Title:
CONNECTION PART STRUCTURE OF SOLID MATTER TRANSPORT PIPE
Document Type and Number:
Japanese Patent JP2017180572
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To restrict partial wear under a less-expensive manner.SOLUTION: This invention relates to a connection part structure at a curved portion of a transport pipe passage for solid material in which several transport pipes P are through flanges F, F at their ends. A tongue piece 11 made of anti-wear material covering a part of the transport pipes P of the curved portion that is easily worn out at a front side in a transporting direction is arranged at an inner side end surface of the flange F continuous to an inner surface of the transport pipe P to be protruded inward from its end surface. With this arrangement as above, since solid material does not reach the part which can be easily worn out, that part will not be worn out in an eccentric manner. It is possible that the tongue piece 11 is arranged at a ring 10 present between both opposing flanges F, F at the connection part or can be arranged directly at the flange F. A hardening padding may also be applied to an inner peripheral surface of the ring 10 or an inner peripheral surface of the flange F. When the tongue piece 11 is arranged at the ring, if the to connected tongue piece is worn out or damaged, entire ring 10 is replaced. In this way, when the eccentric wear at the pipe passage is restricted only through a replacement of the ring 10, it is possible to extend a life of the entire pipe passage.SELECTED DRAWING: Figure 1
