Description

Technical Field

[0001] The utility model relates to a sagger, in particular to a graphite sagger, and belongs to the technical field of graphite preparation. Background Art

[0002] Calcination is a common method for forming powder materials. For example, the production of lithium-ion cathode and anode materials requires calcination. The powdered raw materials for the cathode and anode are placed in a designated container (graphite sagger), which is then placed on the kiln's external line. This line continuously feeds the sagger into the kiln cavity for sintering.

[0003] In the prior art, there is a graphite sagger disclosed in announcement number CN218380494U. The contact area between the graphite sagger and the external air is increased, so that the temperature inside and outside the graphite sagger is kept uniform, and thermal stress concentration on the bottom plate or side plates due to internal heat accumulation does not occur, thus preventing the graphite sagger from breaking due to thermal stress. Moreover, since heat does not accumulate in the graphite sagger, the graphite sagger will not oxidize with the air due to excessive temperature inside the graphite sagger during long-term use. This prevents chemical reactions between the graphite sagger and the internal workpiece, and can increase the service life of the graphite sagger. However, in order to increase the calcination capacity, manufacturers now generally increase the width, height, and length of the kiln body, as well as the number of saggers entering the kiln at the same time. Kilns have gradually developed from single-layer four-row to single-layer six-row, double-layer eight-row, and so on. With the increase in the number of kiln rows, kiln blockage often occurs, which seriously affects product quality and kiln output. Although the current graphite saggers can prevent chemical reactions between the graphite saggers and internal workpieces and increase the service life of the graphite saggers, they do not solve the problem that the saggers in the same row are not uniform after running in the kiln cavity, and in serious cases, the kiln is blocked.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, a graphite sagger comprises a sagger body 1 and a docking mechanism 2, wherein a docking mechanism 2 is provided between adjacent sagger bodies 1, and the docking mechanism 2 comprises two groups of telescopic rod assemblies 3 and two groups of hook assemblies 4, the telescopic rod assemblies 3 are respectively connected to both sides of the sagger body 1, and the other end of the telescopic rod assembly 3 is connected to the hook assembly 4, and the two groups of hook assemblies 4 are docked together, and a plurality of sagger bodies 1 can be hooked and combined with each other through the provided docking mechanism 2, and the sagger bodies 1 in the same row are hooked with each other in the horizontal direction before entering the furnace, so that the sagger bodies 1 in the same row can achieve the effect of being flush when out of the furnace, and the telescopic rod assembly 3 provided can be adjusted in length to adaptively adjust the distance between two adjacent sagger bodies 1 after being hooked;

[0031] The telescopic rod assembly 3 includes a threaded rod 31, an outer rod 32, and a rotating sleeve 33. The threaded rod 31 is movably inserted into the outer rod 32. The rotating sleeve 33 is rotatably connected to one end of the outer rod 32. The rotating sleeve 33 is threadedly engaged with the rod body of the threaded rod 31. The threaded rod 31 can be moved and adjusted by rotating the rotating sleeve 33, that is, the overall length of the telescopic rod assembly 3 can be adjusted.

[0032] The two relative hook components 4 are arranged in a centrally symmetrical shape, and each hook component 4 is provided with a hook body inclined surface 41 on both sides. When the two hook components 4 are docked together, the docking can be achieved by vertically docking up and down. In addition, the provided hook body inclined surface 41 can facilitate the docking of the two hook components 4 together to achieve aligned hooking.

[0033] Example 2

[0034] Improvements based on Example 1:

[0035] like Figures 1 to 6 As shown, a square limit groove 34 is provided in the rod body of the threaded rod 31 of the telescopic rod assembly 3, an insertion cavity 38 is provided in the rod body of the outer rod 32, and a square limit plug 39 is provided in the insertion cavity 38. One end of the square limit plug 39 is fixedly connected to the end face of the insertion cavity 38, and the other end of the square limit plug 39 is inserted in the square limit groove 34, so that the threaded rod 31 can only be telescopically adjusted in the insertion cavity 38 through the limiting docking effect of the square limit plug 39 and the square limit groove 34, that is, the threaded rod 31 can be prevented from rotating when the rotating sleeve 33 is rotated.

[0036] Furthermore, an annular retaining ring 35 is integrally connected to the open end of the rod body of the outer rod 32, and an annular retaining groove 310 is opened on the inner wall of the rotating sleeve 33, and the annular retaining groove 310 is movably clamped on the annular retaining ring 35, so that the rotating sleeve 33 and the outer rod 32 can be combined and connected together through the limiting clamping connection between the annular retaining groove 310 and the annular retaining ring 35, so that the rotating sleeve 33 can be rotated relative to the outer rod 32.

[0037] Furthermore, an internal thread ring 311 is provided in the tube of the rotating sleeve 33, and the internal thread ring 311 is fixedly connected to the inner wall of the rotating sleeve 33 in a stepped manner, and the internal thread ring 311 is threadedly engaged with the rod body of the threaded rod 31, so that when the rotating sleeve 33 is rotated, the threaded rod 31 can be driven to move by the threaded engagement action, and the threaded rod 31 can be extended or retracted by rotating the sleeve 33 forward or reverse, so that the threaded rod 31 can be moved and adjusted conveniently and flexibly.

[0038] Furthermore, a positioning sleeve 36 is integrally connected to one side of the rotating sleeve 33. The positioning sleeve 36 is movably sleeved on the rod body of the outer rod 32, and a positioning bolt 37 is connected to the tube wall thread of the positioning sleeve 36. When the positioning bolt 37 is screwed, the front end of the positioning bolt 37 can be pressed against the rod body of the outer rod 32. The positioning sleeve 36 and the outer rod 32 can be fixed together through the action of friction, that is, the positioning sleeve 36 can be prevented from rotating randomly, so as to ensure that the length of the telescopic rod assembly 3 is fixed after adjustment.

[0039] like Figure 1 、 Figure 3 、 Figure 7 and Figure 8 As shown, the outer side hook body of the hook component 4 is provided with a docking positioning groove 42, and the inner side hook body of the hook component 4 is embedded with a docking positioning steel ball 43, and the inner and outer side surfaces of the two hook components 4 are aligned and docked together, so that the two hook components 4 form a hook-like connection with each other, and when docking, the inner side surface of one hook component 4 fits with the outer side surface of the other hook component 4, so that the docking positioning steel ball 43 can be stuck in the docking positioning groove 42, that is, the docking position can be further fixed.

[0040] Furthermore, a steel ball movable cavity 44 is opened on the inner side hook body of the hook component 4, and the docking positioning steel ball 43 is movably placed in the steel ball movable cavity 44. A compression spring 45 is also provided in the steel ball movable cavity 44, and the compression spring 45 is against the bottom of the docking positioning steel ball 43. When the two hook components 4 are docked, the docking positioning steel ball 43 can move appropriately in the steel ball movable cavity 44, thereby ensuring that it can be movably placed in the docking positioning groove 42 during docking.

[0041] Furthermore, a limiting baffle 5 is fixedly connected between the telescopic rod assembly 3 and the hook assembly 4. When the two hook assemblies 4 are docked in an upward and downward offset state, when the hook assembly 4 is against the limiting baffle 5, the upper hook assembly 4 can be moved vertically downward to ensure accurate alignment and docking.

[0042] Working principle: multiple sagger bodies 1 are hooked and combined together through the provided docking mechanism 2, and the sagger bodies 1 in the same row are hooked with each other in the horizontal direction before entering the furnace. When two hook components 4 are docked together, the docking is achieved through the upper and lower docking in the vertical direction, so that the sagger bodies 1 in the same row can achieve the effect of being flush when out of the furnace, and the provided telescopic rod component 3 can be adjusted in length. By rotating the rotating sleeve 33, the threaded rod 31 is driven to perform telescopic movement adjustment, that is, the overall length of the telescopic rod component 3 can be adjusted, so that the distance between two adjacent sagger bodies 1 after being hooked can be adaptively adjusted, and the provided hook body inclined surface 41 can facilitate the docking of the two hook components 4 together to achieve alignment and hooking.
