Description

Technical Field

[0001] This utility model relates to the field of biogas fermentation tank technology, specifically a propulsion-type manure biogas mixing device. Background Technology

[0002] Biogas fermentation, also known as anaerobic digestion or anaerobic fermentation, refers to the process by which organic matter (such as human and livestock manure, straw, weeds, etc.) is decomposed and metabolized by various microorganisms under specific moisture, temperature, and anaerobic conditions, ultimately forming a combustible mixture of gases such as methane and carbon dioxide. Biogas fermentation systems are based on the principles of biogas fermentation, aiming at energy production and ultimately achieving the comprehensive utilization of biogas, biogas slurry, and biogas residue.

[0003] A search revealed that utility model patent CN218910334U discloses a "multi-stage transverse propulsion biogas fermentation tank". This multi-stage transverse propulsion biogas fermentation tank, through the setting of a propulsion mechanism, has a first motor driving a lead screw to rotate. When the threaded block moves to the right along the lead screw, the first toothed plate drives the meshing rear gear to rotate clockwise, and the second toothed plate drives the meshing front gear to rotate counterclockwise, thereby driving the symmetrically arranged third toothed plate to move to the left at the same time. This achieves the effect of the first and second push plates pushing each other in the inner cavity of the fermentation tank, realizing multi-stage transverse propulsion, thereby pushing and stirring the material, avoiding the accumulation of material at the bottom, and improving the fermentation speed.

[0004] The device's agitation mechanism is located at the bottom of the fermentation tank. Solid matter inside the fermentation tank can easily clog the agitation mechanism at the bottom, causing it to jam and malfunction. Utility Model Content

The first rotating rod 24 is rotatably connected between the two sets of corresponding upright plates 23. The push plate 25 is fixedly connected to the bottom of the sliders 22. The bottom of the push plate 25 has a bottom groove 251, and multiple sets of bottom grooves 251 are provided. The bottom grooves 251 facilitate the movement of the push plate 25.

[0023] The propulsion mechanism 2 also includes a motor 26, a lead screw 27, and a connecting plate 28. The motor 26 is fixedly connected to the upper end of the fermentation tank 1, the lead screw 27 is fixedly connected to the output end of the motor 26, and the connecting plate 28 is threadedly connected to the circumferential side of the lead screw 27. The upper end of the connecting plate 28 is provided with a threaded groove that matches the lead screw 27.

[0024] The propulsion mechanism 2 also includes a second rotating rod 29 and a connecting rod 210. There are two sets of second rotating rods 29, which are rotatably connected to the left and right sides of the connecting plate 28 respectively. There are two sets of connecting rods 210, which are fixedly connected to the corresponding second rotating rod 29 and the first rotating rod 24.

[0025] A feed pipe 3 is fixedly connected to the side of the fermentation tank 1. A solenoid valve 4 is installed at the upper end of the feed pipe 3. The solenoid valve 4 can be used to control the feeding of materials into the fermentation tank 1, and at the same time prevent the gas inside the fermentation tank 1 from being discharged from the feed pipe 3.

[0026] The fermentation tank 1 is equipped with an exhaust mechanism 5 at the upper end. The exhaust mechanism 5 includes a shell 51 that is fixedly connected to the upper end of the fermentation tank 1.

[0027] An air inlet 52 is provided at the bottom of the outer shell 51, and a variable diameter groove 53 is provided inside the outer shell 51. The variable diameter groove 53 is connected to the air inlet 52. A hole matching the air inlet 52 is provided at the upper end of the fermentation tank 1.

[0028] The outer casing 51 has a sliding groove 54 inside and an air outlet 55 at the upper end. The sliding groove 54 is connected to the variable diameter groove 53 and the air outlet 55.

[0029] The exhaust mechanism 5 also includes a limiting plate 56 slidably connected inside the slide groove 54, a sealing plug 57 fixedly connected to the bottom of the limiting plate 56, and a spring 58 fixedly connected to the upper end of the limiting plate 56.

[0030] It should be noted that the motor 26 is controlled by a controller, which can control the motor 26 to drive the lead screw 27 to rotate in the forward and reverse directions.

[0031] In summary, the propulsion-type manure biogas mixing device provided by this utility model, when in operation, is driven by the motor 26 to rotate the lead screw 27. The rotation of the lead screw 27 can cause the connecting plate 28 to move along the lead screw 27. At this time, the second rotating rod 29 moves synchronously with the connecting plate 28. The movement of the second rotating rod 29 can change the angle between the connecting rod 210 and the guide rod 21. At this time, the slider 22 slides along the guide rod 21. The movement of the slider 22 can drive the push plate 25 to propel and mix the manure inside the fermentation tank 1.

[0032] By opening the solenoid valve 4, the manure can enter the fermentation tank 1 through the feed pipe 3. When the pressure inside the fermentation tank 1 is too high, the gas inside the fermentation tank 1 will push the sealing plug 57 upward. At this time, the gas can pass through the air inlet 52, the variable diameter groove 53 and the slide 54, and finally be discharged from the air outlet 55. When the pressure inside the fermentation tank 1 is normal, the spring force of the spring 58 can make the limiting plate 56 and the sealing plug 57 return to the downward. The internal pressure of the fermentation tank 1 can be adjusted through this structure.
