Environment-friendly type rotating drying system

Abstract

The invention discloses an environment-friendly type rotating drying system. The environment-friendly type rotating drying system comprises a rotating barrel type dryer and a self-clearing type filterelement dust remover; the rotating barrel type dryer comprises a fixed cylinder, a rotating roller, a double-shaft-head driving motor, two driving rotating shafts, an air inflow conical cover and a material outflow channel; and the self-clearing type filter element dust remover comprises a cylindrical shell, an upper cover plate, a conical bottom, a vibrating driving motor, two transmission rotating shafts, a filtering assembly and a dust collecting mechanism. According to the environment-friendly type rotating drying system, the rotating roller is coaxially arranged in the fixed cylinder, and therefore an annular heating cavity is formed, so that wet materials are fully heated and dried in the annular heating cavity; the vibrating driving motor is used for driving the two transmission rotating shafts to rotate, so that a cam rotates and ceaselessly collides with the inner wall of the upper side of a ring sleeve, and therefore a cylindrical air filter element is vibrated up and down,internal dust is vibrated down, automatic clearing is achieved, and time and labor are saved.

Description

technical field [0001] The invention relates to a drying system, especially an environment-friendly rotary drying 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 material. It is characterized by good adaptability to materials, and can dry a variety of materials with different moisture, particle size (block, granular, powder) and viscosity. 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 ...

Problems solved by technology

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. low drying efficiency

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, causing environmental pollution
