Feeding pipe preheating device of molecular distillation equipment

Abstract

The invention discloses a feeding pipe preheating device of molecular distillation equipment, and belongs to the technical field of molecular distillation equipment. A shaft sleeve on one side wall ofan upper fixing plate is connected with a shaft sleeve on one side wall of a lower fixing plate through a shaft pin; the lower fixing plate is arranged on the lower side of the upper fixing plate; the upper fixing plate and the lower fixing plate are both set to be a semi-cylindrical shape; the upper fixing plate and the lower fixing plate are spliced into a cylinder; a first connecting piece isfixed to the other side wall of the upper fixing plate; the first connecting piece is fixed to a second connecting piece through a bolt; the second connecting piece is fixed to the other side wall ofthe lower fixing plate; a plurality of preheating mechanisms are arranged between the lower fixing plate and the upper fixing plate at equal angles; and a supporting mechanism is arranged on the lowerside of the lower fixing plate; when a feeding pipe is connected with a heavy component buffer tank and the molecular distillation equipment, the feeding pipe is wrapped by part of heat in the heavycomponent buffer tank, so that the preheating effect on the feeding pipe is achieved. The feeding pipe preheating device has the advantages of reasonable arrangement, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of molecular distillation equipment, in particular to a feed pipe preheating device for molecular distillation equipment. Background technique [0002] Molecular distillation is also called short-path distillation. A complete set of molecular distillation equipment mainly includes: molecular evaporator, degassing system, feeding system, heating system, cooling vacuum system and control system, etc. In specific applications, molecular distillation equipment is used For connecting the feed pipe and the heavy component buffer tank, in order to save energy and recycle heat energy, there is a structure in the prior art that can collect the heat of the heavy component buffer tank through a heat transfer medium, and use this heat to preheat the feed pipe In this structure, the heavy component buffer tank is connected to the two ends of the feed pipe with the preheating chamber respectively through two pipelines, an...

[0002] Molecular distillation is also called short-path distillation. A complete set of molecular distillation equipment mainly includes: molecular evaporator, degassing system, feeding system, heating system, cooling vacuum system and control system, etc. In specific applications, molecular distillation equipment is used For connecting the feed pipe and the heavy component buffer tank, in order to save energy and recycle heat energy, there is a structure in the prior art that can collect the heat of the heavy component buffer tank through a heat transfer medium, and use this heat to preheat the feed pipe In this structure, the heavy component buffer tank is connected to both ends of the feed pipe with a preheating chamber through two pipelines, and the collected heat is easily lost in the pipeline, especially when the distance between the heavy component buffer tank and the molecular distillation equipment is far away state, the warm-up effect is negligible
