Problems solved by technology

refer to figure 1 , when the material lifting plates of these two structures are lifting materials, because each panel is a rectangular structure, and under the action of material gravity, the material throwing position is concentrated, so it is difficult to form a connected material curtain, resulting in Large-area voids, small contact area between materials and heating air flow, resulting in low drying efficiency and high energy consumption, which cannot meet the requirements of energy saving and emission reduction

Abstract

The invention provides a drying drum. The drying drum comprises a drum body. The drum body is provided with a feed inlet and a discharge outlet which are arranged opposite to each other. The inner wall face of the drum body is fixedly provided with a material lifting plate, the feed port of the material lifting plate faces towards the feed inlet of the drum body, the discharge port of the material lifting plate faces towards the discharge outlet of the drum body, the material lifting plate is of a gradually-expanding structure in the axial direction of the drum body, and the size of the cross section of the discharge port of the material lifting plate is larger than the size of the cross section of the feed port of the material lifting plate, so that the total extending length of the discharge end of the material lifting plate is larger than that of the feed end of the material lifting plate, the spraying width of materials at the discharge end of the material lifting plate is increased, the materials sprayed out of the cross section of the drying drum form waterfall continuous materials curtains easily, the area of cavities in the cross section of the drying drum is reduced, the contact heat exchange area between the materials and hot airflow is increased, then the heat efficiency of the dryer is improved, and the purpose of energy conservation and emission reduction is achieved.

Description

technical field [0001] The invention relates to material drying equipment, in particular to a drying drum and a dryer with the same. Background technique [0002] In the production of building materials industry, the raw materials, fuels and mixtures used all contain a certain amount of moisture. Dry them to reduce the moisture content to meet the moisture requirements of materials for calculation, transportation and homogenization. It is also conducive to ensuring product quality and improving the system. normal operating rate. At present, the commonly used drying equipment is a drum rotary dryer. This dryer can be used in dry-mixed mortar drying system for drying solid materials. [0003] Existing dryers include a drying drum and related driving devices, etc., wherein the drying drum includes a cylinder and a lifting plate arranged in the cylinder. When working, the cylinder rotates under the drive of the driving device, and the cylinder in the cylinder rotates. The mat...
