Description

Technical Field

[0001] This invention relates to the field of anti-scaling testing technology, specifically to an anti-scaling testing device and method for enamel steel plates. Background Technology

[0002] To prevent safety hazards, functional failures, and economic losses caused by coating peeling off enamel-lined steel plates during use, it is necessary to test the anti-scaling performance of the enamel-lined steel plates before use. For example, patent application number CN202010483243.0 provides a dual-electrolysis test device and method for enamel-lined steel plate anti-scaling performance. This device clamps the enamel-lined steel plate between a cathode electrolytic cell and an anodic electrolytic cell. In this case, the cathode electrolytic cell is a hydrogen-filled area, and cathode polarization is applied by a galvanometer to generate hydrogen atoms that penetrate into the steel plate. The right electrolytic cell is the test area, and an anodic potential is applied by a potentiostat to detect the hydrogen atoms that have diffused to the right side. The hydrogen ions are oxidized to hydrogen ions, generating a detectable anodic current. The diffusion rate of hydrogen ions on the steel plate is then calculated, and the anti-scaling performance of the enamel steel plate is further calculated. This method is simple and accurate. In this experiment, the conventional clamping method is to tighten the clamps evenly with bolts, and the sealing ring on the clamp contacts the steel plate to achieve a seal. However, there may be problems such as incorrect clamping method or aging of the sealing ring, which may lead to leakage on both sides of the steel plate and affect the accuracy of the test results. Therefore, the sealing performance between the enamel steel plate and the cathode electrolytic cell and the anodic electrolytic cell must be checked before the test.

[0003] The conventional testing procedure is to first fill the left tank with clean water without electrolyte until the level reaches the standard test height, let it stand for 30 minutes, drain the water from the left tank, fill the right tank with clean water, and let it stand for another 30 minutes. At this time, observe the outside of the tank for any water droplets seeping out, wipe the edges of the steel plate and the bottom of the fixture with a dry towel to check for dampness, and use a measuring cup to check the amount of water added and the amount of water remaining after 30 minutes. If there is no significant decrease, it can be determined whether there is a leak. However, since water seepage occurs slowly between the sealing ring and the steel plate, it is necessary to observe whether there is water leakage at the seal after a period of time in order to determine the sealing effect. This method is time-consuming and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for testing the anti-scaling properties of enamel-lined steel plates, so as to solve the problems of long time and low efficiency in conventional methods for testing the sealing performance of anti-scaling properties of enamel-lined steel plates.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A device for detecting anti-scaling properties of enamel-coated steel plates includes a hydrogen permeation cell comprising a left electrolytic cell and a right electrolytic cell. Both the left and right electrolytic cells have permeation ports. Clamps are fixedly connected to both the left and right electrolytic cells, and each clamp is equipped with a sealing ring. The two clamps are used to hold the steel plate. A detection assembly is provided on the hydrogen permeation cell device. The detection assembly includes a detection cell that encloses both clamps. Sliding grooves are provided on both the left and right electrolytic cells, and pistons are slidably connected within these sliding grooves.

[0006] The conventional method, which involves adding water to both the left and right electrolytic cells, is prone to leakage. Since water seepage occurs slowly between the sealing ring and the steel plate, it requires a period of time to observe for leaks and determine the sealing effectiveness. This process is time-consuming and inefficient. This new design incorporates a detection component on the hydrogen permeation tank. This component includes a detection tank that encloses two clamps. When the clamps tighten on the steel plate, the detection tank covers the contact surfaces between the steel plate and the sealing ring. At this point, the detection tank is filled with water, submerging the steel plate. Pressure is then applied to both pistons, increasing the gas pressure inside the left and right electrolytic cells. When the seal ring is not properly sealed to the steel plate, air bubbles will form at the seal. By observing whether air bubbles are formed, the operator can determine the sealing effect between the steel plate and the seal ring, reducing testing time. Furthermore, it eliminates the need to add other solutions to the left and right electrolytic cells, thus avoiding the cleaning steps required before subsequent testing and simplifying the operation. Therefore, this design improves the testing rate of sealing performance, simplifies the testing process, and enhances the accuracy of the test through air pressure testing.

[0007] Preferably, the detection pool is provided with an observer, which is made of transparent material and has a rectangular groove inside. The observer's opening faces downward and is located directly above the two clamps.

[0008] It's easy to understand that because the contact area between the steel plate and the sealing ring is relatively large, when using the detection assembly to observe bubble formation during seal testing, one person cannot simultaneously observe both sides of the contact area. Therefore, two people are needed to observe from both sides of the equipment. Furthermore, when the leak point is small, the generated bubbles are also small, making them difficult to observe. This design addresses this by installing an observer inside the detection tank. The observer is made of transparent material and is placed upside down directly above the two clamps, ensuring it is filled with water. When bubbles are generated, they rise and enter the observer, settling at the bottom of the rectangular groove. This design can collect bubbles generated at any leak point between the steel plate and the sealing ring, allowing personnel to determine the sealing effect simply by observing the presence of bubbles inside the observer. Moreover, when the leak point is small and the generated bubbles are small, the observer can continuously collect bubbles, causing them to accumulate at the bottom of the rectangular groove and generate larger bubbles, thus allowing personnel to better observe whether bubbles are generated. Therefore, this design not only saves manpower but also facilitates bubble observation.

[0009] Preferably, a guide plate is fixedly connected to the clamp, the axis of the guide plate is aligned with the axis of the sealing ring, a collection port is opened at the top of the guide plate, a rectangular groove on the observer surrounds the collection port, and a connecting groove is opened at the bottom of the guide plate.

[0010] It's easy to understand that the contact area between the steel plate and the sealing ring is relatively large. Furthermore, it's necessary to consider that the bubbles don't rise vertically; their upward trajectory is disrupted by the internal structure, resulting in a chaotic rise. Therefore, a larger observer is needed to completely cover the top of the contact area between the steel plate and the sealing ring. Also, with a large observer, bubbles struggle to aggregate when they reach the bottom of the rectangular groove, leading to dispersion and making smaller bubbles difficult to observe. This design addresses this by fixing a guide plate to the fixture, with its axis aligned with the sealing ring's axis. When bubbles form on the sealing ring, they rise along the guide plate, eventually converging at the bottom to form a collection port. The observer only needs to cover this collection port to collect all bubbles generated on the sealing ring, eliminating the need for a large observer and making the structure more compact. The smaller observer also facilitates bubble accumulation, allowing for better bubble observation and ensuring accurate detection.

[0011] Preferably, the observer includes a fixed part and a sliding part. The fixed part is detachably installed between two clamps and completely encloses the collection port. The sliding part is slidably connected inside the fixed part and has an exhaust port. An exhaust block is slidably connected inside the sliding part. A screw is rotatably connected to the fixed part. A rotating plate is fixedly connected to one end of the screw, and the other end of the screw passes through the exhaust port and is rotatably connected to the exhaust block. A sealing ring three is provided on the screw, and a contact surface is provided on one side of the exhaust port. The diameter of the sealing ring three is larger than the diameter of the contact surface, and the sealing ring three contacts the contact surface.

[0012] It's easy to understand that before testing, the air inside the observer needs to be completely purged. However, due to the small size of the testing pool, purging the air from the observer is inconvenient. Furthermore, once the air is purged, the observer is submerged in water, making it difficult for staff to observe air bubbles due to the water level. Therefore, this design incorporates a fixed part and an venting block. Before testing, the fixed part is directly attached to the collection port, and the testing pool is filled with water, ensuring the water level is 2mm above the top of the sliding part. Since the sliding part has an vent, it is filled with water, and the air has been purged. Simply rotating the rotating plate on the screw causes the screw to move the venting block upwards, allowing water to drain from the vent. After the screw moves a certain distance, the sealing ring on the screw contacts the venting end face. As the screw continues to rotate, it moves the sliding part along with it. Because the vent is blocked by the sealing ring three times, the water inside the sliding part cannot be discharged. The sliding part then lifts the water out of the testing pool. When observing bubbles, staff can directly observe whether there are bubbles inside the vent block outside the water surface, thus judging the sealing effect. Even if the sealing ring three is not completely sealed during the process of the sliding part pumping water up, causing bubbles to enter the sliding part, some bubbles will remain between the vent block and the sliding part due to buoyancy, and will not enter the vent block. The bubbles inside the vent block will only be those collected by the sealing ring. Therefore, this design not only allows the observer to better expel internal air, thus avoiding interference with subsequent observation, but also allows the observer to pump water up, enabling staff to observe from outside the water surface.

[0013] Preferably, the detection cell includes a left detection cell and a right detection cell. The left detection cell is slidably connected to the left electrolytic cell, and the right detection cell is slidably connected to the right electrolytic cell. A second sealing ring is provided on the right detection cell, and the second sealing ring is in contact with the left detection cell. A locking block is fixedly connected to the right detection cell, and a locking groove is provided on the left detection cell.

[0014] As is easily understood, this design divides the test pool into a left test pool and a right test pool. When not in use, the left and right test pools can be slid to the sides and away from the clamp. This avoids the presence of the test pools affecting the installation of the steel plate. After the test is completed, the left and right test pools can be separated, making it easier to drain the water inside them, thereby improving test efficiency and speed.

[0015] Preferably, a first separation plate is fixedly connected to the fixing part, and a second separation plate is slidably connected to the exhaust block. The first separation plate and the second separation plate are slidably connected, and the first separation plate is in contact with the steel plate.

[0016] As is easily understood, when performing a seal test, the detection component needs to apply pressure to the left and right electrolytic cells on both sides via a piston. Simultaneous testing is not possible; otherwise, when bubbles are generated, it's impossible to determine which side of the steel plate they originated from, thus reducing the testing speed. This design addresses this by fixing a first separation plate to the fixed part and sliding a second separation plate to the exhaust block. The first separation plate divides the collection port into two sides, while the second separation plate divides the interior of the exhaust block into two sides. Since the first separation plate is in contact with the steel plate, bubbles generated on both sides of the steel plate are collected on the respective sides of the exhaust block. At this point, the operator only needs to observe which side of the exhaust block has bubbles to determine which side of the steel plate has a sealing problem. This allows for simultaneous seal testing on both sides of the steel plate, thereby improving the detection speed of the detection component.

[0017] Preferably, a baffle is fixedly connected to the right detection pool, a flow guide groove is provided on the baffle, and flow guide arc surfaces are provided on both sides of the flow guide groove. The two sides of the flow guide groove extend to the outside of the right detection pool. The center of the flow guide groove is aligned with the two contact points of the left detection pool and the sealing ring. A barrier plate is fixedly connected to the sliding connection points of the right detection pool and the left detection pool with the right electrolytic pool and the left electrolytic pool respectively. A barrier groove is provided on the barrier plate.

[0018] As is easily understood, since the testing pool is divided into a left testing pool and a right testing pool, and the left and right testing pools are sealed only by a single sealing ring 2, if the seal is not tight, air bubbles will be generated at the location of sealing ring 2. If these air bubbles enter the guide plate, they will travel along the guide plate into the exhaust block, leading to misjudgment by the operator during the sealing test. Therefore, this design uses a baffle fixedly connected to the right testing pool, with a guide groove on the baffle. The center of the guide groove is aligned with the contact point between the left testing pool and sealing ring 2. When air bubbles are generated at sealing ring 2, they are blocked by the inside of the guide groove and rise to the surface along the inside of the guide groove. Thus, this design avoids air bubbles generated at sealing ring 2 affecting the operator's judgment of the sealing performance of sealing ring 2, thereby improving the accuracy of the testing components.

[0019] A method for testing the anti-scaling properties of enamel-lined steel plates, the specific testing steps of which are as follows: S1. First, clamp the steel plate to be tested between the clamps on the left and right electrolytic cells and reinforce it. Then push the left and right detection cells on both sides and make the card block on the left detection cell enter the card slot on the right detection cell and squeeze it onto the sealing ring two on the right detection cell. S2. Fix the observer between the two clamps and start adding water to the detection pool until the water level is 2mm above the top of the sliding part; S3. Rotate the rotating blade on the screw. The screw will drive the exhaust block to move upward. The exhaust block will then drive the separation plate two to move. At this time, the water on the top of the exhaust block will be discharged from the exhaust port. After the screw moves a certain distance, the sealing ring three on the screw will contact the end face of the exhaust port. At this time, continue to rotate the screw. The screw will then drive the sliding part to move together. At this time, because the exhaust port is blocked by the sealing ring three, the water inside the sliding part cannot be discharged. At this time, the sliding part will lift the water inside the test pool to the water surface. At this time, stop rotating the rotating blade. S4. Start applying pressure to the two pistons. At this time, the staff can start to observe whether there are air bubbles inside the exhaust block located outside the water surface, and then judge the sealing effect. If there are air bubbles inside the exhaust block, it means that there is a leak in the seal between the left or right electrolytic cell and the steel plate. At this time, the steel plate must be removed and the sealing problem must be checked. After the problem is investigated, the sealing of one side is tested until there are no air bubbles on both sides of the exhaust block. S5. After completing the sealing test, electrolyte is added to the left and right electrolytic cells. The left electrolytic cell is the hydrogen-filling area. Cathodic polarization is applied by a galvanometer to generate hydrogen atoms that penetrate into the steel plate. The right electrolytic cell is the detection area. An anodic potential is applied by a potentiostat to oxidize the hydrogen atoms that diffuse to the right side into hydrogen ions, generating a detectable anodic current. Finally, the diffusion rate of hydrogen ions on the steel plate is calculated, and the anti-scaling performance of the enamel steel plate is further calculated.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention incorporates a detection component on a hydrogen permeation cell device. When two clamps clamp the steel plate, the detection cell is filled with water. Pressure is then applied to the pistons on both sides. If the seal ring is not properly sealed to the steel plate, air bubbles will form at the seal. By observing whether air bubbles are formed, the sealing effect between the steel plate and the seal ring can be determined, reducing the detection time. Furthermore, it eliminates the need to add other solutions to the left and right electrolytic cells, thus avoiding the cleaning steps required before subsequent testing and simplifying the operation. Therefore, this design improves the detection rate of sealing performance and simplifies the detection process.

[0021] 2. This invention incorporates an observer inside the detection pool. When bubbles are present, they rise and enter the observer, settling at the bottom of the rectangular groove. This design allows for the collection of bubbles generated at any leakage point between the steel plate and the sealing ring. This enables operators to determine the sealing effect simply by observing the presence of bubbles inside the observer. Furthermore, when the leakage point is small and the bubbles are small, the observer can continuously collect bubbles, causing them to accumulate at the bottom of the rectangular groove, thus providing better observation of bubble formation. Therefore, this not only simplifies operation but also facilitates the observation of bubbles by operators, ensuring the accuracy of the detection.

[0022] 3. This invention features a guide plate fixedly connected to a fixture, with the axis of the guide plate aligned with the axis of the sealing ring. When bubbles are generated on the sealing ring, they rise along the guide plate, eventually converging at the bottom to form a collection port. The observer only needs to wrap around the collection port to collect all the bubbles generated on the sealing ring, eliminating the need for a large observer and making the structure more compact. The smaller size of the observer also facilitates bubble accumulation, allowing for better bubble observation. Attached Figure Description

[0025] This invention provides a device and method for detecting the anti-scaling properties of enamel-lined steel plates, the technical solution of which is as follows: Please see Figures 1 to 6 A device for detecting anti-scaling of enamel steel plates includes a hydrogen permeation cell 1, which includes a left electrolytic cell 2 and a right electrolytic cell 3.

The fixed part 16 is detachably installed between the two clamps 5. In this configuration, the fixed part 16 completely encloses the collection port 14, and the sliding part 17 is slidably connected inside the fixed part 16. The sliding part 17 has an exhaust port 19, and an exhaust block 18 is slidably connected inside the sliding part 17. A screw 20 is rotatably connected to the fixed part 16. One end of the screw 20 is fixedly connected to a rotating plate 21, and the other end of the screw 20 passes through the exhaust port 19 and is rotatably connected to the exhaust block 18. A sealing ring 22 is provided on the screw 20, and a contact surface 33 is provided on one side of the exhaust port 19. The diameter of the sealing ring 22 is larger than the diameter of the contact surface 33, and the sealing ring 22 contacts the contact surface 33.

[0027] Please see Figures 1 to 6 The detection cell 8 includes a left detection cell 23 and a right detection cell 24. The left detection cell 23 is slidably connected to the left electrolytic cell 2, and the right detection cell 24 is slidably connected to the right electrolytic cell 3. A second sealing ring 25 is provided on the right detection cell 24, and the second sealing ring 25 contacts the left detection cell 23. A locking block 31 is fixedly connected to the right detection cell 24, and a locking groove 32 is provided on the left detection cell 23. A first separation plate 26 is fixedly connected to the fixing part 16, and a second separation plate 27 is slidably connected to the exhaust block 18. The first separation plate 26 and the second separation plate 27 are connected together. The sliding connection is such that the separation plate 26 contacts the steel plate 7. A baffle 28 is fixedly connected to the right detection pool 24. A guide groove 29 is provided on the baffle 28. A guide arc surface 30 is provided on both sides of the guide groove 29. The two sides of the guide groove 29 extend to the outside of the right detection pool 24. The center of the guide groove 29 is aligned with the contact point between the left detection pool 23 and the sealing ring 25. A barrier plate 28 is fixedly connected to the sliding connection between the right detection pool 24 and the left detection pool 23 and the right electrolytic pool 3 and the left electrolytic pool 2, respectively. A barrier groove 35 is provided on the barrier plate 34.

[0028] A method for testing the anti-scaling properties of the above-mentioned enamel-lined steel plate, comprising the following testing steps: Please see Figures 1 to 7The steel plate 7 to be tested is clamped between the clamps 5 on the left electrolytic cell 2 and the right electrolytic cell 3 and reinforced. At this time, the left detection cell 23 and the right detection cell 24 on both sides are slid, and the left detection cell 23 is squeezed onto the sealing ring 25 on the right detection cell 24. At this time, the left detection cell 23 and the right detection cell 24 enclose the steel plate 7 and the two clamps 5. The observer 11 is fixed between the two clamps 5. At this time, the separation plate 26 contacts the steel plate 7. Water is added to the detection cell 8 so that the water level is 2mm above the top of the sliding part 17. At this time, because the sliding part 17 has an exhaust port 19, the sliding part 17 is filled with water. The part is filled with water and the air is expelled. When the rotating plate 21 on the screw 20 is rotated, the screw 20 will move the vent block 18 upwards. The vent block 18 will then move the separation plate 27. Water at the top of the vent block 18 will be discharged from the vent port 19. After the screw 20 has moved a certain distance, the sealing ring 22 on the screw 20 will contact the end face of the vent port 19. Continuing to rotate the screw 20 will cause it to move the sliding part 17 as well. Since the vent port 19 is blocked by the sealing ring 22, the water inside the sliding part 17 cannot be discharged. The sliding part 17 will then expel the water inside. Raise the water level above test tank 8, stop rotating the rotating plate 21, and apply pressure to the two pistons 10. At this point, the operator can observe whether there are air bubbles inside the vent block 18 located outside the water surface to determine the sealing effect. If there are air bubbles on the left side of vent block 18, it indicates a leak in the seal between the left electrolytic cell 2 and the steel plate 7. If there are air bubbles on the right side of vent block 18, it indicates a leak in the seal between the right electrolytic cell 3 and the steel plate 7. If there are air bubbles on both sides of vent block 18, it indicates leaks in the seals between both the left and right electrolytic cells 2 and the steel plate 7. If any of these situations occur, the steel plate must be removed. 7. Remove and inspect the sealing problem. After the problem is identified, test the sealing on one side until there are no bubbles on either side of the exhaust block 18. At this time, add electrolyte to the left electrolytic cell 2 and the right electrolytic cell 3. The left electrolytic cell 2 is the hydrogen charging area. Apply cathodic polarization through a constant current meter to generate hydrogen atoms that penetrate into the steel plate 7. The right electrolytic cell 3 is the detection area. Apply anodic potential through a constant potential meter to oxidize the hydrogen atoms that diffuse to the right side into hydrogen ions, generating a detectable anodic current. Finally, calculate the diffusion rate of hydrogen ions on the steel plate 7, and further calculate the anti-scaling performance of the enamel steel plate 7.

At this time, push the left test cell (23) and the right test cell (24) on both sides, and make the card block (31) on the left test cell (23) enter the card slot (32) on the right test cell (24) and squeeze it onto the sealing ring two (25) on the right test cell (24); S2. Fix the observer (11) between the two clamps (5) and start adding water to the detection pool (8) until the water level is above the top of the sliding part (17) by a set distance; S3. Rotate the rotating plate (21) on the screw (20). The screw (20) will drive the exhaust block (18) to move upward. The exhaust block (18) will then drive the separation plate (27) to move. At this time, the water on the top of the exhaust block (18) will be discharged from the exhaust port (19). When the screw (20) moves, the sealing ring (22) on the screw (20) will contact the end face of the exhaust port (19). At this time, continue to rotate the screw (20). The screw (20) will then drive the sliding part (17) to move together. At this time, because the exhaust port (19) is blocked by the sealing ring (22), the water inside the sliding part (17) cannot be discharged. At this time, the sliding part (17) will lift the water inside it out of the water surface on the detection pool (8). At this time, stop rotating the rotating plate (21). S4. Start applying pressure to the two pistons (10). At this time, the staff can start to observe whether there are air bubbles inside the exhaust block (18) located outside the water surface, and then judge the sealing effect. If there are air bubbles inside the exhaust block (18), it means that there is a leak in the seal between the left electrolytic cell (2) or the right electrolytic cell (3) and the steel plate (7). At this time, the steel plate (7) is removed and the sealing problem is checked. After the problem is investigated, the sealing performance of one side is tested until there are no air bubbles on both sides of the exhaust block (18). S5. After completing the sealing test, electrolyte is added to the left electrolytic cell (2) and the right electrolytic cell (3), and the anti-explosion performance of the enamel steel plate (7) is tested.
