Although the slag granulation mechanism of the smelting furnace (publication number CN220386469U) can filter and recycle water, its filtration efficiency is low and it lacks the function of conveying slag to the outside, which means that manual cleaning is still required, resulting in low work efficiency. Utility Model Content

[0010] Furthermore, it also includes a slag removal assembly, which is located inside the housing. The slag removal assembly includes a servo motor, propeller blades, and a slag removal pipe, wherein:

[0011] The servo motor is fixedly installed on the outer wall of the housing, the propeller blade is fixedly connected to the output end of the servo motor and is located inside the housing, the propeller blade is located on the top of the filter plate, and the slag discharge pipe is fixedly connected to the outer wall of the housing and communicates with the inside of the housing.

[0012] Furthermore, the filter plate is arranged with higher sides and lower middle, and the bottom of the filter plate is arc-shaped.

[0013] Furthermore, a filter plate is fixedly connected between the inner walls of the box, the filter plate is located at the bottom of the filter cake plate, and the bottom of the box is inclined.

[0014] The beneficial effects of this utility model after adopting the above structure are as follows:

[0015] (1) The air inlet can be connected to the equipment that outputs high-speed saturated steam, and the liquid injection pipe can be connected to the external high-pressure water source to spray high-pressure water. The slag can be effectively crushed by the uniform rotation of the crushing teeth and the setting of the fixed teeth.

[0024] like Figure 1-2 As shown, a furnace slag granulation mechanism includes a housing 1. The top of the housing 1 is provided with an air inlet 2, a feeding pipe 16 and a liquid injection pipe 17. The top of the side wall of the housing 1 is provided with a pressure relief valve 3 to prevent excessive air pressure inside the housing 1. The bottom of the side wall of the housing 1 is provided with a drain pipe 4. The bottom of the housing 1 is inclined to facilitate liquid drainage. It also includes a slag treatment component, a separation component and a slag discharge component. The slag discharge component is located inside the housing 1. The slag treatment component and the separation component are both located inside the housing 1.

[0025] The slag is granulated by the slag processing component, and the slag and water are efficiently separated by the separation component. The slag is then conveyed and discharged by the slag discharge component.

[0026] like Figure 1-4 As shown, in order to granulate the slag, the slag processing assembly includes a rotary motor 5, a central shaft 6, crushing teeth 7, and fixed teeth 8. The rotary motor 5 is fixedly installed on the top of the housing 1. The central shaft 6 is fixedly connected to the output end of the rotary motor 5 and is located inside the housing 1. The central shaft 6 and the housing 1 are coaxially arranged. The crushing teeth 7 are fixedly connected to the central shaft 6 and are evenly distributed. The fixed teeth 8 are fixedly connected to the inner wall of the housing 1 and are staggered. The slag can be crushed into small particles by the cooperation of the rotating crushing teeth 7 and the fixed teeth 8.

[0027] like Figure 1-4 As shown, in order to efficiently separate slag and water, the separation assembly includes a filter plate 9, a waterproof box 10, and a vibration motor 11. The filter plate 9 is fixedly connected between the inner walls of the housing 1, the waterproof box 10 is fixedly connected to the bottom of the filter plate 9, and they are symmetrically distributed. The vibration motor 11 is fixedly installed inside the waterproof box 10. The vibration motor 11 drives the filter plate 9 to vibrate, thereby separating the slag and water that fall on the filter plate 9.

[0028] like Figure 1-4As shown, in order to facilitate the discharge of slag, the slag discharge assembly includes a servo motor 12, a propeller blade 13, and a slag discharge pipe 14. The servo motor 12 is fixedly installed on the outer wall of the housing 1. The propeller blade 13 is fixedly connected to the output end of the servo motor 12 and is located inside the housing 1. The propeller blade 13 is located on the top of the filter plate 9. The slag discharge pipe 14 is fixedly connected to the outer wall of the housing 1 and communicates with the inside of the housing 1. The filter plate 9 is set with high sides and low middle. The bottom of the filter plate 9 is arc-shaped and adapted to the propeller blade 13. The slag is transported by the rotation of the propeller blade 13 and discharged through the slag discharge pipe 14.

[0029] In order to perform preliminary filtration of the water after use, a filter plate 15 is fixedly connected between the inner walls of the tank 1. The filter plate 15 is located at the bottom of the filter cake plate 9, and the filter plate 15 can be an activated carbon filter plate.

[0030] In practical use, the air inlet 2 is connected to an external device that outputs high-speed saturated steam, and the liquid injection pipe 17 is connected to an external high-pressure water source to spray high-pressure water. An appropriate amount of slag is added into the box 1 through the feeding pipe 16. Then, the rotary motor 5 is turned on, and the uniform rotation of the crushing teeth 7, combined with the setting of the fixed teeth 8, can efficiently crush the slag. After crushing, the water and slag are mixed and fall onto the filter plate 9. Then, the vibration motor 11 is turned on, and the filter plate 9 efficiently filters the water and slag. During the filtration process, the shape design of the filter plate 9 can concentrate the slag in the propeller blade 13. The wastewater falls onto the filter plate 15 through the filter plate 9, and the filter plate 15 can purify the filtered wastewater. It is then discharged through the drain pipe 4 through the inclined bottom of the box 1. Finally, the servo motor 12 is turned on, and the rotation of the propeller blade 13 can uniformly transport the slag. The slag can be collected centrally through the slag discharge pipe 14, avoiding the problem of low efficiency caused by manual operation.
