Granular material drying and dedusting system

Abstract

The present invention discloses a granular material drying and dedusting system, and the system comprises a rotary granule dryer and a self-cleaning filter cartridge duster; the rotary granule dryer comprises a fixed cylinder, a rotary cylinder, a motor with double shaft heads, two transmission rotating shafts, a conical air inlet cover and a discharging passageway; the self-cleaning filter cartridge duster comprises a cylindrical shell, an upper cover plate, a conical bottom, a vibration driving motor, two transmission rotating shafts, a filter assembly and a dust collecting mechanism. In thegranular material drying and dedusting system, the rotary cylinder is coaxially arranged in the fixed cylinder to form an annular heating cavity where wet materials are enabled to be fully heated anddried; two transmission rotating shafts are driven to rotate by the vibration driving motor so that a cam continuously collides with an inner wall of an upper side of an annular sleeve through rotation and a cylindrical air filter cartridge constitutes up-and-down vibration to remove internal dust; therefore, automatic cleaning and time and labour saving are achieved in the system.

Description

technical field [0001] The invention relates to a drying and dust removal system, in particular to a particle material drying and dust removal system. Background technique [0002] The rotary dryer is a widely used drying equipment. It is a rotary metal cylinder with different types of lifting plates inside. The material and hot gas pass through the cylinder and exchange heat to dry the granular material. However, spraying in the cylinder cannot reach the highest point in the center of the cylinder, so a material hole is formed in the center of the cylinder. Only hot air passes through this material hole, and this part of the hot air is directly discharged to the tail of the dryer, resulting in waste of heat energy. Dry efficiency is low. In addition, during the drying process of the rotary dryer, dust will be generated due to the tumbling of the material inside, and the dust will be blown out from the air outlet during the hot air blowing process to cause environmental pol...
