Large-tonnage waste incineration feeding system

The utility model discloses a large-tonnage waste incineration feeding system and relates to the field of waste incineration equipment. The large-tonnage waste incineration feeding system comprises an upper hopper and a lower hopper. The lower hopper is connected to the lower end of the upper hopper, a bridge cracking device is arranged on one side of the lower hopper, a temperature sensor is installed in the lower hopper, and a plurality of fireproof water spraying devices are evenly distributed on one side of the lower hopper in the horizontal direction. Each fireproof water spraying device comprises a water spraying pipe, wherein the outlet end of the water spraying pipe extends into the lower hopper and is connected with a conical nozzle. The large-tonnage waste incineration feeding system is provided with the bridge cracking device, when the waste bridge phenomenon occurs, hydraulic cylinders on the two sides of the lower hopper drive a panel to overturn and compress waste accumulated in the hoppers in a bridging mode. The large-tonnage waste incineration feeding system is provided with the fireproof water spraying devices, when the temperature sensor arranged in the lower hopper detects that the temperature in the hoppers is higher than a set highest temperature, the fireproof water spraying devices are turned on to spray water to reduce the temperature in the hoppers.
