By adopting technique scheme, blade detachable interposing is connected on after on connecting shaft block, and blade radial is fixed, then connecting shaft block is threaded with plectane, blade is arranged on plectane together with connecting shaft block simultaneously, makes blade axial restraint; Therefore the utility model half-opened impeller has detachable function, simultaneously, because blade and connecting shaft interblock are that inserting mode is connected, and be threaded that can to realize institute vaned fixing by a connecting shaft block, historical facts or anecdotes existing the utility model half-opened impeller does not need the dismounting of a blade blade when dismantling, get final product manual teardown blade after only needing dismounting connecting shaft block, and screw thread quantity during dismounting greatly reduces, and makes the utility model half-opened impeller change blade convenient, quick.
The utility model is set to further: the side of described connecting shaft block is provided with joint, described joint is provided with the chute that the axial direction along connecting shaft block is arranged, one end of joint is run through in one end of described chute, the end face and the connecting shaft block that described joint run through end are provided with the end face of tapped hole in the same way, the side of described blade is provided with fixture block, described fixture block is located at the end of blade, one end that described blade is provided with fixture block insert joint chute and by the radial stator blade of fixture block.
By adopting technique scheme, the joint that connecting shaft block is provided with chute is used for connecting blade, on blade, arrange card makes the blade radial location be plugged on joint realize the detachable grafting of blade one connecting shaft block simultaneously soon, makes the convenient disassembly of blade and connecting shaft interblock.
The utility model is set to further: the tapped hole that one end end face of described connecting shaft block is provided with, described connecting shaft block is provided with end face that the end face of tapped hole and joint upper hopper chute run through in the same way, described plectane is provided with and tapped hole one_to_one corresponding through hole, and after described connecting shaft block is connected with plectane, the blade be arranged on connecting shaft block is connected on plectane.
By adopting technique scheme, plectane and connecting shaft interblock are bolted solid and reliable, and use the connection of this structure can not form protruding structure to affect the using effect of impeller on plectane end face.
The utility model is set to further: the end face that described connecting shaft block is provided with tapped hole is also provided with locating bump, and described plectane is provided with and described locating bump positioning groove one to one.
By adopting technique scheme, positioning groove being established by plectane, connecting shaft block establishes locating bump, make connecting shaft block when mounted more accurately, conveniently.
The utility model is set to further: the end that the end face that described joint upper hopper chute runs through and connecting shaft block mulberry are provided with tapped hole is coplanar, and the length of described chute equals the height of blade.
By adopting technique scheme, increase the length of joint upper hopper chute, so increase blade is connected with joint after area of contact, the connection making blade and connecting shaft block is stablized more, firm.
The utility model is set to further: described fixture block is strip, and described fixture block length equals the height of blade.
By adopting technique scheme, fixture block is set to strip and fixture block length equals blade height, this structure strengthens the ability to bear of fixture block, avoids the too small blade that makes of fixture block to be connected insecure with connecting shaft block.
In sum, the utility model half-opened impeller has the advantage of easy accessibility.
