Rotary drying chamber with cooling section

Abstract

The invention discloses a rotary drying storehouse with a cooling section. The rotary drying storehouse consists of a housing, an inner storehouse and a heat-conducting medium, wherein the apparent shape of the rotary drying storehouse is cylindrical; the housing is arranged on the outer surface of the inner storehouse; the positions, which are in contact with the storehouse body of the inner storehouse, at the two ends of the housing are sealed into an integer by virtue of a sealing device; an inner cavity between the housing and the inner storehouse is sealed and air-proof; a heat energy inlet and a heat energy outlet are formed in the upper surface of the housing; the inner storehouse consists of a storehouse body and radiating vertical tubes, wherein charge and discharge holes are formed in the two ends of the inner storehouse; one end of the inner storehouse is a drying section, and the other end of the inner storehouse is a cooling section; heat energy carried by the high-temperature heat-conducting medium carries out heat conduction and heat exchange on materials by virtue of the storehouse body of the inner storehouse and radiating tubes, so that heat conduction and heat exchange speed of heat energy is increased due to an increased heat exchange area, and therefore, the purpose of quickly drying the materials is achieved. When the materials are dried, radiating vertical tubes which are spirally arranged have functions of stirring and pushing during rotation under action of external force, so that the material drying quality is improved, and the dried materials are cooled at the cooling section.

Description

technical field [0001] The invention relates to a drying bin, in particular to a rotary drying bin with a cooling section. Background technique [0002] Nowadays, materials such as grain, food, chemical industry, medicine, agricultural by-products, pasture and other materials need to be heated and dried in the field of processing and production; most of the heat exchange in the drying chamber of the drying equipment on the market now uses pipe-type heat dissipation and hot air convection However, their radiators are large in size, small in heat dissipation area, and low in efficiency of heat energy use. Wet materials often form agglomerates during the drying process, resulting in uneven drying of wet materials and affecting the drying quality of materials. The speed of the material in the drying chamber is not easy to control. The material is cooled in the normal pressure environment and will be affected by the humidity in the surrounding air. The dry material will be affec...
