Abstract
The utility model provides an iron ore concentrate transport pipeline disposed between a concentration pool and an underflow pump, the iron ore concentrate transport pipeline comprises an ore slurry pipeline (1) and a lime milk pipeline (2) connected to the ore slurry pipeline (1), the lime milk pipeline (2) is inserted into the ore slurry pipeline (1). The tube wall of the part that the lime milk pipeline (2) inserting the ore slurry pipeline (1) is provided with a plurality of hoes. The lime milk pipeline (2) is provided with a check valve (3). The lime milk pipeline (2) adopts a metal wear-resistant tube. The iron ore concentrate transport pipeline adopts the metal wear-resistant punching short tube to insert into the ore slurry pipeline when the lime milk pipeline enters the ore slurry pipeline, in this way, the lime milk can smoothly reach the middle bottom part of the pipeline when entering the ore slurry pipeline instead of flowing along the tube wall, making the lime milk liquor uniform when entering the ore slurry pipeline, generating turbulent flow without scaling.
Description
Technical field
The utility model relates to long-distance iron ore concentrate conveying pipeline, relates to a kind of deckered stock chest specifically to the iron ore concentrate conveying pipeline between the underflow pump.
Background technique
" long-distance iron ore concentrate pipeline conveying " is emerging, new high-tech industry, is the bright spot of low-carbon (LC), green economy.It is 62%～68% that the long-distance slurry line transportation requires slurry concentration, and this low density ore pulp that just requires ore pulp to need the ore dressing plant is provided before entering pipeline is concentrated to technological requirement and carries.
And arrive the pipeline between the underflow pump because flow velocity is slower at deckered stock chest, and need add lime milk solution adjusting PH at this segment pipe, this just makes this segment pipe be easy to fouling, and influence is produced.
Existing lime milk pipeline enters the main pipe place and directly receives on the main pipe, this just makes lime milk can not well arrive the bottom when entering main pipe, deckered stock chest is relatively slow to flow velocity between the underflow pump in addition, this just makes constantly fouling on tube wall between ore pulp and the lime milk, thereby influence is produced.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of novel iron ore concentrate conveying pipeline is provided, and has effectively solved the problem of deckered stock chest to the easy fouling of iron ore concentrate conveying pipeline between the underflow pump.
In order to achieve the above object, iron ore concentrate conveying pipeline of the present utility model comprises ore slurry pipeline and the lime milk pipeline of receiving on the ore slurry pipeline, and the lime milk pipeline extend in the ore slurry pipeline.
The lime milk pipeline extend on the tube wall of the part in the ore slurry pipeline and is equipped with a plurality of holes.
The lime milk pipeline is provided with safety check.
The lime milk pipeline adopts the abrasion-resistant metal pipe.
The utility model adopts abrasion-resistant metal punching short tube to extend in the ore slurry pipeline when the lime milk pipeline enters ore slurry pipeline, just can arrive the middle bottom of pipeline so very smoothly when lime milk enters ore slurry pipeline, rather than flow along tube wall.Make when lime milk solution enters into ore slurry pipeline evenly, produce turbulent flow and non-scaling.

Description of reference numerals: 1, ore slurry pipeline; 2, lime milk pipeline; 3, safety check.
Embodiment
As shown in Figure 1, lime milk pipeline 2 extend in the ore slurry pipeline 1, and is equipped with a plurality of holes on lime milk pipeline 2 extend into the tube wall of the part in the ore slurry pipeline 1, makes when lime milk solution enters into ore slurry pipeline evenly, produces turbulent flow and non-scaling.
