Description

Technical Field

[0001] The present invention relates to the technical field of mud recovery, and particularly to a cast-in-place pile mud recovery device. Background Art

[0002] Cast-in-place pile construction is widely used in foundation engineering to support the loads of buildings and other structures. The cast-in-place pile construction process includes drilling, placing the steel cage, and pouring concrete. This process generates a large amount of mixture, namely cast-in-place pile mud, which is mainly composed of water, soil, and additives (such as bentonite). Cast-in-place pile mud recovery is a crucial process aimed at reducing mud waste during construction, reducing environmental pollution, and saving construction costs. Cast-in-place pile mud recovery mainly involves treating and reusing the mud generated during the construction process.

[0003] In the traditional cast-in-place pile mud recovery process, the mud recovery method usually relies on a vibrating screen for water filtration separation. However, due to the limited vibration frequency and intensity of the vibrating screen, the structure of the mud cannot be completely destroyed, resulting in insufficient release of water. Although large particle impurities in the mud can be screened out by the vibrating screen, fine particles and suspended substances are difficult to effectively separate in this way. The water filtration effect during recovery is poor, and the water in the mud cannot be completely filtered out, resulting in a high water content in the recovered mud cake and a loose texture. Such mud cakes with a high water content are extremely prone to breaking and dispersing during subsequent treatment and transportation, not only increasing the treatment difficulty but also potentially causing secondary pollution. Moreover, due to the insufficient dryness of the soil, these mud cakes are prone to deformation and disintegration during storage and reuse, affecting their reuse effect and stability. Summary of the Invention

[0004] The present invention provides a cast-in-place pile mud recovery device, which solves the technical problems that in the traditional cast-in-place pile mud recovery, only relying on the water filtration separation method of vibrating the vibrating screen cannot completely destroy the mud structure, resulting in insufficient release of water, poor water filtration effect, high water content in the mud cake, loose texture, and insufficient dryness of the mud cake.

[0007] In a possible implementation manner, a through groove is opened on the outer wall of the sector-shaped separation frame. An arc-shaped net plate is hinged to the upper groove wall of the through groove through a lug. A retaining ring for limiting the arc-shaped net plate is fixedly connected to the inner wall of the water collecting cylinder through a fixing column. A number of top contact plates abutting against the outer wall of the arc-shaped net plate are equidistantly slidably connected to the circumferential inner wall of the water collecting cylinder through spring telescopic columns.

[0008] In a possible implementation manner, the upper surface of the guide ring gradually inclines away from the axis side of the shaft rod from top to bottom, and a number of slicing pieces are fixedly connected to the upper surface of the guide ring circumferentially and equidistantly.

[0009] In a possible implementation manner, the one-way rotation limiting component includes abutting blocks symmetrically fixedly connected to the circumferential inner wall of the bearing ring, and two first elastic shims symmetrically fixedly connected to the outside of the shaft rods for cooperating with the abutting blocks.

[0010] In a possible implementation, the pressing component includes an L-shaped plate fixedly connected to the upper end surface of the processing table. A reciprocating wire cylinder is rotatably connected to the lower end surface of the horizontal section of the L-shaped plate. The lower end surface of the horizontal section of the L-shaped plate is slidably connected to a connecting telescopic column, and a ring frame sleeved outside the reciprocating wire cylinder is provided. A sliding tongue slidably matched with the reciprocating wire cylinder is hinged to the inner wall of the ring frame.

[0013] From the above technical solutions, it can be seen that the present invention has the following advantages:

[0014] In the present invention, through a water filtration and separation method combining centrifugal water filtration and vertical pressure filtration, the centrifugal separation uses the centrifugal force generated by high speed rotation, which can more thoroughly break the structure of the slurry, fully release the water, avoiding the poor water filtration effect caused by limited vibration frequency and intensity in the traditional method. It can efficiently remove most of the water in the slurry, including fine particles and suspended substances, effectively separating the mud and water in the slurry. The extrusion water filtration further strengthens the dehydration effect of the slurry, can further remove the residual water, significantly improves the dryness of the mud cake, ensuring that it forms a flat mud cake with a dense texture. Compared with the traditional method, the high-dryness mud cake recovered by the present invention is not easily broken and dispersed during subsequent processing and transportation, thus reducing the processing difficulty and transportation cost and avoiding secondary pollution.

[0015] In the present invention, while the slurry of the cast-in-place pile is pressure-filtered, it is heated and dried, which promotes the rapid evaporation of the residual water in the slurry, speeds up the water filtration and separation speed, further reduces the water content of the mud cake, and greatly shortens the slurry treatment time.

Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 and

[0033] Please refer to Figure 2 andFigure 3 In this embodiment, the driving part 3 includes an incomplete gear disc 31 rotatably connected to the lower end face of the processing table 1 through a driving shaft. A transmission gear 32 meshing with the incomplete gear disc 31 is fixedly connected to the lower end of the shaft rod 2. A torsion spring 33 sleeved outside the shaft rod 2 is fixedly connected between the outer wall of the shaft rod 2 and the lower end face of the processing table 1.

[0034] Please refer to Figure 3 、 Figure 4 、 Figure 7 、 Figure 10 and Figure 11 ,The multi-chamber centrifugal filter press mechanism 4 includes a bearing ring 41 rotatably connected to the outside of the shaft rod 2, a one-way rotation limiting component 42 jointly arranged between the bearing ring 41 and the shaft rod 2, a filter disc 43 fixedly connected to the outside of the bearing ring 41, a plurality of sector-shaped separation frames 44 circumferentially and equidistantly fixedly connected to the upper part of the filter disc 43, a pressing component 45 arranged on the upper part of the shaft rod 2, and a plurality of extrusion plates 46 circumferentially and equidistantly arranged on the pressing component 45 for pressing and filtering the separated slurry. A through groove is formed in the outer wall of the sector-shaped separation frame 44, and an arc-shaped mesh plate 7 is hinged to the upper groove wall of the through groove through a lug. The one-way rotation limiting component 42 includes a stopper 421 symmetrically fixedly connected to the inner wall of the circumference of the bearing ring 41, and two first elastic shifters 422 symmetrically fixedly connected to the outside of the shaft rod 2 for cooperating with the stopper 421.

[0035] Please refer to Figure 4 、 Figure 5 and Figure 12 ,The pressing component 45 includes an L-shaped plate 451 fixedly connected to the upper end face of the processing table 1. A reciprocating wire cylinder 452 is rotatably connected to the lower end face of the horizontal section of the L-shaped plate 451. A ring frame 453 sleeved outside the reciprocating wire cylinder 452 is slidably connected to the lower end face of the horizontal section of the L-shaped plate 451 through a connecting telescopic column. A sliding tongue slidably cooperating with the reciprocating wire cylinder 452 is hinged to the inner wall of the ring frame 453. A plurality of L-shaped columns 454 corresponding to the sector-shaped separation frames 44 are equidistantly fixedly connected to the outer circumference of the ring frame 453. The extrusion plate 46 is fixedly connected to the lower end of the vertical section of the L-shaped column 454. A collar 455 sleeved outside the shaft rod 2 is fixedly connected to the lower part of the reciprocating wire cylinder 452. A plurality of blocks 456 are equidistantly fixedly connected to the inner wall of the circumference of the collar 455. Two second elastic shifters 457 cooperating with the blocks 456 are symmetrically fixedly connected to the outer wall of the shaft rod 2.

[0036] The bored pile slurry is passed into the fan-shaped separation frame 44, and then the self-driven driving shaft is controlled to drive the incomplete gear plate 31 to rotate. When the incomplete gear plate 31 rotates and meshes with the transmission gear 32, it will drive the transmission gear 32 to rotate synchronously. The transmission gear 32 then drives the shaft rod 2 to rotate, and the shaft rod 2 then drives the No. 1 elastic paddle 422 to rotate. The rotation direction of the No. 1 elastic paddle 422 at this time will abut against the stop block 421 and then drive the bearing ring 41 to rotate synchronously. The bearing ring 41 then drives the filter plate 43 and the fan-shaped separation frame 44 to rotate. The centrifugal force generated during the rotation process will throw out the water in the bored pile slurry, and the thrown out water will then pass through the arc mesh plate 7 and be thrown into the water collecting barrel 62. At the same time, the water in the bored pile slurry also passes through the filter plate 43 under its own gravity and enters the water collecting barrel 62, so that the bored pile slurry can be centrifugally dehydrated.

[0037] When the incomplete gear plate 31 rotates to the position where there is no tooth and is relative to the transmission gear 32, the compressed torsion spring 33 is reset and released, driving the shaft rod 2 to rotate in the opposite direction, and then driving the No. 1 elastic paddle 422 to reverse. At this time, the No. 1 paddle is separated from the block 421 and idles, so that the filter plate 43 stops rotating. The reversed shaft rod 2 drives the No. 2 elastic paddle 457 to rotate synchronously. At this time, the rotating No. 2 elastic paddle 457 will abut against the block 456 and drive the collar 455 to rotate synchronously, and the collar 455 then drives As the reciprocating wire drum 452 rotates, the ring frame 453 is driven downward by the sliding tongue during the rotation of the reciprocating wire drum 452, and the ring frame 453 then drives the extrusion plate 46 to gradually move downward through the L-shaped column 454, until the extrusion plate 46 moves downward and slowly extends into the fan-shaped separation frame 44, vertically extruding the cast-in-place pile mud after centrifugal dehydration, further dehydrating the mud to form a flat mud cake, and then the extrusion plate 46 after pressing is driven to gradually move upward and move out of the fan-shaped separation frame 44 under the rotation of the continuously rotating reciprocating wire drum 452.

[0038] See also Figure 5 , Figure 8 , Figure 10 and Figure 11 In this embodiment, the steaming mechanism 5 includes a plurality of pillars 51 which are circumferentially equidistantly fixedly connected to the upper end surface of the processing table 1 and correspond to the fan-shaped separation frame 44. The upper ends of the pillars 51 penetrate the lower wall plate of the water collecting cylinder 62 and are fixedly connected to the arc-shaped bar seat 52. The pillars 51 and the water collecting cylinder 62 are slidably connected to each other. The arc-shaped bar seat 52 is equidistantly connected to a plurality of rotating shafts 53. The end of the rotating shaft 53 away from the shaft 2 is fixedly connected to a heating rod 54. The outside of the heating rod 54 is fixedly connected to a mask 55. The outside of the shaft 2 is fixedly connected to an end face ring 56 that conflicts with the outer wall of the rotating shaft 53 through a connecting rod. The outside of the rotating shaft 53 is fixedly connected to a limiting block 57.

[0039] When the slurry of the cast-in-place pile is introduced into the sector separation frame 44, the mask 55 is located directly above the heating rod 54, which can guide the water falling during the preliminary water filtration separation to block the heating rod 54, preventing most of the water from falling on the heating rod 54. When the centrifugal dehydration of the cast-in-place pile slurry is completed and the shaft rod 2 starts to rotate reversely to drive the extrusion plate 46 to move downward for vertical pressure filtration: the shaft rod 2 will also drive the end face ring 56 to rotate, the rotation of the end face ring 56 drives the rotating shaft 53 to rotate reversely, and the rotating shaft 53 then drives the heating rod 54 to rotate until the heating rod 54 rotates 180 degrees. At this time, the limit block 57 abuts against the end face ring 56 to stop the rotation of the rotating shaft 53, and the friction between the end face ring 56 and the rotating shaft 53 changes from rotational friction to sliding friction. The rotated heating rod 54 is directly below the filter disc 43 area where the sector separation frame 44 is located, heating and drying the cast-in-place pile slurry during pressure filtration to further dehydrate it. (When some of the water dripping during the pressure filtration process of the extrusion plate 46 falls outside the heating rod 54, it will be directly evaporated).

[0040] Please refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9 In this embodiment, the mud and water storage mechanism 6 further includes a guide ring 63 fixedly connected to the upper part of the water collecting cylinder 62. A circular ring 64 is fixedly connected to the circumferential surface of the water collecting cylinder 62 close to the shaft rod 2. A rotating ring 65 is fixedly connected to the inner wall of the circular ring 64, and an interference fit is formed between the rotating ring 65 and the circular ring 64. A spiral groove 66 is formed on the outer wall of the shaft rod 2. A sliding column 67 fixedly connected to the inner wall of the rotating ring 65 is slidably arranged in the spiral groove 66. The upper surface of the guide ring 63 gradually inclines away from the axis side of the shaft rod 2 from top to bottom. A plurality of slicing pieces 11 are fixedly connected to the upper surface of the guide ring 63 at equal circumferential intervals. A retaining ring 8 for limiting the arc-shaped mesh plate 7 is fixedly connected to the inner wall of the water collecting cylinder 62 through a fixing column. A plurality of top contact plates 10 that abut against the outer wall of the arc-shaped mesh plate 7 are equidistantly slidably connected to the circumferential inner wall of the water collecting cylinder 62 through spring telescopic columns 9.

[0041] When the shaft rod 2 is driven to rotate forward, the sliding column 67 is at the upper position of the spiral groove 66. At this time, the water collecting cylinder 62 is at the highest position. The retaining ring 8 abuts against the outside of the arc-shaped mesh plate 7, which can play a role in limiting the arc-shaped mesh plate 7 and prevent the arc-shaped mesh plate 7 from opening during centrifugal dehydration. Then, the spring telescopic column 9 pushes the top contact plate 10 to tightly abut against the outer wall of the arc-shaped mesh plate 7, so that a large frictional resistance needs to be overcome when the filter disc 43 rotates. Using the frictional resistance of the top contact plate 10 pressing against the outer wall of the arc-shaped mesh plate 7, when the shaft rod 2 rotates reversely to drive the extrusion plate 46 to move downward for pressure filtration later, the sector separation frame 44 can remain stationary.

[0042] When the shaft rod 2 starts to rotate in the reverse direction after the slurry separation of the cast-in-place pile slurry is completed: the reverse rotation of the shaft rod 2 drives the spiral groove 66 to gradually change its position, and then the spiral groove 66 squeezes the sliding column 67 to gradually move downward. The sliding column 67 then drives the rotating ring 65 to move downward, and the rotating ring 65 drives the water collecting cylinder 62 to move downward through the circular ring 64. The downward movement of the water collecting cylinder 62 drives the retaining ring 8 and the top contact plate 10 to gradually move downward until the retaining ring 8 and the top contact plate 10 move downward to the dislocation separation position on the arc-shaped mesh plate 7. At this time, the guide ring 63 is driven to move downward to a position flush with the upper end surface of the filter disc 43. After the top contact plate 10 is separated from the arc-shaped mesh plate 7, the frictional resistance that needs to be overcome during the rotation of the filter disc 43 is lost. Then, under the action of the frictional force between the bearing ring 41 and the shaft rod 2, the reversely rotating shaft rod 2 drives the filter disc 43 to rotate synchronously. The centrifugal force generated during the reverse rotation of the filter disc 43 causes the arc-shaped mesh plate 7 to rotate around the lug, and then the mud cake after water filtration is thrown out. The thrown mud cake moves outward along the inclined surface on the upper part of the guide ring 63 and is cut into pieces by the slicing piece 11. The inclined surface on the upper part of the guide ring 63 is used to further enable the thrown and cut mud cake to move outward, so that the mud cake after water filtration can be automatically discharged.

[0043] Finally, after the mud cake is completely discharged, the incomplete end face gear disc meshes with the transmission gear 32 again, and the shaft rod 2 is then driven to rotate forward. At this time, the above operation of introducing the cast-in-place pile slurry into the fan-shaped separation frame 44 is repeated again to filter and recycle the cast-in-place pile slurry again.

[0044] During operation, first, the cast-in-place pile slurry is introduced into the multi-chamber centrifugal pressure filtration mechanism 4, and then the control drive unit 3 is operated to drive the multi-chamber centrifugal pressure filtration mechanism 4 to operate, sequentially centrifugally removing most of the water from the introduced cast-in-place pile slurry and further vertically squeezing and filtering the water. While the cast-in-place pile slurry is vertically pressure-filtered, the drying and steaming mechanism 5 operates synchronously to heat and dry the cast-in-place pile slurry from below to further remove the water in the slurry. The water removed during the water filtration process is collected by the mud and water storage mechanism 6. Finally, the mud cake formed after pressure filtration is also collected by the mud and water storage mechanism 6, and the water and mud during the filtration and separation process of the cast-in-place pile slurry are automatically separated and collected by the mud and water storage mechanism.
