Description

Technical Field

[0001] The invention relates to the technical field of wear-resistant ceramic pipes, in particular to a wear-resistant ceramic pipe. Background Art

[0002] Wear-resistant ceramic pipes are composed of three layers from the inside to the outside: ceramic layer, transition layer, and steel layer. The ceramic layer is formed into dense corundum porcelain at a high temperature of more than 2200°C, and forms a firm bond with the steel pipe through the transition layer.

[0003] Wear-resistant ceramic pipes include several types, such as centrifugally cast composite ceramic pipes, patch wear-resistant ceramic pipes, spot-welded card-type wear-resistant ceramic pipes, etc. Among them, patch wear-resistant ceramic pipes use high-temperature resistant strong adhesive to stick alumina ceramic sheets to the inner wall of the pipe, and form a solid anti-wear layer after heating and curing. The manufacturing process of this product is relatively simple, the manufacturing cycle is short, and the cost is relatively low. However, in actual use, there is a situation where the adhesive fails and the alumina ceramic sheet falls off. The spot-welded card-type wear-resistant ceramic pipe uses a high-temperature resistant strong adhesive to stick the alumina ceramic sheet with a hole in the middle to the inner wall of the pipe, and at the same time uses the spot welding process to firmly weld the ceramic to the inner wall of the steel pipe through the small hole, which can effectively avoid the situation where the adhesive fails and the alumina ceramic sheet falls off. However, whether it is a patch wear-resistant ceramic pipe or a spot-welded card-type wear-resistant ceramic pipe, the fixing method of the alumina ceramic sheet in both pipes has usage defects: when the alumina ceramic sheet is damaged, it is not convenient to disassemble and replace the damaged alumina ceramic sheet, and when the damaged alumina ceramic sheet is violently removed, it is easy to damage the adjacent alumina ceramic sheet.

The following describes an embodiment of the present invention based on its overall structure.

[0029] See also Figures 1 to 10 In an embodiment of the present invention, a wear-resistant ceramic pipe includes a steel pipe 1 and a ceramic lining assembly 2. An installation assembly 3 is provided inside the steel pipe 1, and the installation assembly 3 is used to realize the fixed installation operation of the ceramic lining assembly 2; the installation assembly 3 includes a pre-fixing unit, a reinforcement unit, and a filling unit; the pre-fixing unit is used to realize the pre-fixed installation of the ceramic lining assembly 2; the reinforcement unit is used to realize the reinforcement and fixation of the ceramic lining assembly 2; the filling unit is used to fill the space between the ceramic lining assembly 2 and the pre-fixing unit and to seal the two ends of the reinforcement unit.

[0030] The pre-fixed unit includes a fixed inner cylinder 301, a rectangular mounting hole 302, a fixed straight beam 304, and an arc-shaped elastic card 305; there are multiple fixed straight beams 304, and the multiple fixed straight beams 304 are evenly distributed along the circumference and fixed to the outside of the fixed inner cylinder 301, and the fixed inner cylinder 301 is fixed to the inside of the steel pipe 1 through the fixed straight beams 304; there are multiple groups of rectangular mounting holes 302, each group of rectangular mounting holes 302 includes multiple rectangular mounting holes 302 evenly distributed along the long side direction of the fixed inner cylinder 301, and the multiple groups of rectangular mounting holes 302 are staggered with the multiple fixed straight beams 304 along the circumferential direction.

[0031] The arc-shaped elastic clips 305 are symmetrically formed on both sides of the outer wall of the fixed straight beam 304. There are multiple arc-shaped elastic clips 305 evenly arranged in the horizontal direction and corresponding to the positions of the rectangular mounting holes 302. The arc-shaped elastic clips 305 on the side where two adjacent fixed straight beams 304 are close to each other are symmetrically distributed with the rectangular mounting hole 302 as the center.

[0032] The ceramic lining assembly 2 includes a T-shaped ceramic arc piece 201 and a snap-in groove 203. The outer wall size of the small-sized part of the T-shaped ceramic arc piece 201 matches the inner wall of the rectangular mounting hole 302. The snap-in groove 203 is symmetrically opened on both sides of the outer wall of the small-sized part of the T-shaped ceramic arc piece 201. When the T-shaped ceramic arc piece 201 is snapped into the rectangular mounting hole 302 through the small-sized part, the arc-shaped elastic card 305 is snapped into the inner side of the snap-in groove 203 to realize the pre-fixed installation of the T-shaped ceramic arc piece 201.

[0033] The reinforcement unit includes an arc-shaped straight rod 307; an iron arc tube 202 is pre-buried inside the small-sized part of the T-shaped ceramic arc piece 201, and the two ends of the iron arc tube 202 are flush with the two ends of the outer wall of the T-shaped ceramic arc piece 201; the arc-shaped straight rod 307 extends through the iron arc tube 202 on multiple horizontally distributed T-shaped ceramic arc pieces 201 and the inner arc surface of the arc-shaped straight rod 307 is tightly fitted with the outer wall of the fixed inner tube 301, which is used to achieve synchronous reinforcement and fixation of multiple horizontally distributed T-shaped ceramic arc pieces 201.

[0034] The filling unit includes a grille groove 303, a threaded hole 306, a rubber filling layer 309, and a sealing ring 310; the grille groove 303 is integrally formed on the inner side of the fixed inner cylinder 301, the rectangular mounting hole 302 and the grille groove 303 are not connected to each other, the rubber filling layer 309 is filled in the inner side of the grille groove 303, and the inner surface of the rubber filling layer 309 protrudes from the inner surface of the fixed inner cylinder 301 in the initial state.

[0035] When the T-shaped ceramic arc piece 201 is installed on the inner side of the rectangular mounting hole 302, the outer side of the large-size part of the T-shaped ceramic arc piece 201 is tightly fitted and squeezed against the inner surface of the rubber filling layer 309. The rubber filling layer 309 is used to provide a buffer for the contact between the T-shaped ceramic arc piece 201 and the fixed inner cylinder 301, while realizing the splicing and sealing of multiple T-shaped ceramic arc pieces 201.

[0036] The two ends of the fixed straight beam 304 are sealed structures, and the threaded holes 306 are symmetrically opened at the two ends of the fixed straight beam 304; the blocking ring 310 is fitted on the two ends of the fixed inner tube 301 and is fixed by bolts and threaded connections with the threaded holes 306. The two ends of the arc straight rod 307 are flush with the two ends of the fixed inner tube 301 and fit with the end faces of the two blocking rings 310. The two blocking rings 310 are used to achieve blocking and limiting of the arc straight rod 307.

[0037] In this embodiment, the steps for assembling the wear-resistant ceramic pipe are as follows:

[0038] In the first step, the fixed inner tube 301 and fixed straight beam 304 are integrally fixed within the steel pipe 1. The ends of the fixed inner tube 301 are spaced a certain distance from the ends of the steel pipe 1 to accommodate the installation of the blocking ring 310. It should be noted that the fixed straight beam 304 and the steel pipe 1 can be fixed together using adhesive or welding. In addition, a rubber filling layer 309 is pre-installed inside the grille groove 303.

[0039] The second step is to install the ceramic lining assembly 2. First, take a set of ceramic lining assemblies 2, align the small-sized part of the T-shaped ceramic arc piece 201 with a rectangular mounting hole 302 and insert it. During this process, the opening of the iron arc tube 202 needs to be facing the two ends of the steel pipe 1. When the small-sized part of the T-shaped ceramic arc piece 201 is inserted into the rectangular mounting hole 302, it will contact and squeeze the arc-shaped elastic card 305, causing the arc-shaped elastic card 305 to deform and shrink into the inside of the fixed straight beam 304 (it should be noted that the inside of the fixed straight beam 304 is a cavity structure). In this way, the arc-shaped elastic card 305 will not block the installation of the T-shaped ceramic arc piece 201. When the snap-fitting groove 203 on the T-shaped ceramic arc piece 201 is aligned with the position of the arc-shaped elastic card 305, the arc-shaped elastic card 305 will be reset and clamped into the inner side of the snap-fitting groove 203 under the action of its own elastic force, thus realizing the pre-fixed installation of the T-shaped ceramic arc piece 201. Then, the other ceramic lining assemblies 2 can be installed according to the above-mentioned operating steps.

[0040] During this process, when the large-sized part of the T-shaped ceramic arc piece 201 approaches the fixed inner cylinder 301, it will first contact the rubber filling layer 309 protruding from the inner side of the fixed inner cylinder 301, and squeeze the rubber filling layer 309 so that its inner surface is finally flush with the inner surface of the fixed inner cylinder 301. Through this structure, not only can the installation of the T-shaped ceramic arc piece 201 be buffered to avoid excessive hard collision force between the large-sized part of the T-shaped ceramic arc piece 201 and the fixed inner cylinder 301, but also, when all T-shaped ceramic arc pieces 201 are installed, the rubber filling layer 309 can form a sealing layer between the lower surface of the large-sized part of the T-shaped ceramic arc piece 201 and the fixed inner cylinder 301, so that during the later use of the pipeline, the internal conveyed objects will not contact the fixed inner cylinder 301 and the steel pipe 1.

[0041] The third step is to take the arc straight rod 307, and pass the arc straight rod 307 through multiple horizontally distributed T-shaped ceramic arc pieces 201 from one end of the steel pipe 1 in sequence. The arc straight rod 307 passes through the iron arc tubes 202 on multiple T-shaped ceramic arc pieces 201, so as to achieve the installation and reinforcement of the T-shaped ceramic arc piece 201. This structure can effectively prevent the T-shaped ceramic arc piece 201 from loosening and falling.

[0042] In the fourth step, two sealing rings 310 are respectively installed at the two ends of the fixed inner tube 301. The sealing rings 310 form a limit clamping for the two ends of the arc-shaped straight rod 307, thus completing the assembly of the entire wear-resistant ceramic pipe.

[0043] Through the cooperation of the above-mentioned multiple parts, the installation of the T-shaped ceramic arc piece 201 does not require glue, the installation operation is more convenient and efficient, and the installation is more stable, which can effectively prevent the T-shaped ceramic arc piece 201 from loosening and falling. In addition, when the T-shaped ceramic arc piece 201 is damaged, it is only necessary to disassemble the entire pipe, remove a sealing ring 310, and then pull out the arc straight rod 307 corresponding to the T-shaped ceramic arc piece 201 to be replaced. After that, the T-shaped ceramic arc piece 201 to be replaced is adsorbed and pulled by the suction cup or magnetic block, so that the T-shaped ceramic arc piece 201 to be replaced can be easily removed, and then the new T-shaped ceramic arc piece 201 is installed in turn, and the arc straight rod 307 and the sealing ring 310 can be restored (it should be noted that the iron arc cylinder 202 is used to be magnetically attracted by the magnetic block to achieve the convenient removal of the T-shaped ceramic arc piece 201; a strong pneumatic suction cup can also be used to align with the inner side of the T-shaped ceramic arc piece 201 for suction and removal).

[0044] Please refer to Figures 4 to 8 The two ends of the iron arc tube 202 are in a trumpet-shaped structure. The outer wall size of the arc straight rod 307 matches the inner wall size of the iron arc tube 202. Buckle grooves 308 are opened at both ends of the arc straight rod 307.

[0045] In this embodiment: through the structure of the flared ends of the iron arc tube 202, the arc straight rod 307 can be inserted into the interior of the iron arc tube 202 more smoothly, and when the arc straight rod 307 and the iron arc tube 202 are mutually socketed, the T-shaped ceramic arc piece 201 is completely fixed and will not become loose.

[0046] The buckle groove 308 is structurally provided to provide a force point for later disassembly of the arc-shaped straight rod 307 . By hooking and pulling the buckle groove 308 with a hook-shaped tool, the arc-shaped straight rod 307 can be conveniently disassembled.

[0047] Please refer to Figures 1 to 10 A "T"-shaped hole corresponding to the sealing ring 310 is opened on the fixed inner cylinder 301. The vertical cross-section of the sealing ring 310 is a "7"-shaped structure, and the inner horizontal part of the sealing ring 310 extends to the inner side of the fixed inner cylinder 301 and fits with the end faces of the T-shaped ceramic arc pieces 201 distributed at both ends; the inner diameters of the large-sized parts of the multiple T-shaped ceramic arc pieces 201 distributed along the circumferential direction match the inner diameter of the sealing ring 310, and the outer diameters of the large-sized parts match the inner diameter of the fixed inner cylinder 301; the end faces of the two sealing rings 310 that are away from each other are flush with the two ends of the steel pipe 1.

[0048] In this embodiment: It should be additionally explained that: the sealing ring 310 is made of high-strength, wear-resistant and corrosion-resistant alloy material. The sealing ring 310 can protect the end faces of the T-shaped ceramic arc pieces 201 at both ends, thereby preventing the T-shaped ceramic arc pieces 201 at both ends from colliding with external objects and being damaged during daily transportation or installation. When the steel pipe 1 is installed on the conveying pipeline, the sealing ring 310 will not affect the installation seal between the steel pipe 1 and the conveying pipeline.

[0049] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
