Abstract

The utility model discloses a heavy automobile composite dry-wet air cleaner. Inside an inner cavity formed by a lower casing (9) and an upper casing (1) which are aligned and connected, an air intake pipe (3) is corresponding to filtering engine oil (8) at the bottom of the inner cavity of the lower casing through an air inlet (6); the liquid face of the filtering engine oil (8) is connected with an oil-splash-preventive plate (7); the upside of the oil-splash-preventive plate (7) is connected with a filter screen (10) in interval; the upside of the filter screen (10) is connected with a fan blade plate (5), the upside of which is connected with the filter screen (11) in interval; the upside of the filter screen (11) is connected with an air flow guide bracket (4), the air outlet of which is corresponding to a filter core (2) which is fixedly connected with the top of the inner cavity of the upper casing with the interval; the inner cavity of the filter core (2) is communicated with an air output pipe (12). Compared with the prior art, the utility model realizes compact structure, small size and simple production technology and reduces the using cost obviously.

Description

Heavy-duty car is done wet composite air filter cleaner

(1) technical field:

The utility model relates to engine air filter; Be specifically related to a kind of heavy-duty car and do wet composite air filter cleaner.

(2) background technique:

Heavy-duty car of the prior art is done wet composite air filter cleaner, and 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, and the heavy-duty car that user cost is low is done wet composite air filter cleaner.

For achieving the above object, the utility model heavy-duty car technological scheme of doing wet composite air filter cleaner is achieved in that and mainly comprises lower shell body and be connected with upper shell and filter screen into and out of tracheae respectively; Its improvement is: in described lower shell body and the involutory inner chamber that connects and composes of upper shell, suction tude is corresponding with the filter oil phase that the lower housing cavity bottom is provided with by inlet hole; On described filter oil level, be connected with the grease proofing plate that spatters; Described grease proofing spattering above the plate, be spacing and be connected with filter screen; On described filter screen, be connected with wind acanthus leaf; Above described wind acanthus leaf, be spacing and be connected with filter screen; On described filter screen, be connected with the air conducting support; The air outlet of described air conducting support, be fixed on upper shell in filter core in the top of chamber to be spacing corresponding; Described filter core inner chamber is communicated with steam outlet pipe.

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. 1 is to echelon sectional view.

(5) embodiment:

Fig. 1-shown in Figure 3.This heavy-duty car is done wet composite air filter cleaner, mainly comprises lower shell body 9 and is connected with upper shell 1 and filter screen into and out of tracheae respectively.In described lower shell body 9 and the upper shell 1 involutory inner chamber that connects and composes, suction tude 3 is corresponding with the filtering machine oil 8 that lower shell body 9 intracavity bottoms are provided with by 5 inlet holes 6 that the housing inner chamber is provided with; On described filtering machine oil 8 liquid levels, be connected with the grease proofing plate 7 (Fig. 1, shown in Figure 2) that spatters; Described grease proofing spattering above the plate 7, be spacing and be connected with braid fabric 10; On described filter screen 10, be connected with wind acanthus leaf 5 (Fig. 1, shown in Figure 3); Above described wind acanthus leaf 5, be spacing and be connected with braid fabric 11; On described filter screen 11, be connected with air conducting support 4 (Fig. 1, shown in Figure 2).The air outlet of described air conducting support 4, be fixed on upper shell 1 in papery metafiltration core 2 in the top of chamber to be spacing corresponding; Described papery metafiltration core 2 inner chambers are communicated with steam outlet pipe 12.Described filter core 2 normally is the spacing ring set by two tubular papery metafiltration cores and joins and constitute (Fig. 1, shown in Figure 2).When heavy-duty car is worked under abominable air ambient, what be mingled with the dust particle and/or the sleet globule treats air filtering (among Fig. 1, Fig. 2 shown in the direction of arrow), enter by suction tude 3 and inlet hole 6 in the filtering machine oil 8 of lower shell body 9 intracavity bottoms, the grease proofing plate 7 that spatters of this moment has played and has prevented that filtering machine oil 8 is subjected to the excessive effect that causes fluid to splash of air-entry suction everywhere.Treat that air filtering is through the wet type coarse filtration of fluid and after passing through the dual dry type filtering of double layer of metal

wire gauze filter

10 and 11 respectively, make the air outlet of coarse filtration air by air conducting support 4, the papery metafiltration core 2 that enters in the upper shell 1 interior top of chamber carries out the essence filter, enters in the motor by steam outlet pipe 12 at last work (Fig. 1, shown in Figure 2).

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.
