Vacuum drying equipment for synthesizing isooctyl salicylate and vacuum drying method thereof

Abstract

The invention discloses vacuum drying equipment for synthesizing isooctyl salicylate and a vacuum drying method of the vacuum drying equipment. The vacuum drying equipment comprises a U-shaped plate, a feeding pump, an oil cylinder, a vacuum pump, an elliptical box, a double-cavity round block, a spiral hole channel, an electric heating box and a peristaltic pump. The structure is reasonable, the vacuum pump continuously exhausts the interior of the oval box until the vacuum standard is achieved, the heated boiling point can be reduced, water vaporization can be accelerated, and liquid in the spiral hole channel, the inlet guide pipe and the outlet guide pipe can be circularly heated to be in a high-temperature state; a motor is operated to drive the elliptical box connected through a rotating rod to rotate, so that the effect of rolling and stirring the synthetic substances is achieved, the drying progress can be accelerated, the dried substances can enter a material pipe, and the drying efficiency is improved. And the other feeding pump used for discharging is operated to discharge the dried substances to a centralized treatment position.

Description

technical field [0001] The application relates to the field of chemical industry, in particular to a vacuum drying device for synthesizing isooctyl salicylate. Background technique [0002] Chemical industry, that is, the chemical industry. Anyone who uses chemical methods to change the composition or structure of substances or to synthesize new substances belongs to chemical production technology, that is, chemical technology.

In modern life, Chemical products are inseparable from almost anytime and anywhere, from material life such as clothing, food, housing and transportation to spiritual life such as culture, art and entertainment, they all need chemical products to serve them. [0003] In the synthesis process of isooctyl salicylate, some wet substances need to be dried, and the single-structure drying structure is easy to mix with impurities in the outside air, which affects the purity, and the drying tim...

AI Technical Summary

Problems solved by technology

[0003] In the synthesis process of isooctyl salicylate, some wet substances need to be dried, and the single-structure drying structure is easy to mix with impurities in the outside air, which affects the purity, and the drying time is relatively long, and it is inconvenient to load and unload.
