The demagnetizing system can effectively demagnetize the magnetic iron ore slurry, and can prevent the magnetic agglomeration of the magnetic ore slurry inside the pipeline from causing the blockage of the pipeline.
Description
Technical field
The present invention relates to a kind of complex-terrain long-distance iron ore concentrate ore slurry pipeline transportation art, especially a kind of iron ore concentrate pipeline multi-level demagnetizing system that relates to.
Background technique
In present Slurry Pipeline Transportation, bring certain magnetic can for the iron ore concentrate ore pulp owing to iron ore concentrate ore-dressing technique (low intensity magnetic separation, high intensity magnetic separation etc.) and in the long-distance pipe course of conveying.And starch conveyance conduit for the complex-terrain long-distance iron ore is not allow the iron ore slurry to have stronger magnetic, in case otherwise in course of conveying pipeline fault stop, will be when ore pulp is in not flowing state owing to magnetic forms magnetic coagulation, make particle chap, deposition and cause the serious obstruction of pipeline in pipeline very easily, cause to production to have a strong impact on or bring heavy economic losses to enterprise.
Summary of the invention
The present invention has designed a kind of complex-terrain long-distance iron ore concentrate ore slurry pipeline multi-level demagnetizing system, the technical problem of its solution is after the bigger ore pulp of carrying magnetic enters in the long-distance pipe, ore pulp in pipeline is because external cause when being in not flowing state, magnetic coagulation takes place easily, finally formation is rolled into a ball in conveyance conduit, cause conveyance conduit to stop up, finally influence defectives such as ordinary production.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of complex-terrain long-distance iron ore concentrate ore slurry pipeline multi-level demagnetizing system, comprise thickner, underflow pump and many pumping plants, the output terminal of described thickner is connected by pipeline with the input end of described underflow pump, described underflow delivery side of pump connects described many pumping plants by pipeline successively, is provided with demagnetizer on described thickner and described underflow pump connecting tube.
Further, also be provided with demagnetizer on the pipeline of adjacent two pumps station connection.
Further, the demagnetizer that is provided with of the pipeline that connects of adjacent two pumps station is positioned on the inlet pipe of pumping plant.
Further, described demagnetizer comprises coil, not magnetic conduction tube wall and high abrasion resisting material layer; Described coil is coated on the described not magnetic conduction tube wall, is provided with described high abrasion resisting material layer at described not magnetic conduction inner surface of tube wall.
This complex-terrain long-distance iron ore concentrate ore slurry pipeline multi-level demagnetizing system has following beneficial effect:
(1) the present invention can effectively take off magnetic with the iron ore slurry that has magnetic, and the magnetic coagulation phenomenon takes place in pipeline this ore pulp of just having avoided having magnetic, causes the line clogging problem.
(2) demagnetizer of the present invention is for working life of improving the demagnetizer pipeline and to preventing magnetic interference, the non-magnet material that adopts special material to make, and at inwall with high abrasion resisting material, can bring up to more than 5 years working life.

Embodiment
Below in conjunction with Fig. 1 and Fig. 2, the present invention will be further described:
A kind of complex-terrain long-distance iron ore concentrate ore slurry pipeline multi-level demagnetizing system, comprise thickner 1, underflow pump 3 and many pumping plants 4,7,10, the output terminal of described thickner 1 is connected by pipeline with the input end of described underflow pump 3, the output terminal of described underflow pump 3 connects described many pumping plants 4,7,10 by pipeline successively, is provided with demagnetizer 2 on described thickner 1 and described underflow pump 3 connecting tubes.
Also be provided with demagnetizer 6,9 on the pipeline that adjacent two pumps station connects.The demagnetizer 6,9 that the pipeline that adjacent two pumps station connects is provided with is positioned on the inlet pipe of pumping plant.
As shown in Figure 1, described many pumping plants are pumping plant 4, No. two pumping plants 7 and No. three pumping plants 10.Demagnetizer 6 is positioned on No. two pumping plant inlet pipes 5, and demagnetizer 9 is positioned on No. three pumping plant inlet pipes 8.
The whole system operation principle is as follows: described demagnetizer 2 is installed on the pipeline between thickner 1 bottom pipe and the described underflow pump 3, and the ore pulp that will carry is carried out taking off the first time magnetic.Described underflow pump mainly is to be transported to a described pumping plant 4 usefulness main pumps remote pressurized delivered is realized in the ore pulp back of pressurizeing taking off ore pulp behind the magnetic.Ore pulp is delivered to described No. two pumping plant inlet pipes 5, and the interior ore pulp of pipeline carried out for second step by described demagnetizer 6 and takes off magnetic, transferred out after the main pump pressurization by described No. two pumping plants 7 again; When ore pulp arrives described No. three pumping plant inlet pipes 8, carried out for the 3rd step by described demagnetizer 9 again and take off magnetic, take off ore pulp pressurized delivered behind the magnetic to the destination by 10 pairs of described No. three pumping plants.
The flow velocity of the interior ore pulp of pipeline is 0.5-1m/s between described thickner 1 and the underflow pump 3.
Described No. two pumping plant inlet pipes 5 and No. three pumping plant inlet pipe 8 interior flow rate of pulp are 1-2m/s.
As shown in Figure 2, described demagnetizer 2,6,9 comprises coil 11, not magnetic conduction tube wall 12 and high abrasion resisting material layer 13; Described coil 11 is coated on the described not magnetic conduction tube wall 12, is provided with described high abrasion resisting material layer 13 at described not magnetic conduction tube wall 12 internal surfaces.
