[0040] The utility model provides a stirring mechanism and a fermentation tank. During the fermentation process, the stirring rod 1 rotates under the driving action of the stirring motor 2, and at the same time drives the lifting stirring blade 3 to rotate, so as to stir the fermented material by the lifting stirring blade 3; moreover, since the lifting stirring blade 3 is spiral, it also has the function of lifting the material upward while stirring the material (wherein a cover is provided on the top of the tank body 23 to prevent the material from being thrown out of the tank body 23), so that materials at different heights can flow to each other, and even solid materials such as straw and phosphogypsum can be distributed more evenly and dispersedly, so that the whole The fermentation effect is better; not only that, when water replenishment is needed, water is directly added to the containing tank through the water replenishment mechanism, so that the water is discharged outward into the material through the water outlet 4; in actual use, the stirring rod 1 can be either not rotated during water replenishment or rotated during water replenishment, wherein it is preferred that the stirring rod 1 rotates during water replenishment, so that the water can act on the flowing material, thereby improving the overall water replenishment uniformity of the material; at the same time, since the stirring rod 1 is deeply inserted into the material, the water outlet 4 can replenish water to a wider range at the same time, the water replenishment uniformity is better, and the water replenishment effect is also better, which makes the fermentation effect better.

[0041] In actual use, when stirring is required, first the stirring motor 2 drives the transmission column 20 to rotate, and the transmission column 20 drives the two active sprockets 18 to rotate, and at the same time, the two active sprockets 18 respectively drive the two driven sprockets 17 to rotate through the transmission chain 19, so that the stirring rod 1 can be driven to rotate; because the two driven sprockets 17 are located at the top and bottom of the stirring rod 1, the stirring rod 1 can be rotated better to prevent it from deformation. At the same time, the outer wall of the stirring rod 1 is also supported by the first stabilizing cylinder 26 and the second stabilizing cylinder 27, so that the position and shape stability of the stirring rod 1 are better.

[0042] During the stirring process, the auxiliary rod 21 and the auxiliary stirring plate 22 on the outer wall of the stirring rod 1 can also play a role in stirring and driving the peripheral materials, thereby making the material uniformity in the entire tank body 23 better.

[0043] When the stirring rod 1 is rotating, the water supply pipe 6 and the stirring rod 1 are relatively stationary, and the water supply pipe 6 and the water adding pipe 5 are sealed and rotatably connected, so the rotation of the water supply pipe 6 can not drive the water adding pipe 5 to rotate; then when water is needed, the stirring rod 1 needs to be stopped first, and then the worker raises the positioning sleeve 14 which is now sleeved on the positioning column 11, and makes the top of the positioning sleeve 14 adsorbed on the corresponding operating part 16; then the operating handle 13 is rotated through the operating part 16 until the positioning column 11 contacts the other end of the adjusting groove 12, and then moves downward. Move the positioning sleeve 14 at the corresponding position until the positioning sleeve 14 is sleeved onto the positioning column 11 through the positioning hole 15 (at this time, the positioning sleeve 14 is far away from the operating part 16 and the positioning sleeve 14 cannot be sucked up). In this way, the adjustment of the angle between the water supply pipe 6 and the stirring rod 1 is completed. At this angle, all the water holes 7 are directly opposite to the corresponding water outlet holes 4. At the same time, under the action of the positioning sleeve 14, the angle of the water supply pipe 6 and the stirring rod 1 is kept stable. Under the action of the anti-detachment disk 9, the anti-detachment part 10 and the rotating disk 8, the upper and lower positions of the water supply pipe 6 and the stirring rod 1 are relatively stable.

[0044] Then the water pump pumps water into the water supply pipe 5. After the water enters the water supply pipe 6, it passes through the water hole 7 and the water outlet hole 4, enters the tank body 23, and acts evenly on the lifted material. Since the cross section of the operating handle 13 is rectangular, when the positioning sleeve 14 is raised or lowered, its angle is stable, which is not only convenient for buckling onto the positioning column 11, but also can well maintain the relative angle between the water supply pipe 6 and the stirring rod 1 stable after the buckling is completed.

[0045] After the fermentation is completed, if there is liquid inside the tank body 23, the control valve 29 is opened to discharge the liquid in the tank body 23 or put it into a container for use; at the same time, the filter screen 30 can better prevent impurities or particles from entering the discharge pipe 28; finally, when the solid matter is taken out from the tank body 23, it can be taken out directly from the top, and the material can also be taken out after opening the discharge door 31; there is a sealing ring between the discharge door 31 and the tank body 23, and the discharge door 31 and the tank body 23 are tightly connected by bolts.

[0046] When cleaning the stirring rod 1 and the water supply pipe 6 regularly, first remove the stabilizing bolt, then remove the sealing rod 32, and finally rotate the water supply pipe 6 to make the water hole 7 and the water outlet hole 4 misaligned, and then inject high-pressure water into the water supply pipe 6 through the water supply pipe 5, so that the impurities in the water supply pipe 6 can be flushed out. Since the sealing rod 32 and the stirring rod 1 are threadedly connected, the position stability of the sealing rod 32 can be maintained after the stabilizing plate 33 and the matching plate 34 are connected by the stabilizing bolt.

[0047] In yet another embodiment, Fig.12As shown, there is also a vertically downward movable pin on the top of the matching disk 34, and a spring that is always in a compressed state is provided on the top of the movable pin; at the same time, there is a hole for inserting the movable pin on the stabilizing disk 33; in this way, the position of the sealing rod 32 can be kept stable through the movable pin, so that the stirring rod 1 and the water supply pipe 6 can work normally and can be cleaned normally.

[0048] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
