[0002] In today's society, sewage treatment is becoming increasingly important. With the acceleration of industrialization and the continued growth of the population, the amount of sewage generated has increased dramatically. The sources of sewage are diverse, including wastewater generated in industrial production processes, such as chemical, electroplating, printing and dyeing industries. Its composition is complex and often contains large amounts of heavy metals, organic matter and toxic and hazardous substances. Domestic sewage includes sewage containing nutrients such as nitrogen and phosphorus and suspended solids discharged by residents in their daily lives, as well as agricultural sewage containing pollutants such as pesticides and fertilizer residues. If these sewages are discharged directly without effective treatment, they will cause serious damage to the water ecological environment, threaten water resource security, and affect human health and the balance and stability of the ecosystem.

[0003] The prior art (Announcement No.: CN110540323A) discloses a multi-stage sewage treatment device, which includes a shell, a diversion mechanism, a waste lint removal mechanism, a purifier adding mechanism and a multi-stage filtering mechanism, wherein the diversion mechanism is arranged at the top of the inner wall of the shell, the number of the waste lint removal mechanisms is two and both are arranged in the shell, the purifier adding mechanism is arranged on the left side of the shell, and the multi-stage filtering mechanism is arranged on the right side of the bottom of the inner wall of the shell, and a water adding cylinder connected to the top of the inner wall of the shell and corresponding to the position of the diversion mechanism is provided, and pads are fixedly connected to the left and right sides of the inner wall of the shell and located below the diversion mechanism, and grid plates are provided on the tops of the two pads.

[0018] Beneficial effects: The control motor in the cleaning mechanism drives the pulley and screw, driving the oblique scraper to move back and forth along the surface of the filter plate. When moving left, the arc-shaped slide and the slider work together to pull the scraper downward to press the filter plate. The spring 1 helps maintain the contact force, effectively scraping off the accumulated large particles of impurities. When the scraper moves to the left side of the filter plate, the fixed plate squeezes the piston plate, triggering the L-shaped sealing slide to move left to open the oblique flow slot 1. The impurities slide through the oblique guide plate to the collection box, realizing full process automation. There is no need for manual cleaning of the filter plate, completely eliminating the safety hazards and frequency costs of manual cleaning.

[0019] The arc-shaped track design of the arc-shaped chute and the slider enables the oblique scraper to automatically move downward close to the surface of the filter plate during the left-moving scraping stage, effectively removing even adherent impurities. When moving right to reset, the slider slides upward along the arc-shaped groove, and the oblique scraper automatically rises, avoiding damage caused by long-term hard contact with the filter plate. This ensures that the spring of the oblique scraper is always in a reasonable stress state when it is in the initial position, thereby improving cleaning efficiency, reducing the wear rate of the filter plate, and ensuring long-term unobstructed filtration channels.

[0020] The diversion mechanism evenly distributes the sewage to the filter plate to avoid local accumulation of impurities and overload. The cleaning mechanism and the collection system operate in conjunction with each other, and the scraped impurities are directly introduced into the collection chamber without cross-interference with the subsequent treatment process. The multi-stage filtration mechanism simultaneously deeply purifies the supernatant, thus solving the problem of filter plate clogging and improving the overall sewage treatment efficiency.

[0021] By opening the bolts above the sealing cover and releasing the fixation between the connecting pipe and the L-shaped delivery pipe, the sealing cover can be removed, making it easier for staff to regularly replace the filter layer, thereby further improving the efficiency of the device in sewage treatment.

DETAILED DESCRIPTION

[0030] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example

[0032] like Figure 1 As shown, a plurality of supporting legs 8 are fixedly connected to the lower surface of the base plate 1;

[0033] The multiple support legs 8 are provided to achieve stable support for the device, enhance the adaptability of the device in complex environments, ensure the levelness and stability of the equipment during operation, and avoid affecting the sewage treatment effect and equipment life due to support problems.

[0034] like Figure 1 , pictures and Figure 3 As shown, a multi-stage sewage automatic control treatment device is provided, comprising a base plate 1, a disposal box 2 is fixedly connected to the upper surface of the base plate 1, a diversion mechanism 3 is provided above the interior of the disposal box 2, a cleaning mechanism 4 is provided inside the disposal box 2 and below the diversion mechanism 3, and a multi-stage filtering mechanism 5 is fixedly connected to the upper surface of the base plate 1 and located on the right side of the disposal box 2;

[0035] A fixing frame 6 is fixedly connected to the interior of the disposal box 2 and below the cleaning mechanism 4. A filter plate 7 is detachably mounted on the inner side wall of the fixing frame 6.

[0036] The diversion mechanism 3 includes a diversion box 301, the upper surface of which is fixedly connected to the inner upper surface of the disposal box 2, a plurality of diversion pipes 302 are provided on the inner lower surface of the diversion box 301, and an L-shaped water inlet pipe 303 is fixedly connected to the inner upper surface of the diversion box 301;

[0037] The sewage flows into the diversion box 301 through the L-shaped water inlet pipe 303, and is evenly dispersed into the disposal box 2 through the diversion pipe 302. After preliminary distribution by the diversion mechanism 3, the sewage falls to the top of the filter plate 7, and is then filtered through the set filter plate 7. The fixed frame 6 can easily disassemble the filter plate 7 for cleaning and maintenance. The filtered sewage is allowed to settle below the disposal box 2 and then flows into the multi-stage filtration mechanism 5 on the right for further deep treatment. The large particles of impurities above the filter plate 7 can be scraped off by the cleaning mechanism 4 to facilitate the subsequent circulation of sewage. The coordinated design of diversion, filtration, cleaning and multi-stage treatment can achieve efficient purification of sewage, which not only evenly distributes sewage to improve treatment efficiency, but also facilitates maintenance of the filter components. At the same time, multi-stage filtration ensures the water quality of the effluent and adapts to the automated treatment needs of different sewage.

[0038] like Figure 1-Figure 5 As shown, the cleaning mechanism 4 includes a movable plate 401, a screw rod 402 is symmetrically connected to the left side of the disposal box 2, and the outer walls of the two screw rods 402 are commonly threadedly connected to a fixed plate 403. The lower surface of the fixed plate 403 is fixedly connected to the upper surface of the movable plate 401. A through-type extension groove 404 is opened on the inner lower surface of the movable plate 401. A movable plate 405 is slidably connected to the inside of the movable plate 401. The lower surface of the movable plate 405 is fixedly connected to an oblique scraper 406. The bottom end of the oblique scraper 406 passes through the extension groove 404. The inner upper surface of the movable plate 401 and the upper surface of the movable plate 405 are fixedly connected with a plurality of springs 407.

[0039] A pulley 1 408 is rotatably connected to the upper right side of the disposal box 2. The right ends of the two screws 402 extend to the right side of the disposal box 2 and are fixedly connected to a pulley 2 409. The outer wall of the pulley 1 408 and the outer wall of the pulley 2 409 are jointly connected to a transmission belt 410. The right side of the pulley 1 408 is fixedly connected to a control motor 411. The right side of the control motor 411 is fixedly connected to the right side of the disposal box 2.

[0040] By controlling the motor 411 to drive the pulley 1 408 to rotate, the transmission belt 410 drives the two pulleys 2 409 to rotate synchronously, so that the screw 402 rotates and drives the fixed plate 403 and the movable plate 401 to move horizontally along the disposal box 2. At this time, the movable plate 405 slides in the movable plate 401, and the bottom end of the oblique scraper 406 is close to the surface of the filter plate 7. The spring 1 407 maintains the fitting force between the oblique scraper 406 and the filter plate 7, and the large particles of impurities above the filter plate 7 are scraped to the left side of the disposal box 2. The oblique scraper 406 is automatically reciprocated by driving the screw 402 through the control motor 411. At the same time, the spring 1 407 buffer structure can ensure the scraping effect and prevent the filter plate 7 from being damaged. It can effectively remove impurities on the surface of the filter plate 7, maintain the filtration efficiency, reduce the frequency of manual cleaning, and improve the automatic operation capability of the device.

[0041] like Figure 1-Figure 4 As shown, a purifier storage box 9 is fixedly connected to the right side of the disposal box 2, and a dropper 10 is fixedly connected to the left end of the purifier storage box 9. The left end of the dropper 10 extends to the bottom of the fixed frame 6. An L-shaped delivery pipe 11 is provided on the right side of the interior of the disposal box 2 and below the dropper 10. The right end of the L-shaped delivery pipe 11 extends to the outside of the disposal box 2 and is detachably connected to a connecting pipe 12. A sewage pipe 13 is provided at the lower left side of the interior of the disposal box 2.

[0042] The multi-stage filtration mechanism 5 includes a filter box 501. A sealing cover plate 502 is fixedly connected to the upper surface of the filter box 501 by bolts. The lower surface of the sealing cover plate 502 is provided with a filter layer 1 503, a filter layer 2 504, and a filter layer 3 505 from left to right. The bottom end of the connecting pipe 12 is connected to the interior of the filter box 501. A drain pipe 506 is provided at the lower right side of the interior of the filter box 501.

[0043] After the initial filtration of large particles of impurities, the sewage is left to settle at the bottom of the disposal box 2. At this time, the purifier storage box 9 drips purifiers into the sewage below the fixed frame 6 through the dropper 10, which promotes the coagulation and sedimentation of fine impurities. The precipitated sewage flows into the multi-stage filtration mechanism 5 through the L-shaped conveying pipe 11 and the connecting pipe 12, and is filtered through the filter layer 1 503, the filter layer 2 504 and the filter layer 3 505 in turn to remove pollutants of different particle sizes. The purified water is discharged through the drain pipe 506, and the sediment in the disposal box 2 is discharged through the left sewage pipe 13. Through the synergistic effect of purifier-assisted precipitation and multi-stage filtration, the purifier can be used to accelerate the coagulation of impurities and improve the sedimentation efficiency, and the pollutants can be deeply removed through the multi-layer filter material to ensure the water quality of the effluent. At the same time, the sewage pipe 13 and the drain pipe 506 are independently arranged to avoid sediment blocking the filter channel, thereby achieving efficient and sustainable sewage purification.

[0044] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown, the left side of the disposal box 2 is fixedly connected to the fixed box 14, and a control chamber 15 is integrally formed on the upper part of the interior of the fixed box 14. A through-type oblique circulation groove 16 is provided on the upper surface of the fixed frame 6 and located on the left side of the filter plate 7. A slot 28 is provided on the right side of the interior of the oblique circulation groove 16. A through-type movable groove 17 is provided on the left side of the interior of the oblique circulation groove 16 and the left side of the interior of the control chamber 15. An L-shaped sealing slide 18 is slidably connected to the lower surface of the interior of the control chamber 15. The right side of the L-shaped sealing slide 18 passes through the movable groove 17 and extends to the inside of the slot 28. A through-type movable groove 2 19 is provided on the left side of the interior of the disposal box 2 and located above the oblique circulation groove 16. A piston plate 20 is fixedly connected to the right side of the L-shaped sealing slide 18. The right side of the piston plate 20 passes through the movable groove 2 19. A plurality of springs 21 are fixedly connected to the left side of the L-shaped sealing slide 18 and the left side of the interior of the control chamber 15.

[0045] A collecting chamber 22 is integrally formed at the lower interior of the fixed box 14. A collecting box 23 is provided on the lower interior surface of the collecting chamber 22. A pull plate 24 is fixedly connected to the front surface of the collecting box 23. The front surface of the pull plate 24 extends to the front of the fixed box 14. A through-type oblique flow slot 25 is provided on the right interior side of the collecting chamber 22 and the left interior side of the disposal box 2. An oblique material guide plate 26 is fixedly connected to the lower surface of the fixed frame 6 and the left interior side of the collecting chamber 22.

[0046] When the oblique scraper 406 moves to the left with the movable plate 401, the fixed plate 403 will squeeze the piston plate 20, causing it to move to the left and drive the L-shaped sealing slide plate 18 to overcome the elastic force of the spring 21 and move to the left synchronously. After the L-shaped sealing slide plate 18 disengages from the slot 28, the channel of the oblique flow groove 16 is opened. At this time, the large particles of impurities scraped by the oblique scraper 406 pass through the oblique flow groove 16 and the oblique flow groove 2, 25, and slide into the collection box 23 in the collection chamber 22 under the guidance of the oblique guide plate 26, thereby realizing automatic control of impurity collection without the need for an additional power source. When the oblique scraper 406 moves into place, the channel is automatically opened, and the impurity collection is completed by gravity guidance. The spring 21 can make the L-shaped sealing slide plate 18 reset the seal after the extrusion is completed to prevent sewage leakage. The collection box 23 can be easily taken out and cleaned through the pull plate 24, which not only avoids the accumulation of impurities affecting the filtration efficiency, but also realizes the integrated automatic operation of scraping and collection, thereby improving the practicality and convenience of the device.

[0047] like Figure 6 As shown, the inner left side and the inner right side of the control chamber 15 are fixedly connected to a plurality of guide rods 27, and the outer side walls of the plurality of guide rods 27 are slidably connected to the inner side of the L-shaped sealing slide 18;

[0048] By setting up multiple guide rods 27 and slidingly cooperating with the L-shaped sealing slide 18, guide support is provided for the left and right movement of the L-shaped sealing slide 18, ensuring that the L-shaped sealing slide 18 can slide smoothly along the guide rods 27 when the piston plate 20 is squeezed or the spring 21 is reset, avoiding deviation or jamming, thereby ensuring the accuracy and reliability of opening and closing of the oblique flow groove 16 channel, and at the same time enhancing the stability of the L-shaped sealing slide 18 during movement and extending the service life of the component.

[0049] like Figure 3 and Figure 4 As shown, the inner front surface and the inner rear surface of the disposal box 2 are both provided with arc-shaped slide grooves 412, and the interiors of the two arc-shaped slide grooves 412 are slidably connected to sliders 413, and the opposite sides of the two sliders 413 are fixedly connected to U-shaped plates 414, and the sides of the two U-shaped plates 414 away from the two sliders 413 pass through the extension groove 404 and are fixedly connected to the lower surface of the movable plate 405;

[0050] When the inclined scraper 406 is reset to the right, the slider 413 slides upward along the arc slot 412, driving the inclined scraper 406 to rise, thereby separating from the surface of the filter plate 7, and at this time, the spring 1 407 returns to its natural state of not being stretched or compressed, avoiding elastic attenuation caused by long-term force, thereby realizing that the inclined scraper 406 adjusts its contact force with the filter plate 7 along the moving trajectory, enhancing the scraping effect when moving left, and releasing the pressure of the spring 1 407 when resetting, which not only ensures the impurity cleaning efficiency, but also extends the service life of the spring 1 407 and reduces maintenance costs.

[0051] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
