Heating heat exchange device

Abstract

The invention discloses a heating heat exchange device which is composed of a shell, an inner bin and a heat conduction working medium. The inner bin is wrapped by the shell, and the distance between the shell and the inner bin is 5-150 mm. The inner bin is composed of a bin body, a heat dissipation vertical pipe, a sealing cover, a conduction shaft and a spiral blade. The conduction shaft in the position, on the larger end of the inner bin, of the bin body can drive the inner bin to rotate. An exhaust port is formed in the upper surface of the sealing cover. The spiral blade and the heat dissipation vertical pipe are arranged on the bin body of the inner bin. Heat exchange of the heating heat exchange device is three-dimensional heat exchange of an inner wall. Under the condition of the same space volume, the heat exchange area of the heating heat exchange device is increased by 8-50 times, the high-temperature heat conduction working medium conducts heat conduction and dissipation through the bin body and the heat dissipation vertical pipe of the inner bin, the heat conduction and heat exchange speed of heat energy is increased, the material drying efficiency is improved, and the purpose of fast drying materials is achieved; and the heat dissipation vertical pipe and the spiral blade have the function of material stirring, so that the wet materials are not prone to being agglomerated in the drying process, and the drying quality of the materials is optimized.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a heating heat exchange device for drying equipment. Background technique [0002] Nowadays, in the production fields of grain, food, chemical industry, medicine, etc., it is necessary to dry and dry materials; most of the heat exchange devices of drying equipment on the market now use pipe-type heat dissipation and layer heating for heat exchange. Heat dissipation, but their heat exchangers are large in size, small in heat exchange area, and low in efficiency of heat energy use; wet materials are prone to agglomeration during the drying process, resulting in uneven drying of wet materials, and many dead spots for drying materials, which comprehensively affect materials drying quality. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies in the prior art, and provide a heating and heat exchange device on the basis of the ...
