Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a municipal sewage sedimentation tank. Background Art

[0002] Sedimentation tank is a kind of water purification structure, which uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter in water. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow.

[0003] Vertical sedimentation tanks are commonly used for municipal sewage treatment. During the use of vertical sedimentation tanks, a large amount of sludge and other debris will settle at the bottom. Since the vertical sedimentation tank is deep, the water in the sedimentation tank needs to be pumped out first when cleaning, and then the workers go down to the bottom of the sedimentation tank to clean it. There are problems such as high labor intensity, high risk, and low cleaning efficiency. In order to deal with the above technical problems, a municipal sewage sedimentation tank is proposed.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A municipal sewage sedimentation tank comprises a tank body 1, on which a sedimentation tank 2 and a water storage tank 3 are arranged through a partition. Figure 1 As shown, the pool body 1 is U-shaped.

[0022] A filter assembly 4 is installed on the partition, a lifting screw 7 is provided on the pool body 1 through a driving motor 6, a lifting plate 8 is provided on the lifting screw 7 through a nut, two moving ports 10 are provided on the lifting plate 8, a double-headed screw 18 is provided in both the two moving ports 10, a rack 14 is provided on the pool body 1, the double-headed screw 18 is connected to the rack 14 through a rotating mechanism, a connecting plate 11 threadedly sleeved on the double-headed screw 18 is provided in both the moving ports 10, a lifting plate 12 is provided in the sedimentation tank 2 for sealing and sliding, and the lifting plate 12 is connected to the connecting plate 11 through a connecting mechanism.

[0023] The rotating mechanism includes a gear 17 arranged on the outside of the lifting plate 8. The gear 17 is connected to the double-headed screw 18 through a connecting shaft. The gear 17 is meshed with the rack 14. When the lifting plate 8 rises to a certain height, it will drive the gear 17 to mesh with the rack 14. Conversely, when it falls to a certain height, the gear 17 will lose the meshing state with the rack 14.

[0024] The connecting mechanism includes a connecting groove 16 arranged on the bottom wall of the lifting plate 12, and the bottom wall of the pool body 1 is provided with a movable opening 15 corresponding to the connecting plate 11. The connecting groove 16 and the connecting plate 11 are both L-shaped in vertical section. The movable opening 15 adapts to the horizontal and vertical movement of the connecting plate 11. The above-mentioned L-shaped structure can only be separated from the connecting groove 16 after the horizontal part of the connecting plate 11 moves to a certain position in the connecting groove 16.

[0025] The filter assembly 4 is installed on the pool body 1 by means of a bolt assembly. Both the filter assembly 4 and the lifting plate 12 are provided with a lifting handle 13. With the help of the lifting handle 13, the filter assembly 4 and the lifting plate 12 can be lifted and disassembled after losing the fixed connection.

[0026] A vertical rod 9 is provided on the pool body 1, and the vertical rod 9 is parallel to the lifting screw 7. The vertical rod 9 slides through the lifting plate 8. A cross bar 19 is provided in the moving port 10, and the cross bar 19 is parallel to the double-headed screw 18. The cross bar 19 slides through the connecting plate 11. The above-mentioned cross bar 19 and vertical rod 9 respectively realize the limiting of the connecting plate 11 and the lifting plate 8, thereby preventing the above-mentioned components from rotating together with the double-headed screw 18 and the lifting screw 7 respectively.

[0027] When the utility model is used, sewage enters the sedimentation tank 2 on the pool body 1 for sedimentation operation. When the sedimentation is completed, the driving motor 6 is started, and the driving motor 6 drives the lifting screw 7 to rotate. When the lifting screw 7 rotates, the nut on the outer wall drives the lifting plate 8 to rise. The lifting plate 8 drives the lifting plate 12 to rise in the sedimentation tank 2 with the help of the connecting plate 11, so that the sewage and sludge are raised, and the inner wall of the sedimentation tank 2 can be scraped and cleaned during the rising process of the lifting plate 12.

[0028] As the lifting plate 12 rises, the sewage will eventually pass through the filter assembly 4 and enter the water storage tank 3, realizing the separation of sludge and the like from water. In the above-mentioned rising process, the gear 17 will mesh with the rack 14 and drive the double-headed screw 18 to rotate. When the double-headed screw 18 rotates, the connecting plate 11 will move and finally complete the separation operation from the connecting groove 16. Finally, the lifting plate 12 can be disassembled with the help of the lifting handle 13. Disassembly makes it easier to clean the sludge and the like and thoroughly clean the lifting plate 12.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
