Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a micro-nano bubble shower generator. Background Art

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

[0003] When the existing micro-nano bubble generator is used under the alkaline water conditions in the north, a large amount of scale is easily generated inside it. Even if the rotary cutting blades are rotating, vortices are easily formed on the back and root areas of the rotary cutting blades, resulting in a decrease in flow rate and crystallization into scale. As the scale increases, the dynamic balance of the rotary cutting blades will be affected, resulting in increased noise and energy consumption. It will also lead to insufficient shear force on the surface of the rotary cutting blades, affecting the effect of micro-nano bubble generation. It is difficult to clean the scale inside the existing generator, and it is difficult to perform high-frequency cleaning.

[0023] The regulating mechanism includes a turntable 10 installed inside the tank body 1 and a transmission assembly for driving the turntable 10 to rotate. The two generating tanks 6 are installed on the top of the turntable 10. The transmission assembly includes a transmission shaft 31 fixedly connected to the top center of the turntable 10 and a second motor 32 arranged on one side of the first motor 26.

The slider 34 is slidably connected to the inside of the through groove 33, and the slider 34 also plays a role in supporting the middle part of the fixed plate 17; When it is necessary to clean the scale inside the left generating tank 6, the second motor 32 is controlled to drive the transmission shaft 31 to rotate 180° clockwise, and the turntable 10 rotates accordingly, thereby driving the two generating tanks 6 to revolve around the transmission shaft 31, swapping the positions of the two generating tanks 6, so that the generating tank 6 previously on the right rotates to the left, and the oil cylinder 12 above the generating tank 6 also rotates accordingly, and the second guide tube 20 on the top of the generating tank 6 is connected to the first guide tube 18. When the generating tank 6 is replaced, the first solenoid valve 19 is in a closed state. After the replacement is successful, the first solenoid valve 19 is controlled to open.

[0024] The first hidden descaling mechanism includes a plurality of oil guide grooves 11 provided inside the fixed cylinder 8, an oil cylinder 12 installed at the top 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 rise and fall. 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, and 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, and a driven disc 37 is installed at the top of the driven rod 35; an active disc 38 is fixedly connected to the extended end of the first cylinder 36, and the active disc 38 cooperates with the driven disc 37; When the generating tank 6 on the left and the oil cylinder 12 on the top thereof rotate to the right, one side of the driven disc 37 rotates to the top of the active disc 38. At this time, the active disc 38 is driven to move upward by controlling the first cylinder 36, and the driven disc 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, and the first spring 28 is compressed accordingly, and negative pressure is generated inside the oil cylinder 12. The hydraulic oil inside the pipe shaft 7 is then drawn into the oil cylinder 12, and 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 direction of the pipe shaft 7, and then drives each rotary cutting blade 9 to move toward the inside of the fixed cylinder 8, and removes the crystallized scale on the outside of the rotary cutting blade 9, thereby solving the problem that the scale on the outside of 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 will not affect its daily use; When the first cylinder 36 drives the active disc 38 to move downward and reset, the first piston 13 is driven to move downward and reset through the rebound force of the first spring 28, thereby guiding the hydraulic oil inside the oil cylinder 12 back to the inside of the pipe shaft 7, and the hydraulic oil then enters the inside of 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 toward the outside of the fixed cylinder 8 and reset.

[0025] The second hidden descaling mechanism comprises 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 scraping components installed inside the ring 15. The elastic scraping components comprise a shell 39 fixedly connected to the inner wall of the ring 15, a scraping strip 40 slidably connected inside the shell 39, and a plurality of second springs 41 fixed inside the shell 39; one end of the scraping strip 40 extends to the outside of the shell 39, and the top and bottom of one end of the scraping strip 40 are both provided with an inclined groove, and the inclined groove is connected to the fixed cylinder. 8 The conical surface of the top and bottom are adapted; the other end of the second spring 41 is fixedly connected to the other end of the scraper strip 40, two second cylinders 43 are installed on the inner wall of the top of the tank body 1, the second cylinders 43 are not on the motion track of the oil cylinder 12, and an electromagnet is installed inside the extended end of the second cylinder 43, and two connecting channels 44 are installed on the top of the generating tank 6, and a sealing plug 45 is installed inside the connecting channel 44, and the sealing plug 45 is fixedly connected to the top of the ring 15, and an iron block is installed inside the sealing plug 45, and the iron block cooperates with the electromagnet; After the rotary cutting blade 9 moves into the fixed cylinder 8, the second cylinder 43 is controlled to extend, and its extended 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 extended end of the second cylinder 43 is connected to the ring 15, so that when the second cylinder 43 is extended or shortened, the ring 15 can be driven to move; After the second cylinder 43 establishes a connection with 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 generating tank 6, scrapes off the scale on the inner wall of the generating tank 6, and drives each shell 39 to move downward at the same time. Through the elastic action of the second spring 41, one end of the scraper 40 is moved downward along the outer wall of the fixed cylinder 8, and cooperates with the rotation of the fixed cylinder 8 to clean the scale on the outer surface of the fixed cylinder 8. Similarly, by controlling the shortening of the second cylinder 43 to drive the ring 15 to move upward, the scraper 40 and the outer surface of the fixed cylinder 8 can also be driven to clean. In this cycle, 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, all the internal structures of the generating tank 6 are fully cleaned.

[0026] A plurality of positioning grooves 42 are formed on the outer wall of the positioning block 16, and one end of the scraper strip 40 is matched with the positioning groove 42; When the ring 15 is in an idle state, it is located on the inner wall of the top of the generator tank 6. Through the rebound force of the second spring 41, one end of the scraper strip 40 is inserted into the interior of the positioning groove 42 to maintain the stability of the entire ring 15 and other structures inside it. Therefore, when the generator tank 6 is located at the left station for use, the existence of the ring 15 and its inner structure will not affect the use effect of the rotary cutting blade 9. By using two hidden descaling methods, the internal structure of the generator tank 6 is descaled and cleaned, and the internal structure of the generator tank 6 can be descaled in a timely and sufficient manner without affecting the daily use effect of the rotary cutting blade 9.

[0027] A scale guide pipe 46 is also installed at the bottom of the generating 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 of the other side of the tank body 1, and the scale guide pipe 46 at the bottom of the generating tank 6 on the right side is located at the top of the scale discharge pipe 48; a cleaning pipe 49 is installed at the top of the other side of the tank body 1, and the cleaning pipe 49 penetrates the fixed plate 17, and an electromagnet ring is also installed at the bottom of the cleaning pipe 49. When the second flow guide pipe 20 rotates to the bottom of the cleaning pipe 49, the sealing iron ring is adsorbed by energizing the electromagnet ring, so that the cleaning pipe 49 and the second flow guide pipe 20 are sealed and connected, and the cleaning liquid is introduced into the generating tank 6; During descaling, cleaning liquid is injected into the right generating tank 6 through the cleaning pipe 49. At this time, the second solenoid valve 22 on the right is in a closed state, and the third solenoid valve 47 on the right is in an open state, so that the cleaned scale is discharged in a direction through the scale guide pipe 46 and the scale discharge pipe 48.

[0028] Working principle: When in 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 preliminarily mixed inside the premixing tube 4, and the first solenoid valve 19 is controlled to be opened, and the air and water after the initial mixing inside the premixing tube 4 enter the generating tank 6 on the left, and the tube shaft 7 and the fixed tube 8 are driven to rotate by the driving mechanism, and each rotary cutting blade 9 rotates accordingly, and the air in the water is continuously rotary cut to generate micro-nano bubbles. The second solenoid valve 22 on the left is in an open state, and the second solenoid valve 22 on the right is in a closed state. The generated micro-nano bubble water is discharged through the third guide pipe 21 and the discharge pipe 23. When it is necessary to clean the scale inside the generating tank 6 on the left, the transmission shaft 31 is driven in the same direction by controlling the second motor 32. When the hour hand rotates 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 previously on the right rotates to the left, and the oil cylinder 12 above the generating tank 6 also rotates accordingly, and the second guide tube 20 on the top of the generating tank 6 is connected to the first guide tube 18 accordingly. When the generating tank 6 is swapped, the first solenoid valve 19 is in a closed state. After the swap is successful, the first solenoid valve 19 is controlled to open, and when the generating tank 6 on the left and the oil cylinder 12 on its top rotate to the right, one side of the driven disc 37 rotates to the top of the active disc 38. At this time, the active disc 38 is driven upward by controlling the first cylinder 36, and the driven disc 37 is driven upward accordingly, thereby 35 drives the first piston 13 to move upward along the inner wall of the oil cylinder 12, and the first spring 28 is compressed accordingly, and negative pressure is generated inside the oil cylinder 12, and the hydraulic oil inside the pipe shaft 7 is sucked into the oil cylinder 12, and 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, and then drives each rotary cutting blade 9 to move toward the inside of the fixed cylinder 8, and removes the scale crystallized on the outside of the rotary cutting blade 9, which solves the problem that the scale on the outside of 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 will not affect its daily use. After the rotary cutting blade 9 moves into the inside of the fixed cylinder 8, the second cylinder 43 is controlled to extend, and its extended end passes through the connecting channel 4 4 abuts against the top of the sealing plug 45, and energizes the electromagnet to absorb the sealing plug 45, so that the extended end of the second cylinder 43 is connected with 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 to scrape off the scale on the inner wall of the generating tank 6, and at the same time, the shells 39 are driven to move downward. Through the elastic action of the second spring 41, one end of the scraper 40 is moved downward in contact with the outer wall of the fixed cylinder 8, and the scale on the outer surface of the fixed cylinder 8 is cleaned in coordination with the rotation of the fixed cylinder 8. Similarly, by controlling the shortening of the second cylinder 43 to drive the ring 15 to move upward, the scraper 40 can also be driven to clean the outer surface of the fixed cylinder 8. In this way, the outer surface of the fixed cylinder 8 is cleaned multiple times.By descaling the inner wall of the generator tank 6 and the structure for supporting the rotary cutting blades 9, all the structures inside the generator tank 6 are fully cleaned.
