[0018] A method for using an automatically drainable circulating water purification device, comprising the following steps:

[0019] S1. The staff inputs the sewage into the interior of the water purification tank and filters it through the filter plate in the circulating filter assembly. After a long period of use, the filter plate will be clogged by impurities in the sewage. Then, by rotating the first rotating column and rotating it 90 degrees, a new filter plate is rotated into the interior of the water purification tank.

[0020] S2. Then the staff activates the first electric push rod above the clogged filter plate and causes the unclogging burrs on the surface of the squeeze plate to be inserted into the surface of the filter plate. Then, through the setting of the automatic sewage cleaning component, the blockage on the surface of the filter plate is scraped into the inside of the sewage storage tank.

[0021] S3. After filtration is completed, some floating objects will remain on the water surface. Then, the staff will start the rotating motor to move the scooping plate vertically downwards. When one end of the scooping plate moves to the bottom of the water purification tank, it will slide along the bottom of the water purification tank and make the two scooping plates on both sides interlock and fix each other. Then, the rotating motor will move the scooping plate and scoop the floating objects in the water onto the surface. When it moves to the top, the docking column is inserted into the connecting shaft, and the third motor will move the second scraper to scrape the floating objects on the surface of the scooping plate to one side for processing.

[0022] S4. After processing is complete, reset the second scraper, then open the door on one side of the sealing box, pull the puller to one side so that the plug block is disengaged from the plug slot. Then the two retrieval plates will automatically rotate and be in a vertical state without the limit. Then open the valve to drain the water source.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. With the set circulating filtration components, when the filter plate inside the water purification tank becomes clogged, the first motor can be started to rotate the first rotating column 90 degrees, placing the filter plate on the other side inside the water purification tank. Then, the filter can be filtered again by replacing the filter screen. This greatly improves the efficiency of continuous operation of the device, eliminates the need for manual replacement of the filter screen, improves filtration efficiency, ensures continuous circulating filtration operation of the device, and enhances the practicality of the device.

[0025] 2. Through the set circulating filtration component and automatic sewage discharge and cleaning component, the clogged filter plate moves to the bottom of the L-shaped rotating plate by rotation. Then, the first electric push rod on the surface of the circulating filtration component drives the squeezing plate and the unclogging burrs on the surface to rotate synchronously, so that the squeezing plate is in close contact with the lower surface of the filter plate and inserts the unclogging burrs into the filter plate, thereby pushing the blockage from the inside of the filter plate to the outside. Then, by starting the second motor, the first scraper moves to scrape the blockage into the inside of the sludge storage tank. When the filter plate rotates, it will squeeze and drive the L-shaped rotating plate to rotate, avoiding the L-shaped rotating plate from obstructing the movement of the filter plate. This achieves self-cleaning of the filter plate surface and performs sewage discharge operation, so that the filtration system can be used repeatedly, which greatly improves the filtration efficiency of the equipment.

[0026] 3. Using the floating debris retrieval assembly, the rotating motor is activated to move the retrieval plates vertically downwards from both sides. When they contact the bottom of the pool, they move along the bottom, causing the two retrieval plates to engage with each other. Then, the rotating motor is activated in the opposite direction to move the retrieval plates up and down, thereby retrievaling floating debris from the water. When the retrieval plates reach their highest point, the connecting post inserts into the connecting shaft, activating the third motor to rotate the third lead screw. This causes the second scraper to move, scraping the floating debris on the surface of the retrieval plates to one side, making it easier for workers to clean the debris. Then, the two retrieval plates are locked in place by gravity, ensuring they are in a vertical position for the next retrieval operation.

[0027] 4. Through the set water-repelling blades, toothed chain belt, fourth motor, protective plate and floating object retrieval component, when the retrieval plate moves vertically downward from both sides and contacts the bottom of the pool, the impurities attached to the bottom of the pool are removed from the bottom of the pool by the movement of the two ends of the retrieval plate. Then, the fourth motor drives the water-repelling blades to rotate. The rotation of the water-repelling blades drives the water flow, causing the impurities to fluctuate and surge, thereby assisting the movement of the retrieval plate and simultaneously retrieval the impurities attached to the bottom, maintaining the cleanliness of the pool bottom.

[0046] Please see Figures 1 to 11The automatic sewage discharge circulating water purification device of the present invention includes a water purification tank 1, a sealed box 2 provided on the upper surface of the water purification tank 1, a circulating filter assembly 3 provided inside the water purification tank 1, an automatic sewage discharge and cleaning assembly 4 provided on the upper surface of the water purification tank 1, a floating object retrieval assembly 5 provided inside the water purification tank 1, a water inlet trough opened on one side surface of the water purification tank 1, a drain pipe fixedly installed on the other side surface of the water purification tank 1, a valve fixedly installed on the outer surface of the drain pipe, and a door rotatably connected to the other side surface of the sealed box 2 via a hinge.

[0047] The circulating filter assembly 3 includes a first motor 301 fixedly installed on one side surface of the sealed box 2. A first rotating column 302 is fixedly installed at the output end of the first motor 301. Several fixing rods are fixedly installed on the outer surface of the first rotating column 302. A filter plate 303 is fixedly installed at one end of every two fixing rods. A support member is provided on the upper surface of each filter plate 303. A second rotating column 304 is rotatably connected inside the support member. A clamping rod is fixedly installed on the outer surface of the second rotating column 304. A pressing plate 305 is fixedly installed on one side of the clamping rod. Several unblocking burrs are provided on the side surface of the pressing plate 305. The unblocking burrs are adapted to the filter plate 303. A first gear 306 is fixedly installed on both sides of the outer surface of the second rotating column 304. A gear 306 has a first toothed plate 307 meshing with its side surface. A fixing plate is fixedly installed on the side surfaces of the two first toothed plates 307. A first electric push rod 308 is fixedly installed on the surface of the filter plate 303 via a clamping plate. The first electric push rod 308 is fixedly installed on the side surface of the fixing plate. Support plates 309 are fixedly installed on both sides of the upper surface of the water purification tank 1 via support columns. An annular groove 310 is opened on the side surface of the support plate 309. A guide column 311 is fixedly installed on the side surface of the fixing rod.

A first rotating column 302 is rotatably connected to the side surface of the other support plate 309.

[0048] In this embodiment: When the filter plate 303 inside the water purification tank 1 becomes clogged and needs to be replaced, the operator starts the first motor 301 to drive the first rotating column 302 to rotate. The first rotating column 302 drives the filter plate 303 to rotate through the fixed rod, causing the first rotating column 302 to rotate 90 degrees, rotating the new filter plate 303 on the other side into the water purification tank 1, and the clogged filter plate 303 on the other side is removed from the water purification tank 1. Then, when it is necessary to clean the clogged filter plate 303, the first electric push rod 308 on the upper surface of the clogged filter plate 303 is activated. The first electric push rod 308 drives the first toothed plates on both sides through the fixed plate. The first gear 306 rotates as the first toothed plate 307 moves, which in turn drives the first gear 306 to rotate. The first gear 306 then drives the second rotating column 304 inside to rotate. The second rotating column 304, through a locking rod, drives the extrusion plate 305 and the unclogging burrs on its surface to rotate, so that the extrusion plate 305 is pressed tightly against the filter plate 303 and the unclogging burrs are inserted into the interior of the filter plate 303, thereby pushing the blockage outwards to facilitate subsequent cleaning operations. When the fixed rod rotates, it drives the guide column 311 to rotate. The guide column 311 rotates inside the annular groove 310 on the side surface of the support plate 309, so that it can rotate stably.

[0049] Please refer to this carefully. Figures 1 to 11 The automatic sewage discharge and cleaning component 4 includes a sewage storage tank 401 fixedly installed on the side surface of the sealed box 2. A sewage inlet groove is provided on one side surface of the sewage storage tank 401.

A first lead screw 403 is rotatably connected to the lower surface of the L-shaped rotating plate 402. A driven column is fixedly installed on one side surface of the first lead screw 403, and the driven column is rotatably connected to the side surface of the L-shaped rotating plate 402. A second motor 404 is fixedly installed on the upper surface of plate 402. A drive shaft is fixedly installed at the output end of the second motor 404.

[0050] In this embodiment: when the extrusion plate 305 is pressed tightly against the filter plate 303 and the unblocking burrs are inserted into the interior of the filter plate 303, the blockage is pushed outward. The blocked filter plate 303 is located on the lower surface of the L-shaped rotating plate 402. Then, the second motor 404 is started to drive the drive shaft to rotate. The drive shaft drives the driven column to rotate through the pulley. The driven column drives the first lead screw 403 at one end to rotate. The rotation of the first lead screw 403 drives the sliding block and the first scraper 405 on the lower surface to move. The moving first scraper 405 removes the blockage. The blockage on the surface of the filter plate 303 is scraped into the sludge storage tank 401 through the sludge inlet groove, thereby removing the blockage and ensuring the filtration effect of the filter plate 303. Then, during the subsequent rotation, the filter plate 303 rotates and drives the L-shaped rotating plate 402 to rotate around the hinge seat through the extrusion force. The L-shaped rotating plate 402 drives the guide rod 406 to slide inside the guide arc groove 407, ensuring that the L-shaped rotating plate 402 can rotate stably and avoiding any movement obstruction to the filter plate 303.

A second lead screw 501 is rotatably connected inside the first vertical groove. A driven block 502 is threadedly connected to the outer surface of the second lead screw 501. A retrieval plate 503 is rotatably connected to the lower surface of the driven block 502. Support columns 504 are fixedly installed on the side surfaces of the two retrieval plates 503. L-shaped guide rails 505 are fixedly installed on both sides of the inner wall of the water purification tank 1. The support columns 504 are adapted to the L-shaped guide rails 505. Rotary motors 518 are fixedly mounted on both sides of the upper surface of pool 1 via motor housings. A second lead screw 501 is fixedly held at the output end of each rotary motor 518. A rectangular groove is formed inside one of the retrieval plates 503. A return spring 506 is formed on the inner bottom wall of the rectangular groove. A plug-in block 507 is fixedly mounted on one end of the return spring 506. A plug-in groove 508 is formed on one side surface of the other retrieval plate 503. The plug-in block 507 is adapted to the plug-in groove 508. A second lead screw 501 is formed on the inner top wall of the rectangular groove. A first slot is provided, and a pulling member 509 is fixedly installed on the upper surface of the plug-in block 507. The pulling member 509 is slidably connected to the inside of the first slot. A third motor 510 is fixedly installed on one side surface of the water purification tank 1. A rotating shaft is fixedly installed at the output end of the third motor 510. Connecting shafts 511 are rotatably connected to both sides of the inner wall of the water purification tank 1. Bevel gears 512 are fixedly installed on the outer surfaces of both the connecting shafts 511 and the rotating shaft. The two bevel gears 512 mesh with each other. The upper surface of the retrieval plate 503 is... A third lead screw 513 is rotatably connected to the surface via a support member. A locking block is threaded onto the outer surface of the third lead screw 513. A second scraper 514 is fixedly installed on the lower surface of the locking block. A docking post 515 is fixedly installed on one side surface of the third lead screw 513. A protrusion 516 is fixedly installed on the surface of the docking post 515. An open groove is opened on the surface of the connecting shaft 511. A recessed groove 517 is opened on the inner side wall of the open groove. The open groove is adapted to the docking post 515, and the protrusion 516 is adapted to the recessed groove 517.

[0052] In this embodiment: when it is necessary to retrieve a floating object, the operator starts the rotary motors 518 on both sides to drive the second lead screw 501 to rotate, causing the driven block 502 on the surface of the second lead screw 501 to move the retrieval plate 503 downward. At this time, the retrieval plate 503 is in a vertical state. At the same time, during the movement, the support column 504 on one side of the retrieval plate 503 slides into the interior of the L-shaped guide rail 505. As the retrieval plate 503 continues to move downward, the support column 504 slides inside the L-shaped guide rail 505. The movement causes the retrieval plate 503 to move from a vertical to a horizontal position, allowing the insertion block 507 on one side of the retrieval plate 503 to insert into the insertion groove 508 on the side surface of the other retrieval plate 503, thus locking the two retrieval plates 503 together. Then, the rotation motors 518 on both sides are activated, causing the driven block 502 to move upward. The driven block 502 drives the retrieval plate 503 on one side to move upward synchronously, moving the retrieval plate 503 to the top and simultaneously engaging the docking post 515 on the upper surface of the retrieval plate 503. Simultaneously, the connecting shaft 511 is inserted into the open groove on its surface, causing the protrusion 516 on the surface of the mating post 515 to insert into the recessed groove 517 on the inner sidewall of the open groove. Then, the third motor 510 is started to drive the rotating shaft to rotate. The rotating shaft drives the other meshing bevel gear 512 and the internal connecting shaft 511 to rotate through the bevel gear 512 on its surface. The connecting shaft 511 drives the internal mating post 515 and the third lead screw 513 at one end to rotate, causing the third lead screw 513 to rotate and drive the second scraper 5... 14. Move the second scraper 514 to scrape the floating objects on the surface of the salvage plate 503 to one side. Then start the third motor 510 to return the second scraper 514 to its original position. Then, the staff opens the box door to clean up the floating objects. After cleaning, the staff moves the pull part 509 to drive the plug block 507 to move, so that the plug block 507 is disengaged from the inside of the plug slot 508. This releases the limit on both sides of the salvage plate 503 and makes it vertical by gravity rotation, which is convenient for salvage operation.

A rotating shaft is fixedly installed at the center of one side surface of the water-dispelling blades 7. A driven gear is fixedly installed on the outer surface of the rotating shaft. A toothed chain belt 8 is meshed with the outer surface of the driven gear. A fourth motor 9 is fixedly installed on one side surface of the water purification tank 1. One end of one of the rotating shafts is fixedly installed at the output end of the fourth motor 9. A protective plate 10 is fixedly installed on the surface of the inclined flow plate 6. The surface of the protective plate 10 has several through holes.

[0054] In this embodiment: when the support column 504 slides inside the L-shaped guide rail 505 and causes the retrieval plate 503 to move from a vertical state to a horizontal state, one end of the retrieval plate 503 will scrape down the impurities accumulated at the bottom of the water purification tank 1 and be in motion. Then, the fourth motor 9 is started to drive the rotating shaft to rotate. The rotating shaft drives the driven gear on the outer surface to rotate. The toothed chain belt 8 drives the rotating shafts on both sides to rotate synchronously. At the same time, it drives the water-dispelling blade 7 on one side to rotate synchronously and cause the water to surge, causing the impurities inside to be in a turbulent state. The retrieval plate 503 retrieves the impurities and maintains the cleanliness of the bottom of the tank.

[0055] The following describes a method for using an automatically draining circulating water purification device, based on the aforementioned device: The method includes the following steps:

[0056] S1. The staff inputs the sewage into the interior of the water purification tank 1 and filters it through the filter plate 303 in the circulating filter assembly 3. After a long period of use, the filter plate 303 will be clogged by impurities in the sewage. Then, by rotating the first rotating column 302 and rotating it ninety degrees, a new filter plate 303 will be rotated into the interior of the water purification tank 1.

[0057] S2. Then the staff activates the first electric push rod 308 above the clogged filter plate 303 and causes the unblocking burrs on the surface of the squeezing plate 305 to be inserted into the surface of the filter plate 303. Then, through the setting of the automatic sewage cleaning component 4, the blockage on the surface of the filter plate 303 is scraped into the inside of the sewage storage tank 401.

[0058] S3. After filtration is completed, some floating objects will remain on the water surface. Then, the staff will start the rotary motor 518 to drive the scooping plate 503 to move vertically downward. When one end of the scooping plate 503 moves to the bottom of the water purification tank 1, the scooping plate 503 will slide along the bottom of the water purification tank 1 and make the two sides of the scooping plate 503 interlock and fix each other. Then, the rotary motor 518 will move the scooping plate 503 and scoop the floating objects in the water to the surface through the scooping plate 503. When it moves to the top, the docking column 515 is inserted into the inside of the connecting shaft 511, and the second scraper 514 is moved by the third motor 510 to scrape the floating objects on the surface of the scooping plate 503 to one side for processing.

[0059] S4. After the processing is completed, reset the second scraper 514, then open the box door on one side of the sealing box 2, pull the puller 509 to one side, so that the plug block 507 is disengaged from the inside of the plug groove 508, and then the two sides of the retrieval plate 503 will automatically rotate and be in a vertical state without the limit, and then open the valve to discharge the water source.
