Description

Technical Field

[0001] This application relates to the field of equipment technology for producing green hydrogen through water electrolysis, and in particular to a cleaning device. Background Technology

[0002] In the process of hydrogen production by water electrolysis, the core component of the electrolysis unit, the electrolytic cell, contains a porous current collector. Oxidation of the current collector will reduce the chemical performance of the electrolytic cell and shorten its service life. To prevent oxidation of the porous material current collector, the porous material needs to be cleaned during the protective treatment process to ensure a tight bond between the protective layer and the porous material.

[0003] Porous materials have a wide variety of pore sizes and diverse pore structures, making it difficult to thoroughly clean contaminants deep within the pores. Current methods fall into two categories: immersing the porous material in pure water in a container and repeatedly changing the water for rinsing; and immersing the porous material in pure water in an ultrasonic container and repeatedly changing the water for ultrasonic treatment. However, these existing technologies require large amounts of pure water and are time-consuming, while also resulting in low cleaning quality and wastewater pollution, which is detrimental to environmental protection and resource conservation.

[0004] There are currently no effective solutions to the technical problems of high water consumption, wastewater pollution, low cleaning efficiency, and difficulty in ensuring cleaning quality in the existing technologies. Utility Model Content

[0005] This invention provides a cleaning device that at least solves the technical problems of high water consumption, wastewater pollution, low cleaning efficiency, and difficulty in ensuring cleaning quality in the existing technology.

[0006] According to an embodiment of this application, a cleaning device is provided, including a water supply device and a cleaning device, wherein the water supply device and the water inlet of the cleaning device are connected by a pipeline. The cleaning device also includes a collection device, which is connected to the outlet of the cleaning device by a pipeline. The collection device includes multiple separation tanks, each of which is connected to the cleaning device by a pipeline for collecting different discharges from the cleaning device during the cleaning process.

[0007] Therefore, the cleaning apparatus provided according to the embodiments of this application includes multiple separation tanks connected to the cleaning equipment via pipelines in the collection device connected to the discharge port of the cleaning equipment. Each separation tank corresponds to different effluents after multiple cleaning processes, thus enabling graded collection of effluents and providing a basis for subsequent separate recycling of effluents, thereby reducing the generation of pollutants after the cleaning process. Simultaneously, during the cleaning process, multiple cleaning cycles allow for control of the water supply to each cleaning stage, thereby reducing the overall water consumption of the cleaning process. This solves the technical problems of high water consumption, wastewater pollution, low cleaning efficiency, and difficulty in ensuring cleaning quality in the prior art.

[0014] Figure 1 A schematic diagram of the cleaning apparatus 10 according to this embodiment is shown. Specifically, refer to... Figure 1 As shown, the cleaning device 10 includes a water supply device 400 and a cleaning device 300, wherein the inlets of the water supply device 400 and the cleaning device 300 are connected by pipelines. The cleaning device 10 also includes a collection device 200, which is connected to the outlet of the cleaning device 300 by pipelines. The collection device 200 includes multiple separation tanks, each of which is connected to the cleaning device 300 by a pipeline for collecting different discharges from the cleaning device 300 during the cleaning process.

[0015] Specifically, during the cleaning process, the water supply device 400 is connected to the inlet of the cleaning device 300 via a pipeline to provide pure water to the cleaning device 300. The cleaning device 300 uses pure water to clean the object 310. The effluent generated after cleaning is transported to the collection device 200 through the outlet of the cleaning device 300. Multiple separation tanks in the collection device can achieve graded collection of different effluents for subsequent recycling. Therefore, compared with the problem of wastewater pollution after cleaning in the prior art, the present application uses multiple separation tanks to grade and collect different effluents, which can achieve the technical effect of reducing wastewater pollution after cleaning.

[0016] As described in the background section, in the process of hydrogen production by water electrolysis, the core component of the electrolysis unit, the electrolytic cell, contains a porous current collector. Oxidation of the current collector will reduce the chemical performance of the electrolytic cell and shorten its service life. To prevent oxidation of the porous material current collector during the protective treatment process, the porous material needs to be cleaned to ensure a tight bond between the protective layer and the porous material. Porous materials have diverse pore sizes and channel structures, making it difficult to thoroughly clean contaminants deep within the pores. Current methods fall into two categories: immersing the porous material in pure water in a container and repeatedly changing the water for soaking and rinsing; and immersing the porous material in pure water in an ultrasonic container and repeatedly changing the water for ultrasonic treatment. However, the existing technologies require a large amount of pure water and are time-consuming, resulting in low cleaning quality and wastewater pollution, which is detrimental to environmental protection and resource conservation.

[0017] In view of this, the cleaning equipment provided in this embodiment includes a collection device connected to the outlet of the cleaning equipment, which is equipped with multiple separation tanks, each connected to the cleaning equipment via pipelines. Each separation tank corresponds to different effluents after multiple cleaning processes, thus enabling graded collection of effluents and providing a basis for subsequent separate recycling, thereby reducing the generation of pollutants after the cleaning process. Simultaneously, during the cleaning process, multiple cleaning cycles allow for control of the water supply to each cleaning stage, thereby reducing the overall water consumption of the cleaning process. This solves the technical problems of high water consumption, wastewater pollution, low cleaning efficiency, and difficulty in ensuring cleaning quality in the prior art.

[0018] Optionally, the collection device 200 also includes a vacuum suction device 280, wherein each separation tank is connected to the vacuum suction device 280 via a pipeline.

[0019] Specifically, the vacuum suction device 280 is connected to each of the separation tanks in the collection device 200 via pipelines. Therefore, the suction force generated by the vacuum suction device 280 can draw the discharge generated by the cleaning device 200 into each separation tank. This achieves the collection of the discharge generated by the cleaning device 200.

[0020] Optionally, the collection device 200 further includes a first valve group 240, wherein the first valve group 240 includes multiple valves respectively disposed in the pipeline between each separation tank and the cleaning device 300, for controlling the connection between the cleaning device 300 and each separation tank; and a second valve group 260, wherein the second valve group 260 includes multiple valves respectively disposed between each separation tank and the vacuum suction device 280, for controlling the connection between the vacuum suction device 280 and each separation tank.

[0021] Specifically, a first valve group 240 and a second valve group 260, comprising multiple valves, are installed on the connecting pipeline of the collection device 200. The first valve group 240 is installed on the pipeline between each separation tank and the cleaning device 300, and the second valve group 260 is installed on the pipeline between each separation tank and the vacuum suction device 280. Each valve in the valve group can control the opening and closing of the connecting pipeline to which it is placed.

[0022] This enables control over the connecting pipelines between each separation tank, the cleaning equipment 300, and the vacuum suction equipment 280, thereby achieving the technical effect of controlling the separate discharge of the effluent from the connecting pipelines.

[0023] Optionally, the plurality of separation tanks include: a first separation tank 210 for separating pollutants and gases; a second separation tank 220 for separating wastewater and gases; and a third separation tank 230 for separating cleaning water and gases.

[0024] Specifically, the collection device 200 includes multiple separation tanks connected to the cleaning device 300, namely a first separation tank 210, a second separation tank 220, and a third separation tank 230. Among them, the first separation tank 210 is used to separate the first-stage effluent (i.e., high-concentration pollutants) generated after cleaning, the second separation tank 220 is used to separate the second-stage effluent (i.e., wastewater) generated after cleaning, and the third separation tank 230 is used to separate the third-stage effluent (i.e., cleaning water) generated after cleaning.

[0025] Therefore, different discharges can be drawn into different separation tanks, thereby achieving graded collection of different discharges generated after cleaning the object 310.

[0026] Optionally, the first valve group 240 includes a first valve 241, a second valve 242, and a third valve 243, wherein the first valve 241 is disposed in the pipeline between the cleaning equipment 300 and the first separation tank 210; the second valve 242 is disposed in the pipeline between the cleaning equipment 300 and the second separation tank 220; and the third valve 243 is disposed in the pipeline between the cleaning equipment 300 and the third separation tank 230.

[0027] Specifically, a first valve group 240, comprising multiple valves, is installed on the pipeline connecting the collection device 200 and the cleaning device 300. The first valve 241 controls the opening and closing of the connecting pipeline between the first separation tank 210 and the cleaning device 300, the second valve 242 controls the opening and closing of the connecting pipeline between the second separation tank 220 and the cleaning device 300, and the third valve 243 controls the opening and closing of the connecting pipeline between the third separation tank 230 and the cleaning device 300.

[0028] When one of the valves in the first valve group 240 is opened, the discharge generated by the cleaning equipment 300 can be drawn into the corresponding separation tank.

[0029] For example, when the first valve 241 is opened, the contaminants generated by the cleaning equipment 300 can be drawn into the first separation tank 210. Similarly, when the second valve 242 is opened, the wastewater is drawn into the second separation tank 220, and when the third valve 243 is opened, the cleaning water is drawn into the third separation tank 230.

[0030] Therefore, the on / off state of the pipelines between each separation tank and the cleaning equipment 300 can be controlled separately, and each separation tank can separately absorb its corresponding discharge. This achieves the control of the connecting pipelines between each separation tank and the cleaning equipment 300, thereby achieving the technical effect of controlling the separate discharge of discharges in the connecting pipelines.

[0031] Optionally, the second valve group 260 includes a fourth valve 261, a fifth valve 262, and a sixth valve 263, wherein the fourth valve 261 is disposed in the pipeline between the vacuum suction device 280 and the first separation tank 210; the fifth valve 262 is disposed in the pipeline between the vacuum suction device 280 and the second separation tank 220; and the sixth valve 263 is disposed in the pipeline between the vacuum suction device 280 and the third separation tank 230.

[0032] Specifically, in the collection device 200, each separation tank is connected to the vacuum suction device 280 by a second valve group 260, which includes multiple valves. The fourth valve 261 controls the opening and closing of the connection pipeline between the first separation tank 210 and the vacuum suction device 280, the fifth valve 262 controls the opening and closing of the connection pipeline between the second separation tank 220 and the vacuum suction device 280, and the sixth valve 263 controls the opening and closing of the connection pipeline between the third separation tank 230 and the vacuum suction device 280.

[0033] When one valve in the first valve group 240 is opened, the valve in the second valve group 260 connected to the corresponding separation tank is opened simultaneously, the vacuum suction device 280 provides suction, and the discharge generated by the cleaning device 300 can be sucked into the corresponding separation tank.

[0034] For example, when the first valve 241 is opened, the fourth valve 261 in the second valve group 260 connected to the first separation tank 210 opens simultaneously, and the vacuum suction device 280 provides suction, allowing contaminants generated by the cleaning device 300 to be drawn into the first separation tank 210. Similarly, the fifth valve 262 can open simultaneously with the second valve 242, and the sixth valve 263 can open simultaneously with the third valve 243.

[0035] Therefore, the on / off state of the pipelines between each separation tank and the vacuum suction device 280 can be controlled separately, and each separation tank can extract its corresponding discharge. This achieves control over the connecting pipelines between each separation tank and the vacuum suction device 280, thereby achieving the technical effect of controlling the separate discharge of discharge in the connecting pipelines.

[0036] Optionally, the collection device 200 also includes a conductivity sensor 250, wherein the conductivity sensor 250 is disposed in the pipeline between the cleaning device 300 and the third separation tank 230, for measuring the conductivity of the cleaning water flowing from the cleaning device 300 to the third separation tank 230.

[0037] Specifically, a conductivity sensor 250 is installed on the pipeline between the cleaning equipment 300 and the third separation tank 230. When the third-stage discharge (i.e., cleaning water) generated by the cleaning equipment 300 is transported to the third separation tank 230 through the pipeline, the conductivity sensor 250 can measure the conductivity of the cleaning water in the connecting pipeline, convert it into an electrical signal to realize data output, and provide real-time monitoring for the control system or operator.

[0038] Therefore, when the conductivity sensor 250 measures that the conductivity of the cleaning water meets the preset requirements, the cleaning of the object 310 will end, and the cleaning process will begin for the next object 310. This avoids the problem of high water consumption caused by repeatedly rinsing the same object 310.

[0039] Optionally, the collection device 200 also includes a first discharge valve 271 connected to the first separation tank 210, a second discharge valve 272 connected to the second separation tank 220, and a third discharge valve 273 connected to the third separation tank 230.

[0040] Specifically, in the collection device 200, the first discharge valve 271 is connected to the first separation tank 210, the second discharge valve 272 is connected to the second separation tank 220, and the third discharge valve 273 is connected to the third separation tank 230. Opening the discharge valves can discharge the effluent collected in each of the connected separation tanks.

[0041] Therefore, after the effluent generated by the cleaning equipment 300 is transported to each separation tank, the pollutants collected in the first separation tank 210 can be discharged by opening the first discharge valve 271, the wastewater collected in the second separation tank 220 can be discharged by opening the second discharge valve 272, and the cleaning water collected in the third separation tank 230 can be discharged by opening the third discharge valve 273. This achieves the graded discharge of the effluent collected in each separation tank for subsequent graded recycling and treatment operations.

[0042] Optionally, the vacuum suction device 280 includes a vacuum pump 281 and a vacuum pressure buffer tank 282, wherein the vacuum pump 281 and the vacuum pressure buffer tank 282 are connected by pipelines; and the vacuum pressure buffer tank 282 is connected to multiple separation tanks by pipelines.

[0043] Specifically, vacuum pump 281 is connected to each separation tank via vacuum pressure buffer tank 282. Vacuum pump 281 is used to remove gas from vacuum pressure buffer tank 282 to reduce the internal pressure of the container and maintain the internal pressure of the container at a preset target vacuum level. Vacuum pressure buffer tank 282 is used to stabilize the vacuum level of collection device 200. Thus, vacuum suction device 280 can generate suction, achieving the technical effect that each separation tank connected to vacuum suction device 280 can suck up the discharged material from cleaning device 300.

[0044] Optionally, the vacuum suction device 280 also includes a vacuum sensor 283 disposed in the vacuum pressure buffer tank 282.

[0045] Specifically, in the vacuum suction device 280, the vacuum sensor 283 is connected to the vacuum pressure buffer tank 282 to measure the vacuum level inside the vacuum pressure buffer tank 282, and converts the change in vacuum pressure into an electrical signal to output data for real-time monitoring by the control system or operator.

[0046] Therefore, when the vacuum sensor 283 measures that the vacuum level inside the vacuum pressure buffer tank 282 meets the preset requirements, the first valve group 240 and the second valve group 260 will be opened, allowing flow in the pipelines between the cleaning equipment 300 and each separation tank, as well as between the vacuum suction equipment 280 and each separation tank. Thus, under the suction force of the vacuum suction equipment 280, the discharge from the cleaning equipment 300 can be collected by each separation tank through the pipelines.

[0047] Optionally, the cleaning device 300 includes a platform 320, a spray chamber 330, a sealing ring gasket 340, and a movable spray head 350. The platform 320 is used to place the object to be cleaned 310, and the outlet of the platform 320 is connected to the collection device 200. The spray chamber 330 and the platform 320 are sealed together by the sealing ring gasket 340, thereby forming a closed space for cleaning the object to be cleaned 310. The movable spray head 350 is connected to the water supply device 400 and is disposed in the spray chamber 330 for atomizing the pure water provided by the water supply device 400.

[0048] Specifically, the object to be cleaned 310 is placed on the platform 320, and the spray chamber 330 and the platform 320 are sealed together by a sealing ring gasket 340 to achieve a full-enclosed coverage of the object to be cleaned 310. The movable spray head 350 set in the spray chamber 330 converts the pure water provided by the water supply equipment 400 into water mist and sprays the water mist onto the object to be cleaned 310.

[0049] Therefore, the movable spray head 350, due to its movable nature, can evenly spray water mist onto the object being cleaned 310. Furthermore, the enclosed space between the spray chamber 330 and the platform 320 prevents water mist leakage and subsequent water waste. This enables efficient and high-quality cleaning of the object being cleaned 310.

[0050] Optionally, the water supply equipment 400 includes a pure water tank 410 and a pure water pump 420, wherein the outlet of the pure water tank 410 is connected to the pure water pump 420 through a pipeline, and the pure water pump 420 is connected to the cleaning equipment 300 through a pipeline for supplying pure water to the cleaning equipment 300.

[0051] Specifically, the pure water pump 420 draws pure water from the pure water tank 410 and delivers it to the cleaning equipment 300, thereby providing pure water for the cleaning of the object 310.

[0052] Optionally, a seventh valve 431 is provided in the pipeline between the pure water pump 420 and the cleaning equipment 300, and the water supply equipment 400 is also provided with a circulation pipeline 433, wherein one end of the circulation pipeline 433 is provided in the pipeline between the pure water pump 420 and the seventh valve 431, the other end of the circulation pipeline 433 is connected to the inlet of the pure water tank 410, and the circulation pipeline 433 is provided with an eighth valve 432.

[0053] Specifically, in actual operation, the pure water pump 420 operates continuously. After the object to be cleaned 310 is placed on the platform 320, the seventh valve 431 is opened, connecting the pipeline between the pure water pump 420 and the cleaning equipment 300. This allows pure water from the pure water tank 410 to be delivered to the cleaning equipment 300 for cleaning. When the cleaning is complete and the object to be cleaned needs to be changed, the seventh valve 431 can be closed and the eighth valve 432 opened. This connects the circulation pipeline 433 between the inlet of the pure water tank 410 and the pure water pump 420, allowing the pure water in the tank 410 to circulate even when the cleaning equipment 300 does not require water supply, while simultaneously allowing for the replacement of the object to be cleaned.

[0054] In this way, the flow of pure water pump 420 between the pure water pump 420 and the cleaning equipment 300 can be controlled without shutting down the pure water pump 420. This is beneficial for the maintenance of the pure water pump 420 and can avoid the waste of water resources caused by unnecessary cleaning work.

[0055] Optionally, the water supply equipment 400 also includes a water pressure sensor 440, wherein the water pressure sensor 440 is disposed in the pipeline between the pure water pump 420 and the seventh valve 431.

[0056] Specifically, the water pressure sensor 440 measures the water pressure in the pipeline between the pure water pump 420 and the seventh valve 431, converting changes in water pressure into electrical signals for data output, which is then monitored in real time by the control system or operators. This prevents excessive water pressure from damaging the water supply equipment 400 and the cleaning equipment 300. Optionally, the cleaning device 10 further includes a PLC control console 100, which is communicatively connected to the collection device 200 and the water supply device 400, and is used to control the on / off and switching of the pipelines of the collection device 200 and the water supply device 400.

[0057] Specifically, the PLC control console 100 is equipped with multiple buttons, which correspond to the vacuum pump 281, the pure water pump 420, and multiple valves, respectively.

[0058] First, the object to be cleaned 310 is placed in the sealed space between the spray chamber 330 and the platform 320, and the PLC control console 100 starts the vacuum pump 281. When the vacuum sensor 283 measures that the vacuum level inside the vacuum pressure buffer tank 282 meets the preset requirements, the PLC control console 100 opens the first valve 241 and the fourth valve 261, and the contaminants are collected into the first separation tank 210. After collection is completed, the PLC control console 100 closes the first valve 241 and the fourth valve 261.

[0059] Furthermore, after pollutant collection is completed, the eighth valve 432 is open. The PLC control panel 100 starts the pure water pump 420, which closes the eighth valve 432. The ninth valve 370 on the air inlet pipe 360 ​​opens first, followed by the seventh valve 431 on the pipe between the pure water pump 420 and the cleaning equipment 300. The pure water is atomized and sprayed onto the cleaning object 310 by the movable spray head 350 for cleaning. After cleaning, the PLC control panel 100 opens the eighth valve 432 and closes the ninth valve 370 and the seventh valve 431. During the collection process, the PLC control panel 100 opens the second valve 242 and the fifth valve 262, and the wastewater is collected into the second separation tank 220. After collection, the PLC control panel 100 closes the second valve 242 and the fifth valve 262.

[0060] Finally, after the wastewater collection is completed, the cleaning steps for the cleaning object 310 are the same as above. During the collection process, the PLC control panel 100 opens the third valve 243 and the sixth valve 263, and the wastewater is collected into the third separation tank 230. After the collection is completed, the PLC control panel 100 closes the third valve 243 and the sixth valve 263.

[0061] The above describes a cleaning and collection process based on each step being repeated once. During operation, operators can set parameters on the PLC control panel 100 according to production requirements, such as vacuum level, suction time, spray time, and number of rinsing cycles. The cleaning device 10 will then operate automatically according to the set program.

[0062] This eliminates the need for operators to manually close each valve, avoiding the low cleaning efficiency caused by manual operation. Consequently, the cleaning device 10 achieves the technical effect of automatically operating according to a set program, thus improving cleaning efficiency.

[0063] Optionally, the cleaning device 300 also includes an air inlet pipe 360 ​​connected to the spray chamber 330, and the air inlet pipe 360 ​​is provided with a ninth valve 370.

[0064] Specifically, during the process of collecting discharge in the second separator 220 and the third separator 230, the eighth valve 432 is initially open. However, when the pure water pump 420 starts, the eighth valve 432 will close, the ninth valve 370 on the air inlet pipe 360 ​​will open first, and the seventh valve 431 on the pipe between the pure water pump 420 and the cleaning equipment 300 will open later.

[0065] Thus, the high-speed airflow enters the intake pipe 360 ​​through the ninth valve 370, forming a low-pressure zone in the spray chamber 330. The movable spray head 350 can atomize pure water and then spray the water mist onto the object to be cleaned 310 for cleaning.
