Description

Technical Field

[0001] This utility model relates to the field of lithium ore roasting rotary kiln technology, specifically to a slag discharge device for a lithium ore roasting rotary kiln. Background Technology

[0002] In the actual production and operation of a rotary kiln for lithium ore roasting, the smoothness of the slag discharge process directly affects the efficiency and stability of the entire production process.

[0003] In the lithium ore roasting process, the rotary kiln slag discharge device is a key link affecting production efficiency and stability. Traditional slag discharge methods mostly use gravity discharge or scraper conveying. However, due to the strong adhesion and easy agglomeration of lithium slag at high temperatures, it often leads to blockage of the slag discharge port, affecting continuous production and even requiring frequent shutdowns for cleaning, increasing maintenance costs. In addition, a large amount of high-temperature waste heat is generated during the lithium ore roasting process. If this waste heat is directly discharged, it will not only cause a huge waste of energy, but also does not conform to the current concept of energy conservation, emission reduction and green production.

[0004] Therefore, a slag discharge device for a lithium ore roasting rotary kiln is proposed to solve the problems mentioned above. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 4 This embodiment discloses a slag discharge device for a lithium ore roasting rotary kiln, including a slag discharge pipe 1. A slag discharge mechanism is installed inside the slag discharge pipe 1. This mechanism uses a spiral rod 36 to discharge slag evenly and effectively, avoiding slag blockage that can occur with other methods. A waste heat absorption mechanism is installed at the bottom of the slag discharge pipe 1 to absorb waste heat, improving the practicality of the slag discharge device. The slag discharge mechanism includes a mounting plate 32, which is fixedly installed on the side of the slag discharge pipe 1. The mounting plate 32 is used to support the installation of a motor 31. The bottom of the mounting plate 32 is fixedly installed with the motor 31, which has forward and reverse rotation functions. The motor 31 is configured to drive the first gear 33 to rotate. The first gear 33 is fixedly installed at the bottom of the motor 31. The first gear 33 is configured to mesh with the second gear 37. The side of the slag discharge pipe 1 is rotatably connected to the shaft 35 through the bearing. One end of the shaft 35 passes through the slag discharge pipe 1 and is fixedly installed with the spiral rod 36. The spiral rod 36 is configured to discharge slag evenly. The other end of the shaft 35 is fixedly installed with the first conveyor wheel 34. The second gear 37 is fixedly installed on one side of the first conveyor wheel 34. The second gear 37 meshes with the first gear 33. By configuring the first gear 33 and the second gear 37, the motor 31 drives the shaft 35 to rotate when it is working.

[0026] The waste heat absorption mechanism includes a recovery box 22, which is fixedly installed at the bottom end of the slag discharge pipe 1. The recovery box 22 is set up to store water. An inlet pipe 23 is fixedly installed on the recovery box 22, and an outlet pipe 26 is fixedly installed on the surface of the recovery box 22.

[0027] Mounting plate 32 is horizontally set and is square in shape. Mounting plate 32 is set to support the installation of motor 31.

[0028] The motor 31 is vertically positioned, the first gear 33 is a bevel gear and is horizontally positioned, and the second gear 37 is a bevel gear and is vertically positioned.

[0029] The shaft 35 is cylindrical in shape and is horizontally positioned for mounting the helical rod 36.

[0030] A rotating rod 25 is rotatably connected to the inner wall of the recycling box 22. The rotating rod 25 is horizontally set and is cylindrical in shape. The rotating rod 25 is set to support the installation of the stirring blade 27.

[0031] A stirring blade 27 is fixedly installed on the rotating rod 25. The stirring blade 27 is used to stir the water in the recovery tank 22, which helps the water to fully absorb the residual heat. One end of the rotating rod 25 passes through the recovery tank 22 and is fixedly installed with a second conveyor wheel 21. The second conveyor wheel 21 is set vertically.

[0032] The first transmission wheel 34 and the second transmission wheel 21 are meshed with a track 24. The track 24 is vertically arranged. With the first transmission wheel 34, the second transmission wheel 21 and the track 24 arranged, when the shaft 35 rotates, it drives the rotating rod 25 to rotate.

[0033] When slag needs to be discharged from the lithium ore roasting rotary kiln, the motor 31 is started. The motor 31 drives the first gear 33 to rotate. The first gear 33 meshes with the second gear 37, which in turn drives the first conveyor wheel 34 to rotate. When the first conveyor wheel 34 rotates, it drives the shaft 35 to rotate. When the shaft 35 rotates, it drives the screw rod 36 to rotate. When the screw rod 36 rotates, it evenly transports the residue in the slag discharge pipe 1 out of the slag discharge pipe 1.

[0034] Furthermore, during the slag discharge process, the first conveyor wheel 34 will drive the second conveyor wheel 21 to rotate via the track 24. When the second conveyor wheel 21 rotates, it will drive the rotating rod 25 to rotate. When the rotating rod 25 rotates, it will drive the stirring blade 27 to rotate. When the stirring blade 27 rotates, it will stir the water in the recovery box 22, so that the water can fully absorb the temperature of the slag discharge pipe 1.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
