The invention provides a hot-blast air supply structure in a particle material drying and stirring device. The hot-blast air supply structure comprises a thermal insulating box and a rotary shaft in the thermal insulating box; a plate body dividing the internal cavity of the thermal insulating box into an upper cavity and a lower cavity is arranged in the thermal insulating box; a cylinder is vertically arranged in the lower cavity; a cavity is formed among the cylinder, the thermal insulating box and the plate body; an air inlet communicating the upper cavity with the cavity is formed in theplate body; the rotary shaft is hollow; the upper end of the rotary shaft communicates with the upper cavity; a concave hole is formed in the bottom wall of the thermal insulating box; the lower end of the rotary shaft penetrates through the concave hole; the side wall of the rotary shaft and the hole wall of the concave hole form seal through two second seal rings; an air cavity is formed among the side wall of the rotary shaft, the hole wall of the concave hole and the two second seal rings; a discharge port communicating the internal cavity of the rotary shaft and the air cavity is formed in the side wall of the rotary shaft; air inlet communicating with the upper cavity is formed in the top of the thermal insulating box; a first exhaust passage communicating the cavity with the external world and a second exhaust passage communicating the air cavity with the external world are arranged in the bottom wall of the thermal insulating box; and the internal cavity of the cylinder communicates with the external world through an exhaust pipe. The hot-blast air supply structure is high in drying efficiency.
Description
technical field [0001] The invention belongs to the technical field of machinery, and relates to a granular material drying and stirring device, in particular to a heating gas structure in the granular material drying and stirring device. Background technique [0002] Drying equipment is also called dryer and dryer. The equipment used for drying operation, the moisture in the material (generally refers to water or other volatile liquid components) is vaporized and escaped by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. [0003] Existing drying equipment generally heats the outside of the container and dries the material by stirring. This method does not have a very high heat transfer effect and the drying efficiency is not good. Contents of the invention [0004] The purpose of the present invention is to solve the above-mentioned problems in the existing technology...
