Description
Technical Field
[0001] This application relates to the field of flame detection and temperature measurement technology, and in particular to a flame detector with temperature measurement function. Background Technology
[0002] This instrument was developed to address the challenge of measuring flame temperature in high-temperature and high-pressure reactors or gasifiers in coal chemical and chemical industries. Flames are characterized by instability, large temperature distribution differences, and the presence of particulate matter or soot, making it difficult to directly and accurately measure flame temperature. However, flame temperature is a key thermodynamic parameter in the combustion process, hence the development of this instrument.
[0003] A search revealed Chinese Patent Publication No. CN215411973U, which discloses a combined explosion-proof enclosure. The enclosure forms an explosion-proof cavity, within which a circuit detection component is installed. A cable access component is also embedded in the enclosure. The output end of the cable access component is electrically connected to the circuit detection component, and the input end is electrically connected to an external cable. The enclosure is formed by a cover and a body connected by threads. The outer side of the cover's threaded end has a first thread, and the inner side of the body's threaded end has a second thread. The first and second threads are compatible. The outer side of the cover has an outwardly protruding annular limiting protrusion for limiting the end face of the body. An anti-loosening screw is screwed onto the open end face of the body, with the outer end of the anti-loosening screw abutting against the annular limiting protrusion.
[0004] Although the aforementioned patent improves the sealing effect of the explosion-proof cavity by using a threaded connection between the cover and the body, it is too complicated when the equipment needs to be repaired. Therefore, a flame detector with temperature measurement function is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this application is to provide a flame detector with temperature measurement function, which aims to solve the problem of inconvenient disassembly and installation during maintenance.
[0006] The flame detector with temperature measurement function provided in this application adopts the following technical solution: a flame detector with temperature measurement function includes a shell, a flame detection and measurement mechanism is fixedly connected to the inner wall of the shell, a quick installation mechanism is fixedly connected to the outer side of the shell, a docking mechanism is fixedly connected to the outer side of the shell, and a handle is fixedly connected to the bottom of the shell. The quick-installation mechanism includes multiple connecting blocks, which are externally fixedly connected to the outside of the housing. A protective shell is fixedly connected to the outside of each connecting block, and a spring body is fixedly connected to the inner wall of the protective shell. A limit ring is fixedly connected to the other end of the spring body, and a connecting assembly is slidably connected to the outside of the limit ring.
[0007] Through the above technical solution: the shell serves as the core carrier, integrating a flame detection and measurement mechanism to ensure operational safety, while the quick installation mechanism, docking mechanism, and handle work together to improve ease of use. In the quick installation mechanism, the connecting block and the protective shell form a stable frame, and the spring body drives the limit ring to engage with the connecting component, enabling rapid installation and disassembly, greatly improving the efficiency of equipment assembly and maintenance, and meeting diverse operational needs.
[0008] Preferably, the docking mechanism includes a docking tube, the outside of which is fixedly connected to the outside of the housing, a sliding ring is slidably connected to the outside of the docking tube, a spring is fixedly connected to the inner wall of the sliding ring, a sealing ring is fixedly connected to the inner wall of the docking tube, and a positioning tube is slidably connected to the outside of the sealing ring.
[0009] By adopting the above technical solution, a solid connection foundation is provided for fixing the connecting pipe to the outer shell; the sliding ring works with spring two, and when pressed, the spring is compressed to achieve pre-positioning, and when released, the spring returns to its original position and applies a 15N pre-tightening force to ensure a tight connection; the sealing ring is made of highly elastic rubber material and is interference-fitted with the positioning tube to form a zero-leakage seal; the positioning tube can slide along the sealing ring, which is convenient for quick alignment and insertion. The entire structure can achieve rapid docking within 3 seconds, effectively improving the equipment connection efficiency and sealing safety.
[0010] Preferably, a positioning ring is fixedly connected to the outside of the connecting pipe, and the inner wall of the sliding ring is slidably connected to the positioning ring.
[0011] By adopting the above technical solution, precise guidance and stroke limitation are provided for the sliding ring. The positioning ring is tightly fixed to the outside of the docking tube and forms a precise clearance fit with the inner wall of the sliding ring, ensuring that the sliding ring always maintains coaxiality during the sliding process, avoiding offset and jamming, and making the docking operation smoother. At the same time, the positioning ring limits the sliding stroke of the sliding ring, preventing it from sliding excessively and detaching from the docking tube. Combined with the reset action of the second spring, it ensures the stable operation of the sliding ring during docking and reset, and improves the overall reliability of the docking mechanism.
[0012] Preferably, the inner wall of the connecting tube is slidably connected with a ball bearing, and the outer side of the positioning tube is provided with a positioning groove, and the outer side of the ball bearing is slidably connected to the inner wall of the positioning groove.
[0013] By adopting the above technical solution, the ball bearing and positioning groove are designed to fit together. When the connecting pipe and positioning pipe are connected, the ball bearing is squeezed out by the slip ring and embedded in the positioning groove, forming a multi-point contact mechanical lock. It can withstand a lateral tensile force of more than 80N. This structure not only reduces the frictional resistance during docking and makes the operation smoother, but also effectively prevents the pipeline from loosening or slipping during stirring and vibration. Combined with the sealing ring, it achieves a high airtight connection, ensuring stable and leak-free transmission of detection signals.
[0014] Preferably, the connecting assembly includes a fixing block, the fixing block being externally movably connected to the outside of the protective shell, a limiting groove being formed on the outside of the fixing block, and the inner wall of the limiting ring being slidably connected to the inner wall of the limiting groove.
[0015] By adopting the above technical solution, the movable connection design between the fixed block and the protective shell allows the connecting components to be flexibly adjusted to adapt to different installation requirements. The sliding cooperation between the limiting groove and the limiting ring forms a mechanical locking structure. When inserted, the limiting ring slides along the groove and automatically engages under the action of the spring body, providing a tensile force of more than 50N to prevent accidental detachment. When disassembling, pressing can unlock the device without tools, significantly improving the efficiency of equipment disassembly and assembly and the convenience of use.
[0016] Preferably, the fixing block is fixedly connected to the outside of a fixing shell, and the inner wall of the fixing shell is fixedly connected to a protective cover.
[0017] By adopting the above technical solution, a double-layer protective and reinforced structure is formed. The fixed shell is made of high-strength metal material, which provides rigid support for the fixed block, effectively resists external collisions and vibrations, and prevents the connection from becoming loose. The protective cover fits tightly against the inner wall of the fixed shell and is made of insulating and wear-resistant material, which can isolate mortar splashes and dust intrusion, protect internal wires and sensitive components, and significantly improve the durability and connection stability of the equipment.
[0018] Preferably, the flame detection and measurement mechanism includes a heat insulation layer, the outside of which is fixedly connected to the inner wall of the outer shell, and a fixing plate is fixedly connected to the inner wall of the heat insulation layer.
[0019] By adopting the above technical solution, the heat insulation layer is made of high-temperature resistant ceramic fiber material. Its low thermal conductivity can effectively block the high temperature in the stirring chamber from being conducted into the equipment, significantly extending the service life of electronic components. The heat insulation layer is tightly attached to the inner wall of the outer shell, forming a seamless protective barrier to avoid heat convection affecting the detection accuracy. The fixing plate, as the structural skeleton, is made of high-strength aluminum alloy and is connected to the heat insulation layer through a precision welding process. This ensures that components such as signal sensors and infrared detectors remain stable during intense stirring operations, providing a solid physical support and protective foundation for the flame detection system.
[0020] Preferably, a signal sensor is fixedly connected to the top of the fixing plate, an infrared detector is fixedly connected to the outside of the signal sensor, the infrared detector is fixedly connected to the inner wall of the heat insulation layer, a wire is fixedly connected to the outside of the signal sensor, and the other end of the wire is fixedly connected to the outside of the protective cover.
[0021] By adopting the above technical solution, the signal sensor and the infrared detector work together. The former captures temperature and flame signals, while the latter uses infrared rays to accurately detect heat sources. Dual detection improves the accuracy of early warning. The wire connection to the protective cover ensures stable data transmission and facilitates maintenance. The heat insulation layer and fixing plate provide physical protection and structural support, effectively isolating high temperature and vibration, ensuring stable operation of the detection element under complex working conditions, and comprehensively protecting equipment safety.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, when the outer shell is damaged, pressing the fixing block on the fixing shell will cause the limiting block to move by sliding, thereby releasing the control of the limiting block by the protective shell. At this time, the spring body will automatically act to quickly slide the limiting block back to its original position. Since the sliding of the limiting block is no longer restricted by the protective shell, the detection process becomes faster and more efficient. 2. In this utility model, the sliding ring precisely connects the connecting tube and the positioning tube. At this time, the second spring restricts the sliding ring to slide back to its original position, the positioning ring further prevents the sliding ring from falling off, the ball and the positioning groove interact to better fix the position of the positioning tube, and the sealing ring ensures the sealing of the connection, thereby achieving accurate detection.

Detailed Implementation
[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.
[0025] Example 1: A flame detector with temperature measurement function, referring to... Figures 1 to 3 The device includes: a housing 1, with a flame detection and measurement mechanism 2 fixedly connected to the inner wall of the housing 1. This mechanism 2 can monitor potential flames or heat sources in real time, ensuring the safety of the equipment during operation in high-temperature environments. A quick-installation mechanism 3 is fixedly connected to the outside of the housing 1, allowing the device to be quickly connected to other devices or modules, improving work efficiency. A docking mechanism 4 is also fixedly connected to the outside of the housing 1, facilitating docking of the device with other components and improving operational convenience. A handle 5 is fixedly connected to the bottom of the housing 1, making it easier for operators to move or adjust the equipment, especially when rapid movement is required. The handle 5 provides a stable support point. In the quick-installation mechanism 3, multiple connecting blocks 31 are evenly distributed on the outside of the housing 1, serving as a fixed base to ensure structural stability. A protective shell 32 encloses the connecting blocks 31, and a spring body 33 and a limiting ring 35 are installed inside to form an elastic locking system. When the connecting component 34 approaches, the limiting ring 35 is compressed by the spring body 33. When the connecting component 34 is in place, the spring body 33 rebounds and pushes the limiting ring 35 into the limiting structure of the connecting component 34, achieving quick locking and withstanding a 50N pulling force without loosening. During disassembly, pressing the protective shell 32 triggers unlocking, and the limiting ring 35 compresses the spring body 33 to disengage. No tools are required throughout the process. The connecting component 34 includes a fixing block 341, which is movably connected to the outside of the protective shell 32. The position of the fixing block 341 can be adjusted so that the protective shell 32 can better adapt to different working conditions. A limiting groove 342 is provided on the outside of the fixing block 341, which serves to limit and prevent the fixing block 341 from shifting during use. The inner wall of the limiting ring 35 is slidably connected to the inner wall of the limiting groove 342 to ensure that the fixing block 341 will not fall off during operation, thus improving the stability of the structure. A fixing shell 343 is fixedly connected to the outside of the fixing block 341, which further strengthens the stability of the fixing block 341 and prevents the equipment from loosening during long-term use. A protective cover 344 is fixedly connected to the inner wall of the fixing shell 343, which can effectively protect the sensitive components inside the equipment from external physical impacts, increasing the durability of the equipment. Specifically, the inner wall flame detection and measurement mechanism 2 is equipped with an infrared detector 25 and a signal sensor 23 to capture heat source signals in real time, building a solid safety barrier for high-temperature operations. The quick installation mechanism 3, through the interlocking design of the limiting ring 35 and the limiting groove 342, enables the equipment and module to be disassembled and assembled in seconds, greatly improving work efficiency. The docking mechanism 4, with the locking of the ball bearing 47 and the positioning groove 48, combined with the sealing ring 44, ensures that the pipeline connection is stable and leak-free. The bottom handle 5 optimizes the grip and facilitates flexible movement of the equipment. In the connecting component 34, the fixing block 341 is flexibly adjustable within the protective shell 32, and is reinforced by the fixing shell 343 and protected by the protective cover 344, effectively resisting external impacts and extending the service life of the equipment.
[0026] Reference Figure 2 and Figure 4 The docking mechanism 4 includes a connecting pipe 41, which is externally fixedly connected to the outer casing 1 to ensure a secure pipe connection during docking. A sliding ring 42 is slidably connected to the outside of the connecting pipe 41, allowing for flexible sliding during docking and ensuring a smooth docking process. A spring 43 is fixedly connected to the inner wall of the sliding ring 42; when the sliding ring 42 slides, the spring 43 provides a counterforce, pulling the sliding ring 42 back to its original position and preventing it from slipping out. A sealing ring 44 is fixedly connected to the inner wall of the connecting pipe 41, ensuring a tighter connection during docking and preventing gas or liquid leakage. A positioning tube 45 is slidably connected to the outside of the sealing ring 44, further securing the connection between the connecting pipe 41 and the positioning tube 45, ensuring stability and sealing effect during docking. The connecting pipe 41 is externally fixedly connected to... A positioning ring 46 is provided to ensure that the sliding ring 42 will not fall off accidentally during the docking process, making the docking process more stable. The inner wall of the sliding ring 42 is slidably connected to the positioning ring 46, which guides the sliding ring 42 so that it slides smoothly without deviating from the track, thereby improving the accuracy and stability of the connection. A ball bearing 47 is slidably connected to the inner wall of the docking tube 41. The ball bearing 47 can reduce friction during the docking process, making the sliding smoother. A positioning groove 48 is provided on the outside of the positioning tube 45. The positioning groove 48 provides a fixed track for the ball bearing 47, ensuring that the ball bearing 47 will not fall off during the sliding process. The ball bearing 47 is slidably connected to the inner wall of the positioning groove 48, ensuring the stable restriction of the positioning tube 45 and effectively avoiding loosening or slippage that may occur during the docking process. Specifically, the docking mechanism 4 uses the connecting pipe 41 as the core connection and is fixed to the outer shell 1, providing a stable base for pipe docking. During operation, the sliding ring 42 is pushed to slide along the connecting pipe 41, compressing the inner wall spring 43 to accumulate elastic potential energy. After the connecting pipe 41 is inserted into the positioning tube 45, the spring 43 releases its elastic force, causing the sliding ring 42 to return to its original position and press against the end face of the positioning tube 45, completing the initial fixation. The positioning ring 46 is fixed to the outside of the connecting pipe 41. Through precise clearance fit, it not only limits the sliding stroke of the sliding ring 42 to prevent it from detaching from the connecting pipe 41, but also plays a guiding role, ensuring that the sliding ring 42 slides smoothly. The ball bearing 47 is embedded in the inner wall of the connecting pipe 41 and pops out as the sliding ring 42 slides, locking into the positioning groove 48 of the positioning tube 45 to form a secondary lock, which can withstand strong vibrations without loosening. At the same time, the sealing ring 44 tightly fits the outer wall of the positioning tube 45, using interference fit to fill the gap, achieving a high airtight connection, effectively preventing gas or liquid leakage, and ensuring the accuracy of flame detection data and the stability of device operation.
[0027] Reference Figure 1 and Figure 2 The flame detection and measurement mechanism 2 includes a heat insulation layer 21, which effectively isolates the high-temperature environment from the outside, preventing heat damage to internal components and thus extending the service life of the equipment. The heat insulation layer 21 is externally fixedly connected to the inner wall of the outer casing 1, ensuring a secure connection between the heat insulation layer 21 and the outer casing 1. A fixing plate 22 is fixedly connected to the inner wall of the heat insulation layer 21, providing additional support and stability to ensure that the heat insulation layer 21 will not shift due to vibration or external forces. A signal sensor 23 is fixedly connected to the top of the fixing plate 22, which can detect the internal temperature and flame signal of the equipment. The safety alarm system provides necessary data support. An infrared detector 25 is fixed to the outside of the signal sensor 23. The infrared detector 25 detects changes in heat sources around the device by infrared radiation, which further enhances the accuracy of flame detection. The infrared detector 25 is fixedly connected to the inner wall of the heat insulation layer 21 to ensure its stable position and resistance to external interference. A wire 24 is fixedly connected to the outside of the signal sensor 23. The wire 24 transmits the data collected by the sensor to the external control system. The other end of the wire 24 is fixedly connected to the outside of the protective cover 344 to ensure that the connection of the wire 24 is safe and stable, and facilitates future maintenance or replacement. Specifically, the flame detection and measurement mechanism 2 achieves accurate monitoring and long-term protection through a multi-layered structure. The heat insulation layer 21, made of high-temperature resistant ceramic fiber, fits tightly against the inner wall of the outer shell 1, effectively isolating the high temperature of the stirring chamber and protecting the internal components. The fixing plate 22 serves as a supporting frame, enhancing the stability of the heat insulation layer 21 and resisting operational vibrations. The signal sensor 23 and the infrared detector 25 are integrated inside the heat insulation layer 21. The former captures temperature and flame signals in real time, while the latter uses infrared light to accurately detect changes in the heat source. The complementary data from both enhances detection accuracy. The wire 24 connects the sensor to the external system, with its end fixed to the protective cover 344, ensuring stable data transmission and facilitating later maintenance. The cooperation of multiple components ensures the safe operation of the equipment in high-temperature environments.
[0028] The implementation principle of this application embodiment is as follows: by lifting the device with the handle 5, the sliding ring 42 precisely aligns the connecting tube 41 and the positioning tube 45. At this time, the spring 43 restricts the sliding ring 42 from sliding back to its original position, and the positioning ring 46 further prevents the sliding ring 42 from falling off. The ball 47 interacts with the positioning groove 48 to better fix the position of the positioning tube 45, and the sealing ring 44 ensures the sealing of the docking point, thereby achieving accurate detection. When the outer casing 1 is damaged, press the fixing block 341 on the fixing shell 343, and the limiting block 35 will move by sliding, thereby releasing the control of the limiting block 35 by the protective shell 32. At this time, the spring body 33 will automatically act to quickly slide the limiting block 35 back to its original position. Since the sliding of the limiting block is no longer restricted by the protective shell, the detection process becomes faster and more efficient, improving the convenience of maintenance and detection.
