Abstract

The invention relates to the coke industry, namely to devices for cleaning coke oven doors from tar and graphite deposits. The invention makes it possible to improve the quality of cleaning and the reliability of operation of the device for cleaning doors of coke ovens. The device comprises a guide frame on which the side and end carriages with working bodies made in the form of drums are fastened. Each drum consists of a cylindrical body, to the shell of which a flange and bushings are welded. The reels rotate on an axis supported by a spherical bearing. The lower part of the axis is made conical and interacts with the inner conical surface of the support flange. The drum bushings interact with the teeth mounted on the guide frame in increments equal to the pitch of the sleeves on the drum. The device provides self-installation mechanism, ensures a tight fit of the brushes to the surface being cleaned and contributes to its high-quality cleaning. 3 hp f-ly, 10 ill.

Description

The invention relates to the coke industry, namely to devices for cleaning coke oven doors from tar and graphite deposits.

The purpose of the invention is to increase the reliability of the mechanism and the quality of cleaning of coke oven doors.

FIG. 1 shows a device for cleaning coke oven doors, a general view; in fig. 2 - the same, side view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. 2; in fig. 6 - section G-Y in FIG. five; in fig. 7 — node I in FIG. 3; in fig. 8 — node II in FIG. four;

in fig. 9 is a view of D in FIG. one; in fig. 10 is a section through L-H in FIG. 3

The device for cleaning the doors of a coconut oven contains a guide frame 1, on which drive 2 is fixed, upper sprockets 3 and lower sprockets 4. Thrust chains 5 and 6 are thrown through sprockets 3 and 4. The latter have racks 7 and 8 on which crepe vehicle side carriages 9 and 10 and end carriages 11. On carriages there are fixed side 12 and end 13 working bodies, made in the form of drums. Each drum consists of a cylindrical body 14, to the shell of which a flange 15 is welded. And sleeves 16. From the top, the drum is closed with a lid 17. The drums fit with VI

Spread on an axis 18 supported by a spherical bearing 19, which is secured by a nut 20 and a cotter pin 21.

The lower part 22 of the axis 18 is tapered and interacts with the inner conical surface of the support flange 23. The position of the latter and the spherical bearing 19 is adjusted by washers 24. The axis 18 is welded to the bracket 25 fixed by means of the axes 26 on the levers 27 and 28 mounted on carriages 9 eleven.

The drum bushings 16 cooperate with the teeth 29 mounted on the guide frame 1 in increments equal to the pitch of the sleeves 16 on the drum.

In order to orient the drum to a position that prevents breakage or deformation of the cleaning elements of the working bodies when the door is fed for cleaning, brackets 30 are installed on the bracket 25, in the slots of which axles 31 rollers 32 are installed. Springs 33 are mounted on opposite ends of the fork in glasses. The latter are welded to the bracket 25. The force of pressing the rollers to the drum is adjusted by screws 35 and fixed by nuts 36.

To clean the side surfaces of the door on the cylindrical surfaces of the drums mounted on the side carriages 9 and 10, side brushes 37 are fixed, made in the form of pieces of cables. The brushes 37 are fastened with clamping strips 38, bolts 39 and nuts 40. Grooves 41 are made on the flanges of the drums of the side carriages 9 and 10 for laying the cables.

On the drums mounted on the end carriages 11, end brushes 42 are mounted, which are fixed by a welded faceplate 43, bolts 44 and nuts 45. End brushes 42 can be made, for example, of steel cable strands 46, pre-bent and spring-loaded. The straps are connected to springs 47 (for example, plate-like helical) with the help of brackets 48, gaskets 49. bolts 50 and nuts 51.

The drums mounted on the side carriages 10 are additionally provided with scrapers 52, made, for example, in the form of earrings made of sheet steel, welded to the rings 53, which are fastened to the drums with bolts 54.

The device works as follows.

For cleaning, the door 55 is supplied to the area of operation of the door cleaning device. When the conical surface 22 of the axis 18 interacts with the conical surface 56 of the flange 23, the working members self-align with the door to be cleaned, which, when the door is further fed, prevents the cleaning elements of the working bodies from breaking. Drive 2 is turned on, and workers

the bodies of the side and end carriages move in the guide frame 1. The sleeves 16 of the drums 14, interacting with the teeth 29 of the guide frame, rotate the drums with cleaning elements that are brushes

37, scrapers 52 and face brushes 42 clean the coke oven door from graphite and resinous deposits. Through 1 - 2 carriage transitions around the perimeter of the door, the carriage moves in the opposite direction.

In comparison with the known, the proposed device improves the quality of cleaning the doors of coke ovens, since, by ensuring the self-installation of the mechanism, it guarantees

optimal adherence of brushes to the surface being cleaned, which contributes to its high-quality cleaning.

In addition, self-installation of the working body of the device for cleaning coke doors

stoves prevent it from inaccurate installation, which increases reliability.
