Description

Technical Field

[0001] This utility model relates to the technical field of monitoring well dredging devices, specifically a monitoring well dredging device for landfills. Background Technology

[0002] Landfills are one of the main methods for disposing of municipal solid waste and some industrial waste. By centrally burying waste and implementing measures such as seepage prevention and pollution control, they effectively reduce the land area occupied by waste and mitigate direct environmental pollution. However, because landfilling generates leachate and potentially harmful substances that can pollute groundwater, landfills must be equipped with monitoring systems to dynamically monitor groundwater quality. Monitoring wells are key facilities for monitoring groundwater quality in landfills. They are typically located around the landfill perimeter and are used to collect groundwater samples to detect the concentration of pollutants and other parameters, helping to assess the landfill's impact on the surrounding environment. Monitoring wells easily accumulate silt, waste residue, and other sediments. The presence of this silt can not only block the well channels but also distort sampling results, thus affecting the accuracy of monitoring data and preventing a comprehensive assessment of the true condition of the groundwater. Therefore, it is necessary to clean the silt from the monitoring wells.

[0003] Patent CN217105287U discloses a groundwater monitoring well dredging device with stirring function, including a dual-shaft motor. A reducer is provided on the rotating shaft at the lower end of the dual-shaft motor to drive the stirring paddle. The outer shell is connected to an annular bracket. A circular fixed upper shell is provided above the dual-shaft motor. A water inlet is provided between the fixed upper shell and the dual-shaft motor. At least one booster impeller is provided on the rotating shaft at the upper end of the dual-shaft motor. The booster impeller is located inside the fixed upper shell. A water outlet is provided on the upper part of the fixed upper shell. A waterproof wire and a lifting ring are located at the top.

[0004] The aforementioned existing technology uses an agitator to stir the sediment deposited in the monitoring well, forming a mixture of sediment and water. This mixture flows into the inlet and is propelled into the outlet by a two-stage spiral impeller mounted on an upward-facing shaft at high speed. However, this technology has certain drawbacks: the inlet is easily clogged by large impurities, especially when there are large particles of garbage or other solid debris in the monitoring well. Multiple inlets may be blocked simultaneously, making dredging difficult. To solve the clogging problem, the dredging device often needs to be removed and manually cleaned, which not only increases the complexity of the operation but may also reduce the dredging efficiency. Therefore, we propose a dredging device for monitoring wells in landfills. Utility Model Content

[0005] The purpose of this invention is to provide a dredging device for monitoring wells in landfills to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A landfill monitoring well dredging device includes a mixing component. The mixing component includes a mounting box. A motor is installed at the bottom of the inner wall of the mounting box.
