Embodiment 1

[0043] The urban pipe network sludge treatment method is characterized in that it comprises the following steps:

[0044] 1) Inspection well cleaning: clean up the inspection wells upstream and downstream of the dredging pipe section;

[0045] 2) Block upstream:

[0046] 3) Wear the traction rope: pass the traction rope through the upstream and downstream inspection wells and the pipelines to be dredged, and then connect it to the winch system on the ground;

[0047] 4) Pipeline survey: Connect the surveyor used for pipeline survey with the traction rope of the winch system, put the surveyor into the pipeline to be dredged through the traction rope, and conduct survey on the pipeline to be dredged. After the survey is completed, pass The traction rope lifts the surveyor to the ground;

[0048] 5) Silt cleaning: first connect the digging device with the traction rope of the hoisting system, put the digging device into the pipeline to be dredged through the traction rope, and ...

Embodiment 2

[0051] like Figure 1 to Figure 4 As shown, it is improved on the basis of Example 1. In the step 1), the inspection wells upstream and downstream of the dredging pipe section are cleaned with auxiliary work vehicles, and different types of silts are used according to the type and degree of consolidation in the inspection wells. Catch and dig. Start the hydraulic grab 1, the hydraulic grab 1 grabs the water-containing sediment, and the muddy water flows out from the lower tank of the hydraulic grab 1 and the leakage holes on both sides to realize the separation of the muddy water. Turn to and lift to ground again, pour into mud storage bin 2. When hardened sediment is encountered, the grab arm rotates to cut and stir the sediment, and then grabs and lifts it; when the on-board sludge storage tank is full, the storage tank is lifted by the hydraulic bottom shaft, and the sludge is poured into the sludge transport vehicle .

[0052] In described step 2), use air bag 8 to bloc...

Embodiment 3

[0059] like Figure 4 As shown, it is improved on the basis of Example 1 or Example 2. After the sludge cleaning in the step 5) is completed, the sludge treatment vehicle is used to complete the sludge reduction treatment and water recovery of the cleaned sludge, and the sludge treatment The car includes a coarse grid machine 17, a cyclone 18, a settling chamber 19, a belt filter press 20 and a circulating water collection tank 21. The mud in the pipeline enters the coarse grid machine 17 through a suction pump, and then passes through the cyclone. 18 screening, settling chamber 19 flocculation, belt filter press 20 filter press dehydration process, complete sludge reduction treatment and water reuse.

[0060] Then the dried silt is transported out with the silt transport unit, and the silt transport unit mainly consists of a silt transport flatbed truck and a trailer head 6. The box body of the sludge transport flatbed truck is a funnel-type sewage storage box 7. In order to...

Abstract

The invention discloses a method and a system for treating sludge in an urban pipe network. The method comprises the following steps: inspection well cleaning→blocking upstream→passing a traction rope→pipeline survey→silt cleaning, which also includes installing a guide device, sludge reduction treatment, drying Silt removal process, a sludge treatment system for urban pipe network, including hoisting system, shuttle cable passer, full-view pipeline surveyor, digging basket and sludge dredging vehicle, and may also include sludge drying treatment vehicle, The optimized combination of system equipment has a wide range of applications, is safe and effective, and does not require personnel to enter a closed and harsh environment for operation. It meets the product requirements of ergonomics and realizes systematization, unitization, and high integration. The cleaning effect is better and meets the needs of modern cities. Ecological environment protection requirements.

Description

technical field [0001] The invention relates to the technical field of dredging equipment, in particular to a method and system for treating sludge in an urban pipe network. Background technique [0002] At present, one of the main reasons for the black and smelly rivers is the random discharge of rainwater and sewage along with the pipelines. The current construction and maintenance of various drainage outlets, drainage pipelines and inspection wells are improper, resulting in a large amount of groundwater and other external water passing through the drainage outlets, pipelines and inspection wells. All kinds of structural defects in the drainage pipes, combined with the mixed connection of rain and sewage pipes and the direct discharge of sewage, weakened the due effect of the source control and interception measures, and became the bottleneck restricting the improvement of black and odorous water bodies; at the same time, it also caused sewage treatment. The influent conc...
