Abstract
The utility model discloses a screw type dust removal mechanism of a dust collector. The screw type dust removal mechanism of the dust collector comprises a guide blade, a separation outer tube, a separation inner tube and an air-out pipe. The guide blade is fixedly connected with the separation outer tube in a clamping mode. The upper end of the separation inner tube is fixedly connected with the guide blade in a clamping mode and is placed inside the separation outer tube. The air-out pipe is arranged at the lower end of the separation inner tube. A plurality of guide pieces are placed on an inner ring of the guide blade, and an air inlet is formed at one end of the guide blade. The screw type dust removal mechanism of the dust collector is simple in structure. According to a basic principle of aerodynamics, suspended dust particles in the air are enabled to do one-way and deflexion movement and are separated from air flow molecule by applying a flow field with low flow velocity and low turbulence and by utilizing the plurality of italic-shaped guide pieces arranged on the inner ring of the guide blade, so that the purpose of separating the dust is achieved. The screw type dust removal mechanism of the dust collector has the advantages of being small in wind resistance and air quality loss, high in whole machine efficiency and good in separation effect, and secondary pollution of the air cannot be caused.
Description
Technical field
The utility model relates to the dust catcher technical field, relates in particular to the spiral dedusting mechanism on a kind of dust catcher.
Background technology
Traditional dust catcher free-bag structural design is to rely on single-stage or multistage cyclone design, the little air molecule of the large granulated garbage of density and density separated enter dust to receive disposal box, and the simultaneously separated discharge of air, thus reach the effect of dust suction.The structure of this design is to adopt when usually filtering in the second level by a plurality of to revolve the spiral cone that cone forms and make mixing air carry out the high speed whirlwind separation, with the rubbish Re-isolation.The drawback of this structure is air-flow velocity, and thereby very high windage is larger, and the air quantity loss ratio of product is larger, and the whole efficiency of dust catcher is lower.The another one drawback is exactly that spiral cone is more intensive owing to the space, and the separating effect of rubbish is not fine, often causes tiny dust with Bas Discharged, causes air secondary to pollute.
The utility model content
The technical problem that (one) will solve
Problem to be solved in the utility model provides the spiral dedusting mechanism on a kind of dust catcher, and large to overcome in the prior art windage, the air quantity loss is large, and efficient is low, the defective of inferior separating effect.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides the spiral dedusting mechanism on a kind of dust catcher, comprises guide vane, separates outer tube, separates inner tube, escape pipe, and described guide vane connects and fixes with the described outer tube that separates; Described separation inner tube upper end connects and fixes with described guide vane, and is arranged in the described separation outer tube; Described escape pipe is positioned at described separation inner tube lower end; Be provided with some prerotation vanes on the described guide vane inner ring, air inlet is positioned at guide vane one end.
Further, described prerotation vane becomes the italic shape.
Further, described guide vane, separation outer tube, separation inner tube and the coaxial installation of escape pipe.
Further, the external diameter of described separation inner tube is less than the internal diameter that separates outer tube, and the external diameter of described escape pipe is less than the internal diameter that separates outer tube.
(3) beneficial effect
Spiral dedusting mechanism on a kind of dust catcher of the present utility model, simple in structure, according to the aerodynamics basic principle, use low flow velocity, the flow field of low turbulent flow, utilize the some italic shape prerotation vanes that arrange on the guide vane inner ring, so that thereby airborne airborne dust particle can be done the unilateral deflection motion and make it to separate the purpose that reaches dust-separating with the air stream molecule, its advantage is that windage is smaller, the air quantity loss is little, overall efficiency is high, and good separating effect can not cause air secondary to pollute.
