Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, and in particular to an aquatic algae-water high-efficiency flotation separation platform. Background Art

[0002] Existing cyanobacteria treatment devices have exposed a series of problems that need to be solved when dealing with complex cyanobacteria pollution. In terms of functional design, most devices only focus on a single link, such as simple salvage or initial separation, and cannot form a comprehensive and coherent treatment process. This makes it difficult to cope with the different needs of each stage in the cyanobacteria treatment process in actual applications, resulting in a significant reduction in the treatment effect.

[0003] In terms of the treatment process, there is a lack of effective coordination and integration between the various links from algae water collection to the final tailwater discharge. Algae water collection equipment is often unable to adapt to different water environments and algae water distribution conditions, resulting in low collection efficiency and difficulty in ensuring that the collected algae water is representative. In the algae mud treatment and tailwater disposal links, due to the lack of integrated planning, problems such as incomplete treatment, waste of resources and secondary pollution often occur.

[0004] In summary, developing an efficient algae-water flotation separation platform on water that can overcome the above-mentioned problems and realize integrated and efficient operations from algae-water collection to tail water disposal has important practical significance for solving the problem of cyanobacteria pollution and protecting the ecological environment of water bodies.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Efficient algae-water separation and treatment: Through the synergistic effect of the flocculation stirring box, dissolved air mixing box and other components, the algae-water is efficiently separated to form algae slurry. The large number of micro-nano bubbles generated by the mixture of dissolved air water and algae-water can effectively improve the removal rate of blue algae and suspended solids in the water body, and the water purification effect is significant. At the same time, the spiral dehydrator further dehydrates the separated algae slurry, making the algae mud easy to store and subsequently dispose of. The entire treatment process is closely connected, greatly improving the treatment efficiency.

[0017] 2. Flexible adaptation to various working conditions: The design of the carrier enables the device to be flexibly moved in different waters and can quickly reach the blue algae outbreak area for treatment, effectively solving problems such as the difficulty of magnetic capture boats to move in nearshore waters. The main body of the air flotation device can be detached and installed on the carrier, and is equipped with hydraulic legs. It can not only operate on the water, but also be used alone on the shore and is convenient for leveling and transportation, adapting to a variety of operating scenarios and needs.

[0018] 3. Optimize the algae water collection process: The blue algae extraction pump is equipped with a lifting platform with a filter mesh, which can pre-filter large particles of impurities in the sucked algae water to avoid the impact of impurities on subsequent processing links. At the same time, the height of the lifting platform can be adjusted by the electric hoist, and the algae water concentration at different depths can be sucked, which effectively improves the algae water collection efficiency and reduces the empty pumping phenomenon. In addition, the remote control gathering boat pulls the blue algae enclosure to gather and enrich the blue algae, further enhancing the collection capacity of high-concentration algae water.

[0019] 4. Enhanced algae scraping function and cleaning maintenance: The algae scraping mechanism is driven by a rotating motor, which drives the scraper to move cyclically to scrape the algae, ensuring the continuous cleaning of floating blue algae. The unique automatic switching structure of the scraper can effectively reduce the space occupied in different positions, and automatically clean the residual blue algae on the surface with the help of the cleaner to prevent secondary pollution, thereby improving the reliability and sustainability of the algae scraping.

[0020] 5. Integrated multifunctional integration: It integrates multiple functions such as algae water extraction, cyanobacteria aggregation, flotation separation, sludge filtration, water carrier platform and power supply system, avoiding the complexity of multi-equipment coordination, realizing the full process operation of cyanobacteria emergency treatment, improving the practicability and convenience of the equipment, and has high social use value and application prospects.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0024] Reference Figure 1-16 , an on-water algae-water high-efficiency flotation separation platform, comprising a carrier ship 1, a blue algae extraction pump 3 and a lifting platform 4 are arranged at the bow of the carrier ship 1, an algae mud storage bin 6 and an algae mud delivery pump 601 are arranged at the stern of the carrier ship 1, and an air flotation device body 2 is arranged at the top of the carrier ship 1; The main body 2 of the air flotation device is provided with an air flotation separation tank 201 and a screw press dehydrator 205. The algae slurry with a relatively high concentration separated after treatment in the air flotation separation tank 201 is further dehydrated by the screw press dehydrator 205 to form algae mud. The flotation separation tank 201 is provided with a flocculation stirring box 209, a dissolved air mixing box 211, an algae mud separation box 212 and an algae storage chamber 213. The main body 2 of the flotation device is also provided with a diesel generator 202, an electric control cabinet 203, an air compressor 204, a dissolved air tank 207 and a flocculant mixing box 206. The diesel generator 202 is used to generate electricity for the electrical equipment on board. The flocculant mixing box 206 is provided with a flocculant and a coagulant aid, which are respectively transported to the flocculant through a flocculant delivery pipeline 214 and a coagulant aid delivery pipeline 215. In the flocculation and mixing box 209, a water inlet pipe 216, a tailwater discharge pipe 219 and an algae slurry discharge pipe 220 are respectively installed on the flotation separation tank 201. The water inlet pipe 216 extends into the flocculation and mixing box 209 and is connected to a ring distribution pipe 217. The algae slurry discharge pipe 220 is connected to the algae storage chamber 213 and is connected to the screw dewatering machine 205 through a conveying pipeline. The algae mud dehydrated by the screw dewatering machine 205 is stored in the algae mud storage bin 6, and the algae mud can be pumped out by the algae mud conveying pump 601 and conveyed to the shore tank truck for transportation and treatment.

[0025] During operation, low-concentration algae water is sucked by the blue algae extraction pump 3 and enters the flocculation stirring box 209 through the water inlet pipe 216. After the algae water is mixed with the flocculant and the coagulant aid, the blue algae is stirred to quickly form flocs, and then flows to the dissolved air mixing box 211, and mixes with the dissolved air water and algae water from the dissolved air tank 207, generating a large number of micro-nano bubbles, which adhere to the suspended matter such as the blue algae flocs and float to the water surface, thereby realizing the separation of algae and water.

[0026] The air flotation separation tank 201 is provided with an algae scraping mechanism 7, through which the floating blue algae can be scraped into the algae storage chamber 213 for temporary storage. When the algae storage chamber 213 is full, the algae are transported to the spiral dehydrator 205 for further dehydration treatment. The main body 2 of the air flotation device is detachably mounted on the carrier ship 1, and a hydraulic leg 218 is mounted on the main body 2 of the air flotation device. The main body 2 of the air flotation device is an integrated container, which can be placed on the ship for use, or can be separately hoisted on the shore to treat blue algae, thus realizing the dual-use function of water and land. The hydraulic leg 218 can lift the entire main body 2 of the air flotation device, which is convenient for leveling and transportation on the shore.

[0027] The air compressor 204 generates high-pressure gas and delivers it to the dissolved gas tank 207 , and dissolved gas water is generated in the dissolved gas tank 207 . The dissolved gas water is delivered to the dissolved gas mixing box 211 through the dissolved gas releaser 210 . Example 2

[0028] Reference Figure 1-16The difference between this embodiment and embodiment 1 is that a stirring mechanism 8 is provided in the flocculation stirring box 209, and the stirring mechanism 8 includes a first stirring shaft 801 and a second stirring shaft 802, and the first stirring shaft 801 and the second stirring shaft 802 are synchronously driven by a first synchronous belt 803, and a first bevel gear 804 is fixed to the outside of the second stirring shaft 802, and a first rotating motor 807 is fixed to the outside of the air flotation separation tank 201, and a driving shaft 805 is fixed to the output shaft of the first rotating motor 807, and a second bevel gear 806 is fixed to one end of the driving shaft 805, and the second bevel gear 806 is meshed with the first bevel gear 804; Turning on the first rotating motor 807 can drive the driving shaft 805 and the second bevel gear 806 to rotate, and then drive the second stirring shaft 802 to rotate through the engagement of the second bevel gear 806 with the first bevel gear 804, and then drive the first stirring shaft 801 to rotate through the first synchronous belt 803, thereby stirring the liquid, accelerating mixing, and improving the flocculation effect. Example 3

[0029] Reference Figure 1-16 The difference between this embodiment and embodiment 1 is that a hose 301 is connected to the water inlet end of the blue algae extraction pump 3, a filter mesh 406 is provided on the lifting platform 4, and one end of the hose 301 away from the blue algae extraction pump 3 extends to the bottom of the lifting platform 4 and is connected to the filter mesh 406; The algae water above the lifting platform 4 can be sucked by the blue algae extraction pump 3, and the algae water can be filtered through the filter mesh 406 to filter out large particles of impurities in the water.

[0030] A second rotary motor 407 is fixed to the top of the lifting platform 4 by a bracket, and a first cleaner 408 is fixed to the output shaft of the second rotary motor 407. The first cleaner 408 corresponds to the position of the filter mesh 406, and the first cleaner 408 is in contact with the top of the lifting platform 4. The second rotating motor 407 can drive the first cleaner 408 to rotate relative to the lifting platform 4, so that the impurities blocked at the top of the filter mesh 406 can be scraped off, thereby achieving the purpose of automatically cleaning the impurities and improving the suction efficiency.

[0031] Among them, the two sides of the lifting platform 4 are hinged to the carrier ship 1 through two connecting rods 401 arranged parallel to each other, and a strip sliding opening 402 is opened on the upper connecting rod 401. An electric hoist 403 is fixed directly above the lifting platform 4 through a bracket, and a hook 404 is connected to the output end of the electric hoist 403. A hanging ring 405 is movably installed in the strip sliding opening 402, and the hanging ring 405 is hung on the hook 404. The lifting platform 4 can be lifted by driving the hook 404 to move up and down through the electric hoist 403. Due to the parallelogram connecting rod mechanism between the two sides of the lifting platform 4 and the carrier ship 1, it can ensure that the lifting platform 4 remains in a horizontal state during the lifting process. After a period of suction, the concentration of algae water at a specific depth will drop sharply, resulting in the phenomenon of empty suction. At this time, the height of the lifting platform 4 can be changed to suck algae water at different depths to improve the suction efficiency. Example 4

[0032] Reference Figure 1-16 The difference between this embodiment and embodiment 3 is that both sides of the lifting platform 4 are connected with cyanobacteria enclosures 501, the cyanobacteria enclosures 501 are floating mesh structures, and the cyanobacteria enclosures 501 are moved by the remote control enclosure boat 5. The cyanobacteria are enclosed in a smaller range by the cyanobacteria enclosures 501, so as to achieve the effect of enriching the algae water concentration, and then concentratedly sucked, which can effectively improve the efficiency of sucking cyanobacteria. Example 5

[0033] Reference Figure 1-16 The difference between this embodiment and embodiment 1 is that the algae scraping mechanism 7 includes two driving shafts 701 arranged in parallel with each other, one of which is driven to rotate by a third rotating motor 702, and both ends of the driving shaft 701 are provided with synchronous wheels 703, and a second synchronous belt 704 is installed between the outer sides of the two synchronous wheels 703 on the same side, and a plurality of scrapers 9 are fixed between the two second synchronous belts 704, and the scrapers 9 are equidistantly distributed on the second synchronous belt 704; The third rotating motor 702 can drive the second synchronous belt 704 to move in a circular motion, thereby driving the scraper 9 to follow the circular motion. When the scraper 9 is facing downward, the lower edge of the scraper 9 is immersed in the water, thereby being able to scrape the blue algae floating on the water surface toward the algae storage chamber 213, and continuously scraping the algae. Example 6

[0034] Reference Figure 1-16The difference between this embodiment and embodiment 5 is that the scraper 9 includes a fixed part 901 and a rotating part 902, and an automatic switch is connected to the mounting shaft of the rotating part 902. When the scraper 9 is facing downward, the rotating part 902 switches to a vertical state, and when the scraper 9 is facing upward, the rotating part 902 switches to a horizontal state. Since the scraper 9 has the function of automatic bending, when the scraper 9 is running to the upward state, on the one hand, the height is lower and will not protrude to the outside of the flotation separation tank 201, and the occupied space is lower. On the other hand, the interior of the flotation separation tank 201 is located directly above the scraping algae mechanism 7 and a second cleaner 911 is fixed. When the scraper 9 is facing upward and moving, it can pass under the second cleaner 911, so that the surface of the scraper 9 can be automatically cleaned by the second cleaner 911, and the cyanobacteria remaining on the surface of the scraper 9 can be scraped off to prevent the residual cyanobacteria from being brought back into the water.

[0035] In order to achieve the purpose of automatically switching between two states, the automatic switch includes a sleeve 909 fixed on the mounting shaft of the rotating part 902, a spiral limiting groove 903 is opened on the outer side of the sleeve 909, and a telescopic rotating shaft 904 is elastically and movably installed on the end of the sleeve 909 away from the rotating part 902, and a hemispherical trigger member 905 is fixed on the end of the telescopic rotating shaft 904 away from the sleeve 909, and a limiting guide rod 906 is fixed on the side of the hemispherical trigger member 905 close to the fixed part 901, and a limiting rod 907 is fixed on the side of the limiting guide rod 906 close to the sleeve 909, and one end of the limiting rod 907 extends into the spiral limiting groove 903, and a limiting slide rail 908 is fixed on the fixed part 901, and the limiting slide rail 908 and the limiting guide rod 906 are horizontally matched, and a pushing component 910 is fixed on the inner walls of both sides of the air flotation separation tank 201, and the pushing component 910 is a U-shaped structure.

[0036] When the scraper 9 is running to the upward state, the pushing component 910 and the hemispherical trigger member 905 are offset and do not contact each other. At this time, the spring inside the sleeve 909 pushes the telescopic shaft 904 away. Fig.16 In this state, due to the elastic force of the spring, the rotating part 902 will be kept rotating to a horizontal state. When the scraper 9 runs to a downward state, it is in Fig.15 State, at this time, due to the squeezing of the hemispherical trigger member 905 by the pushing component 910, the telescopic rotating shaft 904 moves toward the sleeve 909, and due to the limiting effect of the limiting slide rail 908, the hemispherical trigger member 905 cannot rotate relative to the fixed part 901, and one end of the limiting rod 907 extends into the spiral limiting groove 903. Therefore, the limiting rod 907 can push the sleeve 909 to rotate relative to the fixed part 901 when moving horizontally, and then drive the rotating part 902 to rotate to a vertical state, so that algae can be scraped off, thereby achieving the purpose of automatic switching state.
