The present invention relates to a technology for drastically improving turbidity by neatly removing black water generated during initial water flow using a PE fine dust filter embedded in a carbon block filter.

In general, a filter installed in a water purifier has a function of filtering out various impurities such as iron, rust, and organic matter contained in tap water, sterilizing bacteria, and inactivating viruses.

Various types of such filters have been proposed, and in particular, the carbon block filter includes the carbon block in the filter container so that the water is introduced into the water passage 2 from the outside to the inside of the water passage 2 as shown in FIG. 5. After passing through the purified water is to be withdrawn through the water exit hole (3a) formed in the upper cover (3).

As the prior art related to the carbon block filter, "Patent Registration No. 907049, Name / Method of manufacturing a high performance granular carbon block filter", which has been filed by the applicant of the present invention and granted a patent decision, has been proposed. The technology uses granular activated carbon and special polymer granular PE binder as a main raw material, and provides a useful effect of compression molding into a granular carbon block filter having a high water flow rate and high filtering power.

However, all other carbon block filters including the prior art have a problem that black water flows out during initial water flow due to the characteristics of activated carbon, which is a main raw material.

Therefore, when used as a filter for a cold and hot water purifier having a separate water reservoir, pollution occurs inside the water reservoir due to the influence of the black water, causing bacteria and microorganisms to grow, as well as valves and cocks, which are peripheral devices of the cold and hot water purifier. It is a cause of failure, such as a situation that leads to consumer complaints, serious customer claims are occurring.

The present invention is to actively solve all the problems of the carbon block filter according to the prior art, the PE ultra-high molecular binder as a main raw material can be compression-molded PE dust filter with a high water flow rate and high filtering power The PE fine dust filter is embedded in the existing carbon block filter to efficiently remove black water generated during initial water passage.

The present invention is to mix the first ultra-high molecular PE binder and the second ultra-high molecular PE binder as a means for solving the above problems, and after filling the mixed raw material in the mold and pressurized by using a compression press fine dust In order to compression molding the filter, and to heat the whole mold and to take out the PE fine dust filter from the cooled mold.

In addition, the present invention seeks a technology for installing the PE fine dust filter in the water outlet formed in the upper cover that is fitted to the top of the existing carbon block filter.

According to the present invention, since the PE fine dust filter is installed in the outlet of the carbon block filter containing activated carbon as a main material, the PE fine dust filter smoothly removes black water generated during initial water passage, thereby dramatically improving turbidity. To provide.

This effectively prevents contamination of the inside of the reservoir, and prevents the growth of bacteria and microorganisms, and provides an effect of improving the customer satisfaction by eliminating defects such as valves and cocks that are peripherals of the cold and hot water purifier.

Hereinafter, the present invention having the above-described schematic configuration will be described in more detail for facilitating the implementation.

First of all, the carbon block filter 10 organically grafted with the PE fine dust filter 20, which is a core technology of the present invention, has a water passage 12 open up and down at an inner center thereof, and an upper end of the water passage 12. An upper cover 13 having a water extraction hole 13a formed therein is fitted therein, and the lower cover 14 is sealed at the lower end of the water supply hole 12 so that the normal water is outside the carbon block filter 10. After flowing into the inner through-hole 12 in and out is discharged to the outside through the outlet hole (13a) of the upper cover (13).

The lower part of the water extraction hole (13a) of the upper cover 13, as shown in Fig. 1 and 2, the PE dust filter 20 is a core technology of the present invention is installed in the inserted state.

Hereinafter, an embodiment and an experimental example of generating the mixed raw material of the present invention for manufacturing the PE fine dust filter 20 by mixing the first ultra high molecular PE binder and the second ultra high molecular PE binder at an appropriate ratio will be described. Let's do it.

① First Example

In a first embodiment of the present invention, the first ultrahigh molecular PE binder having an average particle miciron of 30 microns or less and the second ultra high molecular PE binder having an average particle miciron of 120 microns or less are evenly mixed so as to have a ratio of 7: 3 by weight.

And while performing the above process continuously using the mixed raw material, it is possible to manufacture the PE fine dust filter 20 having a fine supply distribution excellent in turbidity removal ability while ensuring the amount of water that can finally be used for a long time. .

At this time, if the average particle micron is small, it may be more effective to remove the turbidity, but the water flow rate decreases rapidly during use, so that the filter cannot be used for a long time, and also powder forms such as other low-density polyethylene (LDPE) and high-density polyethylene (HDPE). The use of phosphorous polyethylene has a disadvantage in that the amount of water is remarkably reduced. In the present invention, the first ultra-high molecular PE binder and the second ultra high-molecular PE binder having the unique characteristics as shown in Table 2 are excluded and used. .

Meanwhile, the PE fine dust filter 20 completed through the manufacturing process using the main raw material is used for the purpose of effectively removing the black water generated in the carbon block filter 10 during initial water passage. As shown in the inserted into the inner protrusion (13b) formed integrally protruding in the center of the bottom of the upper cover 13 so as to fit in the water hole (12), the water outlet of the upper cover (13) The insertion protrusion 21 to be fitted to the 13a) is formed in a two-stage structure protruding to maintain a more secure coupling state.

In addition, the insertion protrusion 21 further blocks the water extraction hole 13a so that black water does not pass through the PE fine dust filter 20 and the inner diameter portion of the inner protrusion 13b and the PE fine dust filter 20. Even if a leak occurs through a minute gap generated between the insertion protrusions 21 to block the water exit hole (13a) secondary, black water is discharged to the outside through the water extraction hole (13a) Since the efficiency of turbidity removal can be further improved.

In addition, since the insertion guide surface 22 is formed to be inclined at the corner of the insertion protrusion 21 so as to be more smoothly inserted into the water extraction hole 13a, the assembly can be more smoothly assembled.

Further, the upper cover 13 fitted into the water passage 12 has a PE pulverized protruding frame 30 formed on the inner surface of the inner protrusion 13b, so that the PE powder is inserted into the inner protrusion 13b in an inserted state. By enclosing the jin filter 20 wrapped around the blotting protruding frame 30, the PE fine dust filter 20 does not deviate to the outside and maintains a more rigid fixed state, as well as a certain airtightness, so that the black water is external. To prevent leakage efficiently.

② Experimental Example

The carbon block filter 10 having the PE fine dust filter 20 manufactured according to the present invention was mounted in a cold water purifier, and the turbidity of water passing through the cold and hot water purifier was measured, and the PE fine dust filter 20 of the present invention was measured. The turbidity of the water passing through the cold / hot water purifier equipped with only the ordinary carbon block filter 10 having no internal component) was measured.

The measured values are as shown in Table 3 below.

That is, according to the present invention, due to the characteristics of activated carbon which is the main raw material of the carbon block filter, the black dust generated during the initial water flow is effectively removed by the PE fine dust filter 20 embedded in the fitted state below the water extraction hole 13a.
