The utility model relates to a sludge feeding uniform distributor for an incinerator. The uniform distributor comprises an incinerator top feeding opening (2) and an auger conveyor (1) which is driven by a horizontal motor (6), wherein a stainless steel uniform distributing plate (3) in the shape of a circular arc with an opening upwards is fixed on the incinerator top feeding opening (2); a plurality of uniformly distributed holes (31) are formed on the stainless steel uniform distributing plate; a rotary shaft (5) of the auger conveyor (1) is evenly and fixedly provided with a plurality of outwards extending connecting rods (51) in the circumferential direction; a stainless steel scraper (4) is fixedly arranged at the outer end of each connecting rod; the stainless steel scrapers (4) are positioned in the stainless steel uniform distributing plate (3); and the outer ends of the stainless steel scrapers are not contacted with the stainless steel uniform distributing plate (3). The sludge feeding uniform distributor for an incinerator changes large wet sludge blocks falling on the stainless steel uniform distributing plate into small blocks through the stainless steel scrapers arranged on the rotary shaft of the auger conveyor, so that sludge is burnt fully, thereby ensuring the normal operation of production. In addition, the sludge feeding uniform distributor for an incinerator has simple structure and low cost, and is suitable for popularization and application in the industry.
