Working principle of the dryer
Power is generated by electricity, diesel, wind, flammable materials, etc., and the ambient air is heated and transported to the surrounding area to reach the appropriate temperature for dehumidification.
The specific process is as follows: the wet material is sent to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe through the feeding machine of the hopper. The inclination of the feeding pipe should be greater than the natural inclination of the materials so that the materials can flow into the dryer smoothly. The dryer cylinder is a rotating cylinder, which is slightly inclined with the horizontal line. Materials are added to the heat carrier from the higher end, and the heat carrier enters from the lower end to make counter-flow contact with the materials. Sometimes the heat carrier and materials flow into the cylinder together. As the cylinder rotates, the materials move to the lower end due to gravity. When the wet materials move forward in the barrel, they directly or indirectly receive the heat from the heat carrier, so that the wet materials dry, and then are sent out through the discharge end through a belt conveyor or screw conveyor. The inner wall of the barrel is equipped with a lifting flight. Its function is to lift the materials and scatter them, to increase the contact surface of the materials and the airflow, in order to improve the drying rate and promote the advancement of the materials. Heat carriers are generally divided into hot air, flue gas, etc. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to capture the materials carried in the gas. Dryer Features
High drying intensity. Since the material is highly dispersed in the air flow, the entire surface of the particles is actively used as an effective area for drying.
Short drying time.
The airflow dryer has a simple structure, a small footprint and is easy to construct and maintain.
Large processing capacity and high thermal efficiency. Thermal efficiency is achieved when drying unbound water.
The dryer achieves zero horizontal thrust, which greatly reduces the wear of the supporting wheel. The cylinder operates smoothly and reliably
The dryer adopts an aligning supporting wheel device so that the cooperation between the supporting wheel and the rolling ring is always in linear contact. Wear and power loss are greatly reduced.
