Description

The utility model relates to mechanical engineering, in particular to air purification systems of a transport internal combustion engine, namely, to its elements of preliminary air purification. This device can be used in other technical systems that require such a function.

Known multi-cyclone air purifier containing a housing, separation elements, blade flow swirls, a discharge pipe, a dust hopper, while the housing is made integral, made of two identical half forms, consisting of two parallel identical surfaces and connecting their side surface and connected with screws, input the holes are arranged in rows, forming two rectangles placed symmetrically at the top in each of the half-forms, scapular flow swirls are placed horizontally rows and are fixed on two mounting panels, each of which is placed in the body half-mold parallel to its lateral surface, while each of the blade swirlers is made in the form of a cyclone tube made in the form of a truncated cone, in which a truncated cone with rigid blades is placed, below in the center of the housing there is a pipe for removing purified air, the side surfaces of each of the half-forms of the housing are narrowed at the bottom, forming a dust collector, and an automatic machine is inserted into each dust collector dust collecting valve (patent RU No. 127825 U1, IPC F02M 35/02 (2006.01), publ. 06/10/2012).

The closest to the claimed technical solution in terms of the set of essential features and the technical result achieved is a multi-cyclone air purifier for an internal combustion engine containing parallel baffles, one of which has cleaned air exhaust pipes with flow swirls and which is closed by an air duct that communicates with the engine intake system through a discharge pipe, and cyclone tubes are installed in the other, and which is closed by a lid, forming with At the same time, the housing is formed by connecting along the axis of the outlet pipe two identical parts of the half-shells, in which vertically arranged partitions are made with openings and into which the pipes of the cleaned air are installed with flow swirls, and the walls of the half-shell when connected to the partitions form a discharge air duct ending the outlet pipe, and from the ends of the half-housing are closed with covers, between which and the half-shells are septa with holes in which the These are cyclone tubes and covers, with partitions forming dust collecting bins, and between the partitions on the walls of the half-bodies there are windows for air inlet (patent RU No. 116913 U1, IPC F02M 35/02 (2006.01), publ. 06/10/2012).

Existing designs of air pre-treatment elements have disadvantages associated not only with an increase in the local resistance of the device itself, but also with a decrease in the efficiency of air purification. The increase in resistance from the device affects the decrease in the performance of the internal combustion engine and, as a consequence, the deterioration of the vehicle.

The task was set to increase the efficiency of the air pre-treatment element by creating an original design solution.

The problem is solved in that in a multicyclone air cleaner for an internal combustion engine, comprising a housing in which partitions are arranged, pipe boards with cyclones installed therein, an air intake, an exhaust air outlet ending with an outlet pipe, a dust collecting hopper equipped with nipple valves, and partitions in the housing are installed parallel to the axes of the cyclones with the formation of compartments, cyclones are placed in compartments in a checkerboard pattern in two groups, while the dust collecting hopper is equipped with guides made with an inclination towards the nipple valves and fixed on one side to the hopper, and on the other hand to the stiffener installed in its central part. In the particular case of the execution of the group of cyclones in the compartments form a channel-gallery, and at the entrance to the compartments - an air wedge.

The claimed technical solution is illustrated by the following drawings:

FIG. 1 - multicyclone air purifier for an internal combustion engine, a longitudinal section along the axes of the cyclones;

FIG. 2 - the same, a cut across the axes of the cyclones.

The air purifier comprises a housing 1 with two tube sheets 2, between which cyclones 3 are mounted hermetically in connection with the tube sheets 2, which in turn consist of an axial flow swirler 4, a cyclone tube 5 and a purified air exhaust pipe 6. To ensure the rigidity of the structure formed by the pipe boards 2, cyclones 3 and the housing 1, partitions 7 are provided between the pipe boards 2. Partitions 7 installed in the housing parallel to the axes of the cyclones 3 simultaneously perform the function of dividing air into the air cleaner compartments 8 with the aim of uniformly loading all cyclones. When installing the air purifier and its further operation, the arrangement of the axes of the cyclones 3 is horizontal. In the organized compartments 8 of the air purifier, the cyclones 3 are staggered in two groups so that a gallery channel 9 is formed between them for passage and subsequent maximum uniform distribution of the flow between cyclones 3, while at the entrance to the compartment the arrangement of cyclones in groups is wedge-shaped to give the flow to a wedge-shaped turn in order to reduce resistance when the flow passes through the channel-gallery 9. From the side of the cyclone tube 5, the dust collector is sealed on the tube board 2 nker 10 for collecting and removing the separated particles, which has a stiffening rib 11 and inclined guides 12 for moving the separated particles to the nipple valves 13 located on the nozzles 14 of the hopper 10. The guides 12 are fixed on one side to the hopper 10, and on the other hand to rib 11 installed in its central part. From the side of the tubes 6 of the cleaned air outlet, the exhaust duct 15 is sealed to collect cleaned air to collect the cleaned air, having a fin for the structural rigidity and an outlet pipe 16 for draining the cleaned air into the air filter of the air purification system. To protect against direct ingress of precipitation in the form of rain in summer and snow in winter, inside the air cleaner between the tube plates 2, in its upper part, a protective cover 17 is provided with a grill 18, which is an air intake 19. The grille 18 is designed to prevent foreign objects from flowing into the air cleaner through the inlet window 20. To drain the water and spill out the dust that got into the air cleaner, there are drain holes 21 in the lower part of its body.

The air purifier operates as follows.

When the engine is running, dusty air is drawn in through the inlet window 20 with the grill 18, then it is distributed in the compartments 8 of the air cleaner. In the space between the partitions 7, the flow passes through the gallery channel 9 and is evenly distributed between the cyclones 3. Then, the flow enters the swirlers of the flow 4 and receives rotational screw motion in the cyclone tubes 5. Due to the action of centrifugal force, dust particles are thrown to the walls and are driven into a dust collector hopper 10. Further, the air flow from the central zone, turning 180 °, enters the cleaned air exhaust pipes 6. At the same time, when the flow turns, additional air purification from impurities also occurs. From the tubes 6, the cleaned air enters the air outlet 15 and then to the air filter. When the engine is operating due to rarefaction in the hopper 10, the nipple valves 13 are in a closed state and separated particles are collected in them. When the engine stops, the nipple valves 13 open, and the separated particles spill out, so the hopper 10 is automatically cleaned.

The air purifier according to the claimed technical solution has a sufficiently high degree of air purification from particles suspended in the air, the design is simple, it can be mounted on a car, for example, on the rear wall of the car cab. The design of the air purifier is constructed in such a way that the number of its compartments provides an acceptable resistance at a given maximum air flow, with an increase in this flow, the number of compartments can be increased for the condition of constant resistance.

The claimed technical solution allows to increase work efficiency, reduce the resistance of the air cleaner, improve the main indicators of the internal combustion engine and the characteristics of the vehicle as a whole, operate a car with this air cleaner in dusty conditions, increase the resource and service interval for changing the main filter element of the car air purification system.

The technical solution meets the requirements of industrial applicability and is possible for implementation on standard processing equipment.
