Description

Technical Field

[0001] The utility model relates to the technical field of thermal equipment protection, in particular to a heat insulation protection device for a temperature measuring tube of a high-temperature furnace. Background Art

[0002] High-temperature furnace temperature measurement refers to the process of accurately measuring the temperature inside the furnace under high-temperature environment, which is crucial for controlling the heat treatment process and ensuring material performance and quality. Thermocouple is a commonly used high-temperature temperature measurement element, which directly measures the temperature and converts the temperature signal into a thermoelectric potential signal, which is converted into the temperature of the measured medium through electrical instruments.

[0003] In the prior art, most high-temperature furnace temperature measurements are generally performed by inserting a temperature measuring probe composed of a thermocouple into the furnace to obtain temperature data. This probe is usually connected to a conduit with a high-temperature isolation function to facilitate the wiring of the probe. However, different types of thermocouples have different heat resistance limits. When it is necessary to continuously measure the temperature inside the high-temperature furnace, if the temperature inside the furnace rises to the maximum tolerance temperature of the temperature measuring tube, the temperature measuring tube will be scrapped and fail.

[0004] Therefore, the utility model provides a high-temperature furnace temperature measuring tube heat insulation protection device to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a heat insulation protection device for a temperature measuring tube of a high temperature furnace, such as Figure 1 and Figure 2 As shown, the thermal insulation protection device includes an outer shell 1, a fixed plate 2 fixedly installed at one end of the outer shell 1, a plurality of protective shells 6 slidably installed on the side of the fixed plate 2 away from the outer shell 1 for protecting the temperature measuring tube, an inner shell 9 fixedly connected to the inside of the outer shell 1, an adjustment mechanism arranged inside the outer shell 1 for adjusting the protective shell 6, and a limiting mechanism arranged on one side of the fixed plate 2 for limiting the protective shell 6.

[0026] The adjustment mechanism includes an adjustment plate 11 rotatably attached to one side of the fixed plate 2 , an adjustment column 7 fixedly mounted on the outer wall of the protective shell 6 and inserted into the adjustment plate 11 , and an adjustment tube 10 rotatably connected to the inner shell 9 .

[0027] The adjusting plate 11 is provided with an arc groove for the adjusting column 7 to slide.

[0028] The interior of the thermal insulation protection device is provided with a cavity for placing a temperature measuring tube, and the probe of the temperature measuring tube is installed in the cavity inside the protective shell 6. When it is necessary to measure the temperature inside the high-temperature furnace, the device is extended into the interior of the high-temperature furnace, and the adjusting plate 11 is driven to rotate by rotating the adjusting tube 10. The rotation of the adjusting plate 11 will cause the arc groove to squeeze the internal adjusting column 7, causing its position to move, thereby driving the protective shell 6 connected to the adjusting column 7 to unfold, exposing the probe of the temperature measuring tube for temperature measurement. Once the temperature in the furnace reaches a situation that the temperature measuring tube cannot withstand, the adjusting tube 10 is rotated in the opposite direction to close the two protective shells 6, thereby isolating the temperature measuring tube from contact with the high temperature in the furnace, thereby achieving the purpose of protecting the temperature measuring tube.

[0029] Furthermore, in order to improve the stability of the protective shell 6 during use, as Figure 1 and Figure 5 As shown, the limiting mechanism includes a plurality of sliders 5 fixedly mounted on the outer surface of the protective shell 6, a plurality of connecting blocks 3 fixedly mounted on the side of the fixing plate 2 away from the outer shell 1, and a plurality of limiting strips 4 fixedly mounted on the connecting blocks 3 for limiting the sliders 5.

[0030] The slider 5 is slidably connected to the limit bar 4 , and the limit bar 4 limits the slider 5 . The slider 5 is connected to the protective shell 6 , so that the protective shell 6 can only move in the horizontal direction, thereby ensuring the stability of the protective shell 6 .

[0031] Furthermore, in order to improve the stability of the regulating tube 10 during use, as Figure 4 As shown, the adjustment tube 10 passes through the fixing plate 2 , and one end of the adjustment tube 10 close to the protection shell 6 is fixedly connected to the adjustment plate 11 .

[0032] By disposing the adjusting tube 10 and the adjusting plate 11 , the adjusting tube 10 is not easily deviated when rotating, thereby improving the stability of the adjusting tube 10 when in use.

[0033] It should be noted that in order to prevent the adjustment plate 11 from being easily deflected during rotation, Figure 1 and Figure 4 As shown, one side of the adjustment plate 11 is rotationally fitted with one side of the limiting strip 4 .

[0034] A plurality of limiting bars 4 are symmetrically arranged on both sides of the adjusting plate 11 for clamping the adjusting plate 11 , and at the same time, both sides of the adjusting plate 11 are clamped by the limiting bars 4 and the fixing plate 2 .

[0035] Furthermore, in order to protect the safety inside the device, Figure 2 As shown, the outer wall of the inner shell 9 is fixedly connected with a heat insulation board 8 .

[0036] A certain gap is left between the inner shell 9 and the outer shell 1, and a heat insulation board 8 is installed in the gap to reduce the risk of high temperature intrusion into the interior of the device.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
