[0022] The bottom of the accommodating chamber is semicircular in shape, and discharge ports 12 are provided on both sides of the bottom of the accommodating chamber. A blocking mechanism is provided at the discharge port 12 for closing and opening the discharge port 12 .
[0023] In this embodiment, specifically, the blocking mechanism includes a telescopic rod 13, which is fixed on both sides of the material receiving box 1 to perform corresponding telescopic operations; a connecting plate 14, which is fixed between the two telescopic rods 13 and is located below the material receiving box 1, and its position relative to the bottom of the material receiving box 1 is adjusted with the telescopic adjustment of the telescopic rod 13; a blocking member 15, which is fixed on the fixed plate, matches the discharge port 12 and corresponds one-to-one with the discharge port 12, and rises and falls synchronously with the connecting plate 14, enters and exits the discharge port 12, and opens or blocks the discharge port 12.
[0024] In order to install and fix the receiving box 1, a fixing edge 16 can be set at the top edge of the receiving box 1. The fixing edge 16 has fixing holes 2 for corresponding installation and fixing operations. The fixing holes 2 at the four corners of the fixing edge 16 can fix the receiving box 1 at the slag discharge outlet of the incinerator to receive the discharged slag. Example 2
