Three-dimensional compensator special for pulverized coal

Abstract

The invention relates to a three-dimensional compensator special for pulverized coal. The three-dimensional compensator comprises a corrugated pipe assembly I, a corrugated pipe assembly II, a lining pipe I, a lining pipe II, a connection pipe I, a connection pipe II, and a connection pipe III, wherein each corrugated pipe assembly comprises a corrugated pipe, the connection pipe II, an annular plate, a lug plate, a nut and a pull rod, two ends of the corrugated pipe are connected with the annular plate and the lug plate through the connection pipe II respectively, the annular plate is connected with the pull rod and the lug plate through the nut, one end of the corrugated pipe assembly I is connected with the connection pipe I, one end of the corrugated pipe assembly II is connected with the connection pipe III, the corrugated pipe assembly I is connected with the corrugated pipe assembly II through an intermediate connection pipe, the connection pipe I is connected with the lining pipe I which is connected with the intermediate connection pipe, and the intermediate connection pipe is connected with the lining pipe II which is connected with the connection pipe III. The three-dimensional compensator is special applicable to pulverized coal conveying pipelines, the deflection angle displacement amount and the axial displacement amount of the compensator are large, and large displacement produced when a pipeline device is operated can be effectively compensated and absorbed; the three-dimensional compensator is simple in structure, practical, long in service life, and convenient to manufacture, install, and maintain.

Description

technical field [0001] The invention relates to the technical field of pipeline compensators, in particular to a three-dimensional bellows compensator specially used for pulverized coal conveying pipelines. Background technique [0002] At present, industries such as electric power, building materials, and heat generally need to install and use three-dimensional pipeline compensators in pipelines. The three-dimensional pipeline compensator usually has a spherical compensator and a bellows compensator. The three-dimensional compensator can perform radial angular displacement and axial linear displacement. It has a large deflection angle and a large axial displacement, which can effectively compensate and absorb boilers and other equipment. The larger amount of displacement generated at runtime. The three-dimensional bellows compensators installed in existing power plants and cement plants are generally designed for flue gas or pulverized coal pipelines. The structure of the ...

AI Technical Summary

Problems solved by technology

The three-dimensional bellows compensators installed in existing power plants and cement plants are generally designed for flue gas or pulverized coal pipelines. The structure of the three-dimensional pipeline compensators is relatively complicated, and it is inconvenient to manufacture and install. The three-dimensional bellows compensators use three to five Leakage is prone to occur within one year, so the compensator must be replaced, resulting in a short service life of the compensator, heavy maintenance and replacement workload, and high cost
