Abstract

The utility model relates to an utilize wind-force to make device of iron fillings and incomplete sand separation, the size iron residue after utilizing the clearance is different with their proportion of old sand, adopts invariable directional wind-force to blow to the iron sand mixture, and the mixture is according to the difference of proportion itself, and the position that falls down is also diverse, falls into different separation boxes from nearly to far respectively to reach the purpose of sorting.

Description

Device for separating iron chips from residual sand by utilizing wind power

Technical Field

The casting equipment can separate the residual scrap iron in the casting industrial casting unpacking residual sand.

Background

The casting is cooled and cleaned by a shakeout roller after being poured, the separated residual iron and residual sand are separated by using a screening method in sand treatment, large residual iron or sand lumps are separated by using a screening method, the screen holes have about 10mm of pores, but small residual iron is mixed in old sand, the small residual iron deteriorates the surface of the casting mould if being subjected to re-molding in a sand regeneration link, the existing air holes can pass through the small sand lumps, but small scrap iron cannot be separated, the leaked screen holes enter the old sand, and the screen holes cannot be further separated.

SUMMERY OF THE UTILITY MODEL

The iron filings are separated from the used sand by utilizing the specific gravity difference between the iron element and the used sand and adopting wind power separation.

The technical scheme is that a screened iron sand mixture is conveyed to the upper part of an air port through a vibrating conveying bed, falls in a loose state, is transversely blown by certain wind power, has different falling positions due to blowing when falling with high specific gravity and light specific gravity, is provided with falling bins according to different specific gravity sizes at the lower part according to the distance of a falling point, and is connected with a bag-type dust collector at a terminal to capture dust formed by final fine sand particles without flying to the external environment.

The utility model discloses a show the effect that the used sand is purer, and iron fillings also can further recycle, not only improve quality to the casting surface, also make the iron element throw the stove volume simultaneously and reduce cost proportion.

Drawings

FIG. 1 is a schematic view of an air sorting apparatus.

Wherein, 1, a shakeout roller machine 2, a vibration conveying bed 3, a blower 4, a wind power sorting channel 5, a sorting box 6 and a bag-type dust remover

Detailed Description

The used sand and residual iron mixture flowing out of the screen cylinder of the shakeout roller 1 falls onto the vibration conveying bed 2, the used sand flow which is uniformly and slowly formed by the vibration bed 2 falls into the wind power separation channel 4, the blower 3 blows the used sand flow at constant wind power and wind speed, the used sand flow respectively falls into the separation boxes 5 at different positions according to specific gravity, smaller particle dust is captured by the bag-type dust collector 6 and filtered into the ash box, and purified air is discharged into high-altitude atmosphere.

Claims

1. The utility model provides an utilize wind-force to make device of iron fillings and incomplete sand separation which characterized in that: the mixture passing through the shakeout roller screen cylinder is conveyed to the upper part of the air port through the lower vibrating conveying bed and falls in a loose shape, constant transverse wind force blows the lower part of the shakeout roller screen cylinder, so that scrap iron and residual sand with different specific gravities fall to the sorting boxes at different positions from heavy to light according to different specific gravities, and the terminal is connected with a bag-type dust collector to capture and purify dust and then enter the atmosphere.
