Dehydration reactor for solid epoxy resin production

Abstract

This utility model discloses a dehydration kettle for solid epoxy resin production, relating to the technical field of epoxy resin processing equipment. The utility model includes a dehydration kettle equipped with a venting mechanism and a stirring mechanism. By incorporating a venting mechanism, the initial height of the valve plate is adjusted, thereby regulating the pressure released, significantly improving the controllability of pressure release. This prevents excessive pressure during resin dehydration processing, which could lead to explosions or other hazards. Furthermore, when the positioning plate is moved upwards by twisting the threaded rod at the bottom of the handle, it abuts against the bottom of the connecting block, thus closing and fixing the cylinder cover to the feed cylinder. At this time, rotating the connecting pipe causes the air bladder on the connecting pipe to rotate to the top of the cylinder cover. If the air pressure is too high and not released in time, the air pressure will squeeze the air bladder, causing the pressure plate at the bottom of the air bladder to move downwards, preventing steam leakage and potential injury to workers caused by failure to release pressure and open the cylinder cover in time.

Description

Technical Field

[0001] This utility model belongs to the technical field of epoxy resin processing equipment, and in particular relates to a dehydration kettle for the production of solid epoxy resin. Background Technology

[0002] In the complex production process of solid epoxy resin, the dehydration step plays a crucial role, making it one of the key links in the entire production process. This step is so critical because it bears the important mission of removing the moisture contained in the raw materials and the moisture generated during the reaction process. The raw materials inevitably contain a certain amount of moisture, and during the reaction process, additional moisture is generated due to various chemical reactions. If this moisture is not removed, it will have many adverse effects on the quality and performance of the epoxy resin. The primary significance of dehydration is to ensure the purity of the epoxy resin. The presence of moisture introduces impurities, reduces the purity of the epoxy resin, and thus affects its physical and chemical properties. Through effective dehydration treatment, the impurity content can be minimized, ensuring that the epoxy resin reaches a high purity standard, laying a solid foundation for its subsequent applications in various fields.

[0003] In the dehydration process of solid epoxy resin production, when the heating dehydration kettle generates a large amount of steam, causing a sudden increase in internal pressure, it is difficult to effectively and accurately control and release the pressure. In the past, there was a lack of reliable pressure relief methods, and it was impossible to flexibly adjust the pressure relief, which could easily lead to dangerous situations such as explosions when the pressure was too high. Utility Model Content

[0004] The purpose of this invention is to provide a dehydration kettle for the production of solid epoxy resin, which solves the problem by providing the appropriate equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a dehydration kettle for the production of solid epoxy resin, including a dehydration kettle, on which a venting mechanism and a stirring mechanism are provided;

[0007] The venting mechanism includes a feed cylinder connected to the top of the dehydration vessel. A cylinder cover is hinged to the top of the feed cylinder. A venting pipe is connected to the top of the cylinder cover. A threaded rod is threaded to the top of the venting pipe. The bottom end of the threaded rod extends into the interior of the venting pipe. An adjusting plate is fixedly connected to the bottom of the threaded rod. A spring is fixedly connected to the bottom of the adjusting plate. A valve plate is fixedly connected to the bottom of the spring. The valve plate is slidably connected to the interior of the venting pipe. A valve port is provided on the venting pipe. A knob is fixedly connected to the top of the threaded rod.

[0008] Furthermore, an exhaust pipe is connected to the top of the dehydration vessel, and a connecting pipe is rotatably connected to the outer wall of the exhaust pipe.

[0009] Furthermore, an airbag is connected to one end of the connecting pipe away from the exhaust pipe, and a pressure plate is fixedly connected to the bottom of the airbag, with the pressure plate in contact with the top of the cylinder cover.

[0010] Furthermore, a connecting block is fixedly connected to the outer wall of the feed cylinder, a threaded rod 2 is threaded through the cylinder cover, a positioning plate is fixedly connected to the bottom end of the threaded rod 2, the top of the positioning plate contacts the bottom of the connecting block, and a handle is fixedly connected to the top end of the threaded rod 2.

[0011] Furthermore, the stirring mechanism includes a motor fixedly connected to the top of the dehydration vessel, and the output end of the motor is fixedly connected to a rotating rod via a coupling.

[0012] Furthermore, a number of stirring rods are fixedly connected to the outer wall of the rotating rod, and scrapers are fixedly connected to one end of each stirring rod away from the rotating rod. There are three scrapers, and all three scrapers are in contact with the inner wall of the dehydration vessel.

[0013] Furthermore, a discharge cylinder is connected to the bottom of the dehydration kettle, and an electronic valve is installed on the discharge cylinder.

[0014] This utility model has the following beneficial effects:

[0015] 1. By incorporating a venting mechanism, during the dehydration process of solid epoxy resin in a heated dehydration kettle, a large amount of steam is generated, causing a sudden increase in internal pressure. This pressure forces the valve plate upwards. Once the valve plate reaches above the valve opening, the excess pressure is released through the opening, and the spring then rebounds, venting pressure inside the dehydration kettle. The threaded rod, in conjunction with the adjusting plate, adjusts the initial height of the valve plate, thereby regulating the pressure relief. This significantly improves the controllability of pressure relief and prevents excessive pressure during resin dehydration. High pressure can lead to explosions and other hazards. When the positioning plate is moved upward by turning the threaded rod at the bottom of the handle, it will press against the bottom of the connecting block, thus closing and fixing the cylinder cover and the feed cylinder. At this time, rotating the connecting pipe will cause the air bladder on the connecting pipe to rotate to the top of the cylinder cover. If the air pressure is too high and is not released in time, the air pressure will squeeze the air bladder, and the pressure plate at the bottom of the air bladder will move downward, so that the pressure plate presses against the top of the cylinder cover, preventing the cylinder cover from opening. This prevents steam leakage that could cause injury to workers if the cylinder cover is not released in time, and further improves the safety protection of the entire production process.

[0016] 2. By setting up a stirring mechanism, when heating and dehydrating the resin inside the dehydration kettle, the drive motor drives the rotating rod to rotate, thereby causing multiple stirring rods on the rotating rod to stir the resin raw material. At the same time, three rotating scrapers will scrape and wash the inner wall of the dehydration kettle to prevent excessive raw material from adhering to the inner wall of the dehydration kettle, which would lead to uneven heating and improve dehydration efficiency.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a dehydration kettle for solid epoxy resin production, including a dehydration kettle 1, and a venting mechanism 2 and a stirring mechanism 3 are provided on the dehydration kettle 1.

[0028] The venting mechanism 2 includes a feed cylinder 21 connected to the top of the dehydration vessel 1. A cylinder cover 22 is hinged to the top of the feed cylinder 21. A venting pipe 23 is connected to the top of the cylinder cover 22. A threaded rod 24 is threaded to the top of the venting pipe 23. The bottom end of the threaded rod 24 extends into the interior of the venting pipe 23. An adjusting plate 25 is fixedly connected to the bottom of the threaded rod 24. A spring 26 is fixedly connected to the bottom of the adjusting plate 25. A valve plate 27 is fixedly connected to the bottom of the spring 26. The valve plate 27 is slidably connected to the interior of the venting pipe 23. A valve port 2 is provided on the venting pipe 23. 71. A knob 28 is fixedly connected to the top of threaded rod 24. An exhaust pipe 29 is connected to the top of the dewatering vessel 1. A connecting pipe 291 is rotatably connected to the outer wall of the exhaust pipe 29. An air bladder 292 is connected to the end of the connecting pipe 291 away from the exhaust pipe 29. A pressure plate 293 is fixedly connected to the bottom of the air bladder 292. The pressure plate 293 contacts the top of the cylinder cover 22. A connecting block 294 is fixedly connected to the outer wall of the feed cylinder 21. A threaded rod 295 is threaded through the cylinder cover 22. A positioning plate 296 is fixedly connected to the bottom end of the threaded rod 295. The top of the positioning plate 296 contacts the bottom of the connecting block 294. A handle 297 is fixedly connected to the top of the threaded rod 295. Through the provision of a venting mechanism 2, the threaded rod 24 and the adjusting plate 25 cooperate to adjust the initial height of the valve plate 27, thereby adjusting the venting pressure. This greatly improves the controllability of the venting, preventing excessive pressure during resin dehydration and other hazards such as explosions. Furthermore, when the positioning plate 296 moves upward by twisting the threaded rod 295 at the bottom of the handle 297, the positioning plate 296 will abut against... The bottom of the connecting block 294 closes and fixes the cylinder cover 22 and the feed cylinder 21. At this time, the connecting pipe 291 is rotated, so that the air bag 292 on the connecting pipe 291 rotates to the top of the cylinder cover 22. When the air pressure is too high and is not released in time, the air pressure will squeeze the air bag 292. The pressure plate 293 at the bottom of the air bag 292 moves downward, so that the pressure plate 293 abuts against the top of the cylinder cover 22, preventing the cylinder cover 22 from opening. This prevents steam leakage from causing harm to the workers due to the cylinder cover 22 not being released in time, and further improves the safety protection of the entire production process.

[0029] The stirring mechanism 3 includes a motor 31 fixedly connected to the top of the dehydration vessel 1. The output end of the motor 31 is fixedly connected to a rotating rod 32 via a coupling. Several stirring rods 33 are fixedly connected to the outer wall of the rotating rod 32. Scrapers 34 are fixedly connected to the ends of the stirring rods 33 away from the rotating rod 32. There are three scrapers 34, and all three scrapers 34 are in contact with the inner wall of the dehydration vessel 1. A discharge cylinder 35 is connected to the bottom of the dehydration vessel 1. An electronic valve 36 is installed on the discharge cylinder 35. With the stirring mechanism 3, when the resin inside the dehydration vessel 1 is heated and dehydrated, the motor 31 drives the rotating rod 32 to rotate, thereby causing the multiple stirring rods 33 on the rotating rod 32 to stir the resin raw material. At the same time, the three rotating scrapers 34 scrape and wash the inner wall of the dehydration vessel 1 to prevent excessive raw material from adhering to the inner wall of the dehydration vessel 1, which would lead to uneven heating and improve the dehydration efficiency.

[0030] A specific application of this embodiment is as follows: By providing a venting mechanism 2, when solid epoxy resin is dehydrated in the heated dehydration kettle 1, a large amount of steam is generated, causing a sudden increase in the gas pressure inside the dehydration kettle 1. This pressure compresses and pushes the valve plate 27 upward. When the valve plate 27 moves above the valve port 271, the excess gas pressure is discharged from the valve port 271 and then rebounds via the spring 26, thereby venting the pressure inside the dehydration kettle 1. The threaded rod 24 and the adjusting plate 25 cooperate to adjust the initial height of the valve plate 27, thereby adjusting the pressure relief, greatly improving the controllability of pressure relief, and preventing excessive pressure during resin dehydration from causing explosions or other hazards. In addition, when the positioning plate 296 is moved upward by rotating the threaded rod 295 at the bottom of the handle 297, the positioning plate 296 will abut against the bottom of the connecting block 294, thereby closing and fixing the cylinder cover 22 and the feed cylinder 21. At this time, rotating the connecting pipe 291 will cause the air bag 292 on the connecting pipe 291 to rotate to the top of the cylinder cover 22. If the air pressure is too high and is not released in time, the air pressure will squeeze the air bag 292, and the pressure plate 293 at the bottom of the air bag 292 will move downward, so that the pressure plate 293 abuts against the top of the cylinder cover 22, preventing the cylinder cover 22 from opening. This prevents the cylinder cover 22 from being opened in time without releasing pressure, which could lead to steam leakage and cause injury to the workers, and further improves the safety protection of the entire production process.

[0031] With the stirring mechanism 3 installed, when the resin inside the dehydration kettle 1 is heated and dehydrated, the drive motor 31 drives the rotating rod 32 to rotate, thereby causing multiple stirring rods 33 on the rotating rod 32 to stir the resin raw material. At the same time, three rotating scrapers 34 will scrape and wash the inner wall of the dehydration kettle 1 to prevent excessive raw material adhering to the inner wall of the dehydration kettle 1, which would lead to uneven heating and improve dehydration efficiency.
