Description

Coal removal device in the hopper {DEVICE FOR REMOVING ADHERED COAL IN HOPPER}

The present invention relates to an apparatus for removing coal deposits in a hopper capable of removing coals attached to an inside of a basis weight hopper before manufacturing coke produced in a coke oven.

In general, in the oven process, the basis weight chamber is a pre-step of loading the coal supplied from coal coal into the carbonization chamber using a loading car, and a certain amount of coal is weighted and transferred to the loading car during each operation.

At this time, due to the occurrence of a bottleneck at the bottom due to a structural problem of the basis weight hopper, coal stagnation occurs, and due to this coal stagnation problem, coal deposits in the hopper are generated.

In this way, when removing the coals generated in the hopper, dangerous manual work due to the narrow space is repeatedly performed and a large number of workers must be put in.

In addition, production delay due to excessive time in the coal removal operation, and target charging amount deviation occurs due to the charging amount hunting, and environmental pollution by opening the hopper inspection port during removal work, and the risk of safety accidents due to narrow work. There was a problem.

As one of the methods for removing the coal deposits in the hopper, a method using a magnetic hammer is known.

In the case of removing the coals by using a magnetic hammer, the hopper structure is cracked and cracked by hitting the hopper with the magnet hammer, and it is not possible to easily remove the coals from the hopper by indirect hits outside the hopper rather than by a direct hit inside the hopper. There was a problem.

An object of the present invention is to provide an apparatus for removing coal deposits in a hopper capable of effectively removing coals from the hopper without opening the hopper inspection port, and capable of removing coals from the hopper in all directions while preventing the hopper structure from being deformed. .
