Description

Technical Field

[0002] Fresh alumina is both the raw material for electrolytic aluminum production and the adsorbent for the purification system. Keeping the fresh alumina feed rate stable can make the harmful flue gas react more fully and improve the flue gas purification efficiency. However, fresh alumina is easy to agglomerate in the silo after accumulation. The fresh alumina feeding device currently used cannot quickly clear the agglomerated materials at the bottom of the silo. When encountering large agglomerates, the connection between the feeding device and the silo needs to be disassembled for clearing and cleaning. The process is cumbersome, the labor intensity of the workers is high, and the clearing takes a long time, which has a great impact on the flue gas purification efficiency. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is: to provide a fresh alumina feeding device which is easy to dredge, which can quickly dredge the agglomerated materials in the silo, reduce the labor intensity of workers, shorten the dredging time, and reduce the impact on the flue gas purification efficiency.

[0005] The technical solution of the utility model is to provide a fresh alumina feeding device which is easy to dredge. The alumina material in the silo is dredged and cleaned by setting a dredging pipe. There is no need to disassemble the silo connection for cleaning, thereby reducing the labor intensity of workers.

[0007] Preferably, a flip plate is provided inside the straight material discharge pipe, and the flip plate is hinged to the straight material discharge pipe; during normal material discharge, the flip plate overlaps the material feeding pipe, blocks the dredging pipe, prevents materials from entering the dredging pipe, and forms an inclined surface to prevent materials from being stranded on the flip plate during material discharge.

[0008] Furthermore, a magnet is installed on one side of the flip plate, which can be adsorbed on the side wall of the straight-through pipe for material discharge; a handle is provided on the other side of the flip plate, and a push-pull rod is hingedly connected to the handle; during normal material discharge, the push-pull rod is pulled down to pull down the flip plate adsorbed on the straight-through pipe for material discharge, and the flip plate adsorbed on the straight-through pipe for material discharge is overlapped on the material feeding pipe; when it is necessary to dredge the lumps at the bottom of the silo, the push-pull rod is pushed up to make the flip plate adsorbed on the straight-through pipe for material discharge, and then a long rod-shaped tool is extended from the dredging pipe to dredge it.

[0009] Preferably, a gate valve is installed on the material discharge straight-through pipeline, and the upper part of the gate valve is connected to the material bin; the bottom of the material delivery pipeline is connected to the screw conveyor.
