Description

Technical Field

[0001] The present application relates to the field of sewage treatment equipment, and in particular to a sewage sedimentation and drainage tank. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. Sedimentation tanks are commonly used equipment in sewage treatment. Sedimentation tanks are a structure that uses sedimentation to remove suspended matter in water. Sedimentation tanks are widely used in wastewater treatment.

[0003] Sedimentation tanks are generally structures for separating mud and water before or after biochemical treatment, and are mostly used to separate sludge with finer particles. During use, the sludge in the sedimentation tank needs to be discharged from the sedimentation tank. The sewage discharge device in the prior art usually installs a valve at the bottom of the sewage tank. The bottom surface of the sewage tank is a conical structure, and the sediment is squeezed out of the valve by the pressure of the sewage. When the conical slope of the bottom of the sewage tank is large, the area of ​​the sewage tank will be smaller; when the conical slope of the bottom of the sewage tank is small, the sludge at the bottom of the sewage tank will adhere to the bottom and will not flow with the sewage discharge process, and the sewage discharge effect needs to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present application provides a sewage sedimentation and drainage tank.

[0005] The sewage sedimentation and drainage tank provided in this application adopts the following technical solution:

[0006] A sewage sedimentation and drainage tank comprises a tank body, which has a rectangular structure. The bottom of the tank body is a sloped surface with a central depression. A drainage pipe connecting the inside and outside of the tank body is arranged at the center of the bottom of the tank body, and a valve is arranged on the drainage pipe. Two fixing rods are fixedly arranged on one side wall of the tank body, and a diverter plate is hinged at the end of the fixing rod. A support rod is fixedly arranged on the diverter plate. When the diverter plate is in a horizontal state, the support rod supports the bottom of the tank body, and gaps are left between the four sides of the diverter plate and the corresponding side surfaces of the tank body.

[0007] A further technical solution is that an operating rod is hinged on the side plate of the diverter plate, and a first clamping plate for fixing the operating rod is fixedly provided on the side edge of the diverter plate.

[0008] A further technical solution is that a second clamping plate for fixing the operating rod is fixedly provided on the inner side surface of the pool body, and the openings of the first clamping plate and the second clamping plate face opposite directions.

[0009] This application has the following beneficial technical effects:

[0010] By setting a guide plate in the tank body, when discharging the sludge at the bottom of the tank, the diverter plate can be rotated to a horizontal state. After the valve is opened, the sludge near the valve is discharged, and the sewage pressure in the tank body is applied to the sludge at the bottom of the tank body away from the sewage pipe through the four sides of the diverter plate. As a result, the sludge around the bottom can be pressed as a whole to the center of the tank body under the pressure of the water flow and discharged, thereby effectively improving the sewage discharge effect of the sewage sedimentation tank.

[0014] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0015] The present application embodiment discloses a sewage sedimentation and drainage tank. Figure 1 and Figure 2 A sewage sedimentation and drainage tank comprises a tank body 1, which is in a rectangular structure. The bottom of the tank body 1 is a sloped surface with a central depression. A sewage pipe 2 connecting the inside and outside of the tank body 1 is arranged at the bottom center of the tank body 1, and a valve 3 is arranged on the sewage pipe 2; two fixing rods 4 are fixedly arranged on one side wall of the tank body 1, and a diverter plate 5 is hinged at the end of the fixing rod 4, and a support rod is fixedly arranged on the diverter plate 5. When the diverter plate 5 is in a horizontal state, the support rod is supported on the bottom of the tank body 1, and gaps are left between the four sides of the diverter plate 5 and the corresponding side surfaces of the tank body 1.

[0016] After the sludge in the tank body 1 settles, it falls to the bottom of the tank body 1. When the sludge at the bottom of the tank needs to be discharged, the diverter plate 5 can be rotated to a horizontal state, and the support rod on the diverter plate 5 is supported at the bottom of the tank body 1. At this time, the valve 3 is opened, and the sludge near the valve 3 is discharged. The sewage pressure in the tank body 1 is applied to the sludge at the bottom of the tank body 1 away from the sewage pipe 2 through the surrounding of the diverter plate 5, so that the sludge at the bottom can be pressed as a whole to the center of the tank body 1 under the pressure of the water flow and discharged, thereby effectively improving the sewage discharge effect of the sewage sedimentation tank.

[0017] Furthermore, the side plate of the diverter plate 5 is hinged with an operating rod 6, and the side edge of the diverter plate 5 is fixedly provided with a first clamping plate 7 for fixing the operating rod 6; the inner side surface of the pool body 1 is fixedly provided with a second clamping plate 8 for fixing the operating rod 6, and the openings of the first clamping plate 7 and the second clamping plate 8 are facing opposite directions.

[0018] Open the operating lever 6, and the operator can hold the operating lever 6 to lay flat and pull up the guide plate. When the guide plate is pulled up, the guide plate is parallel to the side wall of the pool body 1. At this time, the pool body 1 can undergo a sedimentation reaction, and the operating lever 6 is clamped on the first clamping plate 7 and the second clamping plate 8 to fix the guide plate.

[0019] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
