Pulsation vacuum rotary drier

Abstract

The invention discloses a pulsation vacuum rotary drier which comprises a rotary drying barrel. The bottom of the rotary drying barrel is connected to a rotary driving mechanism for driving the rotarydrying barrel to rotate. A pulsation air flow generator for generating pulsation high-temperature dried hot air is mounted at the top end in the rotary drying barrel, and the top of the rotary dryingbarrel is also connected to a vacuum pump valve bank for realizing a vacuum environment. A vacuum environment is formed in the rotary drying barrel by means of a vacuum pump, so that the temperatureneeded for heating and drying is further reduced, and therefore, the energy is saved and the consumption is reduced. A rotary driving motor in a rotary driving mechanism drives a roller and a rotary stirring rod through a reducer and a rotary joint, separately to meet the demands on rotary drying operations in different environments, so that a material is heated more uniformly. High-temperature gas is generated by heating of a high-temperature electric heating pipe, pressurization and acceleration are carried out by a centrifugal fan, and pulsation air flows adjustable in frequency and size are output by combining the blade type pulsation generator, so that the drying efficiency is improved greatly.

Description

technical field [0001] The invention relates to the field of material drying equipment, in particular to a pulsating vacuum rotary dryer. Background technique [0002] In the manufacturing of power equipment and distribution network-related equipment, commonly used equipment is dryers, such as plastic material processing for cable skins. [0003] Dryer refers to a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The dryer vaporizes and escapes the moisture (generally referring to water or other volatile liquid components) in materials by heating, so as to Obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. According to the operating pressure, the dryer is divided into two types: normal pressure dryer and vacuum dryer. According to the operating pressure, it can be divided into normal pressure and reduced pressure (also know...

AI Technical Summary

Problems solved by technology

[0005] Although the existing vacuum dryer can achieve hot air drying, it cannot conveniently stir the material, the material is heated unevenly, and the drying speed is slow; its heating system does not have an automatic adjustment function, and the pulsation frequency and amplitude of the pulsating airflow output can be adjusted inconvenient
