Description

Technical Field

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

[0002] Over the long term, aging sewer systems often face increased wastewater treatment loads and complex water quality changes. To meet the demands of modern urban development, their functionality needs to be optimized and improved. Sedimentation tanks, as a crucial component of wastewater treatment, effectively separate suspended particulate matter through sedimentation, reducing the burden on subsequent treatment processes. Therefore, they play a key role in this renovation.

[0003] Inclined plate sedimentation tanks utilize an inclined plate structure to improve sedimentation efficiency, playing a crucial role in wastewater treatment. By increasing the sedimentation surface area and shortening the sedimentation path, they effectively enhance particle separation and are suitable for sedimentation requirements in a variety of water quality conditions.

[0004] In actual applications, it has been found that when the sludge accumulated on the inclined plate reaches a certain weight, it will fall to the sludge discharge area at the bottom of the sedimentation tank under the action of gravity. If the inclined plate is not designed at an appropriate angle, the sludge may not flow smoothly to the sludge collection area and easily accumulate on the surface of the inclined plate. The sludge accumulates on the inclined plate for a long time and becomes more sticky, which makes it more difficult to clean. Therefore, a sedimentation tank for the renovation of old sewers is proposed. Utility Model Content

[0005] The utility model proposes a sedimentation tank for the reconstruction of old sewers, which can adjust the inclination angle of the inclined plate to solve the problem of sludge accumulation on the inclined plate due to the fixed inclination angle of the inclined plate. At the same time, the sludge on the inclined plate can be loosened by the vibration of the inclined plate, thereby effectively cleaning the sludge on the inclined plate.

[0006] The utility model is realized through the following technical solutions: a sedimentation tank for the reconstruction of old sewers, comprising a sedimentation tank, wherein the sedimentation tank comprises a tank body and an inclined plate, the bottom of the left side of the tank body is connected with a water inlet pipe, the top of the right side of the tank body is connected with a drain pipe, and the drain pipe extends to the interior of the tank body, and one end of the drain pipe extending to the interior of the tank body is fixed to the tank body, a drainage hole is opened on the drain pipe, a mud collecting plate is fixed to the inner bottom wall of the tank body, the bottom of the tank body is connected with a mud discharge pipe, and the mud discharge pipe extends to the top of the mud collecting plate, and a valve is installed at one end of the mud discharge pipe outside the tank body.

[0007] A vibration mechanism is provided in the pool body, and the vibration mechanism includes a mounting block rotatably connected to the pool body through a rotating rod, a vibration spring is fixed on the mounting block, and the vibration spring is fixed to the lower end of the inclined plate. The vibration mechanism also includes a dual-axis motor fixed to the inclined plate, and a rotating shaft is fixed to the output end of the dual-axis motor, and the end of the rotating shaft away from the dual-axis motor is rotatably connected to the pool body through a bearing.

[0008] An eccentric block is fixed on the rotating shaft, and the vibration mechanism also includes a support rod fixed to the pool body, and the support rod is in contact with the inclined plate. A limit block is fixed in the pool body, and the outer contour of the limit block is a rectangle.

[0009] The vibration mechanism is provided with an angle adjustment component, and the angle adjustment component includes a mounting cylinder fixed to the rotating shaft, and a blade is fixed on the mounting cylinder.

[0010] The utility model provides a sedimentation tank for the reconstruction of old sewers, which has the following beneficial effects:

[0011] 1. The sedimentation tank for the reconstruction of old sewers starts the dual-axis motor to drive the rotating shaft, mounting cylinder and blades to rotate. The rotating blades can stir the water inside the tank body, thereby causing the inclined plate, vibration spring and mounting block to rotate in the tank body, increasing the inclination angle of the inclined plate, making it easier for the sludge on the inclined plate to slide onto the mud collecting plate, solving the problem of sludge accumulation on the inclined plate due to the fixed inclination angle of the inclined plate. While the rotating shaft rotates, it will also drive the eccentric block to rotate. The rotation of the eccentric block will generate asymmetric centrifugal force, thereby causing the inclined plate and vibration spring to vibrate, which can loosen the sludge on the surface of the inclined plate. The sludge on the inclined plate can be effectively cleaned through the synergistic effect of the inclined plate angle adjustment and the inclined plate vibration. BRIEF DESCRIPTION OF THE DRAWINGS

The vibration mechanism 2 also includes a dual-axis motor 203 fixed to the inclined plate 106, and a rotating shaft 204 is fixed to the output end of the dual-axis motor 203.

[0025] Please refer to Figure 3 and Figure 4 An eccentric block 205 is fixed on the rotating shaft 204. The rotation of the rotating shaft 204 will drive the eccentric block 205 to rotate, and the rotation of the eccentric block 205 will generate an asymmetric centrifugal force. The vibration mechanism 2 also includes a support rod 206 fixed to the pool body 101, and the support rod 206 is in contact with the inclined plate 106.
