MULTI-CARTRIDGE USED IN THE BACKWASHIN FIBER FILTER SYSTEM}

The present invention relates to a multi-cartridge used in a backwash fiber yarn filter system, and more particularly, a backwash fiber yarn capable of automatically backwashing when a filtration capacity reaches a limit while filtering particulate matter contained in a fluid. A multi-cartridge used in a filter system.

In general, the performance of a filtration device used for wastewater filtration treatment is determined by the removal efficiency of suspended solids, filtration rate, filtration duration, and the like. Inorganic particulate materials such as sand and anthracite are mainly used as the filter medium to be filled in the filtration device, and the filtration device formed of such a filter material has a space for trapping the suspended matter confined near the surface layer so that the filtration pressure increases rapidly when the pores are blocked. As a result, the filter replacement cycle is shortened.

In addition, a multi-cartridge filter made of a thermoplastic resin such as polypropylene and polyester is also widely used as a filter medium to be filled in the filtration device. However, since the filter medium must be disposed of after a certain period of time, another environmental pollution problem occurs, and the cake Due to the (cake) phenomenon, it is necessary to replace the filter media, expensive facility costs, and even if the backwashing process is very difficult to implement, the backwashing efficiency is very low.

In recent years, a filtration apparatus using a fiber yarn capable of improving the performance of the filtration apparatus and allowing backwashing is being developed.

The filtration device having a variable filter layer devised by Choi, Choong-Hyun and disclosed in Korean Patent Publication No. 10-0241198 fixes fiber fibers at the bottom of the filter to squeeze the filter material with raw water supply pressure and expand the filter material with air and washing water supply pressure. It is related to the filtration device. Since the filtration layer is monolayer and the degree of squeezing of the filter medium is determined by the raw water supply pressure, the trapping space of the suspended substances is small, so that the filtration duration is short, the frequency of washing is frequent, and it is easy to cope with the fluctuations in the water quality It has a problem that it is difficult to arbitrarily control the desired water quality and quantity.

In addition, the permanent filtration device devised by Choi, Choong-hyun, and disclosed in the Republic of Korea Patent Publication No. 1999-030247 discloses a top-down filtration method, which can also completely remove the waste liquid from the filtration device during the daily washing process. It takes a lot of washing water, and relaxes and compresses the filter media in the vertical direction by the piston, so if you use it for a long time, there is a risk of damage to the filter media. There is a problem.

The present invention has been made to solve the above problems, and it is possible to filter the particulate matter contained in the fluid and at the same time the multi-cartridge filter system used in the backwash fiber yarn filter system that can automatically backwash when the filtration capacity reaches the limit. The purpose is to provide.

Hereinafter, the operating principle of an embodiment of the present invention will be described in detail.

When the filtration is to be performed using the multi-cartridge 100, the opening / closing valve 14a of the circulating water supply pipe 14 and the opening / closing valve 21a of the circulating water discharge pipe 21 are opened, and the driving bar 110 is lowered. Move to. When the driving bar 110 moves downward, the disk plate 121 together with the driving bar 110 also moves downward. At this time, the upper protrusion 111 of the drive bar 110 formed on the upper side of the disk plate 121 pushes the disk plate 121 downward to make the sliding movement downward with respect to the driving bar 110. As the disc 110 moves downward, the disc plate 121 moves downward until the disc plate 121 engages with the lower protrusion 133 of the case 131. Therefore, as shown in FIG. 4, each disc plate 121 is sandwiched between the upper protrusion 111 of the driving bar 110 and the lower protrusion 133 of the case 131, and the disc plate 121. The distance between them is farther apart. As the distance between the disk plates 121 increases, the fiber yarns fitted to the rubber rings 122 expand and become in tension, and the pore sizes become d1 and d2. In this state, when the circulating water is supplied through the circulating water supply pipe 14, foreign matter is filtered by the pores of the fine fiber yarn 140.

Similarly, when the fiber cartridge 140 is to be cleaned using the multi-cartridge 100, the on / off valve 26a of the backwash water supply pipe 26 and the on / off valve 99a of the backwash water discharge pipe 99 and compressed air The opening / closing valve 32a of the supply pipe 32 is opened, and the drive bar 110 is moved upward. When the driving bar 110 moves upward, the disk plate 121 together with the driving bar 110 also moves upward. At this time, the lower protrusion 112 of the driving bar 110 formed below the disk plate 121 pushes the disk plate 121 upward to make the sliding movement upward with respect to the driving bar 110. As the disc 110 moves upward, the disc plate 121 moves upward until the disc plate 121 engages with the upper protrusion 132 of the case 131. Accordingly, as shown in FIG. 3, each disc plate 121 is sandwiched between the lower protrusion 112 of the driving bar 110 and the upper protrusion 132 of the case 131, and the disc plate 121. The gap between them gets closer. As the spacing between the disk plates 121 approaches, the fiber yarns fitted to the rubber rings 122 are relaxed, and the pores are sparsely sized, such as d1 'and d2'. In this state, when the filtered water is supplied with compressed air through the backwash water supply pipe 26, foreign substances caught in the pores of the fiber yarn 140 are separated from the fiber yarn 140 and accumulated at the bottom of the multi-cartridge 100. It is possible to remove the foreign matter stuck to the fiber yarn 140.
