So, only need wash the grate bar through washing subassembly 10 and can realize clearing up the stifled grate bar that pastes, compare in artifical clearance, labour saving and time saving, efficiency is higher.

It should be explained that the liquid impacts to primarily clean the grate bar adhesive, and the liquid flowing through the blockage can dissolve alkali metal substances in the adhesive, and meanwhile, the liquid can moisten the sinter stuck in the middle of the grate bar, and the free calcium oxide in the sinter reacts with the liquid to increase the volume, so that the strength is reduced, and the free calcium oxide in the sinter automatically falls off. Under the action of the three physical and chemical processes, the adhesive on the grate bars can fall off, thereby achieving the purpose of cleaning the grate bars.

In some embodiments, the wash assembly 10 includes a liquid supply for providing a cleaning medium, a wash pump connected between the liquid supply and the wash conduit for pumping the cleaning medium within the liquid supply to the wash conduit, and a wash conduit disposed above the trolley 200 for spraying the cleaning medium toward the grate bars.
