DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0022] Please refer to Figures 1-4This utility model provides a technical solution for drying waste heat material from pre-melted refining slag: It includes a slag box 1 and a drying cylinder 2 positioned above the slag box 1. Air inlet pipes 11 are symmetrically arranged on both sides of the slag box 1, and a heat-conducting cylinder 13 is also installed inside the slag box 1. Fixing plates 14 are symmetrically arranged on both sides of the heat-conducting cylinder 13 inside the slag box 1. A speed-reducing plate 141 is fixed to the upper surface of the fixing plate 14. A second heat-conducting rod 16 is symmetrically arranged on one side of the fixing plate 14 inside the slag box 1. An air pump 4 is also installed on the upper surface. The air outlet of the air pump 4 is connected to a connecting pipe 41. A stirring motor 3 is also installed on the upper surface of the drying cylinder 2. This setup utilizes the first heat-conducting rod 15, the heat-conducting cylinder 13, and the heat-conducting adhesive on its inner side to conduct the residual heat of the slag to the interior of the drying cylinder 2, thereby drying the material inside the drying cylinder 2. The air pump 4 can also draw in external air and heat it by contacting the hot air generated by the slag, thereby drying the material inside the drying cylinder 2 with the hot air. It is practical.

[0023] like Figure 2 and Figure 3 As shown, the speed reduction plate 141 has symmetrical speed reduction holes on its outer side, and the upper surface of the speed reduction plate 141 is fixed to the inner upper surface of the slag box 1, while the lower surface of the fixing plate 14 is fixed to the inner lower surface of the slag box 1. This arrangement uses the speed reduction holes on the outer side of the speed reduction plate 141 to reduce the air velocity, thereby allowing better contact with the hot air generated by the slag to achieve heating, which is convenient for subsequent drying of the material.

[0024] like Figure 2 and Figure 3 As shown, at least three second heat-conducting rods 16 are symmetrically arranged inside the slag box 1. Slag is placed inside the slag box 1 on one side of the fixed plate 14 near the air inlet pipe 11. This arrangement uses the second heat-conducting rods 16 to conduct the heat of the accumulated slag, so as to better contact the incoming air and achieve the purpose of heating the air.

[0025] like Figure 3 As shown, the inner side of the heat-conducting cylinder 13 is provided with heat-conducting adhesive. The lower end of the drying cylinder 2 is embedded in the interior of the heat-conducting cylinder 13 and contacts the exterior of the heat-conducting adhesive. A first heat-conducting rod 15 is installed on the outer side of the fixing plate 14. One end of the first heat-conducting rod 15 penetrates the inner side of the heat-conducting cylinder 13 and is embedded in the interior of the drying cylinder 2. This arrangement uses the first heat-conducting rod 15 to transfer the heat of the slag to the interior of the drying cylinder 2. The heat inside the slag box 1 can be conducted to the drying cylinder 2 through the heat-conducting cylinder 13 and the heat-conducting adhesive to achieve the purpose of drying the material inside.

[0026] like Figure 3As shown, the air inlet of the air pump 4 is connected to a fixed pipe inside the slag box 1, and one end of the connecting pipe 41 is connected to a nozzle 42 inside the drying cylinder 2. This setup uses the fixed pipe to extract heated air, and the nozzle 42 connected through the connecting pipe 41 can transfer heat to the inside of the drying cylinder 2 for heating purposes.

[0027] like Figure 1 As shown, a feed pipe 21 is provided on the outside of the drying cylinder 2, and the outside of the drying cylinder 2 is covered with a heat insulation sleeve 22. This arrangement allows the material to be dried to be introduced into the cylinder through the feed pipe 21, and the heat insulation sleeve 22 is used to keep the drying cylinder 2 warm.

[0028] like Figure 4 As shown, the drive end of the stirring motor 3 is connected to a rotating shaft 31. From top to bottom, a first stirring rod 32 and a second stirring rod 33 are respectively arranged on the outside of the rotating shaft 31. A third stirring rod 34 is symmetrically arranged between the first stirring rod 32 and the second stirring rod 33 on the outside of the rotating shaft 31. A connecting rod 341 is symmetrically arranged on the outside of the third stirring rod 34. This arrangement utilizes the operation of the stirring motor 3 to make the rotating shaft 31 rotate, thereby causing the first stirring rod 32 and the second stirring rod 33 on the outside of the rotating shaft 31 to stir the material inside. At the same time, when rotating, the connecting rod 341 on the outside of the third stirring rod 34 also stirs the material, thus avoiding the accumulation of material and affecting drying.

[0029] The working principle of this utility model is as follows: When using the pre-melted refining slag waste heat material drying equipment, firstly, the box plate on the slag box 1 can be opened to pour the refining slag into the interior of the slag box 1. After pouring, it should be positioned below the air inlet pipe 11, and then the box plate should be closed. At the same time, the material to be dried should be introduced through the feed pipe 21 and then the feed pipe 21 should be closed. When drying the material, the external air can be drawn in by starting the air extraction pump 4 to contact the heat of the slag and heat it. The heat of the slag can also be discharged through the second heat-conducting rod 16 to contact the incoming air. This allows heated air to be introduced into the drying cylinder 2 through the connecting pipe 41 and the nozzle 42 to dry the material. It is practical. At the same time, the first heat-conducting rod 15, the heat-conducting cylinder 13 and the heat-conducting adhesive on its inner side can conduct heat to the inside of the drying cylinder 2 to achieve the purpose of drying the material. During the drying process, the rotating shaft 31 will rotate when the stirring motor 3 is working, and the first stirring rod 32, the second stirring rod 33 and the third stirring rod 34 will rotate to efficiently stir the material inside the drying cylinder 2 to achieve the purpose of efficient drying and avoid the accumulation of material, which would affect the drying effect.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
