[0027] As shown in Figures 1 to 6 An assembly set suitable for a rotary converter furnace temperature detection infrared probe, comprising a sleeve main body 10, end pipes 20 and end caps 30 fixed respectively at the left and right ends of the sleeve main body 10, and a support frame 40. After being assembled together, the pipe cavity of the end pipe 20, the cap cavity of the end cap 30 and the shaft hole 11 of the sleeve main body 10 are all through and connected in the axial direction, forming a flow channel for cold air / cold gas medium flow. The sleeve main body 10 is made of heat insulation material, or a heat insulation sleeve / heat insulation sleeve pipe is fixed on the outside of the sleeve main body 10 and / or the inside of the shaft cavity 11. The heat insulation sleeve and the heat insulation sleeve pipe, also known as heat insulation sleeve and heat insulation sleeve pipe, can reduce the initial temperature / high temperature range in the shaft hole 11 and the cap cavity of the end cap 30 to the greatest extent and reduce the cooling pressure.

[0028] A transparent window is provided on the closed end of the end cap 30, and the detection end of the infrared probe 50 can pass through the transparent window to detect the temperature of the top inner surface of the furnace lining. The transparent window can be made of high-temperature-resistant glass or other high-temperature-resistant transparent materials.

[0029] A counterbore 12 is formed on the end face of the sleeve main body 10 where the end cap 30 is arranged, and the support frame 40 can be fixed in the counterbore 12. Figures 1 to 4As shown, the support frame 40 includes a pair of clamping plates, which are arranged opposite each other to clamp the infrared probe 50 between them. The countersunk hole 12 has corresponding slots 121 on its upper and lower ends, respectively. During assembly, the two clamping plates are pushed into the cavity of the countersunk hole 12 along the axial direction. The protruding rails 42 on the upper and lower parts of the clamping plates then mate with the slots 121, thus fixing the support frame 40 within the countersunk hole 12. The axial extension length of the clamping plate is not greater than the axial extension depth of the countersunk hole 12. The protruding rails 42 and the slots 121 have a profile contact matching relationship and are an interference fit.

[0030] A plurality of interconnecting holes 13 are formed on the wall of the sleeve body 10 in a circumferentially spaced manner. A sealing ring 15 is disposed on the other end face of the sleeve body 10 (i.e., the end face that abuts with the end tube 20). After the end tube 20 and the sleeve body 10 are connected together, a seal can be formed between their opposing surfaces by means of the sealing ring 15.

[0031] An axial flange 21 is formed on the outer end face of the end pipe 20, and an annular groove 22 is formed on the inner end face. A radial flange 23 communicating with the annular groove 22 is formed on the side wall of the end pipe 20. The axial flange 21 is connected to a pipe fitting and can introduce cold air / cold medium gas for cooling into the shaft cavity 11 and deliver it to the cap cavity of the end cap 30. The radial flange 23 is connected to a fan (such as a duct fan) through a pipe fitting and can draw the heat-exchanged gas medium to the outside.

[0032] An annular flange is formed on the inner side of the port of the end cap 30, and a plurality of interconnecting holes 321 are formed on the annular flange in a circumferentially spaced manner. The annular flange and the interconnecting holes 321 thereon can relatively slow down the speed at which the cold medium airflow flows out of the cap cavity of the end cap 30, so that the incoming cold medium airflow can have a longer contact time with the countersunk hole 12 and the hot air inside the end cap 30, so as to promote sufficient convective heat exchange between the cold and hot gases, thereby enabling the surrounding space of the infrared probe 50 to achieve a good cooling effect.

[0033] Each of the connecting holes 13 has one end (left end) that can simultaneously connect to the annular recess 22, and the other end (right end) that can correspondingly connect to the connecting hole 321, thereby connecting the shaft cavity 11, the cap cavity of the end cap 30, and the radial edge tube 23 to establish a flow channel for heat exchange airflow. See [reference needed] Figure 1 The arrow shown. Specifically, as... Figure 1 , Figure 2As shown, on the sleeve body 10, an end face recess 14 is formed on the end face of the end cap 30 and at the outer peripheral position of the counterbore 12. The other end (right end) of each communication hole one 13 can simultaneously communicate with the end face recess 14 and can be communicated with each communication hole two 321 through the end face recess 14. The axial extension direction of the communication hole one 13 is preferably radially outward relative to the axial extension direction of the communication hole two 321 (i.e., on the side away from the axial center line of the axial cavity 11), see Figure 1 As shown in the state.

[0034] A pivot body 51 corresponding to the support frame 40 is provided on the housing of the infrared probe 50. Through the structure of matching connection between the pivot body 51 and the support frame 40, the infrared probe 50 can make rotational movement in the vertical plane relative to the support frame 40, and the detection end of the infrared probe 50 is kept in the state of extending into the cap cavity of the end cap 30. At the same time, a locking assembly that can regulate the matching state between the infrared probe 50 and the support frame 40 is arranged on the support frame 40. The locking assembly can switch the infrared probe 50 between the state of making rotational movement relative to the support frame 40 and the state of keeping fixed relative to the support frame 40.

[0035] The area of the transparent window provided on the end cap 30 can meet the detection needs of the infrared probe 50 when it rotates to different angles (relative to the axial direction or relative to the horizontal direction), that is, the infrared probe 50 can make its detection end measure the temperature of the inner surface at the top of the furnace lining through the window in a wide rotational range.

[0036] The end cap 30 includes a cap body 31 and a connecting ring 32 connected together through a threaded structure, and the communication hole two 321 is distributed on the connecting ring 32. One end of the connecting ring 32 is connected to the sleeve body 10 through a threaded structure, and the other end face is distributed with a fin group 322 extending in the axial direction, and the fin group 322 is located on the inner side of the communication hole two 321, that is, the fin group 322 is distributed between the inner circumference of the connecting ring 32 and the circumference where the communication hole two 321 is distributed.

[0037] In order to improve the convective heat transfer effect between the cooling fluid (such as cold air) and hot air in the end cap 30, ensure the sufficiency / overall / relative uniformity of cooling (i.e., the overall temperature in the continuous space such as the counterbore 12 and the cap cavity tends to be consistent), and promote the entire infrared probe 50 to be in a good low-temperature environment, the following can be done Figure 1 , Figures 5 to 6The design shown: that is, the fin plate group 322 includes three multiple turns of fin plates distributed coaxially, and the axial length of the fin plates located on the inner side of each turn is greater than that of the fin plates located on the outer side of each turn. The multiple fin plates in each turn are distributed in the circumferential direction, and the fin plates in adjacent turns are in a state of relative staggered distribution, as shown in Figure 6 .

[0038] As Figure 4 shown, the protrusions 41 corresponding to the pivot body 51 are formed on the opposite surfaces of the clamping plate. A sliding groove 411 is formed on the free end surface of the protrusion 41, and a prismatic through hole 412 is formed at the bottom of the sliding groove 411. The groove depth extension direction of the sliding groove 411 and the axial extension direction of the prismatic through hole 412 are consistent with the axial direction of the pivot body 51. The pivot body 51 and the shell of the infrared probe 50 can be integrally formed; or they can be detachably connected through a threaded structure, as shown in the Figure 4 embodiment: a threaded rod segment 513 is provided at one end of the pivot body 51, which corresponds to the threaded counterbore structure on the shell. The (functional) body of the infrared probe 50 is fixed in the shell, and only the shell is shown in the figure.

[0039] The locking assembly includes a sliding sleeve assembly 43 and a screw ring body 44. The sliding sleeve assembly 43 matches the sliding groove 411 and can reciprocally move relative to the sliding groove 411 (in the axial direction of the pivot body 51). The sliding sleeve assembly 43 is formed with a shaft portion one 4322 and a shaft portion two 4323 at one end thereof toward the sliding groove 411, and the shaft portion one 4322 corresponds to the prismatic through hole 412. The free end of the shaft portion two 4323 extends out of the prismatic through hole 412 and is configured with the screw ring body 44, that is, the outer periphery of the shaft portion two 4323 is an external thread surface. The shaft portion one 4322 is a prismatic body, and the outer diameter of the shaft portion one 4322 is consistent with the inner diameter of the prismatic through hole 412, so that a profile contact matching relationship is established therebetween, so that the shaft portion one 4322 can move along the axial direction (of the pivot body 51) relative to the prismatic through hole 412, and the length of the shaft portion two 4323 extending out of the prismatic through hole 412 can be changed. The outer diameter of the shaft portion two 4323 is smaller than the inner diameter of the prismatic through hole 412. After assembly, the end side of the shaft portion one 4322 can always remain matched with the prismatic through hole 412.

[0040] The outer diameter of the screw ring body 44 is greater than the inner diameter of the prismatic through hole 412. In order to reduce the overall thickness of the clamping plate and the locking assembly after assembly (that is, the thickness of the clamping plate and the locking assembly in the direction perpendicular to the axial direction of the pivot body 51), the outer diameter of the screw ring body 44 is greater than the inner diameter of the prismatic through hole 412. Figure 4The axial flange body is formed on the toroid 44, the internal thread surface 441 of the toroid 44 is formed on the inner circumferential surface of the axial flange body, and the axial flange body can extend into the prismatic hole 412.

[0041] The axial position of the toroid 44 on the shaft portion two 4323 is adjusted by screwing the toroid 44, which can cause the sliding sleeve assembly 43 to move relative to the sliding groove 411 to control the matching state between the sliding sleeve assembly 43 and the pivot body 51, so that the infrared probe 50 can be switched between the state of rotating relative to the support frame 40 and the state of being fixed relative to the support frame 40.

[0042] The axial flange body is formed on the toroid 44, the internal thread surface 441 of the toroid 44 is formed on the inner circumferential surface of the axial flange body, and the axial flange body can extend into the prismatic hole 412.

[0043] The sliding sleeve assembly 43 includes a sleeve body one 431 and a sleeve body two 432 connected as a whole by a threaded structure, and a spring 433. The shaft portion one 4322 and the shaft portion two 4323 are formed on the free end of the sleeve body two 432. The spring 433 is sleeved on the shaft portion one 4322, and the two ends of the spring 433 are in contact and matching with the end face of the sleeve body two 432 and the inner bottom surface of the sliding groove 411, respectively, which can produce extension and contraction deformation during the movement of the sliding sleeve assembly 43 relative to the sliding groove 411.

[0044] The radial flange one 4311 corresponding to the light column surface segment 512 is formed on the inner wall of the sleeve body one 431, which is preferably annular, and the inner circumferential surface of the radial flange one 4311 is formed as a light surface in contact and matching with the light column surface segment 512. The radial flange two 4321 in the form of a ring is formed on the inner wall of the sleeve body two 432, and the inner circumferential surface of the radial flange two 4321 is formed as a fine tooth surface / fine tooth circumferential surface corresponding to the fine tooth surface segment 511. By corresponding setting the fine tooth body capable of engaging and matching on the fine tooth surface segment 511 and the inner circumferential surface of the radial flange two 4321, the fine tooth surface segment 511 and the radial flange two 4321 can be smoothly and reliably switched from the disengaged state to the engaged state, realizing the locking of the position of the pivot body 51 (or the infrared probe 50), so that it cannot rotate around the axis.

[0045] The outer diameter of the fine tooth surface section 511 is greater than the outer diameter of the light column surface section 512, and the difference between the outer diameters is preferably controlled to be greater than 2mm. By screwing the toroid 44 so that the internal thread surface 441 corresponds to different positions on the shaft portion two 4323, the sliding sleeve assembly 43 can be moved in the left-right direction as shown, and the radial flange two 4321 is selectively disengaged from and engaged with the fine tooth surface section 511. Figure 4 The radial flange two 4321 is selectively disengaged from and engaged with the fine tooth surface section 511 by moving the sliding sleeve assembly 43 in the left-right direction as shown. To facilitate smooth movement of the radial flange two 4321 from the disengaged state to the engaged state with the fine tooth surface section 511, a tapered surface section is formed between the fine tooth surface section 511 and the light column surface section 512, and the small-diameter end of the tapered surface section is directed toward the light column surface section 512.

[0046] The assembly is used to match the infrared temperature measurement probe arranged on the chimney wall, can not only realize the adjustment and control of the temperature measurement direction / position of the infrared probe, but also can realize the temperature control of the temperature near the periphery of the body of the infrared probe, finally realizes the purpose that the infrared probe operates in a stable low temperature environment, helps to inhibit the damage of the infrared (temperature measurement) probe due to long-term operation in a high temperature environment, and helps to reduce the use and maintenance cost of the temperature measurement device.
