Description
Technical field
The invention belongs to and belong to the automobile-use parts, be meant a kind of improved polyurethane air filter core especially.
Background technique
Air cleaner cartridge is the protective gear that the air inlet of motor cylinder barrel piston combustion zone purifies, and generally is divided into cylindrical and cuboid shape according to the difference of automobile model.The structural behaviour of filter core directly has influence on the usefulness performance and the working life of motor.The various filter cores of selling on the market mostly adopt paper to filter and add protective net now, and service time is short, ventilate function is poor, becomes the disposable consumable products of automobile protective, has increased consumption, sometimes dust greatly also often causes motor to feel suffocated, and increases oil consumption, has reduced power.
A kind of motor vehicle air filter core is disclosed in the utility model patent of the patent No. 200520110204.7, its main structure for be provided with columnar in, outer leaching net 12,9, in, be provided with filter layer 11 between the outer leaching net, 10, the cylinder center hole is air outlet 14, cylindrical filter body one end is provided with hat upper end cap 1, the other end is provided with pallet 8, in the cylindrical shape, outer leaching net is connected with pallet 8 with upper end cap 1 respectively with the filter layer two ends, outside described pallet 8, be set with the filter core supporting disk 6 of fixedlying connected with pallet, be coated with the sponge filter layer 4 of foaming structure on the filter body outer wall between described upper end cap 1 lower edge and the filter core supporting disk 6, the sponge filter layer is coated with the mesh skeleton 3 that is used for fixing the sponge filter layer.Though the sponge filter layer that is provided with can be protected inner papery filter layer, in the working life that can improve the papery filter core to a certain extent, does not fundamentally solve the problem that papery filter core ventilate function is poor, operating cost is high.
Summary of the invention
The object of the present invention is to provide that a kind of ventilating performance is good, the improved polyurethane air filter core of long service life and energy-conserving and environment-protective.
Overall technology design of the present invention is:
Improved polyurethane air filter core comprises shell, is arranged at filter layer and the seal ring on the shell 1 in the shell; Described filter layer is the section waviness that curves of polyurethane foam sheet 6 or the continuous structure of broken line shape, and polyurethane foam sheet 6 is ventilative micropore or microgap structure.
Concrete structure design of the present invention also has:
The section waviness that described polyurethane foam sheet 6 curves or the continuous structure of broken line shape preferably are adopted as a kind of in " one " font or the annular.
When the present invention is applied to cylindrical air-strainer, shell comprises the inside and outside filter screen 7,4 that concentric spacing is provided with, be packaged in upper end cap 3, the lower end cap 8 on the upper and lower surface of inside and outside filter screen 7,4, the center hole of Inner filter net 7 is an air outlet hole 2, upper end cap 3 be provided with at least one annular seal circle 1.
When the present invention was applied to the cuboid shape air-strainer, shell was the rectangle housing, and the housing upper surface is provided with seal ring 1, and housing is coated with sheet metal 9 structures of protective coating 10 for the surface.
Be to guarantee that seal ring 1 realizes good sealing, the just shaping and the assembling of protective coating 10 and seal ring 1 simultaneously, seal ring 1, protective coating 10 adopt a kind of in rubber or the polyester plastics or its in conjunction with as making material.
For being easy to that polyurethane foam sheet 6 is bent shaping, the polyurethane foam sheet 6 preferred a kind of conduct making materials that adopt in soft or the semi-hard polyurethane foam.
For further realizing protection with 6 location of the polyurethane foam sheet after the bending and to it, inside and outside at least one side of polyurethane foam sheet 6 is coated with location protecting wire net 5, can be apparently, location protecting wire net 5 can also be arranged between the two-layer polyurethane foam sheet 6, does not break away from essence of the present invention.Optimized technical scheme is that the inside and outside both sides of polyurethane foam sheet 6 all are coated with location protecting wire net 5.
Location protecting wire net 5 is preferred to adopt a kind of in metals or the plastics or its in conjunction with as making material.
When the present invention was applied to cylindrical air-strainer, optimized technical scheme was the polyurethane foam sheet 6 that is provided with location protecting wire net 5 for around the axis setting of inside and outside filter screen 7,4 and extend vertically and sidewall offers the loop configuration of the fold of axial distribution.
When the present invention was applied to the cuboid shape air-strainer, optimized technical scheme was that the described polyurethane foam sheet 6 that is provided with location protecting wire net 5 is arranged in the housing, and its integral body is that along continuous straight runs extends and section is the continuous structure of ripple or the bending of broken line shape.
Substantive distinguishing features that the present invention is obtained and significant technological progress are:
Polyurethane foam sheet with micropore or microgap structure is as filtering material, thoroughly replace the papery filter core, ventilating performance is good, show through experimental result, than using common filter core fuel-economizing 5%-10%, increasing power 5%, because of it can repeatedly clean, use repeatedly, so long service life is about 10-30 times (be the 3000-5000 kilometer working life of existing papery filter core) having the papery filter core now.Adopt the location protecting wire net that polyurethane foam sheet is realized location and protection, make it more easily realize installation and maintenance.
