Abstract
The utility model relates to a cylindrical air filter, and in particular relates to a cylindrical air filter, the shell of which is assembled and manufactured by parts of different materials. The cylindrical air filter mainly solves the problems that an existing integral metal cylinder air filter is too heavy, a single-plastic cylinder air filter is poor in harsh environment resistance capacity, and the disassembly of the two types of air filters is pretty difficult. The cylindrical air filter comprises an end cover, a cylindrical shell, an upper cover and a filter element, wherein the end cover and the upper cover are mounted at the two ends of the cylindrical shell, the filter element is placed inside the cylindrical shell, an air outlet is formed in the end cover, and an air inlet is formed in the shell. The cylindrical air filter is characterized in that the top part at one end of the cylindrical shell is clamped into a rectangular groove of the end cover through a clip to form an accommodating cavity with a clip plate, the cylindrical shell is provided with an arc raised rib on the extended segment of the clip, the arc raised rib is clamped into an arc groove of a fixing ring matched with the rib, the other end of the cylindrical shell is assembled with the upper cover, the cylindrical shell and the upper cover are fixed through a buckle after being assembled, and a rubber sealing ring is arranged between the cylindrical shell and the upper cover. The cylindrical air filter provided by the utility model is mainly applied to a long-distance transport vehicle and construction machinery.
Description
Technical field
The utility model relates to a kind of air filter, and particularly housing adopts material parts not of the same race to carry out the air filter of assembling manufacturing.
Background technology
At present, the filtration environment that on market, long-distance vehicle and engineering machinery are cope with bad, extensively adopt the air filter of cylindrical shape, pleated papery filter element, and this type of air filter mainly contains two kinds of structures.
The US3078650 U.S. Patent Publication a kind of prior art structure of air filter, this air filter has a tubular metal housing, this housing has an import, for the air that contains dust, enters.Columnar pleating papery filter element is arranged in housing.One clean air outlet is communicated with pleating papery filter element inner chamber.Sealing between pleating papery element and outlet provides by the liner be fixed on filter element, and the end wall engagement of liner and tubular shell is fixed by screw nut assembly.
The US4720292 U.S. Patent Publication prior art structure of another kind of cylindrical shape air filter.In its preferred embodiment, the housing of air cleaner is made of plastic, and columnar pleating papery filter element is arranged in housing.Pleating filter element has an openend be communicated with air outlet slit.The openend of filter element has an annular end cap, with the elastomer foam material, makes.Filter element is arranged on the air outlet slit pipe, and provides sealing by end cap and pipe-type outlet components bonding.In order to manufacture the air cleaner that uses plastic casing, generally need to manufacture the mould of housing.Usually utilizing Split type die to manufacture housing, to adapt to its change dimensionally and in the locational change of air intlet, is quite expensive and manufacture the instrument that the mould of various air filters that may purposes uses.
Summary of the invention
The purpose of this utility model is to provide a kind of ability that had both possessed metal shell construction cope with bad working environment, possess again that the plastic casing quality is light, the air filter of filter element easy-to-install advantage, mainly solve existing bulk metal cylinder air filter too heavy, and unitary plastic cylinder air filter adverse environment resistant ability, and the more difficult technical problem of dismounting.
The technical scheme that the utility model adopts is: a kind of cylindrical shape air filter, comprise end cap, cylindrical housings, upper cover, filter element, end cap and upper cover are arranged on the cylindrical housings two ends, filter element is placed in cylindrical housings, end cap is provided with gas outlet, one air inlet is arranged on housing, it is characterized in that cylindrical housings is metal shell, end cap and upper cover are working of plastics, rectangular recess and clamp that cylindrical housings one end top snaps in end cap with clamp form cavity volume, cylindrical housings has an arc convex tendon to snap in the arc groove with its coupling retainer ring in the extension of clamp, and carry out angle orientation with rivet and strengthen bonding strength.The cylindrical housings other end and upper cover are assembled, and after assembling, with buckle, are fixed, and between cylindrical housings and upper cover, are provided with sealing rubber ring.Flow deflector is installed on air inlet, after flow deflector guiding dust laden air rotates coarse filtration in housing, passes through filter core.Filter element adopts the version of radial seal.
The beneficial effects of the utility model are: the realization of composite material air filter.The utility model adopts the metal material housing, firm in structure, can adapt to the severe working environments such as HTHP, and manufacturing process is simple.End cap and upper cover can effectively alleviate assembly weight after using plastic material, and satisfying the market reduces the demand of complete vehicle quality.The connected mode of end cap and cylindrical tube can help the user to complete dismounting and the assembly of filter element under need not the condition by any instrument, makes maintenance and more changes jobs and become simple and convenient.Can need not frock or the condition of welding procedure under complete dismounting and the assembly of metal shell and plastic end cover, solved the assembly problem between the different materials part and simplified production process.
