Definitions
- the invention relates to a strain-free stationary furnace door operation for a coke oven plant of the "heat recovery" type, through which a vertical opening of the coke oven chamber doors without use of a Koksofenbedienungsmaschine is possible, the deviations of the traction elements of the furnace door operation of the target assemblies, which are characterized by the
- the invention also relates to a method for the expansion-free, stationary furnace door operation of a coke oven plant of the type "" which results in expansions of the transfer devices and undesired tensile force reinforcements, which result from differences in the adhesion forces of the coke oven chamber during closure, by the use of expansion-poor transmission devices and tension elements.
- Heat recovery which uses rigid tension elements and strain-free transmission devices for the automatic opening and closing of coke oven chamber doors.
- yklisch wherein the coal is first loaded into the coke oven chamber for coking, the coal is coked to coke, and the finished coke is then expressed from the coke oven chamber.
- the coke oven chamber doors In order to be able to carry out this cyclical mode of production, the coke oven chamber doors must be opened and closed again after loading and after squeezing. Since this process is time-consuming and technically demanding due to the temperatures used during the coking, there are in the prior art a number of methods that perform the process of opening and closing coke oven chamber doors by machine.
- WO 01/18150 A2 describes a system of coke oven chambers, secondary heating chambers, cooling air ducts under the coke oven chambers, air supply ducts, control devices for the admission of air into the air supply ducts, exhaust gas collecting ducts, coal loading machines loaded from the ceiling of the coke oven compartments, expressing machines, which express from one side of the coke oven chambers, and fire trucks that receive the coke on the opposite side of the coke oven chambers, coke oven chamber doors, door opening and closing mechanisms, coal storage devices, a quench tower, and an exhaust gas collection channel to the boiler devices.
- This teaching discloses an opening and closing mechanism for coke oven doors, which opens the doors vertically by pulling force with a hydraulic drive device, wherein the pulling force is transmitted with ropes, which is converted via pulleys in a horizontal tensile force, so that the pulling device horizontally and against the rope can transport a counterweight.
- DE 144947 C describes a device for raising and lowering coke oven chamber doors, in particular of coke ovens by means of a force associated with a rod, a frame or an equivalent type device force cylinder and guided over rollers, acting on the furnace doors traction means, wherein the in the front direction of the ovens movable rod or the like is provided with a plurality of traction means, so that several furnace doors can be lifted simultaneously as needed.
- This device also has the disadvantage that the automated operation of a whole Koksofenbank with the individual coke oven chambers is not possible because an actuator for a single power transmission mechanism is not present, and that the transmission of the tensile force is carried out with a simple rope.
- DE 98545 C describes a device for opening and closing coke oven chamber doors with which the coke oven chamber doors can be raised and lowered mechanically and from a common point arranged in a coke oven bank or coke oven battery above the coke oven chamber a wind in the front direction arranged wind, the traction means can be connected on the one hand to a fixed power source, on the other hand to one of the coke oven chamber doors, for the purpose of each of the adjacent doors from one point to be able to pull up.
- the invention does not allow automatic control of a single Koksofensch, but only a driving the individual Koksofenschen by hand. The automated operation of a whole coke oven bank with the individual coke oven chambers is thus not possible.
- Another problem is that a power transmission system is used that does not meet the mechanical requirements of a modern coke oven door opening mechanism.

- the mechanism does not allow centimeter-accurate operation of the movement mechanism, since the chains or ropes used are stretchable, and are stretched during operation by the high tensile forces. Also, the gripper cam used is exposed to the gripper carriage high tensile forces.
- the coke oven doors also stick together during the coking process through the coking products deposited in the doors, so that a high tensile force must be used for opening, which differs depending on the degree of adhesion.
- the ropes used must be dimensioned accordingly strong, which brings correspondingly high investment and operating costs.
- the towing vehicle should be designed so that it can be dispensed with risk of breakage gripper cam.
- the invention solves this problem by a device which Koksofenschen, which close the coke oven chambers frontally, with a tension element which is equipped with a break and stretch-proof tow hook, opens or closes vertically, wherein a train carriage, which horizontally on a guide device runs along the coke oven chamber front, is connected by a transmission device which is fixedly connected to the train carriage via a link mechanism with the tension member on request, and the train carriage is connected to the transfer device via pulleys fixed to the coke oven chamber doors, and the tension member as well as the transmission device is rigid and expansion-free, so that the coke oven chamber open vertically at a horizontal movement of the tension element at the request of the connection mechanism or close.

This is measurable above all on the overstroke device of the hydraulic cylinder on the tension element, which is set by way of example to an overstroke of at most 150 mm. This overstroke compensates for both the different door lift and the chain extension.
- the drive unit can run temporarily or permanently, depending on the duration of the coking process and the number of coke oven chambers to be operated. If this runs temporarily, it can be requested or started, for example, by a radio transmission mechanism. This can also run permanently and be engaged for the displacement process.
