In the sedimentation zone of horizontal or vertical flow sedimentation tanks, inclined parallel tubes or parallel pipes are used to divide the sedimentation zone into a series of shallow sedimentation layers. The treated and settled particles move and separate in each shallow sedimentation layer, and the settled particles are located inside the sedimentation chamber.

[0003] According to Chinese Utility Model Patent Application No. CN202420282131.2, a sludge scraping device for an inclined tube sedimentation tank and an inclined tube sedimentation tank are proposed. The utility model describes that "the sludge scraping device of this utility model can clean the sludge in the sludge hopper through the scraper body, and the air flowing out through the air outlet branch pipe can generate airflow by contacting water, which can wash the inclined tube packing. In addition, the air outlet branch pipe rotates synchronously with the drive shaft, thereby achieving 360° rotation, which can cover the entire area of ​​the inclined tube, thereby cleaning the sludge in various positions of the inclined tube."

[0004] The inclined tube sedimentation tank uses a sludge scraper and an inclined tube sedimentation tank. The sludge scraper body and the air outlet branch pipe are driven by a drive shaft to rotate and clean the inner bottom wall of the inclined tube sedimentation tank. When the cross-section of the inclined tube sedimentation tank is rectangular, a large dead corner will be generated during the cleaning process, which will affect the cleaning effect. Improvement is needed. Therefore, a sedimentation tank for waterworks is proposed to solve the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figures 1-7. In this embodiment, a sedimentation tank for a waterworks includes an inclined tube sedimentation tank body 1. The inclined tube sedimentation tank body 1 is existing technology, and the structure of its parts, its connection method, and its working principle have been disclosed, so they will not be described in detail. A sedimentation chamber 2 is fixedly installed at the bottom of the sedimentation tank body 1. The top of the sedimentation chamber 2 is open. A sealing door 3 is rotatably installed on the front of the sedimentation chamber 2. By opening the sealing door 3, the particles inside the sedimentation chamber 2 can be cleaned. Two guide plates 4 are fixedly installed on the inner side wall of the sedimentation chamber 2. The bottom of the two guide plates 4 is connected to a moving mechanism 5. The bottom of the moving mechanism 5 is connected to a cleaning mechanism 6. The cleaning mechanism 6 cleans the inner bottom wall of the sedimentation chamber 2. The base frame 11 is fixedly installed on the main body 1, and the receiving box 9 is placed on the base frame 11. Specifically, the operator first uses the inclined tube sedimentation tank main body 1 to settle the tap water, and after draining the settled tap water from the sedimentation tank main body 1, the settled particles are located inside the sedimentation chamber 2. The sealing door 3 is opened, and the moving mechanism 5 drives the cleaning mechanism 6 to move towards the sealing door 3. The cleaning mechanism 6 cleans the particles on the bottom wall of the sedimentation chamber 2. The dead corners are small during the cleaning process, which improves the cleaning effect.

[0018] In this embodiment, the sedimentation tank 2 has a rectangular cross-section and is located directly below the inclined tube of the inclined tube sedimentation tank body 1.

[0019] Specifically, the settled particles fall vertically onto the inner bottom wall of sedimentation chamber 2.

[0020] In this embodiment, the sealing door 3 is rotatably connected to the front of the sedimentation tank 2 via a hinge, and a sealing strip that fits against the front of the sedimentation tank 2 is fixedly installed on the back of the sealing door 3.

[0021] Specifically, when the sealing door 3 is closed, the sealing strip fits snugly against the front of the sedimentation tank 2, preventing tap water and particulate matter from leaking out.

[0022] In this embodiment, the tops of both guide plates 4 are inclined surfaces, and the tops of the guide plates 4 are provided with multiple guide grooves, which are evenly and equidistantly distributed.

[0023] Specifically, the settled particles fall onto the top of the guide plate 4 and then fall along the guide groove onto the inner bottom wall of the sedimentation tank 2.

[0024] In this embodiment, the moving mechanism 5 includes two linear modules 51, and both guide plates 4 have through holes inside. Two linear modules 51 are fixedly connected inside two through holes. The output ends of both linear modules 51 pass through guide plates 4 and are fixedly mounted with movable frames 52. The bottom of both guide plates 4 is provided with movable holes that match the output ends of the linear modules 51. Electric push rods 53 are fixedly mounted on the inner bottom walls of both movable frames 52. The output ends of both electric push rods 53 pass through movable frames 52 and are fixedly mounted with movable plates 54. The two linear modules 51 and the two electric push rods 53 are all synchronously controlled by a synchronous controller. A synchronous controller is a device specifically designed to control multiple actuators to achieve synchronous movement. By connecting the controllers of the two electric push rods to the synchronous controller, the algorithm and logic of the synchronous controller ensure that the two electric push rods can start and stop simultaneously when they receive instructions, and run at the same speed. The control circuit of the synchronous controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0025] Specifically, the two linear modules 51 are synchronously controlled by the synchronous controller to drive the two moving frames 52, the two electric push rods 53 and the moving plate 54 to move horizontally, and the electric push rods 53 are synchronously controlled by the synchronous controller to drive the moving plate 54 to move vertically.

[0026] In this embodiment, the cleaning mechanism 6 includes a first mounting plate 61, which is fixedly connected to the bottom of the movable plate 54. The bottom of the first mounting plate 61 is threadedly connected to a second mounting plate 62 by eight bolts. A cleaning plate 63 is fixedly installed on the bottom of the second mounting plate 62. One side of the cleaning plate 63 is arc-shaped. The left and right sides of the cleaning plate 63 are respectively attached to the left and right sides of the inner wall of the sedimentation tank 2. The bottom of the cleaning plate 63 is attached to the inner bottom wall of the sedimentation tank 2.

[0027] Specifically, by screwing the bolts into the interior of the first mounting plate 61 and the second mounting plate 62, the second mounting plate 62 can be installed at the bottom of the first mounting plate 61. The moving plate 54 drives the first mounting plate 61, the second mounting plate 62 and the cleaning plate 63 to move horizontally, and the cleaning plate 63 cleans the inner bottom wall and part of the inner side wall of the sedimentation tank 2.

[0028] The working principle of the above embodiments is as follows: First, the staff uses the inclined tube sedimentation tank body 1 to settle the tap water. After draining the settled tap water from the sedimentation tank body 1, the settled particles are located inside the sedimentation chamber 2. Then, the sealing door 3 is opened, and the synchronous controller is used to synchronously control the electric push rod 53 to drive the moving plate 54 and the cleaning plate 63 to move vertically to the designated position, so that the cleaning plate 63 contacts the inner bottom wall of the sedimentation chamber 2. The synchronous controller is also used to synchronously control the two linear modules 51 to drive the two moving frames 52, the two electric push rods 53, the moving plate 54, and the cleaning plate 63 to move horizontally. The cleaning plate 63 cleans the inner bottom wall of the sedimentation chamber 2 and the bottom of the left and right sides of the inner wall of the sedimentation chamber 2. The dead corners are smaller during the cleaning process, which improves the cleaning effect.
