Abstract
The utility model relates to a high-efficiency energy-saving fan, a casing of which is a worm-shaped casing body; an air inlet is arranged on the inlet side of the casing; a blade wheel is arranged in the casing body; the blade wheel is connected with a transmission group which is assembled on a bracket, and the transmission group is connected with an electric motor through a coupling. A blade of the blade wheel is in a plate type arbitrary curve structure and is welded in the middle of an arc conic wheel cover and a wheel disc in a flat plate shape. The utility model has the advantages of high efficiency, less noise, reasonable shape of a pneumatic force path of the fan, favorable abrasive resistance, etc.
Description
Technical field
The back novel a kind of novel high-efficiency and energy-saving blower fan that relates to of this practicality.
Background technique
Circulating fluidized bed boiler is at home and abroad developed rapidly and is used widely as a kind of New-type boiler efficient, energy-saving and environmental protection, and it is compared the advantage that has and is with conventional boiler: have fuel tolerance wide, help environmental protection, load adjustment ability is good, ignition heat intensity big, the furnace heat transfer ability is strong, the ash comprehensive utilization performance is good.
The induced draught fan that matches with circulating fluidized bed boiler has higher requirement, requires the fan pressure height, has modulability preferably.Common blower fan is the mode that straight line is connected with curve because of the blade structure of impeller, so the efficient of common blower fan does not reach higher requirement.
Summary of the invention
The purpose of this utility model provides the low novel high-efficiency and energy-saving blower fan of efficient height, noise that a kind of impeller blade is board-like arbitrary curve structure.
The novel high-efficiency and energy-saving blower fan is characterized in that: the casing of this device is the volute housing, is provided with intake grill at the casing inlet side, is provided with impeller in housing, and impeller is connected with transmission group, and transmission group is located on the support, and transmission group is connected with motor by coupling.
Described novel high-efficiency and energy-saving blower fan is characterized in that: the blade of impeller is board-like arbitrary curve structure, is welded in the middle of arc taper wheel cap and the plate shaped wheel disc.
The utility model novel high-efficiency and energy-saving blower fan is compared the advantage that is had with the blower fan of existing conventional method design:
1, efficient height, induced draught fan peak efficiency can reach 87%, exceed prior art induced draught fan 4%-7%.
2, blower fan aerodynamic force channel shape is reasonable, because of the blade-shaped line is board-like arbitrary curve, can reduce the impact of air-flow to blade to greatest extent, and the induced draught fan that the wear resistance that makes impeller is used than existing circulating fluidized bed boiler improves 50%.
3, noise is low, and best efficiency point is 10.2dB than A sound level, is lower than the induced draught fan 5-8dB that existing circulating fluidized bed boiler is used.
4, efficiently distinguish widely, flow-pressure diagram is smooth, thereby makes the adjusting function of blower fan good, and boiler is moved all from low-load (20%) to overburdening (110%) can be satisfied.
Description of drawings
Fig. 1, Fig. 2 are the structural representations of novel high-efficiency and energy-saving blower fan.
Fig. 3, Fig. 4 are the structural representations of impeller.
Embodiment
See Fig. 1, Fig. 2, the novel high-efficiency and energy-saving blower fan, the casing 1 of this device is the volute housing of being made by steel plate, is provided with intake grill 2 at the casing inlet side, in housing, be provided with impeller 3, the blade 10 of impeller is a board-like arbitrary curve structure (Fig. 4), and blade is the high-quality steel and makes, and is welded in arc taper wheel cap 8 and plate shaped wheel disc 9 middle (Fig. 3), impeller is through dynamic balance calibration, therefore running steadily has higher intensity and wear resistance, long service life.Impeller is connected with transmission group 4, and transmission group is located on the support 5, and transmission group 4 is connected with motor 7 by coupling 6.
Claims (2)
1, novel high-efficiency and energy-saving blower fan is characterized in that: the casing of this device is the volute housing, is provided with intake grill at the casing inlet side, in housing, be provided with impeller, impeller is connected with transmission group, and transmission group is located on the support, and transmission group is connected with motor by coupling.
2, novel high-efficiency and energy-saving blower fan according to claim 1 is characterized in that: the blade of impeller is board-like arbitrary curve structure, is welded in the middle of arc taper wheel cap and the plate shaped wheel disc.
