Description

Technical Field

[0001] This invention relates to the field of online detection technology for clay sand, specifically to an online detection device for clay sand used in sand treatment. Background Technology

[0002] In the foundry industry, the properties of clay sand (especially compaction and permeability) are key factors determining casting quality. Traditionally, the testing of these properties of clay sand has relied on manual sampling and offline laboratory testing. Operators need to manually complete a series of steps, including sampling, sample preparation, hammering, and measurement. This process is not only inefficient and time-consuming, but the test results are also easily affected by human factors such as operator experience and technique, leading to poor data repeatability and large errors. It is difficult to provide timely and accurate feedback on the true state of clay sand on the production line, and it cannot meet the needs of modern foundry production for process control and online quality monitoring.

[0003] To address the aforementioned issues, some automated or semi-automated devices for testing the properties of clay sand have emerged in recent years.

[0004] Even in devices that integrate multiple testing functions, the individual testing modules (such as sample preparation, impact testing, and air permeability testing) are often fragmented in their workflow. For example, after completing the compaction test, the sample needs to be manually or mechanically removed and then placed into the air permeability testing station. This non-integrated process not only increases the total time required for a single test but also makes it difficult to perform continuous and rapid multi-parameter testing on the same sample, hindering truly efficient online real-time testing. This phenomenon has become a problem that urgently needs to be solved by those in the field. Summary of the Invention

[0028] The feeding mechanism includes a conveying component and a discharging component. The conveying component includes a second motor 4 and a screw conveyor 12.

[0029] The discharge assembly includes a tilting plate 15, a discharge port is provided on the partition plate 13, the tilting plate 15 is located inside the discharge port and is connected to the inner wall of the discharge port by a bearing, the bottom of the housing 1 is conical, and two sets of fifth cylinders 14 are fixed on the conical side of the bottom of the housing 1, and the fifth cylinders 14 are hinged to the tilting plate 15.

[0030] The online detection system includes a vision acquisition module, a gas acquisition module, and a calculation module. The vision acquisition module is electrically connected to the vision unit, the gas acquisition module is electrically connected to the fixed gas source 34, and the calculation module includes a timing unit.

[0031] Example 1: This example improves the detection efficiency of clay sand.

[0032] The sand feeding assembly is activated to control the external clay sand to enter the shell 1. After being crushed by the mixing assembly, it falls onto the partition 13. The second motor 4 is activated to drive the screw conveyor 12 to work, so that the clay sand is turned back and forth above the partition 13.

[0033] Since the initial state of the sample preparation component is below the partition 13, that is, the extension of the second cylinder 22 causes the sample preparation barrel 16 to be located below the partition 13, and the surface of the sample preparation barrel 16 is flush with the surface of the partition 13.

[0034] When the spiral stirring rod 10 is working, it will cause clay sand to fall into the sample preparation barrel 16. When the vision unit detects that the sample preparation barrel 16 is full of clay sand, it controls the electric slide rail to move the baffle 26, so that the baffle 26 is inserted into the sample preparation plate 23, scraping off the clay sand on the surface of the sample preparation barrel 16, and then pushing it into the slide groove 25. It then falls into the bottom of the shell 1 along the through groove 24, smoothing the clay sand on the surface of the sample preparation barrel 16 for subsequent testing. Then, the baffle 26 is controlled to move away from the sample preparation barrel 16.

[0035] At this point, the visual unit captures an image of the clay sand on the sample preparation container 16 at the initial position of the scale line, transmits it to the visual acquisition module to record it, and marks it as h0. The second cylinder 22 is activated to retract, causing the sample preparation barrel 16 to move upward and the sample preparation plate 23 to be removed. The fourth cylinder 6 is then activated to extend, causing the pressing component 17 and the hammer component 18 to move downward and hammer the clay sand three times. The position of the clay sand on the scale line is then photographed again by the vision unit and marked as h1. The compaction rate of the clay sand is detected by the calculation unit. The formula is: h = (h0 - h1) / h0 * 100%, where h represents the compaction rate of the clay sand. Since the calculation unit sets the range of the compaction rate under normal conditions, when h is not within the set range, it indicates that there is a problem with the compaction rate of the clay sand. When h is within the set range, it indicates that the compaction rate of the clay sand is qualified.

[0036] After the compaction rate of clay sand is tested, the image of the clay sand sample surface is monitored in real time by the vision unit and transmitted to the vision acquisition module as the base image, which improves the accuracy of subsequent air permeability testing.

[0037] To test the air permeability of the clay sand, the sample preparation container 16 is returned to its original position, and the baffle 26 is inserted into the chute 25, blocking the surface of the sample preparation container 16. The third cylinder is activated to push the push plate 27 upward, controlling the compacted clay sand to move upward within the sample preparation container 16 and contact the surface of the baffle 26. Then, the pressing element 17 is moved downward, causing the pressing plate 33 to contact the surface of the baffle 26. Since the ejector tube 32 is higher than the baffle 26, the position of the ejector tube 32 above the baffle 26 passes through the sealing plate 30 and enters the conical hole 29, subsequently connecting with the air tube 31.

[0038] The fixed gas source 34 is activated to transmit the internal gas through the connecting pipe to the gas pipe 31, and then through the gas pipe 31 into the ejector tube 32, and then the gas is transmitted to the sample preparation container 16. After passing through the clay sand, the gas flows out from the vent in the push plate 27.

[0039] Since the gas inside the fixed gas source 34 has a fixed volume and has been recorded in the gas acquisition module, when the fixed gas source 34 is working, the timing unit starts timing until the gas inside the fixed gas source 34 is used up, and the time length t is recorded. The normal time range is set in the calculation module. When t is not within the set time range, it indicates that the clay sand has poor air permeability. When t is within the set time range, it indicates that the clay sand has good air permeability.

[0040] Through the above steps, the compaction rate and air permeability of clay sand can be tested using a single device, achieving integrated testing without the need to change devices, thus improving testing accuracy and saving testing time and improving testing efficiency.

[0041] In order to further improve the accuracy and reliability of air permeability detection results, after the gas in the fixed air source 34 is completely discharged, the baffle 26 is controlled to move away from the open end of the sample preparation barrel 16, then the image of the upper surface of the clay sand sample is collected again by the visual unit, transmitted to the visual acquisition module, and compared with the reference image collected before detection.

[0042] If the comparison result shows that local bulges, cracks or other structural defects appear on the upper surface of the sample, it indicates that uneven deformation or local damage occurred inside the sample caused by the airflow during the air permeability detection process. This condition will interfere with the normal seepage path of the gas, thereby affecting the measurement accuracy of the air permeability duration. In this case, the current air permeability detection data is determined to be invalid, and the sample is determined to have internal structural defects.

[0043] Then the pushing plate 27 is controlled to move upward to push the clay sand in the sample preparation barrel 16 out onto the partition plate 13. The screw conveying rod 12 is continuously controlled to operate to re-stir the clay sand on the partition plate 13, and the test of the compactability and air permeability of the clay sand is repeated. This process is repeated multiple times. If the compactability and air permeability are qualified in multiple consecutive tests, it indicates that the quality of the clay sand is qualified. The fifth air cylinder 14 is controlled to contract, so that the turnover plate 15 turns downward and no longer blocks the main discharge port, and the clay sand flows out from the discharge port and then out of the housing 1, completing the clay sand test.

[0044] It should be supplemented that when the pushing plate 27 pushes the clay sand out of the sample preparation barrel 16, in order to prevent the clay sand adhered to the pushing plate 27 from affecting the next test, when the upper surface of the pushing plate 27 is flush with the surface of the sample preparation barrel 16, the baffle 26 is controlled to move close to the surface of the sample preparation barrel 16 again, and then contacts the surface of the pushing plate 27, which can scrape off the clay sand adhered to the surface of the pushing plate 27, ensuring the accuracy of the next test.

[0045] In the second embodiment, the detection quality is further improved in this embodiment based on the first embodiment.

[0046] Specifically, after the air permeability detection is completed, the position of the scale line corresponding to the upper surface of the clay sand sample in the sample preparation barrel 16 is collected again by the visual unit, which is recorded as the secondary height value h2. The calculation module compares h2 with the height value h1 after hammer compaction. When h2=h1, it indicates that no particle slip or structural subsidence caused by airflow occurred inside the sample during the air permeability detection process, and the height of the sample remains stable. Accordingly, it is determined that the clay sand after three times of hammering has sufficient compactness. When h2<h1, it indicates that during the air permeability test, the airflow significantly disturbs the internal structure of the sample, causing particle rearrangement or decreased compactness, thereby changing the height of the sample. This phenomenon reflects that the compactness of the sample is insufficient after three times of hammering, and the air permeability detection result has been distorted. Therefore, the current detection data is determined to be invalid and will not be included in subsequent analysis and calculation.
