(54) БАРАБАННЫЙ ФИЛЬТР(54) DRUM FILTER

1one

Изобретение относитс к барабанным фильтрам дл разделени суспензий, а именно к барабанным фильтр-прессам дл фильтровани навоза.The invention relates to drum filters for separating suspensions, namely drum filter presses for filtering manure.

Известен барабанный фильтр, содержащий вращающийс фильтрующий барабан с наружной перфорированной рабочей поверхностью , выполненной в виде продольных р дов прорезей, и трубу дл отвода фильтрата , установленную неподвижно, причем на внутренней стороне торцовых стенок барабана выполнены профилированные пазы, а труба снабжена направл ющими, на которых подвижно установлена пластина, несуща ролики, вход щие в пазы, ,и зубь , сопр женные по щирине с прорез ми барабана 1.A drum filter is known, comprising a rotating filter drum with an outer perforated working surface made in the form of longitudinal rows of slits, and a pipe for draining the filtrate fixedly mounted, the profiled grooves being made on the inside of the end walls of the drum, and the pipe is provided with guides on which the plate is movably mounted, carrying the rollers entering into the grooves, and the teeth that are wired across the slots of the drum 1.

Недостатками устройства вл ютс слОж ность и металлоемкость конструкции.The drawbacks of the device are the complexity and metal content of the structure.

Известен барабанный фильтр, содержащий горизонтальный цилиндрический корпус размещенный по оси корпуса вал, закрепленный на валу перфорированный фильтрующий барабан, установленный над корпусом, отжимные валки, расположенные под валками снаружи корпуса нож дл сн ти осадка и лоток дл слива фильтрата 2.A drum filter is known, comprising a horizontal cylindrical body located along the axis of the body, a perforated filter drum mounted on the shaft, mounted over the body, squeezing rolls located under the rollers outside the body of the knife to remove sludge and a tray to drain the filtrate 2.

Недостатком устройства вл етс значительна металлоемкость конструкции и .малоэффективна очистка фильтрующего элемента.The drawback of the device is the significant metal consumption of the structure and the low-efficiency cleaning of the filter element.

Цель изобретени - повышение эффек5 тивности очистки фильтрующего барабана. Указанна цель достигаетс тем, что фильтр снабжен дополнительными кольцами , размещенными между основными, при этом кольца установлены с возможностью ,Q осевого и радиального перемещени .The purpose of the invention is to increase the efficiency of cleaning the filter drum. This goal is achieved by the fact that the filter is equipped with additional rings placed between the main ones, and the rings are installed with the possibility, Q axial and radial movement.

Причем фильтр снабжен размещенным под фильтрующим элементом приводом перемещени колец, выполненным в виде вращающегос валика с закрепленными на нем разнозаходными спирал ми.Moreover, the filter is provided with a drive for moving the rings arranged under the filter element, made in the form of a rotating roller with different spirals attached to it.

15При этом дополнительные кольца выполнены волнообразными.15When this additional rings are made wavy.

Claims

20Drum, filter contains horizon. tal cylindrical body 1, shaft 2 located along the body axis, perforated filter drum 3 fixed on the shaft, squeeze rolls 4 mounted above the body, knife 5 placed under the rollers outside the body to remove sediment and tray 6 to drain the filtrate. The filter is provided with fingers mounted for movement in a horizontal direction on the filter drum, one of the rings being wavy 7 and arranged in alternating sequence with flat rings 8. The filter is equipped with a ring driving drive placed in the form of a rotating roller 9 and fixed there are different spirals on it 10. To prevent axial movements of the rings, restrictive rings 11 and 12 are installed on the drum. The drum filter uses the following m way. The initial suspension is supplied under pressure to the filtering surface of the drum 3, where, under the action of squeezing rolls 4, the suspension is separated into a solid and a liquid phase. The precipitate is removed from the surface of the drum by the knife 5 and removed from the filter. The filtrate, which has passed into the cavity of the drum, is partially discharged through the nozzle at the end of the drum and partially returns through the perforated drum 3 and enters the rings of the filter element. When the profiled rotating roller 9 is rotated, the relative movement of the rings takes place both in the radial and axial directions. Thus, the flow of filtrate and the relative movement of the rings promotes self-cleaning of the filter element from the entrained particles. The invention allows to achieve an intensive self-cleaning of the filter element and a decrease in the metal consumption of the structure. Claims. A drum filter containing a horizontal cylindrical filter element made of rings and a regenerating device, characterized in that, in order to increase the efficiency of cleaning the filter element, the filter is equipped with additional rings placed between the main ones, while the rings are installed with the possibility of axial and radial movement . 2. The filter according to claim 1, characterized in that it is provided with a drive for moving the rings placed under the filter element, made in the form of a rotating roller with different spirals attached to it. 3. The filter according to claim. 1, characterized in that the additional rings are wavy. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 490484, cl.
