Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a filtering device.

[Prior Art] As shown in FIG. 4, inside a body 1, a primary chamber 2 for containing a stock solution for filtration and a secondary chamber 3 for taking out a filtered solution are vertically arranged via a partition wall 4. A filter device is known in which a plurality of filter blocks 5 are formed in compartments and are filtered in the primary chamber 2 to supply the undiluted solution to the secondary chamber 3.

In such a filtering device, an inlet 6 for the undiluted filtered solution and an outlet 7 for the filtered solution are provided on the sides of the primary chamber 2 and the secondary chamber 3, respectively. Since 3 and 3 are located at different heights, the entrance 6 and the exit 7
Cannot be installed at the same height, and when connecting the feed pipe for the filtered raw liquid and the take-out pipe for the filtered liquid to the inlet 6 and the outlet 7, these pipes are conveniently installed at the same height in the filtering device. There was the inconvenience that even if I wanted to connect, the connection would be difficult. Moreover, cleaning the inside of the body 1 is very troublesome, and in particular, it is almost impossible to completely clean the inside of the secondary chamber 3 closed by the partition wall 4, so that the dust generated during the manufacturing process remains unchanged. There is also a drawback that it remains in the secondary chamber 3 to lower the filtration accuracy.

[Problem to be Solved by the Invention] An object of the present invention is to provide a filtration device that has an inlet for a filtered stock solution and an outlet for a filtered solution in the same plane and is easy to clean the inside.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides
A primary chamber for accommodating the filtered stock solution and a secondary chamber for taking out the filtered solution are divided into upper and lower sections through a partition wall, and a filter block for filtering the undiluted solution and supplying it to the secondary chamber is provided in the primary chamber. In the installed filtering device, the body is formed by a separable lower container and an upper cover, and the lower container is formed in a dish shape with an open upper surface, and the side surface of the lower container has an inlet for filtered stock solution and a filtered solution. And a partition plate that partitions the interior of the container into a first region that communicates with the inlet and a second region that communicates with the outlet, and that forms a partition wall on the upper surface of the second region. By being detachably attached, a primary chamber communicating with the inlet through the first region is formed inside the upper cover, and a secondary chamber communicating with the outlet is formed inside the lower container.

[Operation] The filtration device is used by connecting the supply pipe for supplying the filtered stock solution to the inlet and the outlet and the take-out pipe for taking out the filtered liquid, respectively. The inlet and the outlet are provided on the same straight line so as to face each other. Therefore, both pipes can be arranged at the same height or on the same straight line.

The filtered stock solution supplied from the inlet flows into the primary chamber through the first region, is filtered by the filter block, then flows into the secondary chamber, and is taken out from the outlet as a filtered liquid.

The filtration device is washed with the upper cover and the lower container separated, and the partition plate removed from the lower container.
As a result, the primary chamber and the secondary chamber are completely opened, so that the inside can be easily cleaned without removing the pipes at the inlet and the outlet.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

In the first embodiment shown in FIG. 1, reference numeral 10 denotes a body of a filtering device, which includes a lower container 11 and an upper cover 12.
And the flange portions 11a and 12a are detachably connected to each other by a V-band 13, and a primary chamber 14 for accommodating the filtered stock solution and a secondary chamber 15 for taking out the filtered solution are contained therein. A plurality of filter blocks 16 are provided in the primary chamber 14 to filter the stock solution for filtration and supply it to the secondary chamber 15. 17 is a packing and 18 is an air vent.

As can be seen from FIG. 2, the upper and lower containers 11 have a shin dish shape with an open upper surface, and the inlet 20 of the filtered stock solution and the outlet 21 of the filtered solution are located on the same surface on the side surfaces thereof. The partition wall 22 divides the interior thereof into a narrow first region 23 communicating with the inlet 20 and another second region 24 communicating with the outlet 21, and the primary region is provided on the upper surface of the second region 24. A partition plate 25 as a partition for partitioning the chamber 14 and the secondary chamber 15 is detachably attached by a bolt 26, whereby the primary chamber communicating with the inlet 20 through the first region 23 inside the upper cover 12. 14
However, the secondary chambers 15 communicating with the outlets 21 are formed in the second regions 24 inside the lower container 11, respectively. In addition, 27 is packing and 28 and 29 are drain ports.

The filter block 16 disposed inside the primary chamber 14
Is a cylindrical filter element 31 made of a filter medium.
And a support pipe 32 having an opening on the side surface inserted into the hollow portion of the filter element 31, the lower end of the support pipe 32 being secondary to the cylindrical holder 33 mounted on the partition plate 25. A holding cap that is supported in a state of communicating with the chamber 15, seals the upper end of the support pipe 32, and holds the filter element 31 between the holder 33 and the holder 33.
34 is attached, and the holding cap 34 is pressed by the holding plate 36 attached to the center bolt 35 at the center of the partition plate 25 via the coil spring 37, so that each filter block 16 is placed in the primary chamber 14. It stands upright so that it can be replaced. Then, the unfiltered solution in the primary chamber 14 is filtered by passing through the filter element 31, and then flows into the support pipe 32 through the side opening, and flows down the support pipe 32 into the secondary chamber 15. It is like this.

Incidentally, 38 is a wing nut for adjusting the position of the pressing plate 36.

The filtering device having the above-described configuration is used by connecting the supply pipe for supplying the stock solution for filtration to the inlet 20 and the outlet 21 and the pipe for taking out the filtered liquid, respectively, but the inlet 20 and the outlet 21 are in the same plane. Since it is provided, even if there is a constraint that both pipes must be arranged at the same height or on the same straight line, it is possible to surely cope with them.

Here, the filtered stock solution supplied from the inlet 20 is the first region 23.
Through the primary chamber 14 through the filter element 31 is filtered and flows into the support pipe 32,
After flowing down the support pipe 32 and flowing into the secondary chamber 15, it flows out from the outlet 21 as a filtered liquid.

The filtration device is washed with the upper cover 12 and the lower container 11 separated from each other and the partition plate 25 removed from the lower container 11. As a result, the primary chamber 14 and the secondary chamber 15 are completely opened, so that the inside can be easily cleaned without removing the pipes of the inlet 20 and the outlet 21.

The second embodiment shown in FIG. 3 is a case where a high precision filter element such as a membrane is used. The structure of the filter block 16 and the mounting method of the filter block 16 are different from those of the first embodiment. Since only the difference is made and the other configurations are substantially the same, only the different portions will be described below, and the other common portions will be described in the first section.
The same reference numerals as those in the embodiment are attached and the description is omitted.

That is, the filter block 16 includes a pleat-type filter element 41, a porous inner cylinder 42 and an outer cylinder 43 that hold the filter element 41, and the inner cylinder 41 and the outer cylinder 42.

And an annular lower end plate 45 that joins the lower ends of the inner cylinder 42 and the outer cylinder 43, and the cylindrical portion 45a of the lower end plate 45 has a cylindrical holder 4 integrally formed with the partition plate 46.
7 is inserted through O-ring 48, and upper end plate 4
A press plate 50 loosely fitted to the center bolt 49 is directly brought into contact with the upper part of the filter 4, and the press plate 50 is pressed by a wing nut 52 via a coil spring 51.
Are held upright. The packing 27 between the partition plate 46 and the lower container 11 is made by punching out a fluororesin sheet to improve durability and chemical resistance and suppress dust generation. Further, the surfaces of the partition plate 46 and the lower container 11 are made smooth by polishing the portions in contact with the fluid.

Since the operation of the second embodiment is the same as that of the first embodiment, its description is omitted.

[Effect of the Invention] As described above, according to the present invention, since the inlet of the unfiltered solution and the outlet of the filtered solution are formed on the side surface of the lower container so as to face each other on the same straight line, the inlet and the outlet are filtered. When connecting the supply pipe for the stock solution and the take-out pipe for the filtered solution, both pipes can be surely connected at the same height or on the same straight line.

In addition, when cleaning the filtration device, the upper chamber and the lower chamber can be separated and the partition plate can be removed from the lower chamber to completely open the primary chamber and the secondary chamber. It is possible to easily and surely clean the inside without removing the.
