Description

Asphalt mixture stirring equipment Technical Field The application relates to the technical field of asphalt processing, in particular to asphalt mixture stirring equipment. Background Asphalt is used as an organic cementing material with excellent waterproof, moistureproof and anticorrosive properties, and becomes an indispensable core base material for road paving, roof waterproof and other engineering in the civil engineering field by virtue of good cohesiveness, stability and durability. In practical engineering application, asphalt is mixed and stirred with mineral materials with different particle sizes and different performances such as broken stone, sand, mineral powder and the like according to a preset proportion to form an asphalt mixture, and the mixing uniformity of the asphalt mixture directly determines the strength, stability and service life of an engineering structure and has a critical influence on the management and control of the subsequent construction quality and the long-term service performance of the engineering. If the mixing is uneven, the local asphalt content of the mixture is easily too high or too low, so that diseases such as pavement cracking, loosening, water seepage and the like are caused, the service life of the engineering is greatly shortened, and the later maintenance cost is increased. In the preparation process of asphalt mixture, the warm mixing technology has become one of the main technologies in the current industry because of being capable of effectively reducing the stirring and paving temperature and reducing the energy consumption and the emission of harmful gas, and the core of the technology is to add a special warm mixing agent in the stirring stage of the mixture, reduce the viscosity of asphalt through the physicochemical effect of the warm mixing agent, break the acting force among asphalt molecules, ensure that the mixture can still maintain excellent construction workability at a lower temperature (usually 30-50 ℃ lower than that of hot-mixed asphalt), and ensure the smooth development of various procedures such as stirring, transportation, paving, compaction and the like. However, the existing asphalt mixing device still has obvious technical defects in the feeding step, most devices adopt a fixed point position feeding mode, materials are directly put into a stirring box from a single fixed position, the materials are easily accumulated in a local area of the stirring box in a concentrated manner, a material agglomeration phenomenon is formed, even if the materials are stirred by a stirring assembly in the follow-up process, the local material concentration difference is difficult to quickly eliminate, the asphalt and mineral materials are difficult to fully contact and fuse, the mixing uniformity of the mixture is finally influenced, and the quality stability of products is reduced. In order to solve the problem of uneven mixing caused by fixed point feeding, the Chinese patent document with publication number of CN115318129B discloses a multidirectional stirring device for asphalt mixture. The scheme mainly includes stirring subassembly, cover subassembly and pan feeding subassembly, through the cooperation of support frame, actuating mechanism and pan feeding subassembly, drives the pan feeding case and makes reciprocating motion along agitator tank length direction, makes the material scatter in the agitator tank body step by step along with the removal of pan feeding case. Compared with the traditional fixed point position feeding mode, the scheme realizes the expansion of the material spreading range, avoids excessive concentrated accumulation of materials to a certain extent, improves the initial uniformity of the asphalt mixture in the stirring process, lays a good foundation for the subsequent stirring process, and further optimizes the final product quality of the asphalt mixture in a certain range. However, as is known from in-depth analysis, the prior art scheme still has room for improvement, and the core problem of uneven material mixing cannot be fundamentally solved. Although the material scattering range is enlarged through the reciprocating motion of the feeding box, the material feeding track is still limited to a local area above the stirring box and is influenced by the comprehensive effects of the granularity, the stacking density and the scattering speed of the materials, the materials are easy to form local drop point concentration due to the action of gravity in the scattering process, so that the material feeding quantity of the local area inside the stirring box is excessive, the material feeding quantity of the local area is insufficient, a new local concentration difference is formed, the difference is difficult to completely eliminate in the subsequent stirring process, insufficient mixing of asphalt and mineral materials still can be caused, and the key performances such as the adhesive strength, the high-temperature
