Description

Technical Field

[0001] The invention relates to the technical field of temperature measurement, and in particular to a tool for detecting the temperature of a heating furnace. Background Art

[0002] Industrial furnaces are thermal equipment that uses heat from fuel combustion or electrification to heat materials or workpieces in industrial production. Industrial furnaces (also called heat treatment furnaces, heating furnaces, continuous furnaces or experimental furnaces for finished product testing) need to be tested for temperature uniformity when they are newly built, in use, or after repair. There are two traditional methods for testing furnace temperature uniformity:

[0003] The first detection method is: after the operation in the furnace is completed and the temperature in the furnace drops to room temperature, personnel need to enter the furnace, set the thermocouple for detecting the temperature at a location point in a specific area of ​​the furnace, and lead the thermocouple line out of the furnace and connect it to an external recording device, then turn on the industrial furnace for heating and insulation, and use the thermocouple to detect the temperature changes in the furnace during the whole process, and transmit the temperature values ​​to the external recording device for recording and analysis. After the detection is completed, it is necessary to wait until the temperature in the furnace drops to room temperature, and then personnel enter the furnace again to remove the thermocouples one by one.

[0004] The second detection method is: after the internal work is completed and the temperature drops to normal temperature, the personnel enter the furnace, set the black box furnace temperature tester and the thermocouple at the location point in the specific area of ​​the furnace, and after the installation is completed, reopen the industrial furnace for heating and insulation, and use the thermocouple to detect the temperature change in the furnace during the whole process, and transmit the detected temperature data to the black box furnace temperature tester, which transmits the received temperature data to the recording device outside the furnace by wireless transmission for recording and analysis; then after the detection is completed, the temperature in the furnace needs to be lowered to normal temperature, and the personnel enter the furnace again to remove the relevant detection instruments or devices one by one.

[0005] In the above two detection methods, the operators need to enter the furnace twice during the whole detection process, which is labor-intensive. In addition, due to the limited space of the furnace, it is difficult to operate, time-consuming and labor-intensive. For natural gas furnaces, there are also certain risks in working in the furnace. More importantly, both detection methods require waiting for the temperature in the furnace to drop to room temperature before working, resulting in too long waiting time, low detection efficiency, and also occupying the normal operation time of the industrial furnace to a large extent, greatly affecting production efficiency. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a tool for detecting the temperature of a heating furnace, so as to solve the problems of the furnace temperature detection method in the prior art being labor-intensive, inefficient and affecting normal production.

[0008] Furthermore, each of the brackets can be detachably fixed on the cage body.

This not only improves detection efficiency and operational safety, but also reduces energy consumption and saves a long furnace shutdown time. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figures 1 to 5 It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner, and the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0036] The present invention provides a tool for detecting the temperature of a heating furnace (hereinafter referred to as "detection tool"), such as Figures 1 to 5As shown, the detection tooling includes a cage body 10, a plurality of brackets and a data acquisition module 30, wherein the plurality of brackets are connected to the cage body 10, and the plurality of brackets are spaced apart along the circumferential direction of the cage body 10, and a thermocouple 40 is provided on each bracket; the data acquisition module 30 is arranged in the cage body 10, and the data acquisition module 30 includes a heat insulation box, a data receiving unit and a wireless transmission unit, the data receiving unit and the wireless transmission unit are both arranged in the heat insulation box, and the data receiving unit is communicatively connected to the wireless transmission unit, and all the thermocouples 40 arranged on the brackets are communicatively connected to the data receiving unit.

[0037] The beneficial effect of the tooling for detecting the temperature of a heating furnace of the present invention is as follows: when it is necessary to detect the uniform temperature of the heating furnace, firstly, the data acquisition module 30 is placed in the cage 10 outside the heating furnace, and thermocouples 40 (such as Figure 5 As shown), all the thermocouples are connected to the data receiving unit of the data acquisition module 30, and then the detection tooling equipped with the data acquisition module 30 and arranged with several thermocouples is placed into the furnace of the heating furnace through a sling, and then the furnace door of the heating furnace is closed, and corresponding detection is performed according to the furnace temperature measurement process. During the furnace temperature measurement, the temperature data detected by the thermocouple will be transmitted to the data receiving unit of the data acquisition module 30. After the data receiving unit receives the data detected by the thermocouple, the wireless transmission unit of the data acquisition module 30 will transmit the detected temperature data to an external computer device for analysis by wireless transmission. After the furnace temperature measurement is completed, the detection tooling can be taken out of the heating furnace as a whole through a special sling. Therefore, by using the detection tooling of the present invention, when performing uniform temperature detection on the heating furnace, there is no need to wait for the temperature in the furnace to drop to room temperature, and there is no need for detection personnel to enter the furnace to set up and disassemble thermocouples and detection instruments. Based on the detection tooling of the present invention, the arrangement of thermocouples and data acquisition modules in the heating furnace can be completed during normal production intervals, that is, when the furnace is in a high temperature state (without stopping the furnace), thereby meeting the requirements of furnace temperature uniformity measurement, saving the time required for waiting for the temperature in the furnace to cool to room temperature in the traditional uniform measurement method, and saving the time and energy for production heating after the uniform measurement. This not only improves detection efficiency and operation safety, but also reduces energy consumption and saves a long furnace shutdown time.

[0038] Further, in this embodiment, the heat insulation box includes a shell and a water tank disposed in the shell, and the shell and the water tank are filled with heat insulation material. Specifically, the water tank is filled with water, and the water tank encloses a heat insulation space, and the data receiving unit and the wireless transmission unit are disposed in the heat insulation space. Preferably, in this embodiment, the heat insulation material is fiber cotton.

[0039] Furthermore, if Figure 2As shown, in this embodiment, the cage 10 is square, and eight brackets are provided. Each bracket is provided with two thermocouples 40 at one end away from the cage 10, and the two thermocouples are arranged at intervals up and down. Specifically, the eight brackets include four first brackets 21, two second brackets 22 and two third brackets 23, wherein, as shown in FIG. Figure 2 As shown, four first brackets 21 are respectively arranged at the four corners of the cage 10, two second brackets 22 are respectively arranged at the two sides of the cage 10, and two third brackets 23 are respectively arranged at the other two sides of the cage 10; specifically, in this embodiment, the length of the first bracket 21 is greater than the length of the second bracket 22, and the length of the second bracket 22 is greater than the length of the third bracket 23. Through this structural design, that is, brackets of different lengths are arranged on the four vertical edges and four sides of the cage along the circumferential direction of the cage 10, so that the ends of the multiple brackets (the end away from the cage 10) can be located at different positions in the heating furnace, so that the thermocouples arranged at the ends of the brackets can detect the temperature of different positions in the heating furnace, thereby improving the accuracy of the detection of the uniform temperature of the heating furnace.

[0040] Specifically, Figure 2 As shown, in this embodiment, four first brackets 21 are symmetrically arranged on the cage body 10, two second brackets 22 are symmetrically arranged on the cage body 10, and two third brackets 23 are symmetrically arranged on the cage body 10, thereby improving the stability of the detection tooling placed in the furnace of the heating furnace.

[0041] Furthermore, in the present embodiment, each bracket can be detachably fixed on the cage body 10. Thus, in actual use, brackets of different lengths can be replaced according to the size of the furnace of the heating furnace, that is, the first bracket 21 of different lengths, the second bracket 22 of different lengths, and the third bracket 23 of different lengths can be replaced, so that the detection tool can be applied to heating furnaces of different sizes for temperature uniformity detection, thereby improving the applicability of the detection tool. Specifically, in actual use, in order to adapt to different detection ranges, the installation positions of the first bracket 21, the second bracket 22, and the third bracket 23 on the cage body 10 can also be adjusted accordingly according to the shape and size of the furnace of the heating furnace.

[0042] Furthermore, if Figure 1 As shown, in this embodiment, a plurality of plug holes 101 are provided on the cage body 10, and the brackets are plugged into and matched with the plug holes 101 on the cage body 10, so that the brackets, namely the first bracket, the second bracket and the third bracket, are installed on the cage body 10 simply and quickly.

[0043] Furthermore, in this embodiment, the material of the cage body 10 is preferably ZG40Cr25Ni20Si2, and the material of the bracket is preferably 310S stainless steel, so as to ensure that the cage body and the bracket can maintain a certain strength at 1200°C for 15 hours and meet the high-temperature test environment conditions in the furnace and the lifting requirements for entering and exiting the furnace at 1200°C.

[0044] Furthermore, in order to facilitate the lifting of the detection tool, Figure 1 As shown, in this embodiment, a lifting ring 102 is provided on the top of the cage body 10. When the detection tool is lifted into the furnace of the heating furnace, or when the detection tool is lifted out of the furnace of the heating furnace, as shown in FIG. Figure 3 As shown, a lifting shaft 100 is inserted into the lifting ring 101, and then the lifting shaft is clamped by an axial lifting device to lift the detection tool and put it into the heating furnace. Figure 3 As shown, the lifting shaft 100 includes a first end and a second end. The first end of the lifting shaft 100 is provided with two retaining rings, and the two retaining rings are arranged at intervals. The second end of the lifting shaft 100 is provided with a clamping portion 100a. When lifting the detection tooling, the first end of the lifting shaft 100 is inserted into the lifting ring 101, and the lifting ring 102 is located between the two retaining rings, so that the two retaining rings can limit the detection tooling during lifting to prevent it from sliding along the axial direction of the lifting shaft, and then the clamping portion 100a of the second end of the lifting shaft is clamped by the axial lifting device to lift the detection tooling by the axial lifting device.

[0045] In summary, the tooling for detecting the temperature of a heating furnace of the present invention can complete the temperature uniformity detection of the heating furnace during normal production intervals, that is, without stopping the furnace, saving the time required by the traditional uniform measurement method to wait for the temperature in the furnace to cool to room temperature, and also saving the time and energy for production heating after the uniform measurement, which not only improves the detection efficiency and operation safety, but also reduces energy consumption and saves a long shutdown time. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
