Description

Technical Field

[0001] The present invention belongs to the technical field of thermocouples, and more specifically, relates to thermocouples used in the field of pipelines and related installation and use methods thereof. Background Art

[0002] Thermocouples are commonly used temperature testing instruments, often used in various occasions or reaction devices that require temperature control, such as chemical reactors, sintering furnaces, etc. In most cases, thermocouples are used in an inserted manner, that is, the thermocouple as a whole or the thermocouple temperature measuring end or the temperature measuring core is installed in chemical reactors, sintering furnaces and other equipment to monitor the temperature of the temperature-measured part. However, in some special fields or some special locations, it is required to monitor the temperature of the surface (or outer surface). In this case, the temperature sensor (ie, thermocouple) is required to be set on the surface to be measured to achieve temperature measurement. However, for the measurement of outer surface temperature, how to install it firmly and accurately test the temperature is a major problem facing the industry.

[0003] The prior art "clamp-type surface temperature sensor" (application number 2015200885522, application date February 9, 2015, authorization announcement date June 3, 2015) proposes a clamp-type structure for measuring the temperature of the outer surface of the pipeline, but this structure is a thermocouple with a relatively fixed temperature measurement position, and can only achieve single-point measurement on the circumference, which cannot meet the increasingly diverse requirements of customers in actual use. Our company's R&D team has been committed to the temperature measurement thermocouples on the inner and outer surfaces of customers' pipelines, and launched the "slide rail clamp-type thermocouple" (application number 202220088540X, application date January 13, 2022, authorization announcement date October 28, 2022), forming a sliding track between different clamps, and the sliding base can slide freely along the sliding track, so that the temperature measurement component can be adjusted in different measurement processes by adjusting the position of the temperature measurement component on the clamp, so that it can achieve the purpose of measuring the temperature of different positions on the surface of the pipeline and equipment in different measurement processes.

[0004] Whether it is a "clamp-type surface temperature sensor" or a "slide rail clamp-type thermocouple", when measuring the temperature of the outer surface of the pipeline, the thermocouple head (including the junction box of the thermocouple) structure needs to occupy a large space, which requires a large space for the installation and use of this type of thermocouple, and is often suitable for a certain pipeline, or pipelines with a large distance between each other. For a tube-in-tube structure composed of multiple pipelines (the distance between pipelines is small), or an internal pipeline in a casing structure, there is a lack of installation space for use, but in engineering practice, the outer surface of a specific pipeline needs to be measured and / or monitored. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a pipe outer surface temperature measuring mounting bracket and a thermocouple using the bracket.

[0006] The technical purpose of the present invention is achieved through the following technical solutions.

[0007] The temperature measuring and mounting bracket of the pipe outer surface includes a heat collecting block and a clamp, wherein:

[0008] The heat collecting block and the clamp are connected to form a space for arranging the pipe to be temperature measured between the two;

[0009] A temperature measuring hole is provided on the heat collecting block for setting a temperature measuring core of a thermocouple.

[0010] The heat collecting block is made of a material that is easy to conduct heat; the heat collecting block is in an arc shape as a whole, and the clamp is in an arc shape or a U shape as a whole, and the two cooperate to fix the pipe to be measured.

[0011] The temperature measuring hole is a temperature measuring through hole so that the temperature measuring core of the thermocouple passes through the temperature measuring hole. The temperature measuring hole on the heat collecting block is arranged near the position of the pipe to be measured so that the temperature measuring core of the thermocouple is close to the pipe to be measured.

[0012] A top screw is arranged on the heat collecting block, the top screw passes through the heat collecting block and is connected with the temperature measuring hole so as to fix the temperature measuring core of the thermocouple arranged in the temperature measuring hole.

[0013] The heat collecting block and the clamp are connected via a fixed connection piece, which is a bolt and a nut that fit together.

[0014] The thermocouple using the above-mentioned pipe outer surface temperature measuring mounting bracket includes a mounting flange, a connecting protective sleeve, and a junction box. The above-mentioned pipe outer surface temperature measuring mounting bracket is arranged on the temperature measuring core of the thermocouple. When in use, the pipe to be measured is arranged between the heat collecting block and the clamp and fixed. The temperature measuring core of the thermocouple is fixed in the temperature measuring hole by a top screw, so that the temperature measuring core of the thermocouple is fixed at the temperature measuring position of the pipe to be measured.

[0015] The temperature measuring core of the thermocouple is an armored thermocouple temperature measuring core or a thermocouple wire.

[0016] The temperature measuring core of the thermocouple is a single-branch single-point armored thermocouple temperature measuring core or a single-branch multi-point armored thermocouple temperature measuring core.

[0017] Compared with the prior art, the present invention provides a temperature measurement installation bracket for the outer surface of a pipeline and a thermocouple using the bracket, which no longer uses the previous clamp structure and couple head design and can be used in a tube array or sleeve structure to achieve temperature measurement and / or monitoring of the outer surface of the pipeline, and is easy to use.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below in conjunction with specific embodiments.

[0024] like Figure 1 —4 shows a detailed description of the pipe outer surface temperature measuring mounting bracket and the thermocouple using the bracket of the present invention.

[0025] In the prior art "clamp-type surface temperature sensor" and "slide rail clamp-type thermocouple", the thermocouple head (including the junction box of the thermocouple) can be understood as Figure 4 The structure on the left side of the mounting flange 8 - the connecting protective sleeve 9 and the junction box 10 - needs to occupy a large space, which requires a large space for the installation and use of this type of thermocouple. Take the tube-in-tube structure that appears in large chemical reaction equipment as an example. In this structure, the distance between different pipes is very small, and it is impossible to provide a large space for the installation and use of thermocouples.

[0026] The temperature measuring and mounting bracket of the pipe outer surface includes a heat collecting block and a clamp, wherein:

[0027] The heat collecting block and the clamp are connected to form a space for arranging the pipe to be temperature measured between the two.

[0028] A temperature measuring hole is provided on the heat collecting block for setting a temperature measuring core of a thermocouple.

[0029] The temperature measuring hole is a temperature measuring through hole so that the temperature measuring core of the thermocouple passes through the temperature measuring hole.

[0030] The heat collecting block is made of a material that is easy to conduct heat; the heat collecting block is in an arc shape as a whole, and the clamp is in an arc shape or a U-shape as a whole, and the two cooperate to fix the pipe to be measured temperature. When pulled, the heat collecting block and the clamp respectively clamp the upper and lower outer surfaces of the pipe to be measured temperature.

[0031] The temperature measuring hole on the heat collecting block is arranged close to the pipe to be temperature measured, so that the temperature measuring core of the thermocouple is close to the pipe to be temperature measured.

[0032] A top screw is arranged on the heat collecting block, the top screw passes through the heat collecting block and is connected with the temperature measuring hole so as to fix the temperature measuring core of the thermocouple arranged in the temperature measuring hole.

[0033] The heat collecting block and the clamp are connected via a fixed connection piece, which is a bolt and a nut that fit together.

[0034] A thermocouple using a pipe outer surface temperature measuring mounting bracket includes a mounting flange, a connecting protective sleeve, and a junction box. The above-mentioned pipe outer surface temperature measuring mounting bracket is arranged on the temperature measuring core of the thermocouple. When in use, the pipe to be measured is arranged between the heat collecting block and the clamp and fixed. The temperature measuring core of the thermocouple is fixed in the temperature measuring hole by a top screw, so that the temperature measuring core of the thermocouple is fixed at the temperature measuring position of the pipe to be measured.

[0035] The temperature measuring core of the thermocouple is an armored thermocouple temperature measuring core or a thermocouple wire.

[0036] The temperature measuring core of the thermocouple is a single-branch single-point armored thermocouple temperature measuring core or a single-branch multi-point armored thermocouple temperature measuring core.

[0037] In the technical solution of the present invention, the clamp and coupler head design used in the prior art are abandoned, so it is no longer necessary to occupy a large space. According to the specific space conditions in engineering practice, the outer surface temperature measurement mounting brackets of the pipes can be respectively set on different pipes of the tube structure (such as the size of the heat collecting block and the clamp can be adjusted according to the specific space conditions), and the heat collecting block and the clamp can be used to cooperate with each other to fix on the temperature measurement position of the pipe to be measured, and then the temperature measurement core of the thermocouple is set (such as fixed by a top screw) in the temperature measurement hole of the heat collecting block to achieve temperature measurement and / or monitoring of the specific temperature measurement position of the pipe to be measured. The thermocouple as a whole adopts multiple single-branch single-point armored thermocouple temperature measurement cores or single-branch multi-point armored thermocouple temperature measurement cores, and cooperates with multiple pipe outer surface temperature measurement mounting brackets to measure the temperature and / or monitor multiple pipes to be measured or multiple temperature measurement positions of the pipe to be measured. The remaining mounting flanges, connecting protective sleeves, and junction boxes of the thermocouples can be set and coordinated with reference to the relevant prior art.

[0038] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
