Description

TECHNICAL FIELD [0001] The present invention relates to a chute assembly for door cleaner having a retainer foreign substance removing function.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door cleaner suit assembly having a retainer foreign substance removing function. More particularly, the present invention relates to a door cleaner assembly for removing foreign substances such as tar, To a chute assembly.

The coal charged in the loading car 10 is charged into the carbonization chamber 30 of the coke oven 20 and the both sides of the carbonization chamber 30 are introduced into the coke oven door 30 as shown in Fig. (70), followed by heating and carburizing process. Thereafter, the coke oven door 70 is opened and then the coke in the carbonization chamber 30 is moved to the discharge truck 50 by using the extruded car 60.

At this time, foreign substances such as tar generated during coke production are attached to the coke oven door 70, which seals both sides of the coke oven 20, and the retainer 90, which supports the door refractory 80, When the coke oven door 70 is reinstalled, the carbonization chamber 30 and the coke oven door 70 are not completely sealed, causing the gas to leak.

Therefore, in order to prevent such a phenomenon, the door cleaner 200 is automatically operated to clean the coke oven door 70 before the coke oven door 70 is detached by the door detacher and then the extrusion operation is performed.

As shown in FIG. 2, the door cleaner 200 is roughly divided into a foreign substance removing unit 600 for removing foreign substances from the coke oven door 70, and a chute 300 for loading and discharging falling foreign substances.

The foreign matter loaded on the chute 300 is manually discharged from the chute 300 and discharged to the chain conveyor by a worker using a cleaning tool every day. However, there is a risk that safety accidents such as fire and collision are always present due to scattered dust during the manual cleaning, and there are problems such as waste of manpower and lower productivity due to input of workers.

In order to solve such a problem, the conventional automatic door cleaning device (Registration Practical Utility Model No. 20-0257802) and Carbonization Door Cleaner Scrap Removal Device (Patent Document 10-2003-0041537) Lt; / RTI >

In the conventional "automatic cleaning device for door cleaner suits " (Registration Utility Model No. 20-0257802), when a tar or a knocked coke is to be solidified or accumulated on a chute entrance side, the cylinder moves the shaft, As the spring compresses, the scraper is pushed forward, causing the tar or the knocked coke to fall to the belt conveyor.

At this time, the scraper rotates together with the rotation of the rotating body, while the spring pushes the scraper downward, and the rotating body rotates around the installed shaft through the supporting frame. However, the turning radius of the scraper is controlled by the bar when the turning radius of the scraper becomes 90 ° -100 ° or more, and then the water is sprayed from the spray nozzle and the residue in the chute is cleaned.

Further, in the conventional "apparatus for scrap removal of carburized seal cleaner " (Patent Document 10-2003-0041537), in order to extrude a coke obtained by charging the coke charged in the carbonization chamber for a certain period of time, When the door cleaner approaches the carbonization chamber door and scrapes such as tar and carbon blocks adhered to both sides of the upper, lower, left, and right sides are removed by scraping off the scrap after removing the carbonization chamber door, And is dropped and deposited into the disposed scrap collecting box.

The door cleaning operation is completed, the door cleaner is moved back to the initial position, and the control circuit of the controller is operated by the sensing signal of the limit switch for sensing the operation of the door cleaner, so that the fire extinguishing pump is operated to supply fire extinguishing water to the fire extinguishing water supply line When a large amount of fire extinguishing water is sprayed through the water spray nozzle of the water spray line, water is sprayed on the scrap collected in the scrap collection box.

Accordingly, even if the red coke falls into the scrap collecting box, the scrap is ignited to generate a fire or to prevent dust and gas from being generated.

Further, the water spray through the water spray nozzle is performed for a predetermined time set by the timer, and then the water spray is stopped by shutting off the valve member of the spray water line. Subsequently, when the rod end of the actuating cylinder is advanced forward, the rear end of the actuating cylinder is connected to the hinge pin of the fixed bracket provided on the floor surface.

The connecting rod of the rod end is assembled to the connecting hole of the guiding block integrally mounted on the lower surface of the scrap collecting box and the upper and lower moving wheels assembled on both left and right sides of the scrap collecting box are guided by inclined rails And the horizontal rail, the scrap collecting box is switched from a horizontal state for scrap collection to a vertical state for scrap discharge during the maximum advancing operation of the operating cylinder.

Accordingly, the scrap collected in the scrap collecting box vertically converted is discharged to the side of the spillage coke conveyor installed in the vicinity of the scrap collecting box, and the scrap discharged therefrom is transferred to the nacoke hopper and reused in the sintering plant, The scrap collecting box is switched from the vertical state to the horizontal state by the backward return operation of the operating cylinder according to the control signal of the controller so as to collect the scrap falling off during the door cleaning operation.

However, in manufacturing a coke, a conventional "automatic cleaning device for a door cleaner suit (registered trademark model 20-0257802)" merely has a function of loading and discharging a falling foreign object without the function of preventing the occurrence of dust, Dust occurred.

Further, the "apparatus for removing scrap of carburized seal door cleaner " (Patent Document 10-2003-0041537) also has a similar function, and since there is no function of cleaning the retainer located at the lower end of the coke oven door, There is a problem that the productivity is reduced and the cost is increased by tightening the door cleaner.
