Description

The invention relates to the equipment of coke shops, in particular to doors of coke ovens with horizontal coking chambers

Coke oven doors are known from patent and scientific and technical information, the design of which provides a reduction in the deformation of the door body. A typical representative of such a door structure is a door including a housing carrying a spring bolt-type closures, a lining with a supporting frame fixed to the housing at a distance from it, and a sealing frame with a knife element secured around the perimeter of the lining supporting frame. The supporting frame with the sealing frame and the lining are rigidly connected to the casing in its middle part, and the fastening along the edges is made sliding. Such a connection of the supporting frame with the door housing allows them to independently extend from exposure to high temperatures (see the description of the invention for

USSR patent Mg 1072813 M. cl. C 10 B 25/06 of 12/14/77).

A drawback of such a door design is that the sliding joints during operation, which are exposed to heat and sticking with coal dust, are jammed and, at the same time, they are prevented from the independent thermal expansion of the door body and the supporting frame with a sealing frame and lining. As a result of this, the door is deformed and, as a result, the tightness of the coking chamber is broken.

The aim of the invention is to increase the tightness of the coke oven chamber.

In FIG. 1 shows a coke oven door, a longitudinal section; in FIG. 2 is a cross-sectional view of the door along AA in FIG. T; in FIG. 3-node G. on fig. 1, a longitudinal section through a hinge element: in FIG. 4 is a section BB in FIG. 3

The door of the coke oven (see. Fig. 1 and 2) includes a molded case 1, carrying the crossbar

ABOUT

shutters 2 and 3 interacting with hooks 4 of the frame 5 of the coke oven 6, a plate 7, a bearing sealing frame 8 and a lining 9. The housing 1 and the plate 7 are interconnected by means of the upper 10 and lower 11 hinge elements. The latter contain (see Figs. 3 and 4) brackets 12 mounted on the plate 7, brackets 13 mounted on the housing 1 in its openings 14 and installed between the brackets 12, and pins 15 vertically mounted in the holes of the brackets 12 and 13. moreover, the latter in the lower hinge element 11 are installed with a gap between each other.

On the housing 1 (see, Figs. 1 and 3), adjustable clamps are installed uniformly in height and symmetrical to the vertical axis of the door, made in the form of bolts 16, the end parts of which have spherical heads that interact with the edges of the plate 7, around the perimeter of the housing 1 evenly means 17 are fixed for pressing the sealing frame 8 against the mirror 18. frame 5 of the coke oven 6.

The door of the coke oven operates as follows.

In the working position (Figs. 1 and 2), the lining 9 of the door is installed in the opening of the chamber of the coke oven b, the knife of the sealing frame 8 is pressed against the mirror 19 of the frame 5 by means of 17, which are subjected to spacer forces. The latter are transmitted from the bolt bolts 2 and 3, which are meshed with the hooks 4 of the frame 5, through the housing 1.

To remove the door, a door-mounted device (not shown in the drawing) is brought in, the tear-off mechanism is put into engagement with the door grippers 19 and 20, and the mechanism is turned off. closing the bolts, acting on the bolt bolts 2 and 3, they are disengaged from the hooks 4 of the frame 5 and then the door is removed by the stall mechanism.

The installation of the door into the chamber of the furnace 6 is carried out in the reverse order.

If during operation of the coke oven b, there are cases of emissions of coke oven gas through the door seals due, for example, to the deflection of frame 5 in its middle

parts, then in this case, by the action of adjustable clamps 16 on the plate 7, it is bent in the middle part, giving the plate 7 an approximate shape of the bend of the frame 5. in order to avoid distortion of the shape of the sealing frame 8 in cross section when exposed to it by means 17. In other cases for example, during the initial installation of the door on the furnace, adjustable clamps 16 are unscrewed, if necessary, on one side of the door body 1, and on the opposite side they are screwed in and thus ensure uniform gaps between the walls of the chamber chi and lined doors on both sides of it.

The proposed door of the coke oven in comparison with the prototype provides a high degree of sealing of the chamber of the coke oven and virtually eliminates emissions

Claims (2)

1. The door of the coke oven, including the casing, bolt locks interacting with the hooks of the furnace frame, a plate fixed to the casing by hinge elements, bearing the sealing frame and lining, and means for pressing the sealing frame to the mirror of the furnace frame, releasing so that in order to increase the tightness of the coke oven chamber, the hinge elements are made with a vertical axis of rotation located along the axis of the door, and the body is equipped with adjustable clamps interacting with the edges of the plate. 2. The door according to claim 1, with the exception that the hinge elements are provided with brackets fixed to the body, and the plate is equipped with crotches, between which the hinge brackets are placed, and these brackets are installed in the lower part of the door with a gap between themselves.
