To improve the efficiency of incinerators, wear-resistant refractory castables are usually installed on the inner wall of the incinerator for coke removal and demolition. However, during coke removal operations, ordinary decoking tools are not only inefficient, but also damage the wear-resistant refractory castable layer due to the varying thickness of the coke layer in different parts of the furnace.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figures 1 to 4As shown, this embodiment provides a furnace lining for an incinerator made of wear-resistant refractory castable, including a furnace body 1. The furnace body 1 has a combustion chamber and a feeding port 101 communicating with the combustion chamber. The top and side walls of the combustion chamber of the furnace body 1 are provided with wear-resistant refractory castable layers 102. A coke removal mechanism 2 is provided on one side of the feeding port 101. The coke removal mechanism 2 includes a mounting frame 202 and a vibration mechanism. The mounting frame 202 is mounted on one side of the furnace body 1 through a sliding frame 201. A through hole coaxial with the upper end of the mounting frame 202 is opened. A U-shaped frame 203 is rotatably mounted in the through hole. The vibration mechanism is rotatably mounted on the upper end of the U-shaped frame 203 through a horizontal rotating shaft 204.

[0019] The vibration mechanism includes a mounting rod 205 that is connected to the horizontal rotating shaft 204. The first end of the mounting rod 205 extends into the combustion chamber, and the second end of the mounting rod 205 is provided with a counterweight 206. A vibration motor 207 is mounted on the first end of the mounting rod 205. A coke-breaking rod 208 is provided at the output end of the vibration motor 207. A rod tip is provided at the front end of the coke-breaking rod 208. A limit cover 210 is installed on the coke-breaking rod 208 in an adjustable position. In this embodiment, the vibration mechanism is installed and positioned by a sliding frame 201. A combustion platform 103 is provided at the bottom of the furnace body 1. The sliding frame 201 is horizontally movable on the combustion platform 103 by a slider. When performing coke removal, the sliding frame 201 is pushed so that the first end of the mounting rod 205 extends into the combustion chamber. The second end of the mounting rod 205 is rotated to contact the inner wall of the combustion chamber to perform the coke removal operation.

[0020] In this embodiment, the coke-breaking rod 208 has multiple connecting holes 211 arranged along its axis. The limiting cover 210 is installed at one of the connecting holes 211 by a positioning rod. The working length of the coke-breaking rod 208 is adjusted by adjusting the position of the limiting cover 210. The longer the coke-breaking rod 208 in front of the limiting cover 210, the thicker the coke layer can be broken. Preferably, the coke-breaking rod 208 in this embodiment can be set as an L-shaped coke-breaking rod 212. The L-shaped coke-breaking rod 212 has multiple connecting holes 211. The limiting cover 210 is installed at one of the connecting holes 211 by a positioning rod. The inner wall of the furnace body 1 has a flat surface and an arc surface. The L-shaped coke-breaking rod 212 can break the coke layer on the arc-shaped top wall of the furnace body 1.

[0021] In this embodiment, a movable block 213 can be installed on the horizontal rotating shaft 204. The movable block 213 is provided with a through hole, and the axis of the through hole is perpendicular to the axis of the horizontal rotating shaft 204. The mounting rod 205 can be rotatably installed in the through hole. When performing decoking operations, rotating and flipping the mounting rod 205 can break down different positions on the inner wall of different furnace bodies 1.

[0022] In this embodiment, when the furnace of an incinerator with wear-resistant refractory castable is undergoing decoking, the sliding frame 201 is pushed close to the furnace body 1, and the second end of the mounting frame 202 is inserted into the combustion chamber of the furnace body 1. Then, the vibration motor 207 is started, which drives the decoking rod 208 to vibrate and rotate and flip the mounting rod 205 from time to time, so that the decoking rod 208 moves in various parts of the combustion chamber. When performing decoking, the position of the limiting cover 210 should be adjusted according to the thickness of the coke layer to avoid the rod tip damaging the wear-resistant refractory castable layer 102.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
