HYDROPONIC SYSTEM FOR VEGETABLE PRODUCTION

摘要

This utility model relates to a hydroponic system for production of vegetable crops, which finds application in vegetable growing. Thus created hydroponic system for production of vegetable crops includes three functionally linked knots, such as heated reinforced concrete floor (12), recycling system with UV sterilizer (8) and feeding knot. The heated reinforced concrete floor (12) is separated into sectors with placed on them growth vessels (13), and is tilted towards the collector channel (18), built in the middle of the floor. Under each sector of the concrete floor (12) are formed drainage shafts (14), connected with the collector channel (18), as each drainage shaft (14) is linked via a valve (15) to drainage pipe (16) and filler pipe (17). The drainage pipe (16) is connected to reservoir (1) for drainage water, and the filler pipe (17) is connected to mixing vat (6). The feeding knot includes two reservoirs (10) for feeder solutions A and B and reservoir (11) for acidic solution, and is fitted with first sensor (4) for saline concentration of the solution and sensor (5) for the Ph. of the solution. The first sensor (4) and sensor (5) are connected to controller (7), as well as to the first filter (3). The recirculation system includes first pump (2) and second filter (3), placed between the reservoir (1) for drainage water and the UV-sterilizer (8), and second pump (2), placed next to the mixing vat (6). Next to the second filter (3) and the second pump (2) are located the second and third sensors (4) for saline concentration, connected to the controller (7), thus the components of the system are connected via PVC pipelines
