Embodiment 1

[0031] see Figure 1-3 As shown, a constant temperature cultivation device suitable for the experimental research of complex crystals provided by the embodiment of the present invention includes a cultivation box 1 and a cultivation chamber 3, and the cultivation chamber 1 is provided with a constant temperature chamber 2 for adjusting the temperature of the cultivation chamber 3 The two sides of the bottom of the thermostatic chamber 2 are respectively connected to the heating chamber 4 and the freezing chamber 5 through the connecting pipe 201. Both the heating chamber and the freezing chamber are filled with a heat transfer liquid, and the temperature of the heat transfer liquid is controlled by the heating device or the refrigeration device of the bottom plate respectively. adjust. Each connecting pipe 201 is provided with a liquid suction pump 202, through which the liquid in the corresponding heating chamber and the freezing chamber can be pumped to adjust the temperatur...

Embodiment 2

[0039] see Figure 3-5 As shown, the difference from the above embodiment is that, in order to facilitate the study of the influence of different rotation speeds on the crystal growth of complexes, each incubation chamber 3 is provided with a crystallizer 9 that is rotatably connected to the side wall of the incubation chamber 3 , the top outer wall of each crystallizer 9 is rotatably connected to the inner wall of the corresponding cultivation chamber 3 through a bearing 10, and each bearing 10 is provided with a circle of the first ring composed of several gear teeth near the top of the inner ring of the crystallizer 9 corresponding to it. A gear 101, the top side of each incubation chamber 3 is provided with a motor 11, and the output shaft of each motor 11 is connected with a second gear 111, and each second gear 111 is installed on the corresponding first gear 101 and meshes with the teeth of the first gear 101. The output shaft on the motor is fixedly connected with the...

Embodiment 3

[0044] see image 3 and Figure 5 As shown, the difference from the above-mentioned embodiment is that each crystallizer 9 is provided with a scale on the inner wall, which facilitates the quantitative addition of the liquid required for the growth of complex crystals. In order to facilitate the study of the influence of the magnetism of the magnet on the crystal growth of the complex, the bottom of each incubation chamber 3 is provided with a permanent magnet 13, and each incubation chamber 3 and its corresponding crystallizer 9 are jointly enclosed to form a space for installing the permanent magnet 13. The installation chamber 14 is provided with an elastic clip 141 for clamping the permanent magnet 13 inside the installation chamber 14, so that the permanent magnet can be stably mounted on the bottom of the installation chamber.

[0045] In this embodiment, a permanent magnet is installed at the bottom of each incubation chamber, which can be used to study the influence o...

Abstract

The invention provides a constant-temperature cultivation device suitable for coordination compound crystal experimental research. The constant-temperature cultivation device comprises a cultivation box, which is internally provided with a constant-temperature chamber, wherein the two sides of the bottom of the constant-temperature chamber are respectively connected with a heating chamber and a freezing chamber through connecting pipes, each connecting pipe is provided with a liquid sucking pump, a plurality of cultivation chambers are uniformly arranged on the peripheral side of the top of the constant-temperature chamber, the side walls of each cultivation chamber are respectively provided with a cavity for passing through of a constant-temperature liquid, a liquid inlet and a liquid outlet are formed in the two sides of each cavity, each liquid inlet is connected with the constant-temperature chamber through a constant-temperature pipe, a buffer chamber is arranged on one side of the constant-temperature chamber, and each liquid outlet is connected with the heating chamber and the freezing chamber through the buffer chamber. According to the invention, with the constant-temperature cultivation device, the problem that the existing constant-temperature device cannot respectively heat each crystallizer so as not to research the growth conditions of coordination compound crystals under different constant-temperature conditions is solved.

Description

technical field [0001] The invention relates to the field of experimental research equipment for crystal cultivation, in particular to a constant temperature cultivation device suitable for the experimental research of complex crystals. Background technique [0002] Studying the growth of crystals, especially single crystals, is an important field in synthetic chemistry experiments, and the methods usually used are crystallization and recrystallization. Crystallization methods include cooling crystallization and evaporation crystallization. Now in the process of industrial production, solvent replacement crystallization is also used, that is, a poor solvent is slowly added to a certain volume of good solvent solution and replaced with a poor solvent. When the temperature is properly lowered Crystals can be precipitated. [0003] However, in the crystallization process, it may be due to the uncontrollable change of temperature with the amount of crystal growth, or the uncont...
