Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning equipment, and particularly relates to an efficient cleaning system for an airborne water boiler. Background Art

[0002] Fixed airborne water boilers are generally required to be equipped on civil aviation aircraft to supply hot water. However, after long-term use, a relatively thick scale of calcium and magnesium ion precipitation will adhere to the inner wall of the water boiler container, resulting in a reduction in the heating efficiency of the water boiler, a decrease in the container volume, and blockages and failures, affecting the use of the water boiler. To ensure the use of the water boiler and reduce the failure rate, it is often necessary to clean the scale.

[0003] Most of these types of water boilers are currently fully automatic or semi-automatic. Although they are convenient and fast to use, their structures are relatively complex, often difficult to disassemble, and very difficult to clean. At present, although the failure repair rate is significantly reduced after cleaning, there are still some deficiencies. The main problem is that civil aviation maintenance personnel use manual disassembly and cleaning methods for fixed airborne water boilers. The disassembly difficulty is large, the required working hours are long, and there may still be some dirt adhering to each pipeline after cleaning, which has a greater impact on water quality; moreover, manual cleaning is time-consuming and laborious, with low work efficiency and great inconvenience.

[0004] Therefore, we propose an efficient cleaning system for an airborne water boiler to solve the above technical problems. Summary of the Invention

Detailed implementation mode

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0037] Embodiment:

[0038] Refer to Figure 1 , this embodiment provides an efficient cleaning system for an airborne water boiler, including:

[0039] Medicine washing device, including a liquid medicine tank 1 and a medicine supply pipe 2. A liquid adding pipe 3 is connected to the liquid medicine tank 1. The medicine supply pipe 2 is connected to the liquid medicine tank 1, and a metering chemical pump 4 is provided on the medicine supply pipe 2;

[0040] Cleaning device, including a cleaning pipe 5, a cleaning check valve 6 and a clean water pH sensor 7. The cleaning pipe 5 is connected to a water source, and both the cleaning check valve 6 and the clean water pH sensor 7 are arranged on the cleaning pipe 5;

[0041] Four cleaning stations 8 for installing a water boiler. The water inlet and outlet of the water boiler are respectively connected to a liquid inlet pipeline 9 and a liquid outlet pipeline 10. A three-way pipeline switching valve I 11 is connected to the liquid inlet pipeline 9. The medicine supply pipe 2 and the cleaning pipe 5 are both connected to the three-way pipeline switching valve I 11. A cleaning station pH sensor 12 is provided on the liquid outlet pipeline 10;

[0042] Control system, including a PLC controller, the metering chemical pump 4, the clean water pH sensor 7, the three-way pipeline switching valve 11 and the cleaning station pH sensor 12 are all electrically connected to the PLC controller, and the PLC controller is also connected with a display screen for displaying measurement data.

[0043] Specifically, without disassembling the water boiler, this system can clean four water boilers at one time. Refer to Figure 2 and Figure 3 . During the cleaning process, pickling and descaling work and water washing work are carried out successively to achieve a comprehensive cleaning of the inner tank, pipeline and valve of the water boiler, etc., and reduce the failure rate. The PLC controller is used to realize the automatic control of the cleaning process, and the pH values before and after cleaning are compared. When the value of the cleaning station pH sensor 12 is greater than or equal to the value of the clean water pH sensor 7, the power is cut off, and it is considered that the inside of the water boiler reaches the drinking standard at this time. Compared with the manual disassembly and assembly cleaning method, it takes 3 hours to clean one machine manually, while this system only takes half an hour to clean, effectively reducing the work intensity, improving the cleaning efficiency and cleaning effect, and being convenient to use.

[0044] In a specific embodiment:

[0045] The liquid outlet pipeline 10 includes a collector 1001, a three-way pipeline switching valve 1002, a waste liquid discharge pipeline 1003 and a liquid medicine recovery pipeline 1004. The collector 1001 is located below the water outlet of the water boiler. The collector 1001, the waste liquid discharge pipeline 1003 and the liquid medicine recovery pipeline 1004 are all communicated with the three-way pipeline switching valve 1002. The cleaning station pH sensor 12 is connected to the waste liquid discharge pipeline 1003. The liquid medicine recovery pipeline 1004 is communicated with the liquid medicine tank 1. A primary filter 13 is provided on the medicine supply pipe 2. The three-way pipeline switching valve 1002 is electrically connected to the PLC controller. Specifically, by switching the three-way pipeline switching valve 1002, the discharge of the cleaning waste liquid of the water boiler can be controlled. By discharging the pickling liquid medicine into the liquid medicine recovery pipeline 1004, it is recycled into the liquid medicine tank 1, and the impurities in the pickling liquid medicine are filtered by the primary filter 13 on the medicine supply pipe 2, realizing the recycling of the pickling liquid medicine, reducing the cleaning cost, reducing the waste liquid discharge, reducing the pollution, and being environmentally friendly.

[0046] In a further embodiment:

[0047] Refer to Figure 2, a liquid medicine tank heater 14 is provided inside the liquid medicine tank 1, and a liquid medicine tank temperature sensor 15 is provided on the liquid medicine tank 1. Both the liquid medicine tank heater 14 and the liquid medicine tank temperature sensor 15 are electrically connected to the PLC controller. Specifically, through the liquid medicine tank heater 14 and the liquid medicine tank temperature sensor 15, the temperature of the pickling liquid medicine can be controlled. Under normal circumstances, the pickling liquid medicine used is food cleaning oxalic acid. When cleaning the water boiler, by setting the heating temperature of the pickling liquid medicine to 40 °C, the pickled liquid medicine after heating can quickly dissolve scale, reduce the cleaning time, and facilitate use.

[0048] Refer to Figure 3 , a liquid medicine tank water adding pipe 16 is connected to the cleaning pipe 5. A liquid medicine tank water adding valve 17 is provided on the liquid medicine tank water adding pipe 16. The liquid adding pipe 3 is located below the liquid medicine tank water adding valve 17. The liquid medicine tank 1 is connected to a liquid medicine tank sewage discharge pipe 18, and a liquid medicine tank sewage discharge valve 19 is provided on the liquid medicine tank sewage discharge pipe 18. Specifically, through the liquid adding pipe 3, pickling liquid medicine and water can be added into the liquid medicine tank 1, so as to supplement and dilute the pickling liquid medicine. At the same time, the liquid medicine that has been circulated in the liquid medicine tank 1 for multiple times is regularly discharged through the liquid medicine tank sewage discharge valve 19, and water is continuously introduced into the liquid adding pipe 3 to wash the inside of the liquid medicine tank 1, which is beneficial for use.

[0049] Refer to Figure 2 , a liquid medicine tank liquid level sensor 20 and a liquid medicine tank PH value sensor 21 are provided on the liquid medicine tank 1. Both the liquid medicine tank liquid level sensor 20 and the liquid medicine tank PH value sensor 21 are electrically connected to the PLC controller. Specifically, the liquid level height inside the liquid medicine tank 1 and the PH value of the liquid medicine are judged through the liquid medicine tank liquid level sensor 20 and the liquid medicine tank PH value sensor 21. Under normal circumstances, when the PH value of the liquid medicine exceeds 4, the cleaning effect of the water boiler will become worse, and it is necessary to supplement and adjust the PH value of the liquid medicine in the liquid medicine tank 1 to ensure the cleaning effect of the water boiler.

[0050] In a specific embodiment:

[0051] Refer to Figure 1 and Figure 4 , the high-efficiency cleaning system of the airborne water boiler further includes a testing system. The testing system includes a testing station 22 and a testing water pipe. The testing station 22 is used to test the water boiler after cleaning. Both ends of the testing water pipe are respectively connected to the cleaning pipe 5 and the water inlet of the water boiler. A constant temperature component for maintaining the water temperature is provided on the testing water pipe, and the constant temperature component is electrically connected to the PLC controller.

[0052] In a further embodiment:

[0053] Refer to Figure 4, the test water pipe includes a test water inlet pipe 23 and a test water outlet pipe 24. One end of the test water inlet pipe 23 is connected to the cleaning pipe 5, and the other end is connected to the constant temperature assembly. One end of the test water outlet pipe 24 is connected to the constant temperature assembly, and the other end is connected to the water inlet of the water boiler.

[0054] Refer to Figure 4 , the constant temperature assembly includes a clean water tank 25, a constant temperature machine 26, a circulation inlet pipe 27, a circulation outlet pipe 28, and a constant temperature machine circulation valve 29. Both the test water inlet pipe 23 and the test water outlet pipe 24 are connected to the clean water tank 25. The constant temperature machine 26 and the clean water tank 25 are connected through the circulation inlet pipe 27 and the circulation outlet pipe 28. The constant temperature machine circulation valve 29 is arranged on the circulation inlet pipe 27. Both the constant temperature machine 26 and the constant temperature machine circulation valve 29 are electrically connected to the PLC controller.

[0055] Refer to Figure 1 , a three-way pipeline switching valve three 30 is arranged on the test water outlet pipe 24. The remaining two ends of the three-way pipeline switching valve three 30 are respectively connected to the cleaning pipe 5 and the water inlet of the water boiler. The three-way pipeline switching valve three 30 is electrically connected to the PLC controller.

[0056] Refer to Figure 4 , a direct drinking filter 31 is arranged on the test water inlet pipe 23. A frequency conversion water pump 32, a pressure sensor 33, and a flow sensor 34 are sequentially arranged on the test water outlet pipe 24. The frequency conversion water pump 32, the pressure sensor 33, and the flow sensor 34 are all electrically connected to the PLC controller.

[0057] Specifically, under normal circumstances, the system water source temperature is set. When the temperature does not meet the range of 17 - 22 °C, the test bench will start the constant temperature machine 26 to adjust the water temperature in the test water tank to the system required temperature. If the temperature exceeds the range, the test system cannot work. Using the water in this temperature range to conduct a pressure test on the water boiler after cleaning can reduce errors. When testing, the water source pressure is set to 0 - 145 Psi. After the frequency conversion water pump 32 and the pressure sensor 33 are powered on, they start to work in coordination. Before the pressure reaches the set value of 80 Psi of the water boiler safety valve, it is ensured that no water flows out. After exceeding 80 Psi, water can flow out, so as to ensure that the water boiler can be sealed when the pressure is lower than the opening pressure value and can supply water when the pressure is higher than the opening pressure value, in order to test the use effect of the water boiler and facilitate confirming whether maintenance is required.

[0058] In a specific embodiment:

[0059] Refer to Figure 1 , the high-efficiency cleaning system of the airborne water boiler further includes an air compressor air drying system. The air compressor air drying system includes an air compressor 35 and an air gun 36, which are used to blow dry the inner tank body, pipelines, valves, etc. of the water boiler, so as to ensure that clean and hygienic drinking water is provided for passengers.

[0060] Refer to Figure 5 , this embodiment also provides an efficient cleaning device for an airborne water boiler, including an efficient cleaning system for an airborne water boiler as described above. It is a special device manufactured by Chengdu Dongkexin Aviation Automatic Control Equipment Co., Ltd. for its self-developed 4510 series water boilers. This device is controlled automatically and is equipped with sound and light prompts. It can complete the full-path cleaning of the water boiler and the water boiler, can clean four 4510 series water boilers at a time, and can also be tested separately after cleaning, reducing the work intensity, improving the work efficiency, and under the same scaling conditions, shortening the cleaning time by 30% compared with the current situation. In addition, by recycling the pickling solution, it can reduce the cleaning cost, reduce the waste liquid discharge, and is beneficial to use.
