Description

Technical Field

[0001] This utility model relates to the field of a low-level electrolyte circulation tank capable of removing air bubbles, and particularly to a low-level electrolyte circulation tank capable of removing air bubbles. Background Technology

[0002] During the copper electrolytic refining process, the prepared electrolyte contains air, and the temperature of the electrolyte is between 50 and 60°C. At this temperature, the evaporated water vapor, the original air, and the electrolyte also contain residual ferrous ions, hydroxide ions, sulfate ions, and other impurities. These impurities are smaller than divalent copper ions and float in the electrolyte, while copper ions, which are denser, float to the bottom, resulting in a significant difference in the composition of the upper and lower electrolytes.

[0003] Chinese Patent CN215828886U discloses a low-level electrolyte circulation tank capable of removing air bubbles. The tank includes a shell with a lid on top. Multiple electrolyte inlet pipes are located on the top of the lid. A first electrolyte degassing plate and a second electrolyte degassing plate are fixed inside the shell. A slag outlet is located on the side wall of the shell corresponding to the separation and settling tank. A bubble-breaking component is fixed on the first electrolyte degassing plate. This technical solution can break up air bubbles in the electrolyte, ensuring uniform copper ions and impurities in the electrolyte, thus obtaining high-quality copper plates after electrolytic refining.

[0004] However, the above technical solution has the following shortcomings: In this technical solution, the air bubbles are broken by a filter screen made of 316L wire, but some air bubbles float on the surface of the electrolyte and the air bubble walls are relatively thick, so they stick to the surface of the filter screen. As a result, air bubbles are always distributed on the filter screen, and the sediment contained in the air bubbles can easily be carried back into the electrolyte, resulting in poor quality of electrolytic copper. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a low-level electrolyte circulation tank that uses the gravitational potential energy of the electrolyte to sequentially drive the drive component and the bubble-breaking component to break up the bubbles, and then uses the shaking rod to generate vibration to further remove the remaining bubbles.

[0006] The technical solution of this utility model is an electrolyte low-level circulation tank capable of removing bubbles, comprising: a shell with a cover, the cover being connected to an air inlet pipe, an air outlet pipe and multiple feed pipes, and an inclined downward upper guide plate and a lower guide plate on the shell; a drive assembly disposed on the shell; and a bubble-breaking assembly comprising a bubble-breaking shaft rotatably disposed on the shell, multiple rows of bubble-breaking rods arranged circumferentially on the bubble-breaking shaft, a fixed frame disposed on the shell, a filter plate placed on the fixed frame, a vibrating rod disposed on the fixed frame, a rocking rod rotatably disposed on the shell, and a counterweight at the bottom of the rocking rod; the drive assembly is drivenly connected to the bubble-breaking shaft, and both ends of the fixed frame are respectively connected to the upper guide plate and the lower guide plate.

[0007] Preferably, a sealing gasket is provided between the fixing frame and the housing, and the sealing gasket is distributed at the vibrating rod.

[0008] Preferably, a clamping block is provided on the fixed frame, a sliding rod is slidably provided on the clamping block, a pushing block is provided on the sliding rod, a spring is provided between the pushing block and the clamping block, and the upper and lower ends of the pushing block are inclined in the direction away from the filter plate.

[0009] Preferably, the drive assembly includes a drive rod rotatably mounted on the housing, a drive cylinder mounted on the drive rod, a transmission pulley a and a handwheel coaxially mounted on the drive rod, a transmission pulley b mounted on the bubble-breaking shaft, and a transmission belt mounted on the transmission pulley a and the transmission pulley b; the drive cylinder has drive blades distributed along its outer circumferential surface.

[0010] Preferably, the cover is provided with a fan and multiple one-way valve assemblies, with the fan located at the air outlet pipe and the multiple one-way valve assemblies correspondingly located at the air inlet pipe and multiple feed pipes.

[0011] Preferably, the one-way valve assembly includes a rotating shaft disposed on the housing, a sealing plate rotatably disposed on the rotating shaft, and a return spring disposed on the rotating shaft and connected to the sealing plate.

[0012] Preferably, the bottom end face of the housing slopes upward toward the air outlet from multiple corners.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] In use, the user feeds the electrolyte into the housing through the feed pipe. The electrolyte drives the drive assembly to start, which in turn drives the bubble-breaking shaft to rotate. The bubble-breaking shaft drives multiple bubble-breaking rods to break the bubbles, thus eliminating most of them. Then, the user pushes the rocking rod, which swings left and right under the action of the counterweight. The rocking rod swings left and right to collide with the bubble-breaking shaft and the vibrating rod. The vibrating rod drives the fixed frame and the filter plate to vibrate in sequence. During the vibration, the bubble walls gradually thin until they break, thus breaking some bubbles that have missed the bubble-breaking rods and are attached to the filter plate, thereby improving the quality of the electrolyte.

[0021] Example 1

[0022] like Figures 1-5As shown, this embodiment proposes a low-level electrolyte circulation tank capable of removing bubbles, comprising a shell 1, a drive assembly, and a defoaming assembly. A cover 2 is provided on the shell 1, and an air inlet pipe 4, an air outlet pipe 5, and multiple feed pipes 3 are connected to the cover 2. An inclined upper guide plate 8 and a lower guide plate 20 are provided on the shell. The drive assembly is mounted on the shell 1. The defoaming assembly includes a defoaming shaft 11 rotatably mounted on the shell 1, multiple rows of defoaming rods 12 arranged circumferentially on the defoaming shaft 11, a fixing frame 14 mounted on the shell 1, a filter plate 15 placed on the fixing frame 14, and a filter plate 15 mounted on the fixing frame 14. The vibrating rod 24 on the 4, the rocking rod 21 rotatably mounted on the housing 1, and the counterweight 22 mounted at the bottom of the rocking rod 21; the driving assembly is driven to connect with the bubble-breaking shaft 11, and the two ends of the fixing frame 14 are respectively connected to the upper guide plate 8 and the lower guide plate 20. The electrolyte circulation mode and slag discharge mode inside the housing 1 can adopt the specific working mode of the referenced document. The bubble-breaking rod 12 has a blade along the electrolyte flow direction to increase the pressure when the bubble comes into contact with the bubble-breaking rod 12, and to prevent the bubble from sliding towards both sides of the bubble-breaking rod 12, which would prevent the bubble from being broken. Multiple rows of bubble-breaking rods 12 are staggered.

[0023] In this embodiment, the user feeds the electrolyte into the housing 1 through the feed pipe 3. The electrolyte drives the drive assembly to start, which in turn drives the bubble-breaking shaft 11 to rotate. The bubble-breaking shaft 11 drives multiple bubble-breaking rods 12 to break the bubbles, thereby eliminating most of the bubbles. Then, the user pushes the rocking rod 21, which swings left and right under the action of the counterweight 22. The rocking rod 21 swings left and right to collide with the bubble-breaking shaft 11 and the vibrating rod 24. The vibrating rod 24 drives the fixed frame 14 and the filter plate 15 to vibrate in sequence. During the vibration, the bubble walls gradually thin until they break, thereby breaking some bubbles that have missed the bubble-breaking rods 12 and are attached to the filter plate 15, thus improving the quality of the electrolyte.

[0024] Example 2

[0025] like Figures 2-4 As shown, in this embodiment, a low-level electrolyte circulation tank capable of removing air bubbles is proposed. Compared with Embodiment 1, in this embodiment, a sealing gasket 23 is provided between the fixing frame 14 and the housing 1, and the sealing gasket 23 is distributed at the vibrating rod 24.

[0026] A clamping block 16 is provided on the fixed frame 14, a sliding rod 17 is slidably provided on the clamping block 16, a pushing block 18 is provided on the sliding rod 17, a spring 19 is provided between the pushing block 18 and the clamping block 16, and the upper and lower ends of the pushing block 18 are inclined in the direction away from the filter plate 15.

[0027] In this embodiment, the sealing gasket 23 separates the interior of the housing 1 from the external environment and prevents gas from leaking out through the gap between the housing 1 and the fixing frame 14 during vibration. When the user places the filter plate 15, the inclined push block 18 can improve the smoothness of the filter plate 15, and the spring 19 pushes the push block 18 to the position of the filter plate 15.

[0028] Example 3

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment proposes a low-level electrolyte circulation tank capable of removing bubbles. Compared with Embodiment 1, in this embodiment, the driving assembly includes a driving rod 9 rotatably mounted on the housing 1, a driving cylinder 10 mounted on the driving rod 9, a transmission pulley a and a handwheel 27 coaxially mounted on the driving rod 9, a transmission pulley b25 mounted on the bubble-breaking shaft 11, and a transmission belt mounted on the transmission pulley a and the transmission pulley b25; the driving cylinder 10 has driving blades distributed along its outer circumferential surface.

[0030] In this embodiment, the falling electrolyte causes the drive blades to move along the drive cylinder 10 as the axis, which in turn causes the drive rod 9 to rotate. The drive rod 9 drives the bubble-breaking shaft 11 to rotate via the transmission belt, thereby breaking the bubbles by recovering the gravitational potential energy of the electrolyte.

[0031] Example 4

[0032] like Figure 1 , Figure 2 and Figure 5 As shown in the figure, the electrolyte low-level circulation tank that can remove bubbles proposed in this embodiment has the following features compared to the first embodiment: in this embodiment, the cover 2 is provided with a fan 7 and multiple one-way valve assemblies 6. The fan 7 is distributed at the air outlet pipe 5, and the multiple one-way valve assemblies 6 are distributed one-to-one at the air inlet pipe 4 and multiple feed pipes 3.

[0033] The one-way valve assembly 6 includes a rotating shaft 61 mounted on the housing 1, a sealing plate 62 rotatably mounted on the rotating shaft 61, and a return spring 63 mounted on the rotating shaft 61 and connected to the sealing plate 62. The bottom end face of the housing 1 slopes upward toward the air outlet pipe 5 from multiple corners.

[0034] In this embodiment, the fan 7 delivers the gas inside the shell 1 into the acid mist treatment tower, and the bottom end face of the cover 2 is specially treated so that the gas moves to the outlet pipe 5 as it floats upward, thereby reducing the harmful gas remaining in the shell 1 and preventing impurities contained in the gas from falling back into the electrolyte.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
