Description

Technical Field

[0001] This utility model relates to the technical field of crystallization cooling equipment, and in particular to a high-efficiency cooling device for NMN crystallization without ethanol. Background Technology

[0002] As a high-value-added biomolecule, NMN has extremely high requirements for temperature and solvent purity during its crystallization process. Traditional crystallization processes often use ethanol as a solvent, but this poses risks of residue and flammability and explosion. Ethanol-free crystallization processes use water or other safe solvents, and require efficient cooling to control the crystallization rate and crystal purity.

[0003] A crystallization vessel is required during the NMN ethanol-free crystallization process. During crystallization, the outer wall of the crystallization vessel will generate high temperature. The traditional cooling method of crystallization vessel is mostly natural cooling, which often leads to low cooling efficiency of the crystallization vessel, thus affecting the crystallization rate and crystal purity of NMN ethanol-free crystallization. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a highly efficient cooling device for NMN crystallization without ethanol, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency cooling device for NMN ethanol-free crystallization, used for cooling crystallization tanks, includes:

[0007] A heat transfer component is provided, wherein a spiral channel is provided inside the crystallization tank, and the heat transfer component is disposed inside the spiral channel of the crystallization tank. The heat transfer component is configured as the side wall of the crystallization tank for heat transfer.

[0008] A liquid storage assembly is disposed on one side of the crystallization tank, and the liquid storage assembly is configured to transfer the liquid to the heat conduction assembly for liquid supply;

[0009] A liquid extraction assembly is disposed on a liquid storage assembly, and the liquid extraction assembly is configured to transfer the heat-conducting assembly to circulate and supply coolant.

[0010] Preferably, the outer wall of the crystallization tank is provided with a spiral side opening, and the spiral channel inside the crystallization tank is connected to the spiral side opening of its outer wall.

[0011] Preferably, the heat transfer component includes:

[0012] Copper tubes are fixedly and closely fitted onto the inner wall of one side of the spiral channel on the crystallization tank;

[0013] Several heat dissipation fins are fixedly installed on the outer wall of the copper tube, and there are gaps between the heat dissipation fins.

[0014] Preferably, the copper tube is arranged in a spiral structure, and the cross-section of the copper tube is arranged in a semi-circular hollow tube structure.

[0015] Preferably, both the copper tube and the heat dissipation fins are made of copper.

[0016] Preferably, the liquid storage assembly includes:

[0017] A cooling liquid storage tank is placed on one side of the crystallization tank. The cooling liquid storage tank has an inner cavity that stores coolant.

[0018] The inlet pipe is located at the top of the cooling liquid storage tank;

[0019] The valve is located on the cooling liquid storage tank;

[0020] Two semiconductor cooling plates are respectively installed on the outer walls of the cooling liquid storage tank on both sides.

[0021] Preferably, the liquid extraction assembly includes:

[0022] A pump is installed on the top side of the cooling liquid tank, and the pump's pumping pipe extends into the inner cavity of the cooling liquid tank.

[0023] The liquid supply hose has one end fixedly connected to the discharge end of the pump, and the other end fixedly connected to the top of the copper pipe.

[0024] The return hose has one end fixedly connected to the bottom of the copper pipe, and the other end extends into the inner cavity of the coolant reservoir.

[0025] In this application, a spiral channel and a spiral side opening are provided on the outer wall of the crystallization tank. A copper tube is fixedly installed on the inner wall of one side of the spiral channel, and several heat dissipation fins are fixedly installed on the outer wall of the copper tube. This allows the heat generated on the outer wall of the crystallization tank during NMN crystallization without ethanol to radiate to the outside, achieving a preliminary cooling effect on the copper tube. Simultaneously, when the pump is started, the coolant in the cooling storage tank, cooled by two semiconductor cooling plates attached to its outer walls on both sides, is transported upward to the top of the copper tube through the supply hose. During the spiral downward flow of the coolant in the copper tube, the copper tube can be cooled by water. The cooled water flows back to the cooling storage tank through the return hose for recooling, achieving a circulating cooling effect of the cooling water. This, in turn, provides efficient cooling of the crystallization tank during NMN crystallization without ethanol, ensuring the crystallization rate and crystal purity of NMN without ethanol.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This embodiment discloses a high-efficiency cooling device for NMN ethanol-free crystallization, including: as follows Figure 1 The crystallization tank 100, the liquid storage assembly 300, and the liquid extraction assembly 400 are shown; as follows: Figure 5 The heat transfer and conduction component 200 shown is shown.

[0035] like Figure 2As shown, the crystallization tank 100 has a chamber to facilitate the crystallization of NMN without ethanol. When NMN crystallizes without ethanol, heat is generated on the outer wall of the crystallization tank 100. To cool the outer wall of the crystallization tank 100, a spiral channel 101 is provided inside the crystallization tank 100. A heat transfer component 200 is installed inside the spiral channel 101 of the crystallization tank 100. The heat transfer component 200 is used to transfer heat to the side wall of the crystallization tank 100. The heat transfer component 200 includes a copper tube 201 and several heat dissipation fins 202. The copper tube 201 is spirally arranged and fixedly attached to the inner wall of one side of the spiral channel 101 on the crystallization tank 100. The copper tube 201 is made of copper material and its cross-section is a semi-circular hollow tube structure. The design facilitates heat conduction from the outer wall of the crystallization tank 100 to the copper tube 201. Several heat dissipation fins 202 are fixedly installed on the outer wall of the copper tube 201 to facilitate heat conduction from the copper tube 201 to the heat dissipation fins 202. The heat dissipation fins 202 are made of copper material, and there are gaps between the heat dissipation fins 202 to increase the contact area between the heat dissipation fins 202 and the air, so as to facilitate the dissipation of heat into the spiral channel 101. At the same time, a spiral side opening 102 is opened on the outer wall of the crystallization tank 100, and the spiral channel 101 inside the crystallization tank 100 is connected to the spiral side opening 102 on its outer wall, so as to facilitate heat convection between the heat in the spiral channel 101 and the outside air, thereby achieving the heat dissipation and cooling effect of the copper tube 201.

[0036] like Figure 2 As shown, the liquid storage assembly 300 is disposed on one side of the crystallization tank 100. The liquid storage assembly 300 is configured to transfer the liquid to the heat conduction assembly 200 for liquid supply. The liquid storage assembly 300 includes: a cooling liquid storage tank 301, an inlet pipe 302, a valve 303, and two semiconductor cooling plates 304. The cooling liquid storage tank 301 is placed on one side of the crystallization tank 100. The cooling liquid storage tank 301 has an inner cavity that stores coolant. The cooling liquid storage tank 301 is provided with an inlet pipe 302 to facilitate the injection of coolant into the inner cavity of the cooling liquid storage tank 301. The inlet pipe 302 is provided with a valve 303 to facilitate the control of the injection of coolant into the inlet pipe 302. The two semiconductor cooling plates 304 are respectively disposed on the two outer walls of the cooling liquid storage tank 301. The continuous cooling effect of the coolant in the cooling liquid storage tank 301 is achieved by the two semiconductor cooling plates 304 adhering to the two outer walls of the cooling liquid storage tank 301.

[0037] Continue as Figure 2As shown, the liquid extraction assembly 400 is mounted on the liquid storage assembly 300. The liquid extraction assembly 400 is configured to transfer the heat transfer assembly 200 to circulate and supply coolant. The liquid extraction assembly 400 includes a pump 401, a supply hose 402, and a return hose 403. The pump 401 is mounted on the top side of the coolant storage tank 301. The pumping end of the pump 401 extends into the inner cavity of the coolant storage tank 301. The discharge end of the pump 401 is connected to one end of the supply hose 402. The other end of the supply hose 402 is fixedly connected to the top end of the copper pipe 201. One end of the return hose 403 is fixedly connected to the bottom of the copper pipe 201, and the other end of the return hose 403 extends into the inner cavity of the cooling liquid tank 301. When the pump 401 is started, the cooled coolant in the cooling liquid tank 301 is transported upward to the top of the copper pipe 201 through the supply hose 402. During the spiral downward flow of the coolant in the copper pipe 201, the copper pipe 201 can be cooled by water cooling. The cooled water flows back to the cooling liquid tank 301 through the return hose 403 for re-cooling, thus achieving the effect of circulating cooling water.

[0038] In this application, a spiral channel 101 and a spiral side opening 102 are provided on the outer wall of the crystallization tank 100. A copper tube 201 is fixedly installed on the inner wall of one side of the spiral channel 101. Several heat dissipation fins 202 are fixedly arranged on the outer wall of the copper tube 201. The heat generated by the outer wall of the crystallization tank 100 during NMN crystallization without ethanol can be radiated to the outside, achieving a preliminary cooling effect on the copper tube 201. At the same time, when the pump 401 is started, the two halves of the cooling liquid tank 301, which are attached to the outer walls on both sides, are cooled. After being cooled by the conductor cooling plate 304, the coolant is transported upward to the top of the copper pipe 201 via the supply hose 402. As the coolant flows downward in a spiral motion within the copper pipe 201, it achieves water-cooling and temperature reduction. The cooled water then flows back to the cooling storage tank 301 via the return hose 403 for recooling, achieving a circulating cooling effect. This provides efficient cooling for the crystallization tank 100 during NMN ethanol-free crystallization, ensuring the crystallization rate and crystal purity of NMN ethanol-free crystallization.
