Stirring vacuum drying machine of scraping plate

Abstract

The invention relates to a stirring vacuum drying machine of a scraping plate. The stirring vacuum drying machine comprises an upright cylinder, a stirring device, an evacuating device and a heating device, wherein the upright cylinder is of a separated structure and comprises a cylinder body and a cylinder cover, wherein the cylinder body is provided with a closed end, an opened end and a side wall; a material outlet is formed in the place, close to the side wall, on the closed end; the cylinder cover covers the opened end; a material inlet and an evacuating opening are formed in the cylinder cover; the stirring device is formed by sequentially connecting a driving mechanism, a main shaft, a stirring frame and the scraping plate; the main shaft penetrates through the cylinder cover to extend into the cylinder body; the stirring frame is arranged at the lower end of the main shaft; the scraping plate is arranged at the lower end of the stirring frame; the evacuating device is arranged at the evacuating opening; the heating device wraps the cylinder body. According to the stirring vacuum drying machine, due to the fact that the material outlet is directly formed in the closed end of the cylinder body and is close to the side wall, the scraping plate just pushes dried materials to the place, close to the side wall, of the closed end, and the materials move along the scraping plate, the materials are very easily pushed out of the material outlet, and the stirring vacuum drying machine is simple, feasible and quick in operation; due to the fact that the materials are not stuck to the inside of the cylinder body, the materials are completely discharged.

Description

technical field [0001] The invention relates to a drying device, in particular to a scraper stirring vacuum dryer. Background technique [0002] At present, disc dryers and vacuum rake dryers are drying equipment widely used in the pharmaceutical, chemical, pesticide, and food industries. Disk dryers are generally used to dry granules and less viscous materials, but they are not suitable for drying paste materials; while rake dryers can dry paste materials, but the output is not clean. Continuous production will affect the quality of the next batch of materials, and will also reduce the original drying efficiency, and the structure is complex, the volume is large, the overall drying heat transfer rate is relatively low, and the production cost is high, so the above drying equipment has become more and more popular. Can not meet the needs of the market. [0003] Although the existing vertical stirring vacuum dryer can dry the viscous material, it is inconvenient and unclean...
