Description

Technical Field

[0001] The utility model relates to the technical field of biogas slurry resource processing, in particular to a straw biogas slurry rapid mixing device. Background Art

[0002] Biogas slurry is the upper layer of liquid left after various organic materials, such as human and animal feces, crop straw, and grass, undergo anaerobic fermentation in a biogas tank to produce biogas. It contains a comprehensive range of nutrients and is rich in organic matter. Because biogas slurry is high in water content, making it difficult to transport and use, the current solution is to produce biogas slurry-straw fertilizer. This fertilizer leverages the high moisture content, high volume, and high nutrient content of biogas slurry, while the dryness and low nutrient content of agricultural straw. Biogas slurry and straw are mixed and fermented. After the fermentation is complete, the straw-biogas slurry is filtered and mixed before being processed into fertilizer.

[0003] Publication number CN112742247B describes a straw-liquid mixing device for environmentally friendly biogas projects. The device comprises a base, symmetrically arranged brackets on top of the base, a mixing box, a mixing box positioned between the two brackets, a rotating shaft, a rotating shaft rotatably mounted at the center of the mixing box, stirring blades, a stirring blade positioned below the rotating shaft, and a liquid inlet pipe. A driving mechanism drives the rotating shaft and stirring blades to rotate, thereby mixing the straw-liquid. This is achieved by a pushing mechanism, causing the lower layer of straw-liquid to roll upward.

[0004] Although the device can drive the rotation mechanism to drive the rotation shaft and the stirring blades through the driving mechanism, and thus the mixing of the straw and biogas can be achieved through the pushing mechanism, so that the lower layer of straw and biogas rolls upward, but due to the small weight of the straw, the straw will float on the surface of the biogas liquid, making the device mixing the straw and biogas incomplete and uneven. In addition, during the process of mixing the biogas, the odor of the biogas liquid is emitted, resulting in an unpleasant smell in the air near the device, making the working environment of the staff poor. In view of this, we propose a straw and biogas rapid mixing device. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-4 , the utility model provides a technical solution:

[0028] A straw-biogas rapid mixing device comprises a base 1, a mixing tank 11 is fixedly connected to the center of the top of the base 1 by bolts, and support frames 12 are symmetrically welded and fixed near the left and right sides of the top of the base 1 to play a supporting role.

[0029] Furthermore, a fan 13 is fixedly connected to the outer surface of the support frame 12 by bolts, and the air inlet of the fan 13 is connected to an air intake pipe 14. One end of the air intake pipe 14 passes through the top of the support frame 12 corresponding to its position, and is used to inhale the air between the two support frames 12.

[0030] It should be added that the air outlet of the fan 13 is connected to an air outlet pipe 15, and a number of activated carbon filter plates 16 are fixed to the inner wall of the air outlet pipe 15 by glue. The activated carbon filter plates 16 are evenly spaced and are used to filter the air and remove air odor.

[0031] As a preference of this embodiment, a driving mechanism 2 is provided above the base 1. The driving mechanism 2 includes two driving motors 21. The two driving motors 21 are fixedly connected to the inner surfaces of the two support frames 12 by bolts respectively to drive the cam 22 to rotate.

[0032] Specifically, the output shaft of the driving motor 21 is coaxially connected to the cam 22 to drive the moving frame 23 to move. The moving frame 23 is provided between the two supporting frames 12. The top of the moving frame 23 is in contact with the bottom of the cam 22 to drive the two mixing motors 31 to move.

[0033] Specifically, the top of the base 1 near the left and right sides are symmetrically fixed with sliding rods 24 by bolts to limit the moving direction of the sliding ring 26. The top of the sliding rod 24 is welded and fixed with a limiting plate 25.

[0034] Specifically, a sliding ring 26 is slidably connected to the circumferential outer wall of the sliding rod 24 to limit the moving direction of the connecting rod 27 .

[0035] Specifically, connecting rods 27 are symmetrically welded and fixed at the top of the sliding ring 26 near the left and right sides. The top of the connecting rod 27 is fixedly connected to the bottom of the movable frame 23 by bolts to drive the sliding ring 26 to move and limit the moving direction of the movable frame 23.

[0036] It should be supplemented that a spring 28 is provided on the circumferential outer wall of the slide rod 24 , and the top end of the spring 28 is fixedly connected to the bottom end of the slide ring 26 corresponding to its position, so as to limit the position of the slide ring 26 .

[0037] Furthermore, a mixing mechanism 3 is symmetrically provided near the left and right sides of the top of the movable frame 23. The mixing mechanism 3 includes a mixing motor 31. The mixing motor 31 is fixedly connected to the top of the movable frame 23 by bolts to drive the mounting rod 32 to rotate.

[0038] Specifically, the output shaft of the mixing motor 31 is coaxially connected to the mounting rod 32 , and the bottom end of the mounting rod 32 passes through the bottom of the moving frame 23 to drive the stirring rod 33 to rotate.

[0039] Specifically, a plurality of stirring rods 33 are fixedly connected to the circumferential outer wall of the mounting rod 32 by means of bolts. The stirring rods 33 are evenly arranged at equal intervals and are used to stir the straw and the biogas slurry.

[0040] It is worth mentioning that the structures and working principles of the fan 13 and the activated carbon filter plate 16 involved in this embodiment are well known to those skilled in the art and will not be elaborated here.

[0041] During specific use, the user first pours straw and biogas slurry into the mixing tank 11, turns on the two mixing motors 31, and the two mixing motors 31 respectively drive the two mounting rods 32 to rotate, thereby driving all the stirring rods 33 to rotate and stir the straw and biogas slurry;

[0042] Then, the two drive motors 21 are turned on. The two drive motors 21 respectively drive the two cams 22 to rotate, causing the protruding ends of the two cams 22 to rotate downward, thereby driving the movable frame 23 to move downward, thereby driving the four connecting rods 27 to move downward, thereby driving the two sliding rings 26 to move downward, thereby compressing the two springs 28 respectively.

[0043] Until the protruding ends of the two cams 22 rotate to the lowest position, the protruding ends of the two cams 22 begin to rotate upward, and the two springs 28 begin to restore their initial lengths, thereby driving the two sliding rings 26 to move upward, thereby driving the four connecting rods 27 to move upward, and thereby driving the moving frame 23 to move upward;

[0044] Until the protruding ends of the two cams 22 rotate to the highest position again, the protruding ends of the two cams 22 begin to rotate downward, thereby driving the movable frame 23 to move downward again;

[0045] During the rotation of the two cams 22, the movable frame 23 performs up-and-down reciprocating motion, thereby driving the two mixing motors 31 to perform up-and-down reciprocating motion, thereby driving the two mounting rods 32 to perform up-and-down reciprocating motion during the rotation, thereby driving all the stirring rods 33 to perform up-and-down reciprocating motion during the rotation;

[0046] When the stirring rod 33 near the top moves to the highest position, the stirring rod 33 drives the straw floating on the surface of the biogas slurry to move downward until the straw and the biogas slurry are evenly mixed, and then the two driving motors 21 and the two mixing motors 31 are turned off;

[0047] When the working environment needs to be improved, the user first turns on the two fans 13. The two fans 13 respectively suck the air between the two support frames 12 through the two air inlet pipes 14 and blow the air out through the air outlet pipes 15. In the process of the air passing through the air outlet pipes 15, the activated carbon filter plate 16 in the air outlet pipes 15 removes odors in the air.
