At the same time, an oxygen control device can be installed in the fermentation area 4 as needed.
[0029] The structures of the material transfer assembly and the material discharge assembly in this embodiment are described in detail below:
[0030] (1) Material transfer components
[0031] The material transfer assembly in this embodiment includes a first guide plate 81 and a second guide plate 82 that are arranged opposite to each other, and a rotating plate 83 .
[0032] The horizontal height of the first guide plate 81 gradually decreases from the side close to the crushing device 3 to the side close to the second guide plate 82. The inclination direction of the second guide plate 82 is opposite to that of the first guide plate 81. The second guide plate 82 is used to transport the material from the first guide plate 81 to the middle position of the fermentation area 4. The rotating plate 83 is used to conduct the passage formed between the fermentation area 4 and the end of the second guide plate 82 and the first guide plate 81 for discharging the material. A discharge passage is formed between the second guide plate 82 and the first guide plate 81 to transport the material from the first guide plate 81 to the middle position of the fermentation area 4; the rotating plate 83 is rotated to open or close the discharge passage.
[0033] The first guide plate 81 and the second guide plate 82 have sawtooth-shaped blocking blocks, and the blocking blocks are arranged in an arc shape, such as Figure 1 and Figure 3As shown, the liquid can flow to both sides along the arc-shaped sawtooth bottom, while larger solids are blocked on the blocking block, and the solid waste is removed by opening a waste port on the tank body 2 to prevent it from affecting the fermentation. At the same time, the sawtooth blocking block can play a better mixing role, and the material falling into the fermentation area 4 can be relatively evenly distributed, so that the fermentation can be better performed.
[0034] The upper end of the rotating plate 83 is rotatably connected to the first guide plate 81, and the lower end of the rotating plate 83 is provided with a receiving groove near the second guide plate 82 for receiving the end of the second guide plate 82. In the non-discharging state, the end of the second guide plate 82 is received in the receiving groove.
[0035] like Figure 2 As shown, a first magnetic sheet 91 and a first sealing layer 92 wrapping the first magnetic sheet 91 are provided in the receiving groove, and a second magnetic sheet 93 and a second sealing layer 94 wrapping the second magnetic sheet 93 are provided at the end of the second guide plate 82. The first magnetic sheet 91 and the second magnetic sheet 93 attract each other so that the end of the second guide plate 82 is in close contact with the rotating plate 83 under the action of gravity. The ends of the rotating plate 83 and the second guide plate 82 are attracted to each other and fit together by the magnetic sheet, so that when there is no material transmission, the rotating plate 83 has a tendency to fit with the end of the second guide plate 82 under the action of its own gravity and magnetic force. At the same time, by providing a sealing layer, the fitting between the rotating plate 83 and the second guide plate 82 is made tighter, ensuring the airtightness of the operation process and the fermentation process. In some other embodiments of the present invention, the above-mentioned magnetic design can be replaced or assisted by providing an elastic member.
[0036] In other embodiments, a stopper is provided at the end of the second guide plate 82, and a hook that cooperates with the stopper is provided on the rotating plate 83; the cooperation between the stopper and the hook can make the connection between the second guide plate 82 and the rotating plate 83 tighter.
[0037] (2) Unloading components
[0038] like Figure 1 and Figure 5As shown, the discharge assembly in this embodiment includes a bottom plate 10 arranged at the bottom of the fermentation area 4, a discharge plate 11 rotatably arranged on the bottom plate 10, and a handle 12 for driving the discharge plate 11 to rotate. A discharge port 13 is provided on the bottom plate 10, and the discharge plate 11 is arranged corresponding to the discharge port 13. One end of the handle 12 is arranged at the bottom of the bottom plate 10, and the other end of the handle 12 extends outside the tank body 2. The tank body 2 is provided with a port for the handle 12 to move; the discharge plate 11 is driven to rotate by the handle 12. When the discharge plate 11 is placed below the discharge port 13, that is, the discharge port 13 overlaps with the discharge plate 11, the fermentation area 4 is not connected to the space below, and fermentation can be carried out. When the rotating discharge plate 11 is misaligned with the discharge port 13, the material in the fermentation area 4 flows downward through the discharge port 13 for discharge, and the material falls onto the filter plate 5 for solid-liquid separation.
[0039] The upper surface of the discharge plate 11 is a first serrated sealing surface 161, and the lower surface of the bottom plate 10 is provided with a second serrated sealing surface 162 corresponding to the discharge plate 11. The serrations in the serrated sealing surface are arc-shaped extensions, so that the first serrated sealing surface 161 and the second serrated sealing surface 162 can rotate with each other and seal.
[0040] like Figure 3 As shown, a sealing block 14 is provided on the inner wall of the tank body 2 corresponding to the end face of the discharge plate 11, and a sealing groove for accommodating the sealing block 14 is provided on the end face of the discharge plate 11 close to the inner wall of the tank body 2, and a sealing member 15 is provided between the sealing groove and the sealing block 14. The discharge plate 11 is arranged in a fan shape, and one end of its center is rotatably connected to the bottom plate 10, and the rotation axis coincides with the center of the discharge plate 11 and the center of the bottom plate 10, and the other end of the discharge plate 11 is connected to the sealing block 14. The sealing block 14 can play a supporting role on the one hand, and play a sealing role together with the end face of the discharge plate 11 on the other hand. Limiting blocks with increased size are provided at both ends of the sealing block 14, thereby limiting the rotation of the discharge plate 11.
[0041] In some other embodiments of the present invention, a sealing strip is further provided on the lower surface of the bottom plate 10 corresponding to the discharge port 13, and the sealing strip cooperates with both sides of the fan-shaped discharge plate 11 to achieve sealing, further enhancing the sealing during fermentation.
[0042] The working process of the integrated fermentation tank 1 of this embodiment is briefly described below:
[0043] First, open the feeding port 7, and feed the raw material into the crushing device 3 through the feeding port 7, and add liquid as needed. The liquid and the crushed material flow along the first guide plate 81, the second guide plate 82, and break the rotating plate 83 and fall into the fermentation area 4. When on the first guide plate 81 and the second guide plate 82, the liquid and the crushed material can flow to both sides along the serrated arc groove and flow downward step by step, while some fiber waste is left on the serrated plate to prevent it from being stuck between the rotating plate 83 and the end of the second guide plate 82, affecting the air tightness and affecting the fermentation process. The waste can then be taken out by opening the corresponding waste port.
[0044] After the materials are added, fermentation is carried out in the fermentation area 4. The rotating plate 83 is tightly attached to the end of the second guide plate 82 under the action of its own gravity and magnetic force to ensure air tightness. At the same time, the sealing surface between the bottom plate 10 of the fermentation area 4 and the discharge plate 11 and the sealing design between the sealing block 14 and the end surface of the discharge plate 11 can further ensure the sealing during fermentation.
[0045] After fermentation is completed, the fan-shaped discharge plate 11 is rotated by turning the handle 12 so that it is staggered with the discharge port 13, and the material in the fermentation area 4 falls onto the filter plate 5 for filtration to achieve solid-liquid separation. The solid is then removed through the solid feeding port, and the liquid is collected by diversion through the inclined plate 6.
[0046] After all the work is completed, pour cleaning liquid into the feeding port 7 to clean the inside of the tank body 2 to prevent the presence of impurities from affecting the air tightness of the next fermentation.
[0047] The integrated fermentation tank of the present invention crushes the material fed from the feeding port by a crushing device, and then transmits the crushed material to the fermentation area for fermentation by a material transfer component. After the fermentation is completed, the objects are placed on the filter plate for solid-liquid separation by a discharge component, and the separated solids are taken out through the solid feeding port, and the liquid is guided by the inclined plate, thereby realizing the functions of object crushing, fermentation and solid-liquid separation.
[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
