CN203569415U 一种能减缓沥青老化的沥青混合料欠氧拌和装置 失效 - 放弃

一种能减缓沥青老化的沥青混合料欠氧拌和装置
摘要：
本实用新型公开了一种能减缓沥青老化的沥青混合料欠氧拌和装置，是在搅拌锅侧部连通废气管，所述废气管与第一管道、第二管道形成三通；所述第一管道与沥青拌和站干燥滚筒烟囱连通，所述第二管道与沥青导热油锅炉烟囱连通；在所述第一管道的管路中设有第一引风机、第一截止阀以及去湿机；在所述第二管道的管路中设有第二引风机以及第二截止阀。本实用新型是利用沥青砼拌和站生产时所产生的废气、对沥青砼站拌锅进行预热并改善和缓解沥青混合料拌和时产生的热老化（氧化）现象的一种装置。
摘要（英）：

The utility model discloses an oxygen debt mixing device capable of slowing aging of asphalt for an asphalt mixture. The oxygen debt mixing device is characterized in that the side of an agitator kettle is communicated with a waste pipe, and a tee joint is formed by the waste pipe, a first pipeline and a second pipeline; the first pipeline is communicated with a chimney of a drying roller of an asphalt mixing unit, and the second pipeline is communicated with a chimney of an asphalt conduction oil boiler; a first draught fan, a first stop valve and a dehumidifier are arranged in the pipeline of the first pipeline; a second draught fan and a second stop valve are arranged in the pipeline of the second pipeline. The oxygen debt mixing device is a device capable of preheating the agitator kettle of an asphalt concrete unit by utilizing the waste gas generated during production of an asphalt concrete mixing unit, and improving and slowing the thermal ageing (oxidation) phenomenon generated during mixing of the asphalt mixture.
