Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
The air-jet self-cleaning stirring mechanism shown in fig. 1 and 2 is the most preferred embodiment of the present invention, and comprises a stirring cylinder 5, an end cover 2, a stirring motor 1 and a stirring shaft 3, wherein the end cover 2 is connected to the stirring cylinder 5 in an opening and closing manner, the stirring motor 1 is fixed at the top of the end cover 2, the output end of the stirring motor 1 is in transmission connection with the stirring shaft 3, the stirring shaft 3 penetrates through the end cover 2 and extends into the stirring cylinder 5, and stirring blades 4 are fixed on the stirring shaft 3.
Stirring barrel 5 is cask column structure, 5 inner wall bottom circumference internal surface of stirring barrel on the symmetry be equipped with two annular gas injection pipes 7 of semicircle, two gas injection pipes 7 use 5 bottom surface centre of a circle of stirring barrel as the center, be the centrosymmetric design, 7 inner peripheral surfaces of gas injection pipe on the interval be equipped with the nozzle 6 of a plurality of and 7 inside gas circuits of gas injection pipe intercommunication, 7 outer peripheral surfaces of gas injection pipe on then be connected with intake pipe 10, intake pipe 10 run through stirring barrel 5 outer walls and be connected with to the gaseous gas compression valve that lets in the intake pipe 10. In order to avoid the chemical reaction between the introduced gas and the stirred material, the gas introduced into the gas inlet pipe 10 by the gas compression valve is inert gas. In practical use, inert gas which does not react with the stirred materials needs to be selected according to different stirred materials.
The outer peripheral surface of the gas injection pipe 7 is a vertical surface completely attached to the inner peripheral surface of the stirring cylinder 5, the connection position of the gas injection pipe 7 and the gas inlet pipe 10 is the central position of the outer peripheral surface of the gas injection pipe 7, and the gas injection pipe 7 and the gas inlet pipe 10 are of an integral structure.
