Description

[Detailed Description of the Invention] This invention relates to a filtration filter device used to obtain purified or pure water such as drinking water.

Generally, it is used to obtain drinking water in places without water supply facilities, or when obtaining drinking water using seawater, river water, etc. in the event of an emergency disaster, or for chemical experiments in factories, precision industries, etc. BACKGROUND ART In the case of obtaining pure water, various water treatment filter devices have been used.

Among conventional filtration filter devices, multi-stage devices are constructed by connecting a plurality of independent filters in series in multiple stages, and filter raw water in multiple stages to remove inorganic salts, organic substances, contained gases, etc. The purpose was to remove impurities and obtain pure water.

However, the conventional structure in which a plurality of independent filters are connected in a multi-stage manner has drawbacks such as the large size of the device, space problems, and complicated maintenance and inspection. Ta.

The present invention has been made to eliminate such drawbacks of conventional filtration filter devices, and consists of providing a partition wall inside the main body of the device to concentrically form a plurality of independent filtration chambers, and placing a filter element in each filtration chamber. The object of the present invention is to provide a filtration filter device that is compact and easy to maintain and inspect.

The present invention will be described in detail below based on Examples. FIG. 1 is a longitudinal cross-sectional view of one embodiment of the filtration filter device of the present invention, and FIG.

2 is a cylindrical casing constituting the outer wall of the main body, and 2 is a lid of the casing. 3 is a cylindrical partition provided inside the casing 1, and is arranged concentrically with the casing 1. A first filtration chamber 4 is formed between the partition wall 3 and the inner wall of the casing 1, and a second filtration chamber 5 is formed inside the partition wall 3. A connecting conduit 6 for communicating the first filtration chamber 4 and the second filtration chamber 5 is connected to the lower end of the partition wall 3, and the tip 6' of the conduit 6 is connected to the upper part of the second filtration chamber 5. It is arranged so that it opens at.

Filter element support members 7 and 8 each having a plurality of filtrate passage openings 7' and 8' are installed in a watertight manner in the lower part of each of the filtration chambers 4 and 5. 8, there are pipe-shaped filter elements 9, 9, ... with inner hollow parts 9',

A sealing plate fixed with a pressing plate with a spring (not shown) allows untreated water to pass through the filter elements 9, 9...
This is to prevent direct penetration into the hollow parts 9', 9'.... Reference numeral 14 denotes a sealing lid portion attached to the upper end of the cylindrical partition wall 3 for separating and sealing the second filtration chamber 5 from the first filtration chamber 4. In addition, a first
An inlet 15 for introducing raw water into the filtration chamber 4 is provided, and on the other hand, an inlet 15 is provided on the outer side of the lower end of the casing 1 to take out the filtered water, which communicates with the annular confluence section 12 of the second filtration chamber 5. An outlet port 16 is attached for this purpose.

In the filtration filter device configured as described above, in order to perform a filtration process on raw water, the raw water to be treated is first introduced into the first filtration chamber 4 through the inlet 15. The raw water introduced into the first filtration chamber 4 fills the outer peripheral part of each filter element 9, and is filtered by passing from the outer peripheral surface of each filter element 9 toward its hollow part 9'. is the hollow part 9'
from there to the confluence section 11.

Next, it is filtered in the first filtration chamber 4 and flows into the confluence section 11.
The primary treated water collected in is led to the upper part of the second filtration chamber 5 through the connecting conduit 6. Second filtration chamber 5
, the primary treated water is filtered again in the same process as in the first filtration chamber 4 by the filter elements 9, 9, etc. arranged in the same chamber, and then flows into the second filtration chamber confluence section 12. Can be collected. Then, this secondary treated water is taken out from the outlet 16,
It is now available for use. In this two-stage filtration process using the first and second filtration chambers, impurities such as inorganic salts and organic substances contained in the raw water are removed.

In the above embodiment, the casing and the partition wall are cylindrical, but they are not limited to the cylindrical shape.
Various shapes can be used. Also,
Although one partition wall is provided to form two filtration chambers to perform two-stage filtration processing, it is also possible to provide two or more partition walls and perform filtration processing in three or more stages.

As described above in detail based on the embodiments, the present invention provides a partition wall in the main body of the device to concentrically form a plurality of independent filtration chambers, and arranges a filter element in each filtration chamber for filtration. A compact multi-stage filter device can be obtained by constructing a filter device. In addition, since the filtration chambers are arranged concentrically, the outer filtration chamber is inevitably larger than the inner filtration chamber, but raw water is introduced into the outer filtration chamber, which serves as the first stage filtration chamber. Therefore, the first stage filtration capacity can be increased, and the filtration chambers from the second stage onwards become smaller and the processing capacity becomes smaller.
Since the water is highly purified, even if the filtration capacity is reduced, the filtration process can be carried out satisfactorily. Therefore, by arranging the filtration chambers concentrically in this way, filter elements can be replaced in each filtration chamber at approximately the same time, which is extremely convenient for maintenance and inspection. The effect of this can be obtained.
