Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a liquid purifying device with a removable filter member.

An example of a liquid cleaning device is a dry cleaning liquid cleaning device shown in FIG. In this liquid cleaning device, a cylindrical filter member 3 is fitted into a liquid drain pipe 2 in the center of a sealable cylindrical container 1, and a cleaning liquid (dry cleaning liquid) introduced from an inlet 4 is passed through the filter member 3 and drained into the center. The cleaning liquid is taken out from a liquid pipe 2, and contaminants, dust, etc. contained in the cleaning liquid are removed by a filter medium 5 and an adsorbent 6. In this liquid purifying device, the filter medium 5 may become clogged with dust or the like, and the adsorbent 6 may become saturated, so the filter member 3 must be periodically removed and cleaned.

However, in this liquid purifying device, it is necessary to increase the surface area of the filtration material as much as possible in order to increase the filtration capacity, so it is common to form the filtration member 3 to be slightly smaller than the inner diameter of the container 1. be. For this reason, the gap between the container 1 and the filter member 3 becomes narrow, making it difficult to remove the filter member 3. In addition, when the filter member 3 becomes large and heavy, the removal operation of the filter member 3 becomes even more difficult.

Of course, the same applies not only to devices that clean dry cleaning liquids, but also to devices that clean various drainage liquids, drainage water, used liquids, etc. that have a structure in which a cartridge-type filtration member is loaded into the container. I can say that.

The purpose of the present invention is to provide a liquid purifying device in which the filter member can be easily taken out, and is provided with a contact plate at one end that contacts the rear end surface of the filter member, and the other end is bent in front of the front end surface of the filter member. This is achieved by providing a pull-out rod with a flexible handle.

The configuration of the present invention will be described in detail below based on an embodiment shown in the drawings.

FIG. 2 shows an embodiment of the liquid purifying device according to the present invention in a central vertical sectional view. This liquid cleaning device cleans dry cleaning liquid, and a cylindrical filter member 1 is connected to a drain pipe 11 in the center of a cylindrical container 10.
2, and the dry cleaning liquid introduced from the inlet 13 is taken out from the drain pipe 11 through the filter member, thereby removing contaminants, dust, etc. in the dry cleaning liquid, which is the cleaning liquid, in the filter medium 14 of the filter member 12 and the adsorbent 15. It is to be removed.

The cylindrical container 10 has a lid 16 that can be opened and closed, and is kept in a sealed state during operation. A drain pipe 11 that communicates the inside and outside of the container is fixed in the approximate center of the container 10 in the longitudinal direction (axial direction). Drain pipe 1
1 is for letting the dry cleaning liquid flow in through a hole 17 on the circumferential surface and discharging it outside the container 10, and has a bolt 18 at the tip for fixing the filter member 12, and the filter member 12 is fixed to the container 10. It also serves as a support for fixing it inside 10. The container 10 is of a horizontal type and has an inlet 13 and a hole 19 at the top for venting air. Although not shown, a pressure gauge is attached to this hole 19. Additionally, a filter member 12 is provided at the bottom of the container 10.
In order to facilitate the insertion and removal of the filter member 12, two guide rails 20 are provided to support the filter member 12. For the guide rail 20, a round bar or circular tube is used to reduce the sliding resistance of the filter member 12.

Filtering member 12 accommodated in the cylindrical container 10
is a porous inner cylinder 2 having flanges 21 at both ends.
2 and the filter medium 14 constituting the outer cylinder.
It is filled with dry cleaning liquid and is configured to allow the dry cleaning liquid to pass through it in the radial direction. The filter medium 14 is preferably a filter paper or a filter cloth folded back into a chrysanthemum shape and attached with walls to increase the surface area, but is not limited thereto. Also,
As the adsorbent 15, activated carbon, alumina, zeolite, silica gel, etc. are used. This filter member 12 is fitted into the drain pipe 11 with a packing 23 interposed in the flange 21 portion and fixed with a presser foot 24. Therefore, all the dry cleaning liquid introduced into the container 10 passes through the filter member 12 and is discharged from the drain pipe 11. Note that the reference numeral 31 is a handle nut.

A pull-out rod 25 is provided in the gap between the filter member 12 supported by the guide rail 20 and the container 10. The pull-out rod 25 has at one end a contact plate 26 that comes into contact with the rear end surface of the filter member 12, and at least a handle 27 that is bendable in front of the front end surface of the filter member 12 at the other end. In this embodiment, since two filter members 12 are used, the main body 28 is composed of two rods having approximately the same length as the filter members 12, and these are connected with a pin 29. Therefore, it is provided so that it can be bent. In this case, after taking out the filter member 12 on the near side, the main body portion can be bent to substantially shorten the length of the pull-out rod 25, so there is no need to take up a large working space in front of the liquid purifying device. In the drawer rod 25 of this embodiment, the handle 27 is also bendably connected to the main body 28 with a pin 30.

In the liquid purifying device configured as described above, the filtering member is removed and installed in the following manner.

First, after completely draining the cleaning liquid (dry cleaning liquid), the lid 16 of the container 10 is opened. Next, the handle 27 of the pull-out rod 25 is folded down to straighten the pull-out rod 25. Then, the nut 31 is loosened and the presser foot 24 that tightens the filter member 12 is removed from the drain pipe 11. Thereafter, the handle 27 of the pull-out rod 25 is pulled to pull out the filter member 12. Since the filter member 12 is supported by the guide rail and is in a state where it can easily slide, the filter member 12 can be moved against the contact plate 2 of the pull-out rod 25 with a slight force.
It can be easily taken out by scraping it out by 6.

When installing a new or cleaned filtration member 12, the pull-out rod 25 is housed in the container 10 in advance, or the abutment plate 26 is set so as to come into contact with the rear end surface of the filtration member 12, and the filtration member 12 is removed. 12 at the same time as the insertion. Thereby, the filter member 12 is set in a state where it can be taken out simply by pulling the pull-out rod 25. The filter member 12 is fixed using a rear presser foot 24 installed in the container 10 so as to fit into the drain pipe 11. after that,
Pull up the handle 27 of the pull-out rod 25 and close the lid 16.

As is clear from the above description, the present invention accommodates a cylindrical filtration member in a container having an inlet and a drain port, and cleans the cleaning liquid introduced into the container through the filtration member when being discharged. In the liquid purifying device, one end is provided with a contact plate that contacts the rear end surface of the filtration part, and the other end is provided with a pull-out rod having a bendable handle in front of the front end surface of the filtration member, so that the pull-out rod can be pulled. You can easily and easily take out the filter member by just pressing the button. Furthermore, the present invention allows the handle of the drawer bar to be bent, so it does not take up much space when stored.
