Description

Variable filter filtration device {Filtration device having variable filter}

The present invention relates to a variable filter filtration device, and more particularly, by horizontally stacking unit filters to form a filter stack, washing efficiency is remarkably improved as the unit filters are separated from each other by the pressure of the washing water during backwashing. It relates to a variable filter filtration device as possible.

Water is widely used for various purposes in general living environments and industrial sites. Accordingly, there is a trend that the application range of water purification technology is expanding. In particular, in the treatment of household water, sewage, medicine, semiconductor water, cooling water, etc., a rapid filtration treatment method that promotes a water pressure difference is widely used.

In general, in a water purifier, a pre-treatment filter is used to remove relatively large foreign substances such as rust residue from the pipe, and then a carbon filter using adsorption of activated carbon, a reverse osmosis membrane filter, a hollow fiber membrane filter, a sterilizing ceramic filter, etc. are used. Water purification proceeds through the process of filtering out bacteria or heavy metals that adversely affect health while preserving minerals as much as possible for drinking. Or, in the case of water used for washing products in industrial sites, if the washing water is contaminated, in order to prevent recontamination of the product during the product washing process, a pretreatment filter is also used to remove foreign substances from the water. After that, if necessary, it is used as it is or filtered using another filter to make it suitable for washing water.

As described above, filtration processes for water purification are also varied depending on the purpose, and the types of filters used are also diverse, but in any case, a pretreatment filter that primarily filters foreign substances is required. Of course, an example of purified water has been described above, but in the case of filtering various fluids such as oil, chemicals, steam, and the like, a pretreatment filter for removing foreign substances as described above is required.

As described above, a pretreatment filter for removing foreign substances in a fluid is mostly required in any filtration process (including a water purification process). In general, as the material of the pretreatment filter, a porous material is used so that particles larger than a predetermined size can be filtered out and fluid can escape, for example, non-woven fabric or ceramic.

It is well known that the foreign matter removed in the process of removing the foreign matter as described above eventually accumulates in the pretreatment filter, and thus the filtration function deteriorates the longer the pretreatment filter is used. Accordingly, in most devices, in general, the pretreatment filter is replaced every predetermined period and used. However, there is a problem in that time, manpower, and cost are wasted because the pretreatment filter must be frequently replaced.

Accordingly, the applicant of the present invention in Korea Patent Registration No. 10-1193206 to use the filter semi-permanently, a scratch (S) is formed on the surface and a stainless steel disk filter that is formed by bending a predetermined angle in the upper or lower direction, a stainless steel disk filter stacked. Developed.

The stainless steel disk filter of Korea Patent Registration No. 10-1193206 is filtered by flowing fluid in the forward direction while the stainless steel disk stack is compressed, and when the fluid flows in the reverse direction, the compression of the stack is released so that each stainless disk is As the bent initial shape is restored, the gap is widened to provide a structure that facilitates backwashing of foreign matter.

However, the aforementioned Korean Patent Registration No. 10-1193206 discloses that when used for a long time, the bending angle of each stainless steel disk stacked in the vertical direction gradually decreases due to the influence of gravity. As it becomes narrower, there is a problem that the backwashing efficiency is deteriorated.

Hereinafter, an operation of the variable filter filtration apparatus according to an embodiment of the present invention will be described with reference to the drawings.

4A and 4B are views for explaining the operation of the variable filter filtering apparatus according to an embodiment of the present invention.

First, in order to perform the filtration operation, as shown in FIG. 4A, by driving the compression means 50, the stacked plate 21 of the filter compression unit 20 is moved in the direction of one end of the first housing 10, and the filter The filter stack 30 is pressed through the stacking plate 21 while one side of the unit filter 31 located on the outermost side of the stack 30 is supported by the support cap 42 of the filter support 40 The unit filters 31 of the filter stack 30 are induced to be stacked with each other.

As above, when raw water is introduced into the first housing 10 through the raw water inlet 11a after the unit filters 31 of the filter stack 30 are in a stacked state, the filter stack 30 Floating matter larger than the void formed by the screen mesh 31b between the unit filters 31 of the unit remains in the first housing 10 and passes through the void between the unit filters 31 The filtered treated water flows into the second housing 60 along the moving path R formed inside the filter stack 30, and then flows into the outside of the second housing 60 through the treated water outlet 61a. Is discharged as.

In addition, in order to perform the backwashing operation, the compression means 50 is driven to move the stacking plate 21 of the filter compression unit 20 in the direction of the other end of the first housing 10, In a state in which one side of the unit filter 31 located at the outermost side is released from the state supported by the support cap 42 of the filter support part 40, as shown in FIG. 4B, the second filter through the treated water outlet 61a When washing water flows into the interior of the housing 60, the unit filters 31 constituting the filter stack 30 are separated from each other by the pressure of the washing water flowing from the second housing 60 to the first housing 10. As the stacked state of the filter stack 30 is released, the suspended matter trapped in the screen mesh 31b of each of the unit filters 31 is easily separated from the unit filters 31 by washing water. The suspended matter is discharged to the outside of the first housing 10 through the backwash water outlet 11b together with the washing water.

Although the present invention has been described in connection with the above preferred embodiments, it is possible to make various modifications or variations without departing from the gist and scope of the invention.
