Description

Technical Field

[0001] The utility model relates to the technical field of mud treatment, in particular to a device for quickly preparing fluidized filler based on high-water-content mud. Background Art

[0002] Many engineering projects, such as tunneling, river dredging, foundation treatment, and underground infrastructure construction, generate large quantities of high-water content mud. These muds are typically composed of water, fine particles (such as silt and clay), organic matter, and other impurities, with a water content often exceeding 200%. Due to their high water content, muds exhibit high fluidity and instability, presenting several key challenges in their application. First, high-water content muds are bulky, heavy, and highly fluid, making transportation expensive, especially in urban areas or at construction sites far from treatment plants. Second, because they contain large amounts of water and fine particles, high-water content muds cannot be used directly for backfill or as construction materials. They must be treated to reduce their water content and increase their stability and strength. Traditional solid waste treatment technologies struggle to effectively handle these processes, often requiring multiple, time-consuming, and inefficient dehydration and drying steps. Furthermore, untreated muds may contain contaminants, which, if discharged directly, can easily contaminate surrounding soil and water, causing environmental pollution.

[0003] Fluidized fillers are highly fluid, easily pumpable, and rapidly hardening engineering materials, widely used in foundation reinforcement, backfill projects, tunnel lining, and other fields. Their preparation typically requires a slurry with a low water content and a high solids content to ensure a stable structure upon application and achieve the required strength within a short period of time. To meet the engineering demand for fluidized fillers, technology and equipment are needed that can rapidly process high-water-content slurries on-site and convert them into fluidized fillers.

[0004] The current technologies and equipment for processing high-water content mud mainly include the following, but each has its own shortcomings:

[0005] 1) Natural drying: Spread the slurry on open ground and let it evaporate naturally. This method is extremely inefficient, requires a lot of time and land, and is greatly affected by weather conditions, making it difficult to achieve rapid processing.

[0006] 2) Filtration and filter pressing: Mechanical filter pressing equipment is used to squeeze out water from the mud to produce a solid mud cake. However, this method has high equipment costs, limited processing capacity, and cannot meet the requirements of continuous operation.

[0007] 3) Thermal drying: Using high temperature to evaporate the water in the mud is suitable for mud with low water content, but the energy consumption for mud with high water content is extremely high, which is uneconomical and environmentally unfriendly.

[0008] 4) Chemical curing: By adding chemical curing agents to reduce the moisture content of the mud, although it can effectively solidify the mud to a certain extent, the processing speed is slow and a large amount of chemical agents are consumed, which is costly.

[0009] In practical applications, the above methods are usually difficult to simultaneously meet multiple requirements such as speed, efficiency, environmental protection, and economy. Therefore, there is an urgent need for a device that can efficiently and environmentally treat high-water content mud and convert it into fluid filler.

[0010] The existing patented technology "A production device and production method for preparing fluidized filler using silt soil" (application number CN202311761152.9) has the following defects when preparing fluidized filler:

[0011] 1) Low processing efficiency: This equipment requires the addition of water to the muddy soil and the addition of a solidifying agent to form a fluidized filler. The entire process takes a long time to stir and solidify, so the processing speed is not as fast as the rapid preparation equipment for high-water content mud.

[0012] 2) Uneven mixing: Since the original silty soil is prone to agglomeration after adding the curing agent and water, the curing agent and soil are mixed unevenly, affecting the quality and strength of the filler.

[0013] 3) Equipment complexity: The device includes multiple mechanical components, such as a mixing barrel, a mixing spindle, an air compressor, etc., with many operating steps. Manual monitoring and adjustment of various parameters are required, which increases the complexity of operation and the difficulty of maintenance.

[0014] 4) Limitations: This equipment is mainly used for treating muddy soil in coastal areas or similar geological conditions. Its application range is relatively narrow and it is difficult to deal with other types of high-water content mud. Utility Model Content

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0031] This utility model provides a rapid preparation device for high-water-content mud-based fluidized fillers. This device aims to efficiently and environmentally transform high-water-content mud into fluidized fillers, suitable for a variety of scenarios, including municipal engineering, road construction, and river management. The device integrates functions such as mud transportation, flocculation and solidification agent addition, mud dehydration, and automated control. Mounted on a mobile axle 17, it enables rapid on-site deployment and operation.

[0032] Specifically, such as Figure 1 As shown, a rapid preparation device for fluid filler based on high-water content mud includes a horizontal screw centrifuge 6, a mud pump 2, a flow meter 7, a nozzle 3, a dosing mechanism, a mud conveying pipeline 4, a drug conveying pipeline 5, and a PLC controller 1. The horizontal screw centrifuge 6 is provided with a feed inlet 61, a water filter port 62, and a liquid filler outlet 63. The two ends of the mud conveying pipeline 4 are respectively connected to the mud pump 2 and the feed inlet 61 of the horizontal screw centrifuge 6. The two ends of the drug conveying pipeline 5 are respectively connected to the dosing mechanism and the inlet of the nozzle 3. The outlet of the nozzle 3 is connected to the mud conveying pipeline 4. The mud conveying pipeline 4 and the drug conveying pipeline 5 are both connected to the flow meter 7. The PLC controller 1 is connected to and controls the horizontal screw centrifuge 6, the mud pump 2, and the dosing mechanism. The flow meter 7 is connected to the PLC controller 1 to feedback signals.

[0033] This device utilizes a highly wear- and corrosion-resistant mud pump 2 to extract high-water-content mud from a mud or raw material pool and deliver it to a decanter centrifuge 6 via a mud delivery pipeline 4. The mud pump 2 features adjustable delivery capacity to accommodate varying mud concentrations and flow rates. The mud delivery pipeline 4, constructed of corrosion-resistant piping, connects the mud pump 2 to the decanter centrifuge 6. A flowmeter 7 and a sight glass 16 are installed within the pipeline for real-time monitoring of mud flow and status. The reagent delivery pipeline 5 is directly connected to a nozzle 3 within the mud delivery pipeline 4, ensuring even distribution of the reagent throughout the mud flow.

[0034] After mixing with the reagent, the slurry enters decanter centrifuge 6, where the centrifugal force generated by high-speed rotation removes water from the slurry, reducing its moisture content and forming a fluidized filler that meets the requirements. The speed of decanter centrifuge 6 is automatically adjusted by PLC controller 1 to achieve precise control of the moisture content of the fluidized filler to meet different project requirements.

[0035] PLC Controller 1 automatically controls the entire system, monitoring and adjusting the slurry flow rate, flocculation and solidification agent dosage, and centrifuge speed in real time. Using sensor data, PLC Controller 1 automatically adjusts operating parameters to ensure final product quality and production efficiency.

[0036] The dosing mechanism includes a medicine box 8, a dosing pump 9, a stirring motor 10, and a stirring rod 19. The medicine box 8 is provided with a dosing port 11 for adding a flocculant-curing agent. The dosing pump 9 is connected to the outlet of the medicine box 8. The dosing pump 9 is connected to the medicine delivery pipeline 5. The stirring rod 19 is inserted into the medicine box 8. The stirring motor 10 is connected to the stirring rod 19. The PLC controller 1 is connected to and controls the dosing pump 9 and the stirring motor 10.

[0037] A precision dosing pump 9 injects the flocculating and solidifying agent from the tank 8 into the mud flow through the agent delivery pipe 5. The output of the dosing pump 9 is adjustable to ensure thorough mixing of the agent and the mud. A stirring motor 10 stirs the agent in the tank 8, ensuring a thorough and uniform mixing of the flocculating and solidifying agent.

[0038] The rapid preparation device for a fluidized filler material based on high-water-content slurry also includes a dosing control valve 12, which is installed on the reagent delivery pipeline 5 and located at the outlet of the dosing pump 9. The PLC controller 1 is connected to and controls the dosing control valve 12. Based on information fed back by the flowmeter 7, the PLC controller 1, through the dosing control valve 12, can adjust the flow rate of the flocculating-solidifying agent entering the reagent delivery pipeline 5, thereby adjusting the ratio of the slurry to the flocculating-solidifying agent.

[0039] The rapid preparation device of fluid filler based on high water content mud also includes a one-way valve 13, which is installed on the agent delivery pipeline 5. The one-way valve 13 can prevent the backflow of fluid and prevent the mud from flowing back to the agent tank 8, thereby contaminating the flocculation-solidification agent.

[0040] The rapid preparation device for a fluidized filler material based on high-water-content mud also includes a mud control valve 14, which is installed on the mud delivery pipeline 4 and located at the outlet of the mud pump 2. The PLC controller 1 is connected to and controls the mud control valve 14. Based on information fed back by the flowmeter 7, the PLC controller 1, through the mud control valve 14, can adjust the flow rate of mud entering the mud delivery pipeline 4, thereby adjusting the ratio of mud to the flocculating-solidifying agent.

[0041] The apparatus for rapidly preparing a fluidized filler material based on high-water-content slurry further includes a main valve 15 mounted on the slurry delivery pipeline 4. The main valve 15 controls the flow of fluid from the slurry delivery pipeline 4 into the decanter centrifuge 6 and also controls the opening and closing of the slurry delivery pipeline 4, thereby meeting operational requirements for the slurry delivery pipeline 4.

[0042] The rapid preparation device for fluidized filler based on high-water-content slurry also includes a visual mirror 16, which is installed on the slurry delivery pipe 4 connected to the outlet of the nozzle 3. Through the visual mirror 16, the operator can monitor the mixing effect of the slurry and the reagent in real time, ensuring the stability and efficiency of the production process.

[0043] The nozzle 3 includes an inlet nozzle body 31, an outlet nozzle body 32, and an adjustment knob 33. The inlet nozzle body 31 interfaces with the reagent delivery pipe 5, while the outlet nozzle body 32 interfaces with the slurry delivery pipe 4. A spray hole 34 is provided on the outlet nozzle body 32. The inlet nozzle body 31 and the outlet nozzle body 32 are movably connected. The adjustment knob 33 is connected to the outlet nozzle body 32 and is rotated to adjust the spray angle of the spray hole 34. The inlet nozzle body 31 and the outlet nozzle body 32 can be connected by a threaded connection, and the threaded connection can be equipped with a waterproof sealing ring 35. By rotating the adjustment knob 33, the threaded connection structure can rotate the outlet nozzle body 32 relative to the inlet nozzle body 31 to adjust the angle of the spray hole 34.

[0044] Nozzle 3 is installed in the slurry pipeline, near the inlet of decanter centrifuge 6 (approximately 0.5 to 1 meter). Nozzle 3 features a multi-hole design, and the spray angle is adjustable using knob 33 to ensure thorough mixing of the flocculating-solidifying agent and the slurry. Nozzle 3 is made of corrosion-resistant stainless steel or a high-strength alloy and is sealed.

[0045] The nozzle 3 also includes a waterproof rubber ring 35, which is connected to the joint between the inlet nozzle body 31 and the drug delivery pipe 5. The inlet nozzle body 31 is provided with a thread 36, which connects the inlet nozzle body 31 to the drug delivery pipe 5 through the thread 36. The waterproof rubber ring 35 is installed at the connection between the thread 36 to prevent drug leakage, thereby achieving a leak-proof effect.

[0046] The rapid preparation device for fluidized filler materials based on high-water-content slurry also includes a mobile axle 17, on which are mounted a decanter centrifuge 6, a slurry pump 2, a dosing mechanism, a slurry delivery pipeline 4, a reagent delivery pipeline 5, and a PLC controller 1. The entire device is mounted on the mobile axle 17, which is equipped with hydraulic outriggers 18, enabling rapid deployment and stable operation at various construction sites. This reduces the time and distance of slurry transportation, thereby improving construction efficiency.

[0047] The working process of the rapid preparation device of fluidized filler based on high water content mud is as follows:

[0048] 1) Mud transportation: The mud pump 2 extracts high-water content mud from the mud pool and transports it to the decanter centrifuge 6 through the mud transportation pipeline 4. During the transportation process, the mud flow is monitored in real time by the flow meter 7 in the pipeline to ensure the stability of the transportation process.

[0049] 2) Chemical Injection and Mixing: Dosing pump 9 delivers the flocculating-solidifying agent through chemical delivery pipeline 5 to nozzle 3 in mud delivery pipeline 4. Nozzle 3 sprays the agent evenly into the flowing mud, agglomerating fine particles into larger ones, reducing the fluidity and free water content of the mud while increasing its strength, achieving initial mixing of the agent and mud. Nozzle 3's multi-hole design and adjustable spray angle ensure uniform mixing.

[0050] 3) Centrifugal Dehydration: After mixing with the reagents, the slurry enters the decanter centrifuge 6, where the centrifugal force generated by high-speed rotation rapidly separates the water from the mud. Compared to traditional filtration and filter pressing technologies, centrifugal dehydration can more quickly reduce the water content of the mud, has a large processing capacity, and is suitable for continuous operation. This significantly improves the speed and efficiency of mud processing, enabling high-water content mud to be converted into a fluid filler in a short period of time. The larger particles of flocculated and solidified mud facilitate efficient separation during centrifugal dehydration, which further reduces the water content of the mud, meeting the quality requirements of a fluid filler.

[0051] 4) Product Output: The dehydrated slurry becomes a fluidized filler, which is discharged from the liquid filler outlet 63 of the decanter centrifuge 6 and can be directly used in engineering projects. For projects such as cave filling, this equipment can produce a fluidized filler with a moisture content of 60-80%. For projects such as foundation reinforcement and backfilling, the device can produce a fluidized filler with a moisture content of 40-60%. The dehydrated water is discharged from the water filter outlet 62 of the decanter centrifuge 6 and recycled or further processed through pipelines, minimizing environmental impact.

[0052] 5) Automated Control and Monitoring: PLC controller 1 automatically controls and monitors the entire process, adjusting the flow rates of slurry and reagents, as well as the centrifuge speed, in real time. The use of a visual mirror 16 and flow meter 7 ensures process visualization and controllability.

[0053] 6) Mobile Platform: The device is mounted on a high-load-bearing and stable mobile axle 17 and equipped with hydraulic outriggers 18, ensuring stable operation on diverse terrains. The device can be moved on-site as construction progresses, making it particularly suitable for projects requiring continuous operation at multiple locations, such as tunneling and river dredging. Because the device can be deployed at the construction site at any time, mud does not need to be transported long distances, reducing transportation costs and time, and reducing the complexity and cost of secondary mud processing.

[0054] The following describes the practical application of the device in detail with reference to two embodiments.

[0055] Example 1: Treatment of high-water content slurry in municipal drainage projects

[0056] Municipal drainage projects often require the removal of sludge from drainage pipes and sewage treatment facilities. This sludge often contains a high water content, making direct transportation and disposal not only costly but also environmentally harmful. To improve efficiency and reduce transportation costs, on-site processing of this high-water content sludge and preparing it into a fluidized filler material is a highly effective solution.

[0057] Application Process:

[0058] 1) On-site Deployment: The device is mounted on a mobile axle 17 and transported directly to the municipal drainage project construction site. The hydraulic legs 18 of the mobile axle 17 provide stable positioning, ensuring safe operation on uneven surfaces.

[0059] 2) Mud Extraction: High-water-content mud is extracted from drainage pipes and sewage treatment tanks. Mud pump 2 delivers this mud through mud delivery pipeline 4 to the inlet of the decanter centrifuge 6 of the device. The mud flow rate and moisture content are monitored in real time in the pipeline using flow meter 7 and sensors.

[0060] 3) Adding and mixing flocculating-solidifying agent: The dosing pump 9 injects the flocculating-solidifying agent into the nozzle 3 in the mud conveying pipeline 4, and the agent is evenly sprayed into the mud flow through the nozzle 3. Before entering the decanter centrifuge 6, the mud and agent are initially mixed in the pipeline.

[0061] 4) Centrifugal Dehydration: The mixed slurry enters the decanter centrifuge 6 for high-speed centrifugal dehydration. The PLC controller 1 adjusts the centrifuge speed to ensure that the moisture content of the dehydrated slurry meets the requirements of municipal filler.

[0062] 5) Application of Fluid Fill: Dewatered slurry becomes fluid fill, which can be used to backfill gaps around drainage pipes or as a foundation material in road construction. On-site processing not only saves on slurry transportation and handling costs, but also avoids the environmental impact of transporting large quantities of water-containing slurry to distant landfills.

[0063] Effects and advantages:

[0064] Because slurry treatment is completed on-site, transportation and external handling costs are significantly reduced. Direct construction using fluidized fill reduces construction time. Treated water is recycled, reducing wastewater discharge and meeting environmental standards. The equipment is easily portable and adaptable to different construction locations and environments.

[0065] Example 2: Treatment of high-water content slurry generated by shield tunneling

[0066] During shield tunneling, large quantities of high-water content slurry are generated. This slurry has an extremely high water content, is highly fluid, and is unstable. If not promptly processed, it will incur high transportation and disposal costs and may pollute the surrounding environment. By using a rapid fluidized filler preparation device for high-water content slurry, the slurry can be processed on-site at the shield construction site, converted into a fluidized filler that meets engineering requirements for use in tunnel backfill and reinforcement.

[0067] Application Process:

[0068] 1) Device Deployment: The device is mounted on a mobile axle 17 and can be flexibly moved to follow the progress of the shield machine. Because large quantities of slurry are generated continuously during shield tunneling, the device can be quickly deployed at the shield construction site, reducing the need for long-distance transportation of slurry.

[0069] 2) Slurry Delivery: The high-water content sludge generated during shield tunneling is delivered to the device via slurry pump 2. Since the slurry typically has a high water content, a flocculating and solidifying agent must first be injected into the slurry delivery pipeline 4 via a dosing pump 9.

[0070] 3) Flocculant mixing and dehydration: Nozzle 3 evenly sprays the flocculant-solidifying agent into the mud. The sprayed mud is then transported through a pipeline and enters a decanter centrifuge 6. The decanter centrifuge 6 rapidly removes moisture from the mud through high-speed rotation, generating a fluidized filler with a low water content.

[0071] 4) Application of Fluidized Filler: Dehydrated fluidized filler can be directly used for backfilling shield tunnels, filling gaps inside and outside tunnels, and ground reinforcement. Based on project requirements, the equipment can adjust the speed of the decanter centrifuge 6 to produce filler with different moisture contents to suit different stages of tunnel construction.

[0072] 5) Automated Control and Environmental Protection: The device's PLC controller 1 automatically adjusts various mud processing parameters to ensure efficient and safe processing. Furthermore, the water generated during the dehydration process is collected and processed for reuse, reducing pollution to the surrounding environment and water waste.

[0073] Effects and advantages:

[0074] By processing high-water-content slurry directly at the shield construction site, the device significantly reduces transportation costs and time for slurry handling. Furthermore, by converting slurry into a fluidized filler, the shield construction team can better control tunnel quality, particularly in areas such as foundation reinforcement and gap filling. Furthermore, the device's mobility and automated control improve construction efficiency and ensure smooth project progress. Its mobile design allows for rapid deployment and operation at a variety of construction sites, enhancing construction flexibility.

[0075] The utility model has the following advantages for the rapid preparation device of fluidized filler based on high-water content mud:

[0076] 1) Combination of flocculation and solidification with centrifugal dehydration: Combining flocculation and solidification technology with centrifugal dehydration technology can significantly reduce the water content of the mud in a short period of time. At the same time, the strength of the fluidized filler after centrifugal dehydration can be increased, thereby improving treatment efficiency.

[0077] 2) Strong mobility and site adaptability: The device is installed on a mobile axle 17 and can be quickly deployed and used at different construction sites, adapting to various complex environments.

[0078] 3) Intelligent control system: The automated control system can monitor and adjust processing parameters in real time to ensure the stability of the fluidized filler quality, reduce human operating errors, and improve safety.

[0079] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
