The application discloses a device for recycling asphalt in waste asphalt mixture, which comprises a main box body, a bottom plate fixed to the lower side of the main box body, a bottom frame fixedly connected to the lower side of the bottom plate for supporting, a feeding hopper fixedly installed at the top rear side of the main box body, and a cooling and conveying mechanism arranged in the main box body for cooling and conveying the asphalt mixture. The cooling and conveying mechanism is used for uniformly cooling the asphalt mixture to zero below, so that the asphalt material becomes brittle and fragile, and the stone material still maintains the original strength at low temperature due to the material characteristics. The extrusion mechanism uses an elastic rotating structure to apply controllable extrusion force to the mixture, the brittle asphalt material is preferentially crushed, and the stone material is hardly damaged in the extrusion process and can fall into a stone collecting hopper in an intact form. The device greatly improves the recycling rate of the stone material, the intact stone material can be directly used for road base or concrete aggregate, and secondary processing is not needed, so that the cost of stone purchase and reprocessing is remarkably reduced.

The utility model provides an energy-saving acidizing blocking remover preparation and recovery device, which relates to the field of acidizing blocking removers and comprises a preparation unit, a recovery unit is arranged at the bottom of the preparation unit, and an exhaust component is arranged at the top of the preparation unit. The rotating speed of the gear motor can be controlled through the microcontroller, heat is directly transferred to raw materials through the electric heating tube, and the heat preservation sleeve can effectively reduce loss of heat in the reaction tank and reduce energy consumption in the heating process, so that the energy utilization efficiency is improved, the energy consumption is reduced, and the purpose of saving energy is achieved. The recycling unit is arranged at the bottom of the preparation unit, so that the integrated design of preparation and recycling of the acidification blocking remover is realized, the occupied area of equipment and the loss in the material transfer process are reduced, the production efficiency is improved, the used acidification blocking remover can be effectively separated and purified through a nanofiltration membrane and an ultrafiltration membrane, the recycling rate of effective components is improved, and the production cost is reduced. The production cost is reduced.
