Description

Technical Field

[0001] This utility model belongs to the field of sealed cleaning tanks, specifically a sealed cleaning tank for sealing the bipolar plate body of a fuel cell. Background Technology

[0002] The sealing material of the bipolar plate body of the fuel cell is used to prevent the loss of hydrogen, oxygen and moisture in the battery and ensure the efficient operation of the system. However, the sealing material is in close contact with the surface of the bipolar plate and is easily contaminated, which leads to a decrease in the sealing effect. Therefore, these sealing components need to be cleaned regularly using a cleaning tank.

[0003] When cleaning the sealing material of the fuel cell bipolar plate using a cleaning tank, the bipolar plate is first placed inside the cleaning tank. A pump then delivers cleaning water to a high-pressure flushing head, which sprays water onto the bipolar plate. This high-pressure water flow washes the sealing surface of the bipolar plate, removing loose contaminants. However, in actual use, the water flow washes the sealing surface of the bipolar plate, carrying away contaminants. This results in prolonged washing operations that waste a significant amount of water. Furthermore, high-pressure water washing alone is insufficient to remove firmly attached dirt, thus affecting the quality of the cleaning.

[0004] In summary, this utility model provides a sealing cleaning tank for sealing the bipolar plate body of a fuel cell, thereby solving the above-mentioned problems. Utility Model Content

[0021] Example 1

[0022] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a sealing cleaning tank for sealing the bipolar plate body of a fuel cell, including a cleaning unit 1. A liquid storage unit 2 is provided on the top of the cleaning unit 1. The liquid storage unit 2 includes a rinsing tank 21, and a filter screen 3 is movably connected to the inner cavity of the rinsing tank 21. The cleaning unit 1 includes a liquid storage tank 11, and a first motor 12 is provided at the bottom of the inner cavity of the liquid storage tank 11. The output shaft of the first motor 12 is driven to a stirring frame 13. A second motor 22 is provided above the rinsing tank 21, and the output shaft of the second motor 22 extends to the inner cavity of the rinsing tank 21 and is driven to a perforated cylinder 23. A transfer pump 24 is fixedly connected to one side of the liquid storage tank 11. One end of the transfer pump 24 is connected to the liquid storage tank 11, and the other end is connected to a transfer pipe 25. The other end of the transfer pipe 25 is connected to a ring pipe 26, and the bottom of the ring pipe 26 is connected to a high-pressure nozzle.

[0023] like Figure 1-4As shown, the bipolar plates can be placed through the perforated tube 23. Water and cleaning agents are stored inside the storage tank 11. The output shaft of the first motor 12 drives the stirring frame 13 to rotate, stirring the water and cleaning agents to ensure uniform mixing. The transfer pump 24 transports the mixture from the storage tank 11 to the inner cavity of the transfer pipe 25 and the ring pipe 26. The high-pressure nozzle at the bottom of the ring pipe 26 sprays the mixture onto the surface of the bipolar plates, thereby flushing away dirt from the sealing material on the surface of the bipolar plates. In addition, during the rinsing process, the cleaning agent dissolves stubborn dirt, and at the same time, the output shaft of the second motor 22 drives the orifice cylinder 23 to rotate, causing the orifice cylinder 23 to cause the internal bipolar plates to flip and change position, so that the bipolar plates are evenly rinsed, ensuring the quality of cleaning of the sealing material on the surface of the bipolar plates. After use, the water and cleaning agent will pass through the filter screen 3, which will filter and intercept impurities in the water and cleaning agent. The filtered water will be stored in the storage tank 11 for later reuse, effectively saving water resources.

[0024] Example 2

[0025] Reference Figure 1 , 2 4 and 5 represent the second embodiment of this utility model, which is based on the previous embodiment.

[0026] In this embodiment, fixing plates 221 are fixedly connected to both sides of the second motor 22, and the end of the fixing plate 221 away from the second motor 22 is fixedly connected to the ring pipe 26.

[0027] Electric push rods 261 are fixedly connected to both sides of the flushing tank 21. A connecting plate is fixedly connected to the output end of the electric push rod 261, and one side of the connecting plate is fixedly connected to the ring pipe 26.

[0028] Limiting grooves 211 are provided on both sides of the inner cavity of the rinsing tank 21. Limiting blocks 31 are fixedly connected to both sides of the surface of the filtrate screen 3. The limiting blocks 31 are located in the inner cavity of the limiting grooves 211 and are slidably connected to the inner cavity of the limiting grooves 211.

[0029] like Figure 1 , 2As shown in Figure 4, the output end of the electric push rod 261 drives the connecting plate to move upward, and the connecting plate drives the ring tube 26 to move upward. Since the ring tube 26 and the second motor 22 are fixed together by the fixing plate 221, the ring tube 26 can synchronously drive the second motor 22 to move upward, so that the second motor 22 drives the orifice tube 23 to gradually move upward away from the inner cavity of the rinsing tank 21, which is convenient for placing or removing the bipolar plate. And through the movement of the filter screen 3 in the inner cavity of the rinsing tank 21, after the orifice tube 23 is separated from the inner cavity of the rinsing tank 21, the filter screen 3 can be pulled, and the filter screen 3 drives the limiting block 31 to slide along the inner cavity of the limiting groove 211, which can limit the filter screen 3. At the same time, the filter screen 3 will gradually move upward away from the inside of the rinsing tank 21, which is convenient for cleaning the filter screen 3.

[0030] Example 3

[0031] Reference Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0032] In this embodiment, a protective cover 121 is fixedly connected to the bottom of the inner cavity of the liquid storage tank 11, and the first motor 12 is located in the inner cavity of the protective cover 121, and the bottom of the inner cavity of the protective cover 121 is fixedly connected.

[0033] A drain pipe 112 is connected to the lower end of one side of the liquid storage tank 11, and an inlet hopper 111 is connected to the upper end of one side of the liquid storage tank 11. A valve is provided on the surface of the drain pipe 112, and a round cover is provided on the top of the inlet hopper 111.

[0034] like Figure 3 As shown, the protective cover 121 can cover and protect the first motor 12, preventing the first motor 12 from being damaged by external water and cleaning agents. The cleaning agent and water can be transferred to the storage tank 11 for internal storage through the liquid inlet 111, and the water and cleaning agent used for a long time can be discharged through the drain pipe 112.

[0035] In use, the output end of the electric push rod 261 first drives the connecting plate to move upward, and the connecting plate drives the ring tube 26 to move upward. Since the ring tube 26 and the second motor 22 are fixed together by the fixing plate 221, the ring tube 26 can synchronously drive the second motor 22 to move upward, so that the second motor 22 drives the orifice tube 23 to gradually move upward away from the inner cavity of the flushing tank 21. Then, the bipolar plate is placed inside the orifice tube 23. Next, the electric push rod 261 drives the ring tube 26, the second motor 22 and the orifice tube 23 to move downward again, so that the orifice tube 23 re-enters the inner cavity of the flushing tank 21. Water and cleaning agent are transferred to the inner cavity of the storage tank 11 through the liquid inlet hopper 111 for storage. Then, the output shaft of the first motor 12 drives the stirring frame 13 to rotate, and the stirring frame 13 stirs the water and cleaning agent to make them mixed. The mixture is uniformly mixed. The pump 24 operates to transfer the mixture inside the storage tank 11 to the inner cavity of the transfer pipe 25 and the ring pipe 26. The high-pressure nozzle at the bottom of the ring pipe 26 sprays the mixture onto the surface of the bipolar plate, thereby flushing away the dirt on the sealing material of the bipolar plate surface. During the flushing process, the cleaning agent dissolves stubborn dirt. At the same time, the output shaft of the second motor 22 drives the orifice 23 to rotate, causing the orifice 23 to rotate and change the position of the internal bipolar plate, so that the bipolar plate is evenly flushed, ensuring the quality of cleaning of the sealing material on the surface of the bipolar plate. After use, the water and cleaning agent will pass through the filter screen 3, which will filter and intercept impurities in the water and cleaning agent. The filtered water will be stored back into the storage tank 11 for later use, effectively saving water resources.
