Description

Technical Field

[0001] The utility model relates to the technical field of crucible unloading, in particular to a clamping device and an unloading device of a crucible type graphitization furnace. Background Art

[0002] When the lithium battery graphite negative electrode material adopts a crucible-type graphitization furnace, the carbonized powder material is loaded into the crucible and then placed in the crucible-type graphitization furnace for graphitization treatment. After the graphitization is completed, the finished product is cooled to a certain temperature. Generally, it is manually tied to the outer wall of the crucible with a steel wire rope and hoisted out of the crucible-type graphitization furnace by a crane. Since the temperature of the crucible is high when it is taken out of the furnace, it is very dangerous to manually lasso in the crucible-type graphitization furnace, and the high-temperature crucible is inconvenient to carry, and the efficiency of taking out of the furnace is low. At the same time, the force-bearing surface of the steel wire rope is small and has a certain degree of flexibility. The crucible is prone to collision and slippage during lifting, resulting in the damage of the crucible and material leakage, which increases the cost of the enterprise. At present, in the carbon material industry, the formed roasted blanks are also cooled down after graphitization treatment in the crucible-type graphitization furnace, and it is difficult to carry them manually.

[0003] In addition to the existing technology, the crucible can also be lifted by other lifting equipment, but the lifting process is mostly to clamp the top of the crucible, which is easy to cause the crucible to break or slip; other methods that use plug plates and support plates to clamp are to wrap the outside of the graphite product with a plug plate, insert the support rod into the bottom of the crucible and then lift it. Since the crucible and the materials contained in it weigh hundreds of kilograms, it is difficult to insert the support plate directly into the bottom of the crucible. If the insertion direction is not accurate, the crucible will be damaged or tipped over, which will cause cost waste. Utility Model Content

[0034] In a preferred embodiment of the present utility model, based on the above problems existing in the prior art, a furnace discharge device for a crucible type graphitization furnace is provided. Figure 1 , Figure 2 and Figure 3 As shown, including:

[0043] A travel drive motor 16 is provided to drive the gantry 1 to travel along the length direction of the outer track to adjust the position of the gantry 1 on the outer track. Figure 1 As shown, the sliding direction of the horizontal slider 11 is X, and the lifting direction of the lifting device 2 is Y, then the length direction of the outer track is perpendicular to the XY plane, that is, the Z-axis direction in the three-dimensional coordinate system.

[0044] A horizontal slide rail 12 and a horizontal slider 11 are provided in the gantry 1. The positions of the connected lifting device 2 and the clamping device 3 can be adjusted in the horizontal direction by sliding the horizontal slider 11 in the horizontal slide rail 12, and the clamping device 3 is moved to the crucible out-of-furnace position of the crucible-type graphitization furnace to clamp the crucible out of the furnace.

[0045] The above-mentioned furnace discharging device includes a clamping device 3 provided by the utility model, such as Figure 2 and Figure 3 Shown include:

[0046] A connecting plate 31, the upper surface of the connecting plate 31 is connected to the lifting device 2 through the connecting rod 21, and the lower surface of the connecting plate 31 is connected to the lifting rod 32 and the rotating rod 33;

[0047] A clamping part 300, a wall plate 310 of the clamping part 300 is connected to a connecting plate 31 through a lifting rod 32, and the clamping part 300 is clamped on the outer wall of the crucible of the crucible-type graphitization furnace;

[0048] The supporting plate 34 is connected to the bottom of the rotating rod 33. A rotating motor 35 is provided on the top of the rotating rod 33. When the clamping portion 300 clamps the crucible and is lifted by the lifting device 2, the rotating motor 35 drives the rotating rod 33 to drive the supporting plate 34 to rotate to the bottom of the clamped crucible to support the crucible.

[0049] The lifting device 2 in the clamping device 3 of this embodiment includes a plurality of lifting rails which are nested and connected in sequence, and the lifting rails include a first-stage lifting rail 22, a second-stage lifting rail 23 and a third-stage lifting rail 24 at the end;

[0050] The back of the first-stage lifting rail 22 is connected to the horizontal slider 11, the first-stage lifting rail 22 is provided with a second-stage lifting slider 25, the second-stage lifting slider 25 is connected to the top of the second-stage lifting rail 23, the second-stage lifting rail 23 is provided with a third-stage lifting slider 26, the third-stage lifting slider 26 is connected to the top of the third-stage lifting rail 24;

[0051] A lifting motor 27 is arranged at the top of the first-stage lifting rail 22, and is used to drive the second-stage lifting slide block 25 and the third-stage lifting slide block 26 to slide in the first-stage lifting rail 22 and the second-stage lifting rail 23 respectively. The lower part of the third-stage lifting rail 24 at the end is connected to the connecting plate 31 through the connecting rod 21, so as to lift and lower the connected clamping device 3;

[0052] A plurality of limit plates 28 are respectively arranged at the ends of the first-stage lifting rail 22 , the second-stage lifting rail 23 and the third-stage lifting rail 24 , and are respectively used to limit the second-stage lifting slider 25 , the third-stage lifting slider 26 and the connecting rod 21 .

[0053] Specifically, in the present embodiment, the multi-stage lifting rails in the lifting device 2 are nested and connected in sequence, a second-stage lifting slide block 25 is provided in the first-stage lifting slide rail 22 and connected to the top of the second-stage lifting slide rail 23, driving the second-stage lifting slide rail 23 to retract / extend in and out of the first-stage lifting slide rail 22 when lifting / lowering, a third-stage lifting slide block 26 is provided in the second-stage lifting slide rail 23 and connected to the top of the third-stage lifting slide rail 24, driving the third-stage lifting slide rail 24 to retract / extend in and out of the second-stage lifting slide rail 23 when lifting / lowering, and the end of the third-stage lifting slide rail 24 is connected to the clamping device 3 through a connecting rod 21, and the multi-stage lifting rails are gradually contracted and overlapped during lifting to lift the crucible clamping device 3, and are gradually extended during lowering to lower the crucible clamping device 3.

[0054] Furthermore, a clamping portion 300 for clamping the crucible is provided in the clamping device 3, which clamps the outer wall of the crucible rather than the top of the crucible, and is not likely to cause the crucible to be damaged or slipped. After the crucible is clamped to a certain height, the supporting plate 34 is rotated and inserted into the bottom of the crucible, thereby reducing the insertion resistance of the supporting plate 34 when the crucible is not lifted, and preventing the crucible from tilting and tipping due to the supporting plate 34 being directly inserted into the bottom of the crucible.

[0055] The supporting plate 34 is processed into a square structure to support the bottom of the crucible, increase the contact area with the crucible, and avoid the phenomenon of damage caused by uneven force when the crucible is lifted.

[0056] The clamping part 300 clamps the outer walls of both sides of the crucible, the middle wall plate 310 fits the back of the crucible, and the supporting plate 34 supports the bottom of the crucible. The three work together to reduce the problem of slipping and tipping of the crucible during lifting.

[0057] In a preferred embodiment of the present invention, the clamping portion 300 is as follows Figure 3 As shown, including:

[0058] A plurality of telescopic rods 320, each of which is symmetrically arranged on both sides of the wall plate 310, and the telescopic direction X is perpendicular to the lifting direction Y of the lifting device 2;

[0059] There are multiple driving rods 330 , each of which is connected to a corresponding telescopic rod 320 , and each driving rod 330 is mounted with a clamping plate 340 .

[0060] The clamping plate 340 is arc-shaped, the arc fits the outer surface of the crucible, and the curvature of the arc is consistent with the curvature of the outer surface of the crucible.

[0061] A diagonal support plate 350 is further provided between the driving rod 330 and the corresponding clamping plate 340 .

[0062] A plurality of telescopic rods 320 are disposed on each side of the wall panel 310 , and the telescopic rods 320 are arranged in sequence from top to bottom.

[0063] Specifically, in the present embodiment, there are two lifting rods 32 and they are symmetrical. The lower part of the lifting rod 32 is connected to the wall plate 310. A plurality of telescopic rods 320 extend from both sides of the wall plate 310, and the positions of the telescopic rods 320 on both sides are symmetrical. The telescopic rods 320 are connected to the driving rods 330. In the initial state, the spacing between the two corresponding clamping plates 340 is greater than the maximum outer diameter of the crucible. When clamping is required, the telescopic rods 320 contract inwardly and drive the corresponding clamping plates 340 to clamp on the outer wall of the crucible through the driving rods 330. An inclined support plate 350 is connected between each driving rod 330 and the clamping plate 340, and the inclined support plate 350 is connected to the outer wall of the clamping plate 340.

[0064] Furthermore, in order to improve the stability during clamping, we can widen the width of the clamping plate 340. In this case, multiple telescopic rods 320 and driving rods 330 are provided on each side. Then, one clamping plate 340 corresponds to two or even more driving rods 330, and a diagonal support plate 350 is connected between each driving rod 330 and the corresponding clamping plate 340.

[0065] The telescopic direction X of the telescopic rod 320 is perpendicular to the lifting direction Y of the lifting device 2. When the telescopic rod 320 contracts, it drives the driving rod 330 and the clamping plate 340 to press against the outer wall of the crucible. The inside of the clamping plate 340 is a block plate staggered splicing, and the reserved gap between the plates ensures that it has a certain curvature to form an arc, and the curvature of the arc is consistent with the curvature of the outer surface of the crucible. Under the action of the diagonal support plate 350, it is close to the outer wall of the crucible. The clamping plate 340 is made of a splicing plate, which can be flexed and stretched to wrap the outer wall of the crucible to improve the clamping force. On the contrary, when the telescopic rod 320 is extended, it drives the driving rod 330 and the clamping plate 340 to open and unload the crucible. The lower part of the rotating rod 330 is connected to the supporting plate 34. Generally, the supporting plate 34 rotates to both sides of the wall plate 310. When the crucible is taken out of the furnace, the clamping plate 340 first clamps the crucible and lifts it, and then the rotating supporting plate 34 rotates to the bottom of the crucible. The supporting plate 34 is a square or circular structure, or other structural shapes are also possible. Further, after the clamping plate 340 clamps the crucible, the crucible is clamped and lifted by the contraction and embracing of the driving rod 330 and the diagonal support plate 350 and the lifting action of the upper lifting device 2, and then the crucible is transported by sliding the slider of the gantry 1 and sliding on the outer track.

[0066] Compared with the prior art, the utility model has the following beneficial effects:

[0067] The interior of the clamping plate 340 is as follows Figure 4 As shown, the block plates are spliced ​​to form an arc, which can be opened and tightened under the push of the telescopic rod 320, and the fit with the crucible wall is higher, so as to improve the fixing effect on the crucible and prevent the crucible from slipping; the crucible is clamped by the side wall clamp and the bottom support. After the crucible is lifted to a certain height by the side wall clamp of the clamping plate 340, the rotating support plate 34 is inserted into the bottom of the crucible, making the insertion operation of the support plate 34 more labor-saving; during the lifting and transfer process, the bottom support plate 34 plays a load-bearing role, and the two sides The clamping plate 340 plays a gripping role to prevent the crucible from slipping and being damaged; the three-level vertical lifting slide rail in the lifting device 2 is matched with the horizontal slide rail 12 of the gantry 1, which makes it more flexible to remove the crucibles from different parts of the crucible-type graphitization furnace, realizes the free horizontal and vertical transportation of the crucible, and improves the efficiency of removing the furnace; the depth of the crucible-type graphitization furnace can generally reach 5 meters, and the vertical lifting device 2 is made into a telescopic and superimposed type to ensure the flexibility and safety of the lifting device 2 structure and save operating space. In addition, this clamping process is completed by the device, without manual handling, which improves the efficiency of removing the furnace and reduces the possibility of damage to the crucible.

[0068] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
