That is, the suction nozzle (13) and the air blowing nozzle (15) are connected to the furnace cleaner (2). As the furnace cleaner (2) moves, the suction nozzle (13) and the air blowing nozzle (15) are automatically moved up and down and back and forth. By devising in this way, cleaning over the entire area around the riser base becomes possible.
[0020]
In more detail , the cleaner (1) for cleaning around the riser base of the present invention is configured as follows. That is, as shown in FIGS. 1 to 5 described later, a suction pipe (12) having a suction nozzle (13) on the free end side and a compressed air pipe (14) having an air blowing nozzle (15) on the free end side. And an interposition member (18) is provided.
[0021]

[0022]
Then, when the furnace cleaner (2) moves away from or approaches the riser (A) side, the suction nozzle (13) is moved by utilizing the vertical movement caused by the interposed member (18) along the guide (g). The suction pipe (12) provided and the compressed air pipe (14) provided with the air blowing nozzle (15) are automatically moved up and down.
[0023]
More specifically, the cleaner (1) for cleaning around the riser base of the present invention preferably has the following structure.
[0024]
That is, a suction member (13) provided on the free end side of the frame material (21) suspended from the cart (25) of the furnace cleaner (2) via the lever (11) serving as a link. A pipe (12) and a compressed air pipe (14) having an air blowing nozzle (15) on the free end side are installed. Of these, the suction pipe (12) is connected to the suction pipe (22) of the furnace cleaner (2).
[0025]
The frame material (21) and the suction pipe (22) are components of the furnace cleaner (2), but the suction pipe (12), the suction nozzle (13), the compressed air pipe (14), the air blowing nozzle (15) ) Is a member different from the suction branch pipes (23), (23) and the suction nozzles (24), (24) originally provided in the furnace cleaner (2).
[0026]
The suction nozzle (13) is connected to the suction pipe (22) of the furnace cleaner (2) through the suction pipe (12), but at the timing when the suction nozzle (24) of the furnace cleaner (2) does not operate. Since the suction nozzle (13) is operated, the suction capacity of the furnace cleaner (2) is not lowered, and suction by the suction nozzle (13) can be sufficiently performed. This timing state will be described with reference to FIGS. 7 to 8 which are a copy of FIG. 1. As shown in the piping system blacked out in FIG. 7, the suction nozzle (24) of the furnace cleaner (2) is operated to perform suction. When doing so, the suction nozzle (13) of the cleaning cleaner (1) around the riser pipe base is not operated, whereas the suction nozzle (2) of the furnace cleaner (2) is not as in the piping system shown in black in FIG. When the operation of 24) is stopped, the suction nozzle (13) of the cleaning cleaner (1) around the riser base is operated to perform suction.

[0028]
The suction nozzle (13) sucks and removes deposits around the base of the ascending pipe (A). However, since there are places around the base that cannot be removed by suction alone, the deposits accumulated in those places are blown out from the air blowing nozzle (15), and part of it is due to the suction nozzle (13). The rest is moved to the suctionable operating range, and the rest is moved to the suctionable range by the next suction nozzle (13) and the suctionable range by the suction nozzles (24), (24) of the furnace cleaner (2). The air blowing from the air blowing nozzle (15) through the compressed air piping (14) can use the exhaust gas from the suction blower of the furnace cleaner (2) without using a special device such as a compressor. This is advantageous.
[0029]
The suction nozzle (13) and the air blowing nozzle (15) are preferably replaceable. The angle of the air blowing nozzle (15) can be set as appropriate. The air blowing pressure can be adjusted arbitrarily, but in many cases a low pressure is sufficient, and dust or the like is not greatly scattered around. By adjusting the angle and discharge pressure of the air blowing nozzle (15), the deposit is moved to the operating range by the suction nozzle (13) and the suction nozzle (24) of the furnace cleaner (2).

[0032]
The interposed member (18) is, for example, a lever (18b) that rotates around a fulcrum (18a), and a rotating body (18c) provided on one end of the lever (18b) contacts the guide (g), The other end side may be connected to the lever (11) described above.
[0033]
The suction branch pipes (23) and (23) with the suction nozzles (24) and (24), which are originally provided on the furnace cleaner (2) side, operate using a conventional actuator.
[0034]
<Action>
By providing both the suction nozzle (13) and the air blowing nozzle (15) as described above, the deposit can be sucked and removed, and the deposit can be blown to a position where the suction can be removed. The entire area around the tube base can be cleaned.
[0035]
FIG. 4 shows an example of the shape of the air blowing nozzle (15) for the compressed air pipe (14). FIG. 5 is an explanatory view showing a cleaning state by the operation of the suction nozzle (13) and the air blowing nozzle (15). In FIG. 5, (a) shows the state of suction during forward movement, and the deposit in the central portion between the ascending pipes (A) is sucked and removed by the suction nozzle (13). At this time, the suction by the suction nozzle (24) of the furnace cleaner (2) is stopped. (B) shows a state of temporary stop at the forward end, and the deposits are moved by the blowing of compressed air mainly from the A nozzle of the air blowing nozzle (15). The deposit that has been blown and moved is sucked by the suction nozzle (13) next time. (C) shows the state when the vehicle is moving backward. The air cleaner nozzle (15) is mainly blown out of the compressed air from the nozzle B, and the residual cleaner on the furnace (2) between the rising pipes (A). Movement to the operating range is achieved. 5 (B) and (C), both the A nozzle and the B nozzle are operating. In (B), the deposition is mainly performed by the A nozzle, and in (C), the deposition is performed mainly by the B nozzle. Things will be moved.
[0036]
The suction nozzle (13) and the air blowing nozzle (15) are connected to the furnace cleaner (2), and as the furnace cleaner (2) moves, the suction nozzle (13) and the air blowing nozzle (15) When the vertical movement and vertical movement are made automatically, for example, when the guide (g) or lever (11) is used as described above, the furnace cleaner (2) moves away from the riser (A) side. Or, when approaching, the vertical movement of the interposed member (18) guided to the guide (g) is transmitted to the lever (11), and the suction pipe (12) provided with the suction nozzle (13) by the operation of the lever (11). ) And the pneumatic piping (14) provided with the air blowing nozzle (15) are automatically moved up and down.
[0037]
As a result, the suction nozzle (13) and the air blowing nozzle (15) automatically approach the furnace at the base of the riser (A) only when the furnace cleaner (2) approaches the riser (A) side. Thus, it is possible to reliably remove coal powder, surplus sealing material, dust and the like deposited around the base of the riser (A). Note that the timing and angle of suction-air blowing can be freely set.
The cleaner for cleaning around the riser pipe base portion of the present invention does not require a dedicated actuator.For example, using a fixed guide (g), the suction nozzle (13) incorporated in the furnace cleaner (2) and the air blowing Since the nozzle (15) is automatically raised and lowered, it is advantageous in terms of operation, equipment cost, energy, and maintenance, and an excellent cleaning effect is obtained regardless of the difficult to clean area around the riser base. Therefore, it is possible to solve the difficulty of cleaning around the riser base, which has been a concern in the past.
