Description
Technical field
The invention belongs to coal slime dewatering technical fields, and in particular to a kind of coal slime filter aid chemicals dosing plant.
Background technique
Dehydrating floatation coal processing is to realize the important link of closed water circuit in coal preparation plant, this is beneficial to protection ring
Border is increased economic efficiency.Since floating tail-coal has the characteristics that fine size, viscosity are big, clay mineral is more, lead to coal slime dewatering ring
It is low to save rate of water loss, influences enterprise's production.Meanwhile higher filter cake moisture will cause water resource waste, transportation cost increases, storage
It is big etc. to transport difficulty.During coal slime dewatering, prior art and equipment can not changed using the method for addition filter aid
Under the premise of improve dehydrating effect, there is simple, quick, at low cost, quick advantage, thus receive extensive research and answer
With.
It before coal slime dewatering, generally requires and ore pulp is pre-processed, main includes concentration, dosing of sizing mixing.Ore pulp is dense
After contracting, concentration, which can be improved, is greater than 400g/L, and pulp viscosity is big in addition, therefore, even if by general mixed method very
High sizes mixing under speed of agitator, it is also difficult to adequately be mixed filter aid with ore pulp.Filter aid mixing is uneven, can reduce
Its drainage efficiency, influences the dehydration efficiency of coal slime, while also resulting in the waste of filter aid.
Summary of the invention
The purpose of the present invention is to provide one kind to be sufficiently mixed filter aid and ore pulp, improves drainage efficiency, meanwhile,
Reduce the filter aid chemicals dosing plant for stirring energy consumption of sizing mixing.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of coal slime filter aid chemicals dosing plant, including feed pipe, ore pulp bucket, motor, impeller-agitator, partition, hole of being used as medicine,
Medicament chamber, the pipeline that is used as medicine, variable frequency pump, discharge nozzle, granularity and partial size detector, Pulp pump, controller, the impeller-agitator position
In on ore pulp bucket central axes, with discharge nozzle in the same horizontal position；The medicament chamber is located at below ore pulp bucket, passes through partition and mine
Slurry bucket separates, and medicament is added in ore pulp by equally distributed hole of being used as medicine on partition.
The impeller-agitator is driven by a motor, and its stirring intensity only needs to guarantee that nearby ore pulp and medicament mix impeller layer
It closes uniform.
The medicament chamber is connected with the pipeline that is used as medicine.
The Pulp pump is mounted on discharge nozzle.
The variable frequency pump, which is installed on, to be used as medicine on pipeline, can be by changing frequency come the additional amount of regulating agent.
The controller controls the frequency of variable frequency pump by the data that processing granularity and partial size detector are sent, to control
Dosage processed.
The granularity and partial size detector are installed on discharge nozzle, it can be achieved that partial size and grain number to particle in ore pulp carry out
Prolonged real-time, online in situ measurement, the particle size range for measuring particle is 0.5-1000 μm.
The beneficial effects of the present invention are:
(1) cooperate impeller stirring that filter aid is enable quickly to be sufficiently mixed with ore pulp by equally distributed hole of being used as medicine,
Energy consumption of sizing mixing is reduced simultaneously；
(2) it is enabled devices to by the automatic system that granularity and partial size detector, controller, variable frequency pump are constituted according to discharging
The property of pipe ore pulp carrys out real-time regulating agent additive amount, avoids the situation that dosage is insufficient or excessive.
Detailed description of the invention:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the medicament pore size distribution figure on partition of the present invention；
Specific embodiment
In conjunction with Fig. 1 to Fig. 2, the present invention is described further.
A kind of coal slime filter aid chemicals dosing plant, including feed pipe 1, ore pulp bucket 2, motor 3, impeller-agitator 4, partition 5, enter
Medicine hole 51, medicament chamber 6, the pipeline 7 that is used as medicine, variable frequency pump 8, discharge nozzle 9, granularity and partial size detector 10, Pulp pump 11, controller
12, the impeller-agitator 4 is located on 2 central axes of ore pulp bucket, with discharge nozzle 9 in the same horizontal position；The medicament chamber 6 is located at
2 lower section of ore pulp bucket, is separated, and medicament is added by equally distributed hole 51 of being used as medicine on partition 5 by partition 5 and ore pulp bucket 2
Into ore pulp.
The impeller-agitator 4 is driven by motor 3, and its stirring intensity only needs to guarantee impeller layer nearby ore pulp and medicament
It is uniformly mixed.
The medicament chamber 6 is connected with the pipeline 7 that is used as medicine.
The Pulp pump 11 is mounted on discharge nozzle 9.
The variable frequency pump 8, which is installed on, to be used as medicine on pipeline 7, can be by changing frequency come the additional amount of regulating agent.
The controller 12 controls the frequency of variable frequency pump 8 by the data that processing granularity and partial size detector 10 are sent,
To control dosage.
The granularity and partial size detector 10 are installed on discharge nozzle 9 partial size and grain number, it can be achieved that particle in ore pulp
Prolonged real-time, online in situ measurement is carried out, the particle size range for measuring particle is 0.5-1000 μm.
