Description

Technical Field

[0001] The invention particularly relates to a ball pressing device for high-purity dolomite. Background Art

[0002] Dolomite, chemical formula: CaMg(CO3)2, is an important carbonate mineral, composed of calcium and magnesium carbonates. Dolomite briquetting refers to processing high-purity dolomite into spherical or quasi-spherical shapes for use in the reduction process of iron ore in the metallurgical industry as a reducing agent or flux. It can also be used in the chemical industry as a raw material in chemical reactions, etc. It is widely used. When high-purity dolomite powder is made into spheres, it is usually made through a briquetting machine.

[0003] When the existing high-purity dolomite powder is squeezed into a ball shape by a ball press, an inclined filter plate is generally set at the discharge port of the ball press to separate the excess dolomite powder in the ball pressing process from the formed spherical dolomite. However, the separated dolomite powder needs to be collected manually in the later stage, and then put into the ball press for further ball pressing, which is troublesome and time-consuming, with a large amount of manual labor, and is not convenient for automatic collection and processing. For this reason, we propose a ball pressing device for high-purity dolomite. Summary of the invention

[0004] The object of the present invention is to provide a ball pressing device for high-purity dolomite to solve the problems raised in the above background technology.

The outflowing dolomite balls are guided by the inclined filter plate 4, and at the same time, the excess powder on the surface of the dolomite balls falls downward through the filter groove. The fan 14 extracts the air inside the guide pipe 15 and discharges it to the outside, thereby forming a negative pressure inside the guide pipe 15, and the air is discharged through the telescopic hose 16 and the collection hole 19. The fallen powder is collected and then falls along the inclined guide pipe 15 to the inside of the screw conveyor body 6. The spiral core shaft inside the screw conveyor body 6 rotates the powder upward and re-enters the inside of the lower hopper 10 through the discharge pipe 8 for processing. The adjusting bolt 22 can be further loosened, and then the collecting block 5 and the ball press body 1 are rotated through the rotating groove 21 and the rotating rod 13, so as to better adjust the dust cover 9 to correspond to the fallen powder and better collect the dolomite powder.
