[0026] In order to make the purpose, technical solution and beneficial technical effect of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for explaining the utility model, and are not intended to limit the utility model.

[0027] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0028] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0029] In an embodiment of the utility model, a sterilizing kettle heat energy recovery mechanism 100 is provided, which is used to recover the heat energy in the 105°C hot water after the sterilization of the sterilizing kettle, and the heat energy can be injected into the sterilizing kettle again for use during the next sterilization, or pumped into the boiler water tank as boiler water, or as equipment cleaning water, thereby improving energy utilization.

[0030] like Figure 1 As shown, the sterilizing kettle heat energy recovery mechanism 100 includes: a heat exchanger 10, a sterilizing kettle 20, a softening cold water tank 30, and a softening hot water tank 40.

[0031] The heat exchanger 10 includes a first pipeline and a second pipeline (not shown in the figure) for heat exchange. The sterilizer 20 is connected to the first pipeline; the softened cold water tank 30 is connected to one end of the second pipeline. The softened hot water tank 40 is connected to the end of the second pipeline away from the softened cold water tank 30, and the end of the softened hot water tank 40 away from the heat exchanger 10 is connected to the sterilizer 20.

[0032] Specifically, the liquid flows in the first pipeline and the second pipeline are arranged in opposite directions, and reverse heat exchange can be performed to improve the heat exchange efficiency. The high-temperature hot water in the sterilizer 20 circulates through the first pipeline, and the softened cold water in the softened cold water tank 30 passes through the second pipeline and exchanges heat with the high-temperature hot water in the first pipeline to obtain higher-temperature softened hot water, which is then stored in the softened hot water tank 40. It can be injected into the sterilizer 20 again for use during the next sterilization, so that the hot water in the sterilizer 20 can be heated to 105°C with less heat, saving energy; the softened hot water can also be pumped into the boiler water tank as boiler water or as equipment cleaning water for reuse, improving energy utilization.

[0033] In this embodiment, the two ends of the first pipeline are defined as the first interface 11 and the second interface 12 respectively. The sterilizing kettle 20 is connected to the first interface 11 through the first branch 1, and is connected to the second interface 12 through the second branch 2, so as to form a loop for circulating high-temperature hot water. Among them, the second branch 2 is provided with a circulation drive pump 21, which is used to drive the high-temperature hot water in the sterilizing kettle 20 to pass through the first branch 1, the first pipeline, and the second branch 2 in sequence and then enter the sterilizing kettle 20 again.

[0034] Furthermore, in the embodiment of the utility model, the heat recovery mechanism 100 of the sterilizing kettle also includes a cooling water component 50. It can be understood that after the high-temperature hot water in the sterilizing kettle 20 is softened by cold water for heat recovery, the water in the sterilizing kettle 20 still has a certain temperature (for example, several tens of degrees Celsius), and at this time, it can be further cooled by the cooling water component 50 so that the water temperature in the sterilizing kettle 20 meets the requirements.

[0035] Specifically, the two ends of the second pipeline are defined as the third interface 13 and the fourth interface 14, respectively. The cooling water assembly 50 is connected to the third interface 13 through the third branch 3, and is connected to the fourth interface 14 through the fourth branch 4, thereby forming a loop for cooling water to flow. Among them, the fourth branch 4 is provided with a cooling water drive pump 41, and the cooling water drive pump 41 is used to drive the cooling water in the cooling water assembly 50 to pass through the third branch 3, the second pipeline, and the fourth branch 4 in sequence and then enter the cooling water assembly 50 again. That is, the cooling water can exchange heat with the higher temperature water in the first pipeline through the second pipeline.

[0036] In this embodiment, the third branch 3 is provided with a first valve 101 and a second valve 102 which are arranged at intervals. The fourth branch 4 is provided with a third valve 103 and a fourth valve 104 which are arranged at intervals. The softened cold water tank 30 is connected to the third branch 3 through the fifth branch 5, and the connection position is located between the first valve 101 and the second valve 102. The softened hot water tank 40 is connected to the fourth branch 4 through the sixth branch 6, and the connection position is located between the third valve 103 and the fourth valve 104. The fifth branch 5 is provided with a fifth valve 105, and the sixth branch 6 is provided with a sixth valve 106. That is, the fifth branch 5 and the third branch 3 have part of the pipeline structure reused as one, and the sixth branch 6 and the fourth branch 4 have part of the pipeline structure reused as one. Specifically, these reused pipeline structures are usually located on both sides of the heat exchanger 10.

[0037] When the softened cold water and the high-temperature hot water (hot water at about 105°C) in the sterilizing kettle 20 are used for heat recovery, the first valve 101 and the third valve 103 are closed, and the second valve 102, the fourth valve 104, the fifth valve 105, and the sixth valve 106 are opened; when cooling water is needed to further cool the higher-temperature hot water after heat energy recovery in the sterilizing kettle 20, the fifth valve 105 and the sixth valve 106 are closed, and the first valve 101, the second valve 102, the third valve 103, and the fourth valve 104 are opened.

[0038] In this embodiment, the softened hot water tank 40 is connected to the second branch 2 through the seventh branch 7, so that the softened hot water in the softened hot water tank 40 can be injected into the sterilizer 20 for use during the next sterilization, so that the hot water in the sterilizer 20 can be heated to 105°C with less heat, thereby saving energy. Among them, the seventh branch 7 is provided with a softened hot water drive pump 71, a first check valve 72 and a seventh valve 107. The first check valve 72 controls the softened hot water to flow only from the softened hot water tank 40 to the sterilizer 20, or to flow outward. The softened hot water drive pump 71 is used to pump the softened hot water in the softened hot water tank 40 into the sterilizer 20.

[0039] Furthermore, the fifth branch 5 is also provided with a softened cold water driving pump 51, a second one-way valve 52, and an eighth valve 108. The second one-way valve 52 controls the softened cold water to flow only from the softened cold water tank 30 to the heat exchanger 10. The softened cold water driving pump 51 is used to pump the softened cold water in the softened cold water tank 30 into the heat exchanger 10.

[0040] The fifth branch 5 is connected to the seventh branch 7 through the eighth branch 8. Specifically, the connection position between the fifth branch 5 and the eighth branch 8 is between the eighth valve 108 and the fifth valve 105, and the connection position between the seventh branch 7 and the eighth branch 8 is between the first check valve 72 and the seventh valve 107. That is, the softened cold water in the softened cold water tank 30 can also directly enter the sterilizing kettle 20 through the softened cold water driving pump 51, the eighth valve 108, the eighth branch 8, and the seventh valve 107 in sequence, without passing through the softened hot water tank 40 and this section of the pipeline, to meet the needs in some special circumstances. At this time, the softened cold water pumped into the sterilizing kettle 20 is softened cold water. The eighth branch 8 is provided with a ninth valve 109, which is used to control the on and off of the eighth branch 8.

[0041] Furthermore, the softened cold water tank 30 is connected to the ion exchanger 60 through the ninth branch 9. The ion exchanger 60 is used to convert tap water into softened water and send it into the softened cold water tank 30 through the ninth branch 9. Its specific structure and implementation principle can refer to the prior art, and the utility model will not repeat them here. The ninth branch 9 is provided with a tenth valve 110, which is used to control the on and off of the ninth branch 9.

[0042] To summarize, the sterilizer heat energy recovery mechanism 100 provided by the utility model connects the hot water in the sterilizer 20 with the first pipeline of the heat exchanger 10 and connects the softened cold water tank 30 with the second pipeline, so that the heat energy of the high-temperature hot water in the sterilizer 20 can be exchanged to the softened cold water flowing out of the softened cold water tank 30 in the heat exchanger 10, and transported to the softened hot water tank 40 for storage, which can be injected into the sterilizer 20 for use during the next sterilization, or pumped into the boiler water tank as boiler water, or as equipment cleaning water, thereby improving energy utilization.

[0043] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
