Description

Technical Field

[0001] This utility model relates to the field of air flotation machines, and in particular to a series-type air flotation machine for sewage treatment. Background Technology

[0002] A series-connected dissolved air flotation (DAF) unit is a highly efficient wastewater treatment device. It connects multiple flotation units in series, allowing wastewater to undergo further treatment as it passes through each unit. This equipment typically includes a storage tank, a mixer, and a bubble generator. In the series design, each unit can be optimized for specific pollutants, thereby improving overall treatment efficiency.

[0003] In existing series-type wastewater treatment flotation machines, the fixed scraper structure makes the disassembly and maintenance of the scrapers difficult, requiring a lot of manpower and time. After long-term use, the efficiency of the fixed scrapers will gradually decrease due to wear and corrosion, requiring frequent replacement and increasing maintenance costs. In order to address this technical problem, this application proposes a series-type wastewater treatment flotation machine. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 One embodiment of this utility model is a series-type wastewater treatment flotation machine, comprising:

[0029] The reaction chamber 1 has a motor 2 mounted on its top via a fixed frame. A stirring roller 3 for mixing wastewater is fixedly connected to the drive end of the motor 2, and the outer wall of the stirring roller 3 is connected to another stirring roller 3 via a linkage. A top plate 5 is fixedly connected to the middle of the top of the reaction chamber 1. A water pump 7 is fixedly connected to the inner wall of the top plate 5. A water pump 6 is installed at the top of the water pump 7, and a second water pump 8 is fixedly connected to the top of the water pump 6. A baffle 9 for separating wastewater is fixedly connected to the middle of the inner wall of the reaction chamber 1. A motor 10 is mounted on the top side of the front of the reaction chamber 1 via a fixed frame. A rotating roller 11 is fixedly connected to the drive end of the motor 10, and the rotating roller 11 is connected to another rotating roller 11 via a belt 12. A fixing groove 13 is fixedly connected to the outer periphery of the belt 12, and a clamp is rotatably connected to the left side of the top of the fixing groove 13. Plate 14, a pull rod 15 is slidably connected to the inner wall of the top side of the plate 14, a slide rod 16 is fixedly connected to the right end of the pull rod 15, a clamp head 17 is fixedly connected to the right end of the slide rod 16, the clamp head 17 is set on the inner wall of the top side of the pull rod 15, a spring 18 is set on the outer wall of the slide rod 16, a scraper 19 is set on the inner wall of the fixing groove 13 and the plate 14, a filter box 20 is fixedly connected to the right end of the reaction box 1, a motor 21 is installed at the top of the filter box 20 through a fixing frame, a filter plate 31 is connected to the drive end of the motor 21 through a rotating rod 24 and a brush 25, a pull rod 26 is connected to the front side of the top of the filter box 20 through a fixing sleeve 28 and a slide rod 29, a baffle 27 is fixedly connected to the bottom end of the pull rod 26, and both the pull rod 26 and the baffle 27 are slidably connected to the inner wall of the front side of the filter box 20;

[0030] Specifically, starting motor 2 drives two stirring rollers 3 to rotate via belt 4, stirring the sewage and chemical agents in reaction tank 1 to ensure thorough mixing. Then, water pump 6 is started, pumping water through suction pipes 7 and 8 to the middle of reaction tank 1, allowing the sewage to wait for the chemical agents to take effect. The sewage then passes through baffle 9 to the right side of reaction tank 1. Pulling lever 15 moves slide rod 16, which in turn moves clamp 17. Clamp 17 releases clamp plate 14 from the fixed groove 13, allowing scraper 19 to be disassembled for regular inspection, cleaning, and maintenance. This reduces wear and extends the scraper's lifespan, ensuring long-term stable operation of the equipment. Alternatively, the number of scrapers 19 can be increased based on the amount of floating scum, allowing more floating debris to be scraped away simultaneously, thus improving sewage treatment efficiency.

[0031] Reference Figure 1 , Figure 4 and Figure 5 The rotating rod 24, located at the drive end of motor 21, has a brush 25 rotatably connected to its bottom end. The brush 25 is slidably connected to the inner wall of filter box 20 and is positioned at the top of filter plate 31. A spur gear 22 is located on the top side of the outer wall of rotating rod 24. A rack 23 is meshed with the right end of the spur gear 22 and is fixedly connected to the right side of the inner wall of reaction chamber 1. Under the action of the spur gear 22 and rack 23, motor 21 is slidably connected to the top right side of filter box 20 via a fixing frame. The fixing sleeve 28 is located at the front side of the top of filter box 20. A sliding rod 29 is slidably connected to the inner wall of the fixed sleeve 28. The sliding rod 29 is located on the inner right side of the pull rod 26. A spring 30 is located on the outer wall of the sliding rod 29. One end of the spring 30 is located on the left side of the outer wall of the sliding rod 29, and the other end of the spring 30 is located on the inner wall of the fixed sleeve 28. One end of the spring 18 is located on the inner wall of the pull rod 15, and the other end of the spring 18 is located on the left end of the clamp 17. The outer wall of the stirring roller 3 is connected to another stirring roller 3 through the belt 4. A water inlet pipe is located on the left front end of the reaction tank 1, and water outlet pipes are located on the right front end of the reaction tank 1 and the front end of the filter box 20.

[0032] Specifically, pull the slide bar 29 to release the engagement of the pull rod 26. Then, pull the pull rod 26 to move the baffle 27 upward. Under the action of the spring 30, the slide bar 29 is sprung into the slot below the pull rod 26, thus fixing the pull rod 26. Then, start the motor 3 21 to drive the spur gear 22 to rotate. Under the action of the rack 23, the spur gear 22 drives the brush 25 to move on the filter plate 31 through the rotating rod 24, thereby scraping off the filtered floating impurities on the filter plate 31, preventing the filter plate 31 from clogging, ensuring the unobstructed flow of sewage treatment, and thus improving treatment efficiency. Sewage enters the reaction tank 1 through the inlet pipe. After purification, the water flows to the appropriate position through the outlet on the right side of the reaction tank 1. The water in the filter tank 20 flows out through the outlet at its front end.

[0033] Working principle: Wastewater is injected into reaction tank 1 through the inlet pipe, followed by the addition of chemical reagents. Motor 2 is started, driving two stirring rollers 3 via belt 4 to rotate, stirring the wastewater and chemical reagents in reaction tank 1 to ensure thorough mixing. Then, water pump 6 is started, pumping water through suction pipes 7 and 8 to the middle of reaction tank 1, allowing the wastewater to remain in the middle while the chemical reagents take effect. Afterward, the wastewater passes through baffle 9 to the right side of reaction tank 1. Motor 10 is then started, driving the reaction tank through belt 12... The rotating roller 11 rotates, thereby driving the scraper 19 on the roller 11 to move and scrape off the scum on top of the sewage. The number of scrapers 19 can be increased according to the floating scum passing through the fixing groove 13 and the clamping plate 14 on the roller 11, so that more floating objects can be scraped off at the same time. The scraped scum will then enter the filter box 20 and be filtered by the filter plate 31. After the filter plate 31 has been used for a period of time, the sliding rod 29 is pulled to release the engagement of the pull rod 26. Then, the pull rod 26 is pulled to drive the baffle 2. 7. Moving upwards, under the action of spring 20, slide rod 29 is sprung into the slot below pull rod 26, thus fixing pull rod 26. Then, motor 321 is started to drive the spur gear 22 to rotate. Under the action of rack 23, the spur gear 22 drives brush 25 to move on filter plate 31 through rotating rod 24, thereby scraping off the filtered floating impurities on filter plate 31, preventing filter plate 31 from clogging, and ensuring the smooth flow of sewage treatment. The purified water flows out through the outlet on the right side of reaction tank 1. When the filter box 20 reaches the appropriate position, the water flows out through the outlet at its front end. Then, by pulling the pull rod 15, the slide rod 16 is moved, causing the slide rod 16 to move the clamp 17. Under the action of the clamp 17, the clamp plate 14 is released from the fixing groove 13, and the clamp plate 14 is opened from the fixing groove 13. The scraper 19 can be disassembled and installed, which facilitates regular inspection, cleaning and maintenance of the scraper 19, reduces wear on the scraper 19, and extends the service life of the scraper 19, ensuring long-term stable operation of the equipment.
