[0002] Low-temperature vacuum evaporators are common industrial equipment, widely used in pharmaceuticals, chemicals, food, electronics, and other fields. They utilize a vacuum pump to remove air from a container and maintain a negative pressure, allowing volatile materials to diffuse into the container. The materials are then evaporated through the heating element and metal heat transfer surfaces. In a vacuum environment, liquids can evaporate at lower temperatures, preventing the damage to solvents or solutes caused by high temperatures.

However, actual use of similar devices has revealed some drawbacks, such as:
[0004] After prolonged use, the heating chamber of the circulating heating assembly described in the referenced document accumulates a large amount of impurities and sediment. To maintain the heating efficiency of the circulating heating assembly, the heating chamber must be cleaned regularly. However, the heating chamber in the referenced document is integrated into the base, making it difficult to disassemble for cleaning. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0022] Reference Figure 1-6 A low-temperature vacuum evaporator capable of rapid preheating comprises a base 1, with a heat preservation tank 3 fixedly mounted above the base 1 via support columns. A low-temperature vacuum evaporator body 11 is disposed within the heat preservation tank 3. A detachable heating box 2 is disposed above the base 1 and on one side of the low-temperature vacuum evaporator body 11. A first water inlet pipe 21 and a first water outlet pipe 22 are fixedly mounted on the heating box 2, and a second water inlet pipe 31 and a second water outlet pipe 32 are mounted on the heat preservation tank 3. The first and second water inlet pipes 21 and 31 are connected to the first and second water outlet pipes 22 and 32, respectively, via adjustment seats 4.
[0023] The outer sides of the ends of the first water inlet pipe 21 and the first water outlet pipe 22 are both provided with sub-threads 23 , and the second water inlet pipe 31 and the second water outlet pipe 32 are both provided with adaptive and continuous female threads 33 corresponding to the sub-threads 23 .
[0024] Among them, the outer sides of the first water inlet pipe 21 , the second water inlet pipe 31 , the first water outlet pipe 22 , and the second water outlet pipe 32 are all fixedly provided with fixing seats 5 , and the second water inlet pipe 31 and the second water outlet pipe 32 are both movably provided with adjustment seats 4 .
[0025] By moving the adjustment seat 4 between the sub-thread 23 and the female thread 33 , the first water inlet pipe 21 and the second water inlet pipe 31 or the first water outlet pipe 22 and the second water outlet pipe 32 can be fixedly connected through the adjustment seat 4 .
[0026] The top of the adjustment seat 4 is provided with a plurality of first limiting cavities 41 and second limiting cavities 42 , and the middle portion of the adjustment seat 4 is adapted to be provided with screw grooves corresponding to the sub-threads 23 and the female threads 33 .
[0027] The tops of the fixing bases 5 on the second water inlet pipe 31 and the second water outlet pipe 32 are each fixedly provided with an L-shaped fixing plate 51. A limit member 53 is provided at the bottom of each fixing plate 51 for vertical movement via a plurality of springs 52. Both the first limit cavity 41 and the second limit cavity 42 are adapted to fit within the limit member 53. The springs 52 push the limit member 53 downward, allowing it to be stably retained within the first limit cavity 41 and the second limit cavity 42.
[0028] A plurality of guide members 54 are fixedly disposed behind the stopper 53, and a vertical guide cavity 55 is formed on the fixing plate 51 to correspond to the guide members 54. The guide members 54 and the guide cavity 55 provide guidance for the stopper 53, thereby improving the stability of the stopper 53 during movement.
[0029] In this embodiment, the insulation tank 3 is sleeved on the outside of the low-temperature vacuum evaporator body 11, and a heating component is provided in the heating box. The heating component can heat the liquid in the heating box. The heated liquid can enter the insulation tank from the water inlet pipe through the pump body. The liquid then flows through the insulation tank and heats the low-temperature vacuum evaporator body 11, and then flows back to the heating box 2 through the water outlet pipe for reheating. This achieves heating of the outside of the low-temperature vacuum evaporator body 11, thereby increasing the preheating speed of the low-temperature vacuum evaporator body 11. It is worth noting that this is all prior art, and the specific structure and working method of the low-temperature vacuum evaporator body 11 and the heating box 2 have been disclosed on the market and in comparative documents, so they will not be elaborated on.
[0030] Furthermore, the water inlet pipe is composed of a first water inlet pipe 21 and a second water inlet pipe 31, and the water outlet pipe is composed of a first water outlet pipe 31 and a second water outlet pipe 32. When the user needs to disassemble and clean the heating box 2, they only need to remove the screws at the bottom of the heating box 2, and then separate the first water inlet pipe 21 and the second water inlet pipe 31, and separate the first water outlet pipe 31 and the second water outlet pipe 32, so that the heating box 2 can be disassembled.
[0031] When the user needs to separate the first water inlet pipe 21 from the second water inlet pipe 31, they simply lift the stopper 53 upward, separating it from the first stopper cavity 41. This releases the engagement between the stopper 53 and the adjustment seat 4. The user can then rotate the adjustment seat 4 toward the second water inlet pipe 31. When the adjustment seat 4 is rotated to the fixing seat 5 on the second water inlet pipe 31, the engagement between the first water inlet pipe 21 and the second water inlet pipe 31 is released. The user can then release the stopper 53, which automatically returns downward to the second stopper cavity 42 due to the elastic force of the spring 52, thereby re-securing the adjustment seat 4.
[0032] Since the connection structure in the water inlet pipe and the water outlet pipe is the same, the user can also use the same method to remove the first water outlet pipe 22 and the second water outlet pipe 32. When the user has completely disassembled the water inlet pipe and the water outlet pipe, the heating box 2 can be removed and cleaned.
[0033] Furthermore, when the user has finished cleaning the heating box 2, he only needs to install the heating box 2 on the base 1 again with screws. Then align the first water inlet pipe 21 and the second water inlet pipe 31 so that the sub-thread 23 and the female thread 33 are connected together. Then lift the limiter 53 upward so that the limiter 53 is no longer stuck in the second limiting cavity 42. Then the adjustment seat 4 can be rotated in the opposite direction so that the adjustment seat 4 moves to the fixed seat 5 on the first water inlet pipe 21. At this time, release the limiter 53. At this time, the limiter 53 can be automatically reset to the first limiting cavity 41 by the elastic force of the spring 52, thereby achieving the fixation of the adjustment seat 4, thereby achieving the fixed connection between the first water inlet pipe 21 and the second water inlet pipe 31. The connection structure between the first water outlet pipe 31 and the second water outlet pipe 32 is the same as that of the first water inlet pipe 21 and the second water inlet pipe 31, so the first water outlet pipe 31 and the second water outlet pipe 32 can also be connected in this way.
[0034] It is also worth noting that sealing sleeves are provided on the first water inlet pipe 21 and the first water outlet pipe 22 to ensure the sealing between the water inlet pipe and the water outlet pipe after connection.
[0035] In the present invention, the outside of the low-temperature vacuum evaporator body 11 can be heated by setting the heating box 2 and the insulation tank 3 to increase its preheating speed. By setting the water inlet pipe and the water outlet pipe of the heating box 2 as a detachable structure and cooperating with the setting of the adjustment seat 4, the heating box 2 can be removed, so that the user can clean it after removing it.
[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
