Detailed description of the invention
Below by embodiment, in conjunction with accompanying drawing, embodiment of the present utility model is further detailed.
As shown in Figures 1 to 4, embodiment of the present utility model provides a kind of novel pleated filter cylinder, including top cover 1, cylinder 2
With bottom 3, being provided with through hole in top cover 1, the two ends of cylinder 2 are respectively fixedly connected with on top cover 1 and bottom 3；Cylinder 2 is tied in pleated
Structure；On the cross section of cylinder 2, the outward flange of cylinder 2 and inward flange lay respectively on an ellipse；The surface of cylinder 2 was provided with
Filter medium layer, filtering medium layer is pleated structure.
The filter cylinder of said structure, the outward flange of cylinder 2 and inward flange lay respectively on an ellipse.It is to say, cylinder 2 sections
Face is the ellipse of hollow.Compared with identical floor space and the most equal circular pleated filter cylinder, the cylinder 2 of the present embodiment increases
Big surface area, thus filter area increases.Which improves filter efficiency.Air-flow is in cylinder 1 side inflow cylinder 1
Side, after the impurity in filtering medium layer filtered airflow, enters inside cylinder 1.Owing to cylinder 2 cross section is the ellipse of hollow
Shape, and cylinder 2 is in pleated structure, filter area is big, thus improves filter efficiency.
Preferably, as it is shown in figure 5, described filtering medium layer include being sequentially connected with thick effect filtering medium layer 4,
Activated carbon fiber layers 5 and high-efficiency filtration media layer 6, and slightly effect filter medium 4 is positioned at side, windward side.Airflow passes filtering medium layer
Time, at first through thick effect filtering medium layer 4, it is then passed through activated carbon fiber layers 5, eventually passes high-efficiency filtration media layer 6.Preferably
, thick effect filtering medium layer 4 is made up of chinlon filter screen.Chinlon filter screen has that poly-dirt rate is high, initial resistance is low, anti-dust performance is strong, resistance to
Mill and the feature performance benefit of length in service life.Preferably, high-efficiency filtration media layer 6 is by PP(polypropylene) cotton makes.PP cotton has filtration
Precision is high, service life length and the feature performance benefit of low cost.Air-flow first passes through thick effect filtering medium layer 4, contaminant particle energy quilt
Rough stops；Again through activated carbon fiber layers 5, this layer can adsorb contaminant particle efficiently, it is possible to removes in air
Abnormal flavour and volatile organic matter (such as formaldehyde and benzene etc.)；Eventually pass high-efficiency filtration media layer 6, carbon particle and tiny can be prevented
Pollutant flow out so that filter efficiency is greatly improved.Through three layers of media filtration, improve filter effect.
Preferably, described activated carbon fiber layers 5 is prepared by chemical vapour deposition technique.Chemical vapour deposition technique
(being called for short CVD) is that reacting substance issues biochemical reaction at gaseous condition, generates solid matter and is deposited on the solid matrix of heating
Surface, and then the Technology of prepared solid material, chemical vapour deposition technique is divided into again flow method and collective's method two kinds, flow method
It is more convenient for raised growth carbon nano-fiber.The activated carbon fiber layers 5 obtained by the flow method in chemical vapour deposition technique can be had
Effect removes the abnormal flavour in air and the harmfulness volatile organic matter such as formaldehyde, benzene.Meanwhile, activated carbon can also tiny of efficient absorption
Grain thing, improves the filter efficiency of filter medium.
Preferably, the outward flange of described cylinder 2 is cambered surface.The outward flange of cylinder 2 is arranged in cambered surface, permissible
Increase filter area further.
Preferably, the described transverse at cylinder 2 outward flange place and the ratio of short axle and cylinder 2 inward flange institute
Oval major axis equal with the ratio of short axle.So on the one hand, it is easy to make, is on the other hand easier to deashing.
Preferably, described oval major axis is 1.1 ~ 1.7 with the ratio of short axle.By arranging the major axis of ellipse
With the ratio of short axle in the range of reasonably so that the stability of the cylinder 2 made is more preferable, and filter area is bigger.Equally, in order to make
The cylinder that must make has good filter effect, and the pleat number of described cylinder 2 is 45 ~ 100.Pleat number is too much, can give and make band
It is inconvenient to come.Pleat number is very few, is unfavorable for improving filter efficiency.
In view of reality application, as conventional physical dimension, the height of described cylinder 2 is 350 ~ 400mm, and pleat is a height of
35 ~ 45mm, pleat spacing is 3.5 ~ 5.5mm.Described transverse is 110 ~ 340mm, and short axle is 100 ~ 200mm.Certainly basis
Actual application scenario, can be with the above-mentioned numerical range of Reasonable adjustment, even beyond above-mentioned numerical range.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.Those skilled in the art
It should be appreciated that this utility model is not limited by above-mentioned specific embodiment, the description in above-mentioned specific embodiment and description is only
It is to further illustrate principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this practicality
Novel also have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This reality
Define by claims and equivalent thereof by novel claimed scope.
