[0004] Although the above-mentioned circulation cutting mixer in the prior art can stir and oxygenate the fermentation liquid well, the following problems still exist: the structural design of the equipment is difficult to adapt to the changes in different tank depths and water levels. Especially under complex outdoor fermentation conditions, the liquid level will inevitably change, and the height mismatch between the inlet and outlet and the liquid level will cause the circulation cutting aeration effect to decrease. Summary of the invention

[0009] Furthermore, the second connecting frame further comprises a vertical guide shaft, and the first transverse tube is provided with a guide opening adapted for the guide shaft, so as to ensure the stability of the adjustment process.

[0010] Furthermore, the guide tube includes multiple layers of sleeves, one of the outermost sleeve and the innermost sleeve is fixedly connected to the shell, the other of the outermost sleeve and the innermost sleeve is connected to the float, and a connecting mechanism is provided between adjacent sleeves, the connecting mechanism includes a guide groove and a guide block adapted to the guide groove along the length direction of the sleeve, and limit blocks are provided at both ends of the guide groove. The adaptability of the liquid level is adjusted by the telescopic movement of the sleeve, and the guide groove and the limit block ensure stable movement.

[0011] Furthermore, the sleeve is provided with flow guide holes in the circumference thereof, which optimize the water flow distribution and improve the operation efficiency of the equipment.

[0012] Furthermore, there is a space between adjacent sleeves for providing water flow, so as to avoid mutual blocking of the guide holes when different sleeves move relative to each other.

[0013] Furthermore, the aeration pipe is connected with an air intake control valve, and the aeration pipe is a floating aeration pipe.

[0019] Furthermore, in step S3, when the water level in the pool changes, the float rises and falls synchronously with the water level, driving the sleeve to move relative to it, so that the guide tube expands and contracts, keeping the height difference between the water inlet and the water surface unchanged, and always maintaining a suitable liquid level depth.

[0020] Beneficial effects: The float and the guide tube are connected by a lifting bracket. The relative position of the float and the water inlet can be adjusted by turning the rotating handle to drive the threaded rod to rotate, so that the water inlet of the guide tube is maintained at an appropriate liquid level depth during operation, ensuring the stability of circulation stirring and aeration; the guide tube adopts a multi-layer sleeve structure, so that the liquid level will not affect the use of the device when it is raised or lowered, which significantly improves the adaptability and ease of operation of the equipment.

[0028] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1-5 As shown, a circulating cutting aeration stirring device comprises an aeration mechanism 1, wherein the aeration mechanism 1 comprises a shell 11, wherein the shell 11 is provided with a motor 12, wherein the motor 12 is connected with a circulating stirring blade 13, wherein the shell 11 is connected with a guide pipe 14 and an aeration pipe 15 and is provided with a water outlet 16, wherein the space between the guide pipe 14 and the aeration pipe 15 forms a guide space, wherein a water inlet is provided at the top of the guide pipe 14, wherein the bottom of the guide pipe 14 is connected with the internal space of the shell 11, wherein an air flotation mechanism 2 is connected with the top of the guide pipe 14; wherein the air flotation mechanism 2 comprises a buoy 21, wherein the buoy 21 is connected with the guide pipe 14 via a lifting bracket, and wherein four buoys are provided in the present embodiment.

[0031] In this embodiment, the lifting bracket includes a first connecting frame 22 fixedly connected to the buoy 21 and a second connecting frame 23 fixedly connected to the guide tube 14; the first connecting frame 22 includes a first fixed seat 221, and a first cross tube 222 fixedly connected to the buoy 21 is fixedly arranged outwardly in the circumference of the first fixed seat 221, and a thread groove 223 is opened in the center of the first fixed seat 221; the second connecting frame 23 includes an annular fixed seat 231, and the annular fixed seat 231 is fixedly connected to the second cross tube 232, and the second cross tube 232 is rotatably connected to a vertical threaded rod 233, and the threaded rod 233 is threadedly connected to the thread groove 223, and a rotating handle 234 is fixedly arranged on the top of the threaded rod 233. By rotating the handle 234, the relative position of the threaded rod 233 in the threaded groove 223 can be adjusted, thereby changing the height difference between the first connecting frame 22 and the second connecting frame 23, and flexibly adjusting the relative height between the float 21 and the liquid surface, ensuring that the water inlet of the guide tube 14 is always in the best working position. It can be suitable for fermentation tanks of various depths, and can also be manually adjusted when the liquid level in the same fermentation tank changes significantly. However, the device needs to be removed from the tank body for adjustment. For ease of control, an additional motor can be added to achieve automatic adjustment of the height difference between the water inlet of the guide tube 14 and the liquid surface. A liquid level sensor can be added to the tank body to achieve automatic adjustment according to the liquid level height.

[0032] In this embodiment, the second connecting frame 23 further includes a vertical guide shaft 235, and the first transverse tube 222 is provided with a guide opening 224 adapted to the guide shaft 235. The guide shaft 235 provides additional support during the lifting and lowering adjustment process to avoid deviation or loosening, thereby improving the rigidity and operational stability of the overall structure. The addition of the guide structure makes the lifting and lowering adjustment more precise, ensuring that the relative position adjustment of the buoy 21 and the guide tube 14 is smooth and reliable.

[0033] In this embodiment, the guide tube 14 includes a multi-layer sleeve 141, one of the outermost sleeve and the innermost sleeve is fixedly connected to the shell 11, and the other sleeve of the outermost sleeve and the innermost sleeve is connected to the float 21. A connecting mechanism is provided between adjacent sleeves, and the connecting mechanism includes a guide groove 142 and a guide block 143 adapted to the guide groove along the length direction of the sleeve, and a limit block 144 is provided at both ends of the guide groove. The guide tube adopts a multi-layer sleeve structure to solve the influence of liquid level fluctuation on the operation of the device. The outermost sleeve or the innermost sleeve is fixedly connected to the shell, and the other end is connected to the float. Adjacent sleeves 141 are connected by the guide groove 142 and the guide block 143 along the length direction, and a limit block 144 is provided to prevent the sleeve 141 from over-expansion. The multi-layer sleeve 141 can automatically adjust the length as the float 21 rises and falls, ensuring that the water inlet and the liquid surface always maintain an appropriate height difference, and the device can operate stably regardless of how the liquid level changes.

[0034] In this embodiment, the sleeve 141 is provided with guide holes 145 in the circumference, and there is space between adjacent sleeves 141 for providing water flow. In order to enhance the water flow guiding effect, multiple guide holes 145 are designed in the circumference of the sleeve 141 to ensure the uniformity and smoothness of the liquid flow. Sufficient flow space is left between adjacent sleeves to reduce water flow resistance so that water can be more efficiently introduced into the device. The flow space can also avoid mutual obstruction between adjacent sleeves 141, which causes mutual influence and blockage of the guide holes 145 when the relative positions of the sleeves 141 change. The combined design of the guide holes and the flow space improves the water flow dynamics, improves the stirring and aeration effects, and significantly improves the oxygen utilization rate and fermentation efficiency.

[0035] In this embodiment, the aeration pipe 15 is connected to an air intake control valve, and the aeration pipe 15 is a floating aeration pipe. The floating aeration pipe can flexibly adapt to water level changes, and accurately adjust the gas injection amount through the air intake valve to ensure the uniformity of gas-liquid mixing. The floating design avoids the problem of reduced aeration efficiency of traditional fixed aeration pipes when the liquid level changes, and effectively improves the adaptability and operational stability of the device.

[0036] In this embodiment, a cushion 17 is installed at the bottom of the housing 11. The cushion 17 is designed at the bottom of the housing as a supporting structure. The cushion 17 not only provides anti-skid and anti-vibration functions for the equipment, but also reduces the corrosion and wear that may be caused by direct contact between the bottom of the equipment and the pool body, thereby extending the service life of the equipment.

[0037] Example 2

[0038] A working method of a circulating cutting aeration stirring device comprises the following steps:

[0039] S1. By rotating the rotating handle 234, the threaded rod 233 is driven to rotate, and the relative position of the threaded rod 233 and the thread groove 223 changes, thereby driving the relative height of the first connecting frame 22 and the second connecting frame 23 to change, thereby completing the relative position adjustment of the buoy 21 and the water inlet, so that the water inlet of the guide pipe 14 is maintained at a suitable liquid level depth during operation, ensuring the stability of the circulation stirring and aeration;

[0040] S2. Place the circulation cutting aeration stirring device in the tank body;

[0041] S3, start the motor 12 to drive the circulating stirring blades 13 to rotate. The circulating stirring blades 13 cut the water flow and drive the water flow to move, guide the water flow into the internal space of the shell 11 through the top opening of the guide pipe 14 and the side guide holes 145, and discharge the water from the water outlet 16 to form an annular water flow. At the same time, the aeration pipe 15 injects gas into the water flow in the shell 11 to achieve gas-liquid mixing and increase the dissolved oxygen in the water.

[0042] Furthermore, in step S3, when the water level in the pool changes, the float 21 rises and falls synchronously with the water level, driving the sleeve 141 to move relative to it, so that the guide tube 14 expands and contracts, keeping the height difference between the water inlet and the water surface unchanged, and always maintaining a suitable liquid level depth.

[0043] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
