Description
Technical field
The utility model relates to cooling tower apparatus field, is specifically related to a kind of fan wheel hub for cooling tower.
Background technique
Cooling tower, by circulating with spray pattern, sprays on the filler of glass fibre.Filler provides larger surface of contact, by the contact with air, reaches heat transfer effect.Have blower fan to drive airflow circulating in tower again, by with heat exchange after hot air flow take out of, thus reach cooling.
The fan blade of blower fan comprises blade and petiole, and petiole is the link of blade and wheel hub, and blade, petiole, wheel hub composition impeller, impeller is one of topmost operation element of blower fan.At present, along with updating of aeration technology, for improving fan operation efficiency, reducing noise, the connection of ventilating machinary enterprise to wheel hub and petiole has carried out some research.The wheel hub of conventional fan impeller and the fixed structure of petiole adopt simple bolt to fix, still the profile of blower fan is not unsightly like this, and the bolt fastening structure exposed adds resistance when blower fan rotates, and affects fan operation efficiency, also makes fan noise larger.
Application number is the Chinese patent " a kind of wheel hub of draught fan impeller and the fixed structure of petiole " of 201020161216.3, disclose a kind of wheel hub of draught fan impeller and the fixed structure of petiole, described wheel hub comprises the upper wheel hub plate and lower whorl hub that are mutually connected, described wheel hub is provided with at least three petiole mounting holes, described petiole mounting hole comprises installs hole body and mounting hole end, described petiole mounting hole extends from the side face of wheel hub to hub axis direction, described petiole comprises wheel hub linkage section, described wheel hub linkage section comprises coupling shaft and coupling shaft end, the wheel hub linkage section of described petiole is in petiole mounting hole, the mounting hole end that it is characterized in that described wheel hub is frustoconic shape, the bottom surface radius of the round platform of described mounting hole end is greater than the radius installing hole body, the coupling shaft end of described petiole is also frustoconic shape, and the round platform of described coupling shaft end and the round platform of mounting hole end match.
This scheme discloses a kind of mounting type of blade wheel hub, although achieve the fixing of blade, but when needs are used on cooling tower, due to the existence of cooling water, may some by entering in mounting hole between the gap of wheel hub and blade, but again can not very fast emitting, thus the generation of rusty stain is had after a long time use, even corrosion reduces its working life, thus on inapplicable motor in some water cooling towers, on the other hand, when starting, there is larger stress between blade and wheel hub installation place, thus wheel hub can bear very large pressure, make to be easy to herein deformation occurs, working life can be reduced on the one hand, loosening of blade can be caused on the other hand, impact uses.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of long service life, and blades installation is stablized, the fan wheel hub for cooling tower that drainage effect is good.
For achieving the above object, the utility model provides following technological scheme: a kind of fan wheel hub for cooling tower, described wheel hub is provided with at least three mounting holes, described mounting hole comprises installs hole body and mounting hole end, described installation hole body is interconnected, described wheel hub is extended with in the both sides being positioned at mounting hole end and protrudes from hub inner surface and the radial extension block extended, and described extension block is mesa-shaped.
By adopting technique scheme, by being provided with extension block at hub inner surface, extension block and wheel hub are wholely set and are positioned at both sides, mounting hole end, when installing blade, only corresponding for two pieces of wheel hubs installation bolt need be fixed, the existence of extension block adds the gap between wheel hub, current can automatically be discharged after entering into wheel hub, extension block also serves the structural strength strengthening mounting hole end simultaneously, makes it not easily deformation occur, and strengthens stability during blade rotation.
Of the present utility modelly to be set to further: described hub relative is provided with stiffening rib in the other end of extension block, and described stiffening rib comprises the two piece stiffening rib as corresponding with extension block and the stiffening rib b of connection strengthening rib a.
By adopting technique scheme, increase the structural strength of wheel hub at the other end of mounting hole end by being provided with stiffening rib.
Of the present utility modelly to be set to further: described wheel hub outer side wall is provided with perisporium, and described perisporium is arranged towards stiffening rib direction.
By adopting technique scheme, the pressure that perisporium can well disperse mounting hole to bear, also increases the structural strength of whole wheel hub indirectly.
Of the present utility modelly to be set to further: the installation shaft that described wheel hub is connected with motor shaft is provided with the stiffening plate be connected with wheel hub end face.
By adopting technique scheme, stiffening plate increases the bending resistance shape between installation shaft and wheel hub, increases structural strength.
The utility model has following advantage: arrange by extension block the gap increased on the one hand between wheel hub, makes easy draining, increases the structural strength of mounting hole simultaneously, not easily deformation occurs, extend its working life.
