Description

[0002] The electrolytic cell for rare earth metal production is a key equipment used to extract high-purity rare earth metals from rare earth oxides through molten salt electrolysis. Its core principle is to use direct current to reduce rare earth oxides (such as lanthanum oxide, cerium oxide, etc.) to metals in high-temperature molten salt.

[0003] In the prior art, rare earth metal production electrolytic cells are typically used with the cathode in the molten salt and the anode inserted into the molten salt from the top during use, and rare earth metals are separated in conjunction with the rare earth filled inside. However, the solid precipitated rare earth metals are solidified on the cathode rod during precipitation. On the one hand, the adhesion affects the electrolysis effect of the cathode rod. On the other hand, it is difficult to separate the solid rare earth metal from the cathode rod, and the operation is cumbersome. It requires shutdown for cleaning and processing, resulting in low overall electrolysis efficiency, great separation difficulty, and poor use effect. Summary of the Invention

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 9 As shown, an embodiment of the present invention provides an electrolytic cell for rare earth metal production, comprising a cell body 1 and an internal frame 2 fixed in the cell body 1, an anode mechanism 3 is provided on the top of the cell body 1 for lifting, side seats 4 are symmetrically provided on both sides of the cell body 1, a cathode mechanism 5 is provided on the inclined sleeve of the side seat 4, a collecting chamber 6 is provided at the bottom of the side seat 4, the cathode mechanism 5 comprises a cathode rod 51, a connecting rod 52 and an electrical connection line 53, the connecting rod 52 is fixed between the cathode rod 51 and the electrical connection line 53, a winding mechanism 7 is provided inside the side seat 4, one end of the electrical connection line 53 passes through the side seat 4 and is wound in the winding mechanism 7, a separation component 8 is provided inside the side seat 4, the cathode rod 51 tilts upward when the electrical connection line 53 is wound, and squeezes and scrapes off the solid rare earth metal on the surface with the separation component 8.

[0023] Example 1: When in use, rare earth oxides and materials are put into the internal frame 2, and the heating mechanism (not shown in the figure) inside the internal frame 2 is started to form a mixed solution. The electric push rod 32 in the anode mechanism 3 is started to control the anode plate 31 to move downward and insert it into the molten material. At the same time, the anode mechanism 3 and the cathode mechanism 5 are energized to perform electrolysis. The rare earth metals in the rare earth oxide are gathered and precipitated along the outer side of the cathode rod to form a solid. The winding mechanism 7 in a set of side seats 4 is started. The winding mechanism 7 winds up the electrical connection line 53 in the cathode mechanism 5, and the cathode rod 51 and the counterweight sealing block 54 are pulled upward along the separation oblique cavity 42 by the connecting rod 52. As the connecting rod 52 slides along the inner wall of the separation oblique cavity 42, the cathode rod 51 and the counterweight sealing block 54 slide upward along the separation oblique cavity 42. Sliding and squeezing push the wedge block 82 to compress, and the cathode rod 51 is gradually inserted into the arcuate semi-ring 81 of the separation component 8. As the cathode rod 51 slides along the surrounding surface surrounded by the arcuate semi-ring 81 and the wedge block 82, the rare earth metal solid layer formed on the cathode rod 51 is scraped off and falls into the bottom collection chamber 6 along the inclined separation inclined cavity 42 to separate and collect the solid rare earth metal. Then the winding mechanism 7 rotates in the opposite direction, and the counterweight sealing block 54 drives the cathode rod 51 to tilt downward and reinsert it into the molten material to continue the electrolysis treatment, and the two groups of cathode mechanisms 5 are separated alternately. After the electrolysis is completed, as the two groups of cathode mechanisms 5 move up and separate synchronously, the complete separation of the rare earth metals is quickly completed.

[0024] First, by utilizing the cooperation of the winding mechanism 7 and the cathode mechanism 5, the cathode mechanism 5 is pulled to slide into the side seat 4 during electrolysis, and acts relative to the separation component 8 in the side seat 4, so as to realize the rapid separation of the metal solids accumulated on the surface of the cathode rod 51, and avoid excessive accumulation of metal on the surface of the cathode rod 51 and affecting subsequent accumulation. In addition, the actual cleaning process does not require shutdown, and the cathode mechanisms on both sides are processed alternately. After all the rare earth metals in the material system are electrolytically separated, on the one hand, rapid separation is completed without stopping the machine, and on the other hand, the metal layer accumulated on the surface can be separated in time to avoid affecting the continuous separation effect, thereby comprehensively improving the electrolytic separation effect.

[0025] In addition, by coordinating the collection chamber 6 with the separation inclined chamber 42, when intermittent separation is continued during electrolysis, rapid collection after separation can be achieved without adding a special collection and processing process. Separation and collection are completed simultaneously, further improving the efficiency of electrolytic cell processing and achieving good use effect.

[0026] Example 2: When the material is being melted and before power is applied for electrolysis, the two sets of winding mechanisms 7 are controlled to repeatedly pull the cathode rod 51 into the separation inclined cavity 42, and cooperate with the counterweight sealing block 54 to drag the cathode rod 51 downward to reset and reinsert it into the molten material. As the multiple sets of counterweight sealing blocks 54 on both sides are reciprocatedly inserted and removed in the molten material, the molten material is fully mixed.

[0027] First, by again utilizing the tilted cathode mechanism 5 and coordinating with the winding and unwinding of the winding mechanism 7, when the material begins to melt, the winding mechanism 7 is utilized in a non-powered state to realize the reciprocating insertion of the cathode mechanism 5, thereby relatively disturbing the mixed molten material and improving the mixing effect of the mixed material. By utilizing the impact treatment of the molten material, relative mixing is achieved without the need for special mixing equipment, and the molten material is fully mixed, thereby improving the melting efficiency.

[0028] Among them, the side seat 4 includes a seat body 41, a separation oblique cavity 42, an installation cavity 43 and an adaptation groove 44. The separation oblique cavity 42 is opened in the seat body 41, the installation cavity 43 is opened on the outside of the seat body 41, and the adaptation groove 44 is opened inside the seat body 41 and is connected with the separation oblique cavity 42.

[0029] The separation inclined chamber 42 provides a separation processing space, and the installation chamber 43 provides a winding space.

[0030] Among them, the separation component 8 includes an arc-shaped semi-ring 81, a wedge 82 and a spring 83. There are two arc-shaped semi-rings 81 and they are symmetrically fixed in the separation oblique cavity 42. The wedge 82 is located between the two arc-shaped semi-rings 81. One end of the spring 83 is fixed in the adapter groove 44, and the other end is fixedly connected to the wedge 82. Both side surfaces of the wedge 82 are provided with inclined surfaces.

[0031] The separation component 8 realizes the scraping and stripping of the outer metal layer of the cathode rod 51 under relative sliding to realize the separation process. The wedge block 82 cooperates with the adapter groove 44 and can be hidden in the adapter groove 44 when the spring 83 is compressed. The rectangular block at the upper end of the connecting rod 52 can push the wedge block 82 away when it slides along the separation oblique cavity 42. On the one hand, it ensures that the cathode mechanism 5 slides stably in the separation oblique cavity 42 through the rectangular block on the connecting rod 52. On the other hand, it ensures that when the cathode rod 51 slides to the separation component 8, the outer side surface is fully scraped and separated.

[0032] Among them, an adapting inclined hole 11 is opened on the outer side of the trough body 1, one end of the adapting inclined hole 11 is connected to the separation inclined cavity 42, and the other end of the adapting inclined hole 11 passes through the internal frame 2, and one end of the cathode rod 51 passes through the adapting inclined hole 11 and extends to the inside of the internal frame 2.

[0034] Among them, the cathode mechanism 5 also includes a counterweight sealing block 54, which is fixed at the bottom of the cathode rod 51. The size of the counterweight sealing block 54 is adapted to the inner diameter of the separation oblique chamber 42. One end of the connecting rod 52 is a rectangular block, and both ends of the rectangular block are in contact with the inner wall of the separation oblique chamber 42. When the rectangular block slides and contacts the wedge block 82, the wedge block 82 is squeezed and hidden in the adaptation groove 44.

[0035] The cathode mechanism 5 can achieve stable resetting after unwinding through the counterweight sealing block 54 and can disturb the mixed material under impact, so that the melting material is fully mixed and the melting speed is accelerated.

[0036] Among them, a notch 9 is provided at the bottom of the counterweight sealing block 54, and a sealing strip 10 is provided inside the side seat 4. The sealing strip 10 is fixed in the separation inclined cavity 42, and one end of the sealing strip 10 is located in the adaptation inclined hole 11, and the sealing strip 10 is adapted to the notch 9.

[0037] By utilizing the corresponding arrangement of the sealing strip 10 and the notch 9, the bottom has a bypass capability when the cathode rod 51 drives the counterweight sealing block 54 to initially move, thereby preventing part of the molten liquid in the adapting inclined hole 11 from being compressed into the separation area during the upward movement, and sealing the bottom of the separation area after the notch 9 and the sealing strip 10 are sealed accordingly, ensuring that the molten liquid can fall into the collection chamber 6 for collection, and avoid sliding along the bottom into the internal frame 2.

[0038] The winding mechanism 7 includes a motor, a rotating shaft and a winding drum. The output shaft of the motor is fixedly connected to the rotating shaft. The winding drum is fixedly sleeved on the outside of the rotating shaft. The winding drum is located in the installation cavity 43.

[0039] Among them, a mixing component 12 is provided on the back of the trough body 1, and a rotating shaft of a winding mechanism 7 is connected to the mixing component 12 and controls the rotation of the mixing component 12. The mixing component 12 includes a flywheel 121, a rotating belt 122, a stirring plate 123 and a balance bar 124. The rotating belt 122 is transmission-connected to two sets of flywheels 121, the stirring plate 123 is fixedly connected to the outside of the rotating belt 122 and is located in the internal frame 2, the balance bar 124 is fixedly connected to the side of the stirring plate 123 and is slidably sleeved in the internal frame 2, one flywheel 121 is connected to the winding mechanism 7, and the front of the other flywheel 121 is rotatably mounted on the side seat 4 through a connecting shaft and a bearing to maintain the stability of the mixing component 12.

[0040] The stirring plate 123 stirs the molten liquid through the reciprocating rotation of the high-temperature resistant rotating belt 122. One end of the balance rod 124 is slidably sleeved on the inner wall of the internal frame 2 to maintain relative stability and ensure that the sliding is always stable. A sealing sleeve is provided on the outside of the trough body 1, and the sealing sleeve is sleeved on the outside of the rotating belt 122 to maintain dynamic sealing.

[0041] Among them, the anode mechanism 3 includes an anode plate 31, an electric push rod 32 and a sealing cover 33. The movable end of the electric push rod 32 is fixedly connected to the anode plate 31, the sealing cover 33 is fixed on the outside of the movable end of the electric push rod 32, and the electric push rod 32 is fixed above the tank body 1 through the top bracket.

[0042] The anode mechanism 3 can be raised and lowered in a controlled manner, and an air hole is provided on the top of the sealing cover 33. After sealing the upper space of the tank body 1, the gas in the anode area is guided to be discharged in a directional manner.

[0043] Example 3: During the electrolysis treatment, as the cathode rod 51 is subjected to separation treatment after tilting and stretching, the winding mechanism 7 synchronously controls the rotation of a flywheel 121 in the mixing component 12 during the repeated action. As one flywheel 121 drives the other flywheel 121 to rotate through the high-temperature resistant rotating belt 122, the stirring plate 123 on the rotating belt 122 moves back and forth horizontally in the molten liquid. The stirring plate 123 is used to continuously stir the molten material during the electrolysis to achieve timely mixing.

[0044] First, by reusing the winding action of the winding mechanism 7, during the electrolysis period, as the winding mechanism 7 is intermittently started to intermittently reel and unreel the cathode mechanism 5, the separation of the metal accumulated on the outer side of the cathode rod 51 is completed. At the same time, the winding mechanism 7 synchronously controls the action of the mixing component 12, so that when the high-temperature resistant rotating belt 122 rotates back and forth, it drives the connected stirring plate 123 to synchronously stir the molten liquid, thereby achieving enhanced mixing after melting, providing electrolysis uniformity, and further improving the electrolysis efficiency.

[0045] The working principle and use process of the present invention are as follows: when in use, rare earth oxide and material are put into the internal frame 2, the heating mechanism (not shown in the figure) inside the internal frame 2 is started to form a mixed solution, the electric push rod 32 in the anode mechanism 3 is started, the anode plate 31 is controlled to move downward and inserted into the molten material, and the anode mechanism 3 and the cathode mechanism 5 are energized at the same time to perform electrolysis. The rare earth metal in the rare earth oxide is gathered and precipitated along the outer side of the cathode rod to form a solid material, and the winding mechanism 7 in a set of side seats 4 is started. The winding mechanism 7 winds up the electrical connection wire 5 in the cathode mechanism 5. 3. The cathode rod 51 and the counterweight sealing block 54 are pulled upward along the separation inclined cavity 42 by the connecting rod 52. As the connecting rod 52 slides along the inner wall of the separation inclined cavity 42, the wedge block 82 is squeezed and pushed to compress, and the cathode rod 51 is gradually inserted into the arcuate semi-ring 81 of the separation assembly 8. As the cathode rod 51 slides along the surrounding surface surrounded by the arcuate semi-ring 81 and the wedge block 82, the rare earth metal solid layer formed on the cathode rod 51 is scraped off and falls along the inclined separation inclined cavity 42 into the bottom collection cavity 6 to separate and collect the solid rare earth metal. Then the winding mechanism 7 is reversed. The counterweight sealing block 54 rotates in the direction of rotation, and drives the cathode rod 51 to move downward and be reinserted into the molten material to continue the electrolysis process, and the two sets of cathode mechanisms 5 are separated alternately. After the electrolysis is completed, the two sets of cathode mechanisms 5 are synchronously moved upward and separated, and the complete separation of rare earth metals is quickly completed; when the material is melted and before the power is turned on for electrolysis, the two sets of winding mechanisms 7 are controlled to repeatedly pull the cathode rod 51 into the separation inclined cavity 42, and cooperate with the counterweight sealing block 54 to drag the cathode rod 51 downward to reset and reinserted into the molten material, and with the multiple sets of counterweight sealing blocks on both sides, the cathode rod 51 is moved downward and reset and reinserted into the molten material. 54 is inserted and removed back and forth in the molten material to fully mix the molten material. During the electrolysis treatment, as the cathode rod 51 is separated after being tilted and stretched, the winding mechanism 7 synchronously controls the rotation of a flywheel 121 in the mixing component 12 during the repeated action. As one flywheel 121 drives the other flywheel 121 to rotate through the high-temperature resistant rotating belt 122, the stirring plate 123 on the rotating belt 122 moves back and forth horizontally in the molten liquid. The stirring plate 123 is used to continuously stir the molten material during the electrolysis to achieve timely mixing.
