[0032] 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.

[0033] The following is combined Figures 1-2 The present invention describes a hydrogen peroxide addition and filling system, comprising a hydrogen peroxide addition device 100, a filling unit 200, an automatic water supply circuit 300, an automatic water filling circuit 400, and a first early warning device 610. The hydrogen peroxide addition device 100 includes a hydrogen peroxide tank 110, which has a high level switch 111 and a low level switch 112. The filling unit 200 includes at least one filling machine 210, and the outlet of the hydrogen peroxide tank 110 is higher than the inlet of the filling machine 210. The automatic water supply circuit 300 is used to connect to the hydrogen peroxide source. The outlet of the automatic water supply circuit 300 is connected to the inlet of the hydrogen peroxide tank 110. The inlet of the filling machine 210 and the outlet of the hydrogen peroxide tank 110 are connected through the automatic water filling circuit 400. The automatic water filling circuit 400 is equipped with an automatic control valve group 500. The automatic control valve group 500 is used to control the water flow between the filling machine 210 and the hydrogen peroxide tank 110. The first early warning device 610 is electrically connected to the low liquid level switch 112.

[0034] This utility model provides a hydrogen peroxide addition and filling system. Compared with the existing method of adding hydrogen peroxide in small barrels, this utility model is equipped with a high liquid level switch 111 and a low liquid level switch 112. When the liquid level is low, the first warning device 610 automatically alarms and automatically replenishes hydrogen peroxide to the hydrogen peroxide tank 110 through the automatic water supply circuit 300, eliminating the need for frequent manual intervention. By setting the hydrogen peroxide tank 110 at a high position, when the filling machine 210 needs hydrogen peroxide, the hydrogen peroxide tank 110 and the automatic control valve group 500 open, and the hydrogen peroxide tank 110 adds hydrogen peroxide to the filling machine 210 to the required liquid level through gravity flow from the high position. This ensures a stable supply of hydrogen peroxide, automatic liquid level control, and more stable and efficient operation.

[0035] It should be noted that, referring to Figure 1 In this embodiment of the invention, the automatic water supply circuit 300 is connected to the externally purchased hydrogen peroxide source tank A, and the automatic water supply circuit 300 is equipped with a first delivery pump to deliver the hydrogen peroxide. When the hydrogen peroxide tank 110 is at a low liquid level, the first warning device 610 automatically alarms, and the first delivery pump automatically adds hydrogen peroxide to the hydrogen peroxide tank 110.

[0036] Understandably, referring to Figure 1In this embodiment of the utility model, the hydrogen peroxide addition and filling system also includes a control cabinet 840 and a touch screen 850. The control cabinet 840 is equipped with a PLC controller, and the touch screen 850 is located on one side of the control cabinet 840 and is electrically connected to the PLC controller to realize automatic control. At the same time, the system operation data can be uploaded in real time.

[0037] Reference Figure 1 In this embodiment, the first early warning device 610 is located on the top of the touch screen 850, and the top of the control cabinet 840 is provided with a second early warning device 620. The second early warning device 620 is used to monitor the operating status of the control components inside the control cabinet 840.

[0038] Understandably, referring to Figure 1 and Figure 2 In this embodiment of the utility model, the hydrogen peroxide adding device 100 further includes a weighing device 120, which is located on one side of the hydrogen peroxide tank 110 and is used to weigh the liquid in the hydrogen peroxide tank 110.

[0039] It should be noted that in this embodiment, the weighing device 120 is a weighing sensor, and the first warning device 610 and the second warning device 620 are both buzzers.

[0040] In this embodiment, the hydrogen peroxide tank 110 has a maximum capacity of 1500KG. When the weighing device 120 detects a low liquid level of less than 100KG, the first warning device 610 (i.e., the buzzer) will activate, and the first delivery pump will deliver hydrogen peroxide to the hydrogen peroxide tank 110 until it reaches 1300KG before stopping the addition. Therefore, the weighing device 120 further improves the measurement accuracy, realizes automated and intelligent management, and enhances operational safety.

[0041] Understandably, referring to Figure 1 and Figure 2 In this embodiment of the utility model, the automatic water filling path 400 includes a main water path 410 and multiple branch water paths 420, all of which are connected to the main water path 410; there are multiple filling machines 210, and each of the multiple filling machines 210 is connected to one of the multiple branch water paths 420.

[0042] Specifically, in this embodiment, the main waterway 410 has two branches, and each branch has multiple branch waterways 420. Of course, the main waterway 410 may also have only one branch or multiple branches, which is not limited here.

[0043] With the above structure, multiple filling machines 210 can be centrally and uniformly added through the same hydrogen peroxide tank 110. The main water channel 410 delivers hydrogen peroxide to each branch water channel 420, and then to the hydrogen peroxide supply channel connected to the water inlet of the filling machine 210, before entering the filling machine 210. This solves the instability of hydrogen peroxide addition during the existing operation, optimizes the addition mode, and adds hydrogen peroxide in a large tank, achieving uniformity in the addition of hydrogen peroxide to the filling machine 210. At the same time, hydrogen peroxide is not stored in the filling room, integrating process resource waste, reducing storage in the process workshop and personnel contact, and one system can centrally supply hydrogen peroxide to multiple filling machines 210.

[0044] It should be noted that, referring to Figure 1 In this practical embodiment, the filling machine 210 retains its own manual addition mode. This can be understood as the filling machine 210 retaining its own hydrogen peroxide tank 211 and its own solenoid valve 212. It can be manually switched between the filling machine 210 and the automatic centralized hydrogen peroxide addition filling system, which enhances fault tolerance and improves operational flexibility.

[0045] It should also be understood that the ratio of the flow diameters of the main waterway 410 and the branch waterway 420 can be set as needed, and can be selected as 63 to 25, without limitation.

[0046] Understandably, referring to Figure 1 In this novel embodiment, the automatic control valve group 500 includes two sets of automatic valve modules 510, which are sequentially and spaced apart on the automatic water filling circuit 400. It can be understood that each automatic valve module 510 includes a solenoid valve, a manual shut-off valve, and an automatic shut-off valve arranged sequentially from left to right. Compressed air flows sequentially through the solenoid valve, the manual shut-off valve, and the automatic shut-off valve, and the automatic shut-off valve is connected to the branch water circuit 420.

[0047] With the above setup, during the production process, the low liquid level signal from the filling machine 210 sends a signal to the PLC controller of the filling system. When the system is ready, the system control turns on. If there is an abnormality in the system or the automatic shut-off valve is not working during the cleaning process, the filling machine 210 control signal will turn on but hydrogen peroxide cannot be added. When the system is normal, the two automatic shut-off valves open, and the hydrogen peroxide in the tank flows downward by gravity to the required liquid level of the filling machine 210. Through this design, the flexibility, safety, and efficiency of the water supply system can be significantly improved.

[0048] It should be noted that in this embodiment, the branch water passage 420 is also equipped with two manual shut-off valves. These two manual shut-off valves are located on either side of the automatic shut-off valve; one manual shut-off valve is located on one side of the inlet end of the automatic shut-off valve, and the other is located on the other side of the outlet end. This allows for rapid control in case of malfunction of the automatic shut-off valve. It should be understood that during system operation, the manual shut-off valves are in a closed state and do not operate, allowing liquid to pass through them and be delivered to the inlet end of the automatic shut-off valve for automatic control. The operating states of other automatic and manual valve components are based on the above description and will not be elaborated upon here.

[0049] Of course, in some embodiments, the automatic control valve group 500 includes a set of automatic valve modules 510, and the automatic valve modules 510 can be selected to adapt to the valve type as needed. For example, a manual shut-off valve can be replaced with a manual two-way ball valve, and an automatic shut-off valve can be replaced with an automatic two-way ball valve.

[0050] It should be noted that, referring to Figure 1 In this embodiment of the utility model, the end of the automatic water filling circuit 400 is provided with a discharge valve group. Specifically, the discharge valve group includes an automatic discharge valve 730 module and a manual discharge valve 720. That is, the end of the water supply pipeline is provided with a manual discharge valve 720 and an automatic discharge valve 730 module from top to bottom. The automatic discharge valve 730 module includes a solenoid valve, a manual shut-off valve and an automatic shut-off valve arranged from left to right. The above arrangement not only facilitates the discharge of hydrogen peroxide in the pipeline, but also the combination of the manual discharge valve 720 and the automatic discharge valve 730 module can prevent abnormal discharge of the system.

[0051] Specifically, refer to Figure 1 In this embodiment of the utility model, a hydrogen peroxide concentration meter 710 is installed on the automatic water filling circuit 400, which can monitor the concentration of hydrogen peroxide in the water in real time, respond quickly to changes in water quality, and improve water treatment efficiency.

[0052] Understandably, referring to Figure 1 In this embodiment of the utility model, the hydrogen peroxide adding device 100 further includes a support platform 130, and the hydrogen peroxide tank 110 is located on the upper part of the support platform 130; the hydrogen peroxide adding and filling system further includes a first drainage channel 810, which is arranged along the height direction of the support platform 130; the bottom of the hydrogen peroxide tank 110 is provided with a drain outlet, which is connected to the first drainage channel 810, and the first drainage channel 810 is provided with a ground drain valve assembly.

[0053] Specifically, refer to Figure 1In this embodiment, the drain valve assembly includes a first manual drain valve and an automatic drain valve arranged sequentially from top to bottom along the height direction of the first drain path 810. The inlet of the manual drain valve is connected to the drain outlet, and the outlet of the manual drain valve is connected to the inlet of the automatic drain valve, which can effectively control the discharge of liquid in the tank and ensure stable operation and efficient work. It is understood that, in this embodiment, in order to make full use of space, the first drain path 810 can be arranged through the support platform 130.

[0054] Specifically, refer to Figure 1 In this embodiment, the support platform 130 is also provided with a second drainage channel 820, and a second manual drain valve is provided on the second drainage channel 820. When a pipeline leak is detected, the second manual drain valve is opened to drain the liquid present in the support platform 130, so as to facilitate pipeline maintenance.

[0055] It should be noted that the cleaning structure 113 mentioned above can be a spray structure, an ultrasonic cleaning structure 113, etc., and is not limited here.

[0056] It is understood that in this embodiment, the hydrogen peroxide tank 110 is also equipped with a breather valve and a gas control valve for introducing compressed air. After the hydrogen peroxide cleaning is completed, compressed air is introduced into the tank through the gas control valve to purge the inside of the tank.

[0057] Specifically, in this embodiment, the hydrogen peroxide addition and filling system further includes a first cleaning water path for introducing cleaning fluid; the hydrogen peroxide tank 110 is provided with a cleaning structure 113 for cleaning the interior of the hydrogen peroxide tank 110, and the first cleaning water path is connected to the water inlet of the cleaning structure 113. The cleaning structure 113 cleans the inner wall of the hydrogen peroxide tank 110, preventing dirt and microorganisms from adhering to the tank wall and ensuring the safety of the supplied water quality. It is understood that the first cleaning water path connects to the factory's CIP (Clean In-Place) room, and is equipped with a sanitary check valve and a second delivery pump. When cleaning is selected, all automatic valve components entering the filling machine 210 automatically close, and can be restored to automatic and manual states after cleaning.

[0059] With the above configuration, in this embodiment, the second cleaning water path is connected to the main water path 410, enters the branch water path 420 along the main water path 410, and then enters the filling machine 210 through the hydrogen peroxide supply water path 910. This can clean the automatic water filling path 400 and the filling machine 210, ensuring the safety of the water supply quality. It can be understood that the second cleaning water path is connected to the factory's CIP (Cleaning in Place) room.
