Description

The present invention relates to a furnace port cleaner and a furnace port cleaning method for removing a deposit formed on a furnace port of a coke oven.

In a coke oven, the gas generated during operation is cooled near the furnace port, and the tar component in the gas becomes tar, and the inner surface of the furnace port, the sheet surface of the furnace port (on the outer periphery of the furnace port, To adhere to the knife edge provided on the inner surface of the furnace cover that covers the surface of the furnace lid to form a deposit, and the deposit grows with the passage of the coke oven operating time (the deposit deposition range is expanded, Thickness increases). The dust generated when red hot coke is discharged from the carbonization chamber or when coal is charged into the carbonization chamber accumulates on the deposit, thereby further accelerating the growth of the deposit. For this reason, if deposits formed on the inner peripheral surface of the furnace port and the furnace port sheet surface grow, when the furnace cover is attached to the furnace port, the knife edge of the furnace cover and the furnace port sheet surface Adhesion becomes insufficient, gas leakage from the carbonization chamber becomes noticeable, and air flows into the carbonization chamber, which impedes the operation of the coke oven.

Therefore, for example, in Patent Document 1, as shown in FIG. 7, a coke oven working vehicle (also referred to as a coke oven moving machine, not shown), specifically, an extrudate that extrudes red hot coke from a carbonization chamber or a carbonization chamber is extruded. The sheet surface scraper mounting lifting frame 101 and the sheet surface scraper mounting lifting frame 101 which are loaded on a guide car for transporting the generated red hot coke to a fire extinguisher and are disposed to face the furnace opening sheet surface 100 with a gap. A plurality of inclined attachment arms 103 whose ends are attached via pins 102, scrapers 104 attached to the tip portions of the inclination attachment arms 103, and the front side of the inclination attachment arms 103 are directed to the furnace port seat surface 100. A sheet cleaner 107 having springs 105 and 106 for rotating the scraper 104 and pressing the tip of the scraper 104 against the furnace port sheet surface 100 has been proposed. Reference numerals 108 and 109 are stoppers for maintaining the initial rotation angle of the inclined mounting arm 103 at a constant value, and reference numeral 110 is a bearing for the pin 102. In a state where the tip of each scraper 104 is pressure-bonded to the furnace opening sheet surface 100, the sheet surface scraper mounting lifting frame 101 is moved up and down with a certain stroke so that the deposits on the furnace opening sheet surface 100 are adhered to each scraper 104. The tip is scraped off, and the deposits on the furnace opening sheet surface 100 are removed.

They are set so as to be in contact with the inner surfaces of the left and right wall members 80 and 81, respectively.

By configuring the furnace port 12 and the inner surface removing portion 23 as described above, when the movable carriage 13 of the furnace port cleaner 10 is advanced toward the furnace port 12, for example, as shown in FIG. When the center position in the left-right direction of the means 53 is shifted to the left with respect to the center position in the left-right direction of the furnace port 12, the tip portion of the left guide guide 82 contacts the tip portion on the inner surface side of the left wall member 80. Accordingly, a right reaction force is applied from the left wall member 80 to the left guide guide 82, and the right reaction force acts on the mounting member 54 via the left guide guide 82. As a result, the piece 63 of the aligning means 55 connected to the attachment member 54 moves to the right side while compressing the spring 65, and the attachment member 54 also moves to the right side. Then, while the left guide guide 82 advances while contacting the front portion on the inner surface side of the left wall member 80 as the movable carriage 13 advances, a right reaction force is applied to the attachment member 54 via the left guide guide 82. The mounting member 54 continues to move to the right, and the tip of the left opening side scraper 78 of the second inner surface removing means 53 is moved to the left side metal of the furnace mouthpiece 45 as shown in FIG. The tip of the surface 46 can be contacted.

When the movable carriage 13 further advances in a state where the tip of the left-opening side scraper 78 of the second inner surface removing means 53 is in contact with the tip of the left side metal surface 46 of the furnace mouthpiece 45, the left wall member 80 is moved forward. A right reaction force is applied to the left guide guide 82 from the left side metal surface 46 and a right reaction force is applied to the tip of the left opening side scraper 78 from the left side metal surface 46, and these right reaction forces act on the mounting member 54. . As a result, the piece 63 of the aligning means 55 connected to the attachment member 54 moves to the right side while compressing the spring 65, and the attachment member 54 also moves to the right side. Then, as the movable carriage 13 advances, the left guide guide 82 is attached while the left wall guide member 80 and the left opening side scraper 78 are in contact with the left side metal surface 46 while moving forward. Since the right reaction force continues to act on the member 54 and the mounting member 54 continues to move to the right side, as shown in FIG. 5, the left-opening side scraper 78 of the second inner surface removing means 53 is moved to the left. It can be inserted into the furnace mouthpiece 45 in contact with the side metal surface 46.

When the movable carriage 13 further advances in a state where the left opening side scraper 78 of the second inner surface removing means 53 is in contact with the left side metal surface 46, the left and right opening side scraper 78 of the second inner surface removing means 53. , 79 enters the left opening side scraper 78 between the left and right opening side surfaces 51 and 52 constituting the opening 50 of the furnace shell 49 in a state where the left opening side surface scraper 78 is in contact with the left opening side surface 51. The left and right arm members 72 and 73 of the first inner surface removing means 48 are biased by the spring mechanism 71 in a direction in which the angle between the left and right arm members 72 and 73 decreases, so The surface scrapers 68 and 69 do not contact the left and right side metal surfaces 46 and 47. Therefore, a right direction reaction force is applied from the left wall member 80 to the left guide guide 82, and a right direction reaction force is applied from the left opening side surface 51 to the left opening side surface scraper 78. These right direction reaction forces are applied to the mounting member 54. Act on.

As a result, the piece 63 of the aligning means 55 connected to the attachment member 54 moves to the right side while compressing the spring 65, and the attachment member 54 also moves to the right side. Then, as the movable carriage 13 advances, the left guide guide 82 advances while contacting the left opening side 51 and the left opening side scraper 78 while contacting the left opening side 51. The right reaction force continues to act on 54, and the mounting member 54 continues to move to the right. As a result, as shown in FIG. 6, the insertion stoppers 74 respectively provided on the left and right arm members 72 and 73 of the first inner surface removal means 48 abut on the left and right side sheet portions 17 and 18, The left and right metal surface scrapers 68 and 69 are inserted between the left and right side metal surfaces 46 and 47 in a non-contact state, respectively. On the other hand, the left and right opening side surface scrapers 78 and 79 of the second inner surface removing means 53 are arranged between the left and right opening side surfaces 51 and 52 in a state where the left opening side surface scraper 78 is in contact with the left opening side surface 51.
