[0042] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present invention.

[0043] Example 1:

[0044] The present invention provides a mechanized charging and discharging system for the graphitization purification process of anode materials. Referring to Figure 1 as shown, the mechanized charging and discharging system for the graphitization purification process of the anode material includes a conveyor device 1, a raw material feeding device 2, a raw material suction and discharge device 3, a graphitization furnace chamber 4, a clinker suction and discharge device 5, and a clinker discharging device 6.

[0045] The conveying device 1 includes a traveling device, and the traveling device is provided with a raw material lifting mechanism 7 for lifting or releasing the raw material suction and discharge device 3. The raw material feeding device 2 can extract the raw material in the raw material package and convey it to the raw material suction and discharge device 3. A grid box 41 is arranged in the graphitization furnace chamber 4. The clinker suction and discharge device 5 is arranged on the traveling device, and the clinker discharging device 6 can discharge the clinker into the clinker package.

[0046] During use, the raw material feeding device 2 extracts the raw material in the raw material package and conveys it to the raw material suction and discharge device 3. The traveling device moves to the raw material feeding device 2, extracts the raw material suction and discharge device 3 through the raw material lifting mechanism 7, and conveys it to the grid box 41. The raw material suction and discharge device 3 unloads the raw material into the grid box 41.

[0047] After that, the clinker suction and discharge device 5 sucks the clinker in the grid box 41. The traveling device drives the clinker suction and discharge device 5 to the clinker discharging device 6 and unloads the clinker into the clinker discharging device 6. The clinker discharging device 6 discharges the clinker into the clinker package.

[0048] In the above process, through the mutual cooperation of the conveying device 1, the raw material feeding device 2, the raw material suction and discharge device 3, the clinker suction and discharge device 5 and the clinker discharging device 6, the mechanization of loading and unloading the negative electrode material can be realized, without the need for too much manual participation, which can effectively avoid the introduction of impurities caused by human participation. Not only is the production effect remarkable and the production efficiency high, but also the dust emission phenomenon can be significantly reduced, and the health hazards caused by excessive dust to the human body can be eliminated.

[0049] Embodiment 2:

[0050] Embodiment 2 is based on Embodiment 1:

[0051] As Figures 1 - 3 shown, the traveling device includes a trolley traveling mechanism 11, a car traveling mechanism 12 and a raw material transfer trolley 13.

[0052] The trolley traveling mechanism 11 is arranged on the workshop crane beam and runs along the length direction of the workshop. The main beam frame of the trolley traveling mechanism 11 adopts an offset box-shaped double-beam bridge frame, which has a reasonable layout, high strength and strong load-bearing capacity. An insulating layer is arranged at the bottom of the beam frame, which can effectively prevent the problem of the beam being heated and deformed due to the heat radiation of the graphitization furnace. The driving part of the trolley traveling mechanism 11 adopts a three-in-one motor reducer of a driving motor, a reduction box and a brake, and is equipped with an inverter and an encoder, and the speed and traveling distance can be set according to actual needs.

[0053] The trolley traveling mechanism 12 is arranged on the bridge girder of the gantry traveling mechanism 11. On the one hand, it can move synchronously with the gantry traveling mechanism 11. On the other hand, it can run along the width direction of the workshop. The trolley traveling mechanism 12 also adopts a three-in-one motor reducer of a drive motor, a speed reducer and a brake, and is equipped with an inverter and an encoder.

[0054] The raw material lifting mechanism 7 and the clinker suction and discharge device 5 are both arranged on the trolley traveling mechanism 12.

[0055] The gantry traveling mechanism 11 and the trolley traveling mechanism 12 cooperate with each other, and the raw material and clinker conveying effects are remarkable.

[0056] As Figure 6 shown, a raw material silo placement station is arranged on the raw material transfer trolley 13, and the raw material suction and discharge device 3 is placed on the raw material silo placement station.

[0057] A plurality of the raw material silo placement stations are arranged on the raw material transfer trolley 13. During use, the rotation of the raw material suction and discharge device 3 can be realized, the waiting time of the raw material suction and discharge device 3 can be effectively saved, and the production efficiency can be improved.

[0058] As an optional implementation manner, as Figure 13 shown, the raw material lifting mechanism 7 includes a traction type lifting mechanism 71 and a buffer hanger 72. The traction type lifting mechanism 71 is arranged on the trolley traveling mechanism 12, and the buffer hanger 72 is connected to the traction end of the traction type lifting mechanism 71.

[0059] When extracting or releasing the raw material suction and discharge device 3, the traction section of the traction type lifting mechanism 71 drives the lifting of the buffer hanger 72, thereby realizing the lifting of the raw material suction and discharge device 3.

[0060] The traction type lifting mechanism 71 includes two winch hoists 711. The traction ends of the two winch hoists 711 are connected and arranged on both sides of the buffer hanger 72. During actual use, the buffer hanger 72 is lifted or lowered by the forward or reverse rotation of the winch hoist 711. The two winch hoists 711 cooperate with each other through an encoder and an inverter to ensure the synchronization and stability of the lifting of the two.

[0061] A weight sensing device is arranged on the bottom side of the drum of each winch hoist 711. Preferably, the weight sensing device adopts a bearing seat type lifting limiter, which is convenient for real-time monitoring of the lifting weight of the two winch hoists 711, and can effectively prevent overload phenomena such as tilting and jamming caused by uneven lifting weights on both sides, and is safe and reliable in use.

[0062] As Figure 14 and Figure 15As shown, the buffer hanger 72 includes a hanger body 721, and hanging feet 722 are symmetrically provided on both sides of the hanger body 721. The two ends of the hanger body 721 are connected by a buffer member 723 and a connecting frame 724 is provided. The buffer hanger 72 with a buffering effect makes the extraction or release process of the raw material suction and unloading device 3 smoother.

[0063] As an optional embodiment, Figures 14 - 16 As shown, the raw material lifting mechanism 7 includes a guide mechanism 73 , and the guide mechanism 73 includes a guide column 731 and a guide wheel 732 that rolls with the guide column 731 .

[0064] The guide columns 731 are arranged on the trolley traveling mechanism 12 and are located on both sides of the trolley traveling mechanism 12 , and the guide wheels 732 are arranged on the connecting frame 724 .

[0065] The setting of the guide mechanism 73 can effectively limit the lifting trajectory of the buffer hanger 72, thereby avoiding its shaking during the lifting process and improving the stability of the raw material suction and discharge device 3 during the extraction and release process.

[0066] The guide mechanism 73 adopts rolling friction, which ensures the guiding effect with low loss and long service life of the equipment.

[0067] As an optional embodiment, Figures 4 - 6 As shown, the raw material feeding device 2 includes a raw material unpacking device 21 and a raw material suction device 22 .

[0068] The raw material unpacking device 21 includes a raw material bag lifting mechanism 211 and a raw material buffer silo 212. The raw material bag lifting mechanism 211 adopts an electric hoist. The raw material bag lifting mechanism 211 is arranged above the raw material buffer silo 212. A feed port is provided at the top of the raw material buffer silo 212. A vibrating hopper 213 is provided at the position of the feed port. A discharge port is provided at the bottom of the raw material buffer silo 212. The raw material suction device 22 is connected to the discharge port through a pipeline.

[0069] During the feeding process, the raw material bag lifting mechanism 211 lifts the raw material bag so that it corresponds to the feeding port, and then opens the bottom discharge port of the raw material bag. The raw material falls into the raw material buffer bin 212 through the vibrating hopper 213. During this process, the vibrating hopper 213 is started, and the discharge is promoted by vibration, and the feeding effect is significant.

[0070] The raw material buffer silo 212 is connected to a vacuum pump, which is started when feeding to form a negative pressure and effectively prevent dust from escaping.

[0071] As an optional embodiment, Figures 4 - 6 As shown, the raw material suction device 22 includes a raw material suction bin 221 and a pressing and sealing device 222 .

[0072] The raw material suction bin 221 is connected to the discharge port through a pipeline. A first air lock 223 is arranged at the bottom of the raw material suction bin 221. The raw material suction bin 221 uses negative pressure to suck the raw material from the raw material buffer bin 212 into its interior.

[0073] As Figure 7 shown, the pressing and sealing device 222 includes a pressing telescopic mechanism 2221, a pressing member 2222 and a hose joint 2223. The telescopic end of the pressing telescopic mechanism 2221 is connected to the pressing member 2222. One end of the hose joint 2223 is connected to the first air lock 223, and the other end of the hose joint 2223 is arranged on the pressing member 2222.

[0074] During feeding, the raw material transfer trolley 13 transports the raw material suction and discharge device 3 to directly below the raw material suction bin 221 and aligns the other end of its hose joint 2223 with the raw material inlet of the raw material suction and discharge device 3. At this time, the telescopic end of the pressing telescopic mechanism 2221 extends, driving the pressing member 2222 to press down until the hose joint 2223 is pressed onto the raw material inlet, thereby forming a sealed material conveying channel, which can ensure the feeding effect while avoiding dust emission.

[0075] Preferably, the pressing telescopic mechanism 2221 adopts a pneumatic telescopic mechanism.

[0076] As an alternative implementation, as Figure 13 and Figure 17 shown, the raw material suction and discharge device 3 includes a raw material bin 31 and a degassing spiral packing device 32.

[0077] Lifting lugs 311 are arranged on the outer wall of the raw material bin 31. During lifting, the suspension feet 722 of the buffer suspension bracket 72 move to directly below the corresponding lifting lugs 311 under the drive of the traction type lifting mechanism 71, the trolley traveling mechanism 12 and the gantry traveling mechanism 11, so as to realize the extraction and release of the raw material bin 31.

[0078] The raw material bin 31 is made of 304 stainless steel, and its inner wall is mirror polished.

[0079] A raw material inlet is arranged at the top of the raw material bin 31, and a raw material discharge port is arranged at the bottom of the raw material bin 31. A second air lock 33 is arranged at the raw material discharge port.

[0080] The degassing spiral packing device 32 includes a discharging bin 321 and a conveying pipe 322 vertically connected to the bottom of the discharging bin 321. The discharging bin 321 is connected to the second air lock 33, and a spiral roller 323 is arranged in the conveying pipe 322.

[0081] During the furnace charging process, the degassing screw packing device 32 moves with the raw material silo 31 to the upper part of the corresponding grid box 41, and the raw material is charged into the grid box 41 through the degassing screw packing device 32, thus completing the raw material furnace charging before the graphitization of the negative electrode material.

[0082] To improve the furnace charging efficiency, the degassing screw packing device 32 has multiple sets of discharging bins 321, feeding pipes 322 and screw rollers 323.

[0083] Through the degassing screw packing device 32 with screw rollers 323, by adopting double measures of degassing and compaction, the dust-free, rapid and dense filling process can be realized.

[0084] As an optional implementation mode, as Figure 8 、 Figure 9 and Figure 18 shown, the clinker suction and discharge device 5 includes a gas-solid separator 51, an air cannon arch breaking device 52, a suction pipe 53 and a discharge pipe 54.

[0085] The gas-solid separator 51 is arranged on the trolley traveling mechanism 12. The gas-solid separator 51 combines a storage bin, a primary cyclone filter and a secondary bag filter, which can effectively avoid the material segregation phenomenon that occurs in the existing clinker silo during the suction process and can effectively ensure the homogeneity of the material.

[0086] A weighing sensor is installed in the bin body of the gas-solid separator 51 for real-time monitoring of its internal weight, which can effectively avoid the occurrence of overload phenomenon.

[0087] The bin body of the gas-solid separator 51 is made of 304 stainless steel, and its inner wall is mirror-polished.

[0088] An air cooler is connected to the gas-solid separator 51 for cooling the clinker.

[0089] The air cannon arch breaking device 52 is connected to the bin body of the gas-solid separator 51.

[0090] Since the negative electrode material belongs to ultrafine powder, it will accumulate together after the bin is full. Coupled with the discharge of the internal air, the fluidity of the negative electrode material will become poor, resulting in an arching phenomenon. The setting of the air cannon arch breaking device 52 can break up the arch by high-speed air flow, making the discharging more smooth.

[0091] The suction pipe 53 is connected to the bin body along the tangential direction of the bin body. The suction pipe 53 can suck the clinker in the graphitization furnace chamber 4, and the suction effect is remarkable.

[0092] The discharge pipe 54 is connected to the bin body. The discharge pipe 54 can discharge the clinker in the bin body into the clinker discharging device 6.

[0093] As an alternative implementation, as Figures 8 - 12 shown, the material suction pipe 53 is arranged as a telescopic material suction pipe, and the telescopic material suction pipe includes an outer layer pipe 531, an elastic joint 532, an inner layer pipe 533, a deviation correction and yaw limiting mechanism 534, and a traction mechanism 535. The traction mechanism 535 adopts a double-rope winch and is controlled by frequency conversion.

[0094] The top end of the outer layer pipe 531 is connected to the silo body through the elastic joint 532. The inner layer pipe 533 is slidably arranged inside the outer layer pipe 531. The deviation correction and yaw limiting mechanism 534 is connected to the outer layer pipe 531, and the traction end of the traction mechanism 535 is connected to the inner layer pipe 533.

[0095] During the process of discharging from the furnace, the trolley traveling mechanism 11 and the small vehicle traveling mechanism 12 drive the clinker suction and discharge device 5 to move above the grid box 41. At this time, the traction end of the traction mechanism 535 drives the inner layer pipe 533 to move downward and insert into the grid box 41. After that, the telescopic material suction pipe sucks the clinker in the grid box 41, thus completing the furnace discharging operation.

[0096] During the telescopic process of the material suction telescopic pipe, the deviation correction and yaw limiting mechanism 534 can effectively correct the relative position of the material suction telescopic pipe and avoid damage caused by accidental excessive yaw.

[0097] As an alternative implementation, as Figure 19 and Figure 20 shown, the clinker discharging device 6 includes a clinker buffer silo 61 and a clinker bagging device 62.

[0098] The clinker bagging device 62 includes a clinker suction silo 621 and a degassing silo 622. A clinker inlet is arranged at the top of the clinker buffer silo 61. The clinker discharge port of the clinker buffer silo 61 is connected to the clinker suction silo 621 through a pipeline. A third air lock 623 is arranged at the bottom of the clinker suction silo 621.
