Abstract

The invention discloses a vacuum drum drying device. The vacuum drum drying device comprises a cooling barrel, a dust removing barrel and a heating jacket; one side of the lower end of the cooling barrel is connected with a vacuum pump; the cooling barrel and the dust removing barrel are connected through a pipe; a pressure pump is arranged between the dust removing barrel and the heating jacket; the upper end of the pressure pump is connected with a nitrogen inlet; the upper end of the heating jacket is provided with a material inlet / outlet; a sampling port is formed in the lower end of the heating jacket; and a steam inlet and a condensate water outlet are formed in one side of the heating jacket. The vacuum drum drying device can realize large-scale and continuous production, is short in drying time, high in production capacity, simple in structure and low in production cost, and can be applied to batch and multi-species production of several special fibers.

Description

technical field [0001] The invention relates to the field of chemical production, in particular to a vacuum drum drying device used in the field of chemical production. Background technique [0002] Vacuum drum dryer is a commonly used equipment in chemical production enterprises. Its function is to dry raw materials. The working principle of vacuum drum dryer is to evaporate the water in the slices at a certain temperature, and then use the vacuum system to remove the water with the help of the vacuum system. The air is extracted together to achieve the purpose of drying the slices. The process is shown in the figure below, mainly divided into three parts: wet slice conveying, vacuum drum drying and dry slice conveying. Wet slices are sifted through a screening machine to remove powder and cutting materials, and after metering, fall into a vacuum drum for drying at elevated temperatures. The dried slices are cooled before leaving the drum, and then nitrogen or dehumidifie...
