[0002] Steel slag activators are additives used to activate the potential activity of steel slag and improve its hydration reaction ability. They are commonly used in engineering fields such as steel slag-based cementitious materials, building materials, or soil solidification.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 7As shown in the figure, this utility model embodiment provides a uniform drying device for steel slag activator, including a first tank 1, a feeding hopper 2, a lifting screw 3, a stirring rack 4, a rotating mechanism 5, a hot air conveying device 6, a second tank 7, a vibrator 8, and a frame 9. The first tank 1 has an inner cylinder 11 inside, and a lifting channel 110 is provided in the middle of the inner cylinder 11. The feeding hopper 2 is connected to the bottom of the lifting channel 110. The feeding hopper 2 is used to convey the steel slag activator to the bottom of the lifting channel 110. The lifting screw 3 is located in the lifting channel 110. The top of the lifting channel 110 is provided with a discharge port 111. The lifting screw 3 is used to convey the steel slag activator in the lifting channel 110 from the discharge port 111 to the inner cylinder 11. The stirring rack 4 is located in the inner cylinder 11. The stirring rack 4 is used to disperse the steel slag activator at the bottom of the inner cylinder 11. The rotating mechanism 5 is connected to the lifting screw 3 and the... The mixing frame 4 is connected by a transmission. The bottom of the inner cylinder 11 is provided with a discharge port 112. The discharge port 112 is provided with a butterfly valve 113. The bottom of the butterfly valve 113 is connected to the second tank 7 through a connecting pipe 114. The bottom of the second tank 7 is connected to the frame 9 through a spring assembly 71. The upper part of the second tank 7 is provided with a screening plate 72. The screening plate 72 is used to receive the steel slag activator conveyed from the discharge port 112. The vibrator 8 is provided on the side wall of the second tank 7. The vibrator 8 is used to drive the screening plate 72 to vibrate. The hot air conveying device 6 includes a hot air generator 61, a first air duct 62 and a second air duct 63. The hot air generator 61 is used to generate hot air and is connected to the first air duct 62 and the second air duct 63. The air outlet end of the first air duct 62 extends into the inner cylinder 11, and the air outlet end of the second air duct 63 extends into the second tank 7 below the screening plate 72.The steel slag activator is conveyed from the feeding hopper 2 to the bottom of the lifting channel 110. The rotating action of the lifting screw 3 lifts the material upwards from the bottom of the lifting channel 110 and conveys it to the inner cylinder 11 through the discharge port 111. The lifting screw 3 effectively prevents material agglomeration while lifting the material. The stirring rack 4 disperses the steel slag activator at the bottom of the inner cylinder 11, preventing material sedimentation and improving material flowability, thereby enhancing the contact efficiency between the material and hot air. After the steel slag activator is stirred, dispersed, and dried in the inner cylinder 11, the butterfly valve 113 opens, allowing the material to enter the second tank 7. The vibrator... Vibration can evenly spread the material on the screening plate 72, thereby promoting the drying efficiency of the material and avoiding the impact of material accumulation on the drying efficiency. During this process, the hot air conveying device 6 can generate hot air through the hot air generator 61 and convey the hot air to the inner cylinder 11 through the first air duct 62 to dry the material in the inner cylinder 11. The second air duct 63 can convey the hot air to the second tank 7 to dry the material on the screening plate 72. With this configuration, the drying effect of the steel slag activator is effectively improved through the dual action of two-stage hot air conveying and dispersion, preventing material accumulation and improving the drying uniformity.

[0038] like Figure 3 As shown, the inner cylinder 11 is further provided with a conical structure 100 at the bottom, and the discharge port 112 is located on the conical structure 100. This arrangement allows the material to slide on the conical structure 100 at the bottom of the inner cylinder 11, avoiding the accumulation of material at the bottom and effectively improving the flowability of the material. At the same time, the conical structure 100 can also guide the material into the discharge port 112.

[0039] like Figure 5 and Figure 6As shown, the rotating mechanism 5 further includes a drive motor 51, a gear sleeve 52, a first gear disc 53, a second gear disc 54, and a rotating disk 55; the first gear disc 53 is connected to the top of the lifting screw 3, the rotating disk 55 is sleeved on the outside of the lifting screw 3 and can rotate relative to the lifting screw 3, the bottom of the rotating disk 55 is connected to the stirring frame 4, and the top is connected to the second gear disc 54. The drive motor 51 is located at the bottom of the first tank 1, its output shaft is arranged downwards, and it is connected to the gear sleeve 52. The surface of the gear sleeve 52 has a first tooth groove portion 521 and a second tooth groove portion 522. The first tooth groove portion 521 is meshed with the first gear disc 53, and the second tooth groove portion 522 is meshed with the second gear disc 54. When the drive motor 51 rotates, it can drive the gear sleeve 52 to rotate through its output shaft, which in turn drives the first gear disk 53 and the second gear disk 54 to rotate. When the first gear disk 53 rotates, it can drive the lifting screw 3 to perform a vertical lifting motion, so as to send the steel slag activator from the lifting channel 110 into the inner cylinder 11. When the second gear disk 54 rotates, it can drive the bottom stirring frame 4 to perform a stirring action through the rotating disk 55, thereby dispersing and stirring the steel slag activator at the bottom of the inner cylinder 11 and preventing material accumulation.

[0040] like Figure 3 and Figure 5 As shown, the bottom of the stirring rack 4 is provided with a slanted rod 41, which is located above the surface of the conical structure 100, so that the stirring rack 4 can fully contact the material during the stirring process and improve the stirring and dispersing effect.

[0041] like Figure 6 As shown, the second toothed portion 522 further includes a toothed portion 5221 and a non-toothed portion 5222, the arc length of which is greater than that of the toothed portion 5221. During the stirring process, when the toothed portion 5221 meshes with the second toothed disc 54, the power transmitted by the drive motor 51 can be transmitted to the second toothed disc 54, thereby driving the stirring frame 4 to rotate, thus realizing the stirring and dispersion of the material; however, when the second toothed portion 522 rotates to the non-toothed portion 5222, the meshing contact between the toothed portion 5221 and the second toothed disc 54 is broken. At this time, the second toothed disc 54 cannot rotate, and the stirring frame 4 also stops rotating, thereby realizing the periodic stirring of the material, allowing the material sufficient time to stand and dry, thus improving the drying effect.

[0042] Furthermore, both the first duct 62 and the second duct 63 are flexible hoses, so that the first duct 62 and the second duct 63 can adapt to the vibration of the equipment and deform accordingly.

[0043] like Figure 7As shown, the second tank 7 is further provided with a discharge port 70 at the bottom, which is used to discharge the dried steel slag activator.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
