The utility model discloses an energy-saving treatment device for
coal gasification
slag processing, which relates to the technical field of
slag treatment devices and comprises an energy-saving
slag treatment box, a feeding bin is arranged at the top of the energy-saving slag treatment box, a rotating shaft is movably sleeved at one end of the energy-saving slag treatment box, and a driving motor is arranged at one end of the rotating shaft. Through mutual cooperation of the screen
barrel, the fixed connecting plate, the cleaning
brush, the feeding opening, the double-shaft crushing rolling shaft, the fixed block and the inclined baffle, the problem that the
machining efficiency of the device is affected due to the fact that an existing crushing mechanism cannot completely crush residues is solved, the crushing and screening functions are achieved, rolling crushing is conducted through the double-shaft crushing rolling shaft, and the crushing efficiency is improved. And through cooperation with screening holes of the screening
barrel for screening and cooperation with rotation of the screening
barrel, the inclined baffle drives the residues to move to the top and fall to the top of the double-shaft smashing rolling shaft again for smashing till screening is passed, and complete smashing of the device is facilitated.
