On the other hand, the present invention shows an embodiment of a filter unit 40, which is excellent in air purification efficiency and is easy to clean and easy to maintain and manage, as illustrated in FIG. 6.

The filter unit 40 of the present embodiment is mounted to rotate and interlock with a lower partition plate 41 in which a plurality of flow holes 411 are formed at the edge portion, and the lower partition plate 41 is spaced apart from each other, and a plurality of perforations A chamber in which the upper partition plate 43 having 431 formed thereon and the upper partition plate 43 are integrally rotated and connected to the air discharge line 441 and the backwash water inlet line 442 at the upper end by a valve (44) and the elastic line member 421 is stacked in a spiral manner and a hollow is formed therein. In the lower partition plate 41 to the upper partition plate 43, each of the perforations 431 It characterized in that it comprises a plurality of spiral pipes 42 connected so as to communicate with the hollow.

The lower partition plate 41 has a plurality of flow holes 411 formed at the rim while partitioning the inner space 100 of the post 10 so that the air introduced into the inner space 100 is transferred into the filter unit 40. It is to be introduced through the flow hole 411.

As the air introduced in this way passes through the plurality of spiral pipes 42, the air from which foreign substances are filtered flows upward in the inner space 100 through the air discharge line 441.

In particular, the upper partition plate 43 and the chamber 44 are mounted so as to be rotatable in the inner space 100 of the post 10.

The reason why the upper partition plate 43 and the chamber part 44 are mounted to enable rotational interlocking in the inner space 100 is that when a blockage occurs in the filtration process of the spiral tube 42, the spiral tube 42 This is to prevent deformation and destruction of the spiral tube 42 by making the upper partition plate 43 as a free end as one end of the spiral tube 42 in the case of deposition of foreign matter between them.

For example, when foreign substances are deposited between the spiral pipes 42, the foreign substances are automatically separated by the rotation of the upper partition plate 43 and the chamber 44, and the upper partition plate 43 is removed by the restoring force of the spiral pipe 42. ) And the chamber portion 44 to be restored to its original position to prevent deformation and destruction of the spiral pipe 42 as mentioned above.

The structure in which the upper partition plate 43 and the chamber part 44 are mounted to enable rotational interlocking in the inner space 100 can be implemented by various known techniques such as ball bearings, so a detailed description thereof will be omitted.

The upper partition plate 43 has a plurality of perforated holes 431 as shown in FIG. 8, and the spiral pipe 42 is fixed to the upper partition plate 43 so that the hollow communicates with the perforated holes 431. It is fixed. By this configuration, the filtered air is stored in the chamber 44 by going upward through the hollow of the spiral pipe 42 and discharged to the internal space 100 through the air discharge line 441.

The spiral tube 42 has a shape in which a hollow is formed inside while the elastic line members 421 are spirally stacked, and each perforation 431 in the lower partition plate 41 and the upper partition plate 43 ) Corresponds to a configuration in which the hollow is connected to communicate with each other.

The spiral pipe 42 is a structure in which elastic line members 421 are stacked in a spiral manner, and naturally has an elastic restoring force as it has a structure such as a spring. With this structure, the air introduced into the flow hole 411 passes between the pitches of each line member 42 so that foreign matter is filtered out, and the air filtered out of the foreign matter moves upward through the hollow.

As mentioned above, when the elastic restoring force of the spiral pipe 42 and the rotational interlocking of the upper partition plate 43 and the chamber 44 are organically interlocked, when non-uniform pressure such as deposition of foreign substances is formed, It is to make it possible to recover to the original state by allowing tally etc. to occur.

In particular, in this embodiment, when the cleaning process is performed, the backwash water inlet line ( It is characterized in that the operation is performed by opening 442).

That is, as shown in FIG. 9, the upper partition plate 43 and the chamber 44 rotate, and according to this rotation, the spiral pipe 42 is elongated. Due to the extension of the spiral tube 42, the pitch (P) spacing between the line members 421 forming the spiral tube 42 increases, and foreign matter (S) deposited between the line members 421 by backwashing water flowing through the hollow It is detached from this spiral pipe 42.

In the backwashing process, the rotational connection between the upper partition plate 43 and the chamber 44 is not shown in the drawing when the backwash water inlet line 442 is operated, but the upper partition plate 43 is driven by a driving means. And the chamber 44 is rotated. The operation mechanism for rotating the upper partition plate 43 and the chamber 44 by the driving means can be implemented by various known techniques, and thus a detailed description thereof will be omitted.

It will be appreciated by those skilled in the art through the above description that various changes and modifications can be made without departing from the technical idea of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be determined by the claims.
