Description

Technical Field

[0001] The invention relates to the technical field of graphite crucible fillers, in particular to a semi-automatic multi-station crucible loading machine. Background Art

[0002] When graphite materials are used to prepare negative electrode materials for lithium-ion batteries, it is necessary to first crush the block or large-granular graphite precursor into powder particles, then load the powder particles into a crucible, and place the crucible into a carbonization furnace or a graphitization furnace for carbonization and graphitization treatment. Currently, the process of loading graphite precursor powder particles into a crucible is usually automatically filled using a graphite crucible filling machine.

[0003] The existing graphite crucible filling machine usually places the crucible on a hydraulic lifting platform, drives the crucible to rise through the hydraulic lifting platform, and connects the crucible with the material bin discharge port for filling.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This semi-automatic multi-station crucible loading machine is equipped with a hydraulic lifting mechanism. When filling the crucible, the hydraulic telescopic rod is contracted to pull the lifting frame downward, and the lifting frame drives the vertical rod to slide downward in the middle of the guide block to guide the lifting of the lifting frame. At the same time, the lifting frame drives the eight-cone material bin to move downward, and the eight-cone material bin drives the discharge pipe and the sealing platform of the crucible mouth to move downward and dock with the crucible, so that the discharge pipe is connected with the crucible through the discharge port for filling. The filling process relies on the hydraulic lifting mechanism to drive the eight-cone material bin to descend and dock with the crucible, which changes the way that the traditional equipment adopts the crucible to rise to receive materials and avoids the shaking or even tipping of the crucible during the lifting process.

[0015] 2. This semi-automatic multi-station crucible loading machine is equipped with an eight-cone silo and a crucible mouth sealing platform. The bottom of the eight-cone silo is connected with eight feeding pipes. When the eight-cone silo descends, the eight feeding pipes are respectively connected with the eight crucibles, so as to realize multi-station efficient filling and greatly speed up the working efficiency of crucible filling. In addition, when the feeding pipe is connected with the crucible, the crucible mouth sealing plate is pressed on the upper surface of the crucible. On the one hand, it is used to squeeze the crucible to stably receive the material on the vibration platform, and on the other hand, the crucible is sealed to prevent powder particles from floating upward during the falling process of the material.

[0016] 3. This semi-automatic multi-station crucible loading machine is equipped with a vibration platform. During the process of receiving materials from the crucible, the vibration telescopic rod frequently extends and retracts to drive the vibration platform to vibrate, and the vibration platform drives the crucible to vibrate, so that the material inside the crucible is vibrated and compacted, thereby increasing the filling rate of the material in the crucible.

[0017] 4. This semi-automatic multi-station crucible loading machine is equipped with a stirring shaft and a V-shaped stirring rod. When the material in the eight-cone silo falls, the driving motor drives the stirring shaft to rotate, and the stirring shaft drives the V-shaped stirring rod to rotate. The V-shaped stirring rod breaks up the material to prevent the material from forming an arch bridge that affects the discharge of the material.

[0018] 5. This semi-automatic multi-station crucible loading machine is provided with a feeding pipe, a first dust removal installation port and a second dust removal installation port. By setting the feeding pipe to a double wall, when the material enters the eight-cone silo from the feeding pipe, the dust enters the dust suction channel from the dust suction hole and enters the first bag dust collector from the first dust removal installation port. The material falling in the eight-cone silo causes dust, and the dust enters the second bag dust collector from the second dust removal installation port, thereby achieving the effect of dust removal of the dust generated by material feeding and unloading, and preventing dust from floating and polluting the working environment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figures 1 to 7 As shown, the semi-automatic multi-station crucible loading machine of this embodiment includes a frame 1, a feeding platform 2 installed on the top of the frame 1, a walking staircase 3 installed on one side of the feeding platform 2, and a power distribution cabinet 9 installed on one side of the frame 1. A feeding pipe 4 is installed through the center of the feeding platform 2, which is used to pour the materials in the ton bag into the eight-cone silo 5. An eight-cone silo 5 is arranged below the feeding pipe 4, and a crucible mouth sealing platform 6 is connected below the eight-cone silo 5. A vibration platform 7 is arranged below the crucible mouth sealing platform 6. A crucible 8 is movably placed on the upper surface of the vibration platform 7, and eight crucibles 8 are placed on the vibration platform 7. Both left and right sides of the frame 1 are connected with beams 10 for installing hydraulic telescopic rods 112 and support rods 113. A hydraulic lifting mechanism 11 is installed on the upper surface of the beam 10 for driving the eight-cone silo 5 to move downward into the filler in the crucible 8; The hydraulic lifting mechanism 11 includes a lifting frame 111, and hydraulic telescopic rods 112 are connected to the four corners of the bottom of the lifting frame 111. There are four hydraulic telescopic rods 112, which are symmetrically arranged relative to the lifting frame 111. The four hydraulic telescopic rods 112 are connected to the same hydraulic pump and cylinder to achieve synchronous extension and retraction. A support rod 113 is arranged on one side of the hydraulic telescopic rod 112. The support rod 113 is used to support the lifting frame 111 when the hydraulic telescopic rod 112 is retracted. Vertical rods 114 are vertically connected to the inner walls on both sides of the lifting frame 111, and guide blocks 115 are slidably connected to the upper and lower ends of the vertical rods 114.

[0025] Specifically, the lifting frame 111 is in the shape of a rectangular frame, and the inner walls on the front and rear sides of the lifting frame 111 are connected to the front and rear side walls of the eight-cone silo 5. When the lifting frame 111 is lifted or lowered, the lifting frame 111 drives the eight-cone silo 5 to lift or lower. The hydraulic telescopic rod 112 and the support rod 113 are both installed on the crossbeam 10. The telescopic end of the hydraulic telescopic rod 112 is connected to the lifting frame 111. The hydraulic telescopic rod 112 contracts to pull the lifting frame 111 downward, and the lifting frame 111 drives the eight-cone silo 5 downward. The eight-cone silo 5 drives the discharge pipe 51 and the crucible mouth sealing platform 6 to move downward and dock with the crucible 8, so that the discharge pipe 51 is connected to the crucible 8 through the discharge port 61 for filling. This changes the way in which the traditional equipment uses the crucible 8 to rise to receive materials, and avoids the shaking or even tipping of the crucible 8 during the lifting and lowering process.

[0026] Furthermore, the guide block 115 is composed of two L-shaped blocks. There are four L-shaped blocks, and two of them are symmetrically distributed on the inner wall of the top of the crossbeam 10 and the frame 1 in a group. The spacing between the two L-shaped blocks is adapted to the width of the vertical rod 114. The upper and lower ends of the vertical rod 114 are inserted between the two L-shaped blocks. When the lifting frame 111 is lifted or lowered, the vertical rod 114 is driven to lift or lower, so that the upper and lower ends of the vertical rod 114 slide and lift in the guide block 115, guiding the lifting of the lifting frame 111.

[0027] Furthermore, a dust suction hole 41 is formed through the inner wall of the feeding pipe 4. There are several dust suction holes 41, which are arranged equidistantly in the circumferential direction on the inner wall of the feeding pipe 4. A conical ton bag knife 42 is installed at the bottom of the inner cavity of the feeding pipe 4. The blade of the conical ton bag knife 42 faces upward and is used to break the falling ton bag materials so that the materials fall into the eight-cone silo 5. The left and right side walls of the feeding pipe 4 are provided with a first dust removal installation port 43, and the first dust removal installation port 43 is connected to a first bag dust collector 44.

[0028] Furthermore, the feeding pipe 4 is in the shape of a circular tube with a hollow interior, and the side wall of the feeding pipe 4 is a double-walled. There is a gap between the double-walled walls of the feeding pipe 4 to form a dust suction channel, and the dust suction channel is connected to the dust suction hole 41 and the first dust removal installation port 43. By setting the feeding pipe 4 to have a double wall, dust is generated in the process of the material entering the eight-cone silo 5 from the feeding pipe 4. The dust enters the dust suction channel from the dust suction hole 41 and enters the first bag dust collector 44 from the first dust removal installation port 43, thereby achieving the effect of removing the dust generated by the material feeding.

[0029] Furthermore, a discharge pipe 51 is connected to the bottom of the eight-cone silo 5, and a pneumatic butterfly valve 52 is installed in the middle of the discharge pipe 51. There are eight pneumatic butterfly valves 52, which respectively control the interception of materials in the eight discharge pipes 51. The eight discharge pipes 51 can discharge materials at the same time or individually. The front and rear side walls of the eight-cone silo 5 are penetrated with a second dust removal installation port 53, and the second dust removal installation port 53 is connected to a second bag dust collector 58. The material falling in the eight-cone silo 5 causes dust, and the dust is discharged from the first dust removal port 53. The second dust removal installation port 53 leads to the second bag dust collector 58, so as to achieve the effect of dust removal of the dust generated by the material discharge, and prevent the dust from floating and polluting the working environment. A stirring shaft 54 ​​is installed inside the eight-cone silo 5, and a V-shaped stirring rod 55 is connected to the outer wall of the stirring shaft 54. Bearings 56 are installed between the left and right ends of the stirring shaft 54 ​​and the side walls of the eight-cone silo 5. One side of the stirring shaft 54 ​​passes through the side wall of the eight-cone silo 5 and is connected to a drive motor 57, and the shaft end of the drive motor 57 is connected to the stirring shaft 54.

[0030] Furthermore, there are two stirring shafts 54, which are rotatably connected to the eight-cone silo 5 via bearings 56, and are driven to rotate by a driving motor 57. The V-shaped stirring rod 55 is composed of a round rod and a V-shaped block welded together. There are several V-shaped stirring rods 55, and four are arranged in a group at equal intervals in the circumferential direction on the outer wall of the stirring shaft 54. When the stirring shaft 54 ​​rotates, it drives the V-shaped stirring rod 55 to rotate. The rotation of the V-shaped stirring rod 55 breaks up the material in the eight-cone silo 5 to prevent the material from forming an arch bridge that affects the discharge of the material.

[0031] Furthermore, a feeding port 61 is provided on the crucible mouth sealing platform 6, and the number of the feeding ports 61 and the feeding pipes 51 are both eight, corresponding to the eight crucibles 8 placed on the vibration platform 7. When the eight-cone silo 5 descends, the eight feeding pipes 51 are respectively connected with the eight crucibles 8 to realize multi-station efficient filling, which greatly speeds up the working efficiency of filling the crucible 8. The bottom of the feeding pipe 51 is connected with the crucible mouth sealing platform 6, and the feeding pipe 51 is connected with the feeding port 61. When the lifting frame 111 drives the eight-cone silo 5 to move downward, the eight-cone silo 5 drives the crucible mouth sealing platform 6 to move downward and connect with the crucible 8 through the feeding pipe 51. The sealing plate of the crucible 8 mouth is pressed on the upper surface of the crucible 8. On the one hand, it is used to squeeze the crucible 8 to stably receive the material on the vibration platform 7, and on the other hand, the crucible 8 is sealed to prevent powder particles from floating upward during the falling process of the material.

[0032] Furthermore, a base 71 is provided under the vibration platform 7, and a vibration telescopic rod 72 is installed on the upper surface of the base 71. The bottom of the vibration telescopic rod 72 is connected to the base 71, and the top of the vibration telescopic rod 72 is connected to the vibration platform 7. There are eight crucibles 8, which correspond to the positions of the discharge port 61. During the process of receiving the material in the crucible 8, the vibration telescopic rod 72 is frequently extended and retracted to drive the vibration platform 7 to vibrate, and the vibration platform 7 drives the crucible 8 to vibrate, so that the material inside the crucible 8 is vibrated and compacted, thereby increasing the filling rate of the material in the crucible 8.

[0033] The method of using the present embodiment is as follows: when the user actually uses the semi-automatic multi-station crucible filling machine 8 to fill the crucible 8 with graphite, firstly, the graphite powder ton bag material is put into the feeding pipe 4 through the hanging hoist or the workshop crane, and the ton bag material falls and presses on the blade of the conical ton bag knife 42, and the conical ton bag knife 42 breaks the ton bag material, so that the material begins to fall, and the material powder enters the dust suction channel from the dust suction hole 41, flows in the dust suction channel, and finally enters the first bag dust collector from the first dust removal installation port 43. 44, the material falls into the eight-cone silo 5. When the eight-cone silo 5 is about to be filled, the staff uses a forklift and a pallet to deliver the crucible 8 to the vicinity of the crucible 8 loading machine, and then puts the eight crucibles 8 on the vibrating platform 7, and keeps the position of the crucible 8 aligned with the position of the discharge port 61, and then controls the hydraulic telescopic rod 112 to retract with the help of the hydraulic system through the power distribution cabinet 9, and the hydraulic telescopic rod 112 pulls the lifting frame 111 downward, and the lifting frame 111 drives the vertical rod 114 to slide downward in the middle of the guide block 115, and the lifting frame 111 is lifted and guided, and at the same time, the lifting frame 111 drives the eight-cone silo 5 to move downward, and the eight-cone silo 5 drives the discharge pipe 51 and the crucible mouth sealing platform 6 to move downward until the crucible mouth sealing platform 6 is pressed on the upper surface of the crucible 8, which is used to squeeze the crucible 8 on the vibration platform 7 to stably receive the material, and on the other hand, the crucible 8 is sealed, and then the driving motor 57 is turned on, the driving motor 57 drives the stirring shaft 54 ​​to rotate, and the stirring shaft 54 ​​drives the V-shaped stirring rod 55 to rotate, and the V-shaped stirring rod 55 breaks up the material. , to prevent the material from forming an arch bridge that affects the discharge of the material, and then the pneumatic butterfly valve 52 is opened to connect the inner cavity of the eight-cone silo 5 with the inner cavity of the crucible 8 through the discharge pipe 51, and the material falls into the crucible 8. At the same time, the vibrating telescopic rod 72 is frequently extended and retracted to drive the vibrating platform 7 to vibrate, and the vibrating platform 7 drives the crucible 8 to vibrate, so that the material inside the crucible 8 is vibrated and compacted, and the falling material causes dust, and the dust enters the second bag dust collector 58 from the second dust removal installation port 53. After the material in the crucible 8 is full, the full crucible 8 is forked out by a forklift.
