Abstract
The utility model relates to the field of a filter, in particular to an air cleaner element with a protection function. The air cleaner element comprises an inner tubular metal net, an outer tubular metal net and filter paper arranged between the inner tubular metal net and the outer tubular metal net, wherein a protective plate is arranged between the outer tubular metal net and the filter paper; after the high speed air flow mingled with particles enters an air cleaner, the high speed air flow does not act on the filter paper directly due to the blocking effect of the protective plate, the high speed air flow flows towards the side face of the protective plate along the outer surface of the protective plate, thus the protective plate plays a protecting role on the filter paper, and the service life of the filter is prolonged. Furthermore, the structure of the air cleaner element is simple, the cost is low and the filtering effect is good.
Description
Technical field
The utility model relates to filter cleaner field, relates in particular to a kind of air cleaner cartridge with safeguard function.
Background technique
At present, the demand of engineering vehicle in industrial production is more and more.And the working environment of most of engineering vehicle is more severe, in the environment that particularly dust and particulate matter are many especially in air, these air that are being mingled with dust and particulate matter directly affect the working life of internal-combustion engine.
Combustion air cleaner of the prior art filter core used be generally to protect filter paper with the gather wire netting of rhombic hole of one deck.But, in actual conditions, because the air velocity of engineering vehicle air filter housing suction port is very high, the high-speed air air-flow of these Particulate Inclusion things, directly acts on filter paper, can cause the distortion of filter paper, even can damage filter paper, reduce filtering effect and the working life of filter paper.Therefore, need to develop a kind of filter core with protective function, to improve the filtering effect of filter cleaner, extend its working life.
Therefore,, for above deficiency, the utility model provides a kind of air cleaner cartridge with safeguard function.
Model utility content
(1) technical problem that will solve
The purpose of this utility model is to provide a kind of air cleaner cartridge with safeguard function and enters to solve the high-speed air air-flow of Particulate Inclusion thing the problem that air-strainer damages filter paper or makes filter paper distortion.
(2) technological scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of air cleaner cartridge with safeguard function, it is characterized in that: it comprise internal layer tubular wire netting, outer tubular wire netting and be arranged on internal layer tubular wire netting and outer tubular wire netting between filter paper, between outer tubular wire netting and filter paper, be provided with protection apron.
Wherein, upper end, the lower end of internal layer tubular wire netting and outer tubular wire netting are respectively arranged with upper cover and lower cover.
Wherein, protection apron is corresponding with the suction port of air-strainer.
Wherein, protection apron be shaped as cylindric.
Wherein, the length of protection apron is more than or equal to the internal diameter of air-strainer suction port.
Wherein, the material of protection apron is plastics.
Wherein, protection apron is transparent PVC＝polyvinyl chloride, and its thickness is 0.5～1.0mm.
(3) beneficial effect
Technique scheme tool of the present utility model has the following advantages: the air cleaner cartridge that the utility model provides arranges protection apron between outer tubular wire netting and filter paper; when the high-speed air air-flow of Particulate Inclusion thing enters after air-strainer; due to the barrier effect of protection apron; it is not to directly act on filter paper; but side flow along from the outer surface of protection apron to protection apron; protection apron has played protective action to filter paper like this; thereby extend working life of filter cleaner, and this filter cartridge construction statement of account, cost are low and good filtration effect.
Brief description of the drawings
Fig. 1 is the utility model embodiment air cleaner cartridge sectional drawing.
In figure, 1: internal layer tubular wire netting; 2: outer tubular wire netting; 3: filter paper; 4: protection apron; 5: upper cover; 6: lower cover.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the air cleaner cartridge of what the utility model provided have safeguard function comprise internal layer tubular wire netting 1, outer tubular wire netting 2 and be arranged on internal layer tubular wire netting 1 and outer tubular wire netting 2 between filter paper 3, upper end, the lower end of internal layer tubular wire netting 1 and outer tubular wire netting 2 is respectively arranged with upper cover 5 and lower cover 6, upper cover 5 and lower cover 6 are fixed on the two ends of filter paper 3 and tubular wire netting by PU injection moulding, between outer tubular wire netting 2 and filter paper 3, be provided with protection apron 4, protection apron 4 is corresponding with the suction port of air-strainer.
Like this; when the high-speed air air-flow of Particulate Inclusion thing enters after air-strainer by suction port; due to the barrier effect of protection apron 4; high velocity air is not to directly act on filter paper 3; but side flow along from the outer surface of protection apron 4 to protection apron 4; airborne particulate matter just can directly not beaten on filter paper 3 and damage filter paper 3, thereby filter paper 3 has been played to protective action.
Wherein, the shape of protection apron 4 is consistent with the shape of wire netting, for cylindric, is convenient to guide air flow; The length of protection apron 4 is more than or equal to the internal diameter of air-strainer suction port, to meet stopping of high velocity air to entering by suction port; The material of protection apron 4 is plastics, and particularly, protection apron 4 is transparent PVC＝polyvinyl chloride, and its thickness is 0.5～1.0mm.
The utility model is specially adapted to the more severe engineering vehicle of working environment, can certainly be applicable to other vehicles.
In sum, the air cleaner cartridge that the utility model provides arranges tubular protection apron 4 between outer tubular wire netting 2 and filter paper 3, when the high-speed air air-flow of Particulate Inclusion thing enters after air-strainer, due to the barrier effect of protection apron 4, high velocity air is not to directly act on filter paper 3, but side flow along from the outer surface of protection apron 4 to protection apron 4, airborne particulate matter just can directly not beaten on filter paper 3 and damage filter paper 3, like this filter paper 3 is played to protective action, thereby extend the working life of filter cleaner, and this filter cartridge construction statement of account, low and the good filtration effect of cost
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
