Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of molten aluminum monitoring, especially to a laser phase range finding device for real-time molten aluminum level monitoring under high temperature environment. BACKGROUND

[0002] In the industry of molten aluminum production and processing, real-time and accurate monitoring of molten aluminum level is crucial for production process control and quality assurance. High temperature environment is a typical scenario for molten aluminum, which brings great challenges to level monitoring. Traditional level monitoring methods often have many limitations in high temperature environment, and cannot meet the requirements of high precision, real-time and stability. With the development of laser technology, laser phase range finding device gradually becomes an effective means for molten aluminum level monitoring in high temperature environment due to its high precision, non-contact measurement and other advantages. However, high temperature environment not only affects the propagation characteristics of laser, but also causes damage to electronic components and optical components of range finding device, reducing its performance and service life. Therefore, a specially designed device is needed to ensure that the laser phase range finding device can work stably and accurately in high temperature environment, and realize reliable monitoring of molten aluminum level.

[0003] The existing devices for monitoring the level of molten aluminum in high temperature environment have various forms in mechanical structure and technical principle. Some traditional devices adopt simple heat insulation structure, such as wrapping a layer of heat insulation material outside the range finding device, but the heat insulation effect of this way is limited, and it is difficult to effectively block the conduction of high temperature. In terms of heat dissipation, some devices adopt natural heat dissipation or simple fan heat dissipation. Natural heat dissipation is inefficient, and it is difficult to meet the demand of rapid heat dissipation in high temperature environment. Simple fan heat dissipation has problems such as uneven air flow and incomplete heat dissipation. In terms of impurity protection, some devices have no special filtering measures, or use simple filtering methods such as simple filter screen, which has poor filtering effect and is easy to be blocked by dust and other impurities, and is not easy to clean and replace. These devices do not fully consider the comprehensive influence of high temperature environment on various components in terms of technical principle, and lack systematic design to cope with the challenges of high temperature, impurities and other aspects.

[0004] The prior art has a prominent problem in monitoring the liquid level of molten aluminum in a high-temperature environment, which is that the protection of the distance measuring device is insufficient, and it cannot effectively cope with the damage of the high-temperature environment to the distance measuring device. Specifically, in a high-temperature environment, the distance measuring device is easily affected by high temperature, causing the internal components to degrade in performance or even be damaged. For example, high temperature can cause the operating temperature of electronic components to exceed the normal range, affecting their electrical performance and stability and shortening their service life. For optical components, high temperature causes deformation of the material or changes in optical performance, thereby affecting the emission and reception accuracy of the laser. Moreover, impurities such as dust from the outside can easily enter the device, further interfering with the normal operation of the distance measuring device and affecting the accuracy and reliability of the liquid level monitoring. However, existing devices often lack effective temperature isolation, heat dissipation, and impurity filtration measures, or these measures are not perfect enough to effectively address the impact of high temperature and impurities on the distance measuring device, thereby failing to ensure the stable operation and accurate measurement of the distance measuring device in a high-temperature environment. Therefore, a laser phase distance measuring device for real-time monitoring of the liquid level of molten aluminum in a high-temperature environment is proposed to solve the above problems.

DETAILED DESCRIPTION

[0032] The technical scheme in the utility model embodiments will be described clearly and completely below in conjunction with the drawings in the utility model embodiments, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0033] Refer to Figure 1 - Figure 3The utility model provides a kind of embodiment of the utility model provides a kind of laser phase range finder of high-temperature environment under liquid level monitoring of aluminium liquid real-time, including range finder 7, range finder 7 outer wall is provided with temperature insulation box 1, temperature insulation box 1 uses double-layer stainless steel plate structure, middle fills high-quality heat insulation rock wool, this structure can effectively block high temperature to internal conduction, for range finder 7 provide good heat insulation protection, temperature insulation box 1 outer wall is fixedly connected with support 4, support 4 is made of high-strength alloy steel, with good load capacity and stability, can ensure that the whole device is placed safely above high-temperature aluminium liquid, temperature insulation box 1 both sides are provided with heat dissipation component, temperature insulation box 1 outer wall is rotatably connected with protective door 3, temperature insulation box 1 inside is provided with calibration component, calibration component acts on range finder 7 and is calibrated, temperature insulation box 1 inside is provided with fixed component;

[0034] Heat dissipation component includes protective housing 5, protective housing 5 outer wall is fixedly connected in temperature insulation box 1 outer wall, protective housing 5 inside is set with heat dissipation hole 23, protective housing 5 inside is provided with fan 6, temperature insulation box 1 inside is set with clamping groove 9, temperature insulation box 1 inside is provided with filter plate 10, filter plate 10 adopts multilayer structure, outer layer is stainless steel net, middle is clamped with activated carbon filter layer, can effectively filter dust and impurity in air, filter plate 10 inside is set with placing groove 11, filter plate 10 inside is provided with clamping ball 13, clamping ball 13 outer wall is slidably connected in clamping groove 9 inside, clamping ball 13 bottom is fixedly connected with limit disc 14, limit disc 14 outer wall is slidably connected in placing groove 11 inside, filter plate 10 inside is provided with spring one 12, spring one 12 top is fixedly connected in limit disc 14 bottom, spring one 12 bottom is fixedly connected in placing groove 11 inner wall.

[0035] Specifically, when in use, the two side fans 6 can be started to work together. One side fan 6 blows cold air into the temperature insulation box 1, and the other side fan 6 blows the heated air inside out in time to keep the air inside circulating quickly, which can effectively take away the heat around the distance measuring device 7, significantly reduce its temperature, and create a suitable temperature and humidity environment for its stable operation. Good ventilation conditions can timely remove these heat to avoid performance degradation or damage of components due to overheating. Moreover, this heat dissipation method does not require a complex water cooling system, which reduces the complexity and maintenance cost of the equipment. At the same time, the filter plate 10 plays a filtering role and can intercept dust and other impurities in the air. When the filter plate 10 is used for a long time, it may accumulate a lot of dust and affect the filtering effect. At this time, the filter plate 10 can be conveniently pulled out by using the groove inside the filter plate 10. Since the clamping ball 13 is a semicircular structure, it will naturally push the clamping ball 13 to move downward during the pulling process, thereby driving the limiting disc 14 to move downward synchronously and compressing the spring one 12. In this way, the filter plate 10 can be taken out for comprehensive cleaning. After cleaning, it is put back into place again. With the rebounding force of the spring one 12, the clamping ball 13 is pushed into the clamping groove 9 inside to realize the stable fixation of the filter plate 10, ensuring that it continuously and effectively plays a filtering function. It can effectively filter dust, impurities and other small particles in the air. During the operation of the fan 6, external air is sucked into the temperature insulation box 1. If there is no filter plate 10, these dust and impurities will adhere to the surface of the optical elements and electronic elements of the distance measuring device 7, affecting its performance. For example, dust can reduce the light transmittance of optical elements, causing interference in laser emission and reception, while impurities can cause short circuit of electronic elements. The filter plate 10 blocks these adverse factors to ensure the normal operation of the distance measuring device 7.

[0036] With reference to Figure 1 and Figure 2 , the calibration assembly includes an observation window 2 and a filter 8. The outer wall of the observation window 2 is arranged inside the protective door 3, and the outer wall of the filter 8 is arranged inside the temperature insulation box 1.

[0037] Specifically, the observation window 2 provides an approach for the operator to directly observe the internal running state of the distance measuring device. In the process of real-time liquid level monitoring of molten aluminum in a high-temperature environment, the working condition of the distance measuring device can be observed in real time, such as whether the laser emission is normal, whether there is abnormal vibration or displacement of each component, etc. When potential problems or abnormalities are found, the operator can quickly respond and take timely measures to adjust or repair, avoiding interruption or inaccuracy of liquid level monitoring due to equipment failure, thereby ensuring the continuity and stability of the production process. In a high-temperature environment, the molten aluminum emits a large amount of infrared radiation, which interferes with the normal operation of the laser phase distance measuring device and affects the measurement accuracy. The filter 8 can selectively transmit light of a specific wavelength to correct the infrared radiation and reduce its interference with the laser signal.

[0038] With reference to Figure 1and Figure 4 The fixing assembly comprises a transmission rod 16, the outer wall of which is rotationally connected to the inner wall of the temperature insulation box 1, a limiting groove 17 is formed in the inner part of the temperature insulation box 1, and a fixed column 18 is fixedly connected to the inner part of the temperature insulation box 1. The fixed column 18 is an important supporting component in the fixing assembly, which is made of stainless steel and has good strength and corrosion resistance. The outer wall of the fixed column 18 is sleeved with a spring 20, one end of which is fixedly connected to the inner wall of the limiting groove 17, and the other end of which is fixedly connected with a sliding block 24. The outer wall of the sliding block 24 is fixedly connected with a connecting plate 21, which is made of high-strength engineering plastic. The engineering plastic has the advantages of light weight, high strength, good insulation, etc., and can meet the use requirements in high-temperature environment. The outer wall of the connecting plate 21 is slidingly connected in the limiting groove 17, and the outer wall of the connecting plate 21 is fixedly connected with a clamp 15 made of high-temperature-resistant rubber material. The rubber has good elasticity and friction, which can ensure the fixing effect while avoiding damage to the surface of the distance meter 7. The outer wall of the connecting plate 21 is rotationally connected with a rotating column 22, and the outer wall of the rotating column 22 is fixedly connected with a rotating rod 19, the outer wall of which is rotationally connected to the inner part of the transmission rod 16.

[0039] Specifically, when the liquid level of the aluminum liquid needs to be detected, first, the temperature insulation box 1 is placed stably on the top of the aluminum liquid at a suitable position by means of the support 4, and then the protective door 3 is opened, and the clamp 15 is pulled. The movement of the clamp 15 will drive the connecting plate 21 to move, and the movement of the connecting plate 21 will further drive the rotating column 22 to displace, thereby driving the rotating rod 19 to rotate. The rotation of the rotating rod 19 will transmit power to the other rotating rod 19 through the transmission rod 16, so that the other rotating rod 19 also rotates and drives the other connecting plate 21 to move. In this process, the two connecting plates 21 will move relatively, and will stretch the spring 20 when moving. After the distance meter 7 is placed in the two clamps 15, the clamps 15 are loosened, and the spring 20 will use its rebound characteristics to drive the two clamps 15 to move to the center, thereby clamping and fixing the distance meter 7, which can effectively keep the distance meter 7 stable and prevent it from displacing or shaking due to external interference during work, thereby ensuring the accuracy of the liquid level detection. At the same time, the middle part of the bottom clamp 15 is separated, which avoids interference with the measurement process, so that the laser can be smoothly emitted and received, thereby providing a strong guarantee for accurate measurement of the liquid level of the aluminum liquid.

[0040] Working principle: when the liquid level of the aluminum liquid needs to be detected, the temperature insulation box 1 is placed on the top of the aluminum liquid through the support 4, then the protective door 3 is opened, the clamp 15 is pulled, the connecting plate 21 is moved through the clamp 15, then the rotating column 22 is moved through the connecting plate 21, then the rotating column 22 drives the rotating rod 19 to rotate, then the rotating rod 19 drives the transmission rod 16 to rotate, so that the other rotating rod 19 is driven to rotate, thereby driving the other connecting plate 21 to move, so that the two connecting plates 21 move relatively, and the spring two 20 is stretched during movement, then the distance meter 7 is placed in the two clamps 15, then the clamp 15 is loosened, the two clamps 15 are moved to the center through the rebound of the spring two 20, the distance meter 7 is clamped and fixed, and the stability is maintained, and the middle of the bottom clamp 15 is separated, so that the distance measurement is not affected, then the protective door 3 is closed during use, then the two side fans 6 are started, one side fan 6 blows cold air inside, and the other side fan 6 blows hot air inside, so that the air inside is circulated, the temperature of the distance meter 7 is reduced, and the dust is filtered through the filter plate 10, when used for a long time, the filter plate 10 can be pulled through the groove in the filter plate 10, because the clamping ball 13 is semicircular, so that the clamping ball 13 is pushed down, then the limiting disc 14 is driven to move downward, so that the spring one 12 is compressed, so that it is taken out for cleaning, then it is placed back again, and the clamping ball 13 is clamped into the clamping groove 9 through the rebound of the spring one 12.

[0041] Finally, it should be pointed out that: the above only preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the person skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
