Abstract

The invention relates to the field of vibration screening, in particular to a double-layer drilling fluid vibration screening device. The technical purpose of the invention is to provide the double-layer drilling fluid vibration screening device. According to the technical scheme, a liquid storage tank is fixedly connected to the rear side of the top of the base, a driving mechanism is installed above the screening mechanism, a belt transmission set is installed on the left side of the driving mechanism, and an adjusting mechanism is jointly installed on the right side of the screening mechanism and the top of the base. The drilling mud filtering device has the beneficial effects that the lower screen swings left and right when drilling mud is filtered, a brush is made to scrape and sweep thick mud and clay particles attached to the lower screen, the lower screen is prevented from being blocked by the thick mud and the clay particles, the filtering effect of the lower screen is improved, the thick mud and the clay particles can move forwards along with the drilling mud, and the drilling mud can be well filtered. And automatic discharging of thick slurry and clay particles is achieved, and the cleaning effect is improved.
