The invention relates to the technical field of demulsifier production, in particular to a filter with a particulate matter separation function for oil field demulsifier production. The technical problems that separated particle impurities are inconvenient to discharge out of a filtering device, normal use of the filtering device is reduced, and the filtering efficiency of a demulsifier is reduced are solved. According to the technical scheme, the filter with the particulate matter separation function for oil field demulsifier production comprises a supporting shell, a feeding mechanism, a vibration filtering mechanism and the like, the inner side face of the bottom of the supporting shell is provided with a protrusion, the feeding mechanism is arranged above the supporting shell, and the vibration filtering mechanism is arranged on the upper portion of the inner side face of the supporting shell. By designing the feeding mechanism, non-uniform discharging of an oil field demulsifier caused by different pressures of the oil field demulsifier to the bottom of the material containing shell is avoided, by designing the vibration filtering mechanism, the filtering efficiency of the sieve plate is improved, and meanwhile, the situation that too many impurity particles are accumulated, and filtering holes in the sieve plate are blocked is avoided.
