BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for separating a liquid mixture, and more particularly, to an apparatus for separating a liquid mixture capable of inductively separating sludge (solid particles) mixed in a liquid mixture and separating almost even the liquid impregnated in the sludge.

In general, there are several methods for separating solid particles and the like mixed in a liquid such as water.

Conventional precipitation or heat evaporation methods are not only able to separate a large amount of liquid mixture, but also require too much time to separate the liquid mixture, and thus are used only in special cases such as salt farms and laboratories.

In addition, there is a high pressure separation method for separating pure liquid and solid particles from a liquid mixture using a high pressure. However, this method has a disadvantage in that even if a high pressure is applied to the liquid mixture, there is a limit in separating the liquid impregnated into the solid particles, so that a high dehydration rate cannot be obtained.

In addition, there is a high pressure filtration method to filter and dewater by using a high pressure, but this method forms a concentrated membrane of the filtered material on the surface of the filter medium over time, this concentrated membrane prevents the liquid mixture from passing through the micropores of the filter medium Since the dehydration efficiency decreases over time or maintains the same level of dehydration efficiency, a higher dehydration pressure was required.

Accordingly, an object of the present invention is to provide a separation device of a liquid mixture which can obtain a high dehydration efficiency without using a high pressure as an improvement of the above disadvantage.

In order to achieve the above object, by applying a constant amount of electricity to the liquid mixture including the sludge, the pure liquid is moved in the negative electrode direction while the sludge is moved in the positive electrode direction. Thus, the sludge and the pure liquid are configured to separate high efficiency. In this case, the sludge means small solid particles mixed in a liquid or solid agglomerates which are agglomerated with each other, and the liquid mixture refers to a liquid mixture in which the sludge is mixed in a liquid.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows the principle of separating sludge from a liquid mixture.

FIG. 1 (a) shows a liquid mixture 3 containing sludge 2 in the container 1 and a positive distance between the positive electrode 4 and the negative electrode at a predetermined distance inside the container 1. -) The state in which the electrode 5 is dipped is shown. FIG. 1 (b) shows a state in which a DC electric current of 25 to 220 V and 0.1 to 10 A is applied to the positive electrode 4 and the negative electrode 5 described above. The sludge 2 moves to the electrode 4, while the pure liquid 3 ′ moves to the negative electrode 5.

At this time, the movement of the sludge 2 to the positive electrode 4 having a positive electrode is a phenomenon of electric induction, and the pure liquid 3 'moves to the negative electrode 5 having a negative electrode. Is the phenomenon of electrical penetration.

2 shows the first embodiment of the present invention and shows the configuration of the roller dehydration machine.

This is to install a plurality of upper rollers (10) for supplying positive electricity and a plurality of lower rollers (11) for supplying negative electricity, respectively, facing up and down, so that the inlet is wider and the outlet is narrower. It is made up.

Therefore, the liquid mixture 12 mixed with the sludge 13 is pushed into the inlet and rotated in the advancing direction while supplying positive and negative electricity to the upper roller 10 and the lower roller 11, respectively. This causes the liquid mixture 12 to move towards the outlet. At this time, the pure liquid 12 'to the lower roller 11 to which the negative (1) electricity is supplied falls down through the space 11a between the lower rollers 11 while moving by the principle of electroinfiltration. The sludge 13 is moved toward the upper roller 10 to which positive electricity is supplied, and moves in the exit direction. Thus, while the liquid mixture 12 moves in the outlet direction, the liquid 12 'is removed from the liquid mixture 12, and the sludge 13 solidifies into a hard solid 13a and exits the outlet.

Figure 3 shows a second embodiment of the present invention, showing the configuration of a screw press dewatering machine.

A plurality of screw blades 15a are formed on the rotating shaft 15 which is rotated by the drive motor 14 and supplied with positive electricity, and moves in the other direction, and negative (-) outside the rotating shaft 15. The case 16 is provided with a gap 16a through which electricity is supplied and the liquid can escape, and the liquid mixture 17 containing the sludge 18 is supplied to the inlet 16b.

Therefore, while driving the drive motor 14 while inserting the liquid mixture 17 containing the sludge 18 into the inlet 16b, the rotating shaft 15 and the screw blades 15a rotate, while the rotating shaft 15 When positive and negative electricity are respectively supplied to the case 16, the liquid mixture 17 containing the sludge 18 is moved to the outlet 16c by the screw vanes 15a, At this time, the sludge 18 is collected in the direction of the rotation axis 15 by the electric induction by positive (+) electricity and moves in the direction of the outlet 16c by the screw vanes 15a, while the negative By the electrical penetration, the pure liquid 17 'moves out of the case 16a while moving in the case 16 direction. Therefore, while the liquid mixture 17 enters the inlet 16b and moves in the direction of the outlet 16c by the rotating shaft 15 and the screw vanes 15a, the liquid 17 'is removed and the sludge ( 18 hardens into a solid solid 18a and exits to outlet 16c.

4 shows the third embodiment of the present invention and shows the configuration of a belt press dewatering machine.

The upper belt conveyor 19, which is moved by the upper rotary rollers 19a, 19b, and the lower belt conveyor 20, which is moved by the lower rotary rollers 20a, 20b, are installed. Inside the 20, a positive electrode 21 supplied with positive electricity and a negative electrode 22 supplied with negative electricity are housed, and the upper belt conveyor 19 has a half. The lower belt conveyor 19 which rotates clockwise and the gap 20c is rotated clockwise, respectively, is configured to push the liquid mixture 23 containing the sludge 24 into the inlet. At this time, the belt conveyor (19, 20) is preferably formed in an orbit and formed of a conductive material.

Therefore, the upper and lower belt conveyors 19 and 20 are rotated while the liquid mixture 23 containing the sludge 24 is pushed into the inlet, and at the same time, the positive electrode and the positive electrode are connected to the two electrode rods 21 and 22. When negative electricity is supplied, the liquid mixture 23 moves to the outlet according to the rotation of the two belt conveyors 19 and 20, and during the movement, the sludge ( 24 moves while being pulled toward the upper belt conveyor 19, while the pure liquid 23 'is forced downward through the gap 20c formed in the lower belt conveyor 20. Thus, the liquid 23 'is removed from the outlet, and the sludge 24 solidifies into a solid solid 24a and exits the outlet.

Figure 5 shows the fourth embodiment of the present invention, showing the state used for the sedimentation sedimentation of the waste water treatment plant.
