Carbon-emission-free hot recycled asphalt mixing station

Abstract

The invention discloses a carbon-emission-free hot recycled asphalt mixing station which comprises a mixing station structure bracket, a batching system, an aggregate lifting system, a dehumidification and temperature raising system, a power stirring system, a finished product material storage system and an electric control system; the batching system comprises a plurality of batching bins and a conveyor belt, and the batching bins are arranged in sequence; one end of the conveyor belt extends and penetrates through all the batching bins, and the other end of the conveyor belt is arranged at a lifting bin opening of the aggregate lifting system; a discharge port of the aggregate lifting system is connected with the dehumidification and temperature raising system through a feeding pipe; the dehumidification and temperature raising system comprises an electromagnetic heating module and a microwave heating module which are arranged in sequence; the power stirring system is arranged below the dehumidification and temperature raising system, and a discharge port of the power stirring system is connected with the finished product material storage system. By adopting the microwave heating technology, aggregate can be well heated, the aging phenomenon caused by excessive heating of asphalt is avoided, and the quality of the finished product mixture is well guaranteed.

Description

technical field [0001] The invention belongs to the technical field of maintenance and regeneration of asphalt pavement, and in particular relates to a carbon-emission-free asphalt pavement heat regeneration asphalt mixing station. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Traditional asphalt mixing plants use burners to generate hot air to heat aggregates or RAP materials; the heat source for heating and insulating asphalt also uses burners to heat. The combustion machine uses fossil energy to produce heat. The fossil fuels used in traditional mixing plants include coal powder, heavy oil, diesel, methanol, natural gas, etc. Burning fossil fuels will release toxic gases and a large amount of carbon dioxide, which will pollute the atmosphere and cause unfavorable effects on the environment. Reversed destruction. The temperature of the hot a...

Problems solved by technology

The combustion machine uses fossil energy to produce heat. The fossil fuels used in traditional mixing plants include coal powder, heavy oil, diesel, methanol, natural gas, etc. Burning fossil fuels will release toxic gases and a large amount of carbon dioxide, which will pollute the atmosphere and cause unfavorable effects on the environment. reverse destruction

The temperature of the hot air generated by fuel heating is difficult to control. If the temperature is too high, it will easily cause the aging of the mixture and seriously affect the engineering performance of the asphalt mixture.

Fossil fuels require large storage tanks on site, which poses a greater safety hazard
