Description

The invention relates to the equipment of coke shops, namely mechanical devices for cleaning frames and armor of coke ovens from soot.

During the coking of the coal charge in the coke ovens, the resin is condensed on their fittings (frames and armor x) and deposited in the form of solid carbon. After each delivery of coke from furnaces, carbon with frames and armor must be removed in order to maintain a constant size and create conditions for the tightness of coke ovens with the exception of atmospheric pollution at coke-chemical plants.

To remove the specified carbon deposits, coke oven frame and armor cleaning devices are installed, which

on machines for unloading coke ovens (coke pusher and door-lifting machine)

Devices are known in which the cleaning workers move along a closed path around the surfaces of the coke oven to be cleaned.

Devices are known whose working bodies for cleaning which move reciprocally relative to the surfaces of the coke oven to be cleaned.

Known devices, the working bodies of which make a combined movement, such as rotational and simultaneously reciprocating along the cleaned surfaces of the coke oven frame.

Devices for cleaning frames and armor of coke ovens are also known, whose working bodies oscillate along the cleaned surfaces of the frames and armor.

Closest to the present invention is a device for cleaning frames and armor of coke ovens, which comprises a vertical frame and a carriage mounted movably on it with a reciprocating drive. On the carriage, by means of a spring suspension and support rollers, an additional carriage with a cross bar is installed, carrying on itself the side and end cleaning elements, made on smde scrapers. The side cleaning elements are interconnected with a hinged lever system, one of the levers of which is hingedly mounted on the traverse, and the other two-link lever is hingedly interconnected with a movable spring-loaded rod, which is interconnected with an additional carriage. End clearing alements are installed on a spring-loaded traverse by means of guides installed on its two sides.

When the guide moves, due to the interaction of the abutment with the surface of the furnace, spring suspension with rollers and hinges, the scraper self-aligns in the horizontal plane relative to the surface to be cleaned, and due to the hinged installation, the cutters of the side scrapers self-align in the vertical plane.

A disadvantage of the known device for cleaning frames and armor of coke ovens is the presence of an additional carriage carrying side scrapers equipped with a hinge system, one arm of which is pivotally mounted on the crosshead of the carriage by means of a lever, the other by means of a hinged two-link lever interconnected by a spring-loaded movable spindle in the cross bar. All this complicates the design of the device, and the presence of a large number of hinged connections in the lever system of side scrapers reduces the operational reliability of the device.

The aim of the invention is to simplify the design of the device and increase its operational reliability.

In the known device for cleaning frames and armor of coke ovens, including a guide frame, a movable carriage mounted on it, a carriage reciprocating drive, side cleaning bodies movably mounted on the carriage, and transverse

end cleansing bodies, the carriage is provided with additional end cleansing bodies, which are fixed in pairs on spring-loaded cross-arms, evenly

installed along the height of the carriage, oppositely located lateral cleaning organs are provided with a common elastic element movably mounted between them, and the transverse end cleaning organs are mounted on the carriage movably in mutually perpendicular planes and provided with elastic elements.

A comparative analysis with a known device suggests that

5, the proposed device for cleaning frames and armor of coke ovens is characterized by the presence of additional end cleaning organs, a new connection of side cleaning organs with elastic elements, and transverse end cleaning bodies with a carriage.

FIG. 1 shows a device for cleaning frames and armor of coke ovens, a general view. two projections; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; on

5 figure 4 - node I in figure 1.

The device for cleaning frames and armor of coke ovens contains a guide frame 1, a carriage 2 movably mounted in frame 1, and an actuator for reciprocating movement of carriage 2 including gear 3, chain transmission 4, sprockets 5 mounted on frame 1, and traction chains b mounted on sprockets 5 and connected to the carriage 2.

5 The guide frame 1, by means of the articulated support 7 and the locking elements 8, is mounted on the supporting metalwork 9 of a machine for servicing coke ovens.

0 On the carriage 2, the extreme top 10 and bottom 11 face cleaning organs are mounted, which are transversely mounted and movably fixed in a vertical plane by means of a finger 12 and an elastic

5 of the element 13, and in the horizontal plane by means of a finger 14 in the guide groove 15 and the elastic element 16; side cleaning bodies 17, each pair of which is installed symmetrically and movably in a horizontal plane by means of grooves 18 in brackets 19 and hinges 20 and provided with a common elastic element 21, which is installed between guide pins 22 that evenly act on the housings 23 symmetrically located lateral cleansing organs; additional end cleaning bodies 24, which are fixed in pairs on the cross-arms 25, the latter are uniformly mounted along the height of the carriage 2, are movably connected to

it in the horizontal plane by means of the slots 26 in the brackets 27 and the hinges 28 and are provided with elastic elements 29 for uniform pressing of the cleaning organs 24 to the surfaces of the frame 30 to be cleaned.

The extreme upper 10 and lower 11 end organs of cleaning are made in the form of scrapers, the cutting edges of which are bent from three sides at an acute angle to the surface of the frame 30 to be cleaned.

The lateral 17 and additional 24 end cleansing bodies are made in the form of scrapers having two cutting edges, which are installed symmetrically with respect to their longitudinal axis at an acute angle to the surfaces of the frame 30 and broni31 to be cleaned31.

The operation of the device is controlled by the commander and the limit switch (not shown), which control the set end positions of the carriage 2.

The device for cleaning frames and armor works as follows.

By means of the supporting metalwork 9 of a coke oven servicing machine (not shown), the device is installed along the axis of the coke oven frame 30 and guided to it. At the same time, the side cleaning bodies 17 come into contact with the side surfaces of the frame 30 and the armor 31 and pre-center the device by moving the hinge support 7 and the locking elements 8. The final centering of the device relative to the frame 30 is performed by the rollers 32, which are included in contact with hooks (not shown) of the frame 30. Then the device, overcoming the resistance of the springs 29 of the cross-arms 25 and the springs 16 mounted on the fingers 14, continues its movement towards the furnace and is set to a position in which the upper 10 and lower 11, the end cleaning bodies and the additional end cleaning bodies 24 occupy an operating position for cleaning the mirror frame 30, while the side cleaning bodies 17 also, having overcome the resistance of the springs 21, occupy an operating position. The pressing force of the cleaning bodies 10, 11, 17 and 24 is provided by the respective springs.

Then the drive is turned on, the gearbox 3 of which returns the sprockets 5 through the chain transmission 4, moving the drag chains b and giving the carriage 2 a reciprocating motion. The latter, from the initial position (Fig. 1), first moves upwards, then the commander (not shown) switches the drive to the full stroke of the carriage 2 down and to a short stroke from the bottom

up to the starting position. In the process of moving the carriage 2, the upper 10 and lower 11 and additional 24 end cleansing bodies clean the mirror of the frame 30 along its entire height, as well as in the upper and lower parts, and the side cleaning bodies 17 clean the side surfaces of the frame 30 and armor 31.

During the operation of the coke oven, their other frames and armors receive deviations from the design position in the vertical-transverse and vertical-longitudinal planes, as well as the height displacement of the frames. Compensation of these deviations in the process

5, the device is operated by moving the cleaning bodies 10, 11, 17 and 24 on the carriage 2. Thus, the vertical-lateral deviations of the frame 30 are compensated by the mobile installation of

0 cleaning bodies 10, 11 and 24 in the horizontal plane, vertical-longitudinal deviations of the frame 30 and armor 31 are compensated by moving the side cleaning bodies 17 in a horizontal plane, and 5 hundredth displacements of the frames 30 on the coke battery are compensated by moving the cleaning bodies 10 and 11 in the vertical plane.

After cleaning the frame 30 and the armor 31, the device is removed from the working position to the initial position and, by moving the machine for servicing the coke ovens, is installed to clean the next frame and the armor of the coke oven.

5 The proposed device for cleaning frames and armor of coke ovens, in comparison with the known, has a simple and more reliable to operate design, which provides an effective and

0 high-quality cleaning of frames and armor. This is achieved by self-aligning the organs of cleaning with respect to the surfaces being cleaned and their uniform clamping to these surfaces at possible, within 5 given limits of the design deviations of the position of the frames and armor on the coke oven batteries.

Increasing the operational reliability of the device increases its life

0 service is about 1.3-1.5 times and reduces by about 40% the cost of its repair and maintenance.
