DETAILED DESCRIPTION

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: an industrial wastewater anoxic tank with a pneumatic stirring mechanism, comprising an anoxic tank 1, a fixed cylinder 3 is fixedly connected inside the anoxic tank 1, a fixed frame 2 is fixedly connected to the surface of the fixed cylinder 3, a mesh plate 5 is fixedly connected to the surface of the fixed frame 2, a rotating tube 4 is rotatably connected inside the fixed cylinder 3, a connecting tube 6 arranged equidistantly is fixedly connected to the surface of the rotating tube 4, and through holes 7 arranged equidistantly are opened on the surface of the connecting tube 6, a turbine blade 15 is fixedly connected to the surface of the rotating tube 4 located inside the fixed cylinder 3, and a through hole 7 is also opened on the surface of the fixed cylinder 3.

[0024] A fan is arranged inside the fixed frame 2, and an air outlet of the fan is fixedly connected to the fixed tube 3. The fan is an existing structure and will not be explained any more.

[0025] When the fan is started, the outside air enters the fixed frame 2 through the mesh plate 5 under the suction of the fan, and then the air flows into the rotating tube 4 under the blowing of the fan, and the air enters the connecting tube 6 through the rotating tube 4, and is ejected through the through holes 7 on the surfaces of the rotating tube 4 and the connecting tube 6. The ejected gas impacts the sewage inside the anoxic tank 1. At the same time, since the surface of the fixed cylinder 3 is also provided with a through hole 7, and the airflow flowing inside the fixed cylinder 3 drives the rotating tube 4 to rotate, and then the rotating tube 4 drives the connecting tube 6 to rotate. By starting the fan, the device stirs the sewage inside the anoxic tank 1, and the sewage inside the anoxic tank 1 is moved, so that the sewage is prevented from being stationary and the sludge attached therein sinks to the bottom, and the mud and water are prevented from being stratified. At the same time, the sewage inside the anoxic tank 1 is stirred and mixed by the rotation of the connecting tube 6, so that the sewage is evenly mixed.

[0026] A fixed block 8 is fixedly connected to the surface of the rotating tube 4, and the fixed block 8 is arranged in a hexagonal shape. A connecting rod 9 in a circumferential array is fixedly connected to the surface of the fixed block 8. A fixed block 3 11 is fixedly connected to the bottom of the anoxic pool 1. A sliding block 12 is slidably connected inside the fixed block 3 11. A fixed block 2 10 is fixedly connected to the surface of the sliding block 12, and the surface of the fixed block 2 10 is arranged in an inclined shape, and the position of the fixed block 2 10 corresponds to the position of the connecting rod 9. A connecting rod 2 16 is fixedly connected to the surface of the connecting rod 2 16. Slide plates 13 arranged equidistantly are fixedly connected to the surface of the fixed block 3 11. A spring 17 is fixedly connected to the inside of the fixed block 3 11, and the end of the spring 17 away from the fixed block 3 11 is fixedly connected to the sliding block 12.

[0027] When the rotating tube 4 rotates, the rotating tube 4 drives the fixed block 8 and the connecting rod 9 to rotate, and the connecting rod 9 rotates to squeeze the surface of the fixed block 2 10, and because the surface of the fixed block 2 10 is inclined, the fixed block 2 10 is forced to drive the sliding block 12 to move, and the sliding block 12 moves to shrink toward the inside of the fixed block 3 11, so that the sliding block 12 drives the connecting rod 2 16 to move, and the connecting rod 2 16 drives the slide plate 13 to move, and the bottom of the anoxic tank 1 is moved. At the same time, the sliding block 12 moves to squeeze the spring 17. When the connecting rod 19 no longer squeezes the fixed block 2 10, the sliding block 12 drives the connecting rod 2 16 and the slide plate 13 to reset and poke the sludge again under the elastic force of the spring 17, and then the sludge that has sunk to the bottom of the anoxic tank 1 is pried, so that the sludge floats into the water again, avoiding the stratification of the sludge and sewage.

[0028] The surface of the slide plate 13 is rotatably connected to a toggle plate 14 , the shaft of the toggle plate 14 is fixedly connected to a gear 18 , the inner wall of the anoxic pool 1 is fixedly connected to a rack 19 , and the surface of the rack 19 is meshed with the surface of the gear 18 .

[0029] When the slide plate 13 moves, the slide plate 13 drives the toggle plate 14 and the gear 18 to move. Since the gear 18 is meshed and connected with the rack 19, the toggle plate 14 will rotate during the movement, thereby breaking up the sludge floated by the slide plate 13 again, further mixing the sludge with the sewage, avoiding the stratification of the sewage and the sludge, and further improving the use effect of the device.

[0030] Working principle: The outside air enters the interior of the fixed frame 2 through the mesh plate 5 under the suction of the fan. Under the blowing of the fan, the air will flow into the interior of the rotating tube 4. The air will enter the interior of the connecting tube 6 through the rotating tube 4 and be ejected from the through hole 7. The ejected gas impacts the sewage inside the anoxic pool 1. The airflow flowing inside the fixed tube 3 will drive the rotating tube 4 to rotate, and then the rotating tube 4 drives the connecting tube 6 to rotate.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
