Abstract
The utility model relates to an efficient air filter, which comprises an upper cover, a middle housing, a lower cover, a clamp, a rotational flow cover, a main filter core and a safe filter core, wherein, the safe filter core adopts a papery cylindrical structure; an upper end cover which is formed by normal-temperature fast curing glue and ensures that a safe filter core framework and a filter paper are fixed is arranged at the upper end of the safe filter core; a lower end cover for glue injection is arranged at the lower end of the safe filter core; and a sealing glue ring is sleeved at the upper end of the safe filter core framework. The safe filter core adopts the lower end cover foamed by polyurethane, the upper end cover formed by the normal-temperature fast curing glue, and the safe filter core framework which is injection-molded and the papery cylindrical filter core. Therefore, the utility model can effectively improve filtration efficiency of the secondary filtration, ensure requirement of the ash-storage amount, improve the reliability, the durability of the air filter, and convenience of use and maintenance, and effectively protect an engine.
Description
Technical field
The utility model relates to a kind of high efficiency air filter.
Background technology
At present, be applied to the air filter of internal combustion engine, engineering machinery, special type or special-purpose vehicle, be divided into metal-air cleaner and plastics air filter two big classes according to material.The filtering material that safe filter core (secondary filter) in the normal at present plastics air filter that uses adopts is generally nonwoven, its filtering efficiency is low, the difficult control of filtering accuracy, and the filter core in the cleaner adopts the sealing strip end face to compress sealing, sealing was lost efficacy easily, cause the dust short circuit, dust impurity directly enters engine, in case main filter core lost efficacy, very easily cause engine early to grind, other has some series connection plastic air filter version cost height, and it is big to take up room, and is not easy the assembling of car load layout.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple in structure, filtering efficiency is high, the high efficiency air filter of good filtration effect.
The utility model adopts following technical scheme:
The utility model comprises loam cake, middle casing, lower cover, clamp, cyclone cover, main filter core and safe filter core, it is characterized in that described safe filter core adopts the papery tubular structure.Described safe filter core upper end be provided with safety frame of filter element and filter paper fixing solidify the upper end cover that glue forms fast by normal temperature, there is the bottom end cover of injecting glue the lower end of safe filter core, the upper end of safe frame of filter element is set with O-ring seal.
The utility model good effect is as follows: the utility model safety filter core adopts the polyurethane foam bottom end cover; adopt normal temperature to solidify the glue upper end cover fast; adopt injection mo(u)lding safety frame of filter element; and papery tubular element; use the utility model can effectively improve the filtering efficiency of secondary filter; guarantee the requirement of storage ash amount, improve the convenience of reliability, durability and the application maintenance of air filter, can protect engine more effectively.The empty filter of the utility model performance empty filter form that is better than connecting, its space is little, and cost is low.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model safety filter cartridge construction schematic diagram.
Accompanying drawing 3 is the utility model safety frame of filter element structural representation.
In the accompanying drawings: 1 safe filter core, 2 safe frame of filter element, 3 O-ring seals, 4 upper end covers, 5 filter paper, 6 bottom end covers, 7 loam cakes, 8 middle casings, 9 lower covers, 10 clamps, 11 cyclone covers, 12 main filter cores.
The specific embodiment
The utility model comprises loam cake 7, middle casing 8, lower cover 9, clamp 10, cyclone cover 11, main filter core 12 and safe filter core 1, loam cake 7 is fastening with middle casing 8 usefulness tapping screws, cyclone cover 11 usefulness tapping screws tighten on the installing hole of loam cake 7, safe filter core 1 top has the screw thread of injection mo(u)lding and the threaded engagement of loam cake 7 to tighten, O-ring seal 3 on loam cake 7 and the safe filter core 1 is compressed, play the effect of sealing and location, radial expansion volume when 12 polyurethanes by foaming of main filter core cooperate with loam cake seals and locatees, clamp 10 is assembled on the lower cover 9 and can rotates flexibly, and utilizes interference fit to carry out self-locking lower cover 9 is locked on the middle casing 8.The safe filter core 1 that the utility model air filter adopts is a papery fold structure, and bottom end cover 6 adopts the polyurethane foam moulding, and normal temperature solidifies the upper end cover 4 of glue formation fast with filter paper 5 and safe frame of filter element 2 adhering and sealings, has improved the assembly filtration reliability.The utility model air filter is an all-plastic structure, and is simple and compact for structure, sealing is reliable, filter efficiency is high, and the user is easy to operate, can effectively improve engine running environment, prolongs engine service life greatly.
