Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis cell technology, and specifically to a ruler device for aluminum electrolysis cells. Background Technology

[0002] Cathode paste, also known as tamping paste or binding paste, is a carbon material used in the cathode lining structure of aluminum electrolytic cells. During the construction of the carbon paste binding layer in aluminum electrolytic cells, uneven carbon paste layering often leads to deviations in the compaction and thickness of the binding. This is particularly problematic when constructing the carbon paste on the large sloping areas around the lining, where the overall thickness is greater and multiple layers are required. Furthermore, the sloping nature of the carbon paste layer makes it difficult to control its thickness, severely hindering the construction quality in this area. Therefore, a straightedge device for aluminum electrolytic cells is urgently needed to solve these problems. Utility Model Content

[0003] To address the technical challenge of controlling the thickness of the carbon paste layer on the sloping perimeter of an electrolytic cell lining, which is difficult due to its large overall thickness and the need for multiple layers of reinforcement, and whose thickness is severely hampered by the sloping surface, this invention provides a straightedge device for aluminum electrolytic cells. This device is simple in structure and easy to operate. The irregularly shaped straightedge precisely smooths the carbon paste layer, ensuring a consistent overall thickness. When inspecting the flatness of the carbon paste layer on the sloping lining of the aluminum electrolytic cell, the device quickly assesses the appearance quality of the reinforced carbon paste by checking the gap between the straightedge and the surface, significantly improving the construction quality of the carbon paste on the sloping lining of the aluminum electrolytic cell.

[0004] This utility model provides a guide ruler device for an aluminum electrolytic cell, including a moving mechanism and a scraping mechanism. The moving mechanism is movably mounted on the side carbon block of the aluminum electrolytic cell. The scraping mechanism includes a vertical arm and a shaped guide ruler. The vertical arm is adjustablely mounted on the moving mechanism and is located to the side of the side carbon block of the aluminum electrolytic cell. The shaped guide ruler is fixedly mounted at the bottom of the vertical arm and is located above the inner lining slope of the aluminum electrolytic cell.

[0005] Furthermore, the moving mechanism includes an inverted L-shaped frame, horizontal wheels, and vertical wheels. The horizontal wheels and vertical wheels are respectively rotatably disposed on the top and side of the inverted L-shaped frame. The horizontal wheels contact the upper surface of the side carbon block of the aluminum electrolysis cell and move thereon. The vertical wheels contact the side surface of the side carbon block of the aluminum electrolysis cell and move thereon. The inverted L-shaped frame is located to the side of the side carbon block of the aluminum electrolysis cell.

[0006] Furthermore, the inverted L-shaped frame includes a wheel rod and a triangular wheel frame. The wheel rod is fixedly mounted on the top of the triangular wheel frame and is perpendicular to the triangular wheel frame. The wheel rod is located above the side carbon block of the aluminum electrolysis cell and is parallel to it. There is one horizontal wheel, which is rotatably mounted on the wheel rod. The triangular wheel frame is located to the side of the side carbon block of the aluminum electrolysis cell and is parallel to it. There are two vertical wheels, which are rotatably mounted at both ends of the bottom of the triangular wheel frame.

[0007] Furthermore, a guide sleeve is fixedly installed on the side of the bottom of the triangular wheel frame away from the vertical wheel, and the top of the vertical arm passes through the guide sleeve and is adjustablely mounted on the guide sleeve via a set screw. When the set screw is loosened, the vertical arm moves up and down relative to the guide sleeve; when the set screw is tightened, the vertical arm is fixed on the guide sleeve.

[0008] Furthermore, the guide sleeve is provided with two screw holes, and there are two set screws, each of which passes through a screw hole and is pressed against the top of the vertical arm. When the set screw is released, the set screw moves away from the top of the vertical arm and the screw hole, and then the vertical arm moves up and down relative to the guide sleeve. When the set screw is locked onto the guide sleeve through the screw hole and pressed against the top of the vertical arm, the vertical arm is fixed to the guide sleeve.

[0009] Furthermore, the vertical arm is provided with scale lines. The scale lines facilitate the adjustment of the extension and retraction length of the vertical arm, which in turn facilitates the adjustment of the position of the irregular straightedge. The irregular straightedge, in turn, precisely controls the thickness of each carbon paste layer on the inner lining slope of the aluminum electrolysis cell.

[0010] Furthermore, the irregularly shaped straightedge includes a first crossbar and a second crossbar fixedly connected, with an obtuse angle formed between them. The first crossbar is parallel to the left end of the inner lining slope of the aluminum electrolytic cell, and the second crossbar is parallel to the right end of the inner lining slope. The first and second crossbars match the shape of the inner lining slope of the aluminum electrolytic cell. The first and second crossbars precisely level the carbon paste layer, ensuring a consistent overall thickness.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model relates to a straightedge device for aluminum electrolytic cells. It has a simple structure and is easy to operate. The irregularly shaped straightedge accurately smooths the carbon paste layer, ensuring that the overall thickness of the carbon paste layer remains consistent. When it is necessary to inspect the flatness of the carbon paste layer on the inner lining slope of the aluminum electrolytic cell, the appearance quality after the carbon paste is secured can be quickly determined by checking the gap between the irregularly shaped straightedge and the surface of the carbon paste layer. This greatly improves the construction quality of the carbon paste on the inner lining slope of the aluminum electrolytic cell. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-3 As shown, a guide ruler device for an aluminum electrolytic cell includes a moving mechanism and a scraping mechanism. The moving mechanism is movably mounted on a side carbon block 6 of the aluminum electrolytic cell. The upper and side surfaces of the side carbon block 6 are flat. The scraping mechanism includes a vertical arm 1 and a shaped guide ruler 2. The vertical arm 1 is adjustablely mounted on the moving mechanism and is located to the side of the side carbon block 6 of the aluminum electrolytic cell. The shaped guide ruler 2 is fixedly mounted at the bottom of the vertical arm 1 and is located above the inner lining slope 7 of the aluminum electrolytic cell. See also... Figure 3 The side carbon block 6 is located at the left end of the inner lining slope 7, while the right end of the inner lining slope 7 is also a carbon block, which is less than the height of the side carbon block 6.

[0020] The vertical arm 1 is made of a rectangular tube of 50mm×30mm×3mm. The irregular straightedge 2 is made of angle steel of 50mm×3mm. The irregular straightedge 2 is formed according to the shape of the inner lining slope 7 of the corresponding aluminum electrolysis cell.

[0021] The working process of the straightedge device for aluminum electrolysis cells: Carbon paste is applied on the inner lining slope 7 of the aluminum electrolysis cell. The moving mechanism is suspended on the side carbon block 6 of the aluminum electrolysis cell. The position of the vertical arm 1 is adjusted and fixed according to the height of the carbon paste. The position of the irregular straightedge 2 is adjusted. At this time, the irregular straightedge 2 is in contact with the carbon paste. The moving mechanism is horizontally advanced in the extension direction (i.e., the horizontal direction) of the side carbon block 6, thereby driving the vertical arm 1 and the irregular straightedge 2 to advance horizontally. Because the upper surface and side surface of the side carbon block 6 are flat, the irregular straightedge 2 can scrape the carbon paste on the inner lining slope 7 after horizontal advancement. The irregular straightedge 2 accurately scrapes the carbon paste layer, making the overall thickness of the carbon paste layer consistent, and also laying the foundation for the next binding process. The scraped carbon paste layer is then bound. The above process is repeated to achieve multi-layer carbon paste scraping and binding.

[0022] When it is necessary to inspect the flatness of the surface of the carbon paste layer (formed after the carbon paste layer undergoes the binding process) on the inner lining slope 7 of the aluminum electrolytic cell, the moving mechanism is suspended on the side carbon block 6 of the aluminum electrolytic cell. The vertical arm 1 can be adjusted to the correct height and then fixed on the moving mechanism. Afterwards, the appearance quality after the carbon paste is bound can be quickly judged by checking the gap between the irregular straightedge 2 and the surface of the carbon paste layer. If there is no gap, it means that the surface of the carbon paste layer is flat; if there is a gap, it means that the surface of the carbon paste layer is not flat. The gap can be filled with carbon paste to make the surface of the carbon paste layer flat.

[0023] The straightedge device for the aluminum electrolytic cell in this embodiment has a simple structure and is easy to operate. The irregularly shaped straightedge 2 accurately smooths the carbon paste layer, ensuring a consistent overall thickness. When it is necessary to inspect the flatness of the carbon paste layer surface on the inner lining slope 7 of the aluminum electrolytic cell, the appearance quality after the carbon paste is secured can be quickly determined by checking the gap between the irregularly shaped straightedge 2 and the surface of the carbon paste layer, greatly improving the construction quality of the carbon paste on the inner lining slope 7 of the aluminum electrolytic cell. The straightedge device can be reused multiple times.

[0024] In one possible implementation, the moving mechanism includes an inverted L-shaped frame 3, horizontal wheels 4, and vertical wheels 5. The horizontal wheels 4 and vertical wheels 5 are rotatably mounted on the top and side of the inverted L-shaped frame 3, respectively. The horizontal wheels 4 contact and move on the upper surface of the side carbon block 6 of the aluminum electrolysis cell, and the vertical wheels 5 contact and move on the side surface of the side carbon block 6 of the aluminum electrolysis cell. The inverted L-shaped frame 3 is located to the side of the side carbon block 6 of the aluminum electrolysis cell. With the horizontal wheels 4 suspended on the upper surface of the side carbon block 6 of the aluminum electrolysis cell, the entire inverted L-shaped frame 3 is supported by the side carbon block 6 of the aluminum electrolysis cell. Simultaneously, the vertical wheels 5 contact the side surface of the side carbon block 6 of the aluminum electrolysis cell, thus restricting the positions of the vertical arm 1 and the irregular ruler 2. The vertical arm 1 is located to the side of the side carbon block 6 of the aluminum electrolysis cell, and the irregular ruler 2 is located above the inner lining slope 7 of the aluminum electrolysis cell. After the horizontal wheel 4 and the vertical wheel 5 rotate, the horizontal wheel 4 moves relative to the upper surface of the side carbon block 6 of the aluminum electrolysis cell, and the vertical wheel 5 moves relative to the side surface of the side carbon block 6 of the aluminum electrolysis cell. Since the upper surface and side surface of the side carbon block 6 are flat, the inverted L-shaped frame 3 is driven to move horizontally in the extension direction (i.e., the horizontal direction) of the side carbon block 6.

[0025] In one possible implementation, the inverted L-shaped frame 3 includes a wheel rod 31 and a triangular wheel frame 32. The wheel rod 31 is fixedly mounted on top of the triangular wheel frame 32, and the wheel rod 31 and the triangular wheel frame 32 are perpendicular to each other. The wheel rod 31 is located above the side carbon block 6 of the aluminum electrolysis cell, and the two are parallel to each other. A horizontal wheel 4 is provided and rotatably mounted on the wheel rod 31. The triangular wheel frame 32 is located to the side of the side carbon block 6 of the aluminum electrolysis cell, and the two are parallel to each other. Two vertical wheels 5 are provided, and the two vertical wheels 5 are respectively rotatably mounted at both ends of the bottom of the triangular wheel frame 32. The triangular wheel frame 32 is made of a 50mm × 30mm × 3mm rectangular tube, which has the advantage of good stability. Preferably, the wheel rod 31 and the triangular wheel frame 32 can be welded together.

[0026] The horizontal wheel 4 is suspended on the upper surface of the side carbon block 6 of the aluminum electrolysis cell. At this time, the wheel rod 31 and the triangular wheel frame 32 are supported by the side carbon block 6 of the aluminum electrolysis cell, while the two vertical wheels 5 are in contact with the side surface of the side carbon block 6 of the aluminum electrolysis cell. After the horizontal wheel 4 and the two vertical wheels 5 rotate, the horizontal wheel 4 moves relative to the upper surface of the side carbon block 6 of the aluminum electrolysis cell, and the two vertical wheels 5 move relative to the side surface of the side carbon block 6 of the aluminum electrolysis cell, ultimately driving the wheel rod 31 and the triangular wheel frame 32 to move horizontally in the extension direction (i.e., the horizontal direction) of the side carbon block 6.

[0027] Preferably, a first bearing seat is provided on the wheel rod 31, and the axle of the horizontal wheel 4 passes through the first bearing in the first bearing seat and is fixedly connected to it to achieve rotation. Second bearing seats are provided at both ends of the bottom of the triangular wheel frame 32, and the axle of the vertical wheel 5 passes through the second bearing in the second bearing seat and is fixedly connected to it to achieve rotation.

[0028] As one possible implementation, a guide sleeve 33 is fixedly installed on the side of the triangular wheel frame 32 away from the vertical wheel 5. The top of the vertical arm 1 passes through the guide sleeve 33 and is adjustablely mounted on the guide sleeve 33 via a set screw 34. The guide sleeve 33 is made of a 55mm×35mm×5mm rectangular tube to ensure that the vertical arm 1 can be smoothly inserted into it.

[0029] By adjusting the telescopic length of the vertical arm 1 through the guide sleeve 33, i.e., by moving the vertical arm 1 up and down relative to the guide sleeve 33, the position of the vertical arm 1 can be adjusted, thereby adjusting the position of the irregular guide ruler 2, i.e., the irregular guide ruler 2 moves up and down. When the set screw 34 is loosened, the vertical arm 1 moves up and down relative to the guide sleeve 33; when the set screw 34 is tightened, the vertical arm 1 is fixed on the guide sleeve 33.

[0030] After the horizontal wheel 4 and the two vertical wheels 5 rotate, they drive the wheel rod 31 and the triangular wheel frame 32 to move horizontally in the direction of extension of the side carbon block 6 (i.e., the horizontal direction), which in turn drives the vertical arm 1 and the irregular ruler 2 to move horizontally.

[0031] When it is necessary to inspect the flatness of the lining slope 7 of the aluminum electrolytic cell, the horizontal wheel 4 is suspended on the side carbon block 6 of the aluminum electrolytic cell. The vertical arm 1 can be adjusted to the correct height and then fixed on the guide sleeve 33. After that, the appearance quality of the carbon paste after it is fixed can be quickly judged by checking the gap between the irregular ruler 2 and the surface of the lining layer.

[0032] In one possible implementation, the guide sleeve 33 is provided with two screw holes, which are M8 screw holes. Two set screws 34 are provided, and each set screw 34 is a butterfly-shaped set screw. Each set screw 34 passes through a screw hole and is pressed against the top of the vertical arm 1. When the set screw 34 is released, it moves away from the top of the vertical arm 1 and the screw hole, after which the vertical arm 1 moves up and down relative to the guide sleeve 33. When the set screw 34 is locked onto the guide sleeve 33 through the screw hole and pressed against the top of the vertical arm 1, the vertical arm 1 is fixed to the guide sleeve 33.

[0033] As one possible implementation, the vertical arm 1 is provided with scale lines 11. The scale lines 11 facilitate adjustment of the extension and retraction length of the vertical arm 1, thereby facilitating the adjustment of the position of the irregular guide ruler 2. The irregular guide ruler 2 then precisely controls the thickness of each carbon paste layer on the inner lining slope 7 of the aluminum electrolysis cell. According to the required thickness of each carbon paste layer, and following the scale lines 11, the vertical arm 1 moves up and down relative to the guide sleeve 33, thereby causing the irregular guide ruler 2 to move downwards or downwards to adjust its position.

[0034] In one possible implementation, the irregular-shaped ruler 2 includes a first crossbar 21 and a second crossbar 22 fixedly connected. Preferably, the first crossbar 21 and the second crossbar 22 can be welded together, and the included angle formed between the first crossbar 21 and the second crossbar 22 is an obtuse angle. The first crossbar 21 is parallel to the left end of the inner lining slope 7 of the aluminum electrolytic cell, and the second crossbar 22 is parallel to the right end of the inner lining slope 7 of the aluminum electrolytic cell. The first crossbar 21 and the second crossbar 22 are made of 50mm × 3mm angle steel, and their shapes match the inner lining slope 7 of the aluminum electrolytic cell. After the first crossbar 21 and the second crossbar 22 are advanced horizontally, they smooth the carbon paste on the inner lining slope 7, ensuring that the carbon paste layer is precisely smoothed and the overall thickness of the carbon paste layer remains consistent.

[0035] The working process of the straightedge device for the aluminum electrolysis cell: Carbon paste is applied on the inner lining slope 7 of the aluminum electrolysis cell. The horizontal wheel 4 is suspended on the upper surface of the side carbon block 6 of the aluminum electrolysis cell. At this time, the inverted L-shaped frame 3 is supported by the side carbon block 6 of the aluminum electrolysis cell, and the two vertical wheels 5 are in contact with the side surface of the side carbon block 6 of the aluminum electrolysis cell. According to the height of the carbon paste, the set screw 34 is loosened, the extension length of the vertical arm 1 is adjusted appropriately, and then the set screw 34 is tightened. The position of the irregular straightedge 2 is adjusted, and at this time the irregular straightedge 2 is in contact with the carbon paste. After the horizontal wheel 4 and the two vertical wheels 5 rotate, the horizontal wheel 4 moves relative to the upper surface of the side carbon block 6 of the aluminum electrolysis cell, and the two vertical wheels 5 move relative to the side surface of the side carbon block 6 of the aluminum electrolysis cell. Since the upper surface and side surface of the side carbon block 6 are flat, the inverted L-shaped frame 3, the vertical arm 1 and the irregular straightedge 2 are driven to move horizontally in the extension direction (i.e., the horizontal direction) of the side carbon block 6. After the irregular straightedge 2 moves horizontally, it scrapes the carbon paste on the inner lining slope 7.

[0036] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification.
