Abstract
A pipeline coal slurry preprocessing device is provided, which belongs to a field of coal slurry preprocessor for coal washery floating and feeding, and comprises a flotation agent emulsator and a pipeline mixer. Wherein, the flotation agent emulsator is positioned on a feeding pipeline between a feeding pond and a feeding pump; the pipeline mixer is arranged on the coal slurry pipeline in between a flotation machine and the feeding pump. Compared with the existing technology, the device has good dispersing and mixing effect, simple equipment and small bulk; in addition, the device features small maintenance workload without adding with outer power and is unnecessary of occupying a single factory building and requiring a certain factory building height, thus saving the energy and lower the overall construction cost of coal washery.
Description
Technical field
The utility model relates to the coal paste preprocessor of a kind of coal preparation plant floatation feed, specifically the Pipe Type Coal Slurry Pre-treater that is combined by flotation agent emulsifier and pipe-line mixer.
Background technology
The floatation feed pretreatment unit of China coal preparation plant employing at present has agitator, kaskad apparatus for pre-flotation pulp conditioning, coal paste preprocessor, falls case etc., and all there is following shortcoming in these pretreatment units:
1, be vertical and all need specific sling height, so not only need certain floor space, and all corresponding raising of workshop factory building height, thereby the investment of founding the factory increased;
2, all need additionaling power;
3, all there are the different defective of degree in the dispersion of flotation agent and the mixing of floatation feed.
Summary of the invention
Goal of the invention of the present utility model is the defective at prior art, a kind of dispersion, good mixing effect is provided, does not need additionaling power, does not have specific sling height to require, do not need the independent Pipe Type Coal Slurry Pre-treater that takies plant area.
Realize the foregoing invention purpose by the following technical solutions: a kind of coal slurry pretreatment unit, it is characterized in that, described coal slurry pretreatment unit is made up of flotation agent emulsifier and pipe-line mixer, this flotation agent emulsifier is installed on the pan feeding pipeline between pan feeding pond and the pan feeding pump by pipeline, and described pipe-line mixer is installed on the coal slurry pipeline between flotation device and the pan feeding pump.
Owing to adopted technique scheme, flotation agent emulsion earlier is delivered to pipe-line mixer through pan feeding impeller of pump strong agitation and pipeline hydraulic turbulent flow and sends into flotation device, compared with prior art, dispersion and good mixing effect, equipment is simple, volume is little, do not need additionaling power, maintenance load is little, do not need independent plant area and the specific requirement on height of workshop of taking, thereby can save the energy, reduce the whole construction cost of coal preparation plant.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the utility model flotation agent emulsifier structural representation.
Fig. 3 is the utility model pipe-line mixer structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1, the utility model coal slurry pretreatment unit is made up of flotation agent emulsifier 4 and pipe-line mixer 2 two parts.Pipe-line mixer 2 is installed on the coal slurry pipeline 3 between floatation feed pump 8 and the flotation device 1, long 2100～3300mm, and diameter is 300～600mm.Pipe-line mixer 2 one ends are connected with flotation device 1, and the other end is that the pan feeding pipeline is connected with pan feeding pump 8 discharging openings by coal slurry pipeline 3, and the feeding mouth of pan feeding pump 8 is connected with pan feeding pipeline 7, and pan feeding pipeline 7 is connected with pan feeding pond 6.The pipeline 5 of flotation agent emulsifier 4 communicates with pan feeding pipeline 7.Flotation dilution water pipeline (being with electronic adjusting gate valve) joins with pan feeding pipeline 7.
Referring to Fig. 2, flotation agent emulsifier 4 adds funnel 15, water injection emulsifier 12, Pressure gauge 9, vacuum meter 11 etc. by ultrasonic flowmeter 17, flotation agent and forms.Flotation agent of the present utility model is collecting agent and foaming agent.Ultrasonic flowmeter (SCL-61 type) 17 1 ends that are used to measure the instantaneous delivery, integrated flow, cumulative time etc. of collecting agent, foaming agent are communicated with collecting agent, foaming agent storage device, the other end is added into funnel 15 with pipeline and flotation agent and is communicated with, and pipeline is provided with collecting agent, foaming agent addition control valve 16.The delivery outlet that flotation agent adds funnel 15 is connected with water injection emulsifier 12 by the flotation agent output pipe that valve 14 is installed, water sprays on the emulsifier 12 nozzle 19 is housed, nozzle 19 is provided with the commentaries on classics heart valve 18 that is used to clear up the blocked nozzle of possibility, and nozzle 19 is connected with inlet pipeline 10.Be equipped with on the inlet pipeline 10 and be used to measure the Pressure gauge (0～0.4Mpa) 9 that water sprays emulsifier 12 operating pressures.Water sprays also installs a vacuum meter that is used to measure negative pressure in it (0～-0.1Mpa) 11 on the emulsifier 12.The efferent duct that water sprays emulsifier 12 is connected with emulsion outlet 20, and the connecting portion of efferent duct and emulsion outlet 19 is provided with closed cover 13.The function of flotation agent emulsifier is that the floating agent such as the dispersion granulating such as kerosene, light diesel fuel that utilize the water ejector principle to be difficult for disperseing in water directly are the fine drop of 5～15 μ m.
Referring to Fig. 3, pipe-line mixer 2 is the metal cylinders that can stand, crouch or tilt to install, and an end is connected with floatation feed pump 8, and the other end is connected with the flotation device feed box.Pipe-line mixer 2 is equipped with the unit that some groups of inclination angles are metallic plate composition 30～60 degree and that arrange according to the order of sequence in being.Its function is coal slurry and flotation agent emulsion to be stirred that it is mixed is more even.
The course of work of the present utility model: flotation agent (collecting agent and foaming agent) shows instantaneous delivery by ultrasonic flowmeter 17, adds up flow process and after the time, enters flotation agent funnel 15 by the road, enters water through funnel 15 and sprays emulsifier 12.Press water enters water by water inlet pipe 10 and sprays emulsifier 12, and to spray from water injection emulsifier 12 interior nozzles 19 at a high speed, water is sprayed form negative pressure in the emulsifier 12, because the shearing of negative pressure and high-velocity flow makes flotation agent emulsification, emulsion is through emulsion outlet 20 ejections.The coal slurry that carries flotation agent emulsion delivers into coal slurry pipeline 3 by pan feeding pump 8 and delivers to pipe-line mixer 2, because the effect coal slurry of metallic plate " unit " is in complete turbulence state, coal slurry and flotation agent emulsion further evenly are mixed into flotation device 1.
