Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, specifically relating to a temperature control component for a biphenyl and biphenyl ether heat transfer oil production reactor. Background Technology

[0002] In the production of biphenyl and diphenyl ether heat transfer oil, temperature control is crucial for ensuring product quality, reaction stability, and process safety. Because biphenyl and diphenyl ether heat transfer oil typically exhibits high thermal stability and good thermal conductivity, precise temperature control is required during production to achieve the desired chemical reaction effect. Existing temperature control components primarily rely on external jackets and steam pipes, resulting in slow temperature adjustment rates that affect the reaction process in the reactor. Furthermore, most existing devices regulate reactor temperature through external circulation components, but the complex internal annular structure and the reactor's inherent wall thickness can prevent the timely absorption of excessive reaction heat or the timely provision of the necessary heat, thus reducing the overall reaction efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a temperature control component for a biphenyl and biphenyl ether heat transfer oil production reactor to solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a temperature regulating component for a biphenyl and biphenyl ether heat transfer oil production reactor, wherein multiple supports are arranged in a ring array at the bottom of the equipment body, and a discharge pipe is opened in the middle of the multiple supports; a mixing chamber is opened inside the equipment body; inlets are symmetrically arranged on both sides of the top of the equipment body; a mixing component is arranged in the middle of the inlets on both sides, and the mixing component penetrates the equipment body and is arranged in the mixing chamber; a liquid exchange tank is arranged on one side of the equipment body; a hot circulation pipe and a cold circulation pipe are connected to one side of the liquid exchange tank, and both the hot circulation pipe and the cold circulation pipe are arranged inside the mixing chamber; a control component is arranged at the connection between the hot circulation pipe and the cold circulation pipe and the equipment body, and the control component is arranged on a fixed frame.

[0005] Preferably, the control component includes a drive motor mounted on a fixed frame, a drive gear connected to the output end of the drive motor, a seal on one side of the drive gear, and the seals are respectively mounted on the hot circulation pipe and the cold circulation pipe. The drive gear drives the seal to control the flow and disconnection of the hot circulation pipe and the cold circulation pipe.

[0006] Preferably, the sealing element includes a driven wheel, a sealing plate, and a fixed wheel. Both the hot circulation pipe and the cold circulation pipe are provided with driven wheels, which are arranged opposite to each other. The driven wheels have a ring of driving grooves arranged in a row. A sealing plate is provided on one side of the driven wheel, and a driving post is provided on one side of the sealing plate. The driving post is slidably disposed with the driving groove. A limiting rod is provided on the other side of the sealing plate. The limiting rod is disposed on a limiting groove opened on the fixed wheel on one side of the sealing plate, and is slidably disposed with the limiting groove. Both the driven wheel and the fixed wheel have flow holes, and the diameter of the flow holes is the same as the diameter of the hot circulation pipe and the cold circulation pipe.

[0007] Preferably, the width of the drive gear depends on the distance between the driven gears on the hot circulation pipe and the cold circulation pipe.

[0008] Preferably, each of the multiple sealing plates is provided with a flow guide groove, so that when the temperature regulating medium passes through the flow guide groove on the sealing plate, the temperature regulating medium can flow along the surface of the flow guide groove.

[0009] The technical effects and advantages of this utility model are as follows: In the production process of biphenyl and biphenyl ether heat transfer oil, the raw materials are first added to the reactor. Then, the raw materials are mixed by the mixing components set in the mixing chamber. During the heating reaction, the drive motor rotates, which drives the drive gear at the output end to rotate. The drive gear drives the seals on the hot circulation pipe and the cold circulation pipe to move, allowing the heating medium to enter the mixing chamber through the hot circulation pipe and simultaneously closing the cold circulation pipe. When the temperature inside the mixing chamber is too high, the temperature sensor controls the drive motor to reverse. The drive motor rotates, which drives the drive gear at the output end to rotate. The drive gear drives the seals on the hot circulation pipe and the cold circulation pipe to move. At this time, the seals close the hot circulation pipe, preventing the heating medium from entering the mixing chamber through the hot circulation pipe. At the same time, the cold circulation pipe is allowed to circulate, allowing the cooling medium to enter the mixing chamber through the cold circulation, thereby reducing the temperature inside the reactor. This effectively controls the temperature inside the mixing chamber of the reactor, ensuring the overall reaction efficiency of the reactor. At the same time, the guide groove on the sealing plate can prevent the heating and cooling media from passing through the sealing plate at excessive speed, which could lead to damage to the sealing plate after long-term use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figures 1 to 6 The temperature control component of a biphenyl and biphenyl ether heat transfer oil production reactor shown has multiple supports 11 arranged in a ring array at the bottom of the equipment body 1, and a discharge pipe 14 is opened in the middle of the multiple supports 11. A mixing chamber is opened inside the equipment body 1. The top of the equipment body 1 has symmetrically arranged feed inlets 12 on both sides. A mixing component 13 is arranged in the middle of the feed inlets 12 on both sides and passes through the equipment body 1 and is located in the mixing chamber. A liquid exchange tank 2 is arranged on one side of the equipment body 1. A hot circulation pipe 3 and a cold circulation pipe 4 are connected to one side of the liquid exchange tank 2. Both the hot circulation pipe 3 and the cold circulation pipe 4 are located inside the mixing chamber. A control component 5 is arranged at the connection between the hot circulation pipe 3 and the cold circulation pipe 4 and the equipment body 1, and the control component 5 is mounted on a fixed frame 15.

[0020] Specifically, the control component 5 includes a drive motor 51 mounted on the fixed frame 15. The output end of the drive motor 51 is connected to a drive gear 52. A seal 53 is provided on one side of the drive gear 52, and the seal 53 is respectively mounted on the hot circulation pipe 3 and the cold circulation pipe 4. The drive gear 52 drives the seal 53 to control the flow and disconnection of the hot circulation pipe 3 and the cold circulation pipe 4.

[0021] Specifically, the sealing element 53 includes a driven wheel 531, a sealing plate 533, and a fixed wheel 536. Both the hot circulation pipe 3 and the cold circulation pipe 4 are provided with driven wheels 531, and the driven wheels 531 on the hot circulation pipe 3 and the cold circulation pipe 4 are arranged opposite to each other. Drive grooves 532 are arranged in a ring on the driven wheel 531, and a sealing plate 533 is provided on one side of the driven wheel 531. A drive column 534 is provided on one side of the sealing plate 533, and the drive column 534 is slidably arranged with the drive groove 532. A limit rod 535 is provided on the other side of the sealing plate 533. The limit rod 535 is arranged on the limit groove 537 opened on the fixed wheel 536 on one side of the sealing plate 533, and the limit rod 535 is slidably arranged with the limit groove 537. Both the driven wheel 531 and the fixed wheel 536 are provided with flow holes 538, and the diameter of the flow holes 538 is the same as the diameter of the hot circulation pipe 3 and the cold circulation pipe 4.

[0022] Specifically, the width of the drive gear 52 depends on the distance between the driven gear 531 on the hot circulation pipe 3 and the cold circulation pipe 4.

[0023] Specifically, multiple sealing plates 533 are provided with flow guide grooves. When the temperature regulating medium passes through the flow guide grooves on the sealing plate 533, the temperature regulating medium can flow along the surface of the flow guide grooves.

[0024] Working principle and process: In the production process of biphenyl and biphenyl ether heat transfer oil, the raw materials are first added to the reactor. Then, the raw materials are mixed by the mixing component 13 in the mixing chamber. When it is necessary to heat the inside of the reactor, the drive motor 51 is started. The rotation of the drive motor 51 drives the drive gear 52 to rotate. The rotation of the drive gear 52 drives the driven wheel 531 to move synchronously. The rotation of the driven wheel 531 drives the drive column 534 on the sealing plate 533 to move in the drive groove 532. At this time, the limiting rod 535 on the other side of the sealing plate 533 moves in the limiting groove 537 on the fixed wheel 536. At this time, multiple sealing plates 533 unfold, and the heating medium flows into the reactor through the flow holes 538 on the driven wheel 531 and the fixed wheel 536. Due to the spiral distribution of the hot circulation pipe 3 and the cold circulation pipe 4 in the mixing chamber... The system is designed to uniformly heat the interior of the reactor. When the internal temperature of the reactor becomes too high, a temperature sensor detects the temperature. If the temperature exceeds a preset value, the drive motor 51 reverses. Since the driven wheels 531 on the hot and cold circulation pipes 3 and 4 are installed opposite each other, the reverse rotation of the drive motor 51 drives the driven wheels 531 on both the hot and cold circulation pipes 3 and 4 to rotate. At this time, the driven wheels 531 on the hot circulation pipe 3 cause multiple sealing plates 533 to contract and seal the hot circulation pipe 3, while the driven wheels 531 on the cold circulation pipe 4 cause the corresponding multiple sealing plates 533 to expand. This allows the cooling medium to circulate through the cold circulation pipe 4 inside the reactor, thereby cooling the interior of the reactor and preventing excessively high internal temperatures that could lead to over-reaction. This effectively controls the temperature inside the mixing chamber of the reactor and ensures the overall reaction efficiency of the reactor.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
