perform preliminary water washing, which removes most of the soluble impurities and some particulate pollutants carried in the chlorine gas. After the preliminary water washing, the chlorine gas enters the upper purification chamber and comes into contact with the purification and adsorption materials inside the packing 4. The packing 4 will deeply adsorb and remove the trace organic impurities, sulfides and heavy metal impurities remaining in the chlorine gas, ensuring that the purity of the chlorine gas meets the environmental protection requirements for industrial emission and reuse. Finally, the gas flows to the top of the tower tube 2 and is discharged.

[0038] During the long-term operation of the device, particulate impurities continuously accumulate on the bottom surface of the spray mechanism 3. Some impurities will also adhere to the gaps in the spray head with the airflow, causing the spray mist distribution of the spray mechanism 3 to become uneven, reducing the contact area between chlorine and spray water, and decreasing the water washing and impurity removal effect.

[0039] At this point, the motor 10 can be started to drive the lead screw 9 to rotate, causing the lead screw 9 to move the moving plate 17 on the surface to the other side. This causes the moving plate 17 to move laterally through the guide groove 18, pushing the slider 16 and the guide plate 15 to slide laterally along the inner wall of the transverse groove 12. This allows the shaft rotating plate 14 and the spraying mechanism 3 to follow the guide plate 15 and the slider 16 to move laterally along the straight trajectory of the transverse groove 12, moving the spraying mechanism 3 out of the tower tube 2 and into the shell 5. During this process, the spraying mechanism 6 starts to operate, spraying water upwards. When the spraying mechanism 3 passes the top of the spraying mechanism 6, it is cleaned by the water flow. The surface is washed to remove most of the foreign matter. Then the spray mechanism 3 is moved away from the top of the spray mechanism 6 and the spray mechanism 6 stops operating. At this time, the guide plate 15 has completely moved to the other end of the horizontal groove 12 and can no longer move forward. The slider 16 is also at the top entrance of the arc groove 13. At this time, the lead screw 9 drives the moving plate 17 to continue to move forward, which will cause the guide groove 18 to push the slider 16 downward and then deflect it ninety degrees along the inner wall of the arc groove 13. This causes the spray mechanism 3 to deflect from the downward state to the vertical state, which makes the working surface of the spray mechanism 3 aligned with the brush plate 7. Then, deep cleaning is performed through the brush plate 7.

[0040] The tower tube 2 has a semi-circular opening in the middle to allow the spray mechanism 3 to be moved out of the tower tube 2. The spray mechanism 3 has a sealing ring on one side that corresponds to the other side of the tower tube 2. When the spray mechanism 3 is reset to the inside of the tower tube 2, the two sealing rings merge to seal the gap between the tower tube 2 and the spray mechanism 3, effectively preventing the airflow inside the device from leaking out of the gap, ensuring the pressure inside the device is stable, and preventing unpurified chlorine gas from leaking and polluting the surrounding air.

[0041] After deep cleaning is completed, the lead screw 9 drives the moving plate 17 to move in the opposite direction. First, it will drive the slider 16 to deflect upwards by 90 degrees to reset. Then, it will continue to pull the slider 16, guide plate 15 and spray mechanism 3 to move in the opposite direction, sending the cleaned spray mechanism 3 back into the tower tube 2 to continue working. The entire cleaning process does not require stopping the machine to disassemble the device, and does not require manual entry into the tank for cleaning. This will not delay the progress of chlorine purification operation, and also avoids the risk of chlorine leakage and poisoning that may occur during manual cleaning.

[0042] Furthermore, when the spraying mechanism 3 moves out to the working area of ​​the spraying mechanism 6, the spraying water path of the spraying mechanism 6 will switch to high-pressure water supply mode. The high-pressure water flow will flush the spraying mechanism 3 from inside the spray head, directly washing away the impurities stuck in the gaps of the spraying mechanism 3 and carrying them out of the device along the drainage channel, completing the automatic unblocking of the spray head, allowing the spray water mist to be evenly distributed again, ensuring that chlorine and spray water can fully contact each other, and keeping the water washing and impurity removal effect in a stable state. The entire device achieves self-cleaning maintenance, reducing the frequency of manual operation and maintenance and safety risks, and also extending the continuous operation time of the device, improving the overall efficiency of chlorine purification, and being more in line with environmentally friendly production.

[0043] Furthermore, refer to Figure 4 As shown in this embodiment, the distance between one end of the transverse groove 12 and the top of the arc groove 13 is equal to the distance between the middle of the guide plate 15 and the slider 16. By matching the distances of the two, the slider 16 and the guide plate 15 can accurately achieve the specified angle deflection of the spray mechanism 3 after they are in place, and the stability of the spray mechanism 3 during movement is ensured. This avoids the shaking and deflection errors of the spray mechanism 3 during movement. It can accurately move to the preset cleaning position and align with the purification guarantee mechanism every time, without misalignment that would cause incomplete cleaning. At the same time, the precise matching of the distances can also reduce unnecessary wear of parts during the operation of the device, extend the service life of the transmission parts, and reduce the cost of later maintenance and replacement of parts.

[0044] Furthermore, refer to Figure 4 As shown in this embodiment: the guide groove 18 has an obtuse angle structure, the bottom of the guide groove 18 is a straight groove, and the side of the guide groove 18 is an inclined groove. The horizontal span of the inclined groove of the guide groove 18 is equal to the distance between one end of the horizontal groove 12 and the top of the arc groove 13, and the height of the guide groove 18 is equal to the height from the bottom of the arc groove 13 to the horizontal groove 12. With the guide design of the obtuse angle structure, when the slider 16 slides into the straight groove along the inclined groove of the guide groove 18, it can adjust its position naturally along the slope without any jamming or sticking. At the same time, the top of the inclined groove, together with the straight groove of the horizontal groove 12, can accurately guide the slider 16 to move laterally, and the bottom of the straight groove can also restrict the slider 16 from deflecting in the opposite direction when it is at the bottom of the arc groove 13, further ensuring the accuracy of the transmission positioning.

[0045] Furthermore, the chlorine environmental purification device also includes an auxiliary purification mechanism. After the spray uniform mechanism is in place, the auxiliary purification mechanism drives the brush plate 7 forward to approach the working surface of the spray mechanism 3, so as to achieve a tight fit between the brush plate 7 and the surface of the spray mechanism 3, ensuring alignment accuracy and avoiding component interference, stabilizing cleaning pressure, and adapting to the continuous operation requirements of the chlorine purification equipment.

[0046] Specifically, refer to Figures 1-6 As shown in this embodiment, the auxiliary purification unit includes:

[0047] Two gears 20 are rotatably connected to one side of the long plate 11. A first toothed plate 21 is fixedly connected to one side of the top of the movable plate 17. Limiting plates 22 are fixedly connected to both sides of the inner wall of the housing 5. A frame plate 23 is slidably connected inside the limiting plate 22. A second toothed plate 24 is fixedly connected to both sides of the frame plate 23. One side of the second toothed plate 24 meshes with the surface of the gear 20, and the surface of the first toothed plate 21 meshes with the surface of the gear 20. Springs 28 are fixedly connected to both sides of the frame plate 23, and the other end of the springs 28 is fixed to the inner wall of the housing 5. When the spray mechanism 3 moves into the housing 5 and deflects, the spray mechanism 3 and the brush plate 7 are vertically aligned, and the slider 16 is completely placed at the bottom of the arc groove 13. However, the motor 10 continues to drive the lead screw 9 to rotate, which causes the moving plate 17 to continue to move forward. The slider 16 is placed at the bottom of the arc groove 13 and in the straight groove at the bottom of the guide groove 18. At this time, the forward movement of the moving plate 17 will cause the slider 16 to slide into the guide groove 18. At this time, the movement of the moving plate 17 will not cause the slider 16 to slide. The slider 16 will remain stationary on the inner wall of the arc groove 13.

[0048] As the moving plate 17 moves forward, the first toothed plate 21 meshes with the gear 20. The first toothed plate 21 will push the gear 20 to rotate and move the second toothed plate 24 on the other side, so that the gear 20 rotates and drives the second toothed plate 24 to move closer to the spray mechanism 3. During this process, the frame plate 23 moves synchronously with the second toothed plate 24 and slides along the limiting plate 22. The rear end of the frame plate 23 will also pull the spring 28 to extend and store force, so that the frame plate 23 drives the brush plate 7 and the comb 8 to move closer to the surface of the spray mechanism 3, so that the brush plate 7 is ready to rotate and brush for deep cleaning.

[0049] After the brush plate 7 finishes brushing, the motor 10 drives the lead screw 9 to move the moving plate 17 back to its original position. It also first drives the gear 20 to rotate through the first toothed plate 21, thereby moving the second toothed plate 24 back to its original position. When the moving plate 17 moves backward and the slider 16 slides to the bottom of the inclined groove of the guide groove 18, the guide groove 18 will then push the slider 16 and the spray mechanism 3 to reset and deflect. Then, it will move laterally back to the inside of the tower tube 2 for normal use. The spring 28 is used to ensure the initial position of the frame plate 23 and the stability of the meshing between the second toothed plate 24 and the gear 20. The spring 28 always maintains a pulling force on the frame plate 23, so that the gear 20 can always maintain the meshing state with the second toothed plate 24 when it is not pushed by the first toothed plate 21, so that the second toothed plate 24 will not easily slide close to the spray mechanism 3.

[0050] Furthermore, the chlorine environmental purification device also includes a purification support mechanism. The purification support mechanism enables the brush plate 7 to rotate and adhere to the surface of the spray mechanism 3 for brushing. By using the friction between the brush plate 7 and the spray mechanism 3, combined with water rinsing, the uniform spray state is quickly restored, improving the gas-liquid contact efficiency between chlorine and the purification liquid, and ensuring the chlorine water washing purification effect.

[0051] Specifically, refer to Figure 5 and Figure 6 As shown in this implementation plan, the purification support mechanism includes:

[0052] Motor 25 is fixedly connected to one side of frame plate 23. A hollow sliding column 26 is fixedly connected to the output end of motor 25. A hollow column 27 is slidably connected to the surface of the hollow sliding column 26. The front end of the hollow column 27 is fixedly connected to the brush plate 7. When the spray mechanism 3 deflects and moves to the state of being aligned with the brush plate 7, the brush plate 7 also moves closer to the surface of the spray mechanism 3. Then motor 25 starts running, driving the hollow sliding column 26 to rotate. The hollow sliding column 26 slides and extends along the inner wall of the hollow column 27. When the hollow sliding column 26 rotates, the hollow column 27 will also be driven to rotate. Since the hollow column 27 is fixed to the brush plate 7, the brush plate 7 itself also rotates and adheres to the spray nozzle on the surface of the spray mechanism 3 for brushing, so as to clean the dirt and blockage at the spray nozzle of the spray mechanism 3 by friction.

[0053] After cleaning is completed, motor 25 stops running, and lead screw 9 drives spray mechanism 3 to retract and reset. Brush plate 7 will follow and leave first, without interfering with the deflection and reset of spray mechanism 3. By automatically cleaning the nozzle position of spray mechanism 3, long-term accumulated impurities are prevented from clogging the nozzles and affecting the uniformity of subsequent chlorine gas introduction. Compared with the traditional manual cleaning method, it does not require operators to open the device valve body and operate by hand, which reduces the intensity of manual labor and avoids the harm to the operator's body caused by residual chlorine gas leakage, further improving the environmental protection and safety of the device operation.

[0054] Furthermore, the chlorine purification device also includes a frequency reduction mechanism for operation and maintenance. The frequency reduction mechanism is connected to the purification support mechanism, so that the brush plate 7 rotates half a circle and then repeatedly extends and retracts. During the extension and retraction, it works with the comb 8 to remove the dirt adsorbed inside the brush plate 7, thus achieving automatic self-cleaning of the cleaning brush. Impurities are discharged with the water flow, avoiding secondary adhesion and recurrence of blockage, and reducing the frequency of operation and maintenance of the chlorine purification device.

[0055] Specifically, refer to Figure 5 and Figure 6 As shown in this implementation plan, the frequency reduction and maintenance organization includes:

[0056] The frame 29 has comb bars 8 fixedly connected to the inner wall of the frame 29. A four-bar disc 30 is fixedly connected to one side of the brush plate 7. The frame 29 is slidably connected to the four-bar disc 30. A sleeve 31 is fixedly connected to the front end of the frame plate 23. A protruding column 32 is fixedly connected to the inner wall of the sleeve 31. A surrounding groove 33 is opened on the surface of the hollow column 27. The four-bar disc 30 is rotatably connected to the surface of the sleeve 31. The frame 29 is rotatably connected to the front end of the frame plate 23. When the motor 25 runs and drives the hollow sliding column 26 to rotate, the hollow sliding column 26 drives the hollow column 27 and the brush plate 7 to rotate. When the hollow column 27 rotates, it rotates along the inner wall of the sleeve 31. The protruding column 32 slides along the surrounding groove 33 on the surface of the hollow column 27, so that the hollow column 27 is restricted by the protruding column 32 each time it rotates. By guiding the surrounding groove 33 through the protruding column 32, the hollow column 27 rotates one revolution. Half of the revolution is in the normal rotation state, and the second half of the revolution is in the telescopic movement state.

[0057] This means that the hollow column 27 drives the brush plate 7 to be in contact with the spray mechanism 3 for half a turn each time it rotates, and then moves back and forth to reset and continue brushing. When the brush plate 7 rotates, the four-bar disc 30 rotates synchronously with the brush plate 7. The four-bar disc 30 drives the frame 29, which slides on the surface, to rotate synchronously with the brush plate 7. The position of the frame 29 is limited by the frame plate 23 and cannot move, so it can only rotate.

[0058] When the brush plate 7 retracts and moves, because the comb strips 8 are placed inside the cross-shaped arrangement of the brush plate 7, the position of the comb strips 8 remains unchanged and continues to rotate with the brush plate 7 as it moves backward. This allows the brush plate 7 to contact the surface of the comb strips 8, combing the dirt adsorbed on the surface of the brush plate 7 and pushing out the dirt inside the brush plate 7. Furthermore, the brush plate 7 moves backward once every half rotation, which also avoids the brush plate 7 continuously brushing against the surface of the spray mechanism 3, causing the cleaned dirt to continuously rub against the spray mechanism 3, thereby deepening the blockage of the spray mechanism 3 itself. At the same time, the shell The water curtain nozzle 19 installed on the top of the inner wall of the body 5 continuously sprays water to rinse the brush plate 7 and the spray mechanism 3 at the bottom, and removes the dirt directly from the surface of the spray mechanism 3, avoiding dirt residue and accumulation inside the device, and further improving cleaning efficiency and effect. The top of the water curtain nozzle 19 is equipped with a water supply device, which can supply water to the water curtain nozzle 19, and the top of the shaft rotating plate 14 is equipped with a water supply pipe, which is connected to the shaft rotating plate 14. The shaft rotating plate 14 is installed on the side of the spray mechanism 3 so that the spray mechanism 3 can be supplied with water through the water pipe.

[0059] Furthermore, refer to Figure 1As shown in this embodiment: the upper half of the surrounding groove 33 is a V-shaped structure that is opened around the surface of the hollow column 27, and the lower half is a semi-circular structure that is opened around the surface of the hollow column 27. The two ends of the V-shaped structure are connected to the semi-circular structure. The protruding column 32 slides along the surrounding groove 33. By utilizing the V-shaped structure of the surrounding groove 33, when the surrounding groove 33 slides along this trajectory, it can drive the hollow column 27 to move repeatedly for a certain distance. When the protruding column 32 slides into the semi-circular section of the surrounding groove 33, the hollow column 27 will be in a state of being in contact with the spray mechanism 3 and rotate. Thus, the hollow column 27 follows the hollow sliding column 26 to achieve extension and retraction and contact movement.
