Description

 The invention relates to the field of engineering, and in particular to large-sized air cleaners for vehicles that have the ability to move in rough terrain and off-road.

 During the operation of the air purifier, the cleaned air passing through the scapular swirler of each separation hole acquires a rotational-translational movement at the outlet of the witness, which ensures the separation of the composite fractions of the pollutant from the air and their entry into a common dust collector. At the same time, cleaned air streams are sent to the intake pipes, and from the latter through the common pipeline to the engine.

 However, great difficulties should be noted if it is necessary to obtain a reliable large-sized monoblock cast housing due to the frequent occurrence of loosening and sinks in the thin, common walls of the separation holes, leading to the appearance of cracks that destroy the common walls, especially when the vehicle is moving over rough terrain and in conditions off-road, with sharp multidirectional shock loads on the air cleaner housing.

 Known air purifier for a vehicle (see ed. Certificate of the USSR 1116203 A, publ. 09/30/1984), containing a rectangular housing with longitudinal rows of separation holes, in each of which on the air inlet side there is a blade flow swirl, as well as attached to the housing a common dust collecting tray with receiving cones (for example, with slots or perforations on the side walls) for cleaned air, with each receiving cone on the top side being placed with a gap inside the outlet section of the separation hole with the image ringing the channel. In said air cleaner, the openings are arranged in rows so as to obtain the largest number of them (in the so-called checkerboard pattern), which ensures an optimum degree of cleaning. During the operation of the air purifier, the cleaned air, passing through the blade swirl of each separation hole, acquires a rotational-translational motion, while the cleaned air enters the inward receiving cones, and from them through a common pipeline to the engine.

 It should be noted that, like an analogue, there are great difficulties in obtaining a reliable air purifier with a large-sized monoblock molded case due to the occurrence of cracks in the thin common walls of the separation holes and their subsequent destruction under the influence of sharp multidirectional shock loads of the air purifier when the vehicle moves in off-road conditions.

 The main task, the solution of which the invention is directed, is to increase the reliability of the large-sized air purifiers for vehicles while maintaining the optimal degree of air purification.

 The fulfillment of this task is achieved due to the rational technical solution associated with the structural design of the corsus of a large-sized air cleaner, while maintaining the number of separation holes in it.

 To obtain the specified technical result in an air purifier for a vehicle, containing a rectangular housing with longitudinal rows of separation holes, in each of which, from the air inlet side, there is a blade flow swirl, as well as a common dust collector attached to the housing with receiving cones for purified air, each the receiving cone from the top side is placed with a gap inside the output section of the separation hole with the formation of an annular channel, in it the body is longitudinal This direction is made composite of at least two parts, while the ends of the parts adjacent to each other are made with alternating opposite protrusions and depressions, and the dust collecting tray is additionally equipped with at least one sealing insert in a form that repeats the shape of the ends and installed under the specified connection, while the sealing insert is made with a horizontal row of through slots located on the sections of the insert so that the slots in the insert and the blade swirls in the separation openings have mutually coinciding directions of swirling air flows.

 Improving the reliability of large-sized air purifiers is achieved due to the possibility of making their housings composed of several parts and the possibility of obtaining parts of the housing by casting without defects while maintaining the optimal degree of air purification.

 The essence of the invention is illustrated by drawings, where figure 1 shows a top view of an air purifier showing one connection of two parts of the housing; figure 2 shows a section along aa of the air purifier in figure 1; in FIG. 3 given place 1 of the air purifier in figure 2; figure 4 is a section along BB of the air purifier in figure 3.

 The vehicle air purifier contains a rectangular molded case 1 with longitudinal rows of separation holes 2, in each of which a blade swirl 3 is placed on the air inlet side, as well as a common dust collector 4 attached to the body (not shown with studs and nuts). In the air cleaner, the separation holes are arranged in rows in a checkerboard pattern so as to obtain the largest number of them (see figure 1). In the dust pan 4 (for example, by welding), receiving cones 5 are fixed (for example, with slots or perforations on the side walls) for purified air, each receiving cone on the apex side being placed with a gap inside the outlet portion of the corresponding separation hole to form an annular channel "a "

 In the air cleaner, the housing 1 in the longitudinal direction is made integral, in the case under consideration, from two parts "b" and "c", while the ends of the parts adjacent to each other are made with alternating opposing protrusions "d" and depressions "e". The dust pan 4 is additionally equipped (in this case) with one sealing insert 6 in a shape that repeats the shape of the ends (see Fig. 4) and is installed under the specified connection. The sealing insert 6 is made with a horizontal row of through slots "f" placed on the sections of the insert so that the slots "f" in the insert and the blade air swirlers 3 in the separation holes 2 have mutually coincident swirling directions of the air flows.

 The execution of the cast housing, for example, from two parts "b" and "c" made it possible to obtain high-quality casting without cracks and loosening in the thin common walls "g" of the separation holes 2, which increased the reliability of the air cleaner when the body is subjected to multidirectional shock loads driving a vehicle in off-road conditions.

 During the operation of the air purifier, the cleaned air, passing through the scapular swirler 3 of each separation hole 2, acquires a rotational-translational motion, while the cleaned air enters through the slots or perforations into the receiving cones, and from them through the common pipe 7 to the engine. At the same time, air flows containing large and small particles of dust, as well as other pollutants are thrown to the walls of the separation holes 2, passing through the annular channel "a" fall into a common dust collection tray 4, and from the latter into the dust suction nozzle 8.

 Due to the presence of slots "f on insert 6, the contaminated air is additionally swirling and prevents the deposition of pollutant fractions on the insert and, in addition, an additional twist intensifies the evacuation of dust from the tray.

 The proposed air purifier is technologically advanced in industrial production and has increased reliability, which allows it to be performed in any oversized dimensions and used in vehicles that can move over rough terrain and in off-road conditions.

 It should be noted that the housing 1 of the air purifier can be made of several parts that are identical in shape and size, which is a know-how.
