Abstract
Description
Technical Field
[0001] The utility model relates to a device for measuring the consumption of prebaked anodes of an aluminum electrolytic cell, belonging to the field of anode consumption measuring tools. Background Art
[0002] In the production process of electrolytic aluminum, the anode of the electrolytic cell participates in the electrochemical reaction of generating aluminum liquid, and oxidizes at a high temperature of about 960 degrees, causing carbon particles to fall off and enter the electrolyte to form carbon slag. Excessive carbon slag will have an adverse effect on production, which is manifested in increased voltage drop of the electrolyte, increased cell temperature, increased secondary reaction of aluminum in the electrolytic cell, decreased current efficiency, and increased burst effect.
[0003] Therefore, in order to study the impact of anode consumption on the production process during aluminum electrolysis, it is necessary to collect data on the used anodes. That is, a prebaked anode consumption measurement device for aluminum electrolysis cells is needed, which can measure the consumption data of prebaked anodes. Utility Model Content
[0004] In view of this, the purpose of the utility model is to provide a device for measuring the consumption of prebaked anodes in an aluminum electrolytic cell, which can overcome the shortcomings of the prior art.
[0005] The purpose of this utility model is achieved through the following technical solutions:
[0006] The utility model discloses a device for measuring the consumption of prebaked anodes of an aluminum electrolytic cell, which is used for measuring the prebaked anodes taken out of the electrolytic cell, and comprises a main scale, a fixed external measurement claw A is arranged at the lower end of the main scale, and an external measurement claw B which can move along the main scale is arranged on the main scale, the suspended end of the external measurement claw B is used for measuring the middle part of the carbon block of the prebaked anode, and a level ruler is arranged on the main scale.
[0007] The above-mentioned level ruler is provided with a vertical vial bubble and a horizontal vial bubble.
[0008] As mentioned above, the measuring claw B for external measurement is a horizontal plate.
[0009] As mentioned above, the external measurement claw B is an arc-shaped plate with an opening facing downward, and the lower surface of the suspended end of the arc-shaped plate is level with the lower surface of the fixed end.
[0010] As mentioned above, a slider is provided on the main scale, and the measuring claw B for external measurement is fixed on the slider.
[0011] As mentioned above, the device also includes a heat insulation plate, which includes a base, a vertical baffle located on the base, and an upper baffle located on the vertical baffle and inclined outward, and a vertical measuring channel and a horizontal measuring channel for the main ruler to enter and exit are provided on the vertical baffle.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The utility model positions the external measurement claw A at the bottom of the prebaked anode, adjusts the main scale horizontally and vertically by a level ruler, and then moves the external measurement claw B to the measuring point to obtain the prebaked anode data after measurement, and then compares the data with the new anode data to obtain the consumption data. At the same time, the device can measure the loss of the prebaked anode height, length and width, which is conducive to understanding and collecting the anode loss data.
[0014] 2. The level ruler is provided with a vertical level bubble and a horizontal level bubble. During the measurement process, because the bottom of the anode may be uneven after use, the vertical level bubble and the horizontal level bubble cooperate with each other to adjust the verticality of the main ruler, and ensure that the external measurement claw B, which is perpendicular to the main ruler, moves to accurately measure the data of the prebaked anode.
[0015] 3. The difference between this embodiment and the embodiment is that the shape of the measuring claw B for external measurement is different. The second scheme of the measuring claw B for external measurement is an arc-shaped plate with an opening facing downward. The lower surface of the suspended end of the arc-shaped plate is level with the lower surface of the fixed end. Because the surface of the anode after use is prone to unevenness, when measuring, the measuring point is the steel claw in the middle of the carbon block. Therefore, there may be a bulge between the middle of the carbon block and the upper surface of the side of the carbon block. The arc-shaped plate can cross the bulge, so that the point in the middle of the carbon block can be measured, reducing the work of leveling the upper surface of the carbon block before measurement.
[0016] 4. The heat insulation board includes a base, a vertical baffle board located on the base, and an upper baffle board located on the vertical baffle board and inclined outward. A vertical measuring channel and a horizontal measuring channel for the main ruler to enter and exit are provided on the vertical baffle board. Because the temperature of the prebaked anode is relatively high after it is taken out of the electrolytic cell, the heat insulation board can be used for heat insulation during measurement, and the vertical measuring channel and the horizontal measuring channel can facilitate the measurement of the prebaked anode and the acquisition of data.

DETAILED DESCRIPTION
[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.
[0026] Example 1
[0027] like Figure 1-Figure 3As shown, the utility model discloses a device for measuring the consumption of prebaked anodes of an aluminum electrolytic cell, which is used to measure the prebaked anode 1 taken out of the electrolytic cell, and comprises a main scale 2, a fixed external measurement claw A3 is provided at the lower end of the main scale 2, a external measurement claw B4 which can move along the main scale 2 is provided on the main scale 2, a slider 9 is provided on the main scale 2, the external measurement claw B4 is fixed on the slider 9, the suspended end of the external measurement claw B4 is used to measure the middle part of the carbon block 5 of the prebaked anode 1, and a horizontal scale 6 is provided on the main scale 2. With such a structure, when measuring, the external measurement claw A3 is positioned at the bottom of the prebaked anode 1, and the main scale 2 is adjusted horizontally and vertically by the horizontal scale 6, and then the external measurement claw B4 is moved to the measuring point to obtain the measured data of the prebaked anode 1, and then the data is compared with the new anode data to obtain the consumption data. At the same time, the device can measure the loss of the height, length and width of the prebaked anode 1, which is conducive to understanding and collecting the data of anode loss. Furthermore, a vertical level bubble 7 and a horizontal level bubble 8 are provided on the level ruler 6. During the measurement process, since the bottom of the anode after use may be uneven, the vertical level bubble 7 and the horizontal level bubble 8 cooperate with each other to adjust the main ruler 2 vertically, ensuring that after the external measurement claw B4 perpendicular to the main ruler 2 is moved, the data of the prebaked anode 1 can be accurately measured.
[0028] Specifically, the second solution of the external measurement claw B4 is a horizontal plate, so that the data of the prebaked anode 1 can be measured by moving the horizontal plate.
[0029] Example 2
[0030] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the shape of the measuring claw B4 for external measurement is different. The second scheme of the measuring claw B4 for external measurement is an arc-shaped plate with an opening facing downward, and the lower surface of the suspended end of the arc-shaped plate is level with the lower surface of the fixed end. Because the surface of the anode after use is prone to unevenness, when measuring, the measuring point is the steel claw in the middle of the carbon block 5. Therefore, there may be a bulge between the middle of the carbon block 5 and the upper surface of the side of the carbon block 5. The arc-shaped plate can cross the bulge, so that the point in the middle of the carbon block 5 can be measured, reducing the work of leveling the upper surface of the carbon block 5 before measurement.
[0031] Example 3
[0032] like Figure 5As shown, this embodiment adds a heat insulation board 10 on the basis of embodiment 1 or 2. Specifically, the heat insulation board 10 includes a base 11, a vertical baffle 12 located on the base 11, and an upper baffle 13 located on the vertical baffle 12 and inclined outward. A vertical measuring channel 14 and a horizontal measuring channel 15 for the main scale 2 to enter and exit are provided on the vertical baffle 12. Because the temperature of the prebaked anode 1 is relatively high after it is taken out of the electrolytic cell, the heat insulation board 10 can be used for insulation during measurement, and the vertical measuring channel 14 and the horizontal measuring channel 15 can facilitate the measurement of the prebaked anode 1 and the acquisition of data.
[0033] The above is only a preferred embodiment of the utility model, and does not limit the confidentiality of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still falls within the scope of the technical solution of the utility model.
