Coal tar pretreatment equipment in coal tar hydrogenation process

The utility model relates to coal tar pretreatment equipment in a coal tar hydrogenation process. Supporting table, a support frame is fixedly welded on the support table; a spiral crushing blade, a stirring rod, a heating sleeve, a conical filtering net frame and a filtering box are arranged; coal tar crushing device, crushing and directly heating to obtain liquid; the pumping amount of the coaltar is uniform; facilitating hydrogenation reactions of coal tar, coal tar treated by the coal tar pretreatment equipment does not cause blockage of a fixed bed delivery pump; coal tar conversion rateis high, improving work efficiency, meanwhile, the water spraying head is arranged, the conical filter screen frame and the interior of the barrel body are convenient to clean; meanwhile, by arranging a first gear roller and a second gear roller, coal tar filtered on the conical filter screen frame can be effectively subjected to secondary crushing treatment, waste of raw materials can be effectively reduced, and by arran
