Фильтр содержит корпус 1 с патрубками 2 дл подачи исходной жидкости 3 отвода фильтрата и 4 шлама. Дл предотвращени взмучивани осадка предусмотрен отражатель 5.The filter includes a housing 1 with nozzles 2 for supplying the source liquid 3 filtrate drain and 4 sludge. A reflector 5 is provided to prevent the sediment from roiling.

Фильтроэлемент 6 представл ет собой перфорированный цилиндрический каркас, ось которого сориентирована вертикально. Внешн поверхность каркаса покрыта микросеткой . Фильтроэлемент нижним торцом прикреплен (подвешен) к нижнему концу трубки 7, выполненной из упругого материала , например резины. Верхний конец трубки 7 жестко соединен с патрубком 2 дл подачи исходной жидкости. Упруга 25 трубка концентрично .расположена внутри фильтроэлемента.The filter element 6 is a perforated cylindrical frame, the axis of which is oriented vertically. The outer surface of the frame is covered with a microgrid. The filter element is attached to the lower end of the (suspended) to the lower end of the tube 7, made of an elastic material, such as rubber. The upper end of the tube 7 is rigidly connected to the nozzle 2 for supplying the source liquid. Elastic 25 tube concentric. Located inside the filter element.

Вибрационный фильтр работает следую- шим образом.The vibrating filter works as follows.

Исходна жидкость, содержаща твердую фазу, подаетс через патрубок 2 в упругую трубку 7. Под воздействием давлени жидкости диаметр и длина трубки увеличиваютс , что приводит благодар наличию спирали 8 и неподвижному креплению ее на концах трубки 7 к повороту свободного конца трубки и закрепленного на нем фильтроэлемента 6 вокруг его оси. При достижении определенного давлени , определ емого настройкой клапана пб удлинению упругой трубки, Фильтроэлемент 6 и седло клапана 9 смешаютс вниз, открыва клапан. При этом жидкость из трубки резко сбрасываетс через клапан в корпус фильтра на отражатель 5. Давление в трубке снижаетс , и под 2Q действием сил упругости трубки фильтро- элемент и седло клапана возвращаютс в исходное положение, закрыва клапан.The initial liquid containing the solid phase is fed through the nozzle 2 into the elastic tube 7. Under the influence of the liquid pressure, the diameter and length of the tube increase, which results due to the presence of the spiral 8 and its fixed attachment at the ends of the tube 7 to the rotation of the free end of the tube and the filter element fixed on it 6 around its axis. When a certain pressure is reached, as determined by the valve setting pb of the elongation of the elastic tube, the filter element 6 and the valve seat 9 mix down, opening the valve. At the same time, the liquid from the tube is abruptly dropped through the valve into the filter housing on the reflector 5. The pressure in the tube decreases, and under 2Q the elastic force of the tube causes the filter element and the valve seat to return to their original position, closing the valve.

Затем цикл повтор етс , обеспечива одновременно поступательное виброударное движение и угловую вибрацию фильтроэлемента относительно его оси.Then the cycle repeats, simultaneously providing translational vibro-impact movement and angular vibration of the filter element about its axis.

Этим достигаетс интенсивна непрерывна регенераци сетчатого полотна, котора также увеличиваетс благодар пульсацион- ному движению жидкости в зазоре между корпусом и движущимс фильтроэлементом.This results in intensive continuous regeneration of the mesh fabric, which also increases due to the pulsating movement of the fluid in the gap between the casing and the moving filter element.

Claims

1. A vibration filter comprising a housing with fittings for supplying the original

at the free end, for example, re-40 liquids and removal of filtrate and sludge.

Zine tubes, with pressure in the tube

Ikg / cm from the angle of winding 6 (1 - with a tube with an external diameter of 7 mm and a wall thickness of 1 mm with winding of mylar thread;

II- with a tube with an outer diameter of 14 mm

and a wall thickness of 2 mm with 45 steel wire wound).

The optimum angle of rotation of the filter element is the range of the angle of winding 60-70 °. Low values of the rotation angle at small winding angles are explained by a small number of turns per unit length of the tube. At winding angles close to 90 °, the number of turns is greatest, but the angle of rotation of the filter element is insignificant due to the predominance of large axial and small radial deformations of the tube. At a winding angle of about 55 °, both dependences have a dip, since in this case the direction of winding coincides with the component ring 50

out and longitudinal tube stresses and virtually eliminates the change in tube length and diameter.

The vibrating filter works as follows.

The initial liquid containing the solid phase is fed through the nozzle 2 into the elastic tube 7. Under the influence of the liquid pressure, the diameter and length of the tube increase, which results due to the presence of the spiral 8 and its fixed attachment at the ends of the tube 7 to the rotation of the free end of the tube and the filter element fixed on it 6 around its axis. When a certain pressure is reached, as determined by the valve setting pb of the elongation of the elastic tube, the filter element 6 and the valve seat 9 mix down, opening the valve. At the same time, the liquid from the tube is abruptly dropped through the valve into the filter housing on the reflector 5. The pressure in the tube decreases, and under Q, due to the elastic forces of the tube, the filter element and the valve seat return to their original position, closing the valve.

Then the cycle repeats, simultaneously providing translational vibro-impact movement and angular vibration of the filter element about its axis.

This results in intensive continuous regeneration of the mesh fabric, which also increases due to the pulsating movement of the fluid in the gap between the casing and the moving filter element.
