Description

A powder separator feeding device

technical field

The utility model relates to the technical field of cement processing equipment, in particular to a powder separator feeding device.

Background technique

V-type powder separator is a kind of equipment that uses air as a dispersion medium for classification, and is widely used in the screening of fly ash and cement. The existing V-shaped powder separator includes a V-shaped hollow outer casing, and the outer casing is provided with an air inlet and an air outlet. Along the direction of the wind, the outer casing is composed of a plurality of downwardly inclined steel plates corresponding to the air inlet. The air inlet grille is equipped with a plurality of upwardly inclined steel plates corresponding to the air outlet to form the air outlet grille. There is a uniform wind field between the air inlet grille and the air outlet grille, and it is also an inclined material falling area. . The top of the material rolling area has a feeding port, and the bottom has a coarse powder outlet. When the material is fed into the V-type powder separator from the feeding port, it falls on the air inlet grille and rolls down under the action of gravity. During the rolling process, it is repeatedly hit by the air inlet grille, and the cake is break up. At the same time, the air for powder selection enters the V-type powder separator from the air inlet, passes through the distribution of the air inlet grille, and flows evenly through the tumbling area of the material. Discharge the powder separator and enter the next process.

Due to the possibility of clumping and adhesion of materials, such materials will be discharged from the coarse powder due to their heavy weight after entering the V-type powder separator, resulting in a decrease in the output of fine powder, which affects the powder output.

1. The dispersing rod is driven to rotate in the feeding pipe by the driving component. When the material falls on the dispersing rod, it is smashed and scattered by the dispersing rod, so that the materials in a group are separated, and the formation between the dispersing rods is formed. The evenly arranged gaps make the passing materials more uniform, and the materials fall on the dispersing plate, so that the materials are further separated;

2. By slanting a protective plate at the feeding end of the feeding pipe, the material is blocked by the protective plate when it is scattered and splashed by the dispersing rod, so as to prevent the material from splashing outside the feeding pipe.
