A residue conveying mechanism for a biogas digester fermentation device Technical Field

[0001] This utility model relates to the technical field of biogas digester fermentation devices, and in particular to a residue conveying mechanism for biogas digester fermentation devices. Background Technology

[0002] A biogas fermentation unit is a device that converts organic matter into biogas through the metabolic action of microorganisms under anaerobic conditions. Its core structure includes a fermentation tank, a gas storage chamber, inlet and outlet ports, and a stirring device, designed to provide a closed environment to promote microbial activity and achieve efficient gas production.

[0003] The residual material discharge structure is designed to periodically remove sediment (such as biogas residue) generated during fermentation. This maintains the effective volume of the fermenter, ensuring sufficient contact between microorganisms and fresh raw materials; prevents sediment from clogging the discharge port, ensuring smooth fermentation; and the discharged residual material is rich in nutrients and can be used as fertilizer or soil conditioner, achieving resource recycling.

[0004] In existing technologies, the residue from the fermentation tank is usually filtered by an auger. Although this can meet most usage requirements, it can easily cause blockage when the residue is viscous, contains long fiber impurities (such as straw, plastic bags), or foreign objects.

[0005] Therefore, it is necessary to provide a residue conveying mechanism for biogas digester fermentation devices to solve the above-mentioned technical problems. Summary of the Invention

One end of the drive shaft is connected to the drive component, and the other end extends to the outside and is connected to the crushing chamber. The discharge auger is also equipped with a discharge mechanism.

[0011] Preferably, two grinding wheels for crushing residue are rotatably connected inside the grinding chamber. The two grinding wheels consist of multiple blades and a transmission rod. One end of the transmission rod is rotatably connected to the grinding chamber, and the other end extends through to the outside of the grinding chamber and is fixedly connected to a connecting gear. The two connecting gears mesh with each other.

[0012] Preferably, one end of the transmission rod passes through the connecting gear and is provided with a linkage wheel for linkage.

[0014] Preferably, the connecting sleeve is further provided with a connecting bearing to facilitate the rotation of the drive shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model, by setting up a crushing chamber and connecting it with a drive shaft, enables the crushing chamber to provide power output for crushing residual materials during the material discharge process. This effectively ensures that residual materials are crushed during use, thus avoiding blockage of the discharge auger caused by foreign objects or long straw inside.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0023] First embodiment:

[0024] As shown in Figures 1-3, this utility model provides a residue conveying mechanism for a biogas digester fermentation device, including a mounting base 1. The mounting base 1 is provided with a discharge auger 11 for discharging residue. The bottom of the discharge auger 11 is provided with multiple support seats 12 for support. One end of the discharge auger 11 is connected to a transmission component 13 for providing power, and the other end is connected to a discharge assembly 2 for processing residue. The discharge assembly 2 includes a crushing chamber 21 for processing residue and a 22 for connecting to the discharge auger 11. The discharge auger 11 is provided with a drive shaft 111, and the drive shaft 111 is provided with auger blades 112. One end of the drive shaft 111 is connected to the transmission component 13, and the other end extends to the outside of the 22 and is connected to the crushing chamber 21. The discharge auger 11 is also provided with a discharge 113. In actual use, when the staff needs to discharge the biogas digester fermentation device, the crushing chamber 21 can be connected to its discharge end, and the residue can be discharged into the crushing chamber 21. Under the action of the crushing chamber 21, the residue can be effectively crushed. The crushed residue will fall into 22. At this time, under the rotation of the drive shaft 111, the auger blade 112 can be effectively driven to rotate. During the rotation of the auger blade 112, the residue can be moved to 113 to achieve the effect of discharging the residue.

[0025] The technical effects of the above technical solution are as follows: by setting up a crushing chamber 21 and connecting the drive shaft 111 to it, the crushing chamber 21 can be powered to crush the residual material during the discharge process. This effectively ensures that the residual material can be crushed during use, thus avoiding the blockage of the discharge auger 11 caused by foreign objects or long straw inside.

[0026] In a preferred embodiment, two crushing wheels 213 for crushing residue are rotatably connected inside the crushing chamber 21. Each crushing wheel 213 consists of multiple blades and a transmission rod 211. One end of the transmission rod 211 is rotatably connected to the crushing chamber 21, and the other end extends to the outside of the crushing chamber 21 and is fixedly connected to a connecting gear 212. Both connecting gears 212 mesh with each other. In actual use, when the operator controls the transmission shaft 111 to drive one of the connecting gears 212 to rotate, the two meshing connecting gears 212 can drive the crushing wheel 213 to rotate in opposite directions. This allows the crushing wheel to effectively shred long fiber or agglomerated foreign objects in the residue, preventing blockage of the discharge auger 11.

[0027] In a preferred embodiment, a connecting gear 212 is provided with a linkage wheel 214 for linkage. A connecting sleeve 221 for mounting a drive shaft 111 is provided on 22. A drive shaft 111 is also provided with a drive wheel 223 for transmission, and a drive belt 224 for transmission is provided on the drive wheel 223. The drive belt 224 is connected to the linkage wheel 214. This connection method allows the drive shaft 111 to rotate by controlling the transmission component 13 during operation, thus achieving the effect of transmission and driving the connecting gear 212. Furthermore, the residue crushed in the crushing chamber 21 falls into 22 under gravity and is conveyed through the drive shaft 111 and the auger blade 112 within 22.

[0028] The technical effects of the above embodiments are as follows: by setting the connecting sleeve 221 and the transmission wheel 223, the transmission shaft 111 can be effectively installed during use and the transmission shaft 111 can have a good transmission effect. It satisfies the requirement that only one transmission component is set to realize the effect of conveying raw materials and driving the crushing chamber 21 to crush raw materials, making it more energy-efficient and more efficient.

[0029] As a preferred technical solution in this embodiment, a connecting bearing 222 is also provided inside the connecting sleeve 221 to facilitate the rotation of the drive shaft 111. By providing the connecting bearing 222, the drive shaft 111 can be effectively rotated during use, thereby ensuring the stability of the drive shaft 111 during use.

[0030] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
