[0004] In view of this, the utility model provides a separation device for a refined valine solution, which performs pretreatment on the refined solution during separation, further removes impurities in the solution, and improves the separation and purification efficiency in a subsequent purification process.

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: A separation device for a purified valine solution, such as Figure 1-5 As shown, the device comprises a housing 1, which serves as a supporting frame for the entire device. A filter cartridge 2 and a concentrator cartridge 3 are securely mounted on the left and right sides of the front portion thereof. A liquid inlet pipe 22 is cleverly provided on the upper side wall of the filter cartridge 2 for introducing the valine solution to be treated into the device. A filter element 21 is vertically mounted inside the filter cartridge 2, and an annular gap is cleverly maintained between its outer wall and the inner wall of the filter cartridge 2. This design allows one end of the liquid inlet pipe 22 to smoothly pass through the housing 1 into the filter cartridge 2 and communicate with this annular gap. The filter element 21 consists of a sturdy frame and a flexible filter membrane. This design not only ensures the structural strength of the filter element, but also enables the filter membrane to flexibly adapt to pressure changes during the filtration process.

[0023] When the valine solution enters the annular space between the filter element 21 and the filter cartridge 2 through the liquid inlet pipe 22, the impurities and particles in the solution are effectively blocked by the filter membrane of the filter element 21, while the pure valine solution smoothly penetrates the filter membrane and enters the interior of the filter element 21. At this time, the guide tube 4 passing through the lower part of the filter cartridge 2 plays a key role. It guides the pure solution in the filter element 21 into the concentration cylinder 3. The pump body equipped on the guide tube 4 provides powerful power to ensure the smooth flow of the solution.

[0024] The heating ring 31 at the lower inner part of the concentration cylinder 3 is another core component of the equipment. The interior of the heating ring 31 is hollow, which is convenient for the circulation of heat flow. One end of the two thermal energy joints 32 is connected to and connected to the heating ring 31, and the other end passes through the concentration cylinder 3 to the outside. It is closely connected to the external heat flow circulation equipment through the thermal energy joints 32, and the heat flow is continuously introduced into the heating ring 31 to provide the necessary heat for the concentration process. These heat flows pass through the right side of the shell 1, forming a complete heat flow circulation path.

[0025] In order to further optimize the concentration effect, the upper part of the concentration cylinder 3 is also connected and communicated with a pressure joint 33, which is connected to an external pressure control device. By precisely adjusting the pressure inside the concentration cylinder 3, the heated liquid in the concentration cylinder can be boiled under lower temperature conditions. This pressure control design enables the equipment to adapt to valine solutions of different concentrations and properties, enhancing the versatility and flexibility of the equipment.

[0026] A condenser 6 is provided on the rear side of the interior of the shell 1. The recovery pipe 5 on the top of the concentration cylinder 3 guides the water evaporated during concentration into the condenser 6. Through the cooling effect of the condenser 6, the steam and volatile components in the solution are condensed into liquid, thereby obtaining condensed liquid. The drain pipe provided on the condenser 6 is convenient for discharging the condensate out of the equipment for use in other subsequent processes.

[0027] In addition, the lower part of the concentration cylinder 3 and the filter cylinder 2 are both provided with a lower discharge pipe, which is used to discharge the waste liquid and concentrated solvent in the concentration process respectively, so as to keep the equipment clean and operate efficiently.

[0028] Example 2: Based on Example 1, Figure 2-5 As shown, the separation equipment for the purified valine solution has been further optimized and upgraded, with several key components added to enhance its functionality and efficiency. First, a water tank 7 has been added to the rear of the housing 1, near the condenser 6. This design cleverly utilizes the space layout. One end of the water tank 7 is connected to an external discharge pipe 71 for draining the liquid inside the tank. More importantly, the discharge pipe of the condenser 6 is connected to the interior of the water tank 7. This means that the purified liquid after being treated by the condenser 6 can flow directly into the water tank 7 for temporary storage or further processing, thereby simplifying the process and improving efficiency.

[0029] In order to further improve the heating effect, Figure 5 As shown, a number of heat cores 8 are spaced apart within the heating ring 31. These heat cores 8 are vertically mounted within the concentrator cylinder 3. Their interiors are hollow and connected to the interior of the heating ring 31. When heat flow is connected to the thermal connector 32, this heat flow is evenly transmitted to all heat cores 8 through the heating ring 31, allowing the solution in the concentrator cylinder 3 to be heated more evenly and efficiently, thereby improving concentration efficiency and quality.

[0030] In addition, in order to increase the flexibility and adaptability of the equipment, a temporary storage tube 9 and its related pipelines are added. The temporary storage tube 9 is located at the rear part of the shell 1 near the water tank 7, and is provided with a diverter pipe 90 connected to the guide pipe 4. A diverter valve 93 is installed at the connection between the diverter pipe 90 and the guide pipe 4 to control the flow direction and flow of the solution. A liquid outlet pipe 91 is also pierced through the wall of the temporary storage tube 9, one end of which is connected to the inside of the temporary storage tube 9, and the other end is connected to the upper part of the guide pipe 4. A liquid pump 92 is provided on the pipeline of the liquid outlet pipe 91 to provide power to draw the solution back from the temporary storage tube 9 to the guide pipe 4. This design enables the equipment to flexibly adjust the flow direction and flow of the solution according to actual needs, thereby meeting different process requirements.

[0031] Finally, in order to extend the service life of the filter element 21 and maintain its filtration efficiency, an energy storage component 10 is added to the top of the filter cartridge 2. Backflush pipes 102 are vertically provided at the upper and lower parts of the energy storage component 10. These backflush pipes 102 penetrate downward into the interior of the filter cartridge 2 and are used to backflush the filter element 21 when needed. A medium connector 101 is also vertically provided at the top of the filter cartridge 2, one end of which is connected to an external cleaning medium source, and the other end penetrates the filter cartridge 2 and is connected to the energy storage component 10. When the filter element 21 needs to be cleaned, it is only necessary to inject the cleaning medium into the energy storage component 10 through the media connector 101, and then use the energy stored in the energy storage component 10 and the guiding effect of the backflush pipe 102 to efficiently backflush the filter element 21, thereby restoring its filtration efficiency and extending its service life.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
