It should be noted that, compared with the conventional heat conduction type heating, the dissipation is large, the heat conduction speed is low, and the efficiency is low, the present invention is characterized in that the hot air pipes 51 are uniformly distributed in the accommodating space 210, that is, the heat distribution type heating that directly distributes the heat to the material is adopted, so the energy cost (the electricity cost required by processing each ton of dirt) of the present invention is reduced to one tenth of that of the conventional extruding and stirring horizontal fermentation tank, and the effect of reducing the energy consumption is achieved.

In operation, the dirt in the accommodating space 210 moves in two ways:

first, the second shaft moves back and forth along the second axis L2.

Through the back and forth movement of the piston rod 313 of the swing set 31 relative to the cylinder 312, the piston rod 313 drives the swing bracket 12 and the fermentation unit 2 to swing back and forth around the first axis L1, so that the dirt in the accommodating space 210 of the fermentation tank 21 moves back and forth along the second axis L2 to achieve the back and forth convection effect. For example: when the fermenter 21 swings to the dotted line portion as shown in fig. 10, the dirt flows from the end of the tank 211 opposite to the lid set 23 to the end adjacent to the lid set 23, and when the fermenter 21 swings to the dotted line portion as shown in fig. 10, the dirt flows from the end of the tank 211 adjacent to the lid set 23 to the end opposite to the lid set 23. It should be noted that, since the second axis L2 is not parallel to the front-back direction X1, the dirt can move along the up-down direction X3 and the front-back direction X1.

Second, the movement is performed along the vertical direction X3 and the horizontal direction X2

The driving member 322 of the rotating set 32 drives the gears 321 to rotate, so as to drive the racks 221 engaged with the gears 321 to rotate, so that the fermentation tank 21 rotates around the second axis L2, thereby enabling the contaminants in the accommodating space 210 of the fermentation tank 21 to move back and forth along the vertical direction X3 and the horizontal direction X2, and preferably, the blades 41 are arranged to achieve convection stirring between the center and the edge of the tank 211.

Through the foregoing, the present invention has the following effects:

1. because the dirt in the accommodating space 210 can move in three dimensions of the vertical direction X3, the horizontal direction X2 and the front-back direction X1, that is, a rotary stirring manner rather than a squeezing stirring manner is adopted, the dirt can be mixed and fermented more sufficiently, rapidly and uniformly, the fermentation efficiency is high, the production efficiency is improved, and meanwhile, the production period is reduced, and the energy consumption (about one tenth of that of the traditional squeezing stirring horizontal fermentation tank 21) is reduced.

4. By arranging the hot air pipes 51 uniformly distributed in the accommodating space 210, a heat distribution type heating manner capable of uniformly and rapidly heating is adopted, and the dirt is directly heated by hot air flow, so that the energy consumption is further reduced, and the effect of saving energy is achieved.

5. The space integration degree is high, so the land cost can be reduced, and the effect of reducing the investment cost is achieved.
