Description

Technical Field

[0001] This utility model relates to the field of aluminum fluoride production technology, specifically to an aluminum fluoride reaction vessel with a stirring mechanism. Background Technology

[0002] Aluminum fluoride is an inorganic, colorless or white crystalline substance, insoluble in water, acids, and alkalis. It is very stable but hydrolyzes upon heating. It is mainly used in aluminum smelting. The production of aluminum fluoride requires a reaction vessel. The existing technology is authorized under publication number CN 221046060. U's patent discloses a reactor for producing aluminum fluoride, including a reactor body with a cover plate screwed onto it. A motor is fixedly connected to the cover plate, and the output end of the motor is rotatably connected to the cover plate. A square rod is fixedly connected to the output end of the motor. Multiple evenly distributed support rods are fixedly connected to the reactor body, and a discharge port is fixedly connected to the reactor body. A stirring mechanism and a cleaning mechanism are provided inside the reactor body. This invention utilizes the design of the motor, which drives the square rod to rotate, thereby driving the connecting sleeve and stirring rod to rotate and stir the material. During the stirring process, the electric push rod can drive the connecting ring to move vertically, thus achieving the effect of the stirring rod rotating and moving up and down inside the reactor body, which can improve the stirring range and mixing effect of the material. However, the stirring unit of this device only stirs the aluminum fluoride raw material in the reactor, resulting in the aluminum fluoride raw material in the device always being mixed in a vortex state. There is room for improvement in the stirring and mixing efficiency of the aluminum fluoride raw material. Therefore, we propose an aluminum fluoride reactor with a stirring mechanism. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an aluminum fluoride reactor with a stirring mechanism. The device uses the cooperation of various components to make the aluminum fluoride raw material in the device mix in four mixed states. Through the collision and fusion of the aluminum fluoride raw material in the four mixed states, the stirring and mixing speed of the aluminum fluoride raw material in the device is improved, thereby indirectly improving the preparation speed of aluminum fluoride in the device. This can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an aluminum fluoride reaction vessel with a stirring mechanism, comprising a reaction shell, wherein a protective shell is provided on the upper side of the reaction shell, and a stirring mechanism is also provided;

[0005] The stirring mechanism includes an inner shaft, an outer shaft, an inner stirring rod, an outer stirring rod, an annular seat, and a spiral stirring blade. The outer shaft is rotatably connected to the top wall of the reaction shell via a bearing. The inner shaft is rotatably connected to the inside of the outer shaft via a bearing. An outer stirring rod is located at the lower outer end of the inner shaft, and an inner stirring rod is located at the lower outer outer end of the outer shaft. An annular seat is located on the outer side of both the outer and inner shafts, and a spiral stirring blade is located on the outer side of each annular seat. Through the cooperation of these components, the aluminum fluoride raw material in the device is mixed in four mixed states. The collision and fusion of the aluminum fluoride raw material in the four mixed states increases the stirring and mixing speed of the aluminum fluoride raw material, thereby indirectly increasing the preparation speed of aluminum fluoride.

[0006] Furthermore, it also includes a microcontroller, which is located outside the reaction shell. The input terminal of the microcontroller is electrically connected to an external power supply, which facilitates the control of the electrical components inside the device.

[0007] Furthermore, the stirring mechanism also includes a transmission assembly, which includes an auxiliary shaft, a first bevel gear, and a second bevel gear. The first bevel gear is rotatably connected to the inner wall of the protective shell via the auxiliary shaft. The upper ends of both the outer and inner shafts are located inside the protective shell and are provided with the second bevel gear. The second bevel gear is meshed with the first bevel gear, so that the inner and outer shafts inside the aluminum fluoride reactor rotate in opposite directions.

[0008] Furthermore, the stirring mechanism also includes a servo motor, which is located on the upper side of the protective shell. The input end of the servo motor is electrically connected to the output end of the microcontroller, and the output shaft of the servo motor is fixedly connected to the upper end of the inner shaft, providing power for the device to mix and stir the aluminum fluoride raw materials in the reactor.

[0009] Furthermore, a feed pipe is provided through the top wall of the reaction shell, and a discharge valve is provided at the discharge port of the conical bottom wall of the reaction shell to control the material in and out.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This aluminum fluoride reactor with a stirring mechanism has the following advantages:

[0013] When using an aluminum fluoride reactor, the inner shaft, outer shaft, inner stirring rod, outer stirring rod, annular seat, spiral stirring blades, and transmission components work together to mix the aluminum fluoride raw material in four mixed states.

[0018] 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.

[0019] Please see Figure 1-3 This embodiment provides a technical solution: an aluminum fluoride reactor with a stirring mechanism, including a reaction shell 1, a protective shell 3 on the upper side of the reaction shell 1, and a microcontroller 2 located outside the reaction shell 1. The input terminal of the microcontroller 2 is electrically connected to an external power supply. A feed pipe 5 is provided through the top wall of the reaction shell 1, and a discharge valve 6 is provided at the discharge port of the conical bottom wall of the reaction shell 1. An observation window 7 is installed in a rectangular groove opened on the inner wall of the reaction shell 1. The inner wall of the reaction shell 1 is coated with a ceramic coating. When using the device to mix and stir the aluminum fluoride raw material, firstly... The aluminum fluoride reaction raw materials are transported to the inside of the device through the feed pipe 5 via an external conveying device. The reaction state of aluminum fluoride in the device can be observed through the observation window 7. After the aluminum fluoride reaction is completed, the discharge valve 6 is opened and the material is collected through the discharge port of the conical bottom wall of the reaction shell 1. The inner wall of the device is improved by ceramic coating to enhance its wear resistance (because the particles of the ceramic coating form a dense structure, the low surface energy and high hardness can effectively reduce the friction and wear between the particles, thereby achieving the effect of reducing wear). It also includes a stirring mechanism 4.

[0020] The stirring mechanism 4 includes an inner shaft 41, an outer shaft 42, an inner stirring rod 43, an outer stirring rod 44, an annular seat 45, and a spiral stirring blade 46. The outer shaft 42 is rotatably connected to the top wall of the reaction shell 1 via a bearing 1. The inner shaft 41 is rotatably connected to the inside of the outer shaft 42 via a bearing 2. The outer stirring rod 44 is located at the lower outer end of the inner shaft 41, and the inner stirring rod 43 is located at the lower outer outer end of the outer shaft 42. An annular seat 45 is located on the outer side of both the outer shaft 42 and the inner shaft 41, and a spiral stirring blade 46 is located on the outer side of each annular seat 45. The stirring mechanism 4 also includes a transmission assembly 47, which includes an auxiliary shaft 471, a first bevel gear 472, and a second bevel gear 473. The first bevel gear 472 is rotatably connected to the inner wall of the protective shell 3 via an auxiliary shaft 471. The upper ends of the outer shaft 42 and the inner shaft 41 are both located inside the protective shell 3 and are equipped with a second bevel gear 473. The second bevel gear 473 meshes with the first bevel gear 472. The stirring mechanism 4 also includes a servo motor 48, which is located on the upper side of the protective shell 3. The input end of the servo motor 48 is electrically connected to the output end of the microcontroller 2. The output shaft of the servo motor 48 is fixedly connected to the upper end of the inner shaft 41. The microcontroller 2 starts the servo motor 48, causing its output shaft to drive the inner shaft 41 to rotate in the opposite direction. The inner shaft 41 is connected to the first bevel gear 472 via two second bevel gears 473. The meshing connection between 72 (both bevel gear 2 473 and bevel gear 1 472 are located inside the protective shell 3, which seals and protects them from external dust and other environmental interference) causes the outer shaft 42 to rotate synchronously in the forward direction. The inner shaft 41 drives the corresponding spiral stirring blade 46 to rotate in the reverse direction, and the outer shaft 42 drives the corresponding spiral stirring blade 46 to rotate in the forward direction. Since the two spiral stirring blades 46 have the same spiral direction, the upper spiral stirring blade 46 rotates in the forward direction, thereby stirring and mixing the aluminum fluoride raw material in the upper part of the device, and the lower spiral stirring blade 46 rotates in the reverse direction. The reverse rotation of the inner shaft 41 stirs and mixes the aluminum fluoride raw material at the bottom of the device. At the same time, the outer shaft 42 drives the inner stirring rod 43 to rotate in the forward direction, thereby stirring and mixing the aluminum fluoride raw material in the center of the device. The inner shaft 41 drives the outer stirring rod 44 to rotate in the reverse direction, thereby stirring and mixing the aluminum fluoride raw material at the outer edge of the device. Through the cooperation of various components, the aluminum fluoride raw material in the device is mixed in four different states. The collision and fusion of the aluminum fluoride raw material in the four mixed states increases the stirring and mixing speed of the aluminum fluoride raw material, thereby indirectly increasing the preparation speed of aluminum fluoride.

[0021] The working principle of the aluminum fluoride reactor with stirring mechanism provided by this utility model is as follows: When the device is used to mix and stir the aluminum fluoride raw material, the aluminum fluoride reaction raw material is first transported into the device through the feed pipe 5 by the external feeding device. Then, the single-chip microcomputer 2 starts the servo motor 48, which drives the inner shaft 41 to rotate in the reverse direction. The inner shaft 41 is connected to the meshing of two bevel gears 473 and bevel gear 472 (both bevel gears 473 and 472 are located inside the protective shell 3, which seals and protects the bevel gear transmission parts from external dust and other environmental interference). This causes the outer shaft 42 to rotate synchronously in the forward direction. The inner shaft 41 drives the corresponding spiral stirring blade 46 to rotate in the reverse direction, and the outer shaft 42 drives the corresponding spiral stirring blade 46 to rotate in the forward direction. Since the two spiral stirring blades 46 have the same spiral direction, the aluminum fluoride raw material in the upper part of the device is stirred and mixed by the forward rotation of the upper spiral stirring blade 46, and the aluminum fluoride raw material in the lower part of the device is stirred and mixed by the lower spiral stirring blade 46. The reverse rotation of plate 46 stirs and mixes the aluminum fluoride raw material at the bottom of the device. At the same time, the outer shaft 42 drives the inner stirring rod 43 to rotate forward, thus stirring and mixing the aluminum fluoride raw material in the center of the device. The inner shaft 41 drives the outer stirring rod 44 to rotate in the reverse direction, thus stirring and mixing the aluminum fluoride raw material at the outer edge of the device. The device uses four vortex mixing and stirring states. The aluminum fluoride raw material in each vortex mixing and stirring unit collides and blends with each other, so that the aluminum fluoride raw material can reach a homogeneous state relatively quickly, thereby improving the preparation speed of aluminum fluoride. The reaction state of aluminum fluoride in the device can be observed through the observation window 7. After the aluminum fluoride reaction is completed, the discharge valve 6 is opened, and the material is collected through the discharge port of the conical bottom wall of the reaction shell 1. The inner wall of the device is coated with a ceramic coating to improve its wear resistance (because the particles of the ceramic coating form a dense structure, the low surface energy and high hardness can effectively reduce the friction and wear between the particles, thereby achieving the effect of reducing wear).

[0022] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be a COP8CBE9, the servo motor 48 can be a DT-D02, and the microcontroller 2 controls the servo motor 48 using methods commonly used in the prior art.

[0023] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
