The lower side of the slag pan 442 is provided with a liquid leakage hole, a filter screen is arranged in the liquid leakage hole, the liquid leakage hole is connected with a liquid collecting barrel 443, the liquid collecting barrel 443 is connected with a liquid return pump 444, a liquid outlet of the liquid return pump 444 is communicated with the filter tank 413 through a municipal pipeline, the liquid leakage hole discharges filtrate which enters the slag pan 442 through carrying particles into the liquid collecting barrel 443, and the liquid return pump 444 conveys the filtrate in the liquid collecting barrel 443 into the filter tank 413 for filtering, so that the utilization efficiency of the filtrate is improved.
The flushing device 5, the dirt absorbing device 2 and the solid-liquid separation device 3 adopted in the implementation are all common structures in the related art, and will not be repeated here.
The implementation principle of the multifunctional dredging vehicle for municipal pipeline dredging provided by the embodiment of the application is as follows: the driving motor 433 drives the driving roller 431 to rotate, and the driving roller 431 rotates to drive the water seepage cloth 411 to circularly operate, so that the water seepage cloth 411 on the inlet side of the filter tank 413 continuously enters the filter tank 413 and then leaves the filter tank 413 from the outlet side of the filter tank 413. After the filtrate from the solid-liquid separator 3 enters the filter tank 413, the filtrate is filtered by the water seepage cloth 411 in the filter tank 413, the filtrate permeates into the lower part of the water seepage cloth 411, and particles are left in the filter tank 413, and as the water seepage cloth 411 is circulated into and out of the filter tank 413, the position of the water seepage cloth 411 contacted with the filtrate to be filtered in the filter tank 413 is continuously changed, so that the particles cannot be accumulated at the same position of the water seepage cloth 411, and the occurrence of the condition that the filtration failure or the filtration efficiency is reduced due to the blockage of the water seepage cloth 411 by the particles can be reduced. Therefore, the filtering holes of the water seepage cloth 411 in this embodiment can be made to be smaller than the filtering holes in the solid-liquid separator, so that fine particles in the filtrate are intercepted, the particles in the filtrate filtered by the water seepage cloth 411 are obviously reduced, and when the filtrate filtered by the water seepage cloth 411 is used for flushing municipal pipelines by the flushing device 5 again, the probability of the flushing device 5 being blocked is reduced, and the municipal pipeline dredging efficiency is improved. When the water permeable cloth 411 in the filter tank 413 leaves the filter tank 413, part of the particles are adsorbed on the water permeable cloth 411 and leave the filter tank 413 together with the water permeable cloth 411, so that the particles in the filter tank 413 are transported out, and the excessive particles accumulated in the filter tank 413 are prevented from reducing the filtering efficiency of the water permeable cloth 411. When the water seepage cloth 411 adsorbed with the particles passes through the brush, the brush scrapes off the particles on the water seepage cloth 411 and collects the particles on the slag receiving disc 442, the particles on the water seepage cloth 411 passing through the brush are greatly reduced, and the water seepage cloth can be used for filtering filtrate again for recycling.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the protection scope of the application.
