Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic crucibles, in particular to a sealed ceramic crucible. Background Art

[0002] Traditional crucibles are mostly made of metal materials. However, due to the characteristics of metal materials themselves, they are difficult to apply to certain harsh reaction conditions such as strong corrosion and high temperature, and the price is relatively high. In modern times, emerging ceramic crucible products have a wide range of raw materials and are superior to crucibles made of traditional materials in terms of chemical corrosion resistance, high temperature resistance, and erosion resistance. Therefore, they are widely used in harsh working conditions such as fine chemical experiments, high-temperature calcination and melting.

[0003] However, due to the limitations of the processing properties of the ceramic material itself, the sealing contact surface structure of the ceramic crucible currently in common use is difficult to achieve tight sealing and can no longer meet the current technical requirements for increasingly high sealing performance, thus affecting the use effect of the ceramic crucible. Utility Model Content

[0004] The utility model aims to provide a sealed ceramic crucible to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sealed ceramic crucible, comprising a ceramic crucible body, a sealing assembly and a movable assembly; wherein the ceramic crucible body comprises a crucible body, a threaded block and a crucible cover; the threaded block is fixed on the crucible body; the crucible cover is threadedly connected to the threaded block; the sealing assembly is arranged on the threaded block; wherein the sealing assembly comprises a sealing groove and a sealing ring; a sealing groove is provided on a side of the threaded block away from the crucible body; the sealing ring is connected to the crucible cover through a movable assembly; wherein the sealing ring and the sealing groove constitute a sealed ceramic crucible.

[0006] As a preferred embodiment, the cross section of the sealing ring is a wave structure.

[0007] As a preferred embodiment, the movable component includes a movable ring groove, a movable ring block, a connecting plate A, a connecting plate B and a wedge-shaped elastic member; a movable ring groove is opened on the side of the crucible cover close to the threaded block; the movable ring block is arranged in the movable ring groove, and the end of the movable ring block passes through the movable ring groove and is fixedly connected to the sealing ring; a plurality of the connecting plates A are fixedly arranged in an annular array on the side of the movable ring block away from the sealing ring; a plurality of the connecting plates B are fixedly arranged in an annular array in the movable ring groove; and the two ends of the wedge-shaped elastic member are fixedly connected to the connecting plate A and the connecting plate B respectively.

[0008] As a preferred embodiment, the movable ring block is slidably matched with the movable ring groove.

[0009] As a preferred embodiment, the cross section of the movable ring block is T-shaped, and the dimension of the movable ring block on the side close to the sealing ring is smaller than the dimension of the movable ring block on the side away from the sealing ring.

[0010] As a preferred embodiment, the wedge-shaped elastic member is formed by a plurality of arc-shaped blocks.

[0011] As a preferred embodiment, a plurality of the arc-shaped blocks are staggered to form a wave-shaped structure.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0013] The sealed ceramic crucible is provided with a sealing component. When in use, the crucible cover is threadedly connected to the threaded block, and the crucible cover is moved toward the threaded block until the top surface of the threaded block contacts the inner top wall of the crucible cover. At this time, the sealing ring contacts the inner wall of the sealing groove, thereby completing the connection and sealing between the crucible body and the crucible cover. The mutual contact between the sealing ring and the sealing groove can improve the sealing performance of the ceramic crucible body, thereby improving the use effect of the ceramic crucible body.

[0014] The sealed ceramic crucible is provided with a movable ring groove, a movable ring block, a connecting plate A, a connecting plate B and a wedge-shaped elastic member, so that when the sealing ring contacts the inner wall of the sealing groove, the movable ring block slides in the movable ring groove, causing the wedge-shaped elastic member to be deformed by force until the top surface of the threaded block contacts the inner top wall of the crucible cover. Not only can the sealing ring still maintain good sealing performance with the sealing groove after being damaged by the wedge-shaped elastic member, but the wedge-shaped elastic member can also prevent the movable ring block from rotating in the movable ring groove during the rotation of the crucible cover, thereby improving the practicality of the utility model.
