The filtering element is installed on the axle by means of translational movements. A cylindrical spring acts upon a lower portion of the filtering element, a bushing abutting the filtering element with its lower end moves freely along the upper axle end. A rod of an electromagnet is driven into the upper end of the bushing, the electromagnet is secured to the external surface of the mixing filter body.

Description

The filter-mixer of two-component fuel belongs to the field of automobile and tractor engineering and can be used in the power supply system of automotive engines.

Known filter mixer of two-component fuel [Patent No. 2365406 of the Russian Federation, IPC B01F 11/00. Vibratory mixer / I.M. Efremov, V.V. Safon: State educational institution of higher professional education "Bratsk State University". - No. 2008110289/15. - Application. 03/17/2008. - Publ. 08/27/2009. - Bull.№24], comprising a housing with input and output channels, a vibrator screw mounted on rolling bearings, an eccentric mechanism.

Mixed components through the inlet channel enter the internal cavity of the housing. Mixing occurs due to the screw-vibrator, driven into rotational and reciprocating motion. The resulting mixture enters the outlet channel.

The disadvantage of a bicomponent fuel filter mixer is the poor mixing of the components, as well as the insufficient degree of purification of the bicomponent fuel during the mixing process.

Of the known devices, the closest in technical essence is a filter-mixer of two-component fuel [Ershov B.V. Truck ZIL-130 / B.V. Ershov, M.V. Zaletaev. - M .: Transport, 1967. - P.63-64], containing a housing with inlet and outlet channels, a glass, a filtering element, which is a set of pairwise plates, one of which has a smooth surface, the other has protrusions.

During the operation of the motor tractor engine, the mixed components through the inlet channel by gravity enter the internal cavity of the filter housing. Due to the vacuum created by the fuel pumping on the suck of the fuel system, the mixture passes through the filter element, is cleaned and enters the outlet channel.

The disadvantage of a bicomponent fuel filter mixer is the poor mixing of the components, as well as the insufficient degree of purification of the bicomponent fuel during the mixing process.

The present invention is aimed at eliminating the noted drawbacks and the following technical result is obtained from its use: the quality of mixing and the degree of purification of the components of the mixed fuel are improved due to the oscillatory motion of the mixed components caused by the reciprocating movement of the filter element.

The specified technical result is achieved due to the fact that the filter-mixer of two-component fuel contains a housing with inlet and outlet channels, a glass, a filter element, which is a set of pairwise plates, one of which has a smooth surface, the other has protrusions, and there is a hollow axis inside the glass with an output channel and two radial holes located in mutually perpendicular planes, the filter element is mounted on the axis with the possibility of reciprocating movement, while a cylindrical spring acts on the lower part of the filtering element, the sleeve moves freely along the upper end of the axis, resting against the filtering element on the lower end, the rod of the electromagnet mounted on the outer surface of the filter mixer body is screwed, the electromagnet circuit is electrically connected to the electronic control unit, equipped with regulators of the frequency and pulse duration of the output signal.

Regulators of the frequency and duration of the pulse of the output signal of the electronic control unit allow you to change the frequency and duration of the oscillations of the filter element.

Figure 1 shows a diagram of a filter-mixer of two-component fuel.

A bicomponent fuel filter mixer comprising a housing 1 with input 2 and output 3 channels, a cup 4, a filter element 5, which is a set of pairwise plates, one 6 of which has a smooth surface, the other 7 has protrusions, and inside the cup 4 there is a hollow axis 8 with an output channel 9 and two radial openings 10, 11 located in mutually perpendicular planes, the filter element 5 is mounted on the axis 8 with the possibility of reciprocating movement, while on the lower part of the filter element 5 in the coil spring 12 operates, the sleeve 13 moves freely along the upper end of the axis 8, rests against the filter element 5 with the lower end, the rod 14 of the electromagnet 15 screwed onto the outer surface of the housing 1 of the filter mixer is screwed to the upper end of the sleeve 13, the electromagnet chain 15 is electrically connected to an electronic control unit 16, equipped with frequency controllers 17 and pulse width 18 of the output signal.

Works filter mixer two-component fuel as follows.

When the autotractor engine operates, two components, for example mineral fuel and vegetable oil, by gravity flow through channels 2 and 3 into the internal cavity of the cup 4, in which they are pre-mixed. At the same time, the electronic control unit 16 supplies a single voltage pulse to the circuit of the electromagnet 15, the rod 14 of which through the sleeve 13 acts on the filter element 5, moving it down the axis 8, compressing the spring 12. When a voltage pulse is applied to the electromagnet 15, its winding de-energized and the rod 14 is retracted into the electromagnet 15, and the filter element 5 due to the elastic force of the spring 12 is returned to its original position. As the unit and zero voltage pulses arrive in the electromagnet circuit, the filter element 5 makes reciprocating movements, causing oscillatory movements of the mixed components of the mixed fuel. The frequency of oscillations and the duration of the pulses are changed by the regulators 17 and 18. The oscillatory movement of the mixed components of the mixed fuel provides a more uniform distribution of their flows throughout the volume of the mixture, eliminating the formation of "stagnant zones" in the mixing process. In addition, the self-cleaning of the filter element 5 occurs. Due to the vacuum generated by the fuel pump of the fuel system, the diesel mixed fuel passes through the gaps between the plates 6 and 7 of the filter element 5, is cleaned of mechanical impurities and through the radial holes 10, 11 of the hollow axis 8 arrives at the output channel 9.
