Problems solved by technology

Due to the large volume of hydraulic and hot-pressing equipment, they cannot be moved at will. Therefore, the scattered iron filings must be transported in bulk to the recycling company and then pressed into blocks. This mode of operation is not only inconvenient for transportation, but also labor-intensive. Large size, high recycling cost, and large space occupation; and iron filings are easily scattered on the road during transportation, seriously endangering road safety. In some areas where machining enterprises are concentrated, this problem has become a social problem that plagues the people and the government.

specific Embodiment approach 1

[0021] Such as figure 2 As shown, the device of the present invention includes a support 1 and a set of feed rollers installed in the inner cavity of the support 1 and a group of rolling and crushing groups in sequence. The A pressure roller 2, the two A pressure rollers 2 are installed at a relatively fixed distance from top to bottom, a feeding channel is formed between the two A pressure rollers 2, and a number of strips are evenly arranged on the outer surface of each A pressure roller 2 along the circumferential direction. Helical curved ribs at intervals, each curved convex rib includes several conical convex teeth 22 and several elongated convex teeth 21 with triangular cross-section arranged at intervals in sequence, and the spiral curved convex ribs on the two A pressure rollers 2 The spiral direction is opposite, the conical convex teeth 22 are mainly used to clamp and pull the iron filings into the feed channel, and the strip-shaped convex teeth 21 are mainly used ...

specific Embodiment approach 2

[0023] Such as image 3 As shown, the B pressure rollers 3 in the above-mentioned embodiment one are set up as two pairs side by side, so that the rolling channel and the crushing channel of the first rolling and crushing group and the rolling and crushing channels of the second rolling and crushing group are sequentially arranged. The connection forms the iron filings conveying and rolling channel. The iron filings are bent and rolled in forward and reverse directions for many times, so that the iron filings are completely broken and the volume is greatly reduced, which is beneficial to the feed recovery of the briquetting machine.

specific Embodiment approach 3

[0024] Such as figure 1 As shown, the device of the present invention includes a support 1 and a set of feed rollers installed in the inner cavity of the support 1 and two groups of rolling and crushing groups in sequence. To the rotating A pressure roller 2, the upper and lower distances between the two A pressure rollers 2 are relatively fixed, and a feeding channel is formed between the two A pressure rollers 2, and the outer surface of each A pressure roller 2 is uniformly arranged along the circumferential direction. A number of helical curve convex ribs at intervals, each curved convex rib includes several conical convex teeth 22 arranged at intervals in sequence and several elongated convex teeth 21 with triangular cross-sections, the spiral curves on the two A pressure rollers 2 The helical directions of the convex ribs are opposite. The conical convex teeth 22 are mainly used to clamp and send the iron filings into the feeding channel, and the long strip convex teeth ...

Abstract

A rolling and smashing method and a device thereof for scrap iron belongs to the technical field of recycle processing of the scrap iron. According to the method of the invention, by using the characteristic that the scrap iron generated by high temperature in a metal machining process has certain brittleness, the fluffy and disordered scrap iron sequentially passes by a charging channel and a rolling channel formed by radially matching a plurality of pairs of press rolls with opposite rotary directions, such that the scrap iron is bent for many times in forward and backward directions, and finally the strap iron is stretched and smashed. The device of the invention comprises a support seat and a charging roll group and at least one group of rolling and smashing group which are mounted in an inner cavity of the support seat in sequence, the charging roll group comprises a pair of A press rolls driven by transmission of a rotary driving mechanism and rotating in opposite directions, the rolling and smashing group comprises at least one pair of B press rolls driven by transmission of the rotary driving mechanism and rotating in opposite directions and a pair of C press rolls driven by transmission of the rotary driving mechanism and rotating in opposite directions, the size of the scrap iron is reduced, and the scrap iron can be directly briquetted and recycled, such that recycle machinery for briquetting the iron strap is miniaturized, and recycle cost and labor intensity are reduced.

Description

technical field [0001] The invention belongs to the technical field of iron filings recovery and disposal, and in particular relates to a method and device for rolling and crushing iron filings. Background technique [0002] Existing mechanical processing (especially turning, drilling) will produce a large number of long iron filings, and the recycling process uses hydraulic or hot pressing to pack fluffy and messy iron filings into blocks and send them back to the steel mill. Due to the large volume of hydraulic and hot-pressing equipment, they cannot be moved at will. Therefore, the scattered iron filings must be transported in bulk to the recycling company and then pressed into blocks. This mode of operation is not only inconvenient for transportation, but also labor-intensive. Large size, high recycling cost, and large space occupation; and iron filings are easily scattered on the road during transportation, seriously endangering road safety. In some areas where machinin...
