[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technology in the embodiments of the utility model, a biomass energy fermentation gas production device. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 3 As shown, the utility model provides a technical solution: a biomass energy fermentation gas production device, including a shell 1, a heat dissipation shell 4 is provided at the bottom of the shell 1, a fermentation chamber 3 is provided inside the shell 1, a motor 7 is fixedly installed on the top of the shell 1, the output end of the motor 7 passes through the top cover of the shell 1 and is connected to a rotating shaft 8, the rotating shaft 8 is placed in the fermentation chamber 3, the other end of the rotating shaft 8 is movably installed in a bearing 16, and three groups of bowl-shaped rotating stirring devices are installed around the outer surface of the rotating shaft 8, which are the first rotating disk 12, the second rotating disk 13 and the third rotating disk 14 in sequence, the bearing 16 is fixedly welded to the upper side of the connecting plate 17, and the two ends of the connecting plate 17 are welded to the inner walls of the two ends of the shell 1. A plurality of cutting strips 15 are excavated on each group of bowl-shaped rotating stirring devices, and the three groups of bowl-shaped rotating stirring devices have the same structure but different sizes, and the first rotating disk 12, the second rotating disk 13 and the third rotating disk 14 installed on the rotating shaft 8 in sequence increase in shape and size in sequence. Start the motor 7, and the shaft 8 drives the three groups of bowl-shaped rotating stirring devices to keep the biomass in motion in the fermentation chamber 3. The main performance is: after the biomass enters the fermentation chamber 3, it will first fall into the first rotating disk 12 under the action of gravity. Since the diameter of the first rotating disk 12 is smaller than that of the second rotating disk 13, part of the biomass falls on the second rotating disk 13. At the same time, the shaft 8 rotates, forcing the three groups of bowl-shaped rotating stirring devices to do circular motion, which will generate centrifugal force on the biomass falling into the rotating disk. Combined with the gravity of the biomass itself, the biomass can be fully active in the fermentation chamber 3, the gap between the biomass is increased, the reaction time of biomass fermentation is reduced, and the efficiency of energy fermentation is improved.

[0020] For details, please refer to Figure 1 and Figure 3As shown, a plurality of groups of fans 18 are installed on the connecting plate 17, and a cooling chamber 19 is provided just below the connecting plate 17. A serpentine cooling tube 20 is installed in the cooling chamber 19. Both ends of the serpentine cooling tube 20 are connected to a guide tube 21. The ends of the two groups of guide tubes 21 away from the serpentine cooling tube 20 are penetrated and extended into the liquid storage tank 5. The liquid storage tank 5 is installed inside the heat dissipation shell 4. The serpentine cooling tube 20 is provided with a liquid inlet end and a liquid outlet end, which are respectively provided on the two groups of guide tubes 21. The lower half of the liquid storage tank 5 is placed in the air, so as to facilitate the timely replacement of the refrigerant.

[0021] In this embodiment, the serpentine refrigeration tube 20 installed in the cooling chamber 19 greatly increases the heat dissipation area of ​​the cooling device. The guide tube 21 can enable the serpentine refrigeration tube 20 to always maintain a specific temperature state, ensure the stability of the biomass energy fermentation environment, and avoid affecting the activity of microorganisms such as anaerobic bacteria. The fan 18 placed above the serpentine refrigeration tube 20 can increase the cooling area and give full play to the heat dissipation effect of the refrigeration device, so that the overall temperature of the fermentation chamber 3 remains uniform, thereby improving the gas production quality of biomass energy and facilitating the collection of high-quality gas.

[0022] For details, please refer to Figure 1 As shown, an air pump 9 is installed on the top of the shell 1, and the air pump 9 is installed and acts on the air outlet pipe 10, one end of which passes through the top of the shell 1 and extends into the fermentation chamber 3, and the other end of the air outlet pipe 10 extends into and is connected to the gas storage tank 11. The bottom of the gas storage tank 11 is fixed to the upper surface of the bracket 2, and the bracket 2 is welded to the bottom of the shell 1. A feed port 6 is dug on the top of the shell 1.

[0023] In this embodiment, when the biomass energy is fermented, as the fermentation reaction of the biomass in the fermentation chamber 3 occurs, the corresponding gas is also gradually generated. At this time, starting the air pump 9 can accelerate the collection reaction of the gas, separate and store the gas in time, and to a certain extent provide the biomass energy with sufficient reaction space, thereby improving the fermentation efficiency.
