Technical Field

[0002] Currently, the commonly used crystallization methods are evaporation crystallization and cooling crystallization. Continuous crystallizers combine these two crystallization processes. However, when the crystal slurry circulates in the separation chamber and crystals erupt, the liquid surface will boil, resulting in a large number of microcrystals. Over time, these microcrystals will adhere to the walls and accumulate within the fluctuation range. When they reach a certain scale, they will fall and block the heat exchange tubes and circulating pumps, causing production accidents. Utility Model Content

[0030] Please see Figure 1-3 This utility model provides a technical solution: a crystallization device for preventing material from adhering to the wall, comprising:

[0031] Crystallization tank 100; wherein, crystallization tank 100 stores crystal slurry, and a retainer 200 is fixedly installed along the outer wall of crystallization tank 100. The retainer 200 is provided with grooves 201. The position of the retainer 200 is designed and is set at the height of the crystal slurry. The grooves 201 are spirally coiled along the outer wall of crystallization tank 100 to form a spiral structure.

[0032] Coil 300; In addition, coil 300 is described in detail. Coil 300 is inserted into groove 201. In this way, coil 300 is fixedly coiled around the outer wall of crystallization tank 100 along groove 201. Coil 300 is set at the height of the crystal slurry plane. The size of coil 300 matches groove 201. Coil 300 is a hollow tube made of heat-conducting material. The contact surface between coil 300 and crystallization tank 100 is flat. This ensures that the temperature of the liquid flowing in coil 300 is better transferred to crystallization tank 100.

[0033] The two ends of the coil 300 extend out of the retainer 200. The ends of the two coils 300 are respectively set as inlet 301 and outlet 302. The pump body is connected to the outside and connected to the inlet 301 and outlet 302 respectively to form a liquid circulation. Specifically, 80-degree condensed water is added for circulation until the outer wall temperature of the part of the crystallizer 100 where the coil 300 is wound is heated to 75 degrees. At the same time, the crystal slurry is also heated, which effectively reduces the excessive powder crystals that appear during cooling crystallization, and also reduces the viscosity of the crystal slurry, reducing the risk of wall adhesion and material falling and clogging the heating pipe and circulation pump.

[0034] In some embodiments, the coil 300 is wound at least once around the crystallizer 100.

[0035] In some embodiments, connectors 303 are fixedly provided at both the inlet 301 and the outlet 302. The connectors 303 facilitate the connection of external pipes to the coil 300, and also facilitate disassembly and maintenance.

[0036] In some embodiments, a plurality of fixing holes 202 are uniformly provided on the contact surface between the retainer 200 and the crystallization tank 100, and at a position between the two grooves 201. The fixing holes 202 are used to fasten the retainer 200 to the crystallization tank 100 with bolts to ensure the stability of the retainer 200. At the same time, the setting of the fixing holes 202 also facilitates the adjustment of the position of the retainer 200 to accommodate crystallization tanks 100 of different sizes.

[0037] In some embodiments, the inner wall of the coil 300 is provided with spiral guide vanes to enhance the turbulence effect of the heat exchange medium. When the heat exchange medium flows in the coil 300, it is guided by the spiral guide vanes to form turbulence, making the heat exchange more complete.

[0038] In some embodiments, the inner wall of the crystallization tank 100 is coated with a polytetrafluoroethylene (PTFE) anti-stick coating. The PTFE anti-stick coating has excellent anti-stick properties, which can reduce the adhesion of materials to the inner wall of the crystallization tank 100 and further reduce the wall-hanging phenomenon.

[0039] In some embodiments, the retainer 200 is made of aluminum alloy and the surface is anodized. Aluminum alloy has properties such as light weight, high strength and corrosion resistance, which can meet the usage requirements of the retainer 200.

[0040] In some embodiments, the cross-section of the groove 201 is semi-circular, and its radius is 0.5-1mm larger than the outer diameter of the coil 300. This design can ensure that the coil 300 is stably inserted into the groove 201, while avoiding excessive friction between the coil 300 and the groove 201, which would affect its service life.

[0041] In some embodiments, a temperature sensor is also included, which is disposed on the inner wall of the crystallization tank 100 to observe the temperature of the crystallization slurry, thereby changing the temperature of the condensate.

[0042] In some embodiments, the connector 303 adopts a quick-release flange structure, which can be quickly connected and disconnected, improving work efficiency.

[0043] Working Principle: The crystallization tank 100 stores crystal slurry, which is the main container for the crystallization process. A retainer 200 is fixedly installed on the outer wall of the crystallization tank 100, and has grooves 201 on it. The retainer is positioned at the height of the crystal slurry. The grooves 201 spirally coil along the outer wall of the crystallization tank, forming a spiral structure. The coil 300 is inserted into the grooves 201 and fixedly coiled along the outer wall of the crystallization tank. The dimensions of the coil 300 match the grooves 201, and it is a hollow tube made of heat-conducting material, ensuring that the temperature of the liquid flowing inside the coil can be effectively transferred to the crystal slurry in the crystallization tank. The two ends of the coil 300 extend beyond the retainer 200, and are respectively provided with an inlet 301 and an outlet 302. An externally connected pump body forms a liquid circulation system. In the liquid circulation system, the pump body sends 80-degree condensate into the inlet 301 of the coil 300. The condensate flows in the coil and transfers heat to the outer wall of the crystallizer 100 through heat conduction, heating it to 75 degrees. At the same time, the condensate circulation in the coil also heats the crystal slurry, effectively reducing the formation of excessive powder crystals during the cooling crystallization process, reducing the viscosity of the crystal slurry, and reducing the phenomenon of adhering to the wall.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
