Abstract
The utility model provides slurry exhaust apparatus before a kind of delivery pump.Including pump pond, the blast pipe higher than pump pond is installed on pump pond outlet, conveying pumping intake piping, valve is installed in blast pipe root, threeway is installed above the valve, valve is installed in threeway.The utility model has advantages below：（1）Blast pipe makes bag be dissolved in the gas in ore pulp to drain, reduce the cavitation of delivery pump.（2）Exhaust apparatus alleviates gradual fatigue damage and caused metal surface of the slurry to the surface of the flow passage parts such as the impeller, backplate, spiral case of delivery pump and degraded, and then reduces and the cellular scoring of size occur, extends spare part service life, reduces spare parts consumption.（3）When slurry blocks blast pipe, blast pipe is periodically dredged by threeway using water under high pressure.
Description
Technical field
Technique waste water process field is the utility model is related to, particularly a kind of delivery pump front row device of air.
Background technology
In nonferrous metallurgical process, certain acid waste water will be produced, it is full to enable industrial acidic wastewater qualified discharge
Toe ring is protected, closes and advise legal production requirement, and mine tailing of the ore after ore dressing is stored up, be converted into by being delivered directly to originally in Tailings Dam
With industrial acidic wastewater after processing is up to standard, Tailings Dam stockpiling is delivered to by delivery pump.Whole processing procedure utilizes acid waste water
With the alkaline components Multi-stage stirring mixing in slurry, neutralization, vulcanization, water purification agent coagulating kinetics.Slurry gives up with commercial acid
During water neutralization reaction, chemical reaction occurs and produces substantial amounts of sour gas, in addition to a part is actually taken up by gas tower processing, its residual air
Body is dissolved in ore pulp by bag in the form of bubbles, when the bubble being dissolved in by bag in ore pulp enters the higher region of pressure in pump, is pressurized
Rupture suddenly, then the slurry of surrounding just hitherward supplements, and forms continuous local assault load, makes impeller, the shield of delivery pump
The gradual fatigue damage in surface of the flow passage parts such as plate, spiral case, causes degrading for metal surface, and then the cellular scoring of size occurs,
Accelerate spare part loss.And because the unstability of impact load causes delivery pump, pipeline that vibration and noise occurs, it is driven valve
Mechanism is damaged, and spare part is changed in often maintenance, increases labor intensity, simultaneously because steam bubble clogging impeller conduit, makes its flow, lift
Reduce, efficiency declines.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of slurry delivery pump front row device of air.
Technical scheme is used by the utility model solves its technical problem：
A kind of delivery pump front row device of air, including pump pond, it is characterised in that the conveying pumping intake piping（1）On be provided with
Higher than the blast pipe in the pump pond（2）；In the blast pipe（2）The upper and conveying pumping intake piping（1）The position installation to cross
There is valve（3）；In the blast pipe（2）On valve（3）Top is installed by threeway（4）, the threeway（4）On valve is installed
（5）.
The utility model has advantages below：（1）Blast pipe makes bag be dissolved in the gas in ore pulp to drain, reduce the cavitation erosion of pump
Phenomenon.（2）Exhaust apparatus alleviates slurry and the gradual fatigue on the surface of the flow passage parts such as the impeller, backplate, spiral case of delivery pump is damaged
Bad and caused metal surface is degraded, and then reduces and the cellular scoring of size occur, extends spare part service life, is reduced spare part and is disappeared
Consumption.（3）When slurry blocks blast pipe, blast pipe is periodically dredged by threeway using water under high pressure.
Brief description of the drawings
Fig. 1 is delivery pump front row of the present utility model device of air.
Embodiment
As illustrated, a kind of delivery pump front row device of air, main body includes conveying pumping intake piping 1, conveys and pacify on pumping intake piping 1
Blast pipe 2 equipped with higher than pump pond, the position to be crossed on blast pipe 2, with conveying pumping intake piping 1 are provided with valve 3（Arranging
The root of tracheae 2 is installed by valve 3）, the top of valve 3（Against the position of valve 3）Threeway 4 is installed, valve 5 is installed in threeway 4.
As shown in figure 1, the root valve 3 of blast pipe 2 is opened at conveying pumping intake piping 1, the valve 5 installed in threeway closes
Close, when ore pulp flows through inlet tube 1 from pump pond, Bao Rong saturated gas excludes from blast pipe 2 in ore pulp.When operation a period of time
Afterwards, open installation valve 5 in threeway and see if there is slurry and flow out and judge whether the root of blast pipe 2 blocks, such as block and utilize inspection
When repairing time stopping slurry conveying, access water under high pressure is dredged at valve 5.Meanwhile if more than threeway exhaust pipe plug
Plug, valve 3 can be closed, open access water under high pressure at valve 5 and dredged, so that delivery pump is in the case of efficient, low consumption
Slurry up to standard after processing is delivered in Tailings Dam and stored up.
Claims (1)
