Abstract

A filter container is provided with: an outer container in communication with a first duct; an inner container in communication with a second duct and held so that at least a portion of the inner container is located within the outer container; and a filter member held by the outer container and/or the inner container. When the filter container is mounted to a filtration device, the first duct and/or the second duct is joined to the inflow duct of the filtration device while the other is joined to the outflow duct of the filtration device, thereby enabling the formation of a flow circuit through which fluid flows from the inflow duct through the filter member to the outflow duct, and the second duct is held so that the second duct freely rocks relative to the outer container.

Description

Detachable filter container and filtration device using the same

The present invention relates to a detachable filter container and a filtration device using the same.

2. Description of the Related Art Conventionally, in a filtering device (not shown) including an inflow conduit into which a fluid to be filtered flows in and an outflow conduit from which the fluid is discharged, the detachable attachment is provided between the inflow conduit side and the outflow conduit. A removable filter container 51 of the type that can be used is used. The removable filter container 51 is made of resin. FIG. 9 shows a detachable filter container 51. As shown here, the detachable filter container 51 has an outer container 52 having a hollow inside and a filter member 53 disposed in the hollow part. In addition, a first conduit 54 and a second conduit 55 are integrally formed in the outer container 52 and fixed to the outer container 52. For example, a seal member 54a and a seal member 55a are attached to the outer circumferences of the first pipeline 54 and the second pipeline 55, respectively.

When the filter container 51 is attached to the filtration device, for example, the first pipeline 54 is fitted into the outflow pipeline and the second pipeline 55 is fitted into the inflow pipeline. As a result, as shown by the arrow in FIG. 9, the fluid to be filtered flowing from the inflow pipe passes through the filter member 53 in the outer container 2 via the second pipe 55 and passes through the first pipe. It is discharged outside via 54.

In such a filtering device and the filter container 51, the first conduit 54 and the second conduit 55 are fixed to the outer container 52. Therefore, the first conduit 54 is connected to the outflow conduit, and the first conduit 54 is connected to the inflow conduit. When fitting the two pipe lines 55, the degree of freedom is small. In particular, since the outer container 52 is integrally formed of resin, the relative position of the first conduit 54 with respect to the second conduit 55 differs for each filter container 51 due to manufacturing tolerances, and is combined with the inflow conduit and the outflow conduit. It may be difficult. In such a case, if the coupling is forcibly performed, the filter container, the sealing material in the coupling portion, and the like are deformed, and the sealing degree is lowered.

A filter container detachably attachable to a filtration apparatus comprising an inflow conduit through which a fluid before filtration flows and an outflow conduit through which the fluid after filtration flows, wherein the filter container communicates with a first conduit An outer container, an inner container that is held so that at least a portion thereof is located inside the outer container, and communicates with a second pipe line; and a filter member that is held by at least one of the outer container and the inner container; And when the filter container is attached to the filtration device, one of the first conduit and the second conduit is coupled to the inflow conduit and the other is coupled to the outflow conduit. The fluid flow circuit that flows from the inflow conduit through the filter to the outflow conduit can be formed, and the second conduit is free to swing with respect to the outer container. Retained Solved by the filter container.

∙ It is possible to provide a filter that can be easily combined with an inflow pipe and an outflow pipe even when taking into account dimensional tolerances in manufacturing the filter container.

The filter container in 1st embodiment of this invention is shown. It is sectional drawing which showed the cross section of the filter container in 1st embodiment of this invention. In the first embodiment of the present invention, the state before holding the mechanism for holding the inner container in the outer container is shown. In the first embodiment of the present invention, the holding state of the mechanism for holding the inner container in the outer container is shown. The filter container in 2nd embodiment of this invention is shown. It is sectional drawing which showed the cross section of the filter container in 2nd embodiment of this invention. The filter container in 3rd embodiment of this invention is shown. It is sectional drawing which showed the cross section of the filter container in 3rd embodiment of this invention. 1 shows a conventional filter container.

(First embodiment)
Hereinafter, with reference to FIG. 1, the filter container 1 in 1st embodiment of this invention is demonstrated. FIG. 1 shows a filter container 1. FIG. 2 shows the inside of section AA of FIG. The filter container 1 in 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 part inside, and is made of, for example, resin. The outer container 2 includes a flow path hole 2 a that communicates the inside and the outside of the outer container 2. The channel hole 2a functions as a channel for flowing a fluid to be filtered. The outer container 2 has a wall surface formed so as to protrude from the outer surface of the outer container 2 so as to surround the flow path hole 2a. The outer container 2 has 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 by combining, for example, a lid 2c and a main body 2d that is hollow inside and has an opening at one end. For example, the lid 2c has at least a size for closing the opening of the main body portion 2d, and closes the opening, and a portion protruding from the opening functions as a flange. The channel hole 2a and the holding hole 2b are typically arranged in the lid 2c. The lid 2c and the main body 2d are joined by welding, for example.

The inner container 3 has a number of chambers stored in the hollow part of the outer container 2. The inner container 3 has a flow path hole 3 a that communicates the inside and the outside of the chamber of the inner container 3. The channel hole 3a functions as a channel for flowing a fluid to be filtered. Here, the flow path hole 3a is formed as an internal cross section of the second pipe line 6 which is an elongated pipe line. The inner container 3 has a shape that extends so that the second pipeline 6 protrudes from the chamber. The inner container 3 is configured such that the chamber portion is accommodated in the hollow portion of the outer container 2, and the second duct 6 protrudes outside the outer container 3 from the holding hole 2 b. In the region between the outer surface of the wall surface 3b of the second conduit 6 of the inner container 3 protruding outward from the holding hole 2b and the inner surface of the wall surface 2e surrounding the flow path hole 2a of the outer container 2, It forms so that the pipe line 5 may be defined. That is, for example, the first pipeline 5 and the second pipeline 6 are formed as a double pipeline in which the second pipeline 6 is enclosed in the first pipeline 5.

Referring to FIG. 3 and FIG. 4, the mechanism in which the outer container 2 holds the inner container 3 will be described. 3 and 4 are views seen from the direction of arrow B in FIG. The 2nd pipe line 6 equips the outer peripheral surface with the tab 3c which protrudes from the outer peripheral surface. As shown in FIG. 3, the holding hole 2 b has a cross section through which the second pipe 6 can be inserted, and a part of a notch through which the tab 3 c can be inserted. At this time, the size of the holding hole 2b is slightly larger than that of the second pipe 6 so that a gap is formed between the second pipe 6 and the holding hole 2b. In the state shown in FIG. 3, the tab 3 c and the second pipeline 6 pass through the holding hole 2 b from the inside of the outer container 2. After passing, the tab 3c is rotated 90 degrees along the axis along which the second pipe line 6 extends. In this state, since there is no cutout through which the tab 3c can pass, the tab 3c is caught by the lid 2c of the outer container, and the second conduit 6 cannot be pulled out. That is, the inner container 3 is held without being pulled out from the lid 2c. The inner container 3 is held in a freely swingable state with respect to the lid 2c by the gap between the outer peripheral surface of the second pipeline 6 and the holding hole 2b. The channel hole 2a and the holding hole 2b are typically arranged in the lid 2c. As described above, the joining of the lid 2c and the main body portion 2d is performed after the second pipe line is passed through the holding hole 2b of the lid 2c and held. Thereby, the inner container 3 is held in the outer container 2 in a freely swingable state.

A filter member 4 is arranged inside the chamber of the inner container 3. The inside and outside of the chamber penetrates to the outside from the place where the filter member 4 is arranged, and the fluid to be filtered reaches the filter member 4 through the flow path hole 3a of the second pipe 6 and from there to the inner container 3 flows out to the outside of 3, that is, inside the outer container 2. The fluid that has flowed into the outer container 3 is discharged from the first pipe line 5 through the flow path hole 2a. The fluid to be filtered may flow in reverse. Here, the filter member 4 is disposed inside the inner container 3, but may be disposed not inside the inner container 3 but inside the outer container 2. As long as the fluid to be filtered is arranged in the path through which it flows, it may be held in at least one of the outer container 2 and the inner container 3.

For example, the first pipeline 5 is joined to an outflow pipeline through which the fluid to be filtered flows out, and the second pipeline 6 is joined to an inflow pipeline through which the fluid to be filtered flows. However, the first pipe line 5 may be joined to the inflow pipe line into which the fluid to be filtered flows, and the second pipe line 6 may be joined to the outflow pipe from which the fluid to be filtered flows out. That is, when the filter container 1 is attached to the filtration device, one of the first pipeline 5 and the second pipeline 6 is connected to the inflow pipeline of the filtration device, and the other is the outflow pipeline of the filtration device. And a fluid flow circuit is formed which flows from the inflow line through the filter member 4 to the outflow line. As shown in FIG. 2, a sealing material 8 is disposed at the junction with the inflow conduit. In FIG. 2, the inflow conduit is joined outside the second conduit 6, but may be joined inside the second conduit 6. On the other hand, the first pipe line 5 is joined to the outflow pipe from which the fluid to be filtered flows out. As shown in FIG. 2, a seal material 7 is disposed at the junction with the outflow pipe. In FIG. 2, the inflow conduit is joined to the outside of the first conduit 5, but the inflow conduit may be joined to the inside of the first conduit 5. An inflow hole 2 a and a holding hole 2 b are located inside the first pipeline 5. The gap between the holding hole 2 b and the second pipeline 6 is also isolated from the second pipeline 6 and can function as a flow path of the first pipeline 5. Therefore, in the filtering device, the second pipe 6 is also connected to the first pipe when the first pipe 5 and the second pipe 6 are joined to the inflow pipe and the outflow pipe of the fluid to be filtered, respectively. Since it is relatively free to swing with respect to the path 5, there is no problem of manufacturing error, and it can be brought into close contact without being caused by individual differences in the dimensions of the filter container 1. That is, in the first embodiment, the second pipeline 6 is disposed inside the wall 2e that forms the first pipeline 5, and the channel hole 2a in the first pipeline 5 is the first pipeline 2. Is formed in a region between the inner side of the wall forming the second pipe 6 and the outer side of the wall 3b forming the second duct 6. And the state which is free to swing means a state in which the distance between the inside of the wall 2e forming the first conduit 5 and the outside of the wall 3b forming the second conduit 6 can be varied.

(Second embodiment)
Hereinafter, the filter container 11 according to the second embodiment of the present invention will be described with reference to FIGS. FIG. 5 shows the filter container 11. FIG. 6 shows the inside of section CC in FIG. Hereinafter, differences from the first embodiment will be described, and the same parts will not be described.

In the first embodiment, the first pipeline 5 is arranged so as to surround the second pipeline 6 inside, but the first pipeline is independently arranged outside the second pipeline. You can also. That is, in the second embodiment, the first pipeline 15 is disposed outside the second pipeline 16. In this case, with the same configuration as the first embodiment, the inner container 13 is held in the outer container 12 so that the inner container 13 is free to swing. Here, in 1st Embodiment, the clearance gap between the holding hole 2b and the 2nd pipe line 6 is located inside the 1st pipe line 5, and arrange | positions so that it may isolate from the 2nd pipe line 6. I was able to. However, in the case of the second embodiment, the gap between the holding hole 12b and the second pipe line 16 is located outside the first pipe line 15, so that from the inside of the outer container 12 It is necessary to restrict the flow of the fluid to the flow path hole 12 a of the first pipe line 15. Therefore, for example, a seal pad 17 made of rubber or resin and having a hole with the diameter of the first pipe line 15 is prepared so as to close the gap between the holding hole 12 b and the second pipe line 16. . The seal pad 17 is arranged on the lower side of the tab 13c so that pressing is applied by the tab 13c. The sealing material 18 is disposed in each of the first pipeline 15 and the second pipeline 16 as in the first embodiment. That is, in the second embodiment, the second pipeline 16 is independently arranged outside the wall forming the first pipeline 15. The flow path hole 12 a through which the fluid flows in the first pipe line 15 is formed inside the wall 12 e that forms the first pipe line 15.

In the second embodiment, it is necessary to seal the gap between the holding hole 12b and the second pipe line 16 with the seal pad 17, but when the first pipe line 15 and the second pipe line 16 are joined together. In addition, since the second pipe line 16 is free to swing relative to the first pipe line 15, there is no problem of manufacturing errors, and the second pipe line 16 does not depend on individual differences in the dimensions of the filter container 1. Will be able to. In the second embodiment, free peristalsis means that the distance between the outer wall surface of the first pipeline 5 and the outer wall surface of the second pipeline 6 varies.

(Third embodiment)
Hereinafter, with reference to FIG. 7 and FIG. 8, the filter container 21 in 3rd embodiment of this invention is demonstrated. FIG. 7 shows the filter container 21. FIG. 8 shows the inside of section DD in FIG. Hereinafter, differences from the first embodiment will be described, and the same parts will not be described.

In the first embodiment, the flow path hole 2 a is arranged in the outer container 2. However, it can also be placed in the inner container. That is, in the third embodiment, the outer container 22 does not have a lid member, and the tab 23c protrudes greatly from the wall surface 23b of the second duct 6 of the inner container 23 and functions as a lid member. A claw for holding the tab 23 c is disposed inside the outer container, and the tab 23 c is held so as to prevent the opening of the outer container 22. The tab 23c is not completely fixed and is held freely swingable. In addition to the flow path hole 23 a of the second pipe line 26, the inner container 23 has a flow path hole 23 f disposed in the tab 23. The channel hole 23f has the same function as the channel hole 2a of the outer container 2 in the first embodiment. Also in this embodiment, since the flow path 23d is located inside the first pipeline 25, the gap between the tab 23c and the outer container 22 is equal to the cross-sectional area of the first pipeline 25. Since a part is formed, it has the same form as the first form as an effect.
