Abstract
Description
Technical Field
[0001] This utility model relates to the field of recycling and processing carbon blocks from electrolytic aluminum anodes, and more specifically, to a residual anode depressurization machine. Background Technology
[0002] In the electrolytic aluminum anode assembly line, in order to reduce anode waste and improve the utilization rate of anode carbon blocks, the anode replacement cycle is usually extended. As the electrolysis cycle is extended, the thickness and other dimensions of the remaining residual carbon blocks are smaller. When using a residual carbon pressing machine to peel the incompletely electrolyzed residual carbon blocks from the steel claws of the guide rod, the contact area between the upper and lower pressure heads of the residual carbon pressing machine and the residual carbon blocks is small. This makes the residual carbon blocks prone to slippage under the clamping and squeezing of the upper and lower pressure heads, resulting in incomplete removal of the residual carbon blocks from the steel claws. This requires manual removal by hammering with a sledgehammer, increasing labor intensity and reducing pressing efficiency. Utility Model Content
[0003] This invention aims to solve the technical problem of low desorption efficiency of residual carbon blocks in related technologies.
[0004] This utility model provides a residual electrode pressing and stripping machine, including a first pressing arm, a second pressing arm, a limiting baffle, and a machine body. The first pressing arm and the second pressing arm are hinged together. The first pressing arm and the second pressing arm are used to rotate relative to each other so that the first pressing arm and the second pressing arm respectively press and contact the two end faces of the residual electrode carbon block along its thickness direction. The limiting baffle is disposed on the machine body and is used to limit the contact with the side of the residual electrode carbon block away from the hinge point of the first pressing arm and the second pressing arm.
[0005] Optionally, the machine body has a side plate, one side of which is provided with the first pressure arm and the second pressure arm, and the side of the side plate near the first pressure arm and the second pressure arm is provided with a wedge-shaped surface, and the limiting baffle has a wedge-shaped mating surface that matches the wedge-shaped surface.
[0006] Optionally, the first pressure arm includes a first pressure handle and a first pressure head connected to each other, and the second pressure arm includes a second pressure handle and a second pressure head connected to each other. The first pressure handle and the second pressure handle are hinged together, and the first pressure head and the second pressure head are respectively used to press and contact the corresponding end faces of the residual carbon block.
[0007] Optionally, the end of the first pressure handle away from the first pressure head is rotatably connected to the machine body. The first pressure handle is used to rotate relative to the machine body so that the first pressure head extends between two adjacent claw portions of the steel claw of the upper anode guide rod of the residual carbon block and presses against one end face of the residual carbon block along its thickness direction.
[0008] Optionally, the first pressure head and / or the second pressure head includes a pressure head body and a thickened layer connected to each other, wherein the thickened layer is provided along the side of the pressure head body facing the residual carbon block.
[0009] Optionally, the side of the second pressure head facing the first pressure head is provided with a cutting edge, and the cutting edge is wavy;
[0010] And / or, let the hinge point between the second pressure handle and the first pressure handle be the first hinge point, and the thickness of the second pressure head gradually increases from the end near the first hinge point toward the direction away from the first hinge point.
[0011] Optionally, the end of the first pressure head away from the first pressure handle is provided with a guide arc surface.
[0012] Optionally, the residual electrode depressurizer further includes a first driving device and a second driving device, wherein the first driving device is driven connected to the first pressure handle and the second driving device is driven connected to the second pressure handle.
[0013] Optionally, the first driving device is a first hydraulic rod, the second driving device is a second hydraulic rod, the two ends of the first hydraulic rod are respectively connected to the first pressure handle and the machine body, and the two ends of the second hydraulic rod are respectively connected to the second pressure handle and the first pressure handle.
[0014] Optionally, both the first pressure arm and the second pressure arm are bent arms, with the bent portion of the first pressure arm and the bent portion of the second pressure arm hinged to each other, and the portions of the first pressure arm and the second pressure arm, excluding the hinge point, extend in a direction away from each other.
[0015] The residual electrode depressurization machine of this invention has at least the following advantages compared with the prior art:
[0016] The first and second pressure arms are hinged together and rotate relative to each other to press and contact the carbon residue block in the thickness direction, i.e., the upper and lower end faces, to clamp the carbon residue block. By controlling the clamping force, the carbon residue block is crushed and detached from the anode guide rod's steel claw. Since the limiting baffle is set on the machine body and is used to limit the contact with the side of the carbon residue block away from the hinge point of the first and second pressure arms, the carbon residue block will not move away from the hinge point of the first and second pressure arms during the clamping and squeezing process, i.e., it will not slip sideways. This ensures that the carbon residue block can be completely removed, eliminating the need for subsequent manual knocking and cleaning steps, reducing labor intensity, and improving the removal efficiency.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] In addition, it should be noted that in the description of this utility model, the terms and nouns in each embodiment, such as "upper," "lower," "front," and "rear," which indicate the location, are only used to simplify the description of the positional relationship based on the accompanying drawings. They do not mean that the components and devices referred to must be operated in accordance with the specific location and limited operation, method, and structure in the specification. Such directional terms do not constitute a limitation on this utility model.
[0024] This paper establishes a YZ coordinate system, where the Y-axis represents the left-right direction, with the positive direction of the Y-axis representing the left and the negative direction representing the right; the Z-axis represents the up-down direction, with the positive direction of the Z-axis representing the up and the negative direction representing the down. It should be noted that the aforementioned Y and Z axis representations are merely for ease of description and simplification of this invention, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0025] like Figure 1As shown, an embodiment of the present invention provides a residual electrode pressing and stripping machine, comprising a first pressing arm 1, a second pressing arm 2, a limiting baffle 3, and a machine body. The first pressing arm 1 and the second pressing arm 2 are hinged together. The first pressing arm 1 and the second pressing arm 2 are used to rotate relative to each other so that the first pressing arm 1 and the second pressing arm 2 respectively press and contact the two end faces of the residual electrode carbon block 7 along its thickness direction. The limiting baffle 3 is disposed on the machine body and is used to limit the contact with the side of the residual electrode carbon block 7 away from the hinge point of the first pressing arm 1 and the second pressing arm 2.
[0026] The residual electrode descraping machine in this embodiment can be used to descramble the residual electrode carbon block 7 in aluminum electrolysis. In aluminum electrolysis, one end of the anode guide rod 9 can be provided with an anode guide rod steel claw 8. The anode guide rod steel claw 8 includes multiple claw parts arranged at intervals, and each claw part is connected to one end face of the residual electrode carbon block 7 along its thickness direction.
[0027] The first pressure arm 1 and the second pressure arm 2 can be bent, and their shapes can be different. The first pressure arm 1 and the second pressure arm 2 are rotatably connected around the first hinge point a, so that they can be opened and closed by rotating relative to each other, which is convenient for clamping or releasing the residual carbon block 7.
[0028] The rotation axes of the first pressure arm 1 and the second pressure arm 2 are perpendicular to the YZ plane. The anode guide rod 9 with the residual carbon block 7 can be placed in the pressing and depressing position of the residual carbon block along the Z direction. The first pressure arm 1 and the second pressure arm 2 can rotate relative to each other to press and contact the end face of the residual carbon block 7 along its thickness direction, that is, the upper and lower end faces. The limiting baffle 3 is installed on the machine body. When the residual carbon block 7 is placed in the pressing and unloading station, the limiting baffle 3 and the hinge points of the first pressing arm 1 and the second pressing arm 2 are respectively located on both sides of the residual carbon block 7. That is, the limiting baffle 3 is located on the side of the residual carbon block 7 along the positive Y-axis, and the first hinge point a is located on the side of the residual carbon block 7 along the negative Y-axis. When the first pressing arm 1 and the second pressing arm 2 rotate around the first hinge point a to clamp the residual carbon block 7, the limiting baffle 3 contacts the side of the residual carbon block 7 away from the first hinge point a, that is, the side along the positive Y-axis, to restrict the residual carbon block 7 from moving in the direction away from the first hinge point a, thereby achieving anti-slip.
[0029] In this embodiment, the first pressure arm 1 and the second pressure arm 2 are hinged together. The first pressure arm 1 and the second pressure arm 2 rotate relative to each other to press and contact the residual carbon block 7 in the thickness direction, that is, the upper and lower end faces, so as to achieve clamping of the residual carbon block 7. By controlling the clamping force, the residual carbon block 7 is crushed and detached from the anode guide rod steel claw 8. Since the limiting baffle 3 is set on the machine body and is used to limit the contact with the side of the residual carbon block 7 away from the hinge point of the first pressure arm 1 and the second pressure arm 2, that is, away from the first hinge point a, the residual carbon block 7 will not move in the direction away from the hinge point of the first pressure arm 1 and the second pressure arm 2 during the clamping and squeezing process, that is, it will not slip sideways, ensuring that the residual carbon block 7 can be squeezed out cleanly, eliminating the subsequent manual knocking and cleaning steps, reducing the labor intensity and improving the squeezing efficiency.
[0030] like Figure 1 As shown, optionally, the machine body has a side plate 4, one side of the side plate 4 is provided with the first pressure arm 1 and the second pressure arm 2, the side plate 4 is provided with a wedge-shaped surface 41 on the side near the first pressure arm 1 and the second pressure arm 2, and the limiting baffle 3 has a wedge-shaped mating surface that matches the wedge-shaped surface 41.
[0031] Specifically, the machine body has a side plate 4 near the pressing station. The side plate 4 can be set vertically. On one side of the side plate 4 in the left-right direction, such as the right side, there is a first pressing arm 1 and a second pressing arm 2. On the side plate 4 in the negative direction of the Y axis, there is a wedge-shaped surface 41. The wedge-shaped surface 41 gradually tilts from top to bottom away from the first pressing arm 1 and the second pressing arm 2. The limiting baffle 3 can be a triangular plate with a wedge-shaped mating surface.
[0032] In this embodiment, the limiting baffle 3 is installed in conjunction with the side plate 4 through a wedge-shaped mating surface and a wedge-shaped surface 41, which reduces the space occupied by the limiting baffle 3 and the side plate 4 along the Y direction, making the overall arrangement of the residual electrode depressurizer more compact. In addition, the wedge-shaped surface 41 on the side plate 4 gradually tilts from top to bottom away from the first pressure arm 1 and the second pressure arm 2, which can avoid the residual electrode carbon block 7 and the second pressure arm 2, so that the second pressure arm 2 will not interfere with the side plate 4 when it moves towards the bottom of the residual electrode carbon block 7.
[0033] like Figure 1 As shown, optionally, the first pressure arm 1 includes a first pressure handle 11 and a first pressure head 12 connected to each other, and the second pressure arm 2 includes a second pressure handle 21 and a second pressure head 22 connected to each other. The first pressure handle 11 and the second pressure handle 21 are hinged together, and the first pressure head 12 and the second pressure head 22 are respectively used to press and contact the corresponding end faces of the residual carbon block 7.
[0034] Specifically, the first pressure handle 11 and the first pressure head 12 can be integrally formed, and the second pressure handle 21 and the second pressure head 22 can be integrally formed, simplifying the structure and improving strength. The first pressure handle 11 and the second pressure handle 21 are used for operation and facilitate connection to the drive device described below. The first pressure handle 11 of the first pressure arm 1 and the second pressure handle 21 of the second pressure arm 2 are hinged to avoid damaging the first pressure head 12 and the second pressure head 22. The first pressure head 12 and the second pressure head 22 are only used to clamp the broken carbon residue 7. During operation, by driving the first pressure handle 11 and / or the second pressure handle 21 to rotate, the first pressure head 12 and the second pressure head 22 can clamp the carbon residue 7.
[0035] One end of the second pressure handle 21 is bent away from the first pressure arm 1 to connect with the second pressure head 22. When the first pressure head 12 and the second pressure head 22 rotate toward each other, they can rotate to be parallel to each other so that they can smoothly press and contact the upper and lower end faces of the residual carbon block 7.
[0036] like Figure 1 As shown, optionally, both the first pressure arm 1 and the second pressure arm 2 are bent arms. The bent parts of the first pressure arm 1 and the second pressure arm 2 are hinged to each other, and the parts of the first pressure arm 1 and the second pressure arm 2, except for the hinge points, extend in a direction away from each other. In this way, the first pressure arm 1 and the second pressure arm 2 do not need to be hinged by crossing, so that the first pressure arm 1 and the second pressure arm 2 can easily clamp the residual carbon block 7, and the driving mechanism of the first pressure arm 1 and the driving mechanism of the second pressure arm 2 (hereinafter the first driving device and the second driving device) can be arranged between the first pressure arm 1 and the second pressure arm 2, and it is not easy for motion interference to occur.
[0037] For example, the shapes of the first pressure arm 1 and the second pressure arm 2 may be different, and the number of bends in the first pressure arm 1 and the second pressure arm 2 may be inconsistent. For instance, the first pressure arm 1 may have one bend, with the two mutually bent segments arranged vertically to form an L-shape; the second pressure arm 2 may have two bends, with the three mutually bent segments connected to form a Z-shape; the bend of the first pressure arm 1 may be hinged to one of the bends of the second pressure arm 2; the second pressure handle 21 may be Z-shaped, with one Z-shaped segment of the second pressure handle 21 connected to the second pressure head 22; when the first pressure arm 1 and the second pressure arm 2 rotate to clamp the residual carbon block 7, the first pressure handle 11 of the first pressure arm 1 is arranged vertically, and the lower end of the first pressure handle 11 is connected to... A first pressure head 12 is horizontally positioned. The second pressure handle 21 of the second pressure arm 2 is located at both ends in a roughly horizontal state, and one of its ends is connected to the horizontally positioned second pressure head 22. The Z-shaped second pressure handle 21 has two bends. The bend away from the second pressure head 22 is rotatably connected to the lower end of the first pressure handle 11 around the first hinge point a. Compared with the scheme where the first pressure arm 1 and the second pressure arm 2 are arranged in a cross configuration, interference between the first pressure arm 1 and the second pressure arm 2 during rotation can be avoided. Moreover, the space formed between the first pressure handle 11 of the first pressure arm 1 and the second pressure handle 21 of the second pressure arm 2 can be conveniently installed to accommodate the drive mechanism (first drive device and second drive device).
[0038] like Figure 1 As shown, optionally, the end of the first pressure handle 11 away from the first pressure head 12 is rotatably connected to the machine body. The first pressure handle 11 is used to rotate relative to the machine body so that the first pressure head 12 extends between two adjacent claw portions of the upper anode guide rod steel claw 8 of the residual carbon block 7 and contacts one end face of the residual carbon block 7 along its thickness direction.
[0039] Specifically, the end of the first pressure handle 11 away from the first pressure head 12 is rotatably connected to the machine body around the second hinge point b. The second hinge point b is far from the first pressure head 12. The first pressure handle 11 can drive the first pressure head 12 to move a greater distance by rotating a small angle around the second hinge point b. The driving of the first pressure handle 11 is more labor-saving.
[0040] During operation, the first pressure arm 1 can first rotate around the machine body with the second hinge point b as the center under the drive of external force, so that the first pressure head 12 is inserted into the gap of the claw of the anode guide rod steel claw 8 and contacts the upper end face of the residual carbon block 7 (the end face of the residual carbon block 7 facing the anode guide rod 9). The position of the second hinge point b is fixed relative to the machine body, which can ensure that when the residual carbon block 7 is placed in the pressing position of the residual carbon pressing machine, the first pressure arm 1 can accurately extend into the gap between the two adjacent claws of the anode guide rod steel claw 8 and contact the end face of the residual carbon block 7 after rotating around the second hinge point b. Then, the second pressure arm 2 can rotate around its hinge point with the first pressure arm 1, i.e., the first hinge point a, under the drive of external force, so that the second pressure head 22 moves towards the residual carbon block 7 until it contacts the lower end face of the residual carbon block 7. The second pressure arm 2 continues to rotate and can squeeze the residual carbon block 7 upward until the residual carbon block 7 breaks and falls off the anode guide rod steel claw 8.
[0041] like Figure 2 As shown, optionally, the first pressure head 12 and / or the second pressure head 22 include a pressure head body 221 and a thickening layer 222 connected to each other, wherein the pressure head body 221 is provided with the thickening layer 222 along the side facing the residual carbon block 7.
[0042] Here, the first pressure head 12 and / or the second pressure head 22 include an interconnected pressure head body 221 and a thickened layer 222, including three cases: the first pressure head 12 includes an interconnected pressure head body 221 and a thickened layer 222, or the second pressure head 22 includes an interconnected pressure head body 221 and a thickened layer 222, or both the first pressure head 12 and the second pressure head 22 include an interconnected pressure head body 221 and a thickened layer 222.
[0043] The following description uses the second pressure head 22, which includes an interconnected pressure head body 221 and a thickened layer 222, as an example: The pressure head body 221 can be regarded as the lower pressure head of an existing residual carbon pressing machine. By providing a thickened layer 222 on the side of the pressure head body 221 facing the residual carbon block 7, the thickness of the second pressure head 22 in this embodiment is greater than the thickness of the existing lower pressure head in the direction perpendicular to the contact surface with the residual carbon block 7. When the second pressure handle 21 is driven to move by the second driving device described below, the second pressure head 22 can squeeze and contact the residual carbon block 7 when the second driving device drives the second pressure handle 21 to move a small distance. This reduces the driving stroke of the second driving device, improves driving stability, ensures thorough pressing and removal, and avoids the residual carbon block 7 being not cleanly pressed and removed because the movement stroke required for the second pressure handle 21 to squeeze the residual carbon block 7 exceeds the driving stroke of the second driving device.
[0044] like Figure 2 As shown, optionally, the side of the second pressure head 22 facing the first pressure head 12 is provided with a cutting edge 223, and the cutting edge 223 is wavy.
[0045] It should be noted that although the first pressure head 12 contacts the upper surface of the residual carbon block 7, its main function is to insert the anode guide rod steel claw 8 and fix the anode guide rod steel claw 8. During the pressing and depressing process of the residual carbon block 7, the crushing and extrusion mainly relies on the second pressure head 22. Since the second pressure head 22 contacts the residual carbon block 7 through its cutting edge 223, by designing the cutting edge 223 as a wave shape, the contact area between it and the residual carbon block 7 can be effectively reduced. The pressure on the residual carbon block 7 is more concentrated and greater, making it easier to crush the residual carbon block 7. Moreover, compared with a straight cutting edge, the wave-shaped cutting edge 223 is more convenient for slag discharge, avoids wear and curling of the cutting edge 223, and improves the service life of the second pressure head 22, i.e. the entire residual carbon depressor.
[0046] The cutting edge 223 can undergo appropriate heat treatment to achieve high strength and hardness.
[0047] Optionally, the thickness of the second pressure head 22 gradually increases from the end near the first hinge point a toward the direction away from the first hinge point a. That is, the end of the second pressure head 22 away from the first hinge point a has a larger thickness, so that when the second pressure head 22 rotates toward the residual carbon block 7, it can apply a larger and more stable extrusion force to the residual carbon block 7, making it easier to crush the residual carbon block 7 and preventing the residual carbon block 7 from slipping during the extrusion process.
[0048] like Figure 1 As shown, optionally, the end of the first pressure head 12 away from the first pressure handle 11 is provided with a guide arc surface 121.
[0049] In this embodiment, a guide arc surface 121 is provided at the end of the first pressure head 12 away from the first pressure handle 11. The guide arc surface 121 can be bent upward, and the first pressure head 12 can be smoothly inserted between two adjacent claws of the anode guide rod steel claw 8 under the guidance of the guide arc surface 121.
[0050] Optionally, the residual electrode depressurizer further includes a first driving device and a second driving device, wherein the first driving device is drivenly connected to the first pressure handle 11, and the second driving device is drivenly connected to the second pressure handle 21.
[0051] Here, by using a first driving device to drive the first pressure handle 11, the first pressure arm 1 is rotated around the second hinge point b. By using a second driving device to drive the second pressure handle 21, the second pressure arm 2 rotates relative to the first pressure arm 1 around the first hinge point a, making the motion control of the first pressure arm 1 and the second pressure arm 2 more convenient. The first driving device and the second driving device can be electric driving devices, hydraulic driving devices, etc.
[0052] like Figure 1As shown, optionally, the first driving device is a first hydraulic rod 5, and the second driving device is a second hydraulic rod 6. The two ends of the first hydraulic rod 5 are respectively connected to the first pressure handle 11 and the machine body, and the two ends of the second hydraulic rod 6 are respectively connected to the second pressure handle 21 and the first pressure handle 11.
[0053] Specifically, the first driving device uses a first hydraulic rod 5, and the second driving device uses a second hydraulic rod 6, which makes the driving relatively stable and the driving form relatively simple.
[0054] One end of the first hydraulic rod 5 can be rotatably connected to the end of the first pressure handle 11 near the first pressure head 12, and the other end is rotatably connected to the machine body. The first pressure arm 1 can be stably rotated around its second hinge point b with the machine body under the drive of the first hydraulic rod 5, and the first hydraulic rod 5 only needs to provide a small driving force, which is relatively labor-saving.
[0055] One end of the second hydraulic rod 6 is rotatably connected to the first pressure handle 11 around the third hinge point c, and the other end is rotatably connected to the second pressure handle 21 around the fourth hinge point d. The end of the first pressure handle 11 near the first pressure head 12 is rotatably connected to the middle of the second pressure handle 21 around the first hinge point a. The first hinge point a, the third hinge point c, and the fourth hinge point d are arranged in a triangle. The first pressure handle 11, the second pressure handle 21, and the second hydraulic rod 6 form a triangular structure with good stability. The second pressure handle 21 can stably rotate around the first hinge point a under the drive of the second hydraulic rod 6 to apply a stable extrusion force to the residual carbon block 7. Furthermore, the connection point between the first pressure handle 11 and the second hydraulic rod 6 is located at the end of the first pressure handle 11 away from the first pressure head 12, and the connection point between the second pressure handle 21 and the second hydraulic rod 6 is located at the end of the second pressure handle 21 away from the second pressure head 22, so that the triangle formed by the first hinge point a, the third hinge point c, and the fourth hinge point d is larger, ensuring the connection stability of the first pressure arm 1 and the second pressure arm 2.
[0056] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
