Abstract

Изобретение относитс к сельскому хоз йству . Сущность изобретени : в корпусе 1 тангенциально установлен патрубок 2 подвода исходных стоков. Полый цилиндрический фильтрующий элемент 7 снабжен средством его очистки, которое выполнено в виде набора щеток39. Щетки 39 снабжены приводом и при работе электродвигател 13 вал 11 со щетками 39 вращаетс . После очистки элемента 7 вакуум в патрубке 4 слива фильтрата исчезает. Датчик вакуума 6 размыкает цепь системы управлени электродвигателем 37. Узел отвода мелких и плавучих взвесей выполнен в виде замкнутого транспортера 17. Съемные пластины 28 сдвигают всплывшие примеси с поверхности жидкости и сбрасывают в лоток 26. 3 з.п.ф-лы, 3 ил.This invention relates to agriculture. Summary of the Invention: In the housing 1, a branch pipe 2 supplying initial wastewater is tangentially mounted. The hollow cylindrical filter element 7 is provided with a means for cleaning it, which is made in the form of a set of brushes39. The brushes 39 are driven and, when the electric motor 13 is running, the shaft 11 with the brushes 39 rotates. After cleaning the element 7, the vacuum in the nozzle 4 of the filtrate drain disappears. The vacuum sensor 6 opens the circuit of the motor control system 37. The fine and floating suspension removal unit is designed as a closed conveyor 17. Removable plates 28 shift the floating impurities from the surface of the liquid and drop them into the tray 26. 3 cpf, 3 sludge.
