Problems solved by technology

These technical measures can restore the comprehensive performance of the pavement, but they will generate a large amount of waste pavement materials, which contain a large amount of asphalt and concrete materials. At present, there are often phenomena such as random stacking or backfilling of waste pavement rubbish after construction, making waste materials Pollution to the environment, but also a lot of waste of resources

Embodiment 1

[0046] The waste pavement asphalt recycling system includes a feeding mechanism 1, and an asphalt separation device 2 is arranged downstream of the feeding mechanism 1, and the asphalt separation device 2 is used to receive the road surface waste materials from the feeding mechanism 1 and realize the cleaning of the road surface. For the preliminary separation of waste materials, an asphalt deep processing line 3 and a crushed stone recovery treatment line 4 are respectively installed in parallel downstream of the asphalt separation device 2. The asphalt deep processing line 3 is used to further process and recycle the separated asphalt to form a spare asphalt block , the crushed stone recycling line 4 is used to recover the separated crushed stones.

[0047] This system is mainly for the separation of asphalt and gravel and the subsequent recycling and classification of the waste pavement materials that have been initially crushed. The larger pieces of material are crushed ag...

Embodiment 2

[0062] Example 2: The difference from Example 1 is:

[0063] Preferably, the shredding assembly 12 includes two shredding rollers 1201 arranged in parallel and spaced apart in the shredding barrel 11 . There are a number of crushing knives 1202, and the crushing knives 1202 arranged opposite to each other on the two crushing rollers 1201 are alternately arranged, and a communicating crushing material is symmetrically arranged on the side walls of the crushing cylinder 11 at both ends of each crushing roller 1201. The inner and outer laterally elongated holes 1203 of the cylinder 11 are provided with a displacement adjusting assembly 6 on the outer sidewall of each laterally elongated hole 1203 outside the crushing cylinder 11 respectively, and the two ends of the crushing rollers 1201 pass through respectively The horizontally elongated holes 1203 at the corresponding positions pass through the crushing barrel 11 and are respectively movably matched with the displacement adjus...

Embodiment 3

[0067] Example 3: The difference from Example 2 is:

[0068] Preferably, the crushed stone stirring member 23 includes a steel cylinder 2301 that is fixedly inserted in the upper cavity of the central melting cavity 22, and a fixing ring 2302 is arranged in the central melting cavity 22 below the steel cylinder 2301 to be coaxial with it. Between the steel cylinder 2301 and the fixing ring 2302, a number of steel columns 2303 are evenly spaced along the circumferential direction. The upper and lower ends of the steel columns 2303 are welded to the bottom of the steel cylinder 2301 and the top of the fixing ring 2302 at the corresponding positions respectively. On the side wall of each steel column 2303 facing the center side of the central melting cavity 22, a number of feeding teeth 2304 are welded from top to bottom, and the upper end of the steel cylinder 2301 protrudes from the central melting cavity 22 and is welded firmly. Connect a hollow steel gear 2305 coaxially arran...

Abstract

The present application relates to the field of highway environmental protection construction, in particular to a comprehensive station that efficiently recycles and utilizes waste pavement asphalt and completes the classification and treatment of materials, especially a waste pavement asphalt recycling and processing system, including a feeding mechanism, and a downstream of the feeding mechanism is provided with a Asphalt separation device, the asphalt separation device is used to receive the pavement waste materials from the feeding mechanism and realize the preliminary separation of the processed pavement waste materials. A bitumen deep processing line and a crushed stone recycling process are respectively arranged in parallel downstream of the asphalt separation device. An assembly line, the asphalt deep processing assembly line is used to further process and recycle the separated asphalt to form spare asphalt blocks, and the crushed stone recovery treatment assembly line is used to recover the separated crushed stone. The crushed asphalt concrete pavement material can be quickly recovered, classified and reused to reduce the generation of road construction waste, and the whole system can effectively improve the recovery effect when used.

Description

technical field [0001] The present application relates to the field of highway environmental protection construction, in particular to a comprehensive station that efficiently recycles and utilizes waste pavement asphalt and completes the classification and processing of materials, especially a waste pavement asphalt recycling and processing system. Background technique [0002] Asphalt pavement is the main type of highway pavement in my country. The structural performance of the asphalt pavement will gradually deteriorate with the repeated action of the driving load and the change of the environmental conditions, and early damage will occur, especially for some heavy-duty trucks, the asphalt pavement often bears heavy load pressure, which makes the asphalt pavement appear. Subsidence, rutting, cracking, slipping, crowding and other conditions, once the damage occurs in the later stage and then through the rain and snow weather and other bad weather conditions continue to ca...
