Abstract
A fan impeller is composed of a transmission ring and blades, wherein the transmission ring is in an annular shape, and the blades are evenly distributed on the transmission ring. The blades are uniformly arranged on the same side wall of the annular transmission ring. A transmission groove is formed in the wall surface of the transmission ring. A power shaft drives the transmission ring to rotate through the transmission groove, and then the blades located on the transmission ring are driven to rotate. The fan impeller is suitable for being installed on annular hollow structural bodies.
Description
Technical field
The utility model relates to a kind of blast fan of hollow ring, belongs to the optimisation technique of blast fan.
Background technique
Usually, draught fan impeller mainly is divided into centrifugal, axial flow and turbo type.These draught fan impellers have a common feature: namely the root of blade all is fixed on the pedestal, and pedestal is connected with line shaft, and during work, line shaft drives the pedestal rotation, and pedestal drives blade rotary again.Draught fan impeller technology maturation, use field with above-mentioned feature are extensive.But this traditional design is difficult to application is installed at some specific space fields, for example will impeller be installed in a ring-type hollow article and identical being difficult to of blast of diverse location in the ring-type hollow article realized.
Therefore, need to seek a kind of Novel fan impeller that is adapted at the interior installation and operation of hollow article of ring-type.
Summary of the invention
The purpose of this invention is to provide a kind of Novel fan impeller that is adapted at the interior installation and operation of hollow article of ring-type.
Technological scheme of the present invention is: a kind of blast fan is comprised of transmission ring 1 and blade 2, and transmission ring is annular, and blade is evenly distributed at transmission ring.
Blade is fixed on outer wall or the inwall of transmission ring, and the two ends of blade extend out from the both sides of transmission ring.
The joint of transmission ring and blade is positioned at 1/3 to 2/3 place of blade.
Be provided with the driving groove coaxial with transmission ring at the transmission ring wall.
Described driving groove is V-shaped groove or curve bath or the square groove of depression.
Described driving groove is V-shaped groove or curve bath or the square groove of projection.
Be provided with driving cog with the axis parallel of transmission ring at described driving groove.
Be provided with friction particles on described driving groove surface.
Beneficial effect:
1, the blade unification is placed on the same sidewall of annular transmission ring, wall at transmission ring is provided with driving groove, line shaft drives the transmission ring rotation by driving groove, and then drives the blade rotary that is positioned on the transmission ring, and the blast fan of this structure is fit to be installed on the hollow structure of annular.

Fig. 2 is side-looking structural representation of the present invention;
Fig. 3 is perspective view of the present invention.
Embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of blast fan is comprised of transmission ring 1 and blade 2, and transmission ring is annular, and blade is evenly distributed at transmission ring.Blade is fixed on outer wall or the inwall of transmission ring, and the two ends of blade extend out from the both sides of transmission ring.The joint of transmission ring and blade is positioned at 1/3 to 2/3 place of blade, normally adopts the mode in putting, and namely transmission ring is positioned at the middle part of blade.Blade and transmission ring adopt the mode manufacturing of integrally formed mode or welding to form usually.
Wall at transmission ring is provided with the driving groove coaxial with transmission ring.Driving groove be provided with various ways, a kind of preferred version is the bathtub construction that is made as depression, for example V-shaped groove or curve bath or square groove; A kind of mode is to be arranged to the track structure of projection, for example v-shaped track or arc track or square track.
Blast fan is installed to when using in the ring-type hollow article, at the hollow article inwall the strong point more than three is set, the strong point and driving groove are the negative and positive coupling, the strong point and driving groove close contact, and the strong point plays support and spacing effect to blast fan.The pto＝power take-off of the power plant of fan and driving groove close contact, and drive the driving groove rotation.Usually, be provided with the effectively parts of capable of reducing friction resistance such as bearing, ball at the strong point.
Be provided with driving cog with the axis parallel of transmission ring at described driving groove.
Be provided with friction particles on described driving groove surface.
In the time of on being applied in blast fan without blade fan, the quantity of blade, area, arrangement angle, true dip direction and torsion, to be complementary with the position of output power, rotating speed, moment of torsion, sense of rotation, intake grill and the exhaust outlet of motor, with the stream pressure of satisfying the demand and the needs of flow.
Above-described embodiment only is interpretation purposes of the present invention, and is not to be limitation of the present invention, and those skilled in the art in essential scope of the present invention, make a variety of changes or substitute, and also should belong to protection category of the present invention.
