FIELD OF THE INVENTION The invention relates to mechanical engineering, in particular, to slot filters for cleaning fuel and oil in ship power plants.

The purpose of the invention is to increase the efficiency of the filtering process, increase the filter life, simplify the design and reduce the complexity of maintenance.

The drawing schematically shows the self-cleaning filter, the total BID.

The filter consists of body 1, cover 2 with cap 3 and storage container 4. Inside case 1, there is a front-end element S, made in the form of a back cone and a cone. Fastener element 5 contains an ugrupy plate ft with color} | trawl opening 7 and peripheral (5 holes 8 to exit the cleaned fuel, pressure plate 9 with holes 10 resting on spring 11. Between the support plate 6 and A set of conical plates 12 inside which squares 13 are located is placed on a horizontal plate 9. The inner edges of the conical plates 12 form a conical surface in the form of an inverse truncated-on cone, thus forming the outer conical surface of the filter element; 5 is inclined to its glue;

, Phew

angle o1 arctg -, where Vrf, - speed about

filtering on the outermost HL L tpx of the filter element, and VQ is the sedimentation rate of the sludge particles. The thrust plate 6 is connected by a rod 14 with an external vibration actuator 15 ..

The centers of the holes U, made in the pressure plate 9, are located around the circumference, the diameter of which is larger than the outer diameter of the smaller base of the clamping element 5.

Inside the housing 1, installed is made in the form of a reverse truncated cone of the fender face} 1a 16, the conicity of which is greater than the conicity of the outer conical surface of the filter element 5.

The housing 1 is provided with a nozzle 17 for entering the fuel, and the cap 3 has a pat6832

cuttings 18 for the release of purified fuel. Shchamosbornik 4 is equipped with a stopper valve 19 and is made with a hole 20 for the release of sludge.

The filter works as follows. Fuel through pipe 17 enters the housing 1, where it moves to the surface of the filter element 5. The fuel passes through the gaps between the conical plates 12 of the filter element 5 and through the peripheral holes 8 and the pipe 17 is removed from the housing 1. Mechanical particles

5, under the action of vibration, are not fragmented into smaller ones and do not pass into the slots between the conical plates 12, are lowered and due to the baffle plate 16 are concentrated in the area of the holes

Q 10 and through them emerge into the cavity of the sludge bed (5 4, from where, through the opening 20, are removed from the filter by periodic rotation of the tap-plug 19 by 90.
