Water sample pretreatment filtering device for environmental monitoring laboratory

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.

Description

technical field [0001] The invention relates to the field of environmental monitoring experiments, more particularly, to a pre-treatment and filtering device for water samples in environmental monitoring laboratories. Background technique [0002] Environmental monitoring is to determine the level of environmental pollution and environmental quality by monitoring and measuring indicators reflecting environmental quality. Environmental monitoring includes the detection of water samples. The water sample is filtered to remove the impurities that affect the water quality detection to ensure the accuracy of the water sample detection. However, when the processing and filtering device is processing and filtering the water sample, there are mixed ferromagnetic impurities in the water sample, and the processing and filtering device It is difficult to remove the mixed ferromagnetic impurities, so that the ferromagnetic impurities in the water sample affect the detection effect of th...

[0002] Environmental monitoring is to determine the status of environmental pollution and the level of environmental quality by monitoring and measuring indicators reflecting environmental quality. Environmental monitoring includes the detection of water samples. Water samples are filtered to remove impurities that affect water quality testing to ensure the accuracy of water sample testing. However, when the treatment and filtration device processes and filters water samples, there are mixed ferromagnetic impurities in the water sample, and the treatment and filtration device It is difficult to remove the mixed ferromagnetic impurities, which will cause the ferromagnetic impurities in the water sample to affect the detection effect of the water sample. At the same time, when the ferromagnetic impurities are filtered inside the treatment and filtration device, it is easy to block the filter of the filter plate inside the treatment and filtration device. In the hole, the fluidity of the water sample inside the filter plate is reduced, thereby reducing the effect of filtering other impurities in the water sample
