Description

The mixer of mineral fuel and vegetable oil with an active drive belongs to the field of automobile and tractor construction and can be used in the power supply system of diesel engines of automotive engineering (tractors, automobiles, combines, etc.).

Known mixer of mineral fuel and vegetable oil with an active drive [Patent No. 1472003 of the Russian Federation, IPC А01J 11/16. A device for the homogenization of whole milk replacer / V.A. Startsev, V.V. Startseva, V.A. Ivanov; Altai Research and Design and Technological Institute of Livestock. - №4244351, Appl. 05/15/1987. Publ. 04/15/1989], consisting of a housing with inlet and outlet nozzles. Inside the housing are coaxially rotors with a drive. The lower rotor has internal blades located in its central part, and two cylinders located between the cylinders of the upper rotor. In addition, on the outer surface of the outer peripheral cylinder between the holes, made with a slope to the radius, are blades with slots parallel to the base of the cylinder and alternating in staggered order with respect to the slots of adjacent blades. In this case, the holes are made perpendicular to the surfaces of the blades facing the hole.

Mixing occurs due to the fact that the mixture entering through the inlet nozzle into the internal zone of the mixer under the action of the pressure created by the internal vanes passes through the slots and openings of the cylinders rotating in opposite directions by the rotor. After that, the mixture is removed from the mixer outlet pipe.

The disadvantage of the mixer is not high-quality mixing of mineral fuel and vegetable oil due to the formation of foam in the prepared mixture.

Known mixer of mineral fuel and vegetable oil with an active drive [A. 1406867 of the Russian Federation, MKP B01F 5/00. Mixer / L.I. Pishchenko, A.A. Shurpach, A.M. Golovko. No. 4052321/26, Appl. 04/08/1986; Publ. 27.09.1997], comprising a housing with nozzles for input of components and output of the mixture, a main impeller and an additional impeller connected by means of a shaft to the drive.

Mixing occurs due to the fact that cavitation bubbles are formed on the impeller, the growth and collapse of which form cumulative microjets that have a mixing effect on the substances being processed.

The disadvantage of the mixer is insufficient mixing of mineral fuel and vegetable oil due to the formation of foam in the prepared mixture.

Of the known, the closest in technical essence is a mixer of mineral fuel and vegetable oil with an active drive [RF Patent 2503491, MKP B01F 5/06. Mixer of mineral fuel and vegetable oil with an active drive / A.P. Ukhanov, D.A. Ukhanov, E.A. Sidorov, E.A. Khokhlova. - №2012128420/05, Appl. 05.07.2012; Publ. 10.01.2014], comprising a housing with connections for input of components and output of the mixture, the main impeller rigidly mounted on the drive shaft, an additional impeller kinematically connected to the drive shaft through a planetary gear, the carrier of which is rigidly connected to the additional impeller, and the sun gear mounted on the splines rear end of the drive shaft.

Mixing of mineral and vegetable components occurs due to the different frequency of rotation of the main and additional impellers. The disadvantage of the mixer is insufficient mixing of mineral fuel and vegetable oil due to the formation of foam in the prepared mixture.

The present invention aims to eliminate the noted disadvantage and from its application the following result is obtained: improving the quality of mixing of mineral fuel and vegetable oil by eliminating the foaming formed during the mixing process of mineral and vegetable components.

This technical result is achieved due to the optimal ratio between the rotational speed of the main impeller and the rotational speed of the additional impeller, while the shaft of the main impeller is driven from a low-speed electric gearmotor.

FIG. 1 shows a diagram of a mixer of mineral fuel and vegetable oil with an active drive.

Mixer mineral fuel and vegetable oil with an active drive, comprising a housing 1 with nozzles input components 2 and 3 and output mixture 4, the main impeller 5, rigidly mounted on the shaft 6 of the drive 7, additional impeller 8, kinematically connected to the shaft 6 of the drive 7 through the planetary the transmission, which drove 9 is rigidly connected to the additional impeller 8, and the sun gear 10 is installed on the splines of the rear end of the shaft 6 of the drive 7, while the drive 7 of the shaft 6 of the main impeller 5 is from the gearmotor 11, electrically and connected via a switch 12 to a constant current source 13 with a voltage of 12 V., the rotational speed of the main impeller 5 is 45-65 rpm, and the rotational speed of the additional impeller 8 differs from the rotational speed of the main impeller 5 by the value of the gear ratio of the planetary gear equal to 1.36-1.42.

Works mixer of mineral fuel and vegetable oil with an active drive as follows.

Switch 12 connects the electrical circuit of the motor-reducer 11 to the current source 13, which causes the main and additional impellers 5 and 8 to rotate. Mineral fuel and vegetable oil through the inlet pipes of components 2 and 3 enter the mixer, where due to the optimal difference between rotational frequencies the main and additional impellers 5 and 8 there is a qualitative mixing of the mineral and vegetable components without the formation of foam in the prepared mixture. The finished mixture (mixed fuel) out of the mixer through the outlet of the mixture 4.

The prepared mixture without foam, in case of installation of the claimed mixer in a two-tank (tank for mineral fuel and tank for vegetable oil) diesel power supply system, will ensure stable and uninterrupted operation of the engine on the mixed fuel without disturbing the continuity of its flow into the combustion chamber.

The claimed invention is technically feasible, the mixer is manufactured and tested. FIG. 2 shows a prototype of a mixer of mineral fuel and vegetable oil with an active drive; in fig. 3 - experimental setup for testing the performance of the mixer and the quality of the prepared mixture.
