Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to a novel ultra-thin layer epoxy grafted high-viscosity asphalt production device. Background Art

[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is in liquid state, black on the surface, and soluble in carbon disulfide. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. In the existing technology, in order to improve the various properties of asphalt, epoxy asphalt is made by adding epoxy resin. Epoxy asphalt is a mixture of epoxy resin, curing agent and base asphalt obtained by complex chemical modification. Compared with ordinary asphalt, it has better performance.

The base asphalt heated to a suitable temperature is fed through the first feeding pipe 13, and the epoxy resin, maleic anhydride and reclaimed rubber in the best ratio are fed through the second feeding pipe 14, and the stirring motor 2 is started to drive the stirring rod 22 and the stirring support rod 221 to rotate for stirring, so as to produce a new type of ultra-thin epoxy grafted high-viscosity asphalt.

[0034] In order to improve the convenience of transmission, refer to Figure 2 and Figure 3 The transmission assembly 5 includes a first transmission bevel gear 51 and a second transmission bevel gear 52 meshing with each other. A transmission cavity 211 is provided in the connecting rod 21. The first transmission bevel gear 51 and the second transmission bevel gear 52 are rotatably arranged in the transmission cavity 211. The stirring rod 22 rotates through the transmission cavity 211. The first transmission bevel gear 51 is coaxially fixedly sleeved on the side wall of the stirring rod 22. The second transmission bevel gear 52 is coaxially fixedly connected with the rotating shaft of the stirring motor 2. After the stirring motor 2 is started, the second transmission bevel gear 52 is driven to rotate, and the meshing drives the first transmission bevel gear 51 to rotate, thereby driving the stirring rod 22 to rotate, and then driving the stirring support rod 221 to stir, and the transmission is convenient and simple.
