Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of a rotary kiln experimental apparatus provided in an embodiment of this application. Figure 2 yes Figure 1 The front view of the rotary kiln experimental apparatus shown is shown. Figure 3 yes Figure 1 The diagram shows a cross-sectional view of the rotary kiln experimental apparatus. The rotary kiln experimental apparatus may include: a shell 100, a furnace tube 200, a drive shaft 300, and a drive component 400.

[0035] The outer shell 100 of the rotary kiln experimental apparatus may include an upper shell 101 and a lower shell 102 that are disposed opposite to each other and movably connected. The upper shell 101 and the lower shell 102 can form a receiving cavity Q1. The side of the outer shell 100 has an opening Q2 communicating with the receiving cavity Q. For example, one end of the upper shell 101 and one end of the lower shell 102 can be rotatably connected by a hinge.

[0036] The furnace tube 200 in the rotary kiln experimental apparatus can be located inside the accommodating cavity Q1.

[0037] The drive shaft 300 in the rotary kiln experimental apparatus may include a first rotating shaft 301 and a second rotating shaft 302 coaxially arranged, with the first rotating shaft 301 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, while another portion of the first rotating shaft 301 may pass through the opening Q2 and be located outside the receiving cavity Q1 of the outer casing 100, and be detachably connected to the second rotating shaft 302. The drive component 400 may be drively connected to the second rotating shaft 302. For example, the side of the first rotating shaft 301 may have multiple connecting rods for fixed connection to the end of the furnace tube 200, and the multiple connecting rods may be distributed around the first rotating shaft 301. In other possible implementations, the first rotating shaft 301 and the furnace tube 200 may be an integral structure.

[0038] The drive component 400 can be configured to drive the second rotating shaft 302 to rotate while simultaneously driving the furnace tube 200 to rotate synchronously through the first rotating shaft 301.

[0039] In this embodiment, by fixing the furnace tube 200 in the rotary kiln experimental apparatus on one side, the first rotating shaft 301 fixed to the furnace tube 200 and the second rotating shaft 302 connected to the drive component 400 are detachably connected. Thus, when disassembling and replacing the furnace tube 200, the upper housing 101 and lower housing 102 are separated, and the two rotating shafts are separated at the connection point of the first rotating shaft 301 and the second rotating shaft 302, allowing the furnace tube 200 to be removed. This effectively simplifies the replacement operation of the furnace tube 200 in the rotary kiln experimental apparatus, improves furnace tube replacement efficiency, and reduces labor costs. After replacing the furnace tube with another type, the two rotating shafts are reassembled, and the connection between the upper housing 101 and the lower housing 102 is restored.

[0040] In summary, the rotary kiln experimental apparatus provided in this application embodiment can include: a shell, a furnace tube, a drive shaft, and a drive component. By fixing the furnace tube in the rotary kiln experimental apparatus 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 and second rotating shafts, so that the furnace tube can be removed. This effectively simplifies the furnace tube replacement operation in the rotary kiln experimental apparatus, improves the furnace tube replacement efficiency, and reduces labor costs. After replacing the furnace tube with another furnace tube, the two rotating shafts are connected again, and the upper shell and lower shell are reconnected.

[0041] Optional, please refer to Figure 4 , Figure 4This is a cross-sectional view of another rotary kiln experimental apparatus provided in this application embodiment. The end of the first rotating shaft 301 near the second rotating shaft 302 may have a first connecting flange 301a, and the end of the second rotating shaft 302 near 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 multiple bolts. In this way, the first rotating shaft 301 and the second rotating shaft 302 are detachably connected through two connecting flanges and multiple bolts, ensuring convenient assembly and disassembly of 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, one end of the first rotating shaft 301 and the second rotating shaft 302 may have a shaft hole, and the other end of the first rotating shaft 301 and the second rotating shaft 302 may be keyed to the shaft hole.

[0042] In this embodiment, the outer shell 100 may have a first heat-insulating member (not shown in the figure) fixed to the inner sidewall of the opening Q2 and sleeved on the first rotating shaft 301, and / or, the outer shell 100 may have a second heat-insulating member (not shown in the figure) fixed to the inner sidewall of the accommodating cavity Q1 and sleeved on the first rotating shaft 301 for covering the gap between the first rotating shaft 301 and the opening Q2. For example, in the first case, the outer casing 100 may have a first heat-insulating member fixed to the inner wall of the opening Q2 and sleeved on the first rotating shaft 301; in the second case, the outer casing 100 may have a second heat-insulating member 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; in the third case, the outer casing 100 may have a first heat-insulating member fixed to the inner wall of the opening Q2 and sleeved on the first rotating shaft 301, and the outer casing may also have a second heat-insulating member 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.

[0043] In this way, by providing a first heat-insulating element on the inner wall of the opening Q2 and / or providing a second heat-insulating element on the inner wall of the accommodating cavity Q1, heat loss in the furnace tube 200 can be effectively prevented, ensuring the full reaction of the material in the furnace tube 200.

[0044] Optional, such as Figure 4As shown, the rotary kiln experimental apparatus may further include: a heat insulation layer 500 fixed to the inner wall of the accommodating cavity Q1 of the outer shell 100 and surrounding the furnace tube 200, and an electric heating element 600 fixed to the side of the heat insulation layer 500 near the furnace tube 200. Thus, the electric heating element 600 can heat the furnace tube 200 to reach the required reaction temperature for the materials. Furthermore, the heat insulation layer 500 protects the furnace temperature inside the furnace tube 200, preventing a rapid drop in furnace temperature after the furnace tube 200 has been heated. For example, the electric heating element 600 may include multiple turns of electric heating wire fixed to the heat insulation layer 500, and the power of the electric heating wire can be controlled via a control panel in the rotary kiln experimental apparatus to arbitrarily adjust the heating temperature of the furnace tube 200.

[0045] In the embodiments of this application, such as Figure 4 As shown, the portion of the first rotating shaft 301 distributed within the furnace tube 200 includes a first branch pipe 301b and a second branch pipe 301c, both of which can be arranged perpendicular to the axial direction of the first rotating shaft 301. The rotary kiln experimental apparatus may further include: a wall temperature measuring module 700, a material temperature measuring module 800, and a control console (not shown in the figure). The wall temperature measuring module 700 can be installed at the end of the first branch pipe 301b, and the material temperature measuring module 800 can be installed at the end of the second branch pipe 301c. The control console can communicate with the wall temperature measuring module 700 and receive the temperature signal of the inner wall of the furnace tube 200 detected by the wall temperature measuring module 700. The control console can also communicate with the material temperature measuring module 800 and receive the temperature signal of the material within the furnace tube 200 detected by the material temperature measuring module 800.

[0046] It should be noted that temperature data is collected from two components: the inner wall of the furnace tube 200 and the material inside the furnace tube 200. Qualitative analysis is then performed on the collected data. 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 the length of the second branch tube 301c to ensure the accuracy of the wall temperature measurement module 700 in detecting the temperature of the inner wall of the furnace tube 200. Furthermore, due to gravity, the material inside the furnace tube 200 remains essentially at the bottom of the furnace tube 200 during its rotation. Therefore, the data measured by the material temperature measurement module 800 can be used to analyze the temperature changes of the material.

[0047] For example, the console may include a control unit and a display screen. The control unit can communicate with the display screen and the wall temperature measurement module and material temperature measurement module, respectively. For instance, the control unit may include a PLC control system and a wireless communication module. The temperature signal collected by the temperature measurement module can be sent to the PLC control system without a communication module. The display screen can communicate with the PLC control system via a signal converter. It should be noted that the wall temperature measurement module 700 and the material temperature measurement module 800 can also be externally connected via signal lines. Both the first rotating shaft 301 and the second rotating shaft 302 can be hollow shafts, and the first rotating shaft 301 can be connected to the first branch pipe 301b and the second branch pipe 301c, thus facilitating the transmission of the temperature signal detected by the temperature measurement module via the signal line. Here, both the wall temperature measurement module 700 and the material temperature measurement module 800 can be temperature sensors.

[0048] In this application, as Figure 4 As shown, the upper housing 101 may also have a first mounting hole a1, and the insulation layer 500 may have a second mounting hole a2 communicating with the first mounting hole a1. The rotary kiln experimental apparatus may further include an auxiliary temperature measuring module 900 installed in the first mounting hole a1 and the second mounting hole a2. The control console may be electrically connected to the auxiliary temperature measuring module 900 and receive the temperature signal of the electric heating component 600 detected by the auxiliary temperature measuring module 900. In this way, the temperature of the electric heating component 600 can be detected in real time through the auxiliary temperature measuring module 900, so as to achieve precise adjustment of the heating temperature of the electric heating component 600. Here, the auxiliary temperature measuring module 900 can be a temperature sensor.

[0049] Optional, such as Figure 4 and Figure 5 As shown, Figure 5 This is a schematic diagram of another rotary kiln experimental apparatus provided in this application embodiment. The outer shell 100 may have a feed inlet Q3 on the side opposite to the opening Q2. The rotary kiln experimental apparatus may also include a clamping ring 1000 and a transparent viewing window 1100. The clamping ring 1000 can be fixed to the edge of the feed inlet Q3 outside the outer shell 100, and the transparent viewing window 1100 can be installed inside the clamping ring 1000 and cover the feed inlet Q3. Thus, by setting the transparent viewing window 1100 at the feed inlet Q3, it is possible to observe the movement trajectory and reaction state of the material inside the furnace tube 200 in real time. When loading material into the furnace tube 200, the transparent viewing window 1100 is easily detached from the clamping 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 viewing window 1100 can be a plate-like structure made of high-temperature resistant quartz glass.

[0050] In the embodiments of this application, such as Figure 5As shown, the rotary kiln experimental apparatus may further include: a support 1200, and a first support beam 1300 and a second support beam 1400 fixed on the support 1200. The first support beam 1300 can be connected to the lower shell 102, and the second support beam 1400 can be rotatably connected to the second rotating shaft 302. In this way, the support 1200 and the two support beams provide stable support for the outer shell 100 and the drive component 400.

[0051] For example, such as Figure 4 and Figure 5 As shown, the top of the second support beam 1400 can be connected to a sleeve 1401, and a graphite bushing 1402 is fixed to the inner side wall of the sleeve 1401. The end of the second rotating shaft 302 can be located inside the graphite bushing 1402 and rotatably connected to the graphite bushing 1402.

[0052] Optional, such as Figure 5 As shown, two adjacent corners of the support 1200 can have casters 1201, and two other adjacent corners can have adjusting wheels 1202 threadedly connected to the support 1200. This allows for convenient movement of the rotary kiln experimental apparatus through the cooperation of the casters 1201 and adjusting wheels 1202. Furthermore, the adjusting wheels 1202 can be threadedly connected to the support 1200, thus enabling adjustment of the tilt angle of the support 1200 while maintaining self-locking, allowing the furnace tube 200 to tilt within a certain angle range to meet the experimental needs of the rotary kiln experimental apparatus.

[0053] In the embodiments of this application, such as Figure 5 As shown, the drive component 400 in the rotary kiln experimental apparatus may include: a first sprocket 401, a second sprocket 402, a synchronous chain 403, and a variable speed motor 404. The first sprocket 401 is connected to the rotating shaft of the variable 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 sprockets and the chain. The sprocket and chain can adapt to the transmission requirements of the large temperature range of the rotary kiln experimental apparatus and is suitable for use in experimental environments with a lot of dust.

[0054] For example, the working principle of the rotary kiln experimental apparatus is illustrated here:

[0055] Remove the transparent window. The material needs to be fed into the furnace tube through the feed inlet. Install the observation window. After setting the heating temperature, heating rate, and furnace tube speed on the control panel, start the speed-regulating motor to drive the second shaft to rotate the first shaft and the furnace tube. The electric heating wire heats up the material to react inside the furnace tube. The movement of the material inside the furnace tube can be observed through the observation window. The real-time temperature of the material is read through the material temperature measurement module inside the furnace. After the material reaction is complete, heating stops and the furnace tube is allowed to cool down to room temperature. Remove the transparent window and use a sampling spoon to take out the material for testing.

[0056] In summary, the rotary kiln experimental apparatus provided in this application embodiment can include: a shell, a furnace tube, a drive shaft, and a drive component. By fixing the furnace tube in the rotary kiln experimental apparatus 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 and second rotating shafts, so that the furnace tube can be removed. This effectively simplifies the furnace tube replacement operation in the rotary kiln experimental apparatus, improves the furnace tube replacement efficiency, and reduces labor costs. After replacing the furnace tube with another furnace tube, the two rotating shafts are connected again, and the upper shell and lower shell are reconnected.

[0057] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0058] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
