[0007] Furthermore, the slag blocking plate comprises a slag blocking plate body, and a plurality of groups of partition rods are evenly distributed on the inner wall of the cavity of the slag blocking plate body.

[0008] Furthermore, the secondary slag blocking assembly includes a secondary slag blocking body fixed to the end of the slag blocking body, the secondary slag blocking body is located at the other end of the slag blocking body relative to the primary slag blocking body, a plurality of groups of permeable holes are evenly distributed on the inner wall of the secondary slag blocking body cavity, and a partition net is provided at one end of the inner wall of the secondary slag blocking body cavity.

[0009] Furthermore, the separation net is embedded in one end of the secondary slag blocking body cavity, and a locking wrench for fixing the separation net is provided on the side wall of one end of the secondary slag blocking body.

[0010] Beneficial effects: The utility model has reasonable design, simple and stable structure, strong practicality, and has the following beneficial effects:

[0011] 1. The setting of the primary slag blocking assembly can drive the coordination between the components by driving the cylinder to change the gap between each set of slag blocking plates, so as to cope with the use of larger residue sizes in different usage scenarios;
