All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0021] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic structural diagram of a rotary kiln experimental device provided in an embodiment of the present application. Figure 2 yes Figure 1 The front view of the rotary kiln experimental device is shown. Figure 3 yes Figure 1 The rotary kiln experimental device may include: a housing 100 , a furnace tube 200 , a transmission shaft 300 and a driving component 400 .

[0022] The housing 100 of the rotary kiln experimental device may include an upper shell 101 and a lower shell 102 that are arranged opposite each other and movably connected. The upper shell 101 and the lower shell 102 may enclose a receiving cavity Q1. A side surface of the housing 100 includes an opening Q2 that communicates with the receiving cavity Q. For example, one end of the upper shell 101 may be rotatably connected to one end of the lower shell 102 via a hinge.

[0023] The furnace tube 200 in the rotary furnace experimental device can be located in the accommodating cavity Q1.

[0024] The transmission shaft 300 in the rotary kiln experimental device may include: a first rotating shaft 301 and a second rotating shaft 302 arranged coaxially, wherein the first rotating shaft 301 is fixedly connected to the furnace tube 200. A portion of the first rotating shaft 301 may be located inside the furnace tube 200 and parallel to the axial direction of the furnace tube 200, and another portion of the first rotating shaft 301 may pass through the opening Q2 and be located outside the accommodating cavity Q1 of the shell 100 and be detachably connected to the second rotating shaft 302. The driving component 400 may be in transmission connection with the second rotating shaft 302. For example, the side surface of the first rotating shaft 301 may have a plurality of connecting rods for fixed connection with the end of the furnace tube 200, and the plurality of connecting rods may be distributed around the first rotating shaft 301. In other possible implementation arrangements, the first rotating shaft 301 and the furnace tube 200 may be an integral structure.

[0025] The driving component 400 may be configured to: drive the second rotating shaft 302 to rotate while driving the furnace tube 200 to rotate synchronously via the first rotating shaft 301 .

[0026] In the embodiment of the present application, the furnace tube 200 in the rotary kiln experimental device is fixed on one side, so that the first rotating shaft 301 fixed to the furnace tube 200 and the second rotating shaft 302 connected to the driving component 400 are detachably connected. Thus, when removing and replacing the furnace tube 200, the upper shell 101 is separated from the lower shell 102, and the two rotating shafts are separated at the connection between the first rotating shaft 301 and the second rotating shaft 302, and the furnace tube 200 can be removed. This effectively simplifies the replacement operation of the furnace tube 200 in the rotary kiln experimental device, improves the efficiency of furnace tube replacement, and reduces labor costs. After the furnace tube is replaced with another furnace tube, the two rotating shafts are assembled and connected, and the upper shell 101 and the lower shell 102 are restored to their connection.

[0027] In summary, the rotary kiln experimental device provided in the embodiment of the present application may include: a housing, a furnace tube, a transmission shaft, and a drive component. The furnace tube in the rotary kiln experimental device is fixed on one side, that is, the first rotating shaft fixed to the furnace tube and the second rotating shaft connected to the drive component are detachably connected. In this way, when disassembling and replacing the furnace tube, the upper shell is separated from the lower shell, and the two rotating shafts are separated at the connection between the first rotating shaft and the second rotating shaft, so that the furnace tube can be removed. This effectively simplifies the replacement operation of the furnace tube in the rotary kiln experimental device, improves the efficiency of furnace tube replacement, and reduces labor costs. After the furnace tube is replaced with another furnace tube, the two rotating shafts are connected to restore the connection between the upper shell and the lower shell.

[0028] Optional, please refer to Figure 4 , Figure 4It is a cross-sectional view of another rotary kiln experimental device provided in an embodiment of the present application. The end of the first rotating shaft 301 close to the second rotating shaft 302 may have a first connecting flange 301a, and the end of the second rotating shaft 302 close to the first rotating shaft 301 may have a second connecting flange 302a. The first connecting flange 301a and the second connecting flange 302a are connected by a plurality of bolts. In this way, the first rotating shaft 301 and the second rotating shaft 302 are detachably connected by two connecting flanges and a plurality of bolts, thereby ensuring the convenience of assembling and disassembling the two rotating shafts. It should be noted that the first rotating shaft 301 and the second rotating shaft 302 can also be detachably connected in other ways. For example, the end of one of the first rotating shaft 301 and the second rotating shaft 302 has an axial hole, and the other of the first rotating shaft 301 and the second rotating shaft 302 can be keyed to the axial hole.

[0029] In an embodiment of the present application, the housing 100 may have a first heat-resistant member (not shown in the figure) fixed to the inner wall of the opening Q2 and sleeved on the first rotating shaft 301, and / or, the housing 100 may have a second heat-resistant member (not shown in the figure) fixed to the inner wall of the accommodating cavity Q1 and sleeved on the first rotating shaft 301 to cover the gap between the first rotating shaft 301 and the opening Q2. For example, in the first case, the shell 100 may have a first heat-resistant member fixed on the inner wall of the opening Q2 and sleeved on the first rotating shaft 301; in the second case, the shell 100 may have a second heat-resistant member fixed on the inner wall of the accommodating cavity Q1 and sleeved on the first rotating shaft 301 to cover the gap between the first rotating shaft 301 and the opening Q2; in the third case, the shell 100 may have a first heat-resistant member fixed on the inner wall of the opening Q2 and sleeved on the first rotating shaft 301, and the shell may have a second heat-resistant member fixed on the inner wall of the accommodating cavity Q1 and sleeved on the first rotating shaft 301 to cover the gap between the first rotating shaft 301 and the opening Q2.

[0030] In this way, by setting a first heat resistance member on the inner wall of the opening Q2 and / or setting a second heat resistance member on the inner wall of the accommodating cavity Q1, heat loss in the furnace tube 200 can be effectively prevented, ensuring sufficient reaction of the material in the furnace tube 200.

[0031] Optional, such as Figure 4As shown, the rotary kiln experimental device may further include: an insulation layer 500 fixed to the inner wall of the accommodating cavity Q1 of the housing 100 and arranged around the furnace tube 200, and an electric heating component 600 fixed to the side of the insulation layer 500 close to the furnace tube 200. In this way, the furnace tube 200 can be heated and heated by the electric heating component 600 to reach the reaction temperature required by the material. In addition, the insulation layer 500 can protect the furnace temperature inside the furnace tube 200 and prevent the undesirable phenomenon of the furnace temperature dropping rapidly after the furnace tube 200 is heated. For example, the electric heating component 600 may include multiple coils of electric heating wire fixed to the insulation layer 500. The power of the electric heating wire can be controlled by the control console in the rotary kiln experimental device to arbitrarily adjust the heating temperature of the furnace tube 200.

[0032] In the embodiments of this application, Figure 4 As shown, the portion of the first rotating shaft 301 located within the furnace tube 200 includes a first branch pipe 301b and a second branch pipe 301c. Both the first branch pipe 301b and the second branch pipe 301c can be arranged perpendicular to the axial direction of the first rotating shaft 301. The rotary furnace experimental device can further include a wall temperature measurement module 700, a material temperature measurement module 800, and a control console (not shown). The wall temperature measurement module 700 can be mounted at the end of the first branch pipe 301b, and the material temperature measurement module 800 can be mounted at the end of the second branch pipe 301c. The control console can be communicatively connected to the wall temperature measurement module 700 and receive temperature signals of the inner wall of the furnace tube 200 detected by the wall temperature measurement module 700. The control console can also be communicatively connected to the material temperature measurement module 800 and receive temperature signals of the material within the furnace tube 200 detected by the material temperature measurement module 800.

[0033] It should be noted that temperature measurements are taken of both the inner wall of the furnace tube 200 and the material within the tube 200, and the collected data is qualitatively analyzed. The wall temperature measurement module 700 is installed in the first branch tube 301b, and the material temperature measurement module 800 is installed in the second branch tube 301c. The length of the first branch tube 301b is greater than that of the second branch tube 301c, ensuring the accuracy of the wall temperature measurement module 700's temperature measurement of the inner wall of the furnace tube 200. Furthermore, due to gravity, the material within the furnace tube 200 remains substantially at the bottom of the tube 200 during its rotation. Therefore, the data measured by the material temperature measurement module 800 can be used to analyze temperature changes in the material.

[0034] For example, the console may include: a control component and a display screen, and the control component may be respectively connected to the display screen and the wall temperature measurement module and the material temperature measurement module. For example, the control component may include a PLC control system and a wireless communication module, and the temperature signal collected by the temperature measurement module may be sent to the PLC control system without the need for a communication module, and the display screen may be connected to the PLC control system through a signal converter. It should be noted that the wall temperature measurement module 700 and the material temperature measurement module 800 may also be externally connected by means of signal lines, and the first rotating shaft 301 and the second rotating shaft 302 may both be hollow shafts, and the first rotating shaft 301 may be connected to the first branch pipe 301b and the second branch pipe 301c, so that the signal line can transmit the temperature signal detected by the temperature measurement module. Here, the wall temperature measurement module 700 and the material temperature measurement module 800 may both be temperature detection sensors.

[0035] In this application, if Figure 4 As shown, the upper shell 101 may also have a first mounting hole a1, and the insulation layer 500 may have a second mounting hole a2 connected to the first mounting hole a1. The rotary kiln experimental device may also include: an auxiliary temperature measurement module 900 installed in the first mounting hole a1 and the second mounting hole a2. The console can be electrically connected to the auxiliary temperature measurement module 900 and receive the temperature signal of the electric heating component 600 detected by the auxiliary temperature measurement module 900. In this way, the temperature of the electric heating component 600 can be detected in real time through the auxiliary temperature measurement module 900 to achieve precise adjustment of the heating temperature of the electric heating component 600. Here, the auxiliary temperature measurement module 900 can be a temperature detection sensor.

[0036] Optional, such as Figure 4 and Figure 5 As shown, Figure 5 Schematic diagram of the structure of another rotary kiln experimental device provided in an embodiment of the present application. A feed port Q3 may be provided on the side of the housing 100 facing away from the opening Q2. The rotary kiln experimental device may further include a clamp ring 1000 and a transparent window 1100. The clamp ring 1000 may be fixed to the edge of the feed port Q3 on the outside of the housing 100, and the transparent window 1100 may be installed within the clamp ring 1000 and cover the feed port Q3. Thus, by providing the transparent window 1100 at the feed port Q3, the movement trajectory and reaction state of the material within the furnace tube 200 can be observed in real time. When loading material into the furnace tube 200, the transparent window 1100 is easily removed from the clamp ring 1000, and the height of the loaded material needs to be lower than the height of the annular baffles at both ends of the furnace tube 200. For example, the transparent window 1100 may be a plate-like structure made of high-temperature resistant quartz glass.

[0037] In the embodiments of this application, Figure 5As shown, the rotary kiln experimental device may further include a support 1200, and a first support beam 1300 and a second support beam 1400 fixed to the support 1200. The first support beam 1300 may be connected to the lower shell 102, and the second support beam 1400 may be rotatably connected to the second rotating shaft 302. Thus, the support 1200 and the two support beams provide stable support for the housing 100 and the driving component 400.

[0038] For example, Figure 4 and Figure 5 As shown, the top of the second support beam 1400 can be connected to the sleeve 1401, and the inner wall of the connecting sleeve 1401 is fixed with a graphite sleeve 1402. The end of the second rotating shaft 302 can be located in the graphite sleeve 1402 and rotatably connected to the graphite sleeve 1402.

[0039] Optional, such as Figure 5 As shown, two adjacent corners of the support 1200 may have universal wheels 1201, and the other two adjacent corners may have adjustment wheels 1202 threadedly connected to the support 1200. Thus, the cooperation between the universal wheels 1201 and the adjustment wheels 1202 facilitates the transfer of the rotary kiln experimental device. Furthermore, the adjustment wheels 1202 may be threadedly connected to the support 1200, thus enabling the tilt angle of the support 1200 to be adjusted while achieving self-locking, allowing the furnace tube 200 to be tilted within a certain range of angles to meet the needs of the rotary kiln experimental device.

[0040] In the embodiments of this application, Figure 5 As shown, the driving component 400 in the rotary kiln experimental device may include: a first sprocket 401, a second sprocket 402, a synchronous chain 403, and an adjustable-speed motor 404. The first sprocket 401 is connected to the rotating shaft of the adjustable-speed motor 404, the second sprocket 402 can be fixedly connected to the side of the second rotating shaft 302, and the synchronous chain 403 can be wound around the first sprocket 401 and the second sprocket 402. In this way, the second rotating shaft 302 is driven by the cooperation of the sprocket and chain. The sprocket and chain can meet the transmission requirements of the rotary kiln experimental device with a wide temperature range and is suitable for use in dusty experimental environments.

[0041] For example, the working principle of the rotary kiln experimental device is schematically explained here: Remove the transparent window, feed the material into the furnace tube from the feed port, and install the observation mirror; after setting the heating temperature, heating rate and furnace tube speed on the console, start the speed regulating motor to drive the second shaft to drive the first shaft and the furnace tube to rotate; the electric heating wire heats up to make the material react in the furnace tube, and the movement state of the material in the furnace tube can be observed from the observation mirror position, and the real-time temperature of the material can be read through the material temperature measuring module in the furnace; after the material reaction is completed, stop heating and wait for the furnace tube to cool down to room temperature, remove the transparent window, and use a sampling spoon to take out the material for testing.

[0042] In summary, the rotary kiln experimental device provided in the embodiment of the present application may include: a housing, a furnace tube, a transmission shaft, and a drive component. The furnace tube in the rotary kiln experimental device is fixed on one side, that is, the first rotating shaft fixed to the furnace tube and the second rotating shaft connected to the drive component are detachably connected. In this way, when disassembling and replacing the furnace tube, the upper shell is separated from the lower shell, and the two rotating shafts are separated at the connection between the first rotating shaft and the second rotating shaft, so that the furnace tube can be removed. This effectively simplifies the replacement operation of the furnace tube in the rotary kiln experimental device, improves the efficiency of furnace tube replacement, and reduces labor costs. After the furnace tube is replaced with another furnace tube, the two rotating shafts are connected to restore the connection between the upper shell and the lower shell.

[0043] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless expressly limited otherwise.

[0044] The above description is merely an optional embodiment of the present application and is not intended to limit the present application.
