The invention discloses a portable dredging pump for groundwater environment monitoring wells, which comprises a housing, a connecting pipe, a motor, a gearbox, a top cover, an output hole, an inner cavity, an impeller, a water suction hole, a filter screen, and a double transmission. Device, silt discharge joint, inner cavity two, impeller two, annular cavity, water outlet hole, conveying hole, gap, spiral piece, cutting piece, communicating hole and communicating cavity, etc.; the present invention has the advantages of reasonable and simple structure, low production cost and convenient installation , the function is complete, the rotation of the motor here will also drive the spiral piece to rotate through the transmission shaft, so that the silt at the bottom of the well can be directly transported upwards, which improves the efficiency of silt cleaning; The work of diluting the silt to avoid clogging the impeller 2 also improves the reliability and stability of silt cleaning; in the present invention, the rotation of the cutting blade can break up the agglomerated silt, thereby further avoiding the clogging and improving the reliability of cleaning and stability.
Description
technical field [0001] The invention relates to the technical field of groundwater environment monitoring well equipment, in particular to a special dredging pump for portable groundwater environment monitoring wells. Background technique [0002] With the development of my country's social economy, the problem of groundwater environment has become increasingly prominent, and groundwater in some areas has been seriously polluted. It is becoming more and more important to conduct scientific and accurate investigation, evaluation and treatment of polluted groundwater. Because the groundwater environment monitoring well water will precipitate solid particles under long-term standing, which will precipitate into silt at the bottom of the well. During the groundwater dredging work, the silt at the bottom of the well will be disturbed, resulting in floating solid particles in the extracted groundwater samples. Affect the quality and validity of groundwater quality testing results...
