Disclosed in the present invention is a leak-proof kiln spiral feeder. A gear-type rotary sealing structure composed of a sealing baffle and blades is mounted on a spiral shaft. In this way, a mixed material can be prevented from coming into contact with the portion of a closed end through which the spiral shaft passes, so as to solve the problem of leakage, and the blades rotate to stir the mixed material in a feeding pipe at the closed end to prevent same from caking, so as to facilitate the pushing and carrying away of the mixed material by a spiral blade on the spiral shaft, such that blockage of the feeding pipe caused by excessive moisture content in the mixed material can be avoided. In addition, when the spiral shaft rotates, the blades lift the mixed material up to a certain height, and then the mixed material slides forward along a conical surface, so that auxiliary pushing for the mixed material is realized, and the mixed material slides down to the spiral blade of the spiral shaft to facilitate continuous forward pushing. Furthermore, an opening is provided at the bottom of the feeding pipe and is in communication with a section of circular chute, and a manual ball valve is mounted in the circular chute, so as to facilitate sampling to check the impact of the ratio of moisture in the mixed material on heat consumption and other process problems, thus achieving a certain function of control over monitoring of the process.
