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: be opened in the venetian blind on the body side wall and get the empty filter of gas from venetian blind, the air outlet of empty filter links to each other with the suction port of motor.Motor is in running, and dust, solid particle and steam a large amount of in the air directly get into empty filter by venetian blind, the working environment of empty filter quite abominable (especially great Northwest dust storm area); Make the working pressure of the filter of having leisure big; Not high through its filtered air cleanliness, cause the wearing and tearing of motor comparatively serious, and; The replacing of empty 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 gets into empty filter is provided.

For solving the problems of the technologies described above; The technological scheme that the present invention adopted is: the air inlet purification device of rear engine; Comprise: vehicle body and the empty filter that is arranged on the airscoop shroud of body tail and matches with motor, described airscoop shroud places the vehicle body top, offers suction port on the side plate of airscoop shroud both sides; Be disposed with air pipe, purifying chamber and downtake from top to bottom between airscoop shroud and the empty filter; The upper end of last air pipe is stretched into airscoop shroud, is positioned at the rear of suction port, and open upper end of air pipe is that suction port is an angle backward on this, and the purifying chamber is stretched into from upper and lower both direction respectively in the lower end of last air pipe and the upper end of downtake; And; Stagger each other in the lower end of last air pipe and the upper end of downtake, the lower end of last air pipe is positioned at the place ahead of the upper end of downtake, and the lower ending opening of downtake is that the air outlet links to each other with the suction port of empty filter; The bottom of purifying chamber is provided with sewage draining exit in the place ahead of downtake.

The air outlet that the said lower ending opening of going up air pipe is promptly gone up air pipe is an angle forward.

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

Suction port on the described airscoop shroud is made up of the inlet hole of row's shutter.

The described concrete structure of going up air pipe comprises: go up corrugated rubber pipe and the last suction tude and the last steam outlet pipe that are separately positioned on corrugated rubber pipe upper and lower end.

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

The invention has the beneficial effects as follows: the present invention is through offering suction port on the side plate of the both sides of the airscoop shroud of overhead; Stopped that well a large amount of dusts, solid particle enter into airscoop shroud; Stretch into the upper end of the last air pipe in the airscoop shroud, recede, stopped that further part dust and the solid particle in the entering airscoop shroud enters into suction tude because its rear and its opening that is positioned at suction port is promptly gone up suction port; Enter into purifying chamber after the one-level filtration through airscoop shroud and last suction tude as cascade filtration; Because stagger each other in the lower end of last air pipe and the upper end of downtake, and the lower end of last air pipe is positioned at the place ahead of the upper end of downtake; Most of dust of entering purifying chamber and solid particle and steam fall into the bottom that is positioned at downtake the place ahead of purifying chamber, from sewage draining exit, discharge.Like this; The air that from downtake, comes out is just relatively cleaner and dry, greatly reduces the working pressure of sky filter, makes that the air that gets into motor is comparatively clean and dry; Thereby reduced the replacing frequency of cleaner cartridge cleaner, prolonged the working life of motor.In addition; The oblique following suction port that suction port on the airscoop shroud adopts shutter, be opened in oblique the last 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 cleaning and dry more of the empty filter of entering; 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.
