Description

[Detailed description of the invention] Industrial application field This invention relates to a coke discharge device for a shaft oven type coke dry extinguishing equipment.

Prior Art As shown in Fig. 1, the conventional discharge device of a coke dry extinguishing system drains the coke inside the cooling chamber 1 into a two-stage upper and lower chamber equipped with seal gates 21 and 31 to ensure sealing performance with the outside air. It is configured to discharge onto a conveyor 5 via intermediate hoppers 2 and 3.

The coke discharge operation in such a conventional device is performed as follows.

By alternately opening and closing cut gates 11 and 12 installed opposite to each other at the lower part of the cooling chamber 1, a certain amount of coke (approximately 2 to 3 tons) is cut into an upper intermediate hopper 2. Next, the seal gate 21 at the bottom of the upper intermediate hopper 2 is opened, and a certain amount of coke is transferred to the lower intermediate hopper 3. Next, after waiting for the seal gate 21 to close, the seal gate 31 at the bottom of the lower intermediate hopper 3 opens.
A certain amount of coke is discharged onto a conveyor 5 via a wharf 4. Thereafter, the series of coke discharge operations is repeated after waiting for the seal gate 31 to close.

In this way, in conventional discharge devices, coke is cut out from the chamber intermittently, and all of the coke in the chamber is cut out in a short period of time each time. The turbulence of the cooling gas flow makes the cooling characteristics of the chamber unstable, and the sudden fall of coke promotes coke pulverization, resulting in a decrease in lump coke yield.
There was a problem in that the cost of dust recovery equipment had to increase.

Purpose of the invention An object of the present invention is to solve the problems of the conventional intermittent cutting method and to provide a device that continuously discharges coke from a cooling chamber.

The gist of the present invention is to provide a system for discharging coke in a cooling chamber of a shift oven-type coke dry extinguishing system onto a conveyor via an upper and lower intermediate hopper having a sealing mechanism with the outside air. A continuous cutting device is installed at the chamber cutting port to continuously and forcibly cut out the coke in the cooling chamber and supply it to the upper intermediate hopper. This is a coke discharge device for a coke dry extinguishing equipment, characterized in that a cut damper for stopping the coke is installed at the entrance of the upper intermediate hopper.

In particular, in this invention, the function of the upper and lower intermediate hoppers with a sealing mechanism with the outside air of the conventional device is basically unchanged, and in order to continuously cut coke from the cooling chamber, the function of the intermediate hopper is changed from the cooling chamber. A continuous cutting device is installed between the upper intermediate hopper, and a cut damper is installed at the inlet of the intermediate hopper to prevent coke from being swallowed when the seal gate of the upper intermediate hopper is closed. It has the characteristics of

The present invention will be described in detail below based on examples.

FIG. 2 is a diagram showing the configuration of an embodiment of the present invention. In the figure, reference numeral 6 denotes a vibrating feeder as a continuous cutting device provided at the cutting opening of the cooling chamber 1, and the coke continuously cut out by the vibrating feeder 6 is temporarily stored in an intermediate hopper in the upper stage. When the coke level in the upper intermediate hopper 20 reaches a certain level, the seal gate 21 is opened and the coke is transferred to the lower intermediate hopper 30. The coke in the lower intermediate hopper 30 is
After waiting for the seal gate 21 of the upper intermediate hopper 20 to close, the seal gate 31 at the bottom of the lower intermediate hopper is opened, and the food is supplied to the bunker 7, and uniformly and continuously discharged onto the conveyor 5 by the vibrating feeder. Note that 71 is a flow rate adjustment gate provided inside the bunker 7. During this series of coke discharge operations, when the seal gate 21 of the upper intermediate hopper 20 is closed, a seal gate is provided at the inlet of the upper intermediate hopper 20 in order to prevent the coke continuously cut out from the vibrating feeder 6 from being trapped. The cut damper 22 is operated to temporarily stop the flow of coke. In addition, in this embodiment, a plurality of flow rate adjustment rods 13 are installed at the bottom of the cooling chamber,
By adjusting the insertion length of the flow rate adjusting rod 13 into the chamber, coke is allowed to fall uniformly within the chamber.

Effects of the invention Since the device of the present invention has the above-mentioned configuration, the coke inside the cooling chamber can be continuously discharged while ensuring a seal with the outside air like the conventional device. It has the excellent effect of stably maintaining the cooling characteristics of coke and minimizing the pulverization of coke.
