Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering, and in particular to a sludge cleaning device for river channel management in municipal engineering. Background Art

[0002] Urban municipal infrastructure is an important guarantee for building urban material and spiritual civilization. Urban municipal infrastructure is the foundation of urban development and a key facility to continuously ensure the sustainable development of the city. It is mainly composed of various engineering systems such as transportation, water supply, drainage, gas, sanitation, power supply, communication, disaster prevention, and landscaping. Due to the narrow width of municipal rivers and the slow flow of river water, silt will accumulate on the bottom of municipal rivers after a period of time. If dredging is not carried out for a long time, it will cause river blockage, rising river water, and deterioration of water quality. Therefore, it is necessary to regularly dredge municipal rivers. The structure of traditional river silt treatment devices is relatively simple and cannot filter out water from the silt or perform subsequent treatment on the silt.

[0003] Prior art: Chinese patent CN119308369B discloses a sludge cleaning device for river management in municipal engineering, including a hull, a mechanical arm is installed on the top front side of the hull, a bucket is installed on the end of the mechanical arm away from the hull, a uniformly distributed controller is arranged on the top of the hull, tracks are installed on the left and right sides of the bottom of the hull, a centrifuge and a placement box are installed inside the hull, a connecting pipe is fixedly connected to the opposite side of the centrifuge and the placement box, a drain pipe 1 is fixedly connected to one side of the bottom of the centrifuge, and the outer wall of the drain pipe 1 is fixedly connected to the inside of the hull. The buoyancy of the floating block drives the connecting plate to rise, and the rotating plate can drive the connecting plate to move so that the bevel gear 1 and the bevel gear 2 are meshed. Under the coordinated work of bevel gear 1, bevel gear 2 and the belt, the tracks and propellers are rotated synchronously to enhance the maneuverability and operating efficiency of the device in deep water; The prior art uses a centrifuge for dehydration, but does not mention the control of the moisture content of the sludge after dehydration. The sludge separated by the centrifuge may still contain a high moisture content, resulting in difficulties in subsequent transportation and resource utilization. In addition, the storage box capacity is limited, and frequent shutdowns for cleaning are required, which affects the actual use effect. Summary of the invention

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are: 1. In the sludge cleaning operation, the dual-axis motor carried by the rotating component drives the active wheel with its strong power, and then drives the driven wheel to rotate at high speed. The second rotating shaft connected to the driven wheel can cause the fixed reamer to rotate at a very high speed to efficiently crush the river sludge. At the same time, the fan blades rotate at high speed in the base cavity, and cooperate with the air inlet at the top of the base and the air outlet on the right side to accelerate the discharge of water in the base, and further dry the compacted sludge, which greatly improves the sludge cleaning efficiency and significantly shortens the cleaning cycle, so that the treated sludge can be directly used for landfill or resource utilization.

[0015] 2. The centrifugal assembly makes full use of the principle of centrifugal force by means of the high-speed rotation of the centrifugal cylinder to carry out efficient solid-liquid separation of the sucked sludge. Under the action of centrifugal force, the water in the sludge is quickly thrown out through the dense sieve holes outside the centrifugal cylinder and discharged smoothly through the drainage pipes connected on the left and right sides of the protective cylinder, thereby achieving preliminary dehydration of the sludge. The compaction assembly makes it possible for the third bevel gear meshing with the second bevel gear to rotate when the second bevel gear rotates, thereby driving the rotating rod and the fixed column to move, and finally making the fixed frame and the bottom pressure plate move up and down, thereby compacting the sludge discharged from the bottom discharge port of the centrifugal cylinder, which not only greatly reduces the volume of the sludge, facilitating subsequent transportation, but also further reduces its water content, significantly improving the cleaning quality.
