[0002] The drum dryer is one of the traditional drying equipment. It is mainly composed of a rotating body, a lifting plate, a transmission device, a supporting device and a sealing ring. The dryer is a cylinder slightly inclined to the horizontal direction. The material is added from the higher end. The high-temperature hot flue gas generated by the heating equipment flows into the cylinder with the material. As the cylinder rotates, the material moves to the lower end due to gravity. A lifting plate is installed on the inner wall of the cylinder to lift the material and sprinkle it down, so that the contact surface between the material and the airflow is increased to increase the drying rate and promote the forward movement of the material.

[0003] However, the traditional drum drying equipment has a large air intake volume during use, which may lead to an increase in dust during the operation of the drum, and thus easily cause a certain impact on the surrounding environment and the breathing environment of the surrounding workers. For this reason, the utility model proposes an external heating drum structure to solve the above problem. Utility Model Content
