Description

Technical Field

[0001] This invention relates to the field of recycled soil processing technology, and in particular to a device for dewatering and solidifying high-concentration recycled soil slurry. Background Technology

[0002] Reclaimed soil is a type of soil material that has been recovered and reused from waste or contaminated soil through a series of physical, chemical, or biological treatment processes, and possesses certain engineering or agricultural value. This waste soil may originate from processes such as building demolition, road excavation, mining, or contaminated site remediation. The treatment process for reclaimed soil typically includes steps such as screening, crushing, removal of harmful substances (such as heavy metals and organic pollutants), adjustment of particle size distribution, and improvement of physicochemical properties. The aim is to eliminate its original unfavorable characteristics and enhance its engineering stability, bearing capacity, or fertility. Ultimately, reclaimed soil can be used in land reclamation, roadbed filling, landscaping, and building backfilling projects, thereby reducing the consumption of native natural soil and mitigating the environmental pressure from solid waste accumulation. It represents a resource utilization method that aligns with the principles of a circular economy.

[0003] Currently, in the field of recycled soil treatment, the dehydration and solidification of high-concentration slurry is a crucial step. Existing treatment equipment typically involves loading high-concentration slurry into high-fiber bags and then manually squeezing it for dehydration and solidification. However, this manual and intermittent treatment method is not only labor-intensive but, more importantly, cannot achieve continuous operation. This significantly limits the dehydration and solidification efficiency of recycled soil, making it difficult to meet the needs of large-scale, high-efficiency treatment. Summary of the Invention

This invention addresses the problem mentioned in the background that existing treatment devices typically involve loading high-concentration slurry into high-fiber cloth bags and then manually squeezing it for dewatering and solidification. However, this manual and intermittent treatment method is not only labor-intensive but, more importantly, cannot achieve continuous operation, which significantly limits the dewatering and solidification efficiency of recycled soil and makes it difficult to meet the needs of large-scale, high-efficiency treatment.

[0008] The dehydration drive mechanism includes a drive motor, a rotating roller, and a fixed plate. The fixed plate is fixedly installed on one side surface of the extrusion plate. The drive motor is fixedly installed on the upper side of the dehydration container via a mounting bracket. The rotating roller is driven and installed at the output end of the drive motor via a transmission shaft. Several sets of drainage holes are opened on the surface of the dehydration container. High-fiber fabric is fixedly installed on the inner wall of the dehydration container.

[0009] The discharge mechanism includes a discharge guide plate and an insert plate. The lower part of the dehydration container has a slot, and the insert plate is slidably installed inside the slot.

[0010] The discharge drive mechanism includes a rotating disk, a transmission rod, and a rotating shaft. The rotating disk is fixedly installed at both ends of the transmission shaft. The transmission rod is movably installed at the lower part of the rotating disk via a rotating rod. A third tooth block is fixedly installed on the side surface of the rotating shaft. Connecting plates are fixedly installed on both sides of the insert plate. A fourth tooth block is fixedly installed on the upper surface of the connecting plate.

[0011] Preferably, the feeding mechanism includes a feeding pipe and a control valve, the control valve being installed inside the feeding pipe, and the feeding pipe being fixedly installed through and on one side of the dehydration container.

[0012] Preferably, a spring structure is installed on the side surface of the telescopic rod, and the shape and area of ​​the extrusion plate are the same as the shape and area of ​​the internal space of the dehydration container.

[0013] Preferably, a first toothed block is fixedly installed on the side surface of the rotating roller, the first toothed block is located at half position of the side surface of the rotating roller, and a second toothed block is fixedly installed on the outer surface of the fixing plate, the fixing plate meshing with the rotating roller through the second toothed block and the first toothed block.

[0014] Preferably, discharge guide plates are fixedly installed on both sides of the lower surface of the dehydration container.

[0015] Preferably, the lower part of both sides of the outer casing of the equipment is hinged with a discharge box door.

[0016] Preferably, the upper end of the rotating rod is rotatably mounted on the outer surface of the rotating disk, and the lower end of the rotating rod is rotatably mounted on the upper end of the transmission rod.

[0017] Preferably, limit rods are fixedly installed on both sides of the lower inner surface of the outer casing of the equipment, and a limit groove is formed on the outer surface of the transmission rod, with the limit rod slidably connected inside the limit groove.

[0018] Preferably, the transmission rod meshes with the rotating shaft through a toothed block fixedly mounted on its side surface, and the rotating shaft meshes with the connecting plate through a third toothed block and a fourth toothed block.

[0019] Preferably, the lower inner surface of the equipment casing is provided with water channels on both sides, and a drain pipe is fixedly installed on one side of the equipment casing.

[0020] The beneficial effects of this invention are:

[0021] This invention utilizes a dewatering mechanism and a dewatering drive mechanism. During use, a high-concentration recycled soil slurry is fed into the dewatering container via a feeding mechanism. A drive motor rotates the transmission shaft, which in turn drives a rotating roller. As the roller rotates, the first toothed block on its surface meshes with the second toothed block on the outer side of the fixed plate, causing the fixed plate and the extrusion block to slide downwards. The extrusion block then extrudes and dewaters the high-concentration recycled soil slurry inside the dewatering container, allowing water to flow out through the high-fiber cloth installed on the inner wall of the container. The recycled soil inside solidifies after dewatering. As the rotating roller continues to rotate, when the rotating rod reaches the surface without toothed blocks, the spring structure pulls the extrusion block upwards to reset it, completing a single dewatering and solidification operation of the recycled soil. This eliminates the need for manual extrusion, improving the efficiency of recycled soil processing and making the operation more convenient.

[0022] This invention, through its designed discharge mechanism and discharge drive mechanism, allows the high-concentration recycled soil slurry to be dehydrated and solidified. A drive motor then rotates the transmission shaft and rotating disk. The rotating disk pulls the transmission rod via a rotating rod, causing the transmission rod to slide upwards. The transmission rod, through the meshing of its side surface teeth with the third tooth on the rotating shaft surface, drives the rotating shaft to rotate clockwise. The rotating shaft, through the meshing of the third tooth with the fourth tooth on the connecting plate surface, causes the connecting plate to slide outwards, resulting in the middle insert plate sliding outwards. This allows the dehydrated and solidified recycled soil inside the dehydration container to fall downwards, achieving automatic discharge. As the rotating disk continues to rotate, it drives the transmission rod downwards via the rotating rod. The transmission rod, through the teeth and the third tooth, drives the rotating shaft to rotate counterclockwise, ultimately achieving the purpose of the insert plate sliding inwards inside the slot, sealing the bottom of the dehydration container for subsequent extrusion, dehydration, and solidification. This invention achieves automatic discharge and sealing reset of the dehydrated and solidified recycled soil, simplifying operation and improving processing efficiency and continuity.

[0023] This invention, through the setting of a discharge guide plate and a drain pipe, allows the high-concentration recycled soil slurry to be squeezed, dehydrated, and solidified inside the dehydration container. The water inside flows out through the dehydration container and then flows downward through the discharge guide plate into the water channels on both sides of the lower part of the outer casing of the equipment. It then flows out along the water channels toward the drain pipe until all the water inside the outer casing of the equipment is drained. After the insert plate is opened, the dehydrated and solidified recycled soil inside the dehydration container falls downward, and the discharge box door can be opened to remove the dehydrated and solidified recycled soil cake. This simplifies the process of removing the solidified soil and improves the overall ease of operation. Attached Figure Description

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0034] refer to Figure 1-7 A device for dewatering and solidifying high-concentration recycled soil slurry includes the following embodiments:

[0035] Example 1:

[0036] A high-concentration recycled soil slurry dewatering and solidification device includes an outer casing 1, a feeding mechanism 2, a dewatering mechanism 3, a dewatering drive mechanism 4, a discharging mechanism 5, and a discharging drive mechanism 6. The dewatering mechanism 3 includes a dewatering container 304 and an extrusion plate 303. The extrusion plate 303 is movably installed in the upper inner part of the outer casing 1 via a telescopic rod 301. The dewatering container 304 is fixedly installed in the middle inner part of the outer casing 1. The feeding mechanism 2 includes a feeding pipe 201 and a control valve 202. The control valve 202 is installed inside the feeding pipe 201. The feeding pipe 201 is fixedly installed through one side of the dewatering container 304. A spring structure 302 is installed on the side surface of the telescopic rod 301. The shape and area of ​​the extrusion plate 303 are the same as the shape and area of ​​the internal space of the dewatering container 304.

[0037] Example 2:

[0038] The dehydration drive mechanism 4 includes a drive motor 402, a rotating roller 404, and a fixed plate 406. The fixed plate 406 is fixedly installed on one side surface of the extrusion plate 303. The drive motor 402 is fixedly installed on the upper side of the dehydration container 304 via a mounting bracket 401. The rotating roller 404 is driven and installed at the output end of the drive motor 402 via a transmission shaft 403. Several sets of drainage holes 305 are opened on the surface of the dehydration container 304. High-fiber fabric is fixedly installed on the inner wall of the dehydration container 304. A first toothed block 405 is fixedly installed on the side surface of the rotating roller 404, and the first toothed block 405 is located at half of the side surface of the rotating roller 404. A second toothed block 407 is fixedly installed on the outer surface of the fixed plate 406. The fixed plate 406 meshes with the rotating roller 404 through the second toothed block 407 and the first toothed block 405. The present invention, through the dehydration mechanism 3 and the dehydration drive mechanism 4, enables the use of... The high-concentration recycled soil slurry is fed into the dewatering container 304 through the feeding mechanism 2. The drive motor 402 drives the transmission shaft 403 to rotate, which in turn drives the rotating roller 404 to rotate. When the rotating roller 404 rotates, the first toothed block 405 on its surface meshes with the second toothed block 407 on the outer side of the fixed plate 406, thereby causing the fixed plate 406 and the extrusion block to slide downward. The extrusion block extrudes and dewaters the high-concentration recycled soil slurry in the dewatering container 304, allowing water to flow out through the high-fiber cloth installed on the inner wall of the dewatering container 304. The recycled soil inside is dewatered and solidified. As the rotating roller 404 continues to rotate, when the rotating rod 602 rotates to the surface without toothed blocks, the spring structure 302 pulls the extrusion block upward to reset it, completing a single dewatering and solidification operation of the recycled soil. No manual extrusion is required, which improves the efficiency of recycled soil processing and makes the operation more convenient.

[0039] Example 3:

[0040] The discharge mechanism 5 includes a discharge guide plate 502 and an insert plate 504. A slot 503 is provided in the lower inner part of the dewatering container 304. The insert plate 504 is slidably installed inside the slot 503, and its length is slightly longer than the slot 503. Discharge guide plates 502 are fixedly installed on both sides of the lower surface of the dewatering container 304. Discharge boxes 501 are hinged to the lower parts of both sides of the outer casing 1. Through the discharge guide plates 502 and the drain pipe, the high-concentration recycled soil slurry is squeezed and dewatered inside the dewatering container 304. During water solidification, the water inside the container flows out through the dewatering container 304 and then flows downward through the discharge guide plate 502 into the water troughs on both sides of the lower part of the outer casing 1 of the equipment. The water flows down the water troughs and is discharged towards the drain pipe until all the water inside the outer casing 1 of the equipment is discharged. After the insert plate 504 is opened, the dewatered and solidified recycled soil inside the dewatering container 304 falls downward, and the discharge box door 501 can be opened to remove the dewatered and solidified recycled soil cake. This simplifies the process of removing the solidified soil and improves the overall ease of operation.

[0041] Example 4:

[0042] The discharge drive mechanism 6 includes a rotating disk 601, a transmission rod 603, and a rotating shaft 606. The rotating disk 601 is fixedly installed at both ends of the transmission shaft 603. The transmission rod 603 is movably installed at the lower part of the rotating disk 601 via a rotating rod 602. A third toothed block 607 is fixedly installed on the side surface of the rotating shaft 606. Connecting plates 608 are fixedly installed on both sides of the insert plate 504. A fourth toothed block 609 is fixedly installed on the upper surface of the connecting plate 608. The upper end of the rotating rod 602 is rotatably installed on the outer surface of the rotating disk 601, and the lower end of the rotating rod 602 is rotatably installed on the upper end of the transmission rod 603. Limiting rods 605 are fixedly installed on both sides of the lower inner surface of the box 1. A limiting groove 604 is formed on the outer surface of the transmission rod 603. The limiting rods 605 are slidably connected inside the limiting groove 604. The transmission rod 603 meshes with the rotating shaft 606 through toothed blocks fixedly installed on its side surface. The rotating shaft 606 meshes with the connecting plate 608 through third toothed blocks 607 and fourth toothed blocks 609. Water channels are formed on both sides of the lower inner inner surface of the outer box 1. A drain pipe is fixedly installed on one side of the outer box 1. This invention, through the provided discharge mechanism 5 and discharge drive mechanism 6, produces high-concentration recycled soil. After the mud undergoes dewatering and solidification, the drive motor 402 drives the transmission shaft 403 and the rotating disk 601 to rotate. The rotating disk 601 pulls the transmission rod 603 through the rotating rod 602, causing the transmission rod 603 to slide upward. The transmission rod 603 engages with the third tooth block 607 on the surface of the rotating shaft 606 through the toothed blocks on its side surface, thereby driving the rotating shaft 606 to rotate clockwise. The rotating shaft 606 engages with the fourth tooth block 609 on the surface of the connecting plate 608 through the third tooth block 607, thereby driving the connecting plate 608 to slide outward, causing the middle insert plate 504 to slide outward, thus achieving dewatering. The dehydrated and solidified recycled soil inside container 304 falls downwards for automatic discharge. As the rotating disk 601 continues to rotate, the rotating disk 601 drives the transmission rod 603 to slide downwards via the rotating rod 602. The transmission rod 603 drives the rotating shaft 606 to rotate counterclockwise via the toothed block and the third toothed block 607. This ultimately achieves the purpose of the insert plate 504 sliding inwards inside the slot 503, sealing the bottom of the dehydration container 304, facilitating the next extrusion dehydration and solidification process. This achieves automatic discharge and sealing reset of the dehydrated and solidified recycled soil, simplifying operation and improving processing efficiency and continuity.

[0043] During operation, the operator uses the feed pipe 201 and its internal control valve 202 to control the feeding of the high-concentration recycled soil slurry to be treated into the dewatering container 304, which is fixedly installed in the middle part of the equipment outer casing 1. The inner wall of the dewatering container 304 is pre-fixed with high-fiber cloth, and its surface is also provided with several sets of drainage holes 305 to prepare for subsequent dewatering. The middle space inside the dewatering container 304 is identical in shape and area to the upper extrusion plate 303. The extrusion plate 303 is movably installed in the upper part of the equipment outer casing 1 via a telescopic rod 301, and the spring structure 302 installed on the side surface of the telescopic rod 301 is in a pre-compressed state to provide power for resetting after extrusion. Next, the dewatering and solidification stage begins, driven by the motor 402. Upon startup, the drive shaft 403 connected to its output end drives the rotating roller 404 to rotate. The first toothed block 405, fixedly installed at half of the side surface of the rotating roller 404, meshes with the second toothed block 407 fixed to the outside of the fixed plate 406 on one side surface of the extrusion plate 303. As the rotating roller 404 continues to rotate, the first toothed block 405 pushes the second toothed block 407, causing the fixed plate 406 and the connected extrusion plate 303 to slide downward as a whole. The extrusion plate 303 moves downward and presses tightly against the high-concentration slurry already loaded in the dewatering container 304, subjecting it to strong extrusion. Under the extrusion action, the water in the slurry is squeezed out. This water passes through the high-fiber cloth on the inner wall of the dewatering container 304 and flows out through the drainage holes 305 on the surface of the container. The flowing water will come into contact with the discharge guide plate 502 below, and flow along the guide plate into the water troughs on both sides of the lower part of the equipment outer box 1. Finally, it will flow along the water troughs to the drain pipe and be discharged from the equipment outer box 1, ensuring that the environment inside the box is dry. After the squeezed high-concentration recycled soil slurry loses a lot of water, it gradually dehydrates and solidifies to form a mud cake. When the rotating roller 404 continues to rotate, when the first tooth block 405 on its surface rotates to the area not covered by the tooth block, it disengages from the fixed plate 406. At this time, the reset elastic force of the spring structure 302 on the telescopic rod 301 begins to play, pulling the extrusion plate 303 upward to return it to its initial position, completing one cycle of extrusion, dehydration and solidification of the high-concentration recycled soil slurry, preparing for the next feeding and extrusion. The entire process requires no manual intervention or extrusion, significantly improving processing efficiency. After one round of dehydration and solidification, it enters the automatic discharge stage. Again, the drive motor 402 operates, but this time the transmission shaft 403 drives the two rotating discs 601 fixed at both ends to rotate synchronously. The rotating rod 602, movably mounted on the outer surface of the rotating disc 601, rotates accordingly. The lower end of the rotating rod 602 is connected to the transmission rod 603. A limiting groove 604 is provided on the outer side of the transmission rod 603, which fits precisely onto the limiting rods 605 fixed on both sides of the lower inner surface of the outer casing 1 of the equipment, serving as a guide and limiting element. When the rotating disc 601 rotates, the rotating rod 602 pulls the transmission rod 603 to slide up and down along the limiting rod 605. Initially, the transmission rod 603 is pulled upwards.The toothed block fixedly installed on its side surface will mesh with the third toothed block 607 on the side surface of the rotating shaft 606. This meshing action drives the rotating shaft 606 to rotate clockwise. The third toothed block 607 on the rotating shaft 606 will then mesh with the fourth toothed block 609 installed on the connecting plates 608 on both sides of the insert plate 504, thereby driving the connecting plate 608 to slide outward, which in turn drives the insert plate 504 located in the lower slot 503 inside the dewatering container 304 to slide outward. After the slot 503 is pulled out and the insert plate 504 is removed, the opening at the bottom of the dewatering container 304 opens, and the dewatered and solidified recycled soil cake inside the container falls smoothly downward along the discharge guide plate 502 under the action of gravity. As the rotating disk 601 continues to rotate, the rotating rod 602 will be driven to slide downward. At this time, the transmission... The toothed block on the side surface of the moving rod 603 meshes counter-clockwise with the third toothed block 607 of the rotating shaft 606, causing the rotating shaft 606 to rotate counter-clockwise. This counter-clockwise rotation of the rotating shaft 606, through the meshing of the third toothed block 607 with the fourth toothed block 609, drives the connecting plate 608 to slide inwards, ultimately causing the insert plate 504 to slide back into the slot 503, sealing the bottom of the dewatering container 304 and preparing it for the next extrusion dewatering and solidification process. At this point, the operator only needs to open the discharge box door 501 hinged to the lower part of both sides of the outer casing 1 to easily remove the dewatered and solidified recycled soil cake that has fallen below. The entire process achieves continuous and automated operation from feeding, automatic extrusion dewatering and solidification, automatic drainage, automatic discharge to automatic sealing.
