Abstract

The utility model discloses a heavy-duty vehicle heavy-duty car high-power air filter, which comprises a filter body and an air inlet casing which is connected with the filter body, wherein the upper end of a cyclone tube which is arranged in the inner cavity of the air inlet casing is communicated with the inner cavity of the filter body, a forward cyclone disc is rotatably and circularly meshed and connected on the outer circle of the lower end of the cyclone tube arranged in the inner cavity of the air inlet casing arranged on the lower portion of the air inlet pipe, which is circularly meshed and connected with a backward cyclone disc which is fixedly connected in the inner cavity of the air inlet casing, and the directions of an air inlet and an air outlet which are arranged on the forward cyclone disc and the backward cyclone disc are different, and a dust-containing casing is connected at the bottom of the inner cavity of the air inlet casing to communicate with a dust tube. An air inlet and an air outlet which are arranged on the forward cyclone tube and the backward cyclone tube are used to produce high-power cyclone air with small resistance to smoothly, quickly and completely discharge dust impurities contained in filter air through the inner cavity of the dust-containing casing. The heavy-duty vehicle heavy-duty car high-power air filter eliminates early-stage block of filter cores, reduces air filter resistance, has simple structure, effectively improves air filtering quality and output power of the generator, and obviously lowers the production cost.

Description

Heavy-duty car dry-type strength air filter

(1) technical field:

The utility model relates to the automobile air filter; Be specifically related to a kind of heavy-duty car dry-type strength air filter.

(2) background technology:

Heavy-duty car dry-type air cleaner of the prior art, its structure are square air intake and the dust discharge housing inner chambers that is provided with below filter housing, are connected with many and are the cyclone pipe that spacing is arranged.When treating that air filtering filters when entering engine operation through filter housing by the square casing inner chamber, the dust impurity that contains in the filtered air then enters the square casing intracavity bottom by many cyclone pipes to be difficult to all discharge rapidly.Exist not enough: the one, the dust impurity that is difficult to discharge stockpiles the early stage obstruction that causes filter core at the housing intracavity bottom, has had a strong impact on the air inlet quality that engine air filters; The 2nd, the square air intake and the dust discharge housing inner chamber filtering air drag of many cyclone pipe arrangements are big, have influenced the power output of engine; The 3rd, complex structure has increased production cost.

(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 dry-type strength air filter, is intended to improve engine air filtering quality and power output and reduces production costs.

For achieving the above object, the technical scheme of the utility model heavy-duty car dry-type strength air filter is achieved in that and mainly comprises filter housing and coupled inlet shell; The tornadotron upper end that described inlet shell inner chamber is provided with is communicated with the filter housing inner chamber; In the bottom of described tornadotron, be fixed on the reverse eddy flow tray bearing support of inlet shell inner chamber, be rotatably connected with the forward eddy flow tray; One end endoporus of described forward eddy flow tray links to each other with tornadotron lower end cylindrical ring set, and its other end endoporus joins with reverse eddy flow tray cylindrical ring set; Be provided with air inlet on the forward eddy flow tray and on reverse eddy flow tray, be provided with the direction of air outlet reverse; Inlet shell intracavity bottom below described reverse eddy flow tray air outlet is provided with and holds the dirt housing; Described appearance dirt housing lower end is communicated with the dust flue that is connected in the inlet shell bottom.

The utility model is by taking said structure, during work, enter the air filtering for the treatment of of inlet shell inner chamber, the air inlet that is rotatably connected with the forward eddy flow tray by its inner chamber produces the little strength rotational flow air of resistance with the air outlet that is fixed with reverse eddy flow tray, makes the dust impurity for the treatment of to contain in the air filtering swimmingly by holding whole rapid discharges of dirt housing inner chamber.Compare with prior art, eliminated the early stage obstruction of filter core and reduced air-filtering resistance and simple in structure, improved the quality and the power output of engine air filtering effectively and reduced production cost significantly.

(5) specific embodiment:

Fig. 1-shown in Figure 6.This heavy-duty car dry-type strength air filter mainly comprises circular filter housing and coupled circular inlet shell; Tornadotron 2 upper ends that described inlet shell inner chamber is provided with are communicated with the filter housing inner chamber; In the bottom of described tornadotron 2, be fixed on reverse eddy flow tray 4 bearing supports of inlet shell inner chamber, be provided with the dust seal bearing and be rotatably connected with forward eddy flow tray 3; One end endoporus of described forward eddy flow tray 3 links to each other with tornadotron 2 lower end cylindrical ring sets, and its other end endoporus is with reverse eddy flow tray 4 cylindrical ring sets join (Fig. 1-shown in Figure 2); At the direction that is provided with several air inlets 9 on the forward eddy flow tray 3 and on reverse eddy flow tray 4, is provided with several air outlets 10 oppositely (Fig. 4, shown in Figure 6).Inlet shell intracavity bottom below described reverse eddy flow tray air outlet 10 is provided with the appearance dirt housing 5 of cone shape; Described appearance dirt housing lower end is communicated with the dust flue 6 that is connected in the inlet shell bottom.During work, the air filtering for the treatment of that contains dust impurity enters the inlet shell inner chamber through blast pipe 7, when the air inlet 9 by the forward eddy flow tray, produce eddy flow thrust and promote its forward eddy flow tray 3 around the cylindrical of tornadotron 2 and reverse eddy flow tray 4 cycle rotation (Fig. 1 ceaselessly, shown in Figure 2), make the little inlet shell inner chamber that air filtering enters between forward eddy flow tray 3 and the reverse eddy flow tray 4 for the treatment of of resistance form powerful air eddy flow (shown in Figure 1), under the effect of strength rotational flow air, the air filtering for the treatment of that contains dust impurity enters cone shape appearance dirt housing 5 inner chambers through the air outlet 10 quick eddy flows of reverse eddy flow tray, at this moment, proportion is heavier treats the dust impurity that contains in the air filtering, under the effect of strength rotational flow air, rotate to its bottom along the appearance dirt housing 5 inner chamber inclined-planes of its cone shape rapidly and discharge outside the inlet shell by dust flue 6.Most of proportion is lighter treats that air filtering enters to filter in the filter core 1 in the filter housing by tornadotron 2 bottoms and enters engine operation (Fig. 1-shown in Figure 6) swimmingly through discharge pipe 8 under the suction of engine.

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 characterictic that the process creative work just can be associated; can also make some modification and/or improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.
