Net belt dryer with double heating plates

Abstract

The invention provides a net belt dryer with double heating plates. The net belt dryer comprises a drying chamber, a net belt conveyor, a heating device, an exhaust device, a discharge valve, a feed hopper, mixing plates and guide plates. The exhaust device is fixedly connected to an exhaust port of the drying chamber. The discharge valve is mounted on a feed port of the drying chamber. The heating device is fixedly mounted on a chamber body of the drying chamber through supports. The heating device is composed of the upper heating plate and the lower heating plate. An upper conveyor belt passes through the space between the upper heating plate and the lower heating plate of the heating device. A high-temperature heat conducting medium passes the upper heating plate and the lower heating plate to conduct conduction drying on a material on the upper conveyor belt. The heat conversion efficiency is high, and heat loss is small. The heat conduction and heat exchange speed is increased. The availability of heat energy during heat conduction and heat exchange is high. Original static stacking of the material is changed under the action of conveying inertia of the conveyor belt and guidance of the mixing plates while displacement occurs to the material, the material is turned over and move left and right within a small range, the drying efficiency of the material is improved, and thedrying effect of the material is optimized.

Description

technical field [0001] The invention relates to a mesh belt dryer, in particular to a mesh belt dryer with double-layer heating plates. Background technique [0002] The mesh belt dryer is a drying equipment for batch and continuous production. The main heating methods include electric heating, steam heating, and hot air heating. The main principle is to spread the material evenly on the mesh belt, and the mesh belt is dragged by the transmission device to move back and forth in the dryer, the hot air flows through the material, and the water vapor is discharged from the dehumidification hole to achieve drying. the goal of. The material drying of the mesh belt dryer is heated by exchanging heat outside the equipment for hot air to dry. The heat conversion efficiency is low, and the use of heat energy is one-time. The heat energy required for drying will increase a lot. There are dead corners, and the materials are easy to form agglomerates, which affects the uneven drying ...
