With respect to prior art, the negative pressure in the vacuum cavity of the present utility model can be impelled between pole piece entrance slit and the pole piece exit slit and form high velocity air, but this air-flow direct effect is removed dust to the pole piece surface; Simultaneously, the upper hairbrush that is positioned at pole piece exit slit both sides can carry out last thoroughly cleaning to residual dust, guarantees high dust removal efficiency, improves the surface quality of pole piece, has improved cycle performance and the security performance of battery.And vacuum cavity is tubular housing, and its inside does not have the plane that dust can be resident, therefore can prevent resident in vacuum cavity inside of dust; In addition, the high velocity air of pole piece exit slit can blow away the dust that embeds in the hairbrush, realizes the automatically cleaning of hairbrush, avoids causing secondary pollution.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model and beneficial effect thereof are conducted further description.
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
Fig. 3 is stereogram of the present utility model.
The specific embodiment
Below in conjunction with the specific embodiment and Figure of description the utility model and beneficial effect thereof are done further detailed description, but embodiment of the present utility model is not limited to this.
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of polar sheat slicing machine dust scavenge unit that the utility model provides, comprise vacuum cavity 3, offer respectively pole piece exit slit 4 and pole piece entrance slit 8 on the vacuum cavity 3, pole piece exit slit 4 both sides are provided with hairbrush 6, the two ends of vacuum cavity 3 are connected with suction port 1, and vacuum cavity 3 is tubular housing.
Wherein, the cross section of vacuum cavity 3 is circular or oval, and this tube type vacuum cavity 3 inside do not have the plane that dust can be resident, therefore can prevent resident in vacuum cavity 3 inside of dust, avoids causing secondary pollution.The design of the structure of vacuum cavity 3 is got by the hydrodynamic simulation analysis optimization, saves to greatest extent source of the gas when guaranteeing dust removing effects, and guarantees that simultaneously the horizontal wind speed on the pole piece 5 is consistent.When the cross section of vacuum cavity 3 is circle, can satisfy above-mentioned requirements.
Wherein, the negative pressure in the vacuum cavity 3 impels pole piece entrance slit 8 and pole piece exit slit 4 to form high velocity air, but direct effect is removed dust to pole piece 5 surfaces.And the upper hairbrush 6 that pole piece exit slit 4 both sides are arranged can carry out last thorough cleaning to residual dust, gas shock and hairbrush brush dust, and two kinds of dedusting method actings in conjunction can be guaranteed high dust removal efficiency.
Wherein, pole piece entrance slit 8 both sides are provided with lower hairbrush 7.Upper hairbrush 6 and lower hairbrush 7 play sealing function, prevent vacuum cavity 1 excessive decompression.
Two suction ports 1 and vacuum cavity 3 smooth connections at the two ends of vacuum cavity 3, concrete, suction port 1 and the integral body of vacuum cavity 3 for seamlessly transitting are to reduce to greatest extent the obstruction in the dust path.
Pole piece entrance slit 8 and pole piece exit slit 4 are symmetrically distributed on the vacuum cavity 3, are convenient to the air-flow stepless action in the pole piece 5 between pole piece entrance slit 8 and pole piece exit slit 4.
Two suction ports 1 at the two ends of vacuum cavity 3 are symmetrically distributed in the two ends of vacuum cavity 3, are convenient to the sucking-off of the dust granules in the vacuum cavity 3.
During actual the use, pole piece 5 from bottom to top enters from pole piece entrance slit 8, passes the lower hairbrush 7 of two rows, enters vacuum cavity 3.For avoiding lower hairbrush 7 that dust is brushed out vacuum cavity 3, lower hairbrush 7 should have certain aperture.
The pole piece 5 of operation is subject to the impact from the high velocity air of pole piece entrance slit 8 and pole piece exit slit 4 in vacuum cavity 3, finishes first dedusting action (air flow impact type dedusting).The lower hairbrush 7 that is arranged at pole piece entrance slit 8 both sides can prevent vacuum cavity 3 excessive decompressions with the upper hairbrush 6 that is arranged at pole piece exit slit 4 both sides, can guarantee the wind speed of impact airflow simultaneously, guarantees the dynamics of air flow impact type dedusting.
Dust by under the lector removing via vacuum cavity 3, is siphoned away by the suction port 1 that is positioned at vacuum cavity 3 two ends, finishes the dedusting action.
The dust of not removed by air flow impact type dedusting action then is with supreme hairbrush 6 places by pole piece 5, and for guaranteeing brush dust dynamics and enough large gas shock dynamics, upper hairbrush 6 needs to arrange less aperture.Pole piece 5 passes the upper hairbrush 6 of two rows' " curtain-type " simultaneously, and residual dust is lower by upper hairbrush 6 brushes, and the dust under the brush is siphoned away by the suction port 1 that is positioned at vacuum cavity 3 two ends via vacuum cavity 3, finishes second dedusting action (dedusting of hairbrush brush dust).
Dust removal efficiency has been guaranteed in two kinds of dedusting actions (air flow impact type dedusting and the dedusting of hairbrush brush dust), the dust that embeds simultaneously in upper hairbrush 6 and the lower hairbrush 7 impacts through the high velocity air that pole piece entrance slit 8 and pole piece exit slit 4 enter, be blown into vacuum cavity 3, thereby realize the cleaning of upper hairbrush 6 and lower hairbrush 7.
And tube type vacuum cavity 3, and guaranteed that with the smooth connection of suction port 1 vacuum cavity 3 is interior without the dead angle, dust is difficult for resident.
The according to the above description announcement of book and instruction, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the utility model just for convenience of description.
