[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anaerobic tank accelerated reaction device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3 An anaerobic digester acceleration device includes a digester body 1. A rotating hole is provided at the top of the digester body 1, and a connecting pipe 5 is rotatably connected to the rotating hole via a bearing. A power assembly for driving the connecting pipe 5 to rotate is provided on the outer wall of the top of the digester body 1. Multiple evenly distributed gas distribution pipes 11 are welded to the outer circumference of the connecting pipe 5. Multiple evenly distributed nozzles 8 are bolted to the outer sides of each gas distribution pipe 11. A rotating shaft 12 is rotatably connected to the outer circumference of the connecting pipe 5 between two adjacent gas distribution pipes 11 via a bearing. An impeller 13 is keyed to one end of the rotating shaft 12. A spiral plate 9 is welded to the outer circumference of the rotating shaft 12. The carbon source is added into the connecting pipe 5. The carbon source in the connecting pipe 5 will enter the gas distribution pipe 11 and be sprayed out through the nozzle 8, so that the carbon source enters the pool body 1. When the nozzle 8 sprays out the carbon source, it will blow the impeller 13 to rotate. The impeller 13 will drive the rotating shaft 12 to rotate. The rotating shaft 12 will drive the spiral plate 9 to rotate. At this time, the spiral plate 9 will push the liquid at the center of the pool body 1 to the edge of the pool body 1. When the liquid at the center flows to the edge, it will cause the liquid at the edge to flow, so that the liquid flows in the pool body 1.

[0023] Inside the pool body 1, at each corner, a flow guide frame 15 is fixed with bolts. On one side of the flow guide frame 15, multiple upwardly inclined arc-shaped plates 16 are welded. During the process of the carbon source entering the pool body 1, the carbon source in the connecting pipe 5 will enter the gas distribution pipe 11 and be sprayed out through the nozzle 8, so that the carbon source enters the pool body 1. When the nozzle 8 sprays out the carbon source, it will blow the impeller 13 to rotate. The impeller 13 will drive the rotating shaft 12 to rotate, and the rotating shaft 12 will drive the spiral plate 9 to rotate. At this time, the spiral plate 9 will push the liquid at the center of the pool body 1 to the edge of the pool body 1. When the liquid at the center flows to the edge, it will cause the liquid at the edge to flow, so that the liquid flows in the pool body 1. The connecting pipe 5 is driven to rotate by the power component. The pool body 1 is provided with a support component to support the connecting pipe 5.

[0024] In this utility model, the power assembly includes a fixed frame 2, which is fixed to the top outer wall of the pool body 1 by bolts. A motor 7 is fixed to one side of the fixed frame 2 by bolts. One end of the output shaft of the motor 7 passes through the fixed frame 2 and is fixed to a worm gear 3 by a coupling. A worm wheel 6 is keyed to the outside of the connecting pipe 5 above the pool body 1, and the worm wheel 6 meshes with the worm gear 3. When the motor 7 is started, the motor 7 will drive the worm gear 3 to rotate, the worm gear 3 will drive the worm wheel 6 to rotate, and the worm wheel 6 will drive the connecting pipe 5 to rotate. The supporting component is a base 10, which is fixed to the bottom of the pool body 1 by bolts. The connecting pipe 5 and the base 10 are rotatably connected by bearings. The base 10 supports the connecting pipe 5, ensuring that the connecting pipe 5 remains vertical during rotation and preventing the connecting pipe 5 from shaking during rotation.

[0025] In particular, the inner walls of the pool body 1 are equipped with multiple evenly distributed heating wires 14. When using the anaerobic pool in winter, the heating wires 14 can be used to heat the inside of the anaerobic pool to maintain a suitable temperature, so as to ensure the activity of anaerobic bacteria, improve the removal rate of organic matter and the amount of gas produced, and ensure the normal operation of the anaerobic pool in winter. The top of the connecting pipe 5 is rotatably connected to an external pipe 4, which can be connected to an external carbon source conveying device to add carbon source into the connecting pipe 5. The two sides of the pool body 1 are welded with liquid inlet pipes near the top, and the one side of the pool body 1 is welded with a liquid outlet pipe at the bottom. A valve is provided on the outside of the liquid outlet pipe.

[0026] Working principle: When needed, the carbon source is added to the connecting pipe 5 through the external pipe 4. The carbon source in the connecting pipe 5 enters the gas distribution pipe 11 and is sprayed out through the nozzle 8, allowing the carbon source to enter the pool body 1. When the carbon source is sprayed out by the nozzle 8, it blows the impeller 13 to rotate. The impeller 13 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the spiral plate 9 to rotate. At this time, the spiral plate 9 pushes the liquid at the center of the pool body 1 towards the edge of the pool body 1. When the liquid at the center flows towards the edge, it causes the liquid at the edge to flow, thus making the liquid flow in the pool body 1. At the same time, the motor 7 is started. The motor 7 drives the worm gear 3 to rotate, the worm gear 3 drives the worm wheel 6 to rotate, the worm wheel 6 drives the connecting pipe 5 to rotate, and the connecting pipe 5 drives the gas distribution pipe 11 and the rotating shaft 12 to rotate. When the rotating shaft 12 rotates to align with the corner of the tank body 1, the liquid at the corner will flow under the action of the spiral plate 9. At the same time, the liquid at the corner will flow upward under the action of the guide frame 15 and the arc plate 16. Meanwhile, the nozzle 8 on the gas distribution pipe 11 can evenly distribute the carbon source in the tank body 1, thereby improving the reaction efficiency of water and carbon source at the corner and improving the reaction efficiency of the anaerobic tank.

[0027] Finally, it should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
