[0002] A continuous crystallizer is a device used in the fields of chemical industry, pharmacy, inorganic salts, etc. Its main function is to separate solutes and crystals in a solution. The continuous crystallizer mainly consists of an external tube heat exchanger, a circulation pump, and a crystallizer.

[0003] Specifically, the circulation pump drives the material to circulate and exchange heat in a large flow between the external heat exchanger and the crystallizer and is continuously fed into the crystallizer. At the same time, the external heat source heats the material, and the water in the high-temperature material continuously evaporates, increasing the concentration of the material. Thus, crystals continuously precipitate in the crystallizer.

[0004] However, the circulation pump generates periodic flow pulsations during operation, which causes pipeline vibrations. Long-term pipeline vibrations will exacerbate the wear of equipment components, shorten the service life of the equipment, and in severe cases, will cause fatigue damage to the welds and connections of the pipeline, increasing the risk of leakage and failure. Therefore, an efficient and stable continuous crystallizer is needed to solve the above problems. Summary of the Utility Model

[0026] The following further describes the present utility model in conjunction with embodiments.

[0027] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the concept of the present utility model belongs to the scope protected by the present utility model.

[0028] Please refer to Figures 1-5 , the present utility model provides an efficient and stable continuous crystallizer, including:

[0029] A circulation pump 1, the circulation pump 1 includes a stirring blade 11 for stirring materials;

[0030] A circulation pipeline 2, the stirring blade 11 extends into the circulation pipeline 2. By setting the stirring blade 11, the materials in the circulation pipeline 2 are fully stirred, so as to facilitate the subsequent crystal precipitation;

[0031] A shockproof device 3, the shockproof device 3 includes a mounting frame 31 fixedly installed on the ground, a shockproof spring 32 connected to the inner wall of the mounting frame 31, and a support member 33. The mounting frame 31 is coaxial with the circulation pipeline 2. The support member 33 is fixedly installed at one end of the shockproof spring 32 away from the connecting mounting frame 31. There are two support members 33, and the two support members 33 are symmetrically distributed around the axis of the mounting frame 31. The circulation pipeline 2 is inserted between the two support members 33. When the circulation pump 1 operates to generate periodic flow pulsations and cause the circulation pipeline 2 to vibrate, the shockproof spring 32 absorbs and attenuates the vibration energy of the circulation pipeline 2, thereby reducing equipment damage caused by vibration; and the shockproof spring 32 can also absorb the thermal expansion and contraction of the circulation pipeline 2 due to temperature changes, reducing the stress caused by temperature changes;

[0032] A heat exchanger 4, the heat exchanger 4 and the circulation pump 1 are connected through the circulation pipeline 2. By setting the heat exchanger 4, the materials in the heat exchanger 4 are continuously heated by an external heat source;

[0033] The crystallizer 5, the crystallizer 5, the circulation pump 1, and the heat exchanger 4 are connected through a circulation pipeline 2. Crystals of the high-temperature material are precipitated in the crystallizer 5, and the moisture in the high-temperature material flows out of the equipment in the form of water vapor.

[0034] The circulation pipeline 2 further includes a corrugated pipe 21. The corrugated pipe 21 is installed at the connection of the circulation pump 1 and the heat exchanger 4. The corrugated pipe 21 can effectively eliminate the vibration caused by the operation of the circulation pump 1 and the stress generated due to the thermal expansion and contraction of the circulation pipeline 2.

[0035] The surface of the crystallizer 5 in contact with the material is polished, thus effectively preventing the material from crystallizing on the inner wall of the crystallizer 5 and preventing the clogging of the crystallizer 5.

[0036] The crystallizer 5 further includes a display instrument 51 for real-time monitoring of the operation of the equipment. The display instrument 51 is installed on the circulation pipeline 2. By setting the display instrument 51, workers can monitor the operation of the equipment in real time, which is convenient for timely adjusting the operating conditions of the equipment and enabling the equipment to operate stably.

[0037] The crystallizer 5 forms a steam outlet 52 and a discharge port 53 communicated with the steam outlet 52.

[0038] The circulation pipeline 2 further includes a feeding port 22 for feeding materials. The feeding port 22 is formed on the horizontal section of the circulation pipeline 2, and the feeding port 22 is arranged in the same direction as the stirring blade 11.

[0039] The working principle and usage process of the present utility model:

[0040] The material enters the circulation pipeline 2 from the feeding port 22 and is continuously stirred by the stirring blade 11 of the circulation pump 1. Subsequently, under the drive of the circulation pump 1, it reaches the heat exchanger 4 through the circulation pipeline 2 and is heated by an external heat source. The high-temperature material enters the crystallizer 5 and begins to precipitate crystals. Among them, the moisture in the high-temperature material is evaporated and forms water vapor, which flows out from the steam outlet 52. The crystals in the material are precipitated, and workers can take out the precipitated crystals from the discharge port 53.

[0041] Since the material is continuously fed into the circulation pipeline 2 and the external heat source continuously heats the material, the moisture in the high-temperature material in the crystallizer 5 is continuously evaporated, and the concentration of the material is continuously increased. Therefore, crystals are continuously precipitated in the crystallizer 5, and so on.

[0042] Meanwhile, since the circulating pump 1 may generate periodic flow pulsations during operation, causing the circulating pipeline 2 inserted between the two support members 33 to vibrate, and then driving the shock-absorbing spring 32 connected to the support member 33 to vibrate together. The shock-absorbing spring 32 absorbs and attenuates the vibration energy of the circulating pipeline 2, thereby reducing equipment damage caused by vibration; and the shock-absorbing spring 32 can also absorb the thermal expansion and contraction of the circulating pipeline 2 due to temperature changes, reducing the stress caused by temperature changes;

[0043] It is worth mentioning that the circulating pump 1 adopts a variable-frequency speed-regulating motor, enabling the circulating pump 1 to adjust the flow rate of the material in the circulating pipeline 2 according to the load condition, so that factors such as the heat exchange effect of the heat exchanger 4, the fluid resistance in the circulating pipeline 2, and the stirring intensity of the stirring blade 11 reach an ideal state;

[0044] In addition, workers can monitor the operation status of the equipment in real time through the display instrument 51, which is convenient for workers to adjust the operation conditions of the equipment in a timely manner, enabling the equipment to operate efficiently, energy-savingly, stably and continuously.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
