This agitation disperses impurities in the wastewater in the coarse filtration tank, allowing it to flow quickly into the fine filtration tank. After agitation, the wastewater in the fine filtration tank reacts rapidly with the flocculant to form precipitates, which are then settled and discharged. This staged wastewater treatment significantly reduces the time required for water treatment, resulting in higher efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This embodiment provides a technical solution: a high-efficiency water treatment device, including a filter tank 1, a sand filter mechanism 4, and a high-efficiency staged stirring mechanism 5;

[0027] Filter tank 1: A coarse filter tank 2 is located in the middle of the filter tank 1, and a fine filter tank 3 is located on the right side of the filter tank 1. Sediment guide boxes 7 are respectively located on the lower side of the coarse filter tank 2 and the fine filter tank 3. A controller 11 is located on the outside of the equipment. The input terminal of the controller 11 is electrically connected to an external power source. A garbage collection tank 6 is located on the left side inside the filter tank 1. The upper side of the garbage collection tank 6 is connected to the upper side of the coarse filter tank 2. A grid plate 8 is located on the upper side of the coarse filter tank 2. A return pipe 9 is located on the front side of the garbage collection tank 6. The outlet on the right side of the return pipe 9 corresponds vertically to the upper side of the coarse filter tank 2. A sewage pump is connected in series in the middle of the return pipe 9. The input terminal of the sewage pump is electrically connected to the output terminal of the controller 11. Sewage outlet pipes are respectively located on the outer sides of the two sediment guide boxes 7. The ends of the two sewage outlet pipes are respectively connected to external sewage suction equipment. A liquid outlet pipe 10 is located on the upper right side of the fine filter tank 3. The lower end of the outlet pipe 10 is connected to an external water collection device, and then the water to be treated can be discharged into the coarse filter tank 2 until the water level in the coarse filter tank 2 rises to the upper side of the bar screen 8. At this time, a large amount of garbage in the sewage will be separated by the bar screen 8. As the water level rises, domestic garbage will flow into the garbage collection tank 6 along with some sewage. During the process of adding water to the coarse filter tank 2, a small amount of sewage will flow into the garbage collection tank 6 along with the floating garbage. The floating garbage in the garbage collection tank 6 will still stay on the liquid surface. At this time, the controller 11 can be adjusted to start the sewage pump to pump out the sewage on the lower side of the garbage collection tank 6 and discharge it back into the coarse filter tank 2. This process occurs when the sewage first receives sand filtration. When there is too much garbage in the garbage collection tank 6, the upper cover of the garbage collection tank 6 needs to be opened to discharge the floating garbage.

[0028] Sand filtration mechanism 4 includes a double-layer partition plate 41, which is disposed between the coarse filtration tank 2 and the fine filtration tank 3. The sand filtration mechanism 4 also includes an iron mesh frame 42, a right-side sliding frame groove 43, a plug-in plate 44, a filter screen 45, and a nylon bag placement groove 46 (the filter screen 45 can be made of high-density polyethylene membrane to prevent sewage backflow). The iron mesh frame 42 is fixedly connected to the left side of the double-layer partition plate 41, and the right-side sliding frame groove 43 is fixedly connected to the right side of the double-layer partition plate 41. A plug-in plate 44 is inserted into the inside of the right-side sliding frame groove 43. The sides of the plug-in plate 44 are aligned front and rear. The device is equipped with a filter screen 45 and symmetrical nylon bag placement slots 46 on the upper side of the double-layer partition plate 41. Before using the water treatment equipment, a certain amount of manganese sand can be filled into the nylon bags and then placed inside the nylon bag placement slots 46. As the water level in the coarse filtration tank 2 rises, the sewage will flow into the nylon bag placement slots 46 and then into the fine filtration tank 3. The water flowing into the fine filtration tank 3 will be filtered by the manganese sand to remove larger impurities and complete the primary sand filtration treatment. At this time, the turbid water will remain in the coarse filtration tank 2, and the water with the impurities removed will remain in the fine filtration tank 3.

[0029] The high-efficiency grading and stirring mechanism 5 includes a first rotating rod 51, a first stirring blade 52, a second rotating rod 53, a second stirring blade 54, a first gear 55, and a second gear 56. The first rotating rod 51 is rotatably connected to the middle of the left side wall of the coarse filtration tank 2, and the right end of the first rotating rod 51 is rotatably connected to the middle of the left side wall of the double-layer partition plate 41. The second rotating rod 53 is rotatably connected to the middle of the right side wall of the fine filtration tank 3, and the left end of the second rotating rod 53 is rotatably connected to the right side wall of the double-layer partition plate 41. The outer arc surface of the first rotating rod 51 is fixedly connected to the uniformly distributed first stirring blade 52, and the outer arc surface of the second rotating rod 53 is fixedly connected to the uniformly distributed second stirring blade 54. The right end of the first rotating rod 51 is fixedly connected to the second gear 56, and the left end of the second rotating rod 53 is fixedly connected to the second gear 56. The high-efficiency classifying and stirring mechanism 5 includes a first gear 55, which meshes with a second gear 56. The high-efficiency classifying and stirring mechanism 5 also includes a sediment discharge assembly 58, which comprises a third rotating rod 581, a third stirring plate 582, a first sprocket 583, a second sprocket 584, and a chain 585. The third rotating rod 581 is rotatably connected between the front and rear inner walls of the two sediment guide boxes 7. The outer arc surfaces of the two third rotating rods 581 are fixedly connected to uniformly distributed third stirring plates 582. The front end of the left third rotating rod 581 is fixedly connected to the second sprocket 584, and the front end of the right third rotating rod 581 is fixedly connected to the first sprocket 583. The first sprocket 583 and the second sprocket 584 are connected by a chain 585. This high-efficiency classifying and stirring mechanism... The primary mixing mechanism 5 also includes a mixing motor 57, which is located in the middle of the right side of the fine filter tank 3. The output shaft of the mixing motor 57 is fixedly connected to the right end of the second rotating rod 53. The input end of the mixing motor 57 is electrically connected to the output end of the controller 11. A sludge removal motor 12 is provided on the rear side of the filter tank 1. The output shaft of the sludge removal motor 12 is fixedly connected to the rear end of the third rotating rod 581 on the right side. The input end of the sludge removal motor 12 is electrically connected to the output end of the controller 11. At this time, flocculant can be added to the fine filter tank 3 in a timed and quantitative manner. Then, the controller 11 can be adjusted to rotate the output shaft of the mixing motor 57, thereby driving the second rotating rod 53 to rotate. In turn, the first rotating rod 51 is driven to rotate in reverse through the first gear 55 and the second gear 56. The system rotates, stirring both the wastewater in the coarse filtration tank 2 and the water in the fine filtration tank 3. The stirring rate in the coarse filtration tank 2 is lower than that in the fine filtration tank 3, allowing the wastewater to flow slowly into the fine filtration tank 3. The stirring of the wastewater in the coarse filtration tank 2 quickly mixes the sludge with the wastewater. This water then flows into the fine filtration tank 3, where it reacts with the flocculant. Small, unfiltered particles react with the flocculant to form fine sludge. Once the water and flocculant in the fine filtration tank 3 are fully mixed, stirring is stopped, and sedimentation begins. Large particles that cannot be dispersed in the coarse filtration tank 2 settle downwards into the sediment guide box 7 on the left.The fine sludge produced after flocculation in the fine filtration tank 3 will also settle downwards until it settles into the sediment guide box 7 on the right. At this point, the external suction equipment can be adjusted to extract the sludge from the sediment guide box 7. During this process, the controller 11 can be adjusted to operate the sludge removal motor 12. The output shaft of the sludge removal motor 12 rotates, which in turn drives the third rotating rod 581 on the right to rotate. This, in turn, drives the third rotating rod 581 on the left to rotate through the first sprocket 583, the second sprocket 584, and the chain 585. At this time, the third stirring plates 582 in both sediment guide boxes 7 will also stir and disperse the sediment, allowing it to be quickly sucked out by the external suction equipment.

[0030] The working principle of the high-efficiency water treatment equipment provided by this utility model is as follows: Before using the water treatment equipment, a certain amount of manganese sand can be filled into a nylon bag and placed inside the nylon bag placement groove 46. Then, the water to be treated can be discharged into the coarse filtration tank 2 until the water level in the coarse filtration tank 2 rises to the upper side of the grid plate 8. At this time, a large amount of garbage in the sewage will be separated by the grid plate 8. As the water level rises, domestic garbage will flow into the garbage collection tank 6 along with some sewage. As the water level in the coarse filtration tank 2 rises, this sewage will flow into the nylon bag placement groove 46 and then into the fine filtration tank 3. The water flowing into the fine filtration tank 3 will be filtered by manganese sand, removing larger impurities and thus completing the primary sand filtration treatment. At this time, the turbid water... Water remains in the coarse filtration tank 2, while the water from which impurities are removed remains in the fine filtration tank 3. At this point, flocculant can be added to the fine filtration tank 3 at regular intervals and in measured quantities. Then, the controller 11 is adjusted, causing the output shaft of the stirring motor 57 to rotate, which in turn drives the second rotating rod 53 to rotate. This, in turn, drives the first rotating rod 51 to rotate in the opposite direction via the first gear 55 and the second gear 56. During this process, the wastewater in the coarse filtration tank 2 is stirred, and the water in the fine filtration tank 3 is also stirred. The stirring rate in the coarse filtration tank 2 is lower than that in the fine filtration tank 3, allowing the wastewater in the coarse filtration tank 2 to slowly flow into the fine filtration tank 3. The stirring of the wastewater in the coarse filtration tank 2 quickly mixes the sludge with the wastewater, and this water then flows into the fine filtration tank 3 after filtration. In the fine filtration tank 3, the water reacts with the flocculant. Small, unfiltered particles react with the flocculant to form fine sludge. Once the water and flocculant in the fine filtration tank 3 are fully mixed, stirring can be stopped, and sedimentation can begin. Large particles in the coarse filtration tank 2 that cannot be dispersed will settle downwards into the sedimentation guide box 7 on the left. The fine sludge produced after flocculation in the fine filtration tank 3 will also settle downwards until it reaches the sedimentation guide box 7 on the right. At this point, the external suction equipment can be activated to remove the sludge from the sedimentation guide box 7. During this process, the controller 11 can be activated, and the sludge removal motor 12 will operate. The output shaft of the sludge removal motor 12 will rotate, thereby driving the third rotating rod 581 on the right to rotate, which in turn drives the first sprocket 5... 83. The second sprocket 584 and chain 585 drive the third rotating rod 581 on the left to rotate. At this time, the third stirring plate 582 in the two sediment guide boxes 7 will also stir and disperse the sediment so that it can be quickly sucked out by the external sewage suction equipment. During the process of adding water to the coarse filter tank 2, a small amount of sewage will flow into the garbage collection tank 6 along with the floating garbage. The floating garbage in the garbage collection tank 6 will still stay on the liquid surface. At this time, the controller 11 can be adjusted to start the sewage pump to pump out the sewage in the lower part of the garbage collection tank 6 and discharge it back into the coarse filter tank 2. This process occurs when the sewage first receives sand filtration. When there is too much garbage in the garbage collection tank 6, the upper cover of the garbage collection tank 6 needs to be opened to discharge the floating garbage.

[0031] It is worth noting that the core chip of the controller 11 disclosed in the above embodiments is a PLC microcontroller, specifically the STM32. The stirring motor 57, the sewage pump, and the sludge removal motor 12 can be freely configured according to the actual application scenario. It is recommended that the stirring motor 57 be a Y132S-4 model three-phase asynchronous motor, the sewage pump be a 50WQ15-15-1.5 type non-clogging submersible sewage pump, and the sludge removal motor 12 be a YZ-112M-6 / 1.5Kw model three-phase asynchronous motor. The controller 11 controls the operation of the stirring motor 57, the sewage pump, and the sludge removal motor 12 using methods commonly used in the prior art.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
