Description

Technical Field

[0001] This utility model relates to the field of material handling technology, specifically to a material drying and cooling combined equipment unloading mechanism. Background Technology

[0002] In the processing of granular materials, the raw materials retain a certain amount of moisture after mixing and granulation. Therefore, drying is necessary to prevent excessive moisture and mold growth. Existing equipment uses a separate dehumidifying fan for drying, which is energy-intensive and increases costs. The improved system connects the steam exhaust pipe to the cooling duct and includes a butterfly valve to adjust the airflow. The cooling fan simultaneously draws out the steam from the drying chamber while cooling the material, saving energy and eliminating the need for a separate dehumidifying fan. After drying, the material remains hot and requires further cooling. Conventional cooling involves natural cooling, which is time-consuming. This method of unloading involves transferring the material from the dryer to a cooling tower, typically using a screw conveyor, which requires multiple pieces of equipment and is costly.

[0015] 1. The unloading mechanism of this material drying and cooling combined equipment features electric heating tubes installed on the side of the drying chamber. Hot air is blown into the drying chamber by a hot air circulation fan, penetrating the material. Simultaneously, the air inlet of the hot air circulation fan draws in hot air from the drying chamber, forming a hot air circulation loop, which is more energy-efficient. During the heating process in the drying chamber, the material containing moisture will generate some water vapor. A water vapor exhaust pipe is also installed on the side of the drying chamber, connected to an external cooling fan, which can remove some of the water vapor. After drying, the material is discharged into a cooling tower through the unloading assembly for cooling. During the discharge process, a cyclone dust collector removes floating dust from the material.
