Description

The invention relates to the field of metallurgical production and is intended to remove from the buckets metallurgical production wastes in the stream (slag, cranes, burned earth).

A device is known in which slag ladles with slag and scrap are delivered to the slag yard by special railway slag carriers and are freed from slag and scrap by canting on a slag carrier with a help of the slag carrier’s canting mechanism.

The turning of the slag part is made within 115 ° towards the slag trench. In this case, frozen slag and scrap should fall out of the ladle and uncured slag should be poured out. However, practice shows that, due to the small angle of rotation of the bucket, by the canting mechanism of a slag carrier, solidified slag and scrap in the bucket hang and do not fall out, preventing the unheated slag from pouring out. In such cases, the removal of slag from the inclined slag ladle is carried out in a dangerous and imperfect way, namely: a massive load is suspended from the hook of the hoisting mechanism and, swinging it, it hits the edge of the inclined ladle on the slag truck. Under the influence of blows, slag and solidified slag crust gradually fall out of the ladle. With

In the presence of liquid melt under a crust of solid slag, the latter, breaking through the trash, in a hard crust, forms dangerous surges in the slag yard.

During blows with a swinging load on the slag ladle, serious damage is caused to the mechanisms of the slag carriage, the slag ladle itself, the railway track is destroyed, and the impact loads are perceived through the grabs of the slag carriage.

The described apparatus for the removal of metallurgical production waste (slag, scrap) from the buckets is used at most metallurgical plants.

Due to the short lifespan of the buckets and slag carriers, the problem of productive removal of slag and scrap from the buckets and the uninterrupted supply of the buckets to the metallurgical plants is relevant in ferrous metallurgy.

The purpose of the invention is to increase the degree of cleaning of the ladle from metallurgical wastes.

The proposed device is equipped with a vibrator and a drummer mounted on the beams-brackets acting on the body of the bowl. Disposal of metallurgical wastes is carried out on a separate full-pivot stand, the frame of which is equipped with vibrators and impactors (pneumatic impactors). From shock and vibration

acting on the bucket in an inverted position, the contents are completely separated from the bucket and dumped into the mu.

FIG. 1 shows the described device, front view; in fig. 2 - the same, side view.

A device for tilting and cleaning glakovoznyh buckets consists of a cast or welded frame 1, separately one hundred sh, its drive 2 rotate the frame, built into the frame of the striker 3 and the vibrator 4, pneumatic grippers 5.

The ladles entering the slag yard from the metallurgical shops with metallurgical production wastes (slag, scrap) are removed by a bridge crane from the slag carrier and are installed in the rotary frame of the device.

After the bucket is installed, the drummer and vibrator are turned on, which can work both simultaneously and separately.

At the same time, the frame drive is activated, and the bucket is rotated 180 °. To keep the bucket upside down, the frame is equipped with automatic springs or pneumatic grippers. From impacts and vibrations during the presence of the bucket in an inverted position, the frozen slag and scrap are separated from the walls of the bucket and the contents fall into the mu. After complete

cleaning the bucket it returns to its original position. The empty bucket is removed from the frame by a bridge crane and installed in a slag carrier.

The advantages of the proposed device include the following:

a) using the effect of vibration created by a vibrator (electric or pneumatic), and strikes of a certain force and frequency to remove the contents of the bucket;

b) device autonomy and the ability to rotate at any angle;

c) the ability to use to rotate the drive frame and turning mechanism

slag carriage.
