Based on the embodiments of 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. Embodiment 1

[0028] See also Figure 1 - Figure 4The utility model provides a biological fertilizer fermentation device, comprising an L-shaped fixing frame 1 and a fermentation tank 2 installed on the fixing frame 1, wherein a heating mechanism and a stirring mechanism are arranged in the fermentation tank 2, wherein a top cover on the top of the fermentation tank 2 is connected by bolts, so that the fermentation tank 2 can be easily disassembled and opened to clean and maintain the inside thereof;

[0029] A pressure relief valve 3 fixedly mounted on the front side of the top of the fermentation tank 2;

[0030] A filter tube 4 is threadedly connected to the exhaust end of the pressure relief valve 3 and has a T-shaped cross section, and a limit ring 5 is fixedly connected to the inner bottom end of the filter tube 4;

[0031] A filter cotton 6 is arranged on the limiting ring 5;

[0032] An activated carbon block 7 disposed on the filter cotton 6;

[0033] and an exhaust cover 8 threadedly connected to the inside of the top port of the filter tube 4, and a handle is fixedly installed on the top of the exhaust cover 8;

[0034] A feed pipe 9 is fixedly installed on one side of the top of the fermenter 2, and a discharge pipe 10 is fixedly installed on the bottom of the fermenter 2. A valve 11 is provided on the surface of the discharge pipe 10. Opening the valve 11 facilitates the discharge of the fermented material in the fermenter 2 through the discharge pipe 10.

[0035] The technical solution provided in this embodiment is as follows: when in use, the fermented material is added into the fermentation tank 2 through the feed pipe 9, and the fermented material is subjected to auxiliary fermentation treatment by means of the heating mechanism and the stirring mechanism. During the fermentation process, the excess gas in the fermentation tank 2 is conveniently discharged through the pressure relief valve 3 to ensure the pressure inside the fermentation tank 2. The discharged gas enters the filter tube 4, and the filter cotton 6 is used to preliminarily filter the particulate impurities contained in the gas. The gas then passes through the activated carbon block 7 to make it contact the surface of the activated carbon block 7, so that under the action of the activated carbon block 7, the impurities such as odor and organic compounds in the gas are again adsorbed, filtered and purified. Finally, the filtered and purified gas is discharged through the exhaust cover 8. Therefore, the effect of purifying and filtering the gas discharged from the fermentation is achieved, thereby preventing the gas from polluting the working environment and the health of personnel, and effectively improving the air quality of the working environment and the health and safety of personnel.

[0036] When replacing the filter cotton 6 and the activated carbon block 7, rotate the filter tube 4 to disassemble it, hold the handle to rotate and disassemble the exhaust cover 8 to open the filter tube 4, and then take out the activated carbon block 7 and the filter cotton 6 for replacement. When installing, first put the filter cotton 6 into the filter tube 4, and block and limit it with the limiting ring 5, then put the activated carbon block 7 into the filter tube 4, and finally screw on the exhaust cover 8, which is convenient for regular replacement of the filter cotton 6 and the activated carbon block 7, so as to maintain the filtering effect of the filter cotton 6 and the adsorption performance of the activated carbon block 7.

[0037] Further, the heating mechanism includes a steam nozzle 15 provided at the inner bottom of the fermentation tank 2 and an intake valve 16 provided on one side of the discharge pipe 10. The outlet end of the intake valve 16 penetrates into the fermentation tank 2 through a conduit and is connected to the steam nozzle 15.

[0038] A plurality of spray holes are formed on the surface of the steam nozzle 15, and filter plates are fixedly installed in the spray holes.

[0039] Specifically, during fermentation, an external steam delivery pipe is connected to the intake valve 16, and the input steam is input into the steam nozzle 15 through the conduit and ejected through the spray holes, so as to achieve the effect of heating and fermenting the fermented material with steam. At the same time, due to the arrangement of the filter plates, it can prevent the fermented material from entering the steam nozzle 15 and causing blockage of the steam nozzle 15, which affects the jetting effect.

[0040] Further, the stirring mechanism includes a stirring rod 12 fixedly installed and rotatably connected to the inner top wall of the fermentation tank 2, a plurality of stirring blades 13 fixedly installed on the surface of the stirring rod 12, and a power member provided at the top of the fermentation tank 2.

[0041] The power member includes a motor 14 fixedly installed at the top of the fermentation tank 2, and the output end of the motor 14 passes through the fermentation tank 2 and is connected to the stirring rod 12.

[0042] Specifically, during fermentation, the motor 14 drives the stirring rod 12 and the stirring blades 13 to rotate, and the stirring blades 13 are used to stir the fermented material, so as to achieve the purpose of stirring the fermented material, facilitating the uniform heating of the fermented material, and improving the fermentation efficiency and effect of the fermented material.

[0043] Further, two groups of fixed sleeves 17 are symmetrically and fixedly installed on both sides of the surface of the fermentation tank 2. Two groups of triangular support frames 18 are symmetrically and fixedly installed on one side surface of the vertical section of the fixed frame 1. A clamping block inserted into the fixed sleeve 17 is fixedly installed at the top of the triangular support frame 18. Among them, the fixed sleeve 17 has a "C" - shaped structure.

[0044] Specifically, when installing the fermentation tank 2, the fermentation tank 2 is moved to align the fixed sleeve 17 with the clamping block on the triangular support frame 18, and then the fermentation tank 2 is moved downward so that the fixed sleeve 17 is sleeved on the clamping block and clamped and fixed thereto, achieving the purpose of installing and fixing the fermentation tank 2. On the contrary, moving the fermentation tank 2 upward to separate the fixed sleeve 17 from the clamping block can be disassembled, which is convenient for subsequent maintenance of the fermentation tank 2.
