(First Embodiment)

Hereinafter, a filter container 1 according to a first embodiment of the present invention will be described with reference to FIG. 1. FIG. 1 shows a filter container 1. Fig. 2 shows the inside of section A-A of Fig. 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 made of resin, for example. 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 the fluid to be filtered flows. The outer container 2 has a wall surface formed so as to surround the flow path hole 2 a and protrude from the outer surface of the outer container 2. The outer container 2 includes a holding hole 2b. The holding hole 2b functions to hold the inner container 3 as described later. The outer container 2 may be formed by combining a lid portion 2c and a main body portion 2d having a hollow inside and an opening at one end. For example, the cover 2c must have at least the size to plug the opening of the main body portion 2d, and plug 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 arranged in the cover 2c. The cover 2c and the main body portion 2d are joined, for example, by welding.

The inner container 3 is a chamber having a hollow portion accommodated in 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 the fluid to be filtered flows. Here, the flow path hole 3a is formed. It is an internal section of the second pipe 6 of the elongated pipe. The inner container 3 has a shape in which the second duct 6 projects from the chamber. The inner container 3 is configured such that a part of the chamber is accommodated in the hollow portion of the outer container 2 and the second pipe 6 projects from the holding hole 2b to the outside of the outer container 3. Then, in an area between the outer surface of the wall surface 3b of the second pipe 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, The zoning is formed as the first pipeline 5. That is, for example, the first pipeline 5 and the second pipeline 6 are formed as double pipelines that surround the second pipeline 6 in the first pipeline 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 viewed from the direction of arrow B in FIG. 1. The second tube 6 is attached to the outer peripheral surface and includes ear pieces 3c protruding from the outer peripheral surface. As shown in FIG. 3, the holding hole 2b is provided with a cross section through which the second tube 6 can be inserted, and a cutout through which the ear piece 3c can be inserted is provided in a part. At this time, the size of the holding hole 2b is slightly larger than that of the second pipe 6, and a gap is formed between the second pipe 6 and the holding hole 2b. In the state shown in FIG. 3, the ear piece 3 c and the second pipe 6 pass the holding hole 2 b from the inside of the outer container 2. After passing, the ear piece 3c is rotated 90 degrees along the axis extended by the second tube 6. In this state, since there are no cuts through which the ear piece 3c can pass, the ear piece 3c is caught by the cover 2c of the outer container and cannot be pulled out of the second pipe 6. That is, the inner container 3 cannot be detached from the lid 2c and is held. The inner container 3 keeps the inner container 3 to the lid 2c in a freely swinging state by a gap between the outer peripheral surface of the second pipe 6 and the holding hole 2b. Flow path hole 2a and holding hole 2b are typically arranged 在 盖 2c。 In the cover 2c. As described above, the joining by welding of the cover 2c and the main body portion 2d is performed after the second pipe is held through the holding hole 2b of the cover 2c. Thereby, the inner container 3 is maintained in a freely swinging state in the outer container 2.

A filter member 4 is arranged inside the chamber of the inner container 3. The inside and outside of the chamber penetrate from the position where the filter member 4 is arranged to the outside, and the fluid to be filtered reaches the filter member 4 through the flow path hole 3a of the second pipe 6, and then flows out to the outside of the inner container 3. That is, the inside of the outer container 2. The fluid flowing out of the inside of the outer container 3 is discharged from the first pipe 5 through the flow path hole 2a. The fluid to be filtered can also flow in reverse. In addition, although the filter member 4 is arrange | positioned inside the inner container 3 here, it may not be arrange | positioned inside the inner container 3, but may be arrange | positioned inside the outer container 2. As long as it is arranged in the path through which the fluid to be filtered flows, it can be held in at least one of the outer container 2 and the inner container 3.

For example, the first pipeline 5 is connected to an outflow pipeline flowing out of the fluid to be filtered, and the second pipeline 6 is connected to an inflow pipeline flowing into the fluid to be filtered. However, the first line 5 may be connected to an inflow line flowing into the fluid to be filtered, and the second line 6 may be connected to an outflow line flowing out to the fluid to be filtered. That is, when the filter container 1 is installed in the filtering device, either of the first pipe 5 and the second pipe 6 is connected to the inflow pipe of the filtering device, and the other is connected to the outflow pipe of the filtering device. A flow circuit of a fluid flowing from the inflow pipeline through the filter member 4 to the outflow pipeline is formed. As shown in FIG. 2, a sealing material 8 is arranged at a joint portion with the inflow pipe. FIG. 2 is connected to the inflow pipeline outside the second pipeline 6 But they may be joined inside the second pipe 6. On the other hand, the first line 5 is connected to an outflow line from which the fluid to be filtered flows. As shown in FIG. 2, a sealing material 7 is arranged at a joint portion with the outflow pipe. FIG. 2 is connected to the inflow pipe outside the first pipe 5, but may be connected to the inflow pipe inside the first pipe 5. Inside the first pipe 5, there are an inflow hole 2a and a holding hole 2b. The gap between the holding hole 2b and the second pipe 6 is not only isolated from the second pipe 6, but also functions as a flow path of the first pipe 5. Therefore, in the filtering device, when the inflow pipe and the outflow pipe of the fluid to be filtered are connected to the first pipe 5 and the second pipe 6, respectively, the second pipe 6 is also opposed to the first pipe 5 Since it is relatively free to shake, 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 tightly sealed. That is, in the first embodiment, the second pipe 6 is disposed inside the wall 2e forming the first pipe 5, and the flow path hole 2a of the first pipe 5 is formed in the first pipe 2. The area between the inside of the wall and the outside of the wall 3 b forming the second duct 6. Then, the state of free shaking means that the distance between the inside of the wall 2e forming the first pipe 5 and the outside of the wall 3b forming the second pipe 6 is variable.
