Multicyclone air cleaner for engine The utility model relates to mechanical engineering, mainly to

engine building, in particular to air cleaners for internal combustion engines.

Known multi-cyclone air purifier containing a countercurrent cyclone unit, cyclone tubes which are located around the discharge pipe and communicate with the hopper, and the cleaned air pipe with the discharge pipe. (Glybin A.I. “Autotractor filters. Handbook, L., Mechanical Engineering, 1980, p. 92).

A disadvantage of the known design is the poor layout capabilities for the vehicle and the lack of an organized intake of air from the zone with the lowest dust content.

The closest, in combination of essential features, to the claimed technical solution is a multicyclone air cleaner for an internal combustion engine, comprising a housing,

exhaust pipe, dust hopper, separation elements, including air flow swirls with exhaust pipes

purified air located concentrically around the outlet pipe, cyclone tubes interconnected to form a closed cavity, the larger base oriented towards the dust collector, and the smaller base covering the exhaust pipe (RF patent No. 2020255, M class. F 02 M 35/02) .

internal combustion

/ A disadvantage of the known air purifier is the complexity

design, insufficient air purification efficiency, as well as limited layout options.

The task was to create a multicyclone air purifier of a simple design, which provides high efficiency of air purification from impurities and improve its layout capabilities.

The problem is solved due to the fact that in the multi-cyclone air cleaner for an internal combustion engine containing a housing, a discharge pipe, a dust collection hopper, separation elements including cyclone tubes, flow swirls with purified air pipes, the housing is made in a rectangular shape, while one of the end sides made with the possibility of air intake, for example, mesh, and the upper and lower bases are made with holes located in a checkerboard pattern in which are installed, respectively Twain purified air outlet tube and cyclone tube, in addition, a discharge pipe is attached on the lid, which is mounted on the upper base, forming a cavity for cleaned air and a dust hopper provided with a nipple valve.

Analysis of known technical solutions for scientific, technical and patent documentation showed that the set of essential features of the proposed solution was not previously known, therefore, it meets the condition of “novelty.

The utility model is illustrated by drawings:

figure 1 - multicyclone air purifier for two in section;

figure 2 is a section aa in figure 1;

Fig.Z - installation of an air cleaner on a car.

The multicyclone air cleaner comprises a housing 1, a dust collecting hopper 2, a cover 3, and separation elements.

The housing 1 has a rectangular shape, while its upper base 4 and lower base 5 are made with holes arranged in a checkerboard pattern, and one end face 6 is mesh with air intake.

The separation elements include cyclone tubes 7 into which blade vortexes 8 of the air flow and tubes 9 of the cleaned air outlet are installed.

Cyclone tubes 7 are installed in the holes of the lower base 5 and communicate with the hopper 2, fixed to the lower base 5.

Tubes 9 for cleaning the cleaned air are installed in the holes of the upper base 4 and communicate with the cavity 10 for cleaned air, which is formed by a cover 3 fixed on the upper base 4.

A hole is provided in the lid 3, provided with a pipe 11.

The dust hopper 2 is equipped with nipple valves 12, providing automatic removal of the separated dust.

luooSLl 3 cyclone tubes 7. Due to the action of centrifugal force, dust particles

discarded to the walls of the tubes 7, driven down and poured into the hopper 2. Then, the air flow from the central zone, turning 180 °, enters the cleaned air exhaust pipes 9, while also when the flow turns, additional air purification from impurities takes place. From the tubes 9, the cleaned air enters the cavity 10, from where through the hole in the cover and the pipe 11 to the engine cylinders. When the engine is running due to vacuum in the hopper 2, the valves 12 are in the closed state, and separated dust is collected in them. When the engine stops, the valves open and accumulated dust spills out. Thus, the hopper 2 is automatically cleaned. Depending on the air consumption consumed by the engine on which the air cleaner is installed, the number of cyclones varies, which ensures high efficiency: a high degree of purification up to 90% with a low resistance to air flow - no more than ZOOOP.

The inventive air purifier has a simple design, provides effective cleaning of air from impurities and is well assembled on the rear wall of the car.

The inventive air purifier meets the requirements of industrial applicability and is possible to implement on standard processing equipment using modern technologies.
