Description

Vibration sand-washing device

Technical field

This utility model relates to casting washed-out sand technical field, is specifically related to a kind of vibration sand-washing device。

Background technology

In China, core, sand mold that casting industry needs in producing every year at least want several ten million tons。Wherein, silica sand because it is cheap, rich reserves and be widely used in casting process。

Research both at home and abroad at present specify that Foundry Production is had important impact by the following performance indications of silica sand: clay content, acid consumption value, refractoriness, burning decrement, pH value etc.。Wherein the size of clay content directly affect use casting silica sand make core, sand mold intensity。Industry standard defines: the direct < 0.02mm granule part mass mark contained in clay content-roughing sand。And clear stipulaties in a standard: clean sand clay content < 0.3%, washed-out sand clay content < 0.5%。So the less product of clay content commercially will necessarily rely on the performance of its high-quality to occupy the bigger market share, also can reduce the consumption of Foundry Works's binding agent simultaneously, in terms of cost angle or utilization of resources angle, all have very big benefit。

And at present prior art proposes and utilizes ultrasound wave that silica sand is carried out, its critical piece has and cleans tank body, water inlet pipe, ultrasound wave shake plate and collect the overfall of sewage；Operation principle is first to be poured into by silica sand in purge tank body, ultrasound wave shake plate work, the mud part making silica sand is separated with pollutant, added water from cleaning tank base by water inlet pipe simultaneously, pollutant and silica sand are separated under the effect of water, pollutant are floated and are discharged by the overfall on cleaning tank body top, and silica sand is then discharged from the outlet cleaning tank base, it is achieved ultrasound wave washed-out sand；Although this technology is compared traditional scouring method and is improve certain efficiency, but although the high frequency sound wave washed-out sand effect of generation is notable during ultrasound wave shake plate work, but the health of operator can be produced bigger injury by the penetration power that simultaneously ultrasound wave is higher, the noise of generation and cavitation, is in the health that can have a strong impact on human body in high frequency sound wave environment for a long time。And ultrasound wave shake plate cost is higher, it is easy to damage and be not easily repaired, the shake plate that often can only more renew after damage, maintenance, use cost are higher so that casting washed-out sand is relatively costly, in actual production and inapplicable。
