Description

Technical Field

[0001] This invention relates to the field of waterway dredging technology, specifically to a waterway dredging mud solidification device and method. Background Technology

[0002] The construction and maintenance of ports (increasing port throughput), ensuring the flood discharge capacity of rivers, guaranteeing unobstructed navigation, and enhancing the flood storage capacity of lakes all require dredging of rivers and lakes, generating a large amount of dredged sludge. Simultaneously, with the acceleration of industrialization and urbanization, water pollution problems are becoming increasingly serious, and dredging bottom sediment is necessary to remove the internal sources of water pollution. Therefore, ecological dredging is required when restoring and treating polluted rivers and lakes, which also generates a large amount of dredged sludge.

[0003] Most existing mud solidification processes typically involve first pressing the mud through filter plates or screens, then adding a solidifying agent and mixing it with a stirring rod to solidify it. However, in actual use, when pressing mud through filter plates or screens, some mud enters the filter pores, reducing the subsequent filtration performance of the filter plates or screens. Furthermore, the problem of the mud itself being heavy, having poor fluidity, and being prone to stratification is often overlooked during the mixing process. Adding solidifying additives during mixing makes it difficult to achieve a good mixing effect, resulting in the mud often exhibiting prolonged solidification time and a tendency to disintegrate during the solidification process. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a device and method for solidifying dredging mud in waterways.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for solidifying dredging mud in a waterway includes a mixing cylinder, wherein a stirring structure is provided inside the mixing cylinder, and further includes:

[0007] A separating cylinder is disposed inside a mixing cylinder. A first electric push rod is disposed between the separating cylinder and the inner wall of the mixing cylinder. An inlet and an outlet are respectively disposed at the top and bottom of the separating cylinder. A bottom plate is rotatably disposed at the outlet. A second electric push rod is movably disposed between the bottom plate and the separating cylinder.

[0008] A cylinder unblocking assembly is disposed inside a mixing cylinder, and both ends of the cylinder unblocking assembly are respectively connected to the mixing cylinder and the separating cylinder;

[0009] And a powder mixing component, which is located on the lower side of the separation cylinder and is used to mix lime powder and filter-pressed mud blocks.

[0010] Preferably, the separating cylinder includes a water receiving shell fixedly connected to the first electric push rod, a filter screen cylinder rotatably connected to the inside of the water receiving shell, a discharge mechanism disposed in the filter screen cylinder, a first motor fixedly disposed in the water receiving shell, a drive gear disposed on the output shaft of the first motor, and a driven gear fixedly connected to the top of the filter screen cylinder. The inlet and outlet are respectively disposed at the top and bottom of the filter screen cylinder, and a wire mesh frame is disposed on the outlet.

[0011] Preferably, the discharge mechanism includes a second motor fixed to the top of the filter cylinder, a conveying shaft connected to the output shaft of the second motor and rotatably connected inside the filter cylinder, and a spiral conveying blade fixed to the conveying shaft. The spiral conveying blade moves against the inner wall of the filter cylinder, and the diameter of the filter cylinder gradually decreases from top to bottom.

[0012] Preferably, the cylinder unblocking assembly includes a fixing rod fixed to the inner wall of the mixing cylinder and slidably connected to the water receiving shell. The fixing rod is located on the side of the mixing cylinder away from the first electric push rod. An abutment plate is fixed to the end of the fixing rod away from the mixing cylinder, and the abutment plate moves against the filter cylinder.

[0013] Preferably, the cylinder unblocking assembly further includes a fixed pipe fixed to the outside of the fixed rod, a piston slidably connected inside the fixed pipe, the piston dividing the fixed pipe into a left cavity and a right cavity, an air inlet valve being provided in both the left and right cavities, a connecting pipe being provided between the piston and the outer wall of the water receiving shell, the connecting pipe being slidably connected to the fixed rod and the fixed pipe, an exhaust telescopic pipe being provided between the left cavity of the fixed pipe and the abutment plate, a first air outlet valve being provided inside the exhaust telescopic pipe, a cavity communicating with the exhaust telescopic pipe being opened on the abutment plate, and several air jets communicating with the cavity being opened on the side of the abutment plate near the filter cylinder.

[0014] Preferably, the powder mixing assembly includes an annular powder box fixed at the bottom of the separation cylinder, the inner sidewall of the annular powder box having several through holes, and an exhaust pipe communicating between the right cavity of the fixed tube and the annular powder box, with a second exhaust valve installed in the exhaust pipe.

[0015] Preferably, a connecting rod is fixedly provided on the inner side wall of the mixing cylinder, and a swing rod is rotatably connected to the connecting rod. The end of the swing rod away from the connecting rod is rotatably connected to a lifting rod through a pin. The lifting rod is slidably connected to the annular powder box, and a movable plate that moves inside the annular powder box is connected to the bottom of the lifting rod.

[0016] Preferably, the annular powder box is provided with a plurality of positioning rods that slide with the movable plate in a circular shape. The positioning rods are provided with spiral track grooves. The upper and lower sides of the movable plate are rotatably connected to collars through bearings. The collars are provided with a plurality of stirring blades evenly arranged in a circular shape. The inner sidewall of the collar is provided with guide blocks that slide with the spiral track grooves.

[0017] Preferably, a protective tube is fixed to the outside of the collar and sleeved on the outside of the positioning rod to cover the spiral track groove.

[0018] This invention also discloses a method for solidifying dredging mud, which involves processing the dredging mud using the aforementioned solidification device, and includes the following steps:

[0019] S1: Connect the slurry discharge pipe to the feed inlet at the top of the separator, and then discharge the slurry into the separator;

[0020] S2: Control the operation of the first motor. When the first motor is running, it drives the drive gear to mesh with the driven gear on the filter screen cylinder, thereby causing the filter screen cylinder to drive the mud to rotate centrifugally, so that the mud can undergo preliminary mud-water separation.

[0021] S3: Then control the second electric push rod to retract so that it drives the bottom plate to flip. The bottom of the filter cylinder is then open. Control the second motor to run. The second motor drives the spiral conveying blades on the outside of the conveying shaft to rotate. The spiral conveying blades press down and convey the mud blocks that have undergone preliminary mud-water separation inside the filter cylinder. As the inner diameter of the filter cylinder gradually decreases, the water in the mud blocks is further squeezed out and enters the water receiving shell. The mud blocks removed from the filter cylinder are cut into several strips by the wire mesh frame. Then the cut mud blocks fall to the bottom of the mixing cylinder.

[0022] S4: Then control the first electric push rod to push the separation cylinder to move back and forth in the mixing cylinder, control the cylinder unblocking component to work, unblock the filter holes of the filter screen cylinder, and remove the mud in the filter holes;

[0023] S5: When the separator moves back and forth, it drives the annular powder box to move, causing the curing agent powder in the annular powder box to shake and loosen. When the cylinder unblocking component works, it drives the powder mixing component to work, so that the curing agent powder in the annular powder box is fully mixed with the mud blocks removed from the filter cylinder.

[0024] As can be seen from the above technical solutions, the present invention has the following beneficial effects:

[0025] 1. In this invention, the filter screen cylinder is cleared by the cylinder clearing component to ensure the separation efficiency and effect of the subsequent filter screen cylinder on mud and water. When the cylinder clearing component is working, it drives the powder mixing component to work, causing the annular powder box to shake, avoiding the lime powder in the annular powder box from clumping and affecting the mixing effect with the mud block after pressing, thereby ensuring the slurry solidification efficiency and solidification effect.

[0026] 2. In this invention, when the first electric push rod drives the separating cylinder to move left and right inside the mixing cylinder, the filter cylinder inside the separating cylinder intermittently abuts against the abutting plate at the end of the fixed rod. When the filter cylinder abuts, it vibrates under force, which loosens the mud clogging the inner wall of the filter cylinder mesh. When the separating cylinder moves left and right, it drives the piston to move inside the fixed pipe through the connecting pipe, which allows the air in the fixed pipe to be discharged to the abutting plate through the exhaust telescopic pipe and sprayed onto the filter cylinder through the air jet port of the abutting plate. This quickly removes the mud clogging the filter cylinder mesh, ensuring the subsequent mud-water separation effect and separation efficiency of the filter cylinder.

[0027] 3. In this invention, by setting a steel wire frame at the discharge port, the mud blocks removed from the discharge port are divided into several strip-shaped mud blocks. When the first electric push rod drives the separation cylinder to move left and right in the mixing cylinder, the several strip-shaped mud blocks removed from the discharge port swing, thereby increasing the distance between the strip-shaped mud blocks. This allows the lime powder sprayed from the annular powder box to fully adhere to the strip-shaped mud blocks, increasing the contact area between the lime powder and the filtered mud blocks. This, in turn, allows the lime powder and mud blocks to mix quickly and evenly, reducing the slurry solidification time and ensuring the slurry solidification effect.

[0028] 4. In this invention, when the first electric push rod drives the separating cylinder to move left and right in the mixing cylinder, the lifting rod drives the movable plate to move up and down in the annular powder box to stir the lime powder. When the movable plate moves up and down, it drives the collar to move relative to the positioning rod. The guide block cooperates with the spiral track groove, so that when the collar moves up and down with the movable plate, it drives the stirring blade to further stir the lime powder in the annular powder box, avoiding the lime powder from clumping and ensuring that the lime powder and mud are fully mixed.

[0029] 5. In this invention, the piston slides back and forth frequently inside the fixed tube, causing the inner wall of the fixed tube to heat up. The fixed tube heats the air drawn into it, and the heated air is discharged into the annular powder box through the exhaust pipe, keeping the lime powder in the annular powder box dry, effectively preventing it from clumping, and further ensuring that the lime powder and mud are mixed evenly.

Detailed Implementation

[0043] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0044] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0045] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 9As shown, this embodiment proposes a channel dredging slurry solidification device, including a mixing cylinder 1, a stirring structure inside the mixing cylinder 1, and further including: a separation cylinder 2, a cylinder dredging component, and a powder mixing component; the separation cylinder 2 is disposed inside the mixing cylinder 1, a first electric push rod 3 is disposed between the separation cylinder 2 and the inner wall of the mixing cylinder 1, the top and bottom of the separation cylinder 2 are respectively provided with a feed inlet 201 and a discharge outlet 202, a bottom plate 2021 is rotatably disposed at the discharge outlet 202, and a second electric push rod 4 is movably disposed between the bottom plate 2021 and the separation cylinder 2; the cylinder dredging component is disposed inside the mixing cylinder 1, and both ends of the cylinder dredging component are connected to the mixing cylinder 1 and the separation cylinder 2 respectively; the powder mixing component is disposed on the lower side of the separation cylinder 2 and is used to mix lime powder and filter-pressed mud blocks.

[0046] Specifically, the slurry discharge pipe is connected to the feed inlet 201 at the top of the separation cylinder 2, and then the slurry is discharged into the separation cylinder 2. The separation cylinder 2 is controlled to rotate, which in turn causes the filter cylinder 6 to drive the slurry to rotate centrifugally, so that the slurry undergoes preliminary mud-water separation. Then, the second electric push rod 4 is controlled to retract, causing the bottom plate 2021 to flip. At this time, the bottom of the filter cylinder 6 is opened, and the mud blocks that have undergone preliminary mud-water separation in the filter cylinder 6 fall to the bottom of the mixing cylinder 1. Then, the first electric push rod 3 is controlled to push the separation cylinder 2 to move back and forth in the mixing cylinder 1, and the cylinder unblocking component is controlled to work to unblock the filter holes of the filter cylinder 6, remove the mud blocks in the filter holes, and ensure the separation efficiency and effect of the subsequent mud-water separation by the filter cylinder 6. When the cylinder unblocking component is working, it drives the powder mixing component to work, effectively avoiding the lime powder clumping from affecting the mixing effect with the mud blocks after pressing, thereby ensuring the slurry solidification efficiency and solidification effect.

[0047] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, in a preferred embodiment, based on the above method, the separating cylinder 2 further includes a water receiving shell 5 fixedly connected to the first electric push rod 3, a filter cylinder 6 rotatably connected to the inside of the water receiving shell 5, a discharge mechanism disposed in the filter cylinder 6, a first motor 7 fixedly disposed in the water receiving shell 5, a drive gear 701 disposed on the output shaft of the first motor 7, and a driven gear 702 fixedly connected to the top of the filter cylinder 6. The inlet 201 and the outlet 202 are respectively disposed at the top and bottom of the filter cylinder 6, and a wire mesh frame 2022 is disposed on the outlet 202.

[0048] Furthermore, the discharge mechanism includes a second motor 8 fixed at the top of the filter cylinder 6, a conveying shaft 801 connected to the output shaft of the second motor 8 and rotatably connected inside the filter cylinder 6, and a spiral conveying blade 802 fixed on the conveying shaft 801. The spiral conveying blade 802 moves against the inner wall of the filter cylinder 6, and the diameter of the filter cylinder 6 gradually decreases from top to bottom.

[0049] Specifically, after the slurry is discharged into the separation cylinder 2, the first motor 7 is controlled to operate. When the first motor 7 operates, it drives the drive gear 701 to mesh with the driven gear 702 on the filter cylinder 6, thereby causing the filter cylinder 6 to rotate the slurry centrifugally, thus performing preliminary mud-water separation. The separated water enters the water receiving shell 5. Then, the second electric push rod 4 is controlled to retract, causing it to rotate the bottom plate 2021. At this time, the bottom of the filter cylinder 6 is opened, and the second motor 8 is controlled to operate. The second motor 8 drives the spiral conveying blades 802 on the outside of the conveying shaft 801 to rotate, causing the spiral conveying blades 802 to press down and convey the mud blocks that have undergone preliminary mud-water separation inside the filter cylinder 6. As the inner diameter of the filter cylinder 6 gradually decreases, the water inside the mud block is further squeezed out and enters the water receiving shell 5. The mud block removed from the filter cylinder 6 is cut into several strips by the wire mesh frame 2022. Then, the cut mud block falls to the bottom of the mixing cylinder 1. When the first electric push rod 3 drives the separation cylinder 2 to move left and right in the mixing cylinder 1, the several strip mud blocks removed from the discharge port 202 swing, thereby increasing the distance between the strip mud blocks, so that the lime powder can fully adhere to the strip mud blocks, increasing the contact area between the lime powder and the mud blocks after pressing, thereby making the lime powder and mud blocks mix quickly and evenly, reducing the mud solidification time and ensuring the mud solidification effect.

[0050] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, in a preferred embodiment, based on the above method, the cylinder unblocking component further includes a fixing rod 9 fixedly disposed on the inner wall of the mixing cylinder 1 and slidably connected to the water receiving shell 5. The fixing rod 9 is disposed on the side of the mixing cylinder 1 away from the first electric push rod 3. An abutment plate 901 is fixedly disposed at the end of the fixing rod 9 away from the mixing cylinder 1, and the abutment plate 901 abuts against the filter cylinder 6.

[0051] Furthermore, the cylinder unblocking assembly also includes a fixed pipe 10 fixed to the outside of the fixed rod 9. A piston 1001 is slidably connected inside the fixed pipe 10. The piston 1001 divides the fixed pipe 10 into a left cavity and a right cavity. An air inlet valve is provided in both the left cavity and the right cavity. A connecting pipe 1002 is provided between the piston 1001 and the outer wall of the water receiving shell 5. The connecting pipe 1002 is slidably connected to the fixed rod 9 and the fixed pipe 10. An exhaust telescopic pipe 11 is provided between the left cavity of the fixed pipe 10 and the abutment plate 901. A first air outlet valve is provided inside the exhaust telescopic pipe 11. A cavity communicating with the exhaust telescopic pipe 11 is opened on the abutment plate 901. Several air jets 9011 communicating with the cavity are opened on the side of the abutment plate 901 near the filter cylinder 6.

[0052] Specifically, by controlling the first electric push rod 3, the separating cylinder 2 is pushed to move back and forth in the mixing cylinder 1, so that the filter cylinder 6 in the separating cylinder 2 intermittently abuts against the abutting plate 901 at the end of the fixed rod 9. When the filter cylinder 6 abuts, it vibrates under force, which loosens the mud blockage on the inner wall of the filter cylinder 6 mesh. At the same time, the filter cylinder 6 can be driven to rotate during this period, so that the abutting plate 901 can abut against and collide with different positions of the filter cylinder 6, ensuring that the filter cylinder 6 is subjected to uniform force and avoiding the fact that it is always subjected to force in the same position, which will affect its service life. When the separating cylinder 2 moves left and right, the piston 1001 moves in the fixed pipe 10 through the connecting pipe 1002, so that the air in the fixed pipe 10 is discharged to the abutting plate 901 through the exhaust telescopic pipe 11, and sprayed onto the filter cylinder 6 through the air jet 9011 of the abutting plate 901, so that the mud blockage at the mesh of the filter cylinder 6 is quickly removed, ensuring the subsequent mud-water separation effect and separation efficiency of the filter cylinder 6.

[0053] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, based on the above method, the powder mixing assembly further includes an annular powder box 12 fixed at the bottom of the separation cylinder 2. The inner side wall of the annular powder box 12 is provided with several through holes 121. An exhaust pipe 122 is connected between the right cavity of the fixed pipe 10 and the annular powder box 12. A second exhaust valve is provided in the exhaust pipe 122.

[0054] Furthermore, a connecting rod 13 is fixedly provided on the inner wall of the mixing cylinder 1, and a swing rod 131 is rotatably connected to the connecting rod 13. The end of the swing rod 131 away from the connecting rod 13 is rotatably connected to a lifting rod 132 through a pin. The lifting rod 132 is slidably connected to the annular powder box 12, and the bottom of the lifting rod 132 is connected to a movable plate 133 that moves inside the annular powder box 12.

[0055] Specifically, when the first electric push rod 3 pushes the separating cylinder 2 to move back and forth in the mixing cylinder 1, the annular powder box 12 moves synchronously, causing the curing agent powder in the annular powder box 12 to shake and loosen. During this period, the swing rod 131, in conjunction with the lifting rod 132, drives the movable plate 133 to move in the annular powder box 12, so that the movable plate 133 further agitates the curing agent powder in the annular powder box 12, preventing the curing agent powder from clumping. Furthermore, the piston 1001 slides back and forth frequently in the fixed tube 10, causing the inner wall of the fixed tube 10 to heat up. The fixed tube 10 heats the air drawn into it, and the heated air is discharged into the annular powder box 12 through the exhaust pipe 122, keeping the curing agent powder in the annular powder box 12 dry and effectively preventing it from clumping, further ensuring that the lime powder and mud are mixed evenly.

[0056] Reference Figure 5 , Figure 7 , Figure 11 and Figure 12 As shown, in a preferred embodiment, based on the above method, further, a plurality of positioning rods 14 are fixedly arranged in a circular shape inside the annular powder box 12, which slide with the movable plate 133. The positioning rods 14 are provided with spiral track grooves 141. The upper and lower sides of the movable plate 133 are rotatably connected to collars 15 through bearings. A plurality of stirring blades 151 are evenly arranged in a circular shape on the collars 15. The inner sidewall of the collars 15 is fixedly provided with guide blocks 152 that slide with the spiral track grooves 141.

[0057] Furthermore, a protective tube 16 is fixedly provided on the outside of the collar 15 and sleeved on the outside of the positioning rod 14 to cover the spiral track groove 141.

[0058] Specifically, when the powder mixing component is in motion, the lifting rod 132 drives the movable plate 133 to move up and down reciprocally within the annular powder box 12, thereby agitating the lime powder. When the movable plate 133 moves up and down, it drives the collar 15 to move relative to the positioning rod 14. The guide block 152 cooperates with the spiral track groove 141, so that when the collar 15 moves up and down with the movable plate 133, it drives the stirring blade 151 to further agitate the lime powder in the annular powder box 12, preventing the lime powder from clumping and ensuring that the lime powder and mud are fully mixed. The protective tube 16 is sleeved on the outside of the positioning rod 14 to prevent the powder from entering the spiral track groove 141 and affecting the normal sliding of the guide block 152, thereby ensuring the stable stirring operation of the stirring blade 151.

[0059] This invention also discloses a method for solidifying dredging mud, which involves processing the dredging mud using the aforementioned solidification device, and includes the following steps:

[0060] S1: Connect the slurry discharge pipe to the feed inlet 201 at the top of the separator 2, and then discharge the slurry into the separator 2;

[0061] S2: Control the operation of the first motor 7. When the first motor 7 is running, it drives the drive gear 701 to mesh with the driven gear 702 on the filter cylinder 6, thereby causing the filter cylinder 6 to drive the mud to rotate centrifugally, so that the mud can undergo preliminary mud-water separation.

[0062] S3: Then control the second electric push rod 4 to retract so that it drives the bottom plate 2021 to flip. The bottom of the filter cylinder 6 is open at this time. Control the second motor 8 to run. The second motor 8 drives the spiral conveying blade 802 on the outside of the conveying shaft 801 to rotate, so that the spiral conveying blade 802 presses down and conveys the mud blocks that have been initially separated from the mud and water in the filter cylinder 6. As the inner diameter of the filter cylinder 6 gradually shrinks, the water in the mud blocks is further squeezed out and enters the water receiving shell 5. The mud blocks removed from the filter cylinder 6 are cut into several strips by the wire mesh frame 2022. Then the cut mud blocks fall to the bottom of the mixing cylinder 1.

[0063] S4: Then control the first electric push rod 3 to push the separation cylinder 2 to move back and forth in the mixing cylinder 1, control the cylinder unblocking component to work, unblock the filter holes of the filter screen cylinder 6, and remove the mud from the filter holes.

[0064] S5: When the separating cylinder 2 moves back and forth, it drives the annular powder box 12 to move, causing the curing agent powder in the annular powder box 12 to shake and loosen. When the cylinder unblocking component works, it drives the powder mixing component to work, so that the curing agent powder in the annular powder box 12 is fully mixed with the mud block removed from the filter cylinder 6.

[0065] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0066] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

Several stirring blades (151) are evenly arranged on the collars (15) in a circular pattern. The inner sidewall of the collars (15) is fixed with guide blocks (152) that slide with the spiral track grooves (141).

2. The channel dredging mud solidification device according to claim 1, characterized in that, The separation cylinder (2) also includes a discharge mechanism disposed in the filter cylinder (6), a first motor (7) fixed in the water receiving shell (5), a drive gear (701) disposed on the output shaft of the first motor (7), and a driven gear (702) fixed to the top of the filter cylinder (6). The feed inlet (201) and the discharge outlet (202) are respectively disposed at the top and bottom of the filter cylinder (6), and a wire mesh frame (2022) is disposed on the discharge outlet (202).

3. The channel dredging mud solidification device according to claim 2, characterized in that, The discharge mechanism includes a second motor (8) fixed at the top of the filter cylinder (6), a conveying shaft (801) connected to the output shaft of the second motor (8) and rotatably connected inside the filter cylinder (6), and a spiral conveying blade (802) fixed on the conveying shaft (801). The spiral conveying blade (802) moves against the inner wall of the filter cylinder (6), and the diameter of the filter cylinder (6) gradually decreases from top to bottom.

4. The channel dredging mud solidification device according to claim 3, characterized in that, The inner wall of the annular powder box (12) is provided with several through holes (121), and the right cavity of the fixed tube (10) is connected to the annular powder box (12) by an exhaust pipe (122), and a second exhaust valve is provided in the exhaust pipe (122).

5. A channel dredging mud solidification device according to claim 4, characterized in that, The outer side of the collar (15) is fixed with a protective tube (16) sleeved on the outside of the positioning rod (14) for covering the spiral track groove (141).

6. A method for solidifying dredging mud, comprising processing the dredging mud using the device described in claim 5, characterized in that... Includes the following steps: S1: Connect the pipe for discharging mud to the feed inlet (201) at the top of the separator (2), and then discharge the mud into the separator (2); S2: Control the operation of the first motor (7). When the first motor (7) is running, it drives the active gear (701) to mesh with the driven gear (702) on the filter screen cylinder (6), thereby causing the filter screen cylinder (6) to drive the mud to rotate centrifugally, so that the mud can undergo preliminary mud-water separation. S3: Then control the second electric push rod (4) to retract so that it drives the bottom plate (2021) to flip. The bottom of the filter cylinder (6) is open at this time. Control the second motor (8) to run. The second motor (8) drives the spiral conveying blade (802) on the outside of the conveying shaft (801) to rotate, so that the spiral conveying blade (802) presses down and conveys the mud block that has been initially separated from the mud and water in the filter cylinder (6). As the inner diameter of the filter cylinder (6) gradually shrinks, the water in the mud block is further squeezed out and enters the water receiving shell (5). The mud block removed from the filter cylinder (6) is cut into several strips by the wire mesh frame (2022). Then the cut mud block falls to the bottom of the mixing cylinder (1). S4: Then control the first electric push rod (3) to push the separation cylinder (2) to move back and forth in the mixing cylinder (1), control the cylinder unblocking component to unblock the filter holes of the filter screen cylinder (6) and remove the mud from the filter holes; S5: When the separation cylinder (2) moves back and forth, it drives the annular powder box (12) to move, causing the curing agent powder in the annular powder box (12) to shake and loosen. When the cylinder unblocking component works, it drives the powder mixing component to work, so that the curing agent powder in the annular powder box (12) is fully mixed with the mud block removed from the filter cylinder (6).
