Abstract
The utility model provides a multilayer nanofilm non-woven filter element. The filter element comprises PU (poly urethane) adhesive end covers, a supporting layer and filter layers, wherein each filter layer comprises a non-woven filter layer and nanofilm composite layers; the filter layers are bonded above the supporting layer; a PU end cover of the filter element is arranged at the two ends of the supporting layer respectively; the supporting layer is made of a steel screen; the non-woven filter layers are folded into Z shape; the number of the nanofilm composite layers is 3-6; the nanofilm composite layers adhere to the outer surfaces of the non-woven filter layers; each nanofilm composite layer can be opened independently; each PU adhesive end cover comprises a PU adhesive end cover body and a seal ring; and the PU adhesive end cover bodies and the seal rings are integrally formed. Compared with the prior art, the recycling multilayer nanofilm non-woven filter element has high filter precision and large pollutant receiving capacity, can be recycled and prolong the service cycle and is more energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of motor vehicle fittings, relates in particular to a kind of multi-layer nano-film nonwoven filter core that reuses.
Background technology
Conventional filter, for example the filter core kind of air filter, fuel filter and oil filter mainly contains sawdust filter core, single meltblown fibers filter core, metal screen filter core and paper filter core, sawdust filter core air permeability is little, resistance is large, cracky passage when pressure is large, the technique simple procedures is loaded down with trivial details, unsuitable industrialization production; Wire netting filter element filtering low precision, weight is large, cost is high; Single meltblown fibers filter core is because by single radially Wrapping formed after the homofil melting, easily collapse-deformation affects filter effect under the HTHP effect; The aperture of widely used paper filter core is single, and filtering accuracy is low, pollutant holding capability is little, and service life is short, make the easy filter cake effect that produces of time spent at temperature and pressure, and make in a large number use trees of wood pulp paper, waste resource, and it is long to blow clearly the filter core dust time, easily causes secondary pollution.
Given this, be necessary to provide a kind of circular regeneration multi-layer nonwoven fabrics nanometer film filter core to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of energy-conserving and environment-protective, and filtering accuracy is high, the multi-layer nano-film nonwoven filter core that repeatedly utilizes capable of circulation.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of multi-layer nano-film nonwoven filter core comprises: PU glue end cap, supporting layer, filter course; Described filter course comprises: nonwoven filter course, nanometer film composite bed, described filter course are bonded in the supporting layer top, and respectively there is a PU glue end cap at the supporting layer two ends, and described supporting layer is that expanded metal lath consists of.
As the further improvement of the technical program, described nonwoven filter course is folded into Z-shaped, and described nanometer film composite bed is three to six layers, adheres to nonwoven filter course appearance, and every one deck nanometer film composite bed can be opened separately.
As the further improvement of the technical program, described PU glue end cap comprises PU glue end cover body and sealing ring, described PU glue end cover body and the sealing ring structure that is formed in one.
Compared with prior art, the utility model multi-layer nano-film nonwoven filter core, filtering accuracy is high, and pollutant holding capability is large, and life cycle is long, and energy-conserving and environment-protective.
[description of drawings]
Fig. 1 is the structural representation of multi-layer nano-film nonwoven filter core described in the utility model when being cylindrical shape.
Fig. 2 is A shown in Figure 1 section enlarged drawing.
[specific embodiment]
See also Fig. 1-shown in Figure 3, the utility model provides a kind of multi-layer nano-film nonwoven filter core, comprising: PU glue end cap 1, supporting layer 2, filter course 3; Described filter course 3 comprises: nonwoven filter course 31, nanometer film composite bed 32, described filter course 31 is bonded in supporting layer 2 tops, respectively there is a PU glue end cap 1 at supporting layer 2 two ends, described supporting layer 2 consists of for expanded metal lath, described nonwoven filter course 31 is folded into Z-shaped, described nanometer film composite bed 32 is three to six layers, adheres to nonwoven filter course 31 appearances, and every one deck nanometer film composite bed can be opened separately; Described PU glue end cap 1 comprises PU glue end cover body 11 and sealing ring 12, described PU glue end cover body and the sealing ring structure that is formed in one.
Vehicle Driving Cycle 2000-5000 kilometer, when pressure drag raises, illustrate that the dust greasy dirt is too much, air feed is for shortage of oil, the wind speed and the flow that stop filter core, have influence on normal working of engine, at this time filter core need to blow clearly, only need to tear the ground floor of nanometer film composite bed 32 and remove and get final product, the time spent simple to operate be short, and only needs just can easily be finished in 5 minutes, when next resistance is large by the time, use the same method and tear second layer nonwoven nanometer film and get final product, PU glue end cover body and the sealing ring structure that is formed in one is conducive to the raising of filtering accuracy.
Multi-layer nano-film nonwoven filter core described in the utility model can be made into cylindrical shape, also can the side's of being made into plate shape, and its filtering accuracy is high, and the air cleaning rate reaches 99.5%, and can recycle, and prolongs life cycle, more energy-conserving and environment-protective.
The above; it only is most preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; any those of ordinary skill in the art; do not breaking away from the technical solutions of the utility model scope situation; utilize the method content of above-mentioned announcement that technical solutions of the utility model are made many possible changes and modification, all belong to the scope of claims protection.
