Abstract
An iron ore concentrate conveying pipe is arranged between a concentration basin and an underflow pump, and includes an ore pulp pipe and a cleaning device used for cleaning scale deposit in the ore pulp pipe. The cleaning device includes a cleaning agent inlet pipe and a cleaning agent outlet pipe, wherein the cleaning agent inlet pipe is arranged at a pipe valve outlet of the ore pulp pipe, which is close to a discharge port of the concentration basin, and the cleaning agent inlet pipe is communicated with the ore pulp pipe; the cleaning agent outlet pipe is arranged at an inlet of the ore pulp pipe, which is close to the underflow pump, and the cleaning agent outlet pipe is communicated with the ore pulp pipe; and a cleaning agent can enter the ore pulp pipe through the cleaning agent inlet pipe, cleans away the scale deposit in the ore pulp pipe, and then flows out from the cleaning agent outlet pipe. The iron ore concentrate conveying pipe has the advantages that the pipe can be conveniently cleaned in time when scale deposits on the pipe, and the conditions that underflow pump flow is influenced by the deposit and the concentration basin is mired can be avoided.
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.
After the pipeline scale, fouling is very serious, and pipe diameter is diminished, and seriously reduces flow, has increased the load of underflow pump, thereby has reduced working life.
In actual production, because the continuity of production task, it is in service that urgency is in the underflow pump for a long time, flowing of ore pulp arranged in the pipeline at any time, slow from the flow rate of pulp that thickner flows out, added PH modifier does not have complete mixing in this section, thereby make this segment pipe be easy to fouling, this just need clean pipeline after operation a period of time, because this pipeline has adopted the mode of the using and the reserved, only need stop another continuation operation of a pipeline during cleaning, to be cleaned finishing done standby so that another pipeline comes into operation need clean the time, like this not influence production.
The existing mode that pipeline scale is cleaned is at pipeline not during transfer ore pulp, transporting water or washing agent wash pipeline, but owing to do not have special washing unit in the iron ore concentrate conveying pipeline, need remove equipment component during cleaning, clean time is long, cost is high.
The model utility content
The purpose of this utility model is to overcome the defective of above-mentioned prior art, a kind of novel iron ore concentrate conveying pipeline is provided, can carry out conveniently, clean timely pipeline scale, in order to avoid because scale effect underflow pump duty and cause deckered stock chest to run and mix, thereby influence is produced.
In order to achieve the above object, iron ore concentrate conveying pipeline of the present utility model, it is arranged on deckered stock chest between the underflow pump, comprises ore slurry pipeline and is used for cleaning the washing unit of the fouling of ore slurry pipeline.
Washing unit comprises washing agent inlet pipeline and washing agent outlet conduit, the washing agent inlet pipeline is arranged on the discharge port pipeline valve outlet port of ore slurry pipeline near deckered stock chest, be communicated with ore slurry pipeline, the washing agent outlet conduit is arranged on the inlet of ore slurry pipeline near the underflow pump, be communicated with ore slurry pipeline, washing agent enters in the ore slurry pipeline by the washing agent inlet pipeline, and the fouling in the ore slurry pipeline is cleaned, and washing agent flows out from the washing agent outlet conduit then.
Be provided with valve on washing agent inlet pipeline and the washing agent outlet conduit.
Washing unit also comprises washery pump, purge tank and the washing agent pipeline that is communicated with the washing agent inlet pipeline, and washery pump is extracted into the washing agent in the purge tank in the ore slurry pipeline by washing agent pipeline, washing agent inlet pipeline.
The washing agent inlet pipeline is connected by rapid pipe joint with the washing agent pipeline.
The washing agent pipeline adopts flexible pipe.
The other end of washing agent outlet conduit is communicated with described purge tank, and the washing agent from the washing agent outlet conduit flows out flows in the purge tank.
Iron ore concentrate conveying pipeline of the present utility model behind pipeline scale, can carry out conveniently, clean timely pipeline, has avoided because scale effect underflow pump duty and cause deckered stock chest to run the situation of mixing.
Description of drawings
Fig. 1: the utility model iron ore concentrate conveying pipeline schematic representation.
Figure acceptance of the bid mark: 1, deckered stock chest; 2, the discharge port pipeline valve of deckered stock chest; 3, ore slurry pipeline; 4, washing agent inlet pipeline; 5, the rapid pipe joint of belt switch; 6, washing agent pipeline; 7, washing agent pump; 8, cleaning agent tank; 9, washing agent outlet conduit; 10, underflow pump
Embodiment
As shown in Figure 1, ore slurry pipeline 3 upper sheds welding washing agent inlet pipeline 4 in discharge port pipeline valve 2 outlet ports of deckered stock chest 1, washing agent inlet pipeline 4 is provided with the rapid pipe joint 5 of a belt switch, one end of washing agent pipeline 6 can be connected with the rapid pipe joint 5 of belt switch, the other end is connected with washing agent pump 7, at the ore slurry pipeline 3 upper sheds welding washing agent outlet conduit 9 near underflow pump 10 ingress, the other end of washing agent outlet conduit 9 is communicated with lotion jar 8.When cleaning, needs close the discharge port pipeline valve 2 of deckered stock chest, washing agent pipeline 6 is received in the rapid pipe joint 5 of belt switch, install certain alkaline metal cleaner with cleaning agent tank 8, with washing agent pump 7 washing agent is extracted in the ore slurry pipeline 3 by washing agent pipeline 6, washing agent inlet pipeline 4, fouling in the ore slurry pipeline 3 is cleaned, washing agent flows back in the cleaning agent tank 8 by washing agent outlet conduit 9 then, so continuous circuit cleans ore slurry pipeline 3, and concrete clean time is grasped flexibly according to the thickness of fouling.
