Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum, in particular to a tool for measuring the pole distance of an electrolytic cell. Background Art

[0002] During the electrolysis of aluminum, electrolyte is added above the cathode carbon block and the anode carbon block is immersed in the electrolyte. The anode carbon block and the cathode carbon block are not in direct contact, and the distance between the anode carbon block and the cathode carbon block is the pole distance. In the electrolysis process, the anode carbon block is continuously consumed, and the anode carbon block needs to be continuously lowered to prevent the anode carbon block from leaving the electrolyte due to consumption. Because the cathode carbon block is inside the electrolytic cell, it cannot be directly observed and measured. When entering the surface of the cathode carbon block, the interior of the electrolytic cell is an inclined surface, and it is necessary to pass through the inclined surface before measurement. In the prior art, a measuring ruler with multiple bending sections is used for measurement. If the measuring ruler is directly placed in, the measuring section of the measuring ruler is easy to collide with the anode carbon block, affecting the electrolysis efficiency. The measuring ruler can only be reversed and placed in, and then reversed and straightened when it contacts the surface of the cathode carbon block. This method is not convenient for straightening during the reversal process. When the measuring ruler and the cathode carbon block are not parallel, it has a greater impact on the measured data. Utility Model Content

[0003] In view of the technical problems existing in the background technology, the purpose of the utility model is to provide an electrolytic cell inter-electrode distance measuring tool, which can be folded into multiple sections, slowly unfolded during the process of being placed in the electrolytic cell, and can be placed in the electrolytic cell without reversing, thereby increasing the measurement accuracy.

[0004] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0005] A tool for measuring the distance between the electrodes of an electrolytic cell comprises a measuring ruler arranged between a cathode carbon block and an anode carbon block, the measuring ruler comprises a support plate and a connecting plate slidably connected to the support plate, the connecting plate is provided with a measuring plate for measuring the distance between the cathode carbon block and the anode carbon block, one end of the support plate is provided with a stopper parallel to the cathode carbon block, the connecting plate can slide along the direction of the support plate and collide with the stopper, so that the connecting plate rotates to a parallel position.

[0006] Preferably, an opening is provided through the connecting plate.

[0007] Preferably, the measuring plate is rotatably arranged in the opening, and a return spring is arranged at the position where the measuring plate and the connecting plate are rotatably connected.

[0008] Preferably, a limit block for limiting the rotation of the measuring plate is vertically arranged at one end of the connecting plate.

[0009] Preferably, slide grooves are provided on both sides of the support plate.

[0010] Preferably, a sliding rod is provided at one end of the connecting plate, and the sliding rod is slidably connected in the sliding groove.

[0011] Preferably, when the connecting plate and the cathode carbon block are parallel, the limiting block and the stopper are respectively supported on the surface of the cathode carbon block.

[0012] The utility model has the following advantages and beneficial effects:

[0013] 1. In the utility model, the support plate is placed on an inclined plane to prevent the measuring tool from shaking during the measurement process, which may cause errors in the measured data. The connecting plate slides along the direction of the support plate and falls into the surface position of the cathode carbon block. When falling, it collides with the stopper, and the stopper causes the connecting plate to rotate and be parallel to the cathode carbon block. The position can be found without manual adjustment, which is convenient for measuring the pole distance.

[0014] 2. In the utility model, the measuring plate can be folded and inserted into the connecting plate, and a reset spring is provided at the rotational connection between the measuring plate and the connecting plate. When the connecting plate slides on the supporting plate, the reset spring drives the measuring plate to rotate and finally is in a perpendicular position to the connecting plate, thereby avoiding the risk of collision between the measuring tools when they are directly inserted into the electrolytic cell.

[0015] 3. The utility model has a simple structure, is easy to operate, and is convenient for measuring the pole distance. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example

[0028] like Figure 1-4 As shown, a tool for measuring the inter-electrode distance of an electrolytic cell includes a measuring ruler arranged between a cathode carbon block 101 and an anode carbon block 102, the measuring ruler includes a support plate 2 and a connecting plate 3 slidably connected to the support plate 2, the support plate 2 is bent at a certain angle, when the support plate 2 is placed above the electrolytic cell 1, one end of the support plate 2 extends into the electrolytic cell 1 and fits with the inclined surface inside the electrolytic cell 1, and the inclined surface is used as a support point for measurement, thereby preventing the measuring ruler from being deflected inside the electrolytic cell 1 and causing inaccurate measurement results.

[0029] like Figure 1-8 As shown, slide grooves 21 are provided on both sides of the support plate 2, and the slide grooves 21 are provided on a section of the support plate 2 extending into the electrolytic cell 1. A slide rod 32 is provided at one end of the connecting plate 3, and the slide rod 32 can be slidably connected in the slide groove 21. A stopper 22 parallel to the cathode carbon block 101 is provided at one end of the support plate 2. The connecting plate 3 can slide along the direction of the support plate 2 and collide with the stopper 22, so that the connecting plate 3 rotates to a parallel position. At the same time, the lower end of the stopper 22 can also be placed on the surface of the cathode carbon block 101 to support the measuring ruler.

[0030] like Figure 1 , 5As shown in Figures 6, 7 and 8, the other end of the connecting plate 3 is provided with a through opening 31, and a measuring plate 4 for measuring the distance between the cathode carbon block 101 and the anode carbon block 102 is provided in the opening 31, and the measuring plate 4 and the connecting plate 3 are rotatably connected, and the measuring plate 4 can be rotatably stored in the opening 31. A reset spring 41 is also provided at the connection position between the measuring plate 4 and the connecting plate 3, and the reset spring 41 drives the measuring plate 4 to rotate. When the measuring plate 4 is in the opening 31, the reset spring 41 drives the measuring plate 4 to rotate out of the opening 31, so that the angle between the measuring plate 4 and the connecting plate 3 gradually increases.

[0031] like Figure 1-8 As shown, a limit block 33 for limiting the rotation of the measuring plate 4 is vertically arranged at one end of the connecting plate 3, and the limit block 33 is arranged on the outside of the opening 31. When the angle between the measuring plate 4 and the connecting plate 3 gradually increases so that they are perpendicular to each other, the measuring plate 4 and the limit block 33 contact, and the limit block 33 supports the measuring plate 4 and keeps it in a vertical position to facilitate the measurement of the distance between the poles. At the same time, when the connecting plate 3 and the cathode carbon block 101 are parallel, the bottom of the limit block 33 is also placed on the surface of the cathode carbon block 101, and supports the measuring ruler together with the stop block 22.

[0032] Working principle: When the inter-electrode distance needs to be measured, first pull the connecting plate 3 back to the bending position of the supporting plate 2 and rotate it toward the bending position, and at the same time press the measuring ruler into the opening 31, so that most of the structure of the longer measuring ruler can be folded, which is convenient for inserting into the electrolytic cell 1 to prevent collision with the anode carbon block 102, and then extend the supporting plate 2 into the electrolytic cell 1 and cling to the inclined surface. At this time, the block 22 is supported on the surface of the cathode carbon block 101, and the connecting plate 3 is loosened, and the connecting plate 3 slides into the electrolytic cell 1. When the connecting plate 3 slides to the bottom of the supporting plate 2, it collides with the block 22, and the block 22 restricts the connecting plate 3 from continuing to slide, and at the same time, the connecting plate 3 The plate 3 rotates to a position parallel to the cathode carbon block 101. At this time, the stop block 22 contacts the surface of the cathode carbon block 101 to support the measuring ruler. During the sliding of the connecting plate 3, the reset spring 41 continuously rebounds, causing the measuring plate 4 to rotate out of the opening 31. The measuring plate 4 rotates out of the opening 31 and abuts against the supporting plate 2, causing the connecting plate 3 to gradually move away from the supporting plate 2; until the connecting plate 3 flips over to be parallel to the cathode carbon block 101, the measuring plate 4 rotates to a position perpendicular to the connecting plate 3, and contacts the limit block 33. The limit block 33 keeps it in a vertical position, so that the distance between the poles can be directly measured, which is convenient for workers to measure.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
