Abstract
The utility model discloses a high-temperature resistance mixed-flow fan, which comprises an outer tube, an inner tube, an impeller and a motor, wherein the motor is arranged inside the inner tube, a wheel hub is sheathed and arranged on an output shaft of the motor, the impeller is fixed on the outer wall of the wheel hub, the inner tube is sheathed and arranged at one end of the motor, corresponding to the output shaft and is matched with the wheel hub for surrounding the motor, a gap is formed between the inner tube and the wheel hub, and an air guide pipe used for conveying cold air is arranged between the inner tube and the outer tube. The fan of the utility model has the advantages that because of the burbling effect of cooling blades, the cold air can surround the surfaces of the whole motor, the heat radiation effect of the motor can be improved, the service life of the motor can be prolonged, the smooth and reliable operation of the fan can be ensured, the air flow is more stable and more uniform through the adoption of a flow collector, the eddy flow can be reduced, the noise generated by high-speed movement of the air flow can be greatly reduced, and the energy loss can be reduced. Guide blades are arranged between the inner tube and the outer tube, so an air flow smoothly passes through the air tube through being guided by the guide blades, and the problem that huge noise generated by the severe collection of the air flow influences the equipment stability and pollutes environment can be avoided.
Description
Technical field
The utility model relates to the gas transportation facilities technical field, relates in particular to a kind of high temperature resistant flow-mixing blower fan.
Background technique
Blower fan comprises the urceolus of impeller, drive motor and parcel impeller and drive motor; According to unusual ventilator, blower, compressor, Roots blower, centrifugal fan, rotary type blower fan and the water ring type blower fan of being divided into of function.
Blower fan is that a kind of mechanical energy that relies on input improves supply gas the side by side mechanical device of body of gas pressure.Blower fan be widely used in the oven dry of the ventilation of ventilation, dust discharge and cooling, boiler and industrial furnace of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building and the cooling in air inducing, the apparatus of air conditioning and the domestic electric appliance and ventilation, cereal and select and recommend, the inflation of wind-tunnel wind regime and Hovercraft and propelling etc.
Present most of blower fan generally is applicable to the conveying of cold wind, and when blower fan was used for heat air delivery, the blower fan bulk temperature can increase, and can cause the damage of motor bearings when temperature is too high, has increased the blower fan acquisition cost.
Summary of the invention
The utility model provide a kind of simple in structure, can be used for the high temperature resistant flow-mixing blower fan that hot blast is carried.
A kind of high temperature resistant flow-mixing blower fan comprises the motor in urceolus, inner core, impeller and the inner core, is arranged with wheel hub on the output shaft of described motor, and impeller is fixed on the outer wall of wheel hub; Inner core is sheathed on an end of the relative output shaft of motor and cooperates the motor encirclement with wheel hub, leaves the gap between inner core and the wheel hub, is provided with the guide duct that is used for transporting cold wind between urceolus and the inner core.
For the cold wind that enters inner core plays sufficient cooling action, be provided with cooled blade at the inwall of wheel hub; When cold wind is passed into cavity in inner core and the wheel hub by guide duct, high speed rotating along with impeller, cooled blade rotates thereupon, air-flow flows in the disturbance wheel hub, make the inner core inwall form the air motion of stable circulation, the gas flow rate on increase motor surface improves radiation effect of motor, prolong the working life of motor, guarantee the steadily reliable of blower fan running.
The intake grill end of urceolus is provided with slip ring; Slip ring is to design according to Venturi principle, external frame is taper, and circular arc inlet with level and smooth deflation, can the more quick and convenient output of steering flow, improve the efficient of output gas, make air-flow more steadily evenly, reduce turbulent flow, reduce the noise that the air-flow high-speed motion produces greatly, reduce the loss of energy.
Interfix by stator between inner core and the urceolus; In addition, stator can be designed to circular arc, and air-flow smoothly passes air duct under the guiding of stator, avoids the air-flow sharp impacts to produce huge noise, influences stabilization of equipment performance and befouling environment.
During blower fan work, impeller rotates under the drive of motor, attract air-flow to enter from slip ring, flow through air duct fast, form negative pressure, guide extraneous cold wind to be passed in the inner core by guide duct at wheel hub and inner core surface, under the drive of cooled blade, cold wind is covered with whole motor surface, and then discharges by the slit that wheel hub and inner core form, and forms stable circulation cooling blast.
The beneficial effects of the utility model are embodied in:
(1) utilizes the flow-disturbing effect of cooled blade, make cold wind can surround whole motor surface, improved radiation effect of motor, prolong the life-span of motor, guarantee that the blower fan running is steadily reliable;
(2) employing of slip ring makes air-flow more steadily evenly, reduces turbulent flow, reduces the noise that the air-flow high-speed motion produces greatly, reduces the loss of energy;
(3) between inner core and urceolus, stator is installed, is made air-flow under the guiding of stator, smoothly pass air duct, avoid the air-flow sharp impacts to produce huge noise, influence stabilization of equipment performance and befouling environment.
