Description

Technical Field

[0001] The present invention relates to the technical field of chemical electrolysis, and in particular to a control device for the electrolytic production of potassium aurocyanide. Background Art

[0002] Gold plating has a history of more than one hundred years. At present, the commonly used gold plating processes at home and abroad are mainly divided into two categories: cyanide gold plating process and cyanide-free gold plating process. Although the cyanide gold plating process is mature, the plating solution contains highly toxic cyanide, which seriously pollutes the environment. The cyanide-free gold plating process mainly includes sulfite gold plating, which plays a decisive role in the gold plating process and the quality of gold-plated parts, has a wide range of applications, and meets the requirements of environmental protection electroplating.

[0003] A patent with the publication number CN116288561A discloses a cyanide-free gold plating solution and a method for electroplating gold using the cyanide-free gold plating solution: the cyanide-free gold plating solution is composed of 25 g / L of gold salt, 150 g / L of conductive salt, 50 g / L of acid-base regulator, 20 ppm of auxiliary agent, 10 ppm of brightening agent and ultrapure water. At the same time, in the present invention, an Ni barrier layer is deposited on the surface of the brass foil substrate before electroplating, so that the gold plating layer has good durability and integrity. At the same time, nicotinic acid and triethylenediamine used in the cyanide-free gold plating solution provided by the present invention have strong electron-donating ability, can provide stronger electron adsorption ability for the surface of the brass foil, and strengthen the deposition of gold on the surface of the brass foil.

[0004] In the existing electrolysis process, after an oxidation reaction occurs on the surface of the electrolytic rod, an oxide layer or other impurities are usually formed. These impurities will accumulate layer by layer on the surface of the electrolytic rod. As the thickness increases, the power supply inside the electrolytic rod will be blocked when discharging, resulting in uneven discharge efficiency of the electrolytic rod, and further leading to incomplete electrolysis of the cyanide-free gold plating solution. Moreover, these substances need to be cleaned in time to ensure the electrolysis efficiency and electrode performance. Summary of the Invention

An acid solution water tank is fixedly connected to the outer surface of the swing support arm. A circulating water guide pipe extending to the inner side wall surface of the closed half sleeve is fixedly connected to the output end of the acid solution water tank. A dilute hydrochloric acid solution is filled on the inner side wall surface of the acid solution water tank.

[0007] In an embodiment of the present invention, a motor one is fixedly installed on the back surface of the electrolytic cell and at the middle position of the top. The output end of the motor one is fixedly connected to one side surface of the support sleeve.

[0008] In an embodiment of the present invention, the other side surface of the support sleeve is movably sleeved on the inner side wall surface of the support limiting arm, and a motor three is fixedly installed on the inner side wall surface of the support sleeve.

[0009] In an embodiment of the present invention, a limiting rod is fixedly connected to the inner side wall surface of the support sleeve and at the bottom edge position of the motor three. The outer surface of the swing support arm is threadedly movably sleeved on the outer surface of the output end of the motor three.

[0010] In an embodiment of the present invention, the outer surface of the swing support arm is movably sleeved on the outer surface of the limiting rod, and a sealing layer is fixedly connected to the outer surface of the closed half sleeve.

[0011] In an embodiment of the present invention, an air guide pipe is fixedly installed on the top surface of the closed cover, and a ventilation slot is opened at the middle position on the top surface of the closed cover.

[0012] In an embodiment of the present invention, a dryer is fixedly installed on the top surface of the air guide pipe, and a filter screen plate is fixedly connected to the inner side wall surface at one end of the air guide pipe.

[0013] In one embodiment of the present invention, a sealing gasket strip is fixedly connected to the top inner wall surface of the electrolytic cell, and the bottom surface of the closing cover is movably overlapped on the top surface of the sealing gasket strip.

[0014] In one embodiment of the present invention, L-shaped hollow sleeves are fixedly connected to the edge positions on both sides of the bottom of the electrolytic cell, and the positions of the L-shaped hollow sleeves are arranged at the edge positions on both sides of the electrolytic rod.

[0016] The above technical solution of the present invention has the following advantages compared with the prior art:

[0017] The present invention discloses a control device for the electrolytic production of potassium cyanogenide. After the two sets of closed half sleeves are closed, the arc-shaped support plate on the second output end of the motor is attached to the outer surface of the electrolytic rod. At this time, the acid water tank is used to infuse the inside of the circulating water pipe with a dilute hydrochloric acid solution, and the dilute hydrochloric acid solution gradually fills the inside of the closed half sleeve. Then, the oxide layer on the outer surface of the electrolytic rod is gradually diluted by soaking in the dilute hydrochloric acid solution. At this time, the two pairs of arc-shaped support plates of the motor are rotated with the electrolytic rod as the center point, and The diluted oxide layer on the surface of the electrolytic rod is scraped and cleaned by the scraper strip on the inner wall of the arc-shaped support plate, and the oxide layer is mixed into the inside of the dilute hydrochloric acid solution. Under the rotation of the second motor and the arc-shaped support plate, the fast-flowing water source will drain the oxide layer left on the surface of the electrolytic rod. At this time, the circulating water pipe is used to absorb the dilute hydrochloric acid solution through the acid water tank, so that the dilute hydrochloric acid solution slowly descends inside the closed half sleeve, and the flowing water source will not cause the oxide layer to be adsorbed on the surface of the electrolytic rod for the second time;

[0018] The invention discloses a control device for the electrolytic production of potassium cyanide. When the oxide layer of the electrolytic rod inside the closed half sleeve is cleaned, the motor three is rotated to make the swing support arm slide to one side on the surface of the motor three and the limit rod, so that the closed half sleeve is separated from the surface of the electrolytic rod, and the closed cover is lifted in cooperation with the hydraulic support rod. When the closed half sleeve is completely separated from the surface of the electrolytic rod, the motor pair of support sleeves is rotated again to make the swing support arm swing vertically toward the back of the electrolytic cell. At this time, the closed cover is lowered by the hydraulic support rod, so that the bottom surface of the closed cover overlaps the top surface of the sealing pad strip, and the sealing pad strip is used to increase the sealing effect between the closed cover and the electrolytic cell.

[0019] A potassium gold cyanide electrolytic production control device according to the present invention, after the potassium gold cyanide solution inside the electrolytic cell is in a sealed state, the potassium gold cyanide solution inside the electrolytic cell is electrolyzed by an electrolytic rod. During the electrolysis process, a water pump is used to blow the potassium gold cyanide solution inside the L-shaped hollow sleeve, so that the solution inside the L-shaped hollow sleeve impacts and mixes towards the middle position on the inner side of the electrolytic cell. When the solutions at both ends collide, under the drainage of the arc-shaped drainage strip, the collided solution will spread upward, and under the push of the subsequent solution, the solution will diffuse to both sides, thereby maintaining the uniformity of the ion concentration in the solution. And the mixed potassium gold cyanide solution is secondarily absorbed through the top inlet of the L-shaped hollow sleeve, and the solution circulates inside the electrolytic cell, achieving the effect of maintaining the uniformity of the ion concentration in the solution.

Detailed implementation mode

[0030] The present invention will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the specific embodiments cited do not limit the present invention.

[0031] Please refer to Figure 1 - Figure 8 The present invention provides a potassium gold cyanide electrolysis production control device, including an electrolytic cell 11 and hydraulic support rods 14 fixedly installed on both side surfaces of the electrolytic cell 11, a closing cover 12 fixedly installed on the output end of the hydraulic support rods 14, and the bottom surface of the closing cover 12 is movably lapped on the outer surface of the top of the electrolytic cell 11, a support and limit arm 13 fixedly installed on one side surface of the electrolytic cell 11 and located at the top edge position, and an electrolytic rod 121 fixedly installed on the bottom surface of the closing cover 12 and inside the electrolytic cell 11; a support housing 132 is arranged on the back surface of the electrolytic cell 11, a swing support arm 133 is movably sleeved on the inner side wall surface of the support housing 132, a plurality of closing half sleeves 134 movably sleeved on the outer surface of the electrolytic rod 121 are fixedly connected to the outer surface of the swing support arm 133; a motor 2 a1 is fixedly installed on the inner side wall surface of the bottom of the closing half sleeve 134, an arc-shaped support plate a2 movably attached to the inner side wall surface of the closing half sleeve 134 is fixedly connected to the output end of the motor 2 a1, a mud scraping strip a3 movably sleeved on the outer surface of the electrolytic rod 121 is fixedly connected to the inner side wall surface of the arc-shaped support plate a2, an acid solution water tank a4 is fixedly connected to the outer surface of the swing support arm 133, a circulating water pipe a5 extending to the inner side wall surface of the closing half sleeve 134 is fixedly connected to the output end of the acid solution water tank a4, and a dilute hydrochloric acid solution is filled on the inner side wall surface of the acid solution water tank a4;

[0032] When the two groups of closed half sleeves 134 are wrapped around the outer surface of the electrolytic rod 121, the sealing layer 135 is used to seal the joints of the two groups of closed half sleeves 134. When the two groups of closed half sleeves 134 are closed, the arc-shaped support plate a2 on the output end of the second motor a1 is attached to the outer surface of the electrolytic rod 121. At this time, the acid water tank a4 is used to infuse the inside of the circulating water pipe a5 with dilute hydrochloric acid solution, and the dilute hydrochloric acid solution gradually fills the inside of the closed half sleeves 134. Then, the oxide layer on the outer surface of the electrolytic rod 121 is gradually diluted by soaking in the dilute hydrochloric acid solution. At this time, the arc-shaped support plate a2 is used by the second motor a1 to seal the outer surface of the electrolytic rod 121. The electrolytic rod 121 is rotated with the electrolytic rod 121 as the center point, and the diluted oxide layer on the surface of the electrolytic rod 121 is scraped and cleaned by the scraper strip a3 on the inner wall of the arc support plate a2, and the oxide layer is mixed into the inside of the dilute hydrochloric acid solution. Under the rotation of the motor a1 and the arc support plate a2, the fast-flowing water source will drain the oxide layer remaining on the surface of the electrolytic rod 121. At this time, the circulating water pipe a5 is used to absorb the dilute hydrochloric acid solution through the acid water tank a4, so that the dilute hydrochloric acid solution slowly descends inside the closed half sleeve 134, and the flowing water source will not cause the oxide layer to be adsorbed on the surface of the electrolytic rod 121 for a second time.

[0033] Furthermore, if Figure 1 and Figure 8 As shown, a motor 131 is fixedly installed on the back of the electrolytic cell 11 and at the middle position of the top, the output end of the motor 131 is fixedly connected to the surface of one side of the support casing 132, the other side surface of the support casing 132 is movably sleeved on the inner wall of the support limit arm 13, a motor 3 136 is fixedly installed on the inner wall of the support casing 132, a limit rod 137 is fixedly connected to the inner wall of the support casing 132 and at the bottom edge of the motor 3 136, and the outer surface of the swing support arm 133 is threaded and movably sleeved on the inner wall of the support casing 132. The outer surface of the swing support arm 133 is movably sleeved on the outer surface of the limit rod 137, and the outer surface of the closed half sleeve 134 is fixedly connected with a sealing layer 135. An air duct 122 is fixedly installed on the top surface of the closing cover 12, and a ventilation slot is provided on the top surface of the closing cover 12 and in the middle. A dryer 123 is fixedly installed on the top surface of the air duct 122, and a filter screen plate 124 is fixedly connected to the inner wall surface of one end of the air duct 122.

[0034] After the electrolytic rod 121 undergoes long-term electrolytic treatment inside the electrolytic cell 11, if an oxide layer forms on the surface of the electrolytic rod 121, the hydraulic support rod 14 is used to lift the closing cover 12. When the hydraulic support rod 14 is at its highest position, the motor 131 is used to swing the support sleeve 132, and the support limiting arm 13 is used to limit the swinging position of the support sleeve 132. When the support sleeve 132 rotates, the swinging support arm 133 on the inner side wall surface of the support sleeve 132 is lapped on the top surface of the electrolytic cell 11. At this time, the hydraulic support rod 14 is used to lower the closing cover 12, so that the swinging support arm 133 and the electrolytic rod 121 are in a vertically horizontal state, and the two sets of closing half sleeves 134 can completely wrap the electrolytic rod 121, which is convenient for later polishing the oxide layer on the surface of the electrolytic rod 121. Moreover, when the electrolytic rod 121 and the closing half sleeve 134 are in a mutually perpendicular state, when the closing half sleeve 134 polishes the electrolytic rod 121, it will not cause excessive impact between the surface of the electrolytic rod 121 and the closing half sleeve 134 due to the inclination of the electrolytic rod 121, resulting in damage to the surface of the electrolytic rod 121.

[0035] After the oxide layer on the electrolytic rod 121 inside the closing half sleeve 134 is cleaned, the motor 136 is used to rotate, causing the swinging support arm 133 to slide to one side on the surfaces of the motor 136 and the limit rod 137, so that the closing half sleeve 134 disengages from the surface of the electrolytic rod 121. The hydraulic support rod 14 is used to lift the closing cover 12. When the closing half sleeve 134 completely disengages from the surface of the electrolytic rod 121, the motor 131 is used to rotate the support sleeve 132, causing the swinging support arm 133 to swing vertically towards the back of the electrolytic cell 11. At this time, the hydraulic support rod 14 is used to lower the closing cover 12, so that the bottom surface of the closing cover 12 is lapped on the top surface of the sealing gasket 114, using the sealing gasket 114 to enhance the sealing effect between the closing cover 12 and the electrolytic cell 11.

[0036] Further, as Figure 1 - Figure 4 、 Figure 6 and Figure 8 shown, a sealing gasket 114 is fixedly connected to the inner side wall surface at the top of the electrolytic cell 11, and the bottom surface of the closing cover 12 is movably lapped on the top surface of the sealing gasket 114. L-shaped hollow sleeves 111 are fixedly connected to both side edge positions at the bottom of the electrolytic cell 11. The positions of the L-shaped hollow sleeves 111 are set at both side edge positions of the electrolytic rod 121. A water pump 112 is fixedly installed on the top surface of the L-shaped hollow sleeves 111. An arc-shaped drainage strip 113 is fixedly connected to the bottom surface of the electrolytic cell 11 and is located at the bottom edge position.

[0037] After the potassium chloroaurate solution inside the electrolytic cell 11 is in a sealed state, the potassium chloroaurate solution inside the electrolytic cell 11 is electrolyzed by the electrolytic rod 121. During the electrolysis process, the water pump 112 is used to blow the potassium chloroaurate solution inside the L-shaped hollow sleeve 111, so that the solution inside the L-shaped hollow sleeve 111 impacts and mixes towards the middle position on the inner side of the electrolytic cell 11. When the solutions at both ends collide with each other, under the drainage of the arc-shaped drainage strip 113, the collided solution will spread upward, and under the push of the subsequent solution, the solution will diffuse to both sides, thereby maintaining the uniformity of the ion concentration in the solution. The mixed potassium chloroaurate solution is secondarily absorbed through the top inlet of the L-shaped hollow sleeve 111, and the solution circulates inside the electrolytic cell 11 to maintain the effect of the uniformity of the ion concentration in the solution.

[0038] Working principle: After the electrolytic rod 121 has been electrolyzed inside the electrolytic cell 11 for a long time, if an oxide layer is generated on the surface of the electrolytic rod 121, the hydraulic support rod 14 is used to lift the sealing cover 12. When the hydraulic support rod 14 is at the highest position, the motor 131 is used to swing the support sleeve 132, and the support limiting arm 13 is used to limit the swing position of the support sleeve 132. After the support sleeve 132 rotates, the swing support arm 133 on the inner side wall surface of the support sleeve 132 is lapped on the top surface of the electrolytic cell 11. At this time, the hydraulic support rod 14 is used to lower the sealing cover 12, so that the swing support arm 133 and the electrolytic rod 121 are in a vertical and horizontal state, and the two closed half sleeves 134 can completely wrap the electrolytic rod 121, which is convenient for later polishing the oxide layer on the surface of the electrolytic rod 121. And when the electrolytic rod 121 and the closed half sleeve 134 are in a mutually perpendicular state, when the closed half sleeve 134 polishes the electrolytic rod 121, it will not cause excessive impact between the surface of the electrolytic rod 121 and the closed half sleeve 134 due to the inclination of the electrolytic rod 121, resulting in damage to the surface of the electrolytic rod 121.

[0039] When the two groups of closed half sleeves 134 are wrapped around the outer surface of the electrolytic rod 121, the sealing layer 135 is used to seal the joints of the two groups of closed half sleeves 134. When the two groups of closed half sleeves 134 are closed, the arc-shaped support plate a2 on the output end of the second motor a1 is attached to the outer surface of the electrolytic rod 121. At this time, the acid water tank a4 is used to infuse the inside of the circulating water pipe a5 with dilute hydrochloric acid solution, and the dilute hydrochloric acid solution gradually fills the inside of the closed half sleeves 134. Then, the oxide layer on the outer surface of the electrolytic rod 121 is gradually diluted by soaking in the dilute hydrochloric acid solution. At this time, the arc-shaped support plate a2 is used by the second motor a1 to seal the outer surface of the electrolytic rod 121. The electrolytic rod 121 is rotated with the electrolytic rod 121 as the center point, and the diluted oxide layer on the surface of the electrolytic rod 121 is scraped and cleaned by the scraper strip a3 on the inner wall of the arc-shaped support plate a2, and the oxide layer is mixed into the inside of the dilute hydrochloric acid solution. Under the rotation of the motor a1 and the arc-shaped support plate a2, the fast-flowing water source will drain the oxide layer left on the surface of the electrolytic rod 121. At this time, the circulating water pipe a5 is used to absorb the dilute hydrochloric acid solution through the acid water tank a4, so that the dilute hydrochloric acid solution slowly descends inside the closed half sleeve 134, and the flowing water source will not cause the oxide layer to be adsorbed on the surface of the electrolytic rod 121 for a second time;

[0040] After the oxide layer of the electrolytic rod 121 inside the closed half sleeve 134 is cleaned, the motor three 136 is rotated to make the swing support arm 133 slide to one side on the surface of the motor three 136 and the limit rod 137, so that the closed half sleeve 134 is separated from the surface of the electrolytic rod 121, and the closing cover 12 is lifted in cooperation with the hydraulic support rod 14. When the closed half sleeve 134 is completely separated from the surface of the electrolytic rod 121, the motor one 131 is used to rotate the support sleeve 132, so that the swing support arm 133 swings vertically toward the back of the electrolytic cell 11, and the closing cover 12 is lowered by the hydraulic support rod 14 at this time, so that the bottom surface of the closing cover 12 overlaps the top surface of the sealing gasket strip 114, and the sealing gasket strip 114 is used to increase the sealing effect between the closing cover 12 and the electrolytic cell 11;

[0041] After the potassium chloroaurate solution inside the electrolytic cell 11 is in a sealed state, the potassium chloroaurate solution inside the electrolytic cell 11 is electrolyzed by the electrolytic rod 121. During the electrolysis process, the water pump 112 is used to blow the potassium chloroaurate solution inside the L-shaped hollow sleeve 111, so that the solution inside the L-shaped hollow sleeve 111 impacts and mixes towards the middle position on the inner side of the electrolytic cell 11. When the solutions at both ends collide with each other, under the drainage of the arc-shaped drainage strip 113, the collided solution will spread upward, and under the push of the subsequent solution, the solution will diffuse to both sides, thereby maintaining the uniformity of the ion concentration in the solution. The mixed potassium chloroaurate solution is secondarily absorbed through the top inlet of the L-shaped hollow sleeve 111, and the solution circulates inside the electrolytic cell 11 to maintain the effect of the uniformity of the ion concentration in the solution.

[0042] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
