[0019] By adopting the above technical solution, the first stop housing can limit the one-way rotation of the first rotating plate, and the first torsion spring is used to drive the first rotating plate to reset after rotation.

[0020] As preferred embodiment of the present invention, the processing method comprises the following steps: S1, according to the treatment method, can be divided into stirring and cleaning; S11, during stirring, activated carbon powder is fed into the hollow column from the feeding hole. As the motor runs, the first stirring rod is driven to move inside the forward and reverse thread grooves using the extrusion rod. The forward and reverse thread grooves are threaded in shape. When the extrusion rod squeezes the inner wall of the forward and reverse thread grooves, it moves along the shape of the forward and reverse thread grooves. When the first stirring rod moves, it squeezes the first double-bevel block to move it, thereby discharging the material. S12, when cleaning, the motor runs clockwise, which drives the four sets of scrapers to run in opposite or reverse directions, thereby scraping off the sand adsorbed by impurities on the surface; S2, completing the operation steps corresponding to each treatment method; S21, place sand for sand filtration inside the holding shell, pour wastewater from the surface of the sand, and after filtering by the sand, the sand filter will remove suspended matter, and the wastewater will enter the bottom shell from the holding shell. Since the inside of the feeding hole is in an inclined state, when the activated carbon powder is fed into the hollow column from the inside of the feeding hole, the motor drives the hollow column to rotate to one side, and the first stirring rod will move upward inside the positive and negative thread grooves using the extrusion rod (the first stirring rod in the figure is at the upper end of the hollow column). At this time, the hollow column drives the gear to rotate and turns the first rotating plate counterclockwise, so that the first rotating plate rotates using the first rotating rod, so the cleaning component does not move. When the first stirring rod is in the process of moving up, one side of the mounting shell will block the second flip plate, preventing the second flip plate from moving up and squeezing the first double-slope block to rotate, so the second flip plate can push the first double-slope block to move. Both sides of the first double-slope block are made of tempered plate material and are relatively smooth. At this time, the first double-slope block will drive the baffle to slide on the surface of the sliding column. During the sliding process, one side of the opening and closing plate will be squeezed by the hollow column, thereby flipping. The opening formed by the flipping is convenient for the outflow of activated carbon powder. The third torsion spring is used to drive the opening and closing plate to reset after rotation, and the hollow tube is used to prevent water leakage at the position of the third torsion spring. When the baffle When it moves to the appropriate position, the inclined surface of the second double-slope block will be squeezed by the card hole and rotated by the second rotating rod. The second double-slope block is also made of tempered plate with a smooth surface. When the baffle continues to move, the second torsion spring can drive the second double-slope block to reset, so that the second double-slope block pulls the baffle to move and hang inside the card hole, so that the position of the opening and closing plate is always opened, which is convenient for discharging. Because the convex plate will move with the baffle and be clamped inside the concave plate, the three groups of convex plates and concave plates will separate the interior of the hollow column into three parts, each of which has activated carbon powder inside, so that as the wastewater rises inside the bottom shell to the three stages, Activated carbon powder will flow out and mix with the wastewater, making the mixing more uniform. It can also prevent the activated carbon powder inside the hollow column from being left out together when the first hole is opened from the bottom, resulting in sufficient activated carbon powder at the bottom and lack of activated carbon powder at the upper end. When the first stirring rod moves to the upper end, it will push the lifting plate to move up using the spring push rod, so that the card hole is separated from the fixation of the second double-slanted block, and the telescopic spring pulls the baffle and the first double-slanted block to reset. In the whole process, the second stirring rod will also stir the sand used for sand filtration to prevent the filtered impurities from piling up and causing clogging of the filter holes. S22, when the motor runs clockwise, the gear will effectively move the first rotating plate, because the first stop shell will block one side of the first rotating plate to prevent the first rotating plate from rotating when pushed. The first torsion spring is used to drive the first rotating plate to reset after rotation. When the gear rotates, it will drive the two sets of tooth plates to move in the opposite direction, thereby driving the four sets of scrapers to scrape off the sand with excessive impurities adsorbed on the surface. The resin is encapsulated in a porous bag or capsule and put into the wastewater (ion exchange removes trace heavy metals). Finally, the ultraviolet lamp is placed inside the wastewater for disinfection to ensure that the microorganisms meet the standards.

[0021] In summary, the present invention has the following beneficial effects: When in use, place the sand for sand filtration inside the containing shell, then start the stirring component and run it counterclockwise. The stirring component will stir the sand, which can improve the use efficiency of the sand and prevent the accumulation of impurities in the sand. At the same time, the activated carbon powder will be automatically discharged from the stirring component. During the discharge process, the activated carbon powder and wastewater will be stirred and mixed to effectively adsorb organic matter. The pH value of the wastewater will then be manually adjusted to between 6 and 8. When the stirring component runs counterclockwise, the cleaning component will not run. When the stirring component runs clockwise, the cleaning component will scrape off the sand with excessive impurities adsorbed on the surface, encapsulate the resin in a porous bag or capsule, put it into the wastewater (ion exchange to remove trace heavy metals), and then put it into the ultraviolet lamp for sterilization. After the treatment is completed, open the drain port to discharge the treated wastewater. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Brief description of the usage process: When in use, place the sand for sand filtration inside the containing shell 6, then start the stirring component 5 and run it counterclockwise.

A mounting shell 524 is welded inside the lifting shell 523. A second flip plate 526 is rotatably connected inside the mounting shell 524. One end of one group of the first stirring rods 504 is welded to an extrusion rod 505; a fourth torsion spring 525 is sleeved on both sides of the second flip plate 526, and the fourth torsion spring 525 is sleeved on both sides of the second flip plate 526. The spring 525 is connected between the second flip plate 526 and the mounting shell 524 through a spring fixing piece. Three groups of sliding columns 514 are welded to the inner wall of the hollow column 502. A fixing plate 513 is welded to the middle of the surface of the sliding column 514. A telescopic spring 512 is sleeved on the surface of the sliding column 514. One end of the telescopic spring 512 is connected to a baffle 511 through a spring fixing piece, and the baffle 511 and the sliding column 514 are slidingly connected. A first double-bevel block 510 is welded to one side of the baffle 511. A third rotating rod 520 is welded on both sides of the inner wall of the baffle 511. A third torsion spring 519 is sleeved on both ends of the surface of the third rotating rod 520. The third torsion spring 519 is connected between the opening and closing plate 521 and the baffle 511 through a spring fixing piece. A hollow tube 529 is provided on the surface of the third torsion spring 519, and the hollow tube 529 is welded to the surface of the baffle 511. A convex plate 528 is welded on the upper end of the baffle 511, and the convex plate 528 and the concave plate 527 are spliced. A second rotating rod 516 is welded inside the other side of the baffle 511; both ends of the second rotating rod 516 are provided with a second torsion spring 515. The surface of the second rotating rod 516 is rotatably connected to the first flip plate 517, and the second torsion spring 515 is connected to the first flip plate 517 through a spring fixing piece. 17 and the baffle 511, a second double-slope block 518 is welded to the upper end of the first flip plate 517; an inclined plate 530 is welded to one side of the inner wall of the hollow column 502, and two groups of spring push rods 508 are bolted to the lower end of the inclined plate 530, and the piston ends of the two groups of spring push rods 508 are commonly bolted to the lifting plate 509, and three groups of clamping holes 522 are opened on the surface of the lifting plate 509, and the clamping holes 522 and the second double-slope block 518 are detachable. The lower end of the hollow column 502 is fixedly connected to the rotating shaft 507, and the rotating shaft 507 is rotatably connected to the middle part of the bottom of the bottom shell 1, and two groups of second stirring rods 506 are welded to the upper end of the hollow column 502.

[0028] Brief description of the usage process: Place sand for sand filtration inside the holding shell 6, pour wastewater from the surface of the sand, and after being filtered by the sand, the sand filter will remove suspended matter. As the wastewater enters the bottom shell 1 from the holding shell 6, since the inside of the feeding hole 503 is in an inclined state, when the activated carbon powder is fed into the hollow column 502 from the inside of the feeding hole 503, the motor 501 drives the hollow column 502 to rotate counterclockwise, and at this time, the first stirring rod 504 uses the extrusion rod 505 to move upward inside the forward and reverse thread groove 401 (as shown in FIG. Figure 2 As shown), at this time, since the hollow column 502 drives the gear 403 to rotate and toggle the first rotating plate 407 counterclockwise, the first rotating plate 407 is rotated by the first rotating rod 409, so the cleaning component 4 does not operate. When the first stirring rod 504 is in the process of moving up, the side of the mounting shell 524 blocks the second flip plate 526, preventing the second flip plate 526 from moving up and squeezing the first double-bevel block 510 to rotate, so the second flip plate 526 can push the first double-bevel block 510 to move. The two sides of the first double-bevel block 510 are made of tempered plate material and are relatively smooth. At this time, the first double-bevel block 5 10 drives the baffle 511 to slide on the surface of the sliding column 514. During the sliding process, one side of the opening and closing plate 521 will be squeezed by the hollow column 502, thereby flipping. The opening formed by the flipping is convenient for the outflow of activated carbon powder. The third torsion spring 519 is used to drive the opening and closing plate 521 to reset after rotation. The hollow tube 529 is used to prevent water leakage at the position of the third torsion spring 519. When the baffle 511 moves to the appropriate position, the inclined surface of the second double-bevel block 518 is squeezed by the card hole 522 and rotated by the second rotating rod 516. The second double-bevel block 518 is also made of tempered plate with a smooth surface. When the baffle 511 continues to move, the second The torsion spring 515 can drive the second double-slope block 518 to reset, so that the baffle 511 pushes the second double-slope block 518 to move and hang inside the clamping hole 522, so that the position of the opening and closing plate 521 is always open, which is convenient for discharging. Because the convex plate 528 will follow the baffle 511 to move and be clamped inside the concave plate 527, at this time, the three groups of convex plates 528 and concave plates 527 will separate the interior of the hollow column 502 into three parts, each of which has activated carbon powder inside. This ensures that as the wastewater rises to the three stages inside the bottom shell 1, activated carbon powder will flow out and mix with the wastewater, making the mixing more uniform, and also preventing When the first hole is opened from the bottom, all the activated carbon powder inside the hollow column 502 will be left out, resulting in sufficient activated carbon powder at the bottom and a lack of activated carbon powder at the upper end. When the first stirring rod 504 moves to the upper end, it will push the lifting plate 509 to move upward using the spring top rod 508, so that the card hole 522 is separated from the fixation of the second double-slope block 518, and the telescopic spring 512 pulls the baffle 511 and the first double-slope block 510 to reset. In the whole process, the second stirring rod 506 will also stir the sand used for sand filtering to prevent the filtered impurities from piling up and causing the filter holes to be blocked.

[0029] Example 3: Based on Example 2, Figure 6-7 、 Figure 9-11 The cleaning assembly 4 includes a gear 403 and a limit shell 402. The gear 403 is welded to the upper end of the surface of the hollow column 502. The two groups of limit shells 402 are welded to the upper end of the containing shell 6, and the two groups of limit shells 402 are located on both sides of the gear 403. The two groups of limit shells 402 are slidably connected to the inside of the two groups of limit shells 402. The tooth plates 406 and the gear 403 are meshed and connected. One end of one side of the tooth plate 406 is welded with three groups of first stop shells 410; the first stop shell 411 is welded with a rotating Rod, the surface of the rotating rod is rotatably connected to the first rotating plate 407, both ends of the rotating rod are sleeved with a first torsion spring 408, and the first spring is connected between the first rotating plate 407 and the first stop shell 410 through a spring fixing member, one end of one side of the tooth plate 406 is welded with an arc rod 405, and the other end of the arc rod 405 and the other end of the tooth plate 406 are welded with a scraper 404, the inner wall of the bottom shell 1 is provided with a positive and negative thread groove 401, and the positive and negative thread groove 401 is in a sliding connection with the extrusion rod 505.

[0030] Brief description of the usage process: When the motor 501 runs clockwise, the gear 403 will effectively shift the first rotating plate 407, because the first stop shell 410 will block one side of the first rotating plate 407 to prevent the first rotating plate 407 from rotating when pushed. The first torsion spring 408 is used to drive the rotated first rotating plate 407 to reset. When the gear 403 rotates, it will drive the two sets of tooth plates 406 to move in the opposite direction, thereby driving the four sets of scrapers 404 to scrape off the sand with excessive impurities adsorbed on the surface. The resin is encapsulated in a porous bag or capsule and put into the wastewater for ion exchange to remove trace heavy metals. Finally, the ultraviolet lamp is placed inside the wastewater for disinfection to ensure that the microorganisms meet the standards.

[0031] like Figure 1-11 As shown, based on Examples 1-3, the present invention provides a technical solution, and the operation method includes the following steps: S1, according to the treatment method, can be divided into stirring and cleaning; S11, during stirring, the activated carbon powder is put into the hollow column 502 from the position of the feeding hole 503. As the motor 501 runs, it will drive the first stirring rod 504 to move inside the forward and reverse thread groove 401 using the extrusion rod 505. The forward and reverse thread groove 401 is in a threaded shape. When the extrusion rod 505 squeezes the inner wall of the forward and reverse thread groove 401, it will move along the shape of the forward and reverse thread groove 401. When the first stirring rod 504 is moving, it will squeeze the first double-bevel block 510 to make it move, thereby discharging the material.

[0032] S12, during cleaning, the motor 501 runs clockwise, driving the four sets of scrapers 404 to run in opposite or reverse directions, thereby scraping off the sand with impurities adsorbed on the surface.

[0033] S2, completing the operation steps corresponding to each treatment method; S21, place sand for sand filtration inside the holding shell 6, pour wastewater from the surface of the sand, and after filtering by the sand, the sand filter will remove suspended matter, and the wastewater will enter the bottom shell 1 from the holding shell 6. Since the inside of the feeding hole 503 is in an inclined state, when the activated carbon powder is fed into the hollow column 502 from the inside of the feeding hole 503, the motor 501 drives the hollow column 502 to rotate to one side, and at this time, the first stirring rod 504 is moved upward inside the positive and negative thread groove 401 by using the extrusion rod 505 (the first stirring rod 504 in the figure is at the upper end of the hollow column 502). At this time, since the hollow column 502 drives the gear 403 to rotate and toggles the first rotating plate 407 counterclockwise, the first rotating plate 407 is rotated by the first rotating rod 409, so the cleaning component 4 is cleaned. It will not run. When the first stirring rod 504 is moving upward, one side of the mounting shell 524 will block the second flip plate 526, preventing the second flip plate 526 from moving upward and squeezing the first double-slope block 510 to rotate. Therefore, the second flip plate 526 can push the first double-slope block 510 to move. The two sides of the first double-slope block 510 are made of tempered plate with a smooth surface. At this time, the first double-slope block 510 will drive the baffle 511 to slide on the surface of the sliding column 514. During the sliding process, one side of the opening and closing plate 521 will be squeezed by the hollow column 502, thereby flipping. The opening formed by the flipping is convenient for the outflow of activated carbon powder. The third torsion spring 519 is used to drive the opening and closing plate 521 to reset after rotation, and the hollow tube 529 is used to prevent the third torsion spring 519 from When the baffle 511 moves to the appropriate position, the inclined surface of the second double-slope block 518 will be squeezed by the card hole 522 and rotated by the second rotating rod 516. The second double-slope block 518 is also made of tempered plate with a smooth surface. When the baffle 511 continues to move, the second torsion spring 515 can drive the second double-slope block 518 to reset, so that the second double-slope block 518 pulls the baffle 511 to move and hang inside the card hole 522, so that the position of the opening and closing plate 521 is always opened, which is convenient for discharging. Because the convex plate 528 will follow the baffle 511 to move and be clamped inside the concave plate 527, at this time, the three groups of convex plates 528 and concave plates 527 will separate the interior of the hollow column 502 into three parts, each of which has activated carbon powder inside, so that as the baffle 511 continues to move, the second double-slope block 518 can be driven to reset, so that the second double-slope block 518 can pull the baffle 511 to move and hang inside the card hole 522, so that the position of the opening and closing plate 521 is always opened, which is convenient for discharging. When the wastewater rises to the third stage inside the bottom shell 1, activated carbon powder will flow out and mix with the wastewater, making the mixing more uniform. It can also prevent the activated carbon powder inside the hollow column 502 from being left out together when the first hole is opened from the bottom, resulting in sufficient activated carbon powder at the bottom and insufficient activated carbon powder at the upper end. When the first stirring rod 504 moves to the upper end, it pushes the lifting plate 509 to move upward using the spring push rod 508, thereby disengaging the clamping hole 522 from the fixation of the second double-slope block 518, causing the telescopic spring 512 to pull the baffle 511 and the first double-slope block 510 to reset. In the whole process, the second stirring rod 506 also stirs the sand used for sand filtration to prevent the filtered impurities from piling up and causing clogging of the filter holes. S22, when the motor 501 runs clockwise, the gear 403 will effectively shift the first rotating plate 407, because the first stop shell 410 will block one side of the first rotating plate 407 to prevent the first rotating plate 407 from rotating when being pushed. The first torsion spring 408 is used to drive the first rotating plate 407 to reset after rotation. When the gear 403 rotates, it will drive the two sets of tooth plates 406 to move in the opposite direction, thereby driving the four sets of scrapers 404 to scrape off the sand with excessive impurities adsorbed on the surface, encapsulate the resin in a porous bag or capsule, and put it into the wastewater for ion exchange to remove trace heavy metals. Finally, the ultraviolet lamp is placed inside the wastewater for disinfection to ensure that the microorganisms meet the standards.

9. A method for treating electroplating wastewater for ultra-clean discharge according to any one of claims 1 to 8, characterized in that: The method of use comprises the following steps. S1, according to the treatment method, can be divided into stirring and cleaning; S11, during stirring, the activated carbon powder is fed into the hollow column (502) from the feeding hole (503), and as the motor (501) runs, the first stirring rod (504) is driven to move inside the positive and negative thread groove (401) using the extrusion rod (505), and the positive and negative thread groove (401) is in a threaded shape. When the extrusion rod (505) squeezes the inner wall of the positive and negative thread groove (401), it moves along the shape of the positive and negative thread groove (401). When the first stirring rod (504) moves, it squeezes the first double-bevel block (510) to move it, thereby discharging the material. S12, during cleaning, the motor (501) runs clockwise, driving the four sets of scrapers (404) (404) to run in opposite or reverse directions, thereby scraping off the sand adsorbed with impurities on the surface. S2, completing the operation steps corresponding to each treatment method; S21, placing sand for sand filtration inside the holding shell (6), pouring wastewater from the surface of the sand, filtering the sand, and removing suspended solids, as the wastewater enters the bottom shell (1) from the holding shell (6), since the inside of the feeding hole (503) is in an inclined state, when the activated carbon powder is fed into the hollow column (502) from the inside of the feeding hole (503), the motor (501) drives the hollow column (502) to rotate to one side, and at this time, the first stirring rod (504) is moved upward inside the positive and negative thread groove (401) by using the extrusion rod (505) (the first stirring rod (504) in the figure is at the upper end of the hollow column (502)). At this time, the hollow column (502) drives the gear (403) to rotate and toggles the first rotating plate (407) counterclockwise. , so that the first rotating plate (407) rotates using the first rotating rod (409), so the cleaning component (4) does not run. When the first stirring rod (504) is in the process of moving up, the side of the mounting shell (524) will block the second flip plate (526), ​​preventing the second flip plate (526) from moving up and squeezing the first double-bevel block (510) when rotating, so the second flip plate (526) can push the first double-bevel block (510) to move. The two sides of the first double-bevel block (510) are made of tempered plate material and are relatively smooth. At this time, the first double-bevel block (510) will drive the baffle (511) to slide on the surface of the sliding column (514). During the sliding process, one side of the opening and closing plate (521) will be squeezed by the hollow column (502), thereby flipping, and the flip shape The opening is convenient for the outflow of activated carbon powder. The third torsion spring (519) is used to drive the opening and closing plate (521) to reset after rotation. The hollow tube (529) is used to prevent water leakage at the position of the third torsion spring (519). When the baffle (511) moves to a suitable position, the inclined surface of the second double-bevel block (518) is squeezed by the clamping hole (522) and rotated by the second rotating rod (516). The second double-bevel block (518) is also made of a tempered plate with a smooth surface. When the baffle (511) continues to move, the second torsion spring (515) can drive the second double-bevel block (518) to reset, so that the second double-bevel block (518) pulls the baffle (511) to move and hang inside the clamping hole (522), so that the position of the opening and closing plate (521) is always opened. It is convenient to discharge the material, because the convex plate (528) will follow the baffle (511) to move and be clamped inside the concave plate (527). At this time, the three groups of convex plates (528) and concave plates (527) will separate the interior of the hollow column (502) into three parts, and each part has activated carbon powder inside. In this way, it can be ensured that as the wastewater rises to three stages inside the bottom shell (1), activated carbon powder will flow out and mix with the wastewater, making the mixing more uniform. It can also prevent the activated carbon powder inside the hollow column (502) from being left out together when the first hole is opened from the bottom, resulting in sufficient activated carbon powder at the bottom and lack of activated carbon powder at the top. When the first stirring rod (504) moves to the upper end, it will push the lifting plate (509) to move up using the spring push rod (508).As a result, the locking hole (522) is separated from the fixation of the second double-slope block (518), and the telescopic spring (512) pulls the baffle (511) and the first double-slope block (510) to reset. In addition, during the entire process, the second stirring rod (506) also stirs the sand used for sand filtration to prevent the filtered impurities from piling up and causing the filter holes to be blocked. S22, when the motor (501) runs clockwise, the gear (403) will effectively shift the first rotating plate (407), because the first stop shell (410) will block one side of the first rotating plate (407) to prevent the first rotating plate (407) from rotating when being pushed. The first torsion spring (408) is used to drive the first rotating plate (407) to reset after rotation. When the gear (403) rotates, it will drive the two sets of tooth plates (406) to move in the opposite direction, thereby driving the four sets of scrapers (404) to scrape off the sand with excessive impurities adsorbed on the surface. The resin is encapsulated in a porous bag or capsule and put into the wastewater (ion exchange removes trace heavy metals). Finally, the ultraviolet lamp is placed inside the wastewater for disinfection to ensure that the microorganisms meet the standards.
