Particularly, cyclone separator 1 comprises: cyclone cylinder 11, be placed in cyclone cylinder 11 interior centers filter 13, be positioned at the cyclone separator end cap 12 of filter 13 tops, gapped between cyclone separator end cap 12 and the upper edge of cyclone cylinder 11, be connected with blast pipe 17 at the bottom centre position of cyclone cylinder 11, dusty gas accelerates rotation via its inner wind deflector 15 after entering cyclone cylinder 11 by blast pipe 17 again, and wind deflector 15 is between blast pipe 17 and filter 13.
Downside position, the center air inlet structure of cyclone separator 1, reduce power loss, move on getting rid of that grey position is maximized simultaneously, utilize efficient cyclone separator, allow dust-contained airflow on spiral runway, accelerate to rise, 360 comprehensively freely dish out, and are no longer limited to and get rid of grey position, allow separate more thorough, the ribbons such as while hair also throw away like a cork, the suction of complete machine no longer declines because filter cotton stops up very soon, will greatly improve separative efficiency, extends the cleaning time of filter cotton.
Ordinary skill people personnel are understandable that, after cyclone separator end cap 12 and filter 13 can be formed as one or form multiple parts, assemble; Blast pipe 17, wind deflector 15 and cyclone cylinder 11 are assembled after can being formed as one or forming multiple parts; Filter 13, cyclone separator end cap 12 and blast pipe 17 are assembled after can being formed as one or forming multiple parts; Wind deflector 15 and cyclone cylinder 11 are assembled after can being formed as one or forming multiple parts.
Downside position, dust collect plant 100 center air inlet structure, greatly shorten the length of blast pipe 17, reduce power loss, the 360 comprehensive dust of freely dishing out, are no longer limited to and get rid of grey position, make separation more thorough, the ribbons such as while hair also throw away like a cork, the suction of complete machine no longer declines because filter cotton stops up very soon, will greatly improve separative efficiency, extends the cleaning time of filter cotton.
Be all known for those of ordinary skills according to other formations of the dust collect plant of the dust catcher of the utility model embodiment and operation, be not described in detail here.
In the description of this description, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, to the schematic statement of above-mentioned term not must for be identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiment or example.In addition, those skilled in the art can engage the different embodiment that describe in this description or example and combine.
