Abstract

The invention relates to a vacuum type roller scraping plate drying machine. The drying machine comprises a main cylinder body. A vacuum cylinder is arranged outside the main cylinder body. The main cylinder body is arranged in the vacuum cylinder in a rotating mode. The upper end of the vacuum cylinder is provided with at least one vacuumizing opening. One end of the main cylinder body is provided with a drive rotating shaft. The other end of the main cylinder body is provided with a driven rotating shaft. The drive rotating shaft of the main cylinder body stretches out of the vacuum cylinder. Mechanical end face sealing is formed between the drive rotating shaft and the vacuum cylinder. The driven rotating shaft of the main cylinder body is supported in the vacuum cylinder in a rotating mode. A material groove is formed below the main cylinder body. A rotatable stirring shaft is arranged in the material groove. The stirring shaft is in transmission fit with the driven rotating shaft. By means of the vacuum type roller scraping plate drying machine, the vacuum degree in the vacuum cylinder is increased, gas generated due to volatilization of material liquid in the vacuum cylinder is not prone to being mixed with impurities, and therefore the purpose that the high-purity gas formed through volatilization of raw materials is collected in the vacuumizing openings is achieved.

Description

technical field [0001] The invention relates to a vacuum type drum scraper dryer. Background technique [0002] The drum dryer is a kind of internal heating conduction type rotating continuous drying equipment. The rotating drum passes through its lower trough, adhering to a certain thickness of the material film, the heat is transported to the inner wall of the drum through the pipeline, transmitted to the outer wall of the drum, and then transferred to the material film, so that the water in the material film evaporates quickly, dehumidifies, The water is discharged by the fan. The dried material is shoveled away from the drum by the scraper installed on the surface of the drum, and then the dry material is collected and packaged by the screw conveyor. [0003] In the existing vacuum drum scraper dryer, the degree of vacuum cannot reach a higher standard, and the degree of vacuum is not high, so the purity of the gas collected from the vacuum cylinder is not high, and th...
