DRYING SYSTEM Russian patent published in 2016 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to reclamation and may be used both in sprinkling and drying of agricultural lands. Drainage system consists of drains 1, header 2 with drain well 4, inlet connection pipe 9 and air duct 14. In mouth of header 2 there is tank 3 of well 4, in which there is a float drive, made of float 5, connected by rod 6 via hinge with valve 7, arranged on filling hole 8 of inlet connection pipe 9. Valve 7 is equipped with adjustable inclined screw 10, free end of which comes into contact with bottom 11 of well 4. Valve 7 is installed so that its one end is secured by hinge 12 to lower end of inlet connection pipe 9, and its second end articulated via rod 6 is connected with float 5. Head of header 2 comprises insert active nozzle 17, which forms a mixing chamber inlet pipe 9. At joint of active nozzle 17 with inlet branch pipe 9 has adjustment inlet 16. Inlet branch pipe 9 is communicated via air duct 14 with valve 15. Water from collector 2 is fed into insert active nozzle 17, where flow gets high-speed movement and is fed into tank 3 well 4 with high water flow rate. Around case of narrow section of active nozzle 17 as a result of high-speed of water, a vacuum zone is created, in which atmospheric air is sucked, which accompanies mixing with water and increases flow through nozzle 9 and supply into tank 3 of well 4. Such mixing is accompanied by intense aeration of water.

EFFECT: design of system is aimed at improving operating efficiency and reliability.
