The invention discloses an air inlet
system of a double-section crawler-type all-
terrain armored car. A plurality of small-
diameter cyclone separators are arranged in parallel to form an air inlet pre-filtering element, after air mixed with dust and particulate matters enters a
pipe, strong rotating air flow can be formed under the action of a spiral
air chamber, and according to a
centripetal force formula, under the condition that the entering speed is not changed, the larger the
mass of an object is, the larger the
centripetal force is, and the larger the
centrifugal force is, so that the dust and the particulate matters with larger
mass can be thrown to an outlet in the periphery of the
pipe wall, leave the
pipe, enter a connecting cavity and then enter a dust
discharge pipe, the adhesion amount of a filter screen of an
air filter in unit time is reduced, and the service life of the filter screen is prolonged; and a radiator
assembly adopts a high negative pressure fan, a wind scooper is connected with an air prefilter and the
air filter, the particles and the dust discharged by the air prefilter and the
air filter are automatically discharged through high negative pressure, the
automation degree is high, and manual regular cleaning is not needed.
