Technical Field

[0001] The utility model relates to the technical field of crucibles, in particular to a crucible used for producing lithium battery electrode materials. Background Art

[0002] The crucible is made of natural flake graphite as the main raw material and plastic refractory clay or carbon as a binder. It has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance, and long service life. During high-temperature use, the thermal expansion coefficient is small, and it has a certain resistance to strain in rapid cooling and rapid heating. It has strong corrosion resistance to acidic and alkaline solutions, has excellent chemical stability, and does not participate in any chemical reaction during the smelting process. The inner wall of the graphite crucible is smooth, and the molten metal liquid is not easy to leak and adhere to the inner wall of the crucible, so that the metal liquid has good fluidity and castability, and is suitable for casting and molding in various molds.

[0003] When using the crucibles produced from existing lithium battery electrode materials, workers are usually required to manually add materials to the inside of the crucible, manually compact the materials, then cover the top of the crucible, and then put the crucible into a container for burning, thereby refining the materials inside the crucible.

[0004] However, most of the existing crucibles for producing lithium battery electrode materials directly place the top cover on the crucible, and the top cover cannot be fixed in position. As a result, when the material inside the crucible is heated and reacts, the top cover is easily lifted up, causing the internal material to leak, thereby causing damage to the crucible and accidental injury to the operator. Summary of the invention

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a crucible for producing lithium battery electrode materials, aiming to improve the problem that most of the existing crucibles cannot firmly fix the top cover well.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crucible for the production of lithium battery electrode materials, comprising a crucible body, a top cover slidably connected to the inside of the crucible body, a rotating rod rotatably connected to the inside of the top cover, a knob fixedly connected to one end of the rotating rod, a turntable fixedly connected to the other end of the rotating rod, a limiting groove is provided inside the turntable, a movable plate is slidably connected to the inside of the turntable, the outer wall of the movable plate is slidably connected to the inside of the limiting groove, a slider is rotatably connected to the outer wall of the movable plate, a limiting assembly is arranged inside the slider, an insertion rod is fixedly connected to the outer wall of the slider, and the outer wall of the insertion rod is slidably connected to the inside of the crucible body.

[0007] Furthermore, the limiting assembly includes a slide rail, an outer wall of the slide rail is slidably connected to the inside of the sliding block, and the outer wall of the slide rail is fixedly connected to the inside of the top cover.

[0008] Furthermore, a left fixing ring is provided on the outer wall of the crucible body, and a right fixing ring is slidably connected to the outer wall of the left fixing ring.

[0009] Furthermore, the outer wall of the left fixed ring is fixedly connected with a connecting seat, and the interior of the connecting seat is rotatably connected with a rotating shaft.

[0010] Furthermore, the outer wall of the rotating shaft is fixedly connected to the inside of the right fixing ring, and a positioning hole is opened inside the right fixing ring.

[0011] Furthermore, threaded rods are threadedly connected inside the left fixing ring and the right fixing ring.

[0012] Furthermore, one end of the threaded rod is fixedly connected to a toggle, and the other end of the threaded rod is rotatably connected to an arc plate.

[0013] Furthermore, outer walls of the left fixing ring and the right fixing ring are fixedly connected with connecting plates, and internal threads of the connecting plates are connected with fixing bolts.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, firstly, the turntable is driven to push the movable plate by rotating the knob, and then the slider pushes the insertion rod until the insertion rod is completely fixed inside the crucible body, thereby achieving the effect of firmly fixing the top cover inside the crucible, solving the problem that most of the existing crucibles cannot firmly fix the top cover well, improving the stability of the crucible, and ensuring the normal use of the crucible.

[0016] 2.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a crucible for producing lithium battery electrode materials, comprising a crucible body 1, a top cover 2 is slidably connected inside the crucible body 1, a rotating rod 3 is rotatably connected inside the top cover 2, a knob 4 is fixedly connected to one end of the rotating rod 3, a turntable 5 is fixedly connected to the other end of the rotating rod 3, a limiting groove 6 is provided inside the turntable 5, a movable plate 7 is slidably connected inside the turntable 5, the outer wall of the movable plate 7 is slidably connected to the inside of the limiting groove 6, a slider 8 is rotatably connected to the outer wall of the movable plate 7, a limiting assembly is arranged inside the slider 8, an insertion rod 10 is fixedly connected to the outer wall of the slider 8, and the outer wall of the insertion rod 10 is slidably connected to the inside of the crucible body 1; the limiting assembly comprises a slide rail 9, the outer wall of the slide rail 9 is slidably connected to the inside of the slider 8, and the outer wall of the slide rail 9 is fixedly connected to the inside of the top cover 2;

[0024] Specifically, when the top cover 2 needs to be firmly fixed, the knob 4 is turned to rotate the rotating rod 3. The rotating rod 3 is connected to the turntable 5, so the rotation of the rotating rod 3 will drive the turntable 5 to rotate. The interior of the turntable 5 is designed with a slideway, and the movable plate 7 can slide along this slideway. When the turntable 5 rotates, the movable plate 7 will move accordingly and push the slider 8. The slider 8 can fit tightly with the inner wall of the crucible body 1, so when the slider 8 is pushed, it will move upward along the inner wall of the crucible body 1. With the continuous push of the movable plate 7, the slider 8 will eventually drive the insertion rod 10 to be completely inserted into the top of the crucible body 1, thereby achieving a firm fixation of the top cover 2. This is not only simple and easy, but also very strong, which can effectively improve the stability of the crucible and ensure the normal use of the crucible in a high temperature environment.

[0025] Reference Figure 1 and Figure 3 The outer wall of the crucible body 1 is provided with a left fixing ring 11, and the outer wall of the left fixing ring 11 is slidably connected to the right fixing ring 12; the outer wall of the left fixing ring 11 is fixedly connected to a connecting seat 13, and the interior of the connecting seat 13 is rotatably connected to a rotating shaft 14; the outer wall of the rotating shaft 14 is fixedly connected to the interior of the right fixing ring 12, and a positioning hole 15 is opened inside the right fixing ring 12; the interiors of the left fixing ring 11 and the right fixing ring 12 are both threadedly connected to a threaded rod 17; one end of the threaded rod 17 is fixedly connected to a twisting knob 18, and the other end of the threaded rod 17 is rotatably connected to an arc plate 16; the outer walls of the left fixing ring 11 and the right fixing ring 12 are both fixedly connected to a connecting plate 19, and the interior of the connecting plate 19 is threadedly connected to a fixing bolt 20;

[0026] Specifically, when the crucible needs to be taken out, first, the left fixing ring 11 and the right fixing ring 12 are sleeved on the outer wall of the crucible body 1. Then, by turning the fixing bolt 20, the two connecting plates 19 are contracted and retracted inward. Next, by turning the knob 18, the threaded rod 17 is driven to rotate. As the threaded rod 17 rotates, the arc plate 16 is fixed on the surface of the crucible body 1. This process ensures the safe fixation of the crucible body 1 for the removal operation. When the crucible needs to be taken out, just align the clamp with the inside of the positioning hole 15 and then hook it out easily. This makes the process of taking out the crucible more convenient and efficient, improves the practicality of the crucible, and simplifies the operation process of the crucible. Through this convenient and practical removal device, the crucible removal operation can be easily performed, thereby improving work efficiency and reducing the complexity of operation, further promoting the wide application and convenience of use of the crucible.

[0027] When the top cover 2 needs to be firmly fixed, the rotating rod 3 is driven to rotate by turning the knob 4, so that the rotating rod 3 can drive the rotating disk 5 to rotate, and then the movable plate 7 slides inside the rotating disk 5, so that the rotating disk 5 can drive the movable plate 7 to push the slider 8 while rotating, until the insertion rod 10 is completely inserted into the crucible body 1, thereby achieving the effect of firmly fixing the top cover 2 inside the crucible, improving the stability of the crucible and ensuring the normal use of the crucible. When the crucible needs to be taken out, the left fixing ring 11 and the right fixing ring 12 are sleeved on the outer wall of the crucible body 1, and the fixing bolts 20 are turned to close the two connecting plates 19, and then the threaded rod 17 is driven to rotate by turning the knob 18 until the arc plate 16 is fixed to the surface of the crucible body 1. When the crucible body 1 is taken out, the clamp only needs to be aligned with the inside of the positioning hole 15 to hook it out, thereby achieving the effect of facilitating the removal of the crucible, improving the practicality of the crucible and facilitating the use of the crucible.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
