10. A method for coking coal blending equipment according to any one of claims 1 to 9, characterized in that: The method of the coking coal blending equipment comprises the following steps: Step 1: Coking coal blending materials are added into the coal blending box (1) from the feed inlet (2), and the driving motor 3 (73) is rotated to drive the rotating roller (71) to rotate, and the rotating roller (71) drives the material leveling rod (72) to rotate, so that the materials entering the feed inlet (2) are stirred by the material leveling rod (72) and scattered to various places of the filter screen (11) in the coal blending box (1), so as to avoid the accumulation of raw materials affecting the filtering efficiency; Step 2: The filter screen (11) performs filtering, the telescopic member (9) extends to drive the push plate (10) to move, the push plate (10) pushes the material that cannot be filtered to the guide cylinder (6), and the larger particles of coking coal fall from the guide cylinder (6) to the middle of the crushing roller (54) for crushing, the driving motor 2 (553) rotates to drive the gear 1 (551) to rotate, the gear 1 (551) drives the gear 2 (554) to rotate, the crushing roller (54) where the gear 2 (554) is located rotates, the crushing roller (54) crushes the larger coking coal, and the connecting frame (581) is pulled up to extend the damping telescopic rod (582) The interception net (583) extends from the crushing box (51) and is intercepted by the interception net (583) to avoid the splashing of debris caused by crushing and protect the processing environment. When it is necessary to crush the coking coal into particles of different specifications, the forward and reverse threaded screws (57) are rotated to adjust the spacing between the two sliders (56), thereby adjusting the distance between the crushing rollers (54) so ​​that the coking coal can be crushed into particles of different specifications and led out of the crushing box (51) to a unified collection point for collection. The larger particles of coking coal screened out can be directly crushed again, reducing the transfer process and time, thereby promoting a higher efficiency in coking coal blending; Step 3, the filter (11) filters and screens the generated dust, the exhaust fan (32) rotates to suck the dust, the dust enters from the collection cover (31), is transported by the exhaust tube (39) and the delivery pipe (33), and the gas is discharged from the spherical exhaust cover (36). The adsorption liquid in the dust box (34) adsorbs the dust in the gas, and the dust is precipitated. The precipitate is discharged from the sewage outlet (37). The gas is filtered through the dustproof net (353) and then discharged to avoid residue and reduce air pollution. The filter rack (352) is pulled out, and the surface of the dustproof net (353) is cleaned to avoid clogging and affecting the filtering effect. The adsorption liquid is added to the dust box (34) through the mounting seat (355); Step 4: The coking coal material filtered by the multi-layer filter screen (11) falls down and is collected by the discharge plate (42), so that the coking coal material is gathered in the arc tube (46). The driving motor (41) rotates to drive the spiral conveying roller (45) to rotate. The spiral conveying roller (45) conveys the material to one end of the side tube (43). The coking coal material is discharged from the discharge port (44). The discharge is stable and avoids blockage.
