Generally, cokes used in steel mills are a kind of coal used as a means of securing air permeability along with the role of a heat source and a reducing agent in a blast furnace. Such coke is produced by a coke oven at a coke plant.

In the production process of coke, first, the charging car located in the upper part of the coke oven charges cohesive coal into the carbonization chamber of the coke oven at regular intervals, and the coal charged into the carbonization chamber of the coke oven is sealed. After indirect heating at about 1,300 ° C. in, after about 18 hours of distillation, it is dried into red coke and extruded to the outside of the coke oven by the ram of the extruder. After being guided by and loaded into the bucket, it is transported for later processing.

Meanwhile, when the raw material coal is charged into the carbonization chamber of the coke oven, the leveling operation is performed so that the upper portion of the coal charged into the coke oven is flattened by the leveler beam mounted on the leveler device of the extruder. do.

Such a leveler beam (not shown) is inserted into the carbonization chamber 100 through the leveler door 200 installed at one side of the carbonization chamber 100 of the coke oven, as shown in FIG. Leveling of the charged coal is performed.

However, the above conventional technologies have the following problems.

In the conventional leveling operation, accumulated coal A, which is coal accumulated inside the leveler door, is formed, and a gap occurs when the leveler door is closed, thereby causing a problem in that polluted gas is leaked during the dry distillation operation.

In addition, there is a problem that the accumulated coal is burned during the dry distillation operation to generate a high temperature flame to damage the leveler door.

Therefore, it is urgent to develop an apparatus for quickly removing accumulated coal, which is coal accumulated inside the leveler door of the coke oven.

Therefore, the accumulated coal inside the leveler door can be more completely removed.

The air injection unit 70 is installed in the horizontal contact tube 40, by injecting the vortex-like air into the leveler door through the horizontal contact tube 40 by the brush unit 60 The dust generated when the accumulated coal is removed is pushed into the carbonization chamber so as not to be discharged to the outside, and at the same time, the carbonization chamber serves to prevent the polluting gas from being discharged to the outside through the leveler door (FIGS. 6).

The air injection unit 70 is attached to the circular tube 71 provided to surround the outer surface of the horizontal contact tube 40, the one end is in communication with the circular tube 71 and the other end is the horizontal contact tube A plurality of vortex injection nozzles 72 provided through the inside of the 40 and obliquely disposed to one side in a state of facing forward to form a vortex, and an air supply pipe connected to one end of the circular tube 71 in communication with each other ( 73, an air pump 74 installed at an end of the air supply pipe 73, and a first open / close valve 75 installed on a conduit of the air supply pipe 73.

When the external air is sucked by the driving of the air pump 74 and injected into the air supply pipe 73, the air injection unit 70 opens the air supply pipe 73 by the first opening / closing valve 75. While high pressure air is injected into the circular tube 71 through the air supply pipe 73, the injected high pressure air is injected through the vortex injection nozzle 72 while the inner side of the horizontal contact tube 40 is closed. It is injected into the inside of the leveler door in the form of a vortex, so that dust and polluted gas is not discharged to the outside of the leveler door by the vortex-type injected air flows into the inside of the carbonization chamber.

The air injection unit 70 also serves to cleanly remove even fine accumulated coal remaining in the leveler door by vortex type air injection. Here, the air pump 74 is a known air compression pump that sucks the outside air and discharges it in a high pressure state. The first on-off valve 75 is a known electronic valve that opens or closes the conduit of the air supply pipe 73.

The water injection unit 70a is connected to the air supply pipe (73) (71a), the reservoir (72a) is connected to the end of the connection pipe (71a) and the water is stored, and the reservoir (72a) A water pump 73a installed on the conduit of the connection pipe 71a forward and an auxiliary opening / closing valve 74a installed on the conduit of the connection pipe 71a forward of the water pump 73a. do.

The water injection unit 70a injects water from the reservoir 72a into the air supply pipe 73 through the connection pipe 71a by driving the water pump 73a and through the air supply pipe 73. The water is supplied to the circular tube 71 to inject water toward the brush part 60 through the vortex injection nozzle 72 to the inside of the horizontal contact tube 40.

As such, when water is sprayed onto the horizontal contact tube 40 and the brush part 60 by the water spraying part 70a, the brush is washed while the inside of the horizontal contact tube 40 and the brush part 60 are simultaneously washed. It is possible to quickly reduce the dust generated during the operation of the unit 60. Since the water is supplied through the air supply pipe 73, the water may be mixed with the high pressure air and sprayed through the vortex injection nozzle 72.

Here, the auxiliary opening and closing valve 74a is a known electronic valve that opens or closes the conduit of the connecting pipe 71a.

The scraper 80 is attached to the upper inner surface of the front end of the horizontal contact tube 40 and the tooth 81 is formed at the bottom, and removes foreign matter adhering to the cylindrical brush 62 of the brush part 60. In order to provide a portion where the cylindrical brush 62 of the brush part 60 is scraped. That is, the cylindrical brush 62 is rotated by the rotary motor while being reciprocated back and forth by the horizontal cylinder 51 while being positioned in the scraper 80, and foreign matter such as xanthan that is deposited on the cylindrical brush 62. This can be removed while scraping smoothly.
