Description

Technical Field

[0002] Micro-nano bubbles have the characteristics of small bubble size, large specific surface area, high adsorption efficiency, slow rising speed in water, etc.

[0003] When the existing micro-nano bubble generator is used under the condition of alkaline water quality in the north, a large amount of scale is easily generated inside it. Even though its rotary cutting blades are rotating, eddy currents are likely to form in areas such as the back and root of the rotary cutting blades, resulting in a decrease in flow velocity, and scale will also crystallize. As the scale increases, it will affect the dynamic balance of the rotary cutting blades, leading to an increase in noise and energy consumption. It will also cause insufficient shear force on the surface of the rotary cutting blades, affecting the effect of micro-nano bubble generation; the existing generator is difficult to clean the scale inside, it is difficult to carry out high-frequency cleaning, and it is not convenient to set up a descaling structure, and it is easy to affect the use effect of the rotary cutting blades due to the setting of the descaling structure.

[0054] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0055] Embodiment: Please refer to Figure 1 - Figure 11 , a micro-nano bubble bath generator, comprising a tank body 1, an air injection pipe 2 and a water injection pipe 3, and further comprising:

[0056] A premixing mechanism, which includes a premixing cylinder 4 installed inside the tank body 1 and a mixing pipe 5 installed inside the premixing cylinder 4. The air injection pipe 2 and the water injection pipe 3 are both connected to the mixing pipe 5. A fixed plate 17 is installed inside the tank body 1. One side of the bottom of the premixing cylinder 4 is provided with a first diversion pipe 18, and a first solenoid valve 19 is installed on the first diversion pipe 18. The first diversion pipe 18 penetrates through the fixed plate 17.

[0057] Air and tap water are injected into the mixing pipe 5 through the air injection pipe 2 and the water injection pipe 3, so that the tap water and air are initially mixed inside the premixing cylinder 4.

[0058] The generating mechanism includes two generating tanks 6 arranged inside the tank body 1, a tube shaft 7 installed inside the generating tank 6, and a fixed cylinder 8 fixedly sleeved outside the tube shaft 7. A plurality of rotary cutting blades 9 are installed on the fixed cylinder 8. On one side of the top of the generating tank 6, a second diversion tube 20 is installed. The second diversion tube 20 cooperates with the first diversion tube 18. An electromagnet coil is installed at the bottom end of the first diversion tube 18, and a sealing iron ring is slidably installed at the top end of the second diversion tube 20. When the second diversion tube 20 rotates to the bottom of the first diversion tube 18, the sealing iron ring is adsorbed by energizing the electromagnet coil, so that the first diversion tube 18 and the second diversion tube 20 are hermetically docked. At the bottom of the two generating tanks 6, a third diversion tube 21 is installed. The third diversion tube 21 is of a Y-shaped structure, and two second solenoid valves 22 are installed on the third diversion tube 21. At the bottom of one side of the tank body 1, a discharge pipe 23 is installed. The top end of the discharge pipe 23 is rotatably connected to the bottom end of the third diversion tube 21 through a rotary seal joint 24. The top and bottom of the fixed cylinder 8 are both of a conical structure.

[0059] The second diversion tube 20 on the left is hermetically connected to the first diversion tube 18. The first solenoid valve 19 is controlled to open, and the preliminarily mixed air and water inside the premixing cylinder 4 enter the generating tank 6 on the left. The tube shaft 7 and the fixed cylinder 8 are driven to rotate by the driving mechanism, and each rotary cutting blade 9 rotates accordingly, continuously performing rotary cutting on the air in the water to generate micro-nano bubbles. The second solenoid valve 22 on the left is in the open state, and the second solenoid valve 22 on the right is in the closed state. The generated micro-nano bubble water is discharged through the third diversion tube 21 and the discharge pipe 23.

[0060] The driving mechanism is arranged inside the tank body 1 and is used to drive the tube shaft 7 to rotate. The driving mechanism includes a sleeve shaft 25 rotatably connected inside the fixing plate 17 and a first motor 26 installed on the other side of the bottom of the premixing cylinder 4. On the outside of the output shaft of the first motor 26 and on the outside of the sleeve shaft 25, first gears 27 are fixedly sleeved. The two first gears 27 are meshed with each other. A toothed disc 29 is fixedly sleeved on the outside of the sleeve shaft 25, and a second gear 30 is fixedly sleeved on the outside of the tube shaft 7. The second gear 30 is meshed with the toothed disc 29.

[0061] By controlling the first motor 26 to drive the first gear 27 on the outside of its output shaft to rotate, through the meshing action between the two first gears 27, the sleeve shaft 25 is driven to rotate, and the toothed disc 29 rotates accordingly. Through the meshing action between the toothed disc 29 and the second gear 30, the tube shaft 7 is driven to rotate.

[0062] Adjusting mechanism, which includes a turntable 10 installed inside the tank body 1 and a transmission assembly for driving the turntable 10 to rotate. Both generating tanks 6 are installed on the top of the turntable 10. The transmission assembly includes a transmission shaft 31 fixedly connected to the center of the top of the turntable 10 and a second motor 32 arranged on one side of the first motor 26. The second motor 32 is also installed at the bottom of the premixing cylinder 4. The transmission shaft 31 passes through and is sleeved on the sleeve shaft 25 and is rotatably connected to the sleeve shaft 25. The output end of the second motor 32 is fixedly connected to the top end of the transmission shaft 31. An annular through groove 33 is formed inside the fixed plate 17. A slider 34 is also rotatably sleeved on the outer part of the pipe shaft 7. The slider 34 is slidably connected inside the through groove 33. The slider 34 also plays a role in supporting the middle part of the fixed plate 17.

[0063] When it is necessary to clean the scale inside the left generating tank 6, control the second motor 32 to drive the transmission shaft 31 to rotate clockwise by 180°. The turntable 10 rotates accordingly, thereby driving the two generating tanks 6 to revolve around the transmission shaft 31 as the center, swapping the positions of the two generating tanks 6, so that the generating tank 6 that was originally on the right rotates to the left. The oil cylinder 12 above the generating tank 6 also rotates accordingly. The second diversion pipe 20 at the top of this generating tank 6 is connected to the first diversion pipe 18 accordingly. The first solenoid valve 19 is in the closed state when swapping the generating tanks 6. After the swapping is successful, control the first solenoid valve 19 to open.

[0064] The first hidden descaling mechanism, which includes a plurality of oil guide grooves 11 formed inside the fixed cylinder 8, an oil cylinder 12 installed at the top end of the pipe shaft 7, a first piston 13 installed inside the oil cylinder 12, and a lifting assembly for driving the first piston 13 to lift and lower. A second piston 14 is installed inside the oil guide groove 11. One end of the rotary cutting blade 9 is connected to the outer wall of the second piston 14. The oil guide groove 11 is connected to the inside of the pipe shaft 7. The pipe shaft 7 is connected to the oil cylinder 12. The lifting assembly includes a plurality of first springs 28 fixedly connected to the inner wall of the top of the oil cylinder 12, a driven rod 35 fixedly connected to the top of the first piston 13, and a first cylinder 36 installed on the inner wall of the top of the tank body 1. The bottom end of the first spring 28 is fixedly connected to the top of the first piston 13. A driven disc 37 is installed at the top end of the driven rod 35. The extending end of the first cylinder 36 is fixedly connected to a driving disc 38. The driving disc 38 cooperates with the driven disc 37.

[0065] When the generating tank 6 on the left side and the oil cylinder 12 at its top rotate to the right side, one side of the driven disc 37 rotates to the top of the driving disc 38. At this time, by controlling the first cylinder 36 to drive the driving disc 38 to move upward, the driven disc 37 is driven to move upward accordingly. Thus, the first piston 13 is driven to move upward along the inner wall of the oil cylinder 12 through the driven rod 35, and the first spring 28 is compressed accordingly. A negative pressure is generated inside the oil cylinder 12, and the hydraulic oil inside the pipe shaft 7 is drawn into the oil cylinder 12 accordingly. The hydraulic oil inside the oil guide groove 11 flows toward the inside of the pipe shaft 7, so that each second piston 14 moves toward the pipe shaft 7 direction, and further drives each rotary cutting blade 9 to move into the fixed cylinder 8, removing the scale crystallized outside the rotary cutting blade 9, solving the problem that the scale outside the rotary cutting blade 9 easily affects the dynamic balance and surface shear force of the rotary cutting blade 9, and the method of cleaning the scale on the surface of the rotary cutting blade 9 does not affect its daily use;

[0066] When the first cylinder 36 drives the driving disc 38 to move downward and reset, through the rebounding force of the first spring 28, the first piston 13 is driven to move downward and reset, thereby guiding the hydraulic oil inside the oil cylinder 12 back into the pipe shaft 7. The hydraulic oil then enters the oil guide groove 11, driving each second piston 14 away from the pipe shaft 7, and further driving each rotary cutting blade 9 to move outward and reset toward the outside of the fixed cylinder 8.

[0067] The second hidden descaling mechanism includes a ring 15 installed inside the generating tank 6, a positioning block 16 installed on the inner wall of the top of the generating tank 6, and a plurality of elastic descaling components installed inside the ring 15. The elastic descaling components include a housing 39 fixedly connected to the inner wall of the ring 15, a scraping strip 40 slidably connected inside the housing 39, and a plurality of second springs 41 fixedly connected inside the housing 39; one end of the scraping strip 40 extends to the outside of the housing 39, and inclined grooves are provided at the top and bottom of one end of the scraping strip 40, and the inclined grooves are adapted to the conical surfaces at the top and bottom of the fixed cylinder 8; the other end of the second spring 41 is fixedly connected to the other end of the scraping strip 40. Two second cylinders 43 are installed on the inner wall of the top of the tank body 1, and the second cylinders 43 are not on the movement track of the oil cylinder 12. Electromagnets are installed inside the extending ends of the second cylinders 43. Two connecting channels 44 are installed on the top of the generating tank 6, a sealing plug 45 is installed inside the connecting channels 44, the sealing plug 45 is fixedly connected to the top of the ring 15, an iron block is installed inside the sealing plug 45, and the iron block cooperates with the electromagnet;

[0068] After the rotary cutting blade 9 moves into the fixed cylinder 8, by controlling the second cylinder 43 to extend, its extending end passes through the connecting channel 44 and abuts against the top of the sealing plug 45, and the electromagnet is energized to adsorb the sealing plug 45, so that the extending end of the second cylinder 43 establishes a connection with the ring 15. Thus, when the second cylinder 43 extends or contracts, the ring 15 can be driven to move;

[0069] After the second cylinder 43 is connected to the ring 15, as the second cylinder 43 continues to extend, it drives the ring 15 to move downward along the inner wall of the reaction tank 6, scraping off the scale on the inner wall of the reaction tank 6. At the same time, it drives each housing 39 to move downward. Through the elastic action of the second spring 41, one end of the scraping strip 40 moves downward along the outer wall of the fixed cylinder 8. Cooperating with the rotation of the fixed cylinder 8, the scale on the outer surface of the fixed cylinder 8 is cleaned. Similarly, by controlling the second cylinder 43 to shorten and driving the ring 15 to move upward, the scraping strip 40 can also be driven to clean the outer surface of the fixed cylinder 8. By cycling in this way, the outer surface of the fixed cylinder 8 is cleaned multiple times. By removing scale from the inner wall of the reaction tank 6 and the structure for supporting the rotary cutting blade 9, sufficient cleaning of all the structures inside the reaction tank 6 is achieved.

[0070] A plurality of positioning grooves 42 are formed on the outer wall of the positioning block 16, and one end of the scraping strip 40 is fitted with the positioning groove 42;

[0071] When the ring 15 is in the idle state, it is located on the inner wall at the top of the reaction tank 6. Through the rebounding force of the second spring 41, one end of the scraping strip 40 is inserted into the inside of the positioning groove 42, maintaining the stability of the entire ring 15 and other structures inside it. Thus, when the reaction tank 6 is used at the left working station, the presence of the ring 15 and the structures inside it will not affect the use effect of the rotary cutting blade 9;

[0072] Through two hidden scale removal methods, scale removal and cleaning of the internal structure of the reaction tank 6 can be carried out, enabling timely and sufficient scale removal treatment of the internal structure of the reaction tank 6, and neither affecting the daily use effect of the rotary cutting blade 9.

[0073] A scale guide pipe 46 is also installed at the bottom of the reaction tank 6, and a third solenoid valve 47 is installed on the scale guide pipe 46; a scale discharge pipe 48 is installed at the bottom on the other side of the tank body 1. The scale guide pipe 46 at the bottom of the reaction tank 6 on the right side is located above the scale discharge pipe 48; a cleaning pipe 49 is installed at the top on the other side of the tank body 1. The cleaning pipe 49 penetrates through the fixing plate 17. An electromagnet coil is also installed at the bottom end of the cleaning pipe 49. When the second diversion pipe 20 rotates to the bottom of the cleaning pipe 49, by energizing the electromagnet coil, the sealing iron ring is adsorbed, making the cleaning pipe 49 and the second diversion pipe 20 in sealed butt joint, and introducing the cleaning liquid into the reaction tank 6;

[0074] During scale removal, the cleaning liquid is injected into the reaction tank 6 on the right side through the cleaning pipe 49. At this time, the second solenoid valve 22 on the right side is in the closed state, and the third solenoid valve 47 on the right side is in the open state, so that the removed scale is discharged directionally through the scale guide pipe 46 and the scale discharge pipe 48.

[0075] Working principle: During use, air and tap water are injected into the mixing tube 5 through the air injection pipe 2 and the water injection pipe 3, so that the tap water and air are initially mixed inside the premixing cylinder 4. The first solenoid valve 19 is controlled to open, and the initially mixed air and water inside the premixing cylinder 4 enter the generating tank 6 on the left side. The tube shaft 7 and the fixed cylinder 8 are driven to rotate by the driving mechanism, and each cutting blade 9 rotates accordingly, continuously cutting the air in the water to generate micro-nano bubbles. The second solenoid valve 22 on the left side is in the open state, and the second solenoid valve 22 on the right side is in the closed state. The generated micro-nano bubble water is discharged through the third diversion pipe 21 and the discharge pipe 23. When it is necessary to clean the scale inside the generating tank 6 on the left side, the second motor 32 is controlled to drive the transmission shaft 31 to rotate clockwise by 180°. The turntable 10 rotates accordingly, thereby driving the two generating tanks 6 to revolve around the transmission shaft 31 as the center, swapping the positions of the two generating tanks 6, so that the generating tank 6 that was originally on the right side rotates to the left side, and the oil cylinder 12 above the generating tank 6 also rotates accordingly. The second diversion pipe 20 at the top of this generating tank 6 is connected to the first diversion pipe 18 accordingly. When swapping the generating tanks 6, the first solenoid valve 19 is in the closed state. After the swapping is successful, the first solenoid valve 19 is controlled to open. When the generating tank 6 on the left side and the oil cylinder 12 on its top rotate to the right side, one side of the driven disk 37 rotates to the top of the driving disk 38. At this time, the first cylinder 36 is controlled to drive the driving disk 38 to move upward, and the driven disk 37 is driven to move upward accordingly, thereby driving the first piston 13 to move upward along the inner wall of the oil cylinder 12 through the driven rod 35. The first spring 28 is compressed accordingly, a negative pressure is generated inside the oil cylinder 12, and the hydraulic oil inside the tube shaft 7 is pumped into the oil cylinder 12. The hydraulic oil inside the oil guide groove 11 flows toward the inside of the tube shaft 7, so that each second piston 14 moves toward the tube shaft 7, and further drives each cutting blade 9 to move toward the inside of the fixed cylinder 8, removing the scale crystallized outside the cutting blade 9, solving the problem that the scale outside the cutting blade 9 easily affects the dynamic balance and surface shear force of the cutting blade 9, and the method of cleaning the scale on the surface of the cutting blade 9 does not affect its daily use. After the cutting blade 9 is moved into the fixed cylinder 8, the second cylinder 43 is controlled to extend, and its extended end passes through the connection channel 44 and abuts against the top of the sealing plug 45, and the electromagnet is energized to adsorb the sealing plug 45, so that the extended end of the second cylinder 43 is connected to the ring 15. As the second cylinder 43 continues to extend, the ring 15 is driven to move downward along the inner wall of the generating tank 6, scraping the scale on the inner wall of the generating tank 6. At the same time, each housing 39 is driven to move downward. Through the elastic action of the second spring 41, one end of the scraping strip 40 moves downward along the outer wall of the fixed cylinder 8, and in cooperation with the rotation of the fixed cylinder 8, the scale on the outer surface of the fixed cylinder 8 is cleaned. Similarly, by controlling the second cylinder 43 to shorten and driving the ring 15 to move upward, the scraping strip 40 can also be driven to clean the outer surface of the fixed cylinder 8. By cycling in this way, the outer surface of the fixed cylinder 8 is cleaned multiple times.By descaling the inner wall of the generating tank 6 and the structure for supporting the rotary cutting blade 9, thorough cleaning of all the structures inside the generating tank 6 is achieved.
