Abstract
Disclosed are a tangential rotational flow pre-filtering device and an air filter assembly. The technical scheme of the tangential rotational flow pre-filtering device includes that the device comprises an open casing and an air inlet arranged on the open casing; an upper partition plate and a lower partition plate are arranged inside the open casing to separate the same; a plurality of rotational flow tubes are arrayed and installed between the upper partition plate and the lower partition plate; an air inlet parallel to the rotational flow tubes is communicated with an inner cavity below the lower partition plate; an inner cavity on the upper partition plate is an air outlet cavity; an opening of the open casing is a connecting surface between the open casing and a casing of the air filter assembly; and an ash discharge opening is arranged on the inner cavity below the lower partition plate. The air filter assembly is characterized in that the tangential rotational flow pre-filtering device is installed on an air inlet of the air filter assembly. By adopting tangential air inflow, the tangential rotational flow pre-filtering device and the air filter assembly can prevent larger dust from entering the inside of the air filter assembly as airflow transversely flows after moving downwards and air is led to the inside of the air filter assembly after separating twice. Besides, installation space is saved as the tangential rotational flow pre-filtering device can be integrated with the air filter assembly.
Description
Technical field
The utility model relates to pre-filter device of tangential swirl and air cleaner assy.
Background technique
Existing air cleaner assy in use need improve the coarse filtration efficient of product, but the normal air filter assembly relies on coarse filtration effect that blade ring filters only about 80%, can't satisfy the vehicle operation of rugged environment etc. far away.The arrangement space of some vehicle is often compact, can not have enough big space to remove to place separately the pre-filter device of an empty filter, adds eddy flow pre-flock device so and then can better save the space in air cleaner assy.
Summary of the invention
In order to improve the air inlet rough filtering effect of air cleaner assy, avoid big dust to enter into air cleaner assy inside, the utility model proposes pre-filter device of tangential swirl and air cleaner assy.
For this reason, the technical solution of the utility model is: the pre-filter device of tangential swirl, comprise uncovered housing, uncovered housing is provided with suction port, it is characterized in that: in uncovered housing, be provided with upper clapboard, lower clapboard separates uncovered housing inner chamber, arrange between upper clapboard, the lower clapboard a plurality of cyclone tubes are installed, suction port axis and cyclone tube parallel axes, suction port is communicated with uncovered housing inner chamber under the lower clapboard, uncovered housing inner chamber on the upper clapboard is an outlet chamber, and uncovered housing uncovered is the junction surface with the housing of air cleaner assy; Be provided with ash-discharge opening with the corresponding housing of uncovered housing inner chamber under the lower clapboard.
Air cleaner assy comprises air cleaner assy, it is characterized in that: the pre-filter device of tangential swirl is installed on the suction port of air cleaner assy; The pre-filter device of tangential swirl, comprise uncovered housing, uncovered housing is provided with suction port, in uncovered housing, be provided with upper clapboard, lower clapboard separates uncovered housing inner chamber, arrange between upper clapboard, the lower clapboard a plurality of cyclone tubes are installed, suction port axis and cyclone tube parallel axes, suction port is communicated with uncovered housing inner chamber under the lower clapboard, uncovered housing inner chamber on the upper clapboard is an outlet chamber, and uncovered housing uncovered is the junction surface with the housing of air cleaner assy; Be provided with ash-discharge opening with the corresponding housing of uncovered housing inner chamber under the lower clapboard.
Beneficial effect: the utlity model has airflow design, and adopt tangential admission, can guarantee that the product charge flow rate satisfies the motor needs, and reduce intake resistance; Charge air flow moves downward, and air-flow becomes lateral flow suddenly to the bottom, carries out the separation of dust and air for the first time, and isolated dust is flowed to ash-discharge opening; Air-flow carries out the separation second time by cyclone tube to air once more afterwards, dust separation can be gone out flow to ash-discharge opening, and clean air leads to air cleaner assy inside, can avoid big dust to enter into air cleaner assy inside.Because the pre-filter device of tangential swirl can be installed in the air cleaner assy, save installing space.
