Description
Technical field
The utility model relates to a kind of concrete production field more particularly to a kind of Outputting Pre-cooling Concrete production equipments.
Background technique
Outputting Pre-cooling Concrete production, refers to before concrete mixes and stirs, by raw material (stone, sand, water, cementitious material, additive
Deng) the cooling reduction of temperature.
Such a case is frequently present of in engineering: after with a certain or two kinds of pre-cooling measures, from going out for design
Only poor 1~2 DEG C of machine mouth temperature, it is necessary to add a pre-cooling technical measures again.Such as: taking batching plant feed bin First air
Cold plus flake ice and cold water are mixed as pre-cooling measure, outlet temperature only relatively 1~2 DEG C of value difference of design, that is to say, that each single item
The cooling extent of pre- refrigeration technique has its limit, it usually needs and multinomial equipment complex, which utilizes one's abilities, meets production requirement, and in reality
In the production of border, installation, operation and equipment cost will be just significantly increased by increasing a set of equipment, and more equipment also bring it is bigger
Security risk and risk of leakage, especially in remote construction of hydropower plant, since landform is precipitous, it is whole to increase by one for narrow space
Cover Pre-cooling equipment, it tends to be difficult to realize.

Degree is the lowest limit temperature of gravelstone air cooling system evaporating temperature, it is clear that the lowest limit temperature cannot achieve middle building stones storehouse, big
Building stones storehouse and especially big feed bin all have optimal wind chill temperatures, that is, reduce middle building stones storehouse, big building stones storehouse and especially big building stones storehouse
Cooling efficiency, that is, reduce the pre- cold efficiency of air cooling system.
