Description

Technical Field

[0001] This utility model belongs to the field of electrolytic cell measurement technology, and specifically relates to a measuring tool for the furnace side of an aluminum electrolytic cell. Background Technology

[0002] In aluminum production, the aluminum electrolytic cell is one of the core pieces of equipment, and its operating efficiency and stability directly affect the yield and quality of aluminum. The furnace lining, as part of the electrolytic cell's inner lining, not only withstands the erosion of high-temperature molten aluminum and electrolytes but also directly affects the cell's thermal balance and current efficiency. Therefore, accurate measurement of the aluminum electrolytic cell furnace lining is crucial for ensuring long-term stable operation, optimizing production parameters, and improving economic efficiency. Existing measurement methods can only achieve single-point measurements after the measuring end enters the cell. When performing multi-point measurements, the lack of a guiding structure during the up-and-down movement along the furnace lining leads to inaccurate results.

[0003] Therefore, in order to address the above-mentioned technical problems, the design of a furnace side measuring tool for aluminum electrolysis cells is necessary. Ensuring the accuracy of the measurement results while ensuring that the measuring tool can measure the furnace side at multiple points for a long time after entering the aluminum electrolysis cell is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a furnace side measuring tool for aluminum electrolysis cells. This tool ensures the accuracy of the measurement results while allowing for prolonged and multi-point measurements of the furnace side after entering the aluminum electrolysis cell.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A measuring tool for the furnace side of an aluminum electrolytic cell includes a handheld part with scale lines, a groove insertion part disposed at the end of the handheld part, and a movable scale sleeved on the handheld part and movable along the handheld part in both the lateral and longitudinal directions.

[0007] Preferably, the handle has a first elongated through hole for the movable ruler to move laterally along the handle, and the end of the handle away from the groove has an opening communicating with the first elongated through hole. The movable ruler is a plate-shaped structure, and the plate-shaped structure has a second elongated through hole for passing through the opening and fitting onto the handle.

[0008] Preferably, the width of the second elongated through hole is not less than the thickness of the hand grip portion that mates with the second elongated through hole.

[0009] Preferably, the groove portion includes a vertical rod disposed at the end of the handle portion, and a horizontal rod perpendicular to the vertical rod and extending toward the end of the movable ruler.

[0010] Preferably, the length of the horizontal rod along the extension direction toward the movable scale end is the same as the length from the 0 mark line on the scale line to the vertical rod, and the 0 mark line is set on the side closer to the vertical rod.

[0011] Preferably, a hand ring is provided at one end of the hand-held part away from the groove part.

[0012] Preferably, the bottom of the movable ruler is provided with a fixing device for fixing to the edge plate of the aluminum electrolysis cell.

[0013] Preferably, the fixing device is a first suction cup or a first adhesive layer that is detachable and disposed at the bottom of the movable ruler.

[0014] Preferably, the movable scale is provided with a suction device on the contact surface between it and the inner channel steel of the aluminum electrolysis cell to attract the inner channel steel.

[0015] Preferably, the suction device is a second suction cup or a second adhesive layer that is disposed on the movable ruler and is removable.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] When measuring the furnace wall thickness, the inlet part is inserted into the aluminum electrolysis cell. The bottom surface of the movable ruler abuts against the edge plate of the aluminum electrolysis cell, and the end face of the movable ruler near the inlet part abuts against the inner channel steel of the aluminum electrolysis cell. The inlet part abuts against the inner wall of the furnace wall. At this time, because the bottom and end faces of the movable ruler are abutted by the edge plate and the inner channel steel respectively, they can act as guide components. When it is necessary to measure the furnace wall thickness at different locations in the aluminum electrolysis cell, it is only necessary to move the hand-held part along the longitudinal direction of the movable ruler to achieve multi-point measurement of the furnace wall in the aluminum electrolysis cell. Moreover, due to the guidance of the movable ruler, it can be ensured that the hand-held part will not be deflected during the movement, thus ensuring the accuracy of the measurement.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this invention is to provide a measuring tool for the furnace side of an aluminum electrolytic cell, which ensures the accuracy of the measurement results while allowing for long-term, multi-point measurement of the furnace side after the measuring tool enters the aluminum electrolytic cell.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] refer to Figures 1-4The aluminum electrolytic cell furnace side measuring tool disclosed in this embodiment of the present invention includes at least a handheld part 1 with scale lines 5. The end of the handheld part 1 has an insertion part that extends into the aluminum electrolytic cell 10. A movable scale 2 is also fitted onto the handheld part 1. The movable scale 2 can move laterally and longitudinally along the handheld part 1. When measuring the thickness of the furnace side 9, the insertion part is inserted into the aluminum electrolytic cell 10, and the bottom surface of the movable scale 2 abuts against the edge plate 8 of the aluminum electrolytic cell 10. The end face of the movable scale 2 near the insertion part is in contact with the aluminum electrolytic cell 10. The inner channel steel 7 abuts against the groove, and the groove part abuts against the inner wall of the furnace side 9. At this time, because the bottom surface and end surface of the movable scale 2 are abutted by the groove edge plate 8 and the inner channel steel 7 respectively, it can be used as a guide component. When it is necessary to measure the thickness of the furnace side 9 at different positions in the aluminum electrolysis cell 10, it is only necessary to move the hand part 1 along the longitudinal direction of the movable scale 2 to realize multi-point measurement of the furnace side 9 in the aluminum electrolysis cell 10. Moreover, due to the guidance of the movable scale 2, it can be ensured that the hand part 1 will not be deflected during the movement, thus ensuring the accuracy of the measurement.

[0028] refer to Figures 1-3 In one embodiment, the handheld part 1 has a first elongated through hole for the movable ruler 2 to move laterally along the handheld part 1. The end of the handheld part 1 away from the groove has an opening that communicates with the first elongated through hole. That is, the handheld part 1 is formed by two straight plates attached together, and there is a gap between the two straight plates to form the first elongated through hole. The movable ruler 2 is a plate-like structure with a second elongated through hole for passing through the opening and fitted onto one of the straight plates of the handheld part 1. By setting the first elongated through hole, the movable ruler 2 can move laterally along the handheld part 1. By setting the second elongated through hole and fitting the second elongated through hole onto one of the straight plates of the first elongated through hole, the movable ruler 2 can move longitudinally along the handheld part 1. That is, the handheld part 1 can also move relatively along the lateral and longitudinal directions of the movable ruler 2.

[0029] It should be noted that the handle 1 can also be made of two iron bars joined together, with the gap in the middle allowing the movable ruler 2 to move horizontally and vertically. The scale line 5 on the handle 1 can also be achieved by directly fixing a steel ruler. The movable ruler 2 can also be a folded aluminum sheet, with one side inserted into the gap between the two iron bars of the handle 1 and the other side close to the steel ruler as a reading reference.

[0030] refer to Figure 1 In one embodiment, the width of the second elongated through hole is not less than the thickness of the straight plate on the handheld part 1 that mates with the second elongated through hole. This ensures that when the handheld part 1 moves laterally and longitudinally within the second elongated through hole, the second elongated through hole can guide the handheld part 1, preventing the handheld part 1 from tilting during movement and thus ensuring measurement accuracy.

[0031] refer to Figure 1 and Figure 2 In one embodiment, the inlet section includes a vertical rod 3 provided on the handheld part 1 and a horizontal rod 6 perpendicular to the vertical rod 3. The horizontal rod 6 extends along the direction of the movable scale 2. By providing the vertical rod 3, the height of the inlet section extending into the aluminum electrolysis cell 10 can be guaranteed. By providing the horizontal rod 6, the measurement accuracy can be guaranteed when performing multi-point measurements (because the furnace side 9 of the aluminum electrolysis cell 10 is not a smooth surface, but an uneven surface. If the horizontal rod 6 is not provided, after the vertical rod 3 is inserted, it will be in contact with the surface of the furnace side 9, and only the thickness of the highest protruding part of the furnace side 9 can be measured. However, after providing the horizontal rod 6, point contact measurement of the surface of the furnace side 9 can be achieved. When performing multi-point measurement of the furnace side 9 in the aluminum electrolysis cell 10, the thickness of different surfaces of the furnace side 9 can be measured, ensuring the measurement accuracy).

[0032] refer to Figure 1 In one implementation, the length of the horizontal rod 6 along the extension direction toward the end of the movable scale 2 is consistent with the length from the 0 mark line on the scale line 5 to the vertical rod 3. The 0 mark line is set on the side closer to the vertical rod 3. By making the length of the horizontal rod 6 consistent with the length from the 0 mark line to the vertical rod 3, the thickness of the furnace side 9 can be determined by reading directly without calculation.

[0033] refer to Figure 1 As one implementation, a hand ring 4 is provided on the end of the hand-held part 1 away from the groove, which makes it convenient for the operator to pick up and hold.

[0034] refer to Figure 1 In one embodiment, the bottom of the movable ruler 2 is provided with a fixing device for fixing to the groove edge plate 8 on the aluminum electrolysis tank 10. By setting the fixing device, the bottom of the movable ruler 2 can be fixed to the groove edge plate 8, thereby supporting the movable ruler 2 and improving the guiding effect of the movable ruler 2 on the hand-held part 1.

[0035] refer to Figure 1 In one embodiment, the fixing device is a first suction cup or a first adhesive layer that is detachable and set at the bottom of the movable ruler 2. By setting the first suction cup and the first adhesive layer, the bottom of the movable ruler 2 can be fixed on the groove edge plate 8. The first suction cup and the first adhesive layer are detachable, which can avoid the failure of adsorption or bonding effect after the dust is stuck.

[0036] refer to Figure 1 and Figure 2In one embodiment, a suction device is provided on the contact surface between the movable ruler 2 and the inner channel steel 7 of the aluminum electrolysis cell 10 to attract the inner channel steel 7. By setting the suction device, the bottom of the movable ruler 2 can be attracted to the inner channel steel 7, thereby fixing the movable ruler 2 and improving the guiding effect of the movable ruler 2 on the hand part 1.

[0037] refer to Figure 1 In one embodiment, the suction device is a second suction cup and a second adhesive layer that are detachable and mounted on the movable ruler 2. By setting the second suction cup and the second adhesive layer, the movable ruler 2 can be fixed on the inner channel steel 7. Furthermore, by detaching the second suction cup and the second adhesive layer, the adsorption or bonding effect can be prevented from failing after the ash is adhered.

[0038] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0039] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
