Abstract
An air filtration device is used in purification of combustion-supporting air in an internal-combustion engine under a high-dust environment, or purification of air absorbed into an air compressor, and overcomes defects that a filter core needs to be frequently replaced and cylinder parts are easily worn existed in use of an existing purification device under the severe environment. The air filtration device comprises a casing, a machine external air inlet arranged on the casing, an absorbing machine internal air outlet arranged on the casing, an air filter arranged in the casing and formed by a filter core, and a cyclone de-dust device comprising a wind inlet, a rotating wind channel, a dust falling cone, a dust collecting container and a wind discharging opening. The air purification wind discharging opening of the cyclone de-duct device is connected to an air inlet of the air filter. The air filtration device has the advantages of lightening work burden of the air filter, prolonging service life of the filter core, greatly reducing dust entering air cylinders, lowering wear of the air cylinders, and being applied to various diesel engines, gasoline engines and air compressors.
Description
Technical field
The invention belongs to mechanical field, be specifically related to air cleaning unit.
Background technique
Purify the air-strainer that gets into the internal-combustion engine combustion-supporting air and get into the air compressor compression cylinder on the existing internal-combustion engine, by shell, air outlet slit, cased filter core are formed in machine outer air import on the shell and the inhalation machine.This kind filter cleaner can satisfy the purification requirement that generally sucks the combustion-supporting air in the internal-combustion engine.But for long-term or operate mainly in the internal-combustion engine in the big or wind sand environment of dust; Use the air-strainer of existing structure; Then need the frequent change filter core, reduce and quicken the component abrasion in the cylinder of internal-combustion engine otherwise can cause filter cleaner ventilation freely not reach the air purification degree.
Summary of the invention
The purpose of this invention is to provide a kind of air filtration unit; The internal-combustion engine combustion-supporting air that is used under the high dust atmosphere purifies; Or suck Air Compressor and purify, overcome existing purifier and use the need frequent change filter core that in rugged environment, exists and be prone to deficiency that cylinder part is worn.
Air-strainer that air filtration unit of the present invention is made up of the filter core in air outlet slit, the shell in the machine outer air suction port and the inhalation machine that comprise on shell, the shell and the cyclone dust collector that comprise intake grill, rotation air channel, depositing dust cone, dust collecting container, exhaust port are formed, and the exhaust port that purifies air of cyclone dust collector is connected on the suction port of air-strainer.
Air filtering process of the present invention is: dust-contained airflow sucks cyclone dust collector, and air-flow changes circular movement into by straight line motion, and spiral motion from top to bottom is to the cone bottom.Under centrifugal action, heavy solid particle is centrifugal to be fallen in the dust collecting container of cone lower end to touching the barrel deceleration.Remove the air of larger particles and majority of particles, get into air-strainer,, get into cylinder more further by filter element filtering through the deduster exhaust port.
Good effect of the present invention is: alleviated the work load of air-strainer, prolonged the working life of filter core, reduced the dust that gets into cylinder significantly, reduced the wearing and tearing of cylinder.Be applicable to all kinds of diesel engines, petrol engine, air compressor.
Description of drawings
Accompanying drawing is overall structure figure of the present invention.
Embodiment
The air-strainer of being made up of air outlet slit 1c, shell and cased filter core in machine outer air import 1j, the inhalation machine 1 and comprise that the cyclone dust collector 2 of intake grill 2j, rotation air channel, depositing dust cone, exhaust port 2p, dust collecting container 2r form, the exhaust port 2p that purifies air of cyclone dust collector is connected on the air-strainer air intlet 1j.
