Description

Technical Field

[0001] This utility model belongs to the field of distillation kettle technology, and in particular relates to a high-efficiency distillation kettle. Background Technology

[0002] Distillation kettles are devices used in the chemical and pharmaceutical industries to separate liquid mixtures. They purify components by heating, vaporizing, condensing, and refluxing the liquid mixture. They mainly utilize the different volatility of different liquids to separate the components, thereby extracting the desired liquid from the liquid mixture while ensuring the concentration of the extracted liquid.

[0003] During the use of a distillation vessel, the steam generated inside enters the cooling device. However, traditional cooling devices often use spiral pipes for condensation, resulting in less contact between the steam and the cooling device, which affects the condensation efficiency and the production efficiency of the distillation vessel. To solve these problems, there is an urgent need for a high-efficiency distillation vessel. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency distillation vessel to solve the problem of low condensation efficiency caused by the limited contact area between the condensing device and the steam.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency distillation vessel, comprising a distillation vessel, wherein a conveying pipe is provided at the top of the distillation vessel; The cooling assembly includes a housing with an opening at the top of the housing facing one end of the delivery pipe; and a cooling pipe with a straight outer wall and a spherical structure on the outer wall, and a spiral tube on the outer wall, with both ends of the spiral tube connected to the cooling pipe. A sealing assembly, wherein the sealing assembly is located between the housing and the delivery pipe; During distillation, the steam in the distillation vessel enters the outer shell through the delivery pipe and the opening at the top of the outer shell, allowing the steam to come into full contact with the cooling pipe and spiral tube. At the same time, cooling water is introduced into the cooling pipe and spiral tube to cool and condense the steam.

[0006] As a further description of the above technical solution: It also includes: a buffer tank, which is a box with an opening at the top. The top of the buffer tank is fixedly connected to the opening at the bottom of the outer shell. The bottom of the buffer tank is provided with a reflux pipe and a discharge pipe, and the other end of the reflux pipe is connected to the distillation kettle.

[0007] As a further description of the above technical solution: It also includes: an electric push rod, one end of which is fixedly connected to the buffer box, and the telescopic end of the electric push rod extends into the buffer box through an opening on one side of the buffer box, and the telescopic end of the electric push rod is provided with a partition.

[0008] As a further description of the above technical solution: The partition is located inside the buffer tank and provides some protection to the inlet of the return pipe.

[0009] As a further description of the above technical solution: It also includes: the sealing component includes a connecting pipe, the connecting pipe is direct, and one end of the connecting pipe is connected to the opening on the top of the outer shell, and the other end of the connecting pipe is connected to the delivery pipe.

[0010] As a further description of the above technical solution: It also includes: a fixing frame, which has multiple fan-shaped openings inside, an installation cylinder installed on one side of the fixing frame, and the outer wall of the fixing frame being fixedly connected to the inner wall of the connecting pipe.

[0011] As a further description of the above technical solution: It also includes: a sealing frame, which is arranged opposite to the fixed frame, and the surface of the sealing frame is provided with a blocking block corresponding to the fan-shaped opening in the fixed frame, and a sliding rod is installed on one side of the sealing frame.

[0012] As a further description of the above technical solution: The slide rod is slidably connected to the mounting cylinder through a groove inside the mounting cylinder, and a sealing structure is provided between the slide rod and the mounting cylinder. A spring is provided on the outer wall of the slide rod. When steam is sent into the outer shell through the delivery pipe, when the gas pressure inside the distillation vessel reaches a certain level, the sealing frame is pushed by the gas pressure and separates from the fixed frame, allowing the steam to pass through the fan-shaped openings in the fixed frame and the sealing frame and enter the outer shell.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, when condensing the steam discharged from the distillation vessel, the spiral tube is equipped with a cooling tube, and the outer wall of the cooling tube has a spherical structure. This allows the steam entering the spiral tube to be rapidly cooled by the cooling tube, thereby improving the cooling efficiency of the spiral tube and reducing the impact on the efficiency of the distillation vessel. At the same time, the degree of obstruction at the liquid inlet of the reflux tube can be adjusted by the baffle, thereby regulating the flow rate of the reflux liquid. In this way, the efficient operation of the distillation vessel can be ensured by controlling the reflux flow rate.

[0014] In this invention, when the distillation vessel is first heated, the opening of the fixed frame can be sealed by the sealing frame, so that the inside of the distillation vessel is in a certain sealed state, thereby improving the efficiency of the liquid heating and evaporation inside the distillation vessel. When the gas pressure inside the distillation vessel reaches a certain level, the gas pressure can separate the sealing frame and the fixed frame, so that the steam passes through the fan-shaped opening of the sealing frame and the fixed frame and enters the outer shell for cooling.

[0020] 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.

[0021] In its specific implementation, such as Figures 1-5 This utility model provides a technical solution: a high-efficiency distillation kettle, including a distillation kettle 1, with a conveying pipe 2 at the top of the distillation kettle 1; Cooling assembly 4 includes a housing 403, with an opening at the top of the housing 403 facing one end of the conveying pipe 2; cooling pipe 401, which has a straight outer wall and a spherical structure on the outer wall; a spiral pipe 402 on the outer wall of the cooling pipe 401, with both ends of the spiral pipe 402 connected to the cooling pipe 401. The sealing component 3 is located between the housing 403 and the delivery pipe 2; During distillation, the steam in the distillation vessel 1 enters the outer shell 403 through the delivery pipe 2 and the opening at the top of the outer shell 403, allowing the steam to fully contact the cooling pipe 401 and the spiral pipe 402. Simultaneously, cooling water is introduced into the cooling pipe 401 and the spiral pipe 402 to cool and condense the steam. The system also includes a buffer tank 406, which is a box with an opening at the top. The top of the buffer tank 406 is fixedly connected to the opening at the bottom of the outer shell 403. The bottom of the buffer tank 406 has... The system includes a reflux pipe 407 and a discharge pipe 408, with the other end of the reflux pipe 407 connected to the distillation vessel 1. It also includes an electric push rod 404, one end of which is fixedly connected to a buffer tank 406. The telescopic end of the electric push rod 404 extends into the buffer tank 406 through an opening on one side of the buffer tank 406. The telescopic end of the electric push rod 404 is provided with a partition 405, which is located inside the buffer tank 406 and provides some obstruction to the inlet of the reflux pipe 407.

[0022] Specifically, when the distillation vessel 1 is in operation, the internal steam enters the outer shell 403 through the conveying pipe 2 and the connecting pipe 306. At the same time, coolant is introduced into the cooling pipe 401 and the spiral pipe 402. The steam is condensed due to the low temperature of the cooling pipe 401 and the spiral pipe 402. Since the outer wall of the cooling pipe 401 has a spherical structure and the cooling pipe 401 is located inside the spiral of the spiral pipe 402, the steam inside the spiral of the spiral pipe 402 can be condensed quickly, thereby improving the condensation efficiency. The liquid produced by condensation gradually flows into the buffer tank 406 and is discharged from the discharge pipe 408 and the return pipe 407. At the same time, the electric push rod 404 can drive the baffle 405 to block the return pipe 407 to a certain extent, thereby adjusting the flow rate of liquid flowing back into the distillation vessel 1 from the return pipe 407. like Figure 5As shown, the sealing assembly 3 includes a connecting pipe 306, which is a direct connection. One end of the connecting pipe 306 is connected to an opening on the top of the outer casing 403, and the other end is connected to the delivery pipe 2. It also includes a fixing frame 302, which has multiple fan-shaped openings. An installation cylinder 301 is installed on one side of the fixing frame 302. The outer wall of the fixing frame 302 is fixedly connected to the inner wall of the connecting pipe 306. It also includes a sealing frame 305, which is arranged opposite to the fixing frame 302. The surface of the sealing frame 305 is provided with blocking blocks corresponding to the fan-shaped openings in the fixing frame 302. A sliding rod 303 is installed on one side of the sealing frame 305. The sliding rod 303 is slidably connected to the installation cylinder 301 through a groove in the installation cylinder 301. A sealing structure is provided between the sliding rod 303 and the installation cylinder 301. A spring 304 is provided on the outer wall of the sliding rod 303. When steam is sent into the outer shell 403 through the conveying pipe 2, when the gas pressure in the distillation vessel 1 reaches a certain level, the sealing frame 305 is pushed by the gas pressure and separates from the fixed frame 302, so that the steam passes through the fan-shaped openings opened in the fixed frame 302 and the sealing frame 305 and enters the outer shell 403. Specifically, when the distillation vessel 1 is first put into use, the temperature and pressure inside the distillation vessel 1 are low, so the internal pressure is insufficient to push the sealing frame 305 and the fixed frame 302 to separate. This keeps the inside of the distillation vessel 1 sealed, allowing it to heat up and evaporate quickly. When the internal pressure can push the sealing frame 305 and the fixed frame 302 to separate, causing the spring 304 to compress, the steam can pass through the fan-shaped openings in the sealing frame 305 and the fixed frame 302 and enter the outer shell 403.

[0023] Working principle: When the distillation vessel 1 is first put into use, the internal temperature and pressure are low, and the internal pressure is insufficient to push the sealing frame 305 and the fixed frame 302 apart. The sealed device inside the distillation vessel 1 allows for rapid heating and evaporation. When the internal pressure is sufficient to push the sealing frame 305 and the fixed frame 302 apart, causing the spring 304 to compress, the steam can pass through the fan-shaped openings in the sealing frame 305 and the fixed frame 302 into the outer shell 403, and then flow into the cooling pipe 401 and the spiral pipe 4. Coolant is introduced into the 02 section. The low temperature of the cooling pipe 401 and the spiral pipe 402 causes the steam to condense. Since the outer wall of the cooling pipe 401 has a spherical structure and the cooling pipe 401 is located inside the spiral pipe 402, the steam inside the spiral pipe 402 can be quickly condensed, improving the condensation efficiency. The liquid produced by condensation gradually flows into the buffer tank 406 and is discharged from the discharge pipe 408 and the return pipe 407. The return pipe 407 can be blocked to a certain extent by the baffle 405 driven by the electric push rod 404.
