Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen peroxide reflux monitoring for filling machines, in particular to a hydrogen peroxide reflux monitoring and alarm device for filling machines. Background Art

[0002] During the normal production process of the filling machine, the hydrogen peroxide in the hydrogen peroxide tank is driven by the hydrogen peroxide pump through the pipeline into the hydrogen peroxide immersion tank, and then flows into the hydrogen peroxide tank through the overflow pipe hole at the high liquid level of the immersion tank through the return pipe, thus circulating. The corresponding structure refers to Figure 1 The hydrogen peroxide in the soaking box sterilizes and disinfects the packaging materials that pass through the soaking box during production to ensure product quality.

[0003] However, during the reflux process of hydrogen peroxide, the hydrogen peroxide pump may malfunction, the impeller may become stuck due to foreign matter, or the overflow valve of the hydrogen peroxide pipe above the pump may be opened too wide by mistake. As a result, the hydrogen peroxide cannot complete the reflux cycle or most of the flow flows directly out of the overflow valve and back to the hydrogen peroxide tank without entering the immersion tank, affecting the sterilization effect of the packaging material.

[0004] In a production line assembled in the conventional way, the filling machine and hydrogen peroxide tank will not issue an alarm when hydrogen peroxide does not flow back during the production process. If the staff does not discover this abnormality in time, continued production will pose a serious hidden danger to product quality. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Example 1, a hydrogen peroxide backflow monitoring and alarm device for a filling machine, the structure of which is referenced Figure 1-2 , as shown in 4-6.

[0025] The application scenario of this embodiment device is in the connection system between the filling machine and the hydrogen peroxide tank, the connection system between the filling machine and the hydrogen peroxide tank, such as Figure 1 As shown, the apparatus includes a vertically arranged hydrogen peroxide return pipe 4. This embodiment replaces a section of the hydrogen peroxide return pipe 4. The apparatus comprises a probe mounting tube 12 disposed on the sidewall of the hydrogen peroxide return pipe 4. A liquid level probe 1 is mounted within the probe mounting tube 12, with its tip extending into the hydrogen peroxide return pipe 4. The liquid level probe 1 is electrically connected to an alarm 11.

[0026] An insulating sleeve 3 is provided between the liquid level probe 1 and the probe mounting tube 12. The insulating sleeve 3 is used to protect the liquid level probe 1.

[0027] The hydrogen peroxide return pipe 4 is screwed with a positioning bolt 5; the tail of the liquid level probe 1 is screwed with a nut 2. After the liquid level probe 1 is placed in the hydrogen peroxide return pipe 4, it can be installed with the nut 2 and fixed with the positioning bolt 5.

[0028] The liquid level probe 1 is connected to the liquid level relay 6 through wires, the liquid level relay 6 is connected to the intermediate relay 7, the power module 10, the alarm 11 and the L live wire and the N neutral wire respectively through wires, the intermediate relay 7 is connected to the PLC 8, the power module 10 and the L live wire and the N neutral wire respectively through wires, the power module 10 is connected to the alarm 11 through wires, and the PLC 8 is connected to the switch 9 through wires.

[0029] The alarm 11 is a buzzer alarm.

[0030] To implement the aforementioned hydrogen peroxide backflow monitoring and alarm device for a filling machine, the live wire of the 220V AC power supply is closed, energizing the coil of the liquid level relay 6. The second set of normally open contacts of the intermediate relay 7 is connected to the negative 24V terminal of the DC power supply module 10. When the intermediate relay 7 is operating, the closure of the second set of contacts connects the negative terminal of the buzzer alarm 11 mounted on top of the filling machine 1. The normally closed contact of the liquid level relay 6 is connected to the positive 24V DC power supply, the output point is connected to the buzzer alarm 11, and the other terminal is connected to the negative terminal of the 24V DC power supply of the second set of normally open output points of the intermediate relay 7. The liquid level relay 6 has two signal terminals connected to the two poles of the liquid level probe 1: one electrode is connected to the tail of the liquid level probe 1, and the other electrode is connected to the metal wall of the liquid level probe 1. Liquid level probe 1 is installed on hydrogen peroxide reflux pipe 4. When hydrogen peroxide refluxes, liquid level probe 1 detects liquid and generates a signal. The coil of liquid level relay 6 activates, the 24V normally closed terminal of DC power supply module 10 is disconnected, and the 24V power of buzzer alarm 11 is de-energized, with no buzzer alarm. When hydrogen peroxide refluxes, liquid level probe 1 cannot detect liquid and generates a feedback signal to liquid level relay 6. Liquid level relay 6 remains normally closed, and buzzer alarm 11 is energized, emitting a buzzer sound and accompanied by a flashing red light, thereby notifying staff of the abnormal hydrogen peroxide reflux. When the on-duty staff notice the buzzer sound and / or the flashing red light, they promptly go to the site and take standardized measures to minimize the impact of hydrogen peroxide reflux on product quality.

[0031] Example 2, a hydrogen peroxide backflow monitoring and alarm device for a filling machine, the structure of which is referenced Figure 1-3 shown.

[0032] Before designing and implementing the solution of Example 1, to address the issue of workers not easily noticing hydrogen peroxide not refluxing, a proposal was made to install a transparent observation tube 13 in the middle of the hydrogen peroxide reflux pipe 4. This solution would allow workers to observe the reflux situation within the hydrogen peroxide reflux pipe 4 and monitor the reflux status in real time. However, this approach required dedicated personnel to constantly monitor the reflux status of each production line, which was labor-intensive. Therefore, the solution of Example 1 was subsequently designed to save manpower.

[0033] This embodiment retains the design of the transparent observation tube 13 on the basis of the embodiment 1. After the buzzer alarm 11 sounds, the staff can go to the site and verify whether the hydrogen peroxide has no backflow by observing the transparent observation tube 13, and determine whether there is a fault in the embodiment 1 device that causes the false alarm, thereby facilitating maintenance of the embodiment 1 device.

[0034] Furthermore, the two ends of the transparent observation tube 13 are connected to the hydrogen peroxide return pipe 4 through pipe joints 14. This structure can also be used in Example 1, and the device can be quickly installed in the hydrogen peroxide return pipe 4 through the pipe joints 14.

[0035] Example 3, a hydrogen peroxide backflow monitoring and alarm device for a filling machine, the structure of which is referenced Figure 2-3 As shown in the figure, based on Example 2, a protective frame 15 is provided outside the transparent observation tube 13. This overcomes the problem of the glass transparent observation tube 13 being weak and preventing it from being accidentally touched and broken. Specifically, the protective frame 15 is constructed of two metal rings connected by a plurality of spaced metal protective rods.

[0036] Example 4, a hydrogen peroxide backflow monitoring and alarm device for a filling machine, the structure of which is referenced Figure 2 On the basis of Example 3, a filter 16 is provided on the hydrogen peroxide reflux pipe 4, and the filtering function of the existing filter 16 is utilized to increase the service life of the hydrogen peroxide reflux facility.

[0037] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
