The invention discloses a byproduct
recovery device for disperse red 60 preparation. According to the technical scheme, the byproduct
recovery device comprises a main extraction tank, a mounting plate and a main discharging
pipe are fixedly connected to the bottom of the main extraction tank, a secondary extraction tank is fixedly connected to the mounting plate, and a first valve is fixedly connected to the main discharging
pipe; the device comprises a main extraction tank, a main
discharge pipe is arranged at the bottom of the main extraction tank, a first
branch pipe is fixedly connected to the position, close to the top end, of the main
discharge pipe, the first
branch pipe is fixedly connected with a secondary extraction tank, and a second valve is fixedly connected to the first
branch pipe. According to the device, the
solvent at the junction of the liquid level after extraction can be completely discharged into the secondary extraction tank for secondary extraction, the phenomenon that the upper and lower solvents are mixed can be effectively reduced, the extraction quality is improved, meanwhile, the secondary extraction process and the subsequent primary extraction of the mixed liquid can be synchronously carried out, and the overall
recovery efficiency is not influenced.
