[0041] Embodiment 1

[0042] Please refer to Figures 1 to 3In the first embodiment of the present application, a metallurgical laser centering device 10 is proposed. The metallurgical laser centering device 10 is used for an opening and plugging mechanism 11. The metallurgical laser centering device 10 includes a laser detection mechanism 12 and an indication mechanism; the opening and plugging mechanism 11 includes a blocking block 121, a blocking frame 122 and a first running track 123. The blocking block 121 is arranged on the lower side of the blocking frame 122, and the blocking frame 122 is slidably connected to the first running track 123; specifically, the blocking block 121 is located on the lower side of the blocking frame 122, and is used for physical blocking. Or open the metal discharge port of the furnace; the blocking frame 122 is used to drive the blocking block 121, and the blocking frame 122 is slidably connected to the first running track 123, driving the blocking block 121 to move along the track, so as to achieve the purpose of centering the blocking block 121 on the metal discharge port; the first running track 123 is installed at the smelting site, and the first running track 123 can be close to the furnace and erected above the metal discharge port to ensure the stable movement of the fixed frame and the blocking block 121, and accurately adjust the position to achieve sealing (sealing the eye refers to blocking the metal discharge port) and poking the eye (poking the eye refers to opening the metal discharge port). The laser detection mechanism 12 is arranged on one side of the opening and plugging mechanism 11. The laser detection mechanism 12 includes a laser transmitter 111 and a laser receiver 112, both of which have working directions facing the plugging frame 122. The laser transmitter 111 has a first working direction, and the laser receiver 112 has a second working direction. The first working direction and the second working direction are staggered. At the smelting site, due to the complexity of the environment (such as smoke, light changes, etc.), laser detection may be disturbed, affecting the reliability of the centering result. The staggered working directions of the first working direction and the second working direction can reduce such interference to a certain extent, and improve the adaptability and stability of the device under various environmental conditions; by setting the laser detection mechanism 12 to detect the distance between the plugging frame 122 and the laser detection mechanism 12, it is determined whether the plugging block 121 is centered. The indicating mechanism is electrically connected to the laser detection mechanism 12, and is used to indicate the centering condition; specifically, the indicating mechanism can be installed in a position away from thick smoke and strong light to avoid the operator being in a thick smoke and strong light environment during operation; the indicating mechanism is electrically connected to the laser detection mechanism 12, and based on the received laser measurement data, the indicating mechanism provides the operator with instant feedback on the centering status, indicating whether the blocking block 121 has been accurately centered.

[0043] Specifically, before starting the operation for the first time, the centering target position of the blocking block 121 is preset according to the specifications and position of the metal discharge port; the blocking opening mechanism 11 is controlled to move the blocking block 121 to the preset centering target position of the blocking block 121, and the operator starts the laser detection mechanism 12, the laser transmitter 111 emits laser to the blocking frame 122, and the laser receiver 112 receives the reflected laser and pre-stores the laser detection result (centering distance); when the laser detection result is the centering distance, the indication mechanism feeds back the centering state to the operator, and the operator can perform the sealing or poking operation at this time.

[0044] The present application uses a laser detection mechanism 12 to detect the centering condition, thereby reducing the time that operators need to work in a high temperature and toxic smoke environment, effectively reducing the labor intensity and operational safety risks of operators, and improving the efficiency and accuracy of operations.

[0045] See also Figure 2 In some specific embodiments, the laser detection mechanism 12 further includes a transmitting lens 113 and a receiving lens 114; the transmitting lens 113 is used to focus or shape-adjust the emitted laser beam to improve the collimation and irradiation accuracy of the laser, and the receiving lens 114 is used to collect the reflected laser signal and effectively guide it to the laser receiver 112 to improve the strength and quality of the received signal. The transmitting lens 113 is arranged in the first working direction and is perpendicular to the first working direction; the receiving lens 114 is arranged in the second working direction and is perpendicular to the second working direction; specifically, through the focusing effect of the transmitting lens 113, the laser beam can be transmitted with higher collimation and energy density, and efficient laser transmission can be maintained even in a complex or smoky working environment. The receiving lens 114 effectively improves the receiving strength and stability of the signal by gathering the reflected laser signal, making the laser detection more accurate and reliable. In a smelting site with a complex environment, the use of the transmitting lens 113 and the receiving lens 114 reduces the interference of environmental factors on laser transmission and reception, reduces errors, and improves the adaptability of the laser detection mechanism 12 to external changes.

[0046] In some specific embodiments, the laser detection mechanism 12 further includes a first rotating member and a second rotating member; the laser emitter 111 is disposed on the first rotating member; the laser receiver 112 is disposed on the second rotating member; specifically, the first rotating member is responsible for carrying the laser emitter 111 and allows the laser emitter 111 to be rotated and adjusted when necessary, so that the laser emitter 111 can be accurately aligned with the target area even in a complex or changing working environment. Similar to the first rotating member, the second rotating member carries the laser receiver 112, so that the laser receiver 112 can flexibly adjust its position to receive the laser signal reflected from the blocking frame 122 in the best way.

[0047] Specifically, the first rotating member and the second rotating member are both configured as steering gears, the working end of the first rotating member is threadedly connected to the laser transmitter 111, and the working end of the second rotating member is threadedly connected to the laser receiver 112. The first rotating member drives the laser transmitter 111 to rotate, and the second rotating member drives the laser receiver 112 to rotate, so that the working direction of the laser transmitter 111 and the working direction of the laser receiver 112 rotate closer to or farther from each other, so that when the position of the laser detection mechanism changes due to demand, distance detection can still be achieved.

[0048] See also Figure 4 In some specific embodiments, the laser detection mechanism 12 further includes a protective shell 115, and the laser transmitter 111, the laser receiver 112, the transmitting lens 113 and the receiving lens 114 are all arranged in the protective shell 115; specifically, a solid protective shell 115 is provided around the laser transmitter 111, the laser receiver 112 and the corresponding transmitting lens 113 and the receiving lens 114 to prevent these sensitive components from being physically and chemically damaged in the metallurgical field environment. The protective shell 115 is provided with through holes 116 along the first working direction and the second working direction, and a dustproof net 117 is arranged in the through hole 116; specifically, the through hole 116 provided on the protective shell 115 allows the laser beam to pass freely, ensuring the normal operation of the laser detection system while minimizing the interference with the laser path; the dustproof net 117 is installed inside the through hole 116 to effectively prevent dust, smoke and other particles from entering the protective shell 115, protecting the internal components from contamination, while the through hole 116 allows the laser beam to pass freely.

[0049] In some specific implementations, the indicating mechanism includes an indicator light group, a display screen and a lower computer; the indicator light group is electrically connected to the lower computer; the display screen and the lower computer are integrally arranged. Specifically, the lower computer can be a single chip microcomputer or a PC, and the lower computer serves as the core control unit of the indicating mechanism, and is responsible for processing data from the laser detection mechanism 12, and controlling the display of the indicator light group and the information output of the display screen according to the data.

[0050] In some specific embodiments, the indicator light group includes a centering indicator light, a poking-eye indicator light, and a sealing-eye indicator light; when the blocking block 121 is centered, the centering indicator light is on; when the metal discharge port is opened, the poking-eye indicator light is on; when the metal discharge port is blocked, the sealing-eye indicator light is on. Specifically, the setting of the centering indicator light, the poking-eye indicator light, and the sealing-eye indicator light allows the operator to clearly know the current status and operation steps of the device, reducing the possibility of misoperation; at the same time, it eliminates the need for the operator to repeatedly confirm the position of the blocking block 121, effectively reducing the time the operator works in a high temperature environment and harmful smoke, and significantly reducing the safety risks during the operation.

[0051] Please refer to Figure 1 and Figure 3 In some specific embodiments, a second running track 124 is provided on the lower side of the blocking frame 122, and the second running track 124 is vertically arranged with the first running track 123, and the blocking block 121 is slidably connected to the second running track 124; specifically, the second running track 124 is provided on the lower side of the blocking frame 122, and forms a vertical configuration with the first running track 123, so that the blocking block 121 can slide in two vertical directions, thereby achieving more precise position adjustment. After being centered by the first running track 123, the operator can complete the eye-sealing and eye-poking operations more quickly through the second running track 124. In some specific embodiments, a laser reflector is provided on the side of the blocking frame 122 facing the laser detection mechanism 12; specifically, in order to further improve the measurement accuracy of the laser detection mechanism 12, a laser reflector is provided on the side of the blocking frame 122 facing the laser detection mechanism 12, and the setting of the laser reflector optimizes the laser path, reduces the interference of environmental factors such as smoke, light changes, etc. on the laser signal, and improves the stability and accuracy of the laser detection mechanism 12.

[0052] Embodiment 2

[0053] Please refer to Figures 1 to 3 In the second embodiment of the present application, a metallurgical laser centering device 10 is proposed. In order to improve the anti-interference ability of the laser detection mechanism 12 in a complex smelting environment full of smoke and strong light, the parameters of the laser transmitter 111 and the laser receiver 112 are further limited, and an optical filter is set between the laser receiver 112 and the receiving lens 114;

[0054] Specifically, an optical filter is provided between the laser receiver 112 and the receiving lens 114, and its main function is to filter out light of non-target wavelengths and only allow lasers of specific wavelengths (850nm to 1550nm) to pass through, so as to improve the accuracy of laser reception. The laser transmitter 111 is configured to emit lasers with a wavelength of 850nm to 1550nm. Lasers in this wavelength range have good directivity and penetration, and are suitable for complex industrial environments. The laser wavelength of 850nm to 1550nm can maintain good transmission characteristics under a variety of environmental conditions, including smoke, dust, etc., so that the laser detection mechanism 12 can work effectively in a complex metallurgical environment. In a production environment, application tests are conducted on lasers with wavelengths of 850nm and 1550nm. When the laser wavelength is 850nm, the laser can penetrate thick smoke and irradiate the blocking frame 122, and the laser receiver 112 can receive signals normally; when the laser wavelength is 1550nm, the laser can penetrate thick smoke and irradiate the blocking frame 122, and the laser receiver 112 can receive signals normally. In order to protect the safety of workers, the upper limit of the laser wavelength is set to 1550nm. Even in high-power applications, lasers with a wavelength of 1550nm are not easily absorbed by the cornea, thereby avoiding potential damage to the workers' retina.

[0055] Furthermore, in order to improve the anti-interference capability of the laser detection mechanism 12, the output power range of the laser transmitter 111 is set to 10 mW to 10 W, the pulse width is a short pulse width of nanosecond level, and the repetition rate is kHz level.

It can be seen that the metallurgical equipment is highly safe during operation, effectively reducing the time that operators work in high temperature environments and harmful smoke, and significantly reducing safety risks during operations.

[0058] In summary, the present application provides a metallurgical laser centering device and metallurgical equipment, which are used for an opening and blocking mechanism, wherein the opening and blocking mechanism includes a blocking block, a blocking frame and a first running track, wherein the blocking block is arranged on the lower side of the blocking frame, and the blocking frame is slidably connected to the first running track; the metallurgical laser centering device includes: a laser detection mechanism, which is arranged on one side of the opening and blocking mechanism, and the laser detection mechanism includes a laser transmitter and a laser receiver both of which have working directions toward the blocking frame, and the laser transmitter is used to emit detection light toward the blocking frame; the laser receiver is used to receive detection light reflected by the blocking frame; an indication mechanism, which is electrically connected to the laser detection mechanism and is used to issue a reminder message.
