Description

The invention relates to the mechanisms and devices used in the coke chemical process.

for disintegration to the device;: for the operation of coal extraction in the coking chamber.

Known device

for leveling the charge in a coke oven. including a horizontal platform, racks mounted on it and a planned 10 bar with led :. its horizontal movement. On the bar, the i-shift is strengthened.

As a result of the reciprocating, 15 movements of the leveling rod, a considerable part of the coal charge (up to 2%) is removed from the coking chamber, which leads to additional costs for returning the coal charge to the chamber and 20 to the dusting of the atmosphere, and ultimately reduced performance of coking chambers.

The closest to the present invention is a device for leveling 25 NIN charge in a coke oven, including a horizontal platform, racks mounted on it and a leveling rod with a drive for its horizontal movement mounted on racks.

Nirna rod is made in the form of a screw

The drawbacks of the known construction are: the impossibility of completely eliminating the charge rake by the auger, since the charge may fall out through the gaps between the screw and the metal frame, and the reduction of these gaps leads to a rapid wear of the screw, an increase in the bending stresses in the leveling bar and, as a result, a shorter time service due to the presence of a screw auger, which leads to an increase in the weight of the leveling rod, the inexpediency of the use of universal joints and outboard bearings, since noy dust, they cha.sto exit down, which leads to dopolnitelnElm repair costs.

The purpose of the invention is to increase the productivity of the furnace by eliminating the charge of the charge during its planning.

This goal is achieved by the fact that the device for leveling the charge in a coke oven, including a horizontal platform, racks mounted on it and a horizontal rod with a drive for its horizontal movement, installed on drains, is equipped with a nozzle for supplying air, mounted on a horizontal platform and having a drive filing it in the oven.

FIG. 1 shows the device, a general view; FIG. 2 shows a nozzle for supplying air with a drive; FIG. 3 - the same, in the working position, in FIG. 4, the same, front view.

The device for leveling the charge includes a horizontal platform 1, racks 2 mounted on it, a leveling rod 3 with a drive 4 of its horizontal movement.

On a horizontal platform 1, a 5 lance was mounted for air supply, having a drive 6 for supplying it to the furnace. On a horizontal platform 1, posts 7 are mounted for fastening the pipe 8. A movable rod 9 is placed in the pipe 8, connected by means of a lever 10 and a holder 11 with a nozzle 5. The nozzle 5 is equipped with a hose 12 for supplying compressed air.

Before the next coal charge planning in the coke oven chamber, the nozzle 5 is fed to the lower part of the planned hatch 13 (Fig. 3). The feed nozzle 5 is as follows. When the actuator 6 is turned on, the movable rod 9, traversing 500 f / m along the pipe 8, rotates with the lever 10 by means of a spike 14 and a guide groove 15 by 90 and with further movement is fed into the neck of the hatch 13 to its lower part. After this, planning begins. Moreover, the planned rod 3 moves over the nozzle 5. With the return of the planned rod 3, air passes through the hose 12 to the nozzle 5. The device of the nozzle 5 allows to distribute the flow of compressed air in two directions. The horizontal jet is directed along the base of the planned hatch 13, loosening Em pushes the charge, pushes it into the coke oven chamber and raises it to the top of the design hatch. The second jet is directed upwards at an angle of 20-30- and creates a curtain in the P5LAYUYY so that the resulting vortices and a raised charge are not ejected from the planned hatch 13,

During the forward stroke of the leveling rod 3, compressed air is supplied through the nozzle. 5 is terminated.

The nozzle 5 consists of the upper plate 16, the bottom plate 17, the dissector 18, the liner 19 and the end plates 20.

 During the operation of the mechanism, the air enters through the openings 21 of the insert 19 into the cavity of the nozzle 5, where by means of the dissector 18 it is divided into two jets,

The use of the proposed plunger device leads to the complete elimination of the coal charge from the coke oven chamber during planning, which makes it possible to increase productivity, reduce the cost of maintaining the equipment of the coke shops by reducing the amount of equipment for these purposes (their production chain is excluded). workshops skip hoists mechanisms

5 collisions of the charge, bunkers for the collection of the subplanar charge). Reducing the amount of equipment also reduces depreciation.
