Description

Pulsed blowback bag dust collector
Technical field
The utility model relates to technical field of industrial dust removal, relates in particular to a kind of pulsed blowback bag dust collector.
Background technology
It is little to there is process intake in the back-blowing bag-type dust collector that current industrial dedusting device on the market adopts, the problem of ash-removal effect difference.Although improve the admission pressure of disposable press-in and minimizing to blow the cycle and can promote ash-removal effect, be easy to cause the tired and wearing and tearing of parts to reduce parts service life like this.And existing product needs when clearing up and changing filter bag to shut down, and is not suitable for not stopping work for a long time the occasion done.
Utility model content
For solving the problem, the utility model provides a kind of pulsed blowback bag dust collector.
Concrete technical scheme of the present utility model is as follows:
A kind of pulsed blowback bag dust collector, comprises casing, air-introduced machine, ash bucket, high pressure gas bag, pulse valve and air jet pipe; Described ash bucket is positioned at bottom half, and described air-introduced machine is positioned at casing top; Described high pressure gas bag connects air jet pipe, and described pulse valve, between high pressure gas bag and air jet pipe, when pulse valve is opened, conducting between high pressure gas bag and air jet pipe, to cut out when pulse valve, closed between high pressure gas bag and air jet pipe; Being provided with multiple filter chamber arranged in parallel in described casing, described filter chamber bottom opening, comprising filter bag and the skeleton for supporting filter bag; Described filter chamber is positioned at directly over ash bucket, and described air jet pipe is connected to the top of filter chamber.
By adopting this technological means: in practice, pulsed blowback bag dust collector is fixed on directly over the feed bin of mixer, start air-introduced machine, the air stream containing dust in feed bin is made to enter in casing by ash bucket under the effect of air-introduced machine, these air containing dust flow to into filter chamber, be deposited on the inner surface of filter bag by inertial collision and sieving, the air of filtering dust then continues to rise through filter bag and arrives air-introduced machine, is entered in air by air-introduced machine.When after the dust that filter bag deposited some, open pulse valve, make the compressed air in high pressure gas bag enter air jet pipe, and be ejected in filter chamber through air jet pipe, make the dust that filter bag inner surface deposits come off under the jet-stream wind effect of air jet pipe and fall into ash bucket, reach the object of deashing.Because each filter chamber is in the state of working alone, therefore reduce the air consumption of high pressure gas bag, extend the winding-up cycle simultaneously, correspondingly reduce the degree of fatigue of filter bag and pulse valve, extend the service life of parts.
For reducing the friction between skeleton and filter bag, improve the service life of filter bag: preferably, in above-mentioned pulsed blowback bag dust collector, described skeleton cross section is polygonal.
It is further preferred that in above-mentioned pulsed blowback bag dust collector, described filter chamber also comprises elastic piston ring, described elastic piston ring is nested on skeleton, holds out against in filter bag inner surface.
By adopting this technological means: the elastic telescopic performance utilizing elastic piston ring, make the connection of filter bag and keel more solid and reliable, the better tightness inside and outside casing.
Further preferably, pulsed blowback bag dust collector also comprises pulse valve controller, and described pulse valve controller connects pulse valve, work for control impuls valve.The tapered tubular construction of described ash bucket, one end is the big uncork other end is little opening; Described ash bucket big uncork one end is connected to bottom half.Described filter chamber top is provided with Venturi tube.
By adopting this technological means: dust enters the process of casing from ash bucket, flow cross-sectional is long-pending to be expanded, and causes the flow velocity of air-flow to reduce, and the bulky grain in air-flow, greatly density dust are fallen under gravity; And the little grit at the bottom of fine size, density evenly enters also disperse in casing.Avoiding big dust particle sticks on filter screen, extends the cycle of reverse gas cleaning further; Utilize the Venturi tube of filter chamber top, make the compressed air being entered filter chamber by air jet pipe under Venturi effect effect, form one several times volume induced draft, make ash-removal effect better.
Compared with prior art, the utility model structure is simple, is easy to realize.Good purification, extends the service life of parts, runs safety and reliability.

Detailed description of the invention
In order to be illustrated more clearly in the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further described.
The utility model embodiment 1 as shown in Figure 1-2:
A kind of pulsed blowback bag dust collector, comprises casing 1, air-introduced machine 2, ash bucket 3, high pressure gas bag 4, pulse valve 5 and air jet pipe 6 and pulse valve controller 8.Described air-introduced machine 2 is positioned at the top of casing 1; The tapered tubular construction of described ash bucket 3, one end is the big uncork other end is little opening; Described ash bucket 3 big uncork one end is connected to bottom casing 1.Described high pressure gas bag 4 connects air jet pipe 6, and described pulse valve 5, between high pressure gas bag 4 and air jet pipe 6, when pulse valve 5 is opened, conducting between high pressure gas bag 4 and air jet pipe 6, to cut out when pulse valve 5, closes between high pressure gas bag 4 and air jet pipe 6; Be provided with multiple filter chamber 7 arranged in parallel in described casing 1, described filter chamber 7 bottom opening, top are provided with Venturi tube 74; Filter chamber 7 comprises filter bag 71, skeleton 72 and elastic piston ring 73, and described skeleton 72 cross section is in quadrangle, for supporting filter bag 71.Elastic piston ring 73 is nested on skeleton 72, holds out against in filter bag 71 inner surface.Described filter chamber 7 is positioned at directly over ash bucket, and described air jet pipe 6 is connected to the top of filter chamber 7.
In practice: be fixed on directly over mixer feed bin by above-mentioned pulsed blowback bag dust collector, start air-introduced machine 2, the air stream containing dust in feed bin is entered in casing 1 by ash bucket 3 under the effect of air-introduced machine 2.Dust enters the process of casing 1 from ash bucket 3, because the tapered tube configuration of ash bucket 3, flow cross-sectional is long-pending to be expanded, and causes the flow velocity of air-flow to reduce, and the bulky grain in air-flow, greatly density dust are fallen under gravity; And the little grit at the bottom of fine size, density evenly enters also disperse in casing 1.Air containing the little grit at the bottom of these fine sizes, density flows in filter chamber 7, the inner surface of filter bag 71 is deposited on by inertial collision and sieving, the air of filtering dust then continues to rise through filter bag 71 and arrives air-introduced machine 2, is entered in air by air-introduced machine 2.When after the dust that filter bag 71 deposited some, pulse valve 5 is opened by pulse valve controller 8, the compressed air in high pressure gas bag 4 is made to enter top, filter chamber 7 through air jet pipe 6, when the Venturi tube 74 through top, described filter chamber 7, the induced draft of one several times volume is formed under Venturi effect effect, make the dust that filter bag 71 inner surface deposits come off under the percussion of induced draft and fall into ash bucket 3, reach the object of deashing.
The above; be only specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; the technical staff of any skilled is in technical scope disclosed in the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with the protection domain of claims.
