Furnace temperature measuring device for high-temperature furnace

Abstract

This utility model discloses a furnace temperature measuring device for a high-temperature furnace, relating to the field of furnace temperature measurement technology. It includes a base with equally spaced threaded mounting holes on the top outer wall. A control component is located in the middle of the top outer wall. In this utility model, when measuring the furnace temperature, a first electric telescopic rod drives a connecting rod and a temperature measuring head to descend. The temperature measuring head and connecting rod extend into the furnace through a detection hole to measure the temperature. After measurement, the temperature measuring head detaches from the furnace. During the ascent of the temperature measuring head, a cleaning pad inside a cleaning sleeve wipes the connecting rod and the outer wall of the temperature measuring head, removing any high-temperature solution adhering to them. This ensures the cleanliness of the connecting rod and the temperature measuring head, preventing the solution from solidifying on them and forming a hard, difficult-to-clean shell. This avoids the temperature measuring head being covered, affecting the accuracy of subsequent measurements, and also prevents the high-temperature solution from continuously damaging the temperature measuring head and affecting its normal operation.

Description

Technical Field

[0001] This utility model relates to the field of furnace temperature measurement technology, and in particular to a furnace temperature measuring device for high-temperature furnaces. Background Technology

[0002] A high-temperature furnace is an industrial device that melts materials or induces chemical reactions in a high-temperature environment. It is widely used in metallurgy, casting, and other fields. Its main principle is to melt solid raw materials or induce chemical reactions at high temperatures. For example, in steel smelting, iron ore and coke react at high temperatures in the furnace, reducing iron and removing impurities, ultimately producing high-quality steel. High-temperature furnaces are mainly used in metal smelting (such as zinc alloys), glass melting, and ceramic manufacturing, achieving material purification or shaping through high temperatures. The main characteristics of a high-temperature furnace include: lightweight equipment, fast heating speed, and high efficiency; exceptionally energy-saving, consuming 60% less electricity than a high-frequency vacuum tube furnace for the same load; multiple protection functions such as overcurrent, overvoltage, and overheat protection; simple operation and convenient installation; suitable for various applications requiring metal heating. During operation, temperature measurement is necessary, requiring the use of a temperature measuring device.

[0003] However, existing high-temperature furnace temperature measuring devices have certain shortcomings: First, when existing furnace temperature measuring devices measure furnace temperature, the high-temperature solution on the inner wall of the furnace may adhere to the surface of the temperature measuring component. After these solutions solidify, they will form a solid shell on the surface of the temperature measuring device. These shells are difficult to clean, and long-term adhesion will affect the accuracy of temperature measurement. Secondly, after measuring the furnace temperature, the existing temperature measuring device requires the operator to manually remove the solution adhering to the outer wall of the temperature measuring component. Since the solution temperature is high, manual removal poses a certain risk. Utility Model Content

[0004] The purpose of this application is to provide a furnace temperature measuring device for a high-temperature furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a furnace temperature measuring device for a high-temperature furnace, comprising a base, with equally spaced threaded mounting holes on the top outer wall of the base, a control component positioned in the middle of the top outer wall of the base, a measuring component and a sealing component respectively positioned at both ends of the control component, the measuring component and the sealing component being adapted to the control component, the measuring component comprising a sleeve, a mounting hole on the top outer wall of the sleeve, a first electric telescopic rod mounted on the inner wall of the mounting hole, the first electric telescopic rod being adapted to the sleeve, a connecting rod being bolted to the end of the first electric telescopic rod, the connecting rod being cylindrical, the diameter of the connecting rod being smaller than the diameter of the sleeve, the connecting rod being made of tungsten metal, a temperature measuring head being provided at the end of the connecting rod, the temperature measuring head having the same diameter as the connecting rod, a cleaning sleeve being mounted at the end of the sleeve, a cleaning pad adapted to the cleaning sleeve being provided on the inner wall of the cleaning sleeve, the cleaning pad being made of phenyl silicone rubber, the temperature measuring head being connected to a controller via a wireless network, and the controller being connected to a display via a wireless network.

[0006] Preferably, the top of the cleaning sleeve is provided with a connecting groove, the outer wall of the connecting groove is provided with equally spaced external threads, and the inner wall of the bottom of the sleeve is provided with an internal thread that matches the external threads.

[0007] Preferably, the control component includes a support rod welded to the middle of the outer wall of the top of the base, a control cylinder welded to the top of the support rod, a control disk rotatably mounted on the top of the control cylinder, and mounting disks adapted to the control disk on both sides of the outer wall of the control disk, with one side of the mounting disk connected to the sleeve.

[0008] Preferably, the control cylinder has a drive groove inside, a drive motor is installed on the inner wall of the drive groove, and the output shaft of the drive motor is connected to the control disk.

[0009] Preferably, the enclosure assembly includes a second electric telescopic rod installed at the bottom of a mounting plate on one side, and a sealing plate is bolted to the end of the second electric telescopic rod. The outer wall of the sealing plate is covered with a matching sealing gasket, which is made of phenyl silicone rubber.

[0010] Preferably, an operation hole is provided at one end of the top outer wall of the base. The operation hole is adapted to the measuring component and the sealing component respectively. The size of the operation hole is larger than the size of the sealing plate. An anti-slip pad adapted to the bottom outer wall of the base is provided. The thickness of the anti-slip pad is less than the thickness of the base. The anti-slip pad is made of phenyl silicone rubber.

[0011] Preferably, a power supply battery is installed on both the outer wall of the sleeve and the top outer wall of the mounting plate on one side, and the power supply battery is adapted to the power-consuming component.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, during operation, the base is fixed on the furnace cover to ensure that both the measuring component and the sealing component correspond to the detection holes on the furnace cover. When furnace temperature measurement is not required, the sealing component closes the detection holes, and the sleeve protects the temperature measuring head. When furnace temperature measurement is required, the control component moves the sealing component and the detection component to switch positions. At this time, the first electric telescopic rod drives the connecting rod and the temperature measuring head to descend. The temperature measuring head and the connecting rod extend into the furnace through the detection holes to measure the temperature. The data detected by the temperature measuring head is transmitted to the display for display. After the measurement is completed, the temperature measuring head rises and detaches from the furnace. During the rising process of the temperature measuring head, the cleaning pad inside the cleaning sleeve is cleaned. Wipe the connecting rod and the outer wall of the temperature measuring head to remove the high-temperature solution adhering to them, ensuring their cleanliness and preventing the solution from solidifying and forming a hard shell that is difficult to clean. This avoids the temperature measuring head being covered, which could affect the accuracy of subsequent measurements, and also prevents the high-temperature solution from continuously damaging the temperature measuring head and affecting its normal operation. The cleaning sleeve and the sleeve are rotatably connected for easy replacement. Compared to traditional temperature measuring devices, after temperature measurement, the temperature measuring head is automatically wiped by a high-temperature resistant cleaning pad, preventing the solution from solidifying and forming a hard shell that could affect the normal operation of the temperature measuring head, and also preventing the temperature measuring head from being burned by high temperatures for a long time, thus affecting its service life.

[0013] 2. In this utility model, when the measuring component and the sealing component are working, the drive motor drives the control disk to rotate, which in turn drives the mounting disk to rotate, thereby changing the position of the sealing component and the measuring component. When it is not necessary to measure the furnace temperature, the sealing component aligns with the furnace detection port and seals it. When it is necessary to measure the furnace temperature, the positions of the two are switched, and the detection component enters the furnace to measure the temperature. The operation is more convenient and can be operated remotely by humans. The measurement is more convenient and safer. When it is not necessary to measure the furnace temperature, the second electric telescopic rod drives the sealing plate to descend. The sealing plate is inserted into the detection hole on the furnace cover to block it, improves the airtightness, and prevents heat or pressure leakage when the furnace is working. The sealing gasket further improves the airtightness and makes it safer to use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Example: Reference Figure 1-4 The device shown is a furnace temperature measuring device for a high-temperature furnace, comprising a base 1. The outer top wall of the base 1 has equally spaced threaded mounting holes. A control component is positioned in the middle of the outer top wall of the base 1. A measuring component and a sealing component are respectively located at both ends of the control component, both of which are adapted to the control component. The measuring component includes a sleeve 2. The outer top wall of the sleeve 2 has mounting holes. A first electric telescopic rod 3 is mounted on the inner wall of the mounting holes, adapting to the sleeve 2. A connecting rod 4, which is cylindrical, is bolted to the end of the first electric telescopic rod 3. The diameter of the connecting rod 4 is smaller than that of the sleeve 2. The connecting rod 4 is made of tungsten metal. A temperature measuring head 5 is provided at the end of the connecting rod 4. The diameter of the temperature measuring head 5 is the same as that of the connecting rod 4. A cleaning sleeve 6 is installed at the end of the sleeve 2. A cleaning pad 7 that matches the cleaning sleeve 6 is provided on the inner wall of the cleaning sleeve 6. The cleaning pad 7 is made of phenyl silicone rubber. The temperature measuring head 5 is connected to a controller via a wireless network. The controller is connected to a display 9 via a wireless network. A connecting groove 8 is provided at the top of the cleaning sleeve 6. External threads that are evenly distributed are provided on the outer wall of the connecting groove 8. Internal threads that match the external threads are provided on the inner wall of the bottom of the sleeve 2.

[0019] With the above structure: During operation, the base 1 is fixed on the furnace cover, ensuring that both the measuring component and the sealing component correspond to the detection holes on the furnace cover. When furnace temperature measurement is not required, the sealing component closes the detection holes, and the sleeve 2 protects the temperature measuring head 5. When furnace temperature measurement is required, the control component moves the sealing component and the detection component to switch positions. At this time, the first electric telescopic rod 3 drives the connecting rod 4 and the temperature measuring head 5 to descend. The temperature measuring head 5 and the connecting rod 4 extend into the furnace through the detection holes to measure the temperature. The data detected by the temperature measuring head 5 is transmitted to the display 9 for display. After the measurement is completed, the temperature measuring head 5 rises and detaches from the furnace. During the rising process of the temperature measuring head 5, the cleaning pad 7 inside the cleaning sleeve 6 protects the connecting rod 5. The rod 4 and the outer wall of the temperature measuring head 5 are wiped to remove the high-temperature solution adhering to the connecting rod 4 and the temperature measuring head 5, ensuring the cleanliness of the connecting rod 4 and the temperature measuring head 5. This prevents the solution from solidifying on the connecting rod 4 and the temperature measuring head 5 to form a hard shell that is difficult to clean, avoiding the temperature measuring head 5 being covered and affecting the accuracy of subsequent measurements. At the same time, it prevents the high-temperature solution from continuously damaging the temperature measuring head 5 and affecting its normal operation. The cleaning sleeve 6 is rotatably connected to the sleeve 2 for easy replacement. Compared with traditional temperature measuring devices, after the temperature measurement is completed, the high-temperature resistant cleaning pad 7 automatically wipes the temperature measuring head 5, preventing the solution from solidifying and forming a hard shell that affects the normal operation of the temperature measuring head 5, and also preventing the temperature measuring head 5 from being burned by high temperature for a long time, thus affecting its service life.

[0020] like Figure 2 As shown, the control component includes a support rod 10 welded to the middle of the top outer wall of the base 1. A control cylinder 11 is welded to the top of the support rod 10. A control disk 12 is rotatably mounted on the top of the control cylinder 11. Mounting disks are provided on both sides of the outer wall of the control disk 12. One mounting disk is connected to the sleeve 2. A drive groove is opened inside the control cylinder 11. A drive motor 13 is installed on the inner wall of the drive groove. The output shaft of the drive motor 13 is connected to the control disk 12. When the measuring component and the sealing component are working, the drive motor 13 drives the control disk 12 to rotate, thereby causing the mounting disk to rotate and changing the position of the sealing component and the measuring component. When it is not necessary to measure the furnace temperature, the sealing component aligns with the furnace detection port and closes it. When it is necessary to measure the furnace temperature, the positions of the two are switched, and the detection component enters the furnace to measure the temperature. The operation is more convenient and can be operated remotely by humans, making the measurement more convenient and safer.

[0021] like Figure 2As shown, the sealing assembly includes a second electric telescopic rod 14 installed at the bottom of one side of the mounting plate. A sealing plate 15 is bolted to the end of the second electric telescopic rod 14. The outer wall of the sealing plate 15 is covered with a matching sealing gasket 16. The sealing gasket 16 is made of phenyl silicone rubber. When furnace temperature measurement is not required, the second electric telescopic rod 14 drives the sealing plate 15 to descend, and the sealing plate 15 is inserted into the detection hole on the furnace cover to block it, thereby improving the airtightness and preventing heat or pressure leakage during furnace operation. The sealing gasket 16 further improves the airtightness and makes the use safer.

[0022] like Figure 1 As shown, an operation hole 17 is provided at one end of the top outer wall of the base 1. The operation hole 17 is adapted to the measuring component and the sealing component respectively. The size of the operation hole 17 is larger than the size of the sealing plate 15. An anti-slip pad 18 adapted to it is provided on the bottom outer wall of the base 1. The thickness of the anti-slip pad 18 is less than the thickness of the base 1. The anti-slip pad 18 is made of phenyl silicone rubber. The operation hole 17 corresponds to the detection hole on the furnace cover, which facilitates the operation of the measuring component and the sealing component.

[0023] like Figure 1 As shown, power supply batteries 19 are installed on the outer wall of the sleeve 2 and the top outer wall of the mounting plate on one side. The power supply batteries 19 are adapted to the electrical components and supply power to the first electric telescopic rod 3 and the second electric telescopic rod 14 to ensure that they work normally.

[0024] The working principle of this practical application is as follows: During operation, the base 1 is fixed on the furnace cover, ensuring that both the measuring component and the sealing component correspond to the detection holes on the furnace cover. When furnace temperature measurement is not required, the sealing component closes the detection holes, and the sleeve 2 protects the temperature measuring head 5. When furnace temperature measurement is required, the control component moves the sealing component and the detection component to switch positions. At this time, the first electric telescopic rod 3 drives the connecting rod 4 and the temperature measuring head 5 to descend. The temperature measuring head 5 and the connecting rod 4 extend into the furnace through the detection holes to measure the temperature. The data detected by the temperature measuring head 5 is transmitted to the display 9 for display. After the measurement is completed, the temperature measuring head 5 rises and detaches from the furnace. During the rising process of the temperature measuring head 5, the cleaning pad 7 inside the cleaning sleeve 6 protects the connecting rod 4 and the... The outer wall of the temperature measuring head 5 is wiped to remove the high-temperature solution adhering to the connecting rod 4 and the temperature measuring head 5, ensuring the cleanliness of the connecting rod 4 and the temperature measuring head 5. This prevents the solution from solidifying on the connecting rod 4 and the temperature measuring head 5 to form a hard shell that is difficult to clean, thus avoiding the temperature measuring head 5 being covered and affecting the accuracy of subsequent measurements. At the same time, it prevents the high-temperature solution from continuously damaging the temperature measuring head 5 and affecting its normal operation. The cleaning sleeve 6 is rotatably connected to the sleeve 2 for easy replacement. Compared with traditional temperature measuring devices, after the temperature measurement is completed, the temperature measuring head 5 is automatically wiped by the high-temperature resistant cleaning pad 7, preventing the solution from solidifying and forming a hard shell that affects the normal operation of the temperature measuring head 5, and also preventing the temperature measuring head 5 from being burned by high temperature for a long time, thus affecting its service life. When the measuring component and the sealing component are working, the drive motor 13 drives the control panel 12 to rotate, which in turn drives the mounting plate to rotate, thereby changing the position of the sealing component and the measuring component. When it is not necessary to measure the furnace temperature, the sealing component aligns with the furnace detection port and seals it. When it is necessary to measure the furnace temperature, the positions of the two are switched, and the detection component enters the furnace to measure the temperature. The operation is more convenient and can be performed remotely by humans. The measurement is more convenient and safer.
