Abstract

The utility model discloses a single-cavity oil bath type air filter of a heavy truck. The upper end face of a waterproof air inlet hood is at least provided with a dust exhaust port communicated withthe inner cavity thereof, and the top of the inner cavity is rotatably connected with a fan blade plate; the surface of the fan blade plate is provided with a plurality of cyclone ports; the lower surface of the fan blade plate is fixedly connected with a cone-shaped inlet air diversion hood; the lower end of the inner cavity of the waterproof air inlet hood is connected with a shell; a ring cover on the outer circle connected with the air outlet pipe of the inner cavity of the shell is connected with a steel wire filter screen; and filter oil is arranged at the bottom of the inner cavity ofthe shell under the steel wire filter screen. Strong attraction produced by the air intake of an engine pushes the fan blade plate to rotate in a high speed so as to strongly swirl air to be filteredinto the air outlet pipe, the air intake flow of the multi-stage air filter is increased, the air intake is smooth, and the resistance of filtered air entering the engine is reduced.

Description

Heavy-duty car list chamber oil bath air cleaner

(1) technical field:

The utility model relates to air filter for automobile; Be specifically related to a kind of heavy-duty car list chamber oil bath air cleaner.

(2) background technique:

The air filtering device structure of prior art heavy-duty car air inlet yarn system, its suction port place does not still have anti-impurity or/and the filter of ran-proof and snow-proof.When heavy-duty car is worked under wild environment badly, fly upward or/and the sleet sky as impurity, though enter the filter cleaner inner chamber impurity or/and the sleet globule through filtering, still have most of impurity or/and the sleet globule also will be through the last smart filter of papery filter core, very easily stop up or/and soak the damage filter core this moment.It exists not enough: the one, and the filter cleaner charge flow rate is few and resistance is big, does not satisfy the needs of motor filtering air air feed and reduces its power output; The 2nd, the impurity that contains by the laggard filtering air of going into motor of filter cleaner filtering has influenced the working life of motor or/and the sleet globule.

(3) summary of the invention:

At the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of heavy-duty car list chamber oil bath air cleaner, is intended to improve charge flow rate and the filtering quality that enters motor and reduces its intake resistance.

For achieving the above object, the technological scheme of the utility model heavy-duty car list chamber oil bath air cleaner is to realize like this, it is on the upper-end surface of waterproof airscoop shroud, is provided with a dust exhaust port at least and is communicated with its inner chamber, and the top, chamber is rotatably connected with wind acanthus leaf within it; On described wind acanthus leaf surface, be provided with several whirlwind mouths; Below wind acanthus leaf, be fixed with cone-shaped air inlet fluid dividing cover; Be connected with housing in described waterproof airscoop shroud inner chamber lower end; Be connected with at the housing inner chamber on the cylindrical of steam outlet pipe, ring set is connected with Steel net; Housing intracavity bottom below described Steel net is equipped with filtering machine oil.

The utility model is installed on the suction port place of multi-stage air cleaner by taking said structure during use, treat the impurity that contains in the air filtering or/and the sleet globule carries out filtering to entering filter cleaner effectively, has improved the filtering quality of filtering air; The powerful suction that utilizes engine charge to produce promotes the wind acanthus leaf high speed rotating and will treat that the air filtering strength rotational flow enters steam outlet pipe, increased the charge flow rate of multi-stage air cleaner and smooth and easy, has obviously reduced the resistance that the filtering air enters motor.

Fig. 1 is a partial sectional view of the present utility model;

Fig. 2 is that the A-A of wind acanthus leaf 3 among Fig. 1 is to the part section zoomed-in view;

Fig. 3 be among Fig. 1 B-B to sectional view;

Fig. 4 installs for the utility model user mode and connects sectional view.

(5) embodiment:

Fig. 1-shown in Figure 4.This heavy-duty car list chamber oil bath air cleaner, it is on the upper-end surface of waterproof airscoop shroud 1, is arranged with two dust exhaust ports 2 and is communicated with its inner chamber, on the supporting axle that the top, chamber is connected, is provided with the waterproof sealing bearing and is rotatably connected with wind acanthus leaf 3 within it; On described wind acanthus leaf surface, be provided with several whirlwind mouths (Fig. 1-shown in Figure 3); Below wind acanthus leaf, be fixed with cone-shaped air inlet fluid dividing cover 4; Be connected with housing in described waterproof airscoop shroud 1 inner chamber lower end; Be connected with at the housing inner chamber on the cylindrical of steam outlet pipe 7, ring set is connected with Steel net 5; Housing intracavity bottom below described Steel net is equipped with filtering machine oil 6.During use, the utility model steam outlet pipe 7 usually and two stage filter suction port join (shown in Figure 4).When heavy-duty car is worked under wild environment badly, under the powerful suction that engine charge produces, contain impurity or/and the sleet globule treat air filtering, suction port by waterproof airscoop shroud 1 enters its inner chamber, promote wind acanthus leaf 3 and do high speed rotating formation powerful air eddy flow, this moment fraction than heavy impurity or/and the sleet globule discharge rapidly by the dust exhaust port 2 on the waterproof airscoop shroud, most of slightly light impurity of proportion or/and the sleet globule treat air filtering, the then shunting of the inclined-plane by cone-shaped air inlet fluid dividing cover 4, with impurity or/and the sleet globule by Steel net 5 filter depositions in the filtering machine oil 6 of housing bottom (shown in Figure 1).Through treating under the high-speed rotational effect of air filtering at rotating blading plate 3 that one-level is filtered, connecting tube 8 by the secondary filter cleaner of steam outlet pipe 7 through joining with it enters in the eddy flow chamber of housing bottom sealing, strength rotational flow through cyclone tube 11 passes through its dust discharge end secondary impurity that proportion is heavier or/and the sleet globule, eddy flow enters in the sealing laying dust chamber 12 that eddy flow chamber bottom is provided with, and from dust flue 10 quick eddy flows discharges (shown in Figure 4).Major part after the secondary filtering contain the lighter impurity of proportion or/and the sleet globule treat air filtering, the outlet side by cyclone tube 11 enters in the smart filter chamber of sealing at last, supplies engine operation (shown in Figure 4) swimmingly after 9 three grades of filterings of filter core.The utility model is according to different design needs, can with the supporting use of heavy-duty car multi-stage air cleaner of different model specification.

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not other technical characteristics that the process creative work just can be associated; can also make some modification or/and improve; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.
