Description
Technical field
The utility model belongs to technical field of new energies, particularly relates to a kind of axial flow centrifugal blower.
Background technique
Centrifugal blower is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, it is a kind of driven fluid machinery.Centrifugal blower is widely used in factory, mine, tunnel, cooling tower, vehicle, the ventilation of boats and ships and building, dust discharge and cooling; The ventilation of boiler and industrial furnace and air inducing; Cooling in the apparatus of air conditioning and domestic electric appliance and ventilation; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.Centrifugal blower is the principle being converted to potential energy according to kinetic energy, utilizes the impeller of High Rotation Speed to be accelerated by gas, then slows down, changes the flow direction, makes kinetic energy convert potential energy (pressure) to.In one-stage centrifugal blower fan, gas is from axially entering impeller, and gas flow changes over radial direction when impeller, then enters Diffuser.In Diffuser, gas and changing flow direction causes deceleration, and this decelerating effect converts kinetic energy to pressure energy.Pressure increases and mainly occurs in impeller, and next occurs in diffusion process.In Multi-stage centrifugal fan, make air-flow enter next impeller with return channel, produce more high pressure.Such as Chinese patent 201310732335.8 discloses a kind of centrifugal blower, comprise the housing, support, exhaust outlet and the intake grill that are made up of upper shell and lower shell body, it is characterized in that: the joint of upper shell and lower shell body is provided with some fixed triangle iron, housing both sides are provided with the stiffening rib be connected with support, intake grill outer end is provided with fixed plate, and housing is provided with the cell body with fixed plate adaptation; The below of described support is provided with base plate, and described base plate comprises vibration damper and assembly department, and described vibration damper top is provided with bolt, and described assembly department is provided with groove, and described bolt fixes with nut through after groove.The blower interior temperature of this structure is very high, causes power of fan to reduce, thus affects normal use and the working life of blower fan.
Summary of the invention
The utility model provides a kind of axial flow centrifugal blower, to solve the high problem of the inside temperature that proposes in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of axial flow centrifugal blower, it is characterized in that: comprise outer cover, body of heater, described outer cover is positioned at the top of described body of heater, running shaft is provided with in described body of heater, the spacing collar is provided with in described outer cover, described running shaft is positioned at the described spacing collar, impeller is covered with outside described running shaft top, protective net is provided with above described outer cover, described impeller is between described protective net and outer cover, described running shaft top is taper, the shape of described impeller matches with running shaft, described running shaft top is provided with reinforcement plate, described reinforcement plate is bolted on running shaft, the diameter of described reinforcement plate is greater than described running shaft, described body of heater comprises end cap, connecting plate is provided with below described end cap, dunnage is provided with below described connecting plate, described dunnage inner hollow, both sides are equipped with circular hole, spacing collar is provided with in described body of heater, described running shaft is positioned at described spacing collar, on described running shaft, cover has guide vane, commutator, the first stator is provided with between described guide vane and commutator, second stator, described first stator and the second stator lay respectively at described running shaft both sides, first-class pearl bearing is provided with between described first stator and described spacing collar, second pearl bearing is provided with between described second stator and described spacing collar.
Described first stator and the second stator are symmetrical arranged.
Described first-class pearl bearing and second pearl bearing are symmetrical arranged.
The beneficial effects of the utility model are:
1 the technical program is by being set to inner hollow by dunnage, and inside is provided with circulating water, and can be sucked by the heat in stove in time, then discharge, radiating effect is ideal, and cost is low, easy to operate, and water source can recycle, energy saving.
The setting of 2 guide vanes, mainly plays centrifugal action, can enter in stator by the gas in stove by lower end in stove, and hydrous water circulation cooling forms cool cycles from the inside to the outside.
Acting as of 3 protective nets prevents wheel speed too fast, departs from running shaft, thus there is potential safety hazard.
4 running shaft tops adopt conical design, can increase the area of contact between running shaft and impeller, increase frictional force, save the consumption of the energy.
5 stream pearl bearings the running can accelerating stator is set, thus improve fan operation efficiency.
