Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electrochemical metallurgy, and in particular relates to a vibration auxiliary scraping system for an electrolytic cathode. Background Art
[0002] Electrochemical metallurgy is a process for extracting or purifying metals using electrolytes. Electrochemical metallurgy typically utilizes electrolytic devices to extract and purify metals. While electrolytic devices vary depending on the reaction temperature and type of metal, they primarily consist of a cathode, an anode, and an electrolytic cell. During the electrolysis process, metal salts or consumable anodes are often used as the metal source. Metals are reduced at the cathode to produce single metals with unique morphologies, such as scaly or dendritic shapes. These can be used for gold, silver, copper, titanium, vanadium, and other metals.

After electrolysis, the furnace must be shut down to replace electrodes and collect the cathode product. This process requires repeated cooling and heating, resulting in energy loss. Furthermore, frequent furnace openings and adjustments to the gas system severely compromise the stability and cleanliness of the electrolysis environment. Utility Model Content

[0052] Some embodiments disclose a vibration-assisted scraping system for an electrolytic cathode, comprising:
[0053] The scraper has a circular central through-hole for being adapted to be mounted on the electrolytic cathode. One end face of the scraper forms a circular ring-shaped blade for scraping the electrolysis products on the electrolytic cathode. Typically, the electrolytic cathode is disposed in an electrolytic device, and the electrolytic cathode can be vertically moved in the electrolytic device by an automatic electrode lifting device. The electrolytic cathode can be adaptively mounted in the circular central through-hole of the scraper. During the vertical movement, the deposits on the electrolytic cathode interact with the scraper, breaking under the action of the scraper and separating from the cathode.
[0054] The scraper bracket is in the shape of a ring; the outer circle of the scraper bracket is adapted to the inner side of the cylindrical outer shell of the electrolysis device and is arranged to be movable along the axial direction of the electrolysis device, and the inner circle of the scraper bracket is adapted to the scraper and is used to set a fixed scraper; usually, in order to set the scraper, it is necessary to set a scraper bracket for mounting the scraper, and the scraper bracket is arranged in the shape of a ring so that its distal circle is adapted to the inner surface circle of the outer shell of the electrolysis device, and can move freely along the axial direction of the outer shell of the electrolysis device without hindering the scraper from scraping the cathode product; at the same time, the inner circle of the scraper bracket is adapted to the scraper, and the scraper is mounted on the inner side of the scraper bracket;
[0055] A vibration device is provided and connected to the upper part of the scraper bracket; the vibration device provided on the scraper bracket can drive the scraper bracket to vibrate vertically in the electrolysis device, and simultaneously drive the scraper to vibrate, thereby assisting the scraper in scraping the cathode deposits in a vibration manner;

Typically, in order to maintain a stable position of the vibration device, a connecting ring is provided to fixedly connect the upper end of the vibration device to the connecting ring. The connecting ring is also configured to adapt to the shape of the inner side of the cylindrical outer shell of the electrolysis device so that it can freely move along the axial direction of the electrolysis device under the drive of the vibration device, without hindering the scraper's operation of scraping cathode deposits.

[0058] A second vibration damping device has one end secured to the lower portion of the scraper support, and the other end secured to the inner side of the cylindrical outer shell of the electrolyzer. Typically, the second vibration damping device is located below the vibrating device to mitigate the impact of the vibration force of the vibrating device on the outer shell and other structural components of the electrolyzer.
[0059] In some embodiments, a vibration-assisted scraping system for an electrolytic cathode disclosed herein comprises multiple vibrating devices, evenly spaced along the annular surface of a scraper support.

For example, two to eight vibrating devices may be provided.
[0060] Some embodiments disclose a vibration-assisted scraping system for an electrolytic cathode, wherein the vibrating device is a pneumatic vibrator, comprising a vibrator body and an air pipe connected to the vibrator body. Typically, the vibrator body generates regular vertical vibrations within the outer shell of the electrolytic device via pressurized gas introduced through the air pipe.
[0061] Typically, when the electrolytic cathode is automatically pulled through the scraper and the scraper begins to contact the product layer, the pneumatically driven vibrator body starts spontaneously and applies force to the upper part of the scraper, driving the scraper to vibrate regularly within a certain amplitude, forming a physical crushing effect assisted by a vibration external field on the product surface; in order to avoid the introduction of additional gas impurities and ensure the stability of the internal environment of the electrolysis device, the starting gas source of the pneumatic vibrator is argon, and the working pressure is 0.5 to 1.5 MPa.
[0062] In some embodiments of the disclosed vibration-assisted scraping system for an electrolytic cathode, multiple first vibration damping devices are provided, evenly spaced along the annular surface of the connecting ring; multiple second vibration damping devices are provided, evenly spaced along the annular surface of the scraper support. Generally, multiple first vibration damping devices, for example, 2 to 8, can be provided depending on the operating requirements of the vibration device; multiple second vibration damping devices, for example, 2 to 8, can also be provided depending on the operating requirements of the vibration device.

[0065] a first damping spring; one end of the first damping spring is fixed to the upper portion of the connecting ring, and the other end of the first damping spring is fixed to the lower portion of the first fixing plate;
[0066] The first limiting collar is adapted to be mounted on the outside of the first damping spring. Generally, the first damping spring may be one or more, depending on the operating conditions of the vibration device. The first limiting collar includes two annular components that are nested and connected to each other, with free ends of the two annular components being fixed to the upper portion of the connecting ring and the lower portion of the first fixing plate, respectively.
[0067] The second vibration damping device comprises:
[0068] a second damping spring; one end of the second damping spring is fixed to the lower portion of the scraper bracket, and the other end of the second damping spring is fixed to the upper portion of the second fixing plate;
[0069] The second limiting collar is adapted to be mounted on the outside of the second damping spring; usually, the second damping spring can be set to one or more, and can be selected according to the working conditions of the vibration device; the second limiting collar includes two annular components that are nested and connected to each other, and the free ends of the two annular components are respectively fixed to the upper part of the second fixed plate and the lower part of the scraper bracket.
[0070] Some embodiments disclose a vibration-assisted scraping system for an electrolytic cathode, wherein the scraper is formed by connecting a plurality of arc-shaped scraper blades end to end in sequence. Typically, the scraper is in the form of a circular ring, and the center of the circular scraper is a circular through hole that can be fitted with the cathode. The circular central through hole takes the axis of the scraper as the center of the circle, and one end face of the circular scraper forms a circular blade. Typically, when the scraper is set on the cathode, one end of the circular blade is set to contact the cathode deposit, and the circular blade is used to interact with the deposit to separate the deposit from the cathode. In some embodiments, the scraper is formed by connecting a plurality of arc-shaped scraper blades end to end in sequence. The plurality of arc-shaped scraper blades have structures that fit together, such as mortise and tenon structures, and the ends are connected to each other in sequence to form a complete circular scraper. Typically, the plurality of arc-shaped scraper blades have the same shape and structure, such as 3, 4, 5, 6, or other arc-shaped scraper blades.
[0071] In some embodiments of the disclosed vibration-assisted scraping system for an electrolytic cathode, the surface of the circular blade has a serrated, corrugated, or trapezoidal shape. Generally, to strengthen the interaction between the circular blade surface of the scraper and the cathode deposits and increase contact stress, the shape of the circular blade surface can be appropriately modified so that a portion of the surface contacts the deposits, increasing stress at the contact point and facilitating deposit removal. For example, the blade surface can be configured to have a serrated, corrugated, or trapezoidal shape.
[0072] Some embodiments disclose a vibration-assisted scraping system for an electrolytic cathode, wherein the scraper is truncated cone-shaped, and the larger end surface of the truncated cone-shaped scraper forms a circular ring-shaped blade. Typically, the scraper can be set to a truncated cone-shaped shape, and the larger end surface of the truncated cone-shaped scraper forms a circular ring-shaped blade, which contacts the sediment and can increase the area of interaction with the sediment on the cathode surface; typically, the circular ring-shaped blade has a certain thickness, and the circular ring-shaped blade within this thickness range is cylindrical, and the cylindrical side is configured to fit the inner surface of the scraper holder, facilitating a fixed connection and fixing the scraper on the scraper holder; at the same time, the diameter of the circular ring-shaped blade of the scraper gradually decreases as it extends downward from the side, forming a smaller end surface, so that the scraper as a whole is truncated cone-shaped. Typically, the thickness of the circular ring-shaped blade can be set between 0.5 and 3 cm.
