Detailed Description

A high-efficient processing slag granulator, as shown in figure 1 and figure 2, including cylinder 1, cylinder 1 both sides all are equipped with support 2, wherein install the driving motor 3 with 1 coaxial links to each other of cylinder on the support 2 of one side, still install speed reducer 4 between driving motor 3 and the cylinder 1, install the water-cooling quill shaft 5 with 1 inside looks UNICOM of cylinder on the support 2 of opposite side, water-cooling quill shaft 5 periphery is equipped with airtight cover 15, above-mentioned cylinder 1, water-cooling quill shaft 5 and airtight cover 15 can be in order to constitute totally closed mechanical structure's slag granulator, driving motor 3 can drive cylinder 1 rotatory, installs delivery pipe 6 in the water-cooling quill shaft 5, and delivery pipe 6 stretches into the one end in the cylinder 1 and installs shower nozzle 7, can spray water cooling to 1 inside.

In order to increase the strength of the steel slag granulator roller 1 and prolong the service life of the steel slag granulator roller under a high-temperature working environment, a lining plate 8 is further arranged on the inner wall of the roller 1, and a crushing medium 9 is arranged in the roller 1 on the inner side of the lining plate 8 and used for carrying out impact collision crushing on the steel slag in the roller 1. As shown in figure 3, the periphery of the roller 1 close to one end of the driving motor 3 is provided with an aggregate cover 10 communicated with the roller, the upper end of the aggregate cover 10 is provided with an exhaust port 11, the bottom end of the aggregate cover 10 is provided with a discharge port 12, a vertically arranged grate plate 13 is further arranged between the aggregate cover 10 and the roller 1, the grate plate 13 can screen steel slag with different particle sizes, so that the steel slag meeting the requirement of the particle size can be screened and enter the aggregate cover 10, and finally the steel slag is discharged by the discharge port 12 and enters the next operation procedure. Wherein the provision of the exhaust port 11 promotes further slag-iron separation.

When high-efficient processing slag granulator carry out the slag pelletization, at first high temperature slag enters into inside 1 the cylinder by water-cooling quill shaft 5, driving motor 3 starts to drive 1 rotations of cylinder, 1 pivoted in-process of cylinder, its inside broken medium 9 can mix because frictional force rotates in the lump and rises in the slag, after broken medium 9 rises to the take the altitude, again fall back to cylinder 1 bottommost slag under the action of gravity on, the circulation is reciprocal, form broken medium 9 and collide to the continuous impact of slag, in this while, shower nozzle 7 sprays the water cooling in succession, thereby realize the quick cooling and the pelletization of slag, thereby improve the effect quality of slag pelletization. The granulated steel slag can be turned over and rolled and collided in the roller 1, wherein the steel slag with the grain size meeting the requirement can pass through the grate plate 13 and enter the aggregate cover 10, the aggregate cover 10 cannot rotate along with the roller 1, and the steel slag entering the aggregate cover 10 can be finally discharged from the discharge port 12 under the action of gravity, so that the steel slag with the grain size meeting the requirement is obtained, and the rest steel slag which does not meet the requirement continues to be impacted and collided in the roller 1 until the steel slag meets the requirement.

In order to further improve the service life and the impact resistance of the roller 1, the lining plates 8 are uniformly arranged on the inner wall of the roller 1, and the thickness of the lining plates 8 is 40-50 mm. The crushing medium 9 can be the existing steel ball, the grain size of the steel ball is 6-10mm, the contact area with the steel slag is larger under the same volume, the granulation treatment effect of the steel slag can be further improved, the uniformity of the steel slag ball is better, and the steel slag ball is convenient to directly recycle.

As shown in fig. 3, the grate plate 13 is provided with a circumferential annular groove 14, the annular groove 14 has a width smaller than the particle size of the crushing medium 9, the annular groove 14 is arranged in such a way that the steel slag in a rotating state can more easily pass through the annular groove 14 to enter the aggregate cover 10 after reaching the particle size requirement, so that screening and collection are facilitated, wherein the width of the annular groove 14 is smaller than the particle size of the crushing medium 9, so that the crushing medium 9 can be ensured not to pass through the grate plate 13 and is completely positioned in the drum 1, and the granulation treatment effect of the steel slag is ensured.
