Definitions
- the invention relates to a coke oven door with a door body which closes an opening of a coke oven chamber.
- the coke oven door is especially designed for a heat recovery coke oven.
- a sealing arrangement is provided, which cooperates with an associated sealing surface and seals the gap between the door body and a boundary of the furnace chamber opening.
- the boundary can be formed by a chamber frame or individual elements.
- the sealing arrangement comprises at least one metal strip resting against the sealing surface with a narrow side and a plurality of actuating means acting on the other narrow side of the metal strip.
- a coke oven door with the features described above is known from DE 27 55 020 A1.
- the seal assembly of the known design has a metal strip which rests with a blade-like beveled narrow side to a sealing surface of the chamber frame.
- adjusting means On the other narrow side of the metal strip act adjusting means which are arranged circumferentially and spaced apart on the circumference of the door body.
- a membrane or a flexible sealing plate is arranged, which encompasses the entire area surrounded by the metal strip area
- this additional sealing element which must be designed to be flexible, is likewise subject to strong stresses due to temperature and deformations. An exchange of the membrane is expensive.
- the basic structure of the coke oven door includes a door body which closes an opening of a coke oven chamber, and provided on the door body seal assembly which cooperates with an associated sealing surface and seals the gap between the door body and a boundary of the open-chamber opening.
- the sealing arrangement comprises at least one with a narrow side on the sealing surface fitting metal strip and a plurality, preferably in the corner regions of the door body to the other
- the metal strip is displaceably arranged in a guide slot and can be fixed by retaining means in the corner regions of the door body in the guide slot against falling out.
- the guide slot and recesses for the actuating means are integrated in the door body.
- the metal strip can be guided on both sides and so tight in the guide slot that a gas passage between the door body and metal strip is almost impossible.
- the acting as a seal, arranged in the guide slot of the door body metal strip is suitably fixed in the corner regions of the door body by the adjusting means in the guide slot, while the metal strip is held in intervening central areas of the door body, so to speak "floating" in the guide slot.
- no adjusting means are provided or the adjusting means are formed in this area as resilient elements.
- the door body is heated to its furnace chamber side facing stronger than at its other, outer side, which is why the door body can bend strongly due to the thermal changes in length.
- the door body will bend outwardly away from the warm side in the manner of a bi-metal effect at its edges, so that it is curved in particular in the direction of the furnace chamber along the height of the door body.
- the adjusting means for the metal band provided as a seal are arranged exclusively in the corner regions of the door body, the metal strip can deflect in the guide slot and thus compensate for the curvature of the door body.
- the metal strip is movably guided over at least 80% of the width of the door body and at least 80% of the height of the door body in the guide slot.
- a spring or the like can be arranged in this area, but this only exerts a comparatively small force on the metal strip and is not provided with adjusting means. In many applications, however, such a spring or other elastic deposit of the metal strip due to the clamping on the corner regions of the door body is not necessary.
- the metal strip in the guide slot must be sufficiently movable.
- An adjustment path of at least 10 mm, particularly preferably at least 20 mm, is preferably provided in an area which is medium in relation to the height.
- the use of separate positioning and holding means allows both a fast and precise adjustment of the contact pressure of the metal strip as well as a quick and precise adjustment of the metal strip on the actual existing geometric conditions of the chamber frame or the boundary of the opening of the furnace chamber.
- the metal strip is preferably made of a steel sheet.
- the metal strip is arranged in an edge region of the door body.
- the associated sealing surface is formed by a surface of the chamber frame or by surface elements of a boundary of the furnace chamber opening formed from a plurality of individual elements.
- the arrangement of the retaining means in the corner regions of the door body leads to a decoupling of the thermal bending of the metal strip from that of the door body.
- the distance between the door body and the sealing surface of the chamber boundary in the corner region of the coke oven doors can be set precisely by advancing or returning the metal strip via the adjusting means arranged in the door body.
- the distance set in the corners of the coke oven door remains constant throughout the coking process.
- the door body due to the decoupling of the bending of the metal strip can move freely back and forth without the metal strip thereby losing contact with the sealing surface of the boundary of the opening of the furnace chamber, and thus its sealing effect. This realizes a reliable sealing of the oven chamber over the coking time.
- the adjusting means are designed as adjusting screws, which are screwed into threaded bores and accessible on the outside of the door body. Adjusting screws are a particularly precise and easy-to-use adjusting means. With them, the position of the metal strip within the door body and thus the distance between the door body and sealing surface of the chamber-side boundary can be set with great accuracy. The accessibility of the actuating means from the outside, the metal strip can be readjusted if necessary, during the coking process.
- the power transmission between the screws and the metal strip is carried out either directly or indirectly via a cylindrical pin which is arranged between the adjusting screw and the metal strip and slidably guided in a cylinder bore.
- screw or plate springs can be arranged between adjusting screws and metal strip.
- the retaining means consist of stud bolts, which are screwed into threaded holes and accessible on the narrow side of the door body.
- the stud bolts engage in holes in the metal band and lock it securely against falling out.
- the holes in the metal strip allow the metal strip to be pushed back and forth in the corner regions of the door in a defined area.
- FIG. 1 is a sectional view of a coke oven door with a seal assembly according to the invention
- FIG. 2 shows a detail view of the sealing arrangement from FIG. 1 in the region of the lower edge of the coke oven door
- FIG. 3 shows a front view of the coke oven door from FIG. 1.
- a coke oven door To the basic structure of a coke oven door according to the invention include a door body 2, which closes an opening of a coke oven chamber 3, and provided on the door body 2 seal assembly 4, which cooperates with an associated sealing surface 13 and the gap 5 between the door body 2 and the sealing surface 13 at a Boundary 1 of the furnace opening seals.
- the seal assembly 4 comprises at least one voltage applied to a narrow side of the sealing surface 13 metal strip 6 and a plurality on the other narrow side of the metal band 6 acting adjusting means 7.
- the metal strip 6 a steel strip is preferably used.
- the metal strip 6 is arranged displaceably in a guide slot 8 and can be fixed by holding means 9 in the guide slot against falling out.
- the holding means 9 are arranged in corner regions of the door body 2.
- the guide slot 8 and recesses for the adjusting means 7 are integrated in the door body 2.
- the metal strip 6 is disposed in an edge region of the door body 2 and the associated sealing surface 13 is formed by a surface of the boundary 1 of the furnace opening.
- the seal assembly 4 is shown in an edge region. It is understood that in several edge regions of the door body such sealing arrangements can be provided individually, continuously and / or circumferentially.
- the adjusting means 7 are designed as set screws, which are screwed into threaded holes and accessible on the outside 10 of the door body 2. As a result, the metal band 6 can be readjusted even when the door is closed.
- the power transmission between the screws 7 and the metal strip 6 is carried out either directly or indirectly via a cylindrical pin 1 1, which is arranged between the adjusting screw 7 and the metal strip 6 and slidably guided in a cylinder bore.
- screw or plate springs 14 may be arranged between the adjusting screws 7 and the metal strip 6.
- the cylinder bore has a diameter which is greater than the width of the guide slot 8, but smaller than the diameter of the threaded holes for the screws 7.
- the holding means 9 consist of studs screwed into threaded holes in the door body 2 and on the narrow side 12 of the door body 2 are accessible. The holding means 9 are used to secure the metal strip 6 with the coke oven door open against falling out.
- the threaded pin 9 engages in a bore 6a of the metal strip 6.
- the bore 6a has a diameter which is greater than the outer diameter of the threaded pin 9 in order to allow a free displaceability of the metal strip 6 in the guide slot 8 when the coke oven door is closed.
- the adjusting means 7 are arranged close to the edge of the door body 2 for adaptation of the seal assembly.
- the door body 2 is supported at its lower end with rollers on a bracket.
- the support surface of the console is designed obliquely, so that the door body can not roll away from the oven chamber. At its upper end
- the metal strip can be driven out of the door body.
- the protrusion of the metal strip 6 defines the desired distance of the door body to the furnace front.
- the inventive arrangement, the metal strip 6 and thus the distance between the door body and the furnace front can be placed in a control range of, for example, ⁇ 10 mm. It can be achieved by the measures according to the invention that the distance between the door body and the furnace front is constant for each time of the coking process. A locking of the coke oven door, for example by a bolt lock is not absolutely necessary.
- the adjusting means 7 are arranged exclusively in the corner regions of the door body 2. Between the adjusting means 7, the metal strip 6 is movably guided in the associated guide slot 8, optionally optionally a slight elastic support is provided. Since the metal strip 6 can deflect into the guide slot 8, bends of the door body 2 can be compensated. Due to the thermal expansion, the door body 2 normally bends in such a way that a region of the coke oven chamber 3 which is medium in relation to the height is approximated. A reliable seal can already be achieved in that the metal strip 6 is resilient in the central region by the adjusting means 7 in the central region due to its bias in the corner regions. At most, a slight resilient support of the metal strip 6 is provided to push this in the direction of the boundary 1 of the furnace opening. Adjusting means 7 are not provided outside the corner areas.
