Abstract
Provided is a heavy-medium coal slurry recycling system. A centrifugal liquid discharging pipe of a middings coal horizontal dehydration device is communicated with a first section of a concentrated tank. The first section of the concentrated tank is simultaneously communicated with a flocculant storage groove, and the first section of the concentrated tank is connected with a second section of the concentrated tank in series. The heavy-medium coal slurry recycling system improves productivity of middings coal, ash content of the coal slurry is improved compared with the original coal slurry, and circulation water is cleaner than original circulation water.
Description
Technical field
The utility model belongs to technical field of coal chemical industry, relates in particular to the coal washing system.
Background technology
In coal crouch that to take off centrifugate be black water, centrifugate flows directly into two sections concentration basins, dispatches from the factory as coal slime through post precipitation, causes a part of fine particle cleaned coal to be lost in the coal slime, so coal slime ash split pole is low, has brought financial loss to coal separating plant.
The utility model content
The utility model problem to be solved provides heavily Jie coal slurry water recovery system in coal of coal productive rate in a kind of can the raising.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of heavy Jie's coal slurry water recovery system in coal, the middle coal centrifugate vent pipe that takes off for sleeping in is communicated with one section concentration basin, and one section concentration basin is communicated with the flocculation agent storage tank simultaneously, one section concentration basin and two sections concentration basins series connection.
Adopt the utility model to improve middle coal productive rate, the coal slime ash content has also improved than original, and recirculated water is also than original limpid simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, a kind of heavy Jie's coal slurry water recovery system in coal, middle coal crouches and to take off 1 centrifugate vent pipe 2 and is communicated with one section concentration basin 3, and one period 3 while of concentration basin is communicated with flocculation agent storage tank 4, and one section concentration basin 3 and two sections concentration basins 5 are connected.
In the coal nest take off centrifugate and flocculation agent adds in one section concentration basin simultaneously, make centrifugate force rapid precipitation in advance, the coal measures system dispatches from the factory after dewatering in the entering, enters into product of coal to original part coal slime.
Claims (1)
1. coal slurry water recovery system in coal that heavily is situated between is characterized in that: the middle coal centrifugate vent pipe that takes off that crouches is communicated with one section concentration basin, and one period concentration basin while is communicated with the flocculation agent storage tank, and one section concentration basin and two sections concentration basins are connected.
