Description

Technical Field

[0001] This utility model generally relates to the field of separation and purification technology, and more specifically, to a separation system. Background Technology

[0002] 1,5-Pentanediamine (DN5, abbreviated as pentanediamine), also known as cadaverine, has wide applications in agriculture, medicine, and industry. 1,5-Pentanediamine can be prepared through biotransformation, specifically fermentation or enzymatic conversion. The solid-liquid mixture produced during the extraction of 1,5-pentanediamine from the fermentation broth or enzymatic conversion solution contains sugars, proteins, metabolic byproducts, and inorganic salt impurities from the biotransformation process. The solid content of this mixture is typically 10%–80%, and it also contains water and a small amount of pentanediamine. Pentanediamine is a liquid at room temperature. If evaporation or distillation is used to extract the 1,5-pentanediamine product from this solid-liquid mixture, the viscosity of the system increases in the later stages of evaporation or distillation, reducing distillation efficiency and increasing energy consumption. Furthermore, the currently used intermittent evaporation or distillation methods generally cannot achieve continuous production. Evaporation of 1,5-pentanediamine has low production efficiency and results in energy waste and high production costs. At the same time, the instability of product quality will also have an adverse effect, failing to meet the quality requirements of 1,5-pentanediamine products. Utility Model Content

[0070] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0071] This embodiment provides a separation system, such as Figure 1 As shown, the separation system includes an adjusting tank 1, a drying mechanism 2, and a condensing mechanism 3. The adjusting tank 1 is used to contain the raw materials to be separated. The drying mechanism 2 includes a drying tank 21 and a drying assembly 22. The drying tank 21 is connected to the adjusting tank 1. The drying assembly 22 is at least partially disposed within the drying tank 21 and is rotatable relative to the drying tank 21. It is used to stir the raw materials to be separated within the drying tank 21 and to heat the raw materials to be separated, causing them to form solid residue and vapor. The condensing mechanism 3 is connected to the drying tank 21 and is used to liquefy the vapor to form a liquid.

[0072] The raw material to be separated is specifically a feed solution containing 1,5-pentanediamine. The adjusting tank 1 is equipped with an inlet 101, through which the raw material to be separated can be directly added. Alternatively, various raw materials for preparing the feed solution containing 1,5-pentanediamine can be added to the inlet 101, and then reacted in the adjusting tank 1 to obtain the raw material to be separated. The feed solution containing 1,5-pentanediamine can be prepared, for example, by a solution system containing 1,5-pentanediamine salt and an alkaline substance. The two react to form a solution system containing free 1,5-pentanediamine, i.e., a feed solution containing 1,5-pentanediamine.

[0073] For example, the feed inlet 101 includes a first feed inlet 1011 and a second feed inlet 102. The first feed inlet 1011 is used to introduce a solution system containing 1,5-pentanediamine salt. For example, the solution system containing 1,5-pentanediamine salt includes fermentation broth or enzyme conversion broth containing 1,5-pentanediamine salt. The second feed inlet 102 is used to introduce an alkaline substance. For example, the alkaline substance may include, but is not limited to, alkali metal oxides / hydroxides, alkaline earth metal oxides / hydroxides, and corresponding alkaline salts. The alkaline salt includes at least one of sodium phosphate, potassium phosphate, sodium carbonate, and potassium carbonate.

[0074] Specifically, if the solution system containing 1,5-pentanediamine salt is an enzyme conversion solution of 1,5-pentanediamine salt, it can be obtained by reacting a lysine salt solution with lysine decarboxylase (LDC). The lysine salt can be an inorganic or organic salt of lysine, such as commercially available lysine salts or lysine sulfates.

[0075] Specifically, if the solution system containing 1,5-pentanediamine salt is a fermentation broth containing 1,5-pentanediamine salt, when the fermentation broth containing 1,5-pentanediamine salt needs to be produced, the expression of lysine decarboxylase can be upregulated in a strain capable of producing lysine using gene technology, or lysine decarboxylase can be recombinantly expressed. This allows the lysine produced during fermentation to be simultaneously converted into pentanediamine, thereby directly obtaining a fermentation broth containing 1,5-pentanediamine salt. This embodiment does not have special requirements for the recombinant strain, as long as 1,5-pentanediamine can be obtained.

[0076] It is understood that this embodiment does not particularly limit the specific preparation method of 1,5-pentanediamine by enzyme conversion solution containing 1,5-pentanediamine salt or by direct fermentation. The specific raw materials can be selected according to actual production needs, and the specific process parameters of the enzyme conversion process can be determined to obtain an aqueous solution containing 1,5-pentanediamine salt.

[0077] The solid content (solid content) of the feed liquid containing 1,5-pentanediamine is 10% to 80%, further 20% to 70%, further 40% to 60%, for example, 30%, 40%, 50%, etc.

[0078] The feed liquid containing 1,5-pentanediamine includes 1,5-pentanediamine and water, and the content (moisture content) of 1,5-pentanediamine and water is 20% to 90%, further 30% to 80%, further 40% to 60%, for example, 40%, 50%, 60%, etc.

[0079] The 1,5-pentanediamine content in the feed solution is 8% to 75%, for example, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, etc.

[0080] For example, the shape of the adjusting tank 1 can be a cylindrical structure, a cuboid structure, etc. Along the axial direction of the adjusting tank 1, the feed inlet 101 can be provided at the top of the adjusting tank 1, and the discharge outlet 102 is provided at the bottom of the adjusting tank 1. The discharge outlet 102 is used to output the raw material to be separated to the drying tank 21 of the drying mechanism 2.

[0081] For example, the drying component 22 of the drying unit 2 can stir the raw materials to be separated, thereby improving the mixing uniformity of the raw materials. The heating method of the drying component 22 can be selected from at least one of metal plate heating, steam heating, heat transfer oil heating, and electric heating. Under the heating action of the drying component 22, the raw materials to be separated, which are in a liquid state, can be evaporated to form solid residue in a solid state and vapor in a gaseous state. Specifically, the vapor contains 1,5-pentanediamine, for example, the vapor specifically includes 1,5-pentanediamine gas and water vapor.

[0082] For example, the condensing mechanism 3 may be a heat exchanger. Steam output from the drying mechanism 2 enters the condensing mechanism 3. The high-temperature steam is cooled and liquefied in the condensing mechanism 3 to form a liquid, so as to obtain a finished product containing 1,5-pentanediamine.

[0083] The separation system provided in this embodiment, after the raw material to be separated in the adjusting tank 1 is transported to the drying tank 21, the drying component 22 can stir and heat the raw material to achieve a solid-gas separation process, forming solid residue and steam. The solid residue is deposited in the drying tank 21, and the steam enters the condensation mechanism 3 and liquefies to form a liquid. This separation system has a high degree of automation, a high material handling capacity, and can obtain high-purity 1,5-pentanediamine products, achieving continuous separation of 1,5-pentanediamine.

[0084] Meanwhile, the drying component 22 can stir the raw materials to be separated, improving the mixing uniformity of the raw materials and also dispersing them to a certain extent, thereby increasing the contact area between the raw materials and the drying component 22, resulting in faster drying speed and improved drying efficiency. Furthermore, the direct contact between the drying component 22 and the raw materials ensures high thermal energy utilization efficiency and reduces production costs.

[0085] In one embodiment, the separation system further includes a stirring assembly (not shown in the figure), which is at least partially rotatably disposed in the adjustment tank 1. The stirring assembly is used to stir the raw materials to be separated in order to ensure the uniformity of the mixing of the raw materials to be separated.

[0086] For example, the stirring assembly includes a stirring drive source and a stirring paddle. The stirring drive source may be a rotary motor. The stirring drive source is located outside the adjustment tank 1, and the stirring paddle is located inside the adjustment tank 1. The output end of the stirring drive source is connected to the stirring paddle. The stirring drive source can drive the stirring paddle to rotate relative to the adjustment tank 1 to achieve the purpose of mixing the raw materials to be separated.

[0087] In one embodiment, the separation system further includes a temperature control component (not shown in the figure). Exemplarily, the temperature control component is at least one of metal plate heating, steam heating, heat transfer oil heating, and electric heating. The temperature control component is disposed in the adjustment tank 1 and is used to preheat the raw material to be separated so that the raw material to be separated has a certain temperature before entering the drying mechanism 2, which is beneficial to the drying efficiency of the raw material to be separated in the drying mechanism 2.

[0088] In one embodiment, the separation system further includes a feed pump 6, which is disposed between the adjustment tank 1 and the material distribution mechanism 4. The feed pump 6 is used to transport the raw material to be separated in the adjustment tank 1 to the material distribution mechanism 4, and the feed pump 6 provides conveying power for the conveying of the raw material to be separated.

[0089] Specifically, the separation system includes a first infusion pipe 9 and a second infusion pipe 10. One end of the first infusion pipe 9 is connected to the outlet 102 of the adjusting tank 1, and the other end is connected to the inlet of the feed pump 6. One end of the second infusion pipe 10 is connected to the outlet of the feed pump 6, and the other end is connected to the material distribution mechanism 4. Under the driving action of the feed pump 6, the raw material to be separated in the adjusting tank 1 is transported to the material distribution mechanism 4 through the first infusion pipe 9 and the second infusion pipe 10.

[0090] In one embodiment, such as Figure 1 As shown, the separation system also includes a filter 7, which is disposed between the adjustment tank 1 and the cloth feeding mechanism 4. The filter 7 is used to filter the raw material to be separated in the adjustment tank 1 to remove impurities and improve the cleanliness of the raw material to be separated.

[0091] For example, the filter 7 can be installed in the second infusion pipe 10 or the first infusion pipe 9, so that the raw material to be separated is filtered before entering the feed pump 6, thus preventing impurities in the raw material to be separated from entering the feed pump 6 and causing blockage of the feed pump 6.

[0092] In one embodiment, such as Figure 1 As shown, the separation system also includes a feeding mechanism 4, which is connected to the adjusting tank 1 and located inside the drying tank 21. The feeding mechanism 4 is used to convey the raw material to be separated to the drying assembly 22.

[0093] For example, the outlet 102 of the adjusting tank 1 is connected to the material distribution mechanism 4 through the first liquid delivery pipe 9 and the second liquid delivery pipe 10, so that the raw material to be separated output from the adjusting tank 1 is distributed into the drying mechanism 2 through the material distribution mechanism 4 after passing through the first liquid delivery pipe 9 and the second liquid delivery pipe 10. For example, the material distribution mechanism 4 can be a material distribution pipe or a material distribution nozzle, and the material distribution mechanism 4 can distribute the raw material to be separated in the form of small droplets, thin layers, etc., into the drying tank 21 or onto the drying component 22.

[0094] In another embodiment, the separation system further includes a separation mechanism (not shown in the figure), which is disposed between the drying mechanism 2 and the condensing mechanism 3 and is connected to the drying mechanism 2 and the condensing mechanism 3 respectively, so that the steam discharged from the drying mechanism 2 is separated into solid and gas and then enters the condensing mechanism 3.

[0095] Since the steam discharged from the first outlet 212 of the drying tank 21 contains not only 1,5-pentanediamine but also carries a small amount of residue, the steam enters the separation mechanism for secondary solid-gas separation, thereby increasing the purity of the steam entering the condensation mechanism 3 and improving the separation quality.

[0096] In one embodiment, such as Figure 1 As shown, the separation system also includes a vacuum component 5. Exemplarily, the vacuum component 5 may be a vacuum pump. The vacuum component 5 is connected to the condensation mechanism 3 and is used to extract air from the drying mechanism 2 through the condensation mechanism 3.

[0097] A vacuum environment is created inside the drying tank 21 by using vacuum component 5 to create a vacuum. This negative pressure environment helps lower the boiling point of the liquid, making 1,5-pentanediamine more easily vaporized at a lower temperature and reducing energy waste in the drying unit 2. For example, 1,5-pentanediamine has a high boiling point at atmospheric pressure, but its boiling point is significantly lowered under vacuum conditions, allowing for more efficient conversion from liquid to gas.

[0098] Meanwhile, because the vacuum environment reduces the obstruction of the surrounding gas to the droplets, the molecules on the surface of the droplets can escape more easily, that is, the atomized droplets can evaporate faster, thereby accelerating the vaporization process of 1,5-pentanediamine, improving drying efficiency, and reducing the energy consumption of the drying mechanism 2.

[0099] Furthermore, the function of the vacuum component 5 is not limited to the interior of the drying tank 21, but extends to the subsequent separation mechanism. Vapor containing 1,5-pentanediamine is extracted from the drying tank 21 under vacuum conditions and enters the separation mechanism. The vacuum environment helps reduce the amount of impurities and residues carried in the vapor, facilitating more efficient separation of pure 1,5-pentanediamine vapor, improving separation efficiency, and thus increasing the purity of the final product.

[0100] In another embodiment, the separation system further includes a vacuum component 5, which is in communication with the drying mechanism 2 and is used to extract air from the drying mechanism 2.

[0101] In this way, the vacuum component 5 can directly extract air from the drying tank 21 of the drying mechanism 2, reduce the pressure inside the drying tank 21, promote the rapid evaporation of atomized droplets, improve separation efficiency, and thus significantly improve the efficiency of the entire production process and product quality.

[0102] In one embodiment, such as Figure 1 As shown, the separation system also includes a purification mechanism 8, which includes at least one of a distillation unit, a distillation unit, and an evaporation unit. Exemplarily, the purification mechanism 8 may be a distillation column. The purification mechanism 8 is connected to a condensation unit 3, so that the vapor containing 1,5-pentanediamine is condensed into a liquid by the condensation unit 3, and the liquid is then passed into the purification mechanism 8 for distillation treatment. The purification mechanism 8 is used to purify the liquid to obtain the 1,5-pentanediamine product.

[0103] Specifically, such as Figures 1-2 As shown, the shape of the drying tank 21 can be a regular or irregular structure such as a cylinder, cuboid, or cone. In this embodiment, the drying tank 21 is cylindrical. The inner wall and / or outer wall of the drying tank 21 are provided with a heat insulation layer, which serves to keep the heat inside the drying tank 21 from being lost.

[0104] Along the axial direction of the drying tank 21, the top of the drying tank 21 is provided with a liquid inlet 211, which is connected to the adjusting tank 1. For example, the cloth feeding mechanism 4 passes through the liquid inlet 211 and sprays the raw material to be separated toward the drying assembly 22.

[0105] The top of the drying tank 21 is also provided with an air outlet 212, which is connected to the condensing mechanism 3. The steam in the drying tank 21 can be collected in the upper part of the drying tank 21, and can be discharged through the air outlet 212 at the top and transported to the condensing mechanism 3.

[0106] The bottom of the drying tank 21 is provided with a discharge conveyor 213. Since the solid residue has a relatively large mass, the solid residue can settle in the lower half of the drying tank 21, which is conducive to being discharged through the discharge conveyor 213.

[0107] In another embodiment, the separation system further includes a conveying mechanism (not shown) connected to a discharge conveyor 213, through which solid residue discharged from the discharge conveyor 213 enters the conveying mechanism, which is used to break up the solid residue in the drying tank 21.

[0108] Specifically, the conveying mechanism can be a screw conveyor, which includes a crushing drive source and a guide. The crushing drive source can be a rotary motor, and the guide is a helical blade. The output end of the crushing drive source is connected to the guide, which drives the guide to rotate, allowing the helical guide to guide the solid residue along a helical trajectory to discharge the solid residue to the outside of the drying tank 21. During the conveying process, the compression, shearing, and collision effects on the solid residue also contribute to a certain degree of crushing.

[0109] In this manner, the spiral-structured guide can move the solid residue away from the discharge port 213 of the drying tank 21, preventing the solid residue from accumulating at the discharge port 213 of the drying tank 21. When the solid residue moves along the spiral trajectory, it has a certain tendency to tumble and move up and down, which produces a certain impact effect, which is beneficial to the crushing of the solid residue.

[0110] In one embodiment, such as Figure 1 As shown, the drying mechanism 2 also includes a drying drive source 24 and a transmission shaft 23. The drying drive source 24 can be a drive motor. The drying drive source 24 is located outside the drying tank 21. The output end of the drying drive source 24 is connected to the transmission shaft 23. The transmission shaft 23 passes through the drying component 22. The drying drive source 24 can drive the drying component 22 to rotate relative to the drying tank 21 through the transmission shaft 23, thereby realizing the stirring process of the drying component 22.

[0111] Specifically, such as Figures 1-2As shown, the drying assembly 22 includes a receiving plate 221, a first stirring component 222, a heating plate 223, and a second stirring component 224. The receiving plate 221 and the heating plate 223 are arranged in parallel and spaced apart. The first stirring component 222 is located on the side of the receiving plate 221 facing the liquid inlet 211, the heating plate 223 is located on the side of the receiving plate 221 away from the liquid inlet 211, and the second stirring component 224 is located between the receiving plate 221 and the heating plate 223.

[0112] For example, the receiving plate 221 and the heating plate 223 can be of disc structure. Along the axial direction of the drying tank 21, the receiving plate 221 and the heating plate 223 are arranged vertically, with the receiving plate 221 located above the heating plate 223. The raw materials to be separated can pass through the receiving plate 221 and the heating plate 223 in sequence.

[0113] For example, the raw material to be separated on the receiving tray 221 can fall to the heating tray 223 through the edge of the receiving tray 221; or, the receiving tray 221 has a discharge port, through which the raw material to be separated can fall to the heating tray 223.

[0114] For example, along the axial direction of the drying tank 21, the drive shaft 23 passes through the first stirring component 222, the receiving plate 221, the second stirring component 224, and the heating plate 223 from top to bottom, thereby realizing the synchronous rotation of the two discs and the two stirring components. At the same time, by using one drive shaft 23 to drive the movement of multiple components, the number of transmission components is relatively small, the failure rate is relatively low, which is beneficial to the stability of long-term operation.

[0115] For example, along the axial direction of the drying tank 21, a first stirring component 222 is located above the receiving plate 221. The first stirring component 222 is used to stir the raw material to be separated located above the receiving plate 221, thereby dispersing the raw material. A second stirring component 224 is located above the heating plate 223. The second stirring component 224 is capable of stirring the raw material to be separated located between the receiving plate 221 and the heating plate 223.

[0116] Specifically, the feeding mechanism 4 sprays the raw material to be separated into the drying assembly 22. The receiving tray 221 can receive the raw material to be separated. The first stirring component 222 stirs the raw material to be separated on the receiving tray 221, making the raw material to be separated uniformly mixed and evenly distributed on the receiving tray 221. The heating tray 223 is configured to receive and heat the raw material to be separated that has been stirred by the first stirring component 222 and output from the receiving tray 221, causing the raw material to be separated to evaporate into solid residue and steam. The second stirring component 224 can stir the raw material to be separated located between the receiving tray 221 and the heating tray 223, increasing the contact area between the raw material to be separated and the heating tray 223, and improving the heating efficiency. At the same time, the second stirring component 224 also plays a role in cleaning the heating tray 223 to a certain extent, preventing solid residue from adhering to the heating tray 223, reducing the downtime for cleaning the drying assembly 22, and ensuring the continuity of production of the entire separation system.

[0117] In one embodiment, such as Figure 2 As shown, along the axial direction of the drying tank 21, the top surface area of ​​the receiving plate 221 is smaller than the top surface area of ​​the heating plate 223.

[0118] For example, the size of the upper receiving plate 221 is smaller than the size of the lower heating plate 223; that is, the receiving plate 221 can be referred to as the small disc, and the heating plate 223 can be referred to as the large disc. The larger heating plate 223 is located below the smaller receiving plate 221, which allows the heating plate 223 to receive the raw material to be separated from the receiving plate 221 to the maximum extent and to increase the heating range of the raw material to be separated.

[0119] Specifically, such as Figures 2-4 As shown, the first stirring component 222 includes a first fixing rod 2221 and a first scraper 2222. The first fixing rod 2221 is arranged radially along the drying tank 21. Exemplarily, the first fixing rod 2221 is connected to the peripheral sidewall of the drive shaft 23. The first scraper 2222 is disposed on the side of the first fixing rod 2221 facing the receiving plate 221. The first scraper 2222 is used to clean and guide the raw material to be separated on the receiving plate 221. The receiving plate 221 is provided with a first discharge through hole 2211. The first scraper 2222 is inclined relative to the first fixing rod 2221. Exemplarily, the first scraper 2222 is inclined downward toward the first discharge through hole 2211. The first scraper 2222 is used to guide the raw material to be separated to the first discharge through hole 2211.

[0120] For example, the number of first fixing rods 2221 can be one or more. For instance, three first fixing rods 2221 are arranged along the circumferential direction of the drive shaft 23, and the included angle between two adjacent first fixing rods 2221 can be 60°. The number of first scrapers 2222 corresponding to each first fixing rod 2221 can be one or more. For instance, three first scrapers 2222 are distributed along the radial direction of the drying tank 21 and are arranged in parallel intervals, which helps to increase the cleaning range of the first stirring component 222.

[0121] For example, the first feeding through hole 2211 can be a circular or rectangular through hole, or the first feeding through hole 2211 can be a notch recessed inward along the edge of the peripheral side wall of the receiving plate 221.

[0122] In this manner, the drying drive source 24 drives the first fixed rod 2221 and the first scraper 2222 to rotate relative to the drying tank 21 through the transmission shaft 23. The first scraper 2222 can clean the raw material to be separated on the top surface of the receiving plate 221. Under the guidance of the inclined first scraper 2222, the raw material to be separated can be guided to the first discharge hole 2211, so that the raw material to be separated can fall into the heating plate 223 through the first discharge hole 2211. The raw material to be separated can be concentrated in the heating plate 223 for heating, reducing the risk of material leakage and improving the heating effect of the heating plate 223.

[0123] In one embodiment, such as Figures 2-3 As shown, the first stirring component 222 also includes a first mounting rod 2223 and a first rake column 2224. The first mounting rod 2223 is arranged along the radial direction of the drying tank 21 and is distributed with the first fixing rod 2221 along the circumferential direction of the drying tank 21. The first rake column 2224 is disposed on the side of the first mounting rod 2223 facing the receiving plate 221, and the first rake column 2224 extends along the axial direction of the drying tank 21.

[0124] For example, the number of first mounting rods 2223 can be one or more. For instance, two first mounting rods 2223 are arranged along the circumferential direction of the drive shaft 23, and the included angle between the two first mounting rods 2223 can be 180°. The first mounting rods 2223 are disposed between two adjacent first fixed rods 2221. The number of first rake columns 2224 corresponding to each first mounting rod 2223 can be one or more. For instance, three first rake columns 2224 are distributed along the radial direction of the drying tank 21 on the first mounting rods 2223, which helps to increase the cleaning range of the first stirring component 222.

[0125] If the adhesion between the raw material to be separated and the receiving tray 221 is relatively strong, the drying drive source 24 drives the first rake column 2224 to rotate relative to the drying tank 21 via the drive shaft 23 and the first mounting rod 2223. The first rake column 2224 can clean the raw material to be separated from the top surface of the receiving tray 221. Since the first rake column 2224 extends along the axial direction of the drying tank 21, it can directly scrape the raw material to be separated adhering to the receiving tray 221, which is beneficial for separating the raw material from the receiving tray 221.

[0126] In one embodiment, such as Figure 5 As shown, the heating plate 223 has a medium inlet 2232 and a medium outlet 2233 on its peripheral sidewall. The heating plate 223 has a heating cavity inside, which is connected to the medium inlet 2232 and the medium outlet 2233. The medium inlet 2232 is used to introduce heating medium into the heating cavity, and the medium outlet 2233 is used to discharge the heating medium in the heating cavity.

[0127] For example, the heating medium can be heat transfer oil, with a heating temperature of approximately 215°C. The heating medium, introduced through the medium inlet 2232, passes through the heating chamber and is discharged from the medium outlet 2233, ensuring that the heating plate 223 can maintain a certain temperature continuously, thus guaranteeing the heating effect of the heating plate 223. At the same time, the heating medium can fill the entire heating chamber, improving the uniformity of heating the raw materials to be separated by the heating plate 223.

[0128] In one embodiment, such as Figures 6-7 As shown, the second stirring component 224 includes a second fixing rod 2241 and a second scraper 2242. The second fixing rod 2241 is arranged along the radial direction of the drying tank 21. The second scraper 2242 is arranged on the side of the second fixing rod 2241 facing the heating plate 223. The heating plate 223 is provided with a second discharge through hole 2231. The projection of the second discharge through hole 2231 on the heating plate 223 does not coincide with the projection of the first discharge through hole 2211 on the heating plate 223. The second scraper 2242 is inclined relative to the second fixing rod 2241. The inclination direction of the second scraper 2242 is different from that of the first scraper 2222. The second scraper 2242 is used to guide the raw material to be separated to the second discharge through hole 2231.

[0129] For example, the number of second fixing rods 2241 can be one or more. For instance, three second fixing rods 2241 are arranged along the circumferential direction of the drive shaft 23, and the included angle between two adjacent second fixing rods 2241 can be 60°. The number of second scrapers 2242 corresponding to each second fixing rod 2241 can be one or more. For instance, three second scrapers 2242 are distributed along the radial direction of the drying tank 21 on the second fixing rods 2241, which helps to increase the cleaning range of the second stirring component 224.

[0130] For example, the second discharge through-hole 2231 can be a circular, rectangular, or other through-hole structure. The second discharge through-hole 2231 can also be a notch recessed inward along the edge of the heating plate 223. The projections of the first discharge through-hole 2211 and the second discharge through-hole 2231 on the heating plate 223 do not coincide, that is, the first discharge through-hole 2211 and the second discharge through-hole 2231 are misaligned to avoid the situation where the raw material to be separated conveyed from the first discharge through-hole 2211 is output from the second discharge through-hole 2231 without being heated by the heating plate 223.

[0131] Specifically, when the raw material to be separated on the receiving plate 221 falls into the heating plate 223 through the first discharge hole 2211, the heating plate 223 heats the raw material to be separated, forming fixed residue and steam. The steam can be discharged through the air outlet 212. The drying drive source 24 drives the second scraper 2242 to rotate relative to the drying tank 21 through the drive shaft 23 and the second fixed rod 2241. The second scraper 2242 can clean the fixed residue on the heating plate 223. Under the guidance of the inclined second scraper 2242, the fixed residue can be guided to the second discharge hole 2231, so that the fixed residue can fall through the second discharge hole 2231.

[0132] Wherein, along the radial direction of the drying tank 21, the first discharge through hole 2211 is provided on the side of the receiving plate 221 away from the central axis of the drying tank 21; and / or, along the radial direction of the drying tank 21, the second discharge through hole 2231 is provided on the side of the heating plate 223 facing the central axis of the drying tank 21.

[0133] For example, the first feeding through hole 2211 is located near the edge of the receiving plate 221, and the first scraper 2222 guides the raw material to be separated to move towards the edge of the receiving plate 221, that is, the first scraper 2222 scrapes the raw material to be separated outward; the second feeding through hole 2231 is located near the center of the heating plate 223, and under the guidance of the second scraper 2242, the solid residue formed by the heating of the raw material to be separated by the heating plate 223 can move towards the center of the heating plate 223, that is, the second scraper 2242 scrapes the solid residue inward.

[0134] In one embodiment, such as Figures 6-7 As shown, the second stirring component 224 further includes a second mounting rod 2243 and a second rake column 2244. The second mounting rod 2243 is arranged along the radial direction of the drying tank 21 and distributed with the second fixing rod 2241 along the circumferential direction of the drying tank 21. The second rake column 2244 is disposed on the side of the second mounting rod 2243 facing the heating plate 223, and extends along the axial direction of the drying tank 21.

[0135] For example, the number of second fixing rods 2241 can be one or more. For instance, two second fixing rods 2241 are arranged along the circumferential direction of the drive shaft 23, and the included angle between the two second fixing rods 2241 can be 180°. The second fixing rods 2241 are disposed between two adjacent second fixing rods 2241. The number of second rake columns 2244 corresponding to each second fixing rod 2241 can be one or more. For instance, three or six second rake columns 2244 are distributed on the second fixing rods 2241 along the radial direction of the drying tank 21, which helps to increase the cleaning range of the second stirring component 224.

[0136] If the adhesion between the raw material to be separated and the heating plate 223 is relatively strong, the drying drive source 24 drives the second rake column 2244 to rotate relative to the drying tank 21 via the transmission rod and the second fixed rod 2241. The second rake column 2244 can clean the fixed residue on the top surface of the heating plate 223. Since the second rake column 2244 extends along the axial direction of the drying tank 21, it can directly scrape the fixed residue adhering to the heating plate 223, which is beneficial for removing the fixed residue from the heating plate 223.

[0137] In one embodiment, such as Figure 2 As shown, there are multiple drying components 22, which are arranged along the axial direction of the drying tank 21. The raw material to be separated is stirred and dried by multiple drying components 22, which has a multi-stage drying effect. The raw material to be separated carried by the solid residue can be further dried by the next drying component 22, which improves the separation of the raw material to be separated and thus ensures the purity of the final 1,5-pentanediamine product.

[0138] Along the axial direction of the drying tank 21, the drying component 22 closest to the liquid inlet 211 among the multiple drying components 22 can receive the raw material to be separated output from the adjustment tank 1, and the drying component 22 on the side away from the liquid inlet 211 among two adjacent drying components 22 can receive the raw material to be separated output from the drying component 22 on the side closer to the liquid inlet 211.

[0139] For example, the number of multiple drying components 22 is four. The four drying components 22 are, from top to bottom, a first drying component, a second drying component, a third drying component, and a fourth drying component along the axial direction of the drying tank 21. The raw material to be separated, sprayed from the cloth mechanism 4, passes through the first drying component, the second drying component, the third drying component, and the fourth drying component in sequence to form a four-stage drying process. This not only enables the continuous separation of 1,5-pentanediamine but also yields a high-purity 1,5-pentanediamine product.

[0140] In one embodiment, such as Figure 2 and Figure 8As shown, along the axial direction of the drying tank 21, the top surface area of ​​the heating plate 223 that is close to each other in two adjacent drying components 22 is greater than the top surface area of ​​the receiving plate 221.

[0141] Since the size of the receiving plate 221 of each drying component 22 is smaller than the size of the heating plate 223, the receiving plates 221 and heating plates 223 in the multiple drying components 22 are staggered along the axial direction of the drying tank 21 and away from the liquid inlet 211. That is, along the axial direction of the drying tank 21 and away from the liquid inlet 211, there is a layer of smaller receiving plates 221, a layer of larger heating plates 223, a layer of smaller receiving plates 221, and a layer of larger heating plates 223, forming a staggered structure of small discs, large discs, small discs, and large discs.

[0142] Understandably, for two adjacent drying components 22, although the size of the upper heating plate 223 is larger than that of the lower receiving plate 221, the second discharge hole 2231 of the heating plate 223 is close to the center, causing solid residue to accumulate and be discharged towards the center of the heating plate 223. This prevents solid residue from leaking from the heating plate 223, thus preventing the lower receiving plate 221 from being unable to receive it. Simultaneously, because the heating plate 223 is larger, its heating range is also larger, improving the drying effect of the raw materials to be separated. Furthermore, the spaced arrangement of the receiving plate 221 and the heating plate 223 facilitates spatial arrangement within the drying tank 21.

[0143] In another embodiment, such as Figure 9 As shown, along the axial direction of the drying tank 21, the top surface area of ​​the heating plate 223 that is close to each other in two adjacent drying components 22 is smaller than the top surface area of ​​the receiving plate 221.

[0144] Since the size of the receiving plate 221 in each drying component 22 is smaller than the size of the heating plate 223, the sizes of the receiving plate 221 and the heating plate 223 in the multiple drying components 22 increase sequentially along the axial direction of the drying tank 21 and away from the liquid inlet 211, so that the multiple drying components 22 form a conical structure. That is, the receiving plate 221 located in the lower layer can directly receive the solid residue located in the adjacent upper heating plate 223, avoiding the situation where the solid residue located in the upper layer does not fall to the lower layer.

[0145] It is understood that in some other embodiments, the first discharge through hole 2211 may not be provided on the carrier plate 221, and the raw material to be separated on the carrier plate 221 may fall into the heating plate 223 through the edge of the carrier plate 221; the second discharge through hole 2231 may not be provided on the heating plate 223, and the raw material to be separated on the heating plate 223 may fall into the next layer carrier plate 221 through the edge of the heating plate 223.

[0146] Example

[0147] The raw material to be separated in the adjustment tank 1 is heated to 100°C by a temperature control component. The solid content of the raw material to be separated is 38%, the mass concentration of 1,5-pentanediamine in the raw material to be separated is 52%, and the pH is 12.5.

[0148] Driven by the feed pump 6, the raw material to be separated in the adjusting tank 1 is filtered by the filter 7 and then enters the spreading mechanism 4. The spreading mechanism 4 continuously sprays the raw material to be separated onto the bearing plate closest to the liquid inlet 211 in the drying component 22 with a fixed radius, forming a thin layer of raw material to be separated. The thickness of the raw material to be separated is about 8mm.

[0149] Under the action of vacuum component 5, a vacuum environment is formed inside the drying tank 21. The heating plate 223 of the drying component 22 heats the raw material to be separated, generating vapor containing 1,5-pentanediamine and solid residue. The vapor containing 1,5-pentanediamine carries a small amount of residue out of the drying tank 21, and then the vapor containing 1,5-pentanediamine enters the condensation mechanism 3, where it condenses to form a liquid.

[0150] The condensed liquid was passed into the refining unit 8 for distillation to obtain 1,5-pentanediamine. The purity and color of the obtained 1,5-pentanediamine product are shown in Table 1. The bottom temperature of the distillation column was 107℃, the top temperature was 86℃, the pressure was -0.08MPa, and the reflux ratio was 2:1.

[0151] In addition, as 1,5-pentanediamine is vaporized, the remaining solid residue in the drying tank 21 falls freely to the discharge conveyor 213 of the drying tank 21. The conveying mechanism rotates the solid residue in a spiral to crush it and obtain solid particles. The test results of the residual amount of 1,5-pentanediamine in the solid particles are shown in Table 1.
