Description

Technical Field

[0001] The utility model relates to the technical field of disc dryers, and more specifically to a transmission structure of a disc dryer. Background Art

[0002] In industrial production, a drying device is required to dry wet materials. Disc dryers are common drying machines. Materials are fed into the drying equipment through the feed port. The working medium flows between the main body shell and the hollow shaft. Heat is transferred through the C-type jacket, the hollow shaft and the hollow disc welded on the shaft. The materials are indirectly heated and dried. The water vapor formed gathers on the dome of the drying equipment and is carried out of the drying equipment by the carrier gas. The hollow disc is basically perpendicular to the shaft. The material is stirred and pushed through the action of the propulsion / agitator on the disc, and the drying surface is continuously updated to achieve the purpose of drying. In addition, steam is used for indirect heating, and the material is stirred to evaporate the water faster for drying. It is suitable for both semi-drying and full-drying processes of materials. When the turntable rotates, the transmission structure is needed to transmit the driving force of the driving motor to the turntable. However, most of the existing transmission structures are exposed to the outside. When the dry material is discharged, dust is generated. The dust is easy to adhere to the transmission structure, which will cause the friction between the transmission sprocket and the transmission chain to increase, affecting the service life of the transmission structure. In addition, the transmission sprocket and the transmission chain will swing during transmission. If there is no lubricating oil on the chain surface, the friction will increase, generating a lot of heat energy and causing the chain to heat up, which will also affect the service life of the transmission structure. For this reason, we propose a disc dryer transmission structure. Utility Model Content
