Abstract

The invention discloses a dustproof air filter. The dustproof air filter has the beneficial effects that firstly, a dust removing function is achieved, when lots of dust exists in filter elements, a movable overturn cover is closed, an electromagnetic valve on an air guiding pipe is started, high-pressure gas in a gas cylinder is pressed into the air filter, the dust attached to the inner filter element and the outer filter element is forced to be discharged out of an air inlet pipe along with the high-pressure gas, and the dust removing effect is achieved; secondly, dust removing can be achieved without dismounting the filter elements, dust removing can be conducted at any time and any place, and operation is convenient and fast; and thirdly, the structure is simple, and manufacturing and installing are convenient.

Description

Dust-collecting air cleaner

Technical field

The present invention relates to the air filter on a kind of automobile, particularly to one with dust-collecting air Cleaner.

Background technology

In order to prevent dust from entering automobile engine, at present, all automobile engines are all connected with setting Being equipped with air filter, wherein the filter element in air filter can stop that dust enters automobile engine In, play the effect of dust in filtered air.But has a problem in that execute at the engineering site stirred up a cloud of dust The Construction traffics such as the excavator of work, loader, will block up full air-filtering at the shortest time dust The filter element of device, air cannot enter automobile engine, the gasoline in automobile engine or bavin unobstructedly Oil can not get the oxygen combustion of abundance, burns insufficient, has both wasted fuel oil, reduced again effect, Also damage electromotor.To this end, workmen have no alternative but must be by the cartridge removal in air filter Get off, install again after cleaning, not only bother, and affect work efficiency.

Summary of the invention

It is an object of the invention to provide a kind of dust-collecting air cleaner carrying dedusting function.

The technical solution used in the present invention is, this dust-collecting air cleaner, including air-filtering The shell of device, air inlet pipe, inner filter core, outer filter element, outer filter element is sheathed on inner filter core, inner filter core Be equipped with filter screen on outer filter element, the appendix that air filter is connected with automobile engine sets work Dynamic upset lid, the rotary shaft of movable upset lid sets control valve, air filter and automobile engine The appendix being connected connects with inner filter core, and gas cylinder is connected with air filter through airway, airway On set electromagnetic valve, airway enters the mouth of pipe of air filter and is positioned at the gas transmission below movable upset lid On tube wall.

Owing to taking technique scheme, therefore the invention have the advantages that one is to carry dedusting Function.When dust is more on the filter element in air filter, movable upset lid can be closed, open Electromagnetic valve on airway, the gases at high pressure in gas cylinder are pressed into rapidly air filter, by with automobile The appendix that electromotor is connected is pressed into inner filter core, then is pressed into outer filter element by inner filter core, forces inside and outside On filter element, the dust of attachment is discharged from air inlet pipe with gases at high pressure, reaches dedusting effect.After dedusting, Unlatching activity upset lid, closes the electromagnetic valve on airway, i.e. recovers original air filter merit Energy.Two is dedusting again of need not being got off by cartridge removal, can dedusting whenever and wherever possible, convenient and swift.Three Being simple in construction, fabrication and installation are convenient.
