[0024] The following description, with reference to the accompanying drawings, describes a cooling water recovery system 1 for a fluid food storage tank according to an embodiment of the present invention.

[0025] like Figure 1 As shown, the fluid food storage tank cooling water recovery system 1 according to an embodiment of the present invention includes a fluid food storage tank 10, a recovery tank 20, a recovery tank water level detection device 30, a recovery tank pumping device 40, and a filtration device 50.

[0026] The fluid food storage tank 10 is equipped with a cooling water inlet 11 and a cooling water outlet 12. The recovery tank 20 is equipped with a recovery tank inlet 21 and a recovery tank outlet 22. The recovery tank inlet 21 is connected to the cooling water outlet 12, and the recovery tank outlet 22 is connected to the tap water network 2. A recovery tank water level detection device 30 is installed on the recovery tank 20. A recovery tank pumping device 40 is connected between the recovery tank outlet 22 and the tap water network 2, and the recovery tank pumping device 40 is electrically connected to the recovery tank water level detection device 30. A filter device 50 is connected between the recovery tank outlet 22 and the tap water network 2.

[0027] Specifically, cooling water enters the fluid food storage tank 10 through the cooling water inlet 11, cools the fluid food storage tank 10, and then exits through the cooling water outlet 12. Afterward, it enters the recycling tank 20 through the recycling tank inlet 21 for storage. The recycling tank water level detection device 30 detects the water level in the recycling tank 20. When the water level detection device 30 detects a high water level in the recycling tank 20, the recycling tank pumping device 40 pumps the water through the recycling tank outlet 22 to the filtration device 50 for filtration. The filtered water then enters the tap water network 2 for recycling. When the water level detection device 30 detects a low water level in the recycling tank 20, the recycling tank pumping device 40 stops operating.

[0028] Water supply network 2 can be the factory's water supply network. The water source for cooling water inlet 11 can also be supplied by water supply network 2.

[0029] According to the embodiment of the present invention, the cooling water recovery system 1 for fluid food storage tanks is equipped with a filter device 50. After the water used to cool the fluid food storage tank 10 is filtered by the filter device 50, it is returned to the tap water network 2. Compared with the related technology that directly discharges cooling water, this system can not only realize the recycling of cooling water, recovering 800 kg of water after each cooling, improving water resource utilization, reducing water costs, and contributing to sustainable development, but also remove impurities mixed into the cooling water during the cooling process using the filter device 50, ensuring the water quality of the water entering the tap water network 2 and improving the reliability of subsequent water use.

[0030] Furthermore, since the sterilization and cooling of the fluid food storage tank 10 are intermittent, the cooling water can be stored in the recovery tank 20. By installing a recovery tank water level detection device 30 and a recovery tank pumping device 40, the pumping device 40 can start and stop based on the water level detected by the water level detection device 30 in the recovery tank 20. When the water level is high, the pumping device 40 operates, delivering water to the tap water network 2 to prevent overflow due to excessively high water levels. When the water level is low, the pumping device 40 stops operating to prevent it from running dry due to insufficient water supply, thus protecting its lifespan and preventing damage caused by idling. Therefore, through the cooperation of the recovery tank water level detection device 30 and the recovery tank pumping device 40, the water level in the recovery tank 20 can be controlled within a reasonable range, facilitating the continuous, efficient, and stable operation of the fluid food storage tank cooling water recovery system 1.

[0031] Therefore, the fluid food storage tank cooling water recovery system 1 according to the present utility model has the advantages of high water resource utilization, reduced water cost, reliable water quality recovery, and continuous and stable operation.

[0032] The following description, with reference to the accompanying drawings, describes a specific embodiment of a fluid food storage tank cooling water recovery system 1 according to the present invention.

[0033] In some specific embodiments of this utility model, such as Figure 1 As shown, the fluid food storage tank cooling water recovery system 1 according to an embodiment of the present invention includes a fluid food storage tank 10, a recovery tank 20, a recovery tank water level detection device 30, a recovery tank pumping device 40, and a filtration device 50.

[0034] Specifically, such as Figure 1 As shown, the recovery tank water level detection device 30 includes a high water level detection device 31 and a low water level detection device 32. The recovery tank pumping device 40 operates when the high water level detection device 31 is triggered. The recovery tank pumping device 40 stops when the low water level detection device 32 is triggered. Specifically, the high water level detection device 31 is located above the low water level detection device 32 (vertical direction as shown by the arrow in the figure). When the water level in the recovery tank 20 reaches a predetermined low water level, the low water level detection device 32 is triggered; when the water level in the recovery tank 20 reaches a predetermined high water level, the high water level detection device 31 is triggered. This allows different detection devices to be triggered when the water level in the recovery tank 20 is too high or too low, facilitating the detection of the water level in the recovery tank 20, controlling the start and stop of the recovery tank pumping device 40, and controlling the water level in the recovery tank 20.

[0035] Advantageously, such as Figure 1 As shown, the recycling tank 20 is also equipped with a recycling tank discharge port 23, and a recycling tank discharge valve 24 is connected to the recycling tank discharge port 23. Specifically, the recycling tank discharge valve 24 can be connected to the drainage system or directly discharged to the ground. This allows the recycling tank discharge valve 24 to be opened when needed to drain the water in the recycling tank 20, for example, when the water supply network 2 has not been used for a long time, resulting in an excessively high water level in the recycling tank 20.

[0036] More advantageously, such as Figure 1 As shown, a recycling tank on / off valve 25 is connected to the outlet 22 of the recycling tank. A water quality detection device 60 is also installed on the recycling tank 20, which is electrically connected to the recycling tank discharge valve 24 and the recycling tank on / off valve 25. This allows the water quality detection device 60 to monitor the water quality in the recycling tank 20. When the water quality is substandard, the recycling tank on / off valve 25 closes and the recycling tank discharge valve 24 opens. This prevents substandard water from entering the municipal water supply network 2 and discharges the substandard water through the recycling tank discharge valve 24. This further facilitates ensuring the quality of the recycled water and improves the reliability of subsequent water use.

[0037] Specifically, the water quality testing device 60 is electrically connected to the recovery tank pumping device 40, and the recovery tank pumping device 40 stops operating when the water quality testing device 60 detects that the water quality is unqualified to prevent the recovery tank pumping device 40 from running dry.

[0038] Optionally, such as Figure 1 As shown, the water quality testing device 60 includes a pH testing device 61 and a turbidity testing device 62. This allows the pH and turbidity of the water in the recovery tank 20 to be detected by the pH testing device 61 and the turbidity testing device 62, respectively. When the pH and turbidity of the water in the recovery tank 20 exceed a predetermined range, the water quality is deemed unqualified, and recovery is stopped promptly by closing the recovery tank on / off valve 25 and opening the recovery tank discharge valve 24.

[0039] More specifically, such as Figure 1 As shown, the filtration device 50 includes a pre-filtration device 51 and a fine filtration device 52. The pre-filtration device 51 is connected between the recovery tank pumping device 40 and the tap water network 2. The fine filtration device 52 is connected between the pre-filtration device 51 and the tap water network 2. Specifically, the pre-filtration device 51 can be a bag filter. In this way, the pre-filtration device 51 first intercepts large particulate impurities in the water, preventing large particulate impurities from clogging or wearing down the subsequent fine filtration device 52, thus reducing the burden on the fine filtration device 52. Then, the fine filtration device 52 further refines the recovered water after the preliminary filtration by the pre-filtration device 51, intercepting even smaller particles, bacteria, and other impurities, making the recovered water purer and achieving a higher water quality standard.

[0040] Furthermore, such as Figure 1 As shown, the fluid food storage tank 10 includes an outer shell 13 and an inner liner 14. The inner liner 14 is suitable for storing fluid food. The inner liner 14 is located inside the outer shell 13, and a cooling water cavity 16 is defined by the outer shell 13 and the inner shell 14. Both the cooling water inlet 11 and the cooling water outlet 12 are connected to the cooling water cavity 16. A spray device 15 is provided above the inner liner 14, and the spray device 15 is connected to the cooling water inlet 11. Specifically, after the cooling water enters the spray device 15 through the cooling water inlet 11, it is sprayed onto the outer surface of the inner liner 14 to cool the inner liner 14, and then discharged through the cooling water outlet 12. This not only achieves spray cooling of the inner liner 14 and facilitates the centralized collection of cooling water, but also avoids contact between the cooling water and the fluid food inside the inner liner 14 or the external environment outside the outer shell 13. On the one hand, it prevents the cooling water from affecting the production process of the fluid food, and on the other hand, it reduces the mixing of impurities in the cooling water, reduces the processing pressure of the filter device 50, and facilitates the recycling of water resources.

[0041] Figure 1 A cooling water recovery system 1 for a fluid food storage tank according to some examples of the present invention is shown. For example... Figure 1As shown, the fluid food storage tank cooling water recovery system 1 also includes a buffer tank 70, the volume of which is smaller than that of the recovery tank 20. The buffer tank 70 is equipped with a buffer tank inlet 71 and a buffer tank outlet 72. The buffer tank inlet 71 is connected to the cooling water outlet 12, and the buffer tank outlet 72 is connected to the recovery tank inlet 21. Since the sterilization and cooling of the fluid food storage tank 10 are intermittent, the buffer tank 70 can buffer and store the water between the fluid food storage tank 10 and the recovery tank 20, making the subsequent water supply more stable and orderly, preventing the pumping device from running dry, and ensuring the stable, efficient, and continuous operation of the fluid food storage tank cooling water recovery system 1.

[0042] Specifically, such as Figure 1 As shown, the buffer tank 70 is equipped with a high water level detection device 73 and a low water level detection device 74. A buffer tank pumping device 75 is connected between the buffer tank outlet 72 and the recovery tank inlet 21. The buffer tank pumping device 75 is electrically connected to both the high water level detection device 73 and the low water level detection device 74. Specifically, the high water level detection device 73 is located above the low water level detection device 74. When the water level in the buffer tank 70 is lower than the low water level, the low water level detection device 74 is triggered and the buffer tank pumping device 75 stops to prevent the pumping device 75 from running dry. When the water level in the buffer tank 70 is higher than the high water level, the high water level detection device 73 is triggered and the pumping device 75 starts to operate to prevent the buffer tank 70 from overflowing. This facilitates the control of the water level in the buffer tank 70 and ensures the stable, efficient, and continuous operation of the fluid food storage tank cooling water recovery system 1.

[0043] More specifically, such as Figure 1 As shown, the buffer tank 70 is also equipped with a buffer tank discharge port 76, which is connected to a buffer tank discharge valve 77. The buffer tank outlet 72 is connected to a buffer tank on / off valve 78. Specifically, the buffer tank discharge port 76 can be connected to a drainage system or directly discharged to the ground. This allows the buffer tank on / off valve 78 to be closed for maintenance or when water recycling is not required, enabling maintenance of downstream equipment. Conversely, the buffer tank discharge valve 77 can be opened to discharge water from the buffer tank 70 when maintenance is required or water recycling is not required.

[0044] Specifically, the discharge port 23 of the recovery tank is located at the bottom of the recovery tank 20 for drainage, and the top of the recovery tank 20 is equipped with a pressure balancing valve 26 to balance the internal and external air pressure during water inflow and outflow. The discharge port 76 of the buffer tank is located at the bottom of the buffer tank 70 for drainage, and the top of the buffer tank 70 is equipped with a pressure balancing valve 79 to balance the internal and external air pressure during water inflow and outflow.

[0045] The cooling water outlet 12 is connected to a tank on / off valve 80. This allows the tank on / off valve 80 to be closed when maintenance is required, facilitating maintenance of downstream equipment.

[0046] The recycling tank 20 can be located in a different workshop from the buffer tank 70 to facilitate centralized storage of recycled water.

[0047] Other components and operations of the fluid food storage tank cooling water recovery system 1 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
