Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tanks, in particular to an environment-friendly rainwater sedimentation tank. Background Art

[0002] As a new type of rainwater treatment facility, the environment-friendly rainwater sedimentation tank has received wide attention for its high efficiency, economy and environmental protection. By utilizing the gravity sedimentation effect, it can effectively remove impurities such as suspended solids and sediment in rainwater, reduce the pressure on the urban drainage system, and at the same time reduce the risk of water pollution. In addition, the environment-friendly rainwater sedimentation tank also has good adaptability and scalability, and can be widely used in rainwater collection and treatment in urban roads, squares, buildings and other places.

[0003] In the prior art, when traditional rainwater sedimentation tanks carry out rainwater sedimentation, they usually stand still for a period of time to naturally separate water and silt. However, after the water is pumped out, the silt at the bottom of the sedimentation tank becomes hard due to long-term air drying. This hardened silt increases the difficulty of subsequent cleaning work. It is not only more laborious to clean, but also significantly prolongs the cleaning time. When a driving device is used for cleaning, the hardened silt will significantly increase the load of the driving device, making the whole cleaning process extremely strenuous, thus reducing the work efficiency.

Specific embodiments

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1-4 shown, the present utility model provides an environment-friendly rainwater sedimentation tank, including a sedimentation tank body 1. A crushing mechanism 2 is fixedly connected to the outer surface of the sedimentation tank body 1. The crushing mechanism includes two U-shaped plates 201 and a third motor 210. Two sliding grooves 202 are opened at the bottom of each of the two U-shaped plates 201. First motors 203 are arranged on the outer surfaces of the two U-shaped plates 201. The output ends of the two first motors 203 slidably penetrate the outer surfaces of the two U-shaped plates 201 and extend to one side. The output ends of the two first motors 203 are fixedly connected with two first threaded screw rods 204. Two sliding blocks 205 are threadedly connected to the outer surfaces of the two first threaded screw rods 204. Two cylinders 206 are arranged at the bottom of each of the two sliding blocks 205. The outer surfaces of the two U-shaped plates 201 are fixedly connected to the outer surface of the sedimentation tank body 1. The telescopic ends of the two cylinders 206 are provided with two second motors 207. The output ends of the two second motors 207 are fixedly connected with two connecting rods 208. A plurality of crushing blades 209 are arranged in a row and fixedly connected to the outer surfaces of the two connecting rods 208. The third motor 210 is arranged on the outer surface of the sedimentation tank body 1. The output end of the third motor 210 slidably penetrates the outer surface of the sedimentation tank body 1 and extends to one side. The output end of the third motor 210 is fixedly connected with a second threaded screw rod 211. A push plate 212 is threadedly connected to the outer surface of the second threaded screw rod 211.

[0023] The effect achieved by the entire Embodiment 1 is that during use, first, start the two first motors 203 on the two U-shaped plates 201, and their output ends drive the two first threaded lead screws 204 to start rotating. As the two first threaded lead screws 204 rotate, the two sliders 205 smoothly move linearly in the two sliding grooves 202. Subsequently, by starting the two cylinders 206, their telescopic ends adjust the two second motors 207 up and down to a suitable position to meet the crushing requirements at different heights. Then, by starting the two second motors 207, their output ends drive the two connecting rods 208 to rotate. Driven by the two connecting rods 208, multiple crushing blades 209 start to rotate at high speed to effectively crush the sludge in the sedimentation tank, thereby improving the efficiency and smoothness of the subsequent push plate 212 when cleaning the sludge. Finally, start the third motor 210, and its output end makes the second threaded lead screw 211 start to rotate. As the second threaded lead screw 211 rotates, the push plate 212 starts to move along a preset path, thereby realizing the cleaning of the sludge in the sedimentation tank body 1. Under the action of the crushing mechanism 2, the precipitated sludge can be effectively crushed, effectively avoiding the situation where the sludge hardens due to long-term deposition, ensuring the fluidity of the sludge. Through the crushing treatment, not only is the sludge easier to clean, but also the load pressure of the driving device during the pushing process is significantly reduced, making the entire cleaning process smoother and improving the work efficiency.

[0024] Embodiment 2 is as Figures 1-4 shown, the outer surface of the sedimentation tank body 1 is fixedly communicated with a water outlet pipe 11, and a filter plate 12 is fixedly connected to the inner wall of the water outlet pipe 11.

[0025] The effect achieved by the entire Embodiment 2 is that during use, after rainwater enters the sedimentation tank and undergoes sedimentation for a period of time, first, the rainwater in the sedimentation tank is pumped out through the water outlet pipe 11. At this time, under the action of the filter plate 12, it can effectively block sundries such as fallen leaves, thereby reducing the interference of impurities in the subsequent treatment process and improving the efficiency of rainwater treatment.

[0026] Working principle: When in use, rainwater enters the sedimentation tank and after a period of sedimentation, first, the rainwater in the sedimentation tank is pumped out through the water outlet pipe 11. At this time, under the action of the filter plate 12, sundries such as fallen leaves can be effectively blocked, thereby reducing the interference of impurities in the subsequent treatment process. Subsequently, two first motors 203 are started to drive two first threaded lead screws 204 to rotate. As the two first threaded lead screws 204 rotate, the two sliding blocks 205 move smoothly in a straight line in the two sliding grooves 202. Then, by starting two cylinders 206, the two second motors 207 are adjusted up and down to a suitable position to meet the crushing requirements at different heights. Subsequently, by starting two second motors 207, the two connecting rods 208 are driven to rotate. Driven by the two connecting rods 208, a plurality of crushing blades 209 start to rotate at high speed to effectively crush the sludge in the sedimentation tank. Finally, the third motor 210 is started to make the second threaded lead screw 211 rotate. As the second threaded lead screw 211 rotates, the push plate 212 starts to move along a preset path, thereby realizing the cleaning of the sludge in the sedimentation tank body 1.

[0027] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
