Description

Technical Field

[0001] The present invention relates to the technical field of ceramic material testing, and in particular to an ozone aging chamber based on ceramic material testing. Background Art

[0002] Silicon carbide composite ceramics, as high-performance engineering materials, are widely used in aerospace, automotive, and chemical industries due to their excellent mechanical properties, high-temperature resistance, and oxidation resistance. To ensure their long-term reliability in practical applications, ozone aging testing is particularly important. Ozone aging testing is an effective method for evaluating the durability of materials in high-concentration ozone environments. It can reveal potential aging phenomena that may occur during long-term use and their impact on performance.

[0003] Currently, most laboratories and companies use ozone aging chambers to perform aging tests on silicon carbide composite ceramic materials. These devices simulate extreme ozone environments, accelerating the material's aging process, thereby shortening testing cycles and providing reliable performance evaluation data.

[0004] After searching, a Chinese patent with patent publication number CN119023553A was found, which is an ozone aging box for ceramic materials, including: a box body; the box body is a rectangular box structure, a rectangular plate-shaped placement plate is welded in the box body, and three composite ceramic materials are placed on the placement plate.

[0005] Although the above patent can effectively perform aging tests on silicon carbide composite ceramic materials, it still has the following shortcomings in practical applications: 1. Ozone exhaust takes a long time: After each test, the door must be opened to remove the test sample. Because ozone is harmful to human health, the ozone in the chamber must be completely exhausted before opening the equipment to remove the sample. This process often requires complex exhaust steps and monitoring of ozone concentration until it reaches a safe level. This is not only time-consuming, but also may cause ozone residue due to equipment failure or operational errors, further extending the waiting time.

[0006] 2. Serious waste of resources: During each ozone emptying process, a large amount of ozone is directly discharged into the atmosphere. Even with an ozone decomposition device, this will cause a certain amount of resource waste. In addition, frequent emptying operations increase operating costs and reduce testing efficiency.

[0007] 3. Limited test continuity: Each time a sample is removed, the test process must be interrupted to complete ozone evacuation and sample replacement, making the entire test cycle discontinuous. This intermittent testing method may reduce the continuity and integrity of data collection and affect the accuracy of test results. Summary of the Invention

A rotating shaft 5 is rotatably connected to the cylinder 4. The left and right ends of the rotating shaft 5 extend to the outside of the frame 1. Four rotating plates 6 located in the cylinder 4 are evenly spaced along the circumference of the rotating shaft 5. A sealing strip 61 is connected to the side of the rotating plate 6 away from the rotating shaft 5 for sealing the gap between the rotating plate 6 and the inner wall of the cylinder 4 to prevent ozone from leaking from the gap between the rotating plate 6 and the inner wall of the cylinder 4. Two lifting brackets 7 are symmetrically provided on the bottom surface of the frame 1 with the belt conveyor 3 as the symmetrical center. They are used to lift the sample into the cylinder 4.

[0034] See also Figure 6-Figure 8 The clamping mechanism includes a slotted splint 81 and an electric push rod 82 hinged on the rotating plate 6. The telescopic rod of the electric push rod 82 is hinged to the slotted splint 81. The slots on the two adjacent slotted splints 81 are staggered left and right to avoid mutual collision and obstruction of the clamping of the sample when swinging to clamp the sample. Rubber splints 83 are connected at intervals on the clamping parts of the slotted splints 81. The rubber splints 83 can not only increase the friction between the slotted splints 81 and the sample, ensuring that the slotted splints 81 clamp the sample more firmly, but also provide buffering protection for the sample to avoid the sample being directly squeezed and deformed by the slotted splints 81. A telescopic sleeve 80 for covering the electric push rod 82 is connected between the rotating plate 6 and the slotted splint 81 to cover and protect the electric push rod 82 to prevent the electric push rod 82 from being corroded by ozone.

[0035] See also Figure 3 and Figure 8 The gripping mechanism includes two rodless cylinders 91 installed on the right side of the box body 20. A lifting plate 92 is connected between the moving bodies of the two rodless cylinders 91. The bottom of the lifting plate 92 is connected to a guide rail 93. Two left and right clamping plates 94 are slidingly provided in the guide rail 93. A bidirectional screw motor 95 is provided on the guide rail 93. The bidirectional screw on the bidirectional screw motor 95 is threadedly connected to the clamping plate 94 to drive the two clamping plates 94 to move closer to and away from each other.

[0036] See also Figure 4 , a cylinder 2 16 is embedded in the left side of the frame 1, and a seal 17 located in the frame 1 is installed on the piston rod of the cylinder 2 16, and the seal 17 is engraved with the word "defective product".

[0037] First, the belt conveyor 3 is controlled to operate, driving the carrier block 31 to carry the silicon carbide composite ceramic material sample backward until it is aligned with the lifting bracket 7. Then, the cylinder 1 71 is controlled to drive the L-shaped plate 72 to drive the electric wheel 73 and the driven wheel 74 to move upward, thereby lifting the sample upward into the cylinder 4. The sample is then located between the two front and rear turntables 6 on the lower side. Next, the electric push rod 82 on the two front and rear turntables 6 on the lower side is controlled to operate to push the slotted clamping plate 81 on the two front and rear turntables 6 on the lower side to swing toward the sample, thereby clamping the sample. The rotating shaft 5 is then manually driven to drive the turntable 6 to rotate 180 degrees, thereby rotating the sample upward. Then, the rodless cylinder 91 is controlled to drive the lifting plate 92 downward, thereby driving the clamping plate 94 downward through the guide rail 93 into the cylinder 4 and aligning it with the sample. The electric push rod 82 is then controlled to work, pulling the slotted clamping plate 81 to swing back to release the sample. The bidirectional screw motor 1 95 is then controlled to drive the two clamping plates 94 to move closer together to clamp the sample. The rodless cylinder 91 is then controlled to drive the lifting plate 92 upward, thereby moving the sample above the driven roller 12 and the motorized wheel 73. The bidirectional screw motor 2 14 is then controlled to drive the two sliders 11 closer together, thereby bringing the driven roller 12 and the motorized wheel 73 closer together. The bidirectional screw motor 1 95 is then controlled to drive the two clamping plates 94 away from each other to release the sample, and the sample then falls onto the driven roller 12 and the motorized wheel 73.

[0038] Ozone is injected into the box 20 through the gas injection pipe 21. Ozone contacts the silicon carbide composite ceramic material sample, and the silicon carbide composite ceramic material sample is subjected to ozone aging testing. The electric roller 13 is controlled to drive the sample to rotate, ensuring that all parts of the sample can fully contact the ozone and avoid detection blind spots. During the detection process, the rodless cylinder 91 is controlled to drive the clamping plate 94 downward to contact the sample, and then the bidirectional screw motor 95 is controlled to drive the two clamping plates 94 toward and away from each other to rub the sample, thereby realizing the detection of the silicon carbide composite ceramic material sample in contact with ozone in the friction state, thereby improving the detection range of the silicon carbide composite ceramic material sample. The sample can be blocked by the annular block 121 to prevent the sample from falling from the electric roller 13 and the driven roller 12.

[0039] After the ozone aging test of the sample is completed, the bidirectional screw motor 1 95 is first controlled to drive the two clamping plates 94 to clamp the sample, and then the bidirectional screw motor 2 14 is controlled to drive the two sliders 11 away from each other, so that the driven roller 12 and the electric roller 13 move away from each other to avoid the sample. Next, the rodless cylinder 91 is controlled to drive the lifting plate 92 to move downward, thereby driving the sample to move down between the front and rear turntables 6 located on the upper side. Then, the electric push rod 82 is controlled to drive the slotted clamp 81 to clamp the sample. Then, the rotating shaft 5 is manually driven to drive the turntable 6 to rotate 180 degrees, thereby rotating the tested sample downward. Then, the electric push rod 82 is controlled to drive the slotted clamp 81 to release the sample. The sample is then placed on the electric wheel 73 and the driven wheel 74. Then, the cylinder 1 71 is controlled to drive the L-shaped plate 72 to drive the electric wheel 73 and the driven wheel 74 downward, thereby driving the sample down to the carrier block 31. During this process, the camera 41 on the cylinder 4 and the L-shaped plate 72 captures the inspected sample, which is then transmitted to the backend terminal for display and analysis, thereby achieving visual inspection of the silicon carbide composite ceramic material sample after ozone aging testing. Simultaneously, the motorized wheel 73 is controlled to rotate the sample, achieving comprehensive inspection of the sample. When the backend terminal detects that the sample is unqualified, the backend terminal sends a signal to the controller 24. After receiving the signal, the controller 24 controls the cylinder 2 16 to drive the seal 17 to move back and forth to the right and left. The seal 17 moves to the right to contact the sample, imprinting the word "defective product" on the sample to automatically distinguish between qualified and unqualified products, facilitating subsequent differentiation between qualified and unqualified products.

[0040] By repeating the above operation, the next round of silicon carbide composite ceramic material sample testing can be carried out. The cylinder 4 can be sealed by the rotating plate 6 to prevent the discharge of ozone in the box 20. In this way, the device not only does not need to empty the ozone in the box 20 for taking and placing samples, thereby reducing ozone waste, reducing costs, shortening waiting time, and improving test efficiency, but also supports continuous testing, thereby improving the continuity and integrity of data collection and improving the accuracy of test results.

[0041] See also Figure 3 、 Figure 4 and Figure 6The frame 1 is provided with a driving mechanism for driving the rotating shaft 5 to rotate. The driving mechanism includes a rotating shaft 151 rotatably connected to the right side of the frame 1, and a disc 152 located on the outside of the frame 1 is connected to the rotating shaft 151. A grooved wheel 153 is connected to the right side of the rotating shaft 5, and a lever 154 for driving the grooved wheel 153 to rotate is connected to the eccentric position of the disc 152. The rotating shaft 151 is connected to a gear 156 located in the frame 1 through a one-way clutch, and a rack 155 is connected to the piston rod of the cylinder 71 of the right lifting bracket 7. The rack 155 meshes with the gear 156, and a guide rod is connected to the right side of the bottom surface of the frame 1. A sliding sleeve is slidably connected to the guide rod, and the sliding sleeve is fixedly connected to the rack 155. The cooperation of the guide rod and the sliding sleeve can guide the lifting and lowering of the rack 155 to ensure that the rack 155 can be lifted and lowered smoothly.

[0042] When the piston rod of right cylinder 171 extends, it drives rack 155 upward. Due to the one-way clutch, the upward movement of rack 155 pushes gear 156 to idle without rotating shaft 151. When the piston rod of right cylinder 171 retracts, it drives rack 155 downward. Rack 155's downward movement pushes gear 156, which in turn rotates shaft 151. Rotation of shaft 151 drives disk 152 to rotate lever 154. The lever 154 rotates the grooved wheel 153 90 degrees, thereby driving shaft 5 to rotate rotating plate 6 90 degrees, thereby transporting samples to be tested upward and samples after testing downward. This eliminates the need for manual rotation of shaft 5, enabling automatic sample transport, improving automation, reducing manual operations, lowering labor intensity, and improving work efficiency.

[0043] See also Figure 8-Figure 9 An ozone recovery mechanism is provided on the frame 1, and the ozone recovery mechanism includes a vacuum pump 181 installed on the left outer wall of the frame 1. The vacuum pump 181 is connected to the cylinder 4 through an exhaust pipe 182. The right side of the cylinder 4 is connected to an air inlet pipe 183, and an electromagnetic valve 184 is installed on the air inlet pipe 183. An air supply pipe 186 is installed on the vacuum pump 181, and the air supply pipe 186 is connected to the box 20 through an air outlet pipe 185. An electromagnetic valve 2 187 is installed on the air outlet pipe 185. An activated carbon filter 188 located above the air outlet pipe 185 is installed on the air supply pipe 186 by bolts, and an electromagnetic valve 3 189 located above the activated carbon filter 188 is installed on the air supply pipe 186.

[0044] When the rotating plate 6 rotates, ozone is carried out to the area in the cylinder 4 connected to the exhaust pipe 182. Initially, the solenoid valve 1 184 and the solenoid valve 3 189 are closed, and the solenoid valve 2 187 is open. The vacuum pump 181 is controlled to operate, and the ozone in the area in the cylinder 4 connected to the exhaust pipe 182 can be transported back to the housing 20 to prevent ozone leakage, thereby recycling the ozone, further reducing ozone waste and improving safety. Subsequently, the solenoid valve 1 184 and the solenoid valve 3 189 are controlled to open, and the solenoid valve 2 187 is controlled to close. External gas enters the area in the cylinder 4 connected to the exhaust pipe 182. The external gas is blocked by the rotating plate 6 and cannot enter the housing 20. A small amount of ozone is discharged from the air supply pipe 186 and filtered and decomposed by the activated carbon filter 188. When ozone needs to be recycled again, the solenoid valve 1 184 and the solenoid valve 3 189 are controlled to close, and the solenoid valve 2 187 is controlled to open.
