[0002] In the isostatic graphite production process, the quality inspection of the calcined product formed after the green blank is calcined is crucial, directly affecting the performance and application of subsequent products. Traditional hammer testing methods rely excessively on the personal experience of the inspectors, and are greatly influenced by subjective factors, making it easy to make misjudgments and difficult to guarantee the accuracy of the test results. While some methods using ultrasonic instruments improve the objectivity of the inspection to a certain extent, the testing speed is slow and the efficiency is low, which cannot meet the needs of rapid testing of large batches of calcined products on the production site.

[0003] Currently, there are many problems in the testing of isostatically pressed graphite calcined products:

[0004] Existing testing equipment also has structural design flaws. Most of its testing components are integrated designs, lacking a modular structure. When a component is damaged, the individual damaged part cannot be replaced; the entire component must be replaced. This significantly increases maintenance costs and, due to the cumbersome and time-consuming disassembly and assembly process, severely impacts testing efficiency, making it difficult to adapt to the rapid testing pace of production lines.

[0039] Back-end inspection: After the roasted product passes through the inspection frame, the telescopic rod 41 pushes down the right upright plate 42 and moves it down. The inspection component 7 on its side wall scans and inspects the back end of the roasted product. After the inspection is completed, the telescopic rod 41 lifts up the right upright plate 42 to reset, completing the inspection of each side of the roasted product.

[0040] III. Installation and Removal of Detection Component 7 (Modular Design)

[0041] Installation process:

[0042] By using the engagement of the locking block 61 and the locking slot 63, the cover 6 is installed in the groove 62, so that it covers the outside of the multiple equally spaced detection components 7.

[0043] Push the detection component 7 into the groove 75 so that the front insert 73 is inserted into the slot 74, and then install it between the side plate 1 71 and the side plate 2 72.

[0044] After the cover 6 is inserted into the groove 62, its inner sides are tightly attached to the side walls of side plate 1 71 and side plate 2 72, and the inner side wall is tightly attached to the rear end of the detection component 7, forming a barrier for the detection component 7, thus completing the installation.

[0045] Disassembly process: Pull the cover 6 to separate the locking block 61 from the locking slot 63, pull the detection component 7 to separate the insertion block 73 from the slot 74, and then pull it out from the push groove 75 to remove the detection component 7.

[0046] Modular advantages: The detection component 7 consists of multiple independent modules. When a component is damaged, only the damaged part needs to be replaced, which greatly saves costs compared to an integrated detection component.

[0047] IV. Defect Identification and Display Unit:

[0048] Real-time display: The signals acquired and processed by each channel are displayed in real time as graphs, such as impedance plane diagrams and amplitude / phase-position curves.

[0049] Threshold comparison: The processed signal characteristic parameters are compared with the preset qualified threshold range.

[0050] Defect Alarm / Indication: When the signal characteristic parameters of any channel exceed the preset threshold range, an audible and visual alarm is triggered or a clear mark is made on the display image at the corresponding position of the channel, such as highlighting or color changing.
