Description

Technical Field

[0001] This utility model relates to the field of bubble generator technology, and more specifically, to a micro-nano bubble generator. Background Technology

[0002] In fields requiring air flotation processes, such as wastewater treatment and industrial flotation, micro-nano bubble generators play a crucial role. They are often used in conjunction with external air flotation tanks, using pipeline connections to achieve the mixing and separation of bubbles with wastewater or suspended particles. However, in practical applications, this connection method has significant drawbacks. Industrial environments are complex, and pipelines are susceptible to various external forces. During equipment installation and maintenance, operator error may pull on the pipelines. Material handling equipment moving in the factory may also collide with the pipelines. If there is vibrating equipment, long-term vibration can cause the pipeline to shift position and bear additional tensile forces. Strong tension on the pipeline can easily cause the connection between the pipeline and the bubble generator or air flotation tank to loosen. After loosening, micro-nano bubbles leak from the loose point, drastically reducing the amount of bubbles entering the air flotation tank, seriously affecting the air flotation effect. For example, in wastewater treatment, suspended solids in wastewater are difficult to separate, resulting in substandard effluent quality. In industrial flotation, flotation efficiency is reduced, and product quality is affected. To solve this problem, some existing technologies use threaded or flanged connections to enhance robustness. However, while these two connection methods are robust, the installation and disassembly processes are complex, increasing the difficulty and cost of equipment maintenance. Improvements are urgently needed to meet actual usage requirements. Utility Model Content

[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a micro / nano bubble generator, comprising:

[0024] The generator body 1 has an inlet pipe 14 fixedly sleeved on the left side and an outlet pipe 2 fixedly sleeved on the right side.

[0025] The connecting mechanism is designed on the outer surface of the liquid outlet pipe 2;

[0026] The connecting mechanism includes a fixed pipe 3, the inside of which is fixedly sleeved with the outer surface of the outlet pipe 2. A first connector 4 is fixedly installed at the right end of the fixed pipe 3. A second connector 5 is movably sleeved inside the first connector 4. An air flotation tank connecting pipe 6 is fixedly sleeved inside the second connector 5. A fixed block 7 is fixedly installed on the outer surface of the second connector 5. A rotating rod 8 is movably connected inside the fixed block 7. A first hinge block 9 is hinged inside the left end of the rotating rod 8. A moving ring 10 is fixedly installed on the outer surface of the first hinge block 9. A threaded sleeve 11 is movably sleeved inside the moving ring 10. A threaded part 12 is threaded inside the threaded sleeve 11. The inside of the threaded part 12 is fixedly connected to the outer surface of the fixed pipe 3.

[0027] When the second connector 5 is fitted inside the first connector 4, the liquid outlet pipe 2 and the interior of the flotation tank connecting pipe 6 will be connected through the fixed pipe 3, the first connector 4 and the second connector 5. At this time, the operator will turn the rotating rod 8 to rotate around the first hinge block 9. When the outer surfaces of the four rotating rods 8 are respectively hooked into the interior of the four fixed blocks 7, the operator will turn the threaded sleeve 11. Since the threaded sleeve 11 is threadedly fitted with the outer surface of the threaded part 12, the threaded sleeve 11 will move to the left while rotating. At the same time, the threaded sleeve 11 will drive the four rotating rods 8 to move to the left through the moving ring 10 and the four first hinge blocks 9. When the right side of the rotating rod 8 contacts the fixed block 7, the rotating rod 8 will pull the fixed block 7. At this time, the rotating rod 8 will cooperate with the fixed block 7 to connect the first connector 4 as a whole with the second connector 5 as a whole, thereby making the generator body 1 and the flotation tank firmly connected.

[0028] The first connector 4 has a gasket 13 fixedly fitted inside, and the right side of the gasket 13 abuts against the left side of the second connector 5.

[0029] Due to the design of the gasket 13, the sealing between the first connector 4 and the second connector 5 will be enhanced.

[0030] The generator body 1 has an air inlet pipe 15 fixedly sleeved inside the top left side, and a filter screen 26 is movably sleeved on the left side of the outer surface of the air inlet pipe 15.

[0031] Due to the design of the filter 26, it can effectively filter the air drawn in by the intake pipe 15.

[0032] Among them, a circular plate 16 is fixedly installed on the right side of the filter screen 26. The inside of the circular plate 16 is movably connected to the outer surface of the air intake pipe 15. A moving block 17 is slidably connected inside the circular plate 16. A spring 18 is fixedly installed on the outer surface of the moving block 17. The other end of the spring 18 is fixedly connected to the inside of the circular plate 16. A locking block 19 is fixedly installed on the right side of the moving block 17. A fixing ring 20 is movably connected to the outer surface of the locking block 19. The inside of the fixing ring 20 is fixedly connected to the outer surface of the air intake pipe 15.

[0033] When the filter screen 26 drives the circular plate 16 to move to the right along the outer surface of the air intake pipe 15, the outer surface of the locking block 19 will contact and be squeezed by the fixing ring 20 during the rightward movement. This causes the locking block 19 to drive the moving block 17 to move in opposite directions along the inside of the circular plate 16. At this time, the spring 18 will be compressed by the moving block 17. When the right side of the circular plate 16 is in contact with the left side of the fixing ring 20, the locking block 19 will move to the locking groove of the fixing ring 20. Due to the elastic force of the spring 18, the locking block 19 will be locked into the locking groove of the fixing ring 20 under the action of the spring 18, thereby completing the connection between the filter screen 26 and the air intake pipe 15.

[0034] The outer surface of the circular plate 16 is provided with a groove 21, and a slider 22 is slidably connected inside the groove 21. A second hinge block 23 is fixedly installed on the outer surface of the slider 22.

[0035] Due to the design of the slide groove 21, the movement of the slider 22 is limited, so that the slider 22 can only move left and right along the inside of the slide groove 21. When the operator presses the two slide grooves 21 at the same time, the two slide grooves 21 will drive the two sets of second hinge blocks 23 to move towards each other.

[0036] The second hinge block 23 has a movable rod 24 hinged inside, and the other end of the movable rod 24 is hinged to a third hinge block 25. The outer surface of the third hinge block 25 is fixedly connected to the outer surface of the moving block 17.

[0037] When the two sets of second hinge blocks 23 move toward each other, they will squeeze and push the two sets of third hinge blocks 25 through the two sets of movable rods 24, so that the two sets of third hinge blocks 25 drive the two moving blocks 17 to move in opposite directions. Then, the two locking blocks 19 will be disengaged from the locking groove of the fixing ring 20 by the two moving blocks 17. At this time, the operator will be able to remove the filter screen 26 from the air intake pipe 15.

[0038] Working principle and usage process of this utility model:

[0039] When the operator needs to connect the generator body 1 to the flotation tank connecting pipe 6 on the flotation tank, the operator first sleeves the second connecting piece 5 inside the first connecting piece 4. Then, the operator successively twists the four rotating rods 8, causing them to rotate around the four first hinge blocks 9. When the outer surfaces of the four rotating rods 8 contact the inside of the four fixed blocks 7 during rotation, the operator twists the threaded sleeve 11. Because the inside of the threaded sleeve 11 is threaded onto the outer surface of the threaded portion 12, when the threaded sleeve 11 rotates along the outer surface of the threaded portion 12, it will simultaneously move to the left. Due to the movement of the ring 1... The inner surface of the 0 is movably connected to the outer surface of the threaded sleeve 11. At this time, the moving ring 10 will move to the left under the drive of the threaded sleeve 11. The moving ring 10 will pull the four rotating rods 8 through the four first hinge blocks 9, so that the four rotating rods 8 will move to the left. Then, the right side of the outer surface of the four rotating rods 8 will contact the four fixed blocks 7 during the leftward movement. At this time, the four rotating rods 8 will pull the four fixed blocks 7. At this time, the four rotating rods 8 will cooperate with the four fixed blocks 7 to connect the first connecting piece 4 as a whole with the second connecting piece 5 as a whole, thereby realizing the function of enabling the generator body 1 to be easily and firmly connected to the flotation tank.

[0040] When the operator needs to prevent dust from being drawn into the generator body 1 during the intake process, the operator will attach the filter screen 26 to the outer surface of the intake pipe 15. Due to the design of the filter screen 26, it can effectively filter dust in the air. At the same time, the circular plate 16 will move to the right along the outer surface of the intake pipe 15 under the action of the filter screen 26. When the two locking blocks 19 come into contact with the fixing ring 20 during the rightward movement, they will be squeezed by the outer surface of the fixing ring 20. At this time, the two locking blocks 19 will drive the two moving blocks 17 to move. Due to the internal limit of the circular plate 16, the two moving blocks 17 will move in opposite directions along the inside of the circular plate 16 under the action of the two locking blocks 19. During this process, the two springs 18 will be compressed by the two moving blocks 17. When the right side of the circular plate 16 is in contact with the left side of the fixing ring 20, the locking blocks 19 will move to the locking slot on the fixing ring 20. Due to the elastic force of the springs 18, When the filter screen 26 is assembled with the intake pipe 15, the two locking blocks 19 will move towards each other and insert into the slots of the fixing ring 20. When the operator needs to disassemble and replace the filter screen 26, the operator will press the two sliders 22 at the same time, so that the two sliders 22 move towards each other along the inside of the two slide grooves 21. At this time, the two sliders 22 will drive the two sets of movable rods 24 to move through the two sets of second hinge blocks 23. Then, the two sets of movable rods 24 will squeeze and push the two sets of third hinge blocks 25, so that the two sets of movable rods 24 drive the two moving blocks 17 to move in opposite directions. Then, the two locking blocks 19 will disengage from the slots of the fixing ring 20 during the opposite movement. At this time, the operator can push the filter screen 26 to the left, so that the filter screen 26 is separated from the intake pipe 15, thus realizing the function of conveniently disassembling and assembling the filter screen 26.
