Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a stratified purification device for water bodies used in river ecological restoration. Background Technology

[0002] With rapid industrialization and urbanization, many rivers have become polluted to varying degrees, damaging aquatic ecosystems. To improve water quality and restore the self-purification capacity of rivers, directly installing in-situ water purification devices in the river channel has become a common and effective technical approach. These devices are typically submerged in water and purify the flowing river water through physical interception, adsorption by packing materials, and microbial degradation.

[0003] During the long-term operation of these in-situ purification devices, the external grilles or filters inevitably intercept a large amount of aquatic plants, leaves, and various floating debris. Over time, these deposits gradually accumulate and clog the grilles, significantly reducing the water flow rate and severely impacting the processing efficiency of subsequent purification units, even causing the entire device to malfunction. Therefore, regular cleaning of the grilles is a necessary maintenance procedure to ensure the normal operation of the device.

[0004] However, for most existing integrated river purification devices, convenient online maintenance mechanisms are typically lacking, whether for cleaning externally clogged screens or replacing internally faulty packing. The only solution is often to use hoisting equipment to lift the entire heavy, water-filled device from the river to the bank or a workboat, perform maintenance, and then hoist it back into place. This process is not only cumbersome and time-consuming, but also requires specialized machinery and personnel, leading to high costs and difficulties in daily maintenance, thus limiting the widespread application and long-term operation of such devices.

[0005] Therefore, this utility model proposes a stratified purification device for river ecological restoration water bodies to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a stratified purification device for river ecological restoration water bodies, aiming to improve the problems of existing technologies where the external bar is difficult to clean online after clogging, and the internal purification filler must be replaced by hoisting the entire device out of the water, resulting in cumbersome and laborious maintenance processes and high maintenance costs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a stratified purification device for water bodies used in river ecological restoration, comprising: a frame and a stratified frame, wherein the stratified frame is pluggably installed inside the frame, and also includes a scraper; The scraper includes a handle and a sliding block, the sliding block being fitted into a guide rail on the frame. A grid is fixedly connected to the outer wall of the frame by bolts. The scraper is slidably connected to the outer side of the frame and can reciprocate along the outer surface of the frame. The side of the layered frame can be pulled out horizontally from the frame. A handle is fixedly connected to the outer end face of the layered frame and is detachably locked to the frame by a limiting rod.

[0008] Preferably, the scraper is slidably connected to the frame and closely adheres to the surface of the grille for effective scraping and cleaning.

[0009] Preferably, the scraper includes a handle and a sliding block, the sliding block being fitted into a guide rail on the frame to achieve stable sliding guidance.

[0010] Preferably, the inner wall of the frame is provided with a horizontal slide rail corresponding to the position of the layered frame, and the layered frame slides into the horizontal slide rail to facilitate its smooth horizontal pulling and pushing.

[0011] Preferably, the interior of the layered frame has a layered cavity for filling with purification material.

[0012] Preferably, the river ecological restoration water body stratified purification device further includes an aeration pump, which is installed at the bottom of the frame and is used to supplement oxygen to the water body.

[0013] Preferably, the river ecological restoration water body stratified purification device further includes anchor rods, which are fixedly connected to the frame to fix the entire device in the riverbed.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a scraper that can slide along its surface and fit against the grid outside the frame, the problem of the prior art that the filter screen of the purification device must be hoisted out of the water surface for cleaning after it is clogged is solved, which leads to cumbersome operation and high cost. The grid can be cleaned online and quickly without moving the main body of the device, which significantly simplifies the maintenance process.

[0015] 2. This utility model solves the problem in the prior art that when the internal purification packing needs to be replaced, the bulky device still needs to be retrieved as a whole, which leads to time-consuming and labor-intensive maintenance work. By designing the layered frame to be able to be pulled out horizontally from the side of the frame, and setting a handle for pulling and a limit rod for locking, this utility model achieves the effect of independently and quickly replacing or maintaining any purification module, realizing convenient modular management and greatly improving maintenance efficiency.

[0018] 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.

[0019] Reference Figures 1-5 This utility model provides a stratified purification device for water bodies used in river ecological restoration, which aims to solve the technical problems of existing in-situ river purification devices, such as the solidification of the structure, which leads to filter clogging and the need for maintenance operations such as cleaning and replacing internal fillers, which require overall hoisting, resulting in cumbersome operation procedures and high maintenance costs.

[0020] Specifically, it includes a frame 1 and a layered frame 5 that can be plugged into the frame 1. The frame 1 serves as the main support and installation platform for the entire device, providing a foundation for the connection and fixation of all other components. The layered frame 5 serves as the core purification function carrier, and its interior is used to accommodate various water treatment purification materials.

[0021] It also includes a scraper 3, which has a handle 301 for the operator to hold and a sliding block 302 for guiding the sliding. A grid 101 for preliminary filtration is fixedly connected to the outer wall of the frame 1 by bolts 102. At the same time, the sliding block 302 is embedded in the guide rail opened on the frame 1. Through the sliding connection between the sliding block 302 and the guide rail, the scraper 3 can move back and forth stably along the outer surface of the frame 1, so that the operator can scrape and clean the debris attached to the surface of the grid 101 by operating the scraper 3.

[0022] The layered frame 5 is designed to be pulled out horizontally from the frame 1. To facilitate the pulling operation, a handle 501 is fixedly connected to the outer end face of the layered frame 5. When the layered frame 5 is fully pushed into the predetermined working position of the frame 1, the limiting rod 502 passes through the pre-set alignment hole on the layered frame 5 and the frame 1 to achieve a detachable locking between the layered frame 5 and the frame 1. This structural combination ensures that a single layered frame 5 can be taken out or put back independently without moving the entire device body.

[0023] To achieve primary filtration of the water flow, the grid 101 is fixedly connected to the outer wall of the frame 1, which is preferably a cube or cuboid structure. The grid 101 is correspondingly installed on the four vertical sides of the frame 1 and fastened by a plurality of bolts 102. This connection method not only ensures the stability of the structural connection, but also facilitates individual disassembly and replacement when the grid 101 is damaged. The mesh size of the grid 101 is selected according to the hydrological characteristics and main pollutant types of the target river to intercept larger floating and suspended objects such as leaves, plastic bags, and aquatic plants.

[0024] The scraper 3 is mounted on the frame 1 via a sliding connection, and the blade of the scraper 3 remains in close contact with the outer surface of the grid 101 throughout the entire sliding stroke. To achieve a stable fit, the guide rail on the frame 1, which guides the sliding block 302, maintains a precise parallel relationship with the surface of the grid 101 in terms of position and orientation. The blade of the scraper 3 has a certain rigidity to ensure that sufficient pressure can be generated during the up-and-down reciprocating motion, thereby effectively cutting and peeling off the aquatic plants, algae, and sticky sludge attached to the surface of the grid 101, and quickly restoring the water passage capacity of the grid 101.

[0025] To ensure that the layered frame 5 can be smoothly and steadily pulled out horizontally from the frame 1, a horizontal slide rail is provided on the inner wall of the frame 1 for each installation position of the layered frame 5. The horizontal slide rail is preferably an L-shaped or U-shaped guide rail extending in the horizontal direction, which is fixedly welded or bolted to the inner column or beam of the frame 1. The lower edge of the side wall of the layered frame 5 is provided with pulleys or wear-resistant sliders that match the horizontal slide rail. When it is necessary to pull out or push in the layered frame 5, the layered frame 5 can make a low-resistance linear movement under the guidance and support of the horizontal slide rail, avoiding jamming or tilting.

[0026] The layered frame 5 slides into the aforementioned horizontal slide rail via a matching structure on its side wall. This track-type matching structure not only provides precise guidance during the pulling process, but also, when the layered frame 5 is in the working position, the horizontal slide rail bears most of the weight of the layered frame 5 and its internal purification material, evenly transferring the load to the frame 1, thus ensuring the structural strength and long-term stability of the entire device.

[0027] To achieve deep water purification, the interior of the layered frame 5 is designed as a hollow structure, thus creating a layered cavity 503 for filling with purification material. The layered cavity 503 occupies the main internal space of the layered frame 5. The upper and lower surfaces of the layered frame 5, as well as the front and rear ends in the direction of water flow, are all designed as mesh plates or porous plates that allow water to pass through, so that the water can fully penetrate and contact the purification material filled in the layered cavity 503. Optional purification materials include, but are not limited to, quartz sand, activated carbon, zeolite, maifanite, microbial carrier filler, etc., and can be filled with a single type or multiple materials in layers as needed.

[0028] To enhance the biological purification capacity of the device and improve the aquatic ecological environment, the device also includes an aeration pump 4, which is preferably a waterproof submersible air pump installed at the bottom inside the frame 1. Specifically, it can be fixed to the bottom plate of the frame 1 or below the lowest layered frame 5. The air outlet of the aeration pump 4 is connected to an aeration disc or a perforated aeration pipe. The aeration pipe network is evenly distributed at the bottom of the device. After starting, it can generate a large number of fine bubbles. The bubbles pass through all the layered frames 5 from bottom to top, providing sufficient dissolved oxygen for the microorganisms attached to the packing material in the layered cavity 503, while disturbing the water and improving the mass transfer efficiency.

[0029] To ensure the stable operation of the entire device in the river, the device also includes anchor rods 2. There can be multiple anchor rods 2. One end of each anchor rod is fixedly connected to the side or bottom corner of the frame 1 by a flange and high-strength bolts. The other end is designed as a pointed cone structure that can be driven into the riverbed geology, or as a platform structure that can hold counterweights. Through the action of the anchor rods 2, the entire river ecological restoration water body stratification purification device is firmly fixed in the preset river position to resist the impact of water flow and buoyancy.

[0030] Working principle: In the initial installation stage, the entire device is fixed to the predetermined position in the river channel by anchor rods 2. The main body of the device is composed of frame 1. River water can flow freely through the grid 101 on the outside of frame 1. The grid 101 is fixed to frame 1 by bolts 102, intercepting larger suspended solids and floating garbage in the water flow, completing the initial physical filtration. The water that has passed through the initial filtration enters the interior of frame 1 and passes through multiple stacked layered frames 5 in sequence. The water flow is in full contact with the purification material filled in the layered cavity 503 inside the layered frame 5, realizing the adsorption, filtration and degradation of pollutants. At the same time, the aeration pump 4 installed at the bottom of frame 1 injects air into the water. The air bubbles pass through all the layered frames 5 from bottom to top, oxygenating the water and providing survival conditions for the microorganisms attached to the purification material.

[0031] When the surface of the bar screen 101 is affected by aquatic plants or dirt, thus affecting the water flow efficiency, the maintenance process begins. The operator does not need to retrieve the device from the water; they only need to hold the handle 301 of the scraper 3 and use the sliding block 302, which is embedded in the external guide rail of the frame 1, to guide the scraper 3 to move it back and forth along the outer surface of the bar screen 101. The blade of the scraper 3 is in close contact with the surface of the bar screen 101, thereby effectively cutting and peeling off the attached materials and quickly restoring the water flow function. Through the synergistic action of the scraper 3, the handle 301, and the sliding block 302, online cleaning of the bar screen 101 is achieved.

[0032] When it is necessary to replace or maintain the purification material in a certain layered frame 5, another maintenance process is initiated. The operator first pulls out the limiting rod 502 used to lock the layered frame 5, releasing it from the frame 1. Then, holding the handle 501 at the end of the layered frame 5, the operator pulls the layered frame 5 horizontally out from the side of the frame 1 along the horizontal slide rail set on the inner wall of the frame 1. After maintenance is completed, the layered frame 5 is pushed back to its original position along the horizontal slide rail, and the limiting rod 502 is reinserted to complete the locking. Through the structural cooperation of the handle 501, the limiting rod 502 and the horizontal slide rail inside the frame 1, the independent and quick disassembly and assembly of a single purification module is realized.
