Description

Technical Field

[0001] This utility model relates to the technical field of high temperature and high pressure fluid processing equipment, specifically a silicon carbide ceramic liner fixing and sealing device. Background Technology

[0002] Due to their excellent physicochemical properties, silicon carbide ceramics are widely used as key lining materials in high-temperature and high-pressure fluid handling equipment in chemical, metallurgical, and energy fields. For example, in scenarios such as pipelines for transporting highly corrosive media, high-temperature reactors, and coal chemical gasification furnaces, silicon carbide ceramic linings can effectively isolate fluids from the metal matrix, significantly extending the service life of the equipment. In order to ensure the full utilization of its performance and the reliability of industrial applications, the development of a silicon carbide ceramic lining fixing and sealing device is of great practical significance.

[0003] Referring to the silicon carbide ceramic liner irregular part with announcement number CN220102505U, it includes a tapered tube section, with a large-diameter section and a small-diameter section connected to both ends of the tapered tube section. The large-diameter section is provided with a large hole and a small hole respectively. An inner platform is provided on the inner side of the large-diameter section where the large hole and the small hole are located. The large hole and the small hole both penetrate the inner platform. An auxiliary platform is provided on the inner sidewall of the large-diameter section between the two inner platforms. The auxiliary platform has the same structure as the inner platform. As can be seen from the above, although this device can be applied well, it is usually not convenient to quickly install the liner onto the liner kit, which makes the installation process somewhat inconvenient and needs to be improved. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silicon carbide ceramic liner fixing and sealing device, comprising a base ring, a bushing fixed at one end of the base ring, a hexagonal connecting seat installed at the end of the base ring away from the bushing, an upper strip groove provided on the inner wall of one side of the bushing, a lower strip groove provided on the inner wall of the other side of the bushing, a silicon carbide ceramic liner installed at the end of the bushing away from the base ring, an upper strip block inserted into the upper strip groove, one end of the upper strip block being fixedly connected to the inner wall of the silicon carbide ceramic liner, a lower strip block inserted into the lower strip groove, one end of the lower strip block extending to the outside of the lower strip groove and fixedly connected to the inner wall of the silicon carbide ceramic liner.

[0006] Preferably, the base ring on the outer side of the bushing is provided with a plurality of positioning holes, and each positioning hole is fitted with a locking bolt. One end of the locking bolt is threaded to the outer wall of the hexagonal connector. By unscrewing one end of the locking bolt to the outside of the hexagonal connector, the base ring can be removed from the hexagonal connector.

[0007] Preferably, a hexagonal sealing disc is installed at the end of the hexagonal connector away from the base ring, and a connecting post is fixedly installed at one end of the hexagonal connector inside the hexagonal sealing disc. The connecting post is provided to accommodate the external thread.

[0008] Preferably, the inner wall of the hexagonal connector is provided with an internal thread, and the outer wall of the connecting post is provided with an external thread. The external and internal threads are provided to allow the connecting post to be screwed into the interior of the hexagonal connector.

[0009] Preferably, an annular handle is provided at the end of the hexagonal sealing disc away from the hexagonal connecting seat, and an arc-shaped rotating handle is fixedly installed at the bottom end of the annular handle, so that the hexagonal sealing disc can be rotated.

[0010] Preferably, the arc-shaped handle has an arc-shaped groove inside, and both ends of the arc-shaped groove extend to the outside of the arc-shaped handle. The arc-shaped groove is provided to enable the arc-shaped handle to be rotated.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the silicon carbide ceramic liner fixing and sealing device not only improves the convenience of installing silicon carbide ceramic liner parts, but also improves the sealing performance of the fixing and sealing device during use, and achieves the purpose of easy disassembly and maintenance of the fixing and sealing device.

[0012] (1) By inserting the upper strip block and the lower strip block into the upper strip groove and the lower strip groove respectively, the silicon carbide ceramic liner can be quickly installed on one end of the bushing, thereby improving the convenience of installing the silicon carbide ceramic liner.

[0013] (2) By rotating the arc-shaped handle, the hexagonal sealing disc is driven to rotate through the annular handle seat. Due to the setting of external and internal threads, the connecting column is screwed into the interior of the hexagonal connecting seat, and the hexagonal sealing disc is installed at one end of the hexagonal connecting seat, so as to perform sealing work on the rear end of the base ring, thereby improving the sealing performance of the fixed sealing device during use.

[0014] (3) By tightening the locking bolt, one end of the locking bolt is screwed out to the outside of the hexagonal connector, and the base ring can be removed from the hexagonal connector, thereby achieving the purpose of easy disassembly and maintenance of the fixed sealing device.

[0027] An annular handle 6 is provided at the end of the hexagonal sealing disc 5 away from the hexagonal connecting seat 4, and an arc-shaped rotating handle 7 is fixedly installed at the bottom end of the annular handle 6.

[0028] In use, the arc-shaped handle 7 is used to rotate the hexagonal sealing disc 5.

[0029] The inside of the arc-shaped handle 7 is provided with an arc-shaped groove 8, and both ends of the arc-shaped groove 8 extend to the outside of the arc-shaped handle 7.

[0030] In use, the arc-shaped groove 8 is provided to allow the arc-shaped handle 7 to be rotated.
