[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In one embodiment, please refer to Figures 1 - 8, A sulfur autotrophic sewage treatment mechanism, including a mixing tank 1. An inlet is provided at the top of the mixing tank 1, and a drain is provided at the bottom of the mixing tank 1. These are all conventional structures and will not be elaborated in detail here. A rotating sleeve 6 is rotatably connected to the top of the mixing tank 1, and a vertically arranged main shaft 2 is slidably connected to the middle of the rotating sleeve 6. The sewage treatment mechanism further includes a driving mechanism 3 and a ventilation mechanism 4;

[0031] The driving mechanism 3 includes a support frame 16 provided at the upper end of the mixing tank 1. The support frame 16 is a U-shaped structure with an opening downward. The left and right ends of the support frame 16 are fixedly connected to the left and right sides of the top of the mixing tank 1. A lift plate 8 that can move up and down is slidably connected to the middle of the support frame 16. The middle of the lower surface of the lift plate 8 is rotatably connected to the upper end of the main shaft 2. A reciprocating driving component 13 is provided in the middle above the support frame 16. The reciprocating driving component 13 can push the lift plate 8 to move up and down. A stop rod 14 is provided above the main shaft 2. The stop rod 14 is horizontally arranged and perpendicular to the main shaft 2. A limiting plate 9 is provided in the middle of the main shaft 2. A return spring 7 is provided between the limiting plate 9 and the rotating sleeve 6 to make the up and down sliding of the main shaft 2 and the rotating sleeve 6 more stable. Spiral guide seats 5 are provided on the left and right sides of the upper surface of the mixing tank 1. The two spiral guide seats 5 are arranged in a circular symmetry with respect to the axis of the main shaft 2, and the spiral guide seats 5 are spiral structures, and the number of turns of the spiral guide seats 5 is less than half a turn. Therefore, a guide groove 10 is provided between the two spiral guide seats 5, and the left and right sides of the guide groove 10 are vertical planes. The width of the guide groove 10 is slightly larger than the diameter of the stop rod 14. Therefore, when the stop rod 14 is located in the guide groove 10, the stop rod 14 will move up and down along the guide groove 10, but when the stop rod 14 falls on the arc surface above the spiral guide seat 5, the stop rod 14 will rotate along the spiral guide seat 5;

[0032] The ventilation mechanism 4 includes a gas distribution block 28 provided at the lower end of the main shaft 2. The middle of the upper surface of the gas distribution block 28 is fixedly connected to the lower end of the main shaft 2, and the gas distribution block 28 is in a horizontal state. A plurality of air outlet nozzles 29 are evenly distributed on the lower surface of the gas distribution block 28. A one-way valve is provided inside the air outlet nozzle 29. Therefore, gas can only be discharged through the air outlet nozzle 29 through the gas distribution block 28. A gas guide sleeve 26 is vertically arranged at the bottom of the mixing tank 1. The upper part of the gas guide sleeve 26 is slidably connected to a gas guide rod 27. Both the gas guide rod 27 and the gas guide sleeve 26 are hollow structures. The upper end of the gas guide rod 27 is communicated with the gas distribution block 28, and the bottom of the gas guide sleeve 26 is unidirectionally communicated with the external environment of the mixing tank 1. Gas in the external environment can enter the inside of the gas guide sleeve 26. Therefore, when the gas guide rod 27 slides downward, the space inside the gas guide sleeve 26 is compressed, so that the gas inside the gas guide sleeve 26 enters the inside of the gas distribution block 28 through the gas guide rod 27, so that the air outlet nozzle 29 blows air outward, and oxygen enters the inside of the mixing tank 1.

[0033] In one case of this embodiment, a one-way air inlet nozzle 31 is arranged at the bottom of the mixing tank 1 inside the air guide sleeve 26, and the air flow of the one-way air inlet nozzle 31 flows towards the inside of the mixing tank 1. The one-way air inlet nozzle 31 is arranged at the central position of the bottom of the mixing tank 1. The one-way air inlet nozzle 31 can introduce the air in the external environment into the inside of the air guide sleeve 26, but the gas inside the air guide sleeve 26 cannot be discharged through the one-way air inlet nozzle 31. Therefore, as the air guide rod 27 moves up and down, the air in the external environment will intermittently enter the inside of the air guide sleeve 26 through the one-way air inlet nozzle 31.

[0034] In one case of this embodiment, a rotary joint 18 is arranged in the middle of the gas shunt block 28, and the rotary joint 18 is connected to the air guide rod 27. The rotary joint 18 is arranged in the middle of the lower surface of the gas shunt block 28 and is connected to the air guide rod 27 through the rotary joint 18. Therefore, even if the gas shunt block 28 rotates when moving up and down, the air guide rod 27 can always be kept in communication with the gas shunt block 28.

[0035] In one case of this embodiment, a diversion block 30 is arranged on one side of the gas shunt block 28 away from the air guide sleeve 26, and the cross section of the diversion block 30 is triangular. The effect of reducing resistance is achieved by arranging the triangular diversion block 30, so that when the gas shunt block 28 moves upward, the water flow resistance received by the gas shunt block 28 is reduced, and the energy consumption of the whole device is reduced.

[0036] In one case of this embodiment, a support beam 12 matching the guide groove 10 is arranged in the middle of the support frame 16, and a triangular reversing block 11 matching the stop rod 14 is arranged at the end of the support beam 12. The support beam 12 is arranged on the lower surface of the middle part of the support frame 16 in the front-back direction, and the triangular reversing block 11 is arranged at the front and rear ends of the lower surface of the support beam 12. When the stop rod 14 moves upward and contacts the triangular reversing block 11, the stop rod 14 will also rotate adaptively, so that the stop rod 14 rotates to the highest corresponding position of the spiral guide seat 5, so that the stop rod 14 will contact the higher part of the spiral guide seat 5 when it falls.

[0037] In a case of this embodiment, the reciprocating drive assembly 13 includes a push rod 15 slidably connected to the support frame 16. One end of the push rod 15 close to the mixing tank 1 is fixedly connected to the lifting plate 8. On both sides of the support frame 16, there are support plates 17. The end of the support plate 17 is rotatably connected to a rotating shaft 21. One end of the rotating shaft 21 close to the center of the support frame 16 is provided with a rotating disk 19. On the outer edge of the two rotating disks 19, there is a rotating rod 25. The middle of the rotating rod 25 is rotatably connected to one end of a support rod 20. The other end of the support rod 20 is rotatably connected to the end of the push rod 15 far from the mixing tank 1. A drive motor 22 is provided on the support plate 17. The output shaft of the drive motor 22 is fixedly connected to a first bevel gear 23. The first bevel gear 23 is meshed with a second bevel gear 24. The second bevel gear 24 is fixedly connected to the end of the rotating shaft 21. The push rod 15 is vertically slidably connected to the middle of the support frame 16. On the left and right sides of the upper end of the support frame 16, the support plates 17 are vertically arranged. The first bevel gear 23 and the second bevel gear 24 can achieve the effect of a speed reducer, so that the drive motor 22 can drive the rotating disk 19 to rotate, thereby making the push rod 15 move up and down, that is, making the main shaft 2 move up and down.

[0038] During the implementation of this embodiment, first, the sewage and treatment agent to be processed are introduced into the mixing tank 1, and support pads are arranged at the bottom of the mixing tank 1, so that enough space is left at the bottom of the mixing tank 1 to achieve the effect of air intake.

[0039] Start the drive motor 22. The output shaft of the drive motor 22 drives the rotating shaft 21 to rotate through the meshed first bevel gear 23 and second bevel gear 24. The rotating shaft 21 drives the rotating disk 19 to rotate. The rotating disk 19 pushes the push rod 15 to move up and down through the support rod 20, so that the lifting plate 8 moves up and down with the push rod 15. When the lifting plate 8 moves downward, the main shaft 2 moves downward with the lifting plate 8. The shift lever 14 on the main shaft 2 will fall above the spiral guide seat 5. The shift lever 14 rotates along the arc surface of the spiral guide seat 5. From a top view, at this time, the main shaft 2 rotates counterclockwise. When the shift lever 14 rotates into the guide grooves 10 of the two spiral guide seats 5, the shift lever 14 stops rotating. When the main shaft 2 moves upward, the shift lever 14 first moves vertically upward along the guide groove 10. However, when the shift lever 14 moves to the lower surface of the triangular reversing block 11, the shift lever 14 will rotate slightly counterclockwise by a certain angle again, so that the shift lever 14 will move to above the higher position of the spiral guide seat 5 again. Thus, with the up and down movement of the main shaft 2, the main shaft 2 rotates counterclockwise by nearly 90 degrees every time it moves downward. When the main shaft 2 moves upward, the main shaft 2 basically remains stationary, so that the main shaft 2 realizes the effect of intermittent rotation, and during each rotation, it is in the process of moving downward.

[0040] When the main shaft 2 moves downward, the air guide rod 27 is inserted into the inside of the air guide sleeve 26. At this time, the gas inside the air guide sleeve 26 moves to the gas distribution block 28 through the air guide rod 27, so that the air outlet nozzle 29 conducts air guiding treatment into the inside of the mixing tank 1. And at this time, the gas distribution block 28 rotates along with the main shaft 2, so that the air outlet nozzle 29 can conduct air ventilation treatment on the bottom of the mixing tank 1. When the air guide rod 27 moves upward along with the gas distribution block 28, the gas in the external environment will enter the inside of the air guide sleeve 26 through the one-way air inlet nozzle 31, so that the gas in the external environment can intermittently enter the inside of the air guide sleeve 26, and the air outlet nozzle 29 can realize the rotation ventilation treatment every time it falls.

[0041] The present invention is applicable to a sulfur autotrophic sewage treatment mechanism. In this application, through the cooperation of the stop rod 14 and the spiral guide seat 5, when the air outlet nozzle 29 moves downward for ventilation each time, it also makes a rotational movement, so that the air outlet nozzle 29 can conduct air ventilation treatment on different positions at the bottom of the mixing tank 1. And during the rotation of the gas distribution block 28, stirring treatment is also realized, thereby improving the dissolved oxygen efficiency.

[0042] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed claims.
