Abstract
The utility model discloses a crucible for high purity alumina roasting. The crucible comprises a crucible body and a crucible cover. The crucible body is in the shape of a cylinder with the bottom face sealed and the upper end open. The crucible is characterized by further comprising a connection body. The connection body is in the shape of a cylinder matched with the crucible and with two ends open. A step face is arranged on the inner wall at the lower end of the connection body, a step face is arranged on the outer wall of an opening in the upper end of the crucible body, the connection body is arranged at the upper end of the crucible body through the step face, a plurality of exhaust holes are formed in the upper edge of the connection body in the circumferential direction, a limit table protruding downwards is arranged on the bottom face of the crucible cover, a limit step is arranged at the top end of the connection body at the position corresponding to the limit table, and the crucible cover is matched with the top end of the connection body. The crucible is simple in structure and reasonable in design, the crucible cover is effectively prevented from creeping down and being broken by means of the limit table, and the crucible is safe to use. The exhaust holes are formed in the connection body, dust cannot enter the crucible body easily, and the alumina purity is improved.
Description
Technical field
The utility model relates to and belongs to high purity aluminium oxide process units technical field, particularly relates to a kind of splendid attire high purity aluminium oxide crucible that roasting is used in kiln.
Background technology
The crucible lid of the existing crucible for splendid attire high purity aluminium oxide is the disk of equal thickness, for guaranteeing crucible hardness, crucible body and crucible lid are made by quartz sand, very smooth, frictional force is very little, and this crucible covers in the process of using, and crucible lid side is subject to very little radial load and is just easy to landing, break crucible lid into pieces and even cause crucible vivo oxidation aluminium to be polluted, cause very large loss.For allowing air can free in and out crucible body, crucible lid is tiltedly placed on crucible body conventionally, and dust is just easy to drop in crucible body like this, causes aluminium oxide purity inadequate.
Utility model content
The purpose of this utility model is just to provide a kind of high purity aluminium oxide roasting crucible, and crucible lid is difficult for landing, has dustproof effect, can solve above-mentioned the deficiencies in the prior art part completely.
The purpose of this utility model realizes by following technical proposals:
A kind of high purity aluminium oxide roasting crucible, comprise crucible body and crucible lid, crucible body is the cylindrical shape of sealing bottom surface upper end open, it is characterized in that: also comprise connector, this connector is the cylindrical shape of the upper and lower opening that mates with crucible body, connector lower end inwall is provided with step surface, crucible body upper end open outer wall is to there being step surface, by step surface, connector is placed into crucible body upper end, on connector, along the circumferential direction offer some steam vents, the limiting stand of the oriented lower convexity in crucible lid bottom surface, connector top is to being provided with limited step by limiting stand, crucible lid coordinates with connector top.
As preferably, described limiting stand is cylinder.
As preferably, described limiting stand is round platform.
The beneficial effects of the utility model are: simple in structure, reasonable in design, limiting stand can effectively prevent that crucible from covering landing and smashing, and uses safety; On connector, offer steam vent, dust is difficult for entering into crucible body, improves aluminium oxide purity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment mono-;
Fig. 2 is the structural representation of the utility model embodiment bis-.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
Embodiment mono-
As shown in Figure 1, a kind of high purity aluminium oxide roasting crucible, comprise crucible body 1, connector 2 and crucible lid 3, crucible body 1 is the cylindrical shape of sealing bottom surface upper end open, described connector 2 is the cylindrical shape of the upper and lower opening that mates with crucible body 1, connector 2 lower end inwalls are provided with step surface, crucible body 1 upper end open outer wall is to there being step surface, by step surface, connector 2 is placed into crucible body 1 upper end, on connector 2, along the circumferential direction offer some steam vents 4, crucible covers the limiting stand 5 of the 3 oriented lower convexity in bottom surface, described limiting stand 5 is cylinder, connector 2 tops are to being provided with limited step 6 by limiting stand 5, crucible lid 3 coordinates with connector 2 upper end open.
During use, connector 2 is placed on crucible body 1 upper end by step surface, and then crucible lid 3 is placed on connector 2 upper ends, and by limiting stand 5, is undertaken spacingly, so crucible lid 3 is difficult for landing.The gas producing during aluminium oxide heating is discharged from the steam vent 4 of connector 2, and dust is difficult for falling in crucible body.
Embodiment bis-
Referring to Fig. 2, the difference of the present embodiment and embodiment mono-is, described limiting stand 5 is round platform, so crucible lid 3 is inclined-plane with the mating surface of connector 2, has the effect of automatic capturing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. a high purity aluminium oxide roasting crucible, comprise crucible body and crucible lid, crucible body is the cylindrical shape of sealing bottom surface upper end open, it is characterized in that: also comprise connector, this connector is the cylindrical shape of the upper and lower opening that mates with crucible body, connector lower end inwall is provided with step surface, crucible body upper end open outer wall is to there being step surface, by step surface, connector is placed into crucible body upper end, on connector, along the circumferential direction offer some steam vents, the limiting stand of the oriented lower convexity in crucible lid bottom surface, connector top is to being provided with limited step by limiting stand, crucible lid coordinates with connector top.
2. high purity aluminium oxide roasting crucible according to claim 1, is characterized in that: described limiting stand is cylinder.
