Description

Technical Field

[0001] The invention belongs to the technical field of zinc slag purification, and in particular relates to a device and a method for purifying zinc powder from zinc-containing slag. Background Art

[0002] Zinc slag is a solid by-product produced during zinc smelting or hot-dip galvanizing processes. It is mainly composed of waste slag, slag copper, slag, etc. in zinc ore. The composition of zinc slag may vary depending on the production process and raw materials. It may contain various metal elements such as zinc, iron, lead, tin, chromium, as well as chemical substances such as zinc chloride.

[0003] Zinc powder is a dark gray powdered metallic zinc that can be used as a pigment. It has strong covering power and has good anti-rust and atmospheric corrosion resistance. It is often used to make anti-rust paints, strong reducing agents, etc.

[0004] Purification devices are key equipment used to separate impurities from a mixture to improve the purity and quality of the mixture. These devices are widely used in many industries such as chemical, pharmaceutical, and food. In the process of extracting zinc powder from zinc slag, electrolysis is often used to purify zinc to produce high-purity zinc powder.

[0005] The authorization publication number "CN116445985B" records that "a process for preparing regenerated and energy-saving zinc powder with a high recovery rate of galvanizing tank slag is provided, which belongs to the technical field of regenerated zinc powder preparation equipment, and includes: adding raw materials, electrolysis, collecting chlorine, collecting zinc powder, removing waste and replacing metal rods, two transmission gears drive multiple driven gears to rotate by meshing with multiple driven gears, and the multiple driven gears drive the multiple prisms to rotate by sliding and engaging with multiple prisms, and the multiple prisms drive the multiple support blocks to rotate, and the multiple support blocks drive the multiple cathode metal plates to rotate in the multiple condensation barrels, and the multiple cathode metal plates rotate rapidly to throw the spongy zinc powder attached to the surface to the inner surface of the multiple condensation barrels for accumulation, and the spongy zinc powder on the surface of the multiple cathode metal plates is quickly desorbed, so as to improve the electrolytic production efficiency of the regenerated zinc powder."

[0006] In the above-mentioned patent, when multiple cathode metal plates are lifted into multiple condensate barrels, the rotating motor is started, and the output end of the rotating motor drives the driving gear to rotate, and the driving gear drives the two transmission gears to rotate by meshing with the two transmission gears, and the two transmission gears drive the multiple driven gears to rotate by meshing with the multiple driven gears, and the multiple driven gears drive the multiple prisms to rotate by sliding and engaging with the multiple prisms, and the multiple prisms drive the multiple support blocks to rotate, and the multiple support blocks drive the multiple cathode metal plates to rotate in the multiple condensate barrels, and the multiple cathode metal plates rotate by fast The spongy zinc powder attached to the surface is thrown off by the high-speed rotation to the inner surfaces of multiple condensation barrels for accumulation, and the spongy zinc powder on the surfaces of multiple cathode metal plates is quickly desorbed to improve the electrolytic production efficiency of regenerated zinc powder. However, in actual use, the spongy zinc powder will adhere to the surface of the cathode metal plate. The use of the rotating material throwing method will cause the spongy zinc powder attached to the surface of the cathode metal plate to not be completely removed, resulting in increased power consumption when the cathode metal plate that has not been completely desorbed is repeatedly electrolyzed zinc and the zinc powder desorption efficiency is seriously reduced after repeated zinc powder desorption.

[0023] A method for purifying zinc powder from zinc-containing slag comprises the following steps:

[0024] S1. Electrolysis:

[0025] The electronic valve on the discharge pipe is closed, and the ground zinc scum and electrolyte are added into the box through the feed pipe, and the liquid level of the electrolyte is not higher than the two rotating grooves. The motor is powered on to start, and the output end of the motor drives the driving gear to rotate. The driving gear drives the driven gear to rotate by meshing with the driven gear, and the driven gear drives the rotating frame to rotate slowly. At the same time, under the push of the first electric push rod, the pawl and the ratchet wheel limit the unidirectional rotation of the rotating frame through unidirectional engagement. The rotation of the rotating frame drives the multiple hollow columns to rotate, and the multiple hollow columns drive the multiple cathode sleeves to rotate unidirectionally in the box. The anode rod is energized into the electrolyte, and the ground zinc scum in the electrolyte adheres to the circumferential surface and bottom of the multiple cathode sleeves, so that the zinc scum in the box is electrolyzed;

[0026] S2. Efficient desorption:

[0027] A plurality of cathode sleeves are located at the bottom of a plurality of hollow columns, and the plurality of cathode sleeves rotate while electrolyzing. When a single cathode sleeve moves to the side end of the desorption bucket, the motor is powered off and stopped, and the rotation of the plurality of cathode sleeves is stopped. In the single cathode sleeve, the electromagnetic ring releases the magnetic attraction of the single cathode sleeve, and the reset spring pushes the single cathode sleeve to reset. The buffer pad buffers the lifted single cathode sleeve, and the single cathode sleeve is lifted once. Then, the motor is powered on to rotate the plurality of cathode sleeves, so that the lifted single cathode sleeve enters the desorption chamber from a rotating trough. In the bucket, when a single cathode sleeve moves to the bottom of the first infrared locator, the first infrared locator senses the obstruction of the rotating frame, and the first infrared locator triggers the power-off shutdown of the motor. At the same time, the first infrared locator triggers the output end of the third electric push rod to extend, and the output end of the first third electric push rod is inserted into a single hollow column to press down the single cathode sleeve, so that the single cathode sleeve is close to the desorption sleeve, and the single cathode sleeve is pressed down once. The electromagnetic ring in the single cathode sleeve magnetically fixes the top of the single cathode sleeve, and then the first third electric push rod The output end of the push rod is extended and retracted, and the nozzle draws the flushing liquid in the pressure pump to perform high-pressure flushing on the bottom of the single cathode sleeve, and the elemental zinc attached to the bottom of the single cathode sleeve is flushed into the desorption bucket, and then the second electric push rod is powered on to start the second electric push rod, and the output end of the second electric push rod is contracted to pull the second electric push rod, and the second electric push rod lifts the desorption sleeve, so that the desorption sleeve scrapes off the elemental zinc attached to the circumferential surface of the single cathode sleeve, and then the electromagnetic ring releases the magnetic fixation of the single cathode sleeve again, and the reset spring pushes the single cathode sleeve to be lifted for the second time, and the motor is powered on to start Push multiple cathode sleeves to rotate. When the second infrared positioner senses that the rotating frame moves to the lower side, it triggers the second and third electric push rods to be started. The second and third electric push rods are inserted into a single hollow column to press down a single cathode sleeve. In a single cathode sleeve, the electromagnetic ring and the cathode sleeve are magnetically fixed to achieve secondary downward pressure on the single cathode sleeve, making it convenient for the single cathode sleeve to be moved out of the desorption bucket from the rotating trough. By rotating multiple cathode sleeves, lifting and pressing twice, and high-pressure washing of the bottom of the nozzle and scraping of the desorption sleeve, efficient desorption of elemental zinc on the surface of multiple cathode sleeves is achieved.

[0028] S3, filter out chlorine:

[0029] During the efficient desorption process, the compression pump will extract the air in the box for filtration, and filter the waste gas generated by electrolysis in the box to avoid the overflow of waste gas and achieve the filtration of waste gas;

[0030] S4, discharge:

[0031] The desorbed zinc element falls into the desorption bucket, and during the high-pressure flushing of the nozzle, it is discharged along the desorption bucket and collected centrally, thus realizing the discharge of the zinc element.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In the present scheme, during the desorption process of elemental zinc attached to the surface of a single cathode sleeve, when the cathode sleeve is pressed down and close to the desorption sleeve, the electromagnetic ring in the single cathode sleeve magnetically fixes the top of the single cathode sleeve, and then the output end of the first third electric push rod is extended and retracted, and the nozzle draws the flushing liquid in the pressure pump to perform high-pressure flushing on the bottom of the single cathode sleeve, and the elemental zinc attached to the bottom of the single cathode sleeve is flushed into the desorption bucket, and then the second electric push rod is powered on and started, and the output end of the second electric push rod is contracted to pull the second electric push rod, and the second electric push rod is lifted up by the desorption sleeve, so that the desorption sleeve scrapes off the elemental zinc attached to the circumferential surface of the single cathode sleeve, and the elemental zinc falls into the desorption bucket for removal, thereby achieving efficient desorption of elemental zinc attached to the surface of the single cathode sleeve, avoiding incomplete desorption of sponge-like zinc powder, preventing the increase of power consumption when the cathode sleeve that has not been desorbed is repeatedly electrolyzed with zinc, and preventing the serious decrease in zinc powder desorption efficiency caused by repeated zinc powder desorption.

[0034] 2. In this scheme, when a single cathode sleeve fully attached with zinc element rotates into the desorption bucket, the motor is powered off and stopped, and the rotation of multiple cathode sleeves is stopped. In the single cathode sleeve, the electromagnetic ring releases the magnetic attraction of the single cathode sleeve, the reset spring pushes the single cathode sleeve to reset, and the buffer pad buffers the lifted single cathode sleeve, so that the single cathode sleeve is lifted once, and then the motor is powered on to rotate the multiple cathode sleeves, so that the lifted single cathode sleeve enters the desorption bucket from a rotating groove. When the single cathode sleeve moves to the bottom of the first infrared locator, the first infrared locator senses the obstruction of the rotating frame, and the first infrared locator triggers the power off and shutdown of the motor. At the same time, the first infrared locator triggers the output end of the third electric push rod to extend, and the output end of the first third electric push rod is inserted into a single hollow column to press down the single cathode sleeve, so that the single cathode sleeve is close to the desorption sleeve, so that the single cathode sleeve is pressed down once, and the electromagnetic ring in the single cathode sleeve magnetically fixes the top of the single cathode sleeve. When the single cathode sleeve after desorption needs to be When the cathode sleeve moves out of the desorption bucket, the electromagnetic ring releases the magnetic fixation of the single cathode sleeve again, and the reset spring pushes the single cathode sleeve to be lifted for the second time. The motor is powered on to drive the multiple cathode sleeves to rotate. When the second infrared locator senses that the rotating frame moves to the lower side, it triggers the start of the second and third electric push rods. The second and third electric push rods are inserted into a single hollow column to press down the single cathode sleeve. In the single cathode sleeve, the electromagnetic ring and the cathode sleeve are magnetically fixed to achieve secondary downward pressure on the single cathode sleeve, which is convenient for the single cathode sleeve. The single cathode sleeve is moved out of the rotating trough into the desorption bucket, and the single cathode sleeve fully attached with zinc is conveniently rotated into the desorption bucket and the single cathode sleeve after desorption is moved out of the desorption bucket by lifting and lowering the single cathode sleeve, so that the zinc dropped from the single cathode sleeve during desorption in the box body does not fall back into the box body again, thereby avoiding repeated electrolysis and desorption, reducing the power used for electrolysis and desorption, achieving the reduction of power usage of the zinc powder purification device in the zinc-containing slag, and then improving the power saving of the zinc powder purification device in the zinc-containing slag, and avoiding power waste.

[0035] 3. In this scheme, when it is necessary to rotate multiple cathode sleeves, the motor is powered on to start, the output end of the motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate by meshing with the driven gear, the rotating frame drives the multiple hollow columns to rotate, the multiple hollow columns drive the multiple cathode sleeves to rotate in the box, and the multiple cathode sleeves are rotated, so that the elemental zinc attached to the surface of the multiple cathode sleeves is generated at a time interval, and then the multiple cathode sleeves are ensured to be electrolyzed while rotating, and the elemental zinc can be electrolyzed and desorbed one by one, so that the zinc powder purification device in the zinc-containing slag can continuously electrolyze and desorb the elemental zinc, and improve the elemental zinc electrolysis and desorption efficiency of the zinc powder purification device in the zinc-containing slag, and at the same time, the rotation of the multiple cathode sleeves and the electrolyte generate a certain water flow disturbance, and the thickness of the elemental zinc attached to the multiple cathode sleeves is quantitatively controlled, which is convenient for the later desorption of elemental zinc, reduces the thrust requirement of the lifting frame, and reduces the maintenance difficulty of the zinc powder purification device in the zinc-containing slag.

[0036] 4. In this scheme, when the multiple cathode sleeves are rotated, the rotating frame synchronously drives the ratchet to rotate, and the first electric push rod pushes the pawl to engage with the ratchet in one direction. The ratchet limits the unidirectional rotation of the rotating frame by the unidirectional engagement with the pawl, thereby ensuring the unidirectional rotation of the multiple cathode sleeves, and does not cause repeated electrolysis and desorption of a single cathode sleeve, thereby avoiding unnecessary loss of production time and improving the purification efficiency of the zinc powder purification device in zinc-containing slag.

The buffer pad (8) buffers the lifted single cathode sleeve (10), thereby lifting the single cathode sleeve (10) once. Then, the motor (23) is powered on to start the rotation of the plurality of cathode sleeves (10), so that the lifted single cathode sleeve (10) rotates from one rotation. The groove (36) enters the desorption bucket (2). When the single cathode sleeve (10) moves to the bottom of the first infrared locator (45), the first infrared locator (45) senses the obstruction of the rotating frame (3). The first infrared locator (45) triggers the motor (23) to shut down. At the same time, the first infrared locator (45) triggers the output end of the third electric push rod (46) to extend. The output end of the first third electric push rod (46) is inserted into the single hollow column (9) to press down the single cathode sleeve (10), so that the single cathode sleeve (10) is close to the desorption sleeve (30). The single cathode sleeve (10) is pressed down once. The electromagnetic ring (11) in the single cathode sleeve (10) magnetically presses the top of the single cathode sleeve (10). The first third electric push rod (46) is fixed by suction, and then the output end of the first third electric push rod (46) is extended and retracted, and the nozzle (34) extracts the flushing liquid in the pressure pump (35) to perform high-pressure flushing on the bottom of the single cathode sleeve (10), and the single zinc attached to the bottom of the single cathode sleeve (10) is flushed into the desorption bucket (2), and then the second electric push rod (32) is powered on and started, and the output end of the second electric push rod (32) is contracted to pull the second electric push rod (32), and the second electric push rod (32) lifts the desorption sleeve (30), so that the desorption sleeve (30) scrapes off the single zinc attached to the circumferential surface of the single cathode sleeve (10), and then the electromagnetic ring (11) releases the magnetic fixation of the single cathode sleeve (10) again, and the reset spring (12) pushes the single cathode sleeve (10) to move upward. 0) is lifted for the second time, and the motor (23) is powered on to drive the multiple cathode sleeves (10) to rotate. When the second infrared positioner (45) senses that the rotating frame (3) moves to the lower side, the second third electric push rod (46) is triggered to start. The second third electric push rod (46) is inserted into the single hollow column (9) to press down the single cathode sleeve (10). In the single cathode sleeve (10), the electromagnetic ring (11) and the cathode sleeve (10) are magnetically fixed to achieve the secondary downward pressure of the single cathode sleeve (10), so that the single cathode sleeve (10) can be easily moved from the rotating groove (36) to the desorption bucket (2). By rotating the multiple cathode sleeves (10), lifting and pressing twice, and high-pressure washing of the bottom of the nozzle (34) and scraping of the desorption sleeve (30),Achieving efficient desorption of elemental zinc from the surfaces of multiple cathode sleeves (10); S3, filter out exhaust gas: During the high-efficiency desorption process, the compression pump (40) extracts air from the box (1) for filtration, and filters the waste gas generated by electrolysis in the box (1), thereby preventing the waste gas from overflowing and achieving waste gas removal; S4, discharge: The desorbed zinc element falls into the desorption bucket (2), and during the high-pressure flushing process of the nozzle (34), it is discharged along the desorption bucket (2) and collected centrally, thereby achieving the discharge of the zinc element.
