The invention discloses a suspending type liquid phase mixing and stirring device. A barrel cover comprises a first barrel cover and a second barrel cover, wherein the first barrel cover is fixedly connected with a barrel body, and the second barrel cover is arranged on the barrel body; a stirring mechanism is arranged in the barrel body and comprises a second motor, a stirring shaft connected with the second motor and a stirring barrel fixed on the barrel body, the second motor is fixed on the first barrel cover, a plurality of filter ports are formed in the side wall of the stirring barrel,filter cloth is arranged at the filter ports, and the bottom of the stirring barrel is communicated with a first valve arranged on the side wall of the barrel body; a pesticide outlet is formed in theside wall of the barrel body. Stirring and filtration of a pesticide are integrated, the production time is saved, the pesticide is not required to be poured into a filtering device after being stirred in the stirring barrel, accordingly, the common problem that the pesticide is easily spilt in the process is solved, time and labor are saved and the processing efficiency is improved.
