Abstract
The utility model relates to a cyclone type primary air filter. A clean air chamber, a dusty air chamber and a dust collecting chamber are arranged in a casing of the utility model. A clean air outlet, a dusty air suction inlet and a dust emission opening are correspondingly arranged. The dusty air chamber is arranged at the outer side of the clean air chamber. The dust collecting chamber is arranged at the outer side of the dusty air chamber. A main filter body which is composed of a cyclone pipe component is arranged in the dusty air chamber. The utility model leads dusty air which is sucked by an engine to rotate with a high speed. Dust is separated to be exhausted under the function of centrifugal force. The cyclone type primary air filter is connected in series with a fine filter of an original engine, and the total filtering efficiency can reach more than 99.5%. The utility model can effectively protect the engine from being worn in early stages, and simultaneously can lead the maintenance period of a papery filter core of the fine filter of the original engine to be extended by ten times or so. The utility model is especially suitable for being used in harsh environments, such as a desert, a mining area, a building site, etc.
Description
The utility model relates to the thick level of a kind of vortex type air-strainer.
The air-strainer that uses on the existing vehicle, general on the concentric circle of fine filtering shell internal layer, be provided with the dihedral vane of a circle annular, also claim strainer, but because the dynamics of separation dirt sand is too little, fly upward at dirt sand, the desert area that visibility is extremely low uses under the rugged environment such as plateau arid surface dust band, mining area, building site, and more dirt sand still enters cylinder, often serious premature wear will appear in more than 3000 kilometer motor of vehicle driving, repair and the economic loss that causes of delaying work very big.
The purpose of this utility model is to design the thick level of a kind of vortex type air-strainer; under the condition that does not change former car air inlet piping; be connected on before the former car refill fine filtering; can after the dirt sand separation more than the φ 10 μ m, discharge housing to the diameter that endangers most motor; can protect motor to avoid premature wear effectively, can prolong the maintenance period of paper filter element simultaneously.
The utility model design proposal: the thick level of a kind of vortex type air-strainer, comprise housing (1), be provided with the chamber that purifies air (2) in the housing (1), close dirt air cavity (3) and dust collection chamber (4), the chamber (2) that purifies air is provided with the air outlet that purifies air (10), the lower end in dust laden air chamber (3) is provided with dust laden air suction port (11), the lower end of dust collection chamber (4) is provided with dust exhaust port (12), dust laden air chamber (3) is arranged on the outside of the chamber that purifies air (2), dust collection chamber (4) is arranged on the outside of dust laden air chamber (3), be provided with main filter body (5) in the dust laden air chamber (3), main filter body (5) is made up of tornadotron assembly (6), tornadotron assembly (6) is by whirlwind outer tube (7), pipe (8) and helical blade (9) constitute in the whirlwind, pipe (8) is inner in the whirlwind communicates with the chamber that purifies air (2), the outer end is positioned at whirlwind outer tube (7) middle part, socket between the pipe (8) in whirlwind outer tube (7) the inner and the whirlwind, the outer end communicates with dust collection chamber (4), is provided with helical blade (9) between the pipe (8) in whirlwind outer tube (7) and the whirlwind.
Purify air chamber (2), dust laden air chamber (3) and dust collection chamber (4) is cylindrical body, and dust laden air chamber (3) are symmetrical set in the both sides of the chamber that purifies air (2), and dust collection chamber (4) is symmetrical set the both sides in dust laden air chamber (3).Or the chamber that purifies air (2), dust laden air chamber (3) and dust collection chamber (4) be rectangular prism, and dust laden air chamber (3) are arranged on a side in the chamber that purifies air (2), and dust collection chamber (4) is arranged on a side in dust laden air chamber (3).And it is inner inboard that the dust laden air suction port (11) of lower end, dust laden air chamber (3) is positioned at whirlwind outer tube (7).
The breathing process of the utility model during by engine operation is inhaled into dust laden air between the inner and outer pipe of tornadotron assembly from suction port, there is blade to lead again because the tornadotron diameter is little, air stream is with regard to high speed rotating, dirt sand is under the forceful action of centrifugal force, the dirt sand of the diameter that endangers most motor more than 10 μ m, be separated to dust collection chamber, discharge housing by dust exhaust port.Cleaned air passes, owing in the intake manifold degree of vacuum is arranged, air-flow anti-180 ° of directions in the whirlwind outer tube are back to that pipe enters the chamber that purifies air in the whirlwind.Enter the fine filtering refill by intake manifold before connecting former car filter again.Thickness after the series connection is filtered total filtering efficiency more than 99.5%; seldom dirt sand is very thin to make the cleaned air passes dust-laden; thereby the appearance dirt burden that has alleviated the fine filtering refill is greatly compared with former car filter; can prolong about 10 times of the maintenance periods of paper filter element, so can effectively protect motor to avoid premature wear.Suit especially under rugged environment such as dirt sand flies upward, visibility is extremely low desert area, plateau arid surface dust band, mining area, building site, to use.
