Description

Technical Field

[0001] The invention belongs to the technical field of electrolytic silver powder preparation, and specifically relates to an electrolytic silver powder preparation device and a preparation process. Background Art

[0002] When an electrolyte is passed into the electrolytic cell, the electrolyte will continuously precipitate electrolytic silver powder on the outer surface of the cathode plate under the action of electrolysis after the current is passed, and the scraper will continuously scrape the two sides of the cathode plate to obtain the required electrolytic silver powder.

[0003] Chinese invention patent CN105040034B discloses a silver electrolytic cell, comprising: a cell body, wherein an electrolytic space is defined in the cell body, wherein a plurality of partitions are arranged in the electrolytic space along a first direction to divide the electrolytic space into a plurality of sub-cells interconnected at the bottom; a plurality of cathode plates are respectively arranged in the plurality of sub-cells; a stirring rod is respectively arranged in the plurality of sub-cells; a stirring drive assembly is arranged on the cell body and connected to the stirring rod to drive the stirring rod to reciprocate along the first direction; the electrolytic silver powder preparation device has low preparation efficiency and poor preparation effect.

[0004] Chinese invention patent CN106544700B discloses an electrolytic silver powder preparation system, including an electrolytic cell, a cathode and an anode, a cathode cooling system, a screw rod stirring and powder scraping device, a chain-type powder discharge mechanism, and a purification circulation system; the cathode cooling system includes a circulation pump, a circulation water inlet pipe, a circulation pipeline, a circulation water outlet pipe and a circulation heat dissipation tank; the screw rod stirring and powder scraping device includes a driving motor, a movable connecting rod, a support rod and a powder scraping plate; the electrolytic silver preparation device is difficult to operate and has a low electrolyte content.

[0005] If some electrolytic silver powder or impurities have different adhesion to the two sides of the cathode plate, the electrolytic silver powder or impurities cannot be completely and effectively scraped off by just the reciprocating left and right movement of the scraper, which will not only affect the normal electrolytic scraping of the electrolytic silver powder, but also hinder the reciprocating left and right movement of the scraper, thereby causing damage to the scraper.

[0006] In addition, the electrolyte inside the electrolytic cell will produce impurities during the electrolysis process. If the impurities cannot be discharged and cleaned in time, they will easily accumulate on the electrolyte and affect the normal electrolysis of the electrolytic silver powder.

[0007] At the same time, when the electrolytic silver on both sides of the cathode plate is scraped off with the help of the filter holes and the elastic brush, a large amount of electrolytic silver powder is easily attached to the inside of the filter holes and the outer surface of the elastic brush, thereby reducing the subsequent scraping and cleaning effect of the cathode plate. If the electrolyte inside the electrolytic cell is in a precipitated state for a long time, the contact degree between the electrolyte and the anode plate and the cathode plate is reduced, which will cause poor electrolysis effect and electrolysis efficiency that does not meet the requirements.

[0023] S1. Electrolyte is introduced into the shell component, the electrolytic component electrolyzes the electrolyte to form electrolytic silver powder, and the driving component drives the scraping component to move back and forth left and right above the electrolytic component and scrape the electrolytic silver powder on the outer surface of the electrolytic component;

[0024] S2. When the pressure value detected by the pressure sensor decreases and is less than the preset pressure value, the current of the electromagnetic seat increases, the magnetic attraction force exerted by the electromagnetic seat on the ferromagnetic block increases and drives the ferromagnetic block and the matching block to move closer to the end of the moving frame, the matching block drives the elastic slider to undergo elastic deformation, and the ferromagnetic block drives the scraper to move closer to the end of the moving frame and increases the squeezing force on the cathode plate;

[0026] S4, when the scraper on the right side is separated from the cathode plate, the currents of the two electromagnetic seats on the right side are constantly changing in an alternating manner, the magnetic attraction between the electromagnetic seat and the ferromagnetic block changes and drives the matching block to move in an alternating manner, the matching block cooperates with the wedge block in a wedge shape and drives the scraper to move up and down in an alternating manner, and the elastic brush and the filter hole move in an alternating manner to clear the blockage;

[0027] S5. After the scraper moves to the right to the maximum distance, the electromagnetic seat is powered off, and the elastic force of the elastic sleeve drives the scraper to move away from the moving frame end to the maximum distance, and the scraper pushes the impurities above the electrolyte to move synchronously and discharge them.

[0028] By further limiting the preparation process, the preparation efficiency can be improved and the preparation quality can be guaranteed.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

The device is simple to operate, stable and efficient, and effectively realizes the electrolysis and scraping processes of the electrolytic silver powder to meet the actual preparation needs. It has strong controllability and good adaptability, and can realize the preparation of different electrolytic silver powders. The comprehensive preparation efficiency is high and the preparation effect is good.

[0031] 2. The present application sets up a scraper, an elastic brush, a cathode plate and other components that cooperate with each other. The device uses the scraper and the elastic brush to scrape and clean both sides of the cathode plate. It can also adaptively adjust the scraping force and scraping position according to the adsorption force between the electrolytic silver powder or impurities and the cathode plate, thereby improving the scraping effect and scraping efficiency of the cathode plate.

[0032] 3. The present application sets up the cooperation of components such as scrapers, electromagnetic seats and ferromagnetic blocks. After scraping is completed, the device uses the elastic force of the elastic brush itself and the up and down movement of the scrapers on the front and rear sides to effectively clean and deblock the filter holes and the elastic brush, thereby ensuring the unobstructedness of the filter holes and the cleanliness of the elastic brush, and effectively avoiding affecting the subsequent scraping and cleaning of the outer surface of the cathode plate.

[0033] 4. The present application sets up the cooperation of components such as a moving frame, a scraper and a side hole. When the scraper moves to the maximum distance with the moving frame, the two scrapers move away from the moving frame end to the maximum distance. The scraper pushes impurities above the electrolyte into the side hole for recycling, thereby improving the purity and cleanliness of the electrolyte, and further ensuring the precipitation efficiency and quality of the electrolytic silver powder in the electrolyte.

[0050] The driving component 2 includes a through hole 207, which is opened inside the housing 101. The interior of the through hole 207 is movably connected with a connecting rod 206. The connecting rod 206 swings inside the through hole 207 and realizes the reciprocating left and right swing of the scraping component 4.

The end of the connecting rod 206 away from the base 201 is hinged to the side wall of the movable frame 401. The reciprocating swing of the connecting rod 206 drives the movable frame 401 to move back and forth left and right above the electrolytic component 3 and scrape.

[0051] The electrolytic assembly 3 includes a plurality of fixed plates 301, each of which is provided with a power-carrying plate 310 above the fixed plates 301. The bottoms of both sides of the power-carrying plate 310 are in contact with the top of the housing 101. Direct current is passed into the power-carrying plate 310. A plurality of anode plates 311 and cathode plates 312 are evenly arranged between the plurality of power-carrying plates 310. The outer surface of the anode plate 311 is provided with coarse silver. When the current required for electrolysis is passed into the power-carrying plate 310, the outer surface of the cathode plate 312 is electrolyzed to form a large amount of required electrolytic silver powder.

[0052] A cross bar 302 is provided inside the fixed plate 301, and both ends of the cross bar 302 are plugged and fixed to the side walls of the shell 101. The cross bar 302 plays a role of fixing and supporting the fixed plate 301. A plurality of access tubes 303 are evenly provided on one side of the shell 101. The other end of the access tube 303 passes through the shell 101 and reaches the inside of the electrolytic cell 102. The access tube 303 is located below the fixed plate 301. A plurality of liquid inlet holes 304 are evenly opened inside the access tube 303. The other end of the liquid inlet hole 304 is connected to the inside of the electrolytic cell 102. The electrolyte is passed into the electrolytic cell 102 along the access tube 303 and the liquid inlet hole 304 for subsequent electrolysis process.

[0053] A cleaning inclined frame 305 is provided above the fixed plate 301. The cleaning inclined frame 305 is mainly used to recycle impurities formed above the electrolyte during the electrolysis process to prevent the impurities from affecting the normal electrolysis and scraping of the electrolytic silver powder. The top of the cleaning inclined frame 305 is fixedly connected to the bottom of the power-on plate 310, so the height of the cleaning inclined frame 305 is lower than the power-on plate 310 and supports the power-on plate 310. The cleaning inclined frame 305 is inclined, and the impurities inside the cleaning inclined frame 305 flow obliquely downward along the inclined direction. A plurality of side holes 306 are evenly provided on both sides of the cleaning inclined frame 305. The other end of the side hole 306 is connected to the inside of the electrolytic cell 102. The electrolytic cell 102 The internal impurities enter the cleaning inclined frame 305 along the side hole 306 for recycling. The side hole 306 and the scraper 406 are staggered, so when the scraper 406 moves back and forth, the impurities can be pushed to the end of the side hole 306 and discharged. An impurity frame 308 is provided on one side of the outer surface of the shell 101. The lower output end of the cleaning inclined frame 305 is connected to the impurity frame 308 through a square hole 307. One side of the impurity frame 308 is connected to an impurity outlet pipe 309. The impurities inside the cleaning inclined frame 305 enter the impurity frame 308 along the square hole 307 and are discharged through the impurity outlet pipe 309 along the end of the impurity frame 308, thereby improving the electrolysis efficiency and electrolysis effect of the electrolytic silver powder.

[0054] The scraping assembly 4 includes a moving frame 401, which moves back and forth left and right above the electrolytic assembly 3 and scrapes and cleans the electrolytic silver powder formed on the outer surface of the cathode plate 312. A plurality of electromagnetic seats 403 are evenly arranged on both sides of the moving frame 401. A wedge block 404 is arranged at the other end of the electromagnetic seat 403. A T-shaped slot 405 is opened at the other end of the wedge block 404. An elastic slider 410 is slidably connected inside the T-shaped slot 405. The elastic slider 410 can move back and forth inside the T-shaped slot 405, and the elastic slider 410 is elastic. With the elasticity of the elastic slider 410, the extrusion and scraping force of the scraper 406 on the electrolytic silver powder on the outer surface of the cathode plate 312 can be improved. The elastic slider A pressure sensor 411 is provided at the end of 410, and the pressure sensor 411 is used to detect the pressure value at the end of the elastic slider 410. When the pressure value detected by the pressure sensor 411 decreases, it means that the extrusion and scraping force of the scraper 406 on both sides of the cathode plate 312 is reduced. A matching block 409 is provided at the other end of the elastic slider 410, and a ferromagnetic block 407 is movably connected to the other end of the matching block 409. A scraper 406 is provided at the other end of the ferromagnetic block 407. Multiple scrapers 406 match the outer surface of the cathode plate 312. The ferromagnetic block 407 moves and drives the scraper 406 to move back and forth synchronously. The scraper 406 scrapes the electrolytic silver powder formed by electrolysis on both sides of the cathode plate 312.

[0055] A plurality of movable seats 402 are evenly arranged on the top of the housing 101, and the top of the movable seat 402 is slidably connected to the bottom of the movable frame 401, and the movable seat 402 is used to improve the stability of the reciprocating lateral movement of the movable frame 401. The magnetic properties of the end faces facing the electromagnetic seat 403 and the ferromagnetic block 407 are different. When the electromagnetic seat 403 is energized and the magnetic force increases, the ferromagnetic block 407 is driven to move toward the end of the electromagnetic seat 403 by the magnetic attraction of the electromagnetic seat 403 to the ferromagnetic block 407, and the wedge block 404 is wedge-shaped and slidably matched with the matching block 409. When the ferromagnetic block 407 moves toward the end of the electromagnetic seat 403, the ferromagnetic block 407 drives the matching block 409 to move synchronously, and the matching block 409 is wedge-shaped matched with the wedge block 404 and drives the matching block 409 to move downward.

[0056] The side wall of the movable frame 401 is evenly provided with a plurality of elastic sleeves 415, the other end of the elastic sleeve 415 is fixedly connected to the side wall of the scraper 406, and the elastic sleeve 415 is elastic. The setting of the elastic sleeve 415 further improves the elastic reset performance of the scraper 406. The elastic sleeve 415 is located on the outer surface of the wedge block 404 and the matching block 409, so the elastic sleeve 415 can also wrap and protect the wedge block 404 and the matching block 409 to prevent the electrolyte inside the electrolytic cell 102 from affecting the normal operation of the wedge block 404 and the matching block 409.

[0057] The end of the elastic slider 410 away from the moving frame 401 is provided with a ball joint 408, and the other end of the ball joint 408 is fixedly connected to the side wall of the ferromagnetic block 407. The ferromagnetic block 407 can move in any direction on one side of the elastic slider 410 with the help of the ball joint 408. A plurality of filter holes 412 are evenly arranged inside the scraper 406. The electrolyte inside the electrolytic cell 102 is filtered with the help of the filter holes 412. The electrolytic silver powder and the electrolyte can pass through the filter holes 412, while impurities cannot pass through the filter holes 412 and are subsequently pushed out for cleaning. The opposite ends of the scraper 406 A plurality of elastic brushes 413 are evenly arranged on the surface, and the elastic brushes 413 cooperate with the scraper 406 to scrape the electrolytic silver powder on both sides of the cathode plate 312. The filter hole 412 and the elastic brush 413 match each other, so the elastic brush 413 can be directly inserted into the filter hole 412 to clear the filter hole 412, thereby avoiding blockage of the filter hole 412 and reducing subsequent filtering and cleaning of impurities. A splicing plate 414 is provided between two adjacent scrapers 406 on the same side, and the splicing plate 414 connects the two scrapers 406 on the same side, so that they have synchronization when working with each other.

[0058] Since some electrolytic silver powder or impurities have different adhesion to the two sides of the cathode plate 312, if only the scraper 406 moves back and forth, the electrolytic silver powder or impurities cannot be completely and effectively scraped off, which not only affects the normal electrolytic scraping of the electrolytic silver powder, but also hinders the reciprocating left and right movement of the scraper 406, thereby damaging the scraper 406; and the electrolyte in the electrolytic cell 102 will produce impurities during the electrolysis process. If the impurities cannot be discharged from the side holes 306 in time, they will accumulate on the electrolyte and affect the Normal electrolysis of electrolytic silver powder; at the same time, when the electrolytic silver on both sides of the cathode plate 312 is scraped off with the help of the filter hole 412 and the elastic brush 413, a large amount of electrolytic silver powder is easily attached to the inside of the filter hole 412 and the outer surface of the elastic brush 413, thereby reducing the subsequent scraping and cleaning effect of the cathode plate 312. At the same time, if the electrolyte in the electrolytic cell 102 is in a precipitated state for a long time, the contact degree between the electrolyte and the anode plate 311 and the cathode plate 312 is reduced, resulting in poor electrolysis effect and electrolysis efficiency that does not meet the requirements.

[0059] Therefore, when the electrolytic silver powder preparation device is actually used, Figure 2 As shown, the front, back, left and right directions are determined, and the control component controls the electrolyte to enter the electrolytic cell 102 along the inlet pipe 303 and the liquid inlet hole 304 to wait for the subsequent electrolysis process. At the same time, current is passed into the energized plate 310, and the current of the anode plate 311 and the cathode plate 312 is used to make the electrolytic silver powder in the electrolyte precipitate and adhere to the two sides of the cathode plate 312. The control component controls the drive motor 202 to start and drive the eccentric seat 203 to rotate, the eccentric seat 203 rotates and drives the central shaft 204 to rotate eccentrically, the central shaft 204 drives the sleeve 205 to rotate, the sleeve 205 drives the moving frame 401 to move back and forth left and right through the connecting rod 206, the moving frame 401 synchronously drives multiple scrapers 406 on both sides to move back and forth left and right on both sides of the cathode plate 312, the scrapers 406 drive multiple elastic brushes 413 to move back and forth left and right, thereby realizing the scraping process of the electrolytic silver powder or impurities attached to the two sides of the cathode plate 312.

[0060] At the same time, when the scraper 406 drives the elastic brush 413 to apply extrusion force to both sides of the cathode plate 312 and perform scraping, the control component initially controls the electromagnetic seat 403 to be energized and magnetic, and the matching block 409 is not in contact with the wedge block 404. The scraper 406 is driven by the magnetic attraction of the electromagnetic seat 403 to the ferromagnetic block 407 to squeeze the elastic sleeve 415 to move close to the end of the moving frame 401. The scraper 406 squeezes the elastic brush 413 to bend and fit on both sides of the cathode plate 312 for normal scraping. The elastic brush 413 scrapes the electrolytic silver powder or impurities on both sides of the cathode plate 312 and drops them into the electrolytic cell 102. At this time, the scraper 406 is subjected to the reaction force of the cathode plate 312 and The elastic slider 410 is driven by the ferromagnetic block 407 and the matching block 409 to be in the initial position inside the T-slot 405, and the pressure value detected by the pressure sensor 411 reaches the set pressure preset value. When the electrolytic silver powder or impurities attached to the outer surface of the cathode plate 312 have too strong adhesion, the elastic brush 413 cannot scrape them off. Therefore, the electrolytic silver powder or impurities exert a reaction force on the elastic brush 413 and make the scraper 406 move away from the end of the moving frame 401. The scraper 406 drives the elastic slider 410 to move away from the end of the moving frame 401 through the ferromagnetic block 407 and the matching block 409, and the pressure value detected by the pressure sensor 411 decreases and is less than the set pressure preset value.

[0061] In order to improve the scraping effect of the elastic brush 413 on the electrolytic silver powder or impurities on both sides of the cathode plate 312, the control component controls the current of the electromagnetic seat 403 to increase, so that the magnetic attraction exerted by the electromagnetic seat 403 on the ferromagnetic block 407 increases and drives the ferromagnetic block 407 to move closer to the end of the moving frame 401. The ferromagnetic block 407 drives the elastic slider 410 to move closer to the end of the moving frame 401 in the T-slot 405 through the matching block 409. At this time, the matching block 409 and the wedge block 404 are in parallel. If no contact occurs, the elastic slider 410 squeezes the inner wall of the T-slot 405, the pressure value detected by the pressure sensor 411 increases to the preset pressure value, and the ferromagnetic block 407 synchronously drives the scraper 406 to move closer to the end of the movable frame 401, and the scraper 406 drives the elastic brush 413 to move and increase the pressure value on the side wall of the cathode plate 312, and cooperates with the reciprocating left and right movement of the scraper 406 to achieve the scraping and cleaning effect of the electrolytic silver powder or impurities attached to the side wall of the cathode plate 312.

[0062] When the scraper 406 moves back and forth left and right and reaches the position again, the pressure value detected by the pressure sensor 411 is still less than the preset pressure value, indicating that only by increasing the squeezing force of the scraper 406 and the elastic brush 413 on both sides of the cathode plate 312, it is not possible to scrape and clean the attached electrolytic silver powder or impurities. Then, the control component controls the current of the electromagnetic seat 403 to increase further, and the magnetic attraction of the electromagnetic seat 403 to the ferromagnetic block 407 is further increased. The ferromagnetic block 407 drives the matching block 409 to move further toward the end of the moving frame 401, and the elastic slider 410 is squeezed to the maximum. To a large extent, the matching block 409 cooperates with the wedge block 404 in a wedge shape and drives the matching block 409 to move downward, and the matching block 409 synchronously drives the scraper 406 to move downward through the ferromagnetic block 407, and the scraper 406 drives multiple elastic brushes 413 to move downward. Then, the elastic brush 413 further increases the squeezing force on the electrolytic silver powder or impurities on both sides of the cathode plate 312, and synchronously realizes the vertical scraping of the electrolytic silver powder or impurities on both sides of the cathode plate 312 by the elastic brush 413, thereby further improving the scraping and cleaning effect of the electrolytic silver powder or impurities, and having stronger adaptability and higher cleaning performance.

[0063] The electrolytic silver powder on both sides of the cathode plate 312 is scraped off by the elastic brush 413 and enters the electrolytic cell 102 along the filter hole 412. The impurities move horizontally left and right as the elastic brush 413 moves and separates from the cathode plate 312, thereby realizing the separation process of the electrolytic silver powder and impurities, avoiding the electrolytic silver powder from being adsorbed on the outer surface of the impurities and reducing the amount of electrolyte.

[0064] When the scraper 406 on the right side detaches from the cathode plate 312 and continues to move, the elastic brush 413 detaches from the squeeze contact with the cathode plate 312 and recovers to a straight state with the help of elastic force. Then, the elastic brushes 413 at the corresponding front and rear positions vibrate and collide with each other with the help of their own elastic reset performance, thereby effectively realizing the self-cleaning process, and can also vibrate and separate the electrolytic silver powder or impurities attached to the outer surface, thereby improving the recovery effect of the electrolytic silver powder. At the same time, it can also apply an elastic stirring force to the electrolyte inside the electrolytic cell 102, and cooperate with the scraper 406 to move back and forth left and right to improve the mixing and stirring effect of the electrolyte inside the electrolytic cell 102, thereby preventing the electrolyte inside the electrolytic cell 102 from being left standing for a long time and precipitation.

[0065] Afterwards, the control component controls the current of the electromagnetic base 403 at the corresponding positions at the front and rear to change continuously, that is, when the current of the electromagnetic base 403 at the front side increases, the current of the electromagnetic base 403 at the rear side decreases, the magnetic attraction exerted by the electromagnetic base 403 at the front side on the ferromagnetic block 407 increases and drives the scraper 406 at the front side to move closer to the end of the moving frame 401, and at the same time, when the ferromagnetic block 407 moves, it drives the matching block 409 to cooperate with the wedge block 404 in a wedge shape and move downward, the matching block 409 and the ferromagnetic block 407 drive the scraper 406 to move downward, and the scraper 406 drives the elastic brush 413 to move downward, then the front side Multiple groups of elastic brushes 413 are staggered with multiple elastic brushes 413 on the rear side, and the elastic brushes 413 correspond to the filter holes 412. The elastic brushes 413 are inserted into the filter holes 412 to clear and unblock the filter holes 412, and the inner wall of the filter holes 412 scrapes and cleans the electrolytic silver powder or impurities attached to the outer surface of the elastic brushes 413. At the same time, the control component continuously repeats the above process and controls the front electromagnetic seat 403 and the rear electromagnetic seat 403 to change alternately, thereby effectively improving the cleanliness and clearing properties of each structure, and improving the subsequent cleaning effect of the electrolytic silver powder or impurities on the outer surface of the cathode plate 312.

[0066] When the scraper 406 at the front end moves downward, the scraper 406 drives the scraper 406 on the left side to tilt downward synchronously through the splicing plate 414, so that the position and direction of the left scraper 406 in contact with the cathode plate 312 change, and the movable frame 401 continuously moves back and forth left and right to achieve uninterrupted changes in the squeezing force on the side wall of the cathode plate 312, further improving the scraper 406 on the left side. Cleaning effect of the electrolytic silver powder or impurities on the outer surface of the cathode plate 312, and at the same time, when the scraper 406 moves back and forth inside the electrolytic cell 102, it can also stir and mix the electrolyte inside the electrolytic cell 102 in the forward and backward directions, thereby improving the electrolysis efficiency of the electrolyte inside the electrolytic cell 102 and avoiding precipitation problems caused by long-term standing.

[0067] When the moving frame 401 drives the scraper 406 on the right side to reach the side wall of the energized plate 310, the control component controls the electromagnetic seats 403 on the front and rear sides of the right end to be powered off, and the magnetic attraction exerted by the electromagnetic seat 403 on the ferromagnetic block 407 disappears. Under the elastic force of the elastic sleeve 415, the scraper 406 is driven to move away from the end of the moving frame 401 to the maximum distance. The scraper 406 pushes the impurities above the electrolyte and moves to the side hole 306. The impurities enter the cleaning inclined frame 305 along the side hole 306, and finally reach the impurity outlet pipe 309 through the square hole 307 and the impurity frame 308 for discharge, thereby effectively improving the effect of pushing and discharging impurities above the electrolyte, and avoiding the impurities from remaining above the electrolyte for a long time and affecting the subsequent electrolysis effect of the electrolyte.

[0068] When the scraper 406 moves forward and backward, the electrolyte and the electrolytic silver powder inside flow through the filter hole 412, so the electrolyte and the electrolytic silver powder will not enter the cleaning inclined frame 305 along the side hole 306 and be recovered. At the same time, the scraper 406 on the right side can also synchronously drive the scraper 406 on the left side to separate from the cathode plate 312 when moving in the forward and backward directions, so that the electrolytic silver powder or impurities attached to the outer surface of the scraper 406 and the elastic brush 413 can enter the electrolyte in time and wait for subsequent discharge. After the impurities are cleaned, the control component controls the power-on current of the electromagnetic seat 403 to restore the initial value, and the ferromagnetic block 407 drives the scraper 406 to move to the initial value close to the end of the moving frame 401, and repeats the above process so that the moving frame 401 drives multiple scrapers 406 to move to the right, thereby scraping and cleaning the electrolytic silver powder or impurities on the outer surface of the cathode plate 312.

[0069] When the amount of electrolytic silver powder at the bottom of the electrolytic cell 102 reaches a preset value, the control component controls the solenoid valve to open, and the electrolytic silver powder and part of the electrolyte at the bottom of the electrolytic cell 102 are discharged along the discharge pipe 103, and part of the electrolyte flows back to the inlet pipe 303 through the reflux pipe 104 to re-perform the electrolysis process, and the electrolytic silver powder is discharged downward and recycled, thereby completing the preparation process of the electrolytic silver powder.

[0070] The device is simple to operate, stable and efficient, and can effectively realize the electrolysis and scraping process of electrolytic silver powder, meet the actual preparation needs, and has strong controllability and good adaptability, and can realize the preparation of different electrolytic silver powders, with high comprehensive preparation efficiency and good preparation effect; at the same time, when scraping and cleaning the two sides of the cathode plate 312 with the help of the scraper 406 and the elastic brush 413, the scraping force and the scraping position can be adaptively adjusted according to the adsorption force between the electrolytic silver powder or impurities and the cathode plate 312, thereby improving the scraping effect and scraping efficiency of the cathode plate 312; and after the scraping is completed, with the help of the elastic force of the elastic brush 413 itself and the scrapers 406 on the front and rear sides, the scraper 406 can be scraped and cleaned. 6 moves up and down, and can also effectively clean and clear the filter hole 412 and the elastic brush 413, ensuring the unblockability of the filter hole 412 and the cleanliness of the elastic brush 413, and effectively avoiding the impact on the subsequent scraping and cleaning of the outer surface of the cathode plate 312; and when the scraper 406 moves to the maximum distance with the moving frame 401, the two scrapers 406 move away from the end of the moving frame 401 to the maximum distance, and the scraper 406 pushes the impurities above the electrolyte to the inside of the side hole 306 for recycling, thereby improving the purity and cleanliness of the electrolyte, and further ensuring the precipitation efficiency and precipitation quality of the electrolytic silver powder in the electrolyte.

[0071] The preparation process of the electrolytic silver powder preparation device as described above comprises the following steps:

[0072] S1. Electrolyte is introduced into the shell component 1, and the electrolytic component 3 electrolyzes the electrolyte to form electrolytic silver powder. The driving component 2 drives the scraping component 4 to move back and forth above the electrolytic component 3 and scrape the electrolytic silver powder on the outer surface of the electrolytic component 3.

[0073] S2. When the pressure value detected by the pressure sensor 411 decreases and is less than the preset pressure value, the current of the electromagnetic base 403 increases, the magnetic attraction force exerted by the electromagnetic base 403 on the ferromagnetic block 407 increases and drives the ferromagnetic block 407 and the matching block 409 to move closer to the end of the movable frame 401, the matching block 409 drives the elastic slider 410 to undergo elastic deformation, and the ferromagnetic block 407 drives the scraper 406 to move closer to the end of the movable frame 401 and increases the squeezing force on the cathode plate 312.

[0074] S3. When the scraper 406 moves back and forth to the impurity position and the pressure value detected by the pressure sensor 411 is still less than the preset pressure value, the current of the electromagnetic base 403 keeps changing, the magnetic attraction applied by the electromagnetic base 403 to the ferromagnetic block 407 changes and drives the ferromagnetic block 407 and the matching block 409 to move back and forth, the matching block 409 cooperates with the wedge block 404 in a wedge shape and the scraper 406 moves up and down, and the scraper 406 scrapes the two sides of the cathode plate 312 up and down.

[0075] S4. After the scraper 406 on the right side is separated from the cathode plate 312, the currents of the two front and rear electromagnetic seats 403 on the right side are constantly changing in an alternating manner, the magnetic attraction between the electromagnetic seat 403 and the ferromagnetic block 407 changes and drives the matching block 409 to change its moving distance, the matching block 409 cooperates with the wedge block 404 in a wedge shape and drives the scraper 406 to move up and down in an alternating manner, and the elastic brush 413 and the filter hole 412 move in an alternating manner to clear the blockage.

[0076] S5. After the scraper 406 moves to the right to the maximum distance, the electromagnetic base 403 is powered off, and the elastic force of the elastic sleeve 415 drives the scraper 406 to move to the maximum distance away from the moving frame 401. The scraper 406 pushes the impurities above the electrolyte to move synchronously and discharge.

[0077] By further limiting the preparation process, the preparation efficiency and preparation quality of electrolytic silver powder can be effectively improved.
