Description

Technical Field

[0001] This utility model relates to the field of centrifugal evaporation technology, specifically to a low-temperature high-speed centrifugal evaporation device. Background Technology

[0002] Centrifugation is a method of separating substances with different specific gravities using centrifugal force. Because centrifuges and similar equipment can generate very high angular velocities, the centrifugal force is much greater than gravity, making it easier for suspended solids in a solution to precipitate. Furthermore, since substances with different specific gravities experience different centrifugal forces, their settling velocities differ, enabling separation. Centrifugation is also a commonly used biochemical separation method for biomolecules, as different biomolecules have different volumes and densities and can settle and separate under varying centrifugal forces. Centrifugal evaporation is a technique that combines centrifugal force and evaporation principles. A larger evaporation area and optimized evaporation conditions can significantly shorten evaporation time and improve efficiency. However, existing centrifugal evaporation devices have a slow heating rate for the internal solution, making rapid evaporation of reagents inconvenient. Utility Model Content

[0007] Preferably, the cavity and the placement cavity are rotatably connected, and the placement cavity and the outer shell are rotatably connected.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a low-temperature high-speed centrifugal evaporation device, including a shell 10, a motor 20, a cavity 30, a placement cavity 40, a sealing cover 401, a lid 50, a heating block 60, a first pipe 601, a first check valve 602, a vacuum pump 603, a second pipe 604, and a second check valve 605.

[0030] This high-speed centrifugal evaporator improves the reaction rate of the device. The specific implementation method is as follows:

[0031] A motor 20 is embedded in the surface of the outer casing 10, and a cavity 30 is also embedded in the surface of the outer casing 10. A placement cavity 40 is installed inside the cavity 30, and the output shaft of the motor 20 is connected to the bottom surface of the placement cavity 40. A cover 50 is rotatably mounted on the surface of the outer casing 10, and a sealing cover 401 is installed at the bottom of the cover 50. The outer casing 10 is equipped with a heating structure, which includes: a heating block 60 embedded inside the outer casing 10; a first pipe 601 embedded in the surface of the cover 50, with a first check valve 602 installed inside the first pipe 601; a vacuum pump 603 mounted on the surface of the cover 50, with a second pipe 604 installed on the vacuum pump 603, and a second check valve 604 installed on the surface of the second pipe 604. 05. The cavity 30 and the placement cavity 40 are rotatably connected, and the placement cavity 40 is rotatably connected to the outer shell 10. The sealing cover 401 is embedded in the surface of the placement cavity 40, and the placement cavity 40 and the sealing cover 401 are rotatably connected. One side of the cover 50 is rotatably connected to the outer shell 10, and the outer shell 10 and the cavity 30 are positioned correspondingly. The heating block 60 is set as a ring structure, and the inner wall of the heating block 60 is positioned correspondingly to the placement cavity 40. The end of pipe one 601 passes through the sealing cover 401 and is inserted into the placement cavity 40. The end of pipe two 604 passes through the sealing cover 401 and is inserted into the placement cavity 40. Both pipe one 601 and pipe two 604 are connected to the placement cavity 40.

[0032] Rotate the lid 50, causing it to move the sealing cover 401 upwards, removing it from the placement cavity 40. At this point, solution can be added to the placement cavity 40. Then close the lid 50, causing it to move the sealing cover 401 downwards, bringing it to the top of the placement cavity 40 and sealing it. Start the vacuum pump 603, drawing a vacuum through pipe 604 to create negative pressure inside the placement cavity 40. Check valve 605 prevents gas backflow. Then start the motor 20 and heating block 60. The output shaft of motor 20 drives the placement... The placement chamber 40 rotates, causing it to rotate inside the cavity 30. At this time, the placement chamber 40 rotates at the bottom of the sealing cover 401, causing the internal solution to rotate and centrifuge. Simultaneously, the heat generated by the heating block 60 enters the placement chamber 40, heating the internal solution and causing it to evaporate.
