Roller vacuum drying bin with cooling section

Abstract

The invention provides a roller vacuum drying bin with a cooling section. The roller vacuum drying bin comprises a heating bin, a drying bin, heat conduction work media and a gear ring. An externallyarranged driving device drives the gear ring on the drying bin, and the gear ring can drive the drying bin to rotate. The heating bin is arranged on the outer surface of the drying bin. The drying bincomprises a bin body, a heat dissipation vertical pipe, heat pipes, screw blades and a fixing bar. The heat pipes are an independent whole overall welded to the part, in a drying section of the drying bin, of a bin body. The two ends of the heat dissipation vertical pipe are fixed to the parts, in a cooling section of the drying bin, of the bin body. The heat conduction work media in the heat pipes are heated by heat energy carried by the heat conduction work media in the heating bin to generate phase change gasification, the heat energy carried by the gasified heat conduction work media conducts heat conduction and heat exchange through heat pipe feed, the heat conduction and heat exchange speed of the heat energy is increased through the enlarged heat exchange area, the material dryingefficiency is improved, and the purpose of fast material drying is achieved. During material drying, the screw blades have stirring and pushing functions, materials are not likely to be agglomerated when being dried in the drying bin, and the dried materials are cooled in the cooling section of the drying bin.

Description

technical field [0001] The invention relates to a drum drying bin, in particular to a drum vacuum drying bin with a cooling section. Background technique [0002] Nowadays, in the processing and production fields of grain, food, chemical industry, medicine, agricultural by-products, pasture, etc., it is necessary to heat and dry the materials under vacuum conditions; the heat exchange of the drum drying chamber of the vacuum drying equipment on the market is mostly in the form of pipes. , Interlayer heating method for heat exchange and heat dissipation, but their radiators are large in size, small in heat dissipation area, and low in efficiency of heat energy use. Wet materials often form agglomerates under vacuum, which causes uneven drying of wet materials and affects the drying quality of materials. At present, the failure rate of the drum drying chamber on the market is high during use. The heat dissipation pipe in the drying chamber is worn by the material during the h...

[0002] Nowadays, in the processing and production fields of grain, food, chemical industry, medicine, agricultural by-products, pasture, etc., it is necessary to heat and dry the materials under vacuum conditions; the heat exchange of the drum drying chamber of the vacuum drying equipment on the market is mostly in the form of pipes. , Interlayer heating method for heat exchange and heat dissipation, but their radiators are large in size, small in heat dissipation area, and low in efficiency of heat energy use

Wet materials often form agglomerates in a vacuum state, resulting in uneven drying of wet materials and affecting the drying quality of materials

At present, the failure rate of the drum drying chamber on the market is high during use. The heat dissipation pipe in the drying chamber is worn by the material during the heat conduction and heat exchange process. " is scrapped and cannot be used
