The mud water outlet 103 is connected to the part of the box body 1 located below the filter plate 3 and outside the enclosure 7; Figure 2 and Figure 1 As shown, when the extrusion plate 2 is located at the first position and the third position, the sealing plate 4 passes through and seals the first opening 301 and is inserted into the enclosure 7, that is, during the process of introducing mud into the box body 1 and squeezing the mud, the first opening 301 is sealed by the sealing plate 4.

[0023] The channel dredging mud treatment device provided in this scheme includes the following steps: like Figure 1 As shown, the sealing plate 4 seals the first opening 301 , the extrusion plate 2 is located at the third position, and then the mud is introduced into the area between the extrusion plate 2 and the filter plate 3 in the box body 1 through the mud inlet 101 .

[0024] like Figure 2 As shown, the power drives the extrusion plate 2 to move downward to the first position, and at the same time the sealing plate 4 moves downward in the enclosure 7 (if there is mud in the enclosure 7, the sealing plate 4 can push the mud downward during the downward movement of the enclosure 7 to prevent the mud from being blocked in the enclosure 7). During the downward movement of the extrusion plate 2, the mud is squeezed, and after the mud is dehydrated, the mud water flows downward through the filter holes on the filter plate 3 and is then discharged through the mud water outlet 103, and the mud blocks remain on the filter plate 3.

At this time, the sealing plate 4 is located above each push plate 6, and does not restrict the push plates 6 from rotating with the rotating shaft 5, and the first opening 301 is opened. Then the power drives the rotating shaft 5 to rotate, pushing the mud block through the first opening 301 into the enclosure 7, and then discharged through the mud block outlet 102.

[0026] In another embodiment, in the waterway dredging mud processing device, the mud block outlet 102 is arranged at the bottom of the box body 1, and the enclosure 7 is vertically arranged. The top and bottom of the enclosure 7 are respectively fixedly connected to the filter plate 3 and the bottom of the box body 1. When squeezing the silt and the sealing plate 4 moves downward in the enclosure 7, the mud blocks previously remaining in the enclosure 7 can be pushed downward to avoid the mud blocks being blocked in the enclosure 7.

[0027] In another embodiment, in the waterway dredging mud processing device, the vertical projection of the first opening 301 completely overlaps with the interior of the enclosure 7 and the vertical projection of the mud block outlet 102 .

[0028] In another embodiment, in the waterway dredging mud processing device, the lower part of the rotating shaft 5 is provided with a groove 501, at least one first guide groove and a push block 502, the groove 501 is recessed upward from the center of the bottom of the rotating shaft 5, each first guide groove is vertically arranged, and each first guide groove is connected to the groove 501, the push block 502 is arranged on the outer side wall of the rotating shaft 5, and the push block 502 drives the rotating shaft 5 between the fourth position and the fifth position (such as Figure 3 and Figure 4 The rotating shaft 5 is rotatably connected to the bottom of the box body 1 or the center of the filter plate 3, but the rotating shaft 5 can move up and down relative to the bottom of the box body 1 or the filter plate 3. For example, a circular through hole is provided on the bottom of the box body 1 or the filter plate 3, and the rotating shaft 5 passes through the through hole, thereby being rotatably connected to the bottom of the box body 1 or the filter plate 3, but can move up and down relative to the bottom of the box body 1 or the filter plate 3.

[0029] The channel dredging mud processing device also includes: The movable plate 8 is arranged in the box body 1 and is located below the filter plate 3 and above the push block 502 and the muddy water outlet 103. The rotating shaft 5 passes through the movable plate 8 and is rotatably connected with the movable plate 8, that is, when the rotating shaft 5 rotates, the movable plate 8 is not driven to rotate. A second opening is arranged on the movable plate 8, and the enclosure 7 passes through the second opening. A plurality of water outlet holes and a plurality of needle bodies 801 are arranged at intervals on the movable plate 8. The size of the water outlet hole is not less than the size of the filter hole on the filter plate 3, so that the muddy water passing through the filter hole can flow downward through the water outlet hole. Each needle body 801 is vertically arranged, and one needle body 801 is opposite to one filter hole; Figures 1 to 3 As shown, when the rotating shaft 5 is located at the fourth position, each needle body 801 is located below the filter plate 3 and is separated from the filter plate 3 by a certain distance; when the rotating shaft 5 is located at the fifth position, each needle body 801 passes through the filter hole corresponding thereto, so that the blockage in the filter hole can be pushed out by the needle body 801, and each needle body 801 is located below each push plate 6 and is separated by a certain distance, and the push plate 6 does not affect the blockage being pushed out by the needle body 801; The rotating rod 9 is vertically arranged, the upper part of the rotating rod 9 is inserted into the groove 501, and the lower part rotates under the drive of the power (device). At least one first guide block 901 is arranged on the rotating rod 9. The first guide blocks 901 correspond to the first guide grooves one by one. Each first guide block 901 is slidably arranged in the first guide groove corresponding to it. The first guide block 901 cooperates with the first guide groove to guide the rotating shaft 5 in the process of moving up and down relative to the rotating rod 9, and can also drive the rotating shaft 5 to rotate synchronously when the rotating rod 9 rotates; when the rotating shaft 5 moves up and down between the fourth position and the fifth position, each first guide block 901 is always located in the first guide groove corresponding to it.

[0030] During the process of squeezing the mud and discharging the mud blocks, the rotating shaft 5 is located at the fourth position, at which time the movable plate 8 and the needle body 801 thereon are located below the filter plate 3. When the mud blocks need to be discharged, the power drives the rotating rod 9 to rotate, which can drive the rotating shaft 5 and the push plate 6 to rotate. During the use of the filter plate 3, the filter holes on the filter plate 3 can be cleaned after each mud treatment. During cleaning, the power drives the push block 502 to move upward, thereby moving the rotating shaft 5 upward, and driving the push plate 6, the movable plate 8 and the needle body 801 thereon to move upward. When the rotating shaft 5 is located at the fifth position, each needle body 801 passes through the corresponding filter hole respectively, so that the blockage in the filter hole can be pushed out by the needle body 801. After the filter plate 3 is cleaned, the power drives the push block 502 to move downward, thereby moving the rotating shaft 5 downward, and driving the push plate 6, the movable plate 8 and the needle body 801 thereon to move downward until the rotating shaft 5 is located at the fourth position, and then the next round of mud treatment is carried out.

[0031] In another embodiment, in the waterway dredging mud processing device, the size of the water outlet hole is larger than the size of the filter hole on the filter plate 3, so that the muddy water passing through the filter hole can flow downward through the water outlet hole.

[0032] In another scheme, in the waterway dredging mud processing device, at least one second guide groove is provided on the side wall of the lower part of the box body 1, and each second guide groove is arranged in the vertical direction. At least one second guide block 802 is provided on the movable plate 8, and the second guide blocks 802 correspond to the second guide grooves one by one. Each second guide block 802 is slidably arranged in the corresponding second guide groove, and the second guide block 802 cooperates with the second guide groove to play a guiding role in the process of the movable plate 8 moving up and down. At the same time, because the enclosure 7 passes through the second opening on the movable plate 8, the enclosure 7 can also play a guiding role in the process of the movable plate 8 moving up and down.

[0033] In another embodiment, in the waterway dredging mud processing device, the bottom of the box body 1 is provided with an opening, the lower part of the rotating rod 9 is located below the rotating shaft 5 and the box body 1, and the waterway dredging mud processing device further includes: The watertight tube 10 is vertically arranged, the bottom of the watertight tube 10 is fixedly connected to the bottom of the box body 1, the vertical projection of the interior of the watertight tube 10 completely coincides with the vertical projection of the opening, the rotating shaft 5 passes through the opening and the interior of the watertight tube 10, the push block 502 is opposite to the interior of the watertight tube 10, and the height of the push block 502 is always higher than the height of the watertight tube 10, so that the watertight tube 10 will not affect the up and down movement of the push block 502; The driving device has a fixed end fixed to the lower part of the rotating rod 9, and the output end passes through the opening and the interior of the water-blocking tube 10, and is fixedly connected to the push block 502. The driving device can rotate with the rotating rod 9 and the rotating shaft 5, and when the rotating shaft 5 needs to move up and down, it can push the push block 502 and the rotating shaft 5 to move up and down.

[0034] The baffle 11 is fixed on the lower part of the rotating shaft 5 and is located between the moving plate 8 and the push block 502. The vertical projection of the water barrier 10 is located inside the vertical projection of the baffle 11. The vertical projection of the baffle 11 does not overlap with the vertical projection of the enclosure 7, that is, the enclosure 7 is located outside the baffle 11. Figure 5 As shown, the baffle 11 is indicated by a dotted line.

[0035] When the rotating shaft 5 is located at the fourth position, the lower part of the rotating shaft 5 is rotatably connected to the center of the bottom of the box body 1. Figure 4 As shown, when the rotating shaft 5 moves upward to the fifth position, the rotating shaft 5 is separated from the bottom of the box body 1, and there is a gap between the rotating rod 9 and the bottom of the box body 1. By providing the water-blocking cylinder 10, muddy water can be prevented from flowing out directly through the gap between the rotating rod 9 and the bottom of the box body 1. The water-blocking cylinder 10 cooperates with the baffle 11 to prevent sewage from flowing to the driving device that drives the push block 502 to move and the driving device that drives the rotating rod 9 to rotate.

[0036] In another embodiment, in the waterway dredging mud treatment device, the water-blocking cylinder 10 is cylindrical, and the baffle 11 is conical with a hollow interior and an open bottom.

[0037] In another embodiment, in the waterway dredging mud processing device, when the extrusion plate 2 is in the first position, the sealing plate 4 passes through the bottom of the enclosure 7 and extends to the bottom of the box body 1. The mud blocks in the enclosure 7 will inevitably get clogged or adhere to the inner wall of the enclosure 7. By setting the length of the sealing plate 4 to be long enough, the sealing plate 4 can push the mud blocks in the enclosure 7 downward during the downward movement of the enclosure 7, thereby preventing the mud blocks from getting stuck in the enclosure 7.

[0038] In another embodiment, in the waterway dredging mud processing device, when the rotating shaft 5 is located at the fourth position, each push plate 6 is in contact with the top of the filter plate 3, so that mud blocks are prevented from adhering to the filter plate 3.
