Chinese patent literature CN 1878615 discloses a kind of method of building waste sorting.In described method, the building castoff that is ground into preliminary dimension is joined in the liquid of stillpot, and in groove, be isolated into various components according to proportion, wherein, described liquid has than low but higher than the proportion of the remaining ingredient reference specific gravity of proportion that reclaims component, thereby the component that will reclaim is separated by the bottom that is deposited to described stillpot.According to described method, by simple step, just can easily other impurity that is included in the building castoff be separated with the aggregate that reuses of high-quality.Particularly, the reference specific gravity of separating liquid is carried out suitable adjustment, thus even can be easily with the various materials heavier than water, such as separation such as tile, common brick, bituminous concrete, cement lumps aggregates., this separation method, it need to utilize chemical substance, such as tetrabromoethane, ethanol, be deployed into different specific weight, the material that can not separate by allocating different proportion, this method with the organic chemicals building waste sorting, its processing to last remaining chemical liquid also is difficult, and directly discharging certainly will be to environment, and, the utilized material that deals in this way, its price is quite expensive, and the angle from cost loses more than gain.

Summary of the invention

The objective of the invention is for the problems referred to above, provide a kind of utilization that environment is not had contaminant water as medium to society, and can reach the vertical streaming recirculated water solid building castoff seperator of isolating different material in the building castoff.

Technical scheme of the present invention is: design a kind of vertical streaming recirculated water solid building castoff seperator, comprise high water level pond, low water level pond and delivery port, described delivery port is located on the low water level pond, is provided with the solid building castoff section that feeds intake above described delivery port; Under the effect of high water level Chi Shui, water sprays from delivery port, will be divided into two parts from the separated material that the solid building castoff feeds intake under the clan, directly enters the low water level pond than heavy material, and the material of light specific gravity enters first with current and accommodates the pond; The first water of accommodating the pond is drawn back the high water level pond through water circulating pump and is recycled.

As improvement of the present invention, described high water level pond be connected the low water level pond and connect by valve.

As improvement of the present invention, described water is decided according to the proportion of separated material from the speed that delivery port flows out.

" building castoff " of indication has the same meaning with " separated object " among the present invention, and it refers to a kind of concrete, brick, stone or watt rear resulting mixture of quilt pulverizing that removes from building for building that contain.

As mentioned above, the present invention compared with prior art has following advantage, separating medium of the present invention is water, be different from the suspension that adopts chemical substance to do, it not only can be recycling, even and waste water can not cause any pollution to environment yet; Again, water can obtain different separators with relatively low cost as medium from building castoff, such as stone, brickbat, broken concrete etc., classify, and these materials all can reuse.The present invention can not only can realize the building gurry is separated, and can also realize floating thing, and such as paper, styrenic foams, wood chip be or/and the synchronously removal of impurities such as polybag, can save selection by winnowing in the conventional process building castoff except step, achieves many things at one stroke.
