Description
Technical field
The utility model relates to a kind of air filter, relates in particular to a kind of bag filter.
Background technology
Air cleaner is widely used in the industries such as iron and steel, electronics, chemical industry, automobile, environmental protection and electric power, is that centrifugal compressor filters best inlet air filtration equipment, and various air-conditioning system dedusting oil removing filter plant.Therefore, air cleaner is to guarantee suitable room air, create clean production run environment or prevent that the aspects such as dangerous substance leakage from all playing vital effect.
Large, the empty dust quantity in windward side is large, the low best medium effeciency filter at present that has been considered to of wind speed because it has for bag filter, and middle effect bag filter comprises outside framework and the filter bag being fixedly connected with outside framework.Filter bag a kind of synthetic fibers or the glass fibres of adopting in existing bag filter are made more, and adsorption efficiency is low, poor filtration effect, and intensity is low, is unfavorable for the filter bag raising in service life.In addition, existing bag filter outside framework mostly is galvanized iron and adopts welding manner connection to make, and not only weight is large, and easily brings more weld defect, causes weld intensity low, affects filter whole service life.
Utility model content
The purpose of this utility model is to overcome the defect that prior art exists, and provides a kind of good filtration effect, the bag filter that filter bag intensity is high.
The technical scheme that realizes the utility model object is: a kind of bag filter, comprises square frame and the filter bag being fixedly connected with housing; Described filter bag material is made up of sandwich construction, comprises outer field polyester backbone layer and at least one deck fusion spray cloth filter course between polyester backbone layer; Described housing has aluminium alloy one-step die casting, and housing inside is provided with many reinforcements; Filter bag also has multiple, and filter bag sack is provided with fluid sealant, and is fixedly installed on housing and reinforcement by fluid sealant.
Technique scheme, described filter bag has four layers, comprises the two-layer fusion spray cloth filter course that middle part is combined with each other by PUR and bonds at the polyester backbone layer in two fusion spray cloth filter course outsides by PUR.
Technique scheme, 3～7 of described reinforcements, filter bag has 4～8.
Technique scheme, described reinforcement has 5, and filter bag has 6.
Technique scheme, described filter bag length is 300～600mm.
Adopt after technique scheme, the utlity model has following positive effect:
(1) the utility model filter bag is made after compound by multiple layers of different materials, and the polyester backbone layer of good permeability is positioned at outside, can play protection supporting role to inner filter course; Inner fusion spray cloth filter course, at least by one deck, can be set up the filter course number of plies or material according to actual conditions, not only improves filter efficiency, and reach best clean-up effect, and can make filtering material there is higher intensity, thus the service life of prolongation filter core;
(2) the utility model fusion spray cloth is made up of two-layer, two-layerly selects different materials also can select identical material, can make the space between two-layer fiber cloth overlapped, dwindles aperture diameter, plays the barrier effect good to granule; Fusion spray cloth, after Electrostatic Treatment, can make its surface with electrostatic charge in addition, thereby increases substantially the adsorption efficiency to particle, improves clean-up effect;
(3) the utility model adopts the aluminum alloy outer frame of integrally casting moulding, there is good corrosion resistance, and can avoid being welded to connect the weld defect bringing, affect the intensity of housing, thereby improve its service life, and aluminum alloy outer frame can reduce the weight of filter greatly, be convenient to carrying and install; Many the reinforcements that housing inside is provided with can improve the intensity of framework, also can play fixation to filter bag, prevent that the suffered wind-force of filter bag is excessive, and the filter bag and the housing that cause come off;
(4) the utility model reinforcement and filter bag quantity all can be set according to practical application place, thereby can meet different clients' diversified demand.
(5) the utility model novel structure, volume is small and exquisite, easy and simple to handle, and energy-conservation, efficient, and good airproof performance can be widely used in the filter plant of every profession and trade.

Detailed description of the invention
(embodiment 1)
See Fig. 1 to Fig. 4, the utlity model has square frame 1 and the filter bag 2 being fixedly connected with housing 1; Filter bag 2 materials are made up of sandwich construction, comprise outer field polyester backbone layer 21 and at least one deck fusion spray cloth filter course 22 between polyester backbone layer 21.The outer field polyester backbone layer 21 of the utility model can ensure that filter bag 2 is reverse V-shaped, makes it have enough deflections, increases Rong Shengliang, and while preventing that wind speed is excessive, filter bag 2 is out of shape, and in the middle of causing, two filter bags 2 fit together; When wind speed is too small, prevent that filter bag 2 deflections are inadequate, the bag wall of same filter bag 2 both sides fits together, and both of these case all can cause resistance increment, and filter bag performance can not be given full play to, and affects filter efficiency.
Preferably, the present embodiment filter bag 2 has four layers, comprises that two-layer that middle part is combined with each other by PUR bonds at the polyester backbone layer 21 in two fusion spray cloth filter course 22 outsides through the fusion spray cloth filter course 22 of Electrostatic Treatment with by PUR.
Preferably, housing 1 is by aluminium alloy one-step die casting, and housing 1 inside is provided with many reinforcements 3; Filter bag 2 also has multiple, and filter bag 2 sacks are provided with fluid sealant, and is fixedly installed on housing 1 and reinforcement 3 by fluid sealant.Reinforcement 3 quantity can be designed to 3～7 as required, and corresponding filter bag 2 is 4～8.The present embodiment reinforcement 3 has 5, and filter bag 2 has 6, and square frame 1 length of side is 595mm, and filter bag 2 length can be designed between 300～600mm according to actual needs, and the present embodiment filter bag 2 length are 500mm.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
