Description

Technical Field

[0001] This utility model relates to the field of cyanate processing technology, and in particular to a distillation device for processing special isocyanates. Background Technology

[0002] Cyanate esters are a class of compounds containing cyanate groups, widely used in industry. They possess excellent heat resistance, mechanical properties, and dielectric properties, and are often used to manufacture high-performance materials. For example, in the field of composite materials, cyanate ester resins are important raw materials, enabling the production of lightweight, high-strength components for use in aerospace, electronics, and other industries, enhancing the high-temperature resistance and corrosion resistance of products.

[0003] In the existing technology, when processing cyanate esters, a fixed gas pressure is usually used for distillation in the barrel. Although this method can maintain basic distillation conditions and separate impurities by means of gas-liquid mass transfer, it is difficult to flexibly adjust the boiling point difference of each component when faced with fluctuations in the composition of the feed, which may affect the separation efficiency. At the same time, for sensitive materials such as cyanate esters, a fixed gas pressure is difficult to deal with sudden situations, which may increase the risk of decomposition or polymerization. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a distillation device for processing special isocyanates.

[0005] This utility model is achieved by the following technical solution: a distillation device for processing special isocyanates, including a distillation tank, a pressure regulating component inside the distillation tank, a locking component inside the distillation tank, and a mixing component inside the distillation tank;

[0006] The pressure regulating assembly includes a support plate fixedly connected to the top of the distillation tank. A motor is fixedly connected to the bottom of the support plate, and a threaded rod is fixedly connected to the output end of the motor. A limit block is fixedly connected to the end of the threaded rod away from the motor. A rotating column is slidably connected to the outer wall of the limit block, and a sealing plate is rotatably connected to the outer wall of the rotating column. A spring telescopic rod is fixedly connected to the bottom of the sealing plate. A half-nut is threadedly connected to the threaded rod, and a cylinder is fixedly connected to the outer wall of the half-nut. A support frame is fixedly connected to the bottom of the cylinder, and a guide rod is slidably connected inside the support frame.

[0007] As a further improvement to the above solution, the spring telescopic rod is fixedly connected to the bottom of the inner wall of the distillation tank, the support frame is fixedly connected to the top of the sealing plate, and the guide rod is fixedly connected to the outer wall of the half nut.

[0008] Through the above technical solution, the raw material enters the distillation tank through the feed pipe. At this time, the support plate supports the motor, which drives the threaded rod to rotate. The threaded rod drives the rotating column to rotate through the limiting block, so that the rotating column rotates inside the sealing plate. When it is necessary to adjust the gas pressure inside the distillation tank, the cylinder operates to push the half nut. The guide rod slides inside the support frame while being fixed to the half nut, thereby guiding the half nut to accurately engage with the threaded rod. At this time, the sealing plate drives the rotating column to move, so that the rotating column slides along the outer wall of the limiting block. This compresses the gas pressure inside the distillation tank, thereby flexibly adjusting the boiling point, improving the separation efficiency of the raw material, and reducing the risk of cyanate decomposition or polymerization.

[0009] As a further improvement to the above solution, the locking component includes a fixing block, which is fixedly connected to the inner wall of the distillation tank. A locking groove is provided inside the fixing block. A support plate is fixedly connected to the top of the half nut, and a locking rod is fixedly connected to the outer wall of the support plate.

[0010] As a further improvement to the above solution, the mixing component includes a stirring rod, which is fixedly connected to the bottom of the threaded rod and to the outer wall of the limiting block. A fixing column is slidably connected to the outer wall of the stirring rod.

[0011] As a further improvement to the above solution, a connecting plate is fixedly connected to the outer wall of the fixed column, and an auxiliary stirring rod is rotatably connected to the end of the connecting plate away from the fixed column.

[0012] As a further improvement to the above solution, a gear is fixedly connected to the outer wall of the auxiliary stirring rod, the gear meshes with a toothed ring, and the toothed ring is fixedly connected to the bottom of the sealing plate.

[0013] Through the above technical solution, the threaded rod is fixed to the stirring rod, which in turn is fixed to the limiting block. A fixed column slides on the outer wall of the limiting block, and the fixed column causes the auxiliary stirring rod to rotate inside the connecting plate through the connecting plate. At the same time, the gear meshes with the gear ring, thereby causing the auxiliary stirring rod to rotate. The gear ring is fixed to the bottom of the sealing plate. Through the stirring rod and the auxiliary stirring rod, the raw materials inside the distillation tank are fully mixed, reducing the difference in the residence time of materials in the tank, reducing the risk of some materials deteriorating due to prolonged residence, thereby improving the overall production efficiency, increasing the distillation efficiency and product purity.

[0014] As a further improvement to the above solution, a feed pipe is connected inside the distillation tank, an exhaust pipe is connected inside the distillation tank, and a discharge pipe is connected inside the distillation tank on the side near the exhaust pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention involves feeding raw materials into a distillation tank through a feed pipe. A support plate supports a motor, which drives a threaded rod to rotate. The threaded rod, via a limiting block, drives a rotating column to rotate inside a sealing plate. When pressure adjustment is needed inside the distillation tank, a cylinder pushes a half-nut. A guide rod, fixed to the half-nut, slides inside the support frame, guiding the half-nut to accurately engage with the threaded rod. The sealing plate then moves the rotating column, causing it to slide along the outer wall of the limiting block. This compresses the pressure inside the distillation tank, allowing for flexible adjustment of the boiling point, improving raw material separation efficiency, and reducing the risk of cyanate decomposition or polymerization.

[0017] This invention uses a threaded rod fixed to a stirring rod, which in turn is fixed to a limiting block. A sliding fixed column is located on the outer wall of the limiting block. The fixed column, through a connecting plate, causes the auxiliary stirring rod to rotate inside the connecting plate. Simultaneously, a gear meshes with a gear ring, causing the auxiliary stirring rod to rotate. The gear ring is fixed to the bottom of the sealing plate. Through the stirring rod and the auxiliary stirring rod, the raw materials inside the distillation tank are thoroughly mixed, reducing the difference in the residence time of materials in the tank and lowering the risk of some materials deteriorating due to prolonged residence. This improves overall production efficiency, distillation efficiency, and product purity. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-6 This embodiment provides a distillation apparatus for processing special isocyanates, including a distillation tank 1, a pressure regulating component 2, a locking component 3, and a mixing component 4.

[0029] The pressure regulating component 2 includes a support plate 201, which is fixedly connected to the top of the distillation tank 1. A motor 202 is fixedly connected to the bottom of the support plate 201. A threaded rod 203 is fixedly connected to the output end of the motor 202. A limit block 204 is fixedly connected to the end of the threaded rod 203 away from the motor 202. A rotating column 205 is slidably connected to the outer wall of the limit block 204. A sealing plate 206 is rotatably connected to the outer wall of the rotating column 205. A spring telescopic rod 207 is fixedly connected to the bottom of the sealing plate 206. A half nut 208 is threadedly connected to the threaded rod 203. A cylinder 209 is fixedly connected to the outer wall of the half nut 208. A support frame 210 is fixedly connected to the bottom of the cylinder 209. A guide rod 211 is slidably connected inside the support frame 210.

[0030] The spring telescopic rod 207 is fixedly connected to the bottom of the inner wall of the distillation tank 1, the support frame 210 is fixedly connected to the top of the sealing plate 206, and the guide rod 211 is fixedly connected to the outer wall of the half nut 208.

[0031] The locking component 3 includes a fixing block 301, which is fixedly connected to the inner wall of the distillation tank 1. A locking groove 302 is provided inside the fixing block 301. A support plate 303 is fixedly connected to the top of the half nut 208. A locking rod 304 is fixedly connected to the outer wall of the support plate 303.

[0032] The mixing component 4 includes a stirring rod 401, which is fixedly connected to the bottom of the threaded rod 203 and to the outer wall of the limiting block 204. A fixing column 402 is slidably connected to the outer wall of the stirring rod 401.

[0033] A connecting plate 403 is fixedly connected to the outer wall of the fixed column 402, and an auxiliary stirring rod 404 is rotatably connected to the end of the connecting plate 403 away from the fixed column 402.

[0034] A gear 405 is fixedly connected to the outer wall of the auxiliary stirring rod 404. The gear 405 is meshed with a toothed ring 406, which is fixedly connected to the bottom of the sealing plate 206.

[0035] A feed pipe 5 is connected inside the distillation tank 1, an exhaust pipe 6 is connected inside the distillation tank 1, and a discharge pipe 7 is connected inside the distillation tank 1 on the side near the exhaust pipe 6.

[0036] The implementation principle of a special isocyanate processing distillation device in this embodiment is as follows: Raw material enters the distillation tank 1 through the feed pipe 5. At this time, the support plate 201 supports the motor 202, which drives the threaded rod 203 to rotate. The threaded rod 203, through the limiting block 204, drives the rotating column 205 to rotate, causing the rotating column 205 to rotate inside the sealing plate 206. When it is necessary to adjust the gas pressure inside the distillation tank 1, the cylinder 209 operates to push the half-nut 208. The guide rod 211, while fixed to the half-nut 208, slides inside the support frame 210, from... The half-nut 208 is guided to accurately engage with the threaded rod 203. At this time, the sealing plate 206 drives the rotating column 205 to slide along the outer wall of the limiting block 204, compressing the gas pressure inside the distillation tank 1. This allows for flexible adjustment of the boiling point, improving the separation efficiency of the raw materials and reducing the risk of cyanate decomposition or polymerization. Once the specified gas pressure is reached, the cylinder 209 drives the half-nut 208 to retract rapidly, disengaging it from the threaded rod 203. Simultaneously, a spring telescopic rod 207 is fixed to the bottom of the sealing plate 206. 207 provides temporary support to the sealing plate 206. At this time, the half nut 208 drives the locking rod 304 to move through the support plate 303. When the limiting block 204 slides on the outer wall of the locking groove 302, the fixing block 301 has several locking grooves 302, which fixes the sealing plate 206 as a whole. At the same time, the threaded rod 203 is fixed to the stirring rod 401, and the stirring rod 401 is fixed to the limiting block 204. The fixing post 402 slides on the outer wall of the limiting block 204. The fixing post 402 causes the auxiliary stirring rod 404 to rotate inside the connecting plate 403 through the connecting plate 403. At the same time, the gear 405 and the gear... The ring 406 engages, causing the auxiliary stirring rod 404 to rotate. The toothed ring 406 is fixed to the bottom of the sealing plate 206. Since the toothed ring 406 is convex, the gear 405 will not disengage from the toothed ring 406. Through the stirring rod 401 and the auxiliary stirring rod 404, the raw materials inside the distillation tank 1 are fully mixed, reducing the difference in the residence time of the materials in the tank and reducing the risk of some materials deteriorating due to long residence time. This improves the overall production efficiency, distillation efficiency and product purity. When the position of the sealing plate 206 is adjusted, the fixing column 402 also slides with the limiting block 204.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
