Background technology
At present, the transfer pipeline of liquid is the cleaning of discharge pipe line particularly, especially major diameter, length seldom adopt the method for chemical cleaning solution and water under high pressure to clean apart from the mediation that the drainage pipeline inwall adheres to dirty thing, comparatively Chang Yong method is that washer or machinery clean, as by the circular acanthosphere washer of waterpower or fluid pressure walking, waterpower vane type washer etc.This dependence hydro-cleaning installation dirty thing of mobile removing in pipe has simple and convenient, and the advantage of saving cost is present general apparatus for eliminating sludge and method.
In order not influence the needs of normal draining, general scale removal cleaning is just carried out when to be that the fouling in pipeline is thicker have a strong impact on displacement, and this is to stop draining, and the non-return valve of lower end of duct setting is removed, change the preceding paragraph short pipeline, to eliminate non-return valve valve plate stopping to wiper.On pipeline, connect then the emission storehouse is installed, pipeline is cleaned with wiper.Common dirt layer is the impurity deposit in the water, and the pigging difficulty is less, and the general several days time is capable of washing finishing, but this is for the heavier underground activities places such as mine of draining task, has bigger danger and difficulty.The thickness and the hardness of dirt layer are big more, and the time that cleaning and descaling needs is long more, and workload is big more.
In addition, when the hardness of water of discharge of pipes is big, be that the content of calcium in the water, magnesium salts is when higher, inwall at pipeline at first can form loose calcareous fouling thin layer, at this moment adopt common water driven mechanical tube cleaner just can remove, along with the prolongation of time, the layer of scale of inner-walls of duct is more and more thicker, the dirt layer chemical change takes place gradually and then forms with calcium carbonate and magnesium salts is the hard layer of scale of main component, at this moment uses water driven mechanical tube cleaner can't remove fouling.
Find no by retrieval and close discharge pipe line carries out scale control treatments and cleaning after installation relevant report.
Summary of the invention
The scale control treatments and the cleaning method that the purpose of this invention is to provide a kind of discharge pipe line, the mistaken ideas of having eliminated existing cleaning and descaling technology have guaranteed the operate as normal of discharge pipe line.
The technical solution used in the present invention is:
The scale control treatments of drainage pipeline and cleaning method, be used for the scale control treatments and the cleaning of mine, industrial drainage pipeline, it is characterized in that comprising water inlet, the draining pump of water inlet, wiper emission storehouse, non-resistance non-return valve and the drainage pipeline that pipeline connects successively at drainage system, when pipeline is installed back examination draining, at first the foreign matter that may exist in the pipeline is got rid of cleaning with wiper, the regular then physical scale in the pipeline is cleaned, and prevents the formation of chemistry dirt layer.
Described non-resistance non-return valve by with the joining valve shell of pipeline, valve plate and valve shell on the valve seat that is provided with form, the valve plate of unidirectional unlatching is hinged on the valve seat, the lower surface of valve plate and valve seat matched when valve plate was closed, the maximum open degree of valve plate is 90 °, the upper surface of valve plate is provided with the spring perpendicular to the valve plate face, and spring guarantees that valve plate is opened the limit angle when normal draining be 70 °.
When preventing that wiper from passing through non-return valve, scale removal cutter nail and valve plate lower surface rub and cause the damage of the two, and an elastomeric material protective layer is set on the valve plate lower surface of this non-resistance non-return valve, and this elastomeric material can be macromolecular materials such as nylon, rubber.
When the pH value of pipeline water 〉=7.5, add the seal cover of freely opening at the delivery port place of drainage pipeline.
Be provided with seal washer in the seal cover that the upper end at seal cover and drainpipe road junction is hinged and pipeline opening cooperates.
Might there be construction foreign material such as wood, iron, stone class in pipeline after just having installed, when the examination draining, carry out prerinse and not only can remove foreign material in the various pipelines with wiper, can also be well understood to the situation of inner-walls of duct, discovery in time can hinder the obstacle of wiper, eliminates pipeline obstruction accident potential.The hardness of pipe scale layer and thickness are to increase along with the prolongation of water discharge time, and the physics and the chemical property of dirt layer also can change, and clean difficulty and strengthen thereupon.Among the present invention wiper being launched storehouse and non-resistance non-return valve is installed in the drainage pipeline as the indispensable facility of drainage pipeline, can clean discharge pipe line at any time, when the pipe scale layer approaches and only form loose physics dirt layer, pipeline is cleaned, can not only save time, the cleaning difficulty is little, can also remain the unimpeded of pipeline, reduce draining and clean cost.
Every interval certain hour or when observing inner-walls of duct new layer of scale being arranged, wiper can be sent into the pipeline from wiper emission storehouse, wiper advances and tube wall incrustation is cleaned at the promotion lower edge of current pipeline, when wiper passes through the non-resistance non-return valve, valve plate is issued to maximum opening angle in the promotion of wiper, after wiper passes through, it is 70 ° that valve plate upper surface spring makes valve plate reset to opening angle, to be implemented under the situation that stops draining, valve plate can be closed under the effect of recirculation water.
The calcareous hard dirt layer of carbonic acid is because the surface that soluble calcium salt in the high hardness water and magnesium salts are deposited on pipeline, and when tube emptying, calcium salt contact with air with magnesium salts, the formation of generation chemical reaction.When pipe scale is loosened in formation just, clean or avoid air to enter pipeline as far as possible or make all the time being full of water in the pipeline, can prevent the formation of hard dirt layer to greatest extent.The seal cover at the delivery port place of drainage pipeline and the upper end at drainpipe road junction are hinged, and seal cover seals delivery port during not draining of pipeline, and current are pushed seal cover open during draining.When drainage works stopped suddenly, seal cover sealed effluent pipe mouth under the action of pressure that aqueous reflux forms, thereby avoids air to enter in the pipeline.
Beneficial effect of the present invention is, by drainage pipeline is carried out scale control treatments and cleaning, can carry out scale removal to pipeline at any time and clean; eliminated of the influence of dirty layer to drainage works; remain the unimpeded of pipeline, reduce draining and clean cost, the shutdown of having avoided influencing drainage works is cleaned.The present invention can be widely used in the scale control treatments and the cleaning of the discharge pipe line after new installation pipeline and the process cleaning.
