Description

one

The invention relates to air purification devices and can be applied in engine building.

Known designs of multi-cyclone air cleaners, containing 5 dust-collecting chamber, located in it the riveted cyclones and ejection pipe 1.

To increase the rigidity of air cleaning in the axial direction of the inner of the dust chamber, between its rollers, spacers are placed.

The disadvantages of such structures are the complexity caused by the use of a large number of different types of parts, the lack of detail, due to the presence of places of possible air leaks from the outside at the junction points of the dews, increased 20 meters capacity due to the need to provide the required stiffness of the spacers and covers, large weight.

A vortex air cleaner is known, comprising a housing, an upper 25 valve, separating elements placed in its openings with flow swirlers, a lower cover placed in its openings coaxially with the separating elements

purified gas water and a pipe to remove trapped dust 2.

A disadvantage of the known construction is low rigidity in the axial direction, which, when using the device in internal combustion engines, leads to a decrease in the service life of the air cleaner.

The purpose of the invention is to increase the durability of the device due to the mechanical strength in the axial direction and to prevent installation and centering of the separation elements.

The goal is achieved by the fact that the vortex air cleaner is equipped with support ribs located between the lower ends of the separation elements and the bottom.

In addition, in order to simplify installation and centering of the separation elements, the body is made of two parts — the lower and upper, having an annular groove and a protrusion in the place of their connection, respectively, the upper part of the body is made in one piece and the upper lid and the separation element and and the bottom - in one piece with the bottom cover, pipes for removing the cleaned gas and supporting ribs.

FIG. 1 shows the air cleaner, the cut; in fig. 2 shows section A-A in FIG. one.

The air cleaner comprises a housing 1, an upper lid 2, a lower lid 3, separation elements 4 with swirlers 5, nozzles 6 for clean water from purified gas, a nozzle 7 for evacuating trapped dust 7, support ribs 8.

The ribs 8 form with the lower ends of the separation elements a rigid connection when subjected to compressive forces in the axial direction, arising during assembly, installation on the tractor, transportation and storage of air cleaners.

The upper part of the housing 1 is made in one piece with the lid 2 and the separating elements 4. The lower part of the housing is made in one piece with the lid 3, the nozzles 6 and the ribs 8. At the junction 9 there is a groove on the upper part and a protrusion on the lower part.

The device works as follows.

Under the action of a vacuum created by an engine (not shown), the polluted air enters the separation elements 4 to the swirlers 5, where it acquires a rotary motion. In this case, the dust particles under the action of centrifugal forces are thrown to the walls and fall into the lower part of the housing 1, from where they are removed through the nozzle 7.

The ribs 8 contribute to a better distribution of the ejected air flows in the volume of chamber 1, as a result of which the quality of the individual cyclones removed from the nozzle 7 is improved. The cleaned air through the nozzles 6 is directed to the engine intake manifold.

Such an air purifier design enhances its reliability by reducing axial loads perceived by the side walls, eliminates the need for special spacers, and ensures that the dust-collecting chamber is made of two plastic parts produced by casting on high-performance injection molding machines. The required rigidity in the manufacture of plastic is provided due to the tubular shape of the separation elements 4 and the relatively low height of the ribs 8. At the same time, the number of types of parts in the air cleaner. reduces to three (the lower part of the housing 1, the upper part of the housing 1, swirlers 5), which significantly increases the reliability of the device, simplifies its design and contributes to weight reduction.

The presence of a groove and a protrusion at the junction of the housing parts improves the precision of the air cleaner and simplifies the process of its assembly. five
