  Next, the operation of the first embodiment will be described. When recovering the cellulose fiber heat insulating material in the outer wall according to the first embodiment, for example, as shown in FIG. 1, first, the bucket support portion 2 is moved by the caster 2 a, and the bucket 1 is moved above the outer wall. Oppose to any part. At this time, the bucket 1 can be easily stopped at an arbitrary height position by the balancer 5. At this time, as shown in FIG. 1 and the like, it is preferable that a hose for transferring the cellulose fiber heat insulating material 10 to the cyclone portion 12 is connected to the bucket 1 in advance.

  Thereafter, the wallpaper, the plasterboard 8 and the lining sheet of the outer wall portion are peeled off to expose the cellulose fiber heat insulating material 10 therein, and the exposed cellulose fiber heat insulating material 10 is placed in the bucket 1 (manually or manually). Move and house (by mechanical device). Thereafter, the bucket 1 is moved to the other part of the outer wall (for example, by operating the balancer 5 and lowering the bucket 1 by a predetermined distance and then stopping), the same operation is performed. It repeats until the cellulose fiber heat insulating material 10 is almost filled in the bucket 1. Specifically, when the temporary collection operation to the bucket 1 at the height position as shown in FIG. 1 is completed, the bucket 1 is lowered downward by a predetermined distance from the position, and the same operation is performed at the height position. Repeat until the height of bucket 1 is at the bottom of the wall. Then, the same operation is repeated after moving in the horizontal direction of FIG.

  In the first embodiment, as a general rule, the cellulose fiber heat insulating material 10 in the wall body is moved to the bucket 1 and temporarily collected using the bucket 1, but in particular the corner of the wall body, etc. For the cellulose fiber heat insulating material 10 in the narrow part of the wall, temporarily remove the hose 3 from the bucket 1, insert the tip of the hose 3 directly into the narrow part of the wall, The cellulose fiber heat insulating material 10 may be sucked into the hose 3 (and further transferred to the cyclone unit 12).

  When the cellulose fiber heat insulating material 10 is almost filled in the bucket 1, the power of the cyclone device is turned on to operate the blower 20. Then, the cellulose fiber heat insulating material 10 is transferred from the bucket 1 through the hose into the cyclone unit 12 of the cyclone device (recovery capacity is 200 kg / h) by the suction force (air flow action) of the blower 20. ). The cellulose fiber heat insulating material 10 and the air flow transferred into the cyclone portion 12 rotate at a high speed in the cylindrical cyclone portion 12. In the process, the cellulose fiber heat insulating material 10 and the air flow are Are separated. The cellulose fiber heat insulating material 10 moves downward and falls into the storage container (see reference numeral 22 in FIG. 6). On the other hand, the air flow moves upward, moves in the hose 16, is cleaned by the filter parts 17 and 18, and is then discharged from the exhaust port 19 into the atmosphere.

  As described above, in the first embodiment, the bucket support portion 2 moves the bucket 1 in the vertical direction while facing the inner side of an arbitrary portion of the outer wall of the building at an appropriate height position. Keep it stationary. Then, in that state (further removing the wallpaper and the lining sheet to expose the cellulose fiber heat insulating material 10 to the inside of the room), the cellulose fiber heat insulating material 10 in the outer wall is moved and accommodated in the bucket 1. Thereafter, the air blowing section is turned on, and the cellulose fiber heat insulating material 10 moved and accommodated in the bucket 1 is moved to the cyclone section 12 through the hose (transfer pipe) 3 together with the air flow. In the cyclone part 12, the cellulose fiber heat insulating material and the air flow which have moved through the hose (transfer pipe) 3 are separated from each other by a rotational force, and the cellulose fiber heat insulating material 10 is moved downward and the air flow is Move upward. Further, the cellulose fiber heat insulating material 10 from the cyclone portion 12 is collected in a lower collection container 22. The air flow from the cyclone unit 12 is filtered and cleaned by the filter units 17 and 18 and then released from the exhaust port 19 into the atmosphere. Moreover, in the present Example 1, since the said bucket support part 2 is provided with the balancer (a weight is included), it becomes possible to make it easy to make the said bucket rest still now in arbitrary height positions. Furthermore, in this Example 1, since the said cellulose fiber heat insulating material 10 is comprised by the dry wood fiber which does not contain an adhesive agent as mentioned above, the said cellulose fiber heat insulating material 10 is used for another building. Even when reused, the quality will not deteriorate. Moreover, in this Example 1, the utility required for collection | recovery of the cellulose fiber heat insulating material 10 is only electric power required for operation | movement of a collection | recovery apparatus, and other utilities (for example, industrial water, compressed air, other cooling) -A device such as heat insulation and drying is not necessary, but this point is also a merit of the first embodiment.

Various modifications and changes are possible.

  For example, in the first embodiment, as described above, when the cellulose fiber heat insulating material 10 in the wall body is temporarily recovered, the bucket 1 is used, but only a narrow portion such as a corner of the wall body. Only for the cellulose fiber heat insulating material 10 located in the wall, the tip of the hose 3 removed from the bucket 1 is directly inserted into the narrow portion of the wall body so as to suck the cellulose fiber heat insulating material 10. However, the present invention is not limited to this. In the present invention, for example (without using the bucket 1), the tip of the hose 3 is directly inserted into each part in the wall (in this case, for supporting the height position of the hose 3, etc.) A known support portion is also provided), so that the cellulose fiber heat insulating material 10 of each portion is sucked and transferred to the cyclone portion, and the bucket 1 is used for all the cellulose fiber heat insulating materials 10 in the wall. The hose 3 may be used for suction / recovery.

  Moreover, in the said Example 1, "the cellulose fiber heat insulating material which consists of the dry wood fiber which does not contain an adhesive agent" with which the said wall body was filled (the cellulose fiber heat insulating material which this inventor is using at the time of construction) ) Using the bucket 1, the hose 3, the blower 20, and the cyclone unit 12, etc., but in the present invention, not the present inventor but other companies use cellulose used for construction. Of course, it can also be used to recover fiber insulation (cellulose fiber insulation consisting of wet wood fibers with adhesive).

  Further, in the present invention, “the transfer pipe support portion for supporting the transfer pipe (hose) so that the other end is inserted into an arbitrary portion inside the wall” is, for example, the bucket support of the first embodiment. It is possible to use the portion 2 by opening an opening in the bucket support portion 2 and inserting a transfer pipe (hose) therein.
