Abstract
The invention discloses a horizontal centrifuge preventing feed from flowing backwards. The horizontal centrifuge cannot generate the backflow phenomenon and separate solid and liquid. The horizontal centrifuge comprises a rotating shaft, a bottom plate and a rotating body. The middle of the rotating body is connected with the bottom plate, and a material cavity is formed between the rotating body and the bottom plate. Threads are arranged on the outer wall of the rotating body in the axial direction, the outer side of the rotating body is wrapped by a revolving drum, the head of the rotating body is connected with a discharging hopper communicated with the interior of the rotating body, and a feeding pipe is arranged at the upper end of the discharging hopper. The lower end of the feeding pipe stretches into the discharging hopper to be bent and then stretches into the material cavity horizontally, an opening of the end, stretching into the material cavity, of the feeding pipe is in a horn shape and is provided with a semispherical guiding plate, and a horn-shaped channel is formed between the guiding plate and the feeding pipe. The horizontal centrifuge has the advantages that the outlet of the feeding pipe is arranged to be in the horn shape, materials are in a radial shape when being sprayed out, the flow velocity is reduced, and the materials can directly enter the revolving drum after aligning with a through hole, and therefore the phenomenon of backflow can be avoided to the maximum.
