[0024] As Figure 1As shown in the figure, a reaction kettle device for laboratory small-scale tests includes a reaction kettle 1, a heating medium tank 2, and a cooling medium tank 3; a temperature-changing jacket 10 is provided outside the reaction kettle 1, and a temperature-changing medium inlet 11 and a temperature-changing medium outlet 12 are provided on the temperature-changing jacket 10; a heating medium supply path 21 communicating with the temperature-changing medium inlet 11 and a heating medium return path 22 communicating with the temperature-changing medium outlet 12 are provided on the heating medium tank 2. A heating medium supply valve 23 is provided on the heating medium supply path 21 near the temperature-changing medium inlet 11 side, and a heating medium supply pump 27 is provided near the heating medium tank 2 side. A heating medium return valve 24 is provided on the heating medium return path 22 near the heating medium tank 2 side. A heating medium circulation path 25 is provided between the heating medium supply path 21 and the heating medium tank 2. The heating medium circulation path 25 communicates between the heating medium supply valve 23 and the heating medium supply pump 27, and a heating medium circulation valve 26 is provided on the heating medium circulation path 25; a cooling medium supply path 31 communicating with the temperature-changing medium inlet 11 and a cooling medium return path 32 communicating with the temperature-changing medium outlet 12 are provided on the cooling medium tank 3. A cooling medium supply valve 33 is provided on the cooling medium supply path 31 near the temperature-changing medium inlet 11 side, and a cooling medium supply pump 37 is provided near the cooling medium tank 3 side. A cooling medium return valve 34 is provided on the cooling medium return path 32 near the cooling medium tank 3 side. A cooling medium circulation path 35 is provided between the cooling medium supply path 31 and the cooling medium tank 3. The cooling medium circulation path 35 communicates between the cooling medium supply valve 33 and the cooling medium supply pump 37, and a cooling medium circulation valve 36 is provided on the cooling medium circulation path 35. Compared with the existing technology which has a single tank with heating and cooling functions, for example, after a reaction at 60°C and then cooling to 0°C for crystallization, it is necessary to first heat the heat transfer medium to 60°C with a heating module, turn off the heating module after the reaction is completed, and then turn on the cooling module. The heating medium needs to be cooled from 60°C to 0°C. In this application, the cooling module and the heating module are integrated in the reaction kettle device, and at the same time, the cooling medium tank and the heating medium tank are separately arranged. When heating is required, the heating tank is opened, and when cooling is required, the cooling tank is opened. At the same time, it can be quickly switched to realize the rapid cooling and heating of the reaction liquid in the reaction kettle, saving the process of cooling the heat transfer medium from 60°C to 0°C. This application does not use external heating and cooling equipment, occupies a small area, separates the heating tank and the cooling tank to realize heating and cooling, can save time, and at the same time protects the product.
[0025] The present application provides a reaction kettle device for laboratory scale experiments. The cooling module and the heating module are integrated in the reaction kettle device, and at the same time, the cooling medium tank and the heating medium tank are separately arranged. The heating medium tank and the cooling medium tank can be controlled to the required temperature simultaneously, and the heating medium or the cooling medium can be quickly switched to the temperature-changing jacket in a flowing manner, so as to realize the rapid heating and rapid cooling of the reaction kettle. In addition, a heating medium circulation path is provided to preheat the heating medium supply path to a specified temperature, and similarly, a cooling medium circulation path can pre-cool the cooling medium supply path to a specified temperature, saving time and protecting the product at the same time.
[0026] Further, when the heating medium supply valve 23 is closed and the heating medium circulation valve 26 is opened, the heating medium in the heating medium tank 2 can be circulated back to the heating medium tank 2 through the heating medium supply path 21 and the heating medium circulation path 25 in sequence by the heating medium supply pump 27 to form an internal circulation of the heating medium. When the heating medium supply valve 23 is opened, the heating medium circulation valve 26 is closed, the cooling medium supply valve 33 is closed, the cooling medium circulation valve 36 is closed, and the heating medium return valve 24 is opened, the heating medium in the heating medium tank 2 can enter the temperature-changing jacket 10 from the temperature-changing medium inlet 11 through the heating medium supply path 21 in sequence by the heating medium supply pump 27, and return to the heating medium tank 2 through the heating medium return path 22 from the temperature-changing medium outlet 12 to form an external circulation of the heating medium. The heating medium tank of the present application has two modes of internal circulation and external circulation, and can be switched with one key. The internal circulation means that the medium in the heating medium tank does not circulate through the jacket of the reaction kettle, and the external circulation means that the medium in the heating medium tank circulates through the jacket of the reaction kettle. The purpose of the internal circulation is to preheat the medium in the heating medium tank and the heating medium supply path to a certain temperature to prepare for the external circulation and the temperature rise in the reaction kettle.
[0027] Furthermore, both the heating medium circulation path 25 and the heating medium return path 22 are connected to the upper side of the heating medium tank 2, and the heating medium supply path 21 is connected to the lower side of the heating medium tank 2. This design is beneficial to output the heating medium at a specified temperature.
[0028] Further, when the cooling medium supply valve 33 is closed and the cooling medium circulation valve 36 is opened, the cooling medium in the cooling medium tank 3 can be returned to the cooling medium tank 3 in sequence through the cooling medium supply path 31 and the cooling medium circulation path 35 by the cooling medium supply pump 37 to form an internal circulation of the cooling medium. When the cooling medium supply valve 33 is opened, the cooling medium circulation valve 36 is closed, the heating medium supply valve 23 is closed, the heating medium circulation valve 26 is closed, and the cooling medium return valve 34 is opened, the cooling medium in the cooling medium tank 3 can be passed through the cooling medium supply path 31 into the heat exchange jacket 10 from the heat exchange medium inlet 11 and returned to the cooling medium tank 3 through the cooling medium return path 32 from the heat exchange medium outlet 12 by the cooling medium supply pump 37 to form an external circulation of the cooling medium. The cooling tank medium of the present application also has two modes of internal circulation and external circulation, and can also be switched with one key. The internal circulation is that the medium of the cooling tank does not circulate through the jacket of the reaction kettle, and the external circulation is that the cooling tank medium circulates through the jacket of the reaction kettle. The purpose of the internal circulation is to pre-cool the medium in the cooling medium tank and the cooling medium supply path to a certain temperature to prepare for the external circulation and the cooling in the reaction kettle.
[0029] Further, both the cooling medium circulation path 35 and the cooling medium return path 32 communicate with the upper side of the cooling medium tank 3, and the cooling medium supply path 31 communicates with the lower side of the cooling medium tank 3. This design can facilitate the output of the cooling medium at a specified temperature.
[0030] It should be understood that the internal circulation of the heating medium tank and the internal circulation of the cooling medium tank can be opened simultaneously. The external circulation of the heating medium tank and the external circulation of the cooling medium tank cannot be opened simultaneously (only one can be opened). At the same time, the internal circulation and the external circulation of the heating medium tank cannot be opened simultaneously, and the internal circulation and the external circulation of the cooling medium tank cannot be opened simultaneously.
[0031] Preferably, the medium in the heating medium tank and the medium in the cooling medium tank are the same medium. Silicone oil, water, antifreeze, etc. are selected according to the use temperature. For example, silicone oil is selected for large temperature differences, and water is selected for small temperature differences and above 0°C. However, the heating medium tank and the cooling medium tank must be the same medium.
[0032] Preferably, the heating medium tank 2 is heated by electric heating, and the cooling medium tank 3 is refrigerated by a refrigeration compressor. This technology integrates the cooling module and the heating module in the reaction kettle equipment, and at the same time separates the cooling medium tank and the heating medium tank (the prior art is a single tank with heating and cooling functions. For example, after a reaction at 60°C and then cooling to 0°C for crystallization, the heat transfer medium needs to be heated to 60°C by the heating module first. After the reaction is completed, the heating module is turned off, and the cooling module is turned on. The heating medium is cooled from 60°C to 0°C). When heating is required, the heating tank is turned on, and when cooling is required, the cooling tank is turned on. At the same time, rapid switching can be achieved, enabling the reaction liquid in the reaction kettle to be rapidly cooled and heated, saving the process of cooling the heat transfer medium from 60°C to 0°C).
[0033] Preferably, a thermometer 4 and a stirring paddle 5 are provided on the reaction kettle 1. It should be understood that this equipment can only be a laboratory-scale small-scale test equipment, and theoretically the volume of the reaction kettle cannot exceed 10L. It is not applicable due to energy consumption, integrated volume, and cleanliness requirements of large-scale production pharmaceutical equipment.
[0034] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present invention.
