Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic equipment, in particular to a rotating device of an electrolytic furnace. Background Art

[0002] Rare earth metals, also known as rare earth elements, are the general term for 17 elements in the IIIB group of the periodic table, including scandium, yttrium, and lanthanide. They are usually represented by R or RE. It took 178 years from the discovery of the first rare earth element yttrium in 1794 to the discovery of the natural rare earth element promethium in 1972. It took people 178 years to find all 17 rare earth elements in nature. The luster of rare earth metals is between that of silver and iron. Rare earth metals are very chemically active. Scandium is dispersed in the earth's crust and is a byproduct of the extraction of metals such as tungsten and tin.

[0003] The methods for preparing rare earths mainly include metal reduction method and molten salt electrolysis method. At present, general light rare earth metals are produced by molten salt electrolysis method. Electrolysis of rare earth oxide fluoride salt system is a major method for preparing rare earth metals. Rare earth metal electrolysis furnace is the main equipment to implement this method. Rare earth metal electrolysis furnace is a process in which an electric current electrolyte solution or a molten electrolyte (also known as an electrolyte) causes a redox reaction at the cathode and anode. The electrochemical cell can undergo an electrolysis process when a DC voltage is applied. Under normal circumstances, the cathode of the electrolysis furnace is generally large in size and heavy in weight, which is not very convenient to adjust. The distance between the cathode and the anode of the electrolysis furnace is not convenient to adjust. In addition, modern electrolysis furnaces generate more heat when working. The heat will be conducted through the metal parts on the furnace body, causing damage to parts that are not resistant to high temperatures. Utility Model Content

[0039] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0040] like Figure 1-6 As shown, the following embodiment discloses a rotating device for an electrolytic furnace.

[0041] A rotating device for an electrolytic furnace, comprising:

[0042] The turntable 100 is used to install the furnace body 200 and drive the furnace body 200 to rotate;

[0043] The rotating mechanism 300 is located below the turntable 100 and drives the turntable 100 to rotate;

[0044] The rotating mechanism 300 at least includes a rotating assembly and a rotating seat 310. The rotating assembly is rotatably disposed on the rotating seat 310, driven to rotate by the driving mechanism 400, and extends above the rotating seat 310 to connect with the turntable 100.

[0045] The rotating seat 310 is provided with a cooling structure for cooling the rotating component.

[0046] The above is the basic solution of this embodiment.

[0047] Reference Figure 1 to Figure 3 As shown, the rotating mechanism 300 includes a mounting frame 500, and the turntable 100 is arranged on the mounting frame 500. At the same time, the rotating seat 310 is fixed at the center of the mounting frame 500; the furnace body 200 is limitedly installed on the turntable 100, and the turntable 100 is located on the rotating seat 310 and is connected to the rotating component; the driving mechanism 400 drives the rotating component to rotate, driving the turntable 100 to rotate, so that the furnace body 200 also rotates at a high speed, and the metal element formed by electrolysis in the furnace body 200 is thrown out by centrifugal motion and evenly deposited in the collecting bowl.

[0048] When electrolysis is carried out in the furnace body 200, an extremely high temperature is required, and the heat generated by the high temperature will be conducted to the rotating component. Therefore, a cooling structure is provided on the rotating seat 310. When the rotating component rotates, the cooling structure does not move with the rotating component, but is always located on the rotating seat 310. Therefore, the cooling structure is ensured to be stable and can continuously cool the rotating component.

[0049] Compared with setting the cooling structure on the rotating component, the cooling structure in this embodiment is set on the rotating seat 310, which will not move with the rotation of the rotating component, thereby avoiding damage to the cooling structure during high-speed rotation of the rotating component and reducing the cooling effect.

[0050] In this embodiment, a rotating cavity 311 for installing a rotating component is provided on the rotating seat 310 , and the cooling structure is located outside the rotating cavity 311 .

[0051] Specific reference Figure 3 and Figure 4 As shown, the turntable 100 is installed on the upper part of the rotating component, and the furnace body 200 is located at the upper end of the rotating component. When heat conduction is performed, the heat is conducted from the upper end of the rotating component to the lower end, so that the entire rotating component has high heat. A rotating cavity 311 is set on the rotating seat 310 to minimize the contact between the rotating seat 310 and the rotating component, thereby reducing heat conduction and preventing the rotating seat 310 from becoming a heat transfer carrier.

[0052] In this embodiment, the specific configuration of the cooling structure is as follows: the cooling structure is a cooling channel 312 , and the cooling channel 312 is arranged in a ring shape around the rotating chamber 311 .

[0053] The cooling channel 312 surrounds the rotating cavity 311 , and the heat is conducted to the air in the rotating cavity 311 through the rotating assembly, so that the rotating seat 310 absorbs the heat in the air, and the cooling channel 312 surrounds the rotating cavity 311 , that is, the side wall of the rotating cavity 311 on the rotating seat 310 is cooled.

[0054] Preferably, in this embodiment, a cooling liquid is provided in the cooling channel 312 .

[0055] The cooling liquid in this embodiment can be liquid water or a coolant with good heat absorption effect.

[0056] In this embodiment, the specific implementation of the rotating component is as follows: the rotating component includes a rotating shaft 320 and a first bearing 330 connected between the rotating shaft 320 and the rotating seat 310; the cooling structure at least covers the outside of the first bearing 330.

[0057] The rotating shaft 320 is a long shaft, the lower end of which is connected to the driving mechanism 400, and the upper end of which passes through the rotating seat 310 and is connected to the turntable 100. The first bearing 330 is sleeved on the rotating shaft 320 and is located in the rotating cavity 311 of the rotating seat 310, so that the rotating shaft 320 can rotate relative to the rotating seat 310.

[0058] The cooling structure is located outside the bearing, and the axial width of the cooling channel 312 is not less than the thickness of the bearing, that is, the cooling channel 312 is mainly used to cool the first bearing 330;

[0059] The heat of the furnace body 200 is mainly conducted through the rotating shaft 320. When the heat is conducted to the lower end of the rotating shaft 320, since the rotating chamber 311 is a cavity, most of the heat is absorbed by the air, and the heat is not high when it is conducted to the rotating seat 310. In the part located at the first bearing 330, since the rotating shaft 320, the first bearing 330 and the rotating seat 310 are in contact in sequence, a large amount of heat will be quickly conducted to the rotating seat 310 through the first bearing 330, thereby causing the first bearing 330 and the rotating seat 310 to heat up quickly.

[0060] The cooling structure is disposed outside the first bearing 330 , and can quickly cool the rotating seat 310 and the first bearing 330 , thereby cooling the rotating shaft 320 .

[0061] Preferably, in this embodiment, the first bearing 330 is selected as a tapered roller bearing, and two of them are provided, which are respectively located at the upper and lower ends of the rotating cavity 311 on the rotating seat 310.

[0062] Tapered roller bearings are separable bearings, and both the inner and outer rings of the bearings have tapered raceways. This type of bearing is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to radial loads, an axial force component will be generated, so another bearing that can withstand the axial force in the opposite direction is needed to balance it.

[0063] Compared with conventional bearings, tapered rollers can withstand greater loads.

[0064] Meanwhile, in this embodiment, the upper and lower ends of the rotating chamber 311 are sealed by an oil seal 340 , and the first bearing 330 is located on the inner side of the oil seal 340 .

[0065] In order to ensure the stability of the furnace body 200 during high-speed rotation, in this embodiment, a supporting structure is provided between the turntable 100 and the mounting frame 500 , and the supporting structure is provided around the rotating assembly to support the turntable 100 .

[0066] A plurality of positioning shafts are provided on the turntable 100 to position the furnace body 200 and ensure the connection between the furnace body 200 and the turntable 100; at the same time, when the rotating shaft 320 rotates at high speed, it will produce extremely fast shaking. Although it is stabilized by the setting of bearings, there are still some small shakings that cannot be eliminated. When these small shakings are transmitted to the turntable 100, it will cause the turntable 100 to rotate unstably; therefore, in this embodiment, a supporting structure is provided to support the turntable 100 so that the turntable 100 remains stable during rotation.

[0067] The specific implementation of the support structure in this embodiment is as follows: the support structure includes a plurality of spherical support wheels 610 , and a track ring 620 capable of accommodating the upper ends of the spherical support wheels 610 is disposed at the bottom of the turntable 100 .

[0068] Reference Figure 5 and 6 As shown, the support wheel is vertically arranged, and the upper end is an arc-shaped surface, and the arc-shaped end is inserted into the track groove 621 of the track ring 620. When the turntable 100 rotates, the support wheel always rotates along the track ring 620, supporting the track ring 620 in the vertical direction, thereby supporting the turntable 100.

[0069] During the rotation process, the support wheel contacts and moves relative to the track ring 620. In order to reduce friction as much as possible, in this embodiment, the movement mode is set to rolling. The specific implementation method is as follows: the spherical support wheel 610 is axially provided with a rotating shaft, and the rotating shaft is movably mounted on the support seat 630 through a second bearing 640.

[0070] The support wheel is rotatably connected to the support seat 630 via a rotating shaft. When the turntable 100 drives the track ring 620 to rotate, the support wheel is driven to rotate, so that the support wheel rolls on the track ring 620, reducing friction.

[0071] In this embodiment, the driving mechanism 400 includes a driving component 710 and a transmission assembly. The transmission assembly includes a driving wheel 721 and a driven wheel 722 connected by a belt 723 . The rotating assembly is connected to the driven wheel 722 .

[0072] The rotating shaft 320 and the driven wheel 722 are coaxially arranged, and preferably, the lower end of the rotating shaft 320 is limitedly engaged with the driven wheel 722 .

[0073] The driving component 710 is a driving motor, and the driving wheel 721 is connected to the output shaft of the driving motor. The driving motor drives the driving wheel 721 to rotate, and the driven wheel 722 is also rotated through the belt 723, thereby driving the rotating shaft 320 on the driven wheel 722 to rotate.

[0074] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
