JPS5930884A - Leveling mouthpiece in coke oven door and sweeping equipment for small lid on the mouthpiece - Google Patents

Abstract

PURPOSE:To efficiently remove the carbon deposits attached to titled part, by revolving a pressurized-water injection nozzle facing toward the front face of titled part, etc. while injecting water, during the leveling mouthpiece is in an opened state, by means of a specific mechanism. CONSTITUTION:The horizontal fram 3 on an extruder 1 is equipped with a long-sided frame 6 capable of moving back and forth, while a truck 13 movable in the transverse direction is mounted on the frame 6. Also, while the vertical-moving device of the truck 13 is equipped with an apparatus 25 connected to the pressurized-water feed pipe 26 so that the apparatus 25 can move vertically, a pressurized-water injection nozzle 28 is provided to the front end of the apparatus 25. While the leveling mouthpiece 31 in the coke oven door 30 is in an opened state, the frame 6 is allowed to advance by operating the motor 8 to make the injection nozzle 28 face in close proximity toward the leveling mouthpiece-forming frame 31', followed by revolving said nozzle 28 by operating both motors 23 and 14, along the front face of the mouthpiece 31, the knife edge of the small lid 32, and their peripheries, while feeding pressurized water through the feed pipe 25 to said nozzle 28 to carry out injection, thus accomplishing the objective sweeping.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device for the leveling spout and the leveling spout small lid of a coke oven door. The knife edge of the front surface and small lid and its surroundings are resistant to adhesion and can be efficiently cleaned by direct rotation of the high-pressure water jet nozzle.

The features of the present invention are that a horizontal frame is provided on the extruder that runs on the extrusion side of a coke oven, that a horizontally long frame that moves back and forth in the front and rear directions is provided on the horizontal frame, and that a cart that moves laterally is mounted on the horizontally long frame. A device connected to the pressure water supply pipe is attached to the vertical movement mechanism provided on the trolley so as to move up and down, and a pressure water injection nozzle is provided at the front end of the device, and the door with the injection nozzle opened is installed in the same position. The purpose is to clean the front end surface of the spout, the knife edge of the small lid, and the surrounding area by turning the knife directly around the area.

With the above configuration, the pressure water injection nozzle can be moved up and down, back and forth, and left and right by the movement of the oblong frame and the lateral movement of the cart, and can be opened by performing a combination of these movement operations. It can be rotated directly facing the front end surface of the lore leveling port and the side part of the small lid that is brought forward and opened, keeping a close distance. In particular, since it can follow each corner that bends at 90 degrees and follow it around, each corner can also be cleaned thoroughly.

An embodiment will be described below. A frame body 2 is installed on a pressing machine 1, and a horizontal frame 6 is laid on the frame body 2. Both sides of the horizontal frame 3 have 1 chevron, 4 fCV-rules,
The horizontal frame 6 is mounted on the rail 4.4' so that the horizontal frame 6 can move forward and backward in the front and rear directions. It is a rotating shaft installed in the direction, and a thread (not shown in the drawing) is carved on the outer surface. 8 is a motor for rotation, and 9. is a screwing member installed under the plywood 10 under the horizontally long frame 6. It has a screw hole and is screwed onto the rotating shaft, so that when the rotating shaft 71k is rotated by a motor, for example, in the right direction, the horizontally elongated frame 6't moves forward, and when it is rotated to the left, it moves backward.

Reference numeral 11.11' denotes a chevron-shaped rail constituting the horizontally long frame 6. Wheels 12 and 12' are fitted onto the rails 11 and 11', and the cart 13 is mounted thereon. 14 is a rotation motor, 1
5 is a rotating shaft with threads carved on the outer surface in the same manner as above; 16
is a threaded member that is screwed onto the rotating shaft 15. When the rotating shaft 15'k is rotated by the motor 14, for example, to the right, the trolley 13 moves to the right, and when it rotates to the left, it moves to the left. There is.

A column 17 is installed vertically on the truck 13, and two rotating shafts 20 and 20' are vertically installed between the front sides of the mounting plate 18 fixed to both sides of the upper end of the column 17 and the gear box 19 of the truck 13. ,
The rotating shafts 20, 20' are fully threaded on their outer surfaces. 2
1.21' is the bearing %22, 22' is the rotating shaft 20, 20
The gear %23 that fits into the motor is the drive gear inserted into the motor shaft, and the gear 025 that meshes with the gears 22 and 22' is a device that connects to the pressure water supply pipe 26, which is attached to the front and rear sides of 1. Screwing members 27, 27't-with rotating shaft 20
．． The rotating shaft 20.20''e is screwed onto the motor 20' and rotates with a gear so that, for example, when it is rotated in the forward direction, one instrument 25 moves downward, and when it is rotated in the reverse direction, it is moved upward.

A is a pressure water injection nozzle attached to the front of the instrument 25.

Leveling wheel 3 of door 30 attached to kiln mouth 29 of coke oven
1 is opened, the horizontal frame 3 is moved forward by the operation of the motor 8, the pressure water injection nozzle 28 is brought close to and directly in front of the leveling mouth-shaped bottom frame 31', and then the pressure water supply pipe 5 is opened. While supplying and injecting pressurized water to the nozzle, the motor 2.3 for vertical movement and the motor 14 for lateral movement are operated in forward and reverse directions to orbit in front of the forming frame 31'.
1', the nozzle 28 is moved directly in front of the opened small lid 32, and the knife edge 33 and its surrounding area are thoroughly cleaned using circular motion similar to that of a ship. That's what I do.

When the cleaning is completely finished, move the horizontal frame 6 back and remove the nozzle 28.
The small lid 32 is moved away from the front of the small lid 32, and the small lid 32 is made rotatable to completely close the leveling port 3.

The front surface of the leveling mouth-shaped bottom frame 31' and the knife edge 3 of the small lid 32
3 and its surroundings have been thoroughly cleaned, so they are in close contact and no gas leakage occurs.

In addition, in this example, everything from the forward and backward movement of the horizontally long frame 6 to the vertical movement of the nozzle was constructed by the forward and reverse rotation of rotating shafts and screwing members that are screwed into these rotating shafts. It is also possible to use sounds such as cylinders and gear mechanisms.

The present invention provides a screwing member 27 on two sides of the instrument 260, front and back.
27'? Since it is attached and screwed to the rotating shaft, the device 26 can be moved up and down while always maintaining a horizontal state, and the exposed front surface of the device 26 can be used to attach a relatively large pressure water injection nozzle 28t. can.

In this way, the present invention has the effect of providing an apparatus for efficiently cleaning the knife edge of the door opening and small lid, and the entire surrounding area.
