Abstract

A double-helix feeder comprises a support, a bin, a screw propeller, a lower drive shaft part, an upper drive shaft part, a reduction box and an adjustable-speed motor, wherein the outlet of the bin corresponds to the screw propeller, the blade at a central position of the bin is driven by a rotary compression shaft part, the connection and transmission of the rotary compression shaft part and the lower drive shaft part are realized through a bevel gear group, and the lower drive shaft part is locked by a bolt; the screw propeller is in butt joint with the upper drive shaft part through a double slider coupling, and the upper drive shaft part is connected with the lower drive shaft part through a belt wheel; and the upper drive shaft part is connected with the reduction box through a cross-linked coupling, and the reduction box is connected with the adjustable-speed motor through a V-belt and the belt wheel. By the double-helix feeder provided by the invention, a drying machine can be enabled to better convey and feed viscous materials, so no stagnation and adhesion phenomena are generated, and the material loosening efficiency and stability are ensured.

Description

technical field [0001] The invention relates to a double-screw feeder, which belongs to the feeding device in the field of dryer equipment. Background technique [0002] Steam dryers are widely used in pesticides, dyes, pigments, fine chemicals, feed, additives and other industries for recognition and promotion. Pine existing airflow desiccant, especially the rotary airflow dryer, because the rotary flash dryer handles mostly filter cake-like materials, it needs to be fed by a screw feeder. If the material to be dried is non-sticky, granular or lumpy, it can be fed by ordinary conveyor belts, but when it comes to some sticky materials, ordinary feeding devices cannot meet the requirements. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the problem that the existing drying machine cannot realize the feeding of viscous materials by adopting the conveyor belt, and provides a double-screw feeder. [0004] In order to sol...
