Box type material dryer

Abstract

The invention provides a box type material dryer. The box type material dryer comprises a box body; a feed hopper for communicating with the internal of the box body is arranged at the top of the box body; multiple material plates are arranged in the box body in sequence from top to bottom; a driving mechanism for enabling the material plates to move up and down is arranged on the inner wall of the box body; through holes for communicating up and down are formed in the material plates; a cylinder is arranged at the bottom of the box body; the end part of an extension rod of the cylinder is connected with a pushing plate vertically arranged; a discharge port is formed in the side wall of the bottom of the box body; the cylinder drives the pushing plate to horizontally move to convey dried materials to the discharge port; an electric heating plate is arranged on the side wall of the box body; and an induced draft fan for discharging hot air in the box body is arranged at the top of the box body. The box type material dryer reduces the heat loss, and increases the heat utilization rate; and the temperatures needed by all parts of the dryer are different, so that the adjustment is facilitated, the heat efficiency is improved, and the capacity is improved.

Description

technical field [0001] The invention belongs to the field of drying equipment, in particular to a box-type material dryer. Background technique [0002] During the processing of montmorillonite or bentonite, the strips need to be dried in the dryer in the later stage of processing. The drying device will use a mesh belt dryer, but the traditional mesh belt dryer will There are many defects: First, the original mesh belt dryer usually adopts a single-layer mesh belt type, but this kind of dryer is easy to cause uneven drying, because most of the hot air is blown from bottom to top, which makes the hot air circulate , the top or inside of the montmorillonite mound may not be completely dried; secondly, the original dryer is usually equipped with a high-power natural gas burner with a combustion chamber to provide heat for the dryer, which will cause montmorillonite The drying of the soil is not thorough; again, the existing dryer will also cause the temperature of various par...
