Abstract

The invention relates to the field of evaporator equipment. The invention further discloses a scraper type film evaporator comprising a heating casing pipe, an evaporation casing pipe, a secondary treatment box, a transmission shaft and a distributing device, wherein the evaporation casing pipe is arranged in the heating casing pipe, the secondary treatment box is arranged at the top of the heating casing pipe, a rotatable transmission shaft is arranged in the middle of an inner cavity of the evaporation casing pipe of the heating casing pipe, and the top end of the transmission shaft is fixedly sleeved with a rotary joint located above the secondary treatment box. According to the scraper type film evaporator, the transmission shaft, a stirring mechanism, a fixed through pipe, a sealing plug, a linkage shaft, a stirring shaft and a flow guide mechanism are designed; during use, evaporated dry steam is sprayed out obliquely upwards from the bottom of the evaporation casing pipe, so that the down-flow rate of materials is reduced to a certain extent, the evaporation effect of the materials is improved, meanwhile, the dry steam heats the materials on the inner side, the heating effect is further improved, and sufficient heating of the materials is facilitated.

Description

technical field [0001] The invention relates to the field of evaporator equipment, in particular to a scraper type thin film evaporator. Background technique [0002] The scraper thin film evaporator is a kind of efficient evaporation and distillation equipment that uses high-speed rotation to distribute the liquid into a uniform film for evaporation or distillation. It can also perform unit operations such as deodorization, defoaming reaction, heating, and cooling. The scraper thin film evaporator is widely used. It is suitable for Chinese and western medicine, food, light industry, petroleum, chemical industry, environmental protection and other industries. [0003] The working principle of the existing scraped film evaporator is as follows (refer to Figure 4-5 ): by adding a heat source into the chamber between the heating sleeve 1 and the evaporation sleeve 2, the inner wall of the evaporation sleeve 2 is heated up, and the material is added from the feeding pipe at the...
