Counter-flow type hot mix plant regeneration drying roller
The invention discloses a reverse-flow type hot mix plant recycling drying roller, and relates to the technical field of asphalt production equipment. The regeneration drying roller comprises an external drying roller and an internal drying roller, the external drying roller is divided into a fine material guiding area and a mixed material lifting area in the axial direction, and the length of the fine material guiding area is 1/3-1/2 of the total length of the external drying roller; the internal drying roller is coaxially fixed to the fine material guiding area and is divided into a material guiding and screening area and a coarse material lifting area in the axial direction, and the length of the material guiding and screening area is 1/3-1/2 of the total length of the internal drying roller. Asphalt recycled materials are screened into coarse materials and fine materials through the internal drying roller, the coarse materials are in a material curtain state all the time, and the heating efficiency is improved. Fine materials advance along the drum wall of the external drying drum and are mixed and heated with coarse materials in the mixing and lifting area, so that the situation that the fine materials form a material curtain too early is avoided, the situation that the fine materials are sucked away by an induced draft system is reduced, and drum wall adhesion or asphalt aging caused by too early heating of the fine materials is reduced.
本发明公开一种逆流式厂拌热再生烘干滚筒，涉及沥青生产设备技术领域。该再生烘干滚筒包括外部烘干滚筒和内部烘干滚筒，外部烘干滚筒沿轴向上分为细料导料区和混合提料区，细料导料区的长度为外部烘干滚筒总长度的1/3～1/2；内部烘干滚筒同轴固定于细料导料区，内部烘干滚筒沿轴向上分为导料筛分区和粗料提料区，导料筛分区的长度为内部烘干滚筒总长度的1/3～1/2。本发明通过内部烘干滚筒将沥青回收料进行筛分为粗料和细料，使粗料始终处于料帘状态，提高了加热效率。细料沿着外部烘干滚筒的筒壁前进，在混合提料区与粗料混合加热，避免细料过早形成料帘，减少细料被引风系统吸走，减少细料因过早加热而造成的筒壁粘连或沥青老化。
