Description

Technical Field

[0001] The utility model relates to the technical field of powder processing, in particular to a continuous dry powder processing device. Background Art

[0002] The current main process for powder dry modification is to use a high-speed mixer or a continuous powder modifier for modification. The activation index of the powder treated in this way can only reach about 80-90%. Since a low-speed mixer can fully blend the materials, there is a practice in the existing technology of replacing the high-speed mixer with a low-speed mixer. However, to achieve low-speed mixing and continuous modification, a set of dry modification equipment is required.

[0003] Its application number "202221872017.2" discloses a "continuous powder modifier with pre-heating and mixing function", which "includes a powder modifier and a mixing heating barrel connected to the powder modifier through a screw conveyor, a horizontal plate and a cover body hingedly connected to the horizontal plate are fixed on the top of the mixing heating barrel, a reduction motor is provided on the horizontal plate, the output end of the reduction motor extends into the mixing heating barrel and is connected to a stirring device, a pipe connected to the screw conveyor is provided at the bottom of the mixing heating barrel, a valve is plugged on the pipe, and a PLC controller is provided on the side wall of the mixing heating barrel, and the PLC controller is electrically connected to the powder modifier, the mixing heating barrel, the screw conveyor and the reduction motor respectively. "In the utility model, the mixing heating barrel can quickly heat the powder to be processed; the reduction motor and the stirring device cooperate to quickly stir the powder so that the modifier is evenly bonded to the powder; the screw conveyor can transport the processed powder to the powder modifier for processing.

[0004] However, the above method still has the following defects: the powder and modifier to be processed can be added to the mixing and heating barrel by opening the cover, but it is not convenient for quantitative loading, and the cover needs to be closed during the heating process, which makes it difficult to ensure continuous loading of the powder and the modifier. The processed powder can enter the screw conveyor through the pipeline and the valve, but the friction between the powders is large, and it is easy to accumulate in the pipeline, which will cause blockage of the pipeline.
