Description

Technical Field

[0001] This utility model relates to the field of reaction technology, specifically to a rotary tube reaction device. Background Technology

[0002] A tubular reactor is a continuous-operation reactor with a tubular shape and a large length-to-diameter ratio. Due to its low backmixing and high volumetric efficiency, it is widely used in fine chemicals, pharmaceuticals and other fields.

[0003] In the prior art, a rotary tube reactor with publication number "CN 221638137 U" utilizes the cooperation of a rotating rod and a mixing rack. When the rotating rod rotates inside the reaction cylinder, the mixing rack and mixing rod rotate along with it. The mixing rack stirs the materials, accelerating the reaction process and making the reaction more complete. Simultaneously, the mixing rack's movement allows it to adhere to the inner wall of the reaction cylinder, scraping away any adhering substances. This ensures the reaction effect and facilitates subsequent cleaning. Combined with a temperature control system, the material undergoes mass transfer, mixing, nucleation, crystallization, dissolution, dispersion, and emulsification during the enhanced reaction, resulting in a faster reaction rate and higher efficiency.

[0004] However, in the aforementioned patent, the mixing rack is in direct contact with the reaction cylinder. In actual use, both the mixing rack and the reaction cylinder are made of metal, which causes friction during the mixing process. Long-term operation can easily lead to wear on both, affecting the scraping effect and the life of the equipment. Utility Model Content

[0005] To address the shortcomings of the existing technology, this invention proposes a rotary cutting tube reaction device.

[0006] To achieve the above-mentioned technical effects, the present invention adopts the following solution: A rotary tube reaction apparatus, comprising: The reaction cylinder has a reaction chamber inside. One end of the reaction chamber passes through the reaction cylinder and has an end sealing plate for sealing the reaction chamber at the through end. The end sealing plate is detachably connected to the reaction cylinder. The end of the reaction chamber away from the end sealing plate is connected to a feed port on the outer wall of the reaction cylinder. The end sealing plate has a discharge port that communicates with the reaction chamber. A mixing rack, located inside a reaction chamber, includes a horizontally arranged rotating rod. One end of the rotating rod is connected to a drive assembly, and the other end of the rotating rod is rotatably connected to an end sealing plate. Multiple mixing rods are arranged around the rotating rod and are attached to the inner wall of the reaction chamber. The mixing rods are arranged parallel to the rotating rod and are connected to the rotating rod through several connecting rods. Wear-resistant scrapers are located on the side of the mixing rod that is in contact with the inner wall of the reaction chamber.

[0007] In a preferred embodiment, the wear-resistant scraper is detachably mounted on the mixing rod. The mixing rod has a slot extending along its length on the side facing the inner wall of the reaction chamber. The wear-resistant scraper is attached to the outer side of the mixing rod and has a protruding insertion part that is embedded in the slot. The insertion part matches the slot.

[0008] In a preferred embodiment, the wear-resistant scraper is made of polytetrafluoroethylene or a ceramic composite material.

[0009] In a preferred embodiment, the drive assembly includes a motor mounted on the outer wall of the reaction cylinder. The motor is located at the other end of the end sealing plate connecting the reaction cylinder. A through hole communicating with the reaction chamber is provided on the outer wall of the reaction cylinder. The output end of the motor extends into the reaction chamber through the through hole, and the output end of the motor is rotatably connected to the through hole through a shaft seal structure. The output end of the motor is connected to a rotating rod through a coupling.

[0010] In a preferred embodiment, the coupling is a plum blossom-shaped flexible coupling.

[0011] In a preferred embodiment, the reaction cylinder is further provided with a heat-conducting oil chamber surrounding the reaction chamber. The upper end of the reaction cylinder near the feed inlet is provided with an oil inlet communicating with the heat-conducting oil chamber, and the lower end of the reaction cylinder near the end sealing plate is provided with an oil outlet communicating with the heat-conducting oil chamber.

[0012] In a preferred embodiment, the reaction cylinder is provided with multiple temperature measuring components, each including a temperature sensor and a probe. A groove is formed at the bottom of the reaction chamber, and a heat-conducting cover plate is fitted into the groove. The upper end of the heat-conducting cover plate is flush with the bottom of the reaction chamber. The probe of the temperature sensor is attached to the lower end of the heat-conducting cover plate. A heat insulation pipe passes through the heat-conducting oil cavity, and the wire connecting the probe and the temperature sensor passes through the heat-conducting oil cavity from the heat insulation pipe.

[0013] Compared with existing technologies, the beneficial effects are: This invention has a simple structure and is easy to use. The mixing rod contacts the inner wall of the reaction chamber through a wear-resistant scraper, which protects the mixing rack and the inner wall of the reaction cylinder while ensuring the scraping effect, reducing maintenance costs and extending the service life of the equipment.

Multiple mixing rods 202 are arranged around the rotating rod 201 and are attached to the inner wall of the reaction chamber 101. The mixing rods 202 are arranged parallel to the rotating rod 201 and are connected to the rotating rod 201 through several connecting rods 203.

[0024] The wear-resistant scraper 204 is located on the side of the mixing rod 202 that is in contact with the inner wall of the reaction chamber 101.

[0025] The material is fed into the reaction chamber 101 through the feed inlet 103. The mixing rack 20 rotates under the drive of the drive assembly 40, thereby mixing the material. The mixing rod 202 is in contact with the reaction chamber 101 and can scrape off the material adhering to the inner wall of the reaction chamber 101. The mixing rod 202 contacts the inner wall of the reaction chamber 101 through the wear-resistant scraper 204. While ensuring the scraping effect, it protects the mixing rack 20 and the inner wall of the reaction cylinder 10, reduces maintenance costs, and extends the service life of the equipment.

[0026] In a preferred embodiment, the wear-resistant scraper 204 is detachably mounted on the mixing rod 202. The mixing rod 202 has a slot 2021 extending along its length on the side facing the inner wall of the reaction chamber 101. The wear-resistant scraper 204 is attached to the outer side of the mixing rod 202 and protrudes to have a plug-in part 2041 that is embedded in the slot 2021. The plug-in part 2041 matches the slot 2021.

[0027] The wear-resistant scraper 204 can be inserted into the slot 2021 from one end of the mixing rod 202 via the plug part 2041, making it easy to replace the wear-resistant scraper 204.

[0028] In a preferred embodiment, the wear-resistant scraper 204 is made of polytetrafluoroethylene or ceramic composite material, which has both wear resistance and self-lubricating properties.

[0029] In a preferred embodiment, the drive assembly 40 includes a motor 401 mounted on the outer wall of the reaction cylinder 10.

The lower end of the reaction cylinder 10 is provided with an oil outlet 107 communicating with the heat-conducting oil cavity 105 near the end sealing plate 102.

[0032] The heat transfer oil is introduced through the inlet 106, and then discharged from the outlet 107 after passing through the heat transfer oil chamber 105. Through the heating of the heat transfer oil, the material undergoes mass transfer, mixing, nucleation, crystallization, dissolution, dispersion and emulsification in the enhanced reaction.

[0033] In a preferred embodiment, the reaction cylinder 10 is provided with a plurality of temperature measuring components 50, each temperature measuring component 50 including a temperature sensor 501 and a probe 5011.
