Description

Technical Field

[0001] The utility model relates to the technical field of dredging equipment, in particular to an environmentally friendly dredging device for sludge bottom mud. Background Art

[0002] With the continuous acceleration of urban renewal and the continuous updating of construction concepts, it is necessary to timely update the original and older urban parks. In the process of urban park renovation, environmental dredging equipment must be used to treat the silt in the water body. Usually, environmental dredging equipment includes a flushing and sludge extraction device, which uses the flushing and sludge extraction device to transport the sludge to the mixing pool, add the agent to the pool and mix it with the sludge, and then transport the sludge and agent mixture to the filter bag. The mixed liquid undergoes flocculation reaction to separate the sludge and liquid water. The pollutants in the sludge are solidified together with the sludge in the form of solid particles, and the liquid water is filtered out of the filter bag due to the filtration effect, completing the dredging treatment.

[0003] In traditional environmental dredging equipment, the liquid inlet pipe of the filter bag is set on one side of the filter bag. When the mixed liquid of sludge and reagents is filled into the filter bag, the mixed liquid is easy to accumulate on one side of the pipe mouth, affecting the subsequent transportation of the mixed liquid. In addition, the solid-liquid separation and filtration are completed only by relying on the dead weight of the liquid water. The process is relatively slow, affecting the efficiency of sludge treatment. Utility Model Content

According to the actual solid-liquid separation situation, when the bag body height decreases, the mixed liquid is filled into the filter bag 1 again, and the previous process is repeated repeatedly. According to the actual situation, after filling 8 to 10 times, the height decrease of the bag body is reduced, and the solid content in the filter bag 1 is high. After completing the entire filling process, the filter bag 1 is placed for a period of time to allow the sludge to be fully consolidated.
