Abstract
The utility model discloses a kind of three-stage filtration components and its dirt cup in dust cup of dust collector, the filter assemblies include the nano fibrous membrane of the air filtration cotton of outer layer, intermediate extra large pa layer and internal layer, it is bonded between air filtration cotton and extra large pa layer by hot melt adhesive, passes through suture connection between extra large pa layer and nano fibrous membrane.The filter assemblies are suitable for being set in cyclone body dirt cup.The utility model filter assemblies can reduce the blocking of extra large pa layer while increased efficiency, achieve the effect that degerming while filtering grit.
Description
Technical field
The utility model belongs to cleaner technology field, specially a kind of three-stage filtration component in dust cup of dust collector
And its dirt cup.
Background technique
Dirt cup is the dust collect plant of dust catcher, and filter assemblies are typically provided in dirt cup, and the filter capacity of filter assemblies is to inhale
One of the important measurement index of dirt device quality.It is low or easy to be stifled usually to have filter efficiency for filter device in existing dust catcher
The technical issues of plug, however the two technical indicators are originally often not easy to take into account.
Summary of the invention
The purpose of this utility model is that proposing that a kind of filter efficiency is high, and susceptible to plugging filter assemblies are not allowed.
The purpose of this utility model is achieved through the following technical solutions.
A kind of three-stage filtration component in dust cup of dust collector, the filter assemblies include outer layer air filtration cotton,
The nano fibrous membrane of intermediate extra large pa layer and internal layer is bonded between the air filtration cotton and extra large pa layer by hot melt adhesive, described
Pass through suture connection between extra large pa layer and nano fibrous membrane.
Further, the quantity for spray of the hot melt adhesive is 0.2 ~ 0.5g/m2。
Further, the hot melt adhesive is polyolefin resin or polyamide.
Further, the filter cotton is non-woven fabrics filter cotton, glass fiber filter cotton or active carbon filter cotton.
Further, the nano fibrous membrane is electrospinning copolyimide nano fibrous membrane.
A kind of dust cup of dust collector being provided with the three-stage filtration component.
Further, the dirt cup is cyclone body dirt cup.
Further, the dirt cup outer wall is equipped with air inlet, and the three-stage filtration material surrounds hollow structure and is arranged in dirt
Cup filter element position, three-stage filtration member collapses have circumferentially distributed fold；The air inlet is corresponding with filter core position.
Further, the central axis of the fold and dust cup of dust collector is at 10 ~ 20 degree of inclination angle, the air inlet side of air inlet
To opposite with the inclined direction of fold.
The beneficial effects of the utility model are:
1) the utility model adds one layer of air filtration cotton in the outside of extra large pa layer, filters out the substance of bulky grain first, from
And extra large pa layer is set to be not easy to block, and improve filter efficiency；
2) it is connected between extra large pa layer and air filtration cotton by hot melt adhesive layer, connection fastening can reduce windage；
3) nano fibrous membrane of internal layer can further filter bacteria, so that making this filter assemblies not only has the work of dedusting
With simultaneously can be with degerming；
4) nano fibrous membrane and Hai Pa layers it is small to be completely embedded gap, and nano fibrous membrane is not allowed directly by suture connection
It is easy to fall off.
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
Detailed description of the invention
Fig. 1 is the utility model three-stage filtration component structure diagram；
Fig. 2 is the structural schematic diagram of the utility model dust cup of dust collector.
Appended drawing reference: 1. air filtration cotton layers；2. extra large pa layer；3. nano fibrous membrane；4. filter core；5. fold；6. dirt cup into
Wind direction.
Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of three-stage filtration component in dust cup of dust collector, the filter assemblies include the sky of outer layer
The nano fibrous membrane 3 of gas filter cotton 1, intermediate extra large pa layer 2 and internal layer passes through heat between the air filtration cotton 1 and extra large pa layer 2
Melten gel bonding passes through suture connection between the sea pa layer 2 and nano fibrous membrane 3.
The quantity for spray of hot melt adhesive is 0.2 ~ 0.5g/m2.Spraying edge position as far as possible when spraying, quantity for spray is excessive to influence two
Compactness between filter layer, will increase windage.The hot melt adhesive is polyolefin resin or polyamide.The filter cotton is
Non-woven fabrics filter cotton, glass fiber filter cotton or active carbon filter cotton.The nano fibrous membrane is that electrospinning copolyimide is received
Rice tunica fibrosa.
Embodiment 2
As shown in Fig. 2, a kind of dust cup of dust collector for being provided with three-stage filtration component described in embodiment 1.
The dirt cup is cyclone body dirt cup.The dirt cup outer wall is equipped with air inlet, and the three-stage filtration material surrounds hollow
For structure setting in 4 position of dirt cup filter core, three-stage filtration member collapses have circumferentially distributed fold 5；The air inlet and filter core position
Set correspondence.The central axis of the fold 5 and dust cup of dust collector is at 10 ~ 20 degree of inclination angle, the air inlet direction of air inlet and fold
Inclined direction it is opposite.Opposite air inlet direction is conducive to increased efficiency.
