[0049] As Figure 3 shown, the furnace assembly 200 includes a furnace 210 and a combustion unit 220, the inside of the furnace 210 is provided with a circular hole, the axial direction of the circular hole is configured as the Z-axis direction, and the combustion unit 220 is installed in the circular hole. The combustion unit 220 includes a heating tube 221 and a combustion tube 222, the heating tube 221 is coaxially arranged in the circular hole, and the combustion tube 222 is coaxially arranged on the inside of the heating tube 221. The heating tube 221 can generate heat and transfer the heat to the combustion tube 222, so that the sample in the combustion tube 222 is burned. In the embodiment, the heating tube 221 is configured as a silicon-carbon tube, the axial direction of the combustion tube 222 is configured as the Z-axis direction, the lower end of the combustion tube 222 is configured as a sample inlet, the sample container 600 enters the combustion tube 222 from the sample inlet, and the upper end of the combustion tube 222 is in communication with the sulfur measuring assembly 300.

[0050] In some preferred embodiments, the number of combustion units 220 is two, and the two combustion units 220 are symmetrically arranged in the furnace 210 about the Z-axis direction. In the embodiment, two combustion units 220 are arranged, two samples can be burned at the same time, and the measurement efficiency is improved.

[0051] As Figure 3As shown in the drawings, in some preferred embodiments, the combustion unit 220 further comprises a temperature measuring probe 223, which is arranged on the hearth 210 and extends into the circular hole of the hearth 210, and through which the temperature of the combustion tube 222 is detected and controlled to ensure the accurate measurement.

[0052] As shown in the drawings, Figure 4 In some preferred embodiments, the hearth 210 is vertically arranged on the workbench 100, and the cross-sectional shape of the hearth 210 in the X-axis direction or the Y-axis direction is configured as an ellipse, that is, the cross-sectional shape of the hearth 210 is elliptical, and the two combustion units 220 are arranged along the long axis direction of the ellipse. In this embodiment, the shape of the hearth 210 is designed as an ellipse, so that the hearth 210 has a larger arrangement space inside, and the two combustion units 220 can be arranged along the long axis direction without interfering with each other.

[0053] The sulfur measuring assembly 300 is used to collect the gas generated by the sample combustion and measure the sulfur content. The structure and principle of the sulfur measuring assembly 300 of the present embodiment can refer to the prior art. In order to fully illustrate the present scheme, the structure and principle of the sulfur measuring assembly 300 are briefly described below.

[0054] As shown in the drawings, Figure 5 The sulfur measuring assembly 300 comprises an electrolytic cell 310, a drying tube 320 and a vacuum pump 330, which are sequentially communicated through pipelines. The electrolytic cell 310 is communicated with the upper end of the combustion tube 222 through a pipeline. The vacuum pump 330 sucks the gas (sulfide gas) generated after the sample is burned into the electrolytic cell 310 for measurement, and the tail gas after measurement is discharged from the vacuum pump 330 after passing through the drying tube 320.

[0055] The specific principle is as follows:

[0056] The sample (coal sample) reacts with oxygen in the air under the action of high temperature (usually 1150°C) and catalyst to generate sulfur dioxide (SO2), which converts the sulfur element in coal, petroleum or other sulfur-containing substances into a detectable gaseous form.

[0057] The generated sulfur dioxide enters the electrolytic cell 310, and the reaction of the electrolytic cell 310 is as follows: sulfur dioxide and triiodide ions in the electrolyte undergo a redox reaction (I3 - + SO2 + H2O → SO3 + 3I - + 2H + ), which causes the potential of the electrolyte to change;

[0058] Electricity calculation: the consumed electricity is calculated according to Faraday's law by integrating the current and time (Coulomb integration) through the electrolytic cell 310, and the consumed electricity directly reflects the content of sulfur in the sample.

[0059] In the embodiment, since two combustion units 220 are arranged in the furnace 210, two sulfur measuring assemblies 300 are also arranged in the embodiment, and each of the sulfur measuring assemblies 300 is in communication with one of the combustion units 220.

[0060] As shown in Figure 6 , the rotating assembly 400 is used for rotating and conveying the sample and the sample container 600. The rotating assembly 400 comprises a driving unit 410 and a rotating tray 420. The rotating tray 420 is horizontally arranged, is located below the furnace 210, is located on one horizontal side of the furnace 210, and can rotate around the Z-axis direction. The driving unit 410 is connected with the rotating tray 420 and can drive the rotating tray 420 to rotate around the Z-axis direction.

[0061] As shown in Figure 6 and Figure 7 , in the embodiment, the rotating tray 420 is disc-shaped, and a plurality of mounting holes 420a are arranged at the edge position of the rotating tray 420 and are equidistantly arranged along the circumferential direction of the rotating tray 420. The sample container 600 can be arranged in the mounting hole 420a along the Z-axis direction, and the sample container 600 is supported by the stepped surface in the mounting hole 420a to avoid falling downward.

[0062] In the embodiment, the rotating tray 420 is arranged to realize the rotating and conveying of the sample container 600, which can improve the work efficiency and reduce the disorder of the on-site sample stacking.

[0063] As shown in Figure 6 , the driving unit 410 comprises a first rotating driving member 413. The output end of the first rotating driving member 413 can be connected with the rotating tray 420, so as to drive the rotating tray 420 to rotate around the Z-axis direction.

[0064] As shown in Figure 6 , preferably in the embodiment, the driving unit 410 comprises a lifting frame 411, a telescopic driving member 412, and the first rotating driving member 413. The lifting frame 411 is slidingly arranged in the workbench 100 along the Z-axis direction, is located directly below the rotating tray 420, the telescopic driving member 412 is configured as a telescopic cylinder or an electric push rod, is arranged in the workbench 100, and the output end of the telescopic driving member 412 is connected with the lifting frame 411. The lifting frame 411 and the rotating tray 420 are driven to move in the Z-axis direction by the telescopic driving member 412. The rotating tray 420 is rotationally connected with the lifting frame 411, the first rotating driving member 413 is arranged on the lifting frame 411, and the output end of the first rotating driving member 413 is connected with the rotating tray 420. Thus, the rotating tray 420 can be driven to rotate around the Z-axis direction by the first rotating driving member 413.

[0065] As Figure 8 shown, in the preferred embodiment, a weighing unit 430 is arranged on one side of the lifting frame 411 in the X-axis direction or the Y-axis direction, which can be used for automatic weighing of the sample. The weighing unit 430 includes a weighing balance 431 and a weighing rod 432. The weighing balance 431 is arranged on one side of the lifting frame 411, and the weighing rod 432 is arranged vertically and located below the rotary tray 420. The lower end of the weighing rod 432 is arranged on the weighing balance 431, and the upper end of the weighing rod 432 corresponds to the edge position of the rotary tray 420. In the preferred embodiment, the upper end of the weighing rod 432 corresponds to the mounting hole 420a of the rotary tray 420 in the Z-axis direction.

[0066] As Figure 8 shown, the working principle of the weighing unit 430 is as follows: the rotary tray 420 is rotated so that a certain sample container 600 on the rotary tray 420 corresponds to the weighing rod 432 in the Z-axis direction. Then the extension drive 412 of the driving unit 410 drives the rotary tray 420 to move downward, so that the weighing rod 432 penetrates into the mounting hole 420a of the rotary tray 420 and lifts the sample container 600 on the rotary tray 420 upward to realize weighing. The weighing balance 431 records the weight of the sample. After the current sample is weighed, the rotary tray 420 rises, and the sample container 600 falls into the mounting hole 420a again. When the next sample needs to be weighed, the rotary tray 420 is rotated by a certain angle so that the next mounting hole 420a on the rotary tray 420 is aligned with the weighing rod 432, and then it can be lowered again.

[0067] The weighing unit 430 of the preferred embodiment can realize automatic weighing through the downward movement of the rotary tray 420, which can reduce the error probability and improve the work efficiency.

[0068] As Figure 9 shown, the sample feeding assembly 500 includes a Z-axis linear module 510 and a swing sampling unit 520. The Z-axis linear module 510 is used to drive the swing sampling unit 520 to move in the Z-axis direction. The swing sampling unit 520 is used to transfer the sample container 600 on the rotary tray 420 to the position directly below the combustion tube 222, and then the Z-axis linear module 510 is used to feed the sample container 600 upward into the combustion tube 222 for burning test.

[0069] As Figure 9As shown, in the embodiment, the Z-axis linear module 510 includes a linear module 511 and a moving block 512, the linear module 511 is arranged below the combustion tube 222, the specific structure of the linear module 511 can refer to the prior art, and the main function thereof is to drive the moving block 512 to move linearly in the Z-axis direction, and therefore it can be understood that the execution component capable of achieving linear driving in the prior art can be used as the linear module 511 of the embodiment. The moving block 512 is connected to the linear module 511, and the moving block 512 can move up and down in the Z-axis direction.

[0071] As shown in the figure, Figure 10 As shown in the figure, in the embodiment, the sample feeding rod 522 has two position states, which are a first position and a second position, Figure 10 The dashed line in the figure indicates the state of the sample feeding rod 522 in the first position, and the arrow F indicates the swing direction of the sample feeding rod 522 from the second position to the first position, wherein the second rotary driving member 523 can drive the swing block 521 to swing, and then drive the sample feeding rod 522 to swing from the first position to the second position, or drive the sample feeding rod 522 to swing from the second position to the first position, wherein the first position corresponds to the Z-axis direction of the combustion tube 222, that is, when the sample feeding rod 522 is in the first position, the sample feeding rod 522 is coaxially corresponding to one combustion tube 222 in the Z-axis direction, and the second position corresponds to the Z-axis direction of the mounting hole 420a, that is, when the sample feeding rod 522 is in the second position, the sample feeding rod 522 is coaxially corresponding to a certain mounting hole 420a on the rotary tray 420 in the Z-axis direction.

[0072] As shown in the figure, Figure 11As shown, the sample feeding process of the sample feeding assembly 500 is as follows: the rotary tray 420 rotates by a certain angle, and then the sample feeding rod 522 swings to the second position, at which time the sample feeding rod 522 is coaxial with the mounting hole 420a on the rotary tray 420, the Z-axis linear module 510 drives the swing block 521 and the sample feeding rod 522 to move upward, the upper end of the sample feeding rod 522 penetrates into the corresponding mounting hole 420a and lifts the sample container 600 in the mounting hole 420a upward, and the sample container 600 is then separated from the rotary tray 420, and then the sample feeding rod 522 swings from the second position to the first position, and the sample container 600 swings to the first position with the sample feeding rod 522, at which time the combustion tube 222, the sample container 600 and the sample feeding rod 522 are coaxial in the Z-axis direction, and the Z-axis linear module 510 drives the sample feeding rod 522 and the sample container 600 to move upward, and the sample container 600 is fed into the combustion tube 222.

Of course, these are only some adaptive designs, and the workbench 100 can directly adopt a large area of hollow part to solve the interference problem between the workbench 100 and the sample feeding rod 522, for example, a large hollow hole is arranged at the position corresponding to the sample feeding assembly 500 in the Z-axis direction, and the hollow hole can allow the sample feeding rod 522 to swing freely in the horizontal direction without interfering with the workbench 100.

[0075] Please refer again to Figure 9In the embodiment, preferably, two combustion units 220 are symmetrically arranged in the furnace 210, and each of the two combustion units 220 comprises a heating pipe 221 and a combustion pipe 222. Therefore, in order to synchronously feed samples into the two combustion units 220, two swing sampling units 520 are arranged in the embodiment, and the two swing sampling units 520 are symmetrically arranged on the moving block 512 with respect to the Z-axis direction.

[0076] As shown in Figure 10 , when the sample feeding rods 522 of the two swing sampling units 520 are in the first position, the sample feeding rods 522 of the two swing sampling units 520 correspond to the combustion pipes 222 of the two combustion units 220 one by one in the Z-axis direction, and when the sample feeding rods 522 of the two swing sampling units 520 are in the second position, the sample feeding rods 522 of the two swing sampling units 520 correspond to the adjacent two mounting holes 420a one by one in the Z-axis direction.

[0077] In the embodiment, the two swing sampling units 520 are designed to synchronously feed samples into the two combustion pipes 222, which greatly improves the work efficiency.

[0078] In the embodiment, preferably, each of the two combustion units 220 in the furnace 210 is provided with one combustion pipe 222, and the center distance of the two combustion pipes 222 in the horizontal direction is configured as D1, as shown in Figure 3 . The rotating disc 420 is provided with a plurality of mounting holes 420a, and the center distance of the adjacent two mounting holes 420a is configured as D2, as shown in Figure 11 .

[0079] As shown in Figure 10 , each of the two swing sampling units 520 is provided with one sample feeding rod 522, the center distance between the two sample feeding rods 522 when the two sample feeding rods 522 are in the first position is configured as L1, and the center distance between the two sample feeding rods 522 when the two sample feeding rods 522 are in the second position is configured as L2.

[0080] Wherein, L1 is equal to D1, which can ensure that the distance between the two sample rods 522 in the first position is equal to the distance between the two combustion pipes 222, so as to facilitate the one-to-one correspondence of the two sample rods 522 to send the sample into the combustion pipe 222. L2 is equal to D2, which can ensure that the distance between the two sample rods 522 in the second position is equal to the distance between the two mounting holes 420a, so as to facilitate the one-to-one correspondence of the two sample rods 522 to be inserted into the mounting hole 420a and to lift the sample container 600 in the mounting hole 420a. D1 is greater than D2, and D1 is the larger one compared with D2, which can ensure that the two combustion pipes 222 in the furnace 210 maintain a certain distance and avoid mutual influence. At the same time, D2 takes a smaller value, and the distance between the two mounting holes 420a is as small as possible, so that more mounting holes 420a can be designed in a limited position, and more sample containers 600 can be assembled.

[0081] The working principle of the sulfur measuring device of the embodiment is as follows:

[0082] I. Put the sample into the sample container 600, and the sample container 600 is placed one-to-one in the mounting hole 420a of the rotary tray 420;

[0083] II. The rotary tray 420 rotates around the Z-axis direction by a certain angle and stops;

[0084] III. The second rotary drive member 523 drives the sample rod 522 to swing from the first position to the second position, at this time the sample rod 522 is aligned with the mounting hole 420a in the Z-axis direction, and the Z-axis linear module 510 drives the sample rod 522 to lift the sample container 600 in the mounting hole 420a;

[0085] IV. The second rotary drive member 523 drives the sample rod 522 to swing from the second position to the first position, at this time the sample rod 522 is aligned with the combustion pipe 222 in the Z-axis direction, and the Z-axis linear module 510 drives the sample rod 522 to send the sample container 600 into the combustion pipe 222, and the heating pipe 221 heats the inside of the combustion pipe 222 to make the sample be burned and produce gas;

[0086] V. The sulfur measuring assembly 300 collects the gas and measures the sulfur content, after the measurement is completed, the Z-axis linear module 510 drives the sample rod 522 to move downward, and the sample container 600 is taken out of the combustion pipe 222, and then swings from the first position to the second position, and then downwardly puts the sample container 600 back into the mounting hole 420a of the rotary tray 420.

[0087] Embodiment two:

[0088] As Figure 12 and Figure 13As shown, the difference between the second embodiment and the first embodiment is that the sulfur measuring device of the second embodiment further includes an auxiliary material adding component 700; the auxiliary material adding component 700 is arranged on the workbench 100, and is used to add auxiliary materials into the sample container 600 on the rotating material disk 420. The auxiliary materials can be some chemical substances, such as tungsten trioxide.

The auxiliary material cannot fall downward from the closed area 711, but the auxiliary material can fall downward from the blanking outlet area 712 into the sample container 600, wherein the inner bottom surface of the accommodating cavity of the second embodiment is arranged corresponding to the mounting hole 420a of the rotating material tray 420 in the Z-axis direction.

In the second embodiment, a cross bar 713 is provided in the middle of the accommodating cavity, and the upper end of the rotary blanking rod 720 passes through the cross bar 713 upward so that the rotary blanking rod 720 can rotate around the Z-axis direction.

A blanking trough 720a is provided on the circular baffle 721, which is connected along the Z-axis direction. The shape and specifications of the blanking trough 720a are smaller than or equal to the closed area 711. When the blanking trough 720a corresponds to the closed area 711 in the Z-axis direction, the closed area 711 can block the blanking trough 720a, so that the auxiliary material in the accommodating chamber cannot fall downward through the blanking trough 720a to the bottom of the auxiliary material barrel 710. When the circular baffle 721 rotates around the Z-axis direction, so that the blanking trough 720a corresponds to the blanking outlet area 712 in the Z-axis direction, the material in the accommodating chamber can fall downward through the blanking trough 720a and the blanking outlet area 712, and finally fall into the sample container 600.

[0091] like Figure 14 As shown, in some preferred embodiments, the material outlet area 712 is provided with a plurality of material dropping holes in an array, so that the auxiliary material in the auxiliary material cylinder 710 can be evenly sprinkled into the sample container 600 through the material dropping holes.

[0092] like Figure 15 and Figure 16As shown, the elastic member 730 is coaxially sleeved on the outer periphery of the rotating material dropping rod 720, the extension direction of the elastic member 730 is configured as the Z-axis direction, the elastic member 730 can press the rotating material dropping rod 720 downward on the inner bottom surface of the accommodating cavity, and leakage of the auxiliary material is avoided. In the second embodiment, the elastic member 730 is preferably a spring, the spring is coaxially sleeved on the outer periphery of the rotating material dropping rod 720, the upper end of the spring abuts against the cross rod 713, and the lower end of the spring abuts against the shaft shoulder of the rotating material dropping rod 720, and the spring presses the circular baffle 721 of the rotating material dropping rod 720 on the inner bottom surface of the accommodating cavity.

[0093] As shown in the figure, Figure 15 The third rotating driving member 740 is arranged at the upper end of the auxiliary material cylinder 710, the output end of the third rotating driving member 740 extends downward and is coaxially connected with the upper end of the rotating material dropping rod 720, the rotating material dropping rod 720 is driven to rotate around the Z-axis direction by the third rotating driving member 740, so that the material dropping groove 720a can be switched to correspond to the closed area 711 or the material dropping outlet area 712. In the embodiment, the first rotating driving member 413, the second rotating driving member 523 and the third rotating driving member 740 are all preferably motors.

[0094] The working principle of the auxiliary material adding assembly 700 in the second embodiment is as follows:

[0095] The rotating disc 420 rotates by a certain angle around the Z-axis direction and stops, the third rotating driving member 740 of the auxiliary material adding assembly 700 drives the rotating material dropping rod 720 to rotate, so that the material dropping groove 720a corresponds to the material dropping outlet area 712 in the Z-axis direction, the auxiliary material in the accommodating cavity falls into the sample container 600 through the material dropping groove 720a and the material dropping outlet area 712, after the falling amount reaches the set standard, the third rotating driving member 740 drives the rotating material dropping rod 720 to rotate, so that the material dropping groove 720a corresponds to the closed area 711 in the Z-axis direction, and the closed area 711 blocks the material dropping groove 720a, and the auxiliary material adding work for the current sample container 600 is completed.
