[0023] Embodiment

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a low-temperature storage tank for spirulina liquid, including a temperature control component 1. The temperature control component 1 includes an inner tank 11, a spiral cooling pipe 12, a heat preservation tank 13, an outer tank 14, a coolant storage tank 15, a circulation pump 16, an infusion pipe 17, a heat exchanger 18, a cooling fan 19 and a controller 20. The outer side wall of the inner tank 11 is fixedly connected with a spiral cooling pipe 12. The outer side wall of the spiral cooling pipe 12 is fixedly connected with a heat preservation tank 13. The outer side wall of the heat preservation tank 13 is fixedly connected with an outer tank 14. One side of the outer side wall of the outer tank 14 is fixedly connected with a coolant storage tank 15. The liquid inlet end of the spiral cooling pipe 12 penetrates through the middle part of the lower surface of the coolant storage tank 15. A circulation pump 16 is installed at the liquid inlet end of the spiral cooling pipe 12. The rear part of the upper surface of the coolant storage tank 15 is communicated with a heat exchanger 18 through an infusion pipe 17. The liquid outlet end of the spiral cooling pipe 12 is communicated with the liquid inlet end of the heat exchanger 18. A cooling fan 19 is fixedly connected to the side of the heat exchanger 18 away from the outer tank 14. A controller 20 is fixedly connected to the front part of the outer side wall of the outer tank 14. The input ends of the circulation pump 16 and the cooling fan 19 are electrically connected to the output end of the controller 20. The coolant inside the spiral cooling pipe 12 circulates, thereby cooling the inner cavity between the inner tank 11 and the heat preservation tank 13, and further cooling the spirulina liquid inside the inner tank 11. The heat preservation tank 13 is convenient for maintaining the temperature of the spirulina liquid.

[0025] In this embodiment, specifically: a temperature sensor 21 is arranged on one side of the inner bottom wall of the inner tank 11. The output end of the temperature sensor 21 is electrically connected to the input end of the controller 20. The temperature sensor 21 is convenient for real-time monitoring of the temperature of the spirulina liquid inside the inner tank 11.

[0026] In this embodiment, specifically: a liquid inlet pipe 22 is communicated with the center of the upper surface of the inner tank 11. The top of the liquid inlet pipe 22 penetrates through the center of the inner top walls of the heat preservation tank 13 and the outer tank 14. A sealing cover 23 is threadedly connected to the top of the outer side wall of the liquid inlet pipe 22. A safety valve 24 is installed at the center of the upper surface of the sealing cover 23. The input end of the safety valve 24 is electrically connected to the output end of the controller 20. The safety valve 24 is convenient for automatically opening when the pressure in the inner tank 11 is too high, balancing the internal and external pressures, thereby preventing the inner tank 11 from being damaged due to excessive pressure.

[0027] In this embodiment, specifically: a pressure sensor 25 is arranged on one side of the inner top wall of the inner tank 11. The output end of the pressure sensor 25 is electrically connected to the input end of the controller 20. The pressure sensor 25 is convenient for real-time monitoring of the internal pressure of the inner tank 11.

[0028] In this embodiment, specifically: a liquid level sensor 26 is arranged on the other side of the inner bottom wall of the inner tank 11. The output end of the liquid level sensor 26 is electrically connected to the input end of the controller 20. The liquid level sensor 26 is convenient for real-time monitoring of the liquid level of the spirulina liquid inside the inner tank 11.

[0029] In this embodiment, specifically: an anti-corrosion layer 27 is fixedly connected to the inner side wall of the inner tank 11. Through the anti-corrosion property of the anti-corrosion layer 27, chemical reactions between the spirulina liquid and the inner tank 11 are prevented, thus preventing the deterioration of the spirulina liquid.

[0030] In this embodiment, specifically: a liquid outlet pipe 28 communicates with the center of the lower surface of the inner tank 11. The liquid outlet end of the liquid outlet pipe 28 penetrates through the inner bottom walls of the heat preservation tank 13 and the outer tank 14 at the center. A solenoid valve 29 is installed on one side of the outer side wall of the liquid outlet pipe 28 close to the liquid outlet end. The input end of the solenoid valve 29 is electrically connected to the output end of the controller 20. By controlling the opening and closing of the solenoid valve 29 on the liquid outlet pipe 28 through the controller 20, it is convenient to output the spirulina liquid through the liquid outlet pipe 28.

[0031] In this embodiment, specifically: a plurality of support columns 30 are welded in a circular shape on the outer sides of the upper surface and the lower surface of the inner tank 11. The far ends of the plurality of support columns 30 are respectively welded to the outer side of the inner top wall and the inner bottom wall of the outer tank 14. A support frame 31 is welded to the bottom of the outer side wall of the outer tank 14. The inner tank 11 and the outer tank 14 are connected by the plurality of support columns 30, thereby increasing the overall firmness. Through the support of the support frame 31, the stability of the entire storage tank is increased.

[0032] Working principle or structural principle: During use, the spirulina liquid is injected into the inner tank 11 through the liquid inlet pipe 22. During the injection process, the liquid level sensor 26 will monitor the liquid level of the spirulina liquid in real time and feed the data back to the controller 20. When the liquid level reaches the preset value, the controller 20 will send a signal to prompt the operator to stop injecting. At the same time, the sealing cover 23 will ensure the sealing of the liquid inlet pipe 22 to prevent the leakage of the spirulina liquid. After the injection of the spirulina liquid is completed, the controller 20 will start the circulation pump 16 to make the coolant in the coolant storage tank 15 circulate through the spiral cooling pipe 12. When the coolant flows in the spiral cooling pipe 12, it will absorb the heat between the inner tank 11 and the heat preservation tank 13, thereby realizing the cooling of the spirulina liquid. At the same time, the temperature sensor 21 will monitor the temperature of the spirulina liquid inside the inner tank 11 in real time and feed the data back to the controller 20. If the temperature is higher than the set value, the controller 20 will adjust the rotation speed of the circulation pump 16 to increase the flow rate of the coolant, thereby accelerating the cooling speed. If the temperature is lower than the set value, the controller 20 will reduce the flow rate of the coolant to avoid excessive cooling. In order to maintain the cooling effect of the coolant, the controller 20 will also start the cooling fan 19 to dissipate heat from the heat exchanger 18. Through the action of the cooling fan 19, the heat in the heat exchanger 18 can be dissipated in time to ensure the continuous cooling effect of the coolant. During storage, the pressure sensor 25 will monitor the pressure inside the inner tank 11 in real time. If the pressure is too high, the controller 20 will start the safety valve 24 to balance the internal and external pressures and prevent the inner tank 11 from being damaged due to excessive pressure.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
