Description

Technical Field

[0001] This utility model relates to the field of algae-water air flotation separation technology, and in particular to an algae-water air flotation separation device for air-flotation algae boats. Background Technology

[0002] In traditional cyanobacteria flotation separation equipment, the scraper design has significant shortcomings. Typically, the scraper structure is relatively simple and fixed, which exposes many problems during the algae scraping process.

[0003] On the one hand, the scraper cannot be flexibly adjusted according to its own position during operation. When the scraper moves upward, due to its fixed shape, it protrudes into the internal space of the air flotation separator. This not only occupies a large space, but also easily causes blockage and collision risks inside the equipment, reducing the stability and reliability of the equipment operation.

[0004] On the other hand, traditional scrapers lack effective self-cleaning functions. After scraping off the blue-green algae, a large amount of algae remains on the scraper surface. As the scraper moves in a cycle, this residual algae easily falls back into the water, causing secondary pollution. This makes the scraping work less effective and seriously affects the efficiency and effectiveness of blue-green algae treatment, failing to meet the need for efficient and thorough control of blue-green algae.

[0005] In order to solve the problems mentioned in the background art, the present invention provides an algae-water air flotation separation device for air-flotation algae boats.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An algae-water air flotation separation device for an air-flotation algae boat includes a carrier vessel, the top of which is equipped with the main body of the air flotation device.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Example 1

[0040] Reference Figure 1-16 An algae-water air flotation separation device for an air-floating algae boat includes a carrier boat 1. The bow of the carrier boat 1 is equipped with a blue algae extraction pump 3 and a lifting platform 4. The stern of the carrier boat 1 is equipped with an algae sludge storage bin 6 and an algae sludge conveying pump 601. The top of the carrier boat 1 is equipped with an air flotation device body 2.

[0041] The main body 2 of the air flotation device is equipped with an air flotation separation tank 201 and a screw press dewatering machine 205. The high-concentration algae water separated after treatment in the air flotation separation tank 201 is further dewatered by the screw press dewatering machine 205 to form algae sludge.

[0042] The air flotation separation tank 201 is equipped with a flocculation mixing tank 209, a dissolved air mixing tank 211, an algae-sludge separation tank 212, and an algae storage chamber 213. The main body 2 of the air flotation device is also equipped with a diesel generator 202, an electrical control cabinet 203, an air compressor 204, a dissolved air tank 207, and a flocculant mixing tank 206. The diesel generator 202 is used to generate electricity to power the ship's electrical equipment. The flocculant mixing tank 206 contains flocculant and coagulant aid, which are transported to the flocculant via flocculant delivery pipe 214 and coagulant aid delivery pipe 215, respectively. Inside the flocculation mixing tank 209, an inlet pipe 216, a tailwater discharge pipe 219, and an algae slurry discharge pipe 220 are installed on the air flotation separation tank 201. The inlet pipe 216 extends into the flocculation mixing tank 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 press dewatering machine 205 through a conveying pipe. The algae sludge after dewatering by the screw press dewatering machine 205 is stored in the algae sludge storage bin 6. The algae sludge can be extracted by the algae sludge conveying pump 601 and transported to the shore tanker for transportation and processing.

[0043] During operation, low-concentration algae water is drawn in by the cyanobacteria extraction pump 3 and enters the flocculation mixing tank 209 through the water inlet pipe 216. After the algae water is mixed with flocculant and coagulant aid, it is stirred to make the cyanobacteria quickly form flocs. Then it flows to the dissolved air mixing tank 211 and mixes with the dissolved air water from the dissolved air tank 207 to generate a large number of micro-nano-sized bubbles. These bubbles adhere to the suspended matter such as cyanobacteria flocs and float to the water surface, thereby achieving algae and water separation.

[0044] An algae scraping mechanism 7 is installed on the air flotation separation tank 201. The floating blue algae can be scraped into the algae storage chamber 213 for temporary storage. When the algae storage chamber 213 is full, it is transported to the screw press dewatering machine 205 for further dewatering.

[0045] The main body 2 of the air flotation device can be detachably installed on the carrier ship 1, and hydraulic legs 218 are installed on the main body 2 of the air flotation device. The main body 2 of the air flotation device is an integral container, which can be used not only on the ship, but also separately hoisted on the shore to treat blue-green algae. The hydraulic legs 218 can lift the entire main body 2 of the air flotation device, making it convenient to level and transfer on the shore.

[0046] The air compressor 204 generates high-pressure gas and delivers it to the dissolved gas tank 207, where dissolved gas water is generated. The dissolved gas water is then delivered to the dissolved gas mixing box 211 via the dissolved gas release device 210.

[0047] Example 2

[0048] Reference Figure 1-16 The difference between this embodiment and embodiment 1 is that the flocculation mixing tank 209 is provided with a stirring mechanism 8, which includes a first stirring shaft 801 and a second stirring shaft 802. The first stirring shaft 801 and the second stirring shaft 802 are synchronously driven by a first synchronous belt 803. A first bevel gear 804 is fixed to the outside of the second stirring shaft 802. A first rotary motor 807 is fixed to the outside of the air flotation separation tank 201. A drive shaft 805 is fixed to the output shaft of the first rotary motor 807. A second bevel gear 806 is fixed to one end of the drive shaft 805. The second bevel gear 806 meshes with the first bevel gear 804.

[0049] Turning on the first rotary motor 807 can drive the drive shaft 805 and the second bevel gear 806 to rotate. Then, the second bevel gear 806 meshes with the first bevel gear 804 to drive the second stirring shaft 802 to rotate. Then, the first synchronous belt 803 drives the first stirring shaft 801 to rotate as well, thereby stirring the liquid, accelerating the mixing, and improving the flocculation effect.

[0050] Example 3

[0051] Reference Figure 1-16 The difference between this embodiment and embodiment 1 is that the inlet end of the blue algae extraction pump 3 is connected to a hose 301, and a filter screen 406 is provided on the lifting platform 4. The end of the hose 301 away from the blue algae extraction pump 3 extends to the bottom of the lifting platform 4 and communicates with the filter screen 406.

[0052] The algae extraction pump 3 can draw algae water from above the lifting platform 4. The algae water can be filtered through the filter mesh 406 to remove large particles of impurities.

[0053] The second rotary motor 407 is fixed above the lifting platform 4 by a bracket. The output shaft of the second rotary motor 407 is fixed with the first cleaner 408. The first cleaner 408 corresponds to the position of the filter screen 406 and is in contact with the top of the lifting platform 4.

[0054] The second rotary motor 407 can drive the first cleaner 408 to rotate and move relative to the lifting platform 4, thereby scraping away the impurities clogging the top of the filter mesh 406, achieving the purpose of automatically cleaning impurities and improving suction efficiency.

[0055] The lifting platform 4 is hinged to the carrier ship 1 on both sides by two parallel connecting rods 401. A strip-shaped sliding opening 402 is provided on the upper connecting rod 401. An electric hoist 403 is fixed to the top of the lifting platform 4 by a bracket. The output end of the electric hoist 403 is connected to a hook 404. A hanging ring 405 is movably installed in the strip-shaped sliding opening 402. The hanging ring 405 is hung on the hook 404. The lifting platform 4 can be lifted by moving the hook 404 up and down through the electric hoist 403. Due to the parallelogram linkage mechanism between the two sides of the lifting platform 4 and the carrier ship 1, the lifting platform 4 can be kept horizontal during the lifting process. Since the concentration of algae water at a certain depth will drop sharply after a period of suction, causing the phenomenon of empty suction, the height of the lifting platform 4 can be changed to suction algae water at different depths to improve the suction efficiency.

[0056] Example 4

[0057] Reference Figure 1-16 The difference between this embodiment and embodiment 3 is that both sides of the lifting platform 4 are connected to cyanobacteria enclosures 501. The cyanobacteria enclosures 501 are floating mesh structures, and the cyanobacteria enclosures 501 are moved by the remote-controlled gathering boat 5. The cyanobacteria are gathered in a small area by the cyanobacteria enclosures 501 to achieve the effect of enriching the algae water concentration, and then concentrated for suction, which can effectively improve the efficiency of cyanobacteria suction.

[0058] Example 5

[0059] Reference Figure 1-16 The difference between this embodiment and embodiment 1 is that the algae scraping mechanism 7 includes two parallel drive shafts 701. One drive shaft 701 is driven to rotate by a third rotary motor 702. Both ends of the drive shaft 701 are provided with synchronous pulleys 703. A second synchronous belt 704 is installed between the outer sides of the two synchronous pulleys 703 on the same side. A plurality of scrapers 9 are fixed between the two second synchronous belts 704. The scrapers 9 are evenly distributed on the second synchronous belts 704.

[0060] The third rotary motor 702 can drive the second synchronous belt 704 to move cyclically, thereby driving the scraper 9 to move cyclically. When the scraper 9 is facing down, the lower edge of the scraper 9 is submerged in the water, thereby scraping the blue algae floating on the water surface towards the algae storage chamber 213, and can continuously scrape algae.

[0061] Example 6

[0062] 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. An automatic switcher is connected to the mounting shaft of the rotating part 902. When the scraper 9 is facing down, the rotating part 902 switches to a vertical state. When the scraper 9 is facing up, the rotating part 902 switches to a horizontal state. Since the scraper 9 has an automatic bending function, when the scraper 9 is in the upward state, on the one hand, the height is lower and it will not protrude to the outside of the air flotation separation tank 201, thus occupying less space. On the other hand, the second cleaner 911 is fixed inside the air flotation separation tank 201 directly above the algae scraping mechanism 7. When the scraper 9 is facing up and moving, it can pass under the second cleaner 911, so that the second cleaner 911 can automatically clean the surface of the scraper 9, scraping off the residual blue algae on the surface of the scraper 9 and preventing the residual blue algae from being carried back into the water.

[0063] To achieve automatic switching between two states, the automatic switcher includes a sleeve 909 fixed on the mounting shaft of the rotating part 902. A helical limiting groove 903 is provided on the outer side of the sleeve 909. A telescopic rotating shaft 904 is elastically mounted on the end of the sleeve 909 away from the rotating part 902. A hemispherical trigger 905 is fixed on the end of the telescopic rotating shaft 904 away from the sleeve 909. A limiting guide rod 906 is fixed on the side of the hemispherical trigger 905 near the fixed part 901. A limiting rod 907 is fixed on the side of the limiting guide rod 906 near the sleeve 909. One end of the limiting rod 907 extends into the helical limiting groove 903. A limiting slide rail 908 is fixed on the fixed part 901. The limiting slide rail 908 and the limiting guide rod 906 are horizontally matched. Pushing components 910 are fixed on the inner walls of both sides of the air flotation separation tank 201. The pushing components 910 have a U-shaped structure.

[0064] When the scraper 9 rotates to the upward position, the pushing component 910 and the hemispherical trigger 905 are misaligned and will not contact each other. At this time, due to the action of the spring inside the sleeve 909, the telescopic shaft 904 will be pushed away. Figure 16 In this state, due to the spring force, the rotating part 902 will remain rotated to a horizontal state. When the scraper 9 rotates to the downward state, it is in a state of... Figure 15 In this state, due to the compression of the hemispherical trigger 905 by the pushing component 910, the telescopic rotating shaft 904 moves toward the sleeve 909. Due to the limiting effect of the limiting slide rail 908, the hemispherical trigger 905 cannot rotate relative to the fixed part 901. One end of the limiting rod 907 extends into the spiral limiting groove 903. Therefore, when the limiting rod 907 moves horizontally, it can push the sleeve 909 to rotate relative to the fixed part 901, thereby driving the rotating part 902 to rotate to the vertical state, so as to scrape algae and achieve the purpose of automatic state switching.
