  Hereinafter, an embodiment of a cartridge filter housing according to the present invention will be specifically described with reference to FIGS. In addition, in the following description, when showing the direction of up, down, left and right, it means up, down, left and right when viewed from the front of the figure.

  As shown in FIGS. 1 and 4, the cartridge filter housing 1 includes a cartridge filter housing body 10, and the cartridge filter housing body 10 includes an upper shell 11, a center shell 12, and a lower shell 13. It is configured.

  The upper shell 11 is formed in a cylindrical shape as shown in FIGS. 1, 3, and 4, and is eccentric from the central axis C, that is, as shown in FIGS. 1, 2, and 4. A fluid inlet nozzle 20 is provided at one end of the outer peripheral wall portion 11 a so as to penetrate into the upper shell 11. More specifically, the fluid inlet nozzle 20 has one end 20a projecting outward from the upper shell 11 and the other end 20b (see FIG. 4) facing the central axis C, It penetrates and is provided so that the part 11a and the inner peripheral wall part 11b may be followed. Thereby, when the fluid before filtration (the fluid to be filtered) flows from the fluid inlet nozzle 20 from the direction of the arrow P1 shown in FIGS. 1, 2, and 4, as shown in FIG. 4 (see also FIG. 2), Since the fluid to be filtered flows in along the inner peripheral wall portion 11b, a clockwise swirling flow is generated. Thereby, a better swirl flow is generated in the upper shell 11.

  On the other hand, as shown in FIGS. 1 and 3, the central shell 12 is formed in an inverted conical shape, and the upper opening edge portion 12 a and the bottom wall portion 11 c of the upper shell 11 are connected to each other. As a result, the central shell 12 and the upper shell 11 are integrally provided. At this time, as shown in FIGS. 1 and 4, a step portion 11 d is formed in the direction toward the central axis C on the upper opening edge portion 12 a of the central shell 12 and the bottom wall portion 11 c of the upper shell 11. Yes. Thus, by providing such a step portion 11d, the inner shell 12 (the inner diameter of the upper opening edge 12a) has a smaller diameter than the inner diameter of the upper shell 11. The swirling flow thus flowed into the central shell 12 having a smaller diameter results in a stronger swirling flow. Further, since the central shell 12 is formed so as to taper as it goes in the vertically downward direction, the rotation diameter of the swirling flow gradually decreases, and thus the strength of the swirling flow is maintained. This makes it possible to reduce the loss of swirling flow.

  On the other hand, as shown in FIGS. 1 and 5, the lower shell 13 is formed in a cylindrical shape, and its upper opening edge 13 a and the lower opening edge 12 b of the central shell 12 are connected. As a result, the lower shell 13 and the central shell 12 are integrally provided.

  Further, as shown in FIGS. 1, 3, and 5, a partition plate 21 made of a thick disc is provided near the center of the lower shell 13. Accordingly, the lower shell 13 is divided into a first lower shell 130 and a second lower shell 131. As shown in FIGS. 3 and 5, the first lower shell 130 is provided with a fluid drain nozzle 22 penetrating into the first lower shell 130 at one end of the outer peripheral wall portion 130 a. More specifically, as shown in FIG. 1, the fluid drain nozzle 22 is provided so as to protrude from the one end portion of the outer peripheral wall portion 130 a of the first lower shell 130 toward the outward direction from the central axis C. Thus, by providing the fluid drain nozzle 22 at such a position, the sludge (sludge) generated when the fluid to be filtered is filtered using the swirling flow generated in the clockwise direction can be removed from the fluid drain nozzle 22. Through the cartridge filter housing body 10 (in the direction of arrow P2 shown in FIGS. 1 and 5). Further, the fluid drain nozzle 22 is provided with a drain valve 22a (see FIGS. 1, 3 and 5). By opening the drain valve 22a, in the direction of the arrow P2 shown in FIGS. Sludge (sludge) can be discharged.

  On the other hand, as shown in FIG. 1, a cylindrical fluid outlet nozzle 23 projects from the bottom wall 131 a of the second lower shell 131 along the central axis C. From the fluid outlet nozzle 23, the filtered fluid (filtered fluid) is discharged in the direction of arrow P3 shown in FIGS.

  Thus, the cartridge filter 24 is erected along the central axis C as shown in FIG. 1 in the cartridge filter housing body 10 configured as described above. More specifically, as shown in FIG. 1, a pedestal 25 is erected along a central axis C in a hole 21 a penetrating the central portion of the partition plate 21, and the central axis C is formed above the pedestal 25. A center shaft 26 is erected along the cartridge shaft 24, and a cartridge filter 24 is erected so as to cover the center shaft 26. In order to fix the standing of the cartridge filter 24, a seal nut 27 is provided above the cartridge filter 24 and the center shaft 26. As a result, foreign matter of the fluid to be filtered that has flowed in from the fluid inlet nozzle 20 is captured by the cartridge filter 24, and the filtered fluid (filtered fluid) passes through the center shaft 26 and the pedestal 25 in the second lower shell 131. Will be flown into. Then, the filtered fluid that has flowed into the second lower shell 131 is discharged from the fluid outlet nozzle 23 in the direction of the arrow P3 shown in FIGS.

  On the other hand, the to-be-filtered fluid that has not passed through the cartridge filter 24, that is, that has not flowed into the center shaft 26 and the pedestal 25, is accumulated on the first lower shell 130 side as sludge. Then, the sludge (sludge) opens the drain valve 22a (see FIGS. 1, 3 and 5), and utilizes the swirl flow generated in the clockwise direction from the fluid drain nozzle 22 to FIG. , It is discharged in the direction of arrow P2 shown in FIG. Thereby, sludge (sludge) can be efficiently discharged outside.

  Incidentally, a lid 30 is provided on the upper part of the cartridge filter housing body 10 configured as described above, as shown in FIGS. As shown in FIGS. 1 and 3, the lid portion 30 includes a shell flange 300 and a cover flange 301. The shell flange 300 is formed in a donut-shaped thick plate, and the outer peripheral wall portion of the upper shell 11. It is fitted and attached to the upper part of 11a. The cover flange 301 is formed in a thick disk shape as shown in FIGS. 1 and 3, is placed on the shell flange 300, and is fixed by a plurality of bolts and nuts 302. Thereby, since the cover flange 301 is detachably provided on the shell flange 300, the cartridge filter 24 can be easily replaced. At this time, a pair of handle members 303 are integrally provided on the cover flange 301 in order to improve workability. The cover flange 301 is provided with a vent plug 304 on the central axis C as shown in FIG. Thereby, when the fluid to be filtered flows into the cartridge filter housing main body 10 from the fluid inlet nozzle 20, air can be extracted from the vent plug 304. As shown in FIG. 1, a gasket 305 is attached between the shell flange 300 and the cover flange 301 in order to ensure sealing performance.

  When using the cartridge filter housing 1 configured as described above, first, as shown in FIGS. 1, 2, and 4, the fluid to be filtered flows into the fluid inlet nozzle 20 from the direction of the arrow P1. . As a result, as shown in FIG. 4 (see also FIG. 2), since the fluid to be filtered flows in along the inner peripheral wall portion 11b, a clockwise swirling flow is generated, and in the upper shell 11, more A good swirl flow will be generated. As a result, foreign matter is not trapped and trapped in a part of the cartridge filter 24, and the foreign matter is trapped uniformly throughout the cartridge filter 24 as a whole.

  Next, as described above, the swirling flow generated in the upper shell 11 flows into the smaller-diameter central shell 12 and becomes a stronger swirling flow. As a result, the foreign matter is not concentrated and trapped in a part of the cartridge filter 24, and the foreign matter can be trapped uniformly throughout the cartridge filter 24. Further, since the central shell 12 is formed so as to taper as it goes in the vertically downward direction, the rotational diameter of the swirl flow gradually decreases, and thus the strength of the swirl flow is maintained. This makes it possible to reduce the loss of swirling flow. As a result, the foreign matter is not concentrated and trapped in a part of the cartridge filter 24, and the foreign matter can be trapped uniformly throughout the cartridge filter 24. Furthermore, foreign matters that adhere to the surface of the cartridge filter 24 and block the holes of the cartridge filter 24 can be washed away.

  Next, the filtered fluid, in which foreign matter is captured and filtered by the cartridge filter 24, flows into the second lower shell 131 through the center shaft 26 and the pedestal 25, and from the fluid outlet nozzle 23, the arrows shown in FIGS. It is discharged in the P3 direction.

  On the other hand, the fluid to be filtered that has not passed through the cartridge filter 24, that is, has not flowed into the center shaft 26 and the pedestal 25, is accumulated on the first lower shell 130 side as sludge (sludge) in the clockwise direction. Using the generated swirling flow, the fluid is discharged from the fluid drain nozzle 22 in the direction of the arrow P2 shown in FIGS.

  Thus, according to the present embodiment described above, the fluid to be filtered flows in along the inner peripheral wall portion 11b, so that a clockwise swirl flow is generated, and a better swirl in the cartridge filter housing body 10 is achieved. Since a flow is generated, foreign matter is not trapped and trapped in a part of the cartridge filter 24, and the foreign matter is trapped uniformly throughout the cartridge filter 24 as a whole.

  Therefore, according to the present embodiment, the service life of the cartridge filter can be extended and the number of replacements of the cartridge filter can be reduced, so that economic benefits can be improved and consideration for the environment is taken into consideration. be able to.

  The contents shown in the present embodiment are merely examples, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims.

  For example, in the present embodiment, an example in which the swirl flow is generated clockwise is shown, but it may be generated counterclockwise. In that case, the fluid inlet nozzle 20 may be provided at a position that is symmetrical with respect to the position illustrated in the present embodiment with respect to the central axis C (see FIG. 2). At that time, it is preferable that the fluid drain nozzle 22 is also provided at a position that is line-symmetric with respect to the position exemplified in the present embodiment with respect to the central axis C (see FIG. 1). This is because the sludge (sludge) generated when the fluid to be filtered is filtered using the swirl flow is discharged.

  Moreover, in this embodiment, although the example which fixes the shell flange 300 and the cover flange 301 with the volt | bolt and nut 302 was shown, you may fix not only that but a clamp band, a screw-in type, etc.
