Description

Technical Field

[0001] The present invention relates to the technical field of cyanobacterial bloom collection, and particularly to a fixed cyanobacterial bloom collector. Background Art

[0002] Cyanobacterial blooms caused by water eutrophication have become a major environmental problem globally and have received extensive attention from countries around the world. Most bloom-forming cyanobacteria produce toxins, threatening the safety of water supply. Cyanobacterial blooms also damage the water ecosystem, change the structure of biological communities, and reduce biodiversity. In addition, the outbreak of cyanobacterial blooms severely restricts the regional economic and social development. Mechanical algae removal is currently the most common and mature emergency method, which solves the "apparent algal bloom" and reduces secondary disasters by salvaging the cyanobacteria accumulated in the aggregation area. Currently, cyanobacteria salvage equipment across the country mainly includes two categories: one is a fixed suction trap, and the other is a shipborne suction device. The fixed suction trap is mainly for waters with severe cyanobacterial blooms existing for a long time, and the shipborne suction device is mainly for non-fixed waters. The existing fixed traps have low construction costs, but the control range is limited, and the water pump suction is likely to damage the floating state of cyanobacterial blooms, increasing difficulties for subsequent dehydration processes. Therefore, the present invention proposes a fixed cyanobacterial bloom collector to solve the problems existing in the prior art. Summary of the Invention

[0003] Aiming at the above problems, the purpose of the present invention is to propose a fixed cyanobacterial bloom collector, which has the advantage of improving the collection efficiency and can solve the problems existing in the prior art.

[0004] To achieve the purpose of the present invention, the present invention is realized through the following technical solutions: A fixed cyanobacterial bloom collector includes a collector housing. An algae inlet is provided on the collector housing, and a wire mesh is installed inside the collector housing. An inclined sieve filter is arranged above the wire mesh, and the inclined sieve filter is fixedly connected to the collector housing. A collection assembly is installed on the outer side of the collector housing. A drainage trough is installed at the bottom of the collector housing, and a water inlet is provided on the drainage trough. A submersible agitator is installed inside the drainage trough. A first drain pipe is installed on the collector housing, and the first drain pipe communicates with the inner cavity of the drainage trough. An air flotation assembly is installed between the drainage trough and the wire mesh.

[0005] Further improvement lies in that: The inclined sieve filter includes two groups of symmetrically arranged fixing plates. A conveyor belt type filter screen is installed between the two groups of fixing plates. A rotating roller is arranged inside the conveyor belt type filter screen, and both ends of the rotating roller shaft are connected to the fixing plates through bearings. A number of groups of rotating rollers are provided, and the number of groups of rotating rollers is driven by a reduction motor.

[0006] A further improvement is that the flotation assembly includes a delivery pipe, the delivery pipe is provided with several groups, and the delivery pipe is connected to the collector shell through a sealing connector, one end of the several groups of delivery pipes is connected through a diversion pipe, and a columnar bubble generator is installed on the delivery pipe, and the columnar bubble generator is evenly provided with several groups.

[0007] A further improvement is that the collecting assembly comprises an outer body, an inner body is placed inside the outer body, a handle is installed on the inner body, the bottom of the inner body is a mesh design, and a drainage connection port is provided on the outer body.

[0008] A further improvement is that a scraper is provided below the inclined screen filter, both ends of the scraper are connected to fixed plates at corresponding positions through fixing parts, the scraper contacts the surface of the conveyor belt filter screen, and the position of the fixed plate corresponds to the collecting assembly.

[0009] A further improvement is that an extension hose is installed on the first drain pipe, a floating hose is installed on one end of the extension hose away from the first drain pipe, a drain port is provided on the floating hose, and the drain port faces the collector shell, and the drain port is provided in several groups.

[0010] A further improvement is that: the water inlets are evenly arranged in a plurality of groups, and a filter screen is installed on the inner side of the water inlet.

[0011] A further improvement is that the diverter pipe is connected to an external compressed air supply device through a pipeline.

[0012] The beneficial effects of the present invention are:

[0013] (1) The present invention has a simple overall structure and is easy to use. Through the design of the algae inlet, the algae blooms floating on the water surface always enter the collection bin, which reduces the water treatment volume compared to water pump suction and does not destroy the floating state of the algae in the collection bin.

[0014] (2) The present invention improves the algae-water separation efficiency in the collector shell by combining flotation and an inclined screen filter, simplifies the operation process, reduces dependence on the operating environment, improves the operating stability of the equipment, and significantly reduces maintenance costs and work intensity, thereby ensuring the high efficiency and sustainability of the device in long-term operation.

[0015] (3) The water flow discharged through the floating hose can form a water flow in the target area between the floating hose and the collector shell, thereby utilizing the bottom clean water as return water to push the cyanobacteria bloom in the water toward the collector shell, effectively increasing the concentration of the cyanobacteria bloom and improving the cyanobacteria collection efficiency in the salvage area.

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0023] According to Figures 1-5 As shown, this embodiment provides a fixed blue-green algae bloom collector, including a collector housing 1, an algae inlet 2 is provided on the collector housing 1, and a wire mesh 3 is installed inside the collector housing 1. The algae inlet 2 has a certain length to ensure smooth water flow, and the wire mesh 3 makes the upper layer of water flow evenly downward, avoiding the appearance of eddies and destroying the floating state of the blue-green algae bloom inside the collector housing 1.

[0024] Above the wire mesh 3, there is an inclined sieve filter 4, and the inclined sieve filter 4 is fixedly connected to the collector housing 1. One end of the inclined sieve filter 4 is located inside the collector housing 1, and the other end is located above the collector housing 1. Therefore, there is an opening above the collector housing 1 for the inclined sieve filter 4 to pass through. When external water with cyanobacterial blooms enters, since the cyanobacterial blooms are in a floating state in the water, the water flow pushes the cyanobacteria towards the inclined sieve filter 4, and then the inclined sieve filter 4 filters and conveys them. Specifically, the inclined sieve filter 4 includes two sets of symmetrically arranged fixing plates 9, and the fixing plates 9 are fixedly connected to the inner wall of the collector housing 1. Correspondingly, a conveyor belt type filter screen 10 is installed between the two sets of fixing plates 9. Inside the conveyor belt type filter screen 10, there are rotating rollers 11, and both ends of the axis of the rotating roller 11 are connected to the fixing plates 9 through bearings. There are several sets of rotating rollers 11, and several sets of rotating rollers 11 are driven by a reduction motor 12. Further, between several sets of rotating rollers 11, they are interconnected through the cooperation of sprockets and chains. This chain system ensures that all rotating rollers operate together at the same speed, avoiding the phenomenon of out-of-step of any set of rollers, so as to ensure the uniform movement of the screen. And the uppermost rotating roller 11 is driven by the reduction motor 12. Therefore, the reduction motor 12 is located above the collector housing 1 and is fixedly connected to the fixing plate 9 through a bracket. Thus, it drives the conveyor belt type filter screen 10 to rotate in a cycle, and thereby conveys the contacted cyanobacteria into the subsequent collection assembly.

[0025] Further, below the inclined sieve filter 4, there is a scraper 19. Both ends of the scraper 19 are connected to the corresponding fixing plates 9 through fixing parts. The scraper 19 is in contact with the surface of the conveyor belt type filter screen 10, and the position of the fixing plate 9 corresponds to the collection assembly. The function of the scraper 19 is to scrape off the cyanobacterial blooms attached to the surface of the conveyor belt type filter screen 10. And its position corresponding to the collection assembly is to ensure that the cyanobacterial blooms cleared by the scraper 19 can be effectively sent into the collection area, and at the same time, it can also avoid the situation that the conveyor belt type filter screen 10 is blocked due to sediment accumulation.

[0026] Further, a collection assembly is installed on the outer side of the collector housing 1. The collection assembly includes an outer bladder body 16. An inner bladder body 17 is placed inside the outer bladder body 16, and a handle is installed on the inner bladder body 17. The bottom of the inner bladder body 17 is of a mesh design and is the actual collection container for cyanobacterial blooms. A drainage connection port 18 is provided on the outer bladder body 16. The inner bladder body 17 is directly placed inside the outer bladder body 16. An outer edge portion is provided at the upper end of the inner bladder body 17, which contacts the upper end of the outer bladder body 16 and plays a limiting role. Then, with the help of the handle, it is convenient for personnel to take out the inner bladder body 17, thus facilitating the treatment of the collected cyanobacterial blooms. The mesh design of the inner bladder body 17 plays the role of a filter, and the filtered water is located inside the outer bladder body 16 (there is a water storage cavity between the bottom of the inner bladder body 17 and the bottom inside the outer bladder body 16), and then it is connected to an external drainage pipe through the drainage connection port 18 to facilitate the discharge of water.

[0027] A drainage trough 5 is installed at the bottom of the collector housing 1, and a water inlet 6 is provided on the drainage trough 5. A number of groups of water inlets 6 are evenly provided, and a filter screen is installed inside the water inlet 6. In this embodiment, four groups of water inlets 6 are evenly provided, which are respectively on the upper side, front side, rear side, and right side (the side away from the first drainage pipe 8) of the drainage trough 5. By providing the water inlet 6, it is ensured that the water flows evenly into the drainage trough 5, thus avoiding the retention or vortex phenomenon caused by uneven water flow. A submersible agitator 7 is installed inside the drainage trough 5. A first drainage pipe 8 is installed on the collector housing 1, and the first drainage pipe 8 communicates with the inner cavity of the drainage trough 5. Further, an extension hose 20 is installed on the first drainage pipe 8, and one end of the extension hose 20 away from the first drainage pipe 8 is installed with a floating hose 21. A drainage port is provided on the floating hose 21, and the drainage port faces the collector housing 1. A number of groups of drainage ports are provided. By providing the submersible agitator 7, the water inside the collector housing 1 enters the first drainage pipe 8, then enters the floating hose 21 through the extension hose 20, and is discharged through the drainage port. Since the position of the collector housing 1 of this device is fixed, the floating hose 21 is arranged in an external river. The water discharged through it drives the cyanobacterial blooms in the target area (i.e., the area between the floating hose 21 and the collection shell 21) to converge towards the collector housing 1, thereby improving the collection efficiency of cyanobacterial blooms.

[0028] An air flotation assembly is installed between the drainage trough 5 and the wire mesh 3. The air flotation assembly includes a delivery pipe 13. There are several groups of the delivery pipes 13, and the delivery pipes 13 are connected to the collector housing 1 through sealing connectors. In this embodiment, three groups of the delivery pipes 13 are evenly arranged. At the same time, one end of the delivery pipe 13 passes through the collector housing 1 and is located outside the collector housing 1. One ends of the three groups of delivery pipes 13 are connected through a shunt pipe 14. A columnar bubble generator 15 is installed on the delivery pipe 13, and several groups of the columnar bubble generators 15 are evenly arranged. Correspondingly, the shunt pipe 14 is connected to an external compressed air supply device through a pipeline. During operation, the external compressed air supply device transports compressed air into the three groups of delivery pipes 13 through the shunt pipe 14, and then forms bubbles through the columnar bubble generators 15. These bubbles rise to the water surface, and then promote the flow of water through the bubbles, enhance the aggregation effect of cyanobacteria, and improve the collection efficiency of cyanobacterial blooms.
