Detailed Implementation

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a static crystallization tank, including an outer shell 1, a heat exchange tank 2 fixedly installed on the top of the outer shell 1, a cleaning port on the top of the heat exchange tank 2, the bottom of the heat exchange tank 2 extending into the interior of the outer shell 1, an insulation layer 3 filling the space between the outer shell 1 and the heat exchange tank 2, a cover plate 4 on the top of the heat exchange tank 2, and a pressing assembly disposed on the outer shell 1 and the cover plate 4. The pressing assembly is used to press the cover plate 4 onto the top of the heat exchange tank 2. An installation groove is formed on the bottom inner side of the cover plate 4, and a sealing ring 5 is fitted inside the installation groove. The bottom of the sealing ring 5 contacts the top of the heat exchange tank 2, thereby increasing the sealing between the heat exchange tank 2 and the cover plate 4.

[0022] Furthermore, the pressing assembly includes a connecting block 6, a connecting rod 7, a threaded rod 8, and a steering wheel 9. The connecting block 6 is fixedly installed on one side of the outer wall of the housing 1. The connecting rod 7 is rotatably installed on the connecting block 6. The threaded rod 8 is threadedly installed on the connecting rod 7. The steering wheel 9 is fixedly installed on the top of the threaded rod 8. The bottom of the threaded rod 8 is rotatably installed on the top of the cover plate 4. When the steering wheel 9 is manually turned, it drives the threaded rod 8 to rotate, causing the threaded rod 8 and the cover plate 4 to move downwards. This allows the cover plate 4 to be fixed on the top of the heat exchange tank 2, sealing the cleaning port and preventing contact with air during the crystallization process. After the crystallization tank is used, the cover plate 4 can be removed from the cleaning port for easy cleaning of the inside of the heat exchange tank 2.

[0023] Furthermore, a pressure sensor 11 and a temperature sensor 12 are fixedly installed on the cover plate 4. The detection ends of the pressure sensor 11 and the temperature sensor 12 both penetrate the cover plate 4 and extend into the interior of the heat exchange tank 2, making it easy to observe the pressure and temperature inside the heat exchange tank 2.

[0024] Furthermore, the heat exchange tank 2 has a heat exchange cavity 13. An inlet pipe 14 and an outlet pipe 15 are fixedly installed on one side of the outer shell 1 and the other side of the heat exchange tank 2. One end of the inlet pipe 14 is connected to one end of the heat exchange cavity 13, and one end of the outlet pipe 15 is connected to the other end of the heat exchange cavity 13. One end of the water pump is connected to the inlet pipe 14 through a connecting pipe. By starting the water pump, the water pump draws out the hot fluid. The hot fluid enters the heat exchange cavity 13 through the connecting pipe and the inlet pipe 14, which heats up the heat exchange tank 2, heats the material, and drives the material to melt. Then, the water pump draws out the cold fluid. The cold fluid enters the heat exchange cavity 13 through the connecting pipe and the inlet pipe 14, which cools down the heat exchange tank 2, gradually cooling or concentrating the material to form high-purity crystals.

[0025] Furthermore, a support leg 17 is fixedly installed on the outer wall of the outer shell 1, and a caster 18 is movably installed on the bottom of the support leg 17. There are four support legs 17 and four casters 18 arranged in a circular array. The casters 18 are equipped with foot brakes to facilitate the movement and fixation of the crystallization tank.

[0026] Furthermore, a drain pipe 16 is fixedly installed at the bottom of the outer shell 1 and the bottom of the heat exchange tank 2. The drain pipe 16 is equipped with a valve to facilitate the discharge of cleaning fluid.

[0027] Furthermore, the cover plate 4 is fitted with a transparent observation window 10, which allows a clear view of the interior of the heat exchange tank 2, facilitating the recording of the material crystallization process.

[0028] Working principle: The substance is poured into the heat exchange tank 2. By manually pushing the connecting rod 7 and the cover plate 4, the cover plate 4 is moved to the top of the heat exchange tank 2. Then, the steering wheel 9 is manually turned, which drives the threaded rod 8 to rotate, causing the threaded rod 8 and the cover plate 4 to move downwards, thus fixing the cover plate 4 to the top of the heat exchange tank 2. Then, one end of the water pump is connected to the inlet pipe 14 through the connecting pipe. By starting the water pump, the water pump draws out the hot fluid, which enters the heat exchange chamber 13 through the connecting pipe and the inlet pipe 14, heating the heat exchange tank 2 and melting the substance. Then, the water pump draws out the cold fluid, which enters the heat exchange chamber 13 through the connecting pipe and the inlet pipe 14, cooling the heat exchange tank 2 and gradually cooling or concentrating the substance to form high-purity crystals.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
