Abstract

PURPOSE:To make efficient the installation space and to change the ratio of a filter medium by connecting cartridges packed with the filter medium in parallel by connectors, simultaneously installing a pass closing part and connecting a cartridge packed with a different filter medium in a connector pass in series. CONSTITUTION:A filter consists mainly of active carbon cartridges 11, a hollow yarn cartridge 12 and upper and lower connectors 20, 30 by which the cartridges are connected in parallel from above and below. And fluid to be filtered is caused to flow in from a cap with an inflow port 26 to feed it to a pass 23 of the upper connector 20. At this time, since the pass 23 is closed by a pass closing plate 28, the fluid to be filtered is passed only through the active carbon cartridges 11 to flow in a pass 33 of the lower connector 30. And the primary fluid filtrate filtered by the active carbon is passed through a hollow yarn cartridge 12 and flows in the pass 23 of the upper connector 20 on the outflow port side of the pass closing plate 28. Then, the secondary fluid filtrate filtered by the hollow yarn flows out as it is from a cap with an outflow port 27.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a plurality of filter media to efficiently filter a fluid such as gas or liquid, and in particular, the ratio of the filter media can be easily changed according to the fluid to be filtered. It relates to a filter.

[0002]

2. Description of the Related Art As a filter of this type, filter materials having different filtering performances are filled in cylindrical cartridges, and the cylindrical cartridges are simply connected in series or arranged in parallel. Some are connected in series by piping.

There is also one in which one cylindrical cartridge is filled in advance with two or more kinds of filtering materials having different filtering performances at a predetermined ratio.

[0004]

By the way, in the case where cartridges filled with different filter media are simply connected in series, the cartridge itself extends only in one direction, and therefore the filter itself is bulky and the installation space is not efficient. There is a problem in that the cartridges arranged in parallel are connected in series by piping, and there is a problem that a separate piping space is required and the piping is troublesome.

Further, in the case where one cartridge is filled with two or more kinds of filter media, the entire cartridge must be replaced even if the performance of one of the filter media is deteriorated, which is economically disadvantageous. However, there is a problem that the ratio of the filter medium cannot be easily changed.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a filter which has a high efficiency of installation space, is economical, and can easily change the ratio of a filter medium in order to solve such a problem. is there.

[0007]

In order to solve the above-mentioned problems, a filter according to the present invention comprises a plurality of cylindrical cartridges filled with a filter medium, and a flow path for communicating the cartridges with each other. And a flow path closing member for closing the flow path between the cartridges is detachably attached to one of the connectors, and the flow path closing member is sandwiched between the cartridges. In the connector in which different filtering materials are filled in and the flow path closing member is mounted, an inlet and an outlet of the fluid to be filtered are provided at one end and the other end.

When three or more kinds of filter media are used, a pair of connectors for connecting the cartridges in parallel to each other are alternately provided from one end side to the other end side of the cartridges as described above. A flow path closing member for closing the flow path of is detachably mounted, and the cartridge is filled with different filtering materials with the flow path closing member sandwiched between the one end of the pair of connectors. An inlet for the fluid to be filtered is provided in the connector having the closest channel closing member, and an outlet for the fluid to be filtered is provided at the other end of the pair of connectors in the connector having the channel closing member closest to the other end side. The configuration provided is adopted.

[0009]

With the above-described structure, even though a plurality of cartridges are connected in parallel by a pair of connectors, different filter media are filled by the channels of the connector closed by the channel closing member. The cartridges or groups of cartridges are connected in series.

When changing the ratio of the filter media or the number of kinds of filter media in the filter, the cartridges or cartridge groups filled with the required filter media are sequentially arranged in parallel and connected by connectors, and A flow path closing member is attached to a predetermined position of the flow path.

[0011]

EXAMPLES Examples will be described below with reference to the drawings. As shown in FIG. 1, this filter includes eight cartridges 10 in which a cylindrical body made of a transparent resin is filled with a filtering material, an upper connector 20 for connecting the cartridges 10 in parallel from above and below, and Lower connector 30
And a bolt 41 and a nut 42 that fasten the two connectors 20 and 30 together.

The cartridge 10 comprises six activated carbon cartridges 11 filled with activated carbon and two hollow fiber cartridges 12 filled with hollow fibers 12b.

As shown in FIG. 2, the hollow fiber cartridge 12 is formed by bending a bundle of hollow fibers 12b made of a semipermeable membrane into a U shape so that both end surfaces thereof are aligned with one end of the cylindrical body 12a. The outer peripheral surface of the end portion 12b and the inner peripheral surface of the end portion of the cylindrical body 12a are bonded by a thermosetting resin 12c such as urethane resin to partition the inner and outer ends of the cylindrical body 12a.

Therefore, when a fluid to be filtered such as a liquid or a gas is supplied from the other end side of the opened cylindrical body 12a, it flows through the semipermeable membrane of the hollow fiber 12b into the hollow fiber 12b, and the other of the cylindrical body 12a. It flows out from the end side. At this time, among particles contained in the fluid to be filtered, particles larger than the small holes (0.1 to 0.2 μm) formed in the semipermeable membrane are captured.

The upper connector 20 and the lower connector 3
Reference numeral 0 denotes a resin molded product, and as shown in FIGS. 1 and 4, a tubular body 22, 32 forming a flow path 23, 33 extending linearly in one direction is formed in the central portion of the base portion 21, 31. The flow passage 2 is provided on both sides of the tubular bodies 22 and 32.
The cartridge 10 extending in the direction orthogonal to 3, 33.
The four connection ports 24 and 34 are formed in parallel so as to communicate with the flow paths 23 and 33.

In addition, on both sides of the bases 21 and 31,
Notches 25 and 35 are formed to receive the bolts 41, and male threads 22a and 32a are formed on the outer peripheral surfaces of both ends of the cylindrical bodies 22 and 32, respectively.

A cap 26 with an inflow port and a cap 27 with an outflow port are fitted at both ends of the tubular body 22 of the upper connector 20, and tightening members 26a, 27a are formed at the ends of the tubular body 22. The cap 26 with the inflow port and the cap 2 with the outflow port are screwed into the formed male screw 22a.
7 is fixed.

The tubular body 32 of the lower connector 30
Caps 36, 37 for closing the flow path 33 at both ends of the
(See FIG. 4) is fitted and similarly fixed by tightening members 36a and 37a.

Three pairs of activated carbon cartridges 11 are connected to the connection ports 24 and 34 of the upper connector 20 and the lower connector 30, respectively, from the side of the cap 26 with the inlet, with the flow path 23 interposed therebetween. Then, a pair of two hollow fiber cartridges 12 are connected.

Further, the upper connector 20 and the lower connector 3
0 is connected by tightening bolts 41 having both ends fitted in the notches 25 and 35 with nuts 42 from the upper surface side and the lower surface side of the base portions 21 and 31 via washers 43.

As shown in FIGS. 3 and 4, the flow passage closing plate 28 is attached to the outlet cap 27 via a connecting plate 29.
Are connected to close the space between the activated carbon cartridge 11 and the hollow fiber cartridge 12 in the flow path 23 of the upper connector 20.

In the filter constructed as described above, when the fluid to be filtered is supplied from the inlet cap 26 which is an inlet, the fluid to be filtered flows into the flow path 23 of the upper connector 20. This flow path 23 is formed by the flow path closing plate 28.
Since the space between the activated carbon cartridge 11 and the hollow fiber cartridge 12 is closed, it does not pass through the hollow fiber cartridge 12 and all flows through the activated carbon cartridge 11 into the flow path 33 of the lower connector 30.

[0023] Thus, 1 filtered with activated carbon
The secondary filtered fluid subsequently passes through the hollow fiber cartridge 12 and flows into the outlet side of the channel 23 of the upper connector 20 from the channel closing plate 28, and the secondary filtered fluid filtered by the hollow fibers 12b is discharged. As it is, it flows out from the outlet-equipped cap 27 that is the outlet.

In this case, the ratio between the hollow fiber cartridge 12 and the activated carbon cartridge 11 is 1: 3. However, if this ratio is set to 1: 1, the activated carbon cartridge 11 and the hollow fiber cartridge 11 are mixed as shown in FIG. The four cartridges 12 and the four cartridges 12 are set, respectively, and instead of the cap 27 with the outlet shown in FIG. 4, as shown in FIG.
A cap 27 with an outlet may be used in which the flow path closing plate 28 is located at an intermediate position of the flow path 23.

When using three or more kinds of filter media, as shown in FIGS. 6 and 7, first, the flow path closing member 28 is provided on one end side of the flow path 23 of the upper connector 20 having the inflow port. The lower connector 30,
Alternately, the flow path closing plate 3 such as the upper connector 20.
8 and 28 are mounted, and the end of the flow path of the connector having the flow path closing plate 28 or 38 mounted last is used as the outflow port. Then, the upper connector 20 and the lower connector 30 may be connected to the cartridges 10 filled with different filtering materials by using the flow path closing plates 28 and 38 as a barrier.

[0026]

As described above, in the filter according to the present invention, a plurality of cartridges filled with a filter medium are connected by a pair of connectors having a flow path communicating with each other, and Since the cartridges filled with different filter media are connected in series by attaching the flow path closing member to the filter, the filter itself can be made compact and the installation space can be made efficient. It is very economical because cartridges can be replaced.

Further, since the ratio and the number of kinds of the filter media can be easily changed only by changing the number and the mounting positions of the flow path closing members, it is extremely versatile.
