Description

A kind of dual filtering type dust removal filter

Technical field

The utility model relates to industrial dedusting equipment, particularly a kind of dual filtering type dust removal filter.

Background technology

At present, various dedusters use on a large scale in industrial circle. Cyclone dust removal is not affected by environment, simple in structure, occupies little space, and cost is lower, but its efficiency of dust collection is low; Dust removal by filtration efficiency of dust collection is high, but it is large to take up room, and resistance and power consumption are all larger, and equipment cost is higher. Band dirt air is after cyclone dust collectors dedusting, and dedusting precision is low, and weak effect conventionally also will use sack cleaner again to filter small dust granules and just can reach good dust removing effects. But cyclone dust collectors will use low blast just can have good dust removing effects, and sack cleaner will use high blast work, cannot mate well use between the two. And sack cleaner to certain working time just need change, consumptive material is costly.

Utility model content

The utility model is to overcome the shortcoming of prior art with not enough, a kind of high efficiency, high accuracy is provided and can not stops up and labyrinth type dust removal filter that use cost is lower.

The utility model is to realize by following technical scheme: a kind of dual filtering type dust removal filter, comprise an inner housing for cavity, on described housing, be respectively arranged with the air inlet, the air outlet that are communicated with cavity, described air inlet is arranged on housing sidewall, described air outlet is arranged on case top, and described housing bottom is provided with dust collecting box. Further, also comprise filter and center dust guiding tube, described filter bottom is communicated with dust collecting box, its sidewall is surrounded with multiple fish scales hole array, described filter is being just the enclosed construction without fish scale hole to the sidewall of air inlet, enclosed construction left side and below are provided with the L shaped deflector of projection, described filter bottom is provided with outward extending dust-leading board, described center mozzle is arranged in filter, it is shaped as sealed bottom cylindrical shape, its sidewall is surrounded with multiple fish scales hole, and mozzle top, described center is communicated with air outlet.

Further, the fish scale hole of described filter favours filter outer wall, and its opening direction is consistent with the gas with dust direction of motion, and the flap projection side in fish scale hole is consistent with the direction of gas with dust motion; The fish scale hole of described center mozzle favours center mozzle outer wall, and its opening direction is consistent with the gas with dust direction of motion, and the flap projection side in fish scale hole is consistent with the direction of gas with dust motion.

The utility model has double filtration parts, filter and center mozzle adopt fish scale hole to filter band dirt gases at high pressure, gas with dust in filter constantly rotation make dust and the flap reduction kinetic energy that constantly rubs, finally fall into centrum and dust collecting box, and gas with dust need to be walked around flap, can directly not enter in fish scale hole, obtain than the better filter effect of general cyclone filter, and employing large aperture, fish scale hole, can not cause too high attenuation to blast, mate well the follow-up high blast filter re-using, simple in structure, with low cost, easy to maintenance.

Detailed description of the invention

Refer to Fig. 1 to Fig. 4, the utility model labyrinth type dust removal filter, comprises an inner housing 1 for cavity 11, is provided with the air inlet 12, air outlet 13 and the centrum 2 that are communicated with cavity 11 on described housing 1. 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 is arranged on housing 1 bottom, and centrum 2 bottoms are provided with dust collecting box 21.

Also comprise filter 31He center mozzle 32. Described filter 31 is tubular, and sidewall is surrounded with multiple fish scales hole 4. As shown in Figure 4, fish scale hole 4 openings are towards consistent with whirlwind direction, and flap 41 protrusion direction in fish scale hole 4 are consistent with the direction of whirlwind. Band dirt high pressure whirlwind is in the time of deduster internal rotating, and the dust rear kinetic energy of protruding flap 41 that rubs reduces, and just can drop in centrum 2. Wide-aperture fish scale hole 4 is very little to blast loss.

Filter 31 is being just the enclosed construction 311 without fish scale hole 4 to the sidewall of air inlet 12, enclosed construction 311 left sides and below are provided with the L shaped deflector 312 of projection, make to be with dirt high-pressure blast to enter after cavity 11, interior towards a direction rotation motion formation whirlwind at cavity 11 under the stopping of deflector 312, the centrum 2 of bottom can guide whirlwind to be rotated down.

Filter 31 bottoms are also provided with outward extending dust-leading board 313, and dust can fall into centrum 2 bottoms along dust-leading board 313.

Center mozzle 32 is arranged in filter 31, and it is shaped as bottom and becomes the cylindrical shape of coniform and sealed bottom. Mozzle 32 sidewalls in center are surrounded with multiple fish scales hole 4. As shown in Figure 4, fish scale hole 4 towards with filter 31 fish scale holes 4 towards identical, for filter bag dirt high-pressure blast for the second time. Mozzle 32 tops in center are communicated with air outlet 13, and the high-pressure blast after filtering is discharged. Mozzle 32 tops in center are provided with the structure with the clamping of filter top seal, with easy disassembly.

Described air outlet 13 is provided with screen pack, with intensive filtration effect.

The utility model is work like this: from air inlet 12 enters cavity 1, under the guiding of deflector 312, rotate to form whirlwind in cavity 1 inner high speed with dirt high pressure gas, the rub rear kinetic energy of flap 41 of filter 31 projections of dust wherein reduces gradually, finally falls under gravity in the disposal box of centrum 2 belows.

High pressure gas after filtering for the first time enters filter 31 inside from fish scale hole 4, is still cyclone type rotation, then after the flap friction around center mozzle 32 projections, falls into dust collecting box. Filter the whirlwind after purifying is being discharged from air outlet 13 by fish scale hole 4.

The utility model has double filtration parts, filter 31He center mozzle adopts fish scale hole 4 to filter band dirt gases at high pressure, gas with dust makes constantly friction reduction kinetic energy of dust and flap 41 in the interior continuous rotation of filter 31, finally falls into centrum 2 and dust collecting box 21. Flap 41 plays the effect that stops and postpone, and gas with dust need to be walked around flap 41, can directly not enter in fish scale hole 4, has obtained than the better filter effect of general cyclone filter. Fish scale hole 4 adopts large aperture, can not cause too high attenuation to blast, has mated well the follow-up high blast filter re-using, and this practicality is simple in structure, with low cost, easy to maintenance.

The utility model is not limited to following embodiment, if various changes of the present utility model or distortion are not departed to spirit and scope of the present utility model, if within these changes and distortion belong to claim of the present utility model and equivalent technologies scope, the utility model is also intended to comprise these changes and distortion.
