Abstract

Изобретение относитс к фильтрам дл очистки жидкостей и позвол ет повысить качество регенерации. Фильтр содержит корпус 1 с патрубками, подвижную верхнюю и неподвижную нижнюю перегородки с укрепленными на них нит ми, поплавок 7, соединенный гибкими св з ми 8 с верхней перегородкой. На поплавке подвешен тарельчатый клапан 9. Поплавок снабжен фиксаторами верхнего и нижнего положени в виде упругих фигурных пластин, взаимодействующих с выступами 18 направл ющих стержней 14. При регенерации в результате повышени уровн жидкости поплавок 7 срываетс с фиксации в нижнем положении и поднимает верхнюю перегородку и нити с одновременным их встр хиванием и полосканием, а также открывает клапан 9. При этом поплавок фиксируетс в верхнем положении верхними пластинами. При падении уровн жидкости поплавок под действием собственной массы падает, а клапан 9 закрывает отверстие патрубка 10. 2 з.п. ф-лы, 4 ил.The invention relates to filters for cleaning liquids and improves the quality of regeneration. The filter includes a housing 1 with nozzles, a movable upper and fixed lower partitions with threads fastened on them, a float 7 connected by flexible couplings 8 to the upper partition. The flap valve 9 is suspended on the float. The float is provided with upper and lower locks in the form of elastic shaped plates that interact with the projections 18 of the guide rods 14. During regeneration as a result of an increase in the liquid level, the float 7 breaks down in the lower position and lifts the upper partition and the threads with simultaneous shaking and rinsing, and also opens the valve 9. At the same time, the float is fixed in the upper position by the upper plates. When the liquid level falls, the float falls under the action of its own weight, and the valve 9 closes the opening of the nozzle 10. 2 CW f-ly, 4 ill.

Claims

Claim

1. Filter for cleaning liquids, comprising a housing with a bottom and a nozzle for supplying the cleaned fluid and draining the filtrate and sludge, the upper movable and lower fixed perforated partitions, the filtering layer of filaments,

attached to partitions, and a device for regeneration, including a float attached to the upper partition ·, and means for dosed discharge of fluid, characterized in that, in order to improve the quality of regeneration, the pipe for discharge of sludge is attached to the bottom of the case, and means for dosed discharge the fluid is made in the form of a poppet valve installed in this nozzle, connected by means of a flexible coupling and a tension spring to the float, and clamps of the upper and lower position of the float, made in the form of ikreplennyh to a float rod with the tabs and elastic shaped plate, interacting with the projections.

2. Filter pop. 1, which is distinguished by the fact that it is provided with rails located in the housing and attached to the nozzle for the discharge of sludge.

3. Filter pop. 1, characterized in that the float is made with openings in which rods are located.
