[0001] The utility model relates to the technical field of biogas tanks, in particular to a conveying structure of a biogas tank. Background Art

[0002] A biogas digester is a device that uses organic waste to produce combustible gas methane through anaerobic fermentation.

[0003] During the feedstock transportation process in biogas digesters, as digesters are often deep, a specialized delivery system is required to deliver the feedstock into the digester. However, due to the varying characteristics of the feedstock, blockages may occur in the pipeline during delivery. Furthermore, since the input pipeline is fixed, the input feedstock may accumulate in specific areas, affecting not only the uniform distribution of the feedstock but also the normal fermentation process of the biogas, thereby reducing the biogas yield and efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art that due to the different characteristics of the raw materials, blockage may occur in the pipeline during transportation, and since the input pipeline is fixedly installed, the input raw materials may accumulate in a specific area, which not only affects the uniform distribution of the raw materials, but also may interfere with the normal fermentation process of biogas, thereby reducing the yield and efficiency of biogas.

The swing of the export plate causes the entry trajectory of the material to change continuously, so that the material is more evenly distributed in the biogas tank, preventing the raw materials from accumulating in one place, making the biogas fermentation more uniform, and improving the biogas fermentation efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] See also Figure 1-5The utility model provides a technical solution: a conveying structure of a biogas tank, including soil 5, in which a raw material pool 1, a first transmission pipe 2, a second transmission pipe 3 and a third transmission pipe 4 are fixedly embedded, the output end of the raw material pool 1 is fixedly connected to the first transmission pipe 2, the output end of the first transmission pipe 2 is fixedly connected to the second transmission pipe 3, the output end of the third transmission pipe 4 faces the biogas tank, and both sides of the output end of the third transmission pipe 4 are fixedly connected to a connecting frame 12, the two connecting frames 12 are rotatably connected to an export plate 11, one end of the export plate 11 is fixedly connected to a gear 13, the side end of the third transmission pipe 4 is fixedly connected to a mounting frame 21, and the third transmission pipe 4 is rotatably connected to a rotating shaft 21. Shaft 7, a force-bearing structure is provided on the periphery of the rotating shaft 7, one end of the rotating shaft 7 passes through the third transmission pipe 4 to the inside of the mounting frame 21, and a rotating disk 19 is fixedly connected to the end of the rotating shaft 7. A transmission structure is provided between the rotating disk 19 and the gear 13, and the rotating disk 19 is connected to the gear 13 for transmission. The gear 13 cooperates with the transmission structure to realize the reciprocating swing of the export plate 11 when the raw material flows, so that the material passes through the export plate 11 into the biogas tank. The swing of the export plate 11 causes the entry trajectory of the material to change continuously, so that the material is more evenly distributed in the biogas tank, preventing the raw material from piling up in one place, making the biogas fermentation more uniform, and improving the biogas fermentation efficiency.

[0025] like Figure 1-5 As shown, the transmission structure includes a rack 14 slidably connected to the inside of the mounting frame 21, the rack 14 is meshed with the gear 13 for transmission connection, the outer end of the end face of the rotating disk 19 is fixedly connected to the connecting shaft 20, and the outer periphery of the connecting shaft 20 is rotatably connected to the connecting rod 16. The connecting rod 16 is in transmission connection with the rack 14 and can transmit the rotation of the rotating shaft 7 to the gear 13, and make the gear 13 rotate back and forth.

[0026] like Figure 1-5 As shown, the connecting plates 8 are evenly distributed along the axis of the rotating shaft 7, and the rotating shaft 7 can be driven to rotate by the connecting plates 8 in conjunction with the impact of the flowing material.

[0027] like Figure 1-5 As shown, the rack 14 is fixedly connected to a mounting block 17 at one end away from the gear 13, and a sliding shaft 18 is fixedly connected inside the mounting block 17. The sliding shaft 18 is rotatably connected to the sliding shaft 18 at one end of the connecting rod 16 away from the connecting shaft 20, and the sliding shaft 18 cooperates with the mounting block 17 to rotate the other end of the connecting rod 16.

[0028] like Figure 1-5 As shown, mounting blocks 17 are provided on the inner walls at both ends of the mounting frame 21, and both ends of the sliding shaft 18 are slidably connected to the inside of the corresponding guide grooves 15 on both sides. Through the cooperation between the guide grooves 15 and the sliding shaft 18, the sliding of the rack 14 is guided.

[0029] like Figure 1-5As shown, the raw material pool 1, the first transmission pipe 2, the second transmission pipe 3 and the third transmission pipe 4 are all inclined. The inclined first transmission pipe 2, the second transmission pipe 3 and the third transmission pipe 4 allow the material to be affected by gravity, making the material flow smoother.

[0030] like Figure 1-5 As shown, there is a height difference between the first transmission pipe 2 and the second transmission pipe 3, and the connection between the first transmission pipe 2 and the second transmission pipe 3 is vertical, so that the height difference between the first transmission pipe 2 and the second transmission pipe 3 can increase the sliding impact force of the material in the pipeline, making the impact of the material on the connecting plate 8 more stable.

[0031] like Figure 1-5 As shown, the edges of the connection between the first transmission tube 2 and the second transmission tube 3 are circularly treated, and a plurality of evenly distributed separation teeth 6 are fixedly connected to both sides of the circular arc. The edges of the connection between the first transmission tube 2 and the second transmission tube 3 are circularly treated to prevent the raw materials from rushing out and getting stuck at the connection between the first transmission tube 2 and the second transmission tube 3. The separation teeth 6 can be used to separate the adhering materials.

[0032] Working Principle: During the material conveying process, the material first passes through the material pool 1 and enters the first transfer pipe 2. Due to the height difference between the first and second transfer pipes 2, 3, this height difference enhances the flow impact of the material as it flows from the first transfer pipe 2 to the second transfer pipe 3. Once the material enters the third transfer pipe 4 through the second transfer pipe 3, the impact force of the material interacts with the connecting plate 8, causing the rotating shaft 7 to rotate. The material then enters the biogas tank through the outlet plate 11. As the rotating shaft 7 rotates, it also drives the rotating disk 19. The rotation of the rotating disk 19, in conjunction with the connecting shaft 20, further drives the connecting rod 16 to rotate eccentrically. As the connecting rod 16 rotates, the position of its other end also changes. This end, through the cooperation of the mounting block 17 and the sliding shaft 18, drives the rack 14 to move. Since both ends of the sliding shaft 18 are guided and limited by the guide groove 15, the rotating disk 19 can drive the rack 14 to reciprocate along the guide groove 15 when it rotates. The rack 14 can engage with the gear 13 during the movement, so that the export plate 11 rotates, thereby changing the angle of the export plate 11. Through the swing of the export plate 11, the entry trajectory of the material changes continuously, which can make the distribution of the material in the biogas tank more uniform, effectively prevent the raw materials from piling up in one place, thereby making the biogas fermentation more uniform and improving the efficiency of biogas fermentation.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
