Description

Technical Field

[0001] This utility model relates to the field of anti-wear tile technology, specifically a quick-replacement component for anti-wear tiles inside the superheater outlet pipe. Background Technology

[0002] Wear-resistant tiles, also known as wear-resistant covers, wear-resistant plates, wear-resistant protective tiles, wear-resistant cover plates, corrosion-resistant cover plates, boiler climbing pipes, wear-resistant pressure plates, etc., are common accessories for the heating surface tubes of power plant boilers. Wear-resistant tiles are mainly used on the windward side of the heating surface tubes of boilers such as superheaters, reheaters, economizers, and water-cooled wall pipes. Their main function is to protect the windward side of boiler pipes, reduce pipe wear, and increase the service life of the heating surface tubes.

[0003] A search revealed that patent application CN217329770U discloses an easy-to-install anti-wear tile assembly, comprising an anti-wear tile body and connectors. The anti-wear tile body includes a central anti-wear main body with a basically U-shaped cross-section and a first anti-wear part and a second anti-wear part connected to both ends of the central anti-wear main body. The cross-sections of the first and second anti-wear parts are both basically U-shaped, and the inner diameter of the U-shape of the first and second anti-wear parts is larger than the inner diameter of the U-shape of the central anti-wear main body. This facilitates the installation of the anti-wear tile assembly and provides a large protection range.

[0004] However, due to the design of the anti-wear tile body and the anti-wear part, the anti-wear tile body and the anti-wear part are connected by a plug-in method, which has low connection stability and is prone to falling off. At the same time, due to the design of the anti-wear tile body, the anti-wear tile body is prone to relative rotation with the air outlet pipe under the action of wind, causing the anti-wear tile to detach from the air outlet pipe surface that should be protected, resulting in poor performance.

[0005] Therefore, we propose a quick-replacement assembly for the anti-wear tiles inside the superheater outlet pipe. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a quick-replacement component for the anti-wear tiles inside the superheater outlet pipe, which solves the problems of low installation stability and poor performance of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a quick-replacement assembly for the anti-wear tile inside the superheater outlet pipe, comprising an anti-wear tile body, wherein the cross-section of the anti-wear tile body is U-shaped, and an outlet pipe is assembled on the inner wall of the front side of the anti-wear tile body.

[0008] The right side of the wear-resistant tile body has five sets of corresponding connecting holes, the left side of the wear-resistant tile body has five sets of matching connecting rods, the right side of the wear-resistant tile body has two sets of corresponding through holes, the through holes are fitted with matching limiting rods, the left end of the limiting rod is fixedly fitted with a rod cap, the outer wall of the right end of the limiting rod is provided with a threaded groove, and the threaded groove is fitted with a matching nut.

[0009] A fixed plate of the same specification is fixedly installed on the rear side of the wear-resistant tile body. The wear-resistant tile body and the fixed plate form a closed loop. A threaded rod of the same specification is threadedly assembled on the rear side of the fixed plate. A fixed cap is fixedly installed at the rear end of the threaded rod, and a limiting plate of the same specification is fixedly installed at the front end of the threaded rod.

[0010] Preferably, the front side of the limiting plate is fixedly equipped with evenly distributed anti-slip blocks, which can improve the anti-slip performance of the limiting plate and thus improve the stability between the wear-resistant tile and the air outlet pipe.

[0011] Preferably, the anti-slip block is made of rubber material and is shaped like a frustum, which can prevent the limiting plate from damaging the air outlet pipe.

[0012] Preferably, the outer wall of the fixing cap is fitted with a rubber layer, which can improve the anti-slip properties of the fixing cap and make it easier for workers to move the threaded rod by manually rotating the fixing cap.

[0013] Preferably, the fixing cap has a hexagonal groove on its rear side, which allows the fixing cap to be rotated using a hexagonal wrench, improving convenience.

[0014] Preferably, the length of the wear-resistant tile body is 20cm, so that a single person can install the wear-resistant tile, reducing labor costs.

[0015] 1. This quick-replacement assembly for anti-wear tiles inside a superheater outlet pipe, through the setting of connecting holes, connecting rods, and limiting rods, first installs multiple sets of anti-wear tile bodies on the outer wall of the outlet pipe. The multiple sets of anti-wear tile bodies are connected to each other through connecting rods and connecting holes. Then, a limiting rod of appropriate specification is inserted into the through hole, with the rod cap fitting against the leftmost anti-wear tile body. Finally, a nut is installed on the limiting rod to limit and fix the rightmost anti-wear tile body, ensuring the stability of the overall installation.

[0016] 2. Simultaneously, by setting the threaded rod and the limiting plate, the wear-resistant tile body is installed after the air outlet pipe. By rotating the fixing cap, the threaded rod is rotated, thereby moving the limiting plate towards the air outlet pipe. The limiting plate and the air outlet pipe come into contact and squeeze each other, thereby ensuring that the wear-resistant tile as a whole does not rotate relative to the air outlet pipe, thus improving the effect of the wear-resistant tile.

[0029] The working principle and usage process of this utility model are as follows: When the device is required to work, first install multiple sets of anti-wear tile bodies 1 on the outer wall of the air outlet pipe 2. The multiple sets of anti-wear tile bodies 1 are connected by connecting rods 5 and connecting holes 4. Then, insert a suitable limiting rod 7 into the through hole 6. The rod cap 8 fits against the leftmost anti-wear tile body 1. Then, install the nut 10 on the limiting rod 7 to limit and fix the right side anti-wear tile body 1, ensuring the stability of the overall installation. After installing the anti-wear tile body 1 on the air outlet pipe 2, rotate the fixing cap 12 to drive the threaded rod 11 to rotate, thereby driving the limiting plate 13 to move towards the air outlet pipe 2. The limiting plate 13 and the air outlet pipe 2 come into contact and squeeze, thereby ensuring that the anti-wear tile as a whole does not rotate relative to the air outlet pipe 2, improving the effect of the anti-wear tile.
