Abstract
Description
Technical Field
[0001] The present application relates to the technical field of thermocouple installation depth measurement, and in particular to a gasifier thermocouple installation depth measurement device. Background Art
[0002] Monitoring the internal temperature of the gasifier by thermocouples can effectively guide the process production. At present, the installation length of the thermocouple of the gasifier is usually flush with the inner wall of the furnace bricks facing the fire surface of the gasifier. However, in actual use, the refractory bricks facing the fire surface inside the gasifier furnace will continue to thin during the operation of the gasifier, which makes the thermocouple easily damaged during the operation of the gasifier, causing the service life of the thermocouple of the gasifier to fail to meet the requirements. Based on this, after adjusting the installation length of the thermocouple, the service life of the high-temperature thermocouple is observed. After the gasifier is shut down, the installation length of the thermocouple is adjusted again according to the wear of the furnace wall. Through repeated adjustments and observations, the optimal installation length and service life of the thermocouple can be determined.
[0003] However, the gasifier thermocouple is usually installed in a thermocouple mounting hole that passes through the furnace wall and the refractory brick. The mounting hole has a small diameter, and as the refractory brick becomes thinner, the inner end of the mounting hole is located on the refractory brick, which easily forms a conical groove. It is not easy to measure the distance from the end face of the external thermocouple mounting flange to the bottom of the conical groove, so it is difficult to accurately adjust the installation length of the thermocouple. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Specific embodiment:
[0026] like Figure 1 and Figure 2As shown, the present application provides a gasifier thermocouple installation depth measuring device, including a measuring rod 1 and a positioning rod 2, one end of the measuring rod 1 is rotatably connected to one end of the positioning rod 2, specifically, the measuring rod 1 and the positioning rod 2 are both made of high-temperature resistant stainless steel, one end of the measuring rod 1 is provided with a connecting limit groove 11, one end of the positioning rod 2 is placed in the connecting limit groove 11, and a pin shaft 12 is used to pass through the connecting limit groove 11 and the positioning rod 2, so that the positioning rod 2 and the measuring rod 1 are rotatably connected, and the positioning rod 2 is connected with a high-temperature resistant pull rope 3 near the connection between the measuring rod 1 and the positioning rod 2, an elastic reset member 4 is provided between the measuring rod 1 and the positioning rod 2, one end of the elastic reset member 4 is connected to the positioning rod 2, and the other end of the elastic reset member 4 is connected to the measuring rod 1, specifically, a first connecting member 13 is provided on the measuring rod 1, and a second connecting member 21 is provided on the positioning rod 2, one end of the elastic reset member 4 is connected to the measuring rod 1 through the first connecting member 13, and the elastic reset member 4 The other end is connected to the positioning rod 2 through the second connecting piece 21. In the initial state, under the action of the elastic reset piece 4 and the connecting limit groove 11, the measuring rod 1 and the positioning rod 2 are connected to form a straight rod. When the utility model is used, the measuring rod 1 is rotated to insert the end connected with the positioning rod 2 into the thermocouple mounting hole, and then the positioning rod 2 is pulled by the high-temperature resistant pull rope 3. At this time, the positioning rod 2 rotates around the connection between the positioning rod 2 and the measuring rod 1 under the action of tension, so that one side of the positioning rod 2 is close to the inner wall of the conical groove on the refractory brick, and then the distance from the end face of the external thermocouple mounting flange to the bottom of the conical groove can be measured by the measuring rod 1. After the measurement is completed, the tension on the high-temperature pull rope is released. Under the action of the elastic reset piece 4, the positioning rod 2 returns to the initial state, and then the measuring rod 1 can be pulled out. The structure is simple and the design is reasonable. It effectively meets the actual on-site measurement needs of the installation length of the thermocouple, so that the installation length of the thermocouple can be accurately adjusted.
[0027] like Figure 2 As shown, a scale 5 is provided on the measuring rod 1, through which the depth of the measuring rod 1 inserted into the thermocouple mounting hole can be checked. When one side of the positioning rod 2 is in close contact with the inner wall of the conical groove on the refractory brick, the distance from the end face of the external thermocouple mounting flange to the bottom of the conical groove can be known from the scale 5.
[0028] like Figure 2 As shown, at least one limiting portion 6 is provided on the measuring rod 1 along the length direction, and the high temperature resistant pull rope 3 moves through the limiting portion 6. In the present embodiment, two limiting portions 6 are provided, and the high temperature resistant pull rope 3 moves through the two limiting portions 6. Through the setting of the limiting portions 6, the pulling direction of the positioning rod 2 is unique, which makes it easier for the positioning rod 2 to rotate.
[0029] like Figure 1 and Figure 2As shown, the high temperature resistant pull rope 3 is woven from ceramic fibers. The ceramic fibers have the characteristics of high temperature resistance and fire resistance, can be used in high temperature environments, meet actual use requirements, and can extend the service life of the high temperature resistant pull rope 3.
[0030] like Figure 1 and Figure 2 As shown, the length of the measuring rod 1 is 1000 mm to 1500 mm, and the width is 15 mm to 20 mm. In this embodiment, the length of the measuring rod 1 is 1500 mm, and the width is 20 mm, ensuring that it can be inserted into the thermocouple mounting hole.
[0031] like Figure 2 As shown, the length of the positioning rod 2 is 100 mm to 150 mm, and the width is 10 mm to 15 mm. In this embodiment, the length of the measuring rod 1 is 150 mm, and the width is 15 mm, ensuring that it can be inserted into the thermocouple installation hole.
[0032] like Figure 1 and Figure 2 As shown, the elastic reset member 4 is a high temperature resistant tension spring, so as to meet the use requirements in a high temperature environment.
[0033] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
