Abstract
Description
Technical Field
[0001] This utility model relates to the field of special instrument manufacturing technology, and in particular to a real-time data acquisition instrument for wireless transmission in continuous high-temperature environments. Background Technology
[0002] In many industrial settings, such as metallurgy, building materials, chemicals, and energy, continuous and accurate monitoring of the internal temperature of processes or equipment at 500℃ and above is often required. Traditional high-temperature temperature acquisition instruments primarily employ a metal insulated casing combined with insulation materials such as asbestos, which has the following significant limitations: First, their insulation performance is limited. Under long-term high-temperature environments, the internal electronic compartment experiences significant temperature rise, resulting in a harsh working environment for core electronic components, low reliability, and a mean time between failures (MTBF) typically of only around 2000 hours, making it difficult to meet the requirements for long-term stable operation. Second, traditional metal casings severely shield wireless signals and lack effective high-temperature antenna design, resulting in short wireless transmission distances and unstable signals. Data often still relies on offline export via memory cards, leading to a serious data lag problem of "card retrieval—card reading—post-processing," making true real-time monitoring and immediate feedback impossible.
[0003] Furthermore, existing insulation layers often use asbestos-containing materials, which not only suffer from powdering and moisture absorption leading to performance degradation, but also release carcinogenic dust, endangering human health and environmental safety. Traditional metal shells are heavy, inconvenient to handle and install, and have limited resistance to oxidation and thermal shock. They are easily damaged under harsh thermal cycling conditions, requiring frequent opening and maintenance, with annual maintenance hours reaching up to 32 hours, resulting in high operating costs and high labor intensity.
[0004] The present invention aims to solve the technical problems existing in the prior art. To this end, a real-time data acquisition instrument for wireless transmission in a continuous high-temperature environment is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a real-time data acquisition instrument for wireless transmission in continuous high-temperature environments, so as to solve the technical problems existing in the prior art.
[0006] By adopting the above technical solution, this utility model has the following beneficial effects:
[0007] This utility model provides a real-time data acquisition instrument for wireless transmission in a continuous high-temperature environment, comprising a high-temperature ceramic shell, a double-layer gradient sand layer on the inner side of the high-temperature ceramic shell, a high-temperature cotton layer on the inner side of the double-layer gradient sand layer, and an electronic compartment on the inner side of the high-temperature cotton layer; a temperature detector is installed inside the electronic compartment.
[0008] As a further embodiment of this utility model: the outer surface of the high-temperature ceramic shell is sprayed with a black CoO-MnO2 far-infrared radiation coating.
[0009] As a further embodiment of this utility model: the double-layer gradient sand layer includes an outer gradient sand layer and an inner gradient sand layer, wherein the outer gradient sand layer is filled with quartz sand and the inner gradient sand layer is filled with fine sand.
[0010] As a further embodiment of this utility model: the high-temperature cotton layer is made of three layers of Al2O3-SiO2 soluble ceramic fiber blanket.
[0011] As a further embodiment of this utility model: the high-temperature ceramic shell, the double-layer gradient sand layer, and the high-temperature cotton layer are circumferentially clamped together by a molybdenum wire mesh.
[0012] As a further embodiment of this utility model: a battery compartment is provided in the electronic compartment on one side of the temperature detector, and a power supply is provided in the battery compartment.
[0013] As a further improvement of this utility model, the temperature detector includes a wireless module, a main control MCU, and a sensor.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] I. Superior thermal insulation performance and improved reliability
[0016] High-efficiency thermal insulation system: It adopts a composite thermal insulation structure of "high-temperature ceramic shell - double-layer gradient sand layer - high-temperature cotton layer", and is tightened circumferentially by molybdenum wire mesh to ensure overall stability.
[0017] Protection of critical components: In extreme environments where the hot surface temperature reaches 500℃, the internal electronic compartment temperature rise is ≤55℃, and the thermocouple cold junction compensation error is ≤±0.5℃, providing a reliable working environment for core electronic components.
[0018] Significantly enhanced reliability: The mean time between failures (MTBF) of the entire machine has been greatly increased from the traditional 2,000 hours to more than 10,000 hours, ensuring long-term stable operation in continuous high-temperature environments.
[0019] II. Excellent wireless transmission performance and real-time data processing capabilities
[0020] High signal transmission and low attenuation: The high-temperature ceramic shell has an RF transmittance of >92%, and combined with the built-in 2.4GHz high-temperature resistant microstrip antenna, the signal attenuation is <3dB at 500℃, and the line-of-sight transmission distance is ≥50m, ensuring the stability of wireless communication.
[0021] True real-time monitoring: The data update cycle is shortened to 1 second, and data can be received synchronously via a host computer or mobile APP to plot real-time temperature curves. This completely changes the traditional "card retrieval-card reading-post-processing" mode, solves the problem of hour-level lag in data acquisition, and realizes instant monitoring and feedback of high-temperature processes.
[0022] III. Design advantages of long lifespan and low maintenance
[0023] High material durability: The high-temperature ceramic shell has excellent anti-oxidation and thermal shock resistance, and can withstand more than 1,000 thermal cycles, which greatly extends the service life of the shell.
[0024] Extended maintenance cycle and significantly reduced working hours: No need for quarterly on-site maintenance, annual maintenance hours are reduced from 32 hours to 6 hours, reducing long-term operation and maintenance costs and manpower input.
[0025] Stable internal structure: The double-layer gradient sand layer adopts an asbestos-free design, which fundamentally eliminates the problems of traditional thermal insulation materials such as easy powdering and performance degradation caused by moisture absorption, and ensures the durability of thermal insulation effect.
[0026] IV. Environmental Protection, Safety and Human-Centered Improvements
[0027] Safety and health: Complete elimination of carcinogen asbestos, eliminating dust health risks to operators and the environment, and meeting modern industrial safety and environmental protection standards.
[0028] Lightweight design: High-temperature ceramic shell with a bulk density of <2.8g / cm³ 3 The overall weight is reduced by 35% compared to traditional metal casings, significantly reducing the labor intensity of handling and installing the equipment.
[0029] Comprehensive environmental improvement: From material selection to long-life design, the environmental friendliness and sustainability of the products have been comprehensively improved. Attached Figure Description
