Description of the drawings
Fig. 1 is damping blower fan structure schematic diagram.
Fig. 2 is damping blower volute structure schematic diagram.
In figure label for：Spiral case 1, air inlet 2, air outlet 3, motor 4, impeller 5, rubber pad 6, web plate 7, explosion-proof layer 8.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, damping wind turbine, including spiral case 1, spiral case 1 is equipped with air inlet 2 and air outlet 3, is set to
Impeller 5 in spiral case 1, the shaft of impeller 5 are connect with the motor 4 outside spiral case 1, further include the side for placing motor 4 and spiral case 1
Shape pedestal, four angles of square base are equipped with rubber pad 6, and the pedestal is divided into the fixed frame of upper end and the pedestal of lower end, rubber
Rubber cushion 6 includes installation screw, rubber, and installation screw upper end is threadedly coupled with fixed frame, and lower end is fixed with rubber, and rubber has outer
Set, housing are screwed in pedestal, constitute pedestal damping, and the air inlet 2 of the spiral case is provided with blocking particle
The web plate 7 of impurity is coated on the web plate 7 and is coated with are-tight paint, and the spiral case 1 is internally provided with explosion-proof layer 8, is set on impeller 5
There is wearing layer.
As shown in Fig. 2, web plate 7 is general metal otter board, it can be aluminium or iron, are-tight paint, web plate 7 are coated on web plate 7
It can effectively stop the particle foreign matter more than 7 aperture of web plate, prevent particle lump from entering wind turbine, take turns and occur with wind turbine internal lobe 5
Friction, sparking, when there is the particle less than web plate aperture to enter wind turbine, wind turbine inner casing also has one layer of explosion-proof layer, the explosion-proof layer
For general zinc-plated explosion-proof Steel material, there is anti-explosion fire, explosion-proof layer is fixed on explosion-proof screw in spiral case 1, with snail
There are cavitys between shell 1.
As shown in Figure 1, the impeller 5 of this damping explosion-proof fan is equipped with wearing layer, the wearing layer can be that silicon carbide gathers
Ether sulfone wear-resistant paint layer or polymer ceramic.
Little particle hard object in part possibly can not be stopped by web plate 7 as shown in Figure 2, can still enter blower interior, with
Impeller 5 shown in FIG. 1 rubs, and impeller 5 is caused to be lost, and metal composite technology is used to impeller 5, in groundwork surface shape
Into one layer of wearing layer, polymer ceramic impeller can effectively place scraping, extend fan life, and fan life is made to improve three times
More than, due to 5 working surface composite ceramic layer hardness HRA >=86 of draught fan impeller, the serious position of concentrated wear uses double sintering
Silicon nitride toughening ceramic or Zirconia reinforced alumina ceramic, highest can reach more than HRA94, resistance to particle erosive wear
It can be at least the conventional treatments modes such as common tungsten carbide built-up welding, spraying surfacing and the welding of alloyed powder bulk and improve 5 times or more, thickness
It spends and is actually used 5 years for 1.5mm potsherds, average abrasion is less than 0.2mm, while polymer ceramic has good temperature tolerance
Can, fire prevention, explosion-proof effect are played to a certain extent.
As shown in Fig. 2, web plate 7 is connect with 1 air inlet 2 of spiral case using dismountable mode, such as it is clamped or is connected by screw
It connects, cleaning easy to disassemble.
