Sand aggregate temperature control system

Abstract

The invention provides a sand aggregate temperature control system. The sand aggregate temperature control system comprises a pre-cooling part, an aggregate conveying part, a refrigerating part and aliquid conveying part; a heat exchange structure is arranged in the pre-cooling part; the aggregate conveying part is used for conveying aggregate into the pre-cooling part; the refrigerating part isused for refrigerating or heating pre-cooling liquid; the refrigerating part is connected with the pre-cooling part through the liquid conveying part; the liquid conveying part conveys the pre-coolingliquid into the pre-cooling part, so that the pre-cooling liquid makes contact with the heat exchange structure and exchanges heat with the heat exchange structure; and the pre-cooling part discharges the pre-cooling liquid, and the aggregate conveying part conveys the aggregate to the pre-cooling part, so that the aggregate makes contact with the heat exchange structure and exchanges heat with the heat exchange structure. The problems of large occupied area and low production efficiency of existing water-cooled aggregate pre-cooling are solved. According to the sand aggregate temperature control system, through mutual cooperation of the pre-cooling part and the heat exchange structure, the site size required by aggregate pre-cooling is reduced, use of narrow sections such as river valleys is facilitated, and the use range is expanded; and a large amount of pre-cooling can be carried out at the same time, the pre-cooling time of single-batch aggregate is shortened, and the pre-coolingefficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of temperature control systems, and in particular relates to a sand aggregate temperature control system. Background technique [0002] Aggregate, also known as "aggregate", is a granular material that acts as a skeleton and filling in concrete and mortar. Natural sand is generally used, such as river sand, sea sand and valley sand, etc. When there is a lack of natural sand, artificial sand ground from hard rocks can also be used. [0003] Before aggregate is used, taking aggregate for concrete as an example, proper heating or cooling should be carried out according to the actual construction environment to reduce the temperature difference between aggregate and other raw materials in concrete, which will help improve the quality of concrete. [0004] The existing aggregate pre-cooling methods are commonly used in the following ways: air-cooled, the aggregate is stored in the stockpile of a large cold stora...
