Background
In many industrial fields, large high-speed horizontal spiral centrifuges are widely applied, and a feed pipe of the centrifuges is broken, which is one of common faults of the centrifuges. The main causes of frequent breakage of the feed tube of the centrifuge are the following: in the first situation, the length of the feeding pipe is continuously lengthened along with the increasing of the major diameter of the centrifuge, the mounting mode of the feeding pipe of the centrifuge generally adopts a cantilever mode, the longer the feeding pipe is, the poorer the rigidity is, when the rigidity of the feeding pipe is insufficient, the feeding pipe is transmitted by the vibration generated when the centrifuge runs, the other end of the feeding pipe can swing to a large extent, and when the swing amplitude exceeds the safety clearance between the feeding pipe and the rotating part of the centrifuge, the feeding pipe can be cut off or abraded by the rotating part; in the second situation, residual liquid exists in the horizontal decanter centrifuge, and the centrifuge is started due to the residual liquid, so that the whole centrifuge vibrates greatly in a short time until the residual liquid is uniformly distributed again under the action of centrifugal force, and in the period, an originally safe feeding pipe is excited to vibrate together to be cut off; in the third situation, after the rotation precision of the centrifuge is lost, when the vibration value during the operation of the centrifuge reaches or exceeds the allowable value, the feeding is easy to cause vibration to cause pipe breakage. The above conditions are likely to be simultaneous when the centrifuge is operating.
The attached fig. 1 and 2 show structural schematic diagrams of a rigidly fixed feeding pipe in the prior art, the feeding pipe 1 is rigidly fixed on the supporting seat 2, and vibration generated during the operation of the centrifuge is transmitted to the feeding pipe 1 from the supporting seat 2, so that the swing amplitude of a cantilever section L of the feeding pipe is too large, and the safe distance S1 between the feeding pipe 1 and a material distribution port 3 of the centrifuge and the safe distance S2 of an end cover spindle 4 are not enough, thereby generating friction. The conventional methods for solving the above problems include: firstly, the diameter of a feeding pipe is increased, the rigidity of the feeding pipe is enhanced, and the swing amplitude during vibration is reduced; secondly, the safe distance between the feeding pipe and the material distribution port of the centrifugal machine and the main shaft of the end cover is enlarged, so that the friction is reduced. However, the method is limited by the internal structure of the centrifuge, the change size is limited, and the phenomenon that the feeding pipe is scratched due to vibration can not be completely and effectively avoided.
