Description

Technical Field

[0001] This utility model relates to the field of microbubble flotation technology, and in particular to a high-efficiency oil removal microbubble flotation machine. Background Technology

[0002] Microbubble flotation is a wastewater treatment device specifically designed to separate suspended solids, grease, or fine particles from liquids. It is commonly used in industrial oily wastewater treatment. In operation, the oil and water to be separated are first poured into the flotation tank. Then, a large number of extremely fine bubbles are injected into the water through the aeration pipe. These microbubbles adhere to the oil droplets or suspended particles in the wastewater, reducing the density of the pollutants and causing them to float to the surface. Finally, the separated grease is scraped off by a scraper, thus achieving solid-liquid or oil-water separation.

[0003] Although existing microbubble flotation machines can perform oil-water separation, the scrapers are in constant contact with oil residue and particulate matter, making them prone to wear and tear. When replacing the scrapers, operators need to manually tighten or loosen the bolts, which is too cumbersome, time-consuming, and labor-intensive, thus reducing the efficiency of the equipment.

[0035] 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.

[0036] Reference Figures 1-4 This utility model provides an embodiment of a high-efficiency oil removal microbubble flotation machine, comprising: a support frame 1; a flotation tank 2, fixedly connected to the top of the flotation tank 2; a partition 8, fixedly connected to the left side of the interior of the flotation tank 2, with holes on both sides of the bottom of the partition 8; a motor 10, located on the rear side of the exterior of the flotation tank 2; a transmission belt 11, installed at the output end of the motor 10; mounting blocks 12 and scrapers 13, the mounting blocks 12 fixedly connected to the outer sides of the transmission belt 11, and the scrapers 13 inserted into the interior of multiple mounting blocks 12; sliders 14 and protrusions 15, the sliders 14 slidably connected to the interior of multiple mounting blocks 12, and the protrusions 15 fixedly connected to the top of multiple sliders 14; a spring 16 and an insert block 17. Spring 16 is fixedly connected to the bottom of multiple sliders 14, and insert block 17 is fixedly connected to the top of multiple sliders 14; and a mixing component is provided, which is used to fully mix liquid and additives. The top of mounting block 12 has a through hole 19, and protrusion 15 is slidably connected inside the through hole 19. The through hole 19 facilitates the movement of protrusion 15. The inside of scraper 13 has a slot 18, and insert block 17 is inserted into the slot 18, which improves the stability of scraper 13 installation. An installation ring 9 is fixedly connected to the rear side of the outside of flotation tank 2, and motor 10 is fixedly connected inside the installation ring 9. The installation ring 9 facilitates the fixation of motor 10. A guide plate 31 is fixedly connected to the right side inside the flotation tank 2. The guide plate 31 facilitates the guidance of the oil flow.

[0037] Specifically, when the scraper 13 for removing grease needs to be replaced, firstly, by moving the protrusion 15, the slider 14 moves synchronously as the protrusion 15 moves. Simultaneously, the insert 17 fixed to its top also moves. At the same time, since the bottom of the slider 14 is connected to a spring 16, an external force is applied to the spring 16 during its movement, causing the spring 16 to compress, produce elastic deformation, and store elastic energy. Then, as the insert 17 continues to move, it gradually disengages from the slot 18 inside the scraper 13. The scraper 13 can be easily removed from the mounting block 12, enabling quick disassembly. When installing a new scraper 13, simply insert it into the mounting block 12. After insertion, release the protrusion 15. Under the reaction force of the spring 16, the slider 14 automatically resets and drives the insert block 17 to re-insert into the corresponding slot 18 inside the new scraper 13, thus completing the installation. This replacement process does not require any bolts or tedious tightening or loosening operations, eliminating the common disassembly and assembly steps in traditional replacement methods. This simplifies the scraper 13 replacement process, thereby improving the equipment's working efficiency and operational stability.

[0038] Reference Figures 2-5 The mixing component includes a second motor 21, which is located on the bottom left side of the flotation tank 2. Rotating rods 25 are rotatably connected to both sides inside the flotation tank 2. The output end of the second motor 21 is fixedly connected to the bottom of the front rotating rod 25. A drive wheel 22 is fixedly connected to the bottom of the front rotating rod 25, and a driven wheel 24 is fixedly connected to the bottom of the rear rotating rod 25. The drive wheel 22 is connected to the driven wheel 24 via a belt 23. Rotating rings 26 are fixedly connected to the outside of both rotating rods 25. Agitator blades 27 are fixedly connected to the outside of the multiple rotating rings 26. The agitator blades 27 facilitate the mixing of oil-water mixture and flocculant. A fixing ring 20 is fixedly connected to the bottom left side of the flotation tank 2, and the second motor 21 is fixedly connected inside the fixing ring 20. The fixing ring 20 facilitates the fixation of the second motor 21.

[0039] Specifically, before using the microbubble flotation machine to separate the oil-water mixture, the oil-water mixture to be treated must first be introduced into the flotation tank 2 through the inlet pipe 3. During this process, the oil-water mixture flows into the flotation tank 2 through the inlet. Subsequently, flocculant is evenly added to the flotation tank 2 on the outer left side of the baffle 8 to ensure that the flocculant is initially dispersed in the water. At this time, motor 21 is started. After motor 21 starts, the drive wheel 22 installed at its output end begins to rotate. At the same time as the drive wheel 22 rotates, the driven wheel 24 also rotates synchronously through the traction of the belt 23. The rotation of the rotating ring causes the two rotating rods 25 installed inside to start rotating. The rotation of the rotating rods 25 further drives the rotating rings 26 fixed on both sides of the outside to rotate in a circular motion. Each rotating ring 26 has multiple stirring blades 27 fixed on its outside. When the rotating ring 26 rotates, the flocculant added to the water can be fully mixed with the oil-water mixture through the continuous rotation of the stirring blades 27. This allows the flocculant to diffuse rapidly and react with the tiny oil droplets or solid suspended particles in the water to form larger flocculent particles, which facilitates the subsequent microbubble flotation process and improves the working efficiency of the microbubble flotation machine.

[0040] Reference Figures 3-7 An aerator 4 is installed at the bottom of the flotation tank 2. A connecting pipe 5 is fixedly connected to the output end of the aerator 4. An aeration pipe 6 is fixedly connected to the top of the connecting pipe 5 through the interior of the flotation tank 2. Aeration ports 7 are installed on both sides of the top of the aeration pipe 6 to facilitate the discharge of air bubbles. A collection box 28 is set on the right side of the exterior of the flotation tank 2 to facilitate the collection of removed grease. A locking block 29 is fixedly connected to both sides of the exterior of the collection box 28. The locking block 29 is set inside the flotation tank 2. An installation groove 30 is opened on the right side of the exterior of the flotation tank 2. The locking block 29 is inserted into the installation groove 30 to facilitate the fixation of the collection box 28. A water inlet pipe 3 is fixedly connected to the left side of the exterior of the flotation tank 2 to facilitate the transportation of the oil-water mixture to be treated into the interior of the flotation tank 2.

[0041] Specifically, when using this microbubble flotation machine, firstly, the oil-water mixture is transported to the interior of the flotation tank 2 through the inlet pipe 3. Then, flocculant is added to the interior of the flotation tank 2. Next, the mixture is stirred to fully mix the flocculant and the oil-water mixture. The mixed oil-water mixture enters the middle of the flotation tank 2. At this time, the aerator 4 is started. With the cooperation of the connecting pipe 5 and the aeration pipe 6, the generated microbubbles are discharged through the aeration port 7. The microbubbles are evenly distributed in the water and rise with the water flow. During the rising process, these microbubbles continuously contact and adhere to the flocs formed by the flocculant, which enhances the overall buoyancy and gradually floats to the surface of the water, thereby achieving the separation of oil and water from impurities. At the same time, the motor 10 is started, which drives the transmission belt 11 installed at the output end to rotate. The rotation of the transmission belt 11 drives the mounting blocks 12 fixed on both sides to rotate. The rotation of the mounting blocks 12 drives the internally inserted scraper 13 to rotate. The rotation of the scraper 13 collects the separated oil and transports it to the interior of the collection box 28 through the guide plate 31.

[0042] Working principle: When the scraper 13 for removing grease needs to be replaced, firstly, the moving protrusion 15 moves laterally with the bottom-fixed slider 14. As the slider 14 moves, it also moves the top-fixed insert block 17. At the same time, the slider 14 compresses the bottom-fixed spring 16, causing the spring 16 to deform under force. Then, when the insert block 17 disengages from the slot 18 inside the scraper 13, the scraper 13 can be separated from the mounting block 12. During installation, the new scraper 13 is inserted into the mounting block 12. Then, the protrusion 15 is released, and under the reaction force of the spring 16, the insert block 17 is inserted into the slot 18 inside the scraper 13. This makes it easy to replace the scraper 13 for removing grease without tightening or loosening bolts. The replacement method is simple and convenient, thereby improving the working efficiency of the equipment.

[0043] Before removing the oil-water mixture, the mixture is first transported to the interior of the flotation tank 2 through the inlet pipe 3. Then, flocculant is added to the outer left side of the baffle 8. At this time, motor 21 is started. Motor 21 drives the drive wheel 22 fixed at the output end to rotate. The rotation of the drive wheel 22 drives the driven wheel 24 to rotate through the belt 23. At the same time, the rotation of the drive wheel 22 and the driven wheel 24 drives the two rotating rods 25 fixed inside to rotate. The rotation of the two rotating rods 25 drives the rotating rings 26 fixed on both sides outside to rotate. The rotation of the rotating rings 26 drives the stirring blades 27 fixed around the outside to rotate. The rotation of the stirring blades 27 can fully mix the flocculant and the oil-water mixture. When using this device, it is easy to fully mix the flocculant and the oil-water mixture. The flocculant can aggregate small oil droplets or solid particles into larger clumps (flocs), thereby improving the working efficiency of the microbubble flotation machine.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
