Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, in particular to a stirring device for rubber asphalt production which is convenient for heat preservation. Background Art

[0002] Rubber asphalt is a new type of pavement material made by mixing rubber materials such as waste tires with asphalt. It has advantages such as wear resistance, pressure resistance, crack resistance, and anti-slip properties. With the increasing awareness of environmental protection and the reuse of resources, rubber asphalt production technology has been widely used. During the rubber asphalt production process, a stirring device is required to stir and mix the rubber asphalt.

[0003] An existing mixing device for rubber asphalt production that is easy to keep warm may have the following disadvantages: the inner wall is difficult to clean. Since the inner wall structure of the heat-insulating mixing device may be complex and there are many hard-to-reach dead corners, cleaning becomes difficult. In particular, when the asphalt mixture adheres to the inner wall during the mixing process, if it is not cleaned in time, it may affect the mixing effect and product quality; the mixing uniformity is insufficient. If the mixing blades of the mixing device are unreasonably designed or insufficient in number, the asphalt mixture may be unevenly mixed, affecting the product quality.

[0004] Therefore, we propose a stirring device for rubber asphalt production which is convenient for heat preservation. Utility Model Content

[0005] The purpose of the utility model is to provide a stirring device for rubber asphalt production that is easy to keep warm, so as to solve the problems of difficulty in cleaning the inner wall and insufficient stirring uniformity proposed in the above background technology.

The height and position of the base plate can be conveniently adjusted by extending and retracting the cylinder, thereby facilitating installation and disassembly.

[0010] Preferably, the scraper blade 1 and the scraper blade 2 are triangular in shape, and the pointed corners of the scraper blade 1 and the scraper blade 2 are facing the inner wall of the mixing barrel. The design of the pointed corners facing the inner wall of the mixing barrel can enable the scraper to scrape the inner wall of the mixing barrel more effectively during the mixing process, thereby reducing the adhesion of materials in the mixing barrel and improving the mixing efficiency.

[0013] Preferably, the outlet is fixedly connected to the right side of the mixing barrel at a certain angle. The design of the outlet at a certain angle can make it easier to discharge the material from the mixing barrel, thereby reducing the labor intensity of the operator and improving production efficiency.

[0014] Preferably, the baffle is fixedly connected to both sides of the feed box at a certain angle. The design of the baffle being tilted at a certain angle can guide the material to flow in a specific direction, avoiding the formation of dead corners or accumulation of materials inside the feed box, thereby optimizing the flow effect of the material.

[0017] 2. This mixing device for rubber asphalt production is easy to keep warm. The material enters the feed box through the filter plate. The filter plate can effectively remove impurities and particles in the material to ensure the purity of the material, thereby improving the quality of the rubber asphalt. The design of the feed box allows the material to be mixed evenly, avoiding material accumulation and local overload, and further improving the mixing effect. BRIEF DESCRIPTION OF THE DRAWINGS
