[0014] Because this utility model adopts the above-mentioned technical solution, its positive effects compared with the prior art are as follows:
[0015] By applying this utility model, a highly durable slag dumping well is provided. The buffer device can protect the main structure of the slag dumping well from the impact damage of slag for a long time, thereby reducing the shutdown caused by damage to the slag dumping well during operation.

[0021] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".
[0022] like Figure 1The diagram shows a preferred embodiment of a high-durability slag discharge well, comprising: a well body 100, with a slag inlet at the upper end and a slag outlet at the lower end; a chute, disposed at the lower end of the well body 100 and connected to the slag outlet; and a buffer device 200, disposed on the inner wall of the well body 100, with a buffer plane at the upper end of the buffer device 200.
[0023] Furthermore, as a preferred embodiment, it also includes a slag discharger, which is preferably located at the slag discharge port to prevent the slag discharge port from being blocked by falling slag. Furthermore, the chute is preferably inclined along the horizontal plane, as this inclined arrangement facilitates better flow of the falling slag towards the slag discharge port.
[0024] Furthermore, in a preferred embodiment, the buffer device 200 includes: a heat insulation component 210, a heat-resistant component 220, and a top plate 230. The heat-resistant component 220 is disposed around the outer side of the heat insulation component 210, and the top plate 230 is disposed at the upper end of the heat-resistant component 220. A buffer plane is formed on the upper surface of the top plate 230. Further, the buffer device 200 is used to buffer the slag 400 entering the slag discharge well 400 to prevent the slag 400 from directly impacting the well body 100 and the chute.
[0025] Furthermore, as a preferred embodiment, the heat insulation component 210 includes: a support frame 211 and a plurality of heat insulation plates 212, wherein the support frame 211 is connected to the inner wall of the well body 100, and the plurality of heat insulation plates 212 are arranged around the support frame 211.

[0028] Furthermore, as a preferred embodiment, the top plate 230 is formed by a plurality of second refractory bricks or an integrally cast structure. Furthermore, the upper surface of the top plate 230 has the aforementioned buffer plane.
[0029] Furthermore, as a preferred embodiment, the buffer plane extends horizontally.
[0030] Furthermore, as a preferred embodiment, it also includes: a heat insulation layer 300, which is disposed on the inner wall of the well body 100. Furthermore, the heat insulation layer 300 is used to prevent the slag 400 from causing high-temperature damage to the internal structure of the well body 100, further increasing the durability of the slag 400 well.
[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model.
[0032] Based on the above, this utility model also has the following embodiments:
[0033] In a further embodiment of this utility model, the high-durability slag discharge well 400 needs to be used in conjunction with an external mechanical grate furnace, which is used to convey slag 400 to the slag inlet of the high-durability slag discharge well 400.
[0034] In a further embodiment of this utility model, when the external mechanical grate furnace is running, the ash 400 generated by waste incineration falls onto the buffer device 200. The ash 400 gradually accumulates on the upper surface of the top plate 230 and gradually forms a conical accumulation body under the action of gravity. During the operation of the ash 400 well, the sharp corner of the top of the conical accumulation body can continuously receive the impact of the ash 400 to achieve secondary buffering of the buffer device 200. Furthermore, stones, bricks, and high-temperature coking materials mixed in with domestic waste are all buffered by the conical accumulation body to reduce their damage to the buffer device 200 and the well body 100.
[0035] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
