[0027] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0028] Embodiment one

[0029] The present embodiment provides a laser emitter correction device, as shown inFigures 1-3 As shown, it comprises a horizontal bottom rod 4, a vertical rod 1, a steel ruler 5 and a level instrument; the lower end of the vertical rod 1 is fixedly connected with the horizontal bottom rod 4, and the horizontal bottom rod 4 is arranged at 90° with the vertical rod 1; the steel ruler 5 is fixedly arranged on the vertical rod 1 in a vertical manner; the steel ruler 5 is provided with a scale; and the level instrument is fixedly arranged on the horizontal bottom rod 4 and can measure the level of the horizontal bottom rod 4.

[0030] The level of the entire device is adjusted by the level instrument on the horizontal bottom rod 4, and when the level instrument shows that the horizontal bottom rod 4 is in a horizontal position, the verticality of the vertical rod 1 can be ensured at this time, which provides a stable horizontal reference for subsequent correction work and reduces the deviation in the vertical direction. The setting of the steel ruler 5 can provide a precise laser landing point determination standard for the laser emitter; and the standard steel ruler 5 is directly fixed on the vertical rod 1, which has higher precision than the scale plate manually drawn in the prior art and can reduce the error caused by manual drawing; and the overall structure is simple and convenient, portable and high in flexibility; the steel ruler 5 is fixed on the vertical rod 1 in a detachable manner (including but not limited to riveting and the like), which facilitates the maintenance and replacement of the steel ruler 5.

[0031] Among them, the related setting between the horizontal bottom rod 4 and the vertical rod 1 is as follows:

[0032] In the optional solution of the embodiment, preferably, as shown in Figure 1 The horizontal bottom rod 4 and the vertical rod 1 are further provided with a connecting reinforcing inclined rod 3; one end of the connecting reinforcing inclined rod 3 is fixedly connected with the horizontal bottom rod 4, and the other end of the connecting reinforcing inclined rod 3 is fixedly connected with the vertical rod 1. After the connecting reinforcing inclined rod 3 is arranged between the horizontal bottom rod 4 and the vertical rod 1, a triangular structure is formed. The triangular structure has stability in mechanics and can effectively resist the interference of external factors on the device; since the connecting reinforcing inclined rod 3 enhances the stability of the device, more accurate results can be obtained when the steel ruler 5 is used for vertical direction measurement and the level instrument is used for horizontal measurement.

[0033] In the optional solution of the embodiment, preferably, as shown in Figure 1 The horizontal bottom rod 4 and the vertical rod 1 are in an L shape. The structure design of the horizontal bottom rod 4 and the vertical rod 1 in an L shape is very intuitive and convenient for users to understand and operate.

[0034] Among them, the related setting of the level instrument is as follows:

[0035] In the optional solution of the embodiment, preferably, the level instrument has a level tube arranged horizontally, and the level tube is filled with liquid and a bubble. The design of filling the level tube with liquid and a bubble can achieve high-precision level measurement. When the cross bottom rod 4 is in a completely horizontal state, the bubble will be exactly located at the center position of the level tube. This detection method based on the horizontal characteristics of the liquid surface is very sensitive and can detect slight tilting.

[0036] In the optional solution of the embodiment, preferably, as shown in Figure 1 The level instrument is a level ruler 2. The level ruler 2 is a relatively simple and easy-to-use tool. It usually has clear scales and intuitive level indications. When using the laser emitter correction device, the technician can quickly determine whether the cross bottom rod 4 is horizontal by observing the bubble or the scale on the level ruler 2. This convenience makes the correction process more efficient and easy to use without complex operation steps or professional training. The level ruler 2 is a very versatile tool that is commonly available.

[0037] Usage: When in use, place the height measuring system at an appropriate height, fix the laser emitter on it, place the laser emitter correction device of the embodiment in front of the laser emitter 1 m away, determine the levelness of the cross bottom rod 4 through the level ruler 2, observe the landing scale of the laser emitted by the laser emitter on the steel ruler 5, move the laser emitter correction device of the embodiment to the far end, and the landing point of the laser emitted by the laser emitter on the steel ruler 5 does not change under the condition that the levelness of the level ruler 2 does not change, then the angle of the height measuring laser emitter does not need to be adjusted; if the landing point of the laser emitted by the laser emitter on the steel ruler 5 changes, the angle of the height measuring laser emitter needs to be adjusted correspondingly.

[0038] The laser emitter correction device of the embodiment has a simple overall structure, is easy to carry, and can be reused. It can unify the correction standard and use existing standard steel rulers 5 and level rulers 2, so it has higher precision.

[0039] In the process of aluminum electrolysis production, anode height measurement is a crucial step. The distance between the anode and the electrolyte surface directly affects the electrolysis efficiency and the quality of aluminum. Therefore, the laser emitter correction device emerges as the times require. We need to clarify the basic functions of the laser emitter correction device. This device corrects the laser emitter to accurately measure the distance between the anode and the electrolyte surface to ensure that the distance between them is constant. This function itself brings several significant advantages.

[0040] Advantage one: improve production efficiency, aluminum electrolysis is a continuous production process, the small changes in anode height can affect the electrolysis efficiency. The laser emitter correction device can quickly adjust the laser emitter to the best position through accurate adjustment, thereby ensuring the continuity and stability of the electrolysis anode changing operation.

[0041] Advantage two: ensure the quality of aluminum, the distance between the anode and the electrolyte surface has a direct impact on the quality of aluminum. If the distance is too large or too small, it will lead to uneven current distribution in the electrolysis process, thereby affecting the purity and uniformity of aluminum. The laser emitter correction device can accurately place the anode by accurately correcting the laser emitter, thereby ensuring the uniform distribution of current in the electrolytic cell, thereby producing stable quality aluminum products.

[0042] Advantage three: reduce energy consumption, in the aluminum electrolysis process, energy consumption is an important cost factor. Changes in anode height will cause changes in the resistance of the electrolytic cell, thereby affecting energy consumption. The laser emitter correction device can keep the constant distance between the anode and the electrolyte surface after the anode changing operation by accurately correcting the laser emitter, thereby ensuring the stability of the resistance in the electrolytic cell, thereby reducing energy consumption.

[0043] Advantage four: reduce manual intervention, the traditional anode height measurement laser emitter adjustment method has too many human factors, which is easy to introduce human error.

[0044] Advantage five: improve safety, the device is light, the correction time is short, reduces the working time, and the tools are convenient to carry, at the same time, the safety is guaranteed to the greatest extent.

[0045] In summary, the laser emitter correction device brings multiple advantages such as improving production efficiency, ensuring the quality of aluminum, reducing energy consumption, reducing manual intervention and improving safety by accurately adjusting the laser emitter. These advantages not only improve the overall efficiency of aluminum electrolysis production, but also provide strong support for the sustainable development of enterprises.
