[0056] The gas enters the interior of each stirring tube 20 in turn through the gas guide groove 23 and the gas guide cavity 22, and is discharged through the gas outlet at the bottom of each stirring tube 20 in turn. At the same time, the first motor 19 drives the first gear 21 outside its output shaft to rotate, and the engagement between the two first gears 21 drives the main shaft 18 to rotate, and then drives the stirring tubes 20 to rotate synchronously, so that the gas is evenly distributed in the water body, so that a uniform gas-water mixed liquid can be provided to the generating mechanism.

In this embodiment, there are four mixing barrels 26; a driven shaft 28 is rotatably connected inside the mixing barrel 26, a plurality of rotary cutting impellers 29 are fixedly sleeved on the outside of the driven shaft 28, a second gear 30 is fixedly connected to the top of the driven shaft 28, and the second gear 30 is meshed with the toothed disc 27, a liquid outlet pipe 31 is installed at the bottom of the mixing barrel 26, and a fourth solenoid valve 32 is installed on the liquid outlet pipe 31;

[0058] After the gas-water mixed liquid enters the mixing barrel 26, with the rotation of the main shaft 18, the toothed disc 27 rotates synchronously, and the meshing effect between the toothed disc 27 and the second gears 30 drives the driven shafts 28 to rotate. When the driven shafts 28 rotate, they drive the rotary cutting impellers 29 to rotate synchronously, repeatedly rotary cutting bubbles to obtain micro-nano bubble liquid, and the micro-nano bubble liquid is discharged through the liquid outlet pipe 31 by controlling the fourth solenoid valve 32 to open.

[0059] The guide-dividing mechanism is arranged between the primary mixing mechanism and the generating mechanism, and is used for continuously introducing the gas-water mixed liquid after the primary mixing into the generating mechanism.

A sixth solenoid valve 42 is installed on the conduit 34, wherein a small section of the top of the second conduit 34 is a retractable structure, so that when the electromagnet ring 35 adsorbs the iron ring 37, it can drive the iron ring 37 to move upward, so that the second sealing ring 38 is tightly attached to the first sealing ring. The driving assembly includes a second motor 39 installed on the top of the tank body 1 and an inner shaft 40 rotatably connected to the inside of the main shaft 18; the bottom end of the inner shaft 40 is fixedly connected to the top of the turntable 25; the top end of the inner shaft 40 is rotatably extended to the top of the bracket 15, and the inner shaft 40 and the outer part of the output shaft of the second motor 39 are fixedly sleeved with a third gear 41, and the two third gears 41 are meshed with each other;

[0060] The second motor 39 is controlled to drive the third gear 41 outside the output shaft to rotate, and the inner shaft 40 is driven to rotate through the meshing effect between the two third gears 41, and the turntable 25 rotates synchronously therewith, wherein the turntable 25 is controlled to pause every quarter turn, thereby driving the second conduits 34 at the tops of the four mixing cylinders 26 to rotate to the bottom of the first conduit 33 in turn. When one of the second conduits 34 rotates to the bottom of the first conduit 33, the electromagnet ring 35 is energized, and the electromagnet ring 35 has an opposite attraction effect on the iron ring 37 below it, so that the iron ring 37 is driven to quickly fit on the bottom of the electromagnet ring 35. In this process, the second sealing ring 38 is driven to quickly fit on the first sealing ring, so that the first conduit 33 and the second conduit 34 establish a sealed connection, at this time, the fifth solenoid valve 36 and the sixth solenoid valve 42 are opened, so that the uniform gas-water mixed liquid on the top of the partition 24 enters the interior of the mixing cylinder 26 through the first conduit 33 and the second conduit 34. After the injection is completed, the fifth solenoid valve 36 and the sixth solenoid valve 42 are controlled to be closed, and the electromagnet ring 35 is powered off, so that the first conduit 33 and the second conduit 34 are automatically separated, and then the turntable 25 is driven to rotate a quarter of a circle and then stop, and the second conduit 34 on the top of the next mixing cylinder 26 is driven to rotate to the bottom of the first conduit 33, and the above operation is repeated to inject the uniform gas-water mixed liquid on the top of the partition 24 into the interior of the mixing cylinder 26, and circulate in sequence to achieve continuous generation of micro-nano bubbles.

[0061] Working principle: When in use, water and gas are respectively injected into the tank body 1 through the water inlet pipe 2 and the gas injection pipe 3. After being filtered, the gas enters the interior of each stirring tube 20 in turn through the gas guide groove 23 and the gas guide cavity 22, and is discharged in turn through the gas outlet at the bottom of each stirring tube 20. At the same time, the first motor 19 drives the first gear 21 outside its output shaft to rotate, and the engagement between the two first gears 21 drives the main shaft 18 to rotate, and then drives the stirring tubes 20 to rotate synchronously, so that the gas is evenly distributed in the water body, so that a uniform gas-water mixed liquid can be provided to the generating mechanism, and the second motor 39 is controlled The third gear 41 outside the output shaft is driven to rotate, and the inner shaft 40 is driven to rotate through the meshing effect between the two third gears 41, and the turntable 25 rotates synchronously therewith, wherein the turntable 25 is controlled to pause every quarter turn, thereby driving the second conduits 34 at the tops of the four mixing cylinders 26 to rotate to the bottom of the first conduit 33 in turn. When one of the second conduits 34 rotates to the bottom of the first conduit 33, by energizing the electromagnet ring 35, the electromagnet ring 35 attracts the iron ring 37 below it, driving the iron ring 37 to quickly fit to the bottom of the electromagnet ring 35. In this process, the The second sealing ring 38 is driven to quickly close to the first sealing ring, so that the first conduit 33 and the second conduit 34 are sealed and connected. At this time, the fifth solenoid valve 36 and the sixth solenoid valve 42 are opened, so that the uniform gas-water mixed liquid on the top of the partition 24 enters the interior of the mixing cylinder 26 through the first conduit 33 and the second conduit 34. After the injection is completed, the fifth solenoid valve 36 and the sixth solenoid valve 42 are controlled to be closed, and the electromagnetic iron ring 35 is powered off, so that the first conduit 33 and the second conduit 34 are automatically separated, and the turntable 25 is driven to rotate a quarter of a turn and then stop, driving the second conduit 34 on the top of the next mixing cylinder 26 to rotate to the first conduit 34. The bottom of a conduit 33 is formed, and the above operation is repeated to inject the uniform gas-water mixed liquid on the top of the partition 24 into the mixing cylinder 26. After the gas-water mixed liquid enters the mixing cylinder 26, as the main shaft 18 rotates, the toothed disc 27 rotates synchronously, and the driven shafts 28 are driven to rotate through the meshing effect between the toothed disc 27 and the second gears 30. When the driven shaft 28 rotates, the rotary cutting impellers 29 are driven to rotate synchronously, and the bubbles are repeatedly rotary cut to obtain micro-nano bubble liquid. The cycle is carried out in sequence to realize the continuous generation of micro-nano bubble liquid, which solves the problem that the micro-nano bubble liquid can only be generated in batches in the prior art.
