Abstract
The invention discloses a water sample pretreatment filtering device for an environmental monitoring laboratory, the water sample pretreatment filtering device structurally comprises a water storage tank, a water pump, a water pumping pipe, a filtering device and supporting legs, the upper end of the water storage tank and the right lower end of the water pumping pipe are fixedly mounted in an embedded manner and are communicated with each other, the water pump is mounted at the right lower end of the water pumping pipe, and a magnetic rod magnetically adsorbs ferromagnetic impurities in a water sample; the water sample presses down the top plate under the action of gravity, and the top spring applies reverse elastic force to the top plate, so that the water sample flows back and is ejected upwards, and the effect of removing the ferromagnetic impurities in the water sample is improved; in the swinging process of the outer frame, sliding shafts at the left outer side end and the right outer side end of the outer frame perform arc-shaped guiding swinging in sliding grooves, springs apply repeated elastic force to the sliding shafts, two filtering plates in the outer frame perform ejection filtering on a water sample flowing downwards, and the filtering effect of the filtering plates on other impurities in the water sample is improved; meanwhile, impurities are prevented from being blocked in filter holes of the filter plate.
