Description

The invention relates to a device for cleaning liquid fuel and preparing it for combustion.

A device for cleaning and preparing liquid fuel for combustion [1], comprising a filter element in the form of a truncating cone expanding downward, located in a housing equipped with a cover, magnets in the form of a coil having the shape of a truncated cone expanding toward the top, an inlet fitting with a threaded slot , an outlet pipe located tangentially to the body, and a pipe for contaminant discharge with a threaded slot, on the bottom of the body, a settler made of non-magnetic material is fixed, having the shape of a funnel facing down a narrow h Accordingly, the inlet fitting is placed in the cover along the housing axis, the discharge pipe is installed at the bottom of the sump, and its upper end is placed at the bottom of the housing, the outlet pipe for the outlet of purified fuel is located tangentially at the bottom of the housing, and in the annular gap in parallel between the filter an element and an inner surface of the housing and magnets are fixed at the bottom of a plate of non-magnetic material, made in the form of a truncated cone, and its upper edge is located from the lid at a distance equal to 0.15 ... 0.25 height to oppus, casing in the form of a cone expanding upwards.

The known device has disadvantages: when entering through the inlet fitting with a threaded slot, the fuel receives a powerful rotational impulse, centrifugal forces arise, under which impurities in the form of solid particles and water are thrown onto the grid and lowered into the sump. The action of centrifugal forces is limited by the height of the threaded gap and after it the centrifugal field is greatly weakened. The small volume of the sump does not allow the complete deposition of impurities and they are partially “washed out” of it and fall back inside the filter. The conical shape of the casing is structurally more complicated than the cylindrical one in manufacturing and requires additional funds when mounted on an engine.

The purpose of the invention is to improve the quality of cleaning, preparing fuel for combustion and increasing the life of the device.

This goal is achieved by the fact that between the lower part of the casing and the upper part of the sump place a support ring with radial slots. Between the lower part of the inlet fitting with a threaded slot and the support ring with radial slots, a conical hollow rotor with a helical tape is installed on the outer surface.

Figure 1 shows a General view of the device, and figure 2 is a view A. A device for cleaning and preparing liquid fuel for combustion consists of a housing 1 provided with a cover 2, a filter element 3 in the form of a truncated cone expanding downward, magnets 4, input a fitting with a threaded slot 5, an outlet pipe 6 located tangentially to the lower part of the housing 1. At the bottom of the housing 1, a sump 7 is installed. At the bottom of the sump 7 there is a nozzle for discharge of pollution 8 with a tap 9 for automatic discharge of pollution. Between the lower part of the housing 1 and the upper part of the sump 7 there is a support ring 10 with radial slots. Between the lower part of the inlet fitting with a threaded slot 5 and a support ring 10 with radial slots, a conical hollow rotor 11 with a helical tape 12 is installed on its outer surface.

In the annular gap between the filter element 3 and the magnets 4 parallel to their inner surface at the bottom of the housing 1 is fixed a plate 13 of non-magnetic material made in the form of a truncated cone. In the sump 7, the upper and lower sensors 14 of the pollution level are installed, an electronic device 15 for automatically controlling the opening of the tap to drain them. On the outer surface of the magnets 4 mounted casing 16 of a cylindrical shape.

A device for cleaning and preparing liquid fuel for combustion works as follows. The fuel through the inlet fitting with a threaded slot 5 is fed into the housing 1, passing through the threaded slot, acquires a rotational movement, while centrifugal forces arise that reject solid particles and water droplets (not passing through the filter element and with a density greater than fuel) to the filter element 3 and under the influence of gravity fall into the sump 7.

The presence of a freely rotating hollow conical rotor 11 allows you to extend the action of centrifugal forces along the entire length of the housing due to the ingress of a fuel jet on the surface of the rotor with a screw-like tape on the outer surface and its unwinding (operation of the centrifuge) from the nozzle 5 with a threaded slot, which makes up a third of the length of the housing, supporting a ring with slots 10 at the bottom of the housing slows down the rotation of the fuel flow after the conical rotor 11 and the heavier contaminants sink into the sump 7, forming a conductive medium. When the upper level sensor 14 is reached using the electronic device 15, the valve 9 automatically opens and contaminants are removed to a nearby container. The shape of the casing 16 is cylindrical, which simplifies the design and installation of the filter.

The use of a freely rotating conical rotor with a helical tape on a surface parallel to the casing allows quick spinning of the rotor and supporting the action of centrifugal forces along the entire length of the casing.

The presence of radial slots in the support ring allows you to dampen the rotational movement of the suspension flow at the bottom of the housing and it fills the sump under the action of gravity, forming a conductive medium.

When the sump is filled with contaminants to the level of the upper sensor, an electronic device is activated and they are removed through a tap. The device can be used as part of internal combustion engines of both diesel and carburetor.
