Abstract
The invention discloses a double-impeller pulp self-pumping flotation machine, which radically solves the problem that the independent arrangement of a centrifugal sand pump is required when the suction travel of a first tank in next operation fails to meet the requirements of process configuration in the working process of the conventional pulp self-pumping flotation machine. The flotation machine comprises a tank body and a transmission mechanism assembled above the tank body, wherein the transmission mechanism drives the spindle of the transmission mechanism to rotate in a belt transmission mode, and the spindle is sleeved with a star impeller. The flotation machine has the key technical points that: the lower end of the spindle is assembled with a vertical centrifugal pump; an opening is formed below the pump shell of the centrifugal pump as a pump inlet; the lower end of the spindle passes through the pump shell, a pump wheel is sleeved in the pump shell, the outlet of the pump shell of the centrifugal pump is connected with a sand lift by a flange plate, and the sand lift is communicated to the first tank for next operation outside the tank body. The machine has the advantages of reducing infrastructure land and equipment investment, saving energy consumption, along with wide application range, safety, reliability, operation stability, high working efficiency and the like.
Description
Technical field
The present invention relates to a kind of coal preparation machine, belong to the floatation equipment technical field, the bilobed wheel self-pumping slurry type flotator that specifically a kind of valuable mineral that carries out according to the difference of various mineral surfaces physicochemical properties separates.
Background technology
At present, in enterprises such as ore dressing plant, coal preparation plant, one of important method that flotation sorts as mineral has been subjected to showing great attention to of mineral processing industries.In recent years, along with the appearance of efficient, energy-conservation, consumption reduction, low-carbon economy, people to researching and proposing of floatation equipment a lot of new problems---especially at different ore-dressing techniques, research and develop out the floatation equipment of the different ore-dressing techniques of adaptation.
In various types of flotation devices, self-priming flotation of ore pulp machine is applicable to the stern notch of flotation operation.But when the first groove suction Cheng Buneng of next operation satisfies the Process configuration requirement, to dispose Centrifugal Sand Pumps usually to mend its defective.Yet the independent configuration of Centrifugal Sand Pumps will inevitably bring the user to increase the new problem of equipment, power consumption, land occupation, increase investment.
Therefore, existing self-priming flotation of ore pulp machine still remains to be improved.
Summary of the invention
The objective of the invention is for a kind of bilobed wheel self-pumping slurry type flotator that has from pumping function is provided, fundamentally solve in the existing self-priming flotation of ore pulp machine course of work, when the first groove suction Cheng Buneng of next operation satisfies the Process configuration requirement, the problem of Centrifugal Sand Pumps need be set separately.
Technical scheme of the present invention is: this bilobed wheel self-pumping slurry type flotator, comprise cell body and be assembled in the transmission mechanism of cell body top, described transmission mechanism adopts belt transmissioning mode to drive its main axis rotation, suit star impeller on the described main shaft, its technical essential is: the lower end of described main shaft is equipped with a vertical centrifugal pump, described centrifugal pump pump case lower opening is as pump intake, described pump case is passed and suit pump impeller in pump case in described main shaft lower end, described centrifugal pump pump case outlet utilizes ring flange to connect sand lift, and described sand lift is communicated to the first groove of next outer operation of described cell body.
Described centrifugal pump pump case is spiral diffuser casing.
Described centrifugal pump pump case utilizes support to be fixed on described cell body bottom.
The blade of described pump impeller is provided with downwards.
Described star impeller top is provided with stator, and described stator top is provided with the current stabilization cover.
Advantage of the present invention and positive technique effect are: the present invention is equipped with a vertical centrifugal pump in its transmission main shaft lower end, and the main shaft lower end passes pump case and be set with pump impeller, then forms the two-wheel structure with the star impeller that is sleeved on equally on the main shaft.This two-wheel structure can help flotation device to be more suitable for stern notch as flotation operation, promptly when the first groove suction Cheng Buneng of next operation satisfies the Process configuration requirement, can the ore pulp of this operation be delivered to the first groove of next operation by this stern notch self-pumping ore pulp characteristic, and then can replace the Centrifugal Sand Pumps of setting separately.
Therefore the present invention possesses the investment that reduces capital construction soil, equipment, energy efficient, plurality of advantages such as applied widely, safe and reliable, stable, operating efficiency height.
Description of drawings
The invention will be further described in conjunction with the accompanying drawings:
Fig. 1 is a kind of concrete structure schematic diagram of the present invention;
Sequence number explanation among the figure: 1 drive pulley, 2 motor, 3 driven pulleies, 4 bearing bodies, 5 ore drawing valves, 6 supports, 7 spreading slurry tubes, 8 control valves, 9 pump impellers, 10 cell bodies, 11 pump cases, 12 main shafts, 13 star impellers, 14 stators, 15 current stabilization covers.
The specific embodiment
According to Fig. 1 the present invention is described in detail.
Bilobed wheel self-pumping slurry type flotator of the present invention comprises cell body 10 and is assembled in transmission mechanism of cell body 10 tops etc. that its transmission mechanism is identical with existing impeller self-priming ore pulp type flotation machine.Transmission mechanism adopts belt transmissioning mode to drive its main shaft 12 rotations, transmission mechanism mainly is made up of motor 2, drive pulley 1, driven pulley 3 etc., motor 2 drives drive pulley 1 rotation, drive pulley 1 drives driven pulley 3 again, driven pulley 3 and then 12 rotations of drive main shaft, main shaft 12 utilizes bearing body 4 to be bearing in cell body 10 tops.Main shaft 12 stage casing suit star impellers 13, star impeller 13 tops are provided with stator 14, and stator 14 tops are provided with current stabilization cover 15.Cell body 10 sides are provided with ore drawing valve 5.
As shown in Figure 1, it is constant that the present invention still keeps imitative Wei Muke type flotation machine prototype.Main improvement of the present invention is: the lower end of main shaft 12 is equipped with a vertical centrifugal pump, promptly main shaft 12 lower ends pass pump case 11 and in pump case 11 suit pump impeller 9, centrifugal pump pump case 11 utilizes support 6 to be fixed on cell body 10 bottoms, the blade of pump impeller 9 is provided with downwards.Pump case 11 lower opening of centrifugal pump are as pump intake, and the outlet of the pump case of centrifugal pump side utilizes ring flange to connect sand lift 7, and sand lift 7 other ends are communicated to the first groove of next outer operation of cell body.Centrifugal pump pump case 11 is set to spiral diffuser casing.
When transmission mechanism drove main shaft 12 rotations, the top flotation mechanism still kept the effect that efficiently sorts of prestige nurse material type flotation machine.Simultaneously, pump impeller 9 is with main shaft 12 rotations, because centrifugal action forms negative pressure in impeller cavity, ore pulp enters in the impeller cavity by pump intake in the groove.Ore pulp is discharged spiral (volute) delivery chamber enter pump case with certain speed from impeller periphery under the effect of blade, speed reduces then, and kinetic energy changes pressure into and can export into sand lift by pump case and deliver to next operation, reaches the purpose of pumping.
