The utility model relates to the technical field of raw material recovery, and discloses a raw material recovery device for carbon aerogel preparation, which comprises a cylinder body, one side of the top end of the cylinder body is fixedly connected with a material tank, one side of the top end of the cylinder body is fixedly communicated with a steam pipe, and the middle part of the top end of the cylinder body is fixedly provided with a speed reducing motor; the output end of the speed reduction motor penetrates through the inner wall of the barrel and is fixedly connected with a vertical shaft, stirring blades are fixedly connected to the middle and the bottom of the vertical shaft, a brushing assembly is installed on the surface of the vertical shaft, and a spiral pipe is fixedly connected to the inner wall of the material tank. The brushing assembly comprises two supporting rods, two grooves, two elastic pieces, two connecting rods and a brush. According to the utility model, steam is utilized to preheat a carbon aerogel raw material, heat in the steam can be utilized, more energy is saved, meanwhile, the heating efficiency during distillation is improved, and the inner wall of the recovery device is convenient to clean by utilizing the brushing assembly and the vibration motor.

This invention provides a distillation system for degassing carboxylated styrene-butadiene latex, comprising a polymerization kettle, a distillation column, a condenser, a buffer tank, a mixed-phase feed pump, a conditioning tank, and a vibrating screen. The outlet of the polymerization kettle is connected to the inlet on the side wall of the distillation column. The vapor phase outlet of the distillation column is sequentially connected to the inlet of the polymerization kettle via the condenser, the buffer tank, and the mixed-phase feed pump. The liquid phase outlet of the distillation column is connected to the inlet of the conditioning tank, and the outlet of the conditioning tank is connected to the inlet of the vibrating screen. A fractionation device is provided in the distillation column, comprising several trays. Each tray has multiple valve tubes evenly distributed through it, and each valve tube contains a Tesla valve. A sliding float valve structure is provided at the top of each valve tube. This high-efficiency distillation system can effectively disperse the vapor phase during distillation, allowing for more thorough countercurrent contact between the vapor and liquid phases and more complete interphase mass transfer, thereby further improving the distillation effect and efficiency while reducing energy consumption.
