Description

Technical Field

[0001] The present invention relates to the technical field of liquid level gauges, in particular to a copper liquid level gauge. Background Art

[0002] In the production process of copper smelting enterprises, accurately controlling the liquid level of molten copper in the furnace is a key link to ensure production safety and efficiency. Due to the extremely high temperature in the furnace, usually reaching around 1300°C, this extreme environment poses a severe challenge to liquid level measurement technology. Traditional liquid level gauges, such as float or magnetic flap level gauges, have difficulty working normally under such high temperature conditions and may even be quickly damaged or fail due to the material's inability to withstand high temperatures. Therefore, radar level gauges have been widely used in the copper smelting industry due to their non-contact measurement characteristics. Radar level gauges transmit high-frequency electromagnetic waves (radar waves) and receive the signals reflected from the liquid surface, using the time difference to calculate the liquid level. They have the advantages of accurate measurement and are not affected by the physical properties of the medium.

[0003] Although radar level meters are widely used in the industrial field due to their non-contact measurement, high accuracy and wide adaptability, when directly installed on the furnace detection seat, they still face the problem of being easily damaged and malfunctioning due to high temperature.

[0017] 2. The present invention has designed a quartz glass thermal insulation assembly, which significantly improves the operational stability of the radar level gauge body in high-temperature environments.

The heat dissipation tube is a core component, and its excellent heat dissipation performance effectively evacuates heat, significantly reducing the heat load on the thermal insulation tube and the radar level gauge body. What is particularly unique is that the assembly also incorporates an automatic lifting mechanism.

Regardless of the height of the radar level gauge, the system can ensure accurate measurement results, greatly improving reliability and measurement accuracy.

[0021] 6.

In order to further reduce the impact of high temperature on the radar level meter body 1, the present invention sets a quartz glass thermal insulation component 31 between the thermal insulation tube 33 and the detection seat, which significantly improves the operating stability of the radar level meter body 1 in a high temperature environment. Specifically, the core of the component lies in the double insulation design: first, a high-melting-point first thermal insulation pad 311 (i.e., aluminum silicate cotton roll felt) is used as the first thermal insulation barrier, and its melting point exceeds 1700°C, demonstrating excellent high-temperature resistance. Next is quartz glass 315, which can withstand continuous high temperatures of up to 1200°C and can even withstand extreme temperatures of 1400°C for short periods of time, further enhancing the thermal insulation effect. This ingenious combination of double insulation structures not only effectively isolates the high-temperature heat from the detection seat, but also greatly reduces the direct impact and potential damage of high temperature on the radar level gauge body 1, ensuring accurate measurement and long-term stable operation of the instrument under harsh working conditions. This design not only improves the performance of the equipment, but also extends its service life, demonstrating excellent performance and technological innovation value. To further reduce the impact of high temperature on the radar level gauge body 1, the device provides a heat dissipation fin tube assembly 32 between the quartz glass insulation assembly 31 and the thermal insulation tube 33. The heat dissipation tube 322 is a core component. Its excellent heat dissipation performance effectively dissipates heat, significantly reducing the heat load on the thermal insulation tube 33 and the radar level gauge body 1, and achieving good performance.

[0042] It should be noted that the first thermal insulation pad 311 described in this embodiment is aluminum silicate cotton felt, and the second thermal insulation pad 323, the third thermal insulation pad 324 and the thermal insulation seat 325 are all made of ceramic fiber material. The high temperature resistance of ceramic fiber can reach above 1000°C. In order to improve the thermal insulation effect, a multi-layer reflective film (not shown in the figure) is also provided on the outer surface of the thermal insulation tube 33. The multi-layer reflective film is composed of multiple layers of metal films and polymer films alternately stacked, which reduces heat conduction by reflecting and scattering thermal radiation.

[0043] It should also be noted that the quartz glass 315 described in this embodiment has a disc-shaped center through-hole structure. To facilitate the fixation of the quartz glass 315, limit rings are respectively provided at the top of the lower positioning plate 314 and the bottom of the upper fixed plate 316. The quartz glass 315 is snap-fitted and fixed to the inner wall of the limit ring. To facilitate the entry of radar waves into the furnace body, the heat dissipation tube 322, the upper fixed plate 316, the quartz glass 315, the lower positioning plate 314, the fixed flange 312, the first thermal insulation pad 311 and the horn antenna 2 are internally connected.

[0044] Specifically, the structure and connection relationship of the quartz glass insulation assembly 31, the heat dissipating fin assembly 32 and the thermal insulation tube 33 are further explained. When in use, the first insulation pad 311, the quartz glass 315, the second insulation pad 323, the third insulation pad 324, the insulation holder 325 and the vacuum chamber of the thermal insulation tube 33 can effectively play a heat insulation effect. The heat dissipating tube 322 effectively dissipates heat with its excellent heat dissipation performance, significantly reducing the heat load on the thermal insulation tube 33 and the radar level meter body 1, and has a good use effect.

[0045] In one embodiment of the present invention, Figure 1-Figure 2 and Figure 5 As shown, the heat dissipation tube 322 also includes a lifting component 4, which is used to automatically drive the thermal insulation tube 33 and the radar level gauge body 1 to rise to a set height when the surface temperature of the lower end of the heat dissipation tube 322 is higher than the set maximum temperature value, and automatically drive the thermal insulation tube 33 and the radar level gauge body 1 to reset to the initial height when the surface temperature of the lower end of the heat dissipation tube 322 is lower than the set minimum temperature value.

[0046] Specifically, the lifting component 4 can automatically raise the position of the thermal insulation tube 33 and the radar level meter body 1 when the surface temperature of the lower end of the heat dissipation tube 322 reaches the set temperature, further reducing the impact of the high temperature environment through physical isolation, showing a high degree of flexibility.

[0047] In one embodiment of the present invention, Figure 1-Figure 2 and Figure 5 As shown, the lifting assembly 4 includes a heat-conducting block 41, a guide tube 42, a spring-type memory alloy 43 and a limiting guide column 44, wherein the heat-conducting block 41 is fixedly connected to the inner wall of the lower end of the heat dissipation tube 322, the guide tube 42 is slidably connected to the inner wall of the heat-conducting block 41, the spring-type memory alloy 43 is sleeved on the outside of the guide tube 42, one end of the spring-type memory alloy 43 is fixedly connected to the surface of the heat-conducting block 41, and the other end of the spring-type memory alloy 43 is fixedly connected to the surface of the guide tube 42, the limiting guide column 44 is vertically slidably connected to the inner wall of the heat-insulating holder 325, one end of the limiting guide column 44 passes through the interior of the heat dissipation tube 322 and is fixedly connected to the top of the guide tube 42, the other end of the limiting guide column 44 passes through the top of the heat-insulating holder 325 and is fixedly connected to the bottom of the thermal insulation tube 33, the guide tube 42 and the limiting guide column 44 are both hollow structures, and the interior of the guide tube 42, the interior of the limiting guide column 44 and the interior of the thermal insulation tube 33 are connected.

[0048] It should be noted that the spring type memory alloy 43 described in this embodiment is a two-way memory alloy, and the high temperature deformation temperature of the spring type memory alloy 43 is 100°, and the low temperature deformation temperature is 60°.

[0049] Specifically, the structure and connection relationship of the lifting assembly 4 are further explained. When in use, the heat on the inner wall of the lower end of the heat dissipation tube 322 is conducted to the guide tube 42 and the spring-type memory alloy 43 through the heat-conducting block 41. When the temperature is higher than the high-temperature deformation temperature of the spring-type memory alloy 43 (i.e., 100°), the spring-type memory alloy 43 is deformed by the heat, and its height dimension changes, and the guide tube 42 is simultaneously driven to move upward along the inner wall of the heat-conducting block 41. The movement of the guide tube 42 simultaneously drives the limiting guide column 44 to move vertically upward along the inner wall of the heat-insulating holder 325. The movement of the limiting guide column 44 simultaneously drives the thermal insulation tube 33 and the radar level gauge body 1 to move upward synchronously, thereby staying away from the heat source, further reducing the impact of high temperature on the radar level gauge body 1, and having a good use effect.

[0050] In one embodiment of the present invention, Figure 1-Figure 2 and Figure 5 As shown, the limiting guide column 44 also includes an umbrella-type isolation component 5, which can be automatically activated when the limiting guide column 44 rises. Once started, the umbrella-type isolation component 5 will quickly unfold between the heat dissipation tube 322 and the thermal insulation tube 33 and form an insulation barrier, effectively blocking the heat transfer path from the heat dissipation tube 322 to the thermal insulation tube 33, and significantly improving the thermal insulation performance.

[0051] Specifically, the umbrella-type isolation assembly 5 is provided to block the heat transfer path from the heat dissipation tube 322 to the thermal insulation tube 33 , thereby further improving the thermal insulation performance.

[0052] In one embodiment of the present invention, Figure 5As shown, the umbrella-type isolation assembly 5 includes an outer cylinder 51, a fixed end 52, a support rod 53, a slide 54, a hinged seat 55, a connecting rod 56, a heat shield 57, a synchronization rod 58 and a displacement detection assembly 59, wherein the outer cylinder 51 is threadedly connected to the top of the heat dissipation cylinder 322 and is sleeved on the outside of the limiting guide column 44, the fixed end 52 is fixedly connected to the top of the outer cylinder 51, the support rod 53 is evenly rotated and connected to the bottom of the fixed end 52, and the slide 54 is vertically slidably connected to the outer surface of the outer cylinder 51 and is located at the bottom of the fixed end 52. On one side of the body, the top of the slide 54 and the bottom of the support rod 53 are fixedly connected with a hinge seat 55 respectively, and are connected by a connecting rod 56. The heat shield 57 is fixedly connected to the top of the support rod 53. The synchronization rod 58 is evenly slidably connected to the inner wall of the outer cylinder 51. One end of the synchronization rod 58 passes through the outside of the outer cylinder 51 and is fixedly connected to the bottom of the slide 54. The other end of the synchronization rod 58 passes through the inside of the heat dissipation cylinder 322 and is fixedly connected to the surface of the annular platform 45 set on the surface of the limit guide column 44. The displacement detection component 59 is used to realize The displacement data of the radar level gauge body 1 during the lifting process is monitored in real time to ensure that the measuring height can be adjusted quickly and accurately. The displacement detection component 59 includes an inner rod 591, an outer sleeve 592 and a displacement sensor 593, wherein the inner rod 591 is slidably connected to the inner wall of the outer cylinder 51, and the outer sleeve 592 is fixedly connected to the bottom of the slide 54. One end of the inner rod 591 passes through the interior of the heat dissipation cylinder 322 and is fixedly connected to the surface of the annular platform 45 set on the surface of the limiting guide column 44. The other end of the inner rod 591 passes through the outside of the outer cylinder 51 and is slidably connected to the inner wall of the outer sleeve 592. The displacement sensor 593 is fixedly connected to the surface of the outer sleeve 592. The displacement sensor 593 determines the position of the inner rod 591 by measuring the relative displacement between the inner rod 591 and the outer sleeve 592. The displacement sensor 593 sends the detected data information to the external control system. The external control system receives the displacement data measured in real time by the displacement sensor 593 and the height data provided by the radar level gauge body 1, obtains the new height difference through accurate calculation, and dynamically adjusts the measurement data accordingly.

[0053] It should be noted that the displacement sensor 593 described in this embodiment is a prior art and will not be described in detail here.

[0054] It should also be noted that in order to effectively alleviate the challenges brought by the height factor to detection accuracy, the present invention sets a ring signal enhancer 100 inside the heat dissipation tube 322. This device, with its excellent penetration enhancement technology, significantly improves the ability of the signal to traverse long distances or complex environments. At the same time, it deeply optimizes the signal transmission quality, effectively curbs the signal attenuation phenomenon, and ensures that the signal is clear and stable. In addition, it also has excellent resistance to environmental noise interference, greatly reducing the impact of external interference on the signal. For extremely harsh measurement environments such as high temperature, high pressure and strong corrosion, the ring signal enhancer 100 of the present invention can serve as a solid barrier and is cleverly deployed between the radar level meter body 1 and the measured medium, successfully isolating the harsh environment from the erosion of the radar level meter body 1, and significantly improving the protection level of the equipment. This innovative design not only ensures the stable operation of the radar level meter body 1 under extreme conditions, but also significantly extends its service life, showing excellent use effect and practical value.

[0055] Specifically, the structure and connection relationship of the umbrella-type isolation component 5 are further explained. When in use, the limit guide column 44 rises and synchronously drives the annular platform 45 to rise. The rise of the annular platform 45 synchronously drives the synchronization rod 58 and the inner rod 591 to move upward. The synchronization rod 58 moves upward and synchronously drives the slide 54 to move upward along the surface of the outer cylinder 51. Through the cooperation of the hinged seat 55 and the connecting rod 56, the support rod 53 and the heat insulation cover 57 are synchronously driven to unfold. The unfolded heat insulation cover 57 forms a heat insulation barrier between the heat dissipation cylinder 322 and the heat insulation cylinder 33. It effectively blocks the heat transfer path from the heat dissipation tube 322 to the thermal insulation tube 33, significantly improving the thermal insulation performance. The displacement sensor 593 determines the position of the inner rod 591 by measuring the relative displacement between the inner rod 591 and the outer sleeve 592. The displacement sensor 593 sends the detected data information to the external control system. The external control system receives the displacement data measured in real time by the displacement sensor 593 and the height data provided by the radar level meter body 1, obtains the new height difference through precise calculation, and dynamically adjusts the measurement data accordingly to ensure accurate measurement.

[0056] In one embodiment of the present invention, Figure 6 As shown, the heat insulation cover 57 is formed by a tight combination of high-strength base cloth and high-performance silica composite aerogel, wherein the base cloth is precisely woven from high-quality polyester and high-strength glass fiber in a scientifically preset ratio. The surface of the heat insulation cover 57 on one side close to the heat dissipation tube 322 is also provided with an infrared reflective coating layer 6.

[0057] Specifically, the structure of the heat insulation cover 57 is further explained. The base cloth serves as a carrier of the silica composite aerogel, and the silica composite aerogel can insulate a high temperature of 1300° to about 300°, and has a good use effect. In order to further improve the thermal insulation performance of the heat insulation cover 57, an infrared reflective coating layer 6 is also provided on the surface of the heat insulation cover 57. The infrared reflective coating layer 6 can reflect high heat and resist high temperature radiation, while absorbing radiation of different wavelengths, further playing a heat insulation role, and has a good use effect.

[0058] In summary, a copper liquid level meter in an embodiment of the present invention innovatively connects in series a quartz glass insulation component 31, an efficient heat dissipation fin component 32 and a thermal insulation tube 33 between the radar level meter body 1 and the detection seat. This design not only significantly improves the thermal insulation performance, effectively blocks the direct impact of the high temperature of the furnace body on the radar level meter body 1, but also greatly enhances the heat dissipation and cooling effects through the introduction of the heat dissipation fin component 32. This fundamentally solves the long-standing problem of radar level meters faced by copper smelting enterprises, which are frequently damaged and fail to function due to extreme high temperature environments, and ensures the stable operation and precise measurement of the radar level meter body 1 under harsh working conditions, providing a solid guarantee for the safety and efficiency of enterprise production.
