The invention discloses rubber asphalt production equipment based on microwave heating, which belongs to the technical field of asphalt production equipment, and includes a microwave heating device and a swelling tank. The microwave heating device includes a microwave resonant cavity for containing rubber powder, a microwave resonant cavity and a waveguide It is connected with the inert gas pipe, which is used to input inert gas while radiating microwaves into the microwave resonant cavity; the outlet of the microwave resonant cavity equipped with a rubber powder stirring mechanism is connected to the swelling tank, and the rubber asphalt in the swelling tank is transported through the pumping system To the vulcanized tube, the vulcanized tube runs through the microwave resonant cavity. The desulfurization activation is realized by microwave radiation in the microwave resonant cavity; the inert gas provides an oxygen-free environment for the activation of the rubber powder to avoid oxidation and spontaneous combustion of the rubber powder; the rubber asphalt flowing through the vulcanization tube is vulcanized by microwave radiation. The invention simultaneously realizes heating desulfurization of rubber powder and heating vulcanization of rubber asphalt through microwaves, simplifies the production process, reduces equipment cost investment, and improves the production efficiency and quality of rubber asphalt.
Description
technical field [0001] The invention belongs to the technical field of asphalt production equipment, and in particular relates to a rubber asphalt production equipment based on microwave heating. Background technique [0002] Asphalt rubber is to first process waste tires into rubber powder, and then combine them according to a certain thickness and gradation ratio. Modified asphalt cementitious material formed after sufficient swelling reaction with base asphalt. [0003] As we all know, one of the raw materials for the production of rubber asphalt is rubber powder, which is to cut waste tires into strips, cut into pieces, and grind them into rubber powder. It is difficult to evenly disperse a large amount of rubber powder in the asphalt by simple thermal energy and mechanical energy. The conventional method is to first desulfurize the rubber powder in a special desulfurization equipment, and then add the desulfurized rubber powder to the asphalt mixed with additives for ...
