HYDROPONICS CULTIVATION DEVICE

摘要

The present invention discloses a hydroponic cultivation apparatus. According to an embodiment of the present invention, the hydroponic cultivation apparatus includes: a nutrient mixing unit mixing the nutrient concentrate and raw water to form a nutrient solution; a nutrient solution tank storing the nutrient solution prepared in the nutrient mixing unit; a cultivation bed growing plants; and a nutrient solution supply unit which receives the nutrient solution from the nutrient solution tank to supply the nutrient solution to the cultivation bed. The nutrient solution supply unit includes: a nutrient solution storing unit arranged to store the received nutrient solution; and an absorption core supplying the nutrient solution in the nutrient solution storing unit to the floor of the cultivation bed by the capillary phenomenon. The nutrient solution in the nutrient solution tank is supplied to the nutrient solution storing unit due to the pressure difference. The nutrient mixing unit includes: a raw water supply pipe which is arranged to supply the raw water from an external water supply source to the nutrient solution tank while having a venture unit on the middle; a nutrient concentrate tank storing the nutrient concentrate; and a connection path connecting the venture unit and the nutrient concentrate tank to mix the raw water and the nutrient concentrate as the raw water is supplied to the nutrient solution tank through the raw water supply pipe.
