Description
Technical Field
The invention relates to the technical field of engine air inlet filtration, in particular to a front separator and a multistage separator of an engine air inlet filter.
Background
The air filter is an important part for preventing impurities from entering an air inlet system of an engine, the air filter is difficult to normally operate in a severe environment, a vehicle air inlet system using a common filter screen is easy to generate pipeline blockage, a sufficient amount of clean air cannot enter a cylinder, if solid particles enter the engine, the piston and the cylinder are worn, so that the engine is damaged, and the personal safety is influenced.
Air filters commonly used in the market generally adopt filter screens to filter, sand dust and water vapor can be detained in the filter and can not be discharged, the inside of a pipeline is easy to be blocked, the filter screens are required to be replaced frequently and manually, and the operation is complex and the service lives of the filter and an engine are influenced.
The air filter commonly used in the market generally adopts a filter screen filter element, a pleated paper filter element and a non-woven fabric filter element;
in the prior art, in order to prolong the service lives of an engine and a filter screen, the air is usually prefiltered once before entering the filter screen of an air inlet channel of the engine, so that the dust amount entering the filter screen in unit time is reduced, and the interval time for replacing the filter screen is prolonged.
Currently, prefiltering is generally performed by filtration with filter paper or nonwoven fabric.
When adopting filter paper to filter, the paper filter core is moist when rain and snow gets into the filter, and filter paper is easy to block up, reduces life, is broken down even and is scrapped, and the filter core forms the fold through fiber paper annular folding to improve filtering efficiency, leads to its resistance that admits air great. And the waste cannot be automatically discharged, and the problem of blockage and cleaning is still caused by the fact that the solid-liquid waste cannot be timely discharged.
When the non-woven filter element is adopted, the air flow is small due to poor gas passing property of the non-woven fabric, so that the blockage of a pipeline is aggravated, waste cannot be automatically discharged, and the problems of timely cleaning and the like cannot be solved.
CN201420444104.7 also discloses a large flow drain valve of an air cleaner for an automobile, an air cleaner and an automobile. The one-way valve with the rubber pad can prevent external dust and water from entering, and ensure that large sand and stone particles and accumulated water in the air filter are discharged, so that the working performance of the air filter is improved, and the service life of the filter element is prolonged. Although the one-way valve is used for discharging solid and liquid wastes, the aggregation process is not centralized, the efficiency is low, the rate is low, the discharged materials are not easy to aggregate to the discharge holes, and the working requirement is difficult to reach when the liquid is lacking.
In summary, the existing prefilter has the problems that the waste cannot be automatically discharged and blockage still needs to be cleaned, or solid-liquid waste can be discharged, but the aggregation process is not concentrated, the efficiency is low, the speed is low, and the discharged materials are not easy to aggregate to the discharge holes.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a front separator of an engine air inlet filter, which comprises a round separation bin 1 and a filter air inlet pipe 2 tangentially connected to the separation bin 1;
the bottom of the separation bin 1 is provided with an opening for the penetration of the engine air inlet pipe 3, and the separation bin 1 and the engine air inlet pipe 3 are coaxially arranged;
The engine air inlet pipe 3, the separation bin 1 and the filter air inlet pipe 2 are communicated with each other, so that gas can flow along the filter air inlet pipe 2, the separation bin 1 and the engine air inlet pipe 3 in sequence under the suction force generated by the engine;
the separation bin 1 is used for carrying out cyclone separation on tangential input airflow, and the bottom of the separation bin 1 is also provided with a one-way valve 4 for discharging separated solid-liquid waste.
The front separator is arranged on an engine air inlet pipe 3, the engine air inlet pipe 3 is inserted into a separation bin 1 and is close to the top of the separation bin 1, and the specific working process is as follows:
Depending on the suction force generated by the operation of an engine, outside air can tangentially enter the separation bin 1 through the filter air inlet pipe 2, the circular separation bin 1 can enable gas entering the separation bin to generate rotational flow, under the action of centrifugal force, gravity shearing friction force and other conditions, solid, liquid and gas receive different centrifugal accelerations due to the existence of density difference, so that layered rotary flow is gradually formed, the solid and the liquid sink to be close to the inner wall surface and the bottom of the separation bin 1, the one-way valve 4 is opened by the air pressure in the separation bin 1, the solid and the liquid are discharged out of the separation bin 1 through the one-way valve 4, the air floats upwards to be close to the central position and the upper part of the separation bin 1, and clean air enters the engine air inlet pipe 3 provided with a filter element and other filter devices for secondary filtration.
In summary, compared with the traditional engine air inlet filter device, the front separator only adopts the filter screen to filter the solid-liquid-gas mixture in the air in the traditional process, and the waste remains in the filter, so that the front separator is extremely easy to cause blockage in sand dust and rain and snow weather and needs frequent manual replacement and maintenance. The cyclone separation technology adopted by the invention utilizes the centrifugal force and gravity generated by the gas cyclone in the separator to effectively and rapidly gather the waste at the discharge port, and the waste is discharged through the one-way valve 4, so that the process is simple and effective, the dirty air before entering the engine air inlet filter screen is effectively treated, the problems of moisture and blockage of the engine air inlet system filter screen are solved, the device is simple and convenient, the installation applicability is high, and the device is obviously improved for vehicles working in severe weather such as sand dust, rain and snow.
And the speed of the tangential entry of the gas into the separation chamber 1 is generated based on the suction force generated by the operation of the engine, without the need for an additional blowing mechanism.
Normally, the intake pressure of natural aspiration is about 30kpa when the engine is in operation, so that a sufficiently strong negative pressure can be formed in the separation chamber 1 to support the generation of swirl flow.
