In the empty interior space of the main body 200, pie-shaped cartridges 222 filled with activated carbon 230 of a predetermined capacity are housed.

The cartridges 222 have a rounded front portion and pie slices formed on both side portions of the front portion with inclined surfaces, and each side portion of these cartridges 222 is connected to each other to form a cylindrical cassette module 220. It is installed in the empty interior space of the main body 200.

Here, meshes 226 and 228 in a mesh form are installed on the upper and lower surfaces of the cartridges 222 so that only water passes and the activated carbon 230 filled therein does not escape.

Handles 224 are formed on the rounded front portions of the cartridges 222, which will be described later.

On the other hand, the side portion of the main body 200 is provided with an opening and closing door 204, the raw water flowing through the raw water inlet 202 around the upper side of the guide only to the cylindrical cassette module 220 of the cartridges 222 Guide portion 214 is formed to be.

Referring to the operational relationship of the filter for the cassette-type activated carbon filter having the configuration as described above are as follows.

First, as shown in FIG. 5 and FIG. 6, there are provided piezo-shaped cartridges 222 manufactured at the factory with a certain amount of activated carbon filled therein, and these cartridges 222 are connected to each side portion. After the cylindrical cassette module 220 is made, it is introduced into the body portion 200.

That is, the cylindrical cassette module 220 is introduced in the lateral direction through the opening formed in the opening and closing door 204 formed on the side of the main body 200. In this case, as described above, the plurality of cartridges 222 may be made into a cylindrical cassette module 220 and introduced at a time. The cartridges of the cylindrical cassette module may be inserted into the main body 200 by sequentially inserting the cartridges 222 one by one. 220 may be formed.

Therefore, the plurality of cartridges 222 are embedded in the inner space of the main body 200 as shown in FIG. 7 while forming the cylindrical cassette module 220.

In this state, when the raw water to be purified through the raw water inlet 202 of the main body 200, the raw water is cartridge 222 by the guide of the guide 214 formed around the upper side of the main body 200 It is drawn into the cartridge 222 through the mesh-shaped mesh 226 formed on the upper surface of the field.

As such, the raw water introduced into the cartridges 222 passes through the activated carbon 230 filled in the cartridge, whereby various contaminants and impurities included in the raw water are adsorbed by the activated carbon and formed only on the purified water. The mesh is dropped downward through the mesh 228.

The purified water passing through the mesh mesh 228 formed on the lower surface of the cartridge 222 passes through the water hole 216a of the pedestal 216 to form a drainage space 218 forming a predetermined space of the main body 200. Through the discharge to the purified water outlet 210 is made.

Activated carbon filled in the cartridges 222 are continuously placed inside the cartridge without being separated out of the cartridge by mesh meshes 226 and 228 installed on the upper and lower surfaces, respectively.

For reference, reference numeral 212 in the drawing is a mesh-shaped mesh installed between the tip of the purified water outlet 210 and the drainage space 218 of the main body 200, or if the lower surface of the cartridge 222 mesh (228) When some of the activated carbon exits the drainage space 218 through the water supply hole 216a of the pedestal 216 and the pedestal 216, the activated carbon is not discharged through the purified water outlet 210.

If the adsorption performance of the activated carbon filled in the cartridge 222 is deteriorated because the filtration process for purifying the raw water is performed for a long time as described above, the operation of the filtration facility is stopped for a while and the opening and closing door 204 of the main body 200 is opened. Some cartridges can be removed laterally through the openings and replaced.

That is, the handle 224 is formed on the rounded front portion of the cartridge 222, and the handle 224 is pulled out laterally by holding the handle 224, and then a new cartridge may be introduced.

As such, the cartridges 222 constituting the cylindrical cassette module 220 are each provided as objects, and thus, only a part of the cartridges may be replaced without replacing the entire cartridge at the same time, thereby shortening the replacement period as well as the replacement. The work is also very easy.

For reference, in the exemplary embodiment of the present invention, the opening and closing door 204 is installed at the side of the main body 200, and the handle 224 is formed at the front of the cartridge 222 so that the cartridge 222 is moved laterally. Although it was described as replacing while receiving, it is possible to form a cover that can be opened and closed on the upper surface of the main body portion 200 as in the prior art, by forming a handle on the upper surface of the cartridge can be replaced according to the lifting from the top.

On the other hand, the filtration process of the filter for the cassette-type activated carbon filter according to the present invention is as follows. First, as shown in Figure 8a, the cartridge of the cassette-type activated carbon filter for the filter configured as described above filled the activated carbon 230 by 50 to 70% of the total volume, and after it is introduced into the main body 200, Perform filtration.

Here, the raw water introduced through the raw water inlet 202 of the main body 200 is filtered through the activated carbon 230 in the cartridges 222 constituting the cassette module 220, and the purified water is discharged through the purified water outlet. Since the process is described above, the repeated description will be omitted.

As a result of filtration, when impurities are adsorbed on the activated carbon filled in the cartridges 222 and the adsorption performance is lowered, as shown in FIG. 8B, a backwash process is performed.

That is, when backwashing is performed, the operation of the entire filtration facility is temporarily suspended, and the backwashing water is supplied through the purified water outlet 210 of the main body 200.

Accordingly, the backwash water passes through the water hole 216a of the pedestal 216 and the lower surface mesh 228 of the cartridges 222 through the drainage space 218 and is activated carbon, which is a layer of media filled in the cartridges 222. Inflate 230.

In this case, as described above, the activated carbon 230 is filled by only 50 to 70% of the total volume in the cartridge 222, and expands according to the supply of backwash water, so that the impurities such as impurities soar upward.

In this state, when the supply of the backwash water is stopped for a certain time, the activated carbon serving as the filter bed sinks downward, and debris such as impurities accumulate thereon, and when these wastes are discharged to the outside, the backwashing is completed.

Therefore, the backwashing process thus improves the adsorption performance of the activated carbon 230 in the cartridge 222, which can be further used for filtration of raw water without replacing it, thereby increasing its service life and eventually increasing its efficiency. do.
