Abstract
The utility model discloses a dust separating mechanism of a dust collector, which comprises a cylinder body with a cyclone chamber, a cyclone inlet bored on the cylinder body and communicated with the cyclone chamber, and an air outlet pipe communicated with a negative-pressure source, wherein the cylinder body is provided with a tubular grille and a filter. The outer side of the filter is communicated with the inner side of the grille via an airflow channel; the inner side of the filter is communicated with the air outlet pipe. Dust enters and stays in the cylinder body from the cyclone inlet, and air with dust particles enters the airflow channel; dust particles are left out of the filter after filtering, and clean air enters the air outlet pipe.
Description
Technical field
The utility model relates to a kind of dust separation apparatus of dust catcher.
Background technology
In the prior art, the dust separation of dust catcher is realized by filter usually, in the cylindrical shell that filters dust, filter bag or filtering bodies are set, filtering bodies and dust suction inlet are adjoining, be filtered the body retaining after making dust in entering cylindrical shell in its outside, but owing to still have tiny grit to pass through in the mesh of filtering bodies, and tiny grit enters on the filter membrane of the porch that can stick to negative pressure chamber behind the air intake passage, operate as normal to motor has caused influence, and need the frequent filtering bodies of removing when using, use cumbersome.
Summary of the invention
The utility model purpose provides a kind of dust separation apparatus of dust catcher, and it can the bigger dust of first separating particles, makes that the life cycle of filter is elongated.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dust separation apparatus of dust catcher comprises cylindrical shell with cyclonic chamber, opens the whirlwind that is connected with the cyclonic chamber inlet on described cylindrical shell, the discharge pipe that is connected with negative pressure source.Be provided with the grid that is tubular in the described cylindrical shell, also be provided with filter in the described cylindrical shell, be connected by gas channel between the outside of described filter and the inboard of described grid, the inboard of described filter is connected with described discharge pipe.
Because technique scheme utilization, the utility model compared with prior art has following advantage: one-level dust separation apparatus and one-level filtration are set in cylindrical shell, it is separated and fall that oarse-grained dust enters in the cylindrical shell back by whirlwind inlet, after passing grid, the air that has a tiny grit enters gas channel, after the filter filtration, tiny grit is stayed the filter outside, pure air enters in the discharge pipe, enter negative pressure source at last, the dust separation apparatus of two-stage makes the utility model can prolong the life cycle of filter, uses also more convenient.

The specific embodiment
Referring to accompanying drawing 2-accompanying drawing 3, a kind of dust separation apparatus of dust catcher, comprise cylindrical shell 2, open the whirlwind that is connected with cyclonic chamber 10 inlet 5 on described cylindrical shell 2, the discharge pipe 9 that is connected with negative pressure source with cyclonic chamber 10, described negative pressure source is the blade of driven by motor, be provided with the grid 3 that is tubular in the described cylindrical shell 2, also be provided with filter 7 in the described cylindrical shell 2, be connected by gas channel 6 between the inboard of the outside of described filter 7 and described grid 3, the inboard of described filter 7 is connected with described discharge pipe 9.
Referring to accompanying drawing 1, dust catcher 1 is provided with negative pressure source, described cylindrical shell 2 is arranged on the dust catcher 1, wherein, have air-out passage 8 in the discharge pipe 9 in the cylindrical shell 2, described air-out passage 8 is connected with the negative pressure cavity of negative pressure source, air-flow during work is then entered by whirlwind inlet 5, behind grid 3, enter gas channel 6, enter air-out passage 8 again after filtering through filter 7 then, enter negative pressure cavity at last.To accompanying drawing 5, described grid 3 comprises the some blades of tilt distribution on same periphery referring to accompanying drawing 2, and the incline direction of each blade is consistent with the opening direction of described whirlwind inlet 5.
The air that has dust enters back rotation in cyclonic chamber 10 in simplified 2, stall fell on the inwall of cylindrical shell 2 after the inwall of oarse-grained dust and cylindrical shell 2 collided, fall then, the air that has thin dirt then enters in the gas channel 6 from grid, filtration through filter 7, thin dirt is trapped in the outside of filter 7, and pure air enters and enters negative pressure source in the air-out passage 8 again.
Referring to accompanying drawing 2-accompanying drawing 3, described filter 7 is positioned at the top of grid 3, the cyclonic chamber 10 at the place, the outside of the outside of described filter 7 and described grid 3 by baffle plate 12 separately, and for dwindling the volume of cylindrical shell 2, described discharge pipe 9 is arranged in the inner chamber of grid 3, and described grid 3, discharge pipe 9, filter 7 coaxial inner conductor ground are provided with.Because air behind grid 3 is subjected to the influence of negative pressure source and is upwards sucked in the gas channel 6, and oarse-grained dust is separated and whereabouts and staying in the cyclonic chamber 10 cylindrical shell 2 in.And be to prevent that the bulky grain dust is inhaled in the gas channel 6 in the slit of grid 3; the bottom of described grid 3 is fixed with the dust block board 4 that radially becomes big; the below of described dust block board 4 is provided with the isolation cylindrical shell 11 that is fixedly connected with grid 3; the bulky grain dust in the outside portion that isolates cylindrical shell 11, can have been improved filter efficiency by dust block board 4 retainings.
