TECHNICAL FIELD

[0001] The utility model relates to water sample pretreatment device technical field, specifically for water quality monitoring water sample pretreatment device. BACKGROUND

[0002] Water quality monitoring equipment is an important tool for real-time monitoring and evaluating water environmental quality. In order to ensure the accuracy and reliability of monitoring data, water samples usually need to go through a series of pretreatment steps before entering the monitoring equipment. Through pretreatment, the interference of various components in the water sample can be reduced, thereby improving the accuracy and reliability of the detection results, and avoiding the damage of harmful components such as silt and suspended solids in the water sample to the detection instrument, prolonging the service life of the instrument.

[0003] The existing pretreatment device realizes the purpose of pretreatment by multi-stage filtering and sand settling of water samples. Due to the characteristics of static sand settling, suspended solids and impurities such as silt are easily attached in the water tank, which needs to be cleaned manually and is difficult to clean. At the same time, some suspended solids cannot be completely precipitated in the sedimentation tank, which can easily cause blockage, wear and tear of the detection instrument pipeline.

[0025] Reference Figures 1-4 , the embodiment provides a water sample pretreatment device for water quality monitoring. The fluidization component 3 solves the problem that suspended solids cannot be completely precipitated in the sedimentation tank, which easily causes pipeline blockage, wear and other damage to the detection instrument. The device comprises a pre-treatment water tank 1, a cover plate 2 is rotatably installed on the pre-treatment water tank 1, opening the cover plate 2 facilitates replacement of the fluidization component 3, a water inlet pipe 21 is fixedly installed on the pre-treatment water tank 1, the inlet direction of the water inlet pipe 21 is directed to the bottom of the pre-treatment water tank 1, and the bottom deposits sludge and other impurities during the water sample sampling process, which has a flushing effect. At the same time of flushing the water tank, the ultrasonic vibrator 61 is turned on, which can effectively clean the pre-treatment water tank 1. A sewage pipe 6 is fixedly installed in the pre-treatment water tank 1 and communicates with the pre-treatment water tank 1, which is used to discharge the precipitated suspended solids. An ultrasonic vibrator 61 is fixedly installed on the pre-treatment water tank 1. A drain pipe 7 is installed on the pre-treatment water tank 1 and communicates with the pre-treatment water tank 1, which is used to discharge the filtered water. Two groups of overflow pipes 71 are installed in the pre-treatment water tank 1 and communicate with the outside of the pre-treatment water tank 1, which can ensure that the pre-treatment device continuously processes real-time water samples. A fluidization component 3 is installed in the pre-treatment water tank 1 to make the suspended solids completely precipitate. A collection device 4 is installed on the fluidization component 3 to avoid pipeline blockage. A filtering device 5 is installed in the pre-treatment water tank 1 to filter the water source. Through the arrangement of the fluidization component 3, the water sample is in a fluid state in the pre-treatment water tank 1, and the removal of suspended solids, sand and other impurities is realized during the water sample flow process.

[0026] The fluidization component 3 includes a quadrilateral plate 31 slidingly installed in the pretreatment water tank 1, a plurality of groups of honeycomb grooves 32 are uniformly arranged in the quadrilateral plate 31, the component form includes but is not limited to the honeycomb grooves 32 and the inclined plate structure, and meanwhile, corresponding diameters, angles and other parameters can be adapted according to different water sample states on site. An L-shaped support frame 33 used in cooperation with the quadrilateral plate 31 is fixedly installed in the pretreatment water tank 1 and can support the quadrilateral plate 31. A handle 34 is fixedly installed on the quadrilateral plate 31 and the component can be taken out through the handle 34, so that the cleaning and maintenance and component replacement operation of the component on site are facilitated. The water sample is discharged into the pretreatment water tank 1 through the water inlet pipe 21, and the water flows along the direction of the honeycomb grooves 32 on the quadrilateral plate 31, so that the suspended solids, sand and other impurities are removed in the process of flowing, and the situation that the suspended solids cannot be completely precipitated in the sedimentation tank and easily cause damage such as pipeline blockage and wear of the detection instrument is avoided.

[0027] Embodiment two

[0028] On the basis of the embodiment one, the technical solution proposed in the embodiment one is used to solve the shortcoming that the suspended solids cannot be completely precipitated in the sedimentation tank and easily cause damage such as pipeline blockage and wear of the detection instrument.
