Technical Field
[0001] This utility model relates to the field of biogas digesters, specifically a biogas digester for fermenting livestock and poultry manure. Background Technology
[0002] In existing technologies, biogas digesters mainly consist of a digester body, a gas collection hood, an exhaust pipe, a feed pipe, and a discharge channel. During use, the manure produced by livestock is sent into the interior of the digester body through the feed pipe. Microbial fermentation is carried out inside the digester body, and the decomposition of organic matter produces biogas that floats up into the interior of the gas collection hood. The gas pipeline is connected to the exhaust pipe, and the discharge channel is used to retrieve the biogas residue from the lower layer.
[0003] However, during use, due to the large diameter of the biogas digester, it is difficult to retrieve the biogas residue in the middle and areas far from the discharge channel, making it inconvenient for staff to use. Therefore, a biogas digester for the fermentation of manure in livestock and poultry farms is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a biogas digester for the fermentation of manure in livestock and poultry farms.

[0006] Preferably, a bracket is fixed to the top of the discharge channel, a slurry pump is installed on the bracket, a suction pipe is installed on the slurry pump, and the suction pipe is inserted into the interior of the discharge channel.
[0007] Preferably, a filter grid is fixedly connected to the bottom of the discharge channel. The filter grid is arranged in a cylindrical structure, and the bottom end of the suction pipe is inserted into the interior of the filter grid and fixedly connected thereto.
[0008] Preferably, a cleaning plate is slidably connected inside the discharge channel, a pull rope is fixedly connected to the cleaning plate, a through hole is opened on the cleaning plate, the filter grid is located in the middle of the through hole, a plurality of drainage holes are opened on the cleaning plate, a reel is rotatably connected to the top of the discharge channel, and the top end of the pull rope is fixedly connected to the reel.

[0010] Preferably, the rotating shaft is located at the center of the pool, the guide pusher is arranged in an arc shape, and the connecting chute is inclined.
[0011] The advantages of this utility model are: 1. This utility model, by setting up a motor, a rotating shaft, a disc body, and a guide push plate, allows workers to start the motor when cleaning biogas residue.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0016] Specific implementation examples are given below.
[0017] Please see Figure 1-5 As shown, a biogas digester for livestock and poultry farm manure fermentation includes a tank body 11. A gas collection hood 12 is fixedly connected to the top of the tank body 11, and an exhaust pipe 13 is fixedly connected to the gas collection hood 12. An inlet pipe 14 and a connecting chute 16 are installed on the tank body 11, and a discharge channel 15 is fixedly connected to the end of the connecting chute 16. A motor 17 is fixedly connected to the top of the gas collection hood 12, and a rotating shaft 18 is fixedly connected to the output end of the motor 17. A disc is fixedly connected to the bottom end of the rotating shaft 18, and multiple guide push plates 19 are fixedly connected to the disc. When cleaning the biogas residue, the staff starts the motor 17, which drives the rotating shaft 18 to rotate slowly. This causes the bottom plate and the guide plate 19 to rotate. The rotation of the guide plate 19 pushes the lower layer of biogas residue, thus pushing the biogas residue towards the connecting chute 16 at the edge of the pool body 11. This makes it convenient for the staff to clean the biogas residue at the bottom of the biogas digester and makes it easy to use.
[0018] Furthermore, such as Figure 1-5 As shown, a bracket 21 is fixed to the top of the discharge channel 15, a slurry pump 22 is installed on the bracket 21, a suction pipe 23 is installed on the slurry pump 22, and the suction pipe 23 is inserted into the interior of the discharge channel 15. In use, a slurry pump 22 is installed on the top of the discharge channel 15 via a bracket 21. The slurry pump 22 sucks up the biogas residue at the bottom of the discharge channel 15 through a suction pipe 23, which makes it convenient for staff to clean the biogas residue and facilitates use.
[0019] Furthermore, such as Figure 1-5As shown, a filter grid 3 is fixedly connected to the bottom of the discharge channel 15. The filter grid 3 has a cylindrical structure. The bottom end of the suction pipe 23 is inserted into the filter grid 3 and fixedly connected to it. A cleaning plate 41 is slidably connected inside the discharge channel 15. A pull rope 43 is fixedly connected to the cleaning plate 41. The cleaning plate 41 has a through hole. The filter grid 3 is located in the middle of the through hole. The cleaning plate 41 has multiple drainage holes 42. A reel 44 is rotatably connected to the top of the discharge channel 15. The top end of the pull rope 43 is fixedly connected to the reel 44. Multiple stirring blades 5 are fixedly connected to the surface of the rotating shaft 18. The multiple stirring blades 5 are located inside the tank body 11. When cleaning the breeding room, manure, plant fibers, and foreign objects on the ground will enter the biogas digester through the corresponding pipes. Some plant fibers and foreign objects that are not decomposed by microorganisms can easily damage the slurry pump 22. Therefore, a filter grid 3 is installed at the bottom of the discharge channel 15 to filter and intercept them, thereby reducing the possibility of the slurry pump 22 being blocked. A cleaning plate 41 is slidably connected inside the discharge channel 15. A pull rope 43 is installed on the cleaning plate 41. Pulling the rope 43 can lift the cleaning plate 41, thereby lifting the foreign objects and plant fibers deposited in the discharge channel 15, making it easier for staff to clean. A reel 44 is rotatably connected to the top of the pull rope 43. The pull rope 43 is wound up by rotating the reel 44, which is convenient to use. An agitator 5 is installed on the rotating shaft 18. The motor 17 is started periodically to agitate the biogas slurry and biogas residue, which facilitates fermentation.
[0020] Furthermore, such as Figure 1-5 As shown, the rotating shaft 18 is located at the center of the pool body 11, the guide push plate 19 is arranged in an arc shape, and the connecting chute 16 is arranged at an angle. When in use, the connecting chute 16 is set at an angle, which makes it easy for the biogas residue to enter the interior of the discharge channel 15, making it convenient for staff to extract the biogas residue from the biogas digester.
[0021] Furthermore, such as Figure 1-5 As shown, a crank handle 7 is fixedly connected to the side of the reel 44. When in use, the crank handle 7 makes it convenient for workers to reel in the rope 43, thereby facilitating the lifting of the cleaning plate 41 and making it easy to use.
[0022] Working principle: When cleaning biogas residue, the operator starts the motor 17, which drives the rotating shaft 18 to rotate slowly. This, in turn, drives the bottom plate and the guide plate 19 to rotate. The rotation of the guide plate 19 pushes the lower layer of biogas residue, thus pushing the biogas residue towards the connecting chute 16 at the edge of the tank 11. This makes it convenient for the operator to clean the biogas residue at the bottom of the biogas digester, making it easy to use. During use, a slurry pump 22 is installed on the top of the discharge channel 15 via a bracket 21. The slurry pump 22 sucks up the biogas residue at the bottom of the discharge channel 15 through the suction pipe 23, making it convenient for the operator to clean the biogas residue, making it easy to use. When cleaning the breeding room, feces, plant fibers, and foreign objects on the ground will enter the biogas digester through the corresponding pipes. Some plant fibers and foreign objects that are not decomposed by microorganisms can easily damage the slurry pump 22. Therefore, a filter grid 3 is installed at the bottom of the discharge channel 15 to filter and intercept them, thereby reducing the possibility of the slurry pump 22 becoming clogged. A cleaning plate 41 is slidably connected inside the discharge channel 15, and a pull rope 43 is installed on the cleaning plate 41. The cleaning plate 41 is raised by pulling the rope 43. This allows for the removal of foreign objects and plant fibers deposited in the discharge channel 15, facilitating cleaning by staff. The top of the pull rope 43 is rotatably connected to a reel 44, which is rotated to wind up the pull rope 43 for easy use. An agitator 5 is installed on the rotating shaft 18, and the motor 17 is started periodically to agitate the biogas slurry and biogas residue for easy fermentation. During use, the connecting chute 16 is inclined, which facilitates the entry of biogas residue into the discharge channel 15, making it convenient for staff to extract the biogas residue from the biogas digester.
