Description

Technical Field

[0001] The present application relates to the technical field of water treatment engineering, and in particular to a design method and simulation structure of a pre-sedimentation tank after a double water intake pump. Background Art

[0002] With the acceleration of industrialization and urbanization, the effective use and treatment of water resources have become particularly important. In the process of water resource treatment, the pre-sedimentation tank is a vital component. Its main function is to remove suspended solids and other particulate matter in the water, thereby reducing the pressure of the subsequent treatment stage. The design and operation of the pre-sedimentation tank directly affects the efficiency and treatment quality of the entire water treatment system.

[0003] The existing technology still has the following problems:

[0004] 1. Traditional pre-sedimentation tank designs usually use a single water inlet, that is, all water flows into the sedimentation tank through a common water inlet. This design is simple, but it often cannot effectively cope with large flow rates or large fluctuations in water quality. Under high flow conditions, a single water inlet may cause the water inlet speed to be too fast, the water flow is dynamically unstable, and the sedimentation effect is affected. In addition, when the input water quality deteriorates or contains higher concentrations of suspended solids, it is difficult for a single system to adjust quickly to maintain treatment efficiency.

[0005] 2. Traditional pre-sedimentation tanks rely on the natural sedimentation process to remove suspended solids from the water. This process is usually inefficient, especially when treating large flows of water. The speed of natural sedimentation is affected by many factors, including water temperature, particle size, and particle density, which slows down the sedimentation process, prolonging the entire water treatment cycle and limiting treatment capacity.

[0006] 3. During the long-term operation of the pre-sedimentation tank, a large amount of sediment will accumulate at the bottom of the tank. Traditional dredging methods usually rely on manual or mechanical excavation, which is not only time-consuming and labor-intensive, but also often leads to interruptions in the water intake process. In addition, frequent mechanical intervention may cause damage to the tank structure, increasing maintenance costs and risks. Summary of the invention

DETAILED DESCRIPTION

[0033] Traditional pre-sedimentation tanks are usually designed with a single water inlet method.

The present invention accelerates the sedimentation of silt particles to the bottom of the tank under the action of centrifugal force and gravity through the sedimentation assembly, shortening the sedimentation path and time; during the long-term operation of the pre-sedimentation tank, a large amount of sediment will accumulate at the bottom of the tank. The present invention uses the sand removal assembly to allow the silt particles to enter the sand collecting mechanism for centralized collection, which is convenient for regular cleaning and ensures that the silt particles are quickly discharged.

[0037] See also Figure 3 and Figure 4As shown, the gate assembly 6 includes a support frame 61, which is fixedly connected to the upper surface of the partition wall 3. A winch 62 is provided at the top of the support frame 61, and a correction mechanism 63 is provided at the bottom wall of the top of the support frame 61. The correction mechanism 63 is used to prevent the traction rope 64 from shaking when the traction rope 64 is raised or lowered. The outer surface of the winch 62 is wrapped with a traction rope 64, which passes through the support frame 61 and the correction mechanism 63, and the traction rope 64 is located in the middle part of the support frame 61. The bottom end of the traction rope 64 is fixedly connected to the adjustment mechanism 65, and the two ends of the adjustment mechanism 65 are provided with a hanging rope 66. The bottom end of the hanging rope 66 is sleeved with a lifting ear 67, and a gate body 68 is fixedly installed on the lower surface of the lifting ear 67. There are two lifting ears 67.

When the gate body 68 and the bottom end of the partition wall 3 are flush, the gate body 68 covers the connecting groove. When the two pre-sedimentation tanks 2 need to be connected, the gate body 68 needs to be lifted in the inner cavity of the partition wall 3. At this time, the winch 62 drives the traction rope 64 to be rolled up, and the rolling of the traction rope 64 drives the adjustment mechanism 65 to be lifted, and the adjustment mechanism 65 drives the suspension rope 66 to move upward, and the suspension rope 66 drives the lifting lug 67 to move upward, so that the lifting lug 67 drives the gate body 68 to move in the inner cavity of the partition wall 3, so that the two pre-sedimentation tanks 2 are connected, so that when one of the pre-sedimentation tanks 2 needs to be repaired or maintained, the gate body 68 between the pre-sedimentation tanks 2 can be closed to isolate the side that needs to be repaired or cleaned, while the other side continues to operate normally, ensuring the continuity of water supply and the stability of the system. For example, when the surface water intake system needs to be overhauled, the groundwater intake system can still continue to supply water; and when one side of the pre-sedimentation tank 2 needs to be cleaned or maintained, the other side can operate independently. This design ensures that the system can maintain stable water treatment capabilities under different working conditions, avoiding the risk of the entire system shutting down due to a single device failure.

[0038] See also Figure 4 and Figure 5As shown, the correction mechanism 63 includes a fixed ring 631, the fixed ring 631 is fixedly connected to the top and bottom walls of the support frame 61, the inner cavity of the fixed ring 631 is slidably connected to the first sliding rod 632, one end of the first sliding rod 632 is fixedly connected to the first correction ring 633, the outer surface of the first sliding rod 632 is sleeved with a first spring 634, the first spring 634 is located between the fixed ring 631 and the first correction ring 633, the inner cavity of the first correction ring 633 is slidably connected to the second sliding ring 635, one end of the second sliding ring 635 is fixedly installed with a second correction ring 636, the outer surface of the second sliding ring 635 is sleeved with a second spring 637, the second spring 637 is located between the first correction ring 633 and the second correction ring 636. 6, the traction rope 64 passes through the second correction ring 636, and when the traction rope 64 shakes during lifting and lowering, the second correction ring 636 moves, and the second correction ring 636 moves to compress the second spring 637 or the first spring 634. Since the fixing ring 631 is fixed, the first correction ring 633 and the second correction ring 636 are restored to their original positions under the elastic force of the first spring 634 and the second spring 637, so that the second correction ring 636 always remains in the original position. Therefore, when the traction rope 64 shakes, the second correction ring 636 has the effect of correcting the traction rope 64, which is convenient for maintaining stability when the gate body 68 goes up and down, preventing the gate body 68 from colliding with the partition wall 3, and improving the service life of the equipment.

[0039] See also Figure 4 and Figure 6 As shown, the adjustment mechanism 65 includes an adjustment frame 651, the inner cavity of the adjustment frame 651 is rotatably connected with a first threaded rod 652, and sliders 653 are sleeved at both ends of the first threaded rod 652. The slider 653 and the first threaded rod 652 are threadedly connected, and the threads at both ends of the first threaded rod 652 are in opposite directions.

[0040] See also Figure 2 and Figure 7As shown, the sedimentation assembly 7 includes a sedimentation cylinder 71, the inner cavity of the sedimentation cylinder 71 is rotatably connected to a spiral blade 72, the upper surface of the sedimentation cylinder 71 is provided with a first motor 73, the output end of the first motor 73 is sleeved with the spiral blade 72, there is a gap between the bottom end of the sedimentation cylinder 71 and the bottom of the pre-sedimentation tank 2, the middle part of the sedimentation cylinder 71 is connected to the water intake valve chamber 5, and the silt particles are directly at the lowest end. When water enters the sedimentation cylinder 71, the operation of the first motor 73 drives the spiral blade 72 to rotate so that the silt particles attached to the water quickly settle to the bottom of the pre-sedimentation tank 2, that is, the water flow entering the pre-sedimentation tank 2 forms a vortex, and the silt particles are accelerated to settle to the bottom of the tank under the action of centrifugal force, thereby shortening the sedimentation path and time.

[0041] Embodiment 2:

[0042] See also Figure 1 and Figure 8 As shown, the sand removal assembly 8 includes a second threaded rod 81, which is rotatably connected to the inner wall of the sedimentation tank body 1, and the outer surface of the second threaded rod 81 is connected to a push plate 82 by a thread, and the push plate 82 is slidably connected to the inner wall of the pre-sedimentation tank 2.

The movement of the push plate 82 drives the push plate 82 to push the silt particles at the bottom of the pre-sedimentation tank 2, so that the silt particles enter the sand collecting mechanism 84 for centralized collection, which is convenient for regular cleaning. After the silt particles are scraped to the sand collecting mechanism 84 at the edge of the pool, they naturally flow to the middle of the sand collecting mechanism 84 by gravity, ensuring rapid discharge and avoiding re-suspension. This application effectively improves the efficiency of silt removal, reduces the need for manual maintenance, maintains water quality, and reduces maintenance costs.

When the box 841 is fitted, the sand collecting trough 844 is located between the two guide plates 842. When the mud and sand particles are pushed to the dust collecting box 841, the guide plates 842 are used to guide the mud and sand particles to enter the inner cavity of the sand collecting trough 844. By regularly pulling the handle 845, the collecting block 843 is driven to slide in the inner cavity of the dust collecting box 841 to expose the sand collecting trough 844. At this time, the mud and sand particles can be discharged. At the same time, the collecting block 843 body has a shielding effect between the guide plates 842 to prevent excess mud and sand particles at the bottom of the pre-sedimentation tank 2 from leaking between the guide plates 842.

[0044] In summary, two pre-sedimentation tanks 2 and two water intake valve chambers 5 are provided on the sedimentation tank body 1, and water is taken in by a conduit 4, which is connected by a diverter. A diverter can be set on a single water intake pipeline to distribute the water flow equally or in a predetermined proportion to two independent water inlet pipes, each of which is connected to an independent pre-sedimentation tank 2 of the pre-sedimentation tank 2. Each pre-sedimentation tank 2 is equipped with independent inlet and outlet control valves, which can be opened or closed as needed; a gate assembly 6 is used to connect and isolate the two pre-sedimentation tanks 2.
