[0095] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0096] Reference Figure 1-24 A self-cleaning water treatment device includes a rectangular tank with a sedimentation zone 1, an aeration zone 2, a flocculation zone 3, and an effluent zone 4 connected sequentially from left to right. Accordingly, the sedimentation zone 1 collects and cleans larger sediments; the aeration zone 2 introduces suitable gas to react with the incoming water; the flocculation zone 3 adds chemical agents to carry out flocculation and sedimentation, and is then cleaned; the effluent zone 4 performs final treatment before discharging the water; the various zones work together to achieve the treatment of the incoming water.

[0097] In some embodiments, a water inlet filter 5 is provided at the upper left side of the sedimentation zone 1.

[0098] Therefore, by adding the inlet filter 5, the inlet water is filtered and then treated in the pool; this can prevent large debris from entering the pool and affecting each process, and facilitate subsequent treatment operations.

[0099] Meanwhile, a slag discharge port 51 is provided on the left side of the water inlet filter 5 to discharge the filtered impurities.

[0100] Specifically, the water inlet filter 5 is a U-shaped shell with an open top and a mesh bottom.

[0101] Wastewater enters the hopper from the top of the inlet filter hopper 5; after filtration, it is discharged from the bottom mesh and enters the pool body.

[0102] It is understandable that the bottom mesh of the inlet filter 5 is located above the sedimentation zone 1, and the slag discharge port 51 extends to the outside of the tank.

[0103] like Figure 1 , 2 As shown in Figures 5 and 6, the lower left side wall of the water inlet filter 5 forms a slag discharge port 51 to discharge debris from the left side to the outside. In addition, it is understood that a slag hopper, collection box or other structure can be set below the slag discharge port 51 to collect and store the discharged debris, and after a certain amount is reached, it can be transported away for treatment.

[0104] In some embodiments, an inclined guide plate 52 tangent to the lower bottom mesh is provided below the water inlet filter 5 to better guide the discharge of debris and control the discharge position.

[0105] The inclined guide plate 52 is tilted to the lower left; vertically arranged baffles are set on its front and rear sides to form a slag discharge channel.

[0106] It should be noted that the portion of the inclined guide plate 52 extending outside the pool body does not have openings; that is, Figure 5 , 6 The left half of the middle section is designed to prevent moisture from leaking out of the debris.

[0107] In some embodiments, a baffle plate 53 is rotatably disposed above the inclined guide plate 52.

[0108] In normal operation, the left side of the baffle plate 53 is raised above the horizontal position, thus forming a high left side shape, which effectively blocks water and prevents water from flowing out from the left side during the filtration process.

[0109] Correspondingly, when slag needs to be discharged, the left side of the baffle plate 53 moves downward to fit the inclined guide plate 52, thereby forming an inclined shape to facilitate the discharge of debris.

[0110] For the connection configuration, a rotating shaft is fixedly installed at the inner end of the baffle plate 53, which is rotatably connected to the inclined guide plate 52 or the slag discharge channel.

[0111] When connected with the slag discharge channel, the two ends of the rotating shaft are inserted into the side baffles and rotated with them; when connected with the inclined guide plate 52, multiple sleeves are fixedly installed on the inclined guide plate 52, and the rotating shaft is inserted into them and rotated with them.

[0112] Furthermore, a rubber strip 54 is installed above the right edge of the baffle plate 53, and the lower right end of the rubber strip 54 is connected to the inclined guide plate 52; as shown Figure 6 As shown, the rubber strip 54 seals the gap between the water-blocking plate 53 and the inclined guide plate 52, forming a better water-blocking effect.

[0113] at the same time:

[0114] The rotating shaft of the baffle plate 53 is connected to the power component to drive the baffle plate 53 to rotate, so as to form a water-blocking or slag-discharging form.

[0115] Alternatively, a torsion spring or spring mechanism may be provided below the baffle plate 53 to lift the baffle plate 53 upward; and after the debris accumulates to a certain amount, the baffle plate 53 is pressed down, and the debris is discharged; and after the debris decreases, the baffle plate 53 is raised again.

[0116] Understandably, the first method offers greater controllability, allowing for timed slag removal; the second method is simpler but may experience issues such as abnormal rebound or poor slag removal. The choice should be made based on the actual environment and the amount of debris entering the water.

[0117] Of course, it is also possible to set the water baffle 53 to a fixed position on the left side that is too high; however, this will result in some debris accumulating.

[0118] In some embodiments, a dial wheel 55 is provided inside the water inlet filter 5; the dial wheel 55 is used to push out debris more smoothly, avoiding accumulation and blockage.

[0119] Preferably, the blades of the dial 55 are in the form of a mesh, which makes it lighter; and it can prevent water from accumulating between the dial blades and being thrown out.

[0120] Correspondingly, the central shaft of the dial 55 extends to the outside of the inlet filter 5 and is connected to the power unit.

[0121] Preferably, pulleys are provided at both ends of the central shaft of the dial 55, which are driven by a motor.

[0122] In some embodiments, a guide plate 56 is provided at an inward offset position below the water inlet filter 5.

[0123] The guide plate 56 guides the water falling from a height, reducing the direct impact and disturbance of the water on the sedimentation zone 1.

[0124] Specifically, such as Figure 2 , 7 As shown; the guide plate 56 includes: a vertical plate 561, a bottom plate 562, and a first arc plate 563 connecting the two, forming a comprehensive guide.

[0125] The vertical plate 561 has its upper end higher than the water surface to prevent the incoming water from flowing directly backward, blocking it entirely to the left of the guide plate 56; the bottom plate 562 extends downward at an angle to the side (i.e., the left side) closer to the inlet filter 5, and maintains a gap with the inner wall of the pool to form a downward water flow at this point; the first arc plate 563 forms an arc-shaped connection shape, which has good impact resistance, can better guide the direction of water flow, can reduce the adhesion of dirt, and is also easy to clean.

[0126] In some embodiments, a brush rod 57 is provided on the inner side of the guide plate 56.

[0127] The brush rod 57 is long and narrow, with bristles and a brush cloth on its outer surface. The brush rod 57 is attached to the inner surface of the guide plate 56 and is driven and moved by the belt 58 to clean the guide plate 56.

[0128] like Figure 7 , 8 As shown in Figure 9, the belt 58 is limited by the guide wheel installed inside the pool body, and is powered by the drive wheel to move the brush rod 57 to fit the inner surface of the guide plate 56.

[0129] Understandably, with the guide wheel in place, a portion of the belt is parallel to the guide plate 56; a fixing seat or other structure is provided on the outer ring side of the belt to connect the two ends of the brush rod 57 and connect it to the belt drive; as the brush rod 57 moves, it cleans the guide plate 56; at the same time, the drive motor can be controlled to rotate in both directions to obtain a better cleaning effect.

[0130] In some embodiments, the sedimentation zone 1 and the aeration zone 2 are separated by an overflow plate 11; after sedimentation, the influent enters the aeration zone 2 through the upper end of the overflow plate 11.

[0131] Furthermore, a vertically adjustable height plate 12 is provided on the side of the overflow plate 11 to cooperate with the overflow plate 11 and adjust the overflow height.

[0132] Specifically, a vertical track is provided on the side of the overflow plate 11, into which the height adjustment plate 12 is placed; at the same time, the height adjustment plate 12 can be manually moved and locked, or pulled up and down by an electric component.

[0133] In some embodiments, a sludge extraction component 6 is provided at the bottom of the sedimentation zone 1 to extract the sediment.

[0134] Specifically, such as Figure 2 , 3 As shown in Figures 4, 10, 12, and 13; the impurity extraction component 6 includes: two symmetrically arranged first inclined plates 61, a sinking trough 62 located in the middle of the two first inclined plates 61, and an impurity extraction pipe 63 communicating with the sinking trough 62.

[0135] The first inclined plates 61 on both sides cooperate with the settling trough 62 to form a central collection state; more sediment falls into the settling trough 62 and is discharged through the impurity extraction pipe 63; and by setting the shape of the settling trough, the disturbance range during impurity extraction can be significantly reduced.

[0136] Furthermore, the scavenging pipe 63 includes a main pipe 631 and a plurality of branch pipes 632 connected to the main pipe 631.

[0137] The main pipe 631 extends to the outside of the pool and is connected to the suction device; the branch pipe 632 connects to the inside of the sink trough 62 for distributed suction.

[0138] In the specific setup, the branch pipe 632 is connected to the side and / or bottom of the sinking trough 62; this allows for impurity extraction from multiple sides, resulting in better performance.

[0139] In some embodiments, a scraper assembly 64 corresponding to the first inclined plate 61 is further provided above the impurity extraction assembly 6.

[0140] As mentioned above, the first inclined plate 61 and the sinking trough 62 work together to form a central collection state, but inevitably sediment and accumulation will occur on the first inclined plate 61; therefore, the first inclined plate 61 needs to be cleaned.

[0141] Specifically, such as Figure 10 , 11 As shown in Figures 1 and 12; the scraper assembly 64 includes: two triangular scrapers 641 that fit against the first inclined plate 61, two side rails 642 that guide the triangular scrapers 641, and a linkage mechanism that drives the triangular scrapers 641.

[0142] The track 642 is set on the side wall of the pool and is parallel to the first inclined plate 61. At the same time, at both ends of the triangular scraper 641, there are not less than two fixing blocks 643 that slide with the track 642 to guide and limit the triangular scraper 641 so that it fits against the upper surface of the first inclined plate 61.

[0143] Meanwhile, connecting rods 644 are hinged above the two triangular scrapers 641 respectively, and the other end of the connecting rods 644 is hinged to the lifting rod 645; a power telescopic rod is installed on the side wall of the pool to vertically drive the lifting rod 645; by adjusting the extension and retraction of the power telescopic rod, the lifting rod 645 is moved, thereby the connecting rods 644 pull the two triangular scrapers 641 closer or further away to carry out cleaning operations.

[0144] Understandably, the actual cleaning operation is to push the attached material into the central sink 62 and remove it.

[0145] In some embodiments, a bottom flow guide plate 21 is provided on the side of the aeration zone 2 near the sedimentation zone 1 to control the aeration water flow so that it flows from bottom to top for better aeration treatment.

[0146] Specifically, the upper end of the bottom flow guide plate 21 is higher than the water surface, and the lower end is separated from the bottom surface of the pool, so as to guide the water flow to form bottom flow.

[0147] In some embodiments, the aeration zone 2 is provided with an aeration component 7.

[0148] The aeration component 7 includes multiple aeration pipes 71 arranged in an array and vertically; at the same time, an air supply chamber 72 is set at the bottom of the pool to connect all the aeration pipes 71.

[0149] It is understandable that the air supply chamber 72 is connected to the external air supply component; and the upper surface of the air supply chamber 72 is not higher than the inner bottom wall of the pool body, reducing the dead corners for cleaning the bottom surface.

[0150] In this embodiment, by setting the aeration pipe 71 to a vertical arrangement, it can fully cover different depths of the entire water area; and, in the vertical setting state, the aeration pipe 71 itself is less likely to be contaminated or attached.

[0151] In some embodiments, a sliding cleaning ring 73 is fitted onto the aeration pipe 71; the aeration pipe 71 is cleaned by the vertical operation of the sliding cleaning ring 73.

[0152] Specifically, such as Figures 14-16 As shown; the sliding cleaning ring 73 is a ring body, and brush bristles or brush cloth that fit the aeration pipe 71 are provided on the inner side of the ring body; at the same time, each sliding cleaning ring 73 is connected to the other by a fixing rod, and a connecting part is provided at both ends of the ring body to be connected to the power telescopic rod provided on the inner wall of the pool.

[0153] It should be noted that the power telescopic rod of the sliding cleaning ring 73 operates vertically.

[0154] In some embodiments, the aeration zone 2 and the flocculation zone 3 are separated by a baffle 31 that is below the water surface.

[0155] like Figure 14 , 15 As shown, the aerated water flows into the flocculation zone 3 from above the baffle 31.

[0156] In some embodiments, the flocculation zone 3 is provided with a multi-stage inclined filter screen 8, a scoop 81 that cooperates with the inclined filter screen 8, and a suction pipe 822 that cooperates with the scoop 81.

[0157] It should be noted that the high end of the inclined filter screen 8 should be higher than the water surface.

[0158] Correspondingly, the diameter of the sieve holes of the inclined filter screen 8 gradually decreases from left to right; the flocculent material is blocked by the inclined filter screen 8 and adheres to the inclined filter screen 8; the scoop 81 moves upward against the inclined filter screen 8 to scoop out the flocculent material; then, it is sucked away by the suction pipe 822 for processing.

[0159] Among them, the inclined filter screen 8 is inclined downward at the end near the aeration zone 2, and each inclined filter screen 8 is arranged in parallel.

[0160] Specifically, the lower end of the leftmost inclined filter screen 8 is connected to the baffle 31, and the lower ends of the remaining inclined filters screens 8 extend to the left and are connected to the lower ends of the inclined filters screens 8 on their left side by a sealing plate 80.

[0161] In some embodiments, the scoop 81 includes: a second inclined plate 811 that is attached to the inclined filter screen 8, a side plate 812 that is attached to the structure on its left side, a second arc plate 813 that connects the second inclined plate 811 and the side plate 812, and an end plate 814 that closes both ends of the scoop 81; the various plates form a scoop-shaped structure.

[0162] It should be noted that screen holes may be optionally provided on each panel of the scoop 81; however, the screen holes should be smaller than the filter holes of the corresponding inclined filter screen 8.

[0163] In the specific structure:

[0164] like Figures 11-21 As shown in Figure 22; the side plate 812 of the hopper 81 adapted to the leftmost inclined filter screen 8 is a vertical plate that fits against the baffle 31.

[0165] like Figures 11-21 As shown in Figure 23; in the hopper 81 of other inclined filter screens 8, its side plate 812 is a first plate that is attached to the sealing plate 80, and a second plate that is attached to the inclined filter screen 8 on its left side; the connecting part of the first plate and the second plate is set as an arc plate structure.

[0166] like Figures 17-23 As shown, in addition to the first scoop 81, the other scoops 81 can also clean the inclined filter screen 8 on its left side.

[0167] It should be noted that the side plate 812 that is attached to the previous inclined filter 8 does not need to be too large.

[0168] In addition, the scoop bucket 81 is driven by a power telescopic rod arranged parallel to the inclined filter screen 8.

[0169] The path of the telescopic rod is parallel to the inclined filter screen 8; during the movement, the second inclined plate 811 always fits against the inclined filter screen 8.

[0170] In some embodiments, the suction pipe 82 includes: a main suction pipe 821 arranged along the width of the pool, and a plurality of thin branch pipes 822 connected to the main suction pipe 821; by providing a plurality of thin branch pipes 82, the scooping bucket 81 is fully covered.

[0171] Among them, the thin branch tube 82 can be either a flexible tube or a rigid tube.

[0172] During use, when the scoop bucket 81 moves to the cleaning position via the power telescopic rod, the lower end of the thin branch pipe 822 approaches the inner bottom surface of the scoop bucket 81 and sucks away the flocculent material.

[0173] In some embodiments, the right side of the last inclined filter screen 8 is the water outlet zone 4.

[0174] Among them, water outlet 41 is also provided in the water outlet area 4, which is opened on the pool body.

[0175] In some embodiments, a bottom sludge discharge assembly 9 is provided at the bottom of the water outlet zone 4 to further discharge sediments from the water after the previous treatment.

[0176] Specifically, such as Figure 24As shown; the bottom sludge discharge assembly 9 includes: a corrugated bottom plate 91 disposed at the bottom of the water outlet zone 4, and a sludge suction pipe 92 disposed below the corrugated bottom plate 91; correspondingly, the sludge suction pipe 92 is connected to the trough of the corrugated bottom plate 91 through an opening.

[0177] Understandably, under the influence of gravity, more sediment falls into the troughs and is sucked away by the sewage pipe 92.

[0178] When this device is in use, the wastewater to be treated is transported to the top of the inlet filter 5. When passing through the inlet filter 5, large impurities are blocked and propelled by the deflector 55, and led out from the slag discharge port 51. The pre-filtered water flows from the left side to the bottom of the sedimentation zone 1 under the guidance of the guide plate 56 and completes the sedimentation treatment in the sedimentation zone 1. Afterwards, it enters the aeration zone 2 through the adjusted height plate 12 and forms a water flow from top to bottom under the action of the bottom flow guide plate 21, and is fully aerated. Afterwards, it enters the flocculation zone 3, where flocs are generated under the action of chemicals and are discharged. Afterwards, it is pumped out again in the effluent zone 4 and discharged from the effluent port 41.

[0179] When the device needs cleaning, the brush rod 57 is driven by the belt 58 to clean the inner wall of the guide plate 56; the scraper assembly 64 operates to scrape the first inclined plate 61; the sliding cleaning ring 73 rises and falls vertically to clean the aeration pipe 71; the scoop 81 rises and the suction pipe 82 sucks away the flocculent material; and each cleaning structure can be set to timed operation, remote control, etc., without the need for manual on-site operation.

[0180] In this invention, each work area works together to achieve reliable and effective water treatment operations; at the same time, multiple self-cleaning components are set up to maintain the overall good operating condition; and the cleaning operation does not require manual intervention, thus achieving automation and intelligence.

[0181] In this invention, the inlet filter 5 filters the incoming water, preventing large debris from entering the pool and affecting subsequent processes, thus facilitating subsequent treatment operations; the inclined guide plate 52 better guides the discharge of debris and controls the discharge position; the baffle plate 53 prevents water from flowing out from the left side during filtration; the rubber strip 54 provides a better water-blocking effect; the dial wheel 55 smoothly pushes out debris, preventing accumulation and blockage; the guide plate 56 guides the incoming water falling from a height, reducing the direct impact and disturbance of the water in the sedimentation zone 1; the brush rod 57 cleans the guide plate 56; the height adjustment plate 12 works with the overflow plate 11 to adjust the overflow height; a debris extraction component 6 is installed at the bottom of the sedimentation zone 1 to extract the sediment; the first inclined plate 61 works with the settling trough 62 to form... The system achieves a central convergence state, significantly reducing the disturbance range during impurity removal. A scraper assembly 64 cleans the first inclined plate 61 and pushes the attached material towards the central settling trough 62. A bottom flow guide plate 21 is installed in the aeration zone 2 to allow water to flow from bottom to top for better aeration. The arrayed, vertically arranged aeration pipes 71 can fully cover different depths of the entire water zone. Furthermore, in the vertical setting state, the aeration pipes 71 themselves are less contaminated and attached. A sliding cleaning ring 73 is fitted to clean the aeration pipes 71. A multi-stage inclined filter screen 8, along with a scoop bucket 81 and a suction pipe 82, is installed to scoop out and remove flocculent material. The wavy bottom plate 91 structure at the bottom of the outlet zone 4 allows more sediment to fall into the troughs and be sucked away by the sludge suction pipe 92.
