Description

A kind of slurry memory storage with overflow precise monitoring function

Technical field

The utility model relates to long-distance slurry pipelined storage device, relates to more specifically a kind of slurry memory storage with overflow precise monitoring function.

Background technology

At China's fast increasing economy, particularly metallurgical in recent years, petrochemical industry, oil, the sustainable and stable development of the industries such as chemical fertilizer, price lifting along with the energy, traffic cost is more and more higher, and utilize hydraulic pipe conveying solid substance material, transport (as railway with other, highway) compare, there is transportation range short, capital expenditure is few, landform is adapted to and can utilize discrepancy in elevation potential energy, do not account for or account for less soil, free from environmental pollution and not disturbed by external condition, can realize continuous working, technology is reliable, working expenses is only railway, the plurality of advantages such as 1/6～1/10 of highway, realized economy, environment sustainable development.Slurry agitating tank is widely used in Slurry Pipeline Transportation systems at different levels as conventional slurry memory storage, as the Dahongshan slurry delivery pipe line being constructed and put into operation for 2006, when the pipeline of long 171 kilometers is transported to each dehydrating plant of Kunming Iron and Steel Works, at initial pumping plant, need to have 4 of 2 of 12 meters of slurry agitating tanks and 16 meters of slurry agitating tanks, two intermediate pump stations respectively have each 1 of 12 meters and 16 meters of slurry agitating tank on the way.This slurry agitating tank as slurry memory storage need to be offered outgate at top, slurry in flowing into tank diameter will overflow to factory trench by outgate while exceeding scheduled volume, and when certain tank diameter generation slurry overflow, need to cut off in time the slurry supply to it, therefore accurately know whether each slurry agitating tank slurry overflow occurs significant for controlling of whole slurry delivery system.Based in this prior art as shown in Figure 1 in slurry holding tank 1, be provided with liquidometer 3, and export the liquid level numerical value of liquidometer 3 to indicative control unit 4, thereby the level readings that reads liquidometer 3 by indicative control unit 4 judges whether slurry holding tank 1 overflow has occurred, because overflow pipe 2 is connected in the predetermined fluid level At The Height at slurry holding tank 1 top, when the liquid level value detecting when liquidometer 3 reaches the liquid level at overflow pipe place, can think that overflow phenomena has occurred slurry.This slurry overflow monitoring scheme of the prior art has larger limitation in actual use, make it cannot monitor accurately in real time the overflow of slurry holding tank, such as fluctuating when liquidometer self, or while there is larger fluctuation in the slurry liquid level in inflow slurry holding tank, as shown in Figure 1, slurry liquid level in liquidometer place may be lower than the slurry liquid level of overflow pipe junction, according to the monitoring of liquidometer, now can there is not overflow like this, but in fact at overflow pipe place, there is overflow phenomena, if while now continuing slurry holding tank supply slurry according to the monitoring result of liquidometer, possibility is accidents caused because of the serious overflow of slurry, therefore existing slurry overflow monitoring scheme exists larger defect, this defect is carried and can be produced larger potential safety hazard long-distance slurry pipeline, a kind of slurry memory storage that can precise monitoring slurry flooded conditions need to be provided.

The specific embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail, so that those skilled in the art can more clearly understand the utility model, but does not therefore limit protection domain of the present utility model.

As shown in Figure 2, slurry memory storage described in the utility model comprises slurry holding tank 1, overflow pipe 2, liquidometer 3, indicative control unit 4, approach switch 5 and annunciator 6, described slurry holding tank 1 is slurry agitating tank preferably, at the top of slurry holding tank, sidewall has outgate, described overflow pipe 2 is connected in described outgate, concrete described outgate is opened in the tip position apart from slurry holding tank top end opening 0.2-0.5 rice, the mouth of overflow pipe 2 is connected to factory trench, by overflow pipe, realizing the overflow of excessive slurry in injection slurry holding tank exports, guarantee slurry supply security.On described overflow pipe 2, be provided with approach switch 5, described approach switch is a kind of slurry sensed position switch, when having slurry to flow into overflow pipe 2, described approach switch just can produce induced signal, thereby can in point-device perception overflow pipe, whether there is slurry to overflow, preferred described approach switch 5 is arranged at the bottom surface of overflow pipe, thereby accurately perception slurry overflow, and described approach switch 5 is connected in annunciator 6, thereby when having slurry to flow into overflow pipe 2, described approach switch 5 is connected and to described annunciator 6 output switch energizing signal, send overflow alerting signal by the annunciator very first time, remind staff to notice that in slurry holding tank, overflow has occurred slurry the very first time, guaranteed to greatest extent the confession slurry safety of slurry holding tank.

In order further to improve overflow monitoring accuracy rate, the utility model is preferably provided with liquidometer 3 in slurry holding tank, described liquidometer 3 flows into the slurry liquid level in slurry holding tank for Real-Time Monitoring, and the signal output part of described liquidometer 3 is connected in indicative control unit 4, thereby the holding tank entoplasm body fluid position information of its monitoring is shown to output in real time, for operating personal, take appropriate measures, the signal output part of further described annunciator 4 is also connected in indicative control unit 4, for while output alarm information.In described indicative control unit, prestore the liquid level information of overflow pipe junction.Why in scheme of the present utility model, comprise simultaneously approach switch 5 and liquidometer 3 be because: during the low level of the slurry in slurry holding tank in non-overflow, slurry in slurry holding tank likely can be splashed in overflow pipe 2 and be monitored by its approach switch in slip casting process, at this moment there is not overflow in slurry reality, so but approach switch 2 is because monitoring the work of signal meeting trigger alarm device, needs judge in conjunction with the level value of liquidometer monitoring when this thing happens simultaneously.After annunciator is reported to the police, need to observe the level value that liquidometer monitors by indicative control unit simultaneously, when level value that now liquidometer monitors is starkly lower than the level value of overflow pipe junction, judge that overflow does not occur slurry holding tank reality.By this, preferably comprise that the scheme of liquidometer and approach switch can further improve overflow sensing precision simultaneously.

Slurry memory storage provided by the utility model can monitor accurately slurry whether overflow occurs, overcome prior art and depended merely on the defect that liquidometer reading cannot precise monitoring slurry overflow, for the slurry supply in slurry holding tank provides accurate control reference information, guaranteed slurry supply security.

Below be only that preferred implementation of the present utility model is described; the technical solution of the utility model is not limited to this; the any known distortion that those skilled in the art do on the basis of major technique of the present utility model design all belongs to the claimed technology category of the utility model, and the concrete protection domain of the utility model is as the criterion with the record of claims.
