DEVICE FOR GALVANOCHEMICAL TREATMENT OF SEWAGE Russian patent published in 2003 - IPC

FIELD: decontamination of runoffs of various chemical processes from heavy metals, cyanides, oil, petroleum and other admixtures. SUBSTANCE: proposed device has housing made in form of cylindrical reservoir with bounding grates located inside cylinder in parallel with its end faces and with side water supply and discharge branch pipes. Device is provided with mechanism for motion of reservoir in three planes; said mechanism is made in form of swinging hollow rectangular levers provided with axles and forks for their rotation on drive and driven shafts; ratio of lever lengths is equal to a:b: c: e = 1:1:1:1:7, where a is radius of swinging of drive shaft levers; b is distance between planes of location of axes of hollow branch pipes; c is radius of swinging of driven shaft lever; e is distance between parallel axes of drive and driven shafts. Inclination of base of device is regulated by means of screw. Drive and driven shafts are hollow. EFFECT: low cost; enhanced efficiency. 3 cl, 2 dwg
