[0038] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figure 1 - Figure 8 The pulverized carbon and sand high-efficiency sedimentation tank comprises a sedimentation tank body 1. A first partition plate 2 and a second partition plate 3 are fixedly mounted on the inner side wall of the sedimentation tank body 1. The first partition plate 2 and the second partition plate 3 divide the sedimentation tank body 1 into three independent chambers, one for the coagulation zone 4, one for the flocculation zone 5, and the other for the clarification zone 6.

[0040] The inner wall of the sedimentation tank body 1 is fixedly mounted with a fixing frame 7, and the fixing frame 7 is located inside the clarification zone 6. The inner wall of the fixing frame 7 is fixedly mounted with an inclined pipe 8.

[0041] A water collecting shell 9 for collecting clarified water is fixedly installed on one side of the sedimentation tank body 1, and a sewage discharge assembly 11 for discharging sludge in the sedimentation tank body 1 is provided below the water collecting shell 9;

[0042] A guide pipe 10 is provided in the direction groove connecting the fixing frame 7 and the sedimentation tank body 1, and the guide pipe 10 is fixedly installed on the sedimentation tank body 1;

[0043] Two lifting assemblies 12 are provided on the sedimentation tank body 1. A mounting plate 13 is fixedly connected to the two lifting assemblies 12. A first stirring assembly 14, a second stirring assembly 15 and a sludge scraping assembly 16 are respectively provided on the mounting plate 13.

[0044] A first feeding pipe 17 and a second feeding pipe 18 are respectively installed through the mounting plate 13, and the bottom of the first feeding pipe 17 is located inside the coagulation zone 4, and the bottom of the second feeding pipe 18 is located inside the flocculation zone 5;

[0045] Two hinge frames 19 are fixedly mounted on the top of the two mounting plates 13 . A hinge plate 20 is hingedly mounted on the inner side of the hinge frame 19 , and one end of the hinge plate 20 is fixedly connected to the mounting plate 13 .

[0046] The pulverized carbon and sand high-efficiency sedimentation tank provided by the utility model, when in use, the sewage and the coagulant can enter the coagulation zone 4 inside the sedimentation tank body 1 through the water inlet pipe on one side of the sedimentation tank body 1 and the first feeding pipe 17 on the mounting plate 13, and then the first stirring component 14 is controlled by an external controller to stir the sewage in the coagulation zone 4, so that the sewage and the coagulant can be quickly mixed, and then the coagulated water can enter the flocculation zone 5 through the gap at the bottom of the first partition 2, and then the flocculant is introduced into the flocculation zone 5 through the second feeding pipe 18, and at the same time, it is stirred by the second stirring component 15, so that the coagulated water can be quickly flocculated, and then the flocculated water is allowed to enter the clarifying zone 6 through the gap between the second partition 3 and the fixing frame 7. After the flocs are enlarged and dense, they will quickly settle to the bottom of the tank, and at the same time, the clarified water rises through the inclined pipe 8, and then passes through the guide pipe 10, so that the clarified water can enter the water collecting shell 9 and flow to the next treatment through the outlet pipe at the bottom of the water collecting shell 9. The sludge at the bottom of the sedimentation tank body 1 is discharged into the sludge storage tank through the sewage discharge component 11. At the same time, the sludge at the bottom of the sedimentation tank body 1 can be scraped by the sludge scraping component 16, thereby preventing the sludge near the second partition 3 from being sucked and discharged by the sewage discharge component 11. Finally, the lifting component 12 is controlled by the external controller to drive the mounting plate 13 to rise. At the same time, under the action of the articulated frame 19 and the articulated plate 20, the mounting plate 13 on the lifting component 12 has space for angle adjustment when rising, thereby preventing the screws on the two lifting components 12 from having different pitches, making it difficult or impossible for the mounting plate 13 to rise. Then the rising mounting plate 13 drives the first stirring component 14, the second stirring component 15 and the sludge scraping component 16 thereon to rise from the sedimentation tank body 1, thereby facilitating cleaning by personnel, thereby reducing the labor intensity required for cleaning personnel to enter the sedimentation tank for cleaning and climb out of the sedimentation tank.

[0048] Specifically, the threaded rod 1202 is driven to rotate by the first motor 1205, and then the rotating threaded rod 1202 drives the connecting block 1203 threadedly connected thereto, and with the cooperation of the limiting rod and the connecting block 1203 on the limiting rod, it can stably drive the second U-shaped frame 1204 to rise, so that the first stirring assembly 14, the second stirring assembly 15 and the mud scraping assembly 16 can be lifted from the sedimentation tank body 1, so that personnel do not need to go down into the sedimentation tank when cleaning, which effectively reduces the labor intensity and time consumption of the cleaning personnel.

[0049] Furthermore, anti-rotation baffles 21 are fixedly installed on both sides of the inner wall of the sedimentation tank body 1, and the anti-rotation baffles 21 are located on the inner side of the flocculation zone 5. An inlet guide tube 23 is provided in the middle of the two anti-rotation baffles 21, and the other sides of the two anti-rotation baffles 21 are fixedly connected to the water inlet guide tube 23, and the bottom of the second stirring assembly 15 is set to the inner side of the water inlet guide tube 23.

[0052] Specifically, the second motor 1401 drives the connecting rod 1402 to rotate, so that the axial flow impeller 1403 can stir the sewage in the coagulation zone 4.

[0053] It should also be noted that since the structure of the second stirring component 15 is the same as that of the first stirring component 14, no further description will be given.

[0054] Furthermore, the scraper assembly 16 includes a third motor 1601 fixedly mounted on the top of the mounting plate 13, a rotating rod 1602 is provided through the mounting plate 13, and the rotating rod 1602 is rotatably connected to the mounting plate 13, the output end of the third motor 1601 is fixedly connected to the rotating rod 1602, and two connecting frames 1603 are symmetrically fixedly mounted on the outer wall of the rotating rod 1602, a pair of scrapers 1604 are fixedly mounted at the bottom of the two connecting frames 1603, and the connecting frames 1603 are located on the inner side of the clarification area 6.

[0055] Specifically, the third motor 1601 drives the rotating rod 1602 to rotate, and then the rotating rotating rod 1602 synchronously drives the connecting frame 1603, so that the scraper 1604 can scrape the sludge at the bottom of the sedimentation tank body 1, thereby preventing the sludge near the second partition 3 from being sucked in and discharged by the sewage discharge component 11.

[0056] Furthermore, a guide frame 22 is fixedly installed on the inner bottom wall of the sedimentation tank body 1 , and the guide frame 22 is located inside the clarification zone 6 , and the rotating rod 1602 is located inside the guide frame 22 .

[0057] Specifically, the guide frame 22 is used to prevent sludge from accumulating at the corners in the clarification zone 6 .

[0059] Specifically, the sludge deposited in the sedimentation tank body 1 is extracted through the sludge pump 1101 , the connecting pipe 1102 , the three-way joint and the extraction pipe 1103 , and then the sludge is discharged into the sludge storage tank through the sewage pipe 1104 .

[0060] It should also be noted that the length of the sewage pipe 1104 can be lengthened according to actual conditions and needs to avoid the sewage pipe 1104 being too short and unable to be connected to the mud storage tank.
