Description

  The present invention relates to a natural filtration type water purifier cartridge in which filter tubes with built-in filter media are stacked one above the other, and the raw water is moved through the filter tubes to be filtered and discharged. By providing a supply pipe perpendicularly to the inner center of the filter cylinder, the raw water is supplied to the lower part of the filter cylinder and is filtered and discharged by the filter medium while being guided from the lower part to the upper part. The present invention relates to a natural filtration type water purifier cartridge that maximizes filtration efficiency.

In general, as shown in FIG. 1, the cartridge 3 installed in the natural filtration water purifier is installed between the raw water bottle 1 and the water purification pipe 2, and filters the raw water that naturally falls from the raw water pipe into the water purification pipe. collect.
As shown in FIG. 2, such a cartridge 3 is configured by stacking and joining an upper filter cylinder 5 having a threaded portion at an upper outer peripheral edge and at least one lower filter cylinder 6. The filter medium 7 such as activated carbon or sand is accommodated in the interior of.
At this time, a large number of raw water discharge holes 5 a and 6 a are formed in the bottom surfaces of the upper filter cylinder 5 and the lower filter cylinder 6.
Such a conventional cartridge moves the raw water through the raw water discharge holes 5a, 6a of the upper filter cylinder 5 and the at least one lower filter cylinder 6 so as to naturally fall downward, and the filter medium 7 of each filter cylinder. Filter through.

  However, since the conventional cartridge described above is filtered while the raw water naturally falls from the upper part to the lower part, the filtration time is short, the contact efficiency with the filter medium is poor, and the filtration efficiency is lowered overall. There was a problem.

  In particular, while the raw water naturally falls from the upper part to the lower part, the raw water passes through the filter medium along the same path every time or passes through the inner peripheral surface of the filter cylinder, so that the raw water is effectively purified by the filter medium. There is a problem that the purification efficiency is further lowered due to the problem of being supplied in a fall state.

  Of course, unlike the cartridge shown in FIG. 2, there is also proposed a technique of filtering raw water from the bottom to the top while moving the raw water from the bottom to the top. However, there is a problem that the filtration efficiency greatly improved as compared with the above-described conventional technique cannot be obtained.

  The present invention has been made to solve the above-mentioned various problems of the prior art, and the object thereof is to stack a large number of filter tubes with built-in filter media on the top and bottom. By forming a vertical raw water supply hole with a supply pipe at the center in the center, the raw water is guided and supplied to the lower part of the filter cylinder, and is filtered and discharged while moving from the lower part to the upper part. It is to provide a dexterous cartridge.

  In particular, the raw water moves up and down while being guided zigzag inside and outside by the guide protrusions on the inner peripheral edge of the filter cylinder, so the purpose is to further increase the filtration efficiency by increasing the filtration time and contact efficiency with the filter medium. To do.

  The present invention includes an upper filter cylinder provided with a hollow supply pipe at the center, a through hole at the bottom, and at least one guide protrusion for guiding the raw water to the inner center at the inner periphery, and at least one lower filter. The cylinders are separately formed and stacked and joined sequentially on the bottom filtration cylinder, but by forming a vertical raw water supply hole with the central supply pipe of the upper and lower filtration cylinders, the raw water is placed in the lower part of the filtration cylinder. It is characterized in that it is filtered and discharged while being supplied and moved upward.

  According to the present invention, the inner and outer portions of the upper filter tube, the lower filter tube, and the bottom filter tube are formed with correspondingly downwardly inclined surfaces on the inner and outer sides, and are adhesively bonded so that they are inserted and laminated with each other. There is a special feature.

  The present invention includes an upper filter cylinder provided with a hollow supply pipe at the center, a through hole at the bottom, and at least one guide protrusion for guiding the raw water to the inner center at the inner periphery, and at least one lower filter. Separately form the cylinders and stack and join them sequentially on the bottom filter cylinder, and assemble at least one inner cylinder that is inserted into the upper and lower filter cylinders in close contact with the inner peripheral surface of the filter cylinder However, the upper end of the inner cylinder protrudes inward to form a guide projection that guides the raw water to the inner center, and the upper and lower filter cylinders form a vertical raw water supply hole by the central supply pipe. Thus, the raw water is supplied to the lower part of the filter cylinder and is filtered and discharged while moving upward.

  The present invention as described above is configured by laminating a large number of filter cylinders with built-in filter media on top and bottom, and by providing a vertical raw water supply hole with a supply pipe at the center inside the filter cylinder, raw water is filtered. It is guided and supplied to the lower part of the tube and filtered and discharged while moving from the lower part to the upper part. There is an effect that the filtration efficiency can be further maximized by increasing the time and the contact efficiency with the filter medium.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

That is, the natural filtration type water purifier cartridge 100 of the present invention includes an upper filtration cylinder 10, at least one lower filtration cylinder 20, and a bottom filtration cylinder that incorporate various filter media 60 therein, as shown in FIGS. 3 to 6. 30 are sequentially stacked and joined, but in the center of the upper filtration cylinder 10 and the lower filtration cylinder 20, hollow supply pipes 12 and 22 are stacked and connected to each other to supply raw water to the bottom filtration cylinder 30. The raw water supply holes 40 are formed vertically, and a plurality of through holes 11 and 21 for ascending and guiding the raw water are provided at the bottoms of the upper filter cylinder 10 and the lower filter cylinder 20 so that the raw water moves from the lower part to the upper part. While being filtered.
Further, at least one guide protrusion 50 is provided on the inner peripheral edge of the upper filter cylinder 10 and the lower filter cylinder 20 so as to guide the raw water inward.
The filter medium 60 accommodated in the upper filter cylinder 10, the lower filter cylinder 20, and the bottom filter cylinder 30 stores activated carbon, sand, other materials, etc., but the same or different filters are used for each filter cylinder. You may comprise so that various filtration effects can be acquired by accommodating a material.
Further, an upper plate 15 having a number of discharge holes 15a is coupled to the upper portion of the upper filter cylinder 10 so that the filtered purified water overflows and is discharged.
The portions of the upper filter tube 10, the lower filter tube 20 and the bottom filter tube 30 that are in contact with the outside are laminated together with correspondingly formed downward inclined surfaces 61, 61 ', 62, 62' on the inside and outside. Adhesively bond as follows.
Reference numeral 210 as an unexplained symbol indicates a connecting pipe that connects the ceramic filter 200 and the supply hole of the cartridge 100.
Next, the operation and action of the present invention configured as described above will be described.
In the present invention, the upper filter cylinder 10, at least one lower filter cylinder 20 and the bottom filter cylinder 30, in which activated carbon, sand, or other material filter medium 60 is housed, are sequentially laminated and bonded by a method such as heat sealing. .
At this time, the filter tubes are laminated and bonded in a constant and firm manner by the downward inclined surfaces 61, 61 ′, 62, 62 ′ formed corresponding to the portions contacting the inside and the outside.
The cartridge 100 of the present invention assembled in this way is installed in a natural filtration type water purifier as shown in FIG. 1, but again filters the raw water supplied after being primarily filtered by the ceramic filter 200.
More specifically, the raw water primary-filtered by the ceramic filter 200 is dropped and supplied to the bottom filtration cylinder 30 at the lowest position through the raw water supply hole 40 at the center inside the cartridge 100.
The raw water supplied to the bottom filtration cylinder 30 in this way undergoes a filtration process while moving from the lower part to the upper part of the cartridge.
That is, the raw water ascends from the bottom filter cylinder 30 through the lower filter cylinder 20 and the upper filter cylinder 10 sequentially through the through holes 11 and 21 at the bottom of each filter cylinder.
During this process, the raw water undergoes a filtration process by the filter medium 60 in each filter cylinder 10, 20, 30.
In particular, the guide protrusions 50 provided on the inner peripheral edges of the upper filter cylinder 10 and the lower filter cylinder 20 prevent the raw water from moving upward along the inner wall surface of the filter cylinder as in the prior art. In addition to further extending the filtration time while being guided inwardly by 50 to move upward in a zigzag manner, the contact efficiency with the filter medium can be increased to further maximize the filtration efficiency.
The purified water filtered while moving from the lower part to the upper part of each filter cylinder 10, 20, 30 in this manner overflows and is discharged through a discharge hole 15 a provided in the upper plate 15 of the upper filter cylinder 10.
On the other hand, the present invention can be implemented differently as shown in FIGS. 7 and 8, but this is because the inside of the upper filter cylinder 10 and the lower filter cylinder 20 is compared with the preferred embodiment described above. Is constructed by assembling at least one inner cylinder 70 to be inserted in close contact with the inner peripheral surface of the filtration cylinder, but the upper end of the inner cylinder projects inward to guide the raw water to the inner center. A protrusion 75 is provided.
That is, in the embodiment of the present invention as described above, the guide projection provided integrally with the inner peripheral edge of the filter tube is provided in the separate inner tube and inserted into the filter tube in the embodiment of FIGS. Therefore, the effect by the above-mentioned guide protrusion is obtained while simply providing the manufacture of the filter tube.
The guide protrusion 75 of the inner cylinder 70 may be formed in a ring shape entirely on the inner peripheral edge, or may be partially formed although not shown.
Therefore, the present invention maximizes the filtration time by moving and guiding the raw water to the inside and outside by the guide projections of the filtration cylinder or the inner cylinder while moving the raw water from the lower part to the upper part in a number of filtration cylinders stacked vertically. The contact efficiency with the filter medium can be maximized to provide excellent water purification efficiency.
