Hanging device for film type wall heating surface

Abstract

The invention discloses a hanging device for a film type wall heating surface. The device comprises a plurality of hanging rods which are arranged on the top part of the film type wall heating surface, wherein the top part of each hanging rod is supported to a bearing support, and the lower end of each hanging rod is connected to the film type wall heating surface; a connecting structure between each hanging rod and the bearing support comprises a spring seat of which the bottom part is fixedly provided with a supporting bottom plate; the supporting bottom plates are supported to the top partof the bearing support; through mounting holes are formed in the supporting bottom plates and the bearing support; the upper ends of the hanging rods penetrate the mounting holes in the bearing support and the supporting bottom plates and extend out of the spring seats; the hanging rods in the spring seats are sleeved with disc springs; pressing plates are arranged on the top parts of the disc springs; and locking nuts are arranged on the hanging rods at the upper parts of the pressing plates. The device has the advantages of being stable to support, and supporting displacement allowance to awaste heat boiler body in thermal expansion and cold contraction, so that the accident that a film type wall is heated and cracked can be avoided, and as a result, the service life of the film type wall heating surface is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of membrane wall waste heat boilers, in particular to a hanging device for a membrane wall heating surface. Background technique [0002] At present, the hanging device on the heating surface of the membrane wall is rigidly connected to the bearing bracket. The disadvantage of rigid connection is that after long-term operation of the waste heat boiler, the thermal expansion of the waste heat boiler will cause rigid displacement of the hanging device, which will cause the membrane water wall to be pulled and cracked. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a hanging device for the heating surface of the membrane wall, which can effectively absorb the displacement caused by thermal expansion, thereby providing reliable support for the heating surface of the membrane wall. [0004] In order to solve the above problems, the technical solutio...

AI Technical Summary

Problems solved by technology

The disadvantage of rigid connection is that after the waste heat boiler has been in operation for a long time, the thermal expansion of the waste heat boiler will cause rigid displacement of the hanging device, which will cause the membrane water wall to be pulled apart.
