[0002] For example, the Chinese patent publication number CN214457669U discloses a fermentation device for rapid decomposition of livestock and poultry manure. The livestock and poultry manure in the fermentation barrel is heated by a heating pipe, and the motor drives the reduction gear box to rotate the rotating shaft, which drives the fermentation barrel to rotate. The fermentation barrel causes the livestock and poultry manure in the fermentation barrel to roll in the fermentation barrel, so that it is evenly heated and fermented. By setting up this equipment, the livestock and poultry manure can be kept in a moving state during the heating process, so that it is evenly heated, thereby improving its fermentation effect and efficiency.

[0003] However, in the above application, when livestock and poultry manure is heated and fermented, the inside of the fermentation barrel is sealed and at a certain temperature. In addition, the gas generated by the fermentation of livestock and poultry manure will gradually increase the pressure inside the fermentation barrel. If the pressure inside the fermentation barrel is not relieved, on the one hand, it will affect the fermentation efficiency. On the other hand, the fermentation barrel will continue to expand under high pressure, which may cause the fermentation barrel to rupture, and even explode in extremely short cases.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0027] Example 1

[0028] Based on the problem that the pressure inside the existing fermentation barrel cannot be discharged, which may cause the fermentation barrel to rupture, this embodiment provides a fermentation device for rapid decomposition of livestock and poultry manure, please refer to Figure 1-Figure 5 The embodiment provides a fermentation device for rapid composting of livestock and poultry manure, which is capable of adaptively adjusting the internal pressure of the fermentation barrel. The fermentation device for rapid composting of livestock and poultry manure includes a fermentation tank 2 mounted on a base plate 1. The fermentation tank 2 is provided with a pressure relief mechanism 3 that automatically adjusts the pressure inside the fermentation tank 2. The fermentation tank 2 is provided with a fermentation mechanism 4 that mixes the livestock and poultry manure and promotes fermentation. The pressure inside the fermentation tank 2 is automatically adjusted and relieved by the pressure relief mechanism 3. The deodorization component 305 is provided to purify and deodorize the gas discharged by the pressure relief. The livestock and poultry manure inside the fermentation tank 2 is mixed with the fermentation agent by the fermentation mechanism 4 to improve the fermentation efficiency. The fermentation mechanism 4 is used to drive the fermentation tank 2 as a whole to rotate in conjunction with the tumbling component 405, further improving the mixing effect.

[0029] Since the pressure inside the fermentation barrel in the prior art cannot be discharged, which may cause the fermentation barrel to rupture, the device is provided with a pressure relief mechanism 3, which includes a pressure relief pipe 301 installed on the top of the fermentation tank 2, a telescopic spring 302 installed inside the pressure relief pipe 301, a rubber pad 303 slidably connected to the inner wall of the pressure relief pipe 301 installed at the bottom of the telescopic spring 302, a pressure relief hole 304 is opened at the end of the pressure relief pipe 301, and a deodorizing component 305 for purifying the fermentation odor is provided outside the pressure relief pipe 301. The tube 301 is a door-shaped structure, and the telescopic spring 302 is installed at the bend of the pressure relief tube 301. The diameter of the rubber pad 303 is the same as the inner diameter of the pressure relief tube 301. When the pressure inside the fermentation tank 2 is too high, the high-pressure gas impacts the telescopic spring 302 to stretch it, thereby pushing the rubber pad 303 down to the bottom of the pressure relief hole 304 opened on the pressure relief tube 301, so that the pressure is discharged through the pressure relief hole 304, avoiding the excessive pressure inside the fermentation tank 2 and causing the tank body to rupture, and there is no need for manpower to pay real-time attention to the pressure inside the fermentation tank 2.

[0030] Since the fermentation of livestock and poultry manure will produce odor, direct discharge will pollute the fermentation environment. Therefore, the device is also provided with a deodorization component 305, which includes a water washing box 3051 installed on the top of the fermentation tank 2, and the end of the pressure relief pipe 301 extends into the interior of the water washing box 3051. An exhaust pipe 3052 is installed on the water washing box 3051, and an activated carbon plate 3053 is plugged into the plug-in slot opened on the back of the exhaust pipe 3052. The exhausted gas is washed and purified by pure water inside the water washing box 3051, and the water-soluble harmful substances in the gas are purified, and the odor can be eliminated to a certain extent. The gas after water washing and purification is discharged through the exhaust pipe 3052, and the gas passes through the activated carbon plate 3053 inside the exhaust pipe 3052. The activated carbon plate 3053 again adsorbs and eliminates the odor in the gas, thereby preventing the fermentation gas odor from diffusing in the fermentation site and polluting the environment.

[0031] Since it is necessary to add a fermentation-promoting bacterial agent during the fermentation of livestock and poultry manure, the device is also provided with a fermentation mechanism 4 for quickly mixing the fermentation bacterial agent with the feces. The fermentation mechanism 4 includes a stirring shaft 401 rotatably connected to the inside of the fermentation tank 2, and stirring rods 402 are equidistantly and staggeredly installed on the stirring shaft 401. A stirring plate 403 is obliquely installed on the stirring rod 402. A mixing motor 404 for driving the stirring shaft 401 to rotate is installed on the right side of the fermentation tank 2, and a rolling assembly 405 for driving the fermentation tank 2 to rotate is provided on the outside of the fermentation tank 2. A scraping assembly 406 for scraping feces off the inner wall of the fermentation tank 2 is installed on the stirring shaft 401. Starting the mixing motor 404 drives the stirring shaft 401 to rotate, thereby driving the stirring rod 402 on the stirring shaft 401 to rotate to mix and stir the fermentation bacterial agent and feces. In combination with the stirring plate 403 obliquely installed on the stirring rod 402, stirring and mixing can be performed better and faster.

[0032] In order to further improve the mixing efficiency of the fermentation agent and feces, the device is also provided with a rolling assembly 405, which includes two sets of bearing seats 4051 installed on the bottom plate 1 in front and back, and a rotating shaft 4052 is rotatably connected between the two bearing seats 4051. A driving gear 4053 is installed on the left and right sides of the rotating shaft 4052. A meshing gear 4054 meshing with the driving gear 4053 is installed on the left and right sides of the fermentation tank 2. A driving rotating shaft 4052 is installed on the bearing seat 4051. 052 rotates the drive motor 4055. When the stirring rod 402 and the stirring plate 403 mix and stir the feces and fermentation bacteria inside the fermentation tank 2, the drive motor 4055 is started to drive the rotating shaft 4052 to rotate inside the bearing seat 4051, thereby driving the active gear 4053 on the rotating shaft 4052 to rotate, and then driving the meshing gear 4054 to rotate to drive the fermentation tank 2 to rotate, and the stirring is opposite to the stirring of the stirring rod 402 and the stirring plate 403, thereby further improving the stirring and mixing effect.

[0033] Since the fermentation of livestock and poultry manure needs to be maintained at a certain temperature for sterilization and to promote the fermentation process, the device has an installation cavity equidistantly opened in a circular shape inside the fermentation tank 2, and an electric heating plate 5 is installed inside the installation cavity. The electric heating plate 5 is used to heat the manure inside the fermentation tank 2 and maintain it at a certain temperature, thereby promoting the fermentation process of livestock and poultry manure and disinfecting pathogens in the manure.

[0034] Example 2

[0035] On the basis of Example 1, Figure 1-Figure 5 As shown, based on the existing electric heating plate 5, the fermentation tank 2 is continuously heated and maintained at a constant temperature. The livestock and poultry manure itself has a certain viscosity. When the manure adheres to the inner wall of the fermentation tank 2 and is continuously heated, the manure may be burnt, thereby affecting the fermentation of the manure. Therefore, the device is also provided with a scraper assembly 406, which includes a connecting rod 4061 installed on the left and right sides of the stirring shaft 401. The outer end of the connecting rod 4061 is installed with a scraper 4062, and the scraper 4062 is closely attached to the inner wall of the fermentation tank 2. As the stirring shaft 401 rotates, the scraper 4062 at the outer end of the connecting rod 4061 on the stirring shaft 401 is driven to rotate together, thereby scraping off the manure on the inner wall of the fermentation tank 2, avoiding the manure adhered to the inner wall of the fermentation tank 2 from being continuously heated and burnt, thereby affecting the fermentation process of the manure.
