Description

The air inlet purification device of rear engine

Technical field

The present invention relates to the air inlet purification device of bus engine, refer more particularly to the air inlet purification device of rear engine.

Background technique

At present, adopt the passenger vehicle of rear-engine, the air inlet air washer of its motor, its structure generally includes: the air filter that is opened in the venetian blind on body side wall and gets gas from venetian blind, the air outlet of air filter is connected with the suction port of motor.Motor is in running, dust, solid particle and steam a large amount of in air directly enter air filter by venetian blind, the working environment of air filter is severe (especially great Northwest dust storm area) quite, make the working pressure of air filter large, not high through its filtered air cleanliness, cause the wearing and tearing of motor comparatively serious, and, the replacing of air filter is very frequent, has increased user cost.

Summary of the invention

Technical problem to be solved by this invention is: the air inlet purification device that a kind of rear engine of the cleanliness that improves the air that enters air filter is provided.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the air inlet purification device of rear engine, comprise: vehicle body and be arranged on the airscoop shroud of body tail and the air filter matched with motor, described airscoop shroud is placed in the vehicle body top, offer suction port on the side plate of airscoop shroud both sides, be disposed with air pipe between airscoop shroud and air filter from top to bottom, purifying chamber and downtake, airscoop shroud is stretched in the upper end of upper air pipe, be positioned at the rear of suction port, above the upper end open of air pipe is that suction port is angle backward, the lower end of upper air pipe and the upper end of downtake respectively from, lower both direction stretches into purifying chamber, and, stagger mutually in the lower end of upper air pipe and the upper end of downtake, the lower end of upper air pipe is positioned at the place ahead of the upper end of downtake, the lower ending opening of downtake is that air outlet is connected with the suction port of air filter, the bottom of purifying chamber is provided with sewage draining exit in the place ahead of downtake.

Air outlet that the lower ending opening of described upper air pipe is gone up air pipe is angle forward.

The upper end open of described downtake is that the suction port of downtake is angle backward.

Suction port on described airscoop shroud consists of the inlet hole of row's shutter.

The concrete structure of described upper air pipe comprises: upper corrugated rubber pipe and the enterprising tracheae and the upper steam outlet pipe that are separately positioned on corrugated rubber pipe upper and lower end.

The concrete structure of described downtake comprises: lower corrugated rubber pipe and the lower inlet duct that is arranged on lower corrugated rubber pipe upper end.

The invention has the beneficial effects as follows: on the side plate of the present invention by the both sides of the airscoop shroud at overhead, offer suction port, stopped well a large amount of dusts, solid particle enters into airscoop shroud, stretch into the upper end of the upper air pipe in airscoop shroud, because it is positioned at the rear of suction port, and its opening is that enterprising gas port recedes, further stopped that the part dust and the solid particle that enter in airscoop shroud enter into enterprising tracheae, enter into the purifying chamber as cascade filtration after the single filter of airscoop shroud and enterprising tracheae, owing to the lower end of upper air pipe and the upper end of downtake mutually staggering, and, the lower end of upper air pipe is positioned at the place ahead of the upper end of downtake, enter the bottom that is positioned at downtake the place ahead that most of dust of purifying chamber and solid particle and steam fall into purifying chamber, from sewage draining exit, discharge.Like this, from downtake, air out is just cleaner and dry, greatly reduces the working pressure of air filter, makes the air that enters motor comparatively clean and dry, thereby reduced the replacing frequency of cleaner cartridge cleaner, extended the working life of motor.In addition, the oblique lower suction port that suction port on airscoop shroud adopts shutter, be opened in the oblique upper air outlet of air pipe lower end and be opened in the downtake upper end has all further stopped part dust and solid particle, makes the air that enters air filter cleaner and dry; In addition, the main body of upper and lower air pipe is respectively upper and lower corrugated rubber pipe, and length, angle can free adjustment, install very convenient.
