[0001] This invention relates to the field of wastewater treatment technology, and in particular to a multi-stage sedimentation-assisted wastewater treatment device for water environment management. Background Technology

[0002] Multi-stage sedimentation-assisted wastewater treatment equipment is used in the fields of river water body restoration, municipal sewage and light industrial wastewater treatment. It relies on a graded and zoned sedimentation structure to separate large particulate impurities, suspended colloids and fine pollutants in sewage in stages, and is supplemented by flocculation, flow guidance and interception structures to achieve sewage purification.

[0003] When treating wastewater by sedimentation, workers need to manually add flocculants to the wastewater to promote the sedimentation of impurities. In addition, the agent needs to be added at the inlet. The manual addition is inconvenient and poses certain dangers.

[0004] Therefore, a multi-stage sedimentation-assisted wastewater treatment device needs to be designed to solve the above problems. Summary of the Invention

[0011] As a preferred embodiment of the present invention, the cross-sectional diameter of the movable block is smaller than the diameter of the opening.

[0012] As a preferred embodiment of the present invention, the container is provided with an agitation assembly, the agitation assembly includes a stirring shaft, the stirring shaft is rotatably mounted on a lower limiting plate, a plurality of stirring rods are fixed on the stirring shaft, a drive gear is fixedly sleeved on the stirring shaft, and a transmission assembly is provided on both the container and the mounting frame.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1: This example describes a multi-stage sedimentation-assisted wastewater treatment device for water environment management, as disclosed in this example. Figures 1-5This device is specifically designed for open water environments such as rivers, lakes, and landscape ponds. It achieves wastewater purification based on the principle of multi-stage sedimentation. It solves the problems of traditional dosing equipment such as reliance on electricity, uneven dosing, easy clogging, and cumbersome operation. It achieves integrated operation with no electricity drive, automatic dosing, uniform dosing, and anti-clogging and anti-caking, which greatly improves the efficiency of sedimentation treatment. The device includes sedimentation tank 1. The specific structure and working principle of sedimentation tank 1 are existing technologies, and the implementation method adopts conventional means. It is not shown in the figure and will not be described in detail here.

[0020] A fixing plate 2 is fixed on the sedimentation tank 1. The fixing plate 2 is welded from stainless steel plate, which has a stable structure and strong load-bearing capacity, providing reliable support for the inlet pipe 3. The inlet pipe 3 is fixed on the fixing plate 2. The inlet pipe 3 is made of corrosion-resistant PVC or galvanized steel pipe. The pipe diameter is matched according to the inlet flow rate. Sewage is smoothly injected into the sedimentation tank 1 through the inlet pipe 3. The inlet direction is tangential to the tank wall, which can reduce the impact of water flow and reduce the disturbance of suspended solids, creating stable conditions for sedimentation. A fixing rod 4 is fixed on the sedimentation tank 1. The fixing rod 4 is set in the vertical direction and is made of rust-proof round steel. A guide rail 5 is fixed at the top of the fixing rod 4. The guide rail 5 is set in the horizontal direction.

[0021] An installation plate 6 is installed above the sedimentation tank 1. The installation plate 6 is made of high-strength lightweight alloy plate, which has good rigidity and light weight, making it easy to move manually. A slide 61 is fixed on the top surface of the installation plate 6. The inner wall of the slide 61 is inlaid with a wear-resistant bushing and slides on the guide rail 5. A pull rod is fixed on the side of the slide 61. The pull rod is made of round steel with a smooth surface and comfortable grip. The end of the pull rod away from the slide 61 extends towards the edge of the sedimentation tank 1. The pull rod makes it convenient for staff to safely control the movement of the installation plate 6 at the edge of the tank without having to go into the tank, thus improving the safety and convenience of operation.

[0022] An opening 62 is provided on the mounting plate 6, and a dosing assembly is provided on the mounting plate 6. The dosing assembly includes a movable block 71, which is placed in the opening 62 and is made of wear-resistant engineering plastic. Limiting plates 72 are fixed to both the upper and lower ends of the movable block 71. The area of ​​the limiting plates 72 is larger than that of the opening 62. Both limiting plates 72 are tightly fitted to the surface of the mounting plate 6, so that the movable block 71 cannot fall out of the opening 62 and can only vibrate and move slightly in the horizontal direction inside the opening 62, ensuring safe operation. The upper limiting plate 72 is connected to the mounting plate 6 by two tension springs 73. The tension springs 73 are designed to facilitate the movement of the movable block 71 and the two limiting plates 72 under force. High-frequency, small-amplitude vibration assists in the descent of the reagent. Below the lower limiting plate 72, a container 75 is installed. The container 75 is an open-top reagent bin made of corrosion-resistant, non-stick material. It is used to store powdered or granular precipitating agents such as polyaluminum chloride, polyacrylamide, and quicklime. The container 75 is connected to the lower limiting plate 72 by several evenly distributed mounting rods 74. The connection is firm and the force is even, so it will not loosen during vibration. The bottom surface of the container 75 has several through holes 751. The diameter of the through holes 751 is set according to the particle size of the reagent. The through holes 751 are evenly distributed on the bottom surface of the container 75 to ensure that the reagent is dispersed during descent, has a wide distribution range, and is more thoroughly mixed with sewage.

[0023] A drive assembly is provided on one side of the container 75. The drive assembly uses the kinetic energy of the incoming water flow to convert it into mechanical power, enabling the whole machine to operate without electricity. The drive assembly includes two fixed frames 82, which are symmetrically arranged facing each other. The structure is strong and the force is uniform. Several blades 83 are fixed on the two fixed frames 82. The blades 83 are made of waterproof and impact-resistant material, and their curvature has been optimized by fluid mechanics. The blades 83 are distributed in a circumferential array, which can efficiently capture the impact force of the water flow and rotate stably. A rotating shaft 84 is fixed on one of the fixed frames 82. The drive assembly also includes a mounting frame 81, which is fixed on the mounting plate 6. The rotating shaft 84 is rotatably mounted on the mounting frame 81 and can rotate continuously and synchronously with the blades 83.

[0024] The mounting plate 6 is equipped with a vibration assembly, which converts the rotational motion of the rotating shaft 84 into periodic impact vibrations on the container 75 to prevent the medicine from clogging, bridging, or accumulating. The vibration assembly includes a rotating rod 91, which is rotatably mounted on the bottom surface of the mounting plate 6. An eccentric wheel 94 is fixedly sleeved on the rotating rod 91. The eccentric wheel 94 is made of metal, with a moderate eccentricity and uniform impact force, which can continuously trigger the vibration of the container 75. The rotating rod 91 and the rotating shaft 84 are connected by a first bevel gear 92 and a second bevel gear 93 that mesh with each other. The bevel gears have high meshing accuracy and stable transmission, which can convert horizontal rotation into vertical rotation and achieve efficient power transmission.

[0025] When performing the dosing operation, the staff first pulls the mounting plate 6 along the guide rail 5 to the edge of the sedimentation tank 1. The operation is safe and does not require bending over. Then, the quantitative amount of medicine is put into the container 75. The filling is convenient and does not easily spill. Then, the mounting plate 6 is pushed smoothly to the upper part of the middle of the sedimentation tank 1. The positioning is accurate and the dosing range covers the entire tank. In this case, one of the blades 83 is set directly in the direction of the outlet of the inlet pipe 3. When the sewage is injected into the sedimentation tank 1 through the inlet pipe 3, the flowing sewage forms a stable water flow impact force, which can drive several blades 83 to rotate continuously. This causes the two fixed frames 82 to rotate synchronously. When the fixed frames 82 rotate, they can drive the rotating shaft 84 to rotate stably. When the rotating shaft 84 rotates, it can precisely drive the rotating rod 91 to rotate through the meshing first bevel gear 92 and second bevel gear 93. When the rotating rod 91 rotates, the eccentric wheel 94 on it rotates synchronously.

[0026] During its rotation, the eccentric wheel 94 periodically and continuously strikes the bottom of the container 75, causing the container 75 to vibrate at a high frequency and with a small amplitude. When the container 75 vibrates, the reagent inside the container 75 will fall slowly and evenly through several through holes 751 under the combined action of vibration and gravity, and fall steadily into the interior of the sedimentation tank 1 to fully mix with the sewage. This achieves electricity-free, automatic, continuous, and uniform dosing, meeting the reagent dosing requirements for multi-stage sedimentation. When the container 75 vibrates, it can simultaneously drive the two limiting plates 72 and the movable block 71 to vibrate together. During this process, the two limiting plates 72 always provide reliable limiting for the container 75, so that the container 75 can only vibrate stably in the horizontal direction and will not move up and down, effectively preventing the container 75 from detaching from the mounting plate 6. The stirring shaft 101 is rotatably installed on the lower limiting plate 72, reserving a structural interface for the subsequent stirring and dispersing function.

[0027] Example 2: Based on Example 1, this example discloses a multi-stage sedimentation-assisted wastewater treatment device for water environment management, referring to... Figures 6-7To address the issue of powdered medicines easily becoming damp and clumping, clogging the through-hole 751, an agitation component and a transmission component are added to automatically disperse, prevent clogging, and loosen the medicine inside the container 75, further improving the stability and reliability of dosing. The container 75 is equipped with an agitation component, which periodically stirs and disperses the clumps and compacted medicine inside the container 75, ensuring that the medicine is always in a loose and flowing state. The agitation component includes a stirring shaft 101, which is rotatably mounted on the lower limiting plate 72. Several stirring rods 102 are fixed on the stirring shaft 101, and a drive gear 1 is fixedly sleeved on the stirring shaft 101. 03. A transmission assembly is provided on both the container 75 and the mounting frame 81. The transmission assembly adopts a hydraulic linkage and non-electric drive design, which converts the rotation of the rotating shaft 84 into the forward and reverse rotation of the stirring shaft 101. The transmission assembly includes a connecting frame 104, a first telescopic rod 105 and a second telescopic rod 107. One end of the connecting frame 104 is connected to the container 75 and the other end is connected to the first telescopic rod 105. It vibrates synchronously with the container 75 without interference. A rack 106 is fixed to the telescopic end of the first telescopic rod 105. The rack 106 is straight and the transmission is smooth. The rack 106 is set directly opposite the drive gear 103, which can precisely mesh and drive.

[0028] The second telescopic rod 107 is fixed on the mounting bracket 81, with a fixed position and stable support. A cam 109 is provided below the second telescopic rod 107. The cam 109 is fixedly sleeved on the rotating shaft 84, and the cam 109 is set directly opposite the telescopic end of the second telescopic rod 107, which can realize periodic pushing operation. The second telescopic rod 107 and the first telescopic rod 105 are connected by a connecting pipe 108. The first telescopic rod 105 and the second telescopic rod 107 have the same structure and both adopt a sealed hydraulic telescopic structure. The first telescopic rod 105 includes an outer cylinder. The outer cylinder is sealed, pressure-resistant, and does not deform. A sliding plug is slidably provided inside the outer cylinder. The sliding plug sealing ring has excellent performance and no internal leakage.

[0029] A push rod is fixed to the side of the slide plug. The push rod is a telescopic part and can move freely in and out of the outer cylinder. The slide plug and the outer cylinder are connected by a return spring. The spring force is stable and can quickly and automatically reset after the external force is lost. When several blades 83 rotate stably under the continuous impact of water flow, the rotating shaft 84 can drive the cam 109 to rotate at a uniform speed. During the rotation, the cam 109 can periodically push the telescopic end of the second telescopic rod 107 to realize continuous telescopic action cycle. When the telescopic end of the second telescopic rod 107 is pushed by the cam 109, the liquid inside the second telescopic rod 107 is pressurized and can smoothly enter the first telescopic rod 105 through the connecting pipe 108, and drive the telescopic end of the first telescopic rod 105 to extend outward. When the telescopic end of the first telescopic rod 105 moves, it can drive the rack 106 to move synchronously in a straight line.

[0030] When the rack 106 moves, it can drive the drive gear 103 meshing with it to rotate, thereby driving the stirring shaft 101 to rotate in a specific direction to achieve forward stirring. Conversely, when the cam 109 rotates to separate from the extension end of the second extension rod 107, under the action of the return spring, the extension ends of the second extension rod 107 and the extension ends of the first extension rod 105 are quickly and automatically reset, so that the rack 106 is automatically reset synchronously. During the reset process, the rack 106 can also drive the stirring shaft 101 to rotate in the opposite direction through the drive gear 103. Therefore, during the entire process of sewage continuously entering the sedimentation tank 1, the stirring shaft 101 can achieve continuous, stable, and periodic forward and reverse rotation. During the rotation of the stirring shaft 101, the several stirring rods 102 on it can stir the powdered agent in the container 75 in all directions without dead angles, and play a role in fully dispersing, loosening, and turning over the agent that is damp, compacted, or clumped.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
