Description

Technical Field

[0001] This utility model relates to the field of water purification and ecological restoration technology, specifically to a purification device suitable for water ecological restoration. Background Technology

[0002] Currently, many rivers, lakes, and scenic water bodies in my country face multiple pressures, including water quality deterioration, surface garbage accumulation, and aquatic ecosystem degradation. Traditional, single-method governance approaches often have limited effectiveness in addressing these complex issues and are prone to drawbacks such as high costs and secondary pollution, failing to meet the urgent need for sustainable ecological restoration.

[0003] In current aquatic ecological restoration technologies, methods such as flow generation and oxygenation, addition of microbial agents, and the installation of biological packing materials for purification are commonly used. However, these technologies typically operate independently in practice, exhibiting significant limitations: for example, a single aeration device can only increase dissolved oxygen but has limited ability to degrade pollutants; while fixed biological packing materials can attach microorganisms, their purification efficiency is low under still or slow-flowing conditions, and they are prone to clogging; and artificially added microbial agents suffer from uneven distribution and easy loss. Furthermore, there is a lack of effective in-situ collection measures for floating debris on the water surface. This single-function, fragmented approach to treatment leads to redundant equipment investment, increased energy consumption, and difficulty in achieving a highly efficient synergistic purification effect, thus hindering the improvement of overall restoration results. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of the aforementioned background technology and provide a purification device suitable for the ecological restoration of aquatic bodies.

[0005] The technical solution of this application is: a purification device suitable for water body ecological restoration, comprising, The support rod is a vertical rod-shaped structure whose lower end is inserted into the bottom of the water area to be treated; A dosing structure, comprising a dosing tank and a perforated pipe communicating with the dosing tank; one end of the perforated pipe is rotatably hinged to the support rod around the axis of the support rod, and the other end extends laterally; a plurality of small holes communicating with the inside and outside of the perforated pipe are evenly distributed on the perforated pipe. The filter structure is fixed on the perforated pipe and can rotate around the axis of the support rod to disturb the water flow in the water area, thereby filtering and purifying the disturbed water flow. The slag collection structure is fixed on the perforated pipe and can rotate around the axis of the support rod along with the perforated pipe to intercept and collect floating objects in the disturbed water flow.

[0006] According to the purification device for water ecological restoration provided in this application, there are multiple perforated pipes, which are evenly spaced around a support rod in the circumferential direction. Each perforated pipe is provided with at least one set of filter structure and / or at least one set of sludge collection structure.

[0007] According to the purification device for water ecological restoration provided in this application, the perforated pipe is provided with only one set of filter structure or only one set of slag collection structure, and the perforated pipes provided with filter structure and the perforated pipes provided with slag collection structure are arranged alternately along the circumferential direction.

[0008] According to the purification device for water ecological restoration provided in this application, at least one set of the filter structure and at least one set of the sludge collection structure are provided on the same perforated pipe, and the sludge collection structure on the same perforated pipe is located on the water-facing side of the filter structure.

[0009] According to the present application, a purification device suitable for water body ecological restoration is provided, wherein the filtration structure includes a packing mesh box fixed on a perforated pipe; the packing mesh box is filled with water purification ceramic granules that perform filtration.

[0010] According to the purification device for water ecological restoration provided in this application, the water purification ceramsite filler is filled in the filler mesh box to form a square box; the water-facing end face of the box is an inclined surface that slopes forward from the bottom to the top in the direction of rotation.

[0011] According to the purification device for water body ecological restoration provided in this application, the sludge collection structure includes a sludge collection net fixed on a perforated pipe; the sludge collection net has a collection port arranged facing the water; the opening direction of the collection port is opposite to the rotation direction of the perforated pipe, and the upper edge of the opening is higher than the water surface.

[0012] According to the purification device for water ecological restoration provided in this application, the dosing tank is fixed at the upper end of the support rod that protrudes above the water surface, and the dosing tank is connected to all perforated pipes through a dosing pipe; a speed regulating valve for controlling the dosing speed is provided on the dosing pipe.

[0013] The advantages of this application are as follows: 1. The purification device of this application ingeniously integrates three mainstream purification technologies—physical filtration (filtration structure), floating matter collection (sludge collection structure), and chemical dosing (dosing structure)—into one device, achieving "multi-functionality in one machine" and solving the problems of dispersed equipment and poor coordination in traditional methods; unlike traditional static filter dams or floating beds, the filtration and sludge collection units of this device can rotate around the axis of the support rod following the perforated pipe, which not only expands the purification treatment range but also generates water flow disturbance, improving purification efficiency; the rotational motion expands its effective range from a point to a circular area, resulting in higher treatment efficiency; the dynamic motion makes the filtration structure less prone to complete blockage by suspended matter, and the sludge collection... The structure can continuously attract new floating debris and has self-cleaning potential; the rotation disturbs the water flow, breaking up the stratification of the water body and increasing the contact frequency and efficiency between water and purification materials (such as fillers and chemicals), avoiding the formation of purification dead zones; the design of inserting the lower end of the support rod into the water bottom provides a stable anchoring point, ensuring the stable operation of the entire rotating mechanism under complex water flow conditions. The structure is simple, reliable, and easy to install and deploy; the dosing structure of this application releases chemicals through small holes on the perforated pipe, and the perforated pipe itself rotates, so that the chemical dosing is no longer a static point, but spreads evenly and over a wide area to the water to be treated as the rotation progresses, greatly improving the utilization rate and mixing effect of the chemicals; 2. The multiple perforated tubes in this application are evenly arranged circumferentially, which balances the forces during rotation, forming a stable "force couple". This greatly reduces the torque borne by the support rod, making the device operate more smoothly, consumes less energy, and has a longer lifespan. The multiple perforated tubes act like a "purification windmill", which can purify the water in the 360° area around the support rod indiscriminately and in all directions, increasing the treatment capacity and coverage area many times over. This provides a basis for flexibly configuring different numbers and types of filter / sludge collection structures on each perforated tube, enhancing the adaptability and scalability of the device. 3. This layout forms a highly efficient "purification pipeline". The slag collection structure at the front intercepts and collects large floating objects, and then the water flows through the filter structure at the rear for fine filtration, which avoids the floating objects clogging the filter structure too early. The alternating arrangement of structures with different functions can organize and disturb the water flow in a more orderly manner, so that the water flow goes through the process of interception, filtration, re-interception, and re-filtration in sequence, resulting in a longer purification path and a more thorough effect. 4. This application also provides another arrangement structure, which realizes the multi-stage purification concept on a single perforated pipe. When the water flows through a perforated pipe, the scum in the water will first enter the scum collection structure. Large particles of scum are collected by the scum collection structure. The water body after the removal of large particles of scum flows through the filter structure, which can be well purified and filtered, avoiding the problem of clogging when the filter structure directly filters water containing large particles of scum. 5. The water purification ceramsite of this application is an excellent biological carrier. Its huge specific surface area can provide an attachment site for water purification microorganisms such as nitrifying bacteria, so as to achieve efficient biodegradation and fundamentally remove pollutants such as ammonia nitrogen and total phosphorus from the water. The packing mesh box itself plays a physical filtration role, while the ceramsite inside performs biological purification, realizing physical-biological combined purification. 6. This application incorporates an inclined surface in the filter structure. When this inclined surface rotates and faces the water flow, it acts like a "wedge" or "pump," generating a downward thrust on the water flow. This forcibly drives the surface water downwards, thereby strongly promoting the vertical exchange between the upper and lower layers of water. In still or temperature-stratified water bodies, the bottom water is often oxygen-deficient. This design effectively breaks down the stratification, bringing oxygen-rich surface water to the bottom layer, improving the sediment environment, and inhibiting anaerobic bacteria activity, which is crucial for ecological restoration. The water flow is guided through the packing mesh box, increasing the contact and retention time between the water and the ceramsite packing, thus improving the efficiency of biological filtration. 7. The opening direction of the collection port in this application is opposite to the rotation direction of the perforated pipe, which ensures that the slag collection net can face and catch the floating objects head-on during rotation, resulting in extremely high collection efficiency; the upper edge of the opening is higher than the water surface, which can prevent the collected floating objects from being washed out or overflowing from above when rotating or when the water flow is fluctuating, thus ensuring the collection effect; the function of collecting floating objects is separated, avoiding interference with the filtration function, and making it easy to clean and maintain them separately. 8. The dosing tank of this application is located above the water surface, which facilitates observation of the remaining amount and replenishment. One main tank supplies chemicals to all perforated pipes, making the system unified and easy to manage. The speed control valve allows operators to precisely adjust the dosing rate according to the water quality, achieving accurate dosing, which not only ensures the effect but also avoids chemical waste and secondary pollution. The high-level dosing tank can use gravity to deliver the chemical solution to the perforated pipes, reducing the dependence on power devices such as pumps, making the system more energy-efficient and reliable.

[0014] This application provides a purification device suitable for water body ecological restoration. Its greatest advantage lies in the fact that it cleverly couples multiple purification mechanisms through a simple rotational motion, achieving a synergistic effect. It can actively transform the aquatic ecological environment, and the efficiency of water purification treatment is greatly improved. Attached Figure Description

Detailed Implementation

[0016] The embodiments of this application are described in detail below, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

Therefore, they should not be construed as limitations on this application.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] This application relates to a purification device suitable for water ecological restoration. The purification device of this application has the functions of water flow disturbance, chemical dosing, filtration and sludge collection. It can carry out efficient purification treatment of the water body and has a simple structure and is easy to operate and construct.

[0021] Specifically, such as Figures 1-2 As shown, this application discloses a purification device suitable for aquatic ecological restoration. The device includes a support rod 1, the lower end of which is inserted into the bottom sediment layer of the water body to be treated by driving, pressing, or anchoring, and is stably installed in a vertical position. The dosing structure includes a dosing tank 3 for storing liquid or solid slow-release agents and at least one perforated pipe 2. One end of the perforated pipe 2 is rotatably hinged to the support rod 1 via a bearing or bushing structure, while the other end extends laterally into the water body. Numerous tiny holes are uniformly drilled along the length of the perforated pipe 2. A filtration structure is directly fixed to the perforated pipe 2. A sludge collection structure is also directly fixed to the perforated pipe 2 and located near the filtration structure.

[0022] The purification device of this application can be powered by an external drive (such as a motor installed on the top of the support rod 1) or by the force of the water flow itself (such as a water wheel installed at the end of the perforated pipe 2). During operation, the perforated pipe 2 drives the filter structure and sludge collection structure on it to rotate slowly around the axis of the support rod 1. Simultaneously, the chemicals in the dosing tank 3 are continuously and evenly released into the surrounding water body through small holes in the perforated pipe 2 under the action of gravity or a micro-pump. The rotating filter structure performs physical filtration and biological purification of the water flow; the rotating sludge collection structure continuously intercepts and collects floating debris (such as leaves, plastic, etc.) from the water surface into its net.

[0023] The purification device of this application achieves a three-in-one integration of purification functions. Through a simple rotational motion, it simultaneously completes chemical dosing, water filtration, and floating debris collection, solving the problems of dispersed equipment and poor coordination in traditional methods. The rotational operation expands its effective range from a static point to a dynamic circular area, resulting in significantly higher treatment efficiency than static devices and effectively preventing filter clogging.

[0024] In some embodiments of this application, the structural arrangement of the perforated tube 2 described above has been optimized. Specifically, as follows: Figure 2 As shown, four perforated pipes 2 are provided. These four perforated pipes 2 are arranged at uniform intervals around the support rod 1 in the circumferential direction, forming a "windmill" or "cross" layout. Each perforated pipe 2 is provided with a set of filter structure and / or a set of slag collection structure.

[0025] The four perforated tubes 2 are connected to the drive mechanism via a common connector to ensure synchronous rotation. Its working principle is the same as in the above embodiment, but its operating range covers the entire area around the support rod 1.

[0026] The main advantages of this embodiment are force couple balance and omnidirectional coverage. The four symmetrically arranged perforated tubes 2 cancel each other out during rotation, resulting in extremely smooth operation of the entire device, reducing vibration and energy loss, and extending its service life. Simultaneously, the 360° layout maximizes the purification area of ​​the device, significantly increasing its processing capacity.

[0027] In a further embodiment of this application, the arrangement of the above-mentioned filter structure and slag collection structure has been optimized, specifically, as follows: Figure 2 As shown, of the four perforated pipes 2, two (opposite to each other) are equipped with only a filtration structure, while the other two (alternating with the former) are equipped with only a slag collection structure. From the top view of the device, the filtration and slag collection structures are arranged alternately circumferentially.

[0028] As the purification unit rotates, the water first encounters and passes through a slag-collecting structure specifically designed to intercept large floating debris, before flowing to a filtration structure dedicated to fine filtration. This forms a clearly defined "pretreatment-main treatment" production line.

[0029] This embodiment achieves functional zoning and streamlined operation. Through alternating layouts, direct impact and clogging of the filter structure by floating debris are effectively avoided, allowing each functional unit to perform at its optimal efficiency. This orderly purification path makes the water treatment process more scientific and efficient, extending the service life of the filter structure.

[0030] In some other embodiments of this application, this embodiment provides another arrangement structure in which a set of slag collection structures and a set of filter structures are fixed sequentially along the rotation direction (i.e., the circumferential direction) on one of the perforated pipes 2, and the slag collection structures are located on the water-facing side of the filter structures.

[0031] As the perforated pipe 2 rotates, the water flows sequentially through the scum collection structure and the filtration structure. The scum collection structure intercepts larger scum particles, and the water, having removed the large scum, passes through the scum collection structure and enters the filtration structure. This arrangement prevents larger scum particles from entering the filtration structure and causing blockages.

[0032] This arrangement is particularly suitable for waters with complex pollutant composition and a large amount of floating debris.

[0033] In some embodiments of this application, the above-described filtering structure is further specified. See also Figure 1 and 2 As shown, the filter structure includes a packing mesh box 6 made of corrosion-resistant metal mesh or engineering plastic mesh. The packing mesh box 6 is filled with a large amount of uniformly sized water purification ceramic granules 7.

[0034] The water purification ceramsite filler 7 has a porous structure and a huge specific surface area. When water flows through the rotating filler mesh box 6, on the one hand, suspended solids are physically intercepted; on the other hand, a large number of aerobic microbial biofilms are rapidly enriched and cultivated on the surface of the ceramsite. These microorganisms can decompose and absorb pollutants such as organic matter, ammonia nitrogen, and total phosphorus in the water, achieving biodegradation.

[0035] This embodiment organically combines physical filtration with biodegradation. Water purification ceramic particles, acting as a highly efficient biological carrier, transform the device from a simple physical sieving apparatus into a mobile "bioreactor" capable of degrading pollutants at their source, achieving a higher level of ecological restoration.

[0036] In some other embodiments of this application, the filter structure has been further optimized. Specifically, the packing mesh box 6 is made into a square box, and the water-facing end face of the box is designed as an inclined surface that slopes forward from the bottom to the top in the rotation direction of the perforated pipe 2.

[0037] As the device rotates, the forward-leaning ramp acts like a paddle or an airplane wing, exerting a force on the water flow. This force can be decomposed into a horizontal component (driving the device's rotation) and a vertical component. The vertical component drives the surface water downwards, while the bottom water is forced upwards to fill the gaps, thus strongly promoting vertical mixing and exchange of the water.

[0038] This design structure breaks down water stratification and promotes water exchange between upper and lower layers. In summer or still waters, temperature and dissolved oxygen stratification easily occur, leading to oxygen deficiency at the bottom and the release of pollutants from the sediment. This embodiment uses mechanical means to force vertical circulation, bringing dissolved oxygen from the surface to the bottom, improving the sediment environment, and simultaneously bringing nutrients from the bottom to the surface for algae to utilize, thus fully activating the aquatic ecosystem. This is a crucial step in achieving ecological restoration.

[0039] In a further embodiment of this application, this embodiment specifies the above-described slag collection structure. See also Figure 1 and 2 As shown, the slag collection structure includes a slag collection net 8. This slag collection net 8 has a wide collection opening. The opening direction of the collection opening is located on one side of the slag collection net 8 along the rotation direction of the perforated pipe 2. Furthermore, the upper edge of the collection opening remains above the water surface of the water to be treated, both when the device is stationary and during operation.

[0040] During rotation, the slag collection net 8, with its wide collection opening, faces the water flow and floating objects, sweeping the floating objects into the net like a broom. Because the upper edge of the collection opening is above the water surface, even when the water flow is fluctuating or the device accelerates, the collected floating objects are unlikely to overflow from above.

[0041] This embodiment ensures efficient collection and effective containment. The directional collection port ensures extremely high interception efficiency; while the design above the water surface acts like an overflow preventer for the net, ensuring that the collected pollutants are not lost due to movement, making it particularly suitable for windy and wave-prone environments or scenarios requiring long-term unattended operation.

[0042] In some preferred embodiments of this application, the above-described dosing system is optimized. See also Figure 1As shown, the dosing tank 3 is fixedly installed at the upper end of the support rod 1 above the water surface. The bottom of the dosing tank 3 is connected to the inlet of all the perforated pipes 2 via a main delivery pipe 4. A speed control valve 5, which can be adjusted manually or electrically, is installed on the main delivery pipe 4.

[0043] Operators can control the flow rate of the chemical solution into the perforated pipe 2 by adjusting the opening of the speed regulating valve 5, based on water quality test reports (such as algae density and total phosphorus concentration), thereby achieving precise control of the dosing rate. The elevated dosing tank 3 utilizes gravity flow, reducing energy consumption.

[0044] This embodiment achieves centralized management and precise dosing. Placing the dosing tank 3 above the water surface facilitates observation and dosing operations. A single speed control valve 5 centrally controls the dosing amount of all perforated pipes 2, making the system simple and reliable. The precise dosing capability avoids pesticide waste and prevents secondary pollution that may result from overdosing, meeting the requirements of environmental friendliness and cost control.

[0045] like Figure 2 As shown, the axial direction in this application refers to the direction perpendicular to the paper, and the circumferential direction refers to... Figure 2 The circumferential direction centered on support rod 1.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
