Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum fluoride material drying, specifically to an aluminum fluoride material drum drying device. Background Technology
[0002] Aluminum fluoride is an important inorganic compound widely used in metallurgy, chemical industry, building materials, electronics and other fields. For example, in the aluminum smelting process, it is often used as a flux in electrolytic aluminum to lower the melting point and increase the conductivity of the electrolyte, thereby improving the purity and yield of aluminum. Drying is an important production step in the production of aluminum fluoride. Currently, rotary drum drying equipment, also known as a drying rotary kiln, is commonly used to dry aluminum fluoride materials. The rotation of the rotary kiln, combined with hot air, achieves the drying effect.
[0003] However, inside the rotary kiln, although the aluminum fluoride material can be dispersed as the kiln rotates, the degree of dispersion is too low, and some aluminum fluoride material will still accumulate together. Therefore, it is necessary to further improve the dispersion effect of the aluminum fluoride material so that it can come into more sufficient contact with the hot air and achieve a better drying effect. Utility Model Content

[0007] Furthermore, the stirring assembly also includes a cavity formed inside the stirring rod. A connecting cylinder is installed at the end of the stirring rod away from the motor. A connecting pipe is fixedly connected to the end of the connecting cylinder away from the stirring rod. An air pump is connected to the end of the connecting pipe away from the connecting cylinder. One end of the air pump is connected to the ventilation chamber through a docking part.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, the docking component is a rectangular frame, and an air guide cavity is provided inside the docking component. The air guide cavity is connected to the interior of the ventilation chamber through a perforation, and one end of the air pump is connected to the interior of the air guide cavity through a pipe.
[0010] Furthermore, the branch rod is designed to be hollow, and an air outlet is opened on the side wall of the branch rod. The branch rod communicates with the cavity through the exhaust port opened on the stirring rod.
[0011] Furthermore, a protrusion is fixedly installed at one end of the side wall of the stirring rod.

[0026] Please see Figure 1 , Figure 2 and Figure 3 A rotary drum drying device for aluminum fluoride materials includes a mounting frame 1. A drum 2 is mounted on the top of the mounting frame 1. The drum 2 includes a rotating cylinder 201, a discharge cylinder 202, and a feeding cylinder 203. The rotating cylinder 201 is driven by a gear on its outer wall, which meshes with a transmission gear. The transmission gear is driven by a stepper motor 604 mounted on the mounting frame 1. A feeding funnel 3 is mounted on the top of the feeding cylinder 203. A discharge pipe 5 is mounted on the bottom of the discharge cylinder 202. A hot blower 4 is mounted on one end of the feeding cylinder 203. A ventilation chamber 14 is provided between the hot blower 4 and the discharge cylinder 202. The hot air blown by the hot blower 4 enters the inner cavity of the drum 2 through the ventilation chamber 14 to dry the material in the inner cavity of the drum 2.
[0027] The drum 2 is equipped with a stirring assembly 6, which includes a motor 604, a stirring rod 601, and a branch rod 603. The motor 604 is mounted on the side wall of the discharge pipe 5, and one end of the stirring rod 601 is fixedly connected to the output end of the motor 604. The branch rod 603 is fixedly mounted on the side wall of the stirring rod 601. The direction in which the motor 604 drives the stirring rod 601 to rotate is opposite to the direction in which the drum 201 rotates. When the motor 604 is started, it drives the stirring rod 601 to rotate, and the branch rod 603 located on the stirring rod 601 will rotate accordingly, thereby stirring the material inside the drum 201 to disperse the material and allow the dispersed material to come into more thorough contact with the hot air.
[0028] Please see Figure 2 and Figure 3 The stirring assembly 6 in this embodiment also includes a cavity 602 formed inside the stirring rod 601. A connecting cylinder 9 is installed at the end of the stirring rod 601 away from the motor 604. A connecting pipe 11 is fixedly connected to the end of the connecting cylinder 9 away from the stirring rod 601. An air pump 12 is connected to the end of the connecting pipe 11 away from the connecting cylinder 9. One end of the air pump 12 is connected to the ventilation chamber 14 through a docking part 13.
[0029] The docking part 13 is a rectangular frame. An air guide cavity is provided inside the docking part 13, and the air guide cavity is connected to the interior of the ventilation chamber through a perforation. One end of the air pump 12 is connected to the interior of the air guide cavity through a pipe.
[0030] The branch rod 603 is designed to be hollow, and an air outlet 8 is opened on the side wall of the branch rod 603. The branch rod 603 communicates with the cavity 602 through the exhaust port 7 opened on the stirring rod 601.
[0031] The air pump 12 extracts hot air through the docking part 13, allowing the hot air to enter the connecting cylinder 9 through the connecting pipe 11, then enter the cavity 602 of the stirring rod 601 through the connecting cylinder 9, then enter the branch rod 603 through the cavity 602, and finally be discharged from the air outlet 8 on the branch rod 603.
[0032] Please see Figure 2 and Figure 3 In this embodiment, a protrusion 10 is fixedly installed on one end of the side wall of the stirring rod 601. The protrusion 10 is designed as an annular shape, and the end of the protrusion 10 away from the stirring rod 601 is movably engaged with the inner wall of the connecting cylinder 9. The protrusion 10 is movably fitted with the annular groove opened in the inner wall of the connecting cylinder 9.
[0033] The branch rod 603 is designed in a rectangular shape, and the air outlet 8 is located on the side wall of the branch rod 603. The branch rods 603 are arranged in a crisscross pattern.
[0034] When the branch rod 603 rotates along with the stirring rod 601, it stirs the material. Due to the rectangular shape of the branch rod 603, some of the material is moved to a higher position inside the rotating cylinder 201. Then, as the branch rod 603 rotates, the material falls from the higher position and is dried by the hot air blown out from the air outlet 8 on the side wall. The air outlet 8 is located on the side wall of the branch rod 603, which can prevent the material from blocking the air outlet 8 when the branch rod 603 is stirring. The hot air blown out from the air outlet 8 will also further blow away the material and prevent the air outlet 8 from being blocked.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
