[0001] The utility model relates to the technical field of coal powder injection equipment, in particular to a quick-plugging coal gun device. Background Art

[0002] The development direction of blast furnaces is large-scale, intelligent, and efficient. Under current production conditions, to improve smelting intensity and increase molten iron output, traditional blast furnaces now use multiple injections of fuels such as pulverized coal and coke oven gas, and employ in-furnace oxygen enrichment technology to enhance the combustion of injected materials in front of the tuyere (most blast furnaces currently use pulverized coal as the injection material).

[0003] The main systems for pulverized coal injection (CPI) are divided into the following areas: flue gas system; coal grinding system; pulverized coal collection system; pulverized coal drop system; and pulverized coal injection system. After entering the raw coal bunker, the raw coal is ground and crushed by the pulverizer, removed by dust removal equipment, and then enters the pulverized coal bunker and the pulverized coal injection tank. After being pressurized by a mixture of compressed air and nitrogen, the coal enters the lance through a distributor and is transported to the interior of the blast furnace.

[0004] During the pulverized coal injection process, the following abnormal situations may occur: 1. The coal gun is burned out and needs to be replaced; 2. There is a problem with the air supply system, the blast furnace is shut down urgently, and the blowpipe is blown to fill the slag; when replacing the abnormal coal gun, 2-3 people are required to assist in the operation, 1 pipe clamp, and 1 sledgehammer, and the operation is very intensive.

[0005] The present application provides a quick-plug coal gun device to solve the above problems. Summary of the Invention

[0008] Furthermore, the coal gun fixing piece is used to be clamped on the coal gun, and the coal gun fixing piece is a fixing buckle, and the inner layer of the fixing buckle is fixedly installed with a wear-resistant layer.

[0009] Furthermore, the coal gun fixing piece is used to be clamped on the coal gun, and the coal gun fixing piece is a fixing clip, and a wear-resistant layer is provided on the surface of the fixing clip that contacts the coal gun.

[0010] Furthermore, the angle adjustment mounting seat includes a first bracket and a rotating mounting frame, the first bracket is fixedly mounted on the support frame, and the rotating mounting frame is rotatably connected to the first bracket.

[0011] Furthermore, the support frame includes a support platform and several support legs. The support platform is fixedly connected to the first bracket by a bolt and nut structure. The first bracket is installed on the upper surface of the support platform, and several support legs are rotatably installed on the lower surface of the support plane.
