Abstract
The utility model relates to a two-stage air filter device for a heavy motor truck. According to two-stage air filter device, a swirl pipe type air filter and a dry paper air filter are integrally welded; the dry paper air filter is positioned on the upper part of the swirl pipe type air filter; the front side of a shell of the swirl pipe type air filter is provided with an air inlet which is bent upward; and one axial side of the dry paper air filter is provided with an air outlet. By a combined filtration mode, the swirl pipe type air filter can perform rough filtration on most of dust, the rough filtration efficiency can reach 95 percent, and the fine filtration process is finished by the dry paper air filter, so that clean air required by an engine can be provided. The two-stage air filter device is used for the heavy motor truck; and filtration efficiency is increased, the service life is prolonged, and maintenance cost is reduced.
Description
Technical field
The utility model relates to the air filter for automobile device, specifically a kind of heavy duty truck double-stage air cleaner device.
Background technique
Air-strainer is one of most important component of engine accessory power rating, and its structure and performance and filtering effect directly have influence on user's service time, expense and motor working life, therefore more and more receive people's attention; At present, the air-strainer of most of homemade heavy duty truck is the dry type paper air cleaner, and this air-strainer can only be applied in environment and transport good operating modes such as highway preferably; In the more abominable operating modes such as mining area of environment; Just maladjusted problem is arranged, filter efficiency reduces, and shorten working life; Cost of upkeep increases; Even might cause phenomenon such as motor premature wear scuffing of cylinder bore, and change this situation, just must change the filter type of vehicle air cleaner.
The model utility content
In order to improve the filter efficiency of air-strainer, increase working life, reduce the maintaining cost, the utility model provides a kind of novel double-stage air cleaner device, below common dry type paper air cleaner, increases swirl tube air cleaner.
Concrete architecture advances technological scheme is following:
A kind of heavy motor truck double-stage air cleaner device; Said double-stage air cleaner device comprises swirl tube air cleaner 1 and dry type paper air cleaner 2; Said swirl tube air cleaner 1 is welded as a whole with dry type paper air cleaner 2, and dry type paper air cleaner 2 is positioned at the top of swirl tube air cleaner 1;
Swirl tube air cleaner housing front side is provided with bending suction port 3 upwards, and the axial side of dry type paper air cleaner is provided with air outlet 4.
The useful technique effect of the utility model is embodied in the following aspects:
1, the filter type of air-strainer changes eddy flow tubular type and dry type papery cartridge combination formula filter type into by single dry type papery filter element filtering;
2, swirl tube air cleaner carries out coarse filtration with most of dust, and coarse filtration efficient is up to 95%, and the dry type paper air cleaner is then accomplished the fine filtering process, to provide motor needed clean air;
3, the utility model is used for heavy duty truck, and filter efficiency increases, and prolong working life, and the maintaining expense reduces.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the side view of Fig. 1.
Among the figure: swirl tube air cleaner 1, dry type paper air cleaner 2, suction port 3, air outlet 4, cage assembly 5, ash collecting box assembly 6, arrange cyclone tube 7, wing bolt assembly 8, sealing rubber ring 9, support 11, dividing plate 12 more.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2; Heavy duty truck double-stage air cleaner device; Comprise swirl tube air cleaner 1 and dry type paper air cleaner 2; Mode with welding between swirl tube air cleaner and the dry type paper air cleaner is connected, and swirl tube air cleaner housing front side end has suction port 3, and the axial side of dry type paper air cleaner is provided with air outlet 4.
Swirl tube air cleaner 1 comprises cage assembly 5, ash collecting box assembly 6, arranges cyclone tube 7 more, wing bolt assembly 8, sealing rubber ring 9, support 11 and dividing plate 12.
Air gets into empty filter through the suction port 3 of swirl tube air cleaner, earlier with the many rows of entering cyclone tubes 7, through the filtration of cyclone tube; The dust that particle is bigger is filtered; Fall following ash collecting box assembly 6 the insides, the part dust is discharged empty filter by external dust-exhausting bag, and relatively clean air upwards flows after changing direction; Flow to the dry type paper air cleaner; Support 11 is installed on the ash collecting box assembly 6 through wing bolt assembly 8, and dividing plate 12 is installed on the support 11, is used for supporting many row's cyclone tubes 7.
Dry type paper air cleaner 2 mainly comprises main filter core assembly 13 and safe filter core assembly 14; Main filter core filters the dust that swirl tube air cleaner does not filter out, and the function of safe filter core is when accidental damage appears in main filter core, to guarantee the Security of motor.
