Roller type drying structure and dryer formed by structure

Abstract

The invention discloses a roller type drying structure and a dryer formed by the structure. A first conveyor belt, a second conveyor belt, a plurality of first limiting rods, a plurality of second limiting rods, a plurality of drying cylinders, a first drive rod taken from any one of the first limiting rods and a second drive rod taken from any one of the second limiting rods are included; and thedryer also comprises a fixed bracket, a heating device, a feeding funnel, a discharging box and a scraper. According to the roller type drying structure and the dryer, through the arrangement of thefirst conveyor belt and the second conveyor belt, when materials to be dried fall onto the conveyor belts through the feeding funnel, through combined extrusion of the two conveyor belts, the materials to be dried are pressed to be of flat structures; and meanwhile, along with transmission of the conveyor belts, the materials which are to be dried and are pressed to be of the flat structures are conveyed, the materials pass through the multiple high-temperature drying cylinders in sequence, the contact area of the materials to be dried and the high-temperature environment is greatly increased,the heating and drying efficiency is greatly improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of material drying, in particular to a roller drying structure and a dryer formed by the structure. Background technique [0002] A dryer is a device for drying materials. The existing drying equipment generally puts materials into a drying container, and then heats the container to evaporate the moisture in the material to be dried through high temperature. However, in this drying method, the objects to be dried in the container are all piled up in the container in blocks, especially some fine particles of mud (such as coal slime, etc.). After forming a dense block structure, the outside of the object to be dried is easy to dry, but for the inside of the object to be dried, because it cannot quickly contact with the external high temperature environment, it is not convenient for the evaporation of internal moisture. It takes a long time to dry, which greatly affects the drying efficiency and also causes a ...

[0002] A dryer is a device for drying materials. The existing drying equipment generally puts materials into a drying container, and then heats the container to evaporate the moisture in the material to be dried through high temperature. However, in this drying method, the objects to be dried in the container are all piled up in the container in blocks, especially some fine particles of mud (such as coal slime, etc.). After forming a dense block structure, the outside of the object to be dried is easy to dry, but for the inside of the object to be dried, because it cannot quickly contact with the external high temperature environment, it is not convenient for the evaporation of internal moisture. It takes a long time to dry, which greatly affects the drying efficiency and also causes a waste of energy. Therefore, it is necessary to design a high-efficiency drying device for this type of to-be-dried objects to achieve its rapid drying. dry, save energy
