Asphalt mixing station with heat preservation layers

Abstract

The invention discloses an asphalt mixing station with heat preservation layers. The asphalt mixing station comprises a cold aggregate supply system, a belt conveyor, a drying drum, a dust remover, a hot aggregate elevator, a hot aggregate screening device, a hot aggregate storage cabin, an aggregate weighing device, an asphalt supply system, a product stock bin, a powder stock bin and a stirrer, wherein the hot aggregate elevator is provided with a heat preservation layer I; the hot aggregate screening device is provided with a heat preservation layer II; the hot aggregate storage cabin is provided with a heat preservation layer III; the aggregate weighing device is provided with a heat preservation layer IV; and the stirrer is provided with a heat preservation layer V. According to the asphalt mixing station disclosed by the invention, the technical characteristics of original asphalt mixing station are kept invariable; the added transformed heat preservation layers are simple in structure, ingenious and economical; and the asphalt mixing station is good in heat preservation effect; the energy loss of hot aggregates can be reduced; the influences on personnel caused by that heat diffuses around the mixing station are avoided; meanwhile, fuel can also be saved; the construction cost is reduced; and the asphalt mixing station has the energy-saving, environment-friendly effects, and is high in practicability, good in using effect and convenient to popularize and use.

Description

【Technical field】 [0001] The invention belongs to the technical field of engineering machinery, in particular to an asphalt mixing plant with a thermal insulation layer. 【Background technique】 [0002] Asphalt mixing plant, also called asphalt concrete mixing plant, is a complete set of equipment for producing and mixing various asphalt mixtures. It is suitable for construction departments such as highways, urban roads, parking lots, and docks. The primary cold aggregate is dried and heated by countercurrent heating in the drying drum to become hot aggregate. The heating temperature is generally 160-180°C. The material storage bin and the aggregate weighing device enter the mixer, and mix with the added mineral powder and hot asphalt to obtain the asphalt mixture. If the hot aggregate elevator, hot aggregate screening device, hot aggregate storage bin, aggregate weighing device and mixer are not insulated, the hot aggregate will lose a lot of heat on the way out of the dryi...

AI Technical Summary

Problems solved by technology

If the hot aggregate elevator, hot aggregate screening device, hot aggregate storage bin, aggregate weighing device and mixer are not insulated, the hot aggregate will lose a lot of heat on the way out of the drying drum, On the one hand, it causes energy loss; on the other hand, heat is lost to the surrounding of the mixing station, which also affects personnel

Especially if the energy loss is serious, the fuel consumption is very high, which not only increases the construction cost, but also does not save energy and protect the environment.
