In order to overcome the deficiencies in the prior art, technical scheme of the present invention solves like this:
Long distance convey coal pipe head end black water pulping system device, comprise thickner, sewage work, black water stirred pot, coal pulverizer, coal yard, crusher, buffering coal bin, Weighing feeder, manage defeated coal slurry stirred pot, special character of the present invention is that described thickener overflow one end is connected with described sewage work by pipeline, described thickener underflow one end is connected with described black water stirred pot top by a pump and pipeline, described black water stirred pot bottom is connected with described coal pulverizer feeding mouth by two pumps and pipeline, described coal yard is connected with described crusher feeding mouth by a rotary conveyor, described discharge hole of crusher is connected with described buffering coal bin feeding port by No. two rotary conveyors, described buffering coal bin feed opening is connected with described Weighing feeder feeding end, described Weighing feeder discharge end is connected with described coal pulverizer feeding mouth, described coal pulverizer discharge port is connected with the defeated coal slurry stirred pot of described pipe.
A head end black water pulping process for described device, carries out successively in the steps below:
1), containing fine grain black water after thickner is concentrated, thickener overflow by Cemented filling to sewage work, thickener underflow by a pump and Cemented filling in black water stirred pot;
2) underflow, be stored in black water stirred pot enters coal pulverizer feeding mouth through two pumps and pipeline;
3), the lump coal that is stored in coal yard forms fine coal after entering crusher coarse crushing by a rotary conveyor, and fine coal sends into buffering coal bin feeding port buffer storage by No. two rotary conveyors;
4), fine coal after Gravimetric Coal Feeders Weighing, enters coal pulverizer feeding mouth from the releasing of buffering coal bin feed opening;
5), the lump coal breaking fine coal and the black water that become after coal pulverizer grind, enter from the gravity flow of coal pulverizer discharge port and manage the storage of defeated coal slurry stirred pot.
The beneficial effect of long distance convey coal pipe head end black water pulping system device: effects on slurry making is good, energy consumption is low, the direct mixed grinding slurrying of lump coal after utilizing the black water of coal separating plant and dewatering, decrease the middle-chain of being dewatered further by black water, by controlling concentration and the flow of black water and adopting Gravimetric Coal Feeders Weighing fine coal weight, effectively can control the concentration of coal pulverizer coal slurry product, apparatus structure is simple, easy to install, be widely used in long-distance pipeline coal industry.
