Drying device for aluminum hydroxide micro powder

Abstract

The invention discloses a drying device for aluminum hydroxide micro powder, and relates to the technical field of aluminum hydroxide micro powder drying. The drying device comprises a device main body, a feeding mechanism is mounted at the top end of the device main body, a primary drying assembly and a secondary drying assembly are mounted in the device main body, circulating ventilation assemblies are mounted on the two sides of the device main body, the primary drying assembly comprises a bracket fixedly installed on the inner wall, close to the top end, of the device body, and the inner side of the bracket is rotationally connected with a material drying disc through a bearing. An arranged air outlet ring pipe is matched with the arranged material drying disc, so that aluminum hydroxide micro-powder can be primarily dried; and by means of a material drying vortex cylinder, hot air can carry a material to be blown into the material drying vortex cylinder, the material can make full contact with the inner wall of the material drying vortex cylinder in cooperation with the multiple spiral wall grooves, and further drying treatment on the material is achieved in cooperation with the heating effect of heating arc wires.

Description

technical field [0001] The invention relates to the technical field of aluminum hydroxide micropowder drying, in particular to a drying device for aluminum hydroxide micropowder. Background technique [0002] Aluminum hydroxide is an inorganic substance with the chemical formula Al(OH) 3 , is the hydroxide of aluminum. Aluminum hydroxide can not only react with acid to generate salt and water, but also react with strong base to generate salt and water. It has many functions: it can be used as a catalyst, and of course it can also be used as a catalyst carrier; it needs to be dried during the manufacture of aluminum hydroxide micropowder. [0003] The Chinese utility model patent whose publication number is CN210980645U discloses a drying device for aluminum hydroxide micropowder, including a device body, the upper end of the device body is fixedly connected with a drive mechanism, and the lower end of the drive mechanism extends into the body of the device. The inside is ...

Problems solved by technology

[0004] However, the above-mentioned invention has the following disadvantages: when the above-mentioned device feeds, it is directly transported to the inside of the device body through the feed port, and when the aluminum hydroxide material agglomerates, it will seriously affect the subsequent drying effect; on the other hand , the surrounding design of the heating coil, although there is a stirring design in the main body of the device, the contact with the material inside the main body of the device is still not sufficient, resulting in low drying efficiency, so there are certain limitations
