Description

Technical Field

[0001] The present invention relates to the field of rare earth metal preparation equipment, and in particular to a device and method for preparing rare earth metals with high stability and high consistency. Background Art

[0002] Rare earth metals (alloys) are widely used due to their unique properties. Currently, the preparation of rare earth metals (alloys) mainly adopts the molten salt electrolysis method of rare earth oxides. Rare earth metal preparation is a high-energy-consuming technology and has high requirements for equipment materials. The electrolytic cell material must have good chemical stability to prevent chemical reactions with the electrolyte and rare earth metals during the electrolysis process and the introduction of impurities. For example, using high-quality graphite materials to make the electrolytic cell can effectively prevent impurities from dissolving into the electrolyte through the electrolytic cell wall. The cathode material must ensure the smooth deposition of rare earth metals and will not form alloys with rare earth metals or chemically react with them to contaminate the products. The anode material must be resistant to oxidation and corrosion. If a graphite anode is used, the gases generated by the anode during the electrolysis process will often diffuse back to the cathode area, affecting the purity of the rare earth metal and the preparation of rare earth metals. At the same time, when new electrolyte is added during the preparation process, the purity difference between the new electrolyte and the original electrolyte often leads to problems with the consistency and stability of the rare earth metals prepared before and after.

[0013] Preferably, a method for preparing a rare earth metal with high stability and high consistency comprises the following preparation steps: S1. Before preparation, people can use fixing rods to install the cathode plate and anode plate into the electrolytic chamber. The fixing rods can be supported by the cross frame. After ensuring that the composition and proportion of the electrolyte meet the process requirements, the electrolyte and rare earth raw materials are added to the electrolytic chamber. Then, the electrolytic cell is started through the control panel. Under the action of direct current, the rare earth ions will obtain electrons on the cathode plate and be reduced to metals. At the same time, chlorine or oxygen gas is generated on the cathode plate. People can prepare rare earth metals by regularly collecting the precipitated rare earth metals from the cathode. S2. During the preparation process, people can start the servo motor, which can drive the driving gear column to rotate. The rotation of the driving gear column can drive the toothed belt to rotate synchronously. The limiting groove and the limiting rail can be used to guide and limit the toothed belt. When the toothed belt rotates in a cycle, the electrolyte in the electrolysis chamber can be stirred by the various mounting rods installed on the toothed belt. At the same time, when the mounting rod moves, the gear will engage with the rack on the inner wall of the electrolysis chamber, so that the gear will drive the rotating sleeve to rotate synchronously. The multiple electric heating rods installed on the fixed plate at the bottom of the rotating sleeve can achieve auxiliary heating of the newly added electrolyte, thereby reducing the overall heat loss rate of the electrolyte, so that the electrolyte inside the electrolysis chamber can be stably maintained at a preset temperature; S3. The rotation of the electric heating rod group can stir the electrolyte injection point and its vicinity, so that the added electrolyte can be more quickly integrated with the original electrolyte in the electrolytic chamber, so that the electrolyte in the electrolytic chamber can be kept homogeneous, thereby being able to prepare more stable rare earth metals. At the same time, the homogeneous electrolyte can make the prepared electrolyte have higher consistency; S4. When the toothed belt rotates, the scraper foot at the bottom of the mounting rod can continuously clean the edge seam of the bottom of the electrolytic chamber, thereby preventing impurities precipitated during the preparation process from accumulating at the edge seam of the electrolytic chamber, which would make subsequent cleaning difficult. S5. During the preparation of rare earth metals, the grid provided on the outside of the anode plate can intercept the tiny bubbles generated during the preparation of the anode plate. At the same time, the pump body inside the fixed tube can simultaneously extract the bubbles and electrolyte into the fixed tube through the suction holes inside the grid. The gas and electrolyte can then be introduced into the drain tube through the connecting tube. The electrolyte will then be deposited in the lower part of the drain tube due to gravity and discharged back into the electrolysis chamber through the drain holes. The gas extracted in steps S6 and S5 will be distributed in the upper part of the drain pipe and discharged from the electrolytic cell through the exhaust pipe and introduced into the recovery device to separate and collect the gas generated during the preparation, thereby preventing the gas generated by the anode plate during the electrolysis process from back-diffusion to the cathode plate area and affecting the purity of the rare earth metal; S7. During the preparation process, the solvent and other required elements can be added to the connection liquid through the tank and the feeding tube, so as to maintain the stability and efficiency of the rare earth metal preparation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: During the preparation process of the present invention, people can start the servo motor, which can drive the driving gear column to rotate. The rotation of the driving gear column can drive the toothed belt to rotate synchronously. The limiting groove and the limiting rail can be used to guide and limit the toothed belt. When the toothed belt rotates in a cycle, the electrolyte in the electrolysis chamber can be stirred by the various mounting rods installed on the toothed belt. At the same time, when the mounting rod moves, the gear will engage with the rack on the inner wall of the electrolysis chamber, so that the gear will drive the rotating sleeve to rotate synchronously. The multiple electric heating rods installed on the fixed plate at the bottom of the rotating sleeve can achieve auxiliary heating of the newly added electrolyte, thereby reducing the overall heat loss rate of the electrolyte, so that the electrolyte inside the electrolysis chamber can be stably maintained at a preset temperature, which is conducive to the stable precipitation of rare earth metals.

[0015] The rotation of the electric heating rod group can stir the electrolyte injection point and its vicinity, so that the added electrolyte can be more quickly integrated with the original electrolyte inside the electrolytic chamber, so that the electrolyte inside the electrolytic chamber can remain homogeneous, thereby enabling the preparation of more stable rare earth metals. At the same time, the homogeneous electrolyte can make the prepared electrolyte have higher consistency, which is beneficial to the actual preparation work.

[0016] When the toothed belt rotates, the scraper foot at the bottom of the mounting rod can realize continuous cleaning of the bottom edge joint of the electrolytic chamber, thereby preventing impurities precipitated during the preparation process from accumulating at the edge joint of the electrolytic chamber, which would cause difficulty in subsequent cleaning. This is beneficial to the cleaning of the electrolytic cell after preparation, so that the impurities in the electrolytic chamber can be removed more thoroughly, and the influence of accumulated impurities can be avoided in the subsequent preparation process, thereby effectively maintaining the purity curve of the rare earth metal produced during multiple long-term preparations.

[0017] In the preparation of rare earth metals, the grid set on the outside of the anode plate can intercept the tiny bubbles precipitated during the preparation of the anode plate. At the same time, through the operation of the pump body inside the fixed tube, the bubbles and electrolyte can be simultaneously extracted into the fixed tube using the suction holes on the inside of the grid. Then, the gas and electrolyte can be introduced into the drain pipe through the connecting tube. The electrolyte will then be deposited in the lower part of the drain pipe due to gravity and discharged back into the electrolysis chamber through the drain holes. The extracted gas will be distributed in the upper part of the drain pipe and discharged from the electrolytic cell through the exhaust pipe and introduced into the recovery device, thereby realizing the separation and collection of the gas generated during the preparation, thereby avoiding the gas generated by the anode plate during the electrolysis process from diffusing back to the cathode plate area and affecting the purity of the rare earth metal, which is beneficial to improving the stability and consistency of the prepared rare earth metal and is beneficial to practical use.

At the same time, the operation of the pump body inside the fixed tube 119 can simultaneously extract the bubbles and the electrolyte into the fixed tube 119 through the suction holes inside the grid 121. The gas and electrolyte can then be introduced into the drain pipe 114 through the connecting pipe 120.

At the same time, chlorine or oxygen gas is generated on the cathode plate 115. People can prepare rare earth metals by regularly collecting the precipitated rare earth metals from the cathode. During the preparation process, people can start the servo motor 131, which can drive the drive gear The column 122 rotates, and the rotation of the driving tooth column 122 can drive the toothed belt 110 to rotate synchronously. The limiting groove 132 and the limiting rail 129 can guide and limit the toothed belt 110. When the toothed belt 110 rotates in a cycle, the electrolyte in the electrolysis chamber 102 can be stirred by the various mounting rods 128 installed on the toothed belt 110. At the same time, when the mounting rod 128 moves, the gear 125 will engage with the rack 108 on the inner wall of the electrolysis chamber 102, so that the gear 125 will drive the rotating sleeve 124 to rotate synchronously. The multiple electric heating rods 123 installed on the fixed disk 127 at the bottom of the rotating sleeve 124 can achieve auxiliary heating of the newly added electrolyte, thereby reducing the overall heat loss rate of the electrolyte. , so that the electrolyte inside the electrolysis chamber 102 can be stably maintained at a preset temperature, which is conducive to the stable precipitation of rare earth metals. At the same time, the rotation of the electric heating rod 123 group can stir the electrolyte injection point and its vicinity, so that the added electrolyte can be more quickly integrated with the original electrolyte inside the electrolysis chamber 102, so that the electrolyte inside the electrolysis chamber 102 can be kept homogeneous, thereby being able to prepare more stable rare earth metals. At the same time, the homogeneous electrolyte can make the prepared electrolyte have higher consistency, which is conducive to the actual preparation work. At the same time, when the toothed belt 110 rotates, the scraper foot 113 at the bottom of the mounting rod 128 can achieve continuous cleaning of the bottom edge seam of the electrolysis chamber 102, avoiding precipitation during the preparation process. Impurities accumulate at the edge joints of the electrolytic chamber 102, making subsequent cleaning difficult. This is beneficial to the cleaning of the electrolytic cell 1 after preparation, so that the impurities in the electrolytic chamber 102 can be removed more thoroughly, so that in the subsequent preparation process, the influence of accumulated impurities can be avoided, thereby effectively maintaining the purity curve of the rare earth metal produced during multiple long-term preparations, which is beneficial to actual use. In the preparation of rare earth metals, the grid 121 arranged on the outside of the anode plate 116 can intercept the tiny bubbles precipitated during the preparation of the anode plate 116. At the same time, through the operation of the pump body inside the fixed tube 119, the bubbles and the electrolyte can be synchronously extracted into the fixed tube 119 using the suction holes inside the grid 121.Afterwards, the gas and electrolyte can be introduced into the drain pipe 114 through the connecting pipe 120. The electrolyte will then be deposited in the lower part of the drain pipe 114 due to gravity and discharged back into the electrolysis chamber 102 through the drain hole 117. The extracted gas will be distributed in the upper part of the drain pipe 114 and discharged from the electrolytic cell 1 through the exhaust pipe 118 and introduced into the recovery device, thereby achieving the separation and collection of the gas generated during the preparation.

10. A method for preparing a rare earth metal with high stability and high consistency, applied to a device for preparing a rare earth metal with high stability and high consistency as claimed in any one of claims 1 to 9, characterized in that: The method comprises the following preparation steps: S1. Before preparation, people can install the cathode plate (115) and the anode plate (116) into the electrolytic chamber (102) through the fixing rod (112), and support the fixing rod (112) through the cross frame (111). After ensuring that the composition and proportion of the electrolyte meet the process requirements, the electrolyte and the rare earth raw material are added into the electrolytic chamber (102), and then the electrolytic cell (1) is started through the control panel (109). Under the action of direct current, the rare earth ions obtain electrons on the cathode plate (115) and are reduced to metals. At the same time, chlorine or oxygen gas is generated on the cathode plate (115). People can prepare the rare earth metal by regularly collecting the precipitated rare earth metal from the cathode; S2. During the preparation process, the servo motor (131) can be started, and the driving tooth column (122) can be driven to rotate by the servo motor (131). The rotation of the driving tooth column (122) can drive the toothed belt (110) to rotate synchronously. The toothed belt (110) can be guided and limited by the limiting groove (132) and the limiting rail (129). When the toothed belt (110) rotates in a circular motion, the electrolyte in the electrolytic chamber (102) can be adjusted by the respective mounting rods (128) mounted on the toothed belt (110). When the mounting rod (128) moves, the gear (125) meshes with the rack (108) on the inner wall of the electrolysis chamber (102), so that the gear (125) drives the rotating sleeve (124) to rotate synchronously, and the newly added electrolyte can be auxiliary heated by a plurality of electric heating rods (123) installed on the fixed plate (127) at the bottom of the rotating sleeve (124), thereby reducing the overall heat loss rate of the electrolyte, so that the electrolyte inside the electrolysis chamber (102) can be stably maintained at a preset temperature; S3. The electrolyte injection point and its vicinity can be stirred by rotating the electric heating rod (123) group, so that the added electrolyte can be more quickly integrated with the original electrolyte in the electrolytic chamber (102), so that the electrolyte in the electrolytic chamber (102) can be kept homogeneous, thereby preparing a more stable rare earth metal. At the same time, the homogeneous electrolyte can make the prepared electrolyte have higher consistency; S4. When the toothed belt (110) rotates, the scraper foot (113) at the bottom of the mounting rod (128) can continuously clean the edge seam at the bottom of the electrolysis chamber (102), thereby preventing impurities precipitated during the preparation process from accumulating at the edge seam at the inner side of the electrolysis chamber (102), which would make subsequent cleaning difficult. S5. In the preparation of rare earth metals, the grid (121) disposed outside the anode plate (116) can intercept fine bubbles generated during the preparation of the anode plate (116). At the same time, the pump body inside the fixed tube (119) can be operated to simultaneously extract the bubbles and the electrolyte into the fixed tube (119) through the suction holes inside the grid (121). Then, the gas and the electrolyte can be introduced into the drain pipe (114) through the connecting pipe (120). Then, the electrolyte is deposited in the lower part of the drain pipe (114) due to gravity and is discharged back into the electrolysis chamber (102) through the drain hole (117); The gas extracted in steps S6 and S5 is distributed in the upper part of the drain pipe (114), and is discharged from the electrolytic cell (1) through the exhaust pipe (118) and introduced into the recovery device to separate and collect the gas generated during the preparation, thereby preventing the gas generated by the anode plate (116) during the electrolysis process from back-diffusion to the cathode plate (115) area and affecting the purity of the rare earth metal; S7. During the preparation process, the auxiliary solvent and other required elements can be added to the connection liquid through the tank body (104) and the feeding pipe (105), so as to maintain the stability and efficiency of the rare earth metal preparation.
