Description
Technical field
The utility model belongs to technical field of motor manufacture, particularly a kind of motor sliding ring chamber carbon powder filter.
Background technology
In motor operation course, electric current is outwards derived by slip ring and carbon brush, motor High Rotation Speed makes slip ring and carbon brush rub and produces a large amount of carbon dust, carbon dust accumulates and easily causes electric motor short circuit at slip ring room, in order to the environment of clean slip ring room, usual way introduces clean air to slip ring room, but carbon dust directly enters air serious environment pollution again; At present, charcoal powder filter is blown into formula charcoal powder filter, easily brought in slip ring room by the dust in outside air, and the filter being blown into formula easily causes carbon dust pile up at motor internal and cause short circuit.
Utility model content
The purpose of this utility model is to propose a kind of motor sliding ring chamber carbon powder filter, and the dust in outside air, than the traditional formula that is blown into charcoal powder filter more environmental protection, can not be brought in slip ring room by this device; And this apparatus structure is simple, be easy to processing, with low cost, can produce in enormous quantities.
For reaching above-mentioned technical purpose, the utility model adopts following technical scheme to be achieved.
A kind of motor sliding ring chamber carbon powder filter, it is characterized in that, comprise the mounting panel being arranged on the outlet of slip ring room rear portion, described mounting panel is provided with blower fan, the air inlet of described blower fan and slip ring room rear portion outlet, the periphery of described mounting panel is provided with ventilating duct, the inner circumferential of described ventilating duct is provided with tubular screen pack, air channel is formed between described ventilating duct and screen pack, the outer end of described screen pack is provided with back shroud, described back shroud be provided with the ventilating opening be communicated with described air channel between ventilating duct.
Feature and further improvement of the technical program are:
Described back shroud is fixed on mounting panel by double threaded screw.
Described back shroud is set to arc-shaped.
Motor sliding ring chamber carbon powder filter of the present utility model, by the carbon dust sucking-off that slip ring in slip ring room and carbon brush grind by blower fan, after carbon dust being filtered by screen pack again, clean air is discharged by air channel and ventilating opening, than the traditional formula that is blown into charcoal powder filter more environmental protection, dust in outside air can not be brought in slip ring room, also can not cause short circuit due to the accumulation of carbon dust; This carbon powder filter is connected by double threaded screw, dismantles more convenient; And this apparatus structure is simple, be easy to processing, with low cost, can produce in enormous quantities.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the half section structural representation of a kind of motor sliding ring chamber carbon powder filter of the present utility model;
In figure: 1, slip ring room; 2, mounting panel; 3, blower fan; 4, ventilating duct; 5, screen pack; 6, back shroud; 7, double threaded screw; 8, air channel; 9, ventilating opening.
Embodiment
With reference to Fig. 1, it is the structural representation of a kind of motor sliding ring chamber carbon powder filter of the present utility model; This carbon powder filter comprises the mounting panel 2 being arranged on the outlet of slip ring room 1 rear portion, mounting panel 2 is provided with blower fan 3, the air inlet of blower fan 3 and slip ring room 1 rear portion outlet, the periphery of mounting panel 2 is provided with ventilating duct 4, the inner circumferential of ventilating duct 4 is provided with tubular screen pack 5, form air channel 8 between ventilating duct 4 and screen pack 5, the outer end of screen pack 5 is provided with back shroud 6, is provided with the ventilating opening 9 be communicated with air channel 8 between back shroud 6 with ventilating duct 4.
Wherein, back shroud 6 is fixed on mounting panel 2 by double threaded screw 7, dismantles more convenient.
Wherein, back shroud 6 is set to arc-shaped, facilitates the derivation of air, forms convection current wind.
Motor sliding ring chamber carbon powder filter of the present utility model, by the carbon dust sucking-off that slip ring and carbon brush in slip ring room 1 grind by blower fan 3, after carbon dust being filtered by screen pack 5 again, clean air is discharged by air channel 8 and ventilating opening 9, than the traditional formula that is blown into charcoal powder filter more environmental protection, dust in outside air can not be brought in slip ring room, also can not cause short circuit due to the accumulation of carbon dust; This carbon powder filter is connected by double threaded screw 7, dismantles more convenient; And this apparatus structure is simple, be easy to processing, with low cost, can produce in enormous quantities.
Although be below described embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art is under the enlightenment of specification, and when not departing from the scope that the utility model claim is protected, can also make a variety of forms, these all belong to the row of the utility model protection.
