Summary of the invention
Technical problem to be solved in the utility model provides a kind of reasonable in design, energy consumption is low, feed bin is little, blast is low, equipment is few, control is simple, the loss of leaking out is low, cooling extent greatly, the air-cooled aggregate air cooler of the air-cooled replacement secondary of available one-level under certain condition.
It is this aggregate air cooler that the utility model solves the problems of the technologies described above the technical scheme that is adopted, form by feed bin, air outlet, air inlet and airduct, feed bin is divided into aggregate bin and Sha Cang, its design feature is: air outlet and air inlet are arranged on the aggregate bin, described airduct is blast pipe, backwind tube, air intake communicating pipe and return air communicating pipe, wherein, blast pipe and backwind tube are transversely arranged, air intake communicating pipe and return air communicating pipe are vertically to arrange, backwind tube is arranged between the adjacent blast pipe, and blast pipe was connected with air intake communicating pipe.
Airduct described in the utility model is more than a cover or overlaps.
Air intake communicating pipe described in the utility model is arranged in sand storehouse or the feed bin.
The lower open of blast pipe described in the utility model and backwind tube, both sides are the shutter form.
The utility model is compared with prior art and is had the following advantages and effect: 1, owing to multilayer turnover wind in the utility model branch storehouse, be equivalent to the wind area and increased many times, under the situation identical of feed bin cross section, can provide many times cold with saturating material wind speed and other parameters.2, owing to used the shutter airduct, make that in feed bin cold wind can be penetrated in the aggregate equably, and aggregate is fully cooled off.3, because aggregate at different levels continuous feed has simultaneously been kept each storehouse and bought securities with all one's capital, guarantee the stable of material level, thereby kept the stable of cooling operating mode, guaranteed that cooling load is steady, cut down peak load and reduced the concrete temperature fluctuation.4, the loss of leaking out is air-cooled main loss, adopts the utility model, can increase air quantity and to keep blast constant, and the loss of leaking out relatively reduces by 2/3.4, the utility model is under the windage same case, and total stock column height is the several times of tradition cooling, increases ratio of height to diameter and satisfies dark storehouse condition, can keep the aggregate first in first out, guarantees that the aggregate that successively enters all has sufficient cool time in aggregate bin.5, owing to be arranged on air intake communicating pipe in the adjacent sand storehouse, can cool off the material in the sand storehouse.
