The alternator belt continues to be thrown even after tightning the alternator. You can replace the belt, tighten the alternator and it may stay on several days but eventually comes off again
It must be that one of the pulleys is out of line or mishaped, although it could be that a shaft bearing on one of the pulley shafts is bad and causing it to vary in tightness as it rotates.I would try rotating all the pulleys to see if one is wobbling.

I had mine replaced and all it did was "sqeal" like a pig!
A different brand of belt was the fix!
