Background
Common sediments of the sludge urban pipeline are mainly distributed in urban pavement sewers, reservoirs, sewage pipes and other places, and contain a large amount of clay, gravels, organic sediments and other impurities, the sludge is easily attached to the inner wall of the pipeline to form a siltation layer, so that the water body of the sewer pipeline is prevented from flowing, and organic substances contained in the sludge can ferment and deteriorate under the action of the environment, breed bacteria and pollute the environment. Along with the urban development of China, the dredging work of underground water channels is more important, the sludge cleaned from the pipelines is quickly and efficiently treated, and the method has important significance for the construction work of urban environments. Although the method for directly sucking and transporting the sludge by using the pumping truck is simple and direct, the sludge contains a large amount of moisture, the transportation pressure and the cost are huge, and the sludge pollutes the environment, so that the transportation tightness of the sludge truck has high requirements, and the treatment cost is further increased.
Patent No. CN201921696381.6 proposes a box-shaped silt processing structure, which achieves the purpose of processing silt through stirring, elutriation and biological membrane filtration precipitation, but silt contains a large amount of sand and stone, if sand and stone are not separated, the whole processing mechanism is damaged, the silt processing efficiency is also influenced, and only natural precipitation is relied on, the efficiency is low, and the box-shaped silt processing structure is not suitable for processing a large amount of silt.
More specifically, the disadvantages in the prior art dredging apparatus are as follows.
1. The prior art dredging equipment separates sewage through the filter screen, however, silt falling from a high place can impact the filter screen, the impact force can cause undesired substances to pass through the filter screen, or the impact force can damage the filter screen.
2. In the dredging equipment in the prior art, the spiral extrusion column is often in an equal-diameter structure, however, the equal-diameter structure does not consider many factors such as: the size of the passing space of the medium and the size of the extrusion force of the medium, so the function is single.
3. In the dredging equipment in the prior art, the spiral extrusion column is driven by the motor, however, the motor is often additionally provided with a heightening plate or a supporting frame, so that the volume is increased, and the cost is increased.
4. In the desilting equipment in the prior art, the sludge is often directly discharged after being extruded, the on-off control and the regulation of the sludge discharge amount are lacked, the sludge cannot be on and off in time when a downstream storage chamber is filled in some special working conditions, and the downstream storage chamber is required to be stared to prevent the sludge from being too full through manual intervention. The use of conventional valves for sludge discharge requires technical difficulties to be overcome.
5. The prior art dredging device has the cleaning requirement, a separate cleaning channel is additionally arranged, however, if other functions such as a valve function and a manual driving device function are additionally added, the cost is increased and the volume is increased due to the superposition of too many functions.
6. In the dredging equipment in the prior art, the spiral extrusion column is driven by the motor, so that manual pipe connection in an emergency cannot be realized, and the motor drive or the manual drive device drive may exist in the prior art, but the size of the force arm for rotating the manual drive device is not considered in the drive.
