Description

Technical Field

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

[0002] Sedimentation tank is a kind of structure that uses sedimentation to remove suspended solids in water. Sedimentation tank is widely used in wastewater treatment. It has many forms. According to the direction of water flow in the tank, it can be divided into three types: horizontal flow type, vertical flow type and radial flow type. The horizontal flow type consists of three parts: inlet and outlet, water flow part and sludge hopper.

[0003] The existing horizontal flow sedimentation tank has a simple structure and can filter large suspended objects through the baffle at the water inlet. However, when the horizontal flow sedimentation tank is in use, when sewage enters the sedimentation tank through the sewage inlet, due to the large drop in height, some of the precipitated impurities will be re-flushed, which reduces the sedimentation efficiency.

[0014] 1. This type of sedimentation tank for sewage treatment has multiple buffer components fixedly installed inside the sewage sedimentation tank. Under the action of multiple stepped buffer components, it can prevent some impurities settled at the bottom of the sewage sedimentation tank from being re-flushed due to excessive drop in height when sewage enters the sewage sedimentation tank through the water inlet, thereby enhancing the sedimentation efficiency of the sewage sedimentation tank.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] See also Figure 1-4 A sedimentation tank for sewage treatment comprises a sewage sedimentation tank 1, wherein a water inlet 2 is formed through one side wall of the sewage sedimentation tank 1, a water outlet 3 is formed through one side wall of the sewage sedimentation tank 1 away from the water inlet 2, a plurality of buffer components 4 are fixedly installed inside the sewage sedimentation tank 1, the plurality of buffer components 4 are arranged in a stepped manner, a cleaning component 6 is movably installed inside the buffer component 4, a filter screen 5 is movably installed outside an arc plate 402 inside the sewage sedimentation tank 1, under the action of the plurality of stepped buffer components 4, part of the impurities precipitated at the bottom of the sewage sedimentation tank 1 can be prevented from being re-flushed due to excessive drop in height when the sewage enters the sewage sedimentation tank 1 through the water inlet 2, thereby enhancing the sedimentation efficiency of the sewage sedimentation tank 1, and the floating impurities with a larger volume inside the sewage can be filtered under the action of the filter screen 5, which can prevent the floating impurities from floating on the upper surface of the sewage sedimentation tank 1.

[0024] Furthermore, if Figure 4 As shown, the buffer component 4 specifically includes a buffer table 401, the cross-section of the buffer table 401 is a trapezoidal setting, and an arc plate 402 is fixedly installed at the lower end of the buffer table 401. When the sewage enters the sewage sedimentation tank 1, it collides with the inclined surface of the buffer table 401 under the action of gravity, and the water flow after the collision with the buffer table 401 accumulates between the buffer table 401 and the arc plate 402. When the water level between the buffer table 401 and the arc plate 402 exceeds the arc plate 402, the sewage will enter the next buffer component 4 or the bottom of the sewage sedimentation tank 1, and the buffer component 4 can slow down the impact of the water flow on the bottom of the sewage sedimentation tank 1.

[0025] Furthermore, if Figure 4 As shown, the cleaning component 6 specifically includes a threaded rod 601, both ends of the threaded rod 601 are rotatably connected to the corresponding positions on the inner wall of the sewage sedimentation tank 1, a cleaning plate 602 is movably installed on the outer wall of the threaded rod 601, the cleaning plate 602 is threadedly connected to the threaded rod 601, and the cleaning plate 602 is matched with the arc plate 402. A handle 603 is movably installed at a position corresponding to one end of the threaded rod 601 on the outer wall of the sewage sedimentation tank 1, and the handle 603 is fixedly connected to the end of the threaded rod 601. The user can rotate the handle 603 externally to make the cleaning plate 602 threadedly connected to the outer wall of the threaded rod 601 move under the action of the threaded transmission, thereby concentrating the gap between the buffer table 401 and the arc plate 402, and finally the user can uniformly process the impurities concentrated in the buffer component 4.

[0026] Furthermore, if Figure 3As shown, ties 8 are fixedly installed at the four corners of the filter screen 5, and fixing rings 7 are fixedly installed at the positions corresponding to the four corners of the filter screen 5 on the inner wall of the sewage sedimentation tank 1, and the ties 8 are movably connected with the fixing rings 7. The filter screen 5 is mainly fixed at the four corners by four ties 8 and the fixing rings 7. The user can also replace the filter screen 5 by separating the ties 8 and the fixing rings 7.

[0027] Furthermore, if Figure 2 As shown, the lower end of the filter screen 5 is not higher than the upper end surface of the arc plate 402. The lower end of the filter screen 5 is located below the upper end surface of the arc plate 402 to ensure the filtering effect of the filter screen 5 on floating garbage on the sewage.

[0028] Working principle: When in use, the sewage that needs to be precipitated enters the sewage sedimentation tank 1 from the water inlet 2. When the sewage enters the sewage sedimentation tank 1, it collides with the inclined surface of the buffer platform 401 under the action of gravity. The water flow after colliding with the buffer platform 401 accumulates between the buffer platform 401 and the curved plate 402. When the water level between the buffer platform 401 and the curved plate 402 exceeds the curved plate 402, the sewage will enter the next buffer component 4 or the bottom of the sewage sedimentation tank 1. Under the action of multiple stepped buffer components 4, it can prevent the sewage from entering the sewage sedimentation tank 1 through the water inlet 2 due to the large drop in the bottom of the sewage sedimentation tank 1. The impurities are flushed out again, thereby enhancing the sedimentation efficiency of the sewage sedimentation tank 1. When the sewage to be precipitated passes through the buffer component 4 and enters the sewage sedimentation tank 1, the floating impurities with a larger volume inside the sewage can be filtered under the action of the filter net 5, which can prevent the floating impurities from floating on the upper surface of the sewage sedimentation tank 1. When the sewage sedimentation tank 1 is not in use, the user can rotate the handle 603 externally to make the cleaning plate 602 threadedly connected to the outer wall of the threaded rod 601 move under the action of the threaded transmission, thereby concentrating the gap between the buffer table 401 and the arc plate 402. Finally, the user can uniformly process the impurities concentrated in the buffer component 4.
