(54) FILTER REFLECTOR

(57) The invention relates to filtration, namely to liquid filters with centrifugal regeneration.

filtering surface, and can be used in various industries. The purpose of the invention is to increase the performance of the filter. The filter consists of a housing 1 with a source liquid supply nozzle 2, a filtering element 3, a sprinkler 6 mounted on a hollow rotating shaft 5 with source liquid supply openings B and connected to a drive 15. A distinctive feature of the filter is that the sprinkler 6 is made - a view of the screw surface, and the filtering element is installed with the possibility of coaxial rotation with respect to the sprinkler. 1 il.

The invention relates to filtration, in particular to liquid filters with centrifugal regeneration of the filtering surface, and can be used in engineering, mining, food, chemical and other industrial sectors.

The purpose of the invention is to increase the filter performance.

The drawing shows the proposed filter, a general view.

The filter consists of a cylindrical housing I with a nozzle 2, providing the flow of fluid into the filter. A filtering element 3 is placed in the housing, which is advisable to be in the form of a truncated cone. The inner surface of the filtering element 3 is encircled with filtering cloth A. A hollow shaft 5 is placed inside the filtering element. A sprinkler 6 is rigidly attached to the shaft 5, made in the form of a surface, which is advisable to fit over the truncated cone. Radial vanes 7 are installed uniformly at the same distance from each other on the surface of the sprinkler 7. Radial holes 8 are made above the upper part of the sprinkler to supply the filtering liquid to the inner surface of the filter element. A guide partition 9 is installed under the surfaces in the hollow shaft. In the lower part of the housing there is a filtrate collection chamber 10 with holes 11 for draining the filtrate. A device 12 is installed under the filter element to remove solid sediment from the filter. Below the device 12 there is a reservoir I3 for the liquid medium that has entered it with its outlet 14 for this liquid. The hollow shaft is connected to the drive 15 via a gear cylindrical wheel 16 fixed on it and a gear wheel 17 of a block of 18 gear wheels. The upper part of the filter element is attached to a gear wheel 19 mounted on a bearing 20 mounted on a rotating shaft between the support ring 21 and the shoulder of the rotating shaft, which is connected to the drive through gear 22 of the gear block. The bottom part of the filter element is mounted on the bearing 23.

The filter works as follows.

The drive 15 through the gears block 18 and the gear wheels 1 and 19 simultaneously drive the counterclockwise rotation of the hollow shaft 5 and the filter element 3. At the same time, their rotation speed is different. The filter element rotates on bearings 20 and 23 coaxially relative to the rotating shaft 5 at a lower speed, VeM hollow rotating shaft 5 with a sprinkler 6. The initial fluid, falling on the guide wall 9, is ejected through the holes 8 on the surface of the sprinkler 6, trapped radial vanes 7 and is dropped onto the cone-shaped filter element 3.

The fluid under the action of centrifugal force and the impact of the filter element 3 passes through it into the cavity of the housing I, the stack into the collecting chamber 1P of the filtrate, and through the holes 1 1 fi 1 day drains out Solids and part of the liquid that does not pass through the filter element 3, having reflected at an angle from the impact and under the action of gravity forces, they return to the turns of the surface of the sprinkler 6, bent along a helical line, and the blades 7 on it are thrown under the action of centrifugal force on the filter element 3, repeating such throws on the filter element 3 to the lower end of the screw surface of the sprinkler 6. By rotating the screw surface of the sprinkler 6 relative to the filter element 3, the initial liquid is sprayed over the entire surface of the filter element 3, and not as black as in the prototype.

By striking the filter element 3, the dehydrated solids enter the sludge removal device 12 and are carried outside. A portion of the liquid that enters the tank 13 during the operation of the filter is removed from the outlet 14 through it.

The invention provides full use of the filtering surface for cleaning the source liquid with its separation into liquid and solid fractions, i.e. increases the efficiency of the filter by 2 times.
