Technical Field

[0001] This utility model relates to a dredging device for water conservancy projects, specifically a dredging device for water conservancy projects, and belongs to the field of water conservancy dredging technology. Background Technology

[0002] Hydraulic engineering dredging devices are equipment and systems used to remove sediments or silt from the bottom of water bodies such as rivers, lakes, and reservoirs. Their main functions are to improve water quality, enhance waterway navigation capacity, restore water storage capacity, improve flood control capacity, and protect the normal operation of water conservancy facilities. These devices ensure the safety of water conservancy projects and the balance of the ecological environment by effectively removing sediments. However, many existing dredging devices cannot effectively separate water and silt after pumping out the silt. Some silt contains a large amount of lumpy polymers, which can easily clog pipes. This utility model can effectively separate silt mixtures and break up larger silt clumps, reducing the possibility of pipe blockage, which has certain practical applications. Utility Model Content

[0005] Preferably, a support plate is fixedly connected to one side of the top of the processing box, a screw pump is fixedly connected to the top side of the support plate, a feed pipe is fixedly connected to one side of the screw pump, and the other side of the screw pump is fixedly connected to the processing box.

[0006] Preferably, an upper partition is fixedly connected to the inner wall of the processing box, the upper partition is disposed on the bottom side of the cutting rod, a lower partition is fixedly connected to the inner wall of the processing box, and a filter cylinder is fixedly connected between the upper partition and the lower partition.

[0007] Preferably, a material collection funnel is fixedly connected to the middle of the lower partition, and the top of the material collection funnel abuts against the inner wall of the filter cylinder.

[0008] Preferably, a drain pipe is fixedly connected to one side of the processing box, and the drain pipe is flush with the top side of the lower partition.

[0009] Preferably, a U-shaped limiting plate is fixedly connected between the bottom center of the lower partition and the bottom inner wall of the processing box, and the end of the U-shaped limiting plate away from the No. 1 auger is connected and fixed to the processing box.

[0010] Preferably, a motor frame is fixedly connected to one side of the processing box. The motor frame is set at the same level as the U-shaped limiting plate. A discharge chute is provided on the bottom side of the motor frame. A second motor is fixedly connected to the side of the motor frame away from the U-shaped limiting plate. A second auger is fixedly connected to the second motor through the motor frame. The second auger is located inside the U-shaped limiting plate.

[0011] The beneficial effects of this utility model are as follows: By setting up a primary motor, this utility model can drive a rotating rod to rotate, which in turn drives a cutting rod to rotate. The cutting rod can effectively cut the sludge mixture entering the device, thereby breaking up the sludge clumps. This reduces the possibility of pipe blockage. The rotating rod can drive the guide limiting box to rotate via a fixed plate. The guide limiting box guides the sludge mixture falling from the upper partition to the filter cylinder, giving it a certain initial velocity so that it impacts the inner wall of the filter cylinder. Water will pass through the filter cylinder and enter the space between the processing box and the filter cylinder. The solid sludge slides down the gap between the guide limit box and the filter cylinder and finally falls onto the No. 1 auger along the filter cylinder. Since the sludge itself has a certain viscosity, the rotating rod can drive the No. 1 auger to rotate. The No. 1 auger is used to roll the sludge that falls onto the No. 1 auger downward and transport it to the U-shaped limit plate. The No. 2 motor can drive the No. 2 auger to rotate. The No. 2 auger is used to roll the sludge in the U-shaped limit plate to transport it to the motor frame and finally discharge it from the device through the discharge chute, thus realizing solid-liquid separation, which has certain practicality.
