Description

Motor air intake dust filtration device
Technical field
The utility model relates to the dust filtration device being assemblied in self-ventilated machine air inlet, is specially a kind of motor air intake dust filtration device.
Background technology
At present, self-ventilated machine is simple with its structure, easy care, the favor thus obtain that the little and little advantage that takes up space of noise is subject to motor user is generally applied, and the molecule in the cooling-air entered, damage can be caused to winding insulation in motor, affect electrical machinery life, therefore, the dedusting structure of self-ventilated machine and device, and its dust removing effects causes the most attention of people.Mostly rely on air inlet the to arrange instructions for use that dust excluding hood carrys out satisfied clean cooling air of existing self-ventilated machine.Existing dust excluding hood structure arranges several metafiltration net in air inlet, and the filter dirt material of filter screen central filler densification reaches certain filter dirt effect.But its complex structure, windage is comparatively large, and dust enters rear easy obstruction filter screen, and not easy-clear, affects the inlet of cooling air, and then makes cooling effect reduce, and this structural maintenance difficulty cost is high.
Summary of the invention
The utility model greatly, easily causes and blocks inconvenience in order to solve existing self-ventilated machine dust excluding hood structure windage and remove, not easy care and the high technical problem of maintenance cost, provides a kind of motor air intake dust filtration device.
The utility model realizes by the following technical solutions: a kind of motor air intake dust filtration device, comprises a shell in convex structure; The side of shell has air inlet, and the bottom of shell has air outlet, and air inlet is provided with protective cover; The position that enclosure is adjacent with air outlet is provided with the dust collecting trough of a upper opening, isolated by a dividing plate be fixed between outer casing inner wall between dust collecting trough and air outlet; A lower wind deflector is provided with above dividing plate, the air inlet of shell extends internally and is provided with one is the convex structure and the upper wind deflector be positioned at above air outlet that match with shell circular arc, form air intake passage between upper wind deflector and outer casing inner wall, the lower end edge of upper wind deflector is positioned at the top of lower wind deflector and has gap therebetween; Dust collecting trough is connected with the dust removal port towards motor internal.
The utility model is arranged on the air inlet of motor, and during installation, air outlet is to the air inlet of alignment motor.Wind deflector forms by upper and lower two pieces, and the cooling-air being filtered dirt by protective cover first, under the effect of centrifugal fan, is imported by the cavity (air intake passage) of upper wind deflector and shell composition; Lower wind deflector and shell composition cavity at cooling air through out-of-date; wherein particle dust is under centrifugal force and Action of Gravity Field; inwall along shell and lower wind deflector is slipped in dust collecting trough; the gap that the cooling air of filtering is formed from upper wind deflector, lower wind deflector and shell enters motor, plays the effect of filtering and cooling.
Motor air intake dust filtration device structure described in the utility model is simple, and windage is little, easy care, and convenient maintenance, has greatly saved clean and maintenance cost, can be widely used in the filter dirt of self-ventilated machine air inlet.

Embodiment
A kind of motor air intake dust filtration device, comprises a shell 1 in convex structure; The side of shell 1 has air inlet 7, and the bottom of shell 1 has air outlet 8, and air inlet 7 is provided with protective cover 2; The inner position adjacent with air outlet 8 of shell 1 is provided with the dust collecting trough 5 of a upper opening, isolated by a dividing plate be fixed between shell 1 inwall between dust collecting trough 5 and air outlet 8; A lower wind deflector 4 is provided with above dividing plate, air inlet 7 place of shell extends internally and is provided with one is the convex structure and the upper wind deflector 3 be positioned at above air outlet 8 that match with shell circular arc, form air intake passage between upper wind deflector 3 and shell 1 inwall, the lower end edge of upper wind deflector 3 is positioned at the top of lower wind deflector 4 and has gap therebetween; Dust collecting trough 5 is provided with the dust removal port 6 towards motor internal.
Air inlet 7 axis and the air outlet 8 axis angulation a of shell 1 are 45 ~ 70 degree.
As described in Figure 1, the air inlet of dust filtration device described in the utility model is positioned at side, and air outlet is then positioned at below.The air intake gap 10 that gap as seen from Figure 2 between the two axis at an angle and up and down between wind deflector and outer casing inner wall is formed.Air outlet is other is provided with dust collecting trough 5, for collecting the larger particle entered in dust filtration device; Air intake passage is connected with dust collecting trough 5 upper opening.Through protective cover 2 wind outside through one in the air intake passage of arc-shaped and air intake gap 10 enter motor internal.Upper wind deflector 3 in convex structure is positioned at above air outlet 8, can prevent larger particle from entering stator winding and rotor.
Shell 1 is shaped by light sheet bending or welding, and its inwall adopts arc transition, to reduce windage.
Protective cover 2 meets certain degree of protection requirement, carries out ground floor filtering to cooling air, and larger particle sand and dust are blocked in outside motor.
Wind deflector is upper wind deflector 3 and lower wind deflector 4 two pieces formation.
Under in shell 1, the bottom of wind deflector 4 is provided with dust collecting trough 5.
Dust removal port 6 is connected by air duct on support 11 with dust collecting trough 5.
Dust, by dust collecting trough 5, avoids stator winding and rotor through upper air duct 11(specific on stator), from dust removal port 6(dust removal port towards motor internal) enter motor internal, then by fan, discharge outside motor together with cooling air.Dust is to the pollution of the pollution of motor mainly stator winding and rotor; and adopt structural design described in the application; because dust can avoid stator winding and rotor; dust and cold wind is equivalent to separate; dust walks around stator winding and rotor; cold wind through stator winding and rotor, and then is discharged in the lump, so play the effect of dedusting protection.
