SU60365A1 - A device for unloading lime from a kiln with a conveyor - Google Patents

Description

In order to increase the productivity of coal lime kilns, it is advisable to introduce in them the lower air blowing. However, in common non-mechanized kiln dumping furnaces, the use of blowing air is made difficult by the fact that the discharge grate and ashpit are usually open under them, which makes it impossible to keep the pressure in the mine.

Usually, lime is discharged in non-mechanized furnaces by manually moving apart individual grates and a layer of lime between them by a shurov, the lime falls on the ash pit floor and from there it is manually poured into the trolley.

It has already been proposed to periodically unload the cooled material with belt conveyors located under the furnace.

The proposed device also uses a conveyor belt. w, under the stove, but in order to be able to apply artificial air blast and germize unloading, the lower part of the stove, which is shaped like a bunker, and the receiving head of the trans. The sportsman is enclosed in a metal casing, tightly attached to the walls of the bunker and the floor, and from the side. A material box with curtains has been applied to release the material on the conveyor.

FIG. 1 is given a vertical section through a lime kiln shaft furnace with the proposed device for unloading lime, in section along AA, FIG. 2; in fig. 2-section. BB; FIG. one; in fig. 3 is a plan view in section along explosives of FIG. one.

The number / marked furnace shaft, 2-discharge grate.

Bunker 3, quiescent w, iy on embedded I-beams 4, is fitted in its upper part with folding aprons 5 - 5 and is covered with a metal casing 6 in the form of a box, one hundred sh, on the ash pan floor. The casing 6 fits snugly to the walls of the hopper 3, forming it. lower part of the furnace. The hopper 3 and the receiving head of the tape conveyor. The spider 7 is enclosed in the casing 6, which is well sealed from all sides except the opening that allows the transparter 7 to pass through.

To seal and that from. version, it is closed by a series of hanging cloth gastight. 8 curtains with stitched weights sliding along the lime moving and reduced on the belt

thus, air loss through the opening. The reverse branch of the conveyor belt 7 passes M € waiting for two rollers 9, and the gap between the rollers is tightly closed by a wall 10.

The release of lime from the hopper 3 to the conveyor belt is regulated by more or less pushing the pins 11 into the hopper. The conveyor belt 7 can be made mobile.

Opening one or another folding apron 5, you can make shurov. ku and scraping pieces of lime into the bunker. At the end of the unloading, the apron is hermetically sealed again and pressed against it with the butterfly wings available for this.

The use of air blowing. Together with the proposed device

FIG. one

and a bunker, they increase the productivity of the furnace, speed up the loading of lime into the wagons or the spare warehouse, and at the same time save workers from heavy physical labor and unhygienic working conditions.

The subject of the invention is a device for unloading lime from a kiln with a conveyor located under the furnace, characterized in that, in order to seal the unloading, the bottom. The furnace part in the form of a bunker and the receiving head of the conveyor are enclosed in a metal casing tightly adjacent to the walls of the bun. kera and to the floor, and from the material release side, a box with curtains was applied to the conveyor.
