DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 2 The utility model provides an embodiment: a cyclone mixing aeration sewage treatment equipment, including a treatment pool 1, an aeration pipe 2 is fixedly connected to the inside of the treatment pool 1, a base 3 is fixedly connected to the upper end of the aeration pipe 2, an air outlet is opened on the outer side of the upper end of the base 3, and air is supplied to the aeration pipe 2 by an air supply machine of the aeration system. The gas flows into the inside of each base 3 through the aeration pipe 2 and then sprays upward through the air outlet. An aeration head 4 is fixedly connected to the upper end of the base 3, and a bubble sawtooth is fixedly connected to the outer surface of the aeration head 4. When the gas flows out through the air outlet, due to the inverted cone-shaped structure of the aeration head 4 and the setting of the bubble breaking sawtooth, it can be fully aerated and a large number of bubbles with small diameters can be formed, so that the sewage can be effectively treated and the gas-liquid mixing effect in the sewage can be improved.

[0034] Reference Figure 3-Figure 5 A fixing frame 5 is fixedly connected to the inside of the base 3, and a rotating shaft 6 is rotatably connected to the upper end of the fixing frame 5. A spiral blade 7 is fixedly connected to the outer side of the rotating shaft 6. The rotating shaft 6 can support and limit the spiral blade 7. A follower unit is arranged at the upper end of the inner part of the base 3. When the gas flows upward through the bottom end of the base 3, it will hit the spiral blade 7, so that the spiral blade 7 connects to the rotating shaft 6 to rotate. When the spiral blade 7 rotates, it can drive the passing gas to rotate, so that the gas can flow upward in a spiral, so that the gas moves a shorter distance in the same time after flowing out through the outlet, and can be fully mixed with the sewage, thereby enhancing the aeration treatment effect of the sewage.

[0035] The follower unit includes a lower cone shell 71, which is arranged at the inner upper end of the base 3. The lower cone shell 71 is arranged in a cone shell structure with the tip facing downward. The outer wall of the lower cone shell 71 fits the inner wall of the base 3. When the gas forms a vortex airflow through the spiral blades 7 and flows downward, it pushes the lower cone shell 71 to move the lower cone shell 71 upward. The inner bottom surface of the lower cone shell 71 is fixedly connected with a moving cylinder 72. When the lower cone shell 71 moves, it can drive the moving cylinder 72 to move synchronously. The bottom end surface of the moving cylinder 72 is provided with an exhaust hole 73, and the air inside the moving cylinder 72 can be discharged through the exhaust hole 73. The upper outer side of the moving cylinder 72 is plugged with a fixed cylinder 7 4. The movement of the movable cylinder 72 and the lower cone shell 71 can be guided and limited by the provided fixed cylinder 74 to prevent the lower cone shell 71 from being offset and stuck inside the base 3 and unable to move. The upper end of the fixed cylinder 74 is fixedly connected to the bottom end of the aeration head 4. When the lower cone shell 71 moves upward under the push of the airflow, the movable cylinder 72 can be driven to move synchronously. The movement of the lower cone shell 71 is guided and limited by the cooperation of the movable cylinder 72 and the fixed cylinder 74 to prevent the lower cone shell 71 from being offset. At the same time, the air inside the movable cylinder 72 and the fixed cylinder 74 can be discharged through the exhaust hole 73 to prevent the air inside the movable cylinder 72 and the fixed cylinder 74 from being compressed and hindering the movement of the lower cone shell 71.

[0036] The outer side of the lower cone shell 71 is fixedly connected with a connecting block 75, and the outer side of the connecting block 75 is fixedly connected with a sealing ring 76. When the lower cone shell 71 moves, the sealing ring 76 can be driven to move synchronously by the connecting block 75. The sealing ring 76 is sleeved on the outer side of the base 3. In the initial state, the sealing ring 76 is sleeved on the outer side of the air outlet. At this time, the air outlet can be sealed to prevent impurities in the sewage from entering the base 3 and affecting the gas circulation or blocking the air outlet. A vertical through groove 77 is provided on the outer surface of the base 3. The connecting block 75 is slidably connected to the inside of the vertical through groove 77. The connecting block 75 can perform linear motion in the vertical through groove 77 in the up and down directions. When the gas enters the base 3 and surges upward, it will press the lower cone shell 7 1 is lifted up, so that the lower cone shell 71 drives the sealing ring 76 to move upward, thereby opening the air outlet. When aeration is completed, the lower cone shell 71 and the sealing ring 76 will automatically reset under the action of gravity to restore the sealing of the air outlet, thereby preventing impurities in the sewage from clogging the air outlet or entering the base 3 to affect the gas flow. The upper end of the aeration head 4 is fixedly connected with a top cone shell 8. When the gas flows upward through the aeration head 4, the sewage can be moved. At this time, a vacuum bag will be formed on the outside of the aeration head 4, and the water flow above the aeration head 4 can flow downward along the inclined surface of the top cone shell 8 to the outside of the aeration head 4 for sufficient aeration treatment, thereby preventing a small part of the sewage from being fully mixed with the gas due to the planar structure setting at the top of the aeration head 4.

[0037] Reference Figure 1 and Figure 6 A guide groove 9 is provided on the right side surface of the treatment pool 1, and a mounting frame 10 is fixedly connected to the right inner wall surface of the treatment pool 1. A guide rod 11 is inserted into the guide groove 9. The guide rod 11 can perform linear motion in the up and down directions inside the guide groove 9 and can be pulled out from the guide groove 9. A collection box 12 is fixedly connected to the left end of the guide rod 11. The right side surface of the collection box 12 is arranged in an open structure. The sewage entering the pool body through the water inlet on the right side of the treatment pool 1 will completely enter the collection box 12. The right side surface of the collection box 12 is in contact with the treatment pool 1. The inner wall surfaces on the right side fit each other, and the bottom end of the collecting box 12 is plugged into the inside of the mounting frame 10. The mounting frame 10 can support and limit the bottom end of the collecting box 12 to improve the stability of the collecting box 12. The left surface of the collecting box 12 is provided with a filter hole 13, and the filter hole 13 can filter the sewage entering the collecting box 12 to prevent larger impurities in the sewage from entering the treatment tank 1 and causing the sewage to hit the base 3 or the aeration head 4 and cause damage to the aerator. When it is necessary to clean the impurities, just lift up the collecting box 12 to disassemble it, which is easy to operate.

[0038] Working principle: air is supplied to the aeration pipe 2 through the aeration system's air supply machine, and the gas flows into each base 3 through the aeration pipe 2. During the upward flow of the gas inside the base 3, the gas will hit the spiral blade 7, causing the spiral blade 7 to rotate, thereby forming a vortex airflow in the upward flow of the gas, so that the airflow can better contact with the sewage and improve the aeration treatment effect. Subsequently, the airflow can push the lower cone shell 71, so that the lower cone shell 71 drives the sealing ring 76 to move upward to open the air outlet, and the vortex gas can flow along the inclined surface of the lower cone shell 71 through the air outlet to the upper end of the outer side of the base 3 to contact the sewage for aeration. After the aeration is completed, the lower cone shell 71 and the sealing ring 76 will move downward and reset under the action of gravity, and the air outlet will be sealed to prevent impurities in the sewage from clogging the air outlet or entering the base 3 to affect the gas flow.
