Abstract
Description
Technical Field
[0001] The utility model relates to the field of distiller cold core equipment, in particular to a micro molecular distiller cold core structure. Background Art
[0002] A micromolecular distiller is a laboratory-scale distillation device that uses the principle that molecules have different volatilities at different temperatures to separate and purify substances through a heating and condensation process. This device is particularly suitable for the separation of heat-sensitive substances because it can operate at lower temperatures, thereby reducing the risk of thermal decomposition.
[0003] At present, the micromolecular distiller will quickly condense the evaporated steam into liquid through the cold core structure. When the existing micromolecular distiller cold core structure is in use, it is first connected to the threaded ferrule joint through the refrigerant inlet and the refrigerant return port through the set threaded connection port, and the steam flows into the refrigerant outer sleeve, and the steam is divided by the refrigerant partition. However, when the existing micromolecular distiller cold core structure is in use, the refrigerant outer sleeve is connected to the connecting pipe through threads. The threaded connection may become loose when used for a long time or subjected to external force, which will not only affect the stability of the connection, but also may cause the gap between the refrigerant outer sleeve and the connecting pipe to increase. In addition, when the cold core structure needs to be frequently replaced or maintained, this may increase the difficulty and cost of operation.
[0004] Therefore, it is necessary to provide a new micromolecular distiller cold core structure to solve the above-mentioned technical problems. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a cold core structure of a micro molecular distiller.
[0006] The utility model provides a micro molecular distiller cold core structure comprising a flange, a connecting pipe is fixedly connected to the top of the flange, a connecting component is movably connected to the inner wall of a groove opened on the top of the connecting pipe, and a refrigerant outer sleeve is fixedly connected to the top of the connecting component;
[0007] The connecting component includes a movable ring, which is fixedly connected to the bottom of the refrigerant outer sleeve, and one end of the movable ring away from the refrigerant outer sleeve is movably connected to the inner wall of the groove opened at the top of the connecting pipe, the inner wall of the groove opened on the side wall of the movable ring is movably connected to a limiting block, the end of the limiting block away from the movable ring is fixedly connected with a compression spring, the end of the compression spring away from the limiting block is fixedly connected to the inner wall of the connecting pipe, and the inner wall of the connecting pipe is movably connected with two locking components.
[0008] Preferably, the locking assembly includes a return spring and a locking block, one end of the return spring is fixedly connected to the inner wall of the groove opened in the connecting pipe, and the end of the return spring away from the connecting pipe is fixedly connected to a slider, the locking block is fixedly connected to the top of the slider, and the locking block is movably connected to the inner wall of the groove opened in the refrigerant outer sleeve.
[0009] Preferably, a refrigerant partition is provided on the inner wall of the groove opened at the top of the connecting pipe, and the refrigerant partition is interference fit between the refrigerant outer casing.
[0010] Preferably, a refrigerant inlet and a refrigerant return are respectively provided on the flange, and threaded connection ports are provided at the refrigerant inlet and the refrigerant return.
[0011] Preferably, a water outlet pipe is fixedly connected to the bottom of the flange, and the water outlet pipe, the refrigerant inlet and the refrigerant return port are all integrally formed with the flange.
[0012] Preferably, a sealing gasket is provided between the refrigerant outer sleeve and the connecting pipe.
[0013] Compared with the related art, the micro molecular distiller cold core structure provided by the utility model has the following beneficial effects:
[0014] Through the provided connecting assembly, when the refrigerant outer sleeve needs to be replaced, the movable ring is first pulled toward the end away from the connecting pipe. At this time, the movable ring will squeeze the limit block and the compression spring, so that the movable ring leaves the groove provided on the connecting pipe. Since the locking assembly loses the limit of the movable ring on itself, it leaves the groove provided on the refrigerant outer sleeve under the action of the locking assembly, thereby taking out the refrigerant outer sleeve that needs to be replaced, and then the new refrigerant outer sleeve is re-inserted into the groove provided on the connecting pipe through the movable ring. At the same time, the locking assembly in the connecting pipe is squeezed to make it inserted into the groove provided on the refrigerant outer sleeve, thereby realizing the replacement of the refrigerant outer sleeve. This device reduces the impact on the connection stability, reduces the probability of an increase in the gap between the refrigerant outer sleeve and the connecting pipe, and reduces the probability of increased operating difficulty and cost when the cold core structure needs to be frequently replaced or maintained.
