Problems solved by technology

The present invention achieves the effect of a concrete aggregate pre-cooling device that can cool concrete aggregates in multiple ways to maximize efficiency, and can recycle water for use. Although this patent can pre-cool aggregates, this patent The patent makes all the aggregates piled up in the cooling box, so that the aggregates are in a static state, resulting in a small gap between the aggregates, resulting in slower heat dissipation, and lower pre-cooling efficiency

Abstract

The invention relates to a cooling device, in particular to a pre-cooling device of concrete aggregate. The pre-cooling device of the concrete aggregate enables aggregate to move, can increase gaps among the aggregate and improve the pre-cooling efficiency. The pre-cooling device of the concrete aggregate comprises a base, a feeding pipeline, a rotating mechanism and a pressurizing mechanism, wherein the two sides of the upper side of the base are both connected with mounting frames, the side, close to the mounting frame on one side, of the base is connected with the feeding pipeline, the rotating mechanism is mounted between the mounting frame and the feeding pipeline, the pressurizing mechanism is mounted on the base, and the pressurizing mechanism is in transmission connection with the rotating mechanism. The aggregate can be rotated and moved rightwards through the rotating mechanism, so that the purposes of moving the aggregate and increasing the gaps among the aggregate are achieved; cold water can be sprayed onto the aggregate through cooperation of the pressurizing mechanism and a water spraying structure, then the aggregate can be pre-cooled, and the pre-cooling efficiency can be improved.

Description

technical field [0001] The invention relates to a cooling device, in particular to a concrete aggregate pre-cooling device. Background technique [0002] Pre-cooling aggregate refers to the process of cooling the concrete aggregate before entering the mixer to reduce the calorific value of the concrete mixture.
