Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a bromotriazine compound reaction vessel that prevents wall adhesion. Background Technology

[0002] Bromotriazine compounds are white in appearance, have a large molecular weight and complex structure, and possess good thermal stability and electrical properties, as well as excellent light resistance. Unlike traditional bromine-based flame retardants, bromotriazine has a high initial decomposition temperature and an endothermic decomposition heat reduction mechanism. It does not contain free bromine. During production, the raw materials need to be added to a reaction vessel and hydrogen peroxide and bromine are added dropwise to carry out a bromination reaction.

[0003] When bromotriazine compounds undergo bromination, the high viscosity of the reactants (such as triazine derivatives and bromine) makes them prone to depositing and coking on the inner wall of the reactor, leading to uneven heat transfer, increased local overheating side reactions, and decreased product purity.

[0004] To address this issue, we propose a non-sticking brominated triazine compound reactor. Utility Model Content

[0005] The purpose of this invention is to provide a bromotriazine compound reaction vessel that prevents wall adhesion, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A reaction vessel for preventing the adhesion of brominated triazine compounds includes a vessel body. A lifting rod extends vertically through the inner and outer sides of the vessel body. One end of the lifting rod, extending into the vessel body, is fitted with a scraper ring via a connecting rod. The outer edge of the scraper ring is in close contact with the inner circumferential side wall of the vessel body, and an ultrasonic transducer is embedded in the scraper ring. The other end of the lifting rod extends out of the vessel body and is threadedly connected to a bevel gear ring. A bracket is mounted on the vessel body, and a motor and a bevel gear are mounted on the bracket. The bevel gear is perpendicularly meshed with the bevel gear ring. A guide sleeve is also mounted on the top side wall of the lifting rod via a connecting rod, and the guide sleeve is slidably connected to a guide rod on the vessel body.

[0008] In a further embodiment, the centerlines of the guide rod, the lifting rod, and the vessel body are all parallel to each other, and the surface of the guide rod is uniformly provided with scale lines along its length.

[0009] In a further embodiment, a telescopic sleeve is fitted around the part of the boom extending out of the vessel body, and the two ends of the telescopic sleeve are respectively connected to the vessel body and the support. A connecting cylinder is provided at the connection point between the vessel body and the support and the telescopic sleeve. The connecting cylinder is threadedly connected to the telescopic sleeve. A sealing ring is embedded on the inner wall of both ends of the telescopic sleeve, and the sealing ring fits against the end of the connecting cylinder.

[0010] In a further embodiment, the boom is hollow inside, and a diaphragm pump is connected to the top of the boom via a hose.

[0011] In a further embodiment, the vessel body is also equipped with a bromine dripping pipe and a hydrogen peroxide dripping pipe, and a dripping valve is installed at the connection between the bromine dripping pipe and the hydrogen peroxide dripping pipe and the vessel body.

[0012] In a further embodiment, a temperature sensor is embedded in the surface of the connecting rod, and the temperature sensor is electrically connected to a control box installed on the vessel body.

[0013] In a further embodiment, the vessel body is also equipped with an active sealing system, which includes a vacuum pump, an exhaust pipe, a pressure compensation valve, a nitrogen pipe, and a pressure sensor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, through the setting of a motor-driven bevel gear and bevel ring rotating and meshing, causes the lifting rod to move up and down under the action of the thread with the bevel ring and the sliding limit action of the guide rod and guide sleeve, thereby driving the scraper ring to move up and down close to the reactor wall to remove deposits. At the same time, it can also use the cavitation effect of the ultrasonic transducer to break up the coking layer, reducing the problems of uneven heat transfer and increased local overheating side reactions.

[0024] Please see Figure 1-3A reaction vessel for preventing wall adhesion of brominated triazine compounds includes a vessel body 1, which is divided into a cylindrical body and a cylindrical cover. A vertically extending rod 2 passes through the cylindrical cover of the vessel body 1. A horizontal connecting rod 3 is installed at one end of the rod 2 that extends into the vessel body 1. A scraper ring 4 is installed outside the connecting rod 3. The outer edge of the scraper ring 4 is in close contact with the inner circumferential side wall of the vessel body 1, and an ultrasonic transducer 41 is embedded in the scraper ring 4. The other end of the rod 2 extends out of the vessel body 1 and is threadedly connected to a bevel gear ring 8. A bracket 5 is installed on the vessel body 1. The bevel gear ring 8 is horizontally rotatably mounted on the bracket 5. A motor 6 is also fixedly installed on the bracket 5. The output shaft of the motor 6 is connected to a bevel gear 7, and the bevel gear... 7 is perpendicularly engaged with the bevel ring 8. The top side wall of the lifting rod 2 is also equipped with a guide sleeve 10 through the connecting bar 9, and the guide sleeve 10 slides through the guide rod 11. The guide rod 11 is fixedly connected to the cover of the vessel body 1. Specifically, the axis lines of the guide rod 11, the lifting rod 2 and the vessel body 1 are all parallel to each other, and the surface of the guide rod 11 is evenly provided with scale lines along the length direction. The lifting distance can be observed by aligning the guide sleeve 10 with the scale lines. The surface of the connecting rod 3 is embedded with a temperature sensor 31, and the temperature sensor 31 is electrically connected to the control box 25 installed on the vessel body 1. The temperature sensor 31 monitors the reaction temperature in real time and feeds the data back to the controller in the control box 25.

[0025] Please see Figure 2-3 The boom 2 is hollow inside, and the top of the boom 2 is connected to the diaphragm pump 16 through the hose 15, so that the reactants can be extracted through the boom 2 for sampling and inspection. In actual use, the diaphragm pump 16 can be fixed in one place to ensure its stability. It can also pump out excess reaction liquid and stabilize the reaction liquid level.

[0026] Please see Figure 1 and Figure 4 To ensure the airtightness of the vessel body 1, a telescopic sleeve 12 is fitted around the section of the lifting rod 2 extending outside the vessel body 1 to prevent leakage of reactants at the point where the lifting rod 2 penetrates the lid of the vessel body 1. Connecting sleeves 13 are provided at the connection points between the vessel body 1 and the support 5 and the telescopic sleeve 12. The connecting sleeves 13 are threadedly connected to the telescopic sleeve 12, making the installation and connection of the telescopic sleeve 12 convenient. Sealing rings 14 are embedded on the inner walls of both ends of the telescopic sleeve 12, and the sealing rings 14 fit against the ends of the connecting sleeves 13, thereby improving the airtightness of the connection by tightening the sealing rings 14. At the same time, an active sealing system is set up, consisting of a vacuum pump 20, a nitrogen pipe 23, an exhaust gas pipe 21, a pressure compensation valve 22, and a pressure sensor 24. The exhaust gas pipe 21 is connected to an exhaust gas treatment tank, and the nitrogen pipe 23 is connected to a nitrogen storage tank. The vacuum pump 20 and the pressure compensation valve 22 are automatically started and stopped by the control box 25 according to the signal of the pressure sensor 24 to maintain a slight negative pressure inside the vessel and prevent bromine leakage.

[0027] Please see Figure 1The vessel body 1 is also equipped with a bromine dripping pipe 17 and a hydrogen peroxide dripping pipe 18 to facilitate the dripping of bromine and hydrogen peroxide into the vessel body 1 for bromination reaction. The connection between the bromine dripping pipe 17 and the hydrogen peroxide dripping pipe 18 and the vessel body 1 is equipped with a dripping valve 19 to facilitate the adjustment of the dripping flow rate of bromine or hydrogen peroxide.

[0028] Workflow: Start the vacuum pump 20 to extract air, fill the nitrogen pipe 23 with inert gas to replace the air, open the drip valve 19, and add raw materials step by step through the bromine drip pipe 17 and the hydrogen peroxide drip pipe 18. The motor 6 drives the gear set to move the boom 2 up and down along the guide rod 11. The scraper ring 4 scrapes the reactor wall synchronously. The ultrasonic transducer 41 activates the cavitation effect. The temperature sensor 31 monitors the reaction temperature in real time, and the data is fed back to the control box 25 to control the dripping speed of the bromine drip pipe 17. The vacuum pump 20 and the pressure compensation valve 22 are automatically started and stopped by the control box 25 according to the signal of the pressure sensor 24 to maintain a slight negative pressure inside the reactor and prevent bromine leakage. The diaphragm pump 16 draws out excess liquid through the hollow channel of the boom 2.
