Description

Technical Field

[0001] The invention belongs to the technical field of desilting sludge treatment, and in particular relates to a desilting sludge treatment device for a reservoir in a water conservancy project. Background Art

[0002] As the service life of the reservoir increases, the accumulation of silt will seriously affect the normal operation and function of the reservoir. Therefore, the silt in the reservoir needs to be treated.

[0003] Reservoirs need to be desilted regularly to ensure water quality and effective storage capacity. Most of the current reservoir desilting is done by designing the reservoir desilting structure before the reservoir is built. However, this reservoir desilting structure alone is not enough to completely remove the silt. As time goes by, more and more silt will still accumulate. At this time, a silt removal device is needed to assist in desilting. However, the existing desilting method generally uses a pump to suck out the sludge, which can only be done near the dam. Since the sludge contains debris such as aquatic plants and a large amount of water, during the sludge discharge process, the debris may block the discharge pump, resulting in low dredging efficiency. If the silt cannot be removed, the reservoir can only be drained and then removed using equipment such as excavators, which not only wastes water resources, but also wastes a lot of manpower and financial resources.

[0004] In view of the above problems, the present invention proposes a sludge treatment device for desilting a reservoir in a water conservancy project. Summary of the invention

[0056] See also Figure 1-Figure 9 As shown, this embodiment is a method for using a sludge treatment device for desilting a reservoir in a water conservancy project: first, the hull 1 is driven to a place where sludge needs to be cleaned, the hydraulic telescopic rod 308 is retracted to move the crushing chamber 401 to the sludge to be cleaned, and the stepper motor 303 is turned on to drive the driving shaft 302 to rotate, and the crushing shaft 402 is driven to rotate by the driving belt 403.

[0058] When the sludge is transported to the inclined surface on the left side of the extrusion box 201, the pump 237 is turned on to suck the sludge to a suitable position. When the sludge is sucked, the reciprocating rod 230 is driven to rotate through the action of the driven belt 239. At this time, the reciprocating slider 232 slides in the reciprocating spiral groove 231 through the guide pendulum block, thereby driving the output pipe 236 to reciprocate along the reciprocating groove 229 until the sludge is cleaned up.
