Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for cleaning the lower part of a coke oven door.

The purpose of the present invention is to quickly and reliably clean the lower knife edge and seal plate of the door, which are heavily contaminated with tar and carbon, so that the door can be attached to the furnace mouth without gas leakage. It's about doing.

Conventionally, extruders and coke guide cars for course furnaces are equipped with a door cleaner, and each time the door is removed to open the furnace opening when extruding kiln coke, the door is placed opposite the door cleaner. The knife edge and seal plate have been cleaned by the door cleaner, but there was a problem in that it took time for the door cleaner to rotate around the entire circumference of the knife edge and seal plate.

In addition, the knife edge and seal plate parts were cleaned with a flat scraper, so
The problem was that the hard baked carbon could not be scraped off and cleaned by the scraper.

The present invention focuses on the fact that tar and carbon are concentrated in the lower part of the door, so the vacuum cleaner circulates only in this area to shorten the cleaning time, and uses a high-pressure water injection method. Even the strongly baked-on carbon particles were cleaned up by the explosion and self-destruction.

Examples will be described below with reference to the drawings.

Push machine and coke guide truck frame 10
A cart 1 that moves forward and backward toward the coke oven is loaded on top. 11, 11' are rails for advancing and retreating; 12,
12' is a wheel, 13 is an oil motor that moves the truck 1 forward and backward, 14 is a rotating screw shaft, and 15 is a wheel that is screwed onto the screw shaft 14 and is attached to the lower surface of the truck 1.

The reciprocating cart 1 is formed to be horizontally long, and traverse rails 16, 16' are provided thereon, on which the cart 2 for lateral movement is mounted. 17 and 17' are wheels, 18 is an oil motor, 19 is a rotating screw shaft, and 20 is a wheel that is screwed onto the screw shaft 19.

A rigid pillar 3 having a support 21 stands upright on the trolley 2, and a horizontal box part 22 is attached to the upper end of the rigid pillar 3.
and a rotating screw shaft 4 parallel to the front and back direction between the truck 2,
Install 4'. 23 is an oil motor, and 24 is a gear meshing mechanism.

A portion 25 with a high-pressure water jet nozzle 6 is attached to the front end of a support member 5 which is screwed onto the rotating screw shafts 4, 4' and moves up and down, so as to be adjustable in angle. A high pressure water supply hose (not shown) is connected to the connection port 26 of the member 25.
is installed.

When cleaning, move the cart 1 forward and insert the nozzle 6 into the knife edge 8 on one side of the removal door 7.
(Fig. 1), and operate the oil motor 23 while jetting high-pressure water to connect the gear meshing mechanism 24.
The support member 5 is lowered in the direction of the arrow by rotating the screw shafts 4 and 4' in the same direction via the , and when the nozzle 6 reaches the lower end of the knife edge 8, the lateral moving cart 2 is moved in the direction of the arrow, The knife edge 6 is again moved upward along the bend.

In this way, by moving the nozzle 6 in the direction of the arrow in Figure 1 while injecting high water pressure close to the knife edge 8 and seal plate 9, the attached carbon will explode and self-destruct, and the tar will flow down. , the knife edge and the seal plate will be cleaned thoroughly. Moreover, nozzle 6
Since it only goes around the lower part of the door 7, the cleaning time can be extremely shortened.

Thus, the present invention has the effect of providing a novel door vacuum cleaner.

Figure 1 is a front view showing the state in which cleaning has started, Figure 2
Figure 3 is the same side view, Figure 3 is the same plan view, 1 is a cart for forward and backward movement, 2 is a cart for lateral movement, 3 is a rigid shaft, 4,
4' is a rotating screw shaft, 5 is a support member, 6 is a high-pressure water jet nozzle, 7 is a door, 8 is a knife edge, and 9 is a seal plate.

Claims (1)

[Claims] 1 A truck 1 that moves back and forth toward the coke oven and a truck 2 that slides laterally on the truck 1 are loaded on the extruder and coke guide car, and the truck 2 is placed parallel to a rigid pillar 3 that stands upright on the truck 2. Two rotating screw shafts 4 and 4' are installed in the front and back direction, and a high-pressure water injection nozzle 6 is attached to the front end of a support member 5 that is screwed onto the screw shafts 4 and 4' and moves up and down. A device for cleaning the lower part of a coke oven door, characterized in that a nozzle 6 sprays high-pressure water onto a lower knife edge 8 and a seal plate 9 of a door 7 while rotating them facing each other for cleaning.
