Description

Technical Field

[0001] The invention relates to the technical field of chitosan purification, in particular to a bubbling cooling crystallization device for chitosan purification. Background Art

[0002] At present, in order to cool and crystallize chitosan, chitosan is usually immersed in an oil tank to form oil-immersed chitosan, and cooling crystallization fins are set on the oil tank shell of the oil-immersed chitosan to increase the cooling and crystallization effect of chitosan. A fan is usually also configured, and the wind blown by the cooling crystallization fan acts on the cooling crystallization fins to further increase the cooling and crystallization effect. However, in high temperature conditions in summer or when chitosan is under high load conditions, if only relying on traditional cooling and crystallization methods (such as cooling crystallization fins and fans), it may be difficult to effectively cool and crystallize the heat source. Even if a circulating pump is installed, most of the chitosan oil outside the chitosan winding is circulated and cooled, which is less targeted. When the chitosan oil is cooled by natural convection or forced circulation, the oil flow may not be able to reach all hot spots evenly, resulting in excessive temperatures in certain parts of the winding, which will shorten the service life of the chitosan.

The upper side wall of the cooling device 1 extends to the interior of the cooling device 1. The liquid pump 3 has two functions. One is to add chitosan oil to the interior of the cooling device 1, and the other is to circulate and cool the chitosan oil inside the cooling device 1. The interior of the cooling device 1 is provided with a lower iron yoke 101 and an upper iron yoke 103. A winding 102 is provided between the lower iron yoke 101 and the upper iron yoke 103. The lower iron yoke 101 and the upper iron yoke 103 are hollow, providing a flow path for the chitosan oil, and providing an effective guarantee for the cooling crystallization of the upper and lower ends of the iron core and the winding 102. It also includes: Shunt cooling assembly: The shunt cooling assembly is arranged inside the cooling device 1, and the shunt cooling assembly uses chitin oil to perform surrounding cooling on the heat source center of the winding 102 and the inside of the cooling device 1; Hydraulic transmission assembly: The hydraulic transmission assembly is arranged inside the split cooling assembly, and the hydraulic transmission assembly utilizes the flow of chitin oil to speed up the cooling efficiency of the winding 102; Pneumatic suspension assembly: The pneumatic suspension assembly is arranged on the hydraulic transmission assembly. The pneumatic suspension assembly changes its density according to the temperature of the chitin oil and starts the circulation of the chitin oil flow when the temperature reaches a threshold value; Turbine cleaning assembly: The spoiler cleaning assembly is arranged outside the pneumatic suspension assembly, and the spoiler cleaning assembly increases the contact area between the inside of the split cooling assembly and the chitin oil; Furthermore, the shunt cooling assembly includes a liquid guide tube 4 and a liquid guide branch tube 401, which are respectively connected to the inner cavities of the lower iron yoke 101 and the upper iron yoke 103, and the ends of the liquid guide tube 4 and the liquid guide branch tube 401 extend to the upper part of the upper iron yoke 103 and the lower part of the lower iron yoke 101, respectively. The upper end of the liquid guide tube 4 is connected to the end of the liquid infusion tube 302 extending to the interior of the cooling device 1, ensuring that the chitin oil transported through the liquid infusion tube 302 directly enters the interior of the shunt cooling assembly; It should be noted that: the inner diameters of the liquid guide pipe 4 and the liquid guide branch pipe 401 are equal, and the side wall of the liquid guide branch pipe 401 located inside the lower iron yoke 101 is provided with a plurality of outlets 402, and the plurality of outlets 402 are equidistantly distributed in a ring shape around the central axis of the liquid guide branch pipe 401, ensuring that the chitosan oil entering the liquid guide branch pipe 401 can enter the inner cavity of the lower iron yoke 101 through the outlet 402, so as to effectively cool and crystallize the winding 102 and the bottom end of the iron core, and the upper and lower ends of the liquid guide branch pipe 401 are fixedly installed with a filter 403 to filter the chitosan oil entering the inside of the shunt cooling component, so as to ensure the heat exchange efficiency of the shunt cooling component to the winding 102 and the inner side of the iron core; Reference Figure 9-Figure 14The hydraulic transmission assembly includes a plurality of transmission magnetic rods 5 and a plurality of limit frames 502. The transmission magnetic rods 5 are fixedly connected with impact blades 501 and limit rings 503. The transmission magnetic rods 5 are rotatably connected with the limit frames 502 through the limit rings 503. The plurality of limit frames 502 are respectively fixedly connected with the inner cavity side walls of the liquid guide tube 4 or the liquid guide branch tube 401. The impact blades 501 are located directly above the limit frames 502. The impact blades 501 located directly above the liquid guide tube 4 are arranged opposite to the port of the liquid infusion tube 302. The impact blades 501 are inclined and light-weighted, which optimizes the rotational dynamics performance under the impact of chitin oil. This design not only reduces the moment of inertia, but also improves the response speed and driving efficiency. When the chitin oil flows out of the liquid infusion tube 302, a portion of the chitin oil will directly The impact blade 501 at the liquid guide tube 4 is impacted by the other part, and the other part flows through the inner cavity of the upper iron yoke 103 and impacts the impact blade 501 at the liquid guide tube 401. When the corresponding impact blade 501 rotates, the transmission magnetic rod 5 connected thereto will rotate accordingly. The ends of the transmission magnetic rod 5 located in the liquid guide tube 401 extend to the outside of the port of the liquid guide tube 401 respectively. The ends of the transmission magnetic rod 5 located in the liquid guide tube 401 penetrate the filter screen 403 and are fixedly connected with a scraper 504. A soft brush is fixedly arranged on the side wall of the scraper 504 facing the filter screen 403. The gap between the filter screen 403 and the scraper 504 is small. When the transmission magnetic rod 5 rotates, the scraper 504 drives the soft brush to rotate on the filter screen 403 to scrape off the oil stains on the filter screen 403 to prevent it from being blocked. Furthermore, the pneumatic suspension assembly includes a sliding magnetic cylinder 6 slidably connected to the transmission magnetic rod 5, an installation cavity 601 is arranged inside the sliding magnetic cylinder 6, a connecting spring 602 is fixedly connected to the bottom wall of the installation cavity 601, a piston disc 603 is fixedly connected to the upper end of the connecting spring 602, a trigger switch 604 is fixedly arranged on the top of the inner cavity of the installation cavity 601, the piston disc 603 is sealed and slidably connected to the installation cavity 601, and high-pressure nitrogen is filled between the bottom wall of the piston disc 603 and the inner cavity of the installation cavity 601. When the temperature of the chitosan oil inside the cooling device 1 is low (the chitosan load is low or no load), the sliding magnetic cylinder 6 will float at the bottom end of the liquid guide tube 4 under the action of gravity. When the temperature of the chitosan oil inside the cooling device 1 is high (the chitosan load is high), the high-pressure nitrogen filled between the bottom wall of the piston disc 603 and the inner cavity of the installation cavity 601 will expand due to heat (increase in volume), and accordingly, the density of the sliding magnetic cylinder 6 will decrease accordingly. At this time, the buoyancy of the sliding magnetic cylinder 6 is greater than the gravity, and it will slide upward along the transmission magnetic rod 5. It should be noted that: the transmission magnetic rod 5 and the sliding magnetic cylinder 6 are set with different polarity magnetism. When the transmission magnetic rod 5 rotates, the sliding magnetic cylinder 6 will rotate accordingly under the drive of magnetic force. The sliding magnetic cylinder 6 located inside the liquid guide tube 4 is located below the limit frame 502, and the sliding magnetic cylinder 6 located inside the liquid guide branch 401 is located between the two limit frames 502. The limit frame 502 can limit the transmission magnetic rod 5 on the one hand, and the sliding magnetic cylinder 6 can be limited on the other hand. The trigger switch 604 is electrically connected to the liquid pump 3. When the piston disc 603 squeezes the trigger switch 604, it means that the temperature inside the chitin is high. The trigger switch 604 will control the start of the liquid pump 3 to strengthen the circulation of the chitin oil inside the cooling device 1. The height of the sliding magnetic cylinder 6 is greater than the height of the inner cavity of the lower iron yoke 101. There is a gap between the side wall of the sliding magnetic cylinder 6 and the side wall of the liquid guide tube 4 or the liquid guide branch 401, ensuring that the chitin oil can pass through the gap; Further, the turbulence cleaning assembly includes a plurality of floating transverse plates 8 fixedly connected to the outer wall of the sliding magnetic cylinder 6, and the plurality of floating transverse plates 8 are equidistantly distributed in a ring around the central axis of the corresponding sliding magnetic cylinder 6. The upper and lower side walls of the floating transverse plates 8 are respectively fixedly connected with a fan-shaped clamping plate 7 and a filter plate 9. The floating transverse plates 8 play a connecting role on the one hand, and can increase the buoyancy of the sliding magnetic cylinder 6 on the other hand, so as to timely respond to changes in the temperature of the chitin oil. The fan-shaped clamping plate 7 is composed of two arc-shaped plates, and the fan-shaped clamping plate 7 is set to be large at one end and small at the other end. The arc-shaped plate located on the inner side is sealed and connected to the side wall of the filter plate 9; It should be noted that: a sewage outlet 701 is provided at the ends of the two arc-shaped plates, and the outer wall of the fan-shaped clamping plate 7 is against the inner wall of the liquid guiding tube 4 or the liquid guiding branch 401. When the sliding magnetic cylinder 6 rotates, the fan-shaped clamping plate 7 can scrape and clean the oil on the liquid guiding tube 4 or the liquid guiding branch 401, and finally discharge it through the sewage outlet 701 to ensure the contact area between the liquid guiding tube 4 and the liquid guiding branch 401 and the chitosan oil, ensuring that the winding 102 and the inner side of the core can be fully cooled. A plurality of groups of rectangular windows are equidistantly arranged on the filter plate 9, and the ends of the rectangular windows pass through the side walls of the filter plate 9. Through the setting of the sewage outlet 701 and the rectangular windows, the oil flow in the liquid guiding tube 4 or the liquid guiding branch 401 can be disturbed to achieve laminar flow characteristics and improve the cooling efficiency of the chitosan oil.

[0019] The working principle of the bubbling cooling crystallization device for chitosan purification is as follows: firstly, the chitosan oil can be added to the cooling device 1 through the liquid pump 3, which is crucial to keep the chitosan oil at an appropriate working level, because the amount of oil can change due to consumption or thermal expansion during normal operation, and maintaining the proper oil level is very important to ensure the cooling and insulation of the internal components of the chitosan, such as the iron core and the winding 102. On the other hand, the liquid pump 3 can extract the high-temperature chitosan oil from the cooling device 1 to the oil pillow 2 through the liquid pumping pipe 301, and circulate the cooled chitosan oil in the oil pillow 2 into the cooling device 1 through the liquid replenishing pipe 302. The chitosan oil not only serves as an insulating medium, but also can carry the heat generated by the iron core and the winding 102 to the inside of the oil pillow 2, so that the excess heat can be effectively dissipated to prevent the chitosan from overheating; When the chitosan oil is added to the cooling device 1, the cooled chitosan oil can be directly extracted from the oil pillow 2 through the liquid pump 3 and enter the split cooling assembly through the liquid replenishing pipe 302 (the valve at the liquid pump 301 is closed at this time), and the chitosan oil flows through the hollow structure of the lower iron yoke 101 and the upper iron yoke 103 arranged inside the chitosan. This design allows the oil flow to pass through the upper and lower ends of the iron core and the winding 102, effectively capturing and taking away the generated heat. The hollow iron yoke not only provides a path for the oil flow, but also provides a larger surface area for cooling crystallization, so that heat exchange can be performed more efficiently; At the same time, the chitosan oil flowing out through the liquid replenishment pipe 302 will directly impact the impact blade 501. Under the impact of the chitosan oil, the impact blade 501 will start quickly. This low moment of inertia design enables the blade to sensitively respond to changes in fluid force. The optimization of the rotational dynamics ensures that the impact blade 501 can effectively rotate even when there is a slight change in flow or pressure. When the chitosan oil impacts the blade 501 and rotates it, the transmission magnetic rod 5 connected to the blade will also rotate accordingly. The rotation of the transmission magnetic rod 5 will further drive the scraper 504, and then drive the soft brush to rotate on the filter 403 to scrape off the accumulated oil. This automatic cleaning mechanism reduces the maintenance requirements of the system, extends the service life of the filter 403, and maintains the flow of liquid and the heat exchange efficiency. Through this mechanism, the system can not only maintain the cleanliness of the chitosan oil, but also ensure the continuity of the oil flow, which is crucial for the cooling of chitosan. The clean oil flow can more effectively absorb heat from the iron core and the winding 102, and bring it to the oil pillow 2 for release; When the temperature of the chitosan oil inside the cooling device 1 is low (the chitosan load is low or no load), the sliding magnetic cylinder 6 will float at the bottom end of the liquid guide tube 4 under the action of gravity. When the temperature of the chitosan oil inside the cooling device 1 is high (the chitosan load is high), the high-pressure nitrogen filled between the bottom wall of the piston disc 603 and the inner cavity of the installation cavity 601 will expand due to heat (increase in volume), and accordingly, the density of the sliding magnetic cylinder 6 will decrease accordingly. At this time, the buoyancy of the sliding magnetic cylinder 6 is greater than the gravity, and it will slide upward along the transmission magnetic rod 5. When the temperature of the chitosan oil rises, the high-pressure nitrogen in the sliding magnetic cylinder 6 will expand due to the heat. At this time, the expanded high-pressure nitrogen will drive the piston disc 603 to move upward (overcoming the elastic force of the connecting spring 602), and finally cause it to counteract the trigger switch 604. Because the trigger switch 604 is electrically connected to the liquid pump 3, when the piston disc 603 squeezes the trigger switch 604, it means that the temperature inside the chitosan is high. The trigger switch 604 will control the liquid pump 3 to start to strengthen the circulation of the chitosan oil inside the cooling device 1. At this time, the liquid pump 3 can extract the high-temperature chitosan oil from the cooling device 1 to the oil pillow 2 through the liquid pumping pipe 301, and circulate the cooling chitosan oil pre-in the oil pillow 2 to the cooling device 1 through the liquid replenishing pipe 302; Since the oil flow introduced at a single time is large, most of the excess chitin oil will be discharged downward under the action of gravity, and discharged through the outlet 402 and the lower port of the liquid guide branch 401. On the other hand, since the volume of the inner cavity of the upper iron yoke 103 and the lower iron yoke 101 is a fixed value, a part of the oil flow will flow out through the upper end of the liquid guide branch 401. These two parts of the oil flow will eventually collide with the inner wall of the cooling device 1 and diverge to both sides (refer to Figure 5 ), the specific flow direction is to cool the entire winding 102, the upper iron yoke 103 and the lower iron yoke 101 from the inside out in an encircling manner. By guiding the oil flow in an organized manner, it can ensure that the key components inside the chitosan - the winding 102 and the iron yoke - are effectively cooled. This encircling encircling cooling method helps to evenly distribute the cooling crystallization amount and avoid local overheating, thereby improving the overall cooling efficiency, reducing the internal stress caused by the large temperature difference, and extending the service life of the chitosan. During the operation of the chitosan, the load may fluctuate greatly. This design allows more oil flow to flow in under high load conditions to provide enhanced cooling. This adaptive ability ensures that the chitosan can maintain a suitable operating temperature even when the load is high. By maximizing the chitosan oil flow to reduce the need to rely on external cooling systems, such as fans or coolers, this reduces energy consumption and operating costs to a certain extent; In particular, since the sliding magnetic cylinder 6 is sealed, the volume of its interior (installation cavity 601) remains unchanged, and as the temperature rises, the distance between nitrogen molecules increases, resulting in a decrease in density (the mass of the gas remains unchanged, the volume increases, density = mass / volume, so the density decreases). When the density of nitrogen decreases, the sliding magnetic cylinder 6 as a whole becomes lighter than the surrounding chitin oil, and the weight of the chitin oil it displaces (i.e., buoyancy) is greater than its own weight, thereby generating a net upward force. This net upward force is sufficient to overcome the sinking force of the sliding magnetic cylinder 6 and any other resistance (such as viscous resistance), and the sliding magnetic cylinder 6 will rise at this time. When the temperature decreases, the opposite is true. Because the transmission magnetic rod 5 and the sliding magnetic cylinder 6 are set with different polarity magnetism, when the transmission magnetic rod 5 rotates, the sliding magnetic cylinder 6 will rotate accordingly under the drive of magnetic force, that is, the sliding magnetic cylinder 6 will be in a floating and rotating state. When the sliding magnetic cylinder 6 rotates, the fan-shaped clamping plate 7 can continuously remove the oil on the liquid guide tube 4 or the liquid guide branch 401, and finally discharge it through the drainage port 701, so as to increase the contact area between the liquid guide tube 4, the liquid guide branch 401 and the chitosan oil, and ensure that the winding 102 and the inner side of the iron core can be fully cooled. The unique drainage port 701 design and the filter plate 9 structure increase the contact area between the oil flow and the cooling system by changing the flow path of the fluid, and improve the heat exchange efficiency. The laminar flow state of the oil flow can be maintained through the specially designed window and the drainage port 701. This flow state usually has a higher heat exchange efficiency than the turbulent state. The special design of the fan-shaped clamping plate 7 and the filter plate 9 optimizes the fluid dynamics effect and realizes more efficient heat transfer and dirt removal. In summary, the bubbling cooling crystallization equipment for chitosan purification realizes effective circulation and cleaning of the fluid through the hydraulic transmission component, and automatically adjusts the fluid flow through the pneumatic suspension component and the diversion cooling component to adapt to different working conditions. At the same time, the turbulence cleaning component optimizes the heat exchange efficiency and reduces cleaning and maintenance work. This design not only improves the cooling efficiency and reliability of chitosan, but also reduces the operation and maintenance costs. It is an efficient, adaptive and easy-to-maintain solution.
