Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a device for purifying eutrophic water bodies. Background Technology

[0002] Eutrophication is a water pollution phenomenon caused by excessive levels of plant nutrients such as nitrogen and phosphorus. When water bodies are eutrophic, aquatic organisms, especially algae, proliferate rapidly, altering the biomass, species diversity, and quantity, thus disrupting the ecological balance of the water body. Therefore, it is necessary to treat algae and other aquatic organisms in eutrophic water bodies.

[0003] The current treatment methods mainly involve dredging and filtration. However, these methods have limited filtration capacity for algae, and the separated algae have a high water content, making them unsuitable for subsequent recycling. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as limited filtration capacity for algae and high water content in the separated algae, which makes subsequent recycling inconvenient. Therefore, this invention proposes a eutrophic water purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A eutrophic water purification device includes a treatment tank, with multiple water inlets through the middle of the top wall of the treatment tank, a material collection hopper and a material outlet at the bottom of the treatment tank, and a separation mechanism inside the treatment tank.

[0007] The separation mechanism includes a separation disc fixedly mounted on the inner wall of the processing tank by a mounting bracket, multiple feeding blades rotatably arranged in the separation disc, a main shaft vertically arranged in the middle of the separation disc and fixedly connected to the feeding blades, and a drive assembly for driving the main shaft to rotate, which is arranged on the top wall of the processing tank.

[0008] The separating disc includes a filter screen and a protective ring on the outside of the filter screen. The filter screen has a material leakage port between the edge of the feeding blade and the protective ring. A water collection hopper and a drain outlet are provided below the filter screen.

[0009] Preferably, the separation mechanism is provided with multiple stacked separation discs, each of which is provided with corresponding material feeding blades. The main shaft passes through the multiple separation discs and is fixedly connected to the multiple layers of material feeding blades. One end of the drain pipe is connected to the drain outlet of the lowest water collection hopper, and the other end of the drain pipe passes through the side wall of the treatment tank and extends to the outside of the treatment tank.

[0010] More preferably, a stabilizing sleeve is provided in the middle of the upper separation disc corresponding to the main shaft, and a protective cover is provided on the main shaft above the stabilizing sleeve. The protective cover is rotatably connected to the outside of the stabilizing sleeve and fixedly connected to the feeding blade.

[0011] More preferably, the lower end of the upper separating disc is connected to a funnel-shaped guide ring, the upper end of which is positioned inside the discharge port and the lower end of which is positioned outside the lower protective ring, for guiding the material leaking from the discharge port into the collection hopper.

[0012] Preferably, the filter screen is in the shape of an inverted frustum.

[0013] More preferably, the feeding blade is arc-shaped, and the lower end of the feeding blade is attached to the filter screen.

[0014] Preferably, the drive assembly is provided with a motor and a reducer for driving the spindle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the design of a multi-layer separation disc is used to fully separate algae such as cyanobacteria in eutrophic water bodies, so as to ensure a good treatment effect on eutrophic water bodies.

[0017] 2. In this utility model, the arc-shaped design of the filter screen allows the water to flow naturally towards the center of the filter screen, and the material-dispensing blades push the solid algae outwards to achieve a good separation effect of algae and also effectively reduce the water content of the algae material, which is convenient for subsequent processing.

[0018] 3. In this utility model, the design of the water collection hopper allows the water falling from the upper layer to gather in the middle of the lower filter screen, ensuring sufficient filtration of the water. After filtration, the water is discharged through the drain pipe, and the algae are stored separately through the collection hopper for convenient subsequent processing.

[0019] This utility model features a novel design and simple structure. It can be mounted on a ship for mobile processing, ensuring the complete separation of cyanobacteria from the water and reducing the water content of the separated algae, facilitating subsequent recycling and making it suitable for widespread use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-6 A eutrophic water purification device includes a treatment tank 1. The top wall of the treatment tank 1 has multiple inlets 13 that extend through the middle. The lower part of the treatment tank 1 is provided with a collection hopper 11 and a discharge port 12. The treatment tank 1 is equipped with a separation mechanism 2. Eutrophic water is sent into the treatment tank 1 through the inlets 13. The separation mechanism 2 is used to separate cyanobacteria and other algae in the eutrophic water. The separated cyanobacteria and other algae are sent out through the discharge port 12.

[0029] The separation mechanism 2 includes a separation disc 21 fixedly mounted on the inner wall of the treatment tank 1 via a mounting bracket 22, a plurality of feeding blades 24 rotatably arranged in the separation disc 21, a main shaft 25 vertically arranged in the middle of the separation disc 21 and fixedly connected to the feeding blades 24, and a drive assembly 26 arranged on the top wall of the treatment tank 1 for driving the main shaft 25 to rotate; water is fed into the separation disc 21 through the water inlet 13, and the feeding blades 24 are driven to rotate by the drive assembly 26 to separate algae in the water.

[0030] The separation disc 21 includes a filter screen 212 and a protective ring 211 disposed on the outer side of the filter screen 212. A material leakage port 23 is provided between the edge of the material-dispensing blade 24 and the protective ring 211 on the filter screen 212. A water collection hopper 28 and a drain outlet are provided below the filter screen 212. During algae separation, the material-dispensing blade 24 moves the algae filtered through the filter screen 212 outwards until the material passes through the leakage port 23 and is fed into the collection hopper 11 for subsequent discharge. The separated water leaks through the filter screen 212, is collected by the water collection hopper 28, and is discharged through the drain outlet.

[0031] Based on the above technical solution, when treating eutrophic water bodies, this device can be installed on the hull of a ship to treat the water body in a mobile manner. During treatment, a water pump or other ship-mounted device is used to send the water body into the separation mechanism 2 through the inlet 13. The algae in the water body are filtered through the filter screen 212. The filtered water body falls into the water collection hopper 28 and is collected and sent out through the drain pipe 29. The algae that are filtered out are moved to the outside by the pusher blades 24 until they fall into the collection hopper 11 through the discharge port 23 for collection, which is convenient for subsequent treatment.

[0032] In this technical solution, such as Figure 1-6 As shown, the separation mechanism 2 has multiple stacked separation discs 21, each with corresponding feeding blades 24. The main shaft 25 passes through the multiple separation discs 21 and is fixedly connected to the multi-layer feeding blades 24. One end of the drain pipe 29 is connected to the drain outlet of the lowest water collection hopper 28, and the other end of the drain pipe 29 extends through the side wall of the treatment tank 1 to the outside of the treatment tank 1. The design of the multi-layer separation discs 21 ensures sufficient filtration of algae, and the multi-layer feeding blades 24 are driven by the same main shaft 25 passing through the multi-layer separation discs 21, which is convenient and simplifies the drive structure. The water collection hopper 28 located below the upper filter screen 212 can guide the falling water to the middle of the filter screen 212 to ensure sufficient filtration of the water by the lower filter screen 212. This prevents water falling from the outside of the filter screen 212 from entering the collection hopper 11 through the leakage port 23, which would increase the water content in the material, making subsequent processing difficult and reducing the capacity for loading and storing algae.

[0033] In this technical solution, such as Figure 1-3 As shown, a stabilizing sleeve 251 is provided in the middle of the upper separating disc 21 corresponding to the main shaft 25. A protective cover 241 is provided on the main shaft 25 above the stabilizing sleeve 251. The protective cover 241 is rotatably connected to the outside of the stabilizing sleeve 251 and fixedly connected to the feeding blade 24. The stabilizing sleeve 251 ensures the stable rotation of the main shaft 25. In conjunction with the design of the protective cover 241, the stabilizing sleeve 251 prevents water from entering between the stabilizing sleeve 251 and the main shaft 25, ensuring the stable rotation of the main shaft 25 and avoiding frequent maintenance.

[0034] In this technical solution, such as Figure 1-6 As shown, the lower end of the upper separating disc 21 is connected to a funnel-shaped guide ring 27. The upper end of the guide ring 27 is positioned inside the discharge port 23, and the lower end is positioned outside the lower protective ring 211. This guide ring 27 is used to guide the material leaking from the discharge port 23 into the collection hopper 11. Through the design of the guide ring 27, the material filtered by the upper separating disc 21 is directly fed into the collection hopper 11, facilitating material collection.

[0035] In this technical solution, such as Figure 1-6 As shown, the filter screen 212 is in the shape of an inverted frustum. This inverted frustum design makes the filter screen 212 resemble a bowl bottom. When the feeding blades 24 move the material outwards, the water in the algae naturally flows towards the center of the filter screen 212, preventing water from entering the collection hopper 11 through the discharge port 23 along with the algae. This reduces the moisture content of the algae material and facilitates subsequent processing.

[0036] In this technical solution, such as Figure 1-4 As shown, the feeding blade 24 is arc-shaped, and its lower end is attached to the filter screen 212. The arc-shaped feeding blade 24 supports the cyanobacteria when they are being agitated, preventing them from slipping into the center of the filter screen 212 and ensuring effective agitation and discharge of the cyanobacteria.

[0037] In this technical solution, such as Figure 1-3 As shown, the drive assembly 26 is equipped with a motor and a reducer for driving the main shaft 25. This ensures stable driving of the main shaft 25 and a stable stirring effect on the cyanobacteria.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
