Abstract
The utility model relates to the defeated coal serous system device of cleaned coal slurrying pipe, adopt to mixing a fraction of pulverized coal grinding preparation defeated coal slurry of distance pipe of growing up in the cleaned coal mud after most coal separating plant's washing, removed from the cleaned coal slurry dewatering link after coal separating plant's washing; Meanwhile, also remove the broken link of feed coal prepared by the defeated coal slurry of long distance pipe from, significantly reduced energy consumption.The utility model device is mainly by constant feeder, cleaned coal hydraulic fill pipeline, premix steel basin, coal slurry pump, coal pulverizer, manage defeated coal slurry steel basin, online densitometer, under meter composition, constant feeder is connected with the top funnel mouth of premix steel basin, cleaned coal hydraulic fill pipeline is connected with the top of premix steel basin, the inlet flange of coal slurry pump is connected with the outlet at bottom flange of premix steel basin, the discharge flange of coal slurry pump is connected with the inlet flange of coal pulverizer, manage the top of defeated coal slurry steel basin and the outlet of coal pulverizer is connected, online densitometer and under meter are installed on cleaned coal hydraulic fill pipeline.
Description
Technical field
The utility model relates to the defeated coal serous system device of a kind of cleaned coal slurrying pipe, belongs to the defeated coal technical equipment of long-distance pipe field.
Background technology
The coal slurry weight concentration of long-distance transportation through pipeline is generally 50% to 60%, maximum particle size 3 millimeter, median size 0.3 millimeter.Cleaned coal mud weight concentration after coal separating plant's washing is generally 30% left and right, maximum particle size 0.5 millimeter, median size 0.1 millimeter.Before the utility model is made, the defeated coal slurry of long distance pipe all adopts the mixed head coal product of coal separating plant or more low-ash colliery raw coal to carry out slurrying, in pulping process, need feed coal fragmentation, grinding that the overwhelming majority is greater than to 3 millimeters, energy consumption is very high, simultaneously, cleaned coal mud after coal separating plant's washing need to further be dehydrated into cleaned coal mud and can be utilized, and the energy consumption of dehydration is also very high.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of cleaned coal slurrying pipe defeated coal serous system device, adopt to mixing a fraction of pulverized coal grinding preparation defeated coal slurry of distance pipe of growing up in the cleaned coal mud after most coal separating plant's washing, removed from the cleaned coal slurry dewatering link after coal separating plant's washing; Meanwhile, also remove the broken link of feed coal prepared by the defeated coal slurry of long distance pipe from, significantly reduced the energy consumption of above-mentioned two links.
For achieving the above object, the utility model is by the following technical solutions:
The defeated coal serous system device of cleaned coal slurrying pipe is mainly by constant feeder, cleaned coal hydraulic fill pipeline, premix steel basin, coal slurry pump, coal pulverizer, manage defeated coal slurry steel basin, online densitometer, under meter composition, described constant feeder is connected with the top funnel mouth of described premix steel basin, described cleaned coal hydraulic fill pipeline is connected with the top of described premix steel basin, the inlet flange of described coal slurry pump is connected with the outlet at bottom flange of described premix steel basin, the discharge flange of described coal slurry pump is connected with the inlet flange of described coal pulverizer, the top of the defeated coal slurry steel basin of described pipe is connected with the outlet of described coal pulverizer, described online densitometer and described under meter are installed on cleaned coal hydraulic fill pipeline.
The beneficial effect of the defeated coal serous system device of this cleaned coal slurrying pipe: when slurrying operation, concentration and flow that the coal dust amount of constant feeder records cleaned coal mud according to the online densitometer of cleaned coal hydraulic fill pipeline and under meter are adjusted in real time, be made into the defeated coal-water fluid concentration of suitable pipe, then ground to form the granularity that meets long-distance transportation through pipeline requirement by coal pulverizer; The cleaned coal mud of coal separating plant is directly processed into long-distance transportation through pipeline coal slurry, has significantly reduced the energy consumption of coal separating plant's cleaned coal slurry dewatering and two links of the long distance defeated slurrying of pipe; Whole apparatus structure is simple, easy to operate.
