本考案は、高炉、キユーポラ、竪形石灰焼成炉
等の大形工業炉における炉壁の損耗部を熱間補修
する際の耐火物吹付用ノズル体の釣支装置に関す
るものである。[Detailed description of the invention] (Technical field) The present invention is a nozzle body for spraying refractories when hot repairing damaged parts of furnace walls in large industrial furnaces such as blast furnaces, cupolas, and vertical lime kilns. This relates to a fishing support device.
(従来技術)
上記のような大形工業炉において、炉壁の耐火
物が部分的に脱落するなど損耗した場合、炉を完
全に停止し、温度が下つた後に作業員が炉内に入
つて補修するのでは、温度が下る間の待時間が長

つて、炉の温度を下げずに、炉の側壁上部に設け
たマンホール等の開口部から長い管の先端に吹付
ノズルを設けたノズル体を炉内に差し込み、吹付
ノズルから耐火物を損耗箇所に吹付けて熱間補修
する方法が最近行なわれている。(Prior art) In a large industrial furnace such as the one mentioned above, if the refractories on the furnace wall are worn out, such as partially falling off, the furnace must be completely stopped and the temperature must drop before workers can enter the furnace. Repairing it requires a long waiting time for the temperature to drop, and requires a large amount of energy to raise the temperature after repair, which is extremely inefficient economically. Therefore, without lowering the temperature of the furnace, a nozzle body with a spray nozzle at the end of a long pipe is inserted into the furnace through an opening such as a manhole provided at the top of the side wall of the furnace, and the refractory is removed from the damaged area using the spray nozzle. Recently, a method of hot repair by spraying has been used.
ところがこの場合、ノズル体の長い管の一端を

体に座屈を生じ、その結果、炉壁の下方での補修
が極めて困難であつた。 However, in this case, if only one end of the long pipe of the nozzle body is supported by the manhole part, the nozzle body itself is long and may bend under its own weight, causing breakage of the nozzle body, or it may be difficult to stabilize the nozzle by facing the worn part. Since it is difficult to hold the nozzle body in place, the nozzle body is held by suspending it from a suitable position in the middle of the tube with a wire. However, since this wire is also pulled through near the upper end of the manhole, the angle between the nozzle body tube and the wire is small, and it is not very effective. In particular, the lower the area that requires repair is located in the furnace, the steeper the slope of the nozzle body becomes.
As a result, the angle between the nozzle body tube and the wire becomes smaller and smaller, and the effect of hanging with the wire disappears.At the same time, the nozzle body itself buckles due to the long nozzle body, and as a result, the furnace wall Repairs below were extremely difficult.
(考案の目的)
本考案は、上記従来例の欠点を解消するため

ノズル体の釣支装置を提供するものである。(Purpose of the invention) In order to eliminate the drawbacks of the above-mentioned conventional example, the present invention provides an arm protruding into the furnace at the upper edge of the manhole flange, and suspends the nozzle body with a wire from the tip of this arm. For hot spraying repair of industrial furnaces
The present invention provides a suspension device for a nozzle body.
本考案によれば、ノズル体の管とワイヤとがな
す角度が従来のものに比べて非常に大きくなり、
その結果、ノズル体の支持が安定するとともに、
炉壁の下方での補修も容易になるという効果を有
するものである。 According to the present invention, the angle formed between the tube of the nozzle body and the wire is much larger than that of conventional ones.
As a result, the nozzle body is supported stably, and
This has the effect of making repairs below the furnace wall easier.

FIG. 1 shows an embodiment of the present invention.
is an industrial furnace, and 2 is its inner wall, which is made of refractory material. 3 is a location where the fireproof wall is damaged and requires repair. 4
5 is a manhole provided in the upper part of the side wall of the furnace, and 5 is a nozzle body inserted into the furnace through the manhole 4, and a spray nozzle 6 is provided at the tip of a long pipe. At the time of repair, the refractory is transported through this together with compressed air and sprayed from the spray nozzle 6 for spraying work. 7
2 is a pulley holding jig according to the present invention, and as shown in FIG. The rear end of the arm is the upper edge of the manhole flange 4
It is pivoted to a. Reference numeral 10 denotes one or more wires (here, two wires) with one end fixed to an appropriate position of the tube of the nozzle body 5, and this wire 10 is attached to a pulley 8.
It extends to the operating part of the winch etc. 11 is a roller installed on the flange of the manhole.

作が困難になることは、(従来技術)の欄で述べ
た通りである。 Note that FIG. 1 also shows a conventional nozzle body support method for comparison, and the nozzle body 5'
It can be seen that the angle formed between the tube and the wire 10' supporting it is very small. At such a small angle, the effect of hanging with the wire becomes small, and at the same time, the nozzle body 5' itself buckles, making it difficult to spray effectively to the area to be repaired. As stated in the (Prior Art) section, the lower the spray nozzle portion of the nozzle body 5' is, the more difficult it becomes to operate.

ができる。 In contrast, in this embodiment, the nozzle body 5 is suspended from the tip of the arm 9 of the pulley holding jig 7 that has entered the furnace, so the angle between the tube of the nozzle body 5 and the wire 10 is different from that of the conventional one. becomes much larger compared to
Therefore, the balancing effect of the wire appears significantly, and the nozzle body 5 can be stably held. Then, while swinging the arm 9 of the pulley holding jig 7 horizontally to swing the spray nozzle 6 laterally, and moving the spray nozzle 6 upward or downward by adjusting the length of the wire 10 with a winch, Once the refractory is ejected, a trowel can be used to spray the required area of the area requiring repair.
