Description

Technical Field

[0001] This utility model relates to a flask, and more particularly to a round-bottom flask suitable for solvent extraction of solid floating materials by heating. Background Technology

[0002] In solvent extraction experiments, single-necked or multi-necked round-bottom flasks are typically used as the experimental containers. The raw material to be extracted and the solvent are added to the round-bottom flask, and extraction is carried out by heating in a water bath or oil bath. When the density of the solid raw material to be extracted is lower than that of the solvent, the raw material will float on the surface of the solvent and cannot be completely immersed in the solvent, affecting the extraction effect and making it impossible to accurately calculate the optimal solid-liquid ratio.

[0003] After a certain extraction time, when taking a certain amount of extract from the round-bottom flask, the connected condenser and other instruments must be removed before the operation can be carried out. This is cumbersome, and the solid raw material is prone to clogging the pipette when aspirating the sample, making the operation inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a round-bottom flask suitable for solvent extraction of solid floating materials by heating, in order to solve the technical problems in the prior art. It can improve the extraction efficiency and experimental accuracy of solid floating material raw materials, and facilitate sampling.

[0005] This utility model provides a round-bottom flask suitable for solvent extraction of solid floating materials by heating, including a flask body, a flask cap installed at the mouth end of the flask body, the flask cap having a first mounting hole, a second mounting hole and a liquid extraction hole, a condenser installed in the first mounting hole and a pressing component installed in the second mounting hole.

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] Embodiments of this utility model: such as Figure 1 and Figure 2 As shown, a round-bottom flask suitable for solvent extraction of solid floating materials by heating includes a flask body 1, a flask cap 2 installed at the mouth end of the flask body 1, and a first mounting hole 3, a second mounting hole 4 and a liquid dispensing hole 5 opened on the flask cap 2. A condenser tube 6 is installed on the first mounting hole 3 and a pressing component is installed on the second mounting hole 4.

[0017] The condenser tube 6 of this invention does not need to be disassembled after use and can be directly extracted through the liquid extraction hole 5. With the setting of the pressing component, solid raw materials with a density lower than that of the solvent can be completely pressed into the solvent, thereby improving the extraction efficiency and experimental accuracy of solid raw materials.

[0018] Specifically, the main body of the flask body 1 is a cylindrical tube, the bottom of the flask body 1 is hemispherical, and the mouth of the flask body 1 is a conical part that is larger at the top and smaller at the bottom.

[0019] The flask body 1 is made of transparent glass, and the inner wall of the mouth end of the flask body 1 has a frosted surface. The cap 2 is made of rubber. By designing the mouth into a conical shape that is wider at the top and narrower at the bottom, it is easy to install and remove the cap 2.

[0020] The bottle cap 2 is made of rubber, which effectively seals the bottle opening and ensures the airtightness of the connection between the condenser tube 6 and the first mounting hole 3, as well as the airtightness of the connection between the pressure assembly and the second mounting hole 4. The condenser tube 6 is an existing product and can be purchased directly.

[0021] Furthermore, the pressing assembly includes a height adjusting rod 7 and a pressing plate 8. The pressing plate 8 is a circular plate with a diameter slightly smaller than the inner diameter of the flask body 1. The diameter of the height adjusting rod 7 is larger than the diameter of the second mounting hole 4. The lower end of the height adjusting rod 7 is fixedly connected to the pressing plate 8. Several first through holes 9 are provided on the pressing plate 8.

[0022] Because the diameter of the height adjustment rod 7 is larger than the diameter of the second mounting hole 4, the bottle cap 2 can clamp the height adjustment rod 7, and it will not slide down automatically after the height of the height adjustment rod 7 is manually adjusted.

[0023] A liquid-collecting cylinder 10 is fixed on the top surface of the pressure plate 8. The top of the liquid-collecting cylinder 10 is an open structure. Several second through holes 11 are opened on the cylinder wall of the liquid-collecting cylinder 10. The diameter of the second through holes 11 is smaller than the diameter of the first through hole 9. The liquid-collecting cylinder 10 is located below the liquid-collecting hole 5.

[0024] By setting up the liquid collection cylinder 10, large particles can be prevented from entering the pipette during liquid collection. The second through hole 11 has a small diameter, which can be set to 0.5mm-1mm, to prevent larger particles from entering the liquid collection cylinder 10.

[0025] Furthermore, a plug 12 is inserted into the liquid extraction hole 5, and a pull ring 13 is fixed to the top of the plug 12.

[0026] The working principle of this utility model is as follows: The raw material to be extracted and the solvent are added into the flask body 1, and then the flask cap 2 is closed. The height of the pressing plate 8 is adjusted by the height adjustment rod 7 so that the pressing plate 8 completely presses the raw material into the solvent, and the liquid level of the solvent is below the top surface of the liquid collection cylinder 10. Then, heating extraction is performed. When sampling is required, the stopper 12 is removed by the pull ring 13, and a pipette is inserted into the flask body 1 through the liquid collection hole 5. The end of the pipette is inserted into the liquid collection cylinder 10 to draw liquid. After sampling is completed, the stopper 12 is closed tightly.

[0027] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
