Abstract
Description
Technical Field
[0001] The utility model relates to an experimental device, in particular to a support for distillation experiments. Background Art
[0002] Distillation is an experimental method for separating the components of a liquid mixture. The liquid mixture is heated to boil, producing vapor, and then the vapor is condensed to turn it back into a liquid. Since the boiling points of different components are different, the ratio of components in the vapor and condensate will also change, thus achieving separation. Distillation is often used to separate volatile components in a liquid mixture, such as separating a mixture of alcohol and water.
[0003] The existing stands for small and medium-sized distillation experiments require an alcohol lamp to be lit during the experiment. Although the alcohol lamp is difficult to be blown out by outdoor wind or airflow generated by people walking, the stability of the alcohol lamp flame determines the effect of the distillation experiment during the long-term heating distillation experiment. The stable and concentrated alcohol lamp flame provides continuous heat energy, which can ensure the orderly progress of the experiment.
[0004] The device provides a support for distillation experiments which is provided with a windproof cover, thereby ensuring a stable, continuous and concentrated flame of an alcohol lamp. Utility Model Content
[0005] In order to overcome the disadvantage that the existing experimental alcohol lamp is not provided with a windproof cover, the alcohol lamp cannot provide a stable and concentrated flame in the distillation experiment, resulting in unsatisfactory distillation experiment effect, the utility model provides a bracket for distillation experiment provided with a windproof cover.
[0006] A bracket for distillation experiments includes a mounting frame, a base, a fixed block, a support plate, a limit rod, a connecting block, a wind shield and an adjusting screw. The mounting frame is fixedly connected to one side of the base, and the fixed block is fixedly connected to the other side of the base. The adjusting screw is rotatably connected in the fixed block. The base is fixedly connected to the limit rod. The support plate is slidably connected to the limit rod. The support plate is provided with a wind shield. The side of the support plate is fixedly connected to the connecting block. The connecting block is mounted on the adjusting screw through a threaded sleeve. The adjusting screw is rotated to drive the support plate to move upward through the connecting block, and the support plate pushes the wind shield to move upward.
[0007] Furthermore, it also includes a movable plate, a slide rail and a baffle plate. The inner side of the support plate is provided with a slide rail, the movable plate is slidably connected in the slide rail, and the baffle plate is connected to one side of the movable plate.
[0008] Furthermore, the baffle plate and the wind shield can form an annular closed space.
[0009] Furthermore, a handle is included, and the handle is connected to the side of the baffle.
[0010] Furthermore, it also includes an auxiliary roller, which is connected to the side of the base through a bracket, and the auxiliary roller can contact the movable plate and support it.
