Abstract
The utility model discloses a dust collector dust cup with an oblique helical surface. The dust collector dust cup comprises a cyclone, an air outlet tube and an oblique helical surface, wherein the cyclone is used for generating cyclone separation; the air inlet tube is arranged above the cyclone; and the oblique helical surface is integrally molded on the outer side of the air outlet tube. Through the oblique helical structure, cyclone is enhanced, dust is prevented from rising, and the separation efficiency is increased simultaneously.
Description
Technical field
The utility model relates to a kind of dust cup of dust collector with oblique helicoid.
Background technology
The air-out cover plate that the dust cup of dust collector of multi-stage separation generally includes the one-level cyclone, is positioned at one-level cyclone downstream and has the secondary cyclone of several cyclone unit and is positioned at secondary cyclone top, the air-out cover plate then comprises several discharge pipes 1 that extend into corresponding cyclone unit and the helical structure 2 that is arranged on discharge pipe 1 outside, to strengthen the whirlwind in the secondary cyclone unit, but this helical structure is snail, and the efficiency of dust collection of cyclone unit remains further to be improved.
Summary of the invention
The utility model purpose is: a kind of dust cup of dust collector that improves separative efficiency and have oblique helicoid is provided.
The technical solution of the utility model is: a kind of dust cup of dust collector with oblique helicoid, it comprises: for generation of the cyclone of cyclonic separation, be arranged on the discharge pipe of cyclone top and the oblique helicoid that is shaped in the discharge pipe outside.
On the basis of technique scheme, further comprise following attached technical scheme:
Described cyclone is the one-level cyclone, and this oblique helicoid is from the upper end of discharge pipe toward the lower end rotation, and ecto-entad tilts and intersects an angle a with the center line of discharge pipe simultaneously.
Described angle a spends greater than 15, and less than 60 degree.
Described cyclone is the secondary cyclone, and this secondary cyclone comprises several cyclone unit, and the number of discharge pipe is identical with the number of cyclone unit, and mutually corresponding setting.
It further comprises the air-out cover plate that is positioned at secondary cyclone top and fastens and be used for the dirt cylinder of one-level whirlwind with the air-out cover plate that wherein said discharge pipe and air-out cover plate are wholely set.
The utility model advantage is:
The utility model is strengthened whirlwind by the oblique helicoid structure, prevents that dust from raising up, and improves simultaneously separative efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the generalized section of air-out cover plate in the prior art;
Fig. 2 is the generalized section of air-out cover plate in the utility model;
Fig. 3 is generalized section of the present utility model;
Wherein: 1,12, discharge pipe; 2, helical structure; 10, air-out cover plate; 14, oblique helicoid; 20, secondary cyclone; 22, dust-collecting cylinder; 30, dirt cylinder; 32, guard.
The specific embodiment
Embodiment: shown in Fig. 2-3, the utility model provides a kind of specific embodiment with dust cup of dust collector of oblique helicoid, the dirt cylinder 30 that it comprises air-out cover plate 10, the secondary cyclone 20 with several cyclone unit with several discharge pipes 12 and is positioned at air-out cover plate 10 belows and is used for the one-level whirlwind.Wherein the bottom of secondary cyclone 20 links to each other with dust-collecting cylinder 22, and dust-collecting cylinder 22 is used for collecting the isolated dust of cyclone unit; Dirt cylinder 30 comprises the guard 32 that is set in dust-collecting cylinder 22 outsides.
Air-out cover plate 10 also comprises the oblique helicoid 14 that is integrally formed in corresponding discharge pipe 12 outsides, and discharge pipe 12 is inserted in the cyclone unit and is used for discharge through the air-flow behind the second-order separation.Wherein oblique helicoid carries out spiral rotating from the upper end of discharge pipe 12 toward the lower end, tilts and intersects an angle a with the center line of discharge pipe 12 by the lateral is inboard simultaneously, and this angle a is preferably greater than 15 degree and less than 60 degree, more preferably 45 degree.
Be understandable that discharge pipe 12 of the present utility model not only can be used in the cyclone unit of secondary cyclone, also can be used in one-level or the three grades of cyclones.
The utility model is strengthened whirlwind by the oblique helicoid structure, prevents that dust from raising up, and improves simultaneously separative efficiency.
Certainly above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.The all Spirit Essence of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
