A return pipe 3 is connected between the bottom of the discharge pipe 41 and the right side of the sedimentation cylinder 42, and a water pump 31 is installed on the return pipe 3. A sand collecting cylinder 2 is placed on the top right side of the base 1, and the top of the sand collecting cylinder 2 is engaged with the sand discharge end of the hydrocyclone 101. The device also includes a drive motor 5, a rotating shaft 6, a housing 7, a turntable 8, a filter screen 9, and a pushing assembly. The housing 7 is fixedly connected to the right side of the feed pipe 4, and the housing 7 rotates in the middle. A rotating shaft 6 is connected to the housing 7. A turntable 8 is fixedly mounted on the right side of the rotating shaft 6. The turntable 8 is located inside the housing 7. Filter screens 9 are symmetrically attached to the turntable 8. The filter screens 9 can filter large particles of debris in the dredged waste. A drive motor 5 is installed on the lower left side of the housing 7. The output shaft of the drive motor 5 is connected to the left side of the rotating shaft 6 via a synchronous belt assembly. The drive motor 5 is used to drive the rotating shaft 6 to rotate 180 degrees. The rotating shaft 6 drives the turntable 8 to rotate, and the turntable 8 drives the filter screens 9 to rotate, so that the used filter screens 9 and unused filter screens 9 can be switched. A pusher assembly is provided on the housing 7. When the pusher assembly is in operation, it can push out the replaced filter screens 9.

[0027] Please see Figure 3As shown, the pushing assembly comprises a cylinder 10, a guide rod 11, a cross plate 12, a pushing rod 13, a guide cylinder 14, a lead screw 15, a receiving pipe 16 and a loading cylinder 161. The left front part of the shell 7 is fixedly penetrated by the receiving pipe 16. The bottom left part and the top right part of the receiving pipe 16 are both provided with openings. The receiving pipe 16 can collect the pushed filter screen 9. The right front part of the shell 7 is fixedly penetrated by the loading cylinder 161. The loading cylinder 161 can place the filter screen 9. The outer right side of the shell 7 is fixedly connected with the guide rod 11. The guide rod 11 is slidably sleeved with the cross plate 12. The left side of the cross plate 12 is fixedly connected with the middle part of the guide cylinder 14. The guide cylinder 14 is slidably connected with the pushing rod 13. The pushing rod 13 is located at the right side of the loading cylinder 161. When the pushing rod 13 moves to the left, the pushing rod 13 can push the new filter screen 9 to the rotating disc 8. The rear side of the cross plate 12 is rotatably penetrated by the lead screw 15. The lead screw 15 is threadedly connected with the rear right part of the pushing rod 13. The outer right side of the shell 7 is provided with the cylinder 10. The telescopic rod end of the cylinder 10 is fixedly connected with the rear side of the cross plate 12.

[0028] At the beginning, the outer side of the delivery pipe 4 is connected with the side throwing pipe of the dredger, and the inside of the sedimentation cylinder 42 is filled with a proper amount of supernatant, and the inside of the loading cylinder 161 is filled with a proper amount of filter screen 9. When the dredged spoil is discharged into the delivery pipe 4, the dredged spoil contacts the rear filter screen 9, and the rear filter screen 9 filters the large-particle impurities in the dredged spoil, so as to avoid the large-particle impurities from entering the hydrocyclone 101 to cause blockage and damage of the hydrocyclone 101, and further improve the operation reliability of the hydrocyclone 101. The dredged spoil filtered of the large-particle impurities continues to flow to the left through the rear filter screen 9. At this time, the water pump 31 is started, and the water pump 31 discharges the supernatant in the sedimentation cylinder 42 into the delivery pipe 4 through the backflow pipe 3. The supernatant is mixed with the dredged spoil to dilute the dredged spoil, so that the dredged spoil is more loose. The diluted dredged spoil continues to flow to the left and is discharged into the hydrocyclone 101. The hydrocyclone 101 is started, and the hydrocyclone 101 can complete the separation of the sand and mud in the dredged spoil, so that the sand is discharged into the sand collecting cylinder 2, and the mud and sand mixture is discharged into the discharge pipe 41. The mud and sand mixture in the discharge pipe 41 is discharged into the sedimentation cylinder 42 to produce supernatant. The supernatant continues to be pumped into the delivery pipe 4 for use. Thus, the separation of the sand and mud in the dredged spoil can be continuously completed. When the filter screen 9 needs to be replaced and cleaned after a long time of filtering impurities, the driving motor 5 is started. The driving motor 5 drives the rotation of the shaft 6 through the synchronous belt assembly transmission belt. The rotation of the shaft 6 drives the rotation of the turntable 8. The turntable 8 drives the rotation of the front and rear filter screens 9 by one hundred and eighty degrees. The used filter screen 9 is rotated to the front side, and the unused filter screen 9 is rotated to the rear side. Thus, the replacement of the filter screen 9 is completed. The driving motor 5 is turned off. Thus, the replacement of the filter screen 9 can be completed without interrupting the separation process, so as to improve the efficiency of the separation of the sand and mud. The new filter screen 9 continues to complete the separation of the sand and mud in the dredged spoil. Then the air cylinder 10 is started. The telescopic rod of the air cylinder 10 is shortened to drive the horizontal plate 12 to move to the left. The movement of the horizontal plate 12 to the left drives the guide cylinder 14 to move to the left. The movement of the guide cylinder 14 to the left drives the pushing rod 13 to move to the left. The movement of the pushing rod 13 to the left pushes the filter screen 9 in the loading cylinder 161 to move to the left. The leftmost filter screen 9 in the loading cylinder 161 pushes the used filter screen 9 on the turntable 8 to move to the left to separate. The used filter screen 9 moves to the left to the receiving pipe 16. The leftmost filter screen 9 in the loading cylinder 161 moves to the left and is clamped into the turntable 8. The air cylinder 10 is turned off. The pushing rod 13 stops pushing the filter screen 9 to move to the left. The operator can take out the used filter screen 9 in the receiving pipe 16 for cleaning.When the filter screen 9 in the charging cylinder 161 is used up, the air cylinder 10 is started to drive the horizontal plate 12 to move right to reset, the horizontal plate 12 drives the pushing rod 13 to move right to reset through the guide cylinder 14, the screw rod 15 is twisted to drive the pushing rod 13 to move right, so that the pushing rod 13 is completely in the guide cylinder 14, the screw rod 15 is stopped, and then a proper amount of filter screen 9 can be put into the charging cylinder 161, and then the screw rod 15 is twisted to drive the pushing rod 13 to move left to reset and contact with the filter screen 9 in the charging cylinder 161. When the dredged spoil is not discharged into the feeding pipe 4, the hydraulic cyclone 101 and the water pump 31 can be closed, the sand collecting cylinder 2 is separated from the hydraulic cyclone 101, and the sand is subjected to subsequent treatment.

[0029] Please refer to Figure 4 As shown in the figure, the cleaning assembly further comprises an L-shaped rod 17, a cleaning disc 18 and a spiral rod 19. The cleaning disc 18 is circumferentially rotatably connected to the left side of the receiving pipe 16. When the cleaning disc 18 rotates, the cleaning disc 18 can clean the impurities on the used filter screen 9. The spiral rod 19 is fixedly connected to the middle of the left side of the cleaning disc 18. The L-shaped rod 17 is fixedly connected to the front side of the left side of the horizontal plate 12. The rear end of the L-shaped rod 17 is in contact with the spiral groove of the spiral rod 19. When the L-shaped rod 17 moves, the L-shaped rod 17 can drive the spiral rod 19 to rotate.

[0030] Please refer to Figure 5 As shown in the figure, the material pushing assembly further comprises a pushing rod 20 and a spring 21. The pushing rod 20 is slidably connected to the bottom right side of the receiving pipe 16. When the pushing rod 20 moves upward, the pushing rod 20 can push the filter screen 9 after cleaning the impurities out of the receiving pipe 16. The spring 21 is connected between the lower part of the pushing rod 20 and the outer bottom of the receiving pipe 16.

[0031] When the used filter screen 9 is pushed into the receiving pipe 16, the used filter screen 9 is in contact with the cleaning disc 18, and at the same time, the horizontal plate 12 drives the L-shaped rod 17 to move left, the L-shaped rod 17 drives the spiral rod 19 to rotate, the spiral rod 19 drives the cleaning disc 18 to rotate, the cleaning disc 18 rotates to clean the impurities on the filter screen 9, and the cleaned impurities are discharged through the opening below the receiving pipe 16. When the horizontal plate 12 stops moving left, the horizontal plate 12 stops driving the L-shaped rod 17 to move left, the L-shaped rod 17 stops driving the spiral rod 19 to rotate, and the spiral rod 19 stops driving the cleaning disc 18 to rotate, so that the used filter screen 9 can be taken out of the receiving pipe 16. When the horizontal plate 12 moves right to reset, the horizontal plate 12 drives the L-shaped rod 17 to move right to reset. In this way, the operator does not need to manually clean the impurities on the filter screen 9, so that the impurities on the filter screen 9 can be more conveniently cleaned.

[0032] When the impurities on the filter screen 9 are cleaned, the ejector rod 20 is pushed to move upward, the spring 21 is compressed, the ejector rod 20 moves upward to push the filter screen 9 in the receiving tube 16 to move upward, the filter screen 9 moves upward to the outside of the receiving tube 16, and the filter screen 9 can be taken out, the ejector rod 20 is released, and the ejector rod 20 moves downward to reset due to the action of the spring 21. In this way, it is more convenient for the operator to take out the filter screen 9 in the receiving tube 16.

[0033] Please refer to Figure 6 As shown, the collecting box 22 is arranged at the bottom left of the receiving tube 16, the collecting box 22 corresponds to the opening at the lower part of the receiving tube 16, and the collecting box 22 can collect the impurities.

[0034] Please refer to Figure 7 As shown, the filter plate 23 is arranged at the inlet of the return pipe 3, and the filter plate 23 can filter the impurities in the supernatant.

[0035] When the cleaning disc 18 removes the impurities on the filter screen 9, the removed impurities fall into the collecting box 22 through the opening at the lower part of the receiving tube 16 and are collected, when the collecting box 22 contains a proper amount of impurities, the collecting box 22 can be taken off from the receiving tube 16 to pour out the impurities for treatment, and after the impurities are completely poured out, the collecting box 22 is clamped back to the receiving tube 16. In this way, the impurities can be prevented from falling to the surrounding environment to affect the environment, thereby ensuring a good environment.

[0036] When the water pump 31 starts to draw the supernatant in the sedimentation cylinder 42 into the conveying pipe 4 through the return pipe 3, the supernatant first contacts the filter plate 23, the filter plate 23 filters the impurities in the supernatant, and the supernatant after filtering the impurities is discharged into the conveying pipe 4 for use. In this way, the supernatant can be prevented from being mixed with impurities to cause the blockage of the return pipe 3, thereby ensuring the normal use of the return pipe 3.

[0037] Finally, it should be pointed out that: the above content is only used to help understand the technical scheme of the utility model, and cannot be understood as a limitation on the protection scope of the utility model; the non-essential improvements and adjustments made by the person skilled in the art according to the above content of the utility model all belong to the scope of the utility model claimed for protection.
