Description

Technical Field

[0001] This invention relates to the field of tunnel boring machine (TBM) slurry technology, specifically to a sedimentation and pressing treatment device for the recycling and reuse of TBM slurry. Background Technology

[0002] A tunnel boring machine (TBM) is a type of tunnel boring machine that uses the shield tunneling method. The shield tunneling method involves the TBM constructing supporting tunnel segments while excavating, which differs from the open tunneling method. The shield slurry is made by mixing water, clay, and additives. It is used to maintain the stability of the excavation face during shield tunneling. Water serves as the basic solvent, clay provides the necessary viscosity and suspension, and additives are used to adjust the properties of the slurry, such as thickeners and dispersants, to meet the construction needs under different geological conditions.

[0003] During the operation of tunnel boring machines (TBMs), a large amount of slurry is required. After the slurry is used, it needs to be treated again to prevent pollution and damage to the surrounding environment. This often involves sedimentation and pressing equipment. However, some existing sedimentation and pressing equipment suffers from problems during operation. The slurry directly enters the settling area during transport, impacting the equipment and potentially creating turbulent dead zones. Fine particles are then swept away by the turbulent flow and fail to settle, resulting in reduced slurry settling efficiency. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-10 As shown, a sedimentation and pressing treatment device for the recycling of slurry from tunnel boring machines includes a bottom box 1. Inside the bottom box 1, collection boxes 4 are installed to collect particles discharged from the slag hopper 605, facilitating unified processing by workers. Simultaneously, the bottom of the slurry outlet pipe 702 is connected to the inlet of a plate and frame filter press 5, allowing the settled slurry to enter the plate and frame filter press 5 for further processing. The device also includes: A sealing cover 2 is installed on the front surface of the bottom box 1. Under the function of the sealing cover 2, it facilitates the cleaning and maintenance of the collection box 4 and the plate and frame filter press mechanism 5 by personnel. A PLC controller 3 is installed on one side of the bottom box 1. The PLC controller 3 is connected to the drive motor, conveying pump 18, first valve 8, second valve 12 in the stirring mechanism 33, and the plate and frame filter press in the plate and frame filter press mechanism 5 via wires. Simultaneously, the PLC controller 3 can control the normal operation of the drive motor, conveying pump 18, first valve 8, second valve 12, and plate and frame filter press in the stirring mechanism 33 and the plate and frame filter press in the plate and frame filter press mechanism 5. The above should be considered prior art. The specific structure, working principle, and possible control methods of these technical features are described below. The conventional choice in terms of layout and spatial arrangement is sufficient, and this technical solution will not be further elaborated in detail. The bottom of the inner cavity of the bottom box 1 is respectively provided with a collection box 4 and a plate and frame filter press mechanism 5. The plate and frame filter press mechanism 5 mainly includes a plate and frame filter press, which is a device that achieves solid-liquid separation through pressure. Its core principle is to use filter plates and filter frames to form a closed filter chamber. Under the pressure applied by the hydraulic system, the liquid in the suspension passes through the filter cloth and is discharged, while the solid particles are trapped in the filter chamber to form a filter cake. Its important components include filter plates, filter frames, filter cloth and hydraulic system, which can then compress the sludge that has completed the sedimentation operation to form a mud cake, and then further treat the discharged water. The pretreatment component 6, under its function, allows the mud-water conveyed through the feed pipe 11 to be filtered twice. Through the combined action of the filter screen 603 and the filter cylinder 604, the mud-water is pretreated to prevent large particles of impurities from affecting subsequent settling operations. Located at the top of the bottom tank 1, the pretreatment component 6 includes a pretreatment tank 601 fixedly connected to the top of the bottom tank 1. The pretreatment tank 601 performs pretreatment of the mud-water to prevent large particles of impurities from affecting subsequent settling operations. A slag discharge pipe 602 is fixedly connected inside the pretreatment tank 601. Some impurities and particles settled inside the slag hopper 605 can be discharged, allowing them to enter the collection box 4. This facilitates the processing of the particles and impurities collected in the slag hopper 605 by the staff. The pretreatment tank 601 is equipped with a filter screen 603, which intercepts large impurities to prevent them from entering the subsequent structure. The bottom of the filter screen 603 is equipped with a filter cylinder 604, which filters smaller medium-sized impurities to further purify the mud and water, facilitating subsequent processing. The top of the slag discharge pipe 602 is connected to the slag hopper 605. The settling assembly 7 utilizes centrifugal force to pre-separate the mud and water, causing large particles to be quickly thrown to the tank wall, reducing the subsequent settling load. A stable mud-water flow is then constructed through multiple settling pans 705, allowing fine particles to settle rapidly within the pans. Located at the top of the bottom tank 1, the settling assembly 7 includes a settling tank 701 fixedly connected to the top of the bottom tank 1. The settling tank 701 ensures the stable placement and proper functioning of all components within the settling assembly 7, thereby treating the mud and water. A sludge discharge pipe 702 is fixedly connected inside the settling tank 701, discharging the sludge collected in the sludge hopper 28. The sludge then enters the plate and frame filter press 5, where it is pressed to remove impurities. The sedimentation tank 701 is equipped with a connecting pipe 703 at the top. Under the action of the connecting pipe 703, the conveying pump 18 can extract the mud and water in the slag hopper 605 and then transport the mud and water to the interior of the sedimentation tank 701 through the connecting pipe 703 for sedimentation. The inner wall of the sedimentation tank 701 is fixedly connected to a clear water ring 704. Under the action of the clear water ring 704, the clear water collected inside the central water collection pipe 22 can be collected and then transported through the clear water ring 704. The interior of the sedimentation tank 701 is equipped with three sedimentation plates 705. The outer side of the sedimentation plates 705 is fixedly connected to a support. Under the action of the support, the sedimentation plates 705 can be placed stably. At the same time, under the action of multiple sedimentation plates 705, fine particles settle quickly over a short distance.

[0020] A first valve 8 is installed on the outside of the slag discharge pipe 602. The operation of the slag discharge pipe 602 can be controlled by the first valve 8, thereby discharging the particulate impurities collected inside the slag hopper 605. A rotating pipe 9 is rotatably connected to the bottom of the filter screen 603. Multiple rotating pipes 9 can connect the rotating pipe 9 to the connecting rod 36, thus ensuring a tight connection between the filter screen 603 and the filter cylinder 604. This facilitates the cleaning or replacement of the filter cylinder 604 and the filter screen 603 by the operators. The rotating pipe 9 is internally threaded with the connecting rod 36. Under the action of the connecting rod 36, the rotating pipe 9 rotates... After a specified number of rotations, the connecting rod 36 and the rotating tube 9 are stably connected. The bottom of the connecting rod 36 is fixedly connected to the top of the filter cylinder 604. Through the connecting rod 36 and the rotating tube 9, the filter cylinder 604 and the filter screen 603 are tightly connected. A top plate 10 is fixedly connected to the top of the pretreatment tank 601. Under the action of the top plate 10, the pretreatment tank 601 can be sealed to prevent mud and water from splashing everywhere during the pretreatment process. A feed pipe 11 is fixedly connected inside the top plate 10. Under the action of the feed pipe 11, the shield tunnel mud and water can be transported, allowing the mud and water to enter the interior of the pretreatment tank 601 through the feed pipe 11 for processing. Water pretreatment is performed. A second valve 12 is installed on the outside of the feed pipe 11. The normal operation of the feed pipe 11 can be controlled by the second valve 12. A buffer plate 13 is fixedly connected to the bottom of the top plate 10. The number of buffer plates 13 is set to four. Under the action of multiple buffer plates 13, the mud and water discharged through the feed pipe 11 can be blocked, thereby reducing the kinetic energy carried by the mud and water. A positioning frame 14 is fixedly connected to the top of the filter screen 603. Under the action of the positioning frame 14, it is convenient for the staff to position and place the filter screen 603, and it is also convenient for the staff to handle the filter screen 603. 03. Disassembly is performed. The positioning frame 14 has a positioning bolt 15 connected to its internal thread. When the operator needs to disassemble the filter screen 603, first rotate the positioning bolt 15, which will cause the positioning bolt 15 to disengage from the positioning frame 14 and the interior of the pretreatment tank 601, thereby pulling the filter screen 603 and causing the filter screen 603 to disengage from the interior of the pretreatment tank 601. The interior of the pretreatment tank 601 has a positioning groove 16 that works with the positioning frame 14. The inner wall of the positioning groove 16 is slidably connected to the outer side of the positioning frame 14. With the action of multiple positioning grooves 16, it is convenient for the operator to install and position the filter screen 603 through multiple positioning frames 14.

[0021] The pretreatment tank 601 has a positioning hole 17 inside. By rotating the positioning bolt 15, the positioning bolt 15 can enter or leave the positioning hole 17, which makes it convenient for workers to disassemble and install the filter screen 603 through the positioning bolt 15. The inner wall of the positioning hole 17 is threadedly connected to the outer side of the positioning bolt 15.

[0022] A conveying pump 18 is fixedly connected to the top of the bottom box 1. Under the action of the conveying pump 18, its inlet is connected to the upper part of the slag hopper 605, so that the sludge and water that has settled inside the slag hopper 605 can be extracted and then conveyed. The inlet of the conveying pump 18 is connected to the slag hopper 605, and the outlet of the conveying pump 18 is connected to the end of the connecting pipe 703 away from the ring pipe 19. Under the action of the conveying pump 18, the sludge and water inside the slag hopper 605 can be conveyed to the inside of the ring pipe 19 and then flow through the ring pipe 19.

[0023] The bottom of the ring pipe 19 is connected to an outlet pipe 35, which is multiple in number and has a 45° bevel at the outlet, connecting tangentially to the side wall of the settling tank. This guides the muddy water to enter along the tangential of the tank wall, forming a stable vortex, thus ensuring the water flows along the wall without impact dead zones. A circulating hopper 20 is fixedly connected to the inner wall of the settling tank 701. The circulating hopper 20 is conical, which helps to manage the vortex trajectory, prevent water flow turbulence, and guide large particles to slide down the conical wall to the tank wall. The large particles then slide down the tank wall, and the clear water ring 704... The internal structure is connected by a connecting pipe 21. Under the action of the connecting pipe 21, the clean water inside the central water collection pipe 22 can enter the interior of the clean water ring 704. The end of the connecting pipe 21 away from the clean water ring 704 is connected to the central water collection pipe 22. The central water collection pipe 22 can collect the clean water settled in multiple settling plates 705, so that the clean water passes through multiple water collection holes 23 to reach the connecting pipe 21, and then enters the interior of the clean water ring 704 through multiple connecting pipes 21, thereby facilitating the unified transportation and treatment of the collected clean water by the staff.

[0024] The central water collecting pipe 22 has a water collecting hole 23 inside, and each settling plate 705 has a water collecting hole 23 at its center. The settling plate 705 and the inner wall of the settling bucket 701 have a certain angle, so that clean water can enter the interior of the central water collecting pipe 22 through the water collecting hole 23. A baffle plate 24 is fixedly connected to the top of the settling plate 705. A guide hole 25 is opened inside the settling plate 705. Under the action of multiple guide holes 25, small particles of impurities in the mud and water can enter the interior of the next settling plate 705 through multiple guide holes 25, and clean water gathers inside the settling plate 705. A small amount of clean water enters the interior of the mud hopper 28 along with the small particles of impurities. A connecting cover 26 is fixedly connected to the top of the clean water ring 704, and the bottom of the connecting cover 26... A filter tooth 27 is fixedly connected, which filters and blocks the clean water transported through the connecting pipe 21. A mud collection hopper 28 is connected to the top of the mud outlet pipe 702. A side pipe 29 is connected inside the clean water ring 704, allowing the clean water inside the ring to flow and be transported. A clean water tank 30 is connected to the end of the side pipe 29 away from the ring 704. A positioning cover 31 is fixedly connected to the top of the clean water tank 30, and a dosing pipe 32 is fixedly connected inside the cover 31, allowing for the addition of some chemicals. A stirring mechanism 33 is located at the bottom of the cover 31. A discharge pipe 34 is connected inside the clean water tank 30. The stirring mechanism 33 includes a drive motor, a stirring shaft, and stirring blades, causing the stirring blades to rotate inside the clean water tank 30, ensuring uniform mixing of the clean water and chemicals.

[0025] Working Principle: When processing tunnel boring machine (TBM) slurry, the slurry first enters the pretreatment tank 601 of the pretreatment assembly 6 through the feed pipe 11 on the top plate 10. Simultaneously, the second valve 12 on the outside of the feed pipe 11 controls the start / stop and flow rate of the slurry. The four buffer plates 13 at the bottom of the top plate 10 first block the incoming slurry, significantly reducing its kinetic energy and preventing it from impacting the subsequent filtration structure. The filter screen 603 inside the pretreatment tank 601 performs primary filtration, intercepting larger impurities. The filter cylinder 604 below then performs secondary filtration, capturing smaller medium-sized particles. Impurities are effectively filtered through a dual filtration system to prevent large particles from affecting subsequent settling operations. The filter screen 603 is positioned and installed by engaging the positioning slot 16 on the inner wall of the pretreatment tank 601 with the positioning bracket 14. Rotating the positioning bolt 15 allows it to move in and out of the positioning hole 17, thus completing the installation and removal of the filter screen 603. Simultaneously, the rotating tube 9 at the bottom of the filter screen 603 is threadedly connected to the connecting rod 36 at the top of the filter cylinder 604, ensuring a tight connection and facilitating separate cleaning or replacement. After pretreatment, some of the settled impurities and particles will collect inside the slag hopper 605. Opening the first valve 8 on the outside of the slag discharge pipe 602 allows these... Impurities are discharged into the collection box 4 inside the bottom box 1 through the slag discharge pipe 602, facilitating the unified treatment and collection of impurities inside the slag hopper 605 by the staff. Meanwhile, the sedimented mud and water in the upper part of the slag hopper 605 is drawn by the conveying pump 18 at the top of the bottom box 1 and transported through the connecting pipe 703 to the settling tank 701 of the settling assembly 7. The mud and water first enter the annular pipe 19 on the inner wall of the settling tank 701, and then are discharged through multiple water outlet pipes 35 at the bottom of the annular pipe 19. The outlet of the water outlet pipe 35 has a 45° oblique cut and is tangentially connected to the side wall of the settling tank 701, thus guiding the mud and water along the tangential of the tank wall to form a sedimentation tank. The swirling flow is stabilized, and the conical annular bucket 20 can also regulate the swirling trajectory to prevent water flow turbulence. Large particles of impurities are thrown along the conical wall to the bucket wall and slide down the bucket wall. The mud and water after swirling pre-separation enter the three-layer settling plate 705 inside the settling tank 701. The settling plate 705 is stably fixed by the outer support and forms a certain angle with the inner wall of the settling tank 701. Small particles of impurities in the mud and water enter the lower settling plate 705 through the guide hole 25 on the settling plate 705 to achieve step-by-step settling. Meanwhile, the clean water gathers in each settling plate 705 and flows into the central water collection pipe 22 through the water collection hole 23 at the corresponding position of the central water collection pipe 22.The clean water in the central water collection pipe 22 enters the clean water ring 704 through the connecting pipe 21. The filter teeth 27 below the top connecting cover 26 of the clean water ring 704 will filter and block the clean water again, further improving the water quality. The purified clean water is transported to the clean water tank 30 through the side pipe 29 on the clean water ring 704. The staff can add the chemical through the dosing pipe 32 on the positioning cover 31. With the rotation of the stirring mechanism 33, the chemical and clean water are evenly mixed. The treated clean water is finally discharged through the clean water tank 30. Pipe 34 discharges the sludge for reuse. Meanwhile, the sludge settled in each settling plate 705 is finally collected in the mud hopper 28 at the bottom of the settling tank 701. It is then transported to the plate and frame filter press 5 in the bottom box 1 through the mud discharge pipe 702. The plate and frame filter press in the plate and frame filter press 5 forms a closed filter chamber by the alternating arrangement of filter plates and filter frames. Under the pressure of the hydraulic system, the liquid in the sludge passes through the filter cloth and is discharged. The solid particles are trapped in the filter chamber to form mud cake, thereby achieving the dehydration and solidification of the sludge and completing the entire shield tunnel sludge recycling process.
