Movable-type cold in-plant recycling machine

Abstract

The invention relates to a movable-type cold in-plant recycling machine. The movable-type cold in-plant recycling machine is characterized in that a vehicle frame is hauled for transition by a tractor. A power plant, a hydraulic system, a water tank and a fuel tank are arranged at the front end of the vehicle frame. A material storehouse is arranged on an aggregate conveying device. A cement conveying device, a stirring device and an unloading belt conveyor are arranged on the vehicle frame in sequence. A foaming asphalt adding device is arranged on the stirring device. An emulsified asphalt spraying nozzle and a mixing water nozzle are arranged at the feeding end of the stirring device. The aggregate conveying device, a cement lifting device, the cement horizontal conveying device and theunloading belt conveyor are driven by a hydraulic motor to complete conveying of ingredients and mixtures. New and old aggregates, cement, asphalt and water enter the stirring device in proportion through the conveying devices. The evenly stirred asphalt mixtures are output by the unloading belt conveyor. The movable-type cold in-plant recycling machine has the characteristics of being compact instructure, high in maneuverability, small in turning radius, convenient and flexible in transition and the like, is suitable for construction operation of being dispersed in construction sites and small in scale of the quantity of recycled materials, and solves the problem of using the recycled old materials to produce the asphalt mixtures in a field.

Description

technical field [0001] The invention belongs to the field of road engineering machinery, and mainly relates to a mobile factory-mixed cold recycling machine which can use recovered old materials to produce asphalt mixture at the operation site. Background technique [0002] With the rapid development of highway construction in our country and the need for renovation and reconstruction of a large number of asphalt pavements of high-grade highways, the recycling of old asphalt pavement materials has been re-emphasized and widely concerned. At present, only in major and medium maintenance projects of trunk roads in my country, more than 160 million tons of asphalt pavement waste materials are produced every year, and the recycling rate of pavement materials is less than 30%, which is far lower than the utilization rate of more than 90% in developed countries. The Ministry of Transport also clearly stated that by 2020, the recycling rate of old road materials in the country will...

AI Technical Summary

Problems solved by technology

Most of the currently used asphalt mixing equipment is intermittent large-scale fixed equipment. The main problems are incoherent discharge and low production efficiency. In addition, the shortcomings of large models, large floor space, and time-consuming and laborious migration make it suitable for The performance is limited, which hinders the improvement of the recycling rate of road pavement old materials
