Abstract

The utility model relates to an automatic dust removing device which can cause the air cleaner for an automobile to self remove the dust on a filtering core. The automatic dust removing device which can cause the air cleaner for an automobile to self remove the dust on a filtering core is generated on the basis of the original dry-type air cleaner. The automatic dust removing device which can cause the air cleaner for an automobile to self remove the dust on a filtering core is suitable for the air filtering function of various automobiles. The automatic dust removing device which can cause the air cleaner for an automobile to self remove the dust on a filtering core is composed of a rectangle frame, a corrugated cone filtering core, a corrugated partition board, a fixing filtering core bracket, a shutter, and a pipeline. The rectangle frame and the corrugated cone filtering core are used for forming an included angle channel, and pressure air current is generated in the included angle channel. The pressure air current is used for substituting labor to clean the dust of the corrugated cone filtering core, and the corrugated cone filtering core is always kept a clean state.

Description

Automatic aspirating air filter

The utility model is a kind of device that can remove the dust on the filter element, especially a kind of air-strainer that filter core always is maintained in the clean condition.

The filter cleaner that uses is the dry-type air cleaner that regularly cleans dust at present, it must be between the regulation fare register domestic demand manually remove to clean dust on the filter core, if irregularly cleaning, the ratio that will cause mixed gas changes, therefore cause fuel oil to consume above set limit, the motor worker leads decline and causes unnecessary economic loss.

Task of the present utility model provides a kind of automatic dust-collecting type air-strainer, and it not only can filter dust, and can remove the dust on the filter core automatically, makes filter element always remain on clean conditions, makes the constant rate of mixed gas.

The utility model is finished in the following manner, and the left and right side of water tank is installed this filter cleaner in the back upper place of Truck cab or before dolly.A corrugated cone filter core is bonded in the rectangular framework, and the front end of filter core is bonded on the fixed support.The open end of filter core and the afterbody of rectangular frame are bonding, filter core becomes the corrugated of 30 mm wides with folded filter paper, because of cone corrugated filter core open end and framework bonding, undulatory in addition space is exactly the passage of airflow, the a part of process of air-flow that enters the corrugated space enters vaporizer after filter core filters dust, and another part flows through along corrugated channel takes away the dust that is filtered.This air-flow results from travelling speed, speed fastoperation more is also just big more in the stream pressure of corrugated channel, this pressure is when engine operation, less than the required throughput of cylinder, this moment, most air-flow was inhaled into cylinder, when just closing the chock plate of vaporizer when the driver receives oil, the throughput of the required suction of cylinder is less than the throughput of the fluid of the speed of a motor vehicle, the dust that filtered this moment is taken away with this airflow scouring, therefore plays automatic dedusting effect.

The utility model advantage is, do not need regularly with the dust that manually goes to clean on the filter core, and its dedusting automatically, assurance mixed gas constant rate, so it can save fuel consumption more than 10% than existing dry-type air cleaner, and can improve the power of motor.

Below with reference to accompanying drawing the utility model is further described in detail:

Fig. 1 is an automatic dust-collecting type air-strainer key plan of the present utility model;

Fig. 2 is an automatic dust-collecting type air-strainer side view of the present utility model;

Fig. 3 is an automatic dust-collecting type air-strainer right side view of the present utility model;

Fig. 4 is an automatic dust-collecting type air-strainer left side view of the present utility model.

Fig. 1 is a kind of dust-collecting type air-strainer 1 automatically that the utility model provides.It is located at the left and right side of the preceding water tank of the operator cabin back upper place of lorry or dolly, is used for directly receiving the place ahead air-flow that travels.

Fig. 2 is the side view of filter cleaner, the open end of corrugated cone filter core 3 is fixed on 2 li of rectangular frames, corrugated filter core 3 open ends are inboard bonding with corrugated separator plate 4, between corrugated cone filter core 3 outsides and rectangular frame 2, formed the angle passage like this, head-on an air-flow part of coming is finished by the angle passage and is washed away the dust that is filtered, another part enters Carburetor by corrugated cone filter core, 4 li holes of corrugated separator plate and pipeline 7 are fixing, the acute angle of corrugated cone filter core 3 is to be sealed by two bonding forming of undulatory filter paper, fixing with filter core fixed support 5 simultaneously, filter core fixed support 5 is fixing with rectangular frame 2, venetian blind 6 is fixed on the rectangular frame, is used for keeping off the rain or avenging.

Fig. 3 is the right side view of filter cleaner, and the outer side bonds of the inboard of corrugated filter core 3 and corrugated separator plate 4 is simultaneously bonding with rectangular frame 2.

Fig. 4 is the left side view of filter cleaner, establishes venetian blind 6 in rectangular frame 2 the insides, is in closed condition when rain or snow day, and the outside and the rectangular frame 2 of corrugated filter core 3 open ends are bonding, corrugated filter core 3 acute angles and fixedly filter core support 5 is bonding.

Claims
