Multifunctional desilting vehicle for desilting municipal pipelines

Abstract

The invention relates to a multifunctional dredging vehicle for dredging municipal pipelines, which comprises a vehicle body, and a flushing device, a dirt suction device, a solid-liquid separation device and a purification device are respectively mounted on the vehicle body; the purification device comprises a water seepage assembly, a guide assembly, driving assemblies and a slag scraping assembly, the water seepage assembly comprises water seepage cloth and a liquid receiving disc, the two ends of the water seepage cloth are connected with the driving assemblies respectively, and the driving assemblies drive the water seepage cloth to rotate; the upper portion of the water seepage cloth is tightly attached to the guide assembly and is connected with the guide assembly in a sliding mode, the guide assembly enables the upper portion of the water seepage cloth to form a filtering groove which is concave downwards, the liquid receiving disc is arranged below the filtering groove, and the slag scraping assembly is arranged below the lower portion of the water seepage cloth. The solid-liquid separation device has the effect of reducing the content of particulate matters in the filtrate passing through the solid-liquid separation device.

Description

technical field [0001] The invention relates to the field of special vehicles, in particular to a multifunctional dredging vehicle used for dredging municipal pipelines. Background technique [0002] The dredging work of municipal pipelines is to prevent the city from causing road water accumulation, urban waterlogging, and sewage overflow due to blockage of sewage municipal pipelines. Among them, the high-pressure water jet cleaning method is the leading equipment for industrial and civil municipal pipeline cleaning in the world, and the applicable proportion accounts for about 80-90%. This technology is also widely used in China. The silt and dirt attached to the pipe wall and in the municipal pipeline are washed away by high-pressure water jet cleaning, and then the silt and other dirt are pumped out from the wellhead to complete the desilting work of the municipal pipeline. The application of this technology generally requires the use of dredging trucks. The dredging tr...

Problems solved by technology

However, the water obtained by the solid-liquid separation device will also contain a lot of fine particles. These fine particles will easily cause the blockage of the flushing device, resulting in the interruption of the dredging work of municipal pipelines and reducing the efficiency of dredging.

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the water obtained through the solid-liquid separation device contains more fine particles, which is likely to cause blockage of the flushing device
