Description

Technical Field

[0001] This invention relates to the field of rare earth electrolysis control feeding technology, specifically a staged feeding control system for rare earth electrolysis. Background Technology

[0002] Currently, in the rare earth electrolysis process, feeding is generally carried out in two ways: manual feeding or continuous and uniform feeding by a feeding machine.

[0003] In the prior art, patent document CN113718298B discloses a staged control method and device for rare earth electrolysis feeding, including the following steps: S1. Dividing the rare earth electrolysis process into multiple stages; S2. Acquiring current and temperature data in the electrolytic cell, and determining the current stage of rare earth electrolysis based on the current and temperature data; S3. Calculating the feeding rate to be executed based on the current current, temperature and preset PID parameter information according to the current stage of rare earth electrolysis.

[0004] The aforementioned system achieves different feeding controls at different stages by combining the concept of phased control with PID automatic control. However, the existing technology lacks a dedicated device for implementing a phased feeding control system for rare earth electrolysis. Furthermore, existing control systems, while achieving phased feeding, are not convenient for maintaining and improving the high heat transfer surface area of ​​the electrode rods and the high electrolysis efficiency of the electrolysis system through the dynamic movement of the electrode rods. Based on this, the present invention provides a phased feeding control system for rare earth electrolysis to solve the problems mentioned in the background technology. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a staged feeding control system for rare earth electrolysis. This solves the problem that the prior art lacks a dedicated device for implementing a staged feeding control system for rare earth electrolysis, and that existing control systems, while achieving staged feeding, are not convenient for maintaining and improving the high heat transfer surface area of ​​the electrode rods and the high electrolysis efficiency of the electrolysis system through the dynamic movement of the electrode rods.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A staged feeding control system for rare earth electrolysis includes an electrolytic cell, a walkable frame installed on the electrolytic cell, two baffle plates installed on the walkable frame, both baffle plates slidingly attached to the electrolytic cell, a guide mechanism installed on the walkable frame, an electrolytic frame capable of reciprocating in the vertical direction drivenly connected to the guide mechanism, a reciprocating rocking module installed on the electrolytic frame, a rocking frame capable of reciprocating within ±30° drivenly connected to the reciprocating rocking module, and two symmetrically arranged electrolytic modules installed on the rocking frame;

[0007] The electrolysis module includes an electrode rod and a differential assembly. A rotary filter is rotatably mounted on the electrode rod. A set of stirring rods is installed at the bottom of the rotary filter. A spiral stirring blade is installed on the outer wall of the rotary filter. A spiral brush is rotatably connected to the inner wall of the rotary filter. The spiral brush is in contact with the electrode rod. Both the rotary filter and the electrode rod are driven by the differential assembly.

[0008] The electrolysis frame is equipped with a feeding module and an intelligent electronic control component. The intelligent electronic control component monitors the current and temperature parameters in the electrolysis cell in real time and realizes segmented feeding of the feeding module based on the current and temperature parameters.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the intelligent electronic control component includes a microcontroller installed on the end face of the electrolytic cell, a current monitoring sensor and a temperature probe installed on the electrolysis frame, and the data terminals of the current monitoring sensor and the temperature probe are both connected to the microcontroller.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, during use, the inside of the electrolytic cell is filled with electrolyte, the current detection sensor is used to monitor the current in the electrolytic cell in real time, and the temperature probe is used to monitor the temperature parameter of the electrolyte in real time.

[0012] Both the current monitoring sensor and the temperature probe feed the monitored data back to the microcontroller in real time. The microcontroller uses the data feedback from the current monitoring sensor and the temperature probe to realize intelligent segmented feeding of the feeding module.

[0013] Current monitoring sensors, temperature probes, and microcontrollers can all be customized or selected according to actual needs.

[0014] Furthermore, the guiding mechanism includes a motor mounted on the traveling frame, a positioning shaft mounted on the output shaft end of the motor, and a moving shaft rotatably connected to the electrolysis frame. The moving shaft has a hollow groove with an open top and a sliding connection to the positioning shaft. The cross-sections of the hollow groove and the positioning shaft are both regular polygons. Two gear shafts are rotatably connected to the traveling frame. The two gear shafts are linked by a first chain belt. One gear shaft and the positioning shaft are each equipped with a first bevel tooth, and the two first bevel teeth mesh with each other. A half-tooth gear is installed on the other gear shaft. A guiding gear plate is installed on the electrolysis frame. The half-tooth gear is drivenly connected to the guiding gear plate. A set of elastic reset members is installed between the electrolysis frame and the traveling frame.

[0015] The beneficial effect of adopting the above-mentioned further solution is that during electrolysis, the motor outputs a speed at a set power. After the motor outputs the speed, the electrolysis frame can reciprocate within a set stroke through the setting of the guide tooth plate, half tooth gear and elastic limit member. After the electrolysis frame reciprocates within the set stroke, it then drives the rocker and the two electrolysis modules to reciprocate within the set stroke.

[0016] Furthermore, the feeding module includes a storage hopper mounted on the walking frame and two feeding pipes mounted on the electrolysis frame. The bottom end of the storage hopper is connected to a three-way flexible hose. A discharge valve is fixedly installed at the connection between the storage hopper and the three-way flexible hose. The discharge valve is connected to a microcontroller. The other two ends of the three-way flexible hose are respectively connected to the two feeding pipes. The bottom surface of each of the two feeding pipes is connected to a set of vertically downward discharge nozzles. A conveying shaft is rotatably connected inside each of the two feeding pipes. A spiral conveying blade is installed on each of the two conveying shafts. The two spiral conveying blades are respectively in contact with the two feeding pipes. An outer vertical shaft and a horizontal shaft are rotatably connected to the electrolysis frame. The outer vertical shaft is driven by a second chain belt and is connected to a moving shaft. A second bevel tooth is installed on both the outer vertical shaft and the horizontal shaft. The two second bevel teeth mesh with each other. A third chain belt is driven by the horizontal shaft. Both of the two conveying shafts are driven by the third chain belt.

[0017] The beneficial effect of adopting the above-mentioned further scheme is that when rare earth oxide needs to be added to the electrolytic cell, the microcontroller controls the opening of the feeding valve. After the feeding valve is opened, the rare earth oxide stored in the storage hopper is evenly classified into two distribution pipes. After the motor is working, the two conveying shafts rotate. After the two conveying shafts rotate, under the action of the spiral conveying blades, the rare earth oxide entering the two distribution pipes is evenly injected into the electrolytic cell through multiple injection nozzles, thereby realizing distributed multi-point uniform injection when adding rare earth.

[0018] Specifically, during the phased feeding process, this device is equipped with four feeding stages: rapid heating stage, plate changing and electrolyte replenishment stage, constant temperature reaction stage, and furnace discharge stage. Each of the four stages corresponds to a current parameter range and a temperature parameter range. Each stage also corresponds to a feeding and discharging rate of a storage hopper, thereby achieving feeding rate control at different stages.

[0019] Furthermore, the reciprocating rocking module includes a rocking sleeve rotatably connected to the electrolysis frame. A torsion spring is fixedly installed at the rotatable connection between the rocking sleeve and the electrolysis frame. A rocking bevel tooth is installed on the rocking sleeve. A round shaft is rotatably connected to the inner wall of the electrolysis frame. The round shaft is connected to the outer vertical shaft via a fourth chain. Both the moving shaft and the round shaft are equipped with a notched bevel tooth. Two notched bevel teeth are respectively located on both sides of the rocking bevel tooth. Both notched bevel teeth have tooth surfaces. The tooth surfaces are evenly distributed with teeth that mesh with the rocking bevel tooth. The arc of the tooth surface is 30°. The tooth surfaces on the two notched bevel teeth are staggered by 180°.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, after the motor outputs a speed, through the setting of the torsion spring, the setting of the rocking bevel teeth, and the misalignment structure of the two missing bevel teeth and the tooth surfaces of the two missing bevel teeth, the rocker arm can reciprocate within ±30°.

[0021] By repeatedly shaking the cradle, the working position and angle of the two electrode rods in the electrolytic cell are changed. This repeated change in the working position and angle of the two electrode rods ensures that they act evenly on the electrolyte and the rare earth elements to be electrolyzed in the electrolytic cell. On the other hand, the shaking motion of the electrode rods also washes the surface of the electrode rods with electrolyte, thereby effectively reducing the residual rate and scaling rate of electrolyte material and electrolytic impurities on the electrode rods. Through the achievement of the above technical effects, the electrolytic surface area of ​​the electrode rods is effectively maintained, thus maintaining the high electrolysis efficiency of the two electrode rods.

[0022] Furthermore, the reciprocating rocking module also includes a spindle rotatably connected to the inner wall of the rocker sleeve. Both the spindle and the moving shaft are equipped with third bevel teeth, and the two third bevel teeth mesh with each other. A fourth chain belt is drivenly connected to the spindle.

[0023] Furthermore, the differential assembly includes a differential shaft rotatably connected to the cradle, the differential shaft being connected to a fourth chain belt drive, a differential bevel gear being installed on the differential shaft, and a fourth bevel gear being installed on both the rotary filter and the electrode rod, both of the fourth bevel gears meshing with the differential bevel gear, and the two fourth bevel gears being respectively disposed on both sides of the differential bevel gear.

[0024] The beneficial effect of adopting the above-mentioned further scheme is that, through the position setting of the differential shaft, differential bevel teeth and two fourth bevel teeth, the rotary filter and the electrode rod can rotate in opposite directions on the same axis.

[0025] By rotating the rotary filter, direct contact between the rare earth coarse material and the electrode rod is effectively avoided, thereby reducing the scaling rate on the surface of the electrode rod. The spiral stirring plate and spiral brush plate can achieve full mixing of the rare earth coarse material and the electrolyte on the one hand, and physical removal of impurities adhering to the electrode rod on the other hand, thereby maintaining a high electrolytic surface area of ​​the two electrode rods.

[0026] The rotary filter, spiral agitator, and spiral brush are all made of insulating plastic.

[0027] Furthermore, the rotary filter cylinder has multiple sets of regularly distributed filter holes, and the rocker arm is equipped with two conductive terminals, which are electrically connected to two electrode rods respectively.

[0028] The advantage of adopting the above-mentioned further solution is that the pore size of the filter can be customized according to actual needs, and the two electrode rods are the anode rod and the cathode rod, respectively.

[0029] Furthermore, the walking frame is equipped with two power walking mechanisms, both of which are adapted and connected to the electrolytic cell. The electrolytic cell is connected to a discharge pipe, and the two baffle plates are respectively arranged on both sides of the rotary filter cylinder.

[0030] The beneficial effects of adopting the above-mentioned further scheme are that, during electrolysis, two power walking mechanisms drive the walking frame to move back and forth in the electrolytic cell, thereby achieving uniform electrolysis of the electrolyte and the rare earth to be electrolyzed in the electrolytic cell. Through the setting of the unloading pipe, the electrolyzed material can be discharged quickly, and the electrolyte and electrolyzed substances can be processed subsequently. Through the setting of two baffle plates, the rare earth injection area can be restricted and the rare earth can be uniformly distributed in the electrolytic cell.

[0031] The beneficial effects of this invention are:

[0032] 1) When the present invention is working, on the one hand, it can realize the staged feeding control during rare earth electrolysis by monitoring the current parameters and temperature parameters of the electrolytic cell. On the other hand, the rare earth electrolysis system can maintain the high electrolytic surface area of ​​the electrode rod by the shaking motion of the electrode rod during rare earth electrolysis, thereby effectively maintaining the high electrolysis efficiency of the electrolysis system.

[0033] 2) In this invention, when rare earth oxides need to be added to the electrolytic cell, the microcontroller controls the opening of the feeding valve. After the feeding valve is opened, the rare earth oxides stored in the storage hopper are evenly distributed into the two feeding pipes. After the motor starts working, the two conveying shafts rotate. After the two conveying shafts rotate, under the action of the spiral conveying blades, the rare earth oxides entering the two feeding pipes are evenly injected into the electrolytic cell through multiple injection nozzles, thereby realizing distributed multi-point uniform feeding during rare earth addition. Specifically, when receiving material in stages, this device is set with four feeding stages: rapid heating stage, plate replacement and electrolyte replenishment stage, constant temperature reaction stage, and furnace discharge stage. Each of the four stages corresponds to a current parameter range and a temperature parameter range. Each stage corresponds to a feeding and discharging rate of a storage hopper, thereby realizing the control of the feeding rate under different stages.

[0034] 3) In this invention, after the motor outputs a certain speed, the torsion spring, the rocking bevel gear, and the misaligned structure of the two missing bevel gears and the upper tooth surfaces of the two missing bevel gears enable the rocker arm to reciprocate within ±30°. Through the reciprocating rocking of the rocker arm, the working position and working angle of the two electrode rods in the electrolytic cell are repeatedly changed. By repeatedly changing the working position and working angle of the two electrode rods, on the one hand, the two electrode rods can act evenly on the electrolyte and the rare earth to be electrolyzed in the electrolytic cell. On the other hand, the rocking motion of the electrode rods can achieve the flushing of the electrode rod surface by the electrolyte, thereby effectively reducing the residual rate and scaling rate of the electrolyte material and electrolytic impurities on the electrode rods. Through the realization of the above technical effects, the electrolytic surface area of ​​the electrode rods can be effectively maintained, thereby maintaining the high electrolytic efficiency of the two electrode rods.

[0035] 4) The present invention effectively avoids direct contact between rare earth coarse material and electrode rod by rotating the rotary filter, thereby reducing the scaling rate on the surface of the electrode rod. By setting the spiral stirring plate and spiral brush plate, the rare earth coarse material and electrolyte can be fully mixed on the one hand, and the impurities adhering to the electrode rod can be physically brushed off on the other hand, thereby maintaining the high electrolytic surface area of ​​the two electrode rods.

[0047] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0048] The present invention provides the following preferred embodiments.

[0049] like Figure 1-9 As shown, a staged feeding control system for rare earth electrolysis includes an electrolytic cell 1, on which a walkable frame 2 is installed.

[0050] Two power walking mechanisms 32 are installed on the walking frame 2. Both power walking mechanisms 32 are adapted and connected to the electrolytic cell 1. A discharge pipe 33 is connected to the electrolytic cell 1.

[0051] Two baffle plates 3 are installed on the walking frame 2, and both baffle plates 3 are slidably attached to the electrolytic cell 1;

[0052] During electrolysis, two power walking mechanisms 32 drive the walking frame 2 to move back and forth in the electrolytic cell 1, thereby achieving uniform electrolysis of the electrolyte and rare earth to be electrolyzed in the electrolytic cell 1. Through the setting of the discharge pipe 33, the electrolyzed material can be discharged quickly, and the electrolyte and electrolyzed substances can be processed subsequently. Through the setting of two baffle plates 3, the rare earth injection area is restricted and the rare earth is uniformly distributed in the electrolytic cell 1.

[0053] The walking frame 2 is equipped with a guide mechanism, and the guide mechanism is connected to an electrolytic frame 4 that can reciprocate in the vertical direction;

[0054] The guiding mechanism includes a motor 14 mounted on the traveling frame 2, a positioning shaft 15 mounted on the output shaft end of the motor 14, and a moving shaft 16 rotatably connected to the electrolytic frame 4. The moving shaft 16 has a hollow groove with an open top and a sliding connection to the positioning shaft 15. The cross-sections of the hollow groove and the positioning shaft 15 are both regular polygons. Two gear shafts 17 are rotatably connected to the traveling frame 2. The two gear shafts 17 are linked by a first chain belt. One gear shaft 17 and the positioning shaft 15 are both equipped with first bevel teeth, and the two first bevel teeth mesh with each other. A half-tooth gear 18 is installed on the other gear shaft 17. A guiding tooth plate 19 is installed on the electrolytic frame 4. The half-tooth gear 18 is connected to the guiding tooth plate 19. A set of elastic reset members 20 is installed between the electrolytic frame 4 and the traveling frame 2.

[0055] During electrolysis, the motor 14 outputs a speed at a set power. After the motor 14 outputs the speed, the electrolysis frame 4 can reciprocate within a set stroke through the setting of the guide tooth plate 19, the half tooth gear 18 and the elastic limit member. After the electrolysis frame 4 reciprocates within the set stroke, it then drives the rocker frame 5 and the two electrolysis modules to reciprocate within the set stroke.

[0056] A reciprocating rocking module is installed on the electrolysis frame 4. A rocking frame 5 that can reciprocate within ±30° is connected to the reciprocating rocking module. Two symmetrically arranged electrolysis modules are installed on the rocking frame 5.

[0057] The electrolysis module includes an electrode rod 6 and a differential assembly. A rotary filter 7 is rotatably mounted on the electrode rod 6. The rotary filter 7 has multiple sets of regularly distributed filter holes 31.

[0058] The pore size of filter 31 can be customized according to actual needs;

[0059] Two conductive terminals 36 are installed on the cradle 5, and the two conductive terminals 36 are electrically connected to the two electrode rods 6 respectively.

[0060] The two electrode rods 6 are the anode rod and the cathode rod, respectively;

[0061] Two baffle plates 3 are respectively set on both sides of the rotary filter cylinder 7;

[0062] A set of stirring rods 8 are installed at the bottom of the rotary filter cylinder 7. A spiral stirring blade 9 is installed on the outer wall of the rotary filter cylinder 7. A spiral brush blade 10 is rotatably connected to the inner wall of the rotary filter cylinder 7. The spiral brush blade 10 is in contact with the electrode rod 6. Both the rotary filter cylinder 7 and the electrode rod 6 are driven by a differential assembly.

[0063] The reciprocating rocking module includes a rocking sleeve 27 rotatably connected to the electrolysis frame 4. A torsion spring 28 is fixedly installed at the rotatable connection between the rocking sleeve 27 and the electrolysis frame 4. A rocking bevel tooth 29 is installed on the rocking sleeve 27. A round shaft 30 is rotatably connected to the inner wall of the electrolysis frame 4. The round shaft 30 is connected to the outer vertical shaft 25 via a fourth chain. Both the moving shaft 16 and the round shaft 30 are equipped with a bevel tooth 37. The two bevel teeth 37 are respectively located on both sides of the rocking bevel tooth 29. Both bevel teeth 37 are provided with tooth surfaces. The tooth surfaces are evenly distributed with teeth that mesh with the rocking bevel tooth 29. The arc of the tooth surface is 30°. The tooth surfaces on the two bevel teeth 37 are staggered by 180°.

[0064] When the motor 14 outputs a speed, the rocker arm 5 can reciprocate within a range of ±30° by setting the torsion spring 28, setting the rocking bevel 29, and setting the misalignment structure of the two missing bevel teeth 37 and the tooth surfaces of the two missing bevel teeth 37.

[0065] By repeatedly shaking the rocker arm 5, the working position and angle of the two electrode rods 6 in the electrolytic cell 1 are changed. This repeated change in the working position and angle of the two electrode rods 6 ensures that the two electrode rods 6 act evenly on the electrolyte and the rare earth to be electrolyzed in the electrolytic cell 1. On the other hand, the shaking motion of the electrode rods 6 also washes the surface of the electrode rods 6 with electrolyte, thereby effectively reducing the residual rate and scaling rate of electrolyte material and electrolytic impurities on the electrode rods 6. Through the achievement of the above technical effects, the electrolytic surface area of ​​the electrode rods 6 is effectively maintained, thereby maintaining the high electrolysis efficiency of the two electrode rods 6.

[0066] The reciprocating rocking module also includes a spindle 34 rotatably connected to the inner wall of the rocker sleeve 27. Both the spindle 34 and the moving shaft 16 are equipped with third bevel teeth, and the two third bevel teeth mesh with each other.

Both fourth bevel teeth mesh with the differential bevel teeth. The two fourth bevel teeth are respectively located on both sides of the differential bevel teeth.

[0068] By setting the positions of the differential shaft 35, the differential bevel teeth, and the two fourth bevel teeth, the rotary filter 7 and the electrode rod 6 can rotate in opposite directions on the same axis.

[0069] By rotating the rotary filter 7, direct contact between the rare earth coarse material and the electrode rod 6 is effectively avoided, thereby reducing the scaling rate on the surface of the electrode rod 6. By setting the spiral stirring plate 9 and the spiral brush plate 10, on the one hand, the rare earth coarse material and the electrolyte can be fully mixed, and on the other hand, the impurities adhering to the electrode rod 6 can be physically brushed off, thereby maintaining the high electrolytic surface area of ​​the two electrode rods 6.

[0070] The rotary filter cartridge 7, the spiral stirring plate 9, and the spiral brush plate 10 are all made of insulating plastic.

[0071] The electrolysis frame 4 is equipped with a feeding module and an intelligent electronic control component. The intelligent electronic control component monitors the current and temperature parameters in the electrolysis cell 1 in real time and realizes segmented feeding of the feeding module based on the current and temperature parameters.

[0072] The intelligent electronic control component includes a microcontroller 11 installed on the end face of the electrolytic cell 1, a current monitoring sensor 12 and a temperature probe 13 installed on the electrolysis frame 4, and the data terminals of the current monitoring sensor 12 and the temperature probe 13 are both connected to the microcontroller 11.

[0073] The beneficial effect of adopting the above-mentioned further solution is that, during use, the inside of the electrolytic cell 1 is filled with electrolyte, the current detection sensor is used to monitor the current in the electrolytic cell 1 in real time, and the temperature probe 13 is used to monitor the temperature parameters of the electrolyte in real time.

[0074] Both the current monitoring sensor 12 and the temperature probe 13 feed back the monitored data to the microcontroller 11 in real time. The microcontroller 11 uses the data feedback from the current monitoring sensor 12 and the temperature probe 13 to realize intelligent segmented feeding of the feeding module.

[0075] The current monitoring sensor 12, temperature probe 13, and microcontroller 11 can all be customized or selected according to actual needs.

[0076] The feeding module includes a storage hopper 21 mounted on the walking frame 2 and two feeding pipes 22 mounted on the electrolysis frame 4. The bottom end of the storage hopper 21 is connected to a three-way flexible hose 23. A discharge valve is fixedly installed at the connection between the storage hopper 21 and the three-way flexible hose 23. The discharge valve is data-connected to the microcontroller 11. The other two ends of the three-way flexible hose 23 are respectively connected to the two feeding pipes 22. The bottom surface of each of the two feeding pipes 22 is connected to a set of vertically downward discharging nozzles. Both feeding pipes 22 contain... The conveyor shafts 24 are rotatably connected, and each of the two conveyor shafts 24 is equipped with a spiral conveyor blade. The two spiral conveyor blades are respectively attached to the two material distribution pipes 22. The electrolysis frame 4 is rotatably connected with an outer vertical shaft 25 and a horizontal shaft 26. The outer vertical shaft 25 is connected to the moving shaft 16 via a second chain belt. The outer vertical shaft 25 and the horizontal shaft 26 are both equipped with second bevel teeth, and the two second bevel teeth mesh with each other. The horizontal shaft 26 is connected to a third chain belt, and both conveyor shafts 24 are connected to the third chain belt.

[0077] When rare earth oxide needs to be added to the electrolytic cell 1, the microcontroller 11 controls the feeding valve to open. After the feeding valve is opened, the rare earth oxide stored in the storage hopper 21 is evenly divided into two distribution pipes 22. After the motor 14 is working, the two conveying shafts 24 rotate. After the two conveying shafts 24 rotate, under the action of the spiral conveying blades, the rare earth oxide entering the two distribution pipes 22 is evenly injected into the electrolytic cell 1 through multiple injection nozzles, thereby realizing distributed multi-point uniform injection when adding rare earth.

[0078] Specifically, during the phased feeding process, this device is equipped with four feeding stages: rapid heating stage, plate replacement and electrolyte replenishment stage, constant temperature reaction stage, and furnace discharge stage. Each of the four stages corresponds to a current parameter range and a temperature parameter range. Each stage also corresponds to a feeding and discharging rate of a storage hopper 21, thereby achieving feeding rate control at different stages.
