Description
Technical field
The utility model is related to pumping unit field, more particularly to a kind of foam pump and foam delivery system.
Background technology
The foam of ore deposit flotation operation is often conveyed with centrifugal pump in ore-dressing practice.Common Pulp pump can not generally be met
Technological requirement.Most common phenomenon be pump flow, lift and efficiency far below design load or conveying clear water when operating mode.It is former
Because being：A large amount of steam bubbles that medium contains, enter suction eye before can due to the pressure subatmospheric in medium without
Disconnected expansion, closer to suction eye, steam bubble expands bigger, pump is just generated when flow is far below design discharge serious
Cavitation phenomenons, so as to cause the flow of pump, lift and efficiency substantially less than design load, simultaneously because the generation of cavitation phenomenons, general
The antifriction alloy flow passage part of logical Pulp pump shows that cellular cavitation hole can be produced, and causes flow passage part initial failure, in this work
Under condition, it is necessary to use foam pump.
In conveying vapor content (referring to the volume ratio of air in media as well) low foam, such as when foam vapor content 30% with
When lower, existing foam pump can typically meet technological requirement, but when vapor content is up to more than 40% in foam, existing foam pump
Conveying effect is very poor.This is due to that in addition to cavitation, another factor may also cause pump when conveying ore dressing foam class medium
Flow, lift be remarkably decreased, here it is the circulation phenomenon in impeller, i.e. medium are oppositely oriented with impeller between two blades
Annular flow.This annular flow not only causes the efficiency of pump to decline, while also declining the flow of pump.Due to ore dressing foam
It is a kind of solid, liquid, vapour three-phase flow, the difference in specific gravity of vapour phase proportion therein and solid phase and liquid phase is very big, circulation effect causes to be situated between
Matter produces classification between the blades, and solid particle and liquid are larger due to proportion, and the outer of ring is thrown under the influence of centrifugal force
Side, and gas forms air mass then due to the smaller middle part that ring is wrapped in by liquid and solid particle of proportion.If the gassiness of medium
Relatively low, the small volume of air mass is measured, easily

Beneficial effect：
In open type or half-opened impeller, between the air bolus produced due to circulation can be between blade and preceding liner
Gap enters between another group of blade, so as to advantageously reduce the intensity of circulation between blade；The volume of air bolus in impeller is reduced,
Prevent from or reduce pump to stop when conveying the medium of high air content, so as to improve the flow of pump.
Blade is that primary blades are tilted close to one end of suction inlet to the direction away from impeller central point in entrance point distortion, is had
Beneficial to the exclusion phenomenon that blade is produced in entrance point is reduced, the anti-cavitation performance of pump is improved, pump is reduced and the possibility stopped occurs.
Blade can make blade to medium work done in advance to suction inlet extension, be conducive to improving the anti-cavitation performance of pump, subtract
There is the possibility stopped in few pump.
General slurry Pump Suction Nozzle sectional area is 1.5-2.5 times or so of discharge opening sectional area, can so be obtained higher
Clear water efficiency.The sectional area of suction chamber is set to 3-10 times of discharge opening sectional area by the utility model, can cause the clear of pump
Water efficiency has declined, but is conducive to foam class medium to enter in impeller, can prevent medium before impeller is entered because pressure is bright
Show reduction and cause the bubble significantly expansion in medium and serious cavitation occur.
The blade quantity of this programme is limited to 3-7 pieces, and its structure for conveying is more simple, its leaf position, the setting of shape
Be conducive to improving anti-cavitation ability.
Composite abrasion resistance material has preferable anti-cavitation performance, and preceding liner, rear liner and impeller use complex abrasion-proof material system
Make, the life-span of pump flow passage part can be significantly improved, research shows, not only wearability is significantly stronger than resistance to break-in to composite abrasion resistance material
Gold, the advantage of its cavitation-resistance is more prominent, and its reason is that nonmetallic materials are insensitive to cavitation damage.
In the operating mode that some are gently denuded, preceding liner, rear liner are manufactured using rubber, preferable cavitation-resistance can be obtained
Can, while manufacturing cost also has some superiority.The impeller that is manufactured using antifriction alloy, preceding liner, rear liner cost are relatively low, one
A little light abrasion operating modes can also obtain application.
Procapsid, back casing and the impeller framework of metal material are set, it is ensured that the intensity of the pump housing and impeller.
Foam delivery system sets froth breaking groove and the pipeline connected with foam pump discharge opening, and the part that foam pump is exported is situated between
Matter is by the return froth breaking groove of pipeline, and the medium that this part is returned is due to the drastically change by pressure in pump, from pump discharge opening row
After going out after pipeline, most of air and solid phase, liquid phase medium are separated comes, after nozzle ejection, only seldom
Number re-forms foam, and most of air is discharged into air, and this partial solid phase and liquid phase medium are reentered after froth breaking groove, and one
Aspect can improve the solid phase of medium and the ratio of liquid phase, can smash to float over and disappear when on the other hand being sprayed into by high speed in froth breaking groove
Groove air content at the middle and upper levels very high foam is steeped, the common results of two kinds of effects can significantly reduce medium in froth breaking groove
Air content, so that improve the mobility of medium, the influence of reduction cavitation and circulation effect to pump, and significantly improve the defeated of system
The amount of sending.
General ore dressing foam is more sensitive to stirring action, and foam easily ruptures under stirring, air after lather collapse
It is discharged into air, froth breaking groove and agitating device is set, it is possible to use agitating device destroys foam, and makes medium in froth breaking groove
Overall accumulated amount is remarkably decreased, while the air content in medium is also remarkably decreased, so that the mobility of medium is improved,
The influence of cavitation and circulation effect to pump is reduced, and the conveying capacity of pump is also significantly improved.
