  At this time, the space 11 in the casing (filter body) 10 is made up of the inner drainage space 11a, the purified water space 11c, and the outer drainage space 11b by the small-diameter separator 51 and the large-diameter separator 52 in order from the radial center to the outside. Divided into three spaces. The inner drain discharge port 42a, the purified water discharge port 42c, and the outer drain discharge port 42b communicate with the inner drain space 11a, the purified water space 11c, and the outer drain space 11b, respectively.

  Here, in the present embodiment, a centrifugal force generating means for generating a centrifugal force in water (fluid) flowing into the casing (filter body) 10 is provided.

  Specifically, a wall surface flow along the inner surface of the side wall portion 32 of the reduced diameter cylindrical member 30 is obtained by flowing water from an inlet 32a extending in a tangential direction of the reduced diameter cylindrical member 30 provided in a substantially cylindrical shape. It is trying to generate. In this way, water is swirled by generating a wall surface flow in the water flowing in from the inflow port 32a, and the water is swirled so that centrifugal force is applied to the water (fluid) flowing into the casing (filter body) 10. Is generated.

  At this time, as shown in FIG. 2, the water that has flowed into the casing (filter body) 10 rises inside the casing (filter body) 10 while spirally swirling by the wall surface flow, and the inner drain discharge port 42 a, purified water It is discharged out of the casing (filter body) 10 from the discharge port 42c and the outer drain discharge port 42b.

  Thus, in this embodiment, since the water is swirled spirally, the direction of action of the centrifugal force generated in the water is substantially the radial direction.

  That is, the space 11 in the casing (filter body) 10 according to the present embodiment is formed by a small-diameter separator 51 and a large-diameter separator 52 (a plurality of porous separators) arranged substantially in parallel in the radial direction (direction of centrifugal force action). The inner drainage space 11a, the purified water space 11c, and the outer drainage space 11b (a plurality of spaces) are partitioned. A plurality of discharge ports (inner drain discharge port 42a, purified water discharge port 42c, outer drain discharge port 42b) are provided so as to communicate with the inner drain space 11a, the purified water space 11c, and the outer drain space 11b (respective spaces). It has been.

  Next, the operation of the centrifugal filter 1 according to this embodiment will be described.

  First, the water that flows in from the inflow port 32a extending in the tangential direction of the reduced diameter cylindrical member 30 provided in a substantially cylindrical shape swirls spirally by the wall surface flow.

  At this time, foreign matter having a large particle size and a relatively small specific gravity, such as dust floating in water, moves inward (center side of the swirl flow) by centrifugal force generated in water (fluid). Then, it passes through the through-hole 31b, moves into the inner drainage space 11a, passes through the inner drainage space 11a, and is discharged from the inner drainage discharge port 42a to the outside of the casing (filter body) 10. In addition, foreign matter having a relatively large specific gravity, such as gravel with a large particle size, passes through the through-hole 33c and moves into the outer drainage space 11b, passes through the outer drainage space 11b, and passes through the casing (filter body) from the outer drainage discharge port 42b. ) 10 discharged outside.

  Thus, the water from which the foreign matter having a large particle size and a relatively large specific gravity and the foreign material having a large particle size and a relatively small specific gravity are removed rises in the purified water space 11c while turning. At this time, a centrifugal force acts on the water by the swirling flow, and accordingly, a foreign substance having a large specific gravity that cannot be removed by the through-hole 33cb passes through the large-diameter separator 52 together with the water and moves into the outer drainage space 11b. To do. And the foreign material with small specific gravity passes the small diameter separator 51 with water, and moves in the inner side drainage space 11a. And the foreign material which moved to the outer side waste_water | drain space 11b is discharged | emitted from the outer side waste_water | drain discharge port 42b to the casing (filter main body) 10 exterior. Further, the foreign matter that has moved to the inner drainage space 11a passes through the inner drainage discharge port 42a, joins the outer drainage discharge port 42b, and is discharged from the outer drainage discharge port 42b to the outside of the casing (filter body) 10.

  Thus, the purified water from which the foreign matter having a large specific gravity and the foreign matter having a low specific gravity are removed flows from the purified water space 11c to the purified water discharge port 42c.

  As described above, in the present embodiment, the space 11 in the casing (filter body) 10 has a small diameter separator 51 and a large diameter separator 52 (a plurality of porous holes) arranged substantially in parallel in the radial direction (direction of centrifugal force action). Partition) into an inner drainage space 11a, a purified water space 11c, and an outer drainage space 11b (a plurality of spaces). A plurality of discharge ports (inner drain discharge port 42a, purified water discharge port 42c, outer drain discharge port 42b) are provided so as to communicate with the inner drainage space 11a, the purified water space 11c, and the outer drainage space 11b (respective spaces). ing.

  Further, in the present embodiment, a centrifugal force generating means for generating a centrifugal force in water (fluid) flowing into the casing (filter body) 10 is provided.

  In this way, by providing the centrifugal force generating means, the foreign matter having a large specific gravity can be moved to the outer peripheral side and the foreign matter having a small specific gravity can be moved to the inner peripheral side by the centrifugal force generated in the water (fluid). And since the purified water space 11c is provided in the substantially middle part of radial direction, and the purified water discharge port 42c is connected to the said purified water space 11c, the water from which the foreign material with large specific gravity and the foreign material with small specific gravity were removed is the purified water discharge port 42c. It can be discharged from.

  That is, according to the present embodiment, it is possible to obtain the centrifugal filter 1 that can separate not only foreign matter having a high specific gravity but also foreign matter having a low specific gravity.

  Moreover, according to this embodiment, the structure of the casing (filter main body) 10 can be simplified, and the centrifugal filter 1 can be reduced in size.

  Moreover, according to this embodiment, since the small diameter separator 51 and the large diameter separator 52 are provided, it is possible to suppress the foreign matter removed by the swirling flow from flowing backward and mixing into the purified water. The separation efficiency can be further increased. Furthermore, the centrifugal filter 1 according to the present embodiment does not require replacement and is economical.

  Moreover, according to this embodiment, water flows in from the inflow port 32a extended in the tangential direction of the reduced diameter cylindrical member 30 provided in the substantially cylindrical shape, and is along the inner surface of the side wall part 32 of the reduced diameter cylindrical member 30. Generated wall flow. Then, the centrifugal force is generated in the water (fluid) flowing into the filter body by turning the water by the wall surface flow. Therefore, since it is not necessary to provide the driving means in the centrifugal filter 1, the centrifugal filter 1 can have a simpler configuration and can be downsized.

  Thus, the centrifugal filter 1A according to the present embodiment is formed.

  At this time, the space 11 in the casing (filter body) 10 is made up of the inner drainage space 11a, the purified water space 11c, and the outer drainage space 11b by the small-diameter separator 51 and the large-diameter separator 52 in order from the radial center to the outside.

  Next, the operation of the centrifugal filter 1A according to this embodiment will be described.

  First, the motor 70 is driven to rotate the rotating body 80. Then, when water is introduced from the inflow port 32a into the water passage 82d with the rotating body 80 rotated, the water introduced into the water passage 82d is introduced into the purified water space 11c through the through-hole 82g. .

  At this time, due to the rotation of the rotating body 80, centrifugal force acting in the radial direction is generated on the water introduced into the purified water space 11c.

  Due to the centrifugal force, foreign matter having a relatively large specific gravity, such as gravel with a large particle size, passes through the through-hole 82j and moves into the outer drainage space 11b and passes through the outer drainage space 11b to the outer drainage discharge port 42b. From the casing (filter body) 10 to the outside. Further, foreign matters having a relatively small specific gravity, such as dust floating in water, move inward (center side of the swirl flow) by centrifugal force generated in water (fluid). Then, it passes through the through-hole 82i, moves into the inner drainage space 11a, passes through the inner drainage space 11a, and is discharged from the inner drainage discharge port 42a to the outside of the casing (filter body) 10.

  Thus, the water from which the foreign matter having a relatively high specific gravity and the foreign matter having a relatively low specific gravity are removed rises in the purified water space 11 c while turning by the rotation of the rotating body 80. Then, due to the centrifugal force generated in the water, a foreign substance having a large specific gravity that cannot be removed by the through-hole 82j passes through the large-diameter separator 52 together with the water and moves into the outer drainage space 11b. And the foreign material with small specific gravity passes the small diameter separator 51 with water, and moves in the inner side drain space 11a. The foreign matter thus moved to the outer drainage space 11b is discharged out of the casing (filter body) 10 from the outer drainage discharge port 42b. In addition, the foreign matter that has moved to the inner drainage space 11a is discharged out of the casing (filter body) 10 from the inner drainage discharge port 42a.

  Thus, the purified water from which the foreign matter having a large specific gravity and the foreign matter having a low specific gravity are removed flows from the purified water space 11c to the purified water discharge port 42c.

  Also according to the present embodiment described above, substantially the same effect as in the first embodiment can be obtained.

  In the present embodiment, the rotating body 80 including the small diameter separator 51 and the large diameter separator 52 and the motor 70 connected to the rotating body 80 constitute centrifugal force generating means.

  Thus, by generating centrifugal force in water using the motor 70, strong centrifugal force can be applied and the separation efficiency of foreign matters can be further enhanced.

(Third embodiment)
A centrifugal filter 1B according to this embodiment is obtained by connecting the centrifugal filter 1 and the centrifugal filter 1A exemplified in the first and second embodiments in series.

  As shown in FIG. 4, the centrifugal filter 1B has the centrifugal filter 1 disposed on the upstream side of the centrifugal filter 1A.

  That is, the centrifugal filter 1A having a large centrifugal force generated in water (fluid) is arranged downstream of the centrifugal filter 1 having a small centrifugal force generated in water (fluid) than the centrifugal filter 1A.

  As described above, in the centrifugal filter 1B according to the present embodiment, coarse dust removal is performed by the centrifugal filter 1 disposed on the upstream side, and finer dust removal is performed by the centrifugal filter 1A disposed on the downstream side. I have to.

  In addition, it is preferable to select a separator having a smaller separation diameter.

  In the present embodiment, the upstream centrifugal filter 1 uses a separation membrane of about 10 μm as a separator, and the downstream centrifugal filter 1A uses a separation membrane of about 1 μm as a separator.

  According to the above-described embodiment, the separation efficiency of impurities can be further increased by providing a motor to increase the rotational speed and apply a strong centrifugal force.

  Next, a modification of the centrifugal filter according to this embodiment will be described.
