Abstract
The utility model relates to a dust separating device of a dust collector. The dust separating device comprises a separation container. An external mesh filter is arranged in an inner cavity of the separation container, and the tail end of the filter extends into a dust collection cavity; a downstream mesh filter is additionally arranged on the inner side of the external mesh filter; a cyclone cone is arranged at the center of the inner cavity of the separation container; and a plurality of internal air outlets are additionally arranged between the downstream mesh filter and the cyclone cone. The dust separating device of the dust collector has the beneficial effects that by adoption of a single-cone and multistage-separation structure and additional arrangement of the plurality of air outlets, air outlet areas are enlarged; and one part of airflow processed at upstream is directly discharged from a separator, and the other part of the air flow is separated further and then is discharged from the separator, so that the filtering efficiency is enhanced, and the pressure loss on the filter is reduced greatly.
Description
Technical field
The utility model relates to the dust catcher technology, relates in particular to a kind of dust catcher dust-separating appliance.
Background technology
The operation principle of dust catcher is to utilize the motor drives blade to rotate at a high speed, in the housing of sealing, produces air negative pressure, draws the dirt bits; The dust catcher of existing a lot of whirlwind modes; Its mode of operation is after sucking the air that is mixed with dust, the air that is mixed with dust to be rotated at a high speed; Centrifugal force through rotary air then; From the air that is mixed with dirt with dust or little dirt with after heavily throw away one by one to light order, trap dust that throws away or little dirt in the dirt bucket.But, in all kinds of dust catchers, especially adopt the multistage cup type dust catcher of dirt that carries out cyclonic separation of single awl; Because separator is only only for an air outlet; This receives the restriction in separator space, and air outlet can not be decontroled excessive, and the flow of separator processing is less like this; If dust concentration is bigger, then has little time to handle, thereby cause the efficient of separator separates not high.Therefore, in conjunction with above aspect, need reasonably improve prior art.
The utility model content
To above defective, the utility model provides a kind of can realize rapidly that dust is separated from the gas, improve filter efficiency, significantly reduce the dust catcher dust-separating appliance of the pressure loss on the filter, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of dust catcher dust-separating appliance; Comprise separation container; Be provided with outer mesh filter in this separation container inner chamber; A downstream mesh filter is set up in said outer mesh filter inboard, is positioned at separation container lumen centers position and is provided with the whirlwind cone, sets up gas channel between this downstream mesh filter and the whirlwind cone.Be provided with the central gas stream passage in the mesh filter of said downstream, and the air-flow of the gas channel between mesh filter and whirlwind cone separates the back through the whirlwind cone and flows out from the central gas circulation road; Said gas channel is cut into several autonomous channels by cutting plate, and it is peripheral and tangent that cutting plate is uniformly distributed in the whirlwind cone; Said outer mesh filter bottom has the shirt rim, and this shirt rim becomes 30 °-60 ° angle with the axis of separation container.
The beneficial effect of the described dust catcher dust-separating appliance of the utility model is: through adopting single awl multi-stage separation structure and setting up a plurality of air outlets; Increased air-out area, through the air-flow after the upstream process, a part is directly discharged from separator; Another part is then through further separating; From separator, discharge, thereby improved filter efficiency, significantly reduced the pressure loss on the filter.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the internal structure sketch map of the said dust catcher dust-separating appliance of the utility model embodiment;
Fig. 2 is the partial top view of the said dust catcher dust-separating appliance of the utility model embodiment.
Among the figure:
1, air outlet; 2, air inlet; 3, separation container; 4, dust-collecting cavity; 5, outer mesh filter; 6, downstream mesh filter; 7, gas channel; 8, central gas stream passage; 9, whirlwind cone; 10, cutting plate.
The specific embodiment
Shown in Fig. 1-2; The described dust catcher dust-separating appliance of the utility model embodiment; Comprise separation container 3, separation container sets out air port 1, air inlet 2 respectively in both sides about in the of 3, is provided with outer mesh filter 5 in these separation container 3 inner chambers and this filter end stretches in the dust-collecting cavity 4; Simultaneously; Be positioned at outer mesh filter 5 inboards and set up a downstream mesh filter 6; Be positioned at separation container 3 lumen centers positions and be provided with whirlwind cone 9, air outlet 7 in setting up between downstream mesh filter 6 wherein and the whirlwind cone 9, whirlwind cone 9 outer ends wherein are provided with central gas stream passage 8.Said gas channel 7 is cut into several autonomous channels by cutting plate 10, and it is peripheral and tangent that cutting plate 10 is uniformly distributed in whirlwind cone 9.
The described dust catcher dust-separating appliance of above the utility model embodiment; During work; Dusty gas flows into from air inlet 2, the air-flow after being handled in succession with downstream mesh filter 6 these two mesh filter by outer mesh filter 5, and a part is discharged through interior air outlet 7 and air outlet 1; A part then after whirlwind cone 9 is handled, is discharged from central gas circulation road 8 and air outlet 1.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
