PLANT FOR PURIFICATION OF WATER AND NUTRITIOUS MIXTURE SOLUTIONS, MAINLY FOR DRIP IRRIGATION Russian patent published in 2005 - IPC

FIELD: agricultural reclamation; drip irrigation; purification of water and nutritious mixtures at irrigation of vegetables, vineyards, gardens, forest nurseries, fruit and berry plantations.

SUBSTANCE: proposed plant includes hermetic reservoir filled with filtering material and mounted horizontally, upper and lower distributing systems for delivery of water from water basin and discharge of cleaned water and contaminant discharge line. Plant is provided with hermetic reservoir for nutritious mixture solutions, hydraulic cyclones, pneumo-hydraulic accumulator and two-position distributor for water and nutritious mixture solutions. Upper and lower distributing systems of hermetic reservoir are connected by means of two-position water flow distributor with contaminant discharge line and hydraulic cyclones mounted at inlet and outlet. Mounted in cavities of hydraulic cyclones are self-cleaning screen filters. Bottom parts of hydraulic cyclones are engageable with contaminant receivers. Hermetic reservoir for nutritious mixture solutions is hydraulically connected by means of valves with pressure pipe line of hydraulic cyclone and with contaminant discharge line through upper cavity of water and nutritious mixture solution distributor. Body of two-position water flow distributor is hydraulically connected with upper and lower distributing systems by means of branch pipes for delivery of water from water basin and discharge of cleaned water, contaminant discharge line and hydraulic cavity of pneumo-hydraulic accumulator. Membrane of pneumo-hydraulic accumulator is kinematically linked with plunger of two-position water flow distributor.

EFFECT: low cost of products; enhanced operational reliability; reduced consumption of labor for serving the plant.
