A sewer dredging device and its application method

Abstract

The invention relates to a sewer dredging device which belongs to the technical field of dredging. The sewer dredging device provide by the invention has high adaptability, wherein water is supplied by a water pump and high-pressure water columns are sprayed out by a sprayer, so that the sewer wall can be washed from top to bottom, and thus sludge left on the sewer wall can be washed. In this way, the defect that the sludge on the sewer wall cannot be cleaned up by a suction dredging method can be solved. According to the invention, compressed air is taken as a dredging medium; huge impact force is generated by the blasted-in compressed air; the sludge on the sewer bottom can be impacted and stirred violently; the sludge on the bottom can be lifted by washing and will be lifted along the bottom face of a conical sludge collection bucket; and finally, the sludge falls down under gravity and sludge resistance and falls into the conical sludge collection bucket. Because of the large impact force, even solid objects such as straws and stones with large sizes can be lifted by impact for subsequent collection and cleaning. Hence, the problem that the suction dredging method cannot clean up the solid objects such as straws and stones can be avoided. The device has broad application prospect.

Description

technical field [0001] The invention relates to a sewer dredging device, which belongs to the technical field of dredging. Background technique [0002] In urban sanitation work, it is necessary to regularly remove garbage, silt, etc. in urban sewers to ensure that the sewers are always smooth. However, the current sewer dredging project is mainly completed by manual on-site operations, which has high labor intensity, low efficiency, and poor quality. The cleaning effect is poor, and the suction dredging technology that has been adopted reduces the labor intensity of the operator to a certain extent and improves productivity, but it is still done by manual work to a considerable extent, and the energy consumption is large and the noise is large , which is not conducive to environmental protection. In addition, the suction desilting system requires high sealing and airtightness, many working ports are limited, and the adaptability is relatively poor. It is difficult to suctio...
