Detailed Description

The present invention will be further described with reference to the following specific examples.

As shown in figure 1, the high-temperature grate cooling device for the garbage pyrolysis furnace comprises a grate 1, a circulating water pump 2 and a circulating water tank 3. Grate 1 is including the hopper 11 that is used for loading rubbish and being used for driving 11 rotatory pivots 12 of hopper, the axial direction who follows pivot 12 in the pivot 12 runs through the rivers passageway 4 of pivot 12, and pivot 12 vertical fixation is inside hopper 11, the bottom of pivot 12 leads to pipe 5 and connects circulating water pump 2, the bottom and the water pipe 5 intercommunication of rivers passageway 4, circulating water pump 2 leads to pipe 5 and connects circulating water tank 3, circulating water tank 3 leads to pipe 5 and connects the top of pivot 12, the top and the water pipe 5 intercommunication of rivers passageway 4, the water that circulating water pump 2 extracts in the circulating water tank 3 leads to pipe 5 and follows the top of rivers passageway 4 bottom from rivers passageway 4, 5 refluences to the circulating water tank in 3 of rethread water pipe.

In the above embodiment, the bottom end and the top end of the rotating shaft 12 are detachably connected with the water pipe 5 through the rotary connector 6, so as to facilitate the detachment and installation of the water pipe 5 and the rotating shaft 12. In this embodiment, the rotating shaft 12 is a seamless steel pipe, the number of the fire grates 1 is two, and the water pipe 5 is divided into the water flow channels 4 in the rotating shaft 12 of the two fire grates 1, so that the utilization rate of the water flow can be improved. In other embodiments, there may be more than one grate 1, and the water pipes 5 may be branched to the water flow passage 4 in the rotating shaft 12 of each grate 1.
