Technical Field
[0001] This invention relates to the field of wastewater purification and treatment technology, specifically to an artificial wetland wastewater purification device and method. Background Technology
[0002] Constructed wetlands are artificially created and controlled wetland-like landforms. They represent a water pollution treatment method that more closely approximates natural purification. Before wastewater is discharged into a constructed wetland, filtration and purification devices are used to filter out large-volume impurities.
[0003] For example, the artificial wetland wastewater purification device disclosed in announcement number CN220376502U has a problem that after long-term use, too many impurities adhere to the filter plate, which can easily cause blockage and affect the normal passage of wastewater. This requires staff to remove the filter plate for cleaning and replacement, but this requires stopping the purification work and affecting the overall efficiency. Therefore, we propose an artificial wetland wastewater purification device and purification method. Summary of the Invention
[0004] The purpose of this invention is to provide an artificial wetland wastewater purification device and method to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an artificial wetland wastewater purification device, comprising a body and a stirring device disposed inside and on the right side of the body, a three-way pipe connected and fixed to the top of the body, a discharge pipe disposed at the bottom of the body, a partition plate fixed to the inner wall of the body, a feeding pipe disposed on the left side of the body, a filter assembly for filtering wastewater and capable of switching filters disposed on the surface and inside of the body, an indicator assembly for prompting workers disposed on the inside and surface of the body, and a driven assembly for cleaning and a locking assembly for limiting position disposed on the filter assembly.
[0006] Preferably, the filter assembly includes a connector that penetrates the surface of the machine body and is inserted into the machine body. A filter plate is slidably mounted on the inner side of the connector. A spring is fixed to the bottom of the filter plate, and the end of the spring away from the filter plate is fixed to the inner side of the connector. A baffle is fixed to the bottom of the three-way pipe. A cylinder is rotatably mounted on the surface of the three-way pipe. An arc-shaped groove is formed on the surface of the cylinder. A U-shaped rod is inserted into the inner side of the arc-shaped groove and slidably mounted on the machine body. On the inner wall of the body, the end of the U-shaped rod away from the cylinder passes through the insertion frame. Two sets of the insertion frame, filter plate, spring, baffle, cylinder, arc groove, and U-shaped rod are provided, and both sets are symmetrically arranged about the center line of the machine body. Rotating rods are rotatably mounted at the bottom of both sets of cylinders, and crossbars are fixed at the bottom of both sets of rotating rods. Through holes are provided on both the cylinder and the baffle, and the crossbar passes through the partition. When the through holes on the cylinder and the baffle plate coincide, wastewater can enter the machine through the T-connector and the cylinder for treatment. With prolonged use, if one side of the filter plate becomes clogged due to excessive impurities, wastewater can no longer pass through. As impurities accumulate, the filter plate on one side moves downwards under gravity. This causes the U-shaped rod to move downwards, sliding down along the arc groove on the cylinder surface, causing the cylinder to rotate. The through hole on one side of the cylinder rotates until it no longer coincides with the through hole on the baffle plate, thus blocking the T-connector on that side. Simultaneously, the cylinder on one side pulls the crossbar via a rotating rod, causing the other cylinder to rotate until its through hole coincides with the baffle plate on the other side, opening the T-connector on that side and allowing filtration. Operators only need to remove the plug-in bracket on the clogged side to clean the filter plate; filter plate replacement and cleaning can be performed without stopping operation, effectively improving work efficiency.
[0007] Preferably, the indicating component includes a connecting rod that passes through the machine body and the partition plate, and is rotatably connected to the machine body. A pointer is fixed to the surface of the connecting rod, and an abutment plate is fixed to the bottom of the connecting rod. A spring is fixed to the right side of the abutment plate, and the end of the spring away from the abutment plate is fixed to the partition plate. When the crossbar moves to the right, the crossbar can abut against the abutment plate, pushing the connecting rod to rotate the pointer by a certain angle. When the pointer points to a certain side, it means that the filter plate on the corresponding side can be cleaned. When the crossbar no longer abuts against the abutment plate, the connecting rod and the abutment plate can rotate in the opposite direction by a certain angle under the action of the spring, so that the pointer returns to its original position. This can effectively prevent workers from disassembling and cleaning the filter plates by removing the wrong filter plates, which would cause sewage to flow out.
[0008] Preferably, the driven component includes a rotating drum, which is rotatably mounted on top of the filter plate. A pull rope is wound and fixed to the surface of the rotating drum. A scraper is fixed to the end of the pull rope away from the rotating drum. The scraper is slidably mounted on the inner side of the connector frame. A rubber rope is fixed to the side of the scraper away from the pull rope. The end of the rubber rope away from the scraper is fixed to the inner side of the connector frame. A spiral groove is formed on the inner side of the rotating drum. An L-shaped rod is inserted into the inner side of the spiral groove. The L-shaped rod passes through the filter plate. The bottom of the L-shaped rod is fixed to the inner side of the connector frame. When the filter plate moves downward, the filter plate moves downward along with the rotating drum. At this time, the L-shaped rod slides upward in the spiral groove on the inner side of the rotating drum, causing the rotating drum to rotate. The rotating drum pulls the scraper to the side closer to the rotating drum by winding the pull rope. The scraper can then scrape off the impurities on the top of the filter plate. This allows the sewage at the top of the filter plate to pass through the filter plate before flowing away when the filter plate is clogged, effectively preventing sewage from flowing out when the connector frame is pulled out by the operator.
[0009] Preferably, the locking assembly includes a knob that passes through and is rotatably connected to the connector frame. The knob is fixed to the surface of a cam, which is rotatably mounted on the inner wall of the connector frame. The connector frame is penetrated by a locking rod and slidably connected to it. A second spring is fixed to the inner wall of the connector frame, with one end of the second spring away from the connector frame fixed to the locking rod. A fixing rod is fixed to the inner wall of the connector frame, passing through and slidably connected to a limiting rod. A third spring is fixed to the bottom of the limiting rod, with one end of the third spring away from the limiting rod fixed to the inner wall of the connector frame. A locking blade passes through and slidably connects the left side of the limiting rod. A locking device is fixed to the left side of the limiting rod. Spring four, with one end of the spring away from the limiting rod fixed to the chuck, a horizontal plate fixed to the side of the limiting rod near the filter plate, a vertical rod fixed to the inner wall of the insertion bracket, a locking block fixed to the top of the vertical rod, the vertical rod passing through the slider and slidably connected to the slider, a locking hole opened on the inner wall of the machine body, a limiting hole opened at the bottom of the cam, the locking rod can be inserted into the locking hole on the inner wall of the machine body to limit the insertion bracket, the limiting rod can be inserted into the limiting hole at the bottom of the cam to limit the cam, when the filter plate is blocked and moves downward, the filter plate can abut against the horizontal plate to push the limiting rod downward, the limiting rod can then retract from the limiting hole to release the limiting of the cam, the limiting rod moves downward During the process, the limit rod moves downwards along with the chuck, and the chuck abuts against the chuck block. The chuck is pushed to the right. When the chuck moves to the bottom of the chuck block, it can be ejected by spring four and abut against the bottom of the chuck block to limit the limit rod. When the operator turns the knob to control the cam to rotate, the cam no longer limits the chuck, and the chuck can move towards the center of the connector under the action of spring two. The chuck can then exit from the chuck hole, releasing the limit on the connector. When the cam abuts against the inclined surface at the top of the limit rod, it pushes the limit rod downwards again by a certain distance. The limit rod moves downwards along with the chuck, and the chuck is abutted to the right by the slider. When the chuck moves to the bottom of the slider... After the first part is in place, the chuck pops out under the action of spring four and abuts against the bottom of the slider. At this time, under the action of spring three, the limit rod moves upward, and the limit rod moves upward along with the chuck. The chuck abuts against the slider and moves upward along with the slider. When the slider is embedded in the locking block, the slider and the locking block cannot move, and the chuck moves to the right, so that the chuck separates from the slider and the locking block, thereby releasing the limit on the limit rod. This ensures the stability of the plug-in frame during use and also prevents the operator from accidentally touching the knob, causing the plug-in frame to loosen and be pulled out, resulting in sewage flowing out. Only when the filter plate is blocked and moves downward can the limit on the knob be released. Only then can the knob be turned to control the chuck to release the limit on the plug-in frame.
[0010] Preferably, the stirring device consists of a motor and a stirring roller. The motor is fixed on the right side of the machine body, and the output shaft of the motor passes through the machine body and is rotatably connected to the machine body. The output shaft of the motor is fixed to the stirring roller. By driving the stirring roller to rotate through the motor, the water inside the machine body can be stirred. When pouring the disinfectant, it can be ensured that the disinfectant and the water inside the machine body are fully mixed.
[0011] A purification method for a constructed wetland wastewater purification device includes the following specific steps:
[0012] S1. Connect the top of the sewage pipe and the tee pipe with a flange. Sewage enters the machine body through the tee pipe and is filtered by the filter plate. Disinfectant is added into the machine body through the feeding pipe. Start the motor and control the rotation of the stirring roller so that the disinfectant is repeatedly mixed with the filtered water to complete the sewage purification. The treated water is then discharged through the discharge pipe.
[0013] S2. When one side of the filter plate becomes clogged after prolonged use, sewage can no longer pass through that side of the filter plate. As the sewage accumulates, the filter plate on one side moves downward under the influence of gravity. The filter plate on one side comes into contact with the U-shaped rod, pushing the U-shaped rod downward together. The U-shaped rod slides down along the arc groove on the surface of the cylinder, causing the cylinder to rotate. The through hole on one side of the cylinder rotates until it no longer coincides with the through hole on the baffle on one side. At this time, the T-connector on the clogged filter plate is blocked. One side of the cylinder moves by pulling the crossbar through the rotating rod, causing the other side of the cylinder to rotate. The through hole on the other side of the cylinder rotates until it coincides with the through hole on the baffle on the other side. The T-connector on the other side is opened, and the sewage passes through the T-connector on the other side and the filter plate for filtration.
[0014] S3. When the crossbar moves to the right, it abuts against the contact plate and pushes the connecting rod to rotate at a certain angle. The connecting rod drives the pointer to rotate. When the filter plate moves downward, the filter plate moves downward along with the rotating drum. At this time, the L-shaped rod slides upward in the spiral groove inside the rotating drum, causing the rotating drum to rotate. The rotating drum pulls the scraper to move towards the side closer to the rotating drum through the winding rope. The scraper can scrape off the impurities on the top of the filter plate, so that when the filter plate is blocked, the sewage at the top can be filtered through the filter plate and flow away.
[0015] S4. When the filter plate is blocked and moves downwards, it can abut against the horizontal plate, pushing the limit rod downwards. The limit rod can then exit from the limit hole, releasing the cam's restriction. During the downward movement of the limit rod, the limit rod moves downwards along with the chuck. The chuck abuts against the chuck block and is pushed to the right. When the chuck moves to the bottom of the chuck block, it can be ejected by spring four and abut against the bottom of the chuck block, limiting the limit rod. When the operator rotates the knob to control the cam to rotate, the cam no longer limits the chuck. The chuck can then move towards the center of the connector under the action of spring two, and the chuck can exit from the chuck hole, releasing the restriction on the connector. When the cam abuts against... When the limit rod is on the inclined surface at the top, push the limit rod downwards a certain distance again. The limit rod moves downwards along with the chuck. The chuck is pushed to the right by the slider. When the chuck moves to the bottom of the slider, it pops out under the action of spring four and pushes against the bottom of the slider. At this time, under the action of spring three, the limit rod moves upwards, and the limit rod moves upwards along with the chuck. The chuck pushes against the slider and moves upwards along with the slider. When the slider is embedded in the chuck block, the slider and the chuck block cannot move and push against the chuck block to the right, so that the chuck block separates from the slider and the chuck block, thereby releasing the limit on the limit rod. At this time, you only need to take out the plug-in bracket, clean the clogged filter plate, and then put the plug-in bracket back in.
[0016] Compared with the prior art, the present invention provides an artificial wetland wastewater purification device and method, which has the following beneficial effects:
[0017] 1. This constructed wetland wastewater purification device and method, through its filter components, addresses the issue of excessive impurities accumulating on one side of the filter plate over time, causing blockage and preventing wastewater from passing through. As impurities accumulate, the filter plate on that side moves downwards under gravity, contacting a U-shaped rod and causing it to rotate. This rotation prevents the through-hole on one side of the cylinder from aligning with the through-hole on the baffle plate, thus blocking the T-junction on that side while opening the T-junction on the other side, allowing for filtration. Operators only need to remove the plug-in bracket on the blocked side to clean the filter plate, enabling filter plate replacement and cleaning without stopping operation, effectively improving work efficiency.
[0018] 2. This constructed wetland wastewater purification device and method, through the set filter components and indicator components, when the filter plates are switched, the crossbar can abut against the contact plate, pushing the connecting rod to drive the pointer to rotate a certain angle. When the pointer points to a certain side, it means that the filter plate on the corresponding side can be cleaned. When the crossbar no longer abuts against the contact plate, the connecting rod and the contact plate can rotate in the opposite direction a certain angle under the action of the spring, so that the pointer returns to normal. This can effectively prevent the staff from disassembling and cleaning the filter plates and accidentally disassembling the wrong filter plate, which would cause wastewater to flow out.
[0019] 3. The constructed wetland wastewater purification device and method, through the set filter components and driven components, when the filter plate moves downward, the filter plate moves downward along with the rotating cylinder. At this time, the L-shaped rod slides upward in the spiral groove inside the rotating cylinder, causing the rotating cylinder to rotate. The rotating cylinder pulls the scraper to move to the side closer to the rotating cylinder through the winding rope. The scraper can scrape off the impurities on the top of the filter plate, so that when the filter plate is blocked, the wastewater at the top can be filtered through the filter plate and flow away first. This can effectively prevent wastewater from flowing out when the staff pulls out the plug-in frame.
[0020] 4. The constructed wetland wastewater purification device and method, through the setting of filter components and locking components, can only release the cam limit after the filter plate is blocked and moves downward. Only then can the knob be turned to control the lever to release the limit on the plug-in frame and remove the plug-in frame. This ensures the stability of the plug-in frame during use and can also prevent the operator from accidentally touching the knob, causing the plug-in frame to loosen and be pulled out, resulting in wastewater leakage. Only when the filter plate is blocked and moves downward can the knob limit be released. Only then can the knob be turned to control the lever to release the limit on the plug-in frame.

[0033] like Figures 1-11 As shown, the present invention provides a technical solution: an artificial wetland wastewater purification device, including a body 1 and a stirring device 6 disposed inside and on the right side of the body 1. A three-way pipe 7 is connected to and fixed to the top of the body 1, a discharge pipe 8 is disposed at the bottom of the body 1, a partition plate 10 is fixed to the inner wall of the body 1, a feeding pipe 9 is disposed on the left side of the body 1, a filter assembly 2 for filtering wastewater and capable of switching filters is disposed on the surface and inside of the body 1, an indicator assembly 3 for prompting workers is disposed on the inside and surface of the body 1, and a driven assembly 4 for cleaning and a locking assembly 5 for limiting position are disposed on the filter assembly 2.
[0034] The filter assembly 2 includes a connector 21 that penetrates the surface of the body 1 and is inserted into it. A filter plate 22 is slidably mounted on the inner side of the connector 21. A spring 23 is fixed to the bottom of the filter plate 22, and the end of the spring 23 away from the filter plate 22 is fixed to the inner side of the connector 21. A baffle 24 is fixed to the bottom of the three-way pipe 7. A cylinder 25 is rotatably mounted on the surface of the three-way pipe 7. An arc-shaped groove 26 is formed on the surface of the cylinder 25. A U-shaped rod 27 is inserted into the inner side of the arc-shaped groove 26. The U-shaped rod 27 is slidably mounted on the inner wall of the body 1. One end of the cylinder 25 passes through the insertion frame 21. Two sets of the insertion frame 21, filter plate 22, spring 23, baffle 24, cylinder 25, arc groove 26, and U-shaped rod 27 are provided. Both sets of the insertion frame 21, filter plate 22, spring 23, baffle 24, cylinder 25, arc groove 26, and U-shaped rod 27 are symmetrically arranged about the center line of the machine body 1. Rotating rods 28 are rotatably mounted at the bottom of both sets of cylinders 25. A crossbar 29 is fixed at the bottom of both sets of rotating rods 28. Through holes are provided on both the cylinder 25 and the baffle 24. The crossbar 29 passes through the partition plate 1. 0. When the through holes on the cylinder 25 and the baffle 24 coincide, sewage can enter the interior of the machine body 1 through the three-way pipe 7 and the cylinder 25 for treatment. With prolonged use, if the impurities filtered by one side of the filter plate 22 become too numerous and clogged, sewage can no longer pass through. As impurities accumulate, the filter plate 22 moves downwards under gravity. The filter plate 22 can then abut against the U-shaped rod 27, causing the U-shaped rod 27 to move downwards. The U-shaped rod 27 slides down along the arc-shaped groove 26 on the surface of the cylinder 25, causing the cylinder 25 to rotate. The through holes on one side of the cylinder 25... The cylinder 25 is rotated until it no longer coincides with the through hole on one side baffle 24, thus blocking the three-way pipe 7 on that side. At the same time, one side cylinder 25 pulls the crossbar 29 through the rotating rod 28, causing the other side cylinder 25 to rotate. The other side cylinder 25 rotates until its through hole coincides with the other side baffle 24, thus opening the three-way pipe 7 on the other side, allowing for filtration. The operator only needs to pull out the plug bracket 21 blocking this side to clean the filter plate 22. The filter plate 22 can be replaced and cleaned without stopping the work, effectively improving work efficiency.
[0035] The indicator component 3 includes a connecting rod 31, which passes through the body 1 and the partition plate 10 and is rotatably connected to the body 1. A pointer 32 is fixed on the surface of the connecting rod 31, and an abutment plate 33 is fixed at the bottom of the connecting rod 31. A spring piece 34 is fixed on the right side of the abutment plate 33, and the end of the spring piece 34 away from the abutment plate 33 is fixed to the partition plate 10. When the crossbar 29 moves to the right, the crossbar 29 can abut against the abutment plate 33, pushing the connecting rod 31 to rotate the pointer 32 by a certain angle. When the pointer 32 points to a certain side, it means that the filter plate 22 on the corresponding side can be cleaned. When the crossbar 29 no longer abuts against the abutment plate 33, the connecting rod 31 and the abutment plate 33 can rotate in the opposite direction by a certain angle under the action of the spring piece 34, so that the pointer 32 returns to its original position. This can effectively prevent the operator from disassembling the wrong filter plate 22 when disassembling and cleaning the filter plate 22, which would cause sewage to flow out.
[0036] Driven component 4 includes a rotating drum 41, which is rotatably mounted on top of filter plate 22. A pull rope 42 is wound and fixed on the surface of the rotating drum 41. A scraper 43 is fixed to the end of the pull rope 42 away from the rotating drum 41. The scraper 43 is slidably mounted on the inner side of the insertion frame 21. A rubber rope 44 is fixed to the side of the scraper 43 away from the pull rope 42. The end of the rubber rope 44 away from the scraper 43 is fixed to the inner side of the insertion frame 21. A spiral groove 45 is formed on the inner side of the rotating drum 41. An L-shaped rod 46 is inserted into the inner side of the spiral groove 45. The L-shaped rod 46 passes through the filter plate 22, and the bottom of the L-shaped rod 46 is fixed to... Inside the plug-in bracket 21, when the filter plate 22 moves downward, the filter plate 22 moves downward along with the rotating drum 41. At this time, the L-shaped rod 46 slides upward in the spiral groove 45 inside the rotating drum 41, causing the rotating drum 41 to rotate. The rotating drum 41 pulls the scraper 43 to move closer to the rotating drum 41 through the winding rope 42. The scraper 43 can scrape off the impurities on the top of the filter plate 22, so that when the filter plate 22 is blocked, the sewage at the top can be filtered through the filter plate 22 and flow away first. This can effectively prevent sewage from flowing out when the plug-in bracket 21 is pulled out by the staff.
[0037] The locking assembly 5 includes a knob 51, which passes through and is rotatably connected to the connector 21. The knob 51 is fixed to the surface of a cam 52, which is rotatably mounted on the inner wall of the connector 21. The connector 21 is penetrated by a locking rod 53 and is slidably connected to the locking rod 53. A second spring 54 is fixed to the inner wall of the connector 21, with one end of the second spring 54 away from the connector 21 fixed to the locking rod 53. A fixing rod 55 is fixed to the inner wall of the connector 21, which passes through and is slidably connected to a limiting rod 56. A third spring 58 is fixed to the bottom of the limiting rod 56, with one end of the third spring 58 away from the limiting rod 56 fixed to the inner wall of the connector 21. A locking blade 57 passes through and is slidably connected to the left side of the limiting rod 56. A spring 59 is fixed to the left side of the limiting rod 56. The end of the spring 59 away from the limiting rod 56 is fixed to the clamping knife 57. A horizontal plate 510 is fixed to the side of the limiting rod 56 near the filter plate 22. A vertical rod 511 is fixed to the inner wall of the insertion bracket 21. A clamping block 512 is fixed to the top of the vertical rod 511. The vertical rod 511 passes through the slider 513 and is slidably connected to the slider 513. A clamping hole 514 is opened on the inner wall of the machine body 1. A limiting hole 515 is opened at the bottom of the cam 52. The clamping rod 53 can be inserted into the clamping hole 514 on the inner wall of the machine body 1 to limit the insertion bracket 21. The limiting rod 56 can be inserted into the limiting hole 515 at the bottom of the cam 52 to limit the cam 52. When the filter plate 22 is blocked and moves downward, the filter plate 22 can resist... When the limit rod 56 is pushed downwards by the contact with the horizontal plate 510, it can retract from the limit hole 515, releasing the limit on the cam 52. During the downward movement of the limit rod 56, the limit rod 56 moves downwards along with the chuck 57. The chuck 57 abuts against the chuck block 512 and is pushed to the right. When the chuck 57 moves to the bottom of the chuck block 512, it can be ejected by the action of the fourth spring 59 and abut against the bottom of the chuck block 512, limiting the limit rod 56. When the operator turns the knob 51 to control the rotation of the cam 52, the cam 52 no longer limits the chuck 53. The chuck 53 can then move towards the side closer to the center of the connector 21 by the action of the second spring 54, and the chuck 53 can then exit from the chuck hole 514. The internal movement releases the limiting mechanism on the connector 21. When the cam 52 abuts against the inclined surface at the top of the limiting rod 56, it pushes the limiting rod 56 downward a certain distance. The limiting rod 56 moves downward along with the chuck 57. The chuck 57 is pushed to the right by the slider 513. When the chuck 57 reaches the bottom of the slider 513, it pops out under the action of spring 4 59 and abuts against the bottom of the slider 513. At this time, under the action of spring 3 58, the limiting rod 56 moves upward, and the limiting rod 56 moves upward along with the chuck 57. The chuck 57 abuts against the slider 513 and moves upward along with the slider 513. When the slider 513 is embedded in the locking block 512, the slider 513 and the locking block 512 cannot move, and the chuck 57 moves to the right.This allows the clamping knife 57 to separate from the slider 513 and the clamping block 512, releasing the limit on the limiting rod 56 and ensuring the stability of the connector 21 during use. It also prevents accidental activation of the knob 51 by operators, which could cause the connector 21 to loosen and be pulled out, resulting in wastewater leakage. The limit on the knob 51 can only be released after the filter plate 22 has become clogged and moved downwards. Only then can the knob 51 be rotated to control the clamping rod 53 to release the limit on the connector 21.
[0038] The mixing device 6 consists of a motor 61 and a mixing roller 62. The motor 61 is fixed on the right side of the machine body 1. The output shaft of the motor 61 passes through the machine body 1 and is rotatably connected to the machine body 1. The output shaft of the motor 61 is fixed to the mixing roller 62. By driving the mixing roller 62 to rotate through the motor 61, the water inside the machine body 1 can be stirred. When pouring the disinfectant, it can ensure that the disinfectant and the water inside the machine body 1 are fully mixed.
[0039] A purification method for a constructed wetland wastewater purification device includes the following specific steps:
[0040] S1. Connect the top of the sewage pipe to the tee pipe 7 through a flange. Sewage enters the machine body 1 through the tee pipe 7 and is filtered by the filter plate 22. Disinfectant is added to the machine body 1 through the feeding pipe 9. Start the motor 61 and control the stirring roller 62 to rotate so that the disinfectant is repeatedly mixed with the filtered water to complete the sewage purification. The treated water is then discharged through the discharge pipe 8.
[0041] S2. When one side of the filter plate 22 becomes clogged after prolonged use, sewage can no longer pass through it. As the sewage accumulates, the filter plate 22 moves downward under gravity and comes into contact with the U-shaped rod 27, pushing the rod downward as well. The U-shaped rod 27 slides down along the arc groove 26 on the surface of the cylinder 25, causing the cylinder 25 to rotate. The through hole on one side of the cylinder 25 rotates until it no longer coincides with the through hole on the baffle 24. At this point, the three-way pipe 7 of the filter plate 22 on the clogged side is blocked. The cylinder 25 moves by pulling the crossbar 29 through the rotating rod 28, causing the other side of the cylinder 25 to rotate. The through hole of the other side of the cylinder 25 rotates until it coincides with the through hole of the baffle 24. The three-way pipe 7 on the other side is opened, and the sewage passes through the three-way pipe 7 and the filter plate 22 for filtration.
[0042] S3. When the crossbar 29 moves to the right, the crossbar 29 abuts against the contact plate 33 and pushes the connecting rod 31 to rotate at a certain angle. The connecting rod 31 drives the pointer 32 to rotate. When the filter plate 22 moves downward, the filter plate 22 moves downward along with the rotating drum 41. At this time, the L-shaped rod 46 slides upward in the spiral groove 45 inside the rotating drum 41, causing the rotating drum 41 to rotate. The rotating drum 41 pulls the scraper 43 to move to the side closer to the rotating drum 41 through the winding rope 42. The scraper 43 can scrape off the impurities on the top of the filter plate 22, so that when the filter plate 22 is blocked, the sewage at the top can be filtered through the filter plate 22 and flow away.
[0043] S4. When the filter plate 22 is blocked and moves downward, it can abut against the horizontal plate 510, pushing the limiting rod 56 downward. The limiting rod 56 can then exit from the limiting hole 515, releasing the limiting of the cam 52. During the downward movement of the limiting rod 56, the limiting rod 56 moves downward along with the chuck 57. The chuck 57 abuts against the chuck block 512 and is pushed to the right. When the chuck 57 moves to the bottom of the chuck block 512, it can pop out under the action of the fourth spring 59 and abut against the bottom of the chuck block 512, limiting the limiting rod 56. When the operator turns the knob 51 to control the cam 52 to rotate, the cam 52 no longer limits the chuck 53. The chuck 53 can then move towards the side closer to the center of the connector 21 under the action of the second spring 54. The chuck 53 can then exit from the chuck hole 514, releasing the limiting of the connector 21. When the cam 52 abuts against the limiting... When the limit rod 56 is on the inclined surface at the top, push the limit rod 56 to move downward a certain distance again. The limit rod 56 moves downward together with the chuck 57. The chuck 57 is pushed to the right by the slider 513. When the chuck 57 moves to the bottom of the slider 513, the chuck 57 pops out under the action of the fourth spring 59 and pushes against the bottom of the slider 513. At this time, under the action of the third spring 58, the limit rod 56 moves upward. The limit rod 56 moves upward together with the chuck 57. The chuck 57 pushes against the slider 513 and moves upward together with the slider 513. When the slider 513 is embedded in the locking block 512, the slider 513 and the locking block 512 cannot move and can push the chuck 57 to the right, so that the chuck 57 separates from the slider 513 and the locking block 512, thereby releasing the limit on the limit rod 56. At this time, you only need to take out the plug-in bracket 21, clean the clogged filter plate 22, and then put the plug-in bracket 21 back in.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.

6. A purification method for an artificial wetland wastewater purification device, characterized in that: The wastewater purification device for constructed wetlands as described in any one of claims 1-5 comprises the following steps: S1. Connect the top of the sewage pipe to the three-way pipe (7) through a flange. The sewage enters the machine body (1) through the three-way pipe (7) and is filtered by the filter plate (22). Disinfectant is added to the machine body (1) through the feeding pipe (9). Start the motor (61) and control the stirring roller (62) to rotate so that the disinfectant is repeatedly mixed with the filtered water to complete the sewage purification. The treated water is then discharged through the discharge pipe (8). S2. When one side of the filter plate (22) becomes clogged after prolonged use, sewage can no longer pass through it. As the sewage accumulates, the filter plate (22) moves downward under gravity. The filter plate (22) then comes into contact with the U-shaped rod (27), pushing the U-shaped rod (27) downward. The U-shaped rod (27) slides down along the arc groove (26) on the surface of the cylinder (25), causing the cylinder (25) to rotate. The sewage on one side of the cylinder (25) then flows through the filter plate (22). When the hole is rotated to no longer coincide with the through hole on one side baffle (24), the three-way pipe (7) that is blocking the filter plate (22) on this side is blocked. One side cylinder (25) moves the crossbar (29) by the rotating rod (28), causing the other side cylinder (25) to rotate. The through hole of the other side cylinder (25) rotates to coincide with the through hole of the baffle (24) on the other side. The three-way pipe (7) on the other side is opened, and the sewage is filtered through the three-way pipe (7) on the other side and the filter plate (22). S3. When the crossbar (29) moves to the right, the crossbar (29) abuts against the contact plate (33) and pushes the connecting rod (31) to rotate at a certain angle. The connecting rod (31) drives the pointer (32) to rotate. When the filter plate (22) moves downward, the filter plate (22) moves downward together with the rotating drum (41). At this time, the L-shaped rod (46) slides upward in the spiral groove (45) inside the rotating drum (41), causing the rotating drum (41) to rotate. The rotating drum (41) pulls the scraper (43) to move closer to the rotating drum (41) through the winding rope (42). The scraper (43) can scrape off the impurities on the top of the filter plate (22), so that when the filter plate (22) is blocked, the sewage at the top can be filtered through the filter plate (22) and flow away first. S4. When the filter plate (22) is blocked and moves downward, the filter plate (22) can abut against the horizontal plate (510) and push the limiting rod (56) downward. The limiting rod (56) can then exit from the limiting hole (515) to release the limiting of the cam (52). During the downward movement of the limiting rod (56), the limiting rod (56) moves downward together with the chuck (57). The chuck (57) abuts against the chuck block (512) and is pushed to the right. When the chuck (57) moves to the bottom of the chuck block (512)... After the tool is in place, the chuck (57) will pop out under the action of spring four (59) and abut against the bottom of the chuck block (512) to limit the limit rod (56). When the operator turns the knob (51) to control the cam (52) to rotate, the cam (52) will no longer limit the chuck rod (53). The chuck rod (53) will then move towards the center of the connector frame (21) under the action of spring two (54). The chuck rod (53) will then exit from the chuck hole (514) and release the limit on the connector frame (21). When the cam (52) abuts against the limit rod... When the limit rod (56) is on the inclined surface at the top, push the limit rod (56) to move downward a certain distance again. The limit rod (56) moves downward together with the chuck (57). The chuck (57) is pushed to the right by the slider (513). When the chuck (57) moves to the bottom of the slider (513), the chuck (57) pops out under the action of spring four (59) and pushes against the bottom of the slider (513). At this time, under the action of spring three (58), the limit rod (56) moves upward. The limit rod (56) moves downward together with the chuck (57) to the right. Move upwards, the chuck (57) abuts against the slider (513) and moves upwards together with the slider (513). When the slider (513) is embedded in the chuck (512), the slider (513) and the chuck (512) cannot move and can abut against the chuck (57) to move to the right, so that the chuck (57) separates from the slider (513) and the chuck (512), thereby releasing the limit rod (56). At this time, you only need to take out the plug-in bracket (21), clean the clogged filter plate (22), and then put the plug-in bracket (21) back in.
