[0024] In this embodiment, the feeding device 2 can deliver materials to the interior of the furnace body 1. The motor 204 can drive the connecting rod 205 fixedly connected by the coupling to rotate. The connecting rod 205 drives the spiral blade 206 to rotate, so that the material can be transported to the discharge port 203, which is convenient for the staff to operate, saves the labor of the staff, and improves the work efficiency. The filtering component 3 is used to filter the generated waste slag, which is convenient for cleaning the waste slag without affecting the working environment.
