Abstract

1. Door for a coke oven with horizontal chambers, having an integral or multiple-part protecting shield combined with the body of the door, extending into the oven chamber, which also serves as a heat shield, above which the oven filling is maintained at a given spacing from the body of the door, whereby the body of the door, during the coking process, is pressed against the door frame of the oven with a bolting device, characterised in that at least one further integral or multiple-part shield is positioned between the protective shield and the body of the door.

(54) DOOR OF THE HORIZONTAL COKE OVEN CAMERA

(57) The invention relates to the equipment of coke ovens. The purpose of the invention is to improve the reliability and tightness of the door by maintaining the stability of the shape of the protective screen under operating conditions. This goal is achieved by supplying the door of the horizontal chamber of a coke oven with a sealing unit and a venting channel with a protective screen made of two or more thin-walled parts placed at a distance connected by the principle of mirror symmetry using interchangeable spacers. channel. The door also contains movable seals. 4 hp f-ly, 12 ill.

The invention relates to coke oven equipment, in particular, to a door of a horizontal coke oven chamber ,.

The purpose of the invention is to increase the reliability and tightness of the door by maintaining the stability of the shape of the protective screen under operating conditions,

Figure 1 shows the door installed in the opening of the horizontal chamber of a coke oven, horizontal section; in fig. 2 - the proposed door, a partial vertical section; in fig. 3 - various types of protective screen, cross section; in fig. 4 - door, vertical section; on league. 5 - the same, with a large distance between the parts of the protective screen; on league. 6 - the door

with a protective screen, each part of which is made of a composite, vertical section; on league. 7 - a door with a protective screen, between which parts sealing gaskets are placed, a horizontal section; in fig. 8 - protective shield with sealing gaskets in the raised and lowered positions in the furnace chamber, partial section; on league. 9 - connection of parts of the protective screen with a gasket placed between them; in fig. 10 is a section A-A in FIG. 9; in fig. 11 - door body with locking device, side view; in fig. 12 - door during operation.

The door of the horizontal chamber of a coke oven contains a housing 1 made of a hollow profile, equipped with an extension

by means of 2 closing, sealing unit 3, made in the form of a plate, attached to frame 4 through sealing gasket 5 by means of spring screws 6, evenly spaced around the circumference of frame 4. Sealing unit 3 is made in the form of a hollow insulated mass profile 7 and is provided with a coating 8, cHa6, with steel angles 9 distributed in height, which are connected with additional steel angles 11 with screws 10, which are fixed, for example, by means of hooks 12, a protective screen 13 made of Vuh arranged spaced thin-walled portions 14 and 15 connected according to the principle of mirror symmetry by means of removable rock By arranging 16 placed at uniformly spaced adjustment parts, and the bolts 17 passed through the spacer 16. Between the part 15 of the shield

13 and the withdrawal unit 3 formed an exhaust duct 18, and between parts 14 and 15, an additional exhaust vent channel 19, open along their lateral sides, was formed. Parts

14 and 15 of the protective screen 13 are made of figured profiles, the possible embodiments of which are shown in FIG. Parts 14 and 15 can be made composite with the help of hinges 20, which is represented in Fig. 6. At least laterally between Parts 14 and 15 can be mounted on the side

 at least one sealing gasket 21, provided with an inclined slot 22, through which the bolt 17 is passed. The sealing gaskets 21 should fit as closely as possible to the part 15 in order to prevent gas from entering the exhaust duct 18 and thereby relieve the seal assembly 3 and the gasket 5, The sealing gasket 21 communicates with the wall 23 of the furnace chamber by means of a rod 24.

The sealing gasket 21 is preferably made S-shaped. At the same time inside it is adjacent to the outer part 15, and outside the part 14 and the sealing gasket 21 there remains a vertical gap 25 for the passage of gas. The corners 1I are directly attached to the cover 8. The body 1 is hollow and has a longitudinal 26th transverse 27 beam. The longitudinal beam 26 is open at the upper and lower ends. In addition, the longitudinal beams 26 at the points of connection with the transverse beams 27 are made with openings so that air flows unhindered from the transverse beams 27 into the longitudinal beams 26 and from there upwards where it can go. The door is equipped with two closing devices 2 which move together with the help of a rod 28. The closing devices 2 are controlled by a lever mechanism (not shown). For power closing with case 1, the closing devices 2 are screwed 29 to the plates 30 welded at the top and bottom with transverse bars 27. Between the plates 29 and 30, compensation plates 31 are provided, which are auxiliary means for adjusting the fixture 2 to the fixed hooks (not shown) on the furnace. In order to cooperate with the device for mounting the door with the bolts 32 of the closing device 2, under the bolt 32, the crossbar 27 is provided with a recess 33. In addition, between the closing devices 2 and the transverse beams located under them. 27, stiffening ribs 34 are provided. A fork 35 is welded on each top crossbar welded to the plate 29, which covers the hole 36 located on the sealing unit 3, and the hole 36 and the fork 35 form together with the bolt 37 the hinge mounting of the sealing unit 3 on the body 1.

The device works as follows.

The sealing of the device is achieved by using a protective screen 13, made of two mirrored parts 14 and 15 and serving simultaneously as a heat insulator. The profiles of portions 14 and 15 are interconnected with a gap sufficient for thermal expansion. Sealing gaskets 21 should be tightly attached to the outer profile to prevent gas from entering the outer channel between the above profile and the door body, it is installed with the possibility of movement, and when the protective screen is lowered, the seal should rest on the chamber walls.
