Abstract
The utility model relates to an air filtering device, and particularly relates to a high-efficiency filter. The high-efficiency filter comprises a filter element and a side frame which is positioned outside the filter element and identical with the filter element in shape; protective supporting nets are arranged on the upper side and the lower side of the side frame and are latticed, and an anticorrosive layer is arranged on the surface of each protective supporting net. The protective supporting nets arranged on the upper side and the lower side of the side frame can prevent the filter element from being subjected to large wind force and generating deformation to further influence the filtering efficiency; through latticed filter screens, the strength of the supporting nets can be enhanced, and further the overall service life can be prolonged; the surfaces of the supporting nets are galvanized or adopts ionic nitriding or QPQ salt bath nitriding, so that a nitriding layer with certain thickness is formed on the surfaces of the supporting nets, therefore the corrosion resistance of the supporting nets can be greatly increased, and the service lives of the supporting nets can be prolonged.
Description
Technical field
The utility model relates to a kind of air filter, relates in particular to a kind of high efficiency particulate air filter.
Background technology
Along with the raising of people's environmental consciousness, also more and more higher to the requirement of air purity, therefore various air purifiers also arise at the historic moment, and according to the air cleaning requirement of different indoor environments, filter is divided into thick effect, middle effect and efficient conventionally.Traditional filter mostly has been dividing plate air cleaner, mostly adopt the art paper of two-sided gluing to make demarcation strip, to prevent that demarcation strip is shunk by the impact that cold, hot, dry is wet, thereby distribute particulate, and when humiture changes, thisly every cardboard, may have larger particles and distribute, thereby cause workshop cleanliness factor test failure.
At present; on market, engendered various without dividing plate high efficiency particulate air filter; and existingly without baffle filter structure, comprise housing and filter core more; the protection structure of shortage to filter core; cause filter core when large or service time is longer at air quantity, easily to produce distortion; thereby affect the filter efficiency of filter core, when serious, also can cause filter core premature failure, cause the reduction in service life.Even if some filter two sides has protective device, but because filter is exposed in pickling gas for a long time, can produce larger corrosion to protective device, cause protective device to damage too early, affect the service life of monolithic filter.
Utility model content
The purpose of this utility model is to overcome the defect that prior art exists, and a kind of long service life is provided, and filter efficiency is high, lightweight, the convenient high efficiency particulate air filter of installing.
The technical scheme that realizes the utility model object is: a kind of high efficiency particulate air filter, has filter core and be positioned at filter core outside and the frame identical with filter core shape; Described frame upper and lower surface is equipped with protection supporting network, and described protection supporting network is latticed, and protection supporting network surface is provided with anticorrosive coat.
Technique scheme, described anticorrosive coat is zinc coat or nitration case.
Technique scheme, described frame is rectangle aluminum alloy frame, and described frame is long is 300mm, and wide is 150mm, and height is 45mm.
Technique scheme, described filter core is for by material for core, the folding after repeatedly repeating folding forming, folding is high all identical with folding spacing.
Technique scheme, described material for core is comprised of multilayer, comprises at least polyester backbone layer of one deck fusion spray cloth filter course and fusion spray cloth filter course outside.
Technique scheme, described material for core forms by four layers, comprises respectively outermost two layers polyester casing play and middle two-layer fusion spray cloth filter course.
Technique scheme, described fusion spray cloth filter course material is the PETG through Electrostatic Treatment, described polyester backbone layer material is Kynoar.
Technique scheme, described material for core thickness is 1～2mm.
Adopt after technique scheme, the utlity model has following positive effect:
(1) the protection supporting network that the utility model frame upper and lower surface is provided with, can prevent that the wind-force that filter core is subject to from deforming more greatly, affects filter efficiency; And screen pack adopts latticed, can improve supporting network intensity, thereby extend whole service life; Zinc-plated processing is carried out on supporting network surface, or adopts ionic nitriding or QPQ salt-bath nitriding, makes its surface form certain thickness nitration case, can greatly improve the corrosion resistance of supporting network, thereby improve the service life of supporting network;
(2) the utility model adopts the aluminum alloy frame that density is low, corrosion resistance good and intensity is high, not only can greatly reduce the weight of filter, is convenient to carrying and installs, and under equal conditions can promote air quantity, thereby improving air purification effect; And frame size is also conventional filter frame half, thereby further reduced the weight of filter, promoted air quantity, and can save material; In addition each size reduce also can reduce filter resistance, avoid energy waste, energy-conserving and environment-protective;
(3) the utility model adopts excellent material as filter core, and multilayer material is mutually compound, not only can improve filter efficiency, reaches best clean-up effect, and can make filtering material have higher intensity, thereby extends the service life of filter core.

In figure 1, filter core; 11, filter course, 12, polyester backbone layer; 2, frame; 3, protection supporting network.
The specific embodiment
(embodiment 1)
See Fig. 1 to Fig. 4, the utlity model has filter core 1 and be positioned at filter core 1 outside and the frame 2 identical with filter core 1 shape; Frame 2 upper and lower surfaces are equipped with protection supporting network 3, and protection supporting network 3 is latticed, and protection supporting network 3 surfaces are provided with anticorrosive coat.Anticorrosive coat can be the zinc coat forming after plating zinc on surface, also can be the nitration case forming after surfaces nitrided, and these two kinds of anticorrosive coats all have good corrosion resistance in sour corrosion gaseous environment, thereby can increase substantially the service life of protection supporting network 3.
Preferably, the utility model frame 2 is rectangle aluminum alloy frame 2, and the long L of frame 2 is 300mm, and wide W is 150mm, and high H is 45mm, is only half of conventional filter size, can reduce whole weight, is convenient to install and carrying; Undersized filter core and frame all have higher intensity in addition, under equal conditions, can promote air quantity, thereby improve filter efficiency.
