Description

Technical Field

[0001] The present invention relates to the technical field of analytical instruments, and in particular to an automatic industrial analyzer and a control method thereof. Background Art

[0002] Automatic industrial analyzers, which measure moisture, ash, volatile matter, and fixed carbon in traditional combustible materials such as coal and coke, are essential measuring instruments in industrial production. To prevent sample explosion, traditional automatic industrial analyzers perform ash content measurement in two stages. The first stage is the ashing process: after the sample is introduced into the analyzer, the furnace temperature is raised to 500°C ± 10°C (the ashing temperature) and maintained at this temperature for 30 minutes. The second stage is the calcination process: the furnace temperature is further raised to 815°C ± 10°C (the calcination temperature), where the sample is calcined until the mass remains constant. In other words, the furnace temperature must be maintained at both the ashing and calcination temperatures for a period of time during ash content measurement. Consequently, the same automatic industrial analyzer cannot measure the ash content of two samples introduced at different times. After the ash content of one sample is measured, the furnace temperature must be lowered to below 500°C and the temperature must be raised again before the ash content of the second sample can be measured, resulting in low test efficiency. Summary of the Invention

[0003] One of the purposes of the present invention is to provide an automatic industrial analyzer that can realize parallel testing of different groups of samples, so that tests can be performed as they come, with short testing time and high efficiency.

[0015] Preferably, a temporary storage mechanism is further included, wherein the execution end of the temporary storage mechanism is located in the low-temperature furnace body, and the temporary storage mechanism and the sample delivery mechanism can bidirectionally transfer the sample container into the low-temperature furnace body.

[0016] Preferably, the temporary storage mechanism includes a second rotating disk, a second rotating power member and a first translational power member, the second rotating disk is located in the low-temperature furnace body, a plurality of second lofting holes are arranged in the circumference of the second rotating disk, the second lofting holes are connected to the outer circumferential surface of the second rotating disk, the second rotating power member is configured to drive the second rotating disk to rotate around its own center of circle, and the first translational power member is configured to drive the second rotating disk to translate towards or away from the sample feeding mechanism.

[0046] Example 1:

[0047] See Figure 1-Figure 2As shown, the automatic industrial analyzer proposed in this embodiment includes a furnace body 1, a weighing mechanism 3, a transfer mechanism 4, and a sample delivery mechanism 5. The furnace body 1 includes a low-temperature furnace body 11 for sample ashing and a high-temperature furnace body 12 for sample calcination. The temperatures within the low-temperature furnace body 11 and the high-temperature furnace body 12 are independently controlled. For example, the temperature within the low-temperature furnace body 11 is maintained at 500°C or fluctuates within a temperature range from a temperature below 500°C to 500°C, while the temperature within the high-temperature furnace body 12 is controlled at 815°C. The low-temperature furnace body 11 is located above the high-temperature furnace body 12 and is connected to the high-temperature furnace body 12 through a transition channel 11a. A retractable furnace door 111 is provided at the top of the low-temperature furnace body 11. The executing end of the weighing mechanism 3, the executing end of the transfer mechanism 4 and the executing end of the sample delivery mechanism 5 are all arranged in the furnace body 1, among which the sample delivery mechanism 5 is configured to drive the sample container 8 containing the sample to rise and fall in the low-temperature furnace body 11 and the high-temperature furnace body 12, that is, to deliver the sample; the executing end of the weighing mechanism 3 is located in the high-temperature furnace body 12, and is configured to weigh the sample container 8. The executing end of the transfer mechanism 4 is also located in the high-temperature furnace body 12, and is configured to transfer the sample container 8 between the weighing mechanism 3 and the sample delivery mechanism 5. The sample container 8 can stay on the transfer mechanism 4.

[0048] The automatic industrial analyzer is equipped with a low-temperature furnace 11 and a high-temperature furnace 12, which are interconnected. The sample delivery mechanism 5 can drive the sample container 8 to rise and fall within the low-temperature furnace 11 and the high-temperature furnace 12, respectively, so that the sample is ashed in the low-temperature furnace 11 and calcined in the high-temperature furnace 12. When one group of samples (hereinafter referred to as the first sample) is located in the high-temperature furnace 12 and another group of samples whose ash content needs to be measured (hereinafter referred to as the second sample), the sample delivery mechanism 5 can directly deliver the sample container 8 containing the second sample into the low-temperature furnace 11. At this time, the first sample is located in the high-temperature furnace 12 and the second sample is located in the low-temperature furnace 11. The calcination operation of the first sample and the ashing operation of the second sample are performed separately. The measurement of the first sample and the second sample do not interfere with each other, thereby improving the efficiency of ash content measurement. It can be understood that when the sample delivery mechanism 5 removes the sample container 8 containing the second sample, the sample container 8 containing the first sample is located on the transfer mechanism 4 or the weighing mechanism 3, and the sample delivery mechanism 5 is released.

[0049] To form a control group, the same sample group often includes multiple samples. To further improve ash content measurement efficiency, in this embodiment, multiple sample delivery mechanisms 5 can be provided. Correspondingly, the low-temperature furnace body 11 is also provided with multiple furnace doors 111 corresponding to each sample delivery mechanism 5. When the sample container 8 containing the sample is introduced into the furnace body 1, multiple sample delivery mechanisms 5 can operate simultaneously to simultaneously deliver multiple samples from the same sample group into the furnace body 1.

[0050] Optionally, the sample feeding mechanism 5 includes a first lifting power member 52 and a sample feeding rod 51. The first lifting power member 52 is located below the high-temperature furnace body 12 and is connected to the sample feeding rod 51. The top end of the sample feeding rod 51, serving as the actuating end of the sample feeding mechanism 5, penetrates into the high-temperature furnace body 12. Under the action of the first lifting power member 52, the sample feeding rod 51 can perform vertical lifting motion to pass through the transition channel 11a and rise and fall within the low-temperature furnace body 11 and the high-temperature furnace body 12. The first lifting power member 52 is preferably an electric telescopic rod. It will be understood that when there are multiple sample feeding mechanisms 5, the multiple sample feeding mechanisms 5 can share the same first lifting power member 52.

[0051] Optionally, the weighing mechanism 3 includes a weighing rod 31 and a weighing piece 32. The weighing piece 32 is located below the high-temperature furnace body 12. One end of the weighing rod 31 is connected to the weighing piece 32, and the other end is vertically inserted into the high-temperature furnace body 12 as the execution end of the weighing mechanism 3. The weighing piece 32 is configured to weigh the weight change of the sample container 8 (containing the sample). The weighing piece 32 is preferably an electronic balance.

[0052] Optionally, the transfer mechanism 4 includes a first rotating disk 41 and a first rotating power member 43. The first rotating disk 41 is rotatably arranged in the high-temperature furnace body 12 as the execution end of the transfer mechanism 4. It is circumferentially provided with a plurality of first sample holes for placing the sample container 8. The sample feeding rod 51 can pass through the first sample holes. When the sample feeding rod 51 descends, the sample container 8 can be confined in the first sample holes. When the sample feeding rod 51 rises, the sample container 8 can be separated from the first sample holes and continue to rise with the sample feeding rod 51, thereby realizing the transfer of the sample container 8 between the sample feeding rod 51 and the first rotating disk 41. In this embodiment, the sample container 8 is preferably a conical crucible with a larger top and a smaller bottom. The output end of the first rotating power member 43 is connected to the first rotating disk 41 to drive the first rotating disk 41 to rotate around its own center of circle, thereby transferring the sample container 8 to the top of the weighing rod 31. The first rotating power member 43 is preferably a servo motor. It should be emphasized that when one of the first sample placement holes on the first rotating disk 41 is located directly above the weighing rod 31, there must be another first sample placement hole on the first rotating disk 41 located directly above the sample delivery rod 51, and at this time, the sample container 8 is not placed on the first sample placement hole located directly above the sample delivery rod 51, so as to avoid the first rotating disk 41 interfering with the lifting of the sample delivery rod 51 when the weighing mechanism 3 weighs the sample container 8.

[0053] In order to achieve rapid transfer of the sample container 8 between the first rotating disk 41 and the weighing rod 31, the vertical distance between the first rotating disk 41 and the top of the weighing rod 31 is adjustable. Optionally, the transfer mechanism 4 further includes a second lifting power member 42. Under the action of the second lifting power member 42, the first rotating disk 41 can perform a lifting movement. As the first rotating disk 41 descends, the top of the weighing rod 31 lifts the sample container 8, thereby achieving transfer of the sample container 8 between the first rotating disk 41 and the weighing rod 31. As the first rotating disk 41 rises, the sample container 8 detaches from the top of the weighing rod 31 and is lifted by the first rotating disk 41, thereby achieving transfer of the sample container 8 between the weighing rod 31 and the first rotating disk 41.

[0054] In this embodiment, to prevent the temperature changes within the high-temperature furnace body 12 and the low-temperature furnace body 11 from interfering with each other, the transition channel 11a is configured as an elongated cylindrical structure with a cross-sectional area as small as possible. For example, it can be configured to be equal to or slightly larger than the maximum cross-sectional area of ​​the sample container 8. In this case, the transition channel 11a can also reduce the possibility of the sample container 8 tipping over during the lifting and lowering of the sample delivery rod 51, thereby preventing the test sample from spilling out of the sample container 8. In addition, the stability of the sample delivery rod 51 during the lifting and lowering movement of the sample container 8 can be improved by increasing the contact area between the sample delivery rod 51 and the bottom of the sample container 8. Alternatively, a slot can be provided at the bottom of the sample container 8 that matches the shape of the top of the sample delivery rod 51. The sample delivery rod 51 can be inserted into the slot to form a stable connection with the sample container 8.

[0055] In other embodiments, a high-temperature furnace body opening and closing mechanism may be provided between the low-temperature furnace body 11 and the high-temperature furnace body 12. The high-temperature furnace body opening and closing mechanism may specifically adopt a common electric sliding door structure, which will not be described in detail here.

[0056] See Figure 1 and Figure 2 As shown, the volume of the high-temperature furnace body 12 is larger than that of the low-temperature furnace body 11 (there are more functional structures in the high-temperature furnace body 12, including but not limited to the first rotating disk 41). In order to improve the stability of the low-temperature furnace body 11 above the high-temperature furnace body 12, the entire bottom of the low-temperature furnace body 11 is in contact with the top of the high-temperature furnace body 12, and the transition channel 11a is provided in the low-temperature furnace body 11. At this time, the internal space of the low-temperature furnace body 11 includes the low-temperature cavity and the transition channel 11a, and the sample container 8 staying in the low-temperature furnace body 11 mainly refers to the sample container 8 staying in the low-temperature cavity.

[0057] Optionally, in order to facilitate placing the sample container 8 on or removing it from the sample delivery rod 51 without being affected by the temperature of the low-temperature furnace body 11, the furnace door 111 is set at the top of the low-temperature furnace body 11, and the top end of the sample delivery rod 51 can pass through the furnace door 111. At this time, the furnace door 111 can be coaxially arranged with the transition channel 11a, and the outer peripheral contour size of the furnace door 111 is the same as the cross-sectional area of ​​the transition channel 11a, so that the sample container 8 can pass through the transition channel 11a smoothly.

[0058] The temperatures inside the high-temperature furnace body 12 and the low-temperature furnace body 11 are controlled separately. Specifically, electric heating tubes can be wrapped inside / outside the high-temperature furnace body 12 and inside / outside the low-temperature furnace body 11 respectively, and temperature measuring components can be used to monitor the temperatures inside the high-temperature furnace body 12 and the low-temperature furnace body 11 in real time. This will not be explained in detail here.

[0059] The automatic industrial analyzer in this embodiment further includes a controller 7 in communication with the weighing mechanism 3, the transfer mechanism 4, and the sample delivery mechanism 5. The controller 7 is capable of controlling the transfer mechanism 4 and the sample delivery mechanism 5 to perform corresponding operations. For example, when the sample container 8 weighed by the weighing mechanism 3 maintains a constant weight, the controller 7 controls the transfer mechanism 4 to rotate the sample container 8 above the sample delivery rod 51. The controller 7 then controls the first lifting member 52 to rise, causing the sample delivery rod 51 to push the sample container 8 out of the low-temperature furnace 11. The control methods and principles of the controller 7 are conventional and will not be further described in this embodiment.

[0060] Example 2:

[0061] refer to Figure 3 As shown, the automatic industrial analyzer in this embodiment adds a temporary storage mechanism 6 to the first embodiment. The execution end of the temporary storage mechanism 6 is disposed within the low-temperature furnace body 11. The temporary storage mechanism 6 and the sample delivery mechanism 5 can bidirectionally transfer sample containers 8 into the low-temperature furnace body 11. When the number of samples in the same sample group exceeds the number of sample delivery rods 51, the sample containers 8 can be transferred from the sample delivery rods 51 to the temporary storage mechanism 6, and the samples are ashed in the temporary storage mechanism 6. It should be noted that after all samples in the same group are transferred to the temporary storage mechanism 6, the temperature in the low-temperature furnace body 11 is adjusted to a preset temperature, such as 500°C, to prevent changes in the measurement environment between different samples in the same group, which may affect the ashing effect.

[0062] Optionally, the temporary storage mechanism 6 includes a second rotating disk 61 and a second rotating power member 62. The second rotating disk 61 is rotatably arranged in the low-temperature furnace body 11 as the execution end of the temporary storage mechanism 6. The second rotating disk 61 is circumferentially provided with a plurality of second sample holes for placing the sample container 8. The second rotating power member 62 is connected to the second rotating disk 61. Under the action of the second rotating power member 62, the second rotating disk 61 can rotate around its own center. When the sample delivery rod 51 descends and the sample container 8 is stuck in one of the second sample holes on the second rotating disk 61, the second rotating power member 62 can drive the second rotating disk 61 to rotate, thereby moving the sample container 8 away from the sample delivery rod 51, and the sample delivery rod 51 is released. The second rotating power member 62 is preferably a servo motor. Considering the spatial distribution problem, the second rotating power member 62 is arranged above the low-temperature furnace body 11, and its output end penetrates into the low-temperature furnace body 11 and is connected to the second rotating disk 61.

[0063] In order to prevent the second rotating disk 61 from interfering with the process of transferring the sample container 8 from the low-temperature furnace body 11 to the high-temperature furnace body 12, the temporary storage mechanism 6 also includes a first translational force member 63 located above the low-temperature furnace body 11. The first translational force member 63 is connected to the second rotational power member 62 to drive the second rotational power member 62 and the second rotating disk 61 to perform translational movement toward or away from the sample delivery rod 51. It should be emphasized that based on the configuration of the above-mentioned first translational force member 63, the second sample placement hole on the second rotating disk 61 is connected to the outer peripheral surface of the second rotating disk 61, so that the sample delivery rod 51 can enter or leave the second sample placement hole during the translation of the second rotating disk 61.

[0064] It should be noted that the hole in the low-temperature furnace body 11 for inserting the second rotating power member 62 is a waist-shaped hole extending along the translational direction of the second rotating disk 61 to provide clearance for the movement of the second rotating power member 62. A high-temperature-resistant flexible sealing gasket with a slit can be installed in the waist-shaped hole to minimize connectivity between the low-temperature furnace body 11 and the outside air, thereby reducing heat loss within the low-temperature furnace body 11.

[0065] Based on the premise that the samples can be ashed at a constant temperature, the sample delivery rod 51 can also perform the sample delivery operation of another group of samples while one group of samples is ashed, that is, different groups of samples are ashed in the low-temperature furnace body 11 at the same time, which improves the test efficiency.

[0066] Example 3:

[0067] See Figure 4The automatic industrial analyzer shown in the figure adds a translation function of the transfer mechanism 4 on the basis of the second embodiment to avoid interference between the rotation movement of the first rotating disk 41 and the rising movement of the sample delivery rod 51. Specifically, the transfer mechanism 4 also includes a second translation force member 44, and the first rotating power member 43 is arranged at the output end of the second translation force member 44, and the second translation force member 44 is located below the high-temperature furnace body 12. Under the action of the second translation force member 44, the first rotating power member 43 and the first rotating disk 41 can perform translational movement close to or away from the sample delivery rod 51. At this time, the first sample hole on the first rotating disk 41 is also connected to the outer peripheral surface of the first rotating disk 41. The principle is the same as the way the sample delivery rod 51 enters or leaves the second sample hole, and will not be repeated.

[0068] The holes in the high-temperature furnace body 12 for inserting the output ends of the first rotating power member 43 and / or the second lifting power member 42 are waist-shaped holes extending along the translational direction of the first rotating disk 41. High-temperature-resistant flexible sealing gaskets with slits are installed in the waist-shaped holes to minimize communication between the high-temperature furnace body 12 and the outside air, thereby reducing heat loss within the high-temperature furnace body 12.

[0069] It is understandable that in other embodiments, the translation function of the transfer mechanism 4 can be added on the basis of the first embodiment, that is, the translation function of the transfer mechanism 4 can be added on the basis of not setting the temporary storage mechanism 6, which will not be described in detail here.

[0070] Example 4:

[0071] Based on the automatic industrial analyzer in Example 1, this embodiment also includes a control method for the automatic industrial analyzer, which is used to complete the detection of the sample. The control method mainly includes the following steps:

[0072] S1. When there is a sample to be tested, the furnace door 111 is opened, and the execution end of the sample feeding mechanism 5 rises to the outside of the furnace door 111. Specifically, the top end of the sample feeding rod 51 rises to the outside of the furnace door 111 under the action of the first lifting power member 52.

[0073] S2. Place the sample container 8 containing the sample on the sample delivery rod 51 of the sample delivery mechanism 5.

[0074] S3. The sample delivery rod 51 is lowered into the low-temperature furnace body 11 under the action of the first lifting power member 52 so that the sample container 8 remains in the low-temperature furnace body 11 for a first preset time. The first preset time can be adaptively adjusted according to different samples. Different samples correspond to different first preset times. For example, the first preset time is set to 30 minutes.

[0075] It should be noted that after the sample container 8 completely enters the low-temperature furnace body 11 , the furnace door 111 needs to be closed to reduce heat loss in the low-temperature furnace body 11 .

[0076] S4: The sample delivery rod 51 descends, allowing the sample container 8 to enter the high-temperature furnace 12. It then descends below the first rotating disk 41, where it is transferred to the first rotating disk 41 of the transfer mechanism 4. After the sample container 8 remains within the high-temperature furnace 12 for a second preset time (e.g., 60 minutes), the sample container 8 is weighed using the weighing member 32 at intervals of a third preset time (e.g., 10 minutes). During this process, the sample container 8 is transferred between the transfer mechanism 4 and the weighing rod 31 by the following operations: the first rotating disk 41 rotates to transfer the sample container 8 to the top of the weighing rod 31 of the weighing mechanism 3. The weighing rod 31 lifts the sample container 8. After weighing is completed, the weighing rod 31 descends, allowing the sample container 8 to return to the first sample placement hole. If multiple sample containers 8 containing samples are placed on the first rotating disk 41, different sample containers 8 can be weighed by rotating the first rotating disk 41. While the weighing rod 31 is released, another sample delivery operation can be performed.

[0077] S5. When the sample container 8 maintains a constant weight on the weighing piece 32, the weighing piece 32 transfers the sample container 8 to the first rotating disk 41. The first rotating disk 41 rotates so that the sample container 8 is located above the sample delivery rod 51. The sample delivery rod 51 lifts the sample container 8 and sends the sample container 8 out of the furnace door 111, completing the sample test.

[0078] Embodiment 5:

[0079] Based on the automatic industrial analyzers described in Examples 2 and 3, this embodiment provides a control method for an automatic industrial analyzer for testing samples. This method is primarily applicable when one set of samples is located within a low-temperature furnace 11 while another set of samples is being tested. Steps S1-S2 and S4-S5 of the control method in this embodiment are identical to those in Example 4; the main difference lies in step S3.

[0080] S3: The sample delivery rod 51, under the action of the first lifting force member 52, transfers the sample container 8 into the low-temperature furnace body 11. It then continues to descend, causing the sample container 8 to be stuck in one of the second sample placement holes of the second rotating disk 61. The second rotating disk 61 rotates, causing the sample container 8 to move away from the sample delivery rod 51, and the sample delivery rod 51 is released. After the sample container 8 remains in the low-temperature furnace body 11 for a first preset time, the second rotating disk 61 positions the sample container 8 corresponding to the position of the sample delivery rod 51. The sample delivery rod 51 lifts the sample container 8, and the second rotating disk 61, under the action of the first translation force member 63, performs a translational motion away from the sample delivery rod 51, causing the sample container 8 to disengage from the second rotating disk 61. While the sample delivery rod 51 is released, another sample delivery operation can be performed.

[0081] It should be emphasized that in Example 3, since the first rotating disk 41 can make a translational motion close to or away from the sample delivery rod 51, the rotation of the first rotating disk 41 does not interfere with the lifting and lowering of the sample delivery rod 51. Compared with Example 2, the control method based on industrial analysis of Example 3 has higher test efficiency.

[0082] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
