[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-3 A wastewater treatment device for a wastewater treatment plant includes a sedimentation tank body 1, and a cleaning mechanism is provided inside the sedimentation tank body 1.

[0023] The cleaning mechanism includes a push plate 2 installed inside the sedimentation tank body 1. The front and rear ends of the push plate 2 are fixedly connected to sliders 3. The front and rear inner sidewalls of the sedimentation tank body 1 are provided with grooves 4 that match the two sliders 3 respectively. The interior of the two grooves 4 is rotatably connected with screws 5 that are threadedly connected to the two sliders 3 respectively.

[0024] The cleaning mechanism also includes two extension plates 6 fixedly connected to the left end of the upper surface of the sedimentation tank body 1 and distributed front and back. Rotary rollers 7 are rotatably connected between the two extension plates 6 and the lower left side of the interior of the sedimentation tank body 1. A transmission belt 8 is driven between the two rotary rollers 7. Multiple evenly distributed shovel grooves 9 are fixedly connected to the outer wall of the transmission belt 8.

[0025] In this embodiment: when cleaning the sediment and impurities settled at the bottom of the sedimentation tank body 1, the two screws 5 rotate in the same direction. The two screws 5, together with the two sliders 3, drive the push plate 2 to move to the left. Since the rotation direction and thread direction of the two screws 5 are the same, the push plate 2 can be driven to move smoothly through the two screws 5 with the same rotation direction and thread direction. Then, the push plate 2 pushes the sediment and impurities settled at the bottom of the sedimentation tank body 1 to move towards the transmission belt 8, and makes the sediment and impurities enter the shovel groove 9. At the same time, the upper roller 7 rotates, and the upper roller 7 rotates to move the sediment and impurities to the lower roller 8. The rotating roller 7, in conjunction with the lower rotating roller 7, drives the transmission belt 8 to rotate. The transmission belt 8 drives multiple shovels 9 to rotate, thereby conveying mud and impurities through the rotating shovels 9. Since the upper end of the transmission belt 8 extends above the sewage discharge trough 17, the transmission belt 8 and the multiple shovels 9 can convey mud and impurities into the sewage discharge trough 17 and then discharge them through the sewage discharge trough 17. This automatically cleans the mud and impurities settled inside the sedimentation tank body 1, improving the efficiency of mud and impurity cleaning while reducing the labor burden of the staff.

[0026] As a technical optimization of this utility model, a mounting box 10 is fixedly connected to the right side wall of the sedimentation tank body 1. The right ends of the two screws 5 extend into the interior of the mounting box 10 and are fixedly connected to the first synchronous pulley 11. A rotating shaft 12 is rotatably connected inside the mounting box 10. Two second synchronous pulleys 13 distributed on the left and right are fixedly connected to the outer wall of the rotating shaft 12. A synchronous belt 14 is connected between the two first synchronous pulleys 11 and the two second synchronous pulleys 13.

[0027] In this embodiment: the rotating shaft 12 rotates, which drives two second synchronous pulleys 13 to rotate. The two second synchronous pulleys 13, together with two synchronous belts 14, drive two first synchronous pulleys 11 to rotate. The two first synchronous pulleys 11 drive two screws 5 to rotate in the same direction.

[0028] As a technical optimization of this utility model, a first drive motor 15 is installed on the rear end face of the rear extension plate 6, and the output end of the first drive motor 15 is fixedly connected to the rotating roller 7 located above.

[0029] In this embodiment, the first drive motor 15 can drive the upper rotating roller 7 to rotate.

[0030] As a technical optimization of this utility model, a second drive motor 16 is installed on the right side wall of the mounting box 10, and the output end of the second drive motor 16 is fixedly connected to the rotating shaft 12.

[0031] In this embodiment, the second drive motor 16 can drive the rotating shaft 12 to rotate.

[0032] As a technical optimization of this utility model, a sludge discharge trough 17 is fixedly connected to the left side wall of the sedimentation tank body 1, and the upper end of the transmission belt 8 extends above the sludge discharge trough 17.

[0033] In this embodiment: the sludge and impurities can be discharged through the sludge trough 17, and the upper end of the transmission belt 8 extends above the sludge trough 17, which can transport the sludge and impurities into the interior of the sludge trough 17.

[0034] As a technical optimization of this utility model, the lower left side of the interior of the sedimentation tank body 1 is set as an arc-shaped structure that matches the operating path of the multiple shovel grooves 9.

[0035] In this embodiment, the lower left side of the interior of the sedimentation tank body 1 is set with an arc-shaped structure that matches the operating path of the multiple shovel grooves 9, which enables the multiple shovel grooves 9 to rotate smoothly and avoids motion interference to the operation of the multiple shovel grooves 9.

[0036] As a technical optimization of this utility model, the rotation direction and thread direction of the two screws 5 are the same.

[0037] In this embodiment, the two screws 5 rotate in the same direction and have the same thread direction. The two screws 5 with the same rotation direction and thread direction can drive the push plate 2 to move smoothly.

[0038] The working principle and usage process of this utility model are as follows: When cleaning the sediment and impurities settled at the bottom of the sedimentation tank body 1, the second drive motor 16 drives the rotating shaft 12 to rotate, the rotating shaft 12 drives the two second synchronous pulleys 13 to rotate, the two second synchronous pulleys 13 cooperate with the two synchronous belts 14 to drive the two first synchronous pulleys 11 to rotate, the two first synchronous pulleys 11 drive the two screws 5 to rotate in the same direction, the two screws 5 cooperate with the two sliders 3 to drive the push plate 2 to move to the left, and then the push plate 2 pushes the sediment and impurities settled at the bottom of the sedimentation tank body 1 to move towards the transmission belt 8, and makes the sediment and impurities enter the shovel trough 9. At the same time, the first drive motor 15 drives the upper rotating roller 7 to rotate, the upper rotating roller 7 cooperates with the lower rotating roller 7 to drive the transmission belt 8 to rotate, the transmission belt 8 drives the multiple shovel troughs 9 to rotate, and then the sediment and impurities are transported to the inside of the sewage discharge trough 17 through the rotating multiple shovel troughs 9, and then discharged through the sewage discharge trough 17, thereby automatically cleaning the sediment and impurities settled inside the sedimentation tank body 1.
