Description

Loading and unloading filter container and filtering device using same

The present invention relates to a removable filter container and a filtering device using the same.

Conventionally, a filter device (not shown) having an inflow line that flows into a fluid to be filtered and an outflow line that discharges the fluid is detachably mounted between the inflow line side and the outflow line. A type of removable filter container 51. The detachable filter container 51 is made of resin. The detachable filter container 51 is shown in FIG. As shown in the figure, the detachable filter container 51 has an outer container 52 that is hollow inside, and a filter member 53 that is disposed in the hollow portion. Further, the first duct 54 and the second duct 55 are integrally formed in the outer container 52, and are fixed to the outer container 52. For example, a sealing member 54a and a sealing member 55a are attached to the outer circumferences of the first line 54 and the second line 55, respectively.

When the filter container 51 is attached to the filter device, for example, the first line 54 is fitted into the outflow line, and the second line 55 is inserted into the inflow line. Thereby, as shown by the arrow in FIG. 9, the fluid to be filtered which flows in from the inflow line passes through the second line 55 and passes through the inside of the outer container 2. The filter member 53 is discharged to the outside via the first line 54.

In the above-described filter device and filter container 51, since the first line 54 and the second line 55 are fixed to the outer container 52, the first line 54 is inserted into the outflow line, and the second line 55 is inserted. When embedded in the inflow line, the degree of freedom is small. In particular, since the outer container 52 is integrally formed of a resin, the relative position of the first line 54 to the second line 55 differs depending on the filter container 51 due to manufacturing tolerances, and it is difficult to communicate with the inflow line and The situation in which the outflow line is combined. In the above case, if it is hard to be bonded, the filter container, the sealing material of the joint portion, and the like are deformed, and the degree of sealing is lowered.

(First embodiment)

Hereinafter, a filter container 1 according to a first embodiment of the present invention will be described with reference to Fig. 1 . Figure 1 shows a filter container 1. Figure 2 shows the inside of section A-A of Figure 1. The filter container 1 of Fig. 1 includes an outer container 2, an inner container 3, and a filter member 4.

The outer container 2 is a container having a hollow portion inside, and can be formed, for example, of a resin. The outer container 2 is provided with a flow path hole 2a that communicates the inside of the outer container 2 with the outside. The flow path hole 2a functions as a flow path through which a fluid to be filtered flows. The outer container 2 has a wall surface that is formed to surround the flow path hole 2a and protrude from the outer surface of the outer container 2. Further, the outer container 2 is provided with a holding hole 2b. The holding hole 2b functions to hold the inner container 3 as will be described later. The outer container 2 can be configured, for example, by combining a lid portion 2c and a body portion 2d having an inner hollow and having an opening at one end. For example, the cover 2c must have at least a size that closes the opening of the main body portion 2d, and plugs the opening, and the portion protruding from the opening functions as a flange portion. The flow path hole 2a and the holding hole 2b are typically disposed on the cover 2c. The cover 2c and the body portion 2d are joined by, for example, welding.

The inner container 3 has a chamber housed in a hollow portion of the outer container 2. The inner container 3 has a flow path hole 3a that communicates the inside of the chamber of the inner container 3 with the outside. The flow path hole 3a functions as a flow path through which a fluid to be filtered flows. Here, the flow path hole 3a is formed It is the internal section of the second line 6 of the elongated pipe. The inner container 3 has a shape in which the second duct 6 protrudes from the chamber. The inner container 3 is such that a portion of the chamber is housed in the hollow portion of the outer container 2, and the second duct 6 is protruded from the holding hole 2b to the outside of the outer container 3. Then, the outer side surface of the wall surface 3b of the second duct 6 of the inner container 3 protruding outward from the holding hole 2b, and the inner side surface of the wall surface 2e surrounding the flow path hole 2a of the outer container 2, The division is formed as a first line 5. That is, for example, the first line 5 and the second line 6 are formed as a double line enclosing the second line 6 in the first line 5.

A mechanism for holding the inner container 3 by the outer container 2 will be described with reference to Figs. 3 and 4 . 3 and 4 are views as seen from the direction of arrow B of Fig. 1. The second conduit 6 is provided on the outer peripheral surface thereof with an ear piece 3c projecting from the outer peripheral surface thereof. As shown in Fig. 3, the holding hole 2b is provided with a cross section through which the second duct 6 can be inserted, and a portion having a slit through which the ear piece 3c can be inserted. At this time, the size of the holding hole 2b is slightly larger than that of the second line 6, and a gap is formed between the second line 6 and the holding hole 2b. In the state shown in Fig. 3, the tab 3c and the second conduit 6 pass the holding hole 2b from the inside of the outer container 2. After passing, the ears 3c are rotated 90 degrees along the axis extending by the second conduit 6. In this state, since there is no slit through which the tab 3c can pass, the tab 3c is caught by the cover 2c of the outer container, and the second conduit 6 cannot be pulled out. That is, the inner container 3 cannot be pulled away from the lid 2c and is held. In the inner container 3, the inner container 3 is kept in a state of being freely shaken by the gap between the outer peripheral surface of the second conduit 6 and the holding hole 2b. The flow path hole 2a and the holding hole 2b are representatively arranged In the cover 2c. As described above, the engagement by the welding of the lid 2c and the main body portion 2d is performed only after the second conduit is passed through the holding hole 2b of the lid 2c. Thereby, the inner container 3 is held in a state of being freely shaken in the outer container 2.

A filter member 4 is disposed inside the chamber of the inner container 3. The inside and the outside of the chamber penetrate from the position where the filter member 4 is disposed to the outside, and the fluid to be filtered passes through the flow passage hole 3a of the second conduit 6 to reach the filter member 4, and then flows out to the outside of the inner container 3, That is, the inside of the outer container 2. The fluid that has flowed out of the inside of the outer container 3 is discharged from the first line 5 through the flow path hole 2a. The fluid that should be filtered can also flow in reverse. Here, the filter member 4 is disposed inside the inner container 3, but may be disposed inside the outer container 2 without being disposed in the inner container 3. Any one of the outer container 2 and the inner container 3 may be held as long as it is disposed in a path through which the fluid to be filtered flows.

For example, the first line 5 is joined to an outflow line that flows out of the fluid to be filtered, and the second line 6 is joined to an inflow line that flows into the fluid to be filtered. However, it is also possible that the first line 5 is joined to the inflow line that flows into the fluid to be filtered, and the second line 6 is joined to the outflow line that flows out of the fluid to be filtered. That is, when the filter container 1 is attached to the filter device, either one of the first line 5 and the second line 6 is combined with the inflow line of the filter device, and the other is combined with the outflow line of the filter device. And a flow circuit is formed which has a fluid flowing from the inflow line through the filter member 4 to the outflow line. A sealing member 8 is disposed as shown in FIG. 2 at the joint portion with the inflow line. Figure 2 is connected to the inflow line on the outside of the second line 6. But it can also be joined on the inside of the second line 6. On the other hand, the first line 5 is engaged with an outflow line that flows out of the fluid to be filtered. A sealing member 7 is disposed as shown in Fig. 2 at the joint portion with the outflow pipe. 2 is joined to the inflow line outside the first line 5, but may be joined to the inflow line inside the first line 5. On the inner side of the first line 5, there are an inflow hole 2a and a holding hole 2b. The gap between the holding hole 2b and the second line 6 is not only isolated from the second line 6, but also functions as a flow path of the first line 5. Therefore, in the filtering device, the inflow line and the outflow line of the fluid to be filtered also make the second line 6 relative to the first line 5 when the first line 5 and the second line 6 are respectively joined. Since it is relatively free to sway, there is no problem of manufacturing error, and there is no problem due to individual differences in the size of the filter container 1, and it can be closely contacted. That is, in the first embodiment, the second conduit 6 is disposed inside the wall 2e forming the first conduit 5, and the flow passage hole 2a of the first conduit 5 is formed in the first conduit 2 The area between the inner side of the wall and the outer side of the wall 3b forming the second conduit 6. Then, the state of freely swaying means that the distance between the inner side of the wall 2e forming the first duct 5 and the outer side of the wall 3b forming the second duct 6 can be varied.

Hereinafter, a filter container 11 according to a second embodiment of the present invention will be described with reference to Figs. 5 and 6 . Figure 5 shows the filter container 11. Figure 6 shows the inside of section C-C of Figure 5. Hereinafter, differences from the first embodiment will be described, and the description of the same portions will be omitted.

In the first embodiment, the first duct 5 is disposed so as to surround the second duct 6, but the first duct may be independently disposed outside the second duct. That is, in the second embodiment, the first conduit 15 is disposed outside the second conduit 16. In this case, the inner container 13 is held freely in the outer container 12 in the same configuration as that of the first embodiment. Here, in the first embodiment, the gap between the holding hole 2b and the second conduit 6 is disposed inside the first conduit 5 and is disposed to be insulated from the second conduit 6. However, in the case of the second embodiment, the gap between the holding hole 12b and the second duct 16 is located outside the first duct 15, so it is necessary to restrict the flow of the fluid from the inside of the outer container 12. In the flow path hole 12a of the first line 15. To this end, a gasket 17 having a diameter of the first pipe 15 made of, for example, rubber or resin is prepared to close the gap between the holding hole 12b and the second pipe 16. The gasket 17 is attached to the lower side of the tab 13c so as to be pressed by the tab 13c. The sealing material 18 is disposed in the first conduit 15 and the second conduit 16 in the same manner as in the first embodiment. That is, in the second embodiment, the second conduit 16 is independently disposed outside the wall forming the first conduit 15. The flow path hole 12a of the first line 15 through which the fluid flows is formed inside the wall 12e forming the first line 15.

In the second embodiment, it is necessary to seal the gap between the holding hole 12b and the second pipe 16 by the gasket 17, but when the first pipe 15 and the second pipe 16 are joined, The second conduit 16 is also relatively free to sway relative to the first conduit 15, so that there is no manufacturing error, and there is no individual difference in the size of the filter container 1. The problems caused by the difference can be closely connected. In the second embodiment, the free sway means that the distance between the wall surface on the outer side of the first duct 5 and the wall surface on the outer side of the second duct 6 can be varied.

Hereinafter, a filter container 21 according to a third embodiment of the present invention will be described with reference to Figs. 7 and 8 . Figure 7 shows the filter container 21. Fig. 8 shows the inside of the section D-D of Fig. 7. Hereinafter, differences from the first embodiment will be described, and the description of the same portions will be omitted.

In the first embodiment, the flow path holes 2a are disposed in the outer container 2. However, it can also be placed in the inner container. In other words, in the third embodiment, the outer container 22 does not have the cover member, and the tab 23c largely protrudes from the wall surface 23b of the second duct 6 of the inner container 23, and functions as a cover member. On the inner side of the outer container, a claw for holding the tab 23c is disposed, which holds the tab 23c to plug the opening of the outer container 22. The tabs 23c are not completely fixed but are kept free to sway. The inner container 23 is provided with a flow path hole 23f in the ear piece 23 in addition to the flow path hole 23a of the second line 26. The flow path hole 23f has the same function as the flow path hole 2a of the outer container 2 of the first embodiment. Even in this embodiment, the flow path 23d is located at the inner side of the first line 25, so that the gap between the ear piece 23c and the outer container 22 forms a part of the cross-sectional area of the flow path of the first line 25. Therefore, as far as the effect is concerned, it has the same form as the first form.
