Technical Field
[0001] This utility model relates to the field of evaporators, and in particular to a highly stable lifting rotary evaporator. Background Technology
[0002] Evaporators are indispensable key equipment in numerous industrial fields such as chemistry, pharmaceuticals, and food, as well as in scientific research experiments. They are primarily used to evaporate solvents from solutions through heating, thereby achieving solute concentration, purification, or solvent recovery and reuse. Whether processing batches of solutions in large-scale industrial production or preparing small samples for precise analysis in the laboratory, evaporators play a crucial role. Their performance directly affects production efficiency, product quality, and the accuracy of experimental results, thus making them a key focus of technological research and equipment improvement in related fields.
[0003] Evaporators in the present technology typically consist of a heating unit, an evaporation flask, a condenser, and a vacuum unit. The technical principle is to use the heating unit to heat the evaporation flask containing the solution, causing the solution to reach its boiling point and the solvent to convert into vapor. Subsequently, the vapor enters the condenser, where it is cooled and condensed into liquid in the condenser tube, thus achieving the separation of solvent and solute. Simultaneously, the intervention of the vacuum unit can lower the boiling point of the solvent, accelerate the evaporation rate, and improve evaporation efficiency. However, existing evaporators have significant shortcomings in their lifting mechanism design. The lifting process often lacks an effective buffering mechanism, leading to sudden rises and falls in glass components such as evaporation flasks. This violent movement easily causes impact and vibration to the glass components, not only affecting the normal progress of experiments or production but also greatly increasing the risk of damage, causing unnecessary losses and safety hazards for users. Therefore, a highly stable lifting rotary evaporator is proposed to solve these problems. Utility Model Content

A feeding valve 7 is fixedly connected to one side of the condenser 6, allowing for continuous feeding without disrupting the vacuum of the components, thus improving the convenience and continuity of experimental operations. A connecting ring 19 is fixedly connected to the other side of the condenser 6. This connecting ring 19 is threadedly connected to a connecting ring 20, achieving quick assembly / disassembly and reliable sealing. The inner wall of the connecting ring 19 is threaded with the connecting ring 20. One end of the connecting ring 20 is fixedly connected to a connecting shell 13, which houses the rotating assembly and connects it to the control unit 3, creating a stable framework for power transmission. One side of the evaporating flask 10 is rotatably connected to the inner wall of the connecting shell 13. The unit, with one side of the connecting shell 13 fixedly connected to the outer wall of the control unit 3, includes a lifting assembly comprising a gas spring 12. This gas spring 12 provides smooth and stable lifting power, and its top buffer distance effectively prevents damage to the glass components during sudden rises or falls. The outer wall of the gas spring 12 is fixedly connected to the interior of the control unit 3, and the output end of the gas spring 12 is fixedly connected to the top of the base plate 1. A display screen 5 and a controller 11 are fixedly connected to one side of the control unit 3.

It supports forward and reverse rotation and timing functions, enhancing the flexibility and automation level of the experiment.Motor 14 is located on the outer wall of evaporating flask 10. The outer wall of motor 14 is fixedly connected to one side of connecting shell 13. Gear 15, gear 2 16, and gear 3 17 are rotatably connected inside connecting shell 13. The output end of motor 14 is fixedly connected to one end of gear 15. Gear 15 meshes with gear 2 16 and gear 3 17 to precisely transmit the power of motor 14 to evaporating flask 10.

Connecting shell 2 18 is located on the outer wall of evaporating flask 10.
[0018] Working Principle: Throughout the process, the material is placed in an evaporation flask 10 made of high borosilicate glass and immersed in a constant temperature bath 4 with high-precision intelligent PID temperature control for heating. This bath can be used for both water and oil and has an anti-dry-burning function. As the evaporation flask 10 rotates, the heated area of the material increases, and it evaporates rapidly under vacuum conditions. The generated vapor passes through a condenser 6, also made of high borosilicate glass, where it is rapidly condensed into liquid and flows into the collection bottle 9 below. The sealing of the entire component is ensured by imported fluororubber and a skeleton oil seal structure or optional modified PTFE double-lip seals. Their corrosion resistance, wear resistance, and high-temperature resistance solve the sealing problems under chemical corrosion and high temperatures, ensuring a safe and reliable experimental environment. Furthermore, the entire machine boasts an IP42 dust and water resistance rating and supports the Modbus communication protocol via a DB9 data interface, enhancing its automation integration capabilities and durability and intelligent performance in complex experimental environments. Ultimately, it provides users with a convenient, fast, safe, and reliable experimental experience. When adjusting the height between the evaporation flask 10 and the constant temperature bath 4, the operator issues a command through the controller 11 on the control unit 3, causing the gas spring 12 in the lifting assembly to smoothly push the control unit 3 against the outer wall of the fixed base 2. The gas spring 12's advantage lies in its specially designed buffer distance at the top, which solves the problem of glass damage caused by sudden rises or falls during traditional equipment, achieving smooth lifting and protecting expensive glass instruments. When adjusting the angle and rotation speed of the evaporation flask 10, the operator makes settings through the 4.5-inch LCD screen 5, which then activates its built-in DC brushless rotary motor 14. The motor 14 supports forward and reverse rotation and timed rotation functions. Its rotational power is smooth and stable. By driving gear 15, gear 2 16 and gear 3 17, it drives the evaporation flask 10 to rotate stably, which solves the problem of cracking of the outer wall of the evaporation flask 10 due to uneven heating on one side for a long time, and enhances the solvent evaporation efficiency and the uniformity of the process.
