The novel dust remover belongs to the environmental protection dust removal field and is applied to machine work and all dust work stations, in particular to being used to purify air with a plenty of sand, for example a sand blasting operation. The novel dust remover has the advantages of perfect structure, long service life and high dust removal efficiency which reaches as high as 99.99 percent.
Description
A kind of novel deduster, form by filter chamber, aerodynamic separator, filter core, compressed air blowback mouth, flue-dust retainer etc., belong to environmental protection dedusting technology field, be applicable to machining and various dust work point, the purified treatment that is particularly useful for dust-containing air in the surface sand-blasting operation before the steel component application, compact conformation, rationally distributed, long service life, efficiency of dust collection height.
The dust laden air that produces in industrial production is if directly enter atmosphere, with serious environment pollution, along with industrial continuous development, environmental protection requirement is also improved day by day, in the prior art, to the purified treatment of dust laden air, generally adopt cyclonic separation to add the mode of cloth bag filtration.Enter the cyclonic separation section as dust laden air from the air inlet of deduster, the dust of larger particles motional inertia and gravity by self in segregation section sinks in the dust collection on the way, and thinner dust is by flat cloth bag filtration.Cleaned air passes enters atmosphere through exhaust duct, be arrested in the dust of flat cloth bag outer surface, in cloth bag, outwards carry out blowback wind in order termly to remove the laying dust on the cloth bag outer surface, deashing process is finished by a cover automatic program control, the dust of removing also falls into dust collection, is discharged by unloading valve.Disclose above-mentioned technical information in the YZB unit-combination type flat bag filter product sample by Joint Venture Yinyan Environmental Protection Equipment Engineering Co., Ltd., B's printing, the progress of this deduster is to make the filter cloth of cloth bag can be according to the temperature apolegamy of dust laden air, during as≤120 ° with polyester pin felt, 140～150 ℃ the time with 208 terylene, use glass fibre 200～250 ℃ the time, but the equal series fiber fabric of filter cloth, its gap is 300 μ m, grit less than 300 μ m embeds the gap easily, cloth bag is stopped up, increased the deashing difficulty.And cloth bag do not have rigidity, and repeated deformation in deashing damages easily, and service life is shorter.Adopt the cyclonic separation mode in addition, airflow direction changes mild, is unfavorable for that grit leans on its own inertial separated from the gas, thereby has increased the burden of cloth bag, has shortened cleaning cycle.Because the breakage of cloth bag has been quickened in frequent deashing operation again.
The purpose of this utility model provides that a kind of more reasonable structure, efficiency of dust collection are higher, longer service life, novel deduster that volume is littler.
For achieving the above object, the utility model deduster is made up of filter chamber, aerodynamic separator, filter core, flue-dust retainer, compressed air blowback mouth, pure air passage etc., aerodynamic separator is vertically mounted on a side of filter chamber, filter core level or opposite side vertical, that tilt to be installed in the filter chamber.An aerodynamic separator and a filter core are set in the filter chamber at least, connect a dust laden air import and a pure air outlet at least.Flue-dust retainer is installed in the bottom of filter chamber, compressed air blowback mouth is installed in the pure air passage and aims at the center of filter core openend, it is characterized in that this aerodynamic separator is a cone that the cross section is a rectangle, constitute and to the venetian blind type member of under shed by grizzly bar, its minor face is two conical plates, the two ends of grizzly bar are separately fixed on two limits of two conical plates, constitute the shutter form under shed; This filter core is a hollow cylinder, constitutes barrel by filter course, and this barrel is the accordion that composite radially is folded into, and is covered with to prevent the wire catch net that is out of shape on surfaces externally and internally, and scribbles the fibrage of ultra-fine ultra-thin submicron order diameter.
That described novel deduster, the cone cross section of its aerodynamic separator also can be is square, triangle, trapezoidal, polygon, circle, ellipse.
Described novel deduster, the vertical section of its filter core are circular, oval, square, rectangle, triangle, polygon.
After adopting said structure, because the cone that is rectangle that aerodynamic separator is a cross section, the venetian blind type member that constitutes by grizzly bar, when walking around grizzly bar, air-flow swerves, and grit is because its own inertial, continue to move downward by gravity, the grit that the overwhelming majority in the air-flow is thicker is settled down in the flue-dust retainer, and the trickle grit of fraction is through filter element filtering, alleviated the burden of filter core widely, again owing to adopted the filter core of the special construction of making by composite, can capture the fine grit of 0.5 μ m, efficiency of dust collection reaches 99.99%.The fiber that scribbles the ultra-fine thin submicron order diameter of one deck because of cartridge surface becomes smooth, can not adhere to dust, more can not make dust be penetrated into filtering layer inside, the difficulty and the frequency of deashing operation have been reduced, and filter core has certain rigidity, be fixedly mounted on again in the filter chamber, can withstand the impact of reverse impulse air-flow in the deashing operation, thereby only produce slight deformation and do not influence and obtain higher efficiency of dust collection and long service life service life.
Because the barrel of filter core is the accordion that composite radially is folded into, filter area is big, and its volume only is equivalent to 1/3 of air quantity sack cleaner at the same level, and it is compact that structure becomes.
The utility model compared with prior art has following advantage:
1. owing to airflow direction changes the deficiency that influences separating effect gently, improved separating effect behind the employing aerodynamic separator when having overcome cyclonic separation in the prior art;
2. overcome flat cloth bag short deficiency in service life in the prior art, significantly improved efficiency of dust collection behind the employing filter core, prolonged service life.
3. overcome cloth pocket structure corrugationless in the prior art and made the less deficiency of unit volume filter area, compact conformation, the volume of this deduster are less, can save floor occupying area and installing space.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
