Powdery material dryer

Abstract

The invention discloses a powdery material dryer and a method for using the same. The feed mixing device is composed of a screw feeder, a feed hopper, a mounting plate, a stirring motor and a stirrer, and the temperature control device is composed of an air inlet temperature sensor, a power safety switch, a discharge temperature sensor and a temperature controller. , The drying device is a drying pipe, and the collecting device is composed of a discharge pipe, a collection bag and a discharge port. The invention slows down the speed of the particles in the expansion part through the action of the expansion part on the drying pipe, increases the heat around the particles, prolongs the drying time of the particles, and greatly improves the drying degree of the powdery materials; The bottom will fall to the pulverizer, and will be pulverized and then sent to the expansion part by hot air to realize secondary drying, thereby avoiding the phenomenon of agglomeration.

Description

technical field [0001] The invention relates to a dryer, in particular to a powder material dryer. Background technique [0002] A dryer is a mechanical device that uses thermal energy to reduce the moisture content of materials and is used to dry objects. The dryer vaporizes and escapes the moisture in the material (generally refers to water or other volatile liquid components) by heating 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. [0003] In various fields of processing today, the processed materials are mostly processed into powders. The powdered materials must be very dry to meet the quality standards. Therefore, the powdered materials must go through a strict drying process before the rest of the processing procedures can be carried out. Now Most of the drying devices with powdery materials adopt horizontal fluidized dryers, which include fluidized bed host, cyclone se...

AI Technical Summary

Problems solved by technology

In the existing powdery material drying device, the powdery material is continuously and uniformly moved from one end of the fluidized bed to the other end, and the drying is often incomplete or even agglomerated, which will directly affect the next process of the production line. Therefore, it must be crushed and dried again before entering the next process, which is cumbersome and inefficient.
