AI Technical Summary
After the ash slag produced after the incineration furnace is mixed with cold slag water, some of the ash slag with greater viscosity is prone to be plated at the tail of the slag conveying channel, resulting in a decrease in the area of the slag conveying channel and a large resistance, which affects the normal slag output of the slag remover.

Description
Technical Field
[0001] The utility model relates to the technical field of slag scooping machines, in particular to a slag scooping machine outlet anti-caking device. Background Art
[0002] After the incinerator burns garbage, the slag enters the slag remover and is mixed with cold slag water for cooling. After being pushed by the pusher head inside the slag remover, the slag is transported to the slag storage for discharge. Since the slag generated after the incinerator burns garbage is mixed with cold slag water, some of the slag with higher viscosity becomes larger as the tail opening of the slag conveying channel becomes larger. During the process of reducing the flow velocity and friction force, the slag is compacted at the corners on both sides of the tail opening of the slag conveying channel. The compacted slag has high hardness and is difficult to clean manually. As the amount of compaction increases, the area of the slag conveying channel decreases, and the slag conveying resistance is large, which affects the normal slag discharge of the slag remover. In view of the above shortcomings, the present invention is based on the existing equipment structure and a stainless steel inclined plate is added at the place where the slag conveying channel of the slag remover is prone to compaction. After adding the stainless steel inclined plate, the contact angle and the smoothness of the metal surface are increased to inhibit compaction.
