Description

Technical Field

[0001] This invention relates to the field of multi-stage heating reaction equipment, and more particularly to a multi-stage heating reaction equipment for terpineol. Background Technology

[0002] Terpineol is an important fragrance and industrial solvent, typically produced by the hydration reaction of α-pinene in turpentine oil in the presence of an acidic catalyst. This reaction requires extremely precise temperature control, and traditional single-stage heating reactors are prone to side reactions, affecting product yield and purity. This multi-stage heating reactor aims to solve this problem.

[0003] In existing multi-stage heating reaction equipment, during the heating process, terpineol partially vaporizes as the temperature rises, causing the internal pressure of the heating tank to increase. Conventional pressure relief methods are slow and ineffective for rapidly rising pressure. Furthermore, the gas released during pressure relief contains the vaporized terpineol, which leads to raw material loss and reduces the usability of the multi-stage heating reaction equipment. Summary of the Invention

[0007] In a preferred embodiment, the heating tank has a feed hole at the top, and a feed pipe is fixedly connected inside the feed hole. A feed valve is connected to the outer wall of the feed pipe via a flange, and a fixed-point pointing cylinder is fixedly connected to the bottom of the feed pipe.

[0008] In a preferred embodiment, the heating tank is provided with a uniform introduction mechanism below the fixed-point pointing cylinder, and the uniform introduction mechanism includes a jacket, which is fixedly connected to the inner wall of the heating tank. Two fixing rods are fixedly connected to the inner wall of the heating tank below the jacket, and the top of the two fixing rods is fixedly connected to the same inner filling ring frame.

[0009] In a preferred embodiment, a drive motor is fixedly connected to the bottom inner wall of the inner filling ring frame, and the output shaft of the drive motor is fixedly connected to a rotating shaft via a coupling. A guide cone is fixedly connected to the top of the rotating shaft, the bottom of the guide cone is in contact with the top of the inner filling ring frame, a guide groove is opened on the arc surface of the guide cone, a fixed-point pointing cylinder is located above the guide groove, an annular slide rail is fixedly connected to the inner side wall of the inner filling ring frame, a reinforcing ring plate is slidably connected inside the annular slide rail, and the reinforcing ring plate is fixedly connected to the outer side wall of the rotating shaft.

[0010] In a preferred embodiment, the bottom of the guide cone is provided with a ring of fixed plates, and the bottom of each fixed plate is connected to a rotating shaft via a bearing. Each rotating shaft has a rotating blade fixedly connected at equal intervals on its outer side wall. The top of the jacket is provided with a ring of mounting rods, and the bottom of each mounting rod is fixedly connected to a mating rod, which is mounted on the rotation trajectory of the rotating blades.

[0011] In a preferred embodiment, two mating arc plates are symmetrically distributed on the side wall near the bottom of the inner filling ring frame, and the outer side wall of the inner filling ring frame between the two mating arc plates is hinged to a material discharge arc plate. The material discharge arc plate fits against the side wall of the jacket. An integrated ring rod is fixedly connected to the side wall of the inner filling ring frame below the material discharge arc plate. Support springs are fixedly connected at equal intervals on the side of the integrated ring rod facing the adjacent material discharge arc plate, and one end of the support spring is fixedly connected to the arc surface of the material discharge arc plate.

[0012] In a preferred embodiment, the heating tank has two connection holes at the jacket, with a hot water outlet pipe fixedly connected inside the upper connection hole and a hot water inlet pipe fixedly connected inside the lower connection hole.

[0015] This invention provides a multi-stage heating reaction device for terpineol. During multi-stage heating of terpineol, the gas pressure inside the heating tank increases, causing the gas to impact a pressure ball. This compresses the adjusting spring rod, moving the pressure ball above two guide pipes. The gas then gradually flows through these pipes into the corresponding storage bladders. The initial shape of the storage bladders is twisted, and the gas flow is relatively slow at this stage. When the rate of pressure increase exceeds the gas transfer rate, the pressure ball is compressed again. This triggers the pressure sensor, activating the forward and reverse motors. The motors rotate and unfold the twisted storage bladders, rapidly expanding the internal space. Since the storage bladders are empty, the gas quickly flows into them, completing the pressure relief operation and ensuring the safety of the heating tank during operation.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The terpineol multi-stage heating reaction device disclosed in this invention is mainly applied to the use of existing multi-stage heating reaction devices. During the heating process, terpineol will vaporize a portion as the temperature rises, which will cause the internal pressure of the heating tank to increase. Conventional pressure relief methods are slow and have poor pressure relief effect for rapidly rising pressure. At the same time, the gas discharged during pressure relief contains the vaporized terpineol, which will cause raw material loss.

[0029] Reference Figures 1-10 A multi-stage heating reaction apparatus for terpineol includes a heating tank 1. An adjustable pressure relief protection mechanism 4 is provided near the top of the heating tank 1. The adjustable pressure relief protection mechanism 4 includes a mounting outer ring 403, which is fixedly connected to the outer side wall of the heating tank 1 near the top. Two mounting brackets 404 are symmetrically distributed on the mounting outer ring 403, and motor sleeves 402 are fixedly connected to each of the two mounting brackets 404. A forward and reverse reversing motor 405 is fixedly connected inside each of the two motor sleeves 402. A mating hole is provided on the outer side wall of the heating tank 1 below the mounting outer ring 403. The connection hole is fixedly connected to a connecting pipe 409. A pressure relief pipe 406 is connected to the connecting pipe 409 via a flange. The pressure relief pipe 406 has two guide holes in its upper part. A guide pipe 410 is fixedly connected to the inside of each of the two guide holes. A storage airbag 401 is sleeved on the outer wall of each of the two guide pipes 410. The output shafts of the two forward and reverse motors 405 are fixedly connected to rotating shafts 408 via couplings. A docking block 407 is fixedly connected to the opposite end of each of the two rotating shafts 408. The docking block 407 is fixedly connected to the outer wall of the adjacent storage airbag 401.

[0030] In a specific application scenario, during the multi-stage heating treatment of terpineol, the gas pressure inside the heating tank 1 increases, causing the gas to impact the pressure ball 411, which compresses the adjusting spring rod 413. The pressure ball 411 then moves above the two guide pipes 410, and the gas gradually flows through the two guide pipes 410 into the corresponding storage bladder 401. The initial shape of the storage bladder 401 is twisted, and at this time, the gas flow is relatively slow. When the rate of increase in gas pressure exceeds the rate of gas transfer, the pressure ball 411 is squeezed again, and the trigger rod 415 contacts the pressure sensor 414, activating the forward and reverse motor 405. The forward and reverse motor 405 drives the twisted storage bladder 401 to rotate and unfold, rapidly expanding the internal space of the storage bladder 401. Since there is no gas filling inside, the gas quickly flows into the storage bladder 401, completing the pressure relief operation and ensuring the safety of the heating tank 1 during operation.

[0031] Specifically, after the adjustable pressure relief protection mechanism 4 completes the pressure adjustment inside the heating tank 1, when the terpineol multi-stage heating is completed and it is in a cooling state, the pressure inside the heating tank 1 begins to decrease. At this time, the forward and reverse motor 405 starts to reverse, and the storage gas bag 401 in the collision state is gradually rotated into a twisted shape again. The gas inside is squeezed into the pressure relief pipe 406 again and flows back into the heating tank 1. When the pressure inside the heating tank 1 gradually stabilizes, the adjusting spring rod 413 drives the pressure ball 411 to reset. The gas initially discharged contains the vaporized part of terpineol, which is reintroduced into the heating tank 1 for cooling, reducing terpineol loss and improving the use value of the multi-stage heating reaction equipment.

[0032] Reference Figures 1-6 In a preferred embodiment, the pressure relief pipe 406 is filled with a pressure ball 411 between the two guide pipes 410, and the pressure ball 411 is in contact with the inner wall of the pressure relief pipe 406. An external block 412 is fixedly connected to the outer wall of the pressure ball 411 facing upward. An adjusting spring rod 413 is fixedly connected to the top of the external block 412. The top of the adjusting spring rod 413 is fixedly connected to the top inner wall of the pressure relief pipe 406. Pressure sensors 414 are fixedly connected to the top inner walls of the pressure relief pipe 406 on both sides of the adjusting spring rod 413. A trigger rod 415 is fixedly connected to the top of the external block 412 below the two pressure sensors 414.

[0033] Reference Figure 1 and Figure 3 In a preferred embodiment, the heating tank 1 has a feed hole at the top, and a feed pipe 3 is fixedly connected inside the feed hole. The outer wall of the feed pipe 3 is connected to a feed valve 2 via a flange, and a fixed-point pointing cylinder 10 is fixedly connected to the bottom of the feed pipe 3.

[0034] Reference Figure 1 , Figure 2 and Figure 7 In a preferred embodiment, the heating tank 1 is provided with a uniform introduction mechanism 9 below the fixed-point pointing cylinder 10, and the uniform introduction mechanism 9 includes a jacket 901. The jacket 901 is fixedly connected to the inner wall of the heating tank 1. Two fixing rods 907 are fixedly connected to the inner wall of the heating tank 1 below the jacket 901. The top of the two fixing rods 907 is fixedly connected to the same inner filling ring frame 908.

[0035] Reference Figures 7-9In a preferred embodiment, a drive motor 909 is fixedly connected to the bottom inner wall of the inner filling ring frame 908, and the output shaft of the drive motor 909 is fixedly connected to a rotating shaft 915 via a coupling. A guide cone 902 is fixedly connected to the top of the rotating shaft 915. The bottom of the guide cone 902 is in contact with the top of the inner filling ring frame 908. A guide groove 906 is opened on the arc surface of the guide cone 902. The fixed-point pointing cylinder 10 is located above the guide groove 906. An annular slide rail 916 is fixedly connected to the inner side wall of the inner filling ring frame 908. A reinforcing ring plate 914 is slidably connected inside the annular slide rail 916. The reinforcing ring plate 914 is fixedly connected to the outer side wall of the rotating shaft 915.

[0036] Specifically, during the introduction of terpineol, it is introduced onto the guide cone 902 through the fixed-point pointing cylinder 10. The drive motor 909 is started, and the drive motor 909 drives the guide cone 902 to rotate, thereby evenly distributing it to various positions of the jacket 901, improving the uniformity of terpineol introduction and thus improving the uniformity of its heating. At the same time, during the rotation of the guide cone 902, it drives each flipping blade 913 to rotate around the inner filling ring 908. During the rotation of the large direction, the flipping blade 913 comes into contact with the mating rod 904, and the two collide. Then, the rotation shaft 911 rotates, causing the flipping blade 913 to separate from the mating rod 904. During this process, the flipping blade 913 flips the terpineol located between the jacket 901 and the inner filling ring 908, so that the terpineol can contact the jacket 901, further improving the initial heating uniformity of the terpineol.

[0037] It should be noted that as the amount of terpineol inside the jacket 901 and the inner filling ring 908 gradually increases, the terpineol squeezes the feeding arc plate 912 and compresses the support spring 917. The terpineol located below is then gradually introduced into the space below the heating tank 1 through the feeding arc plate 912, avoiding excessive contact between the terpineol and the jacket 901, which would lead to overheating. This controls the heating time of the terpineol between the jacket 901 and the inner filling ring 908, thereby improving the temperature control effect.

[0038] Reference Figures 7-9 In a preferred embodiment, the bottom of the guide cone 902 is provided with a ring of fixed plates 903, and the bottom of each fixed plate 903 is connected to a rotating shaft 911 via a bearing. The outer side wall of each rotating shaft 911 is fixedly connected with a rotating blade 913 at equal intervals. The top of the jacket 901 is provided with a ring of mounting rods 905, and the bottom of each mounting rod 905 is fixedly connected with a mating rod 904. The mating rod 904 is installed on the rotation trajectory of the rotating blade 913.

[0039] Reference Figures 7-9In a preferred embodiment, two mating arc plates 910 are symmetrically distributed on the side wall near the bottom of the inner filling ring frame 908, and the outer side wall of the inner filling ring frame 908 between the two mating arc plates 910 is hinged to a material discharge arc plate 912. The material discharge arc plate 912 fits against the side wall of the jacket 901. An integrated ring rod 918 is fixedly connected to the side wall of the inner filling ring frame 908 below the material discharge arc plate 912. Support springs 917 are fixedly connected at equal intervals on the side of the integrated ring rod 918 facing the adjacent material discharge arc plate 912. One end of the support spring 917 is fixedly connected to the arc surface of the material discharge arc plate 912.

[0040] Reference Figure 1 and Figure 2 In a preferred embodiment, the heating tank 1 has two connection holes at the jacket 901, and a hot water outlet pipe 8 is fixedly connected inside the connection hole located at the upper position, while a hot water inlet pipe 7 is fixedly connected inside the connection hole located at the lower position.

[0041] Reference Figure 2 In a preferred embodiment, a fixing bracket 6 is fixedly connected to the outer wall of the heating tank 1, and a discharge hole is opened at the bottom of the heating tank 1. A discharge pipe 12 is fixedly connected inside the discharge hole, and a discharge valve 13 is connected to the outer wall of the discharge pipe 12 through a flange.

[0042] Reference Figure 1 , Figure 2 , Figure 3 and Figure 10 In a preferred embodiment, a coil 11 is fixedly connected to the inner wall of the heating tank 1 near the lower half. The coil 11 has mounting holes at both the top and bottom. A heat transfer oil outlet pipe 5 is fixedly connected to the upper mounting hole, and a heat transfer oil inlet pipe 14 is fixedly connected to the lower mounting hole. A stirring motor 16 is fixedly connected to the bottom of the inner filling ring 908. The output shaft of the stirring motor 16 is fixedly connected to a stirring shaft 17 via a coupling. Stirring blades 15 are fixedly connected at equal intervals to the outer wall of the stirring shaft 17 between the coils 11. A support base 19 is fixedly connected to the bottom of the stirring shaft 17. Two inner connecting rods 18 are fixedly connected to the bottom of the support base 19. Both inner connecting rods 18 are fixedly connected to the inner wall of the heating tank 1.

[0043] Working principle: During use, hot water is introduced into the space between the jacket 901 and the heating tank 1 through the hot water inlet pipe 7, and discharged through the hot water outlet pipe 8, forming a hot water circulation. Similarly, heat transfer oil is added to the coil 11 through the heat transfer oil inlet pipe 14 and discharged through the heat transfer oil outlet pipe 5, forming a heat transfer oil circulation. The feed valve 2 is opened, and terpineol flows through the feed pipe 3 to the fixed-point guiding cylinder 10, then is introduced onto the guide cone 902. The drive motor 909 is started, causing the guide cone 902 to rotate, thereby evenly distributing the terpineol to various positions in the jacket 901, improving the uniformity of terpineol introduction, and thus improving the uniformity of heating. Simultaneously... During the rotation of the guide cone 902, it drives each flipping blade 913 to rotate around the inner filling ring 908. During the large-direction rotation, the flipping blade 913 contacts the mating rod 904, causing a collision. The rotating shaft 911 then rotates, causing the flipping blade 913 to separate from the mating rod 904. During this process, the flipping blade 913 agitates the terpineol located between the jacket 901 and the inner filling ring 908, ensuring that the terpineol can contact the jacket 901. During the initial heating process, if the gas pressure inside the heating tank 1 rises, the gas impacts the pressure ball 411, causing the adjusting spring rod 413 to compress. The pressure ball 411... 1. Moved above the two guide tubes 410, the gas gradually flows through the two guide tubes 410 into the corresponding storage bladder 401. The initial shape of the storage bladder 401 is twisted. At this time, the gas flow is relatively slow. When the rate of increase in gas pressure is greater than the rate of gas transfer, the pressure ball 411 is squeezed again. The trigger rod 415 contacts the pressure sensor 414, activating the forward and reverse motor 405. The forward and reverse motor 405 drives the twisted storage bladder 401 to rotate and unfold. The internal space of the storage bladder 401 expands rapidly, and since there is no gas filling inside, the gas flows rapidly into the storage bladder 401, completing the depressurization operation. When located at the jacket 90... As the amount of terpineol inside the inner filling ring 908 gradually increases, the terpineol squeezes the discharge arc plate 912 and compresses the support spring 917. The terpineol located below is then gradually introduced into the space below the heating tank 1 through the discharge arc plate 912. The heat transfer oil inside the coil 11 reheats the terpineol. At the same time, the stirring motor 16 is started, and the stirring motor 16 drives the stirring blades 15 on the stirring shaft 17 to stir the terpineol, so that it is heated evenly. After the terpineol is heated, the circulation of hot water and heat transfer oil is stopped, and it begins to cool in the heating tank 1. After cooling is completed, the discharge valve 13 is opened, and it is discharged through the discharge pipe 12, ending the operation.
