Description
Technical Field
The invention belongs to the technical field of automobile engines, and relates to an engine air inlet filter for a large-scale locomotive in a high-dust area.
Background
When the engine is in operation, a large amount of air needs to be sucked, and if the air is not filtered, dust suspended in the air is sucked into the cylinder, so that the abrasion of the piston group and the cylinder is accelerated. Larger particles enter between the piston and the cylinder, causing severe cylinder scuffing, which is particularly severe in dry, sandy working environments. The air intake filter is arranged in front of the carburetor or the air intake pipe, plays a role in filtering dust and sand grains in air and ensures that sufficient and clean air enters the air cylinder.
The engine intake filter is typically a conventional air filter comprised of a filter element and a stationary housing. Air is once filtered through an air filter before entering the engine cylinder, but once filtered through a normal air filter in a high dust area does not reach the air intake cleanliness requirement at all, which accelerates the wear of engine parts. And because the dust concentration is big, the frequency of changing the air cleaner filter core increases, can cause certain cost loss.
Disclosure of Invention

Further, a detachable particle collecting device storage tank is arranged at the corner of the right-angle gas pipeline. Due to the change of direction, large particles fall into the reservoir of the particle collection apparatus with a detachable bottom due to inertia.
Furthermore, the air filter is a cuboid shell, and a detachable filter element is arranged in the middle of the air filter, so that the air filter is convenient to replace.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.
The invention aims to provide an air inlet filter of a large-scale locomotive engine for a high-dust area, which is used for solving the problems in the prior art, improving the cleanliness of air entering a cylinder, improving the safety of the engine and prolonging the service life.
An engine intake filter for a large locomotive in a high-dust area comprises a large-particle filtering device, a sound field aggregation device group and an air filter 10 which are sequentially connected; the large particle filtering device is a cyclone separator 7, and the sound field agglomeration device group comprises at least one sound field agglomeration device; the sound field aggregation device comprises a signal generator, a power amplifier, a loudspeaker and a sound field aggregation chamber which are sequentially connected, wherein the loudspeaker is fixed on one side of the sound field aggregation chamber.
As a preferred embodiment of the invention, the sound field aggregation chamber in the invention is a hollow cylinder or hollow cuboid structure made of stainless steel, and a rigid reflecting plate 5 is arranged on one side of the sound field aggregation chamber away from the loudspeaker and used for reflecting sound waves in a lossless manner to create standing wave sound field conditions in the aggregation chamber.
In a preferred embodiment of the present invention, the cyclone separator 7 has a cylindrical body at the upper part, a spiral air inlet at one side of the cylindrical body, a gas outlet at the upper part of the cylindrical body, a cone at the lower part of the cylindrical body, and a dust outlet at the bottom of the cone.
As a preferred embodiment of the invention, the gas outlet at the upper part of the cyclone separator 7 in the invention is connected with the inlet of the first sonic field agglomeration chamber through a gas pipeline with a turning baffle 6, and the turning baffle 6 is used for separating the sucked coarse particles.

An outlet of the first sound field agglomeration chamber is connected with a second sound field agglomeration chamber through a right-angle gas pipeline, an outlet of the second sound field agglomeration chamber is connected with an air filter 10, and the other end of the air filter 10 is a gas outlet which is led into an engine cylinder.

Examples
As shown in fig. 1, the present embodiment provides an intake filter for a large locomotive engine used in a high dust area, which includes a cyclone separator 7, a deflecting baffle 6, two sound field agglomeration devices, a particle collection device storage tank 8, and an air filter 10. The right side of the cyclone separator 7 is provided with a spiral air inlet, an outlet at the upper part is connected with a first agglomeration chamber 4 through an air pipeline with a folding baffle 6, the first agglomeration chamber 4 is connected with an air pipeline to lead to a second agglomeration chamber 9, the vertical bottom of the air pipeline is provided with a particle collecting device storage tank 8, and an outlet of the second agglomeration chamber 9 is connected with an air filter 10.
Air firstly enters the cylinder of the cyclone separator 7 through the spiral air inlet, and the air flow changes from linear motion to circular motion. Most of the rotating airflow spirally flows downwards from the cylindrical barrel along the wall and flows towards the cone. When the dust-containing gas generates centrifugal force in the rotating process, dust particles with density higher than that of the gas are thrown to the wall of the device. Once the dust particles contact the wall, they lose their inertia and fall down the wall by the momentum of the inlet velocity and downward gravity, and then exit the dust outlet at the bottom. The separated air is discharged from the top exhaust port to enter the sound field agglomeration device, and a part of large particles are filtered again in the gas pipeline leading to the first agglomeration chamber 4 under the action of the impact and centrifugal force of the folding baffle 6, so that the large particles in the separated air are reduced to some extent, as shown in fig. 2.
The sound field aggregation device comprises a signal generator 1, a power amplifier 2, a loudspeaker 3, a sound field aggregation chamber 4 and a reflecting plate 5. The signal generator 1 outputs a sine signal, and the sine signal is processed by the power amplifier 2 to form an alternating current signal with specific frequency and specific amplitude to drive the loudspeaker to work. After frequency debugging and sound pressure level measurement, the first sound field aggregation device is finally set to output sound wave signals of 1500Hz and 130dB for aggregation. And the reflecting plate 5 is used for reflecting sound waves without damage and creating a standing wave sound field condition in the agglomeration chamber. In the sound field agglomeration chamber 4, a sound field is applied to the dust-containing gas, the gas medium generates oscillating motion under the action of sound waves, and the vibration amplitudes of particles with different particle diameters are different due to different inertia. Thus, the large particles and the small particles are moved relatively to each other and collide to be agglomerated, thereby eliminating the existence of the small particles.
After passing through the acoustic field agglomeration chamber 4, the air enters the second acoustic field agglomeration chamber 9 through a right-angle gas pipeline. Part of the particles in the gas pipeline are deposited in the particle collecting device storage tank 8 with the detachable bottom due to the inertia of the change of the direction, so that the deposited particles are convenient to clean. The sound wave signal of 130dB is agglomerated by setting the second acoustic field agglomeration device at 2000Hz, and the frequency is increased in order to agglomerate particles with smaller particle sizes.
Finally, the air passes through the air filter 10, the detachable filter element of the air filter 10 filters the agglomerated particulate matters, compared with the air directly entering from the outside, the content of the particulate matters in the air passing through the air filter 10 is obviously reduced, and finally the air is introduced into an engine cylinder, so that the aims of reducing the abrasion of the cylinder and prolonging the service life are fulfilled.
The specific use and operation steps of the engine intake filter for the high-dust area in the embodiment are as follows:
when a user uses the engine air inlet filter system, the engine air inlet filter system is arranged between an air inlet and a throttle valve, air entering an engine firstly enters a cyclone separator 7 to separate partial large particles under the action of centrifugal force, the air is discharged to a sound field aggregation chamber 4 from an outlet gas pipeline at the upper part of the cyclone separator 6, a folding baffle plate 6 is arranged in the gas pipeline and is used for filtering the large particles sucked up, the first sound field aggregation chamber 4 is aggregated under the action of sound fields of 1500Hz and 130dB sound waves to eliminate small particles, the air is discharged from an outlet of the sound field aggregation chamber 4, partial particles are removed again through the inertial deposition action of the gas pipeline and then enter a second sound field aggregation chamber 9 to be aggregated again, finally, all particles in the air are basically filtered under the action of an air filter 10, and finally the air enters an engine cylinder to be used for the work of the engine.
The embodiment reduces the abrasion of the piston and the cylinder by filtering particulate matters in the air and enabling the air entering the engine cylinder to be less than the particulate matters contained in the air, thereby achieving the purposes of improving the safety and prolonging the service life.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures or equivalent flow transformations made by using the contents of the specification and the drawings, or applied directly or indirectly to other related systems, are included in the scope of the present invention.
