Specific embodiment

In order to make those skilled in the art more fully understand the scheme of the utility model embodiment, with reference to the accompanying drawing and Embodiment is described in further detail the utility model embodiment.

Referring to Fig.1 ~ 5, the purifying and dedusting device of a kind of flame cutting machine, including cylindrical housings 9,9 one end of shell are fixed Air inlet port 7 is installed, and ash discharging hole 8 is distributed in 7 lower part of air inlet port, 9 other end of shell passes through connecting shaft 13 and driving motor 12 connections, below shell 9 distribution there are four the ash discharging hole (8-1,8-2,8-3,8-4) inside corresponding housing, on housing wall along There are three fixed grit card slots 10 for axial distribution, and fixed grit card slot is between four ash discharging holes (8-1,8-2,8-3,8-4) two Between two, exhaust pipe 11 is distributed in 9 top one end of shell；

It is dedusting chamber 17 inside shell 9, dedusting chamber is divided into four regions by three fixed grits (16-1,16-2,16-3), Four ash discharging holes (8-1,8-2,8-3,8-4) on shell correspond to four regions of dedusting chamber 17, and flue gas passes through four The dust of different-grain diameter is discharged via different ash discharging holes (8-1,8-2,8-3,8-4) behind region；It is distributed in each dedusting region Have a rotary screen 19 connected by connecting shaft 13, the wire side porosity of corresponding rotary screen 19 with flue gas walking path gradually Reduce, three fixed grits (16-1,16-2,16-3) are successively subtracted by air inlet port 7 to 11 path upper screen cloth porosity of exhaust pipe It is small, and three fixed grit (16-1,16-2,16-3) wire side porositys correspond to the porosity of adjacent rotary screen 1.

Specifically, the spiral board 15 connected by connecting shaft 13 is distributed with inside air inlet port 7, on 9 wall of end housing It is distributed with through 21 support sleeve 22 of supporting rib, forms fan-shaped cavity between supporting rib 21, pass through for the flue gas of extraction, connecting shaft 13 It is connect across axle sleeve 22 with spiral board 15, spiral board 15 is arranged inside air inlet port 7, can provide bigger flue gas and attract Power, while being thrown on the wall surface of air inlet port 7 then by the bulky grain metal oxide after spiral board 15 through centrifugal action It slides in ash discharging hole 8, the air-flow after spiral board 15 is not due to having power resources, with rotary screen 19 and fixed grit 16 obstruction speed gradually reduces, and after four separation dedustings, gas is discharged through exhaust pipe 11.

Specifically, rotary screen 19 is including axle sleeve 19-1 and is located at six screen stencil sheet 19-2 of axle sleeve, and screen stencil sheet 19-2 Angle is 60 °, and rotary screen 19 is connect by axle sleeve 19-1 with connecting shaft 13, with the rotation of driving motor 12, along dedusting chamber 17 radial rotaries hit the particle that particle size is greater than sieve mesh down, and cooperation fixed grit 16 carries out the dust of one's respective area Removal enters next dedusting region after the flue gas in the region removes big partial size dust granule and carries out purifying and dedusting.

Specifically, fixed grit includes circular screen wire side and the fixation auricle 14 on circumference, and on circular screen wire side U-shaped notch is distributed with, it can be by changing since circular screen wire side is flexible setting by connecting shaft 13 when U-shaped notch is for installation After deformation shape facilitates installation, fixed grit 16 to stick into shell sieve card slot 10, fixed auricle 14 passes through bolt and sieve card slot 10 It is fixedly connected.

Referring to Fig. 6 ~ 8, a kind of smoke extraction system of flame cutting machine, including the support steel framework 4, fixedly fixed on the ground I-steel seat 6 on face and as steel grid 3 on support steel framework, 6 groove of I-steel seat, which is hidden, is distributed with rectangular flue 5, cutter rail 2 is fixedly mounted on I-steel seat 6, and flame cutting machine 1 is slidably mounted on cutter rail 2, fume pipe A series of bleeding point 5-1 are distributed with above in road 5, and the matched rubber with 5 upper surface of flue is equipped with above bleeding point 5-1 Pad 18, being adsorbed on bleeding point 5-1 tightly of rubber pad 18 under the draft effect of purifying and dedusting device, avoids generating fume pipe 5 gas leakage of road；And 1 pedestal lower part of flame cutting machine is matched is equipped with an idler wheel 20, idler wheel 20 is as flue 5 and rubber pad Between 18, with the movement of flame cutting machine, the synchronous bleeding point 5-1 for opening flue is realized and is extracted to the synchronous of flue gas, Flue 5 connect by variable diameter air hose with air inlet port 7, the flue gas generated after cutting via after flue 7 into purifying Dust-extraction unit is dusted operation.

Working principle:

Firstly, opening flame cutting machine 1, flame cutting machine 1 slides on cutter rail 2 therewith, and carries out to workpiece Cutting operation, and generate flue gas；Secondly, the idler wheel 20 for being located at 1 lower section of flame cutting machine is synchronous to open flue bleeding point 5- 1, it is extracted to flue gas is generated in 1 cutting process of flame cutting machine；Again, flue gas passes through the spiral board of purifying and dedusting device 15, large dust particle is fallen into ash discharging hole 8, and the flue gas of preliminary dust removal enters in dedusting chamber 17, in the rotation of corresponding porosity Under the cooperation of sieve 19 and fixed grit 16, the dust particles of appropriate level are removed；Finally, flue gas by dedusting enter it is next After grade dedusting region is until complete level Four dedusting, tail gas is discharged via exhaust pipe 11.It should be noted that the purifying and dedusting device It is equally applicable to other cutting technique fields and is not limited solely to gas flame cuttiug technical field.

Mode described above describes the preferred embodiment of the utility model, undoubtedly, for the common of this field Technical staff can be with a variety of different modes to described without departing from the spirit and scope of the utility model Embodiment be modified.
