SIMPLE FILTERING DEVICE FOR DISCHARGING THE WATER FILM USED IN THE WATER FILM GROWN BY SIMPLE FILTRATION

摘要

The present invention relates to a simple filtering device for simply filtering and discharging water curtain water used in water curtain cultivation, which simply filters and discharges water curtain water used in a water curtain cultivation facility. Specifically, the simple filtering device comprises: a filtering chamber which is installed under the ground while being adjacent the water curtain cultivation facility to receive water curtain water, and to provide a filtering space for the water curtain water in a length direction, and includes an outlet from which the filtered water curtain water is discharged; a first filtration part which is provided in a part of the filtering chamber to provide a movement route for the water curtain water in the above ground part of the filtering chamber, and to filter foreign materials contained in the water curtain water; and a second filtration part which is provided in the rest of the filtering chamber to filter foreign materials contained in the water curtain water by flowing the water curtain water filtered in the first filtration part into the underground part of the filtering chamber, and by moving the same to the outlet. Accordingly, the simple filtering device can prevent the water curtain water used in water curtain cultivation from getting lost to the outside by filtering the same through the filtering chamber and the first and second filtration parts, and since the simple filtering device can store the water curtain water, the problems related to environmental pollutions, ground subsidence, etc. can be prevented in advance.
