Technical Field

The invention belongs to the technical field of centrifuges, and particularly relates to a horizontal spiral discharging sedimentation centrifuge with a squeezing baffle structure.

Background

For solid-phase materials with soft compressibility, a general horizontal spiral discharging sedimentation centrifuge adopts a large cone angle (15-20 degrees) and a squeezing baffle structure, the centrifuge adopts a single vertical squeezing baffle to separate separation liquid and separation slag at two sides, the squeezing baffle adopts a single annular plate welded in the middle of a spiral channel to separate the spiral channel, the squeezing baffle plays a role in squeezing solids and separating liquid, and simultaneously the effective volume of the centrifuge can be greatly increased by matching with the large cone angle structure, namely the processing capacity of the centrifuge is improved. However, because dead angles exist among the squeezing baffle, the helical blades and the helical shaft, a large amount of solid accumulated materials can be stored in the dead angles in the working process of the centrifugal machine, and the centrifugal machine is difficult to clean thoroughly in the cleaning process. When long-term accumulation of some food materials can produce the phenomenon of smelling and deteriorating simultaneously, can destroy centrifuge's dynamic balance when long-term the distribution is inhomogeneous, leads to centrifuge operation in-process vibration grow. Therefore, a horizontal spiral discharge sedimentary centrifuge capable of solving the existing problems is urgently needed.
