Water sample pretreating device

Abstract

The invention discloses a water sample pretreating device which comprises a box body, a water inlet pipe, an overflow pipe, a water draining pipe, a backwashing pipe, a mixer, a filter and a sampling pipe, wherein the box body comprises a pretreating cover and a pretreating box, the pretreating cover is fixedly connected with the pretreating box by virtue of a bolt; the filter and the mixer are both fixedly arranged on the pretreating cover and extend into the pretreating box; the mixer comprises a motor and a mixing knife, the motor is in driving connection with the mixing knife; the water inlet pipe is positioned at the lower end of the left side of the pretreating box, the overflow pipe is positioned at the upper end of the left side of the pretreating box, the water draining pipe is positioned in the middle of the bottom of the pretreating box; the backwashing pipe is fixedly arranged on the filter and extends into the filter; the sampling pipe is positioned on the filter and extends into the lower end of the filter. The water sample pretreating device has the characteristics of preventing permeation and leakage and preventing corrosion and is easy to maintain, and can be used for effectively improving the water sample treating efficiency, prolonging the cleaning and maintaining period and reducing the cleaning and maintaining difficulty.

Description

Technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a water sample pretreatment device. Background technique [0002] Currently, water quality online monitoring instruments are basically made of precision parts, but due to the complicated conditions of the water samples being monitored, impurities such as suspended particles in the water samples can easily block the precision instrument pipelines. At present, most of the existing water sample pretreatment devices on the market only have the functions of sedimentation and filtration, leading to many shortcomings such as unrepresentative analysis of water samples, easy pollution, and difficult cleaning and maintenance. Summary of the invention [0003] The purpose of the present invention is to provide a water sample pretreatment device to solve the above-mentioned problems in the background art. [0004] In order to achieve the above objectives, the present invention ...
