Abstract

The utility model discloses a heavy-duty car two-cavity non-filter screen air cleaner, wherein a wind impeller is connected in the duplex inner cavity of a water-proof air inlet hood, a cone-shaped air inlet diversion hood is connected at intervals in the inner cavity of the water-proof air inlet hood under the wind impeller, the lower end of the inner cavity of the water-proof air inlet hood is connected with a dust collection casing, a reverse dust collection hood and the dust collection casing are jointed to form a dust collection cavity on the excircle of an air outlet pipe which is connected with the inner cavity of the dust collection casing, an air inlet orientation positioned on the peripheral surface of the reverse dust collection hood is opposite to an air inlet orientation positioned on the wind impeller, and a dust-exhausting pipe connected on the dust collection casing is communicated with the dust collection cavity. By using the heavy-duty car two-cavity non-filter screen air cleaner, rain and snow droplets and impurities contained in pre-filter air are completely removed through filtration, thereby effectively enhancing the service life of a paper filter element, and the pre-filter air is strongly compressed into an air outlet pipe as the duplex wind impeller is rotated in high speed, thereby improving the flow quantity and smoothness of the outlet air and significantly reducing the resistance of the filtered air when the air enters into an engine.

Description

Heavy-duty car dual chamber non filtering net air filter

(1) technical field:

The utility model relates to air filter for automobile; Be specifically related to a kind of heavy-duty car dual chamber non filtering net air filter.

(2) background technique:

Heavy-duty car air-strainer of the prior art, its structure are to be equipped with filtering machine oil at filtering housing intracavity bottom, are spacing above it successively and are provided with Steel net and papery filter core.During work, treat that air filtering is normally first after filtering machine oil and Steel net coarse filtration, enter in the motor through the smart filter side of papery filter core again and work.When heavy-duty car is worked under abominable wild environment, as sleety weather, though the sleet globule that enters the filter cleaner inner chamber is through coarse filtration, but still have the sleet globule of residual fraction also will filter through papery filter core essence, very easily soak damage filter paper this moment, cause the papery filter core to use and scrap, seriously reduced its working life, increased cost of production.Through the multistage filtering of above-mentioned depuration structure, filtering air inlet flow is little and resistance is big, obviously causes engine consumption to rise and the decline of outputting power ground.

(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 dual chamber non filtering net air filter, is intended to improve papery filter core working life and filtering air inlet flow and reduces intake resistance.

For achieving the above object, the technological scheme of the utility model heavy-duty car dual chamber non filtering net air filter is achieved in that it is a duplex inner chamber at the waterproof airscoop shroud, is rotatably connected with fan blade respectively; Waterproof airscoop shroud inner chamber below described fan blade is spacing and is connected with cone-shaped air inlet fluid dividing cover; Be connected with dust collection shell in described waterproof airscoop shroud inner chamber lower end; On the steam outlet pipe cylindrical that the dust collection shell inner chamber is connected with, ring set is connected with reverse dust shield and the dust collection shell formation dust collection chamber that joins; On reverse dust shield periphery surface, be provided with intake grill towards, the intake grill that is provided with fan blade towards oppositely; Being connected with dust flue on described dust collection shell is communicated with dust collection chamber.

The utility model is by taking said structure, when working as sleety weather, major part contain the sleet globule and impurity proportion little treat air filtering, the powerful air eddy flow that under the effect of duplex fan blade high speed rotating, produces, it by carrying out multistage filtering in the no filter screen filter cleaner of steam outlet pipe input, after filtering, papery filter core essence is supplied engine operation.Wherein fraction contains the sleet globule and the heavy air filtering for the treatment of of impurity, under the effect of strength rotational flow air, enters dust collection chamber and forces discharge rapidly from dust flue by reverse dust shield intake grill.Compare with prior art, eliminated heavy-duty car when the work of abominable sleet sky, treat that the sleet globule and the impurity that contain in the air filtering easily soak damage with the papery filter core of multistage no filter screen filter cleaner, have improved the working life of papery filter core effectively; The duplex fan blade is worked simultaneously and has been improved the charge flow rate for the treatment of air filtering and smooth and easy, with the supporting use of multistage no filter screen filter cleaner, has obviously reduced filtering air inlet resistance.

(5) embodiment:

Fig. 1-shown in Figure 6.This heavy-duty car dual chamber non filtering net air filter, it is the duplex inner chamber at waterproof airscoop shroud 1, is respectively equipped with stationary axle and rotates join (Fig. 1, shown in Figure 5) with the water-sealed bearing that is fixed on the fan blade 2; Waterproof airscoop shroud inner chamber below described fan blade 2 is spacing and is connected with cone-shaped air inlet fluid dividing cover 3; Be connected with dust collection shell in described waterproof airscoop shroud 1 inner chamber lower end; On suction tude 5 cylindricals that the dust collection shell inner chamber is connected with, ring set is connected with skewed reverse dust shield 4 and joins with dust collection shell and constitute dust collection chamber 6 (Fig. 1, shown in Figure 5); On reverse dust shield 4 perimeter ramps, be provided with intake grill towards, the intake grill that is provided with described fan blade 2 towards oppositely (Fig. 2, shown in Figure 4); Being connected with dust flue 7 on described dust collection shell is communicated with dust collection chamber 6.During use, the utility model steam outlet pipe 5 and multistage non filtering net air filter suction port join (shown in Figure 6).When heavy-duty car is worked in the sleet sky, what contain the sleet globule and impurity treats that air filtering is under the powerful suction that engine charge produces, enter its duplex inner chamber respectively by waterproof airscoop shroud suction port, and promote duplex fan blade 2 simultaneously and do high speed rotating and form the powerful air eddy flow, by the inclined-plane shunting of cone-shaped air inlet fluid dividing cover 3, equably the sleet globule and impurity are entered dust collection chamber 6 from dust flue 7 pressures discharge (shown in Figure 1) rapidly by the intake grill strength rotational flow on the reverse dust shield 4.Most of sleet globule and impurity proportion content are little treats air filtering, will treat that by rotating blading wheel 2 the powerful compression of air filtering enters steam outlet pipe 5 through the multistage filtering of no filter screen filter cleaner, by entering engine operation (shown in Figure 6) swimmingly after papery filter core 8 smart the filters.The utility model is the supporting high-power heavy-duty car that is used for 400～500 horsepowers usually.

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 and/or improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.
