[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Example 1
[0026] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a biological fertilizer fermentation device. The biological fertilizer fermentation device includes a fermentation tank 1, a feeding port 2 at the top of the fermentation tank 1, a steam inlet 3 on the outer surface of the fermentation tank 1, a steam outlet 4 on the outer surface of the fermentation tank 1 away from the steam inlet 3, a feeding port 5 at the bottom of the fermentation tank 1, a gas injection component 6 inside the fermentation tank 1, and an exhaust filter component 7 at the top of the fermentation tank 1.
[0027] The gas injection assembly 6 includes a first filter box 61, which is located at the top of the fermenter 1. The first filter box 61 has an air inlet channel 62 at its top and a high-efficiency filter 63 inside. The high-efficiency filter 63 has a sealing plate 64 at its top and a handle 65 at its top. A gas dispersion mechanism is provided on one side of the first filter box 61, and a stirring and mixing mechanism is provided inside the fermenter 1. Gas is injected into the first filter box 61 through the air inlet channel 62, and then the injected gas passes through the high-efficiency filter 63 to reach the gas dispersion mechanism. The high-efficiency filter 63 can filter out other bacteria in the injected gas.
[0028] The mixing mechanism includes a U-shaped plate 671, which is located on the top of the fermentation tank 1. A motor 672 is located on the top of the U-shaped plate 671, and the output end of the motor 672 is connected to a stirring shaft 673. The stirring shaft 673 extends into the fermentation tank 1 and is equipped with a spiral stirring blade 674. A secondary stirring frame 675 is located at the bottom of the stirring shaft 673, and a U-shaped scraper 676 is located on the outside of the secondary stirring frame 675. The U-shaped scraper 676 is in close contact with the inner wall of the fermentation tank 1. The motor 672 drives the stirring shaft 673 to rotate, which in turn drives the secondary stirring frame 675 to rotate. The secondary stirring frame 675 drives the U-shaped scraper 676 to rotate along the inner wall of the fermentation tank 1. The U-shaped scraper 676 scrapes away the residue on the inner wall of the fermentation tank 1, which helps with the subsequent cleaning of the fermentation tank.
[0029] The gas dispersion mechanism includes a transfer box 661, which is located at the top of the fermenter 1. A connecting pipe 662 is provided between the transfer box 661 and the first filter box 61. A stirring shaft 673 passes through the transfer box 661 and is rotatably connected to the transfer box 661. There is a good seal between the stirring shaft 673 and the transfer box 661. A gas inlet 663 is provided on the stirring shaft 673 and is located inside the transfer box 661. A secondary stirring frame 675 is provided with several gas outlets 664. Gas flow channels are provided inside both the stirring shaft 673 and the secondary stirring frame 675. The filtered gas reaches the transfer box 661, then enters from the gas inlet 663, and then is sprayed out from the several gas outlets 664, dispersing and delivering the gas to different locations of the microbial fertilizer, so that the microbial fertilizer in different locations can fully contact the gas, which is conducive to production.
[0030] During operation, the operator starts the motor 672, which drives the stirring shaft 673 to rotate. The stirring shaft 673 then drives the spiral stirring blades 674 to rotate, simultaneously rotating the auxiliary stirring frame 675. The spiral stirring blades 674 and the auxiliary stirring frame 675 thoroughly mix the microbial fertilizer. Next, gas is injected into the first filter box 61 through the air inlet channel 62. The injected gas then passes through the high-efficiency filter 63 to the gas dispersion mechanism. The high-efficiency filter 63 removes other microorganisms from the injected gas. The filtered gas then travels through the connecting pipe 662 to the transfer box 661. Gas enters through gas inlet 663, passes through the channels inside the stirring shaft 673 and auxiliary stirring rack 675, and is then ejected from several gas outlets 664, dispersing and delivering the gas to different locations of the microbial fertilizer. This ensures that the microbial fertilizer in different locations can fully contact the gas, which is beneficial for production. When cleaning the fermentation tank 1 after fermentation, the auxiliary stirring rack 675 is rotated by motor 672. The auxiliary stirring rack 675 drives the U-shaped scraper 676 to rotate along the inner wall of the fermentation tank 1. The U-shaped scraper 676 scrapes the residue on the inner wall of the fermentation tank 1, which helps with the subsequent cleaning of the fermentation tank and prevents contamination for the next fermentation.
[0031] Example 2
[0032] Reference Figures 1-4This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that the exhaust filter assembly 7 includes a vertical column 75, which is located at the top of the fermentation tank 1 and is in communication with the fermentation tank 1. A piston 76 is located inside the vertical column 75, and a sliding shaft 77 is located at the top of the piston 76. A spring 78 is fitted onto the outer surface of the sliding shaft 77, and a circular plate 79 is located at the top of the sliding shaft 77. A purification mechanism is located on one side of the vertical column 75. The fermentation gas is driven by the piston 76 to move the sliding shaft 77 along the vertical column 75, and then the fermentation gas passes through the gas channel 74 to reach the second filter chamber 71, thus realizing automatic pressure relief of the fermentation tank 1 without manual intervention.
[0033] The purification mechanism includes a second filter chamber 71, which is located at the top of the fermenter 1. The top of the second filter chamber 71 is provided with an exhaust channel 72. An activated carbon plate 73 is provided inside the second filter chamber 71. A gas channel 74 is provided between the second filter chamber 71 and the vertical column 75, and the gas channel 74 is interconnected with the second filter chamber 71 and the vertical column 75. The activated carbon plate 73 filters harmful substances in the fermentation gas to avoid environmental pollution.
[0034] The sliding shaft 77 is slidably connected to the vertical column 75, and the spring 78 is located between the piston 76 and the vertical column 75. The spring 78 can drive the piston 76 back to the initial position.
[0035] During use, when the pressure in fermenter 1 is too high, the fermentation gas is driven by piston 76 to move the sliding shaft 77 along the vertical column 75. After piston 76 moves above gas channel 74, the fermentation gas will pass through gas channel 74 to the second filter chamber 71, be filtered by activated carbon plate 73 and discharged from exhaust channel 72, realizing automatic pressure relief without manual operation. At the same time, the adsorption of activated carbon plate helps to protect the environment.
[0036] The remaining structure is the same as that in Example 1.
[0037] Based on embodiments 1-4, the working principle of this utility model is as follows: The operator adds raw materials into the fermentation tank 1 through the feed inlet 2. Then, steam is injected through the steam inlet 3 and discharged through the steam outlet 4, thus heating the fermentation tank 1. Next, the operator starts the motor 672, which drives the stirring shaft 673 to rotate. The stirring shaft 673 drives the spiral stirring blades 674 to rotate, and simultaneously drives the auxiliary stirring frame 675 to rotate. The spiral stirring blades 674 and the auxiliary stirring frame 675 thoroughly mix the microbial fertilizer. Then, gas is injected into the first filter box 61 through the air inlet channel 62. The injected gas then passes through the high-efficiency filter 63 to reach the gas dispersion mechanism. The high-efficiency filter 63 filters out other bacteria in the injected gas. The filtered gas reaches the transfer box 661 through the connecting pipe 662, then enters through the gas inlet 663, passes through the channels inside the stirring shaft 673 and the auxiliary stirring frame 675, and is then ejected from several gas outlets 664, dispersing the gas... The microbial fertilizer is dispersed and transported to different locations, ensuring that the microbial fertilizer in each location can fully contact the gas, which is beneficial to production. During fermentation, when the pressure in fermenter 1 is too high, the fermentation gas is driven by piston 76 to move the sliding shaft 77 along the vertical column 75. After piston 76 moves above gas channel 74, the fermentation gas will pass through gas channel 74 to the second filter chamber 71, be filtered by activated carbon plate 73, and discharged from exhaust channel 72, realizing automatic pressure relief without manual intervention. At the same time, the adsorption of activated carbon plate helps to protect the environment. After pressure relief, the piston 76 is driven back to the initial position by the tension of spring 78. When cleaning fermenter 1 after fermentation, motor 672 drives auxiliary stirring frame 675 to rotate. Auxiliary stirring frame 675 drives U-shaped scraper 676 to rotate along the inner wall of fermenter 1. The U-shaped scraper 676 scrapes the residue on the inner wall of fermenter 1, which helps to clean the fermenter and prevents contamination of the next fermentation.
