Description

one

A known electro-vibrating rammer is used to pack a refractory mass of a blast furnace chute, comprising a housing, a slab and an electric vibrator, the shaft of which is located along the chute. The rdiako such a tamper cannot independently move along the gutter. This complicates the use of a tramboak, requires a lot of time to do mine mining operations, and necessitates an additional truck to move the ramming along the trough. In addition, the specified location of the shaft of the vibrator nrnvodnt to frequent lateral tilting of the rammer.

The difference with the proposed electrovibro tamper is that in order to improve its service conditions, it is equipped with a second electric vibrator, both vibrators being made by two rollers and mounted on a plate so that their shafts are 1pp11 perpendicular to the longitudinal axis of the body. The direction of the resultant (perturbing) force created by the operation of each of the vibrators, forms with the vertical to the base of the vibrator an angle greater than the angle of inclination of the groove to the horizon.

FIG. 1 shows the described electric vibrotraction; in fig. 2 - the same, cross section; in fig. 3 - installation of tamper li is desirable for the scheme of action of si, -1 in its operation.

The tamper consists of a body L of a nlit 2 rigidly connected to it and placed on the inclined platforms of a plate of two two-two electrovibrators 3. An external transverse GFRfil of the body assembled with a plate repeats

profile of the gory gutter.

In order to fix the trough with a refractory mass of electrolibro rammer by means of the bridge specks of the foundry yard, they are installed in the tail part of the groove (see Fig. 3), including the right vibrator, and tamping, producing a groove of the chute, one element under the influence of the resultant (disturbing) force right in the direction of the cast-iron kids.

After reaching tamper extreme

right position, turn off the right vibrator and turn on the left vibrator. The rammer, the itepoiiHOCTH grab on the surface of the refractory mass layer, moves in the opposite direction along the chute. As needed

packing operations are repeated. At the end of these operations, the tamper is transported by a bridge crane to the storage site.

Subject invention

Electro-vibrating rammer for filling a blast chute with a refractory mass containing a body, a plate and an electric vibrator, characterized in that, in order to improve the conditions of its service, it is equipped with a second vibrator 34 with an electric vibrator, and the two are mounted on the plate with their shafts arranged double-shaft and perpendicular to the longitudinal axis of the housing. 373301
