Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, specifically to a device for treating cyanobacterial blooms. Background Technology
[0002] Cyanobacterial blooms are an ecological phenomenon in freshwater bodies caused by the massive proliferation of cyanobacteria. They severely damage the aquatic ecosystem, affect the landscape, and may release toxins, threatening the safety of drinking water for humans and livestock. Currently, methods for controlling cyanobacterial blooms include physical removal, chemical algae control, and biological regulation. Among these, physical removal methods are widely used due to their advantages of no secondary pollution and rapid effectiveness.
[0003] However, existing cyanobacteria harvesting devices mostly adopt fixed or ship-mounted filtration and collection structures, which result in high water content in the collected algae slurry, easy clogging of filter components, low harvesting efficiency and poor effect of cyanobacteria blooms. This solution addresses this technical problem. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a cyanobacterial bloom treatment device. Through continuous filtration and conveying of the inclined filter cloth, clogging is effectively avoided, ensuring continuous and efficient treatment. The cyanobacterial bloom removal effect is good. The treated water is discharged directionally from the stern of the ship using a gas-liquid mixing pump, which not only prevents interference with untreated areas, but also helps to improve the aquatic ecological environment by creating an oxygenated water flow. The cyanobacterial bloom removal efficiency is high.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cyanobacterial bloom treatment device, including a hull, and further including a filtration mechanism, a collection mechanism and a drainage mechanism sequentially arranged in the hull. A water inlet is provided on the front side of the hull. The filtration mechanism is used to filter cyanobacterial blooms from the water inlet. The collection mechanism is used to collect the filtered cyanobacterial blooms. The drainage mechanism is used to discharge water from the hull to the stern. The drainage mechanism includes a gas-liquid mixing pump arranged on the hull, a connecting pipe I connected at one end to the gas-liquid mixing pump, and a connecting pipe II connected at one end to the gas-liquid mixing pump. The other end of the connecting pipe I extends to the inner side of the stern of the hull. The connecting pipe II is arranged on the outer side of the stern of the hull. An air inlet pipe is provided on the side of the connecting pipe I.
[0006] The filtration mechanism includes an active roller and a driven roller rotatably disposed within the hull, a filter cloth tensioned between the active roller and the driven roller, and a motor connected to the active roller. The filter cloth is inclined toward the inlet and disposed on the inner side of the hull. One edge of the filter cloth is disposed at the bottom of the hull, and the other edge of the filter cloth is connected to the collection mechanism.
[0007] The collection mechanism includes a collection trough disposed in the hull and a collection roller rotatably disposed on the side of the collection trough. A feed inlet is provided on one side of the collection trough, and the filter cloth is in close contact with the bottom edge of the feed inlet side of the collection trough. A scraper for scraping off blue-green algae blooms in the collection trough is provided on the outside of the collection roller.
[0008] One end of the drive roller is provided with a drive gear, and one end of the collecting roller is provided with a driven gear. The drive gear meshes with the driven gear.
[0009] The bottom plate of the collection tank is provided with several filter holes.
[0010] A water collection tank is provided at the bottom of the hull, and the other end of the connecting pipe is connected to the water collection tank.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] (1) By continuously filtering and conveying the inclined filter cloth, clogging is effectively avoided, ensuring continuous and efficient treatment. The dredging effect of cyanobacterial blooms is good. The treated water is discharged from the stern of the ship by using a gas-liquid mixing pump, which not only prevents interference to the untreated area, but also helps to improve the aquatic ecological environment. The dredging efficiency of cyanobacterial blooms is high.
[0013] (2) Through the combination of the collection tank, the collection roller and the scraper, the centralized and automatic collection of cyanobacteria is realized. The filter holes at the bottom of the collection tank can effectively drain water, reduce the water content of the algal slurry, reduce the burden on subsequent transportation and treatment, and further improve the treatment efficiency of cyanobacterial blooms.
[0014] (3) The filtration and collection mechanisms are linked by a gear set, making the equipment structure more compact and the operation more reliable. The entire device is integrated into the hull, realizing the integrated automated operation of cyanobacteria harvesting, transportation, collection, dehydration and drainage, improving the efficiency and convenience of operation.

[0020] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0021] See Figures 1-4 A cyanobacterial bloom treatment device includes a hull 1, and further includes a filtration mechanism 2, a collection mechanism 3, and a drainage mechanism 4 sequentially arranged within the hull 1. An inlet 11 is provided on the front side of the hull 1. The filtration mechanism 2 is used to filter cyanobacterial blooms from the inlet 11. The collection mechanism 3 is used to collect the filtered cyanobacterial blooms. The drainage mechanism 4 is used to discharge water from the hull 1 to the stern. The drainage mechanism 4 includes a gas-liquid mixing pump 41 mounted on the hull 1, a connecting pipe 42 connected at one end to the gas-liquid mixing pump 41, and a connecting pipe 43 connected at one end to the gas-liquid mixing pump 41. The other end of the connecting pipe 42 extends to the inner side of the stern of the hull 1, and the connecting pipe 43 is located on the outer side of the stern of the hull 1. An air inlet pipe 44 is provided on the side of the connecting pipe 42.
[0022] The filtration mechanism 2 includes an active roller 21 and a driven roller 22 rotatably disposed within the hull 1, a filter cloth 23 tensioned between the active roller 21 and the driven roller 22, and a motor 24 connected to the active roller 21. The filter cloth 23 is inclined toward the inlet 11 and disposed on the inner side of the hull 1. One edge of the filter cloth 23 is disposed at the bottom of the hull 1, and the other edge of the filter cloth 23 is connected to the collection mechanism 3.
[0023] The collection mechanism 3 includes a collection trough 31 disposed inside the hull 1 and a collection roller 32 rotatably disposed on the side of the collection trough 31. A feed inlet is provided on one side of the collection trough 31. The filter cloth 23 is in close contact with the bottom edge of the feed inlet side of the collection trough 31. A scraper 33 for scraping out blue-green algae blooms in the collection trough 31 is provided on the outer side of the collection roller 32.
[0024] One end of the drive roller 21 is provided with a drive gear 211, and one end of the collecting roller 32 is provided with a driven gear 321. The drive gear 211 meshes with the driven gear 321.
[0025] The bottom plate of the collection tank 31 is provided with a number of filter holes 311.
[0026] A water collection tank 12 is provided at the bottom of the hull 1, and the other end of the connecting pipe 42 is connected to the water collection tank 12.
[0027] The specific working process of this utility model:
[0028] When in use, after the device is started, the motor 24 operates, driving the drive roller 21 to rotate, thereby causing the filter cloth 23 to move in a cycle. At the same time, through the meshing of the drive gear 211 and the driven gear 321, the collecting roller 32 is driven to rotate synchronously.
[0029] As the vessel 1 moves forward in the water, water containing cyanobacteria enters through the inlet 11, impacting the inclined filter cloth 23. The water passes through the mesh of the filter cloth 23, while suspended matter such as cyanobacteria is trapped on its surface. As the filter cloth 23 moves upward, the trapped cyanobacteria are carried to the inlet of the collection mechanism 3 and detach under gravity or inertia, falling into the collection tank 31. Some cyanobacteria may adhere to the rotating collection roller 32 and be scraped off by the scraper 33, falling into the collection tank 31. The algae slurry is left to stand or slightly agitated in the collection tank 31, and some water is drained through the filter holes 311, flowing into the bottom collection tank 12.
[0030] The gas-liquid mixing pump 41 operates, drawing filtered water from the collection tank 12 through connecting pipe 42. During the drawing process, air is drawn in through the air inlet pipe 44, forming a gas-liquid mixture inside the pump. This gas-liquid mixture is then sprayed at high speed towards the rear of the hull 1 through connecting pipe 43. This process not only discharges the treated water, preventing recirculation and pollution, but also provides thrust to assist the hull 1 in forward movement. Simultaneously, the air bubbles help increase dissolved oxygen in the local water, further reducing the risk of blue-green algae blooms.
[0031] Through continuous filtration and conveying by the inclined filter cloth 23, clogging is effectively avoided, ensuring continuous and efficient treatment. The cyanobacterial bloom removal effect is good. The gas-liquid mixing pump 41 is used to discharge the treated water directionally from the stern, which not only prevents interference with the untreated area, but also helps to improve the aquatic ecological environment by forming an oxygenated water flow. The cyanobacterial bloom removal efficiency is high.
[0032] The collection tank 31, collection roller 32 and scraper 33 work together to achieve centralized and automatic collection of cyanobacteria. The filter holes 311 at the bottom of the collection tank 31 can effectively drain water, reduce the water content of the algal slurry, reduce the burden on subsequent transportation and treatment, and further improve the treatment efficiency of cyanobacterial blooms.
[0033] The filtration mechanism 2 and the collection mechanism 3 are linked by a gear set, resulting in a more compact equipment structure and more reliable operation. The entire device is integrated into the hull 1, realizing the integrated automated operation of cyanobacteria harvesting, transportation, collection, dehydration, and drainage, thus improving operational efficiency and convenience.
[0034] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
