Filtering apparatus employing multistage rotor generating variable vortex flow

Abstract

The present invention relates to a filtering apparatus for filtering raw water containing various impurities and mixtures into purified water, and more particularly to a multistage filtering apparatus in which a rotor for generating vortex are installed in each of multiple layers of filtration membrane stacked within a closed barrel and the rotors are formed in multistage by having different diameter of each rotor so that the power for generating vortex can be remarkably minimized by generating the vertical vortex from top and bottom of the rotary rotor and the horizontal vortex from the outer side of circumference plate of the rotary rotor to be crossed over between membranes to prevent from blocking the pores or remove the deposited pollutants, and the closed-type barrel having multistage of membranes, rotary shaft, and rotary rotors for vortex generation within are constructed as a single module of filter pack, and the filter pack is connected and extended in accordance with required purified capacity so that large scale installation of filtering apparatus is possible.

Description

technical field [0001] The present invention relates to a filter device capable of filtering fluid containing various impurities or mixtures (hereinafter referred to as raw water) into purified fluid (hereinafter referred to as purified water), in particular to a stepped filter device, which is installed in a closed Rotating pieces of different diameters used to generate vortex are arranged in steps between the multi-layer filter membranes in the barrel, so as to minimize the use of power. Background technique [0002] The function of the filter device is to filter the raw water polluted by impurities or mixtures, or containing mixtures into purified water. A generally used filter device is provided with a filter (hereinafter referred to as a membrane) having many micropores (Pore) called a thin separation membrane. [0003] When the raw water containing various pollutants is injected into the filter device, the sewage is filtered through the membrane installed in the filte...

Problems solved by technology

[0014] The purpose of the present invention is to solve the above-mentioned deficiencies, and provide a method to change the existing vertical filter device into a horizontal filter device, use a filter assembly of a certain size as a module, and connect multiple filters according to the purification capacity of raw water. According to the degree of pollution of the raw water, vortex generating rotating pieces of different sizes are set to meet the needs of users, save the rotating driving force of the rotating pieces, and then realize the enlargement of the filtering device, greatly improving Operational efficiency, at the same time, change the shape of the rotating disc so that it can generate vertical vortex and horizontal vortex at the same time, in order to reduce the power of the filtering device using the stepped variable vortex to generate the rotating disc
