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 for concrete aggregates. The present invention provides a concrete aggregate pre-cooling device capable of moving aggregates, increasing the gap between aggregates, and improving pre-cooling efficiency. A concrete aggregate pre-cooling device, comprising: a base, on which both sides are connected with mounting frames; a feed pipe, a side of the base close to one side of the mounting frame is connected with a feed pipe; a rotating mechanism, the mounting frame is connected to the feeder A rotating mechanism is installed between the material pipelines; a pressurizing mechanism is installed on the base, and the pressurizing mechanism is connected with the rotating mechanism by transmission. The present invention can make the aggregate rotate and move to the right through the rotating mechanism, so as to achieve the purpose of enabling the aggregate to move and to increase the gap between the aggregates. By spraying on the aggregate, 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 pre-cooling device for concrete aggregates. Background technique [0002] Pre-cooled aggregate refers to a technological measure that pre-cools the concrete aggregate before entering the mixer to reduce the calorific value of the concrete mixture. [0003] After searching, the patent publication number is: CN107310012A, which discloses a concrete aggregate pre-cooling device, including a base, a support, a cooling box, an ice-cooling device, a cooling device, etc. There is an ice-cooling device, a cooling box on the right side of the ice-cooling device, a first feeding hopper in the middle of the top of the cooling box, a first opening on the left wall of the cooling box, a blowing device on the upper part of the right wall of the cooling box, and a bottom of the cooling box. A discharge hopper is provided, and a valve is provided on the discharge hopper. The present invention achieves the...
