Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laboratory equipment and relates to an overflow-proof distillation flask used in the distillation process. Background Technology
[0002] Distillation is a common separation technique widely used in industries such as chemicals, pharmaceuticals, and food processing. During distillation, a liquid is heated to boiling point, producing steam, which is then cooled by a condenser and converted back into a liquid, thus separating components with different boiling points.
[0003] Existing distillation flask designs typically include a round-bottomed or pear-shaped body to hold the liquid to be distilled. The neck is usually connected to a side arm for connecting to a condenser. During distillation, the liquid is heated to boiling, and the resulting vapor enters the condenser through the side arm. However, existing distillation flasks have some shortcomings during distillation, especially when processing complex water or soil samples. Often, many bubbles or light impurities overflow, which not only affects distillation efficiency but may also lead to inaccurate experimental results. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide an anti-overflow distillation flask, which effectively prevents overflow during the distillation process by setting an anti-overflow component and a pressure balancing component at the neck.
[0005] Through long-term exploration and experimentation, as well as numerous trials and efforts, the inventors have continuously reformed and innovated to solve the above-mentioned technical problems. The technical solution provided by this utility model is to provide an anti-overflow distillation flask, including a bottle body, a bottle neck, and a branch tube. The top of the bottle neck is the bottle mouth, and a bottle stopper is inserted into the bottle mouth. A connecting post is provided above the bottle stopper, and an anti-overflow component is provided below it. A pressure regulating hole is provided on the bottle stopper and the connecting post, and a pressure balancing component is detachably connected to the connecting post. The anti-overflow component extends from the bottle neck to the bottle body.
[0006] According to one embodiment of the anti-overflow distillation flask of this utility model, the bottom of the distillation flask is flat.
[0007] According to one embodiment of the anti-overflow distillation flask of this utility model, the pressure balancing assembly includes an elastic air bladder.
[0008] According to one embodiment of the anti-overflow distillation flask of this utility model, the diameter of the pressure regulating hole is 1-3 mm.
[0009] According to one embodiment of the anti-overflow distillation flask of this utility model, the anti-overflow component includes a connecting plate and an inverted funnel, with the larger opening of the inverted funnel at the bottom and the smaller opening at the top.
[0010] According to one embodiment of the anti-overflow distillation flask of this utility model, there are two connecting plates, and the gap between the connecting plates is larger than the inlet diameter of the branch pipe.
[0011] According to one embodiment of the anti-overflow distillation flask of this utility model, the number of inverted funnels is 2 to 4, which are equidistantly arranged below the branch pipe inlet.
[0012] According to one embodiment of the anti-overflow distillation flask of this utility model, the surface of the inverted funnel is provided with a hydrophilic coating.
[0013] According to one embodiment of the anti-overflow distillation flask of this utility model, the lower middle part of the flask body is cylindrical, and the upper part of the flask body smoothly transitions to the neck; the inner diameter of the flask body is 4 to 6 times the inner diameter of the neck, and the inner diameter of the branch tube is 60% to 90% of the inner diameter of the neck.
[0014] According to one embodiment of the anti-overflow distillation flask of this utility model, the flask body and the neck are integrally formed or detachably sealed.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention relates to an anti-overflow distillation flask, which significantly reduces the risk of liquid spillage during distillation by integrating an anti-overflow component at the neck. The inverted funnel design within the anti-overflow component effectively captures and guides foam backflow, reducing spillage.
[0017] The flat-bottom design of the distillation flask enhances its stability on the electric furnace, resulting in a more uniform heat distribution and thus improving distillation efficiency.
[0018] The pressure bladder in the pressure balancing assembly provides excellent pressure regulation for the distillation flask. The bladder automatically expands and contracts according to changes in internal pressure, maintaining pressure balance between the inside and outside of the flask, further preventing overflow and protecting the flask from damage due to excessive pressure. The pressure regulating port allows researchers to adjust the internal pressure according to experimental needs, ensuring the safety of the distillation process.
[0019] The hydrophilic coating on the surface of the inverted funnel helps to capture foam more effectively and reduce the amount of impurities entering the distillate, thereby improving the purity of the distillate.
[0020] The lower part of the distillation flask features a cylindrical design, which, combined with the smooth transition to the neck, enhances the overall structural stability.
[0021] The one-piece molded or detachable seal connection between the bottle body and neck provides flexible installation and maintenance options. Attached Figure Description

[0041] The following description, in conjunction with the accompanying drawings and a specific embodiment, will be provided.
[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
[0044] See Figures 1 to 5 This embodiment describes an overflow-proof distillation flask with a body 110 and a flat bottom 111 to enhance stability on an electric furnace. The lower middle part of the body 110 is cylindrical, which helps to distribute heat evenly during distillation. The neck 120 smoothly transitions from the body 110, and its top is the mouth 121 for installing the stopper 200. The inner diameter of the body 110 is 4 to 6 times the inner diameter of the neck 120, while the inner diameter of the branch pipe 122 is 60% to 90% of the inner diameter of the neck 120. This proportional relationship facilitates smooth steam flow.
[0045] The body 110 and neck 120 can be integrally formed or connected by a detachable seal. An integrally formed design provides structural integrity and stability, while a detachable seal offers ease of installation and maintenance. In a detachable connection, the body 110 and neck 120 are sealed together by a sealing ring or gasket, ensuring no liquid leakage during distillation. The body 110 and neck 120 are made of borosilicate glass, a material with good heat resistance, chemical stability, and light transmittance, commonly used for distillation flasks. In some embodiments, quartz glass may also be used, offering superior high-temperature resistance and suitability for high-temperature distillation processes.
[0046] A stopper 200 is inserted into the bottle neck 120 at the top of the bottle opening 121. A connecting post 210 is provided above the stopper 200 for fixing the pressure balancing assembly 300 and for facilitating the insertion / removal of the stopper 200. Pressure adjustment holes 220 with a diameter of 1 to 3 mm are provided on the stopper 200 and the connecting post 210, allowing researchers to adjust the internal pressure according to experimental needs. The pressure balancing assembly 300 is detachably connected to the connecting post 210. This assembly includes a flexible air bladder that automatically adjusts according to changes in internal pressure to maintain stable pressure. The air bladder is made of flexible silicone, a material with excellent elasticity and chemical resistance.
[0047] The anti-overflow assembly 230, located below the stopper 200 and extending from the neck 120 to the body 110, includes two connecting plates 231 and two to four inverted funnels 232. The gap between the connecting plates 231 is larger than the inlet diameter of the branch pipe 122, a design that facilitates smooth steam passage. The inverted funnels 232, with their larger openings at the bottom and smaller openings at the top, are equidistantly positioned below the inlet of the branch pipe 122. Their surfaces are coated with a hydrophilic coating to help capture and guide foam backflow, preventing overflow. The hydrophilic coating uses hydrophilic polymers such as povidone (PVP), polyacrylamide (PAM), or polyethylene glycol (PEG). These materials can form a stable hydrophilic cross-linked film, utilizing the hydrophilic groups in their molecules to absorb a large amount of water to form a hydrated layer, giving the coating hydrophilicity and super-lubricity. Of course, when selecting a specific water coating based on existing technology, it is also necessary to consider whether the coating itself will adversely affect the distillation results.
[0048] When using the overflow-proof distillation flask of this embodiment, the experimenter can adjust the internal pressure of the flask through the pressure regulating port 220 as needed to adapt to different distillation conditions. During distillation, the overflow-proof component 230 effectively prevents liquid from overflowing, while the pressure balancing component 300 ensures the stability of the internal pressure. After distillation, the experimenter can remove the stopper 200 and the overflow-proof component 230 for cleaning. Due to the detachable design of the overflow-proof component 230, cleaning and maintenance become simple and quick.
