Description

Technical Field

[0001] This invention relates to a temperature control processor for synthesizing chemical materials, belonging to the field of chemical engineering. Background Technology

[0002] In the field of synthetic chemical materials, temperature has always been a core factor influencing the progress of chemical reactions, as well as the quality and performance of products. Whether in meticulous laboratory research or large-scale industrial production, precise temperature control plays an indispensable role.

[0003] Thermocouple temperature sensors, as an important component of temperature control processors, play a crucial role in temperature monitoring. The junction box of these sensors typically has a protective sleeve installed at the bottom to enclose and protect the internal thermocouple wires from the high temperatures, corrosive media, or mechanical impacts within the reactor. The other end of the protective sleeve features a special connection structure composed of a hexahedron and an externally threaded post. Using the force-bearing surface of the hexahedron, the externally threaded post can be screwed into the corresponding threaded hole in the reactor using a tool, thus completing a secure assembly between the protective sleeve and the reactor.

[0004] However, this fixed threaded connection method has certain limitations: once the position of the mounting screw holes on the reactor is fixed, the orientation of the protective sleeve and the junction box connected to it is also determined. But in practical applications, the cable routing path is often limited by factors such as site space and equipment layout (e.g., there may be obstacles such as pipes and supports around the reactor), which can easily lead to a situation where the orientation of the conduit on the junction box forms an angle with the natural routing path of the cable. In this case, the end of the cable near the junction box has to be bent to adapt to the connection requirements. Long-term bending may not only cause the copper core inside the cable to break or the insulation layer to be damaged, affecting the stable transmission of temperature signals, but may also accelerate cable aging due to stress concentration, shorten the service life of the sensor, and pose a hidden danger to the reliability of temperature monitoring. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a temperature control processor for synthesizing chemical materials, so as to solve the problems mentioned in the background art. After the protective sleeve is threadedly connected to the reactor, the orientation of the conduit on the junction box can be adjusted as needed.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a temperature control processor for synthesizing chemical materials, comprising: A junction box, the outer surface of which is fitted with a conduit, and a boss is fitted at the bottom of the junction box; A thermocouple, the upper end of which is installed inside a junction box, with one end of the thermocouple passing through a boss and extending to the lower side of the junction box; A protective sleeve is fitted onto the thermocouple. A first hexahedron is mounted on the lower end of the protective sleeve, and a hollow first externally threaded post is mounted on the lower surface of the first hexahedron. Both the first hexahedron and the first externally threaded post are fitted onto the thermocouple. A limiting ring is mounted on the upper end of the protective sleeve, and the limiting ring is inserted into a boss. The second hexahedron is fitted onto the protective sleeve. The upper end of the protective sleeve is fitted with a hollow second external threaded post. The second external threaded post is installed on the side of the second hexahedron that is away from the first hexahedron. The second external threaded post is threaded into the boss.

[0007] Furthermore, the side of the boss facing away from the junction box is recessed to form a rectangular groove, a rectangular block is inserted in the rectangular groove, a threaded hole is opened on one side of the rectangular block, the second external threaded post is threaded into the threaded hole, the rectangular block is installed in the rectangular groove by a limiting screw, and the outer diameter of the limiting ring is the same as the inner diameter of the threaded hole.

[0008] Furthermore, threaded blind holes are machined on both parallel sides of the rectangular block, and four planes are machined on the outer surface of the boss. Small holes that mate with the threaded blind holes are opened on both parallel planes. One end of the limiting screw passes through the small hole and is threaded into the threaded blind hole.

[0009] Furthermore, the end of the junction box away from the boss is open, and the open end of the junction box is provided with a cover. The cover is rotatably connected to the conduit via a pin, and the end of the cover away from the pin is connected to the junction box via a connecting screw.

[0010] Furthermore, a through hole is provided at the top of the boss, the through hole is connected to the internal space of the junction box, and the upper end of the thermocouple passes through the through hole.

[0011] Furthermore, the first hexahedron and the first external threaded post are integrally formed, and the second hexahedron and the second external threaded post are integrally formed.

[0012] Furthermore, the boss and the junction box are integrally formed, and the conduit and the junction box are integrally formed.

[0013] Furthermore, a sealing ring is provided on the side of the limiting ring away from the protective sleeve, and the sealing ring is fitted onto the thermocouple.

[0014] The beneficial effects of this utility model are: 1. After the protective sleeve is fixed to the reactor via the first external threaded post, the junction box can be oriented by rotatable connection between the boss and the protective sleeve. Specifically, the limiting ring at the upper end of the protective sleeve is embedded in the boss, and the second external threaded post initially fixes the boss and the protective sleeve via a threaded connection. Loosening the structure formed by the second hexahedron and the second external threaded post allows the boss to rotate around the protective sleeve, causing the junction box and conduit to rotate synchronously until the conduit's orientation aligns with the cable routing path. Then, the second external threaded post is tightened again to fix the angle. Regardless of whether there are obstacles such as pipes or supports around the reactor restricting the cable path, or whether the wiring needs to be routed in a specific direction, the cable can be naturally extended by adjusting the orientation of the conduit. This avoids the forced bending of the cable near the junction box end in traditional fixed structures, reducing the risk of copper core breakage and insulation damage, and ensuring stable temperature signal transmission.

[0015] 2. Install the rectangular block with the threaded hole into the rectangular groove on the boss using the limiting screw to assemble the rectangular block and the boss. This allows the second external threaded post to be threaded into the threaded hole, thus limiting the relative position of the protective sleeve and the junction box. There is no need to machine a threaded hole on the boss to match the second external threaded post. When the threaded hole is damaged, only the rectangular block needs to be replaced. There is no need to replace the junction box when the thread is damaged. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a temperature control processor for synthesizing chemical materials, including a junction box 1, a conduit 12 installed on the outer surface of the junction box 1, the conduit 12 and the junction box 1 being an integrally formed structure, the end of the junction box 1 away from the boss 11 being open, the open end of the junction box 1 being provided with a cover 13, the cover 13 being rotatably connected to the conduit 12 by a pin, the end of the cover 13 away from the pin being connected to the junction box 1 by a connecting screw, the cover 13 and the junction box 1 forming a closed wiring space.

[0019] See Figures 1-4 A boss 11 is installed at the bottom of the junction box 1. The boss 11 and the junction box 1 are integrally formed. The upper end of the thermocouple 3 is installed inside the junction box 1. A through hole is opened at the top of the boss 11, which communicates with the internal space of the junction box 1. The upper end of the thermocouple 3 passes through the through hole. One end of the thermocouple 3 passes through the boss 11 and extends to the lower side of the junction box 1. A protective sleeve 2 is fitted on the thermocouple 3. A first hexahedron 21 is installed at the lower end of the protective sleeve 2. A hollow first external threaded post 22 is installed on the lower surface of the first hexahedron 21. The first hexahedron 21 and the first external threaded post 22 are integrally formed. The first hexahedron 21 and the first external threaded post 22 are both fitted on the thermocouple 3. The lower end of the protective sleeve 2 forms a firm threaded connection with the reactor through the combination structure of the first hexahedron 21 and the first external threaded post 22, ensuring that the sensor does not loosen in high temperature and vibration environments (such as the stirring process of the reactor).

[0020] See Figures 1-4A limiting ring 23 is installed at the upper end of the protective sleeve 2. The limiting ring 23 is inserted into the boss 11. The second hexahedron 5 is sleeved on the protective sleeve 2. A hollow second external threaded post 51 is sleeved at the upper end of the protective sleeve 2. The second external threaded post 51 is installed on the side of the second hexahedron 5 that is away from the first hexahedron 21. The second hexahedron 5 and the second external threaded post 51 are integrally formed. The second external threaded post 51 is threadedly connected to the boss 11. After the protective sleeve 2 is fixed to the reactor through the first external threaded post 22, the junction box 1 can adjust its direction by means of the rotatable connection between the boss 11 and the protective sleeve 2. The specific operation process is as follows: The limiting ring 23 at the upper end of the protective sleeve 2 is embedded in the boss 11. The second external threaded post 51 achieves the initial fixation of the boss 11 and the protective sleeve 2 through the threaded connection. If the direction needs to be adjusted, simply loosen the combination structure composed of the second hexahedron 5 and the second external threaded post 51. At this time, the boss 11 can rotate freely around the protective sleeve 2, thereby driving the junction box 1 and the conduit 12 to rotate synchronously. After the orientation of the conduit 12 is completely consistent with the cable laying path, the second external threaded post 51 is tightened again to complete the angle fixation.

[0021] Whether the cable routing path is restricted by obstacles such as pipes and supports around the reactor, or it is necessary to achieve neat wiring in a specific direction, the cable can be allowed to extend naturally by adjusting the orientation of the conduit 12. This avoids the problem of the cable being forced to bend at the end near the junction box 1, which occurs in traditional fixed structures. This reduces the possibility of copper core breakage and insulation layer damage inside the cable, ensuring that the temperature signal can be transmitted stably.

[0022] See Figures 1-3 The boss 11 has a recessed rectangular groove 16 on the side facing away from the junction box 1. A rectangular block 6 is inserted into the rectangular groove 16. A threaded hole 61 is opened on one side of the rectangular block 6. A second external threaded post 51 is threaded into the threaded hole 61. The rectangular block 6 is installed in the rectangular groove 16 by a limiting screw 4. The outer diameter of the limiting ring 23 is the same as the inner diameter of the threaded hole 61. Threaded blind holes 62 are machined on two parallel sides of the rectangular block 6. Four planes 14 are machined on the outer surface of the boss 11. Each of the two parallel planes 14 has a threaded blind hole 62 that mates with the threaded blind hole 62. A small hole 15 is formed, and one end of the limiting screw 4 passes through the small hole 15 and is threaded into the threaded blind hole 62. A sealing ring 7 is provided on the side of the limiting ring 2 away from the protective sleeve 2. The sealing ring 7 is fitted onto the thermocouple 3. After the second external threaded post 51 is screwed into the threaded hole 61, the sealing ring 7 is pressed by the limiting ring 23 into the threaded hole 61 near the through hole. The rectangular block 6 with the threaded hole 61 is placed into the rectangular groove 16 of the boss 11, and then the rectangular block 6 is fixed in the rectangular groove 16 with the limiting screw 4, thus completing the assembly of the rectangular block 6 and the boss 11. At this time, the second external threaded post 51 on the protective sleeve 2 can be screwed into the threaded hole 61 of the rectangular block 6, thereby limiting the relative position of the protective sleeve 2 and the junction box 1.

[0023] This design eliminates the need to directly machine the threaded hole 61 that matches the second external threaded post 51 on the boss 11. When the threaded hole 61 on the rectangular block 6 is worn or damaged due to long-term use, only the rectangular block 6 needs to be replaced. Unlike the traditional structure, the junction box 1 does not need to be replaced as a whole when the thread is damaged, which greatly reduces maintenance costs and replacement difficulty.
