[0022] Referring to Figure 1 and Figure 2 , the embodiment provides a spiral conveyor for conveying steel balls,

[0023] An ash collection bin is additionally arranged at the bottom of the spiral blade of the spiral conveyor, and is close to the discharge port of the spiral conveyor. The ash collection bin is used for collecting the ash falling from the steel balls moving in the spiral blade. The inner shell of the ash collection bin is drilled with a plurality of small holes for collecting the ash so as to enter the collection bin at the bottom.

[0024] The spiral conveyor is used for conveying the steel balls falling from the waste heat boiler. The steel balls enter from the feeding port of the spiral conveyor, pass through a plurality of spiral blades, and then fall from the discharge port of the spiral conveyor. The spiral conveyor is arranged at the bottom of the waste heat boiler. The feeding port of the spiral conveyor is aligned with the steel ball falling port of the waste heat boiler. The steel balls fall into the bucket elevator after flowing out of the discharge port of the spiral conveyor. The bucket elevator is used for lifting and conveying the steel balls to the top of the waste heat boiler, so that the steel balls are recycled. The spiral conveyor comprises a shell, and a plurality of spiral blades are horizontally arranged in the shell. The shell and the spiral blades are made of wear-resistant steel plates. The distance between adjacent spiral blades is less than 100 mm.

[0025] It should be noted that the embodiment is an improvement on the basis of the ordinary spiral conveyor. The conventional spiral conveyor comprises a motor, a speed reducer, a head bearing, a head packing box, a shell, a feeding port, spiral blades, a discharge port, a tail packing box, and a tail bearing. The connection relationship of the above components can be obtained without doubt on the basis of referring to Figure 1 , because the conventional spiral conveyor is prior art, and the connection relationship thereof is not described herein.

[0026] Specifically, in operation, first, the material of the housing, the screw blade and other components of the screw conveyor are made of wear-resistant steel plate to prevent equipment wear during operation, the speed ratio of the reducer is large to reduce the prototype speed of the screw conveyor, prevent the steel ball from bouncing, the distance L of the screw blade is smaller than that of the ordinary screw conveyor blade, generally L < 100 mm, a furnace ash collecting bin is arranged in front of the tail discharge port, and the internal housing is drilled to collect ash, because the steel ball after cleaning will carry part of the furnace ash, when the screw conveyor is running, the furnace ash falls from the hole into the collecting bin, and finally the cleaned steel ball is discharged from the discharge port into the bucket elevator, and the process is completed.

[0027] The specific embodiments of the present application are described above. It should be understood that the present application is not limited to the specific implementation described above, and one or more of the above embodiments can be combined to form a combined embodiment. Those skilled in the art can make various changes or modifications or combinations within the scope of the claims, which does not affect the essential content of the present application. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined arbitrarily.
