Description

Full-automatic coal blending method for SCO furnace simulated coking Technical Field The invention relates to the technical field of industrial coking, in particular to a full-automatic coal blending method for SCO furnace simulated coking. Background In SCO furnace simulated coking, the coal blending process is a key link for determining coke quality, different coal types are required to be mixed according to a specific formula, and meanwhile, the moisture, granularity and mixing uniformity of the coal samples are controlled. The SCO furnace is test equipment for highly reducing a real coke furnace process, is mainly used for single coal/blending coal performance detection, new coal development, coke quality prediction and the like, and provides data support for optimized production by simulating an industrial coking process under laboratory conditions. The existing coal blending technology has the following defects: 1. the manual dependence is high, the links of sample receiving, coal sample transferring, label pasting, empty barrel recycling and the like are dependent on manual operation, the efficiency is low, and the mismatching of coal sample information is easy to cause due to human errors; 2. The difficult problem of wet coal crushing is that the wet coal (the moisture content is less than or equal to 20 percent) is easy to adhere to the inner wall of a crushing cavity when crushed, so that the residual quantity of coal samples is high, the crushing granularity precision is affected, and the cross contamination of the next coal blending is caused; 3. The water control precision is low, the water adding amount is required to be calculated manually after the water in the traditional coal blending is detected, the adjustment is lag, the error is large, and the uniform mixing effect of the coal sample and the subsequent coking quality are affected; 4. the mixing risk is prominent, namely a mixing device is not thoroughly cleaned, leading coal samples are easy to remain when different formula coal samples are switched, and the proportion deviation of coal blending is caused; 5. the data consistency is poor, namely, each device independently operates, the data such as coal sample information, device parameters and the like cannot be communicated in real time, and the tracing and intelligent management of the coal blending process are difficult to realize; 6. the efficiency bottleneck is obvious, the moisture detection needs to occupy the system waiting time, the subsequent coal samples cannot be processed in parallel, and the overall process is not smooth.
