Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
The heatingup of coke oven battery horizontal road brickwork joint existed to solve prior art is difficult to the problem sealed, the invention provides a kind of heatingup of coke oven battery horizontal road brickwork joint tightness system, as shown in Figure 1, tightness system embodiment provided by the invention comprises: sealing member 8, first operating stick 2, recycling bin 9, second operating stick 1, support, the first mounting block 4, second mounting block 3.
In order to structure, the function of description sealing device embodiment that more illustrate, Fig. 2 shows the structure of the refractory brick 24 piled up in oven top of coke oven 20 and the horizontal road of baker wherein 23, the horizontal road 23 of baker etc.As shown in Figure 1 and Figure 2, sealing member 8 is for being placed in flue, and such as flue 21, flue 22, formed with the sidewall of flue and seal, and makes to seal the slip 30 of brickwork joint and can inject, to be collected at above sealing member 8 and to infiltrate brickwork joint 240.In order to simplify the structure of sealing member 8, and obtain better sealing effectiveness, sealing member 8 is in column, and upper surface periphery is provided with the first sealing-ring 7.The sidewall of flue 21 grade more pressed close to by first sealing-ring 7, to increase the sealing effectiveness between the sidewall such as sealing member 8 and flue 21, prevents slip 30 from falling into below sealing member 8.In order to strengthen the stopping property between the sidewalls such as the first sealing-ring 7 and flue 21, during application, between the sidewalls such as the first sealing-ring 7 and flue 21, being filled with litaflex 41, namely using litaflex 41 to carry out encapsulation process.
The lower end of the first operating stick 2 is connected to the upper surface of sealing member 8, and for operating sealing member 8, such as the upper end of hand-held first operating stick 2, can move up and down sealing member 8 in outsides such as flues 21.
Recycling bin 9 is positioned at below sealing member 8, opening upwards, infiltrates the remaining slip 30 of brickwork joint 240 for reclaiming.Preferably, as the first sealing-ring 7, the lower end periphery of recycling bin 9 is provided with the second sealing-ring 10, to increase the sealing effectiveness between the sidewall such as recycling bin 9 and flue 21, in order to strengthen the stopping property between the sidewalls such as the second sealing-ring 10 and flue 21, during application, between the sidewalls such as the second sealing-ring 10 and flue 21, be filled with litaflex 41, namely use litaflex 41 to carry out encapsulation process, prevent slip from falling into firing system.First operating stick 2 of the present embodiment is in tubular, second operating stick 1 is connected to the bottom center of recycling bin 9 through the first operating stick 2, whereby, the second operating stick 1 can pass sealing member 8, first operating stick 2 up or down, when handling in the second operating stick 1 upper end, recycling bin 9 can be moved up and down.
Support preferably includes cylinder 6 and multiple leg 61, and cylinder 6 can be sheathed on the first operating stick 2 up or down.The upper end of multiple leg 61 is distributed in the outer side wall of cylinder 6, and lower end, then for being supported on oven top of coke oven, is that the first operating stick 2 provides support.More preferably, leg 61 is curved.In other embodiments, leg also can be tabular component.Apparently, the present invention is not limited thereto, and any support can fixing the first operating stick 2, second operating stick 1 all can act on support and use.
First mounting block 4 is connected on the first operating stick 2, for fixing the first operating stick 2 in support.Preferably, the first mounting block 4 is a bolt, and the free end of this bolt passes the first operating stick 2 of sidewall sensing cylinder 6 inside of cylinder 6.After relative position between the first operating stick 2, cylinder 6 is determined, tighten the first mounting block 4, the free end of the first mounting block 4 is tightly supported on the first operating stick 2, the position of the first operating stick 2 can be fixed.
Second mounting block 3 is connected to the second operating stick 1, for fixing the second operating stick 1 in the first operating stick 2.Preferably, second mounting block 3 is also a bolt, the free end of this bolt points to the second operating stick 1 of the first operating stick 2 inside through the sidewall of the first operating stick 2, after relative position between the first operating stick 2, second operating stick 1 is determined, tighten the second mounting block 3, namely can fix the position between the second operating stick 1 and the first operating stick 2.
For the ease of injecting slip 30 to flue 21 grade, the present embodiment also comprises slip injection tube 5, and it is roughly in funnel-shaped structure, and the length direction along the first operating stick 2 extends near above sealing member 8, can inject slip 30 above sealing member 8.More preferably, slip injection tube 5 is fixed on the first operating stick 2, integral structure convenient operation, movement.
When application the present embodiment carries out the sealing operation of brickwork joint 240, as shown in Figure 2, two covers tightness system embodiment provided by the invention is placed through respectively coke oven vertical flame path 21 that the horizontal road 23 of baker is communicated with, flue 22 (in order to simplify accompanying drawing and description, only the present embodiment in flue 21 marked in detail and describe) in, the position of recycling bin 9 is wanted significantly lower than the height in the horizontal road 23 of baker.Distance between the tightness system (the first operating stick in Fig. 2) that the sealing brick piled up in the horizontal road of baker and the present embodiment provide is greater than the distance between tightness system (the first operating stick in Fig. 2) that flue sidewall and the present embodiment provide.
Then, litaflex 42 to be filled between recycling bin 9 and flue 21 in gap, unclamp the second mounting block 3 and the first mounting block 4, the leg 61 of support is made to fall within above oven top of coke oven 20, whereabouts sealing member 8, sealing member 8 bottom is docked with recycling bin 9 top, and the first sealing-ring 7 is in the flue 21 of bottom, baker horizontal road 23, uses litaflex 41 encapsulation process between the first sealing-ring 7 and flue 21.
Screw the second mounting block 3 and the first mounting block 4.Aforesaid operations is repeated to the tightness system embodiment in flue 22.
Then, grouting slip 30 is injected position, baker horizontal road 23 by slip injection tube 5, slip 30 enters in the brickwork joint 240 of the refractory brick 24 in the horizontal road 23 of baker under gravity, realizes encapsulation process.
After encapsulation process terminates, unclamp the second mounting block 3 and the first mounting block 4, when maintenance second operating stick 1 invariant position, mention the first operating stick 2 and sealing member 8, make unnecessary slip 30 enter recycling bin 9.
After recovery terminates, the present embodiment is proposed coke oven vertical flame path 21,22, complete position, baker horizontal road 23 encapsulation process of coke oven vertical flame path 21,22.
In sum, the present invention can use two covering devices to carry out encapsulation process to the horizontal road of baker simultaneously, and what realize position, baker horizontal road seals improvement fast and effectively.Further, tightness system of the present invention also comprises slip recycling bin, is collected by slip unnecessary in seal process, prevents slip from falling into firing system, affects the normal heating of coke oven.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
