Example

[0043] Reference Figures 1 to 3In order to solve the above-mentioned technical problem of low efficiency in salvaging foreign bodies in sedimentation tanks, the utility model provides a wastewater treatment sedimentation tank, including: a wastewater tank 1, a lifting mechanism 3 and a scraping mechanism 4. It also includes a linear module 2 and a guide rail 21 symmetrically arranged on both sides of the wastewater tank 1, and the linear module 2 and the guide rail 21 are both arranged horizontally, and their lengths are the same as the length of the wastewater tank 1. The lifting mechanism 3 is arranged on the linear module 2 and the guide rail 21, and is used to drive the lifting mechanism 3 to move horizontally. The scraping mechanism 4 is arranged on the lifting mechanism 3, and is used to clean foreign bodies in the wastewater tank 1. In this embodiment, a lifting mechanism 3 and a scraping mechanism 4 are arranged above the wastewater pool 1. Through the arrangement of the lifting mechanism 3, the scraping mechanism 4 can be lifted up and down, thereby entering the wastewater pool 1 and cleaning the foreign matter inside it. The wastewater pool 1 is provided with a linear module 2 and a guide rail 21 on both sides, and the lifting mechanism 3 is installed on the linear module 2 and the guide rail 21, thereby the linear module 2 can drive the scraping mechanism 4 to move horizontally in the wastewater pool 1, and the foreign matter inside the wastewater pool 1 is pushed to gather in one place and clean it by moving, so as to achieve the effect of quickly cleaning the foreign matter. That is, the above-mentioned technical problem of low efficiency in cleaning foreign matter in the sedimentation tank is solved.

[0044] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the scraping mechanism 4 includes: a mounting frame 41, a No. 1 filter 42, a movable plate 43 and a No. 2 filter 44. The center of the mounting frame 41 is hollow. The No. 1 filter 42 is fixedly arranged at the center of the mounting frame 41, and the No. 1 filter 42 is in an upright state. The No. 1 filter 42 installed upright can push the foreign matter inside the wastewater tank 1 under the drive of the linear module 2, so that the foreign matter in the wastewater tank 1 can be pushed from one end of the wastewater tank 1 to the other end, so as to achieve the effect of concentrating the foreign matter and facilitate its treatment. The movable plate 43 is rotatably arranged at the bottom of the mounting frame 41, and the movable plate 43 is located below the No. 1 filter 42. The center of the movable plate 43 is hollow, and the No. 2 filter 44 is fixedly arranged at the center of the movable plate 43.

[0045] Furthermore, the scraping mechanism 4 also includes: a motor 45 fixedly arranged on one side of the mounting frame 41, and the motor 45 is located above the No. 1 filter 42. A driving wheel 46 is arranged on the other side of the mounting frame 41, and the output end of the motor 45 passes through the mounting frame 41 and is connected to the driving wheel 46. A transmission wheel 47 is rotatably arranged on the other side of the mounting frame 41, and the transmission wheel 47 is located below the driving wheel 46 (it should be supplemented that the driving wheel 46 and the transmission wheel 47 are both arranged on the mounting frame 41 through bearings embedded in the mounting frame 41, so as to achieve the effect of the driving wheel 46 and the transmission wheel 47 rotating on the mounting frame 41), one end of the transmission wheel 47 passes through the mounting frame 41, and is connected to the movable plate 43, and a transmission belt 48 is sleeved between the driving wheel 46 and the transmission wheel 47. In this embodiment, the motor 45 drives the driving wheel 46 to rotate, and drives the movable plate 43 to rotate under the installation frame 41 through the traction of the transmission belt 48 and the transmission wheel 47, so that the movable plate 43 can be in two states: vertical and horizontal. Specifically, when the movable plate 43 rotates to the vertical state, it is on the same vertical line with the installation frame 41. In this state, when the lifting mechanism 3 drives it to fall into the wastewater of the wastewater tank 1, the contact area between the movable plate 43 and the installation frame 41 on a straight line and the wastewater becomes smaller, thereby reducing The impact force on the wastewater when falling is low, which avoids the sediment in the wastewater being mixed with the wastewater again due to excessive falling force; when the movable plate 43 enters the wastewater, it can be rotated to a horizontal state, so that when the scraping mechanism 4 moves from one end of the wastewater tank 1 to the other end, the movable plate 43 is in contact with the inner wall of one end of the wastewater tank 1, and is driven up by the lifting mechanism 3, so that the No. 2 filter 44 on the movable plate 43 drives the foreign matter pushed and moved by the No. 1 filter 42 and separates it from the wastewater, thereby achieving the effect of removing foreign matter.

[0046] For further information, please refer to Figure 3As shown, in this embodiment, when the movable plate 43 moves in a horizontal state inside the wastewater tank 1, one end of the movable plate 43 collides with the inner wall of one end of the wastewater tank 1, which causes the wastewater inside the wastewater tank 1 to shake. In order to reduce the influence of shaking on the sedimentation effect of the wastewater tank 1, the movable plate 43 also includes two buffer grooves 431, a mounting groove 432, a spring damping rod 433, a connecting member 434 and a pulley block 435, which are opened at the end of the movable plate 43 away from the mounting frame 41. At least two mounting grooves 432 are respectively opened on the inner wall of the buffer groove 431. One end of the spring damping rod 433 is fixedly arranged in the mounting groove 432. The spring damping rod 433 is used to buffer the impact force generated by the collision between the movable plate 43 and the inner wall of the wastewater tank 1, thereby reducing the amplitude of the wastewater shaking. The connecting member 434 is fixedly arranged at the other end of the spring damping rod 433. The pulley block 435 is fixedly arranged on one side of the connecting member 434. In this embodiment, the pulley block 435 is designed to be used for when the movable plate 43 in a horizontal state collides with the inner wall of the wastewater tank 1. The pulley block 435 can roll on the pulley to make the movable plate 43 rise more smoothly, and the design of the spring damping rod 433 can reduce the impact force generated by the collision between the pulley block 435 and the inner wall of the wastewater tank 1, thereby reducing the shaking amplitude of the wastewater inside the wastewater tank 1.

[0047] Please refer to Figure 1 As shown, the lifting mechanism 3 includes: two mounting blocks 31, a mounting frame 32 and an electric push rod 33. One of the mounting blocks 31 is arranged on the linear module 2 and is fixedly connected to the output end of the linear module 2, and the other mounting block 31 is slidably arranged on the guide rail 21. The two ends of the mounting frame 32 are respectively fixedly arranged on the two mounting blocks 31, and the mounting frame 32 is located above the wastewater tank 1. The linear module 2 can drive the mounting block 31 and the mounting frame 32 above it to move horizontally above the wastewater tank 1. One end of at least two electric push rods 33 is fixedly arranged on the mounting frame 32, and the other end of the electric push rod 33 is fixedly connected to the mounting frame 41. The design of the electric push rod 33 can drive the mounting frame 41 to move up and down, thereby driving the mounting frame 41 to enter and leave the wastewater tank 1.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
