Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a ceramic patch for lining a pipeline. Background Art

[0002] The wear-resistant ceramic pipe lined with the steel pipe has fully utilized the high strength, good toughness, impact resistance, good welding performance of the steel pipe and the high hardness, high wear resistance, corrosion resistance and good heat resistance of the corundum porcelain, overcoming the characteristics of low hardness, poor wear resistance and poor toughness of the steel pipe. Most of the ceramic sheets inside the pipe are fixed by bonding, which is easy to fall off after a certain period of use, and the ceramic sheets are also more complicated to install, resulting in more difficult maintenance of the pipeline in the later stage. The high-strength preheater inner cylinder ceramic hanging sheet proposed by the prior art publication number CN217877146U has an arc-shaped cross section of the ceramic hanging sheet, and the ceramic hanging sheet is a thick upper and thin lower structure. A fixing strip is provided on one side of the ceramic hanging sheet, and a fixing groove is provided on the other side of the ceramic hanging sheet. The fixing strip and the fixing groove are matched, and the upper connecting hole and the lower connecting hole are respectively provided on the ceramic hanging sheet. The air tightness is improved, the stress concentration is reduced, and the overall strength and stability of the ceramic hanging sheet can be improved. However, the semicircle of the fixing strip is too small, the locking effect is poor, and it is easy to fall off. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a ceramic patch for pipeline lining which has improved locking effect, more stable connection and is not easy to fall off.

[0004] The utility model discloses a pipeline lining ceramic patch, comprising a plurality of ceramic patches and a pipeline. The plurality of ceramic patches are evenly arranged and installed on the inner wall of the pipeline. A clamping protrusion is installed at one end of the ceramic patch, and a clamping groove matching the clamping protrusion is opened at the other end of the ceramic patch. The plurality of ceramic patches are locked together by the clamping protrusion and the clamping groove to form a circular ring, which will not fall off. The utility model is suitable for large-diameter pipelines, improves the locking effect, makes the connection more stable, and is not easy to fall off.

[0005] Preferably, the protrusion is arranged to be a trapezoid, and the groove is arranged to be a dovetail groove matching the protrusion, so that the protrusion and the groove form a dovetail tenon structure; compared with the traditional connection method, the installation process of the dovetail groove is simpler and faster, and it only needs to be inserted at the corresponding position. The dovetail groove makes the connection surface more stable and reliable, and not easy to loosen. The dovetail tenon structure can enhance the pulling force of the mortise and tenon combination, greatly improving the stability of the connection.

[0006] Preferably, the upper and lower ends of the clamping protrusion are arranged in an arc shape; the clamping protrusion is arranged in an arc shape, which can further improve the convenience during splicing and installation, and avoid damage to the pipe wall caused by sharp angles.

[0007] Preferably, small latching protrusions are provided at the upper and lower ends of the slot, and small slots matching the small latching protrusions are provided at the upper and lower ends of the latching protrusions; when the latching protrusion is inserted into the slot, the small latching protrusion is inserted into the small slot to ensure the stability after connection, further avoid falling off after engagement, and the double latching connection is more stable and not easy to fall off.

[0008] Compared with the prior art, the utility model has the following beneficial effects: a plurality of ceramic patches are locked together by means of the locking protrusions and the locking grooves to form a circular ring, which will not fall off. The utility model is suitable for large-diameter pipes, improves the locking effect, makes the connection more stable, and is not easy to fall off. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings. The utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0016] like Figures 1 to 5 As shown, a plurality of ceramic patches 1 are evenly arranged and installed on the inner wall of a pipe 4, a protrusion 2 is installed at one end of the ceramic patch 1, a slot 3 matching the protrusion 2 is provided at the other end of the ceramic patch 1, the protrusion 2 is arranged in a trapezoidal shape, the slot 3 is arranged in a dovetail groove matching the protrusion 2, so that the protrusion 2 and the slot 3 form a dovetail structure, the upper and lower ends of the protrusion 2 are arranged in an arc shape, the upper and lower ends of the slot 3 are provided with a small protrusion 5, and the upper and lower ends of the protrusion 2 are provided with a small slot 6 matching the small protrusion 5;

[0017] Multiple ceramic patches 1 are locked together by the locking protrusion 2 and the slot 3 to form a ring, which will not fall off and is suitable for large-diameter pipes. Compared with the traditional connection method, the installation process of the dovetail groove is simpler and faster. It only needs to be inserted at the corresponding position. The dovetail groove makes the connection surface more stable and reliable and not easy to loosen. The dovetail tenon structure can enhance the pulling force of the mortise and tenon connection, greatly improving the stability of the connection. The arc shape of the locking protrusion 2 can further improve the convenience of splicing installation and avoid damage to the pipe wall caused by sharp angles. When the locking protrusion 2 is inserted into the slot 3, the small locking protrusion 5 is inserted into the small slot 6 to ensure the stability after connection and further avoid falling off after locking. The double clamping connection is more stable and not easy to fall off.

[0018] like Figures 1 to 5 As shown, the utility model is a ceramic patch for lining a pipeline. When working, multiple ceramic patches 1 are connected end to end and locked with each other through the locking protrusion 2 and the locking groove 3 to form a circular ring, which will not fall off. The installation process of the dovetail groove is simpler and faster. It only needs to be inserted at the corresponding position. The dovetail tenon structure can enhance the pulling force of the mortise and tenon combination. When the locking protrusion 2 is inserted into the locking groove 3, the small locking protrusion 5 is inserted into the small locking groove 6, which further avoids falling off after locking.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
