Device for the disaggregation of powdery material in a reservoir

摘要

For the raking and otherwise disaggregation of powdery material in a reservoir chamber, there is provided an agitator unit comprising a laterally extending shaft disposed for rotation in the reservoir on which is mounted a pair of laterally spaced disks with strip lengths or cables stretched between the disks. The cables serve to provide a raking surface which prevents the powdery material from clumping and the agitator unit is rotated in the reservoir. The opposed ends of the cables are connected to the disks by means of clamping devices which are interchangeably disposed in corresponding bores formed along the outer edges of the disks. Each clamping device comprises a bush part having a lateral passage for receiving therethrough a corresponding free end of the cable. The bush is rigidly connected to the free end of the cable by means of a compressed or pinched fit and the bush is secured in the disk bore as the result of suitable stop surface means. A leaf spring plate is secured to the disk to resiliently hold the bush in place in the disk bore. As the result of the clamping device, the likelihood of a tension rupture of the cable is reduced and projecting free ends of the cables are able to be disposed within the area between the disk and the adjacent sidewall of the reservoir.
