RU2831380C1 - Umbrella for uniform distribution of discharged coke into coke car - Google Patents

Abstract

FIELD: coke industry.

SUBSTANCE: invention relates to coke-chemical industry, in particular, to an umbrella for uniform distribution of discharged coke into a coke car. Umbrella is included into the installation of dust-free output of coke from the coke furnace, which contains a door-removing machine, to which the umbrella is fixed, a coke car. At that, umbrella is equipped with two distributing devices for uniform distribution of coke output, located in umbrella offset in its extreme parts, in axis of coke car tracks, each distributing device comprises a shaft with a blade, installed vertically, with possibility of reciprocating turns by 30°-70° by means of crank mechanism drive or umbrella is equipped with one distributing device installed in axis of umbrella in vertical plane relative to coke furnace, from which coke is unloaded into coke car.

EFFECT: uniform distribution of discharged coke from coke furnace into coke-carrying car, exclusion of accumulation in car body of discharged coke from coke furnace, beyond their dimensions on height and increase of efficiency of safety of operation of dust-free discharge of coke from coke battery.

Description

The invention relates to the coke industry, in particular to methods and devices for removing dust and gas products formed during the delivery of coke from coke ovens to a moving coke quenching car or coke car.

Installations for dust-free coke extraction from coke ovens (hereinafter referred to as the installation) are known and used in both domestic and foreign practice.

In particular, a plant is known that includes a door-removing machine with a dust-extraction hood, a collector for removing dust and gas products, installed on supports along the front of the coke oven battery parallel to the movement of the door-removing machine.

Analogue: A.s. No. 947173, class C10B 33/04.

The disadvantage of this invention is that the umbrella installed on the door-removing machine does not have devices for creating a uniform distribution of the unloaded coke from the coke oven into the coke wagon in order to prevent the accumulation of unloaded coke beyond the dimensions of the wagon body.

Known patent No. 2177976, class C10B 33/00.

A device for reducing harmful emissions during coke discharge from coke ovens.

This device does not have a device for uniform distribution of the unloaded coke into the coke car.

The essence of this proposal is that the hood is equipped with two distribution devices for uniform distribution of coke output, located in the hood offset in its extreme parts, in the axis of the coke car tracks, each distribution device contains a shaft with a blade, installed vertically, with the possibility of reciprocating turns by 30°-70° using a crank mechanism drive, or the hood is equipped with one distribution device installed in the hood axis in a vertical plane relative to the coke oven, from which coke is unloaded into the coke car.

The application of the proposed invention in the coke industry will allow:

1. Ensuring uniform distribution of coke discharged from the coke oven into the coke wagon or coke quenching wagon.

2. Elimination of accumulations in the body of the wagon of coke unloaded from the coke oven, beyond their height dimensions.

3. Improving the safety efficiency of dust-free coke delivery from a coke oven battery.

Examples of devices are shown in the figures.

The installation includes: a door-removing machine 1, to which an umbrella 2 is attached, which is equipped with two distribution devices 3 for uniform distribution of coke delivery, located in the umbrella offset in its extreme parts, in the axis of the tracks of the coke car 15, the mechanism contains a shaft 8 with a blade 9, installed vertically to bearings 11, 12, secured in brackets 13, 14, which are secured to the umbrella 2, with the possibility of reciprocating turns by 30°-70° using a crank mechanism drive.

Operating principle of the device

Before coke is discharged according to the schedule from the coke oven of the coke battery, the door-removing machine 1 is installed on the specified coke oven, the coke door is removed, and at the same time the coke car 15 is installed under the hood 2 for loading coke. Before coke is discharged into the middle part of the hood 2, into the coke car 15, in the hood 2 the distribution devices 3 with a vertical shaft 8 with a blade 9 are switched on, performing reciprocating turns by 30°-70°, which makes it possible to evenly scatter the unloaded coke into the coke car 15, after unloading the coke the distribution device 3 is switched off.

Claims (1)

An hood for uniformly distributing the discharged coke into a coke car, which is part of a dust-free coke discharge unit from a coke oven, containing a door-removing machine to which the hood is attached, a coke car, characterized in that the hood is equipped with two distribution devices for uniformly distributing the coke discharge, located in the hood offset in its extreme parts, in the axis of the tracks of the coke car, each distribution device contains a shaft with a blade, installed vertically, with the possibility of reciprocating turns by 30°-70° using a crank mechanism drive, or the hood is equipped with one distribution device installed in the hood axis in a vertical plane relative to the coke oven, from which coke is discharged into the coke car.
