Description

Technical Field

[0001] This utility model belongs to the field of rotary kiln technology, and more specifically, it relates to a rotary kiln drying and calcining integrated drying device. Background Technology

[0002] The function is to pre-treat materials for subsequent calcination processes within the same kiln body. This involves removing moisture from the materials through efficient heat exchange, while simultaneously optimizing the physicochemical properties of the materials to ensure calcination quality and efficiency. It addresses the problems of material transfer loss, heat waste, and process disconnect in traditional separate equipment. The existing rotary drum drying and calcination kiln integrated machine (publication number CN221593455U) uses two intersecting propeller blades on the outer edges of two cylinders to crush and break up chemical waste while simultaneously conveying it, avoiding the phenomenon of chemical waste clumping and difficulty in drying. However, it lacks a screening mechanism, making it difficult to screen out larger chemical waste clumps after crushing. Larger chemical waste clumps affect drying efficiency. Therefore, a rotary kiln drying and calcination integrated drying device is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rotary kiln drying and calcining integrated drying device. The crushed chemical waste falls into the hopper through the gaps between the screening rods, and then falls into the feed inlet of the rotary kiln body through the discharge port of the hopper, thereby drying and calcining the chemical waste. This solves the problem mentioned in the background technology of the lack of a screening mechanism, which makes it difficult to screen out larger chemical waste clumps after crushing, and the clumps of larger chemical waste affect the drying efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary kiln drying and calcining integrated drying device, comprising a rotary kiln body and a hopper, a shell fixed to the top surface of the hopper, a first opening on the upper outer side of the shell, a second opening on the lower outer side of the shell, two connecting rods fixed to the inner side of the second opening, and multiple screening rods fixed between the two connecting rods, the multiple screening rods being arranged at equal intervals, two connecting discs symmetrically fixed to the inner side of the shell, and two crushing rollers rotatably connected between the two connecting discs, with both ends of the two crushing rollers passing through... A first gear is coaxially fixed to the outer side of the housing and extends from one side of the connecting disc. Adjacent first gears are meshed together. Two baffles are also fixed between the two connecting discs. Multiple first scrapers are fixed to the opposite side of the two baffles. Rotating grooves are opened on the outer circumference of the two connecting discs. Connecting plates are rotatably connected to the inner side of the rotating grooves. A toothed groove is opened on the inner side of one of the connecting plates. A second gear is meshed to the inner side of the toothed groove. Multiple second scrapers are fixed between the two connecting plates. A motor is fixed to one side of the housing. A third gear is fixed to the output end of the motor.

[0005] As a preferred embodiment of this utility model, the discharge port of the hopper corresponds to the feed port of the rotary kiln body.

[0006] As a preferred embodiment of this invention, the interior of the second opening is connected to the interior of the hopper.

[0007] As a preferred embodiment of this utility model, the centers of the two connecting discs coincide with the center of the shell.

[0008] As a preferred embodiment of this invention, both baffles have an arc-shaped structure on opposite sides.

[0009] As a preferred embodiment of this utility model, both connecting plates are in the form of annular structures, and the centers of the two connecting plates coincide with the centers of the two connecting disks.

[0010] As a preferred embodiment of this utility model, one end of the shaft of the third gear extends through the outer side of the housing to the inner side and is coaxially and fixedly connected to the inner side of the second gear.

[0011] This utility model provides a rotary kiln drying and calcining integrated drying device, which has the following beneficial effects: This rotary kiln drying and calcining integrated drying device allows the crushed chemical waste to fall into the hopper through the gaps between the screening rods, and then into the feed inlet of the rotary kiln body through the hopper's outlet. This process dries and calcines the chemical waste, solving the problem of the lack of a screening mechanism, which makes it difficult to screen out larger clumps of chemical waste after crushing, thus affecting the drying efficiency.

[0012] 2. In this rotary kiln drying and calcining integrated drying device, multiple second scrapers will transport the chemical waste that has passed through the screen back between the two crushing rollers for re-crushing. At the same time, multiple second scrapers will clear the chemical waste that is blocking the screen rods, thus preventing the screen rods from becoming blocked. Attached Figure Description

[0023] Please see Figures 1 to 6This utility model provides a technical solution: a rotary kiln drying and calcining integrated drying device, including a rotary kiln body 1 and a hopper 2. A shell 3 is fixed to the top surface of the hopper 2. A first opening 4 is opened on the upper outer side of the shell 3, and a second opening 5 is opened on the lower outer side of the shell 3. Two connecting rods 6 are fixed to the inner side of the second opening 5. Multiple screening rods 7 are fixed between the two connecting rods 6. The multiple screening rods 7 are arranged at equal intervals. Two connecting discs 8 are symmetrically fixed to the inner side of the shell 3. Two crushing rollers 9 are rotatably connected between the two connecting discs 8. Both ends of the two crushing rollers 9 extend through one side of the connecting discs 8 to the outer side of the shell 3 and are coaxially fixed with a first gear 10. Adjacent first gears 10 are meshed with each other. Two baffles 11 are also fixed between the two connecting discs 8. Multiple first scrapers 12 are fixed to the opposite side of the two baffles 11. Rotating grooves are provided on the outer circumference of the hopper 2. A connecting plate 14 is rotatably connected to the inner side of the rotating groove. A toothed groove 15 is provided on the inner side of one of the connecting plates 14. A second gear 16 is meshed on the inner side of the toothed groove 15. Multiple second scrapers 13 are fixed between the two connecting plates 14. A motor 17 is fixed on one side of the housing 3. A third gear 18 is fixed at the output end of the motor 17. The discharge port of the hopper 2 corresponds to the feed port of the rotary kiln body 1. The interior of the second opening 5 is connected to the interior of the hopper 2. The centers of the two connecting plates 8 coincide with the center of the housing 3. The opposite sides of the two baffles 11 are arc-shaped. The two connecting plates 14 are annular.

The crushed chemical waste falls into the hopper 2 through the gap between the screening rods 7, and then falls into the feed port of the rotary kiln body 1 through the discharge port of the hopper 2, thereby drying and calcining the chemical waste. The motor 17 drives the second gear 16 to rotate through the shaft of the third gear 18. The second gear 16 meshes with the tooth groove 15 on the inner side of the connecting plate 14, thereby driving the connecting plate 14 and multiple second scrapers 13 to rotate. The multiple second scrapers 13 transport the chemical waste that has passed through the screen back to the space between the two crushing rollers 9 for re-crushing. At the same time, the multiple second scrapers 13 clear the chemical waste that is blocking the space between the screening rods 7, preventing the screening rods 7 from becoming blocked. Through the above process, the problem of not having a screening mechanism, making it difficult to screen out larger chemical waste clumps after crushing, and the impact of larger chemical waste clumps on drying efficiency is solved.

[0024] The specific usage and function of this embodiment: This utility model pours chemical waste into the space between two crushing rollers 9 in the shell 3. Then, the motor 17 drives the two crushing rollers 9 to rotate relative to each other through the third gear 18 and the first gear 10, thereby crushing the chemical waste. The crushed chemical waste falls into the hopper 2 through the gap between the screening rods 7, and then falls into the feed port of the rotary kiln body 1 through the discharge port of the hopper 2, thereby drying and calcining the chemical waste. The motor 17 drives the second gear 16 to rotate through the shaft of the third gear 18. The second gear 16 meshes with the tooth groove 15 on the inner side of the connecting plate 14, thereby driving the connecting plate 14 and multiple second scrapers 13 to rotate. The multiple second scrapers 13 transport the chemical waste that has passed through the screen back between the two crushing rollers 9 for re-crushing. At the same time, the multiple second scrapers 13 clear the chemical waste that is blocking the screen rods 7, preventing the screen rods 7 from becoming blocked.
