Description
Technical Field
The invention relates to the field of drainage equipment, in particular to a sewage filtering and concentrating device for a drainage pipeline jet dredging vehicle.
Background
The high-pressure water jet cleaning is suitable for cleaning small and medium-sized drainage pipelines and is more generally applied to foreign countries and places such as Beijing in China. The principle of the high-pressure jet cleaning of the drainage pipeline is that the high-pressure water is used for removing dirt such as oil stain and scale attached to the inner wall of the pipeline by utilizing the effects of erosion, cutting, cracking, stripping and the like, and the high-pressure jet cleaning device has the advantages of low cleaning cost, good cleaning quality, high cleaning speed, no pollution, wide application range and the like.
At present, jet dredging vehicles which take reclaimed water or tap water as a cleaning water source are more applied, and the reason is that firstly, because the jet dredging vehicles which take sewage as the cleaning water source after being treated have higher cost, only the burden of drainage pipeline operation units with great financial strength is caused, and the further popularization and application of the jet dredging vehicles are influenced; secondly, the later equipment maintenance cost is high, so that great economic pressure is caused to the operation unit of the jet dredging vehicle; thirdly, the ditch cleaning sludge formed after the sewage is treated is not further concentrated, so that the sewage can be conveyed to a ditch sludge treatment station after being statically precipitated to be treated, and the use efficiency of the sewage is influenced.
In recent years, many studies have been made at home and abroad on high-pressure water jet cleaning using sewage as a water source, and cleaning equipment has been developed in a direction of integration and automation. The dredging vehicle with more domestic applications can realize the purposes of dredging and dirt suction, but two operation modes can not be carried out simultaneously, and the improvement of the working efficiency is influenced. In recent years, a comprehensive dredging operation vehicle capable of simultaneously performing dirt absorption and dredging has been developed in Europe such as Kaiser company of Germany, but centrifugal filtration or multistage filtration is mostly adopted, the filtration precision is 0.5mm, the inner diameter of a nozzle is generally 0.5-1.5mm, and in practical application, the filtered water still contains fine silt, the abrasion to the nozzle is high, and the comprehensive dredging operation vehicle is not suitable for long-term use. In addition, the operation vehicle has no further concentration and dehydration step of sludge, and the sludge removal amount is insufficient. With the improvement of environmental awareness and the investment of modern construction and operation of drainage pipelines, the comprehensive dredging operation vehicle based on high-pressure water jet cleaning has more practical requirements on the operation mode that sewage, river water and the like are utilized to collect water sources nearby and are used as dredging media after being filtered, and the synchronous dredging and sewage suction can be realized.
