[0011] A purification method for an artificial wetland sewage purification device, the purification method for an artificial wetland sewage purification device comprising the following specific steps:

[0012] S1. Connect the sewage pipe to the top of the tee pipe through a flange. The sewage enters the machine body through the tee pipe and is filtered through the filter plate. Disinfection reagent is added to the machine body through the feeding pipe, and the motor is started to control the rotation of the stirring roller so that the disinfection reagent and the filtered water are repeatedly mixed to complete the sewage purification. Then the treated water is discharged through the discharge pipe;

[0013] S2. When one side of the filter plate is clogged after long-term use, sewage can no longer pass through the filter plate on one side. As it continues to accumulate, the filter plate on one side moves downward under the action of gravity, and the filter plate on one side contacts the U-shaped rod, pushing the U-shaped rod to move downward together. The U-shaped rod slides downward along the arc groove on the surface of the cylinder, causing the cylinder to rotate, and the through hole on one side of the cylinder rotates until it no longer overlaps with the through hole on one side of the baffle. At this time, the three-way pipe that is blocking the filter plate on this side is blocked, and the cylinder on one side pulls the cross bar to move through the rotating rod, causing the cylinder on the other side to rotate, and the through hole of the cylinder on the other side rotates to overlap with the through hole of the baffle on the other side. The three-way pipe on the other side is opened, and the sewage is filtered through the three-way pipe on the other side and the filter plate;

[0014] S3. When the crossbar moves to the right, it contacts the contact plate and pushes the connecting rod to rotate a certain angle. The connecting rod drives the pointer to rotate, and when the filter plate moves downward, the filter plate moves downward with the drum. At this time, the L-shaped rod slides upward in the spiral groove on the inner side of the drum, causing the drum to rotate. The drum pulls the scraper to move to the side close to the 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 on the top can be filtered through the filter plate and flow through the filter plate first;

[0015] S4. When the filter plate is blocked and moves downward, the filter plate can contact the cross plate to push the limit rod downward, and the limit rod can withdraw from the limit hole to release the limit on the cam. In the process of the limit rod moving downward, the limit rod moves downward with the card knife, and the card knife contacts the card block, and the card knife is pushed to the right. When the card knife moves to the bottom of the card block, the card knife can pop out and contact the bottom of the card block under the action of spring four to limit the limit rod. When the staff turns the knob to control the rotation of the cam, the cam no longer limits the card rod, and the card rod can move to the side close to the center of the plug-in rack under the action of spring two, and the card rod can withdraw from the card hole to release the limit on the plug-in rack. When the cam contacts When it is on the inclined surface at the top of the limit rod, the limit rod is pushed downward again for a certain distance, and the limit rod moves downward with the card knife, and the card knife is resisted by the slider and moves to the right. When the card knife moves to the bottom of the slider, the card knife pops out and resists the bottom of the slider under the action of spring four. At this time, under the action of spring three, the limit rod moves upward, and the limit rod moves upward with the card knife, and the card knife resists the slider and moves upward with the slider. When the slider is embedded in the card block, the slider and the card block cannot move, and the card knife can be resisted to move to the right, so that the card knife is separated from the slider and the card block, thereby releasing the limit on the limit rod. At this time, you only need to take out the socket frame, clean the clogged filter plate, and then reinsert the socket frame.

[0017] 1. The artificial wetland sewage purification device and purification method, through the set filtering assembly, with long-term use, when one side of the filter plate is blocked due to excessive impurities filtered, the sewage can no longer pass through. With continuous accumulation, the filter plate on one side moves downward under the action of gravity, and can abut on the U-shaped rod to drive the U-shaped rod to move downward, so that the cylinder rotates, and the through hole on one side of the cylinder rotates until it no longer coincides with the through hole on one side of the baffle plate, thereby blocking the three-way pipe on this side, and opening the three-way pipe on the other side, so that the filtering operation can be carried out. The staff only needs to pull out the plug-in frame on the blocked side and clean the filter plate. The filter plate can be replaced and cleaned without stopping work, which effectively improves the work efficiency.

[0018] 2. The artificial wetland sewage purification device and purification method, through the filter assembly and indicator assembly, when the filter plate is switched, the cross bar can abut on 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 cross bar no longer abuts against the contact plate, the connecting rod and the contact plate can be rotated in the opposite direction by a certain angle under the action of the spring sheet, so that the pointer is restored, which can effectively prevent the staff from disassembling the wrong corresponding filter plate when disassembling and cleaning the filter plate, thereby causing sewage to flow out.

The artificial wetland sewage purification device and purification method, through the provided filtering assembly and driven assembly, when the filter plate moves downward, the filter plate moves downward with the drum, at this time the L-shaped rod slides upward in the spiral groove on the inner side of the drum, causing the drum to rotate, and the drum pulls the scraper to move to the side close to the drum through the winding rope, and the scraper can scrape off the impurities on the top of the filter plate, so that when the filter plate is blocked, the sewage on the top can be filtered by the filter plate and flow away through the filter plate first, which can effectively prevent the sewage from flowing out when the staff pulls out the plug-in frame.

[0020] 4. The artificial wetland sewage purification device and purification method, through the provided filtering assembly and locking assembly, can release the limit on the cam only when the filter plate is blocked and moves downward, at this time, the knob can be turned to control the card rod to release the limit on the plug-in frame and take out the plug-in frame, thereby ensuring the stability of the plug-in frame during use, and at the same time, it can prevent the staff from accidentally touching the knob, causing the plug-in frame to loosen and be pulled out, causing sewage to flow out. Only when the filter plate is blocked and moves downward, can the limit on the knob be released, at this time, the knob can be turned to control the card rod to release the limit on the plug-in frame.

[0041] S2. When the filter plate 22 on one side is clogged after long-term use, the sewage can no longer pass through the filter plate 22 on one side. As it accumulates continuously, the filter plate 22 on one side moves downward under the action of gravity, and the filter plate 22 on one side contacts the U-shaped rod 27, pushing the U-shaped rod 27 to move downward together. The U-shaped rod 27 slides downward along the arc groove 26 on the surface of the cylinder 25, so that the cylinder 25 rotates, and the through hole on the cylinder 25 on one side rotates until it no longer coincides with the through hole on the baffle plate 24 on one side. At this time, the three-way pipe 7 that is blocking the filter plate 22 on this side is blocked, and the cylinder 25 on one side pulls the cross bar 29 to move through the rotating rod 28, so that the cylinder 25 on the other side rotates, and the through hole of the cylinder 25 on the other side rotates to coincide with the through hole of the baffle plate 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;

[0042] S3. When the cross bar 29 moves to the right, the cross bar 29 contacts the contact plate 33 and pushes the connecting rod 31 to rotate 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 with the drum 41. At this time, the L-shaped rod 46 slides upward in the spiral groove 45 on the inner side of the drum 41, so that the drum 41 rotates. The drum 41 pulls the scraper 43 to move to the side close to the drum 41 through the winding rope 42. The scraper 43 can scrape the impurities on the top of the filter plate 22, so that when the filter plate 22 is blocked, the sewage on the top can be filtered by the filter plate 22 and flow through the filter plate 22 first.

[0043] When the filter plate 22 is blocked and moves downward, the filter plate 22 can contact the cross plate 510 to push the limit rod 56 downward, and the limit rod 56 can withdraw from the limit hole 515 to release the limit of the cam 52. In the process of the limit rod 56 moving downward, the limit rod 56 moves downward with the card knife 57, and the card knife 57 contacts the card block 512, and the card knife 57 is pushed to move to the right. When the card knife 57 moves to the bottom of the card block 512, the card knife 57 can pop out under the action of the spring four 59 and contact the bottom of the card block 512 to limit the limit rod 56. When the staff turns the knob 51 to control the rotation of the cam 52, the cam 52 no longer limits the card rod 53, and the card rod 53 can move to one side close to the center of the plug-in frame 21 under the action of the spring two 54, and the card rod 53 can withdraw from the card hole 514 to release the limit of the plug-in frame 21. When the slider 513 is embedded in the card block 512, the slider 513 and the card block 512 cannot move and can resist the card knife 57 to move rightward, so that the card knife 57 is separated from the slider 513 and the card block 512, thereby releasing the limit of the limit rod 56. At this time, you only need to take out the plug-in rack 21, clean the clogged filter plate 22, and then reinsert the plug-in rack 21.

[0044] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.

When the filter plate (22) on one side is clogged after long-term use, the sewage can no longer pass through the filter plate (22) on one side. As the sewage accumulates, the filter plate (22) on one side moves downward under the action of gravity. The filter plate (22) on one side abuts against the U-shaped rod (27), pushing the U-shaped rod (27) to move downward together. The U-shaped rod (27) slides downward along the arc groove (26) on the surface of the cylinder (25), causing the cylinder (25) to rotate. The filter plate (22) on one side of the cylinder (25) is blocked. The hole rotates until it no longer overlaps with the through hole on the baffle plate (24) on one side. At this time, the three-way pipe (7) that blocks the filter plate (22) on this side is blocked, and the cylinder (25) on one side pulls the cross bar (29) to move through the rotating rod (28), so that the cylinder (25) on the other side rotates, and the through hole of the cylinder (25) on the other side rotates to overlap with the through hole of the baffle plate (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 cross bar (29) moves to the right, the cross bar (29) contacts the contact plate (33) to push the connecting rod (31) to rotate a certain angle, and the connecting rod (31) drives the pointer (32) to rotate, and when the filter plate (22) moves downward, the filter plate (22) moves downward with the rotating drum (41), and at this time, the L-shaped rod (46) slides upward in the spiral groove (45) on the inner side of the rotating drum (41), so that the rotating drum (41) rotates, and the rotating drum (41) pulls the scraper (43) to move to the side close to the rotating drum (41) through the winding rope (42), and 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 on the top can be filtered by the filter plate (22) and flow through the filter plate (22) first; S4. When the filter plate (22) is blocked and moves downward, the filter plate (22) can abut against the horizontal plate (510) to push the limit rod (56) downward, and the limit rod (56) can withdraw from the limit hole (515) to release the limit on the cam (52). In the process of the limit rod (56) moving downward, the limit rod (56) moves downward with the clamping knife (57), and the clamping knife (57) abuts against the clamping block (512). The clamping knife (57) is pushed to move to the right. When the clamping knife (57) moves to the bottom of the clamping block (512), After the clamping knife (57) is moved, the clamping knife (57) can pop out under the action of the spring four (59) to abut against the bottom of the clamping block (512) to limit the limit rod (56). When the staff rotates the knob (51) to control the cam (52) to rotate, the cam (52) no longer limits the clamping rod (53). The clamping rod (53) can move to a side close to the center of the plug-in frame (21) under the action of the spring two (54). The clamping rod (53) can withdraw from the clamping hole (514) to release the limit on the plug-in frame (21). When the cam (52) abuts against the limit When the positioning rod (56) is on the inclined surface at the top, the limiting rod (56) is pushed to move downward a certain distance again, and the limiting rod (56) moves downward with the card knife (57), and the card knife (57) is resisted by the slider (513) and moves to the right. When the card knife (57) moves to the bottom of the slider (513), the card knife (57) pops out and resists the bottom of the slider (513) under the action of the spring four (59). At this time, under the action of the spring three (58), the limiting rod (56) moves upward, and the limiting rod (56) and the card knife (57) move upward together. The knife (57) moves upward, and the slider (513) contacts the slider (513) and moves upward with the slider (513). When the slider (513) is embedded in the block (512), the slider (513) and the block (512) cannot move, and the knife (57) moves rightward, so that the knife (57) is separated from the slider (513) and the block (512), thereby releasing the limit of the limit rod (56). At this time, it is only necessary to take out the plug-in frame (21), clean the blocked filter plate (22), and then reinsert the plug-in frame (21).
