Description

Technical Field

[0001] This utility model relates to the field of asphalt production technology, and in particular to an energy-saving and environmentally friendly mixing device for SBS modified asphalt production. Background Technology

[0002] SBS (styrene-butadiene-styrene) modified asphalt, due to its excellent comprehensive properties such as improved rutting resistance, crack resistance, and durability, has become the main type of modified asphalt used in road engineering. However, traditional SBS modified asphalt production mixing devices may have mixing dead zones, affecting the uniformity of mixing. For example, Chinese patent disclosure "An Asphalt Production Mixing Device" (application number: 202322699402.2) describes a mixing drum filled with asphalt. The rotating disc drives the mounting columns to rotate, and the asphalt around the mounting columns moves upward with the rotation of the disc. The upward-moving asphalt is constrained by the baffle and moves through the protrusions between adjacent columns to the outside of the guide cylinder. It then falls due to gravity and moves upward again through the gaps between the mounting columns with the screw rod, thus circulating and improving mixing efficiency. However, mixing dead zones may still exist at the edges and bottom of the mixing drum, which may affect the mixing quality. Utility Model Content

The output end of the motor B10 is fixedly connected to the rotating shaft 11 to connect the motor B10 and the stirring plate 13 and transmit power. The rotating shaft 11 passes through the lower surface of the mixing tank 1. The end of the rotating shaft 11 away from the motor B10 is fixedly connected to a bottom plate 12 to support the stirring plate 13. The upper end of the rotating shaft 11 is fixedly connected to the lower surface of the bottom plate 12. The stirring plate 13 is fixedly connected to the upper surface of the bottom plate 12 to promote the mixing of materials inside and outside the mixing tank 1.

[0025] A top plate 15 is fixedly connected to the upper surface of the mixing plate 13 to ensure the stability of the mixing plate 13. The top plate 15 is annular, and the auger 9 passes through the center of the top plate 15. A limiting groove is provided on the inner side wall of the mixing tank 1 to limit the movement of the side surfaces of the bottom plate 12 and the top plate 15.
