Description

Technical Field

[0001] The utility model relates to the technical field of deaerator installation, and specifically relates to a support structure. Background Technique

[0002] The deaerator mainly consists of two major components, namely the deaerator tower head and the deaerator water tank, as well as connecting pipes and external accessories. Its main component, the deaerator, is composed of a shell, a steam-water separator, a new type of film-forming device, a water spraying grid, a heat storage packing liquid-vapor network and other components. The principle of the deaerator is that the make-up water is sprayed out in a spiral shape at a certain angle through the film-forming pipe for heat exchange with the heating steam to remove oxygen. The feed water is heated to the saturation temperature corresponding to the working pressure of the deaerator to remove the oxygen and other gases dissolved in the feed water, preventing and reducing the corrosion of the boiler feed water pipes, economizers and other auxiliary equipment. The deaerator is supported and installed through a support structure, which is an important part for supporting and transmitting loads.

[0003] Chinese Patent Publication No. is CN220453179U, and the authorized announcement date is February 6, 2024. A support seat structure includes a support assembly.

Four shock-absorbing assemblies are provided inside the fixed seat. The shock-absorbing assemblies are connected to the moving seat through the locking assembly. The shock-absorbing assembly includes a hydraulic buffer body. The top of the lifting rod of the hydraulic buffer body is fixedly connected with a plug rod. When the utility model is in use, the moving seat is inserted into the fixed seat, the plug rod is inserted into the slot, the lead screw drives the gear to rotate self, the annular rack meshed with the outside of the gear drives the arc-shaped clamping block to rotate and is inserted into the four clamping slots, thereby fixedly connecting the moving seat and the plug rod. The vibration generated by the motor is transmitted to the hydraulic buffer body through the moving seat and the plug rod. The second spring and the hydraulic buffer body dissipate the vibration force to shock-absorb the motor. Reverse rotation of the gear causes the arc-shaped clamping block to disengage from the clamping slot, and the moving seat disengages from the fixed seat.
