来源:http://www.tclqgc.com/ 日期:2025-05-27 发布人:

  在公路建设与养护领域,550冷再生机正以其独特的工艺优势,着道路修复技术的绿色转型。这款设备通过就地再生利用旧沥青路面材料,不仅解决了传统工艺产生的大量建筑垃圾问题,更开创了资源循环利用的新模式。本文将深度解析其工作机理、技术特性及行业价值,揭示这场道路维养领域的革命性变革。

  In the field of highway construction and maintenance, the 550 cold recycling machine is leading the green transformation of road repair technology with its unique technological advantages. This device not only solves the problem of a large amount of construction waste generated by traditional processes by on-site recycling of old asphalt pavement materials, but also creates a new model of resource recycling. This article will deeply analyze its working mechanism, technical characteristics, and industry value, revealing the revolutionary changes in the field of road maintenance.

  一、工作原理:材料循环的精密重构

  1、 Working principle: Precise reconstruction of material cycle

  550冷再生机的核心技术体系由三大系统构成:铣刨破碎系统、添加剂注入系统、混合搅拌系统。在作业过程中,设备以每分钟3-5米的速度前进,铣刨鼓以每秒18-22转的转速对旧路面进行精准切削。其刀具采用硬质合金材质,通过阿基米德螺旋线排列,确保铣刨深度误差控制在±5mm以内,同时将旧料破碎粒径小于37.5mm的级配要求。

  The core technology system of the 550 cold recycling machine consists of three major systems: milling and crushing system, additive injection system, and mixing and stirring system. During the homework process, the equipment advances at a speed of 3-5 meters per minute, and the milling drum precisely cuts the old road surface at a speed of 18-22 revolutions per second. The cutting tools are made of hard alloy material and arranged in an Archimedean spiral to ensure that the milling depth error is controlled within ± 5mm. At the same time, the old materials are crushed to meet the grading requirement of particle size less than 37.5mm.

  添加剂注入系统采用双流体雾化技术,将乳化沥青或泡沫沥青与水按预设比例混合,通过高压泵输送喷嘴。在再生室内部,36个雾化喷嘴呈环形布置,确保添加剂与再生料实现三维立体混合。某高速大修项目数据显示,该技术使添加剂分布均匀性达到92%,远超行业85%的标准要求。

  The additive injection system adopts the dual fluid atomization technology to mix emulsified asphalt or foam asphalt with water in a preset proportion and deliver it to the nozzle through a high-pressure pump. Inside the regeneration chamber, 36 atomizing nozzles are arranged in a circular shape to ensure three-dimensional mixing of additives and regenerated materials. Data from a high-speed overhaul project shows that this technology achieves a uniformity of additive distribution of 92%, far exceeding the industry's standard requirement of 85%.

  混合搅拌系统运用逆流搅拌原理,再生料在搅拌轴作用下形成螺旋运动轨迹,与添加剂进行充分接触。搅拌叶片采用变螺距设计,前段叶片负责快速混合,后段叶片进行精细匀化,使再生混合料的级配波动控制在±3%以内。经检测,再生混合料的空隙率、稳定度等指标均满足JTGF41-2008规范要求。

  The mixing and stirring system uses the principle of counter current stirring, and the regenerated material forms a spiral motion trajectory under the action of the stirring shaft, which fully contacts with the additive. The mixing blades adopt a variable pitch design, with the front blades responsible for rapid mixing and the rear blades for fine homogenization, ensuring that the gradation fluctuation of the recycled mixture is controlled within ± 3%. After testing, the porosity and stability of the recycled mixture meet the requirements of JTGF41-2008 standard.

  二、技术特点:多维度的性能突破

  The dust removal system equipped with the equipment adopts three-stage filtration technology. The primary cyclone separator can remove 90% of large particle dust, the secondary pulse bag filter has a filtration accuracy of 1 μ m, and the final activated carbon adsorption layer has a removal rate of 85% for volatile organic compounds. The actual measurement of a national highway renovation project shows that the PM2.5 concentration in the construction area has been reduced by 78% compared to traditional processes, and the noise level has been controlled below 75 decibels.

  The 550 cold regeneration machine is equipped with an intelligent power matching system that can automatically adjust the engine speed according to the operating load, resulting in a 22% increase in fuel efficiency. Its continuous operation capacity is over 8 hours, and the daily regeneration area can reach 6000 square meters, which is three times more efficient than traditional processes. The equipment transfer time has been shortened to 40 minutes, and the transportation width has been compressed to 3 meters through a hydraulic folding conveyor device, meeting the rapid response requirements of road construction.

  设备可处理不同病害程度的旧路面,对裂缝、车辙、泛油等病害的再生修复率达90%以上。通过调整铣刨深度和添加剂配方,可实现从基层到面层的全结构再生。在某山区公路项目中,成功对15厘米厚的严重车辙路面进行再生,经检测再生层回弹模量达800MPa,满足重载交通要求。

  The equipment can handle old road surfaces with different degrees of damage, with a regeneration and repair rate of over 90% for cracks, ruts, oil spills, and other diseases. By adjusting the milling depth and additive formula, full structural regeneration can be achieved from the base layer to the surface layer. In a mountainous highway project, a 15 centimeter thick severely rutted road surface was successfully regenerated. After testing, the rebound modulus of the regenerated layer reached 800 MPa, meeting the requirements of heavy traffic.

  Compared to traditional excavation and repair techniques, the 550 cold recycling machine can reduce the use of new materials by 60% and lower transportation costs by 40%. The calculation of a major repair project on a certain provincial road shows that cost savings of 280000 yuan per kilometer can be achieved through regeneration construction, and the investment payback period can be shortened to 1.8 years. The equipment maintenance cost is reduced by 35% compared to traditional milling machines, thanks to its modular design and intelligent diagnostic system, with a fault interval mileage of up to 500 hours.

  After on-site testing, the dynamic stability of the recycled mixture reached 8000 times/mm, and the residual strength ratio of water stability reached 85%, both of which were better than the standards of hot mix asphalt mixture. In the runway repair of a certain airport, the standard deviation of the flatness of the regeneration layer was controlled within 0.6mm, meeting the requirements of SMA pavement construction. The 3D intelligent control system equipped on the equipment ensures that the thickness error of the regeneration layer is controlled within ± 3mm.
