Description

Technical Field

[0001] This utility model relates to the field of chemical reactor vessel technology, and in particular to a constant temperature heating reaction flask. Background Technology

[0002] Reaction flasks are an important type of reactor vessel in chemical synthesis reactions. Usually, when heating or maintaining a constant temperature is required during the reaction, it can be done by using a water (bath) or an electric heating mantle. When the reaction is at a low temperature, an ice-water (salt water) bath is required. When it is necessary to stop heating or cooling during the reaction, the heating or cooling equipment needs to be moved repeatedly. Moving heating or cooling equipment is troublesome, time-consuming, and labor-intensive.

[0003] The currently disclosed constant-temperature reaction flask (CN203140003U) specifically relates to a constant-temperature reaction flask with a built-in glass coil, belonging to the field of chemical synthesis preparation vessel technology. It consists of a reaction flask body and a glass coil, replacing the conventional round bottom of a reaction flask with a flat bottom. The glass coil is housed within the reaction flask body, with an inlet at the bottom and an outlet at the top. This invention simplifies the constant-temperature operation procedure of the reaction process, ensuring that the reactants within the reaction flask body are always under heating, cooling, and constant temperature during the reaction, thus ensuring the smooth progress of the chemical reaction. However, during use, the built-in glass coil, located inside the constant-temperature reaction flask, can easily interfere with the reaction process. Furthermore, it relies on the temperature of the water circulating through the glass coil to maintain the constant temperature of the reaction flask. This results in uneven temperature distribution within the reaction flask, with a higher temperature at the inlet and a lower temperature at the outlet during water circulation.

[0004] Therefore, it is necessary to provide a new isothermal heating reaction flask to solve the above-mentioned technical problems. Utility Model Content

A temperature control tube is installed in the middle of the outer bottle body. A recessed part that engages with the temperature control tube is integrally formed in the middle of the inner bottle body. An inner glass coil is provided inside the temperature control tube. An outer glass coil is provided in the inner cavity of the outer bottle body. The liquid outlet end of the outer glass coil is connected to the liquid inlet end of the inner glass coil. A heating component is installed inside the temperature control tube.

[0007] Preferably, the liquid inlet of the outer glass coil extends from the upper part of the outer bottle shell.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 3 This utility model provides a constant temperature heating reaction flask, which includes:

[0021] The outer bottle 1 and the inner bottle 2 inserted into the outer bottle 1 are provided. A temperature control tube 3 is installed in the middle of the outer bottle 1. A recessed part 21 that engages with the temperature control tube 3 is integrally formed in the middle of the inner bottle 2. An inner glass coil 4 is provided inside the temperature control tube 3. An outer glass coil 5 is provided in the inner cavity of the outer bottle 1. The liquid outlet end of the outer glass coil 5 is connected to the liquid inlet end of the inner glass coil 4. A heating component 6 is installed inside the temperature control tube 3.

[0022] The liquid inlet 51 of the outer glass coil 5 extends from the upper part of the outer bottle body 1. The liquid outlet 41 of the inner glass coil 4 extends from the bottom end of the temperature control tube 3.

[0023] It should be noted that during use, the inlet 51 and outlet 41 are connected to the water temperature bath (constant temperature) device to establish water temperature circulation using a circulation pump. Then, the constant temperature water flows from the inlet 51 through the outer glass coil 5 and the inner glass coil 4 to control the temperature of the inner bottle 2. This is done by circulating warm water to ensure that the inner bottle 2 maintains a constant temperature. During the circulation process, the heating component 6 is used to further control and heat the water, compensating for the temperature loss during the water circulation, thereby maintaining a stable constant temperature.

[0024] In this embodiment: a groove is provided at the top of the inner cavity of the outer bottle 1, a sealing ring is embedded in the groove, and a heat-conducting medium is filled between the outer bottle 1 and the inner bottle 2. In this way, when the outer glass coil 5 is used for temperature control and heat conduction, the heat-conducting medium is in full contact with the outer glass coil 5 and then conducts heat with the inner bottle 2, thereby maintaining the temperature of the inner bottle 2.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 3 The heating assembly 6 includes a sealing end cap 61, which is installed at the bottom end of the temperature control tube 3. A constant temperature heating rod 62 is embedded in the sealing end cap 61. The constant temperature heating rod 62 is inserted into the temperature control tube 3, which is filled with ceramic particle medium. The constant temperature heating rod 62 is electrically connected to a temperature controller 63, which is embedded in the outer wall of the outer bottle 1.

[0026] It should be noted that when the heating component 6 is in use, the temperature of the bottle is monitored by the temperature controller 63. When the temperature is kept constant by water bath circulation, when the temperature is lower than the set temperature, the constant temperature heating rod 62 is activated to heat the middle part of the inner bottle 2, so as to further maintain the constant temperature of the bottle.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 3 The temperature control tube 3 has an external thread on one side of its bottom end, and the recessed part 21 has an internal thread that mates with the external thread at its bottom end.

[0028] It should be noted that the inner bottle 2 is connected to the temperature control tube 3 by the recessed part 21, which facilitates disassembly and cleaning later.

[0029] The working principle of the constant temperature heating reaction flask provided by this utility model is as follows:

[0030] The inlet 51 and outlet 41 are connected to the water bath (constant temperature) device using a circulating pump to establish a water temperature circulation. Then, the constant temperature water flows from the inlet 51 through the outer glass coil 5 and the inner glass coil 4 to control the temperature of the inner bottle 2. The circulation of warm water ensures that the inner bottle 2 maintains a constant temperature. During the circulation process, the temperature of the bottle is monitored by the temperature controller 63. When the temperature is lower than the set temperature while maintaining a constant temperature using the water bath circulation, the constant temperature heating rod 62 is activated to heat the middle part of the inner bottle 2, further maintaining the constant temperature of the bottle.

[0031] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
