In the second state, a solid material extends across the intermediate door (95a) disposed between the two pockets (94), and the circumferential wall of the inner wall of the collecting chamber (12) is arranged with the buffer space (10) There is a fear of being caught between the intermediate doors 95a, but the outer surface 44 of the buffer space 40 is tapered to become closer to the opening surface 43 toward the rotational direction of the plurality of doors 95a. Having a curved surface, the space of the buffer space portion 40 becomes smaller as it goes in the rotational direction of the plurality of doors 95a, so that the opening area on the downstream end side of the buffer space portion 40 is smaller than the opening area on the upstream side. Since the pulling force is reduced and the pulling force on the downstream end side of the buffer space part 40 is weaker than the upstream side by the Pascal principle, it is seen in the rotational direction of the plurality of doors 95a among the two pockets 94 At this time, a portion of the elongated solid material located in the pocket 94 disposed on the downstream side moves through the buffer space portion 40 in the opposite direction of the rotational direction of the plurality of doors 95a to move the two pockets 94 ) In the direction of rotation of the plurality of doors (95a) flows into the pocket (94) disposed on the upstream side, an elongated solid material between the circumferential wall of the collecting chamber (12) and the door (95a) It is reliably prevented from being caught,

In addition, the solid material having a large weight or a large surface area is tapered toward the opening surface 43 in the form of an inclined wall with the downstream end of the outer surface 44 of the buffer space portion being prevented from flowing to the downstream end, and is stable. It is possible to transfer solids.

In addition, when one end of the suction pipe 81 is connected to flow to the downstream end side of the buffer space part 40, it is attached to the filter 21 of the second pocket 94 in which the filter cleaning mode is implemented. The buffer space part 40 and the collection space that flows with the first pocket 94 that implements the collection mode by transporting the solid material to the downstream end side of the buffer space part 40 via the suction pipe 81 While moving along the circumferential wall of the inner wall of the thread 12, the plurality of pockets 94 are partitioned and centrifugally moved from one door 95a, which is preceded in rotational motion, to a rotational motion. By being collected by the cyclone dust collecting principle at the bottom portion of the first pocket 94, the solids generated in the filter cleaning mode are not re-adhered to the filter 21 provided in the pocket 94 implementing the collecting mode. Thus, it is possible to prevent the suction power passing through the filter from dropping, so that the negative pressure is properly formed in the pocket 94 of the collecting mode, and thus the collecting efficiency can be stably maintained.

In addition, the collecting portion 10 of the embodiment is a plurality of doors (95a) is rotated between the opening surface 43 of the buffer space 40 and a plurality of pockets (94) of any one of the pocket 94 distribution As the area becomes larger and smaller, the solids flowing into the corresponding pocket 94 have a large centrifugal force in the early atmosphere and the late atmosphere where the distribution area becomes larger, thereby rotating along the inner wall of the corresponding pocket 94. In the middle and late periods of increasing and decreasing distribution area, and in the early and middle periods of getting smaller, the medium-sized solids flowing into the corresponding pocket 94 have a small centrifugal force to rotate along the inner wall of the corresponding pocket 94, Since it is introduced into the initial or late atmosphere, the medium-sized solid material rotates along the inner wall of the corresponding pocket 94 with a centrifugal force greater than the small centrifugal force, so that the cyclone-shaped chamber does not rotate without changing the inlet. The dust collection efficiency, that is, the collection efficiency can be increased more than the conventional cyclone.

In the description of the above embodiment, the driving source provided in the plurality of turning cyclone cleaners may also be replaced by a prime mover, in which case a blower, a solid material inlet, etc. may be driven to the prime mover by a power transmission means.

On the other hand, in the above embodiment, although the suction pipe 81 is described as being connected to flow through the buffer space portion 40, the present invention is not limited to this, and the suction pipe 81, like a venturi, is connected to the suction pipe 1 It can be connected right away.

And the rotational direction of the plurality of doors 95a of the collecting portion 10 of the above embodiments may be counterclockwise, as shown in FIGS. 3 and 4, but if it is clockwise, the pocket 94 ), since the pocket 94 rotates in an approaching direction to the airflow flowing in, the airflow velocity is greater than the airflow velocity during the counterclockwise rotation, thereby increasing the centrifugal force of the solids flowing into the airflow to increase the dust collection efficiency. It is preferable from the viewpoint that it can be made.
