Abstract

The utility model discloses a monomeric whirl air filter of a heavy-duty truck, wherein the upper end of a shell is provided with an air inlet pipe (1) which is communicated with a whirl cavity (2) arranged in the shell; the whirl cavity is provided with dust-exhausting ends of a plurality of whirl pipes (3), and the dust-exhausting ends are communicated with a dust-exhausting cavity (4) arranged at the bottom of the shell; the shell of the dust-exhausting cavity is provided with a dust-exhausting port (6); and the air outlet ends of the whirl pipes are communicated with an inner cavity of an air outlet pipe (5) arranged at the upper part in the shell. When in use, the monomeric whirl air filter is connected with the heavy-duty truck filter to be modified in series, utilizes the strong attractive force generated by conducting air suction on an engine, leads the air to be filtered entering the whirl cavity to generate strong air whirl by a whirl pipe, so as to carry out primary crude filtering on impurities in the air to be filtered or/and rain-snow water beads, thus prolonging the cleaning and maintaining time and service life of secondary refining filtrating paper filter core, effectively reducing the use cost of driving and obviously improving the quality of filtered air of the engine.

Description

Heavy-duty car monomer rotational flow air filter

(1) technical field: the utility model relates to air filter for automobile; Be specifically related to a kind of heavy-duty car monomer rotational flow air filter.

(2) background technique: in the prior art, needing the air cleaner cartridge on the repacking heavy-duty car is the papery structure, and its suction port place does not have the filter of anti-impurity or 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 papery filter core needs frequent disassembly, cleaning to safeguard or replacing is installed, and has increased the user cost of driving; The 2nd, as untimely clean and maintenance or install to change the papery filter core, enter the filtering air of motor by the filter core of its obstruction or damage, contain more impurity or/and the sleet globule, influenced the quality of motor filtering air.

(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 monomer rotational flow air filter, is intended to reduce the driving user cost and improves the quality that enters motor filtering air.

For achieving the above object, the technological scheme of the utility model heavy-duty car monomer rotational flow air filter is achieved in that the suction tude that the housing upper end is provided with, and is communicated with the eddy flow chamber that is provided with in its housing; Described eddy flow chamber is provided with the dust discharge end of some cyclone tubes, is communicated with the dust discharge chamber that housing bottom is provided with; The housing in dust discharge chamber is provided with dust exhaust port; The outlet side of described cyclone tube, the steam outlet pipe inner chamber that is provided with top in the housing is communicated with.

The utility model is by taking said structure, be connected in series with needing the papery filter core filter cleaner on the repacking heavy-duty car during use, the powerful suction that utilizes engine charge to produce, make the air filtering for the treatment of that enters in the eddy flow chamber, powerful air eddy flow by the cyclone tube generation, with the impurity treating to contain in the air filtering or/and the sleet globule carries out the one-level coarse filtration, clean and maintenance time and its working life of secondary micronic paper matter filter core have been prolonged, effectively reduce the user cost of driving, obviously improved the quality that enters motor filtering air.

(4) description of drawings: Fig. 1 is a sectional view of the present utility model;

Fig. 2 is the left pseudosection of Fig. 1.

(5) embodiment: Fig. 1-Fig. 2 shows.This heavy-duty car monomer rotational flow air filter is the suction tude 1 that the housing upper end is provided with, and is communicated with the eddy flow chamber 2 that is provided with in its housing; Described eddy flow chamber is provided with the dust discharge end of some cyclone tubes 3, is communicated with the dust discharge chamber 4 that housing bottom is provided with; The housing in dust discharge chamber is provided with dust exhaust port 6; The outlet side of described cyclone tube 3, steam outlet pipe 5 inner chambers that are provided with top in the housing are communicated with.During use, steam outlet pipe 5 of the present utility model, the papery filter core filter cleaner suction port of reequiping on the heavy-duty car with needs links to each other.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, enter the eddy flow chamber 2 that is provided with in the housing by suction tude 1, powerful air eddy flow through cyclone tube 3 generations, by its dust discharge end with fraction than heavy impurity or/and sleet globule eddy flow enters in the dust discharge chamber 4, and discharge from dust exhaust port 6 eddy flows fast.After the one-level coarse filtration major part contain light specific gravity impurity treat air filtering, outlet side eddy flow by cyclone tube 3 enters steam outlet pipe 5 inner chambers, enter the smart filter of secondary papery filter core filter cleaner on the heavy-duty car through connecting tube, supply engine operation (among Fig. 1, Fig. 2 shown in the direction of arrow) swimmingly.

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.
