Issue 32/2014 - Three technical achievements of Shenhua Guoshen Group have obtained national patents

Recently, the three technical achievements of Shenhua Guoshen Group Dianta Power Generation Company: "manual plucking device", "boiler slag device" and "centering adjustment device of motor coupling" have been authorized
by the State Intellectual Property Office for utility model patents.

The manual pin pulling device uses the principle of mechanical movement to pull out the positioning pin; The slag device of the boiler uses seamless pipes, welds and installs some devices to control the hidden dangers of non-stop or reduced power caused by boiler slag plugging; The centering adjustment device of the motor coupling "is to realize the random adjustment
of the motor in four directions by installing hanging ears and making special tools.

The above patented technology is mainly used for the disassembly of the pin shaft when the equipment with pins is overhauled and disassembled; Dredging of boiler ash, cinder, gangue pipes; In the field of
mechanical overhaul technology.
The device is reasonably designed, flexible and easy to
operate.
These patented technologies are all practical technologies invented by front-line employees in production practice, and are the vivid practice
of Shenhua Group's technological innovation work.
The application of these practical achievements in production practice has obvious effects and good effects
