Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crucibles, in particular to a new type of crucible. Background Art
[0002] Under the background of the current country's strong development of green energy and strengthening of new energy, lithium-ion batteries have emerged suddenly and developed rapidly. The production capacity of the positive and negative electrodes has increased linearly. However, the new production line has a long cycle and many procedures. If you want to put it into production as soon as possible, you currently have to use the existing furnace type for transformation. This results in a situation where the existing crucibles do not match the original furnace type. Moreover, in the newly built furnace type, through the transformation of this technology, the output can also be greatly increased and the cost can be reduced. At present, there are only two specifications of porous crucibles on the market, namely Φ850 and Φ960 round crucibles, which have the following disadvantages:
[0003] 1. The design of 1 large hole plus 9 small holes in the existing crucible wastes space. It not only has complex mechanical processing, is prone to processing waste and defective products, but also has limited loading capacity;
[0004] 2. At the same time, when the hole body of the crucible is damaged, the whole crucible is scrapped and cannot be repaired, increasing the use cost. Summary of the Utility Model
[0005] The main purpose of the utility model is to provide a new type of crucible.
[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:
[0007] A new type of crucible, including an outer crucible and an inner crucible. A connecting screw groove is processed at the bottom inside the outer crucible, and a connecting stud is processed at the bottom of the inner crucible;
[0008] A support block is detachably pressed between the outer crucible and the inner crucible.
[0009] Preferably, limiting holes are symmetrically opened in the inner wall of the support block. A pin hole is aligned on one side of the limiting hole, and the pin hole penetrates through the inner walls of the outer crucible and the inner crucible.
[0010] Preferably, limiting pins are inserted into both the pin hole and the limiting hole, and an inner hexagon connection thread head is integrally formed at the end of the limiting pin.
[0011] Preferably, the heights of the outer crucible and the inner crucible are 1000 mm, the inner wall thickness of the outer crucible is 70 mm, and the inner wall thickness of the inner crucible is 65 mm.
[0012] Preferably, the bottom plate thicknesses of both the outer crucible and the inner crucible are 50 mm.
[0013] Preferably, the total length of the limiting pin and the inner hexagon thread head is 120 mm.
[0014] The beneficial technical effects of the present utility model are as follows:
[0015] By designing a combined crucible, the present utility model has the following advantages:
[0016] Two crucibles with different diameters are combined and sleeved together through the threaded structure at the bottom, realizing detachable installation. This not only facilitates maintenance and replacement, avoids the drawback of scrapping the traditional integral structure crucible after the material hole is damaged, reduces the use cost of the crucible, but also improves the loading capacity compared with the traditional 9 small holes and 1 large hole integral crucible structure, thereby increasing the output of the graphitization process.

[0023] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. However, the embodiments of the present utility model are not limited thereto.
[0024] As Figures 1 - 4 shown, a new crucible provided in this embodiment includes an outer crucible 1 and an inner crucible 2. A connecting screw groove 6 is machined at the inner bottom of the outer crucible 1, and a connecting stud 5 is machined at the bottom of the inner crucible 2. The connecting screw groove 6 and the connecting stud 5 are threadedly connected in a matching manner, which is convenient for disassembly, replacement and maintenance; a support block 3 is detachably pressed between the outer crucible 1 and the inner crucible 2. The support block 3 is used to support the inner crucible 2 to be positioned on the inner wall of the outer crucible 1 so that it is in the central position in all directions.
[0025] The inner wall of the support block 3 is symmetrically provided with limit holes 9. One side of the limit hole 9 is aligned with a pin hole 4. The pin hole 4 penetrates through the inner walls of the outer crucible 1 and the inner crucible 2. The pin hole 4 has two sections of structures. One section is adapted for the entry and exit of the limit pin 8, and the other section is adapted for the connection of the inner hexagon threaded head 7.
[0026] Limit pins 8 are inserted into both the pin hole 4 and the limit hole 9. An inner hexagon connection threaded head is integrally formed at the end of the limit pin 8.
[0027] The heights of the outer crucible 1 and the inner crucible 2 are 1000 mm. The inner wall thickness of the outer crucible 1 is 70 mm, and the inner wall thickness of the inner crucible 2 is 65 mm.
[0028] The bottom plate thicknesses of both the outer crucible 1 and the inner crucible 2 are 50 mm.
[0029] The total length of the limit pin 8 and the inner hexagon threaded head 7 is 120 mm.
[0030] The working principle of this device: When this device is specifically used, the inner crucible 2 is screwed and installed with the connection screw groove 6 at the inner bottom of the outer crucible 1 through the connection stud 5 at the bottom. Then, a group of limit pins 8 are inserted into the pin hole 4 from the outside. After the limit pins 8 pass through the pin hole 4, they are inserted into the limit hole 9 on one side of the support block 3. Another group of limit pins 8 are inserted into the pin hole 4 from inside the inner crucible 2. After the limit pins 8 pass through the pin hole 4, they are inserted into the limit hole 9 on the other side of the support block 3. The end of the limit pin 8 is connected with an inner hexagon threaded head 7, which is screwed and connected with the thread in the inner wall of the pin hole 4 to lock the support block 3, thereby achieving the purpose of fixedly supporting the inner crucible 2 and the outer crucible 1.
[0031] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent replacements or changes, all belong to the protection scope of the present utility model.
