Abstract
Description
Technical Field
[0001] This utility model belongs to the field of graphite sagger sealing technology, and in particular relates to a graphite sagger sintering sealing and protection mechanism. Background Technology
[0002] Graphite saggers are high-temperature resistant containers made of graphite material, widely used in the high-temperature sintering processes of lithium battery cathode materials (such as lithium iron phosphate, ternary materials, etc.), anode materials, ceramic powders, rare earth materials, phosphors, magnetic materials, cemented carbide, powder metallurgy products, etc.
[0003] Currently, the opening of the graphite sagger is sealed by two layers of plates. However, when the material is sprayed, the nozzles are prone to clogging the pores of the upper body, which prevents the subsequent gas from being discharged in time and affects the normal performance of the graphite sagger.
[0004] To address the aforementioned issues, this application proposes a graphite saggar sintering sealing and protection mechanism. Utility Model Content
[0005] The purpose of this invention is to provide a graphite saggar sintering sealing and protection mechanism, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a graphite saggar sintering sealing and protection mechanism, including a saggar body, a cover body, and a sealing plate. The cover body has air holes inside, and the left and right sides of the cover body have protruding plates that connect with the side grooves at the upper end of the saggar body.
[0008] The cover has oblique spray holes along the front-to-back direction inside, and the spray holes are arranged at equal intervals along the left-to-right direction. A first guide plate and a second guide plate extend obliquely from both sides of the spray holes, and the oblique directions of the left and right areas of the cover plate are opposite. An arc-shaped plate extends from the upper end of the first guide plate, and the spray holes face the inside of the arc-shaped plate.
[0009] Preferably, the inner wall of the second guide plate is beveled, with the same bevel direction as the nozzle, and an opening is formed between the upper end face of the second guide plate and the lower end face of the arc-shaped plate.
[0010] Preferably, a storage area is formed between the outer wall of the first guide plate and the outer wall of the second guide plate.
[0011] Preferably, the arc-shaped plate has a semi-circular structure, forming a gas storage area inside.
[0012] Preferably, the lower end of the sealing plate has a conical guide plate protruding from it, located between adjacent spray holes, with the cone facing downwards.
[0013] Preferably, an upwardly protruding frame is fixed above the sealing plate near the outer ring area, and the front and rear inner sides are fixedly connected to the first guide plate.
[0014] Preferably, the convex plate is fixedly installed on the outside of the frame.
[0015] This utility model has the following beneficial effects:
[0016] This invention replaces the traditional vertical spray holes with oblique spray holes inside the sealing plate. Combined with the guidance of the first guide plate and the arc plate, the sprayed material is intercepted and stored between the outer walls of the first guide plate and the second guide plate. This effectively prevents the sprayed material from clogging the air holes, thereby maintaining the stable performance of the graphite sagger during long-term sintering operations.
[0017] This invention utilizes the arc-shaped guiding structure of the arc plate to directly intercept the gas entering the vent from the outside and concentrate it in the storage area. The thrust generated during internal material spraying and the external spray pressure of the gas drive the gas entering from the outside to be discharged through the vent, effectively preventing external gas from directly entering the pot and ensuring the sintering quality of the negative electrode material.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0033] Please see Figure 1-4 As shown, this utility model is a graphite saggar sintering sealing and protection mechanism, including a saggar body 100, a cover body 200 and a sealing plate 300. The cover body 200 has an air hole 201 inside, and the left and right sides of the cover body 200 have protruding plates 301 that connect with the side grooves 101 at the upper end of the saggar body 100.
[0034] The cover 200 has oblique spray holes 320 in the front-to-back direction. The long groove structure replaces the traditional circular vertical hole to increase the spray area of the spray material and prevent some of the spray material from being intercepted by the sealing plate 300. The spray holes 320 are arranged at equal intervals in the left-to-right direction. The first guide plate 321 and the second guide plate 323 extend obliquely from both sides of the spray holes 320, with the same orientation as the spray holes 320. The oblique orientations of the two areas on the left and right sides of the sealing plate 300 are opposite. The upper end of the first guide plate 321 extends into an arc plate 322. The spray holes 320 face the opening at the lower end of the arc plate 322. The upper edge of the arc plate 322 is adjacent to the lower surface of the cover 200.
[0035] Furthermore, the inner wall of the second guide plate 323 is beveled, which is the same as the bevel of the nozzle 320. It is combined with the first guide plate 321 to form an oblique channel. An opening is formed between the upper end face of the second guide plate 323 and the lower end face of the arc plate 322. When the sprayed material passes through the oblique channel, it is guided by the inner edge of the arc plate 322 and passes through the opening to be stored between the outer wall of the first guide plate 321 and the outer wall of the first guide plate 321 to form a storage area.
[0036] Furthermore, the arc plate 322 has a semi-circular structure, forming a gas storage area inside. Some gas directly enters the storage area and is discharged outward through the vent 201. The temporary storage of some gas intercepts the gas entering from the outside, thereby creating a sealing effect.
[0037] Furthermore, the lower end of the sealing plate 300 has a conical guide plate 330 protruding from it, located between adjacent spray holes 320, with the cone facing downwards. When the spray material is sprayed upwards, it is guided to the spray hole 320 by the conical guide plate 330.
[0038] Furthermore, an upwardly protruding frame 310 is fixed above the sealing plate 300 near the outer ring area, and the front and rear inner sides are fixedly connected to the first guide plate 321 to seal the openings formed at both ends of the first guide plate 321 and the second guide plate 323, so that the spraying is carried out within a fixed area.
[0039] Furthermore, the protruding plate 301 is fixedly installed on the outside of the frame 310.
[0040] It is understood that this utility model, by changing the direction of the spray and forming a pre-interception, stores the material in a fixed area and leaves some gas at the opening. With this arrangement, it can prevent the spray from clogging the upper holes and affecting the subsequent gas ejection, and also prevent external gas from directly entering the interior and affecting the use of the graphite sagger.
[0041] A specific application of the operation process of this embodiment is as follows: During use, the material sprayed into the bowl 100 is obliquely sprayed out along the spray hole 320, the first guide plate 321, and the second guide plate 323, and then falls back into the storage area between the outer wall of the second guide plate 323 and the outer wall of the first guide plate 321 under the guidance of the arc plate 322. At the same time, part of the sprayed gas enters the storage area, and part is temporarily stored inside the arc plate 322. Further, external gas enters the buffer area through the air hole 201. The gas temporarily stored in the arc plate 322 blocks the external gas, preventing it from passing through the spray hole 320 and entering the interior of the bowl 100, thereby forming a sealing effect. Furthermore, when the bowl 100 is sprayed again, the material is still gathered in the storage area, while the gas pushes the temporarily stored gas and the blocked gas, causing it to pass through the air hole 201 and be discharged outward, achieving the effect of self-cleaning external gas.
