Abstract
A kind of composite bed successively encrypts environmental protection filter cotton, comprise the first filter course, the second filter course and the 3rd filter course from top to bottom, described 3rd filter cotton lower end is also provided with chemical fibre blending eyelet fabric, described first filter course comprises and is no less than seven layers of electrostatic layers, described second filter course comprises and is no less than five layers of electrostatic fibre layer, and described 3rd filter course comprises and is no less than eight layers of electrostatic fine fiber layer; Each electrostatic fibre layer is provided with aperture, and every layer, aperture varies in size, and every layer, aperture diminishes from top to bottom gradually, and minimum-value aperture is less than 0.03 micron.The advantage that a kind of composite bed described in the utility model successively encrypts environmental protection filter cotton is, good filtration effect, and the power of pullling that can bear is large, and the life-span is long simultaneously.
Description
Technical field
The utility model relates to the cotton field of air filtration, and particularly a kind of composite bed successively encrypts environmental protection filter cotton.
Background technology
General filter cotton one is that aperture is substantially in the same size, without specially treated, can not play a role in filtering for dust.Dust on human body, on produce, on product quality, on environment, on natural scene attractive in appearance, have impact to the ecological balance.Simultaneously also there is the little thus deficiency causing the life-span short of the power of pullling that can bear in filter cotton of the prior art.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good filtration effect, and the power of pullling that can bear is large, and the composite bed that the life-span is long simultaneously successively encrypts environmental protection filter cotton.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of composite bed successively encrypts environmental protection filter cotton, comprise the first filter course, the second filter course and the 3rd filter course from top to bottom, described 3rd filter cotton lower end is also provided with chemical fibre blending eyelet fabric, described first filter course comprises and is no less than seven layers of electrostatic layers, described second filter course comprises and is no less than five layers of electrostatic fibre layer, and described 3rd filter course comprises and is no less than eight layers of electrostatic fine fiber layer; Each electrostatic fibre layer is provided with aperture, and every layer, aperture varies in size, and every layer, aperture diminishes from top to bottom gradually, and minimum-value aperture is less than 0.03 micron.
First filter course described in the utility model comprises eight layers of electrostatic fibre layer, and described second filter course comprises six layers of electrostatic fibre layer, and described 3rd filter course comprises ten layers of electrostatic fibre layer.
First filter course described in the utility model comprises eight layers of electrostatic fibre layer, and described second filter course comprises eight layers of electrostatic fibre layer, and described 3rd filter course comprises Floor 12 electrostatic fibre layer.
The advantage that a kind of composite bed described in the utility model successively encrypts environmental protection filter cotton is, good filtration effect, and the power of pullling that can bear is large, and the life-span is long simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
1, the first filter course, the 2, second filter course, the 3, the 3rd filter course, 4, chemical fibre blending eyelet fabric.
Detailed description of the invention
A kind of composite bed successively encrypts environmental protection filter cotton, comprise the first filter course 1, second filter course 2 and the 3rd filter course 3 from top to bottom, described 3rd filter cotton lower end is also provided with chemical fibre blending eyelet fabric 4, described first filter course 1 comprises and is no less than seven layers of electrostatic layers, described second filter course 2 comprises and is no less than five layers of electrostatic fibre layer, and described 3rd filter course 3 comprises and is no less than eight layers of electrostatic fine fiber layer; Each electrostatic fibre layer is provided with aperture, and every layer, aperture varies in size, and every layer, aperture diminishes from top to bottom gradually, and minimum-value aperture is less than 0.03 micron.
First filter course 1 described in the utility model comprises eight layers of electrostatic fibre layer, and described second filter course 2 comprises six layers of electrostatic fibre layer, and described 3rd filter course 3 comprises ten layers of electrostatic fibre layer.
First filter course 1 described in the utility model comprises eight layers of electrostatic fibre layer, and described second filter course 2 comprises eight layers of electrostatic fibre layer, and described 3rd filter course 3 comprises Floor 12 electrostatic fibre layer.
During concrete enforcement, the first filter course is mainly made with crude fibre, and increase dust containing capacity, dust containing capacity increases by 20 ﹪ than general filter cotton.Second filter course mainly makes through special process of fines.3rd filter course mainly makes through special process of fines and ultra-fine material, can filter 0.03 micron to more than 1 micron particle diameter dust; Chemical fibre blending eyelet fabric is covered on the 3rd filter course and form composite bed with blancher flatiron, increase cotton pullling intensity and filter rank.
The alternative existing filter bag material of the utility model all products cotton.First filter course, the second filter course and the 3rd filter course are synchronous production, just the 3rd filter course will be laid on above the 3rd filter course by the second filter course fiber (lapping 8 layers) according to special process lapping 10 layers after acupuncture, simultaneously ground floor filter course be laid on the second filter course jointly enter drying tunnel hot melt, sizing, rolling, etc., finally chemical fibre blending eyelet fabric is covered on the 3rd filter course and forms composite bed with blancher flatiron.
The utility model can filter more than 0.03 micron particle diameter, good filtration effect.
The utility model adds chemical fibre blending eyelet fabric, thus adds pullling intensity and filtering rank of filter cotton.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or the conversion of equivalent flow process or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
In sum, the advantage that a kind of composite bed described in the utility model successively encrypts environmental protection filter cotton is, good filtration effect, and the power of pullling that can bear is large, and the life-span is long simultaneously.
