Particle drying machine

Abstract

The invention provides a particle drying machine. The particle drying machine comprises a box and a support, wherein the box is supported on the support. The particle drying machine further comprises a stirring shaft, a feed passage and a discharge passage. The stirring shaft penetrates through the interior of the box and is fixedly connected with a motor. The motor is fixed to the support. A valve for controlling the airflow rate is arranged on the portion, above the box, of the stirring shaft. The valve is fixedly connected with a hot air supply system. A plurality of stirring paddles arranged at intervals and an air hole set are arranged on the portion, inside the box, of the stirring shaft. Each stirring paddle is in a cone shape. The radii of the bottoms of the stirring paddles increase sequentially from top to bottom. The feed passage is fixed to the top of the box. The discharge passage is arranged at the junction between the bottom of the box and the side face of the box. The top of the box is provided with an air outlet. The particle drying machine has the advantages of being capable of fully drying light and hard particles, short in drying time, high in drying efficiency, little in particle loss and convenient to popularize and use.

Description

Technical field [0001] The invention relates to a dryer, in particular to a particle dryer. Background technique [0002] Dryer is a kind of mechanical equipment that uses heat energy to reduce the moisture content of the materials. It vaporizes and escapes the moisture or other volatile liquid components in the materials through the addition of heat sources to obtain solid materials with specified moisture content. The need for use or further processing. The traditional dryers used to dry solid particles mostly remove the wet components in the particles by heating and continuous stirring after passing the materials. The effect is good for particles with larger surface hardness; but for light, light and hard particles As for the particles, it is very easy for the repeated friction between the particles and the friction between the particles and the stirring device during the stirring process to cause excessive loss. Therefore, it is necessary to propose a new technical solution ...

AI Technical Summary

Problems solved by technology

Most of the traditional dryers for drying solid granules remove the moisture content in the granules by heating and stirring continuously after feeding the materials. It works well for granules with high surface hardness; but for light and hard granules For the particles, it is very easy to repeat the friction between the particles and the friction between the particles and the stirring device during the stirring process, and the loss is too large. Therefore, it is necessary to propose a new technical solution to solve the above problems.
