Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-ecp cylinder, 2-disperse bucket, 3-overflow launder, the 4-guide rod, 5-slime separation chamber, the horizontal nozzle of 6-, the 7-distribution plate, 8-pressure water tank, 9-embolism valve seat, 10-embolism valve, 11-nozzle, 12-density sensor, 13-hang plate group, 14-blowoff valve, 15-PLC electric-control system, the 16-feed pipe, the outlet of 17-cleaned coal, 18-technology clear water inlet.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises the slime separation chamber, it is characterized in that: the dispersion bucket 2 of a band tangential feed pipe 16 is arranged at the top of described slime separation chamber 5, pass the center that disperses bucket 2, a guide rod 4 is arranged, its upper end links to each other with ecp cylinder 1, the lower end links to each other with embolism valve 10, in the separation chamber 5, also be provided with overflow launder 3, distribution plate 7, nozzle 11, density sensor 12 and hang plate group 13, wherein, density sensor 12 links to each other with electric-control system 15, nozzle 11 places on the distribution plate 7 and with pressure water tank 8 and links to each other, and hang plate group 13 places the top of separation chamber 5, and 3 of overflow launders that are positioned at top periphery export 17 with cleaned coal and are connected.
Described hang plate group 13 is along the circle distribution in the separation chamber 5.
Described distribution plate 7 is distribution plates that are back taper.
Concentrate coal slime slurry (concentration is 45-50%) and enter dispersion bucket 2 by tangential feed pipe 16, make it to be scattering into equably in the separation chamber 5, be beneficial to the sorting of coal slime and slow down disturbing the impact of bed, disperse the barrel top cover center that the ecp cylinder 1 and the guide rod 4 of 10 actions of control embolism valve are installed, embolism valve 10 is the main thoroughfares of discharging underflow, underflow control is a cover automatic control system, under in the separation chamber, the offset that the comparison signal of following two density sensors 12 produces, the current signal that is sent 4-20mA by PLC electric-control system 15 makes controller pass to 1 action of ecp cylinder, drive the 10 continuous opening and closing of embolism valve by guide rod 4, cause and disturb the sorting layer to be in a good stable state, the spoil that is deposited on the bottom is discharged, on float on end face cleaned coal discharge through overflow launder 3 and cleaned coal outlet 17.Cleaned coal is along with floating to separation chamber's end face on the ascending current, come together in the overflow launder 3, this will greatly improve the disposal ability of equipment, be arranged at 6 groups of hang plate groups 13 on separation chamber top, every group of hang plate is parallel and equidistant, the spoil that is mingled in the come-up cleaned coal is further separated, thereby the ash content in the cleaned coal is reduced, distribution plate 7 places the bottom of separation chamber 5, more than 400 nozzle is installed on it, be back taper, current from the nozzle ejection during work form a desirable interference fluid bed, make coal slime obtain sufficient sorting, in continuous interference assorting room, density is little, be not enough to overcome and float to the top on the material (cleaned coal) of water resistance and water buoyancy and overflow, and density is big, material (spoil) with big sinking speed then falls to the separation chamber bottom downwards, discharge after embolism valve 10 is opened, therefore, the power of injection water is to regulate the desirable key factor of disturbing fluidized-bed layer.To be the technology clear water that will have a 0.25-0.4MPa enter the pressure water tank 8 of separation chamber 5 bottoms dispersedly by three arms in the sorting water filling, and supply nozzle produces the water source that sprays, and injection flow can be regulated the requirement of sorting according to the user.The slime separation machine operation does not need the post driver, the black water of a certain coal has been debugged operational factor after, needn't change during ordinary production, the adjustment of separation chamber's internal density gradient is self-regulating by the PID closed-loop system.After ascending current speed is adjusted to a suitable numerical value and is full of separation chamber, just can begin charging, carry out ordinary production, have only when stable state is destroyed, just need reset the control parameter, in order to reach the setting value that separating effect can change controller.During normal the operation, the situation that only needs to observe cleaned coal overfall and discharge refuse mouth is by observing spillway discharge and reduce and the flow of discharge refuse stone obviously increasing and enriching, just indicating that the nozzle on the distribution plate may be blocked, the back water flushing that needs to stop, blowoff valve 14 can be used for blowdown as required.
