Description

Technical Field

[0001] This utility model relates to the field of evaporation and concentration technology, and in particular to an evaporation and concentration device for preparing nasal spray. Background Technology

[0002] As a common nasal medication, nasal sprays require evaporation and concentration during preparation to remove excess solvent and increase drug concentration.

[0003] Existing evaporation and concentration devices typically employ direct heating or steam heating, using a heater to heat the liquid to a boiling state, thus evaporating and concentrating it. Common structures include a heating tank, a separation tank, and a condenser. After the liquid is heated in the heating tank, steam enters the separation tank through pipes for gas-liquid separation. The concentrated liquid is discharged from the bottom of the separation tank, while the steam is cooled by the condenser and either recovered or discharged. In existing technologies, the liquid typically enters the heating zone in the form of a water column or at a high flow rate, relying on natural flow or simple baffles for distribution.

[0004] However, in existing technologies, when liquid enters the heating zone in the form of a water column or at a high flow rate, it easily leads to uneven distribution of the liquid within the evaporator, with excessive liquid in some areas and insufficient liquid in others. This uneven distribution reduces evaporation efficiency, prolongs concentration time, and may even cause degradation or inactivation of drug components due to localized overheating. Therefore, an evaporation and concentration device for preparing nasal spray is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an evaporation and concentration device for preparing nasal spray, which aims to improve the problem in the prior art where the liquid flows into the heat exchange copper tube in a columnar manner, resulting in uneven distribution of the liquid in the evaporator, excessive liquid in some areas, and low evaporation efficiency.

The top of the sealing cover 25 is located at the bottom of the steam tank 2.

[0036] Working Principle: When using the evaporation and concentration device for preparing nasal spray, firstly, the nasal spray concentrate generator is connected to flange 13. Then, the liquid flows to the inner wall of the top pipe 8 and steam tank 2, and then into the outlet pipe 14. The nasal spray concentrate impacts the top of the distribution plate 15, dispersing it in an umbrella shape. Next, the nasal spray concentrate flows through the conical drip pipe 16 into the heat exchange copper pipe 11. Then, the compressor 3 generates steam, which is blown into the second connecting pipe 5 and then into the expansion ring 7. When the steam reaches the steam tank 2, it passes through a baffle. The staggered connection of 12 increases the flow time of steam inside the steam tank 2, and the high temperature of the steam evaporates the nasal spray concentrate on the inner wall of the heat exchange copper tube 11. Then, when the liquid steam tank 2 evaporates the nasal spray concentrate, the remaining steam and liquid are separated. The liquid flows into the interior of the separation tank 1 through the second flow pipe 10, while the steam is transferred into the interior of the separation tank 1 through the first flow pipe 9. The steam then connects one end of the separation tank 1 to the input end of the compressor 3, achieving the effect of evaporating and concentrating the nasal spray concentrate. At the same time, the setting of the baffle 12 increases the steam presence time, and the diverter plate 15 turns the nasal spray concentrate into an umbrella shape, improving the concentration efficiency of the evaporation and concentration device.

[0037] Next, when cleaning the steam tank 2, the output end of the hydraulic cylinder 19 drives the connecting block 20 to move. Then, the bottom of the connecting block 20 will move linearly along the center point of the hydraulic cylinder 19. When the connecting block 20 moves, it drives the first rotating plate 21 of the outer wall to rotate. Then, the rotation of the first rotating plate 21 drives the pressure plate 22 of the side wall to move. Next, when the pressure plate 22 is under force, it drives the third rotating plate 24 of the side wall to rotate on the side wall of the fixed column 29. The third rotating plate 24 will move in a circle along the central axis. In summary, when the connecting block 20 moves, it drives the second rotating plate 23 of the side wall to rotate. The second rotating plate 23 then connects the connecting block 20 and the third rotating plate 24. When the second rotating plate 23 is under force, it will move in a circle along the central axis of the side wall of the connecting block 20. Next, through the connection between the first rotating plate 21, the second rotating plate 23 and the third rotating plate 24, the side wall of the pressure plate 22 will be disengaged from the bottom of the sealing cover 25, achieving the effect of quickly disassembling the bottom of the steam tank 2.
