BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a disposable unit container in which a filter medium is housed and integrated.

[0002]

2. Description of the Related Art For filtering liquids such as paints and inks, generally, a container containing one or a plurality of cylindrical cartridge filters is connected to a pipe for a liquid to be purified and directed from the outside to the inside of the filter. Liquid is allowed to pass through, and contaminants and aggregates of particles are captured and purified.
The type of filter and the number of stages of filtration are determined according to the required filtration level. Therefore, in the production line, the combination of the type and the number of cartridge filters in the unit container is changed according to the purpose of filtration and the required flow rate.

[0003]

The unit container is a consumable item and must be promptly replaced with a new one at the end of life of one unit. However, a resin molded body such as polypropylene or polyethylene is used, and therefore, dimensional accuracy and shape stability become problems, and problems such as liquid leakage are likely to occur. The object of the present invention was made in view of the above circumstances, and the object is to:
Hold firmly according to the shape of the cartridge filter,
Moreover, it is to provide a shape of a unit container suitable for liquid distribution and smooth passage thereof.

[0004]

The above object of the present invention comprises a sheath having a pressure-resistant and durable structure and a unit container housed in the sheath and containing one or more cartridge filters. In a heavy-duty filter container, a cylindrical cartridge stripper that individually covers the upper ends of the individual cartridge filters contained in the unit container and is fitted to the inner hole end of the cartridge filter, and a cartridge outside the cartridge stripper An upper end cap having a ring-shaped sealing edge that seals the end face of the filter, and a cylindrical shape that fits on the inner hole end of this cartridge filter corresponding to the position and the required number of each cartridge filter on the same plane. A ring-shaped seal edge that seals the end face of the cartridge filter with the cartridge stopper and its outside. And a bottom end cap having one as a component, the one or more cartridge filters corresponding to the number of cartridge filters, and an end plate having a common bottom end. This is achieved by a filter container that can be fixed in the unit container by holding it from above and below with a cap. Still another object of the present invention is that the bottom end cap is fitted with a fitting groove provided in the lower portion of the bottom end cap to a partition wall provided at the base of the container to integrate the base end with the liquid introducing portion and the liquid discharging portion. This is achieved by a filter container that is characterized by separating the parts.

[0005]

The bottom end cap is fixed to the body of the container, the cartridge filter is positioned by the cartridge stopper, and the cartridge filter is sandwiched between the bottom end cap and the upper end cap supported on the upper surface of the container through the cushion material. At the same time as fitting the cartridge stopper to the inner hole end of the cartridge filter,
By pressing the ring-shaped seal edge onto the end face, short circuit of liquid is prevented.

Further, by fitting and integrating the bottom end cap and the partition wall provided at the base, the unfiltered liquid that has flowed in from the liquid introduction hole and the purified water that has passed through the cartridge filter and is discharged into the discharge hole. It also has the function of clearly distinguishing the flow paths of the guided liquids and preventing their mixing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings.
FIG. 8 is an assembly explanatory view of the double structure filter container, and FIG. 9 is a vertical cross-sectional view (four filters) of the assembled double structure filter container. A metal sheath having a permanent pressure resistant structure is divided into a pedestal 1 and a cap portion 2, which are integrated by a flange 3, a screw or a clamp or other coupling means. The pedestal 1 has a liquid introduction pipe 4 and a liquid discharge pipe 5
Are provided, and the outer sides of these pipes are directly connected to a purification process line (not shown). The unit container 6 has a cartridge filter 7 built-in and a liquid inlet 8 at the bottom.
And a liquid discharge port 9 and closing valves 10 and 11 for closing the respective holes from the inside when the container is not set. When assembling, first, the cap portion 2 is removed from the pedestal 1 and the liquid introduction pipe 4 is attached to the liquid introduction port 8 and the liquid discharge port 9.
After the unit container 6 is set on the pedestal 1 by fitting the liquid discharge pipe 5 and the liquid discharge pipe 5, respectively, the cap portion 2 may be put on the unit container 6 and coupled to the pedestal 1.
At this time, the shutoff valves 10 and 11 are pushed up by the liquid introduction pipe 4 and the liquid discharge pipe 5, respectively, so that the liquid flow path is opened.

FIG. 1 is a vertical cross-sectional view (in the case of seven cartridge filters) showing an embodiment of the unit container of the present invention. Since the cartridge is disposable, the entire product is a plastic molded product from the economical viewpoint. . Therefore, it is not of a pressure resistant structure itself, but is protected by a sheath portion to supplement it. As a material, it is preferable to use a material having flexibility to some extent rather than a hard and brittle material, for example, a molded body of polyolefin resin or the like. As can be seen from FIG. 1, the housing of the unit container 6 has a body portion 13 in the upper part for accommodating the cartridge filter 7, and a base portion in the lower part for partitioning / distributing the inflowing undiluted solution and the filtered solution with the partition wall 21. It is composed of 14 and.

The upper end cap 16 is a cushion material 1.
The upper end of the cartridge filter 7 is supported by the upper surface of the body portion 13 via 5 and the end surface is shielded. 2 is a bottom view of the upper end cap, and FIG. 3 is a sectional view taken along line XX 'of FIG. 3, in which a cylindrical cartridge stopper 17 that fits into the inner hole of the cartridge filter is formed on the lower surface of the disk-shaped shield plate.
And a plurality of ring-shaped seal edges 18 that are concentric circular protrusions provided on the outside thereof. The bottom end cap 19 has a strip-shaped fitting portion 2 provided on the bottom surface thereof.
It is fixed at a predetermined position by fitting 0 to the upper edge of the partition wall 21 in the base portion 14 of the unit container, and the lower end of the cartridge filter is supported by the cartridge stopper 22 and the seal edge 23 provided on the upper surface.

FIG. 7 is a sectional view taken along line YY ′ of FIG. In addition, FIG.
[Fig. 3] is a sub-sectional view of a unit container to which the bottom end cap is attached. As is clear from FIG. 4 or FIG. 6, the bottom end cap 19 has seven holes that communicate with the seven inner holes of the cartridge filter.
The fitting portion 20 is formed in a loop shape by including these holes inside. Thus, as shown in FIG. 1, the bottom end cap 1
9 also plays a role of partitioning the filtered liquid together with the partition wall 21 from the undiluted liquid to the liquid discharge hole 9. The reason why the outer peripheral portion of the bottom end cap has a plurality of cutouts is to make the passage of the liquid smoother, and the stock solution flowing in from the liquid inlet 8 flows from the partition outside the partition wall 21 to the bottom end cap. It is guided to the outer surface of the cartridge filter in the body portion 13 through the outer peripheral portion. Further, FIGS. 4 and 5 show a ring-shaped guide 26 that supports one end of the shut-off valve 10 and the positioning fitting pin 25 when fitted to the base portion 14.

The above-mentioned unit container is set from the parts as follows. That is, first, the required cartridge filter having the upper end cap attached is fixed to the cartridge stopper of the bottom end cap, and then the upper edge of the partition wall 21 and the band-shaped fitting portion 20 are guided by the positioning fitting pin 25. Bottom end cap 1 corresponding to the required filter size and number on the base 14 by fitting with
Fix 9 At this time, the shutoff valves 10 and 11 are fixed at one end at predetermined positions. Finally, the body portion 13 is covered from above, and the cushion material 15 is pressed down from above to be united with the base portion 14.
