Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ignition residue detection, and in particular to a cavity structure for ignition residue detection, a detection system and a method. BACKGROUND

[0002] The statements in this section merely provide background technology related to the present application and do not necessarily constitute prior art.

[0003] In the field of ignition residue detection, accurately determining the content of the residue remaining after the sample is subjected to high-temperature ignition is a key means for evaluating the purity and impurity composition of the substance, and is widely used in the quality control links of the chemical, pharmaceutical, food and other industries. The detection process has strict requirements on the temperature conditions, and usually needs to heat the sample to a high temperature of about 1000℃, so that the organic components are completely burned and decomposed, and only inorganic residues are left. However, when the traditional detection equipment implements this process, it is often limited by design defects, and it is difficult to balance the heating efficiency, temperature uniformity and temperature stability, resulting in long detection time and large result deviation, which not only affects the detection efficiency, but also may mislead the judgment of the sample quality. The specific problems include: (1) The weighing system of the traditional ignition residue detection equipment usually uses a balance lever connected with the inside of the high-temperature furnace. The high-temperature furnace usually uses a high temperature of 1000℃, and there is thick smoke and sulfuric acid evaporation. The entire detection process requires high-precision weighing, and the constant weight of the test cup body is required for two-time weighing (i.e. the weight difference of the test cup body measured twice is less than 0.3mg). The current way of connecting the balance lever with the inside of the high-temperature furnace not only fails to meet the requirements of high-precision weighing, but also damages the balance through the balance lever and pipeline due to high temperature, sulfuric acid and thick smoke; (2) The traditional ignition residue detection equipment usually adopts a single cavity structure, and the heating element layout is unreasonable. The heat is easily lost through the cavity wall, resulting in a long time-consuming process from room temperature to 1000℃. Not only does this reduce the detection efficiency, but it also may cause changes in the composition of the sample during the pretreatment stage due to long-time heating. The temperature field distribution in the single cavity is uneven, the temperature near the heating element is high, and the temperature far away is low, so that the same batch of samples are heated to different degrees, causing incomplete or excessive ignition of the residue, which directly affects the repeatability of the detection results; (3) The traditional ignition residue detection equipment lacks effective environmental isolation design. External temperature fluctuations, air flow changes and other factors easily interfere with the temperature stability in the cavity, resulting in low temperature control accuracy and difficulty in stable maintenance of the target temperature of 1000℃, further amplifying the detection error.

[0039] Compared with the prior art, the present application has the following beneficial effects: 1. This invention addresses the core technical challenges in the detection of ignition residues through a combination of inner and outer cavity spaces. When the inner cavity rises and seals with the top cover assembly to form the inner cavity space, its sealed environment significantly reduces heat loss. Combined with the synergistic effect of the inner cavity heating element and the top cover heating element, a three-dimensional heating field is formed, which can quickly focus energy to raise the cavity temperature to the target value of 1000℃ in a short time, effectively shortening the heating time. At the same time, the layout of the sealed space and dual heating sources makes the heat distribution more uniform, avoiding the problem of excessive local temperature differences in traditional open heating, and ensuring the consistency of the sample heating in the test cup. In addition, the buffer layer formed by the outer cavity space can reduce the impact of external environmental fluctuations on the inner cavity. Combined with the precise temperature control system, it significantly improves the temperature control accuracy. This dual-space synergistic mechanism optimizes heating efficiency, temperature uniformity, and temperature control stability simultaneously, ultimately greatly reducing detection errors and significantly improving the accuracy of ignition residue detection.

[0040] 2. The weighing component and the test chamber component of this invention are separated, which solves the problem of the influence of high temperature, sulfuric acid and dense smoke on weighing and improves the detection accuracy; the inner cavity or the upper cover insulation plate can be automatically raised and lowered, avoiding the harm to the human body caused by rapid cooling and high temperature exhaust gas; through the design of cooling pipe, electric fan and exhaust port, not only can rapid cooling be achieved, but also the smoke and acid gas emitted from the inner cavity space can be quickly discharged, and at the same time, the toxic and harmful gases generated by the insulation material at high temperature can be discharged, avoiding the harm to the human body caused by toxic and harmful gases.

[0041] 3. The upper cover assembly of the present invention has a sample placement port for adding the sample and a cup-retrieving port for taking the test cup for weighing. The opening and closing of the sample placement port is controlled by the front cover assembly, so that only part of the test cup is exposed when adding the sample. This solves the problems of inaccurate quantitative addition of the sample and inability to clean the addition tube when the test chamber is opened from the side, and avoids the influence of adding the sample on other test cups. The opening and closing of the cup-retrieving port is controlled by the cup-retrieving port cover assembly, so that only the test cup to be weighed is exposed at one time during the weighing test, avoiding the influence of weighing on other test cups. Through the above arrangement of the sample placement port and the cup-retrieving port, environmental influences are effectively avoided and the test accuracy is improved.

[0042] 4. The weighing component of the present invention includes a weighing lifting cylinder, a weighing box, a windproof cover, and a second opening drive mechanism. The opening cylinder can drive the windproof cover to slide, thereby realizing the opening and closing action of the weighing box and preventing interference from airflow when weighing the test cup. The weighing box is provided with air holes, into which positive and negative ions generated by the static eliminator are blown in to neutralize the static charge on the test cup, thereby realizing static dissipation and ensuring weighing accuracy.

[0043] 5. In this invention, when the test cups on the sample tray are arranged in double or multiple rings, a fixed ring cylinder and a gripper fixing plate are added. The gripper cylinder is fixed on the gripper fixing plate. The fixed ring cylinder can push the gripper cylinder and the gripper fixing plate to move, so that the gripper cylinder is positioned on different test cup rings, thereby gripping the test cups at different positions.

[0044] 6. The present invention adopts a scheme of one host and multiple slave devices (including the case of one slave device). Only one set of weighing component and balance component is needed to expand multiple test chambers, enabling the testing of more samples and greatly improving testing efficiency.

[0068] Based on the aforementioned integrated ignition residue detection system, this implementation proposes an integrated ignition residue detection method, specifically including the following working process: Empty cup test: Open the front cover assembly 200, place the cleaned test cup 601 into the positioning hole of the sample tray 602, close the front cover assembly 200, extend the lifting cylinder 504, causing the inner cavity 506 to rise, and the inner cavity heating element 507 and / or the upper cover heating element 405 heat and control the temperature inside the inner cavity 506 to bake and / or burn the test cup 601. After reaching the baking and / or burning temperature and time, close the inner cavity heating element 507 and / or the upper cover heating element 405, retract the lifting cylinder 504, and cause the inner cavity 506 to fall. The test cup 601 and the inner cavity 506 are exposed inside the outer cavity 502. Cooling liquid is introduced into the cooling pipe 503 to quickly cool the components inside the inner cavity 506 to room temperature, thereby quickly cooling the test cup 601. Opening the test cavity assembly 500, the rotating mechanism 600 drives the sample plate 602 to rotate the test cup to the position above the cover assembly 400; the lifting cylinder 1102 lifts up → the translation cylinder 1103 moves left → the clamping cylinder 1101 opens the clamping jaw 1106 → the lifting cylinder 1102 lowers down → the clamping cylinder 1101 closes the clamping jaw 1106 → the test cup 601 is clamped → the lifting cylinder 1102 lifts up → the translation cylinder 1103 moves right → the test cup 601 is moved to the position directly above the weighing assembly 1000 → the weighing lifting cylinder 1001 lifts up → the second cover opening cylinder 1004 opens the windproof cover 1003 → the lifting cylinder 1102 lowers down → the clamping cylinder 1101 opens the clamping jaw 1106 → the test cup 601 is placed in the weighing box 1002 → the lifting cylinder 1102 lifts up → the second cover opening cylinder 1004 closes the windproof cover 1003 → the weighing lifting cylinder 1001 lowers down → the test cup 601 is lowered with the weighing box 1002 and falls on the weighing plate of the electronic balance 902, and the weighing is performed to obtain the mass of the test cup 601, and the reverse operation is performed to place the test cup 601 back, and the rotating mechanism 600 is rotated to the next test cup 601, and the weighing of all the test cups 601 is sequentially completed. After the weighing of all the test cups 601 is completed, the test cavity assembly 500 is closed by the cup opening cover assembly 1200, and the previous lifting of the inner cavity body 506, baking and / or burning, cooling and weighing of the test cup are repeated until the mass of the test cup 601 is constant, which is recorded as the empty cup mass M1.

[0069] Test of the sample cup: The front cover assembly 200 is opened, and the sample is added to the test cup 601 with a constant mass, and the front cover assembly 200 is closed. The lifting cylinder 504 is extended to drive the inner cavity body 506 to lift up. The inner cavity heating element 507 and / or the upper cover heating element 405 heat the temperature in the inner cavity body 506 to a constant temperature, and the test cup 601 is baked and / or burned. After the baking and / or burning temperature and time are reached, the inner cavity heating element 507 and / or the upper cover heating element 405 are turned off. The lifting cylinder 504 is retracted to drive the inner cavity body 506 to lower down. The test cup and the inner cavity body 506 are exposed to the cavity shell 502. The cooling liquid is introduced into the cooling pipe 503 to rapidly cool the parts in the inner cavity body 506 to room temperature, and then the test cup 601 is rapidly cooled. The cup taking cover assembly 1200 opens the test cavity assembly 500, the rotating mechanism 600 drives the sample plate 602 to rotate the test cup to the position above the cover assembly 400; the lifting cylinder 1102 is lifted → the translation cylinder 1103 is moved left → the clamping jaw cylinder 1101 opens the clamping jaw 1106 → the lifting cylinder 1102 is lowered → the clamping jaw cylinder 1101 closes the clamping jaw 1106 → the test cup 601 is clamped → the lifting cylinder 1102 is lifted → the translation cylinder 1103 is moved right → the test cup 601 is moved to the position directly above the weighing assembly 1000 → the weighing lifting cylinder 1001 is lifted → the second cover opening cylinder 1004 opens the windproof cover 1003 → the lifting cylinder 1102 is lowered → the clamping jaw cylinder 1101 opens the clamping jaw 1106 → the test cup 601 is placed in the weighing box 1002 → the lifting cylinder 1102 is lifted → the second cover opening cylinder 1004 closes the windproof cover 1003 → the weighing lifting cylinder 1001 is lowered → the test cup 601 is lowered with the weighing box 1002 and falls on the weighing plate of the electronic balance 902, the weighing is performed, the mass of the cup is obtained, the reverse operation is performed, the test cup 601 is placed back, the rotating mechanism 600 is rotated to the next test cup 601, and the weighing of all test cups 601 is sequentially completed. After the weighing of all test cups 601 is completed, the cup taking cover assembly 1200 closes the test cavity assembly 500, and the previous lifting of the inner cavity body 506, baking and / or burning, cooling and weighing of the test cup 601 are repeated until the mass of the test cup 601 is constant, which is recorded as the sample cup mass M2.

[0070] The difference between the sample cup mass M2 and the empty cup mass M1 is recorded as the mass of the burning residue.

[0071] When the test cup 601 is arranged in a double-ring or multi-ring manner, the cup taking and weighing process is as follows: Lifting cylinder 1102 rises → translation cylinder 1103 moves to the left → gripper cylinder 1101 opens gripper 1106 → lifting cylinder 1102 descends → gripper cylinder 1101 closes gripper 1106 → clamping test cup 601 → lifting cylinder 1102 rises → translation cylinder 1103 moves to the right → test cup 601 is moved directly above weighing assembly 1000 → weighing lifting cylinder 1001 rises → second cover opening cylinder 1004 opens windproof cover 1003 → lifting cylinder 1102 descends → gripper cylinder 1101 opens gripper 1106 → test cup 601 is placed inside weighing box 1002 → lifting cylinder 1102... The process begins with the following steps: The first step involves raising the lid, then lowering the second opening cylinder 1004 to close the windproof cover 1003; the second step involves lowering the weighing lifting cylinder 1001; the third step involves lowering the test cup 601 along with the weighing box 1002 and placing it on the weighing pan of the electronic balance 902 for weighing to obtain the cup's mass; the process is reversed, and the test cup 601 is returned to its original position. The rotating mechanism 600 then moves to the next test cup 601, and the weighing of all test cups 601 on this ring is completed sequentially. The fourth step involves extending the ring-fixing cylinder 1105 to position the next test cup 601 on the ring, repeating the weighing process to complete the weighing of all test cups 601 on this ring. This process continues until all test cups 601 on all rings have been weighed.
