Screening device for drilling fluid additive production

The utility model relates to a screening device for drilling fluid additive production, and belongs to the technical field of drilling fluid additive production equipment. According to the technical scheme, the screening device for drilling fluid additive production mainly aims at solving the problems that some existing screening devices usually can only conduct fixed screening according to the mesh size of screening nets of the screening devices, so that the mesh size of the screening nets of the screening devices cannot be changed according to the needed particle size, and then practicability is not high. Comprising a damping base and a conveying mechanism, and a vibration column is movably sleeved with the damping base. Through the design of the structures such as the blanking opening, the screening net, the metal clamping frame and the vibration motor, the screening net is directly moved upwards through the blanking opening, then the screening net drives the metal clamping frame to be separated from the s
