Description

Technical Field

[0001] This utility model relates to the field of calcium gluconate processing technology, and in particular to a circulating cooling device for a calcium gluconate fermentation tank. Background Technology

[0002] In existing technologies, fermentation tanks are used for the processing of calcium gluconate. However, the fermentation process generates heat, which needs to be cooled. Current cooling technology involves installing a jacket around the fermentation tank and circulating tap water for cooling. However, the discharge of the cooled tap water is wasteful, and the cooling water within the jacket is prone to incomplete circulation, affecting the cooling effect and ultimately impacting the fermentation efficiency of calcium gluconate. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a circulating cooling device for calcium gluconate fermentation tanks, which enables reliable circulating cooling of the fermentation tanks with stable cooling effects and reduces water waste.

[0004] This utility model discloses a circulating cooling device for a calcium gluconate fermentation tank, including a fermentation tank. The side wall of the fermentation tank is divided into an inner wall and an outer wall, and a gap exists between the inner wall and the outer wall to form a cooling cavity. A spiral baffle is provided in the cooling cavity, which divides the cooling cavity into spiral cooling channels. It also includes a heat exchange box and a refrigerator. A delivery pump is provided inside the heat exchange box. The output pipe of the delivery pump passes through the heat exchange box and extends to the top of the fermentation tank, communicating with the cooling cavity at the top of the fermentation tank. A return pipe is provided at the bottom of the fermentation tank, communicating with the cooling cavity and connecting to the inside of the heat exchange box. A heat exchange coil is provided inside the heat exchange box, and both ends of the heat exchange coil are connected to the refrigerator.

[0005] A radiator is installed on the return pipe, and a cooling fan is installed on the radiator.

[0006] The structure of the radiator is as follows: its inlet and outlet are connected by several parallel flat hollow pipes; the return pipes are connected to the inlet and outlet of the radiator respectively, and the exhaust end of the cooling fan faces the flat hollow pipe area.

[0007] The reflux pipe is connected to the upper end of the heat exchange box, and the connection between the reflux pipe and the heat exchange box should be lower than the connection between the output pipe and the fermenter.

[0008] The circulating cooling device for a calcium gluconate fermenter obtained by this invention uses a refrigeration unit to cool the refrigerant and cool the medium in the heat exchange box to a suitable temperature. The medium circulating cooling chamber in the heat exchange box, through the cooling channel formed by the partition, allows for more thorough and sufficient medium exchange, greatly improving the stability and reliability of the cooling of the fermenter, ensuring the stability of the fermentation process, and ensuring the quality of calcium gluconate.

[0012] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0013] Example 1:

[0014] like Figures 1-3 As shown, this utility model discloses a circulating cooling device for a calcium gluconate fermentation tank, including a fermentation tank 1. The side wall of the fermentation tank 1 is divided into an inner wall 10 and an outer wall 11. A gap exists between the inner wall 10 and the outer wall 11 to form a cooling cavity 14. A spiral baffle 12 is provided in the cooling cavity 14, which divides the cooling cavity 14 into spiral cooling channels 13. It also includes a heat exchange box 2 and a refrigerator 5. A delivery pump 15 is provided inside the heat exchange box 2. The output pipe 3 of the delivery pump 15 passes through the heat exchange box 2 and extends to the top of the fermentation tank 1, and communicates with the cooling cavity 14 at the top of the fermentation tank 1. A return pipe 4 is provided at the bottom of the fermentation tank 1, which communicates with the cooling cavity 14 and is connected to the inside of the heat exchange box 2. A heat exchange coil 9 is provided inside the heat exchange box 2, and both ends of the heat exchange coil 9 are connected to the refrigerator 5.

[0015] The refrigeration unit 5 is a commercially available product. It is connected to the heat exchange coil 9 via pipes. The heat exchange coil 9, which is also the pipe, is filled with refrigerant. During normal use, the refrigeration unit 5 cools the refrigerant. The fermentation tank 1 has a known structure, with a cooling chamber 14 formed between its inner wall 10 and outer wall 11. The specific structural form is not limited. A transfer pump 15 is installed inside the heat exchange box 2. The heat exchange box 2 contains a medium. The transfer pump 15 delivers the medium to the cooling chamber 14 of the fermentation tank through the output pipe 3, and then flows back into the heat exchange box 2 through the return pipe 4. During this process, the medium cools the fermentation tank 1 as it passes through the cooling chamber 14. However, the return medium is at a higher temperature. When it enters the heat exchange box 2, it will cause the temperature of the medium inside the heat exchange box 2 to rise. Therefore, the heat exchange coil 9 is needed to cool the medium inside the heat exchange box 2 to achieve heat exchange between the medium and the refrigerant. Of course, in actual use, in order to maintain a suitable cooling effect of the medium on the fermenter 1, it is necessary to control the temperature of the medium. The temperature of the medium is controlled by the refrigerant temperature and flow rate of the refrigerant through the refrigeration unit 5, thereby achieving adjustable control of the cooling effect of the fermenter 1 with high stability. At the same time, in order to make the medium circulation in the cooling chamber 14 of the fermenter 1 more thorough, a spiral baffle 12 is set in the cooling chamber 14. The spiral baffle 12 forms a spiral cooling channel 13 in the cooling chamber 14. In this way, the medium entering from the top will inevitably flow downward along the cooling channel 13, and finally flow into the heat exchange box 2 from the bottom of the cooling chamber 14 through the return pipe 4, so as to achieve a more thorough and sufficient medium circulation and improve the more uniform and sufficient cooling of the fermenter 1.

[0016] The above technical solution utilizes a refrigeration unit 5 to cool the refrigerant, thereby cooling the medium. The medium can be recycled, ensuring stable cooling of the fermenter 1 without generating wastewater, reducing resource waste, and improving the cooling effect.

[0017] A radiator 6 is installed on the return pipe 4, and a cooling fan 7 is installed on the radiator 6. To reduce energy consumption, the radiator 6 on the return pipe 4 allows the medium, whose temperature rises after cooling the fermenter 1, to pass through the radiator 6 during its return flow, where it is cooled by the cooling fan 7, thereby lowering the temperature of the medium entering the heat exchanger 2. This reduces the cooling capacity required by the refrigerant in the subsequent cooling coils to cool the medium, thus reducing the power consumption of the chiller 5 and lowering energy consumption.

[0018] The structure of the radiator 6 is as follows: its inlet and outlet are connected by several parallel flat hollow pipes 8; the return pipes 4 are connected to the inlet and outlet of the radiator 6 respectively, and the air outlet of the cooling fan 7 faces the area of ​​the flat hollow pipes 8.

[0019] The radiator 6 has an inlet and an outlet, both internally containing a cavity. These cavities are connected by parallel, spaced-apart flat hollow pipes 8. The medium enters the inlet, flows through the flat hollow pipes 8 to the outlet, and then returns to the heat exchange chamber 2. During this process, the cross-section of the flat hollow pipes 8 is relatively small, resulting in a small flow rate for individual media, but maintaining a relatively large and stable overall flow rate. Furthermore, the large external surface area of ​​the flat hollow pipes 8 allows for faster heat dissipation when the cooling fan 7 blows air onto them, increasing the air velocity and thus rapidly cooling the internal medium. This reduces the initial temperature of the medium entering the heat exchange chamber 2, minimizing energy consumption during the cooling process.

[0020] The reflux pipe 4 is connected to the upper end of the heat exchange box 2, and the connection between the reflux pipe 4 and the heat exchange box 2 is lower than the connection between the output pipe 3 and the fermenter 1.

[0021] The transfer pump 15 delivers the medium to the cooling chamber 14 of the fermenter 1. When the cooling chamber 14 is full, because the connection between the output pipe 3 and the fermenter 1 is higher than the connection between the return pipe 4 and the heat exchange box 2, the medium can flow back to the heat exchange box 2 under pressure. Of course, to ensure a stable medium flow rate, the transfer pump 15 can continuously supply the medium to the cooling chamber 14 of the fermenter 1, using pressure to force the medium back to the heat exchange box 2. The flow rate of the medium is controllable, which facilitates the control of the cooling effect of the fermenter 1.
