It largely consists of a first unit U1 including a housing 10 , a guide means 20 , and a water supply line 30 .

Looking at each configuration,

The housing 10 is

As shown in Figures 1 to 4,

It consists of an enclosure structure having an inner space (11).

At this time, the space 11 has a circular shape when viewed from the top and has a structure having the same cross-sectional space up and down. It forms one space together with the extended space part 12 having a space.

As a result, in the space 11, the supplied water and purified water are mixed, and in the extended space 12, foreign substances with a large specific gravity included in the water (eg, blasting raw materials such as sand, and the workpiece). separated debris, etc.) is precipitated and collected.

In addition, as shown in FIG. 1 , the housing 10 is further provided with a drain hole 13 disposed at the center of the bottom of the extension space 12 . A separate pipe is connected to the drain hole 13 and can be drained to the outside or supplied to an external purification device, and the water purified by the external purification device is supplied back to the water supply line 30. A selective circulation cycle process This can be done. For this selective circulation cycle process, an on/off valve and a pump (eg, a diaphragm pump) that are disposed on a separate pipe body connected to the drain hole 13 and operated by external control should be provided.

And as in FIGS. 1 and 2 , the housing 10 is fixedly supported spaced apart from the ground by a base 1 in which a plurality of transverse and longitudinal frames are interconnected and built on the ground.

The guide means 20 is

As shown in Figures 3 and 4,

To divide the space 11 of the housing 10 into an area A1 where water is stagnant and an area A2 where water is mixed,

By dividing the space 11 of the housing 10 into the stagnant area A1 and the mixing area A2, the water supplied from the outlet of the water supply line 30 is confined in the form of confinement. a guider (21) for slowing the flow rate to increase settling time, and

Distribution space (22) formed between the guider (21) and the outlet of the water supply line (30)

is made including

Here, the stagnant area A1 is an area in which water in a state with little flow stays, and foreign substances with a large specific gravity included in the water sink and settle toward the bottom of the extension space 12 of the housing 10 .

And in the mixing zone A2, a calm flow is formed by the water supplied from the outlet of the water supply line 30, and by this flow, mixing between the supplied water is made in the mixing zone A2 by this flow, especially The supplied water has a spiral structure of the water supply line 30 and a circular structure inside the space 11 of the housing 10, and a vortex is formed by the shape of the guider 21. Mixing is done slowly.

The concave-convex portion 213 or the embossed portion 214 collides with the water supplied from the outlet of the water supply line 30 to help disperse the flow of water.

In addition, as shown in FIG. 10 , the guider 21 extends from the end of the second guide plate 212 and extends in the curved direction of the second guide plate 212 and the first guide plate 211 . An arc-shaped skirt 215 that is bent to the side is further formed, so that when the water is guided along the inner wall of the second guide plate 212 and flows, the water meets the skirt 215 and the direction of the flow is changed once again. This helps to increase the mixing time between water and water.
