Description

Technical Field

[0001] This utility model relates to the field of chemical reaction vessel technology, and in particular to a reaction flask with a cooling structure. Background Technology

[0002] A reaction flask is a container used to carry out physical and chemical reactions in a medium. It is generally used in laboratory settings and is usually made of hard glass. The most common types are conical flasks, round-bottom flasks, and flat-bottom flasks.

[0003] In chemical experiments, reaction flasks are often heated, and after the reaction is completed, they are usually cooled by natural cooling or water bath cooling. However, some experiments require faster cooling rates to form crystals of different forms. Existing reaction flasks lack designs for rapid cooling of the solvent inside the flask. Therefore, we propose a reaction flask with a cooling structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a reaction flask with a cooling structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reaction flask with a cooling structure includes a reaction flask body, and a cooling component is disposed inside the reaction flask body;

[0007] The cooling assembly includes a heat exchange tube, with an inlet and an outlet at the upper end of the heat exchange tube. A connecting sleeve is provided on both the inlet and the outlet. A symmetrically arranged horizontal tube is connected to the upper side wall of the reaction flask body. A connecting tube is inserted into the horizontal tube and is inserted into the connecting sleeve. A protective sleeve structure is placed on the upper end of the reaction flask body.

[0008] Preferably, the protective sleeve structure includes an outer ring, an inner sleeve is fixedly connected to the surface of the outer ring, a clamping rod is slidably connected inside the inner sleeve, and a protrusion is fixedly connected to the lower end of the clamping rod.

[0009] Preferably, the heat exchange tube is spiral-shaped and made of glass.

[0010] Preferably, a clamping block is fixedly connected to the lower surface of the outer ring, and a slot is provided at the lower end of the clamping block, which is engaged with the horizontal tube.

[0011] Preferably, the inner wall of the inner sleeve is provided with a rubber ring, and the rubber ring is abutted against the clamping rod.

[0012] Preferably, the ends of the horizontal tubes that are close to each other are provided with a tapered opening, and the connecting sleeve is located inside the tapered opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up a cooling component and utilizing heat exchange tubes, can more efficiently cool the solution in the reaction flask. At the same time, this design facilitates the disassembly and cleaning of the heat exchange tubes. By setting up a protective sleeve structure, the heat exchange tubes will not collide with the inner wall of the reaction flask body during insertion and removal, thus preventing damage to the reaction flask body or the heat exchange tubes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A reaction flask with a cooling structure includes a reaction flask body 1, wherein a cooling assembly is provided inside the reaction flask body 1;

[0023] The reaction flask body 1 is one of conical flask, round-bottom flask or flat-bottom flask, and the capacity of the reaction flask body 1 is more than 1000ml. Smaller reaction flasks do not require an internal cooling structure.

[0024] The cooling assembly includes a heat exchange tube 2, with an inlet 3 and an outlet 4 at the upper end of the heat exchange tube 2. A connecting sleeve 5 is provided on both the inlet 3 and the outlet 4. A symmetrically arranged horizontal tube 6 is connected to the upper side wall of the reaction bottle body 1. A connecting tube 7 is inserted into the horizontal tube 6 and inserted into the connecting sleeve 5. A protective sleeve structure is placed on the upper end of the reaction bottle body 1.

[0025] In this design, the main body of the heat exchange tube 2 is located in the reaction flask body 1. During use, the connecting tube 7 is inserted into the inlet 3 and outlet 4 along the horizontal tube 6, and the connecting sleeve 5 is used to ensure the seal between the connecting tube 7 and the heat exchange tube 2. When rapid cooling is required, the connecting tube 7 is connected to the cold water supply line and the recovery line, so that the cold water exchanges heat with the solution in the reaction flask body 1 through the heat exchange tube 2. In addition, the experimenter can simultaneously perform water bath cooling operation outside the reaction flask body 1. Furthermore, the end of the connecting sleeve 5 is inserted into the horizontal tube 6, so that the heat exchange tube 2 will remain in the same position after the connecting tube 7 is pulled out, and will not fall downwards, making it convenient for the user to clean the reaction flask body 1 and the heat exchange tube 2 after use.

[0026] It should be noted that the protective sleeve structure is mainly used to protect the heat exchange tube 2 when it is inserted into the reaction vessel body 1, and to facilitate the user to remove the heat exchange tube 2 from the reaction vessel body 1 after use. When a higher sealing requirement is required, the protective sleeve structure can also be removed.

[0027] Furthermore, the protective sleeve structure includes an outer ring 8, an inner sleeve 9 is fixedly connected to the surface of the outer ring 8, a clamping rod 10 is slidably connected inside the inner sleeve 9, and a protrusion 11 is fixedly connected to the lower end of the clamping rod 10.

[0028] In this design, the outer diameter of the outer ring 8 is larger than the upper port diameter of the reaction flask body 1, the inner sleeve 9 is inserted into the flask mouth, and the clamping rod 10 limits the heat exchange tube 2. When the heat exchange tube 2 is inserted into the reaction flask body 1, the clamping rod 10 abuts against the heat exchange tube 2 to prevent the heat exchange tube 2 from colliding with the inner wall of the reaction flask body 1 when it is inserted.

[0029] Furthermore, the heat exchange tube 2 is spiral-shaped and made of glass. A clamping block 12 is also fixedly connected to the lower surface of the outer ring 8. The lower end of the clamping block 12 has a slot, which engages with the horizontal tube 6.

[0030] The clamping block 12 is designed to engage with the spiral heat exchange tube 2. When inserting the heat exchange tube 2, the heat exchange tube 2 can be rotated first, causing it to move downwards along the clamping block 12. The straight part of the heat exchange tube 2 abuts against the protrusion 11. Then, the slide bar and the heat exchange tube 2 continue to slide downwards until the connecting sleeve 5 is engaged with the horizontal tube 6, completing the installation of the heat exchange tube 2. The clamping block 12, along with the slot, is used to position the protective sleeve structure, ensuring that after the heat exchange tube 2 is inserted into the reaction bottle body 1, the inlet 3 and outlet 4 are aligned with the opening of the horizontal tube 6.

[0031] Furthermore, the inner wall of the inner sleeve 9 is provided with a rubber ring 13, and the rubber ring 13 is abutted against the clamping rod 10. The rubber ring 13 is provided to increase the friction between the clamping rod 10 and the inner sleeve 9, ensuring that the heat exchange tube 2 can be screwed down first, and then the heat exchange tube 2 can be slid down.

[0032] Furthermore, the ends of the horizontal tubes 6 that are close to each other are provided with a tapered opening, and the connecting sleeve 5 is located inside the tapered opening;

[0033] The conical opening is used to guide the connecting sleeve 5 to be better inserted into the horizontal tube 6. After the splicing is completed, the connecting tube 7 supports the connecting sleeve 5 from the inside of the connecting sleeve 5. The inner wall of the connecting sleeve 5 is press-fitted with the connecting tube 7 and the outer wall of the connecting sleeve 5 is press-fitted with the inner wall of the horizontal tube 6 to ensure the sealing effect at this point and prevent cooling water from seeping into the reaction bottle body 1.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
