Description

Technical Field

[0001] The utility model relates to the technical field of asphalt preparation, and specifically, to a device for preparing a composite modified asphalt cold filling liquid. Background Technique

[0002] Asphalt cold filling liquid is a new type of material specially used for road maintenance and repair, which is prepared by mixing asphalt, diluent, additives and aggregates in a certain proportion. It is in a liquid or semi-liquid state at normal temperature and has good fluidity and permeability. Among them, the asphalt component provides bonding and waterproof properties to ensure that the repaired road surface can effectively resist water penetration and vehicle loads; the diluent reduces the viscosity of asphalt, making it maintain a good flow state at normal temperature, facilitating the filling of road surface potholes and cracks of various shapes and sizes; additives can improve the performance of cold filling liquid, such as enhancing adhesion, improving anti-aging ability, optimizing low-temperature performance, etc.; aggregates increase the strength and stability of cold filling liquid.

[0003] Compared with traditional hot mix asphalt mixtures, asphalt cold filling liquid does not require heating, which can save energy and construction time and reduce the interference of construction on traffic. It can be constructed in a lower temperature environment and can even be used under wet road surface conditions, with strong applicability. For example, in winter or rainy seasons, when the road is damaged, asphalt cold filling liquid can be quickly put into use to repair the road surface in time and ensure the normal passage of the road.

[0004] In the prior art, the preparation of asphalt cold filling liquid mainly relies on a stirring kettle and a conveying structure. The function of the stirring kettle is to fully stir and mix asphalt, diluent, additives and aggregates at the same time, and then output through a delivery pump. However, in view of the fact that the processing temperatures of different raw materials (such as diluent, additives, etc.) after being added to the stirring kettle are different, it is necessary to repeatedly adjust and control the processing temperature of the stirring kettle, and it is difficult to quickly adapt to the processing requirements when different raw materials are added.
