[0024] With respect to this specific embodiment, during specific use, the material to be incinerated enters the furnace body 101 through the feed port 105, and after being guided by the feed hopper 103, falls on the upper surface of the sprinkling and crushing cone 109, and the reduction motor 107 is started, and the sprinkling and crushing cone 109 is driven to rotate through the drive shaft 108, so that the material is subjected to centrifugal motion on the sprinkling and crushing cone 109, and the material is crushed and scattered after passing through the first crushing component, the second crushing component and the third crushing component in turn, and is sprinkled at the combustion section of the furnace body, so that the material layer thickness distribution is more even, which is conducive to incineration, prevents the phenomenon of burning through the material layer or smoldering due to uneven thickness, and improves the incineration treatment effect of the material.

[0025] Furthermore, a mounting flange 110 is provided at the center of the material-sprinkling and crushing cone 109 , and one end of the driving shaft 108 away from the reduction motor 107 is connected to the material-sprinkling and crushing cone 109 through the mounting flange 110 .

[0026] According to this specific embodiment, the installation of the material-sprinkling crushing cone 109 and the driving shaft 108 is completed by setting the installation flange 110 .

[0028] According to the present specific embodiment, since each of the first-level main crushing blades 113, each of the second-level main crushing blades 116 and each of the third-level main crushing blades 119 are arranged in the counterclockwise rotation direction of the material-sprinkling crushing cone 109, when the material is sprinkled on the material-sprinkling crushing cone 109, after being fully crushed by the first-level main crushing blade 113, the first-level auxiliary crushing blade 112, the second-level main crushing blade 116, the second-level auxiliary crushing blade 115, the third-level main crushing blade 119 and the third-level auxiliary crushing blade 118 in sequence, the material is evenly distributed in the furnace body 101 under the action of the centrifugal force generated when the material-sprinkling crushing cone 109 rotates. Since the first crushing piece 111, the second crushing piece 114 and the third crushing piece 117 are arranged to be shorter step by step, the first-level main crushing blade 113, the second-level main crushing blade 116 and the third-level main crushing blade 119 arranged along the counterclockwise rotation direction are also arranged in a gradually shorter structure, which is beneficial to the centrifugal crushing and distribution of the material.

[0034] With respect to this specific embodiment, by setting the air inlet 126 and the first air hole 127, gas exchange is carried out between the interior of the furnace body 101 and the outside, which helps to maintain the freshness and fluidity of the gas in the furnace, prevent the accumulation of harmful gases in the furnace, and maintain the stability of the internal gas flow of the furnace body 101, thereby reducing the unstable combustion phenomenon caused by poor airflow. By setting the second air hole 128, the air permeability of the material on the conical surface of the sprinkler and crushing cone 109 is enhanced, thereby promoting the drying reaction.

[0035] Furthermore, a pushing spiral blade 129 is also provided on the outer side wall of the driving shaft 108 , and the pushing spiral blade 129 is arranged inside the feeding hopper 103 .

[0036] According to this specific embodiment, the pushing spiral blades 129 are provided to facilitate the transportation of the material in the feed hopper 103 to the furnace body 101 , and to avoid the clogging and bridging of the material in the feed hopper 103 , thereby ensuring the stability of the equipment operation.

Since each of the first-level main crushing blades 113, each of the second-level main crushing blades 116 and each of the third-level main crushing blades 119 are arranged in the counterclockwise direction of the material sprinkling crushing cone 109, when the material is sprinkled on the material sprinkling crushing cone 109, it is sequentially After being fully crushed by the first-level main crushing blade 113, the first-level auxiliary crushing blade 112, the second-level main crushing blade 116, the second-level auxiliary crushing blade 115, the tertiary main crushing blade 119 and the tertiary auxiliary crushing blade 118, the material is subjected to centrifugal motion on the material-sprinkling crushing cone 109, and the material is crushed and scattered after passing through the first crushing component, the second crushing component and the third crushing component in sequence, and is sprinkled at the combustion section of the furnace body, so that the thickness distribution of the material layer is more uniform, which is conducive to incineration, prevents the phenomenon of burning through the material layer or smoldering due to uneven thickness, and improves the incineration treatment effect of the material.
