Description

Technical Field

[0001] This utility model relates to the field of livestock manure fermentation technology, specifically to a fermentation device for the harmless treatment of livestock and poultry manure. Background Technology

[0002] Fermentation devices for the harmless treatment of livestock and poultry manure are environmentally friendly equipment that transforms manure into organic fertilizer or energy substances through microbial fermentation, while simultaneously sterilizing, deodorizing, and degrading harmful substances. Its core principle is to utilize high-temperature aerobic fermentation or anaerobic digestion to decompose the organic matter in the manure into stable humus or biogas, while killing pathogens, parasite eggs, and other harmful components. It is a key facility for the resource utilization of livestock and poultry breeding waste.

[0003] Existing technology publication CN219730744U discloses a livestock and poultry manure fermentation and harmless treatment device, belonging to the field of fermentation technology. This livestock and poultry manure fermentation and harmless treatment device includes a fermentation structure and a gas storage structure. The fermentation structure includes a fermentation chamber one, a feeding component, and a flushing component. The flushing component is fixed to the top of the fermentation chamber one. The feeding component includes an electric telescopic rod, which is fixed inside the fermentation chamber one. A cover plate is fixed to the end of the electric telescopic rod, a sealing gasket is fixed to the bottom of the cover plate, a connecting rod is fixed to the bottom of the cover plate, and a sealing block is fixed to the end of the connecting rod. This utility model, by setting two sealing structures inside the fermentation chamber one, separates the space for pouring manure from the fermentation space, thereby preventing the continuous emission of odors. Using an air pump, biogas from fermentation chamber one and fermentation chamber two can be drawn into a gas storage tank, thereby increasing the concentration of biogas.

[0004] While existing fermentation devices for the harmless treatment of livestock and poultry manure can achieve the fermentation function, they have significant shortcomings in practical applications: when treating livestock and poultry manure with high moisture content, the fermented products still contain too much water, making them unusable directly upon discharge; subsequent treatment with dewatering or drying equipment is required, which not only increases the processing steps and costs but also reduces the overall practicality of the fermentation device. Therefore, we propose a fermentation device for the harmless treatment of livestock and poultry manure. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a fermentation device for harmless treatment of livestock and poultry manure, including a fermentation body 1. The top of the fermentation body 1 is bolted with an exhaust pipe 2, a feeding hopper 4, and an air supply pipe 7. A heating box 8 is installed on the outside of the air supply pipe 7. A blower 9 is bolted to one end of the air supply pipe 7. A discharge pipe 12 is welded to the center of the bottom of the fermentation body 1. A mounting bracket 13 is bolted to the outside of one end of the discharge pipe 12. An adjusting shaft 14 is threaded through one side of the mounting bracket 13. An adjusting disc 16 is threaded to the outside of the adjusting shaft 14. A sealing plate 15 is slidably connected to one end of the adjusting shaft 14. A compression spring 17 is installed between the sealing plate 15 and the adjusting disc 16. A drainage hopper 21 is welded to the bottom of the discharge pipe 12. A filter screen 22 is installed on the inside of the drainage hopper 21.

[0024] Furthermore, a stirring motor 10 is installed on the front of the fermentation body 1. The driving end of the stirring motor 10 is fixed with a stirring shaft 1001 through a coupling. A stirring rod 1002 is welded to the outside of the stirring shaft 1001. By starting the stirring motor 10, the stirring motor 10 drives the stirring rod 1002 to rotate through the stirring shaft 1001, thereby stirring the feces.

[0025] Furthermore, a filter sleeve 3 is threadedly connected to the outer side of the exhaust pipe 2, and a filter element 301 is installed inside the filter sleeve 3. The gas can be filtered through the filter element 301, so that the gas produced during the fermentation process can be discharged in a harmless manner.

[0026] Furthermore, a baffle 5 is slidably connected to one side of the feed hopper 4, and a handle 6 is integrally formed on one side of the baffle 5. The handle 6 can be used to push and pull the baffle 5, thereby facilitating the opening and closing of the feed hopper 4 by the staff.

[0027] Furthermore, a conveyor motor 18 is installed at the other end of the discharge pipe 12. The drive end of the conveyor motor 18 is fixed to a conveyor shaft 19 via a coupling. A spiral blade 20 is welded to the outside of the conveyor shaft 19. By starting the conveyor motor 18, the conveyor motor 18 drives the spiral blade 20 to rotate via the conveyor shaft 19, thereby conveying the feces.

[0028] Furthermore, a support frame 11 is welded to the bottom of the fermentation body 1. There are four support frames 11, which are located at the four corners of the bottom of the fermentation body 1. The support frames 11 make the fermentation device more stable and less prone to shaking.

[0029] Working Principle: After installation, first check the installation, fixation, and safety precautions of this utility model. When using the fermentation device for harmless treatment of livestock and poultry manure, the operator opens the baffle 5 and feeds the manure into the fermentation body 1 through the feed hopper 4. After adding the manure, close the baffle 5 and start the stirring motor 10. The stirring motor 10 drives the stirring rod 1002 to rotate through the stirring shaft 1001, thereby stirring the manure. During the stirring process, if the manure fermentation temperature is insufficient, heat is generated by starting the heating box 8, and then the blower 9 is started. The blower 9 generates airflow, which passes through the air supply pipe 7 and the heating box 8 to form hot air. The hot air enters the fermentation body 1, allowing the manure inside the fermentation body 1 to reach the fermentation temperature. When waste gas is generated during fermentation, the waste gas is discharged through the exhaust pipe 2. During the discharge process, the waste gas passes through the filter sleeve 3, and the filter element 301 inside the filter sleeve 3... The system can filter exhaust gas to achieve harmless emission. When the manure has fermented and needs to be discharged, and the manure has too much moisture, the staff can start the conveyor motor 18. The conveyor motor 18 drives the spiral blade 20 through the conveyor shaft 19 to transport the manure. When the manure is transported to the sealing plate 15, it will be blocked by the sealing plate 15 and squeeze the sealing plate 15. At this time, the water in the manure can be squeezed out. When the squeezing pressure reaches a certain level, the sealing plate 15 slides through the adjusting shaft 14, and squeezes the compression spring 17, opening the discharge port. At this time, the manure can be discharged. The excess water is filtered through the water filter screen 22 and discharged from the drain hopper 21. When the manure is relatively dry after fermentation, the staff can open the sealing plate 15 to allow the manure to be discharged quickly. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
