And the water filtered by the filter bag 6 can be discharged into the river channel through the drainage tank 2 and the drainage pipe 3 in a backflow way, and the whole drainage process does not influence the surrounding environment.

In the process that the sludge is discharged into the filter bag 6, the addition of the flocculating agent can be carried out, the sedimentation of the sludge is accelerated, the rapid recovery is facilitated, the spiral blade 43 is started and driven to rotate through the motor 44, the spiral blade 43 rotates to convey the flocculating agent in the flocculating agent conveying pipe 42 and convey the flocculating agent into the vertical pipe 39, at the moment, the fourth electric push rod 40 is contracted, the feeding push head 41 is positioned at the lower end position of the vertical pipe 39, the flocculating agent is piled up at the upper end of the feeding push head 41, the third electric push rod 38 is in an extension state, the push block 51 is positioned at one end of the suction pipe 37, which is contacted with the sludge discharging interface 5, and seals the suction pipe 37, then the third electric push rod 38 is started and drives the push block 51 to pull back, the push block 51 extracts part of the sludge into the suction pipe 37, at the moment, the push block 51 is positioned at the rear end of the suction pipe 37, the fourth electric putter 40 starts and drives the feeding push head 41 to rise, push the flocculating agent into the suction tube 37 and mix with silt, afterwards the third electric putter 38 starts and stretches and drives the push block 51, the push block 51 pushes the silt of mixed flocculating agent into the silt discharging interface 5 and enters the filter bag 6 along with flowing silt, afterwards the feeding push head 41 moves down and resets, the addition of flocculating agent can be carried out again, simultaneously the belt driving motor inside the roller shaft mounting frame 12 plays and controls the belt to rotate, the belt drives a plurality of belt pulleys to rotate again, and then a plurality of rotating rollers 13 are controlled to rotate, a plurality of rotating rollers 13 continuously stir and disturb the inside of the filter bag 6, the mixing of the flocculating agent inside the filter bag 6 can be accelerated, the sedimentation efficiency of the silt is effectively improved, and the quick recovery of the silt is realized. The vertical pipe 39 will not enter the sludge in the process, the interior of the flocculant delivery pipe 42 will not be affected, and the flocculant can then be added as required, i.e. the process is repeated.

After the filter bag 6 finishes the collection amount of sludge (the collection amount is judged by staff), the upper third hydraulic telescopic rod 29 drives the pressing frame 30 to ascend and reset, the corresponding electric half ball valve 10 is closed, meanwhile, the first electric push rod 20 corresponding to the lower side of the sludge discharging port 5 drives the push plate 21 to move and pushes the plurality of U-shaped iron strips 19 to move, the U-shaped iron strips 19 at the edge are propped against one end of the placing groove 18, the U-shaped iron strips 19 correspond to the opening position of the placing groove 18, at the moment, the corresponding second electric push rod 23 ascends and drives the sucking disc 24 to ascend, the sucking disc 24 contacts with the lower side of the U-shaped iron strips 19 and adsorbs the U-shaped iron strips 19, the second electric push rod 23 continues to ascend until the U-shaped iron strips 19 stop after reaching a set station, the U-shaped iron strips 19 just correspond to the position of the sludge 7 of the filter bag 6, and then the corresponding two second hydraulic telescopic rods 25 respectively drive the two iron strip compression blocks 22 to move, so that the distance between the two iron strip compression blocks 22 is reduced and finally combined, the U-shaped iron strips 19 are extruded, and the U-shaped iron strips 19 are extruded and deformed, and the sludge is effectively sealed after the U-shaped iron strips 19 are extruded and deformed. Then the corresponding third electric push rod 38 is started to drive the push block 51 to pull back, the push block 51 sucks the sludge in the sealed sludge discharge port 5 and the sludge inlet 7 into the suction pipe 37, when the push block 51 pulls back, the feeding push head 41 is positioned at the upper end blocking position of the vertical pipe 39, then the corresponding two first hydraulic telescopic rods 16 shrink to drive the two extrusion blocks 17 to retract, the limiting effect on the flange ring 8 is relieved, the flange ring 8 is separated, and at the moment, because most of sludge is sucked into the suction pipe 37, the flange ring 8 is separated, and the situation that a large amount of sludge falls down and causes surrounding pollution does not exist. Then under the effect that a plurality of live rollers 13 rotated, the filter bag 6 of accumulation mud is carried on the corresponding board of placing 33, and two fourth hydraulic telescoping rods 36 of board 33 downside are placed and are started and shrink for place board 33 slope to one side rotation, and then make the filter bag 6 that is in board 33 upside of placing slide down, and filter bag 6 slide down is placed on the road surface, and the whole recovery transport of filter bag 6 and mud after effective convenience. At this time, the filter bags 6 at other stations can still collect the sludge, so that the sludge recovery continuity is effectively ensured, and after a plurality of filter bags 6 fall, the movable platform 1 moves forwards for a certain distance.

When changing empty filter bag 6, a plurality of filter bags 6 are piled up on hydraulic telescoping rod support frame 28, the staff is through taking out the filter bag 6 that is located the downside from hydraulic telescoping rod support frame 28, and push down and remove the flange ring 8 of this filter bag 6 and slide the embedding from between two spacing posts 15 in the U type heavy groove that the below corresponds, fix a position the station, the effective support flange ring 8 of sliding plate 27, and two corresponding first hydraulic telescoping rods 16 extension can drive two extrusion pieces 17 centre gripping fixed flange ring 8, will be the filter bag 6 that flange ring 8 corresponds and arrange silt interface 5 butt joint fixedly, afterwards the electronic half ball valve 10 that corresponds opens, can carry out the silt operation of filtering again.

When the sludge pumping assembly is applied, the sludge pumping device 49 sucks sludge, conveys the sludge into the butt joint pipe 11 through the conveying hose 50, conveys the sludge from the butt joint pipe 11 into the sludge shunt pipe 9, and distributes the sludge to the sludge discharge interfaces 5, so that the effect of sucking and dredging is achieved. Meanwhile, when the culvert at the river side needs to be cleaned, the moving vehicle 48 can be detached from the stabilizing seat 47 together with the sludge pumping device 49, and the moving vehicle 48 is arranged in the culvert and moves forward in the culvert, so that the sludge pumping device 49 can suck and clean sludge in the culvert, and cleaning diversity is realized.
