沥青脱桶设备

DJT4 asphalt melting equipment

DJT4型沥青脱桶装置以导热油为载热体，通过加热盘管和导热油炉废气余热对沥青进行加热、熔化、脱桶、脱水。该装置可保证沥青加热质量，具有热效率高、沥青脱桶速度快、改善劳动强度、减少污染等特点。

DJT4 asphalt melting equipment attached developed by us uses conduction oil as heating medium to heat, melt, dump and dewater asphalt with heating coil and conduction oil boiler exhaust gas waste heat. The equipment can ensure asphalt heating quality, and features high thermal efficiency, quick asphalt dumping, low labor intensity and less pollution.

DJT4型沥青脱桶装置主要由脱桶箱体、龙门机构、装桶台车及电器控制系统等部分组成。箱体分上下两室，上室为桶装沥青熔化室，四周均布有加热盘管，加热管与沥青桶主要以热废气换热及辐射方式换热，达到沥青脱桶的目的；两条导轨，为装桶台车进出的轨道。下室主要是将桶中脱出的沥青继续加热，使温度达到吸泵温度（120℃），然后由沥青泵泵出使用， 如果延长加热时间可获得更高的温度（160℃）。起吊龙门机构采用卷扬机提起或放下箱体门。装桶台车通过驱动装置使台车在导轨上进出箱体。工作开始时，首先转动卷扬机打开上箱体门，驶出台车，装满沥青桶，然后台车驶入箱体，关上箱体门，进行加热、脱桶。脱桶结束时吊起箱体门，驱动台车，运出并卸下空桶，重新装入新桶，重复上次加热、脱桶。

DJT4 asphalt melting equipment mainly comprises of the dumping box, gantry, barrel bogie and electrical control system. The box includes upper and lower chambers; the upper chamber is for barreled asphalt melting with heating coil around. Asphalt dumping is mainly realized by hot exhaust gas heat exchange and radiation exchange between the heating coil and asphalt barrel. Two rails are provided for barrel bogie in and out. The chamber is designed to heat the asphalt dumped from the barrel further to the pump suction temperature (120℃) so that the asphalt can be pumped out by the pump. If the heating time is extended, a higher temperature (160℃) can be reached. The gantry is provided with a hoist to lift or lower the box door. The barrel bogie is driven by a drive unit to move in and out of the box. To start the work, operate the hoist to open the upper box door, drive out the bogie and load it with asphalt barrels, then drive the bogie into the box, close the box door for heating and dumping. When dumping is finished, lift the box door; drive the bogie to carry out unloading the empty barrels and load new barrels, repeat heating and dumping as previous.
