Since the solid-liquid separation module 100 shown in FIGS. 4 to 7 differs only in the shape of the first filter 120, the first filter 120 will be mainly described herein.

The first filter 120 of this embodiment is also mounted on the filter mounting portion 111 and surrounds the hole 113 formed in the side wall 112 and is provided in the inside of the tubular filter mounting member 110, It is for filtering contaminants. The first filter 120 of this embodiment also has a hollow cylindrical shape, but unlike the previous embodiment, the first filter 120 has a protruding resistance portion 121 protruding outward. The protruding resistance portion 121 can receive a large amount of resistive force of the water that is locked by the tubular filter mounting member 110 when the tubular filter mounting member 110 rotates so that the contaminant blocking the first filter 120 is absorbed by the first filter 120, So that it can be easily separated from the substrate. The protruding resistance portions 121 are formed in the vertical direction, and a plurality of the protruding resistance portions 121 are disposed adjacent to each other along the circumference of the first filter 120. Preferably, the protruding resistance portion 121 is formed along the entire circumference of the first filter 120. Needless to say, the protruding resistance portions 121 may be formed at intervals along the circumference of the first filter 120.

The protruding resistance portion 121 in this embodiment has a mountain-shaped cross-sectional shape. The protruding resistance portion 121 forms wrinkles along the periphery of the first filter 120.

In this embodiment, the filtering material of the first filter 120 may have a single or a composite configuration. Composite construction may be physical materials with different shapes such as sponge, iron, semi-gravel, sand, etc., or materials or media capable of chemical / catalytic reaction. When the filtering material is hard, it can be formed by itself. In the case where the filter material is not rigid, the first filter 120 has a filter housing in which holes for allowing water to pass between the inside and the outside are opened, Surface.

The cross-sectional shape of the protruding resistance portion 121 may have a single cross-sectional shape or a pattern in which a plurality of cross-sectional shapes are successively repeated or interspersed or repeated.

The overall shape of the first filter 120 may be a hollow cylindrical shape, a truncated conical shape or a truncated polygonal pyramid shape and may be formed of a cylindrical filter mounting member 110 ), Vibration or impact by means of a high-frequency, ultrasonic wave or the like can be used to separate foreign matter adhering to the filter.

The filter cleaning process of the solid-liquid separator according to the present invention will be described with reference to the drawings.

In this embodiment as well, the solid-liquid separation module 100 filters the contaminants contained in the contaminated water flowing from the outside of the cylindrical filter mounting member 110 into the first filter 120.

The contaminated water flows into the tubular filter mounting member 110 through the hole 113 through the first filter 120 and becomes purified water. The purified water in the tubular filter mounting member 110 is discharged to the outside through the drainage part 131 formed on the side surface of the rotation support part 130 via the opening part 115 above the filter mounting part 111.

If the first filter 120 is blocked by long-term filtration, if the motor 142 is driven to rotate the rotary shaft 141 in one direction, the cylindrical filter mounting member 110 is also rotated, And rotates together with the cylindrical filter mounting member 110. Accordingly, the contaminants that have blocked the first filter 120 are separated from the first filter 120 by the pressure of the water. In particular, the protruding resistance portion 121 protruding outwardly can receive a large resistance force of the water immersed by itself when the cylindrical filter mounting member 110 rotates, so that the contaminant blocking the first filter 120 So that the first filter 120 can be easily detached from the first filter 120.

The fine holes formed in the general cylindrical filter without the protruding resistance portion 121 are radially directed so that even if the filter rotates, it does not receive a large pressure of water. However, the protrusion protruded outward as in the first filter 120 of the present invention Since the fine holes formed in the resistance portion 121 are closer to the tangential direction tangent to the circumference of the circle of the circle itself rotating than the fine holes formed in the cylindrical filter without the protruding resistance portion 121, It receives a great pressure when rotating. Accordingly, the pollutant that has clogged the first filter 120 is easily separated from the first filter 120, so that the filter cleaning effect is excellent.

According to the present invention, the surface area of the first filter 120 is large, and a large amount of water can be passed per unit time.

The grooves 117 or protrusions are formed on the outer circumferential surface of the filter mounting portion 111 of the tubular filter mounting member 110 in the up and down direction so that the valleys 122 between the protruding resistance portions 121 of the first filter 120, It is possible to make the inner side of the inner tube 20 hang. It is possible to fix the first filter 120 by pressing the upper flange 132 and the lower flange 133 as described above but it is also possible to form the groove 117 or the protrusion in the vertical direction on the outer peripheral surface of the filter mounting portion 111, The inner side of the valley 122 between the protruding resistance portions 121 of the filter 120 can be caught so that the first filter 120 can be installed more firmly on the outer surface of the cylindrical filter mounting member 110.

The rest is the same as described with reference to Figs.

The first filter 120 may include a filtering material 125 for filtering contaminants and a filter housing 124 for receiving and protecting the filtering material 125 therein. The filter housing 124 surrounds the outer surface and the inner surface of the filtering material 125 and has holes 124a formed through which water can pass between the inside and the outside.

As the filtering material 125, a physical material having different shapes such as a sponge, a semipermeable, a gravel, a sand, or a material or a filter material capable of chemical / catalytic reaction may be used. If the filtering material is rigid, it can be molded on its own, and if it is not a rigid material, the filter can have a filter housing on its surface to allow for water to pass between the inside and the outside and to accommodate the filter material therein . The filter housing may be made of a metal such as iron or stainless steel, a polymer such as nylon or polyethylene, a composite material, or other materials.

Various materials may be used alone or in combination. In this case, not only the inner filtering material 125, but also the filter housing on the filter surface has protruding resistance portions 121 protruding outward. The filter housing 124 may be made of a metal such as iron or stainless steel, a polymer such as nylon or polyethylene, a composite material, or other materials.
