Water sample pretreatment device for environmental monitoring laboratory

Abstract

The present invention relates to a water sample pretreatment device for an environmental monitoring laboratory. The device comprises an air compressor pump; the outlet of the air compressor pump is connected to the inlet of a water storage tank; an outlet pipe of the water storage tank is connected to a sediment cleanup device; and the sediment cleaning device includes a closed filter barrel. A water sample is injected into the water storage tank, the air compressor pump pressurizes the water storage tank to inject the water in the water storage tank into a filter screen barrel through the outlet pipe; a motor drives the filter screen barrel to rotate, and under the action of centrifugal force, the water injected into the filter screen barrel is thrown out; the thrown water falls onto a spacer plate, and penetrates through a Raschig ring filling material to a water storage chamber of a filter barrel below the separator plate; and water sample sampling is carried out by a water outlet in communication with the water storage chamber. The water sample pretreatment device for the environmental monitoring laboratory has simple structure; due to the rotary filter screen barrel and Raschig ring filling material with less resistance, the filtering is quick; a water outlet filter is arranged on the water outlet pipe; and three stages of filtration can quickly filter the water sample and has ideal filtering effect.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to an environmental monitoring laboratory water sample pretreatment device for processing water samples. Background technique [0002] At present, laboratories often need to test water samples, especially environmental monitoring departments and environmental testing institutions. The detection of water samples can determine the organic matter and its inorganic salts in the water body, especially the content of heavy metals, which is of great significance for water body monitoring. [0003] Laboratory testing of water samples requires precise and expensive instruments and equipment. If the size of impurities in the water sample is large, it will cause damage to the equipment. Therefore, the current water sample monitoring needs to filter the water sample to remove solid particles and impurities in the water sample. However, the existing water sample treatment equip...
