Detailed description of the invention
Refer to Fig. 1 to Fig. 5, the utility model labyrinth type dust removal filter, comprise an inner housing 1 for cavity 11, described housing 1 is provided be communicated with cavity 11 air inlet 12, air outlet 13 and centrum 2.Described air inlet 12 is arranged on housing 1 sidewall, and described air outlet 13 is arranged on housing 1 top, and described centrum 2 to be arranged on bottom housing 1 and to be tightly connected with housing 1, is provided with dust collecting box 21 below centrum 2.Labyrinth type dedusting assembly 3 is provided with, for filter bag dirt air in housing 1 between described air inlet 12 and air outlet 13.
Described labyrinth type dedusting assembly 3 comprises the first filter 31, dust guiding tube 32 and center mozzle 33.Described first filter 31 sidewall is surrounded with multiple through hole, and particularly, this through hole is fish scale hole 4.As shown in Figure 5, fish scale hole 4 opening is towards consistent with whirlwind direction, and flap 41 protrusion direction in fish scale hole 4 is consistent with the direction of whirlwind.Band dirt high pressure whirlwind when deduster internal rotating, dust rub projection flap 41 after kinetic energy reduce, just can drop in centrum 2.The blast loss of 4 pairs, wide-aperture fish scale hole is very little.
First filter 31 is being just the enclosed construction 311 without fish scale hole 4 to the sidewall of air inlet 12, on the left of enclosed construction 311 and below is provided with protruding L shape deflector 312, after making band dirt high-pressure blast enter cavity 11, under the stop and guiding of deflector 312, form whirlwind in cavity 11 towards an azimuthal rotational motion, the centrum 2 of bottom can guide whirlwind to be rotated down.
Bottom first filter 31, sidewall is also provided with outward extending dust-leading board 313, and dust can fall into bottom centrum 2 along dust-leading board 313.
Described dust guiding tube 32 is by top air dam 321, and middle part dust removal unit 322 and lower guide dirt portion 323 are connected in sequence.Described air dam 321 to be arranged in the first filter 31 and to be provided with the second air inlet 3211, second air inlet 3211 opening towards consistent with cyclonic motion direction.Second air inlet 3211 is provided with protruding 3212, and protruding 3212 directions are also consistent with cyclonic motion direction.The described dirt portion 323 that leads to be arranged in housing 1 and to be communicated with dust collecting box 21 by pipeline 22.The buckle structure connected with the rotatory sealing be connected bottom the first filter 31 is provided with in the middle part of dust guiding tube 32, can easy disassembly.
The described dirt portion 323 that leads is a cone-shaped cavity, described cone-shaped cavity sealed bottom, and its underpart to be stretched in pipeline 22 and its sidewall is provided with dust mouth 3231.
Described center mozzle 33 is arranged in dust guiding tube 32, and its shape is the cylindrical shape of sealed bottom, and bottom is coniform.Center mozzle 33 sidewall is surrounded with multiple through hole, and particularly, this through hole is fish scale hole 4.As shown in Figure 5, fish scale hole 4 opening is towards consistent with whirlwind direction, and flap 41 protrusion direction in fish scale hole 4 is consistent with the direction of whirlwind.Center mozzle 33 is for third time time filter bag dirt high-pressure blast.Center mozzle 33 top is communicated with air outlet 13, and the high-pressure blast after filtration is discharged.Center mozzle 33 top is provided with the structure sealing clamping with the first filter top, with easy disassembly.
Described air outlet 13 is provided with screen pack, with intensive filtration effect.
The utility model is work like this: band dirt high pressure gas enters after cavity 1 from air inlet 12 and rotate formation whirlwind in cavity 1 inner high speed under the guiding of deflector 312, dust constantly rub the first filter 31 projection flap 41 after kinetic energy reduce gradually, owing to narrowing toward centrum position revolution space, dust density in whirlwind increases, mutual frictional impact, kinetic energy reduces and forms large particle, finally falls under gravity in centrum 2.
It is inner that high pressure gas after first time filters enters the first filter 31 from fish scale hole 4, still rotates in cyclone type, then rotates around the air dam on dust guiding tube 32 top and the dust removal unit at middle part, and after dust friction dust guiding tube 32 tube wall, kinetic energy falls after reducing.The projection 3212 of the second air inlet 3211 can prevent band dust devil from directly entering in it, and whirlwind needs to walk around protruding 3212 and just can enter.It is inner that whirlwind enters dust guiding tube 32, and dust falls into dust collecting box after rubbing with the flap 41 of center mozzle 33 projection.Filter the whirlwind after by purification discharged from air outlet 13 by fish scale hole.Air outlet 13 place is also provided with screen pack, improves filtering accuracy further.
Labyrinth type dust removal filter of the present utility model has triple filter parts, wherein the first filter 31 and center mozzle 33 adopt fish scale hole 4 to filter band dirt gases at high pressure, gas with dust constantly rotates and makes dust and continuous friction of flap 41 reduce kinetic energy in filter, finally fall into centrum 2 and dust collecting box 21, and gas with dust needs to walk around flap 41, can not directly enter in fish scale hole 4, flap 41 serves an effect postponing and stop, achieve filter effect more better than general cyclone filter, fish scale hole 4 adopts large aperture, too high attenuation can not be caused to blast, have matched the follow-up high blast filter re-used well, structure is simple, with low cost, easy to maintenance.
The utility model is not limited to following embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
