Description
Technical field
The utility model relates to blower technical fields, and in particular to a kind of centrifugal blower.
Background technique
Centrifugal blower is to improve gas pressure by the mechanical energy of input and convey the machinery of gas, and centrifugal blower is used extensively
In the ventilation, dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, ship and building；Boiler and industrial furnace it is logical
Wind and air inducing；Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance；It the drying of cereal and selects and recommends；Worked
Cheng Zhong drives compressor impeller by ordinary motor, and air-flow, axially into blade space, is acted on by blower in high-speed rotating impeller
Further aspect is rotated with impeller, is on the other hand improved energy under the action of inertia, impeller is left along radial direction, by generation
Centrifugal force acting.
Traditional centrifugal blower is used in such a way that gear accelerates, it needs gear up transmission mechanism, conventional
Bearing support and oil lubrication system, this conventional centrifugal blower the problem is that: on the one hand, due to using lubricating oil to machinery
Friction pair is lubricated, and the air for causing blower to export is not able to satisfy the special industries such as food, medicine, electronics with oiliness
Cleanliness without any pollution needs；On the other hand, since the power of ordinary motor output needs to pass to by gear up transmission mechanism
Impeller, in power transmission process, the problems such as great energy loss and noise can be generated because of mechanical friction, and speed increasing gear
The setting of case causes a whole set of Fan Equipment volume big, and occupied space is big.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and it is simple, compact to provide a kind of structure, body
Product is small, and easy to use and reliable, at low cost, wind-force is big, the low centrifugal fan of energy loss.
The purpose of this utility model is completed by following technical solution, a kind of centrifugal blower, comprising: base, snail
Shell, motor and by the motor-driven impeller, the upper surface of base is equipped with a horizontal machine, and motor shaft is from the axle center of spiral case
It protrudes into the spiral case placed vertically, and the motor shaft ends in spiral case are equipped with the impeller axle bed with impeller；Described
Circumferential circulation channel is formed in spiral case, the axial another side of the impeller axle bed is provided with horn-like air-vent.
As preferred: the base is desk-top base, the horizontal machine is equipped on upper transverse plane, side is fixed
The spiral case placed vertically is installed and three is integrally formed；The circulation channel outlet setting upward that is formed in the spiral case and
Outlet end is provided with connecting flange；Mechanical dynamic seal device is set at the motor shaft of the horizontal machine and spiral case axle center.
The utility model is the improvement carried out in prior art basis, it has structure simple, compact, small in size, is made
It is at low cost with convenient and reliable, the features such as wind-force is big, and energy loss is low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A direction view of Fig. 1.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: Fig. 1, shown in 2, one kind described in the utility model
Centrifugal blower, comprising: base 1, spiral case 2, motor 3 and by the motor-driven impeller 4, it is sleeping that the upper surface of base 1 is equipped with one
Formula motor 3, motor shaft 5 are protruded into from the axle center of spiral case 2 in the spiral case 2 placed vertically, and 5 end of motor shaft in spiral case 2
Portion is equipped with the impeller axle bed 6 with impeller 4；Circumferential circulation channel 7 is formed in the spiral case 2, the impeller axle bed 6
Axial another side is provided with horn-like air-vent 8；The horizontal machine 5 can use servo motor or variable-frequency motor, with
Just can be in the direct impeller rotation of motor, adjustable revolving speed, and motor direct-connected can be improved output power, improve work
Make efficiency.
As shown in the figure, the base 1 is desk-top base, the horizontal machine 3 is equipped on upper transverse plane, side is solid
There is the spiral case placed vertically 2 in Dingan County and three is integrally formed；The outlet of circulation channel 79 formed in the spiral case 2 is set upward
It sets, and outlet end is provided with connecting flange 10；Setting is mechanical dynamic at the motor shaft 5 of the horizontal machine 3 and 2 axle center of spiral case
Sealing device 11.
