Rapid water sample filtering device for environmental monitoring

Abstract

The invention discloses a rapid water sample filtering device for environmental monitoring, which comprises a filtering box, the bottom of the filtering box is fixedly connected with a plurality of supporting legs, the top of the filtering box is connected with a sealing cover, the top of the sealing cover is fixedly welded with a handle, the bottom of the filtering box is connected with a rotating mechanism, and the rotating mechanism is connected with a rotating ring. The inner side wall of the rotating ring is rotationally connected with the inner side wall of the filter box, the rotating ring is connected with a filter screen through a mounting mechanism, the side wall of the filter box is provided with a water outlet, and the inner side wall of the water outlet is fixedly connected with a water outlet pipe. Through cooperative use of the mounting groove, the mounting block, the storage cavity, the telescopic rod, the baffle and the compression spring, rapid replacement of the filter screen is achieved, the problems that in the prior art, impurities are accumulated on the filter screen during filtering, and the filter screen is inconvenient to disassemble and replace are solved, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of laboratory water filtration, in particular to a rapid filtration device for environmental monitoring water samples. Background technique [0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure the status of environmental quality. Environmental monitoring is to determine the level of environmental pollution and environmental quality by monitoring and measuring indicators reflecting environmental quality. [0003] In laboratory testing work, water samples are often filtered. However, the current fast filtering device has a slow filtering speed and a small amount of water to be filtered, and can only filter a small amount of water, which is a waste of time; and the prior art The middle filter screen is inconvenient to disassemble and replace, and the dirt is adsorbed on the filter screen during filtration, which affects the normal use of the filt...

AI Technical Summary

Problems solved by technology

[0003] In the laboratory testing work, water samples are often filtered, but the current fast filtration device has a slow filtration speed, a small amount of water for filtration, and can only filter a small amount of water, which is a waste of time; and the existing technology The medium filter is inconvenient to disassemble and replace, and the dirt is adsorbed on the filter during filtering, which affects the normal use of the filter. Therefore, a rapid filter device for pre-treatment of water samples in environmental monitoring laboratories is urgently needed to solve the problem
