[0034] In a typical implementation of the present invention, Figure 1 As shown, a telescopic adjustment device for temperature measurement of a pressure vessel is proposed, which includes a flange cover 1, a sleeve 2, a positioning ring 3, a clamping flange 4, etc. The bottom of the flange cover 1 is fixedly connected to the sleeve 2, and the top of the flange cover 1 is fixedly connected to the clamping flange 4; a temperature measuring guide rod 5 is passed through the sleeve 2, and a positioning ring 3 is arranged outside the temperature measuring guide rod 5, and the positioning ring 3 contacts the inner wall of the sleeve 2.

[0035] Among them, the bottom of the flange cover 1 is installed on the equipment flange 10; specifically, through holes are evenly distributed on the outer circumference of the flange cover 1, and the positions and numbers of the through holes correspond to the through holes on the equipment flange 10. Bolts are used to pass through the through holes of the two to connect the flange cover 1 and the equipment flange 10.

[0036] It should be noted that the equipment flange 10 refers to the original pipe flange of the equipment itself. The equipment here refers to a pressure vessel. In this embodiment, the equipment specifically refers to a reactor. The flange cover 1 is directly installed on the original flange of the equipment without the need for additional openings to avoid unnecessary leakage points.

[0037] A central through hole is opened in the center of the flange cover 1, and the diameter of the central through hole is larger than the outer diameter of the temperature measuring guide rod 5, so that the temperature measuring guide rod 5 can pass through; a number of screw holes are also evenly distributed on the top of the flange cover 1, and the number and position of the screw holes correspond to the mounting holes of the clamping flange 4. In this embodiment, 4 screw holes are set in the flange cover 1.

[0038] The sleeve 2 is fixed to one end of the flange cover 1 close to the equipment flange 10 . The sleeve 2 and the flange cover 1 can be fixed by welding. The sleeve 2 passes through the middle through hole of the equipment flange 10 and extends downward.

[0039] The side wall of the sleeve 2 is evenly provided with medium passing holes, so that the medium in the reactor can freely pass through the sleeve 2. In an optional embodiment, the medium passing holes can be in the form of circular holes.

[0040] In other optional embodiments, the sleeve 2 may also be a tubular structure formed by strip weaving. In this embodiment, the gap formed by weaving constitutes a medium passing hole.

[0041] In more optional embodiments, such as Figure 4 As shown, vertical elongated holes 11 are evenly distributed along the circumferential direction on the side wall of the sleeve 2. In this embodiment, the vertical elongated holes 11 constitute medium passing holes.

[0042] The length of the sleeve 2 is determined according to the height of the agitator blades in the reactor and cannot interfere with the blades; the sleeve 2 is shorter than the temperature measuring guide rod 5, and the temperature measuring guide rod 5 is telescopically adjustable. Considering the corrosion of the medium, the material of the sleeve 2 must be consistent with the reactor equipment body.

[0043] Furthermore, the bottom of the temperature measuring guide rod 5 extends out of the casing 2, and the top of the temperature measuring guide rod 5 extends out of the flange cover 1 and the clamping flange 4. A positioning ring 3 is arranged on the outer periphery of the portion of the temperature measuring guide rod 5 located inside the casing 2, and the positioning ring 3 is located between the temperature measuring guide rod 5 and the inner wall of the casing 2, and the casing 2 and the positioning ring 3 together achieve the function of fixing the temperature measuring guide rod 5.

[0044] like Figure 3 As shown, the positioning ring 3 is fixed on the temperature measuring guide rod 5, and its material is the same as that of the reactor equipment body. There are several fulcrums on the outside of the positioning ring 3 that contact the inner wall of the sleeve 2. The maximum diameter at the fulcrum of the positioning ring 3 is the same as the inner diameter of the sleeve 2, which plays a role in fixing the temperature measuring guide rod 5 and preventing it from shaking.

[0045] Specifically, a groove is provided on the outer side of the temperature measuring guide rod 5 , the positioning ring 3 is clamped in the groove, and the positioning ring 3 is fixedly connected to the temperature measuring guide rod 5 .

[0046] In this embodiment, six fulcrums are arranged on the periphery of the positioning ring 3 to contact the inner wall of the sleeve 2, and a petal-shaped structure is formed on the periphery of the positioning ring 3. That is, the periphery of the positioning ring 3 is not circular, but is arranged in a curved form, and the contact surface between the positioning ring 3 and the sleeve 2 can be reduced by contacting the sleeve 2 at a plurality of fulcrums, so that the positioning ring 3 can slide up and down in the sleeve 2.

[0047] The position of the positioning ring 3 on the temperature measuring guide rod 5 is set according to the sleeve 2, and the length of the sleeve 2 is the telescopic adjustment range of the temperature measuring guide rod 5; when the positioning ring 3 is adjusted to reach the top position of the sleeve 2, the bottom of the temperature measuring guide rod 5 is retracted into the sleeve 2, or slightly extends out of the sleeve 2. When the positioning ring 3 reaches the bottom of the sleeve 2, the temperature measuring guide rod 5 is extended the longest, that is, the deepest position that can measure temperature.

[0048] In order to facilitate the installation of the positioning ring 3 on the temperature measuring guide rod 5, the positioning ring 3 is configured as a split structure, preferably a positioning ring 3 with two halves butted together to form an integral structure.

[0049] Furthermore, the bottom of the sleeve 2 has an arc-shaped inward buckle structure 12, which is extended from the end of the sleeve 2 to the axial center line of the sleeve 2, and the middle of the arc-shaped inward buckle structure 12 has a space for the temperature measuring guide rod 5 to pass through. By setting the arc-shaped inward buckle structure 12, the positioning ring 3 can be limited so that the positioning ring 3 will not fall out of the sleeve 2 when it moves to the bottom of the sleeve 2.

[0050] The clamp flange 4 is fixed to the top of the flange cover 1 by eyebolts 6. The clamp flange 4 is evenly distributed with a number of mounting holes, and the positions and numbers of the holes correspond to the screw holes on the flange cover 1. The eyebolts 6 are passed through the mounting holes of the clamp flange 4 and the screw holes of the flange cover 1 to fix the clamp flange 4 to the flange cover 1. In a preferred solution, four mounting holes are provided on the clamp flange 4.

[0051] Specifically, Figure 2 As shown, the clamp flange 4 is a split structure, preferably set to two petals, of course, it can also be multi-petals. That is, the clamp flange 4 includes a multi-petal split flange, the shape of the split flange is adjusted according to the number of petals, the multi-petal split flange is spliced ​​to form a circular ring structure, and the adjacent petal split flanges are fixedly connected.

[0052] Locking blocks 7 are fixedly arranged on both sides of the split flange, and the locking blocks 7 of the adjacent petal split flanges are fastened and connected by locking bolts 8. Specifically, a through hole is arranged in the locking block 7, and the locking bolts 8 are inserted into the through hole of the locking block 7 to connect the adjacent petal split flanges.

[0053] In this embodiment, two split flanges are provided. The two split flanges have the same shape, both of which are semicircular. Two locking blocks 7 are provided on each split flange, and the locking blocks 7 are connected by locking bolts 8.

[0054] A through hole is provided in the middle of the clamp flange 4 for the temperature measuring guide rod 5 to pass through, and a sealing ring 9 is provided at the through hole in the middle of the clamp flange 4. The sealing ring 9 adopts a metal ring gasket, which can provide a large pre-tightening force, realize sealing, and prevent the temperature measuring guide rod 5 from shaking. Specifically, a sealing ring groove is provided inside the through hole in the middle of the clamp flange 4, and the sealing ring 9 is placed in the sealing ring groove.

[0055] In an optional implementation scheme, sealing gaskets are arranged between the flange cover 1 and the equipment flange 10 and between the flange cover 1 and the clamping flange 4 to improve the overall airtightness of the device.

[0056] The method of using the device is:

[0057] During installation, first insert the sealing ring 9 into the temperature measuring guide rod 5, and then fix the positioning ring 3. The positioning ring 3 can be fixed to the temperature measuring guide rod 5 by welding (a groove is provided on the temperature measuring guide rod 5, and the positioning ring 3 is a two-half structure. During assembly, the positioning ring 3 is stuck in the groove and the positioning ring 3 is welded and fixed firmly);

[0058] Then, insert the sleeve 2 from the bottom of the temperature measuring guide rod 5 and weld it to the flange cover 1. After adjusting the position of the sealing ring 9, first fix the clamping flange 4 to the temperature measuring guide rod 5 with the locking bolts 8, and then fix the clamping flange 4 to the top of the flange cover 1 with the eye bolts 6 to achieve sealing. In order to improve the airtightness, sealing gaskets are set between the flange cover 1 and the equipment flange 10, and between the flange cover 1 and the clamping flange 4.

[0059] When the temperature measuring depth needs to be adjusted, it is only necessary to loosen the locking bolt 8 and the eye bolt 6, adjust the insertion depth of the temperature measuring guide rod 5 up and down to a suitable position, and then tighten the locking bolt 8 and the eye bolt 6.
