Currently, gasification furnaces are commonly used to process hazardous waste, including crushing. However, current gasification furnaces are prone to material jamming during operation, and the jammed material is difficult to remove, impacting production.

[0003] Therefore, there is an urgent need to provide a crushing mechanism for a hazardous waste gasification furnace that can easily solve the problem of material jamming in order to overcome the above-mentioned defects. Utility Model Content

[0021] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] like Figure 1 As shown, this utility model discloses a crushing mechanism 100 for a hazardous waste gasification furnace, mainly used for processing hazardous waste, such as medical waste and toxic and harmful chemical waste. The crushing mechanism 100 is connected to the furnace body of the gasification furnace, and the crushed waste falls into the furnace body for combustion. This utility model mainly improves the crushing mechanism, and its structure will be described in detail below.

[0023] like Figures 1 to 4 As shown, the crushing mechanism 100 of the hazardous waste gasification furnace of this utility model includes a housing 10, a motor 20, a reducer 30, and a crushing shaft 40. The housing 10 has a crushing chamber 11, and the top and bottom of the housing 10 are respectively provided with a feeding port 12 and a discharge port 13 communicating with the crushing chamber 11. The crushing shaft 40 is rotatably mounted on the housing 10, passing through the crushing chamber 11. Two sets of crushing shafts 40 are arranged side-by-side on the housing 10, one on the left and one on the right, with a spacing between them. The crushing shafts 40 can slide and adjust in the left-right direction on the housing 10, thereby adjusting the distance between the two crushing shafts 40. The crushing shaft 40 includes a mounting part 41 located in the crushing chamber 11, and the mounting part 41 is equipped with multiple crushing blades 42. Preferably, the multiple crushing blades 42 are arranged in a circle on the mounting part 41, with equal spacing between each pair of crushing blades 42. The input end of the reducer 30 is connected to the output end of the motor 20, and the crushing shaft 40 is connected to the output end of the reducer 30. The reducer 30 adopts an existing structure and uses a suitable transmission ratio to make the crushing shaft 40 rotate at an appropriate speed.

[0024] In operation, the crushing mechanism 100 of the hazardous waste gasification furnace of this utility model allows hazardous waste to be fed into the feeding port 12. The motor 20 drives the reducer 30 to rotate, which in turn drives the crushing shaft 40 to rotate. The two sets of crushing shafts 40 rotate in opposite directions, and the crushing blades 42 break up and crush the hazardous waste. The broken up and crushed waste is discharged from the discharge port 13. When material jamming occurs, the crushing shaft 40 is operated to slide left and right on the casing 10, increasing the distance between the two sets of crushing shafts 40, allowing the jammed waste to fall naturally, thereby solving the material jamming problem. Moreover, the entire process does not require starting the furnace, improving the convenience of solving the problem of material jamming in the furnace.

[0025] Preferably, the crushing shaft 40 can be driven to slide in the left and right directions by electric drive.

[0026] like Figures 1 to 4As shown, the crushing mechanism 100 of the hazardous waste gasification furnace of this utility model further includes a rotating base 14 that is slidably mounted on the housing 10 in the left-right direction, and a crushing shaft 40 that is rotatably mounted on the rotating base 14. The rotating base 14 supports the crushing shaft 40, and the position of the crushing shaft 40 can be easily adjusted by moving the rotating base 14. Further, a sliding groove 15 extending in the left-right direction is provided on the housing 10, and the rotating base 14 is slidably mounted on the sliding groove 15. The sliding groove 15 guides the movement of the rotating base 14, improving the smoothness of the sliding of the rotating base 14. Preferably, the crushing shaft 40 is rotatably mounted on the rotating base 14 via bearings.

[0027] like Figures 1 to 4 As shown, the crushing mechanism 100 of the hazardous waste gasification furnace of this utility model also includes a baffle 50. Structural extensions 16 are formed outwards on both the left and right sides of the casing 10. Each structural extension 16 has a structural cavity 161 connected to the crushing chamber 11. The baffle 50 is inserted into the structural cavity 161 and fills it. After the baffle 50 is inserted into and fills the structural cavity 161, waste cannot enter the structural cavity 161, thus avoiding affecting the crushing of the waste. Specifically, the baffle 50 includes a mounting plate 51, a connecting body 52, and a baffle plate 53. The left and right ends of the connecting body 52 are connected to the mounting plate 51 and the baffle plate 53, respectively. The connecting body 52 and the baffle plate 53 are inserted into the structural cavity 161. The baffle plate 53 is positioned close to the crushing chamber 11. The mounting plate 51 is installed on the structural extension 16 and seals the structural cavity 161. The structural cavity 161 is designed to increase the volume of the crushing cavity 11, making it easier for crushed waste to pass through and reducing the occurrence of waste jamming. However, at the same time, it can also easily cause waste to accumulate in the structural cavity 161. Therefore, according to actual production needs, the baffle 50 can be inserted into the structural cavity 161.

[0028] Preferably, the mounting plate 51 is roughly square, and the connector 52 consists of two pieces, one above the other, providing sufficient structural stability. After the mounting plate 51 seals the structural cavity 161, it prevents waste and dust from overflowing.

[0029] Furthermore, the baffle plate 53 has an arc-shaped bent structure, and the baffle plate 53 bends and arches towards the mounting plate 51 to adapt to the spatial changes of the crushing chamber 11. The baffle frame 50 is detachably installed on the structural extension 16. The baffle frame 50 can be installed on the structural extension 16 or removed from the structural extension 16 according to the actual situation.

[0030] like Figures 1 to 4 As shown, the crushing chamber 11 is narrow at both ends and wide in the middle, providing space to accommodate the two crushing shafts 40 and facilitating the faster passage of crushed waste, thus avoiding material jamming.

[0031] like Figures 1 to 5 As shown, the crushing mechanism 100 of the hazardous waste gasification furnace of this utility model also includes a cooling device for cooling the crushing shaft 40, which is located inside the crushing shaft 40. Since the gasification furnace operates at very high temperatures, the cooling device cools the crushing shaft 40, thus protecting it. Specifically, the cooling device includes a cooling water pipe 60. The crushing shaft 40 has a liquid flow chamber 43, and the cooling water pipe 60 passes through the liquid flow chamber 43. One end of the cooling water pipe 60 is connected to the liquid flow chamber 43, and one end of the crushing shaft 40 is connected to a connector 44. The connector 44 has an inlet 441 and an outlet 442 connected to the liquid flow chamber 43. The outlet 442 is connected to the liquid flow chamber 43, and the other end of the cooling water pipe 60 is connected to the inlet 441. By injecting a cooling solution (such as water) into the cooling water pipe 60, the cooling solution flows out of the cooling water pipe 60 and into the liquid flow chamber 43. After heat exchange, it carries away the heat from the installation part 41 and the broken blade 42. The heated cooling solution flows out from the outlet 442. This continuous circulation can continuously cool the installation part 41.

[0032] The following is a brief description of the working process of the crushing mechanism 100 of the hazardous waste gasification furnace of this utility model: The motor 20 is started, and hazardous waste is fed into the feeding port 12. The crushing shaft 40 rotates, driving the crushing blades 42 to rotate, crushing the hazardous waste. The crushed hazardous waste is then discharged from the discharge port 13. When material jamming occurs, the crushing shaft 40 is driven to slide left and right on the casing 10, increasing the distance between the two sets of crushing shafts 40, allowing the jammed waste to fall naturally, thus resolving the jamming problem.
