Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to a rubber-plastic alloy modified asphalt production device. Background Art

[0002] Modification of base asphalt with scrap tire rubber powder results in poor storage stability and limited improvement in high-temperature performance. Plastic (e.g., polyethylene)-modified asphalt can significantly improve asphalt pavement's rutting resistance and high-temperature resistance, while rubber-modified asphalt can significantly improve its cracking resistance. Combining plastic-modified and rubber-modified asphalts to create alloys can improve both rutting and cracking resistance. Existing asphalt production equipment stirs raw materials within a reaction tank, making it difficult to cut and crush the raw materials during the stirring process. This results in excessively large particle size, which in turn leads to prolonged grinding times. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0018] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figures is inverted, an element described as being "below" another element or feature would be positioned "above" the other element or feature. Thus, the exemplary term "below" can encompass both above and below orientations.
