Description

Technical Field

[0001] This utility model relates to the field of temperature measuring device technology, and in particular to a temperature measuring device for a carbonization chamber. Background Technology

[0002] As a crucial raw material in steel production, precise control of the coke production process is essential for ensuring steel quality and improving production efficiency. This process begins with the rational blending of different types of coal to achieve ideal coke quality and yield. After mixing, these coals are fed into a carbonization chamber, where they undergo high-temperature coking to form coke with specific physical and chemical properties.

[0003] Therefore, the temperature of the coke inside the carbonization chamber is crucial. Thermocouples are used to provide feedback on the internal temperature. However, thermocouples are mostly fixed and can only reflect the local coke temperature directly, not the overall temperature distribution inside the carbonization chamber. To address this, we propose a carbonization chamber temperature measuring device to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a carbonization chamber temperature measuring device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbonization chamber temperature measuring device, comprising a carbonization chamber, a cone, a motor, a temperature sensor, a support plate, and a support base. A temperature sensor is installed at the rear end of the carbonization chamber, a thermocouple is installed inside the carbonization chamber, a support plate is installed at the upper end of the cone, a motor is installed at one end of the carbonization chamber, a screw is rotatably mounted inside the carbonization chamber at the motor output end, symmetrically distributed threaded sliders are threaded onto the outer wall of the screw, a support base is installed at the lower end of the threaded sliders, a spring is connected between the support base and the support plate, multiple sets of symmetrically distributed springs are installed at the lower end of the carbonization chamber, a cone plate is installed at the lower end of each spring, and a hydraulic rod with a telescopic end slidably mounted on the inner wall of the upper end of the carbonization chamber is installed at the upper end of the carbonization chamber.

[0006] When using a carbonization chamber temperature measuring device in this solution, the hydraulic rod drives the telescopic end to pressurize the cone plate, while the second spring is stretched. The lower end of the cone plate squeezes the support plate, and the support plate moves away, squeezing the first spring. The first spring contracts, and the thermocouple is exposed in the coke to monitor the temperature of the coke. After the hydraulic rod lifts, the cone plate loses the compression, and the second spring, through its own elasticity, pulls the cone plate to lift. The cone plate returns to its original position and is misaligned with the support plate, located above the support plate. At the same time, the support plate loses the compression, and the second spring is contacted by the applied pressure, pushing the support plate to its original position through its own elasticity.

[0007] The motor operates, driving the screw to rotate. The screw pushes the threaded slider. Because the threaded slider is guided by the guide rod, the threaded slider moves laterally, causing the cone and its internal thermocouple to move laterally. The hydraulic rod one is equidistant from the cone plate. When the position of the cone corresponds to other cone plates, the above operation is repeated to detect coke at different positions. When the temperature sensor is installed, it is connected to the mounting port through the mounting plate. The fixed rod of the rotating installation is rotated to one side of the mounting plate. The hydraulic rod two drives the fixed rod to press and hold the mounting plate, thus pressing and fixing the mounting plate.

[0008] Preferably, a guide rail is provided on the upper inner wall of the carbonization chamber, and the upper end of the threaded slider is slidably mounted on the outer wall of the guide rail. The threaded slider is slidably supported by the guide rail, and thus the screw applies a compressive force to the threaded slider when it rotates.

[0009] Preferably, the support base has a through hole inside, and one end of the support plate is provided with a guide rod that is slidably inserted into the through hole and located inside the spring. The support plate moves in the through hole inside the support base through the guide rod, thereby guiding the spring and limiting its extension and retraction.

[0010] Preferably, the width of the lower outer wall of the cone plate gradually increases from bottom to top, and the telescopic end of the hydraulic rod is located directly above the cone plate. When the cone plate descends, it gradually applies a compressive force to the support plate; when the hydraulic rod operates, the telescopic end applies a compressive force to the upper part of the cone plate.

[0011] Preferably, multiple sets of symmetrically distributed sliding sleeves are embedded in the upper inner wall of the carbonization chamber, and a guide rod II is provided at the upper end of the conical plate, located inside the second spring and slidably installed inside the second sliding sleeve. The guide rod II is slidably supported by the sliding sleeve, and is slidably guided inside the carbonization chamber by the sliding sleeve, thereby guiding the extension and retraction of the second spring II, preventing the second spring II from deviating outward, and limiting the extension and retraction of the second spring II.

[0012] Preferably, the conical tubes are symmetrically distributed outside the thermocouple. When the thermocouple moves laterally, the conical tubes protect the thermocouple, preventing it from directly compressing the coke and thus protecting the thermocouple.

[0013] Preferably, a terminal is connected between the thermocouple and the temperature sensor, and equidistant support rods are arranged inside the upper part of the carbonization chamber, with the terminal located at the upper end of the support rods. The terminal connects the thermocouple and the temperature sensor together, and the support rods support the lower end of the terminal to prevent it from falling into the coke, thus protecting the terminal.

[0014] Preferably, the carbonization chamber has an installation port at its rear end, the wiring terminal is located inside the installation port, and the temperature sensor is fitted with a mounting plate that fits into the installation port. Hydraulic rods are provided at each of the four corners of the rear end of the mounting plate. A fixing rod is rotatably mounted on the telescopic end of each hydraulic rod, and one end of the fixing rod presses against the outer wall of the mounting plate. The temperature sensor's wiring terminal is arranged inside the carbonization chamber through the installation port, and the hydraulic rods drive the fixing rods to press against the four corners of the mounting plate.

[0015] Preferably, a guide plate is provided at the rear end of the carbonization chamber, and a guide block is provided at the lower end of the mounting plate, which is slidably mounted on the upper end of the guide plate. The mounting plate is slidably supported on the guide plate by the guide block, which positions the temperature sensor during installation and supports the bottom, facilitating the installation and fixation of the mounting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model provides a thermocouple connected to a temperature sensor inside the carbonization chamber to reflect the temperature of the coke at a specified location inside the carbonization chamber. The thermocouple is inserted into the coke through an elastic element and a lateral moving element, and the temperature at different locations inside the coke is detected, thus comprehensively reflecting the temperature distribution inside the entire carbonization chamber.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, the present invention proposes a carbonization chamber temperature measuring device, including a carbonization chamber 1, a cone 3, a motor 5, a temperature sensor 7, a support plate 9, and a support base 15. The temperature sensor 7 is installed at the rear end of the carbonization chamber 1, and a thermocouple 17 is installed inside the carbonization chamber 1. The support plate 9 is installed at the upper end of the cone 3. The motor 5 is installed at one end of the carbonization chamber 1. The output end of the motor 5 is provided with a screw 4 rotatably installed inside the carbonization chamber 1. The screw 4 has symmetrically distributed threaded sliders 14 threaded on its outer wall. The support base 15 is installed at the lower end of the threaded sliders 14. A spring 18 is connected between the support base 15 and the support plate 9. Multiple sets of symmetrically distributed springs 21 are provided at the lower end of the carbonization chamber 1. A cone plate 8 is provided at the lower end of the springs 21. A hydraulic rod 2 with its telescopic end slidably installed on the inner wall of the upper end of the carbonization chamber 1 is provided at the upper end of the carbonization chamber 1.

[0026] A guide rail 13 is provided on the upper inner wall of the carbonization chamber 1, and the upper end of the threaded slider 14 is slidably installed on the outer wall of the guide rail 13.

[0027] The support base 15 has a through hole 16 inside, and one end of the support plate 9 is provided with a guide rod 19 that is slidably inserted into the through hole 16 and located inside the spring 18.

[0028] The width of the lower outer wall of the cone plate 8 gradually increases from bottom to top, and the telescopic end of the hydraulic rod 2 is located directly above the cone plate 8.

[0029] Multiple sets of symmetrically distributed sliding sleeves 22 are embedded in the inner wall of the upper end of the carbonization chamber 1, and a guide rod 20 located inside the spring 21 and slidably installed inside the sliding sleeve 22 is provided on the upper end of the cone plate 8.

[0030] Based on the implementation steps of Example 1: Hydraulic rod 2 is operated, causing cone plate 8 to press against support plate 9. Spring 21 and spring 18 are pulled up accordingly, exposing thermocouple 17 to the coke for temperature monitoring. After hydraulic rod 2 is raised, cone plate 8 loses pressure. Spring 21 lifts cone plate 8 through its own elasticity, causing support plate 9 to reset and release pressure on spring 18. Motor 5 starts, driving screw 4 to push threaded slider 14, causing cone 3 and thermocouple 17 to move laterally to a new position for temperature monitoring of another coke location. This achieves multi-point temperature monitoring of coke, avoiding the fixed installation of thermocouple 17 which can only reflect local coke temperature. By monitoring coke temperature at multiple points, the temperature distribution inside the entire carbonization chamber 1 is comprehensively reflected.

[0031] like Figures 1-5 As shown, compared with Embodiment 1, the carbonization chamber temperature measuring device proposed in this utility model further includes: the cone cylinders 3 are symmetrically distributed outside the thermocouple 17.

[0032] A terminal 12 is connected between the thermocouple 17 and the temperature sensor 7. Equally spaced support rods 11 are provided inside the upper end of the carbonization chamber 1, and the terminal 12 is located at the upper end of the support rods 11.

[0033] The carbonization chamber 1 has an installation port 10 at the rear end. The wiring terminal 12 is located inside the installation port 10. The temperature sensor 7 is sleeved on the outer wall and fitted with an installation plate 6 that fits into the installation port 10. Hydraulic rods 25 are provided at the four corners of the rear end of the installation plate 6. A fixing rod 26 is rotatably installed at the telescopic end of the hydraulic rod 25, and one end of the fixing rod 26 is pressed against the outer wall of the installation plate 6.

[0034] A guide plate 23 is provided at the rear end of the carbonization chamber 1, and a guide block 24 is slidably installed on the upper end of the guide plate 23 at the lower end of the mounting plate 6.

[0035] In this embodiment, it is worth noting that the outer wall of the terminal 12 is fitted with a material with excellent high-temperature corrosion resistance and good insulation performance. Graphite material can be selected, which has corrosion resistance, good thermal conductivity, and is suitable for electrical terminal 12 protection in high-temperature environments. The temperature sensor 7 is connected to the carbonization chamber 1 through the mounting plate 6, and the four corners of the mounting plate 6 are pressed by the fixing rod 26, avoiding bolt fixing or welding to the outer wall of the carbonization chamber 1. This realizes convenient installation and disassembly of the mounting plate 6, and convenient maintenance when the temperature sensor 7 is damaged.

[0036] The above specific embodiments are merely several preferred embodiments of this utility model.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
