[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is active on connecting parts such as hinges, pins and short shafts.

[0019] The intermediate is placed in the conveying cylinder 2 through the hopper 1, and the power of the liquid inlet pipe 3 is turned on. The liquid inlet pipe 3 drives the spiral blade 4 to rotate and convey the intermediate to the stirring mechanism. After the stirring is completed and the material is discharged, cleaning and disinfection are started. Disinfectant is injected into the liquid inlet pipe 3 through the liquid pump, and the disinfectant is sprayed out through the nozzle 5. The nozzle 5 rotates with the liquid inlet pipe 3 to achieve full coverage and disinfection of the inner wall of the conveying cylinder 2. The disinfectant sprayed on the top wall of the conveying cylinder 2 is drained by the protrusion 7 and drips on the surface of the spiral blade 4 and the liquid inlet pipe 3, cleaning the spiral blade 4 and the liquid inlet pipe 3 to achieve cleaning without dead angles. The residue and the disinfectant are transported and discharged into the agitator by the spiral blade to disinfect the agitator.

[0020] The connection surface of the projection 7 is a regular quadrilateral, and the shape is a quadrangular pyramid pointing vertically downward;

[0021] The four-sided pyramidal protrusions 7 are arranged without gaps, so that the disinfectant on the top wall can be drained through the protrusions 7, preventing the disinfectant from flowing toward the side wall of the conveying tube 2 along the gaps.
