Abstract

The invention discloses a rapidly heating or cooling device for solid granules. The rapidly heating or cooling device comprises a liquid circulating system, a gas circulating system and a stirring device, wherein by using the liquid circulating system and the gas circulating system, a liquid medium and a gas medium are simultaneously used for heating / cooling the solid granules through a double-layer hollow stirring tank shell so that the heating / cooling efficiency is effectively increased, wherein the heated / cooled gas is uniformly mixed together with the solid granules through arranging a gas conveying passage in a stirring device blade so that uniform heating / cooling is realized; the liquid circulating system and the gas circulating system share one set of heating / cooling equipment so that resources can be effectively saved; in order to increase the liquid medium circulating efficiency and satisfy temperature increasing / speed reducing requirements, the liquid medium circulating passage is designed to fully cover the whole shell and diverting and converging passages are additionally formed so that the whole hell is uniformly heated / cooled; meanwhile, the rapidly heating or cooling device for the solid granules, disclosed by the invention, can be also used as stirring equipment for rapidly heating and cooling other solid granules.

Description

technical field [0001] The invention relates to a temperature control device for road construction, in particular to a rapid heating or cooling device for solid granular materials. Background technique [0002] With the rapid development of highway engineering construction and the continuous increase of highway mileage, road engineering construction and maintenance consume a lot of resources, environment, and economy. Therefore, saving road construction investment costs, improving the quality of asphalt pavement construction, and reducing the impact on the environment have become road Building goals and motivation. At present, new materials and new processes are widely used in the development of road construction. An additive made of waste rubber can well retain the characteristics of rubber powder, improve the comprehensive performance of the road, especially the anti-rutting performance, and is also a waste efficient A good tool to take advantage of. However, the prepara...
