When installing the filter portion, the cover portion is opened and the filter portion is inserted into the main body and coupled. When the filtration performance of the filter portion deteriorates, the filter portion is separated from the main body by the support member and withdrawn to the outside, and the filter material is replaced.

Description

Multifunctional Particulate Filter The present invention relates to a particulate filter, and more specifically, to a multifunctional particulate filter that facilitates the injection and replacement of filter media, enables air washing to effectively clean contaminants, and improves filtration performance. Generally, a filter is a device used in homes or industrial sites to filter out suspended solids and provide clean water by allowing water containing various suspended solids to pass through a container filled with a filter or adsorbent. To this end, various filters have been developed and provided, and in particular, as shown in FIGS. 1 and 2, a sand filter (10) is also called a multi-layer filter or a tank filter, in which various filter materials (12), such as activated carbon, anthracite, sand, and gravel, are stacked in layers inside a tank (11), and water flowing in through the inlet (13) passes through the filter materials sequentially, filtering out foreign substances, and then is discharged through the outlet (14). However, in a conventional sand filter (10), even if the filter material is filled to a thick thickness inside the tank (11), filtration occurs only on the upper surface of the filter material (12), so it has a filtration area only as large as the surface of the filter material (12). Therefore, as foreign matter gradually accumulates on the surface of the filter material (12), the filtration performance drops rapidly. Of course, when the filtration performance is reduced, as shown in FIG. 2, the direction of the water is reversed and the water is supplied through the discharge port (14) to remove foreign substances from the upper surface of the filter material (12), wash it, discharge it, and then proceed with the filtration process again. However, if the amount of foreign substances accumulated on the surface of the filter material (12) increases, the filtration performance is no longer restored even after washing. Therefore, after about 6 months to 1 year, the filter material must be replaced in part or in whole. Conventionally, however, the filter material (12) inside the filter (10) must be discharged through the discharge port (14), which takes a long time and is inconvenient. Likewise, the work of filling the filter material is also inconvenient and time-consuming, resulting in an economic burden due to the cost of replacing the filter material. In addition, recently, a technology has been proposed to supply air along with washing water by installing an air injection device at the bottom of the tank (11), but there was a problem in that the filtration performance was reduced as the different types of filter materials (12) stacked in layers were mixed together by the high-pressure air. Therefore, in conventional sand filters, air cannot be used during cleaning, and as the cleaning effect is reduced, frequent cleaning with water is required, which leads to a problem of increased water usage.
