Device for operating the riser pipe cover arranged on the riser pipe of a coking furnace and the valve flap.

The invention relates to a device for actuating the riser pipe cover arranged on the riser pipe of a coking furnace and the valve flap.

When a coking furnace is detached from the template, the valve flap must first be opened in order to avoid the escape of raw gas be closed, which interrupts the connection between the coking furnace and template. Only then should the riser pipe cover opened, making the riser ear accessible for cleaning equipment. The reverse must be done when attaching of the coking furnace to the template, first close the riser pipe cover and only then open the valve flap.

These operations are usually carried out manually by the Operating personnel run on the furnace roof. It has also already been proposed to have an actuating device on the filling carriage to be provided in the filling position on the riser pipe cover assigned to the relevant coking furnace and the valve flap acts. The riser pipe cover and valve flap are connected to one another by a linkage. This device However, it is comparatively expensive and can only be effective if the filling car is already removed before it is removed the oven doors and the subsequent squeezing out of the coke cake to refill the coking oven.

The invention has now set itself the task of creating a device that reliably and with relatively simple means Actuation of riser pipe cover and valve flap caused in the order described above, regardless of the Position of coke oven operating machines is.

The device according to the invention is characterized by a hydraulically, pneumatically or electrically acting adjustment device,

one end of it at the riser pipe de disgust and the other end engages on the valve flap, the torque required to open the riser pipe cover is selected to be greater than that for Closing the valve flap and the torque required to open the valve flap are again greater than that for closing of the riser pipe cover is.

The proposed actuator ensures a safe open or close the riser pipe cover and valve flap in the required order. Because she is not working on a coke oven machine is arranged, can, if necessary, at any time and at each coking furnace, an actuation of the shut-off devices take place.

The actuation can be included in the automation of the coking plant, i.e. it can be controlled by a switchgear, for example in the coal tower according to the program, "as well as in the semi-automatic actuation by the shut-off devices Switching elements can be carried out either from the feeder car or from the top of the furnace.

Finally, the invention also provides that the adjustment device on the riser pipe cover and / or on the valve flap via an elongated hole is attached. As a result, a shock effect is achieved which is useful for loosening a shut-off element that may have stuck together.

The invention is illustrated in the drawing, for example. Therein, 1 denotes the riser pipe, the lower end of which is not shown here in the upper corner of a coking furnace reaches in. The riser pipe has above a bend consisting of two parts 2 and 3 screwed together, which into the Template 4 opens. A valve flap 5 is attached to the template on a shaft 6. This shaft sits outside the riser pipe elbow an actuating lever 7 and a counterweight 8.

On part 2 of the riser pipe elbow, the riser pipe cover 9, which is connected to the shaft 10, is provided at the top. With this Outside of the riser pipe elbow, the shaft is in turn an actuating lever 11 connected.

Between the valve flap 5 and riser tube de disgust 9 is an adjustment device 12 arranged suitable design, which is either hydraulically, pneumatically or electrically effective. In the present case, that is Housing 13 of the adjustment device attached to the actuating lever 7 of the valve flap, while the extendable actuating rod 14 with the operating lever 11 of the riser pipe cover is connected. This latter connection is made via an elongated hole 15 in order to start the movement to get a stoic effect.

The torques are selected by the design of the actuating levers 7 and 11 and by the counterweight 8 so that during actuation the shut-off device from the position shown in the position indicated by dash-dotted lines is first the housing 13 of the Adjusting device moves towards the riser pipe cover, because there is a larger one Torque is required. The valve flap 5 thus closes first, and only when it has come to rest, the rest of the way is used Hub de · Veretellgerätes to open the riser pipe cover. Of the The coking oven in question is now suspended from the template. The furnace is attached to the template in the reverse order.

Here, the actuating rod 14 is extended and closed as a result of the different torques first the riser pipe cover, and after this has come to rest, it forms the necessary supporting torque to open the valve flap when the actuating rod is extended further.
