Description

Technical Field

[0001] This invention relates to the technical field of drilling mud filtration systems for bored piles, and particularly to a drilling mud filtration system for bored piles. Background Technology

[0002] Drilled pile construction is a common method in building construction. However, pile driving generates a large amount of drilling mud, which contains a large amount of impurities such as mud, sand, and rock powder. Direct discharge of this mud would cause serious environmental pollution. Furthermore, mud disposal requires significant time and space, impacting construction progress. Traditional mud treatment methods are inefficient and cannot meet the environmental and efficiency requirements of modern construction. Therefore, the purpose of this invention is to provide a highly efficient drilling mud dewatering system. This system can effectively dewater the mud, remove large particles of slag, and form a filter cake with low moisture content, enabling mud recycling, reducing environmental pollution, and improving construction efficiency.

[0003] Replacing traditional natural sedimentation tanks with multiple automated devices improves construction efficiency: the automated processing system enables rapid recycling of mud, reducing reliance on new mud and increasing construction efficiency; it reduces environmental pollution: by processing the mud, it achieves cleaning and reuse, reducing environmental pollution; it saves costs: the automated processing system reduces mud treatment costs and saves resources during construction; it reduces construction site occupation: the automated processing system reduces the space required for mud disposal, saving construction space; and it improves construction quality: clean mud helps ensure the quality of pile foundation construction and improves the overall quality of the project.

[0033] like Figures 1 to 5 As shown, an embodiment of the present invention provides a drilling mud filtration system for bored piles, including a mud suction component 1, a waste mud storage component 2 connected to the rear end of the mud suction component 1, a slurry purification and separation pretreatment component 3 interspersed in the middle part of the waste mud storage component 2, a stirring component 4 inside the waste mud storage component 2, a mud pumping component 5 connected to the rear end of the waste mud storage component 2, a mud filtration component 6 connected to the rear end of the mud pumping component 5, and a clean water storage component 7 covering the top of the waste mud storage component 2. The entire system, including the mud suction component 1, waste mud storage component 2, slurry purification and separation pretreatment component 3, stirring component 4, mud pumping component 5, mud filtration component 6, and clean water storage component 7, constitutes a high-efficiency mud filtration system. The various devices work closely together to quickly and efficiently process the large amount of waste mud generated during the construction of bored piles. The three slurry purification and separation pretreatment components 3, mud pumping component 5, and mud filtration component 6 do not require waiting for the waste mud to settle naturally over a long period. The system includes a connecting pile hole 101, with a mud suction bend pipe 102 connected inside the connecting pile hole 101. One end of the mud suction bend pipe 102 is connected to a mud suction pump 103. The waste mud storage assembly 2 includes a pre-treatment mud storage tank 201 and a mud purification mud storage tank 202. One-way mud pumps 203 are respectively connected to the bottom edge of one side surface of the two pre-treatment mud storage tanks 201 and the mud purification mud storage tank 202. The clean water storage assembly 7 includes two mud-water filters 701. Each mud... A bottom water pump 702 is connected to the bottom of the water filter 701. A multi-channel water pipe 703 is connected to the top of the two mud and water filters 701. A clean water filter 704 is connected to the end of the multi-channel water pipe 703. A porous hub pipe 705 is connected to the bottom of the clean water filter 704. A filter press conveying mud pump 706 is connected to one end of the porous hub pipe 705. A clean water storage tank 707 is connected to the other end of the porous hub pipe 705. A faucet 708 is provided on one side of the clean water storage tank 707.

[0034] The filter press pump 706, connected to one end of the porous hub pipe 705 within the clear water storage component 7, is a unidirectional output pump. It is connected to the output end of the mud pump assembly 5 and delivers the mud to the filter press assembly 6. Therefore, it will not combine with the clear water at the other end and contaminate the clear water. The clear water storage component 7 can absorb mud and water from multiple mud storage tanks and perform multi-layer filtration, delivering all of it to the clear water storage tank 707 to meet other needs at the construction site.

[0035] By installing the mixing component 4 inside the slurry storage tank 202 after slurry purification, if the slurry inside the slurry storage tank 202 has solidified or become viscous after a period of work interruption, the mixing component 4 can be started to stir and disperse the slurry inside the slurry storage tank 202 to facilitate the resumption of work.

[0036] The automated system consists of the following components: a waste mud storage device, including a pretreatment mud storage tank 201, a mud suction curved pipe 102 connecting the pile hole 101 and the pretreatment mud storage tank 201, and a mud suction pump 103.

The inlet of the mud purifier 305 is connected to a one-way mud pump 203 connected to one side of the pretreatment mud storage tank 201 via a pipe. The mud purifier 305 can separate large particles from the waste mud, and the separated slurry is discharged into the mud purification and treatment system via the slurry pressurized conveyor belt 307. Inside the slurry storage tank 202, large particles of slag are intercepted and removed. The slurry pumping device mainly includes a hydraulic ceramic plunger pump 503. The inlet of the hydraulic ceramic plunger pump 503 is connected to a one-way slurry pump 203 extending into the bottom of the slurry storage tank 202 after slurry purification treatment. The outlet is connected to the inlet of the slurry filter press through a pipeline. The slurry in the slurry storage tank 202 after slurry purification treatment is pressurized and transported to the filter press. The slurry filter press includes a filter press support frame 601, a filter press 604, a mud cake conveying channel 606, and other components. After the slurry enters the filter press chamber of the filter press 604, the driving component pushes the pressing plate, causing the filter press plates to squeeze the slurry against each other. Water is discharged from the drain outlet, and solid waste forms a cake-shaped sludge with low moisture content. The sludge can be discharged from the mud cake conveying channel 606.

[0037] like Figures 6 to 10As shown, the stirring assembly 4 includes a supporting shell 401. A rotary motor 402 is located at the center of the top surface of the supporting shell 401. The output end of the rotary motor 402 is connected to the stirring rod 403. Several stirring blades 404 are arranged on the outer surface of the stirring rod 403. The slurry purification and separation pretreatment assembly 3 includes a workbench support 301. A main power control terminal 302 is located on one side edge of the top surface of the workbench support 301. A mud particle conveying motor 303 is located at the bottom of the workbench support 301. The output end of the mud particle conveying motor 303 is connected to the conveying pipe 304.

The top of the slurry pressurized conveying belt 307 is connected to the mud particle purified conveying pipe 306. The surface is equipped with a mud particle screening device 308, and a slurry pressurized conveyor belt 307 is installed at the center of the top surface of the workbench support 301. The mud pump assembly 5 includes a base 501. A power motor 502 is provided on the left side of the top surface of the base 501. Two hydraulic ceramic plunger pumps 503 are arranged in a row on the right side of the top surface of the base 501. The output ends of the two hydraulic ceramic plunger pumps 503 are provided with slurry outlets 504. The mud filter press assembly 6 includes a filter press support frame 601. A filter press box 602 is provided on the left side of the top surface of the filter press support frame 601. A slurry inlet 603 is opened on the left side of the filter press box 602. A filter press device 604 is provided inside the filter press box 602. A mud cake outlet 605 is provided on the right side of the filter press box 602. A mud cake conveying channel 606 is provided at the bottom of the mud cake outlet 605. The mud cake outlet 605 is connected to the filter press device 604.

[0038] like Figures 1 to 10As shown, the advantages of the automated system are: efficient dewatering and filter cake formation: through the squeezing action of the filter plates in the mud filter press, the water in the mud can be squeezed out quickly and effectively, forming a filter cake with low moisture content. Compared with traditional methods such as natural sedimentation, this greatly shortens the processing time and improves dewatering efficiency. Large particle removal: the mud purifier in the slurry purification and separation pretreatment device can effectively remove large particles of slag from the mud, preventing them from entering the subsequent filter press, preventing equipment blockage, ensuring stable system operation, and also improving the quality of the filter cake. Mud recycling: the filtrate discharged during the filter press is basically clear water, which can be recycled for on-site construction, such as as circulating mud water for drilling or for washing equipment, realizing the recycling of mud, saving water resources and slurry materials, reducing construction costs, and reducing environmental pollution. This system enables on-site treatment of drilling mud, avoiding the indiscriminate dumping that can occur with traditional mud truck disposal methods, thus reducing pollution to the surrounding environment. Simultaneously, the filter cake formed by pressure filtration can be transported to a processing plant for reuse, such as being pressed into environmentally friendly bricks, further reducing waste impact on the environment and improving construction efficiency. The system's various components work closely together to quickly and efficiently process large amounts of waste mud generated during bored pile construction. It eliminates the need to wait for prolonged natural sedimentation of the waste mud, allowing for immediate processing, significantly improving construction efficiency, reducing the impact of mud treatment on project progress, and addressing the shortcomings of existing mud treatment equipment, such as small processing capacity, complex structure, inconvenient operation, low automation, and high moisture content in the treated mud cake. These shortcomings prevent the system from meeting the needs of rapid and effective mud treatment in large-scale bored pile projects.

The slurry purification and separation pretreatment device mainly consists of a mud purifier 305 and a slurry pressurized conveyor belt 307. The inlet of the mud purifier 305 is connected to a one-way mud pump 203 connected to one side of the pretreatment storage tank 201 via a pipe. The mud purifier 305 can separate large particles from the waste mud, and the separated slurry is discharged into the mud purification treatment system via the slurry pressurized conveyor belt 307. In the post-slurry storage tank 202, large particles of slag are intercepted and removed. The slurry pumping device mainly includes a hydraulic ceramic plunger pump 503. The inlet of the hydraulic ceramic plunger pump 503 is connected to a one-way slurry pump 203 extending into the bottom of the slurry storage tank 202 after slurry purification treatment. The outlet is connected to the inlet of the slurry filter press through a pipeline.

The slurry filter press is equipped with a filter press support frame 601, a filter press 604, a mud cake conveying channel 606, and other components. After the slurry enters the filter press chamber of the filter press 604, the driving component pushes the pressing plate, causing the filter press plates to squeeze the slurry against each other. Water is discharged from the drain outlet, and solid waste forms a cake-shaped sludge with low moisture content. The sludge can be discharged from the mud cake conveying channel 606.
