Active drying tower system

Abstract

The invention relates to an active drying tower system, belonging to the technical field of material drying. The invention is characterized by consisting of plural layers of drying discs, feeding ports, dodge gate mechanisms, stirring shafts, a motor driving device, a stirring device, circular wind outlet and inlet ports, a circular wind pipeline, a circular drying wind device, a drying cold winddevice, a material inlet and a material outlet; plural layers of drying discs with pores are fixed at equal intervals in the tower body sequentially, each feeding port is arranged on each layer of drying disc, the feeding ports are arranged in a stagger way, each feeding port is provided with each dodge gate mechanism penetrating through stirring shafts at the center of each layer of drying disc from the bottom of the tower, the motor driving device is arranged at the bottom of the tower and meshed with the bottom end of the stirring shaft, the stirring device is fixed on the stirring shaft corresponding to each layer of drying disc, the interphase drying discs on the upper side and the lower side of the tower body are provided with the circular wind outlet and inlet ports from top to bottom, all the circular wind outlet and inlet ports are connected to the circular wind pipeline, the circular wind pipeline is internally connected with the circular drying wind device of 78-82 DEG C, the drying cold wind device is connected to the drying disc of the lowest layer in the tower from bottom, the material inlet is arranged at the top of the tower body and the material outlet is arrangedat the bottom of the tower body; and the invention is favorable for reducing quantity of power consumption and steam consumption, is adaptive to mass production, is applicable for drying materials with high thermal sensitivity, and has stronger practicability.

Description

technical field [0001] The invention relates to an active drying tower system, which is suitable for drying materials with high heat sensitivity and belongs to the technical field of material drying. Background technique [0002] At present, there are many domestic drying equipments, such as tube bundle dryers, drum dryers, airflow dryers, fluidized bed dryers, etc. each have their own advantages and disadvantages. The tube bundle dryer is mainly suitable for loose materials with low heat sensitivity and low viscosity. It occupies a small area, has a large evaporation of dry water, and saves steam. The drum dryer is suitable for loose materials with high viscosity, which has low output, low power consumption, and large steam consumption; the airflow dryer and fluidized bed dryer are suitable for materials with high heat sensitivity, which have low output, high power consumption, and high steam consumption. large.

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an active drying tower system to solve the problems of low drying output, large power consumption, and high energy consumption of existing airflow dryers and fluidized bed dryers used for drying materials with high heat sensitivity due to their structural factors. Due to the disadvantage of large steam volume, the invention realizes high drying output, reduces power consumption and steam consumption, adapts to large-scale production, and is suitable for drying materials with high heat sensitivity
