Further, as shown in FIG. 3, the granular material removing device 6 is a power transmission mechanism (for example, a motor pulley or a belt or chain 13 hung on a sprocket 12 by a motor pulley or a pulley or a sprocket of a shaft 7 of the granular material removing device 6. 14), and is driven to rotate by a driving device.
[0010]
Two V belts 15 are attached to the inner surfaces of the front and rear end portions of the endless filter medium 5 , respectively. The V belt 15 is fitted into a groove 16 for the V belt formed on the outer periphery of the end portion of each roll, and is endless. The sealant 17 is slidably fitted into the groove 18 for the V belt of the sealant 17 facing the inner surfaces of the front and rear end portions of the filter medium 5 , and the sealant 17 is made of a material having a low friction coefficient and is fixed to the inner surface of the casing. It is attached to the plate 19.
[0011]
Thus, the outer sides of the front and rear end portions of the endless filter medium 5 are pushed by the tension roller 20 so that the V-belt 15 can slide into the V-belt groove 18 of the sealing material 17 in a dense manner, or the V-belt groove 18. The tension roller support 21 is attached to the inside of the casing so as to have a labyrinth seal function with a slight gap from the inside. The tension roller 20 is applied with a pressing force to the endless filter medium 5 by an appropriate spring mechanism, and there are various pressing force applying mechanisms, and the description thereof will be omitted.
[0012]
The end of each roll 4 is slidably fitted in the block recess 23 of the sealing block 22, and this sealing block is attached to the support plate 19 for the sealing material 17. Recess 23 of the block of the sealing block 22 surrounds the end of the roll while leaving a portion of the roll 4 is in contact with the endless filter medium (with an arc angle of the roll 90 degrees), in contact with the endless filter medium 5 of the sealing block 22 A V-belt groove 24 into which the V-belt 15 is fitted is formed on the surface.
[0013]

Central portion of the air units A from the central passage 27 in the air from the housing inlet 26 is in this embodiment enters through an endless filter medium 5 of the surface facing the units in A, the next step from the air outlet 3 Part, for example, the wind tunnel 29 of the snow test apparatus using artificial snow is exhausted.
[0014]
Air left and right sides from the housing inlet 26 enters between the side plates and the respective units of the unit receiving housing 25 by lateral passage 28, from the air outlet 3 have in each unit through the outer surface of the endless filtering medium 5 It is exhausted. Thus, each unit A, A collects the granular material by the endless filter medium 5 , and the collected granular material is separated from each endless filter medium 5 by the granular material removing device 6 and collected. In addition, the air blower is provided in the suitable place of the wind tunnel, for example, and the circulating air by the air blower in a wind tunnel passes a unit.
[0015]
[Action / Effect]
The air to be treated that flows into the casing 1 from the air inlet 2 passes through the endless filter medium 5 , but the particulate matter in the air to be treated is collected by the endless filter medium 5 when passing through the filter medium, and the treated air from which the particulate matter has been removed. Is exhausted from the air outlet 3. Thus particulate matter collected on the endless filtering medium 5 is recovered is is disengaged from the endless filtering medium 5 by the removal device 6 of the granular material.
[0016]
Therefore, unlike conventional cyclone recovery devices, it is not necessary to install a tall cyclone generator tower, which saves installation space and reduces manufacturing costs. It is not necessary to generate a large air flow, and the pressure loss of the air blow is small, so that the running cost can be reduced.
[0017]
