The sedimentation tank for environmental water treatment is provided with a threaded rod, a threaded block, a rectangular frame and a cleaning knife. When the inner wall of the water tank needs to be cleaned, the threaded rod is rotated. When the threaded rod is rotated, the threaded block connected to the outer side of the threaded rod is driven to move up and down. When the threaded block moves up and down, the rectangular frame is driven to move up and down. When the rectangular frame moves up and down, the cleaning knife is driven to clean the inner wall of the water tank up and down, thereby realizing the problem of cleaning the inner wall of the water tank.

[0004] The above-mentioned environmental protection water treatment sedimentation tank still has the following shortcomings:

[0005] Although the above-mentioned sedimentation tank for environmental protection water treatment moves up and down through the rectangular frame to drive the cleaning knife to sweep the inner wall of the pool up and down, thereby realizing the cleaning of the inner wall of the pool, but because the rectangular frame is almost level with the cleaning knife, when there are many impurities scraped on the surface of the cleaning knife, the impurities can easily overflow the rectangular frame and fall back into the inside of the pool from the hollow part in the middle of the rectangular frame, reducing the cleaning effect. In view of this, we propose an energy-saving sedimentation tank for water treatment. Utility Model Content

[0015] 1. The utility model effectively collects the sedimentation flocculants through the collecting bin and the angle between the collecting bin and the special-shaped scraper. Subsequently, the sedimentation flocculants can be centrally transferred and processed only by moving the cleaning mechanism upward and out of the sedimentation tank body. There is no need to use a sludge pump to suck the sedimentation flocculants, thereby reducing energy consumption.

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0025] Energy-saving sedimentation tanks for water treatment, see Figures 1 to 3 , comprising a sedimentation tank body 1, a group of regulating mechanisms 2 are symmetrically arranged on the surface of the sedimentation tank body 1, a cover plate 3 is attached to the top of the sedimentation tank body 1, a slot 4 is opened inside the cover plate 3, a stirring mechanism 5 is arranged at the middle end of the top of the cover plate 3, and a cleaning mechanism 6 is arranged at the bottom of the cover plate 3;

[0026] The cleaning mechanism 6 includes a groove rod 601, which is fixed to the bottom of the cover plate 3. A vertical rod 602 is engaged inside the groove rod 601. The groove rod 601 and the vertical rod 602 are connected by bolts 603. The bottom of the vertical rod 602 is connected to a collecting bin 604. The bottom of the collecting bin 604 is fixed with a special-shaped scraper 605, wherein the inner diameter of the special-shaped scraper 605 gradually decreases from top to bottom, and the top of the special-shaped scraper 605 fits against the inner wall of the sedimentation tank body 1. The utility model effectively collects the sedimentation flocs through the collecting bin 604 and the angle between the collecting bin 604 and the special-shaped scraper 605. Subsequently, the sedimentation flocs can be centrally transferred and processed by only moving the cleaning mechanism 6 upward and out of the sedimentation tank body 1. There is no need to use a mud pump to suck the sedimentation flocs, thereby reducing energy consumption. At the same time, when the cleaning mechanism 6 moves upward, the special-shaped scraper 605 effectively scrapes the inner wall of the sedimentation tank body 1, thereby cleaning the inner wall of the sedimentation tank body 1. The cleaned impurities are affected by the inclination of the inner wall of the special-shaped scraper 605 and accumulate at the angle between the collecting bin 604 and the special-shaped scraper 605.

[0027] It is worth noting that the adjustment mechanism 2 includes a fixed trough frame 201, which is fixed to the surface of the sedimentation tank body 1, and a hydraulic cylinder is arranged inside the fixed trough frame 201. A hydraulic rod 202 is arranged on the top of the hydraulic cylinder, wherein the hydraulic rod 202 is fixedly connected to the cover plate 3, and a group of hydraulic rods 202 are symmetrically arranged. In the utility model, the hydraulic rod 202 effectively drives the cover plate 3 to move up and down, thereby realizing the adjustment of the position of the cleaning mechanism 6 at the bottom of the cover plate 3 in the sedimentation tank body 1.

[0028] It is worth noting that the stirring mechanism 5 includes a motor 501, a shaft 502 is connected to the lower end of the motor 501, and a plurality of stirring rods 503 are distributed on the surface of the shaft 502, wherein the motor 501 forms a rotating structure through the shaft 502 and the stirring rods 503, and the shaft 502 and the stirring rods 503 are fixedly connected. In the utility model, the motor 501 effectively drives the shaft 502 and the stirring rods 503 to rotate, thereby accelerating the mixing of the flocculant and the wastewater, improving the flocculation efficiency, and reducing the flocculation time.

[0029] Working principle: wastewater is injected into the sedimentation tank body 1 through the slot 4, and flocculant is added into the sedimentation tank body 1 through the slot 4, and then the motor 501 is started, and the motor 501 drives the shaft 502 and the stirring rod 503 to rotate, thereby accelerating the mixing of the flocculant and the wastewater. After a period of time, the precipitated floccules are accumulated in the collection bin 604 and at the angle between the collection bin 604 and the special-shaped scraper 605, and the supernatant gradually becomes obvious. The supernatant is observed through the slot 4. When the supernatant is relatively clear, the supernatant is sucked through the external water pipe and the pump. After completion, the cover plate 3 is driven upward by the hydraulic rod 202 until the collecting bin 604 and the special-shaped scraper 605 are moved out of the sedimentation tank body 1. When the cleaning mechanism 6 moves upward, the special-shaped scraper 605 scrapes the inner wall of the sedimentation tank body 1, thereby cleaning the inner wall of the sedimentation tank body 1. The cleaned impurities are affected by the inclination of the inner wall of the special-shaped scraper 605 and accumulate at the angle between the collecting bin 604 and the special-shaped scraper 605. When it is necessary to clean the collecting bin 604 and the special-shaped scraper 605, the collecting bin 604 and the special-shaped scraper 605 can be removed by removing the bolts 603 for easy cleaning.
