Description

Technical Field

[0001] This utility model relates to the field of distillation column technology, specifically a distillation column that can be quickly assembled. Background Technology

[0002] In chemical production, distillation columns are often used to highly purify chemical products by extracting the components from a mixture. A distillation column separates the components based on their volatility, specifically the difference in vapor pressure at the same temperature. This allows lighter components (low-boiling compounds) in the liquid phase to transfer to the gas phase, while cooling causes heavier components (high-boiling compounds) in the gas phase to transfer to the liquid phase, thus separating the mixture and allowing for the centralized collection of purified compounds.

[0003] Chinese patent document CN214075124U discloses a distillation column, comprising a support, a column body mounted on the support, and a lifting device mounted on the column body. The lifting device includes two bidirectional screws arranged along the height direction of the column body, a first lifting layer on the bidirectional screws, a second lifting layer on the bidirectional screws, and a drive mechanism for rotating the bidirectional screws. The bidirectional screws are arranged along the height direction of the column body, and their two ends are rotatably connected to the column body. The first and second lifting layers are respectively wound around the column body and are arranged parallel to each other. This application uses a drive mechanism to move the first and second lifting layers along the height direction of the column body, facilitating maintenance and cleaning of the column body surface by personnel as needed.

[0004] The existing distillation column has inconvenient internal components that are difficult to install and disassemble, and the overall airtightness of the distillation column is poor, making it prone to leakage. Therefore, it is necessary to develop a distillation column that can be quickly assembled. Utility Model Content

[0007] Preferably, the sealing cover and the distillation column body are fixed together by a locking component, which includes a fixed shaft pin, a locking nut, a limiting plate, a fixed clamping plate, and a movable shaft.

[0008] Preferably, multiple fixing plates are provided, and the fixing plates are symmetrically arranged in pairs on the side surfaces of the sealing cover and the distillation column body. The fixing plates on the distillation column body are connected to the fixing shaft pins through the movable shaft.

[0009] Preferably, the upper end of the fixed shaft pin is connected to the limiting plate by a locking nut, and the limiting plate is engaged and fixed with the fixed clamp plate provided on the sealing cover.
