Abstract
The invention discloses a double suction sirocco fan with multi-directional wind blowing, which comprises two coaxial vane wheels, namely the first vane wheel and the second vane wheel, a vane wheel isolating plate located between the first vane wheel and the second vane wheel, a motor shaft passing through the center of the vane wheel isolating plate, a first air flow exhaust channel guiding the air flow of the first vane wheel and a second air flow exhaust channel guiding the air flow of the second vane wheel. A first volute casing sleeved outside the first vane wheel and a second volute casing sleeved outside the second vane wheel are formed respectively, and the first volute casing and the second volute casing are movably connected so that a wind outlet of the first air flow exhaust channel and a wind outlet of the second air flow exhaust channel can face different directions. With the same rotating speed, the double suction sirocco fan has far greater wind blowing rate than a common fan. Wind can be blown in different directions through angle adjustment. With the same wind blowing rate, the double suction sirocco fan has far lower rotating speed than the common fan and has lower noise.

Technical problem to be solved by this invention is to provide a kind of adjusting by angle can realize the double suction Xi Luoke centrifugal cutter of the multi-faceted air-out of multi-faceted air-supply.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of double suction Xi Luoke centrifugal cutter of multi-faceted air-out, comprise two coaxial first impeller, second impellers, impeller dividing plate between first impeller and second impeller, pass the motor shaft at impeller dividing plate center, drive the motor that motor shaft rotates, be enclosed within the spiral case of the side directed air flows of impeller outer, first grate flow channel and the second mobile grate flow channel of guiding second impeller air that guide first impeller air to flow, first spiral case that is enclosed within first impeller outside forms with second spiral case that is enclosed within second impeller outside is independent respectively, first spiral case and second spiral case link together versatilely, make the exhaust outlet of first grate flow channel and the exhaust outlet of second grate flow channel can aim at different directions.
The exhaust outlet of described first grate flow channel is formed with two on first spiral case, the exhaust outlet of second grate flow channel forms on second spiral case and also is formed with two.
The exhaust outlet of described two first grate flow channels is becoming on first spiral case on the both direction in opposite directions of 180 degree, and the exhaust outlet of described two second grate flow channels is on the both direction in opposite directions that also becomes 180 degree on second spiral case.
The exhaust outlet of described two first grate flow channels becomes Vertical direction with the exhaust outlet of two second grate flow channels.
On first spiral case and contacted two faces of second spiral case, be formed with a circle annular protrusion on one of them face, be formed with the annular concave groove of a circle on another face, projection can be inserted in the concave groove, make the projection and concave groove is combined closely and under external force projection can rotate at concave groove, first spiral case and second spiral case are linked together versatilely.
The invention has the beneficial effects as follows: under rotating speed, air quantity is far longer than conventional fan.Adjusting by angle can realize multi-faceted air-supply.Under air quantity, rotating speed is well below conventional fan, and noise is low.Two-part air quantity adjustable ratio can satisfy different requirements.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
The working principle of double suction Xi Luoke centrifugal cutter of the present invention is identical with prior art, can be with reference to prior art, so no longer narration, the present invention and the difference of prior art are that the worm frame of double suction Xi Luoke centrifugal cutter is different, are described in detail below:
As Fig. 3, shown in 4, the double suction Xi Luoke centrifugal cutter of multi-faceted air-out of the present invention, comprise two the first coaxial impellers 1 and second impeller 2, impeller dividing plate 3 between first impeller 1 and second impeller 2, pass the motor shaft 4 at impeller dividing plate 3 centers, drive the motor (not shown) that motor shaft rotates, be enclosed within the spiral case of the side directed air flows of impeller outer, guide first grate flow channel of first impeller, 1 air flows and second grate flow channel of guiding second impeller 2 air flows, be enclosed within first spiral case 11 and independent respectively formation of second spiral case 12 that is enclosed within second impeller, 2 outsides in first impeller, 1 outside, first spiral case 11 and second spiral case 12 link together versatilely, make the exhaust outlet 17 of first grate flow channel and the exhaust outlet 18 of second grate flow channel can aim at different directions.The exhaust outlet 17 of first grate flow channel described in the present embodiment is formed with two on first spiral case 11, the exhaust outlet 18 of second grate flow channel forms on second spiral case 12 and also is formed with two.The exhaust outlet 17 of described two first grate flow channels is becoming on first spiral case 11 on the both direction in opposite directions of 180 degree, and the exhaust outlet 18 of described two second grate flow channels is becoming on the both direction in opposite directions of 180 degree on second spiral case 12.And 18 one-tenth Vertical direction of exhaust outlet of the exhaust outlet 17 of two first grate flow channels and two second grate flow channels.
