[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model; Reference Figures 1-5 A refractory material raw material drying device includes a drying barrel 1, several movable frames 4 are rotatably installed inside the drying barrel 1, air pipes 7 are connected to both sides of the drying barrel 1, upper feed component 15 and lower feed component 16 are installed on the inner top surface of the drying barrel 1 and are in contact with each other, and a bottom box 8 is fixedly installed at the bottom of the drying barrel 1, and a screen plate 11 and a downwardly inclined discharge plate 23 are installed inside the bottom box 8.

[0016] A feed inlet 2 is fixedly installed on the top of the drying barrel 1. A cover 3 is rotatably installed on the top of the feed inlet 2. A rotating rod 19 is rotatably installed inside the drying barrel 1. Several movable frames 4 are fixedly connected to the outer surface of the rotating rod 19. The other side of each movable frame 4 is in contact with the inner surface of the drying barrel 1. Several transverse dividing rods 5 are fixedly connected to the inner surface of the movable frame 4. The rotating rod 19 drives the movable frame 4 to rotate inside the drying barrel 1. The transverse dividing rods 5 improve the turning efficiency of the raw materials. The movable frame 4 continuously scrapes the inner wall of the drying barrel 1 to prevent the raw materials from sticking to the inner wall of the drying barrel 1.

[0017] The upper feed component 15 is fixedly connected to the inner top surface of the drying barrel 1, and the upper feed component 15 is rotatably connected to the outer surface of the rotating rod 19. The upper surface of the lower feed component 16 is rotatably connected to the lower surface of the upper feed component 15, and the surfaces of the upper feed component 15 and the lower feed component 16 are provided with corresponding through grooves 17. The lower feed component 16 is coaxially fixedly connected to the rotating rod 19. The upper surface of the upper feed component 15 is equipped with a scraper 18 that is coaxially fixedly connected to the rotating rod 19. The lower feed component 16 and the scraper 18 rotate synchronously with the rotating rod 19. When the lower feed component 16 rotates until the upper and lower through grooves 17 overlap, a fixed amount of raw material falls from the upper feed component 15 into the lower drying barrel 1 for drying, avoiding the situation where too much material is fed per unit time, causing the raw material inside the drying barrel 1 to accumulate and not dry thoroughly.

[0018] An air pump 6 is fixedly installed on the upper surface of the bottom box 8. Two air pipes 7 are fixedly connected to the two sides of the air pump 6 respectively. A filter screen 14 is fixedly installed at the end of the air pipe 7. The drying barrel 1 is connected to the air pump 6 through the air pipe 7. The air pump 6 blows air to dry the raw materials inside the drying barrel 1 through the air pipe 7. The filter screen 18 can prevent the raw materials from entering the air pipe 7 and affecting the drying process.

[0019] The bottom of the drying barrel 1 is provided with several feeding troughs 9. The drying barrel 1 is connected to the bottom box 8. A dual-shaft motor 20 is fixedly installed on the outer bottom surface of the drying barrel 1. The upper rotating shaft of the dual-shaft motor 20 is coaxially fixedly connected to the rotating rod 19. The lower rotating shaft of the dual-shaft motor 20 is coaxially fixedly connected to the first bevel gear 21.

[0020] Inside the bottom box 8, a connecting rod 12 is rotatably mounted. A second bevel gear 22 that meshes with the first bevel gear 21 is coaxially fixedly mounted on the outer surface of the connecting rod 12. Several cams 13 are fixedly mounted on the outer surface of the connecting rod 12. When the cams 13 rotate to the vertical position, they contact the upper surface of the sieve plate 11.

[0021] The first bevel gear 21 drives the second bevel gear 22 to rotate, causing the cam 13 to continuously strike the surface of the sieve plate 11 to sieve the dried raw materials above it.

[0022] The front surface of the bottom box 8 is provided with a discharge port 10. The inner bottom surface of the discharge port 10 is fixedly connected to the bottom of the discharge inclined plate 23, and the top of the discharge inclined plate 23 is fixedly connected to the lower surface of the screen plate 11. The raw materials after screening are discharged from the discharge inclined plate 23 for centralized collection.

[0023] Working principle: In this refractory material raw material drying device, the crushed raw material is poured into the feed port 2. The feed piece 16 and scraper 18 rotate synchronously with the rotating rod 19. When the feed piece 16 rotates to the point where the upper and lower through slots 17 overlap, a fixed amount of raw material falls from the upper feed piece 15 into the drying barrel 1 below for drying. This avoids excessive material feeding per unit time, which would cause raw material to accumulate inside the drying barrel 1 and result in incomplete drying. The rotating rod 19 drives the moving frame 4 to rotate inside the drying barrel 1. The horizontal dividing rod 5 improves the turning efficiency of the raw material. The moving frame 4 continuously scrapes the inner wall of the drying barrel 1 to prevent the raw material from sticking to the inner wall of the drying barrel 1. The air pump 6 blows air to dry the raw material inside the drying barrel 1 through the air pipe 7. The filter screen 18 can prevent raw material from entering the air pipe 7 and affecting the drying process. The first bevel gear 21 drives the second bevel gear 22 to rotate, so that the cam 13 continuously hits the surface of the screen plate 11 to screen the dried raw material above it. After screening, the raw material is discharged from the discharge inclined plate 23 for centralized collection.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
