Technical Field

[0001] This utility model relates to the field of construction machinery technology, and in particular to an integrated filter press machine for pile foundation mud treatment with automatic flocculant proportioning. Background Technology

[0002] Pile foundation mud is a fluid material used in pile foundation construction, primarily for foundation engineering projects such as bored piles and diaphragm walls. It plays a crucial role in the construction process, and its treatment is also an important aspect of environmental protection and construction management. A filter press, a device that separates solid particles from liquid through pressure, is widely used in pile foundation mud treatment. Pile foundation mud contains a large number of solid particles (such as drill cuttings and soil particles), and filter presses can effectively separate these solid particles from the liquid in the mud, achieving mud volume reduction, harmless treatment, and recycling.

[0003] After research, it was found that existing technologies for pile foundation slurry pressure filtration have problems. While workers add flocculants to the pile foundation slurry to improve dewatering efficiency, in some cases, workers need to manually add the appropriate amount of flocculant. It is difficult to automatically adjust the flocculant dosage based on the flow rate and concentration of the pile foundation slurry, resulting in low efficiency and affecting the treatment of the pile foundation slurry. Therefore, it is necessary to provide a new integrated pile foundation slurry treatment and pressure filtration machine with automatic flocculant proportioning to solve the above-mentioned technical problems.

A pile foundation slurry treatment filter press with automatic flocculant proportioning includes a treatment tank 1. A filter press body 2 for treating pile foundation slurry is installed on one side of the treatment tank 1. The pre-treated pile foundation slurry in the treatment tank 1 is transported to the filter chamber of the filter press body 2. When the pile foundation slurry fills the filter chamber of the filter press body 2, the filter press body 2 applies pressure to the filter plate through a hydraulic system, causing the liquid in the pile foundation slurry to be discharged through the filter cloth, while solid particles are trapped in the filter chamber to form a filter cake, thus completing the treatment of the pile foundation slurry. A flow valve 15 for measuring the flow rate of the pile foundation slurry is fixedly installed on one side of the treatment tank 1, and the flow valve 15 is bolted to one side. There is a feed pipe 14 for feeding materials, and a flow valve 15 can measure the amount of pile foundation mud and calculate the flow rate of pile foundation mud in real time. A flange is fixedly sleeved on the outer circular wall of the feed pipe 14, and an external pipe can be connected to the feed pipe 14 through the flange. A valve 11 is fixedly installed on the other side of the treatment tank 1. A connecting pipe 12 is fixedly sleeved on the inner circular wall of the valve 11. One end of the connecting pipe 12 is connected to the feed pipe of the filter press body 2 through the flange. The timing of the pile foundation mud entering the filter press body 2 inside the treatment tank 1 can be controlled by the valve 11. An automatic proportioning mechanism 6 is set on the outer circular wall of the treatment tank 1 for automatic proportioning of flocculant.

[0022] The automatic proportioning mechanism 6 includes a storage tank 18, which is mounted on the outer circular wall of the treatment tank 1 via a support plate. The storage tank 18 stores a flocculant solution. A metering pump 24, which can be a peristaltic pump or a screw pump, is fixedly installed on one side of the storage tank 18. The metering pump 24 precisely controls the injection volume of the flocculant solution. A support tube 25 is fixedly sleeved on the inner circular wall of the metering pump 24. A support box 16 is fixedly installed on the outer circular wall of the treatment tank 1. The support tube 25 passes through the support box 16 and extends into its interior. A support frame 17 is fixedly installed on one side of the support box 16 and is fixedly connected to the treatment tank 1. A baffle 23 is rotatably connected inside the support box 16 via a rotating shaft. A gear 26 is coaxially connected to one side of the baffle 23 via a rotating shaft. A sector gear 27 is rotatably connected to one side of the support box 16 via a rotating shaft. 7 meshes with gear 26. A connecting frame 28 is fixedly installed on one side of the sector tooth 27. A connecting bracket 29 is slidably connected to the connecting frame 28. A connecting shaft is fixedly installed inside the connecting bracket 29. The connecting shaft is slidably connected to the connecting frame 28. An electric push rod 30 for driving the connecting bracket 29 to slide is installed on one side of the support box 16. The bottom surface of the telescopic shaft of the electric push rod 30 is fixedly connected to the top surface of the connecting bracket 29. A support cylinder 13 is fixedly installed on the outer circular wall of the treatment tank 1. A mud concentration meter 19 for detecting the mud concentration of the pile foundation is fixedly installed on the bottom surface of the support cylinder 13. The detection rod of the mud concentration meter 19 passes through the support cylinder 13 and extends into the interior of the treatment tank 1. A PLC controller is fixedly installed on one side of the storage box 18. The valve 11, electric push rod 30, liquid level sensor 20, metering pump 24 and mud concentration meter 19 are all electrically connected to the PLC controller.

[0023] The internal density of the pile foundation mud inside the treatment tank 1 is detected by mud concentration meter 19, and the flow rate of the pile foundation mud entering the treatment tank 1 is detected by flow valve 15. Then, the PLC controller calculates the required flocculant volume according to the formula, i.e., Q_drug = C_mud x Q_mud x R_drug / C_drug.

[0024] Wherein, Cmud: mud concentration (kg / m3); Qmud: mud flow rate (m3 / h); R: preset dosing ratio (e.g., 0.2%); Cchemical: flocculant solution concentration (e.g., 0.1%).

[0025] After calculation, the corresponding flocculant is delivered to the outside through metering pump 24 and then enters the interior of treatment tank 1 through support pipe 25.

[0026] In the above method, the pile foundation mud enters the treatment tank 1 through the feed pipe 14 and the flow valve 15. The flow valve 15 can measure the amount of pile foundation mud. After the pile foundation mud enters the treatment tank 1, the mud concentration meter 19 on the support cylinder 13 can detect the concentration of the pile foundation mud. The flow valve 15 and the mud concentration meter 19 transmit information to the PLC controller. The PLC controller calculates the amount of flocculant required in the treatment tank 1 using a formula. The PLC controller starts the electric push rod 30. The telescopic axis of the electric push rod 30 moves upward, causing the connecting frame 29 to move upward. The connecting frame 29 moves upward along the connecting frame 28, causing the sector tooth 27 to rotate. The rotation of the sector tooth 27 drives the gear 26 to rotate. The gear 26 rotates... The motor drives the baffle 23 inside the support box 16 to rotate downwards. At the same time, the PLC controller starts the metering pump 24, which delivers the corresponding amount of flocculant solution to the support pipe 25 and into the pile foundation mud inside the treatment tank 1. Then, the PLC controller starts the electric push rod 30. The telescopic axis of the electric push rod 30 moves downwards to reset, allowing the sector tooth 27 and gear 26 to cooperate in driving the baffle 23 to reset. At this time, the baffle 23 can continue to block the opening of the support box 16, preventing the pile foundation mud from entering the interior of the support box 16 and blocking the support pipe 25. This facilitates the subsequent addition of flocculant, thereby automatically proportioning the flocculant required for the pile foundation mud, achieving the effect of automatic proportioning of the pile foundation mud flocculant, and facilitating the subsequent treatment of the pile foundation mud using the filter press body 2.

[0027] The treatment tank 1 is rotatably connected to an auger 8. A drive motor 7 for driving the auger 8 to rotate is installed on one side of the treatment tank 1. One end of the drive shaft of the drive motor 7 passes through the treatment tank 1 and is fixedly connected to one end of the auger 8. The drive motor 7 is electrically connected to a PLC controller. By driving the auger 8 to rotate through the drive motor 7, the pile foundation mud and flocculant can be mixed by the rotation of the auger 8.

[0028] In this method, after the flocculant enters the treatment tank 1 via the drive motor 7, the drive shaft of the drive motor 7 rotates, driving the auger 8 to rotate. The rotation of the auger 8 mixes the flocculant with the pile foundation mud. After the mixing is completed, the PLC controller opens the valve 11, and the auger 8 continues to rotate, allowing the pile foundation mud to enter the filter press body 2 through the valve 11 and the connecting pipe 12. Thus, the pile foundation mud is pretreated using the flocculant, achieving the pretreatment effect of the pile foundation mud.

[0029] The processing tank 1 is equipped with a support ring 10 inside, which is rotatably connected to the auger 8. Two support columns 9 are fixedly installed on the outer circular wall of the support ring 10. One end of the support column 9 is fixedly connected to the inner circular wall of the processing tank 1. The rotation of the auger 8 can be supported by the support column 9 and the support ring 10.

[0030] In this method, the two support columns 9 can support the support ring 10. The auger 8 will rotate inside the support ring 10. The support columns 9 and the support ring 10 work together to support the rotation of the auger 8 and prevent the auger 8 from shaking when it rotates.

[0031] A liquid level sensor 20 for detecting liquid level is fixedly installed on the top surface of the storage tank 18. The measuring rod of the liquid level sensor 20 passes through the storage tank 18 and extends into the interior of the storage tank 18. The liquid level sensor 20 can measure the liquid level of flocculant inside the storage tank 18. A pump body 21 is fixedly installed on one side of the storage tank 18. A hose 22 is fixedly sleeved on the inner circular wall of the pump body 21 inlet. The flocculant solution can be added to the storage tank 18 by the cooperation of the pump body 21 and the hose 22.

[0032] In this method, the operator inserts the hose 22 into the storage tank containing the flocculant solution. The level sensor 20 can detect the level of the flocculant solution inside the storage tank 18. When the level sensor 20 detects that the level of the flocculant solution inside the storage tank 18 is lower than the threshold set by the operator, the PLC controller starts the pump 21. The pump 21 pumps the flocculant solution into the storage tank 18 through the hose 22, thereby automatically replenishing the flocculant inside the storage tank 18.

[0033] Several support legs 3 are fixedly installed on the outer circular wall of the treatment tank 1. Support bases 4 are fixedly installed on the bottom surface of two support legs 3. Several circular holes are opened on the top surface of the support base 4. The position of the treatment tank 1 can be fixed by inserting two bolts into the circular holes on the support base 4. A connecting beam 5 is fixedly installed between every two support legs 3.

[0034] In this method, multiple support legs 3 can support the processing tank 1, and the connecting beam 5 can reinforce the support legs 3, further improving the stability of the processing tank 1.

[0035] The working principle of the integrated pile foundation mud treatment filter press with automatic flocculant proportioning provided by this utility model is as follows: The pile foundation mud enters the treatment tank 1 through the feed pipe 14. The flow valve 15 measures the flow rate of the incoming pile foundation mud in real time and transmits the flow data to the PLC controller. The mud concentration meter 19 detects the concentration of the pile foundation mud inside the treatment tank 1 and transmits the concentration data to the PLC controller.

[0036] The PLC controller calculates the required volume of flocculant according to the corresponding formula. After the calculation is completed, the PLC controller starts the metering pump 24 to deliver the corresponding amount of flocculant solution to the inside of the treatment tank 1 through the support pipe 25.

[0037] At the same time, the PLC controller starts the electric push rod 30, whose telescopic axis moves upward, driving the connecting frame 29 to move upward, causing the sector tooth 27 to rotate, which in turn drives the gear 26 to rotate. The rotation of the gear 26 causes the baffle 23 inside the support box 16 to rotate downward, opening the channel of the support tube 25, allowing the flocculant solution to smoothly enter the treatment tank 1.

[0038] Next, after the flocculant solution is delivered, the PLC controller controls the telescopic shaft of the electric push rod 30 to move downward and reset. The sector tooth 27 and gear 26 cooperate to drive the baffle 23 to reset. The baffle 23 then blocks the opening of the support box 16 again to prevent the pile foundation mud from entering the support box 16 and blocking the support pipe 25.

[0039] In addition, the drive motor 7 starts, and its drive shaft drives the auger 8 to rotate. The auger 8 rotates inside the treatment tank 1, which fully mixes the pile foundation mud and flocculant to complete the pretreatment.

[0040] After mixing, the PLC controller opens valve 11, and the auger 8 continues to rotate, transporting the pretreated pile foundation slurry to the filter chamber of the filter press body 2 through the connecting pipe 12. When the pile foundation slurry fills the filter chamber of the filter press body 2, the filter press body 2 applies pressure to the filter plate through the hydraulic system, causing the liquid in the pile foundation slurry to be discharged through the filter cloth, while the solid particles are trapped in the filter chamber to form a filter cake, thus completing the treatment of the pile foundation slurry.

[0041] Finally, the level sensor 20 detects the level of flocculant inside the storage tank 18 in real time. When the level is lower than the set threshold, the PLC controller starts the pump 21 and draws flocculant solution from the external storage tank through the hose 22 to replenish the storage tank 18.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
