[0011] Preferably, the guide rail has an arc-shaped dovetail shape, and the internal dimensions of the guide rail are slightly smaller than the dimensions of the arc-shaped dovetail groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This easily connected arc-shaped dovetail groove ceramic allows multiple ceramic liners to be spliced ​​together through two connecting grooves inside the ceramic liner, forming a ring-shaped protective layer to protect the inner wall of the pipe. Fastening bolts are installed inside the bottom flange via bolt holes, and the bottom flange also has bolt holes inside. Multiple flanged conveying pipes can be connected together using fastening bolts and nuts. Fasteners are threaded through the connecting holes and installed inside the conveying pipe, allowing the guide rail to be installed on the inner wall of the conveying pipe.

[0024] In this embodiment, by opening two connecting grooves 32 inside the ceramic liner 2, multiple ceramic liner plates 2 can be spliced ​​together through the connecting grooves 32 to form an annular protective layer to protect the inner wall of the pipe. By threading the fastening bolts 42 through the bolt holes 41 inside the bottom flange 4, and the bottom flange 2 also having bolt holes 41 inside, multiple flanged conveying pipes 1 can be connected together by fastening bolts 42 and fastening nuts 43. By threading the fasteners 52 through the connecting holes 51 inside the conveying pipe 1, the guide rail 5 can be installed on the conveying pipe. The inner wall of the conveying pipe 1 is fixedly installed inside the bottom flange 2 by the limiting ring 6, and the limiting ring 6 is located directly below the guide rail 5 and the ceramic liner 3. The limiting ring 6 can support the ceramic liner 3 and prevent the ceramic liner 3 from slipping. By installing multiple ceramic liners 3 in a circular array on the inner wall of the conveying pipe 1, the inner wall of the conveying pipe can be protected when the medium passes through the conveying pipe 1 at high speed. By setting the shape of the guide rail 5 to be arc-shaped dovetail and the internal size of the guide rail 5 is slightly smaller than the size of the arc-shaped dovetail groove 31, the ceramic liner 3 with the arc-shaped dovetail groove 31 can be slidably installed on the outside of the guide rail 5.

[0025] Specifically, the ceramic liner 3 has an arc-shaped dovetail groove 31 inside and a connecting groove 32 inside. There are two connecting grooves 32 inside the ceramic liner 2. By opening two connecting grooves 32 inside the ceramic liner 2, multiple ceramic liners 2 can be spliced ​​together through the connecting grooves 32 to form an annular protective layer to protect the inner wall of the pipe.

[0026] Specifically, the top flange 4 has a bolt hole 41 inside, and a fastening bolt 42 is installed in the internal thread of the bolt hole 41. A fastening nut 43 is installed in the external thread of the fastening bolt 42. The bottom flange 2 also has a bolt hole 41 inside. By installing the fastening bolt 42 in the inside of the bottom flange 4 through the bolt hole 41, and the bottom flange 2 also has a bolt hole 41 inside, multiple flanged conveying pipes 1 can be connected together by fastening bolts 42 and fastening nuts 43.

[0027] Specifically, the guide rail 5 has a connection port 51 inside, and a fastener 52 is installed inside the connection port 51 by thread. The fastener 52 passes through the connection port 51 and is threaded inside the conveying pipe 1.

[0028] Specifically, the limiting ring 6 is located inside the conveying pipe 1, and the limiting ring 6 is located directly below the guide rail 5 and the ceramic liner 3. By fixing the limiting ring 6 inside the bottom flange 2 and making the limiting ring 6 directly below the guide rail 5 and the ceramic liner 3, the limiting ring 6 can support the ceramic liner 3 and prevent the ceramic liner 3 from slipping.

[0029] Specifically, there are multiple ceramic liners 3, and these multiple ceramic liners 3 are installed in a circular array on the inner wall of the conveying pipe 1. By installing multiple ceramic liners 3 in a circular array on the inner wall of the conveying pipe 1, the inner wall of the conveying pipe can be protected when the medium passes through the conveying pipe 1 at high speed.

[0030] Specifically, the guide rail 5 has an arc-shaped dovetail shape, and the internal dimensions of the guide rail 5 are slightly smaller than the dimensions of the arc-shaped dovetail groove 31. By setting the shape of the guide rail 5 to an arc-shaped dovetail and the internal dimensions of the guide rail 5 to be slightly smaller than the dimensions of the arc-shaped dovetail groove 31, the ceramic liner 3 with the arc-shaped dovetail groove 31 can be slidably installed on the outside of the guide rail 5.

[0031] The working principle or usage process of this utility model is as follows: When using this utility model, firstly, the fastener 52 is threaded through the connection port 52 opened on the guide rail 5 and installed inside the conveying pipe 1. The guide rail 5 can be installed on the inner wall of the conveying pipe 1. Then, the ceramic liner 3 can be slidably installed on the outside of the guide rail 5 through the arc-shaped dovetail groove 31 opened inside the ceramic liner 3. Then, multiple ceramic liners 3 can be spliced ​​together through the connection groove 32 opened inside the ceramic liner 3, thereby forming a protective layer on the inner wall of the conveying pipe 1 to protect the inner wall of the conveying pipe 1. Since the limiting ring 6 is located directly below the guide rail 5 and the ceramic liner 3, the limiting ring 6 can support the ceramic liner 3 to prevent the ceramic liner 3 from slipping. Then, the fastening bolts and fastening nuts 43, which are threaded into the bolt ports 41 opened inside the bottom flange 2 and the top flange 4, can be used to connect multiple sections of the conveying pipe 1 to convey the medium. The electrical equipment in this device is all externally powered and is controlled by the matching control switch to operate and shut down.
