The mud usually needs to be transported to a designated location for flocculation conditioning and bag filling, which results in a long transportation pipeline, low treatment efficiency, and the need to add multiple mud pumps to increase transportation capacity and increase costs. The dehydrated liquid usually needs to be collected and specially treated before it can be discharged to meet the standards.

[0005] Plate and frame filter press: In a closed state, the mud pumped in by the high-pressure pump is squeezed by the plate and frame to discharge the water to achieve the purpose of dehydration.

At this time, the float will rise with the water level, causing the slider 17 to move upward, thereby pushing the gas in the hollow block 16 from the connecting pipe 11 into the hollow block 16. At this time, the push rod 14 will push the sodium hypochlorite effervescent tablets under the push of the gas, causing the sodium hypochlorite effervescent tablets to fall from the vertical end of the storage tank 12, and then be discharged from the discharge tank into the water. As the water level continues to rise, the gas in the hollow block 16 will continue to enter the hollow rod 13, allowing the push rod 14 to push the sodium hypochlorite effervescent tablets into the water according to the water level, so as to achieve the effect of automatically placing appropriate sodium hypochlorite effervescent tablets according to the water level.

When the slide plate 20 moves to the sealing plate 18, the magnetic strip 22 will be magnetically attracted to the card block 23, so that the card block 23 is separated from the card slot. At this time, the push plate will move upward to push the gas into the storage tank 12, and exert pressure on the water reacting with the sodium hypochlorite effervescent tablet, so as to push the sealing plate 18 open, so that the water reacting with the sodium hypochlorite effervescent tablet can be flushed into the depth of the clean water. After that, the sealing plate 18 will be reset under the action of the torsion spring and squeeze the first elastic block 25. At this time, the gas in the first spring block will enter the second slide groove 24 from the conduit 26 to push the card block 23, so that the card block 23 is engaged with the card slot.

At this time, the gas pushes the moving block 35, so that the moving block 35 drives the driving plate 32 to move. When the push rod 14 drives the movable plate 33 to reset, the gas in the hollow groove 30 will be sucked into the storage tank 12, and the movable block 35 will be sucked and reset. At the same time, when the movable block 35 is reset, the offset component will make the driving plate 32 move upward and no longer contact the ball 31. After the movable block 35 is completely reset, the driving plate 32 is allowed to contact the ball 31 again.

When the driving plate 32 needs to contact the ball 31, the electromagnet 36 is turned off, and the driving plate 32 will rotate downward to contact the ball 31.

[0041] Working principle: The movable dredged sludge cleaning and dehydration device in the present application realizes the cleaning and dehydration of dredged sludge in the form of a container in a vehicle carrier 1, and can reduce the moisture content of dredged sludge with a moisture content of more than 95% to less than 70% and transport it out in time, while realizing the cleaning treatment of the dehydrated liquid and realizing real-time discharge into the river. The reagent barrel 5 is filled with an ionic polymer flocculant with a concentration of 0.3wt%. The sludge discharge module 8 is in a normally closed state during dehydration operation. The sludge is first sucked into the stirring barrel 6 by means of a sludge pump, and then the automatic control module 7 adds the flocculant in the reagent barrel 5 to the stirring barrel 6. The stirring barrel 6 is controlled by the automatic control module 7 to perform stirring, so that the sludge and the flocculant are stirred, and then discharged into the sedimentation tank 3 for sedimentation for 6 hours to 7 hours. The supernatant precipitated in the sedimentation tank 3 will be discharged into the clean water tank 4. When the liquid in the clean water tank 4 reaches the set height, the automatic control module 7 controls the sodium hypochlorite effervescent tablet storage module 9 so that the sodium hypochlorite effervescent tablet storage module 9 adds sodium chlorate effervescent tablets into the water. After the reaction and standing for 1 hour, the treated clean water is discharged back to the river. The drainage pipe arranged on the side wall of the clean water tank 4 can be connected to the external pipeline for drainage. Each box body is integrated in the container, and the mobile function is realized by the car carrier 1. When the dehydrated liquid is drained from the sedimentation tank 3, the car is moved to the designated location, and the bottom mud discharge module 8 is opened by the automatic control module 7. After the remaining bottom mud is discharged and dried for 15 days, it can be reused in farmland, landscaping or landfill according to the water content and heavy metal content.

[0042] When the water level in the clean water tank 4 in the present application rises, the water level will reach the slider 17. At this time, the float will rise with the water level, so that the slider 17 moves upward, thereby pushing the gas in the hollow block 16 from the connecting pipe 11 into the hollow block 16. At this time, the push rod 14 will push the sodium hypochlorite effervescent tablet under the push of the gas, so that the sodium hypochlorite effervescent tablet falls from the vertical end of the storage tank 12, and then is discharged from the discharge tank into the water. As the water level continues to rise, the gas in the hollow block 16 will continue to enter the hollow rod 13, so that the push rod 1 4 pushes the sodium hypochlorite effervescent tablet into the water according to the water level, so as to achieve the effect of automatically adding the appropriate sodium hypochlorite effervescent tablet according to the water level; in the process of the water level rising in the present application, water will enter the storage tank 12 from the water inlet hole, and then when the push rod 14 pushes the sodium hypochlorite effervescent tablet to enter the vertical end of the storage tank 12, the sodium hypochlorite effervescent tablet will enter the water, and at this time, the sodium hypochlorite effervescent tablet will react with water to produce gas, and at this time, the gas will enter the first slide groove 19 to push the slide plate 20, and after the sodium hypochlorite effervescent tablet reacts with water for a period of time, the seal The mechanism is opened, and the slide plate 20 is reset upward under the push of the third spring, thereby pushing the gas in the first slide groove 19 from the connecting groove 21 into the storage groove 12. At this time, the water in the storage groove 12 that reacts with the sodium hypochlorite effervescent tablet will be pushed and injected into the deep water under the action of air pressure, thereby promoting the sodium hypochlorite effervescent tablet to react more fully in the water; when the sodium hypochlorite effervescent tablet in the present application reacts with water to produce gas, the gas will push the slide plate 20 to move downward, and when the slide plate 20 moves to the sealing plate 18, the magnetic strip 22 will be magnetically attracted to the card block 23, so that the card block 23 is separated from the card slot. At this time, the push plate will move upward to push the gas into the storage tank 12, and exert pressure on the water reacting with the sodium hypochlorite effervescent tablet, so as to push the sealing plate 18 open, so that the water reacting with the sodium hypochlorite effervescent tablet can be flushed into the depth of the clean water. After that, the sealing plate 18 will be reset under the action of the torsion spring and squeeze the first elastic block 25. At this time, the gas in the first spring block will enter the second slide groove 24 from the conduit 26 to push the card block 23, so that the card block 23 is engaged with the card slot;

[0043] In the present application, when water enters the storage tank 12, the water will enter the sealing plate 18 from the through hole 27 on the sealing plate 18, and then enter the second elastic block 29 through the square hole and the connecting hole 28. Then, when the sealing plate 18 rotates downward, the sealing plate 18 will squeeze the second elastic block 29, so that the water in the second elastic block 29 can enter the sealing plate 18. At this time, the water in the sealing plate 18 will be sprayed out from the through hole 27.
