Description

Technical Field

The utility model is provided with a first motor, a rotating shaft, an auger and other components. When the feed hopper is feeding, by starting the first motor, the first motor drives the auger on the rotating shaft to rotate, and the auger can convey the incoming sewage sludge, thereby preventing the feed hopper from being clogged, and solving the problem that the feed hopper is easily clogged when the water conservancy project desilting device is used.

[0004] The problem with the above device is that when the silt and sewage mixture enters the box, the sewage flows downward due to the force of the sewage, and the sewage falls into the bottom of the box through the tiny holes on the surface of the filter screen for filtration, while the water contained in the silt is difficult to be quickly separated from the silt in a short period of time, resulting in a large amount of water content in the discharged silt, which increases the load of the silt transport carrier and requires the transport carrier to be loaded and unloaded multiple times, resulting in a high cost of dredging the silt.

A lifting component is provided at the bottom of the water collecting box 1. The lifting component is connected to the loading box 701. The lifting component can lift the loading box 701 in the vertical direction so that the sludge blocks formed after the sludge is squeezed can be taken out.

[0038] In some embodiments, as Figure 4 As shown, the water removal component 8 includes a top cover 801, a pressure plate 802 and a hydraulic rod 803. The top cover 801 is installed on the top of the charging box 701. The hydraulic rod 803 is installed on the top of the top cover 801. The output end of the hydraulic rod 803 passes through the bottom of the top cover 801. The output end of the hydraulic rod 803 is connected to the pressure plate 802.

The outer wall of the loading box 701 is connected with a first connecting block 703. The inner bottom of the water collecting tank 1 is fixedly installed with the fixing frame 10. The top of the fixing frame 10 is installed with the motor 11. The output end of the motor 11 is connected with the threaded rod 12. The threaded rod 12 is in rotational connection with the fixing frame 10. The threaded rod 12 penetrates through the first connecting block 703.

[0047] In some embodiments, as shown in Figure 1 , Figure 2 , the water collecting tank 1 is provided with a guide assembly on both sides of the loading box 701. The guide assembly can provide vertical guidance when the lifting assembly lifts the loading box 701.

[0048] Further, the guide assembly comprises a pair of guide rods 9. The two side outer walls of the loading box 701 are installed with a second connecting block 702. The second connecting block 702 is in sliding connection with the guide rod 9. The outer wall of the guide rod 9 is in sliding connection with the inner wall of the second connecting block 702. The bottom of the guide rod 9 is connected with the inner bottom of the water collecting tank 1.

[0049] The implementation principle of the dredging device for water conservancy projects is as follows:

[0050] When the water conservancy project is dredged, the device is installed and fixed on the suction dredger, and after the sludge pump is connected with the sludge pipe 705 through the external pipe body, the sludge in the river channel is sucked into the loading box 701 under the action of the sludge pump.

[0051] Firstly, part of the sewage in the sludge gradually penetrates downward through the small hole gaps on the surface of the filter screen 6, is collected from the multiple filter holes 5, flows into the inside of the rectangular frame 3, and is discharged into the water collecting tank 1 through the water discharge hole 704 arranged on the surface of the loading box 701.

[0052] When the external suction dredging work is stopped, after most of the water in the loading box 701 is lost, the hydraulic rod 803 arranged on the top of the top cover 801 is started, the output end of the hydraulic rod 803 is elongated to drive the pressing plate 802 to move towards the bottom of the loading box 701, the downward pressure on the sludge in the loading box 701 is slowly applied, the water in the sludge is rapidly penetrated downward into the rectangular frame 3, and is further guided and discharged into the water collecting tank 1, so that the water content in the sludge is greatly reduced, and the sludge is pressed into a rectangular sludge block.

[0053] After the external pump body is communicated with the water discharge pipe on the surface of the water collecting tank 1, the sewage in the water collecting tank 1 is guided to be discharged outside the suction dredger body. Then the motor 11 on the top of the fixing frame 10 is started, the output end of the motor 11 drives the threaded rod 12 to rotate, and due to the threaded connection between the threaded rod 12 and the first connecting block 703, the first connecting block 703 drives the loading box 701 to move upward, the bottom of the loading box 701 is separated from the top of the base 2, and the sludge block with less water content is taken out by the operator, is uniformly stacked and transported. Since the water content of the sludge is greatly reduced, the load of the sludge carrier is reduced, and the dredging cost is also reduced.

[0054] When the loading box 701 moves upward, the second connecting blocks 702 on both sides of the loading box 701 can synchronously slide on the outer surfaces of the two guide rods 9, and play a limiting role, so that the position is prevented from being deviated and colliding with the rectangular frame 3 when the box body is lowered subsequently.

[0055] The above are preferred embodiments of the utility model, and do not limit the protection scope of the utility model, so that: equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
