Description

Technical Field

[0001] The invention relates to the technical field of metal electrolysis heating, and in particular to a metal smelting heating device. Background Art

[0002] Molten salt electrolysis has been widely used in large-scale industrial production of rare earth metals and their alloys, such as copper, aluminum, manganese, nickel and cobalt. In the molten salt electrolysis of metals, it is necessary to accurately control parameters such as the electrolysis voltage. The basic principle is that under the action of a DC electric field, rare earth cations move toward the cathode and obtain electrons thereon to be reduced to metals. The current electrolytic heating furnace is widely used due to its simple structure and low cost. However, the current metal smelting and heating device is not convenient for automatic adjustment and adaptation of the cathode, and the corrosion damage to the cathode is large. It is also not convenient for the staff to accurately adjust the electrolysis voltage and other parameters according to the amount of electrolytic melt. At the same time, the cathode will absorb electrons and ions from the anode area, which is more prone to corrosion and is not convenient for automatic corrosion compensation. Manual operation and replacement are cumbersome. Corrosion will change the properties of the cathode such as conductive resistance, affecting the accuracy of the control of the electrolysis power-on parameters. At the same time, the workers' operation of taking liquids is highly dangerous and prone to splashing. Manual scooping is not accurate enough during sampling, and a large amount of precipitated impurities are easily taken out. Summary of the invention

[0026] Embodiment 2, on the basis of embodiment 1, the magnetic driving member 6 comprises: a lower guiding magnet 601 and an upper guiding magnet 602, a circle of lower guiding magnets 601 is fixedly installed inside the rotary connecting ring 501, and the spacing of the circle of lower guiding magnets 601 is the same; a circle of upper guiding magnets 602 is fixedly installed inside the rotary connecting ring 501; the spacing of the circle of upper guiding magnets 602 is the same; a circle of lower guiding magnets 601 is located below a circle of upper guiding magnets 602; a circle of lower guiding magnets 601 and a circle of upper guiding magnets 602 are arranged in a staggered manner; the expansion control member 7 comprises: a liquid taking cylinder 701, a sampling hole 7011 and a rotary control magnet 702, and the liquid taking cylinder 701 is fixedly installed inside the rotary connecting ring 501; the spacing of the circle of upper guiding magnets 602 is the same; the circle of lower guiding magnets 601 is located below the circle of upper guiding magnets 602; the circle of lower guiding magnets 601 and the circle of upper guiding magnets 602 are staggered; the expansion control member 7 comprises: a liquid taking cylinder 701, a sampling hole 7011 and a rotary control magnet 702, The bottom of the cylinder 701 is an inclined structure; the bottom of the liquid collection cylinder 701 is used to insert four opposite contraction blocks 204; three circles of sampling holes 7011 are opened on the liquid collection cylinder 701; a through hole for discharging the melt is provided on the top of the liquid collection cylinder 701; a circle of rotation control magnets 702 are fixedly embedded at the bottom of the liquid collection cylinder 701; the circle of rotation control magnets 702 are used to magnetically attract a circle of lower guide magnets 601 and a circle of upper guide magnets 602; the expansion control member 7 also includes: a splash guard ring 703 and a handle 704, the splash guard ring 703 is fixedly sleeved on the liquid collection cylinder 701; the splash guard ring 703 is aligned with the three circles of sampling holes 7011; two handles are fixedly installed on the liquid collection cylinder 701 The handle 704 adopts a magnetic driving member 6, cooperates with the expansion control member 7, and utilizes the characteristics of magnetic attraction. When the expansion control member 7 is manually operated to insert into the electrolytic heating pool 101 for liquid collection, the rotary connecting ring 501 can be automatically controlled to rotate. The operation is simple and reasonable, and the corrosion resistance accuracy of the cathode ring 401 of this structure can be ensured. The expansion control member 7 utilizes its own cylindrical structure and can also be inserted vertically downward into the electrolytic heating pool 101 for liquid collection. The sampling hole 7011 is located above the bottom of the liquid collection cylinder 701, which can prevent a large amount of impurities from being taken out. Compared with the manual scooping method, this structure is safer, and the splash-proof baffle 703 can prevent manual handling. , molten liquid splashes out of the sampling hole 7011, and two-person operation is more labor-saving; when the liquid taking cylinder 701 moves downward, the one-circle rotating control magnet 702 will first magnetically attract the upper guide magnet 602. If there is a misalignment between the one-circle upper guide magnet 602 and the one-circle rotating control magnet 702, under the action of magnetic force, the one-circle rotating control magnet 702 can magnetically correct the one-circle upper guide magnet 602, and the rotating connecting ring 501 will rotate. Similarly, as the one-circle rotating control magnet 702 continues to move downward, it can magnetically attract the one-circle lower guide magnet 601 again, so that the rotating connecting ring 501 rotates, to control the limit column 502 to adjust the position of the supporting cathode circle 401.

[0027] The working principle of this embodiment is as follows: after the material is filled into the electrolytic heating cell 101, the electric heating wire 1011 is energized for heating, and the anode plate 103 is energized. At this time, the float 301 can float on the liquid surface, and is used to control the height of the cathode ring 401 through the stop column 302. Even if the cathode ring 401 is corroded and shortened, the cathode ring 401 will move downward under the action of gravity and always fit the stop column 302, so as to achieve the purpose of corrosion compensation. When the liquid level changes, the float 301 will also drive the cathode ring 401 to rise and fall to adapt to the liquid level, and The electrical elevation column 403 also moves with it. The staff can observe the elevation scale line of the electrical elevation column 403 to know the liquid level height and adjust the electrolysis voltage and other parameters. When the liquid extraction cylinder 701 is inserted downward to extract liquid, the opposite contraction block 204 of the inclined surface can be automatically squeezed outward to expand, and the tension spring 203 can be stretched to extract the melt through the liquid extraction cylinder 701. The outward expansion slider 201 is manually pulled outward to open the opposite contraction block 204 to fill the material, and the melt can leak into the sampling hole 7011 for sampling.

[0028] The two persons hold the handle 704 respectively, and drive the liquid taking cylinder 701 to press down and insert the four opposite contraction blocks 204. When the liquid taking cylinder 701 moves down, a circle of rotary control magnet 702 will first magnetically attract the upper guide magnet 602. If there is a misalignment between a circle of upper guide magnet 602 and a circle of rotary control magnet 702, under the action of magnetic force, a circle of rotary control magnet 702 can magnetically correct a circle of upper guide magnet 602. At this time, the rotary connecting ring 501 will rotate. Similarly, as a circle of rotary control magnet 702 continues to move downward, a circle of lower guide magnet 601 can be magnetically attracted again to make the rotary connecting ring 501 rotate. When the rotary connecting ring 501 rotates, the floating box 301 is driven by the limit column 502 to drive the stop column 302 to rotate. The supporting cathode ring 401 is vertically limited by the electrical elevation column 403 and will not rotate with it, so as to control the stop column 302 to adjust the supporting cathode ring 40 1, the electrical elevation column 403 used does not affect the normal rotation of the rotary connecting ring 501. After a circle of rotary control magnets 702 are lowered, the liquid taking cylinder 701 is quickly inserted into the melt and the liquid taking is completed, and it can be quickly lifted up manually. Based on the current mature high-temperature resistant magnet technology, the outside of the rotary control magnet 702 can be wrapped with a thermal insulation layer such as rock wool, and the temperature will be greatly reduced after the rotary control magnet 702 is lifted. The upper guide magnet 602 and the lower guide magnet 601 are located above the liquid surface, and their temperature is not enough to cause demagnetization of the existing high-temperature resistant magnets, and demagnetization and other problems will not occur. During the process, a circle of rotary control magnets 702 will magnetically attract a circle of upper guide magnets 602 and a circle of lower guide magnets 601 again to ensure that the rotary connecting ring 501 can be controlled to rotate; when the liquid taking cylinder 701 is pulled out, the top of the liquid taking cylinder 701 and the sampling hole 7011 are used to discharge the melt for cooling.
