Definitions
- the invention relates to a device for lifting furnace doors of a coking furnace
- a door lifting head which can be coupled to vertically extending furnace doors of a horizontal chamber furnace
- a suction hood that can be moved along the horizontal chamber furnace above the furnace doors.
- the invention has for its object to improve the extraction of the emissions occurring when opening the furnace door.
- sealing elements are connected to the door lifting head which can be moved on both sides of an oven door to be opened against front-side contact surfaces of the horizontal chamber oven, essentially over the entire height of the oven door extend into the extraction area of the extraction hood and form a suction chamber for door emissions when the furnace door is opened.
- the sealing elements in contact with the front of the horizontal chamber furnace when the furnace door is opened limit a suction space that is open at the top and that opens into the suction area of the suction hood.
- the emissions that occur when the furnace door is opened are channeled and can be supplied to the exhaust hood with relatively small amounts of air.
- the arrangement according to the invention enables an almost complete recording of all emissions that occur when the furnace door is opened, in particular also from the lower door areas.
- the door lifting head expediently has mechanical, electromechanical, pneumatic or hydraulic actuating devices which control the actuating movements of the sealing elements.
- Control elements in such a way that the sealing elements lie against the front-side contact surfaces of the horizontal chamber furnace during a lifting movement of the furnace door coupled to the door lifting head from the door opening.
- the sealing elements are preferably designed as pivotably mounted wings. They can also be designed as sliding walls, which can be moved from a previous rest position in a rectilinear actuating movement against the front contact surfaces of the horizontal chamber furnace. There is also the possibility of forming the sealing elements in one or more parts.
- the coupling process of the door lifting device to an oven door to be opened is not impaired by the sealing elements provided according to the invention.
- the sealing elements are expediently movable between a rest position and a working position, wherein they are pushed back or pivoted back so far in the Ruhr position that the coupling process between the door lifting head and the closed furnace door can be observed.
- the arrangement according to the invention enables the use of compact and small suction hoods.
- the suction hood which can be moved along the horizontal chamber furnace preferably has a length which does not substantially exceed the chamber width of a furnace chamber of the horizontal chamber furnace.
- Suction lines connected to the suction hood, the suction fan and a subsequent filter system can be designed for relatively small flow rates.
- 1 is a horizontal section through a closed oven door of a coking oven and in plan view a device positioned in front of the oven door for lifting the oven door,
- FIG. 5 shows a further embodiment of the device according to the invention.
- a door lifting device on a coke pushing or coke transfer machine has a door lifting head 1, which can be coupled to vertically extending furnace doors 2 of a horizontal chamber furnace, and comprises a drive device 3, indicated only schematically, for actuating movements of the door lifting head 1. Furthermore, a suction hood is provided which can be moved along the horizontal chamber furnace above the furnace doors and the like Suction area 4 is shown in dashed lines in the figures. It is positioned above the door lifting device in front of the furnace chamber of the horizontal chamber furnace to be opened and, in the exemplary embodiment and in accordance with the preferred embodiment of the invention, has a length which does not substantially exceed the chamber width of the furnace chamber.
- Sealing elements 5 are connected to the door lifting head 1 and can be moved from a basic position I shown in dashed lines in FIG. 1 to a position II shown in solid lines in FIG. 1.
- Mechanical, electromechanical or hydraulic actuating devices are provided to control the actuating movements. Actuators with one or more hydraulic cylinders are preferably used.
- the door lifting head 1 is advanced from the position shown in FIG. 1 to the position shown in FIG. 2 and coupled to the oven door 2 to be opened.
- the sealing elements designed as pivotably mounted wings are spread out and assume the position II shown in FIG. 1.
- the coupling of the door lifting head 1 to the oven door 2 takes place in a manner known per se by hooking the lifting bar of the lifting head 1 into claws of the oven door 2.
- the sealing elements are pivoted back so far that the coupling process between the door lifting head 1 and the closed furnace door 2 can be observed.
- the wing-like sealing elements 5 are moved against front-side contact surfaces 6 of the horizontal chamber furnace and assume a working position III.
- the contact surfaces 6 are formed on anchor stands 7.
- the sealing elements 5 extend essentially over the entire height of the furnace door 2 into the suction area 4 of the suction hood and form a channel-shaped suction chamber 8 for door emissions when the furnace door 2 is opened.
- the lifting of the furnace door out of the door opening is shown in Fig. 3.
- the actuating movements of the sealing elements 5 are controlled by the associated actuating devices so that the sealing elements 5 bear against the front-side contact surfaces 6 of the horizontal chamber furnace during the lifting movement of the oven door 2 coupled to the door lifting head 1 from the door opening.
- the illustration shows that the wing-like sealing elements 5 move on the flanges of the anchor stands 7 in the direction of the furnace door 2.
- FIG. 4 shows the door lifting head 1 with the oven door 2 coupled in the pivoted position in front of an oven door cleaning device (not shown).
- the wing-like sealing elements 5 are in the basic position I.
- the sealing elements 5 are designed as multi-part sliding walls, which can be moved from a previous basic position in a rectilinear actuating movement against the front contact surfaces 6 of the horizontal chamber furnace.
