SU27623A1 - Automatic shutter to the planning hatch of coke oven doors - Google Patents

Description

The proposed closure to the planning hatch of the doors of coke ovens operates automatically and does not require an individual for its service, which is necessary for commonly used closures.

In the schematic drawing of FIG. I represents the position of the proposed automatic shutter during the movement of ililir into the furnace; FIG. 2 is the same when reverse movement plan.

Opening and closing of the hatch with the proposed shutter is as follows.

The coking pin is equipped with a stubborn finger 7; a suitably curved sheet goes upwards from the shutter lid 2 in an inclined position, guiding J. The lid 2 and the guiding 3 are rigidly interconnected and rotate on a common hinge 4. When the plane moves forward, the thrust finger directed at a certain angle to the plan lying on the front support 5, resting against the guide 5, lifts the cover 2 to such a height. With the further movement of the plan, the last one, the finger / with the guide 3 lies on the plan.

The finger / released from the guide 3 and carried into the furnace by the planned grip, resting against the lid 2, tilts back and rests on the support 6 on the plan,

Thus, by moving forward, the planner opens a hatch for himself to enter the furnace.

On the return path of the plan, from the oven, slides over it, the lid 2 with the protrusion 7 which is on it engages the protrusion 8 on the finger /, as a result of which the finger / is forced to rise to a certain height during further movement of the plan from the oven; from engaging with the cover 2, fall onto the fixed frame P of the coke-pushing device, which returns it to its initial inclined position on the front support 5.

Upon leaving the plan from the furnace, the lid 2 under the action of its gravity falls down and tightly slam the hatch.

The subject of the patent.

An automatic shutter to the planning hatch of the doors of coke ovens, characterized in that for the purpose of automatically opening and closing the planned hatch, the lid 2 of the hatch at the top is provided with guide 1, 5, and the plan of the coking pivot is connected to it with a support finger /, supports 5 and 6 to frame 9.
