Abstract

The utility model discloses a heavy automobile dry air cleaner. The top of an inner cavity formed by a lower casing (6) and an upper casing (2) which are aligned and connected is fixedly connected with a vortex sleeve (4); an air intake pipe (3) is arranged at the upper casing (2) at the outer circle of the vortex sleeve (4); the inner cavity of the vortex sleeve (4) is connected with a filter core (5) in interval loop; the upper end of the inner cavity of the filter core (5) is communicated with an air output pipe (1) at the top of the inner cavity of the upper casing (2); a dust guard (7) is arranged between the lower end of the filter core (5) and the bottom of the inner cavity of the lower casing in interval; a dust discharge outlet (8) is arranged at the surrounding end face of the dust guard (7). Compared with the prior art, the utility model realizes compact structure, small size and simple production technology and reduces the using cost obviously.

Description

The heavy-duty car dry-type air cleaner

(1) technical field:

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

(2) background technique:

Heavy-duty car air-strainer of the prior art, its body is the horizontal circular structure normally.Exist not enough: the huge and complex manufacturing of volume structure has caused the user cost of product to increase.

(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 compact structure, the heavy-duty car dry-type air cleaner that user cost is low.

For achieving the above object, the technological scheme of the utility model heavy-duty car dry-type air cleaner is achieved in that and mainly comprises lower shell body and be connected with upper shell and filter core into and out of tracheae respectively; Its improvement is: at described lower shell body and the involutory interior top of chamber that connects and composes of upper shell, be fixed with the whirlwind sleeve; On the upper shell of described relatively whirlwind sleeve cylindrical, be provided with suction tude; At described whirlwind barrel bore, be the spacer ring cover and be connected with filter core; Described filter core inner chamber upper end is communicated with the steam outlet pipe of top of chamber in the upper shell; Between described filter core lower end and lower housing cavity bottom, be spacing and be provided with dust blocking tray; On the described dust blocking tray periphery end face, be provided with dust exhaust port.

The utility model is taked above-mentioned compact structure, has realized that volume is little and production technology is simple, compares with prior art, has obviously reduced its user cost.

(4) description of drawings:

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

Fig. 2 is that A-A among Fig. 1 is to sectional view;

Fig. 3 is that B-B among Fig. 2 is to partial sectional view.

(5) embodiment:

Fig. 1-shown in Figure 3.This heavy-duty car dry-type air cleaner mainly comprises lower shell body 6 and is connected with upper shell 2 and filter core into and out of tracheae respectively; At described lower shell body 6 and the upper shell 2 involutory interior top of chamber that connect and compose, be fixed with whirlwind sleeve 4; On the upper shell 2 of described relatively whirlwind sleeve 4 cylindricals, be provided with suction tude 3; At described whirlwind sleeve 4 inner chambers, be the spacer ring cover and be connected with filter core 5; Described filter core 5 inner chambers upper end is communicated with the steam outlet pipe 1 of top of chamber in the upper shell 2; Between described filter core 5 lower ends and lower shell body 6 intracavity bottoms, be spacing and be provided with dust blocking tray 7; On the described dust blocking tray 7 peripheral end faces, be provided with dust exhaust port 8 (Fig. 1, Fig. 2, shown in Figure 3).Described filter core 5 is to be the spacing ring set by two tubular papery metafiltration cores to join and constitute (shown in Figure 1).When heavy-duty car is worked, what be mingled with dust particle treats air filtering (among Fig. 1 shown in the direction of arrow), enter the housing inner chamber and through the wind direction water conservancy diversion of whirlwind sleeve 4 cylindricals by suction tude 3, make the dust particle for the treatment of in the air filtering enter the housing intracavity bottom, by stopping of dust blocking tray 7, dust particle by the air-flow rotating flow that enters intracavity bottom to, advance lower shell body 6 intracavity bottoms by the dust exhaust port on the dust blocking tray 7 peripheral end faces 8 row and accumulate (Fig. 1, Fig. 2, shown in Figure 3).Treat air filtering after after the dual filtering of filter core 5, the steam outlet pipe 1 by top of chamber in the upper shell enters in the motor work (shown in Figure 1).

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