Abstract
A kind of short circle pipe-line system regulating pulp concentration, belong to and carry the technical field of object with fluid flowing or pressure by pipeline or pipe, it is characterized in that, one meter, downstream being positioned at flowmeter on ore slurry pipeline, also be relative ground level 6 meters of, the threeway that a bore specification is identical with ore slurry pipeline bore is installed, the import of the control valve of dimension is communicated with the central exit of this threeway, then the system conduit entrance of short circle system is exported with control valve is connected.Shutoff is carried out to former lesser circulation pipeline access point position.Operating platform is reset in new access point position.
Description
One, art
Belong to the technical field of ore slurry pipeline conveying, relate to a kind of circulatory system, especially a kind of short circle pipe-line system that can regulate pulp concentration.
Two, background technique
Lesser circulation is a kind of device that PSI (pipeline company of the U.S.) design is used for regulating pulp concentration.When ore deposit is come after thickner is concentrated in Ba Run ore dressing plant, when concentration does not reach technological requirement, by underflow pump, the iron ore concentrate slurry bottom deckered stock chest is promoted back deckered stock chest and carry out secondary concentration.
According to the design of PSI, the position of short circle pipeline access point is positioned at stirring chest top, relative ground level is 17 meters, there are three problems in this set: 1, when needs carry out short circle operation, post personnel need arrive stirring chest top and operate, and top operational limited space, work together very inconvenient; Simultaneously because operating platform is higher, considerably increase the labor intensity of employee.2, stirring chest enters pipe and differs less with lesser circulation pipeline elevation, when carrying out ore deposit concentration and being defective, is still in highly energy-consuming state when underflow pump beats short circle.3, lesser circulation pipe wear is serious, just needs process leak source per fortnight once, within every two months, just needs to change pipeline once.
Three, summary of the invention
The object of the invention is the deficiency existed for overcoming former lesser circulation, the utility model, under the prerequisite not changing technique, by rationally determining the position of short circle pipeline access point, reaching energy-saving and cost-reducing, reducing the object of pipe wear.
Former lesser circulation pipeline occurs that the basic reason of above-mentioned three problems is that the position of lesser circulation pipeline access point is unreasonable.As long as rationally determine short circle pipeline access point position, after also namely reducing the height of lesser circulation pipeline and control valve, the problems referred to above can be readily solved.The technical solution of the utility model is achieved in that, 1 meter, downstream being positioned at flowmeter on ore slurry pipeline, also be relative ground level 6 meters of, the threeway that a bore specification is identical with ore slurry pipeline bore is installed, the import of the control valve of dimension is communicated with the central exit of this threeway, then lesser circulation conduit entrance is exported with control valve is connected.Shutoff is carried out to former lesser circulation pipeline access point position.Operating platform is reset in new access point position.
Effect after the utility model enforcement is as described below: first, do not use stirring chest top after the height reduction of lesser circulation control valve to operate, valve location after reduction is set for this platform and is operated, and both can increase operating space, also can reduce staff labor intensity.Secondly, because short circle pipeline access point position reduces, can operation frequency be reduced when underflow pump beats short circle, be in low power consuming state.Finally, because short circle pipeline and stirring chest enter ore deposit pipeline enclosure depth displacement enough greatly, lesser circulation pipeline is in full-section pipe-flow state always, and velocity in pipes is moderate, fluid stable, and pipe wear is corresponding to be alleviated.
After the utility model is implemented, never there is worn out leakage accident in lesser circulation conduit running, saves a large amount of spare part and maintenance expenses so far, and the frequency that underflow pump beats short circle is reduced to 32 ~ 35Hz by 38 original ~ 41Hz, reduces energy consumption.
Four, accompanying drawing explanation
Fig. 1 is the utility model positional structure schematic diagram
1-threeway in figure, 2-lesser circulation pipeline, 3-short circle control valve, 4-operating platform, 5-flowmeter, 6-densitometer, 7-deckered stock chest, 8-stirring chest, 9-ore slurry pipeline, 10-underflow pump.
Four, embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment 1
Ore slurry pipeline (9) is positioned at, 1 meter, downstream of flowmeter (5), also be relative ground level 6 meters of, the threeway (1) of a DN300 is installed, the lesser circulation pipeline (2) identical with this threeway (1) bore is connected to the neutral position of this threeway (1) by lesser circulation control valve (3), the two ends of DN300 threeway (1) are connected with ore pulp delivery duct (7) respectively.Shutoff is carried out to the pipeline opening of former lesser circulation pipeline (2) access point position.Operating platform (4) is reset, as shown in Figure 1 in new access point position.
By observing the real time data of monitoring stream gauge (5), densitometer (6), judging ore pulp state, determining entered stirring chest (8) or be back to deckered stock chest (7).When pulp concentration meets technological requirement in deckered stock chest (7), enter stirring chest (8) by underflow pump (10) through ore slurry pipeline (9).When in deckered stock chest (7), pulp concentration does not meet technological requirement, open lesser circulation control valve (2), be back to deckered stock chest (7) through ore slurry pipeline (7) and lesser circulation pipeline (2) and continue concentrated until concentration meets technological requirement.
The utility model both reduced staff labor intensity, alleviated pipe wear again, also achieved energy-saving and cost-reducing object after implementing.
