Abstract

Изобретение относи-.с к технике фильтровани жидкостей. Цель изобретени - упрощение конструкции. Фильтр содержит корпус 1 с патрубками 2, 4 и 5, горизонтальную нижнюю перегородку 6 с закрепленными на ней фильтрующими патронами 7. Нижн часть патронов 7 снабжена отверсти ми с запорными клапанами с приводом в виде двух сильфонов, разновеликих по диаметру . Больший сильфон размещен выше меньшего сильфона и снабжен двум горизонтальными стенками и верхн из которых укреплена к нижнему торцу патрона 7, а нижн снабжена клапаном и соединена с меньшим сильфоном. При фильтровании клапан закрывает отверсти под действием избыточного давлени внутри патрона исходной жидкости на нижнюю стенку и упругости стенок большего сильфона. При обратной промывке клапан перемещаетс вверх и открывает отверстие 8 под действием избыточного давлени промывной жидкости снаружи патрона на нижнюю стенку снизу вверх, что вызывает перемещение вверх нижней стенки вместе с указанным клапаном. При этом стенка большего сильфона сжимаетс , а стенка меньшего сильфона раст гиваетс .3 ил. ГThe invention relates to a fluid filtration technique. The purpose of the invention is to simplify the design. The filter includes a housing 1 with nozzles 2, 4 and 5, a horizontal bottom partition 6 with filter cartridges 7 fixed to it. The bottom part of the cartridges 7 is provided with openings with shut-off valves with a drive in the form of two bellows of different size in diameter. A larger bellows is placed above the smaller bellows and is provided with two horizontal walls and the upper one of which is fixed to the lower end of the cartridge 7, and the lower one is provided with a valve and is connected to a smaller bellows. When filtering, the valve closes the holes under the action of overpressure inside the cartridge of the source fluid on the bottom wall and the elasticity of the walls of the larger bellows. During the backwash, the valve moves upwards and opens the opening 8 under the action of overpressure of the washing liquid outside the cartridge to the bottom wall from bottom to top, which causes the bottom wall to move upward along with the indicated valve. In this case, the wall of the larger bellows is compressed, and the wall of the smaller bellows is stretched .3 Il. R

Invention Formula

5 Cartridge filter for cleaning fluid, comprising a housing, a pipe for supplying the source fluid, connected to a collector, nozzles for draining filtrate and contaminants, and a horizontal partition,

0 located under the filter cartridges, communicated by their cavities with the collector and made with openings in the lower ends, which are aligned with which in the horizontal partition are made

5 conical holes and cone stop valves are located and drive them to move vertically, characterized in that, in order to simplify the design and reduce energy consumption by using the energy of the cleaned and washing

fluid, the drive of the vertical movement of the conical shut-off valves is made in the form of bellows of different size along the diameter located between the lower end of each cartridge and the horizontal partition, the larger of which is connected by its upper part through the upper ring-shaped wall with the lower end

the corresponding cartridge around the perimeter of its opening, and the lower part by means of the lower annular horizontal wall, carrying a stop valve mounted on radial rods, with the upper part of a smaller diameter of the background power, reinforced by its lower part on the horizontal partition.
