Problems solved by technology

Large-volume concrete projects are often located in alpine and canyon areas with complex terrain. The site leveling and excavation required to build a primary air-cooled silo is extremely large, which further increases the direct cost of primary air-cooling
The production of flake ice needs to set up an ice-making building, which has complex processes, many equipments, and a large amount of gold knots for steel structures

Abstract

The invention relates to a precooling device, in particular to a concrete aggregate precooling device. The concrete aggregate precooling device is simple in structure, capable of quickly cooling aggregate and small in water consumption. The concrete aggregate precooling device comprises a base, wherein supporting plates are symmetrically arranged at the top of the base; a conveying unit, wherein the conveying unit is arranged between the supporting plates; and a precooling unit, wherein the precooling unit is arranged on the supporting plates. Rotation of the conveying belt is achieved by rotating a handle, then through cooperation of the conveying unit and the precooling unit, water is scattered by the precooling unit when aggregate moves rightwards, the aggregate is rapidly cooled, intermittent water scattering of a sprinkler is achieved through left-right movement of a guide pipe, and then water is saved. A servo motor is started to drive a cylindrical notch block to rotate, and then intermittent discharging of aggregate and automatic conveying of the conveying unit are achieved.

Description

technical field [0001] The invention relates to a precooling device, in particular to a concrete aggregate precooling device. Background technique [0002] Aggregate, also known as aggregate, is a granular material that acts as a skeleton and filling in concrete and mortar. Commonly used aggregates are crushed stone and pebble. Due to the short time available for pouring concrete under natural conditions, it is restricted normal construction time. [0003] In order to meet the normal construction of concrete under the high temperature construction conditions in summer, technological measures must be taken to pre-cool the concrete. At present, aggregate air cooling, adding flake ice and cold water mixing are common pre-cooling technologies for the production of pre-cooled concrete. In large hydropower stations It has been widely used in the construction of large-volume concrete projects such as engineering. Aggregate air cooling can be subdivided into ground air cooling and...
