Description

The diffusion type dust arrester of dust catcher
Technical field
The utility model relates to a kind of diffusion type dust arrester of dust catcher.
Background technology
Filter all is installed in the dust catcher in the market, purpose is that the dirty air that will suck filters, therefore dust granule is stayed in the dust collect plant,, this type of dust catcher is after using a period of time, the user should clear up filter or change, otherwise, after the filter opening of filter is stopped up by thin dust, can increase the resistance of vacuum motor, severe patient even can burn out motor has not only brought trouble to the user, and can influence the performance and the life-span of dust catcher.
In recent years, manufacturer substitutes filter according to the principle of cyclonic separation with cyclone dust collector, has obtained dust removing effects preferably, the group and be widely applied on the dust catcher.This cyclone dust collector is provided with a conical shell that the upper end is big, the lower end is little in the dirt cup, the upper end of conical shell vertically is provided with a discharge pipe, the lower ending opening of conical shell is so that dust falls into dirt cup bottom, blast pipe also tangentially enters in the conical shell upper portion side wall, make the air-flow that has dust in conical shell, produce whirlwind, dust granule drops to the dust-collecting box bottom at action of centrifugal force lower edge conical shell sidewall, and the air-flow after the dedusting is upwards discharged through discharge pipe.
But above-mentioned dust arrester also exists the bigger shortcoming of volume, and particularly when wind flow required to use on the bigger large-scale dust catcher, the cyclone dust collector volume was just bigger, has not only increased cost, and the user uses also cumbersome.
And big, the little back taper shape in lower end on the rotary barrel of above-mentioned dust arrester is are quickened rotation by air-flow and are come dust-separating, so the pressure loss of air-flow is bigger, thereby have influenced the pick-up performance of dust catcher.
In addition, the air-flow of acceleration will sink to the fine dust of dirt cup bottom easily and kick up once more, and discharge from discharge pipe with air-flow, make air produce secondary pollution.So it is this device is suitable for the separate coarse particulate dust, then relatively poor relatively to the separating effect of fine particle dust.
Summary of the invention
