Problems solved by technology
However, the existing sampling technology, such as: the optical sampling tube material depth measurement technology of the blast nozzle sampling machine, the drilling and pushing action during sampling will compress the coke in the tube, and it will be disturbed by the high concentration of dust during sampling. Unable to perform the measurement function, resulting in a serious error in the calculation of the subsequent coke compression rate, and the relative position of the sampled material in the blast furnace cannot be restored

Embodiment Construction
[0016] Please refer to FIG. 1. FIG. 1 is a schematic diagram showing a blast furnace coke sampling machine 100 according to an embodiment of the present invention, which includes a sampling pipe 110, a microwave ranging system 120, a sampling control system and a compression rate calculation system (not shown). Please refer to FIG. 2 , the sampling personnel control the sampling machine 100 to enter the interior of the blast furnace to obtain coke samples to analyze the combustion conditions in the blast furnace. The blast furnace has a furnace body 210 in which coke 220 and iron ore 230 are laid. When the coke reacts with the iron ore, air is sent into the blast furnace through the tuyeres 212 to provide the oxygen required for the reaction between the coke and the iron ore. When the blast furnace is shut down, the sampling personnel will control the sampling machine 100 to obtain coke samples through the tuyeres 212 . It should be noted that when the coke 220 and the iron o...

The invention discloses a blast furnace coke sampling machine and a blast furnace coke sampling method. The blast furnace coke sampling machine comprises a sampling tube, a microwave range finding system, a sampling control system and a compression ratio calculating system, wherein the sampling tube comprises a tube body and a movable baffle plate; and the tube body has two opposite end portions, and the movable baffle plate is arranged in the tube body to form an accommodation space with the tube end portions in order to accommodate a coke sample. The coke sampling method comprises the following steps: 1, providing the sampling tube; 2, utilizing the sampling control system to move the sampling tube a sampling distance in order to take the coke sample; 3, utilizing the microwave range finding system to measure the movement distance of the movable baffle plate; and 4, utilizing the compression ratio calculating system to calculate according to the sampling distance and the baffle plate movement distance in order to obtain the compression ratio of the coke sample.
Description
technical field [0001] The invention relates to a blast furnace coke sampling machine and a blast furnace coke sampling method, in particular to a blast furnace coke sampling machine capable of calculating compressibility and a blast furnace coke sampling method. Background technique [0002] Blast furnace is a method of ironmaking. The principle is to add iron ore with 50-60% iron content to a flux for removing impurities. The main components of the flux are limestone, silica, fluorite, and then layered and packed together with coke. into the blast furnace. High-temperature hot air is blown from the tuyere of the blast furnace. At high temperature, the carbon in the coke burns to form carbon monoxide and undergoes a redox reaction with the iron ore. The iron ore is smelted into pig iron through the reduction reaction, and the molten iron is released from the tap hole. [0003] During this process, coke plays the role of heat source and reducing agent, and also plays the ro...
