Description

Technical Field

[0001] This utility model relates to the field of silicon carbide rod technology, and in particular to a detection device for silicon carbide rods. Background Technology

[0002] Silicon carbide rods are commonly used in existing sintering furnaces. When purchasing silicon carbide rods, cold resistance is usually used as the acceptance standard. However, the industry uses hot resistance as the standard to determine whether they have reached the scrapping standard. This makes it impossible for industry personnel to determine whether silicon carbide rods have reached the scrapping standard based on their cold resistance at the time of purchase. In other words, when the hot resistance of silicon carbide rods cannot be determined, and the sintering furnace temperature is abnormal, maintenance personnel usually have to replace all silicon carbide rods when dealing with the abnormal temperature situation. This leads to higher maintenance costs and the risk of burns during the replacement of silicon carbide rods.

[0003] In view of the above, the designer of this utility model designed this utility model. Utility Model Content

[0004] The purpose of this invention is to provide a detection device for silicon carbide rods, so that maintenance personnel can promptly obtain the temperature and thermal resistance of the silicon carbide rods, thereby reducing maintenance costs and preventing burns during the replacement of silicon carbide rods.

[0005] To achieve the above objectives, the present invention adopts the following solution: A detection device for silicon carbide rods includes: a silicon carbide rod, an electricity meter, a display control device, a temperature controller, a temperature sensor, an input power module, and a regulator. The input power module is electrically connected to the silicon carbide rod and the regulator. The electricity meter is electrically connected to the silicon carbide rod. The electricity meter is communicatively connected to the display control device. The display control device is communicatively connected to the temperature controller. The temperature controller is electrically connected to the temperature sensor and the regulator. The temperature sensor rests against the outer wall of the silicon carbide rod.

[0006] In some embodiments, a detection device for a silicon carbide rod further includes a regulator-start power module, wherein the regulator is electrically connected to the regulator-start power module.

[0007] In some embodiments, the temperature sensor is a thermocouple.

[0008] In some embodiments, the thermocouple is a retractable thermocouple.

[0009] In some embodiments, a silicon carbide rod detection device further includes a ceramic sleeve, heat insulation cotton, and a metal tube. The ceramic sleeve is housed in the metal tube, the heat insulation cotton is housed between the ceramic sleeve and the metal tube, the silicon carbide rod is housed inside the ceramic sleeve, and the temperature sensor extends into the ceramic sleeve.

[0010] In some embodiments, a support is provided at the bottom of the metal tube.

[0011] In some embodiments, the top of the metal tube is provided with a through pipe, the temperature sensor extends into the through pipe, and the through pipe communicates with the interior of the ceramic sleeve.

[0012] In some embodiments, at least one sensor fixing bolt is screwed onto the left and right sides of the through pipe, and the end of the sensor fixing bolt abuts against the outer wall of the temperature sensor.

[0013] In some embodiments, the sensor fixing bolts are arranged at vertical intervals.

[0014] At least one ceramic sleeve fixing bolt is screwed onto the end of each metal tube, and the end of the ceramic sleeve fixing bolt abuts against the outer wall of the ceramic sleeve.

[0015] As can be seen from the above technical solution, this utility model, through the coordinated structural design of a silicon carbide rod, an electricity meter, a display control device, a temperature controller, a temperature sensor, an input power module, and a regulator, achieves the following: In terms of temperature detection, the temperature sensor is electrically connected to the temperature controller, transmitting the temperature signal of the silicon carbide rod to the temperature controller in real time. The temperature controller, in turn, is communicatively connected to the display control device, sending the received temperature information to it. This allows maintenance personnel to promptly obtain the temperature of the silicon carbide rod from the display control device. Regarding the hot resistance value, since the electricity meter is electrically connected to the silicon carbide rod, it can monitor the voltage, current, and other electrical parameters of the silicon carbide rod in real time. The electricity meter, communicatively connected to the display control device, transmits these electrical parameters to the display control device. The display control device calculates the electrical parameters according to Ohm's law to obtain the hot resistance value of the silicon carbide rod. Maintenance personnel can then promptly obtain the hot resistance value of the silicon carbide rod from the display control device. Based on this timely temperature information, maintenance personnel can choose to replace the silicon carbide rod only after its temperature has dropped to a safe range, avoiding burns caused by high temperatures. Meanwhile, this invention can control the current flowing through the silicon carbide rod via a regulator to determine whether the relationship between the temperature of the silicon carbide rod and its hot resistance is abnormal. By checking whether the relationship between the hot resistance and the temperature of the silicon carbide rod is abnormal, the performance status of the silicon carbide rod can be judged. When the relationship between the hot resistance and the temperature of the silicon carbide rod is abnormal, it indicates that the silicon carbide rod may be faulty. Replacing it at this time can avoid unnecessary premature replacement, reduce the replacement frequency, and thus reduce maintenance costs. When the silicon carbide rod is indeed unable to work properly, timely replacement can avoid greater losses caused by the fault and further control maintenance costs. Attached Figure Description

[0027] Reference Figure 1 As shown, this utility model discloses a detection device for silicon carbide rods, including: a silicon carbide rod 1, an energy meter 2, a display control device 3, a temperature controller 4, a temperature sensor, an input power module 6, and a regulator 7. The input power module 6 is electrically connected to the silicon carbide rod 1 and the regulator 7. The energy meter 2 is electrically connected to the silicon carbide rod 1 and is communicatively connected to the display control device 3. The display control device 3 is communicatively connected to the temperature controller 4. The temperature controller 4 is electrically connected to the temperature sensor and the regulator 7. The temperature sensor is abutted against the outer wall of the silicon carbide rod 1. The display control device 3 can be a touch screen. The energy meter 2 and the temperature controller 4 can communicate with the display control device 3 via 485 communication. The voltage of the input power module 6 can be 380V. The regulator 7 can provide a 4~20mA start signal to the temperature controller 4.

[0028] Therefore, this utility model, through the coordinated structural design of silicon carbide rod 1, electricity meter 2, display control device 3, temperature controller 4, temperature sensor, input power module 6, and regulator 7, achieves the following in terms of temperature detection: the temperature sensor is electrically connected to the temperature controller 4, which can transmit the temperature signal of silicon carbide rod 1 to the temperature controller 4 in real time; the temperature controller 4 is communicatively connected to the display control device 3, which can send the received temperature information to the display control device 3. Thus, maintenance personnel can promptly obtain the temperature of silicon carbide rod 1 from the display control device 3. Regarding the hot resistance value, since the electricity meter 2... Electrically connected to silicon carbide rod 1, the voltage, current and other electrical parameters of silicon carbide rod 1 can be monitored in real time. The energy meter 2 is communicatively connected to the display control device 3, which transmits these electrical parameters to the display control device 3. The display control device 3 calculates the electrical parameters according to Ohm's law to obtain the hot resistance value of silicon carbide rod 1. Maintenance personnel can then obtain the hot resistance value of silicon carbide rod 1 from the display control device 3 in a timely manner. Based on the timely knowledge of the temperature of silicon carbide rod 1, maintenance personnel can choose to replace the silicon carbide rod 1 after the temperature drops to a safe range, avoiding burns caused by high temperature. Meanwhile, this invention can control the current through the silicon carbide rod 1 using the regulator 7 to determine whether the relationship between the temperature of the silicon carbide rod 1 and its hot resistance is abnormal. The performance status of the silicon carbide rod 1 can be judged by whether the relationship between the hot resistance and the temperature of the silicon carbide rod 1 is abnormal. When the relationship between the hot resistance and the temperature of the silicon carbide rod 1 is abnormal, it indicates that the silicon carbide rod 1 may be faulty. Replacing it at this time can avoid unnecessary premature replacement, reduce the replacement frequency, and thus reduce maintenance costs. When the silicon carbide rod 1 is indeed unable to work properly, timely replacement can avoid greater losses caused by the fault and further control maintenance costs.

[0029] The display control device 3 of this utility model can output real-time monitored voltage, current and temperature, as well as output corresponding hot resistance values. It can record hot resistance data and output hot resistance curves in real time by setting a target temperature.

[0030] In some embodiments, the present invention may further include a regulator startup power supply module 71, wherein the regulator 7 is electrically connected to the regulator startup power supply module 71, wherein the voltage of the regulator startup power supply module 71 can be 220V, thereby using the regulator startup power supply module 71 as an independent power supply unit to provide the regulator 7 with stable startup power and continuous operating power.

[0032] In some embodiments, please refer to Figures 2 to 7 As shown, this utility model may also include a ceramic sleeve 81, heat insulation cotton 82, and a metal tube 83. The ceramic sleeve 81 is housed in the metal tube 83, the heat insulation cotton 82 is housed between the ceramic sleeve 81 and the metal tube 83, the silicon carbide rod 1 is housed in the ceramic sleeve 81, and the temperature sensor extends into the ceramic sleeve 81, which helps the temperature sensor to measure temperature accurately. This utility model uses the ceramic sleeve 81 to protect the silicon carbide rod 1, and uses the heat insulation cotton 82 to enhance heat insulation. The metal tube 83 provides mechanical protection, thereby extending the life of the silicon carbide rod 1, ensuring the accuracy of temperature measurement, preventing burns, and reducing energy consumption.

[0033] The metal tube 83 can be a 304 stainless steel tube, which can be a stainless steel tube with a length of 2m and a cross-sectional diameter of 16cm. The ceramic sleeve 81 can be 2.24m long. The silicon carbide rod 1 can be fixed by a fixing sleeve 11 made of alumina ceramic fiber.

[0034] In some embodiments, in order to support the metal tube 83, a bracket 84 is provided at the bottom of the metal tube 83, and the bracket 84 is provided on the left and right sides of the metal tube 83 to form an open "eight" shape.

[0035] Furthermore, to facilitate the insertion of the temperature sensor into the ceramic sleeve 81 and to protect the temperature sensor, a through-tube 831 is provided at the top of the metal tube 83. The temperature sensor extends into the through-tube 831, and the through-tube 831 connects to the interior of the ceramic sleeve 81.

The figure illustrates an example with three through-tubes 831, but this is not a limitation.

[0036] Secondly, at least one sensor fixing bolt 832 is screwed onto the left and right sides of the through pipe 831 respectively. The end of the sensor fixing bolt 832 abuts against the outer wall of the temperature sensor, so that the position of the temperature sensor in the through pipe 831 can be adjusted by using the sensor fixing bolt 832 to make it centrally positioned and reduce temperature measurement error.

[0037] In this embodiment, the sensor fixing bolts 832 are arranged at vertical intervals to prevent the temperature sensor from shaking.

[0038] In addition, at least one ceramic sleeve fixing bolt 833 is screwed into each end of the metal tube 83, and the end of the ceramic sleeve fixing bolt 833 abuts against the outer wall of the ceramic sleeve 81; thus, the position of the ceramic sleeve 81 can be adjusted by the depth to which the ceramic sleeve fixing bolt 833 is screwed into the metal tube 83.
