[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figure 1 This invention describes the online cleaning system.

[0020] In some embodiments, such as Figure 1 As shown, this utility model provides an online cleaning system, including: a solution adding pipeline 1, a first balancing tank 2, a static mixer 3, a first switching pipeline 4, and a soft water adding pipeline 5. The solution adding pipeline 1 is used to add a solution for cleaning the sterilization device 100; the first balancing tank 2 is configured to be connected to the sterilization device 100; the static mixer 3 is configured to be connected to the sterilization device 100; the first switching pipeline 4 is connected to the solution adding pipeline 1, the first balancing tank 2, and the static mixer 3 respectively, and is used to control the solution adding pipeline 1 to selectively supply solution to the first balancing tank 2 or the static mixer 3, or to control the first balancing tank 2 to supply solution to the static mixer 3; the soft water adding pipeline 5 is connected to the static mixer 3 and is used to add soft water to the static mixer 3.

[0021] Understandably, when cleaning the sterilization device 100, the cleaning solution (usually one of acid, alkali or disinfectant) needs to be mixed and diluted with soft water to form a cleaning solution. The cleaning solution is then circulated into the circulation pipeline of the sterilization device 100 to clean the circulation pipeline of the sterilization device 100.

[0022] In this embodiment, the solution addition pipeline 1 is used to supply the cleaning solution (usually one of acid, alkali or disinfectant), and the soft water addition pipeline 5 is used to supply soft water for diluting the solution to the static mixer 3. The first switching pipeline 4 is connected to the solution addition pipeline 1, the first balance tank 2 and the static mixer 3 respectively. It can be understood that the first switching pipeline 4 includes multiple branches and control valve groups. Through the cooperation of the control valve groups and the corresponding branches, the flow direction of the solution supplied by the solution addition pipeline 1 is controlled, thereby realizing the switching of the cleaning mode of the online cleaning system.

[0023] Specifically, in the first cleaning mode, soft water from the soft water addition pipeline 5 can be directly introduced into the sterilization device 100 through the static mixer 3, or it can be supplied to the sterilization device 100 through its own water supply pipeline. Simultaneously, the valve group on the first switching pipeline 4 closes the branch between the first balance tank 2 and the static mixer 3, and between the solution addition pipeline 1 and the static mixer 3, allowing the solution in the solution addition pipeline 1 to be directly introduced into the sterilization device 100 through the first balance tank 2. This allows the solution and soft water to be directly mixed, diluted, and circulated in the circulation pipeline of the sterilization device 100, thus cleaning the circulation pipeline of the sterilization device 100. It is understood that the static mixer 3 and the first balance tank 2 can be used to quantitatively control the soft water and solution introduced into the sterilization device 100, respectively.

[0024] In the second cleaning mode, soft water from the soft water addition pipe 5 is introduced into the static mixer 3. Simultaneously, the first switching pipe 4 controls the solution addition pipe 1 to directly supply solution into the static mixer 3. The solution and soft water are mixed evenly and diluted in the static mixer 3 to form a cleaning solution, which is then introduced into the sterilization device 100. It can be understood that, compared to the cleaning method of separately introducing soft water and solution into the sterilization device 100 for mixing and cleaning the pipes, this mode introduces a pre-mixed and diluted cleaning solution into the sterilization device 100. There is no need for mixing and dilution within the circulation pipes of the sterilization device 100, resulting in fewer circulations within the sterilization device 100, shorter cleaning time, and less risk of corrosion damage to the internal pipes of the sterilization device 100.

[0025] In the third cleaning mode, soft water from the soft water addition pipeline 5 is introduced into the static mixer 3; the first switching pipeline 4 controls the solution addition pipeline 1 to supply solution to the first balance tank 2, which then quantitatively introduces the solution into the static mixer 3. The solution and soft water are mixed evenly and diluted in the static mixer 3 to form a cleaning solution, which is then introduced into the sterilization device 100. This mode is suitable for scenarios requiring precise control of the ratio of solution to soft water in the cleaning solution (especially suitable for scenarios where the solution content in the cleaning solution is low). Similar to the second cleaning mode, in this mode, the cleaning solution does not need to be mixed and diluted in the circulation pipeline of the sterilization device 100, and the residence time within the sterilization device 100 minimizes damage to the internal pipelines of the sterilization device 100.

[0026] The online cleaning system of this invention includes a solution addition pipeline 1 for supplying a cleaning solution (usually an acid, alkali, or disinfectant), and a soft water addition pipeline 5 for supplying soft water for diluting the solution to a static mixer 3. By setting a first switching pipeline 4 between the solution addition pipeline 1, the first balance tank 2, and the static mixer 3, the first switching pipeline 4 can control the flow path of the solution supplied by the solution addition pipeline 1, thereby controlling the online cleaning system to switch between three different cleaning modes. This allows operators to select the appropriate cleaning mode according to actual working conditions and needs, effectively solving the problem that the existing pasteurization system has a single cleaning mode and cannot be applied to different cleaning scenarios.

[0027] Specifically, in some embodiments, such as Figure 1 As shown, the first switching pipeline 4 includes: a first three-way valve 41 and a switching branch 42; the first three-way valve 41 has a first inlet 411, a first outlet 412 and a second outlet 413; the first inlet 411 is connected to the solution addition pipeline 1; the second outlet 413 is connected to the first balance tank 2; the switching branch 42 is connected to the first outlet 412, the static mixer 3 and the first balance tank 2 respectively, and the switching branch 42 is used to control the static mixer 3 to selectively receive the solution supplied by the first outlet 412 or the first balance tank 2.

[0028] In this embodiment, it can be understood that the first three-way valve 41 can switch the connection between the first inlet 411, the first outlet 412, and the second outlet 413. In the first cleaning mode and the third cleaning mode, the first three-way valve 41 can control the connection between the first inlet 411 and the second outlet 413 so that the solution supplied by the solution addition pipeline 1 is first introduced into the first balance tank 2. In the second cleaning mode, the first three-way valve 41 controls the connection between the first inlet 411 and the first outlet 412 so that the solution supplied by the solution addition pipeline 1 is introduced into the static mixer 3.

[0029] The switching branch 42 is located between the first drain port 412, the static mixer 3, and the first balance tank 2 to adjust the connection method of the first drain port 412, the static mixer 3, and the first balance tank 2 according to the required cleaning mode. Specifically, in the second cleaning mode, the switching branch 42 controls the solution supplied by the first drain port 412 to be directly fed into the static mixer 3; in the third cleaning mode, the switching branch 42 controls the static mixer 3 to only receive containers from the first balance tank 2.

[0030] Specifically, in some embodiments, such as Figure 1As shown, the switching branch 42 includes: a second three-way valve 421, which has a second inlet 4211, a third inlet 4212 and a fourth outlet 4213. The second inlet 4211 is connected to the first outlet 412; the third inlet 4212 is connected to the first balance tank 2; and the fourth outlet 4213 is connected to the static mixer 3.

[0031] In this embodiment, the second three-way valve 421 can switch the connection status of the second inlet 4211, the third inlet 4212, and the fourth outlet 4213 according to the cleaning mode. In the second cleaning mode, the second inlet 4211 and the fourth outlet 4213 are connected so that the solution can be introduced from the first outlet 412 of the first three-way valve 41 into the static mixer 3 through the second three-way valve 421. In the third cleaning mode, the third inlet 4212 and the fourth outlet 4213 are connected so that the solution can be introduced from the first balance tank 2 into the static mixer 3 through the second three-way valve 421.

[0032] In some embodiments, such as Figure 1 As shown, a diaphragm pump 422 is installed between the first balance tank 2 and the third inlet 4212.

[0033] In this embodiment, a diaphragm pump 422 is installed on the pipeline between the first balance tank 2 and the third inlet 4212. The diaphragm pump 422 can provide driving force for the solution in the first balance tank 2, pump the solution into the third inlet 4212, and then into the static mixer 3 through the second three-way valve 421. This avoids the situation where the soft water pressure in the static mixer 3 is too high in the third cleaning mode, which would prevent the solution from entering the static mixer 3.

[0034] In some embodiments, such as Figure 1 As shown, the static mixer 3 has a fourth liquid inlet, a fifth liquid inlet, and a fifth liquid outlet; the fourth liquid inlet is connected to the soft water addition pipeline 5, the fifth liquid inlet is connected to the fourth liquid outlet 4213, and the fifth liquid outlet is connected to the sterilization device 100.

[0035] In this embodiment, the fourth inlet of the static mixer 3 is used to receive soft water supplied by the soft water addition pipeline 5, and the fifth inlet is connected to the fourth outlet 4213 of the second three-way valve 421 to receive the solution introduced by the second three-way valve 421. It can be understood that the solution introduced by the second three-way valve 421 can come directly from the first three-way valve 41 or from the first balance tank 2. The design of the second three-way valve 421 allows the static mixer 3 to have only one inlet for introducing the solution, simplifying its structure. The fifth outlet is used to introduce the cleaning solution mixed in the static mixer 3 into the sterilization device 100.

[0036] In some embodiments, such as Figure 1 As shown, the online cleaning system also includes a second switching pipeline 6, which is configured to be connected to the fifth drain port, the second balance tank 101 of the sterilization device 100 and the sterilization section 102 of the sterilization device 100, respectively. The second switching pipeline 6 is used to control the static mixer 3 to selectively supply cleaning fluid to the second balance tank 101 or the sterilization section 102.

[0037] Understandably, the second balancing tank 101 of the sterilization device 100 is used to receive the raw milk that has not yet been sterilized. Its main functions are to stabilize the flow rate of the raw milk, eliminate air bubbles in the raw milk, and ensure the stability of the sterilization temperature. The raw milk is then introduced into the sterilization section 102 located downstream of the second balancing tank 101 for sterilization. The sterilization section 102 typically includes pipe sections for supplying the raw milk for flow and sterilization. The sterilization device 100 usually includes heat exchangers and other devices in the sterilization section 102 for heating and sterilizing the raw milk.

[0038] In this embodiment, a second switching pipeline 6 is provided between the static mixer 3, the second balance tank 101 of the sterilization device 100, and the sterilization section 102 of the sterilization device 100. The second switching pipeline 6 can control the flow direction of the soft water or the mixed cleaning liquid in the static mixer 3 through its own valve group, so that the operator can pass the soft water or the mixed cleaning liquid in the static mixer 3 into the second balance tank 101 and the sterilization section 102 of the sterilization device 100 according to the cleaning requirements.

[0039] In one specific embodiment, the second switching pipeline 6 further includes a third three-way valve 61, which has a fifth inlet, a sixth outlet and a seventh outlet; the fifth inlet is connected to the fifth outlet, the sixth outlet is connected to the second balance tank 101, and the seventh outlet is connected to the sterilization section 102.

[0040] In this embodiment, the fifth inlet of the third three-way valve 61 is used to receive the cleaning liquid or soft water introduced into the static mixer 3, and the connection status of the fifth inlet, the sixth outlet, and the seventh outlet is switched according to the cleaning requirements. When the fifth inlet and the sixth outlet are connected, the soft water or cleaning liquid in the static mixer 3 can be introduced into the second balance tank 101. When the fifth inlet and the seventh outlet are connected, the soft water or cleaning liquid in the static mixer 3 can be introduced into the sterilization section 102.

[0041] Optionally, in one specific embodiment, such as Figure 1 As shown, the soft water addition pipeline 5 includes a first soft water pipeline and a second soft water pipeline. The first soft water pipeline is connected to the static mixer 3, and the second soft water pipeline is connected to the second balance tank 101.

[0042] In one specific embodiment, in the first cleaning mode, the flow path of the cleaning solution is as follows: solution addition pipeline 1 - first three-way valve 41 - first balancing tank 2 - second balancing tank 101; the flow path of the soft water is as follows: second soft water pipeline - second balancing tank 101 or first soft water pipeline - static mixer 3 - third three-way valve 61 - second balancing tank 101. The soft water and solution are mixed and diluted in the second balancing tank 101 and subsequent pipelines.

[0043] In the second cleaning mode, the flow path of the cleaning solution is as follows: solution addition pipeline 1 - first three-way valve 41 - second three-way valve 421 - static mixer 3; the flow path of the soft water is as follows: first soft water pipeline - static mixer 3. The soft water and solution are mixed and diluted in the static mixer 3 to form a cleaning solution, which is then directly introduced into the sterilization section 102 through the third three-way valve 61.

[0044] In the third cleaning mode, the flow path of the cleaning solution is as follows: solution addition pipeline 1 - first three-way valve 41 - first balance tank 2 - second three-way valve 421 - static mixer 3; the flow path of the soft water is as follows: first soft water pipeline - static mixer 3. The soft water and solution are mixed and diluted in the static mixer 3 to form a cleaning solution, which is then directly introduced into the sterilization section 102 through the third three-way valve 61.

[0045] In some embodiments, such as Figure 1 As shown, an air drain valve 21 is provided between the first balance tank 2 and the sterilization device 100. The air drain valve 21 is used to drain the solution in the first balance tank 2.

[0046] It is understandable that the drain valve 21 is installed on the branch pipe of the pipeline between the first balance tank 2 and the sterilization device 100. The drain valve 21 is used to discharge the residual solution in the first balance tank 2 after cleaning.

[0047] Specifically, in some embodiments, the solution addition line 1 includes at least one of an acid addition line 11, an alkali addition line 12, and a disinfectant addition line 13. The acid addition line 11 is used to supply a high-concentration acid (such as nitric acid, hydrochloric acid, etc.), the alkali addition line 12 is used to supply a high-concentration alkali (such as sodium hydroxide, potassium hydroxide, etc.), and the disinfectant addition line 13 is used to supply a high-concentration disinfectant (such as peracetic acid, sodium hypochlorite, etc.). All three solutions can be mixed and diluted with soft water to form a cleaning solution for cleaning the internal pipes of the sterilization device 100.

[0048] In one specific embodiment, the acid addition pipeline 11, the alkali addition pipeline 12, and the disinfectant addition pipeline 13 are all connected to the first inlet 411 of the first three-way valve 41 via a main pipe. Control valves are respectively installed on the acid addition pipeline 11, the alkali addition pipeline 12, the disinfectant addition pipeline 13, and the main pipe to control the flow of solutions within these pipelines. This allows operators to selectively mix one of the acid, alkali, or disinfectant solutions with soft water to clean the sterilization device 100 according to cleaning needs.

[0049] Secondly, this utility model also provides a sterilization system, including: a sterilization device 100 and an online cleaning system provided in any of the above embodiments. The sterilization device 100 is connected to a static mixer 3 and a first switching pipeline 4.

[0050] The sterilization system of this invention also has the advantages of the online cleaning system described in the above embodiments, which will not be repeated here.

[0051] Specifically, the sterilization device 100 includes at least a second balancing tank 101 and a sterilization section 102. The second balancing tank 101 has multiple liquid inlets, some of which are used to receive raw milk to be sterilized and to introduce the raw milk into the sterilization section 102 for heating and sterilization. The remaining liquid inlets are respectively used to connect to the first balancing tank 2, the static mixer 3, and the soft water addition pipeline 5. Optionally, the sterilization section 102 may also be connected to the static mixer 3.

[0052] Optionally, the sterilization system of this invention can be a pasteurization system, an ultra-high temperature sterilization system, or other dairy sterilization systems.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
