[0034] In this embodiment, the provided mixing component 7 can fully mix the raw materials and the biological enzyme, and at the same time can accelerate the heat conduction. And after the device is used up, it is convenient to cooperate with the provided rotary joint 9 and the rotating pipe 6 to spray water into the tank body 2 for cleaning, so as to avoid the long-term residue of materials from polluting the inside of the device. The provided driving component 8 is used to control the working state of the mixing component 7.

[0035] When it is necessary to mix and stir the raw materials in the tank body 2, start the water pumping equipment for the external circulating hot water. The water pumping equipment conducts the externally constant-temperature hot water to the heat conduction water pipe 18 through the set three-way pipe 11 to heat the inside of the tank body 2. At the same time, control the driving motor 81 to work. The driving motor 81 drives the rotating pipe 6 to rotate through the set driving gear 82 and driven gear 83.

When the materials in the device are completely reacted, turn off the water pumping equipment for the external circulating hot water and the driving motor 81, open the valve on the discharge pipe 13, and discharge the reacted materials through the discharge pipe 13 for collection.

[0036] When it is necessary to clean the inside of the tank body 2, control the driving motor 81 to work. The driving motor 81 drives the rotating pipe 6 and the mixing component 7 to rotate through the set driving gear 82 and driven gear 83. At the same time, inject water into the connecting pipe 10 through the external water pumping equipment box. The water enters the horizontal pipe 72 and the vertical pipe 73 through the rotating pipe 6 and is sprayed out through the nozzle 75 to clean the inside of the tank body 2 and the outside of the heat conduction shell 14. At the same time, the horizontal pipe 72 is attached to the inner wall of the tank body 2 and the outer wall of the heat conduction shell 14, and can scrape off the materials adhering to the inner wall of the tank body 2 and the outer wall of the heat conduction shell 14, and use the rotation of the horizontal pipe 72, the horizontal shaft 76 and the stirring shaft 78 to stir the water in the tank body 2 to achieve full cleaning of the inner wall of the tank body 2 and avoid internal pollution of the device caused by material residues.
