<p>The present invention relates to a filtering device for a wet sand screening apparatus. When mixed water mixed with sand produced by the wet sand screening apparatus and powder passes through dividing partition walls, which are boundaries for first, second, third, and fourth precipitation division units, the sand and powder in the mixed water collided with the dividing partition walls to be dropped downward from the first, second, third, and fourth precipitation division units and be accumulated. Then, the filtered water from which the sand and powder are removed is easily discharged, separation of the sand, powder, and filtered water becomes effective, and the filtering process for the wet sand screening apparatus is expedited and facilitated for the production of high-quality sand. The filtering device (10) is provided with a main body (10a) that is open upward and has a space portion (11) therein, a discharge unit (12) being formed below the space portion (11) so that sand and powder are discharged, the cross-shaped dividing partition walls (13) are disposed in the space portion (11) for the formation of the first, second, third, and fourth precipitation division units (13a, 13b, 13c, 13d), the mixed water in which the sand and powder are mixed with each other flows to one side of the first precipitation division unit (13a), the sand and powder collide with the dividing partition walls (13) when the mixed water that flows in passes through the first precipitation division unit (13a) to the fourth precipitation division unit (13d), the sand and powder being dropped downward from the first, second, and third precipitation division units (13a, 13b, 13c, 13d) and being accumulated in this case, and the filtered water from which the sand and powder are removed is discharged to one side of the fourth precipitation division unit (13d).</p> |
