Detailed implementation manner

[0031] To further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.

[0032] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] As Figures 1 to 9 shown, a high-temperature physical purification furnace for graphite raw materials provided by an embodiment of the present invention includes a furnace body 1, a sealing door 4, a heating pipe 9 and a control panel 5. The sealing door 4 is hinged to the front of the furnace body 1, the control panel 5 is fixedly installed on one side of the furnace body 1, the heating pipe 9 is fixedly installed inside the furnace body 1, and a temperature sensor 11 is arranged inside the furnace body 1;

[0034] A discharging tank 6 is fixed inside the furnace body 1 through a limit ring 10, a movable sleeve 7 is movably sleeved inside the discharging tank 6, and a driving mechanism 3 is connected to one side of the movable sleeve 7;

[0035] A stirring motor 8 is fixedly installed at the upper end of the movable sleeve 7, and a gear ring 705 is fixedly connected to the inner wall of the movable sleeve 7. The output end of the stirring motor 8 is connected to a stirring mechanism 2.

[0036] Specifically, the heating tube 9, the temperature sensor 11, the drive motor 302, and the stirring motor 8 are all electrically connected to the control panel 5. During use, the heating tube 9 is controlled to start by operating the external control panel 5 to heat the furnace body 1. The temperature inside the furnace is monitored by the temperature sensor 11. When the temperature exceeds the safety threshold, the heating tube 9 stops heating to avoid safety problems such as equipment failure and fire caused by excessive temperature. The temperature value is displayed through the control panel 5, which helps the operator adjust the temperature inside the furnace to ensure the purification quality.

[0037] Preferably in the present invention, a limiting ring 10 is fixedly installed on the inner bottom wall of the furnace body 1. The outer peripheral surface of the feeding tank 6 is in interference fit with the inner wall of the limiting ring 10. The outer peripheral surface of the movable sleeve 7 is slidably connected up and down with the inner wall of the feeding tank 6. An installation block 703 and three guide blocks 701 are fixedly connected to the outer peripheral surface of the movable sleeve 7. The installation block 703 and the three guide blocks 701 are arranged in a circular pattern on the movable sleeve 7. Three guide rods 702 are slidably connected up and down inside the three guide blocks 701, and the tops of the three guide rods 702 are fixedly connected to the inner top wall of the furnace body 1.

[0038] Specifically, by setting the limiting ring 10, the feeding tank 6 can be accurately placed inside the limiting ring 10, enabling the feeding tank 6 to maintain its position more stably during the processing. By setting the three guide blocks 701 and the guide rods 702, guidance and support can be provided for the up and down movement of the movable sleeve 7, enabling it to move along the guide rods 702 and preventing the movable sleeve 7 from shifting or tilting, thereby improving the stability of the movement of the movable sleeve 7.

[0039] Preferably in the present invention, an annular slide rail 704 is fixedly installed on the inner wall of the movable sleeve 7. The gear ring 705 is fixedly connected to the inner side wall of the annular slide rail 704. The top end of the movable sleeve 7 is fixedly connected to a mounting bracket 801, and the stirring motor 8 is fixedly installed on the mounting bracket 801. The output end of the stirring motor 8 is fixedly connected to a support shaft 802, and a stop block 803 is fixedly connected to the bottom of the support shaft 802.

[0040] Specifically, the chute opening of the annular slide rail 704 is arranged on the lower surface, which can prevent the graphite material from falling into the chute during feeding and affecting the movement of the slider 209. By setting the annular slide rail 704, the slider 209 can move along a specific track, avoiding deviation and improving the accuracy and stability of the movement of the slider 209. The annular slide rail 704 and the gear ring 705 can also provide sufficient support force for the movable sleeve 7 to ensure that the movable sleeve 7 will not deform during operation and movement.

[0041] The rotating plate 201 in the stirring mechanism 2 is fixedly sleeved on the lower end of the support shaft 802. The bottom of the support shaft 802 is provided with a stopper 803 to provide auxiliary support for the rotating plate 201, thereby improving the stability of the middle part of the rotating plate 201. When working, the stirring motor 8 is started to drive the support shaft 802 and the stirring mechanism 2 to rotate, and the graphite material is stirred by the stirring mechanism 2 to ensure that the graphite material is heated evenly.

[0042] As a preferred embodiment of the present invention, the stirring mechanism 2 includes a driven gear 206 and a plurality of rotating shafts 203 arranged on both sides of the stirring motor 8, the driven gears 206 on both sides are meshed and connected with the gear ring 705, and the rotating shafts 203 on both sides are respectively connected by a chain 208 and a sprocket 207 for transmission, and each rotating shaft 203 is circumferentially provided with a plurality of stirring blades 204, and the bottom of each rotating shaft 203 can be detachably provided with a scraping tooth 205 for scraping the bottom of the discharge tank 6, and the stirring mechanism 2 also includes a rotating plate 201, which is fixedly sleeved on the lower end of the support shaft 802, and the bottom of the rotating plate 201 abuts against the block 803, and both ends of the rotating plate 201 are fixedly connected with a slider 209, and the slider 20 9 is slidably connected in the annular slide rail 704, and protective covers 202 are fixedly connected on both sides of the upper surface of the rotating plate 201. The two protective covers 202 are respectively covered on the outside of the sprockets 207 and chains 208 on both sides. Each sprocket 207 is correspondingly fixedly sleeved on the upper end of the rotating shaft 203, and the sprockets 207 on both sides are respectively meshed and connected with the two chains 208. The two driven gears 206 are respectively fixedly mounted on the top of the two rotating shafts 203 on the outer edge, and a retaining ring 210 is sleeved on the lower end of each rotating shaft 203. A groove 211 is opened on the shaft body of the rotating shaft 203 below the retaining ring 210, and a retaining spring 212 is clamped in the groove 211. The scraping tooth 205 is fixedly mounted between the retaining ring 210 and the retaining spring 212.

[0043] During specific installation, the rotating shaft 203 is rotatably installed on the rotating plate 201, and its upper end penetrates through the rotating plate 201. The protective cover 202 can prevent materials from falling on the chain 208 or the sprocket 207, affecting the transmission between them, and can also prevent material jamming. The rotating shaft 203, the sprocket 207, the stirring blade 204, and the scraping teeth 205 form a stirring unit. A number of stirring units are arranged on both sides of the rotating plate 201. Taking one side as an example, the upper end of each stirring unit is connected to the sprocket 207 through the chain 208 to achieve synchronous rotation of the rotating shaft 203, improving the transmission efficiency. The outermost rotating shaft 203 is engaged with the gear ring 705 through the driven gear 206 at the top. When the rotating plate 201 rotates, the slider 209 slides along the inner wall of the annular slide rail 704, driving a number of rotating shafts 203 to rotate synchronously around the support shaft 802. While the driven gear 206 rotates around the support shaft 802, it also rotates around the rotating shaft 203 inside it, thereby driving the sprocket 207 to rotate. The chain 208 drives the rotating shaft 203 and the stirring blade 204 on this side to rotate synchronously to stir the materials. By setting a number of stirring blades 204 with different installation angles, the moving direction of the materials can be changed, improving the dispersion effect. And through the above settings, a larger stirring range can be covered, ensuring that the materials can be fully stirred in all directions, improving the stirring and heating effects, and improving the working efficiency.

[0044] By setting a circlip 212 at the bottom of the rotating shaft 203, it is convenient for the installation and disassembly of the scraping teeth 205, improving the convenience of later maintenance. By sleeving the middle part of the scraping teeth 205 on the rotating shaft 203 so that the scraping teeth 205 are located between the retaining ring 210 and the circlip 212, the stability of the scraping teeth 205 can be improved. By setting the scraping teeth 205 to rotate with the rotating shaft 203, the materials at the bottom can be effectively stirred up, improving the fluidity of the materials, making the stirring more uniform, and preventing the materials from adhering to the inner wall of the bottom of the discharging tank 6, reducing material residue and accumulation, and keeping the inside of the discharging tank 6 clean.

[0045] Preferably, the driving mechanism 3 includes a driving motor 302, a mounting seat 301, a driving gear 303, and a rack 304. The mounting seat 301 is located below the mounting block 703, and its bottom is fixedly connected to the inner wall of the bottom of the furnace body 1. The driving motor 302 is fixedly installed on one side of the mounting seat 301. The driving gear 303 is fixedly connected to the output end of the driving motor 302. The upper end of the rack 304 is fixedly connected to the mounting block 703. The driving gear 303 is located inside the mounting seat 301, and the driving gear 303 is meshed with the rack 304.

[0046] During specific settings, after the stirring and heating operations are completed, the driving motor 302 is started to drive the driving gear 303 to rotate. Through the meshing connection between the driving gear 303 and the rack 304, the rack 304 drives the mounting block 703 and the movable sleeve 7 to move upward until the movable sleeve 7 moves above the discharging tank 6, facilitating the removal of the discharging tank 6 for discharging.

[0047] The working principle of the present invention:

[0048] Place the discharging tank 6 within the limit ring 10, pour in the graphite raw material, start the driving motor 302 to drive the driving gear 303 to rotate. The driving gear 303 drives the rack 304 to move downward, thereby driving the movable sleeve 7 and the stirring mechanism 2 to move downward, causing the lower end of the stirring mechanism 2 to insert into the graphite raw material. Subsequently, turn on the heating tube 9 through the control panel 5, set the heating temperature, and start the stirring motor 8. The stirring motor 8 drives the support shaft 802 and the rotating plate 201 to rotate. The sliders 209 at both ends of the rotating plate 201 slide along the annular slide rail 704. A plurality of rotating shafts 203 rotate around the support shaft 802. The driven gear 206 drives the stirring blades 204 and the scraping teeth 205 to rotate around the rotating shafts 203 through cooperation with the toothed ring 705. During the movement process, the material is fully stirred to avoid material caking or uneven heating, improving the heating purification effect and work efficiency. After heating is completed, the driving motor 302 drives the driving gear 303 to rotate in the reverse direction, moving the movable sleeve 7 above the discharging tank 6, facilitating the removal of the discharging tank 6 for discharging.

[0049] In summary: For this high-temperature physical purification furnace for graphite raw materials, the heating tube 9 is controlled by the control panel to start heating the furnace body 1. The temperature sensor 11 monitors the temperature inside the furnace. When the temperature exceeds the safety threshold, the heating tube 9 stops heating to avoid safety problems such as equipment failures and fires caused by excessive temperature. The temperature value is displayed through the control panel 5, which helps the operator adjust the temperature inside the furnace to ensure the purification quality. The stirring motor 8 drives a plurality of rotating shafts 203, stirring blades 204, and scraping teeth 205 to rotate, causing the rotating shafts 203, stirring blades 204, and scraping teeth 205 to rotate around the support shaft 802. By further arranging a driven gear 206 on the outer rotating shaft 203 to mesh with the toothed ring 705 and cooperating with the transmission of the chain 208 and the sprocket 207, while the rotating shafts 203, stirring blades 204, and scraping teeth 205 rotate around the support shaft 802, they also rotate around the vertical center line of the rotating shaft 203. This can not only improve the material turning efficiency but also expand the stirring range, ensuring that the material is fully stirred in all directions, improving the stirring and heating efficiency, and thus enhancing the work efficiency.
