[0001] The invention relates to the technical field of drilling mud treatment, and in particular to a bridge pile foundation excavation mud separation and purification device. Background Art

[0002] During the construction of bridge pile foundations, a large amount of mud and slag mixture is generated, which needs to be excavated and transported. The mud and slag generated during the pile foundation drilling process need to be separated multiple times. The mud is recycled for pile foundation drilling, and the slag is brightly dried and matured before being used for agricultural production, reducing industrial water consumption and mud pollution to water bodies and the environment.

[0003] The mud contains hard mud blocks, gravel, etc., which can easily clog the suction pipe for sucking the mud, making it difficult to circulate or discharge the mud. It is necessary to frequently remove the suction pipe manually or mechanically. At the same time, reverse flushing and other methods are required to clear the mud, which affects the continuity of mud separation and makes clearing inconvenient.

[0008] The extraction and filtering device includes a branch pipe, which is connected to the circular pipe. A filter cartridge is provided at one end of the branch pipe away from the circular pipe. A suction pipe is provided at the bottom of the filter cartridge. The upper end of the suction pipe is hingedly connected to a baffle, and a torsion spring is provided on the hinge shaft of the baffle.

[0012] Preferably, an air pump or an automatic air supply device is provided on the side of the branch pipe.

[0013] Preferably, the automatic air supply device includes two oblique rods, which are fixedly connected to the two ends of the upper side of the temporary storage box respectively, and the upper ends of the two oblique rods are fixedly connected to the cross bar. The side of the branch pipe is fixedly connected to the cylinder barrel, and an air inlet pipe is provided on one side of the cylinder barrel. The air outlet pipe is fixedly connected between the other side of the cylinder barrel and the branch pipe.

[0017] The advantages of the present invention are: a bridge pile foundation excavation mud separation and purification device provided by the present invention is periodically sucked by a water pump. During suction, sewage mixed with gravel flows, and the gravel enters the filter cylinder from the suction pipe and is filtered and blocked by the upper end of the filter cylinder.

The circular column leaves the arc-shaped groove, and further input airflow is formed. The filter cartridge will be pushed away, thereby achieving the above-mentioned effect, thereby facilitating the effect of crushing mud blocks and dredging, and at the same time facilitating the vibration discharge of debris in the filter cartridge.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Example 1

[0025] As shown in Figures 1-4, a bridge pile foundation excavation mud separation and purification device provided by the present invention includes a temporary storage box 1 and a sedimentation box. The sedimentation box is a commonly used structure for sewage purification, and mud and water stratification is achieved by sedimentation. It is not shown in this figure. One side of the temporary storage box 1 is fixedly connected to the slag guide trough 11. A slag receiving box is placed on the side of the temporary storage box 1 to receive the crushed slag discharged from the slag guide trough 11. The other side of the temporary storage box 1 is rotatably connected to the circular pipe 12. The temporary storage box 1 is fixedly connected to the bracket 13, and the bracket 13 is fixedly connected to the inner pipe 14. The circular pipe 12 is rotatably sleeved on the outside of the inner pipe 14 and rotatably connected, and the end of the circular pipe 12 extending into the temporary storage box 1 is a closed structure. The other end of the inner pipe 14 is connected to a water pump. The water pump draws the filtered mud and water into the sedimentation box for sedimentation and stratification treatment. The other end of the circular pipe 12 is fixedly connected to the extraction and filtering device 2;

[0026] The extraction and filtering device 2 includes a branch pipe 21, which is fixedly connected to a guide inclined plate 211. The hard mud, gravel, and debris entering are guided by the guide inclined plate 211 to the slag guide trough 11 for discharge. The branch pipe 21 is connected to the circular pipe 12. A filter cartridge 22 is provided at the end of the branch pipe 21 away from the circular pipe 12. A suction pipe 23 is provided at the bottom of the filter cartridge 22. The upper end of the suction pipe 23 is hingedly connected to a baffle 24, and a torsion spring is provided on the hinge axis of the baffle 24. When the branch pipe 21 is sucking, the water flow pushes open the baffle 24. When the branch pipe 21 loses suction, the torsion spring causes the baffle 24 to rotate and close the suction pipe 23, and the gravel remains in the filter cartridge 22. A discharge port 25 is provided at the upper end of the filter cartridge 22. After the filter cartridge 22 is turned over, the gravel is discharged through the discharge port 25.

[0027] The bracket 13 is fixedly connected to the driving device 3, and the driving device 3 drives the circular tube 12 to rotate alternately forward and reverse on the inner tube 14. The driving device 3 includes a servo motor 31, which is fixedly connected to one side of the bracket 13. The main shaft of the servo motor 31 is fixedly connected to the first pulley 32, and the circular tube 12 is coaxially fixedly connected to the second pulley 33. A transmission belt 34 is provided between the first pulley 32 and the second pulley 33; the servo motor 31 is convenient for controlling the rotation angle, so that the two extraction and filtering devices 2 can be alternately rotated to the top for slag discharge operation.

[0028] The present invention uses a water pump in conjunction with a controller of the prior art to produce a periodic suction action. During suction, sewage mixed with gravel flows, and the gravel enters the filter cartridge 22 through the suction pipe 23 and is filtered and blocked by the upper end of the filter cartridge 22. When suction is stopped, the gravel falls into the annular groove between the suction pipe 23 and the inner wall of the filter cartridge 22 under the influence of gravity. After multiple suction-pauses, a large amount of gravel remains in the filter cartridge 22. The driving device 3 drives the circular tube 12 to rotate the filter cartridge 22 located in the temporary storage box 1 upward. Under the action of gravity, the gravel is discharged from the discharge port 25 and guided by the guide inclined plate 211 to the slag guide trough 11 for discharge, which facilitates the separation of gravel and debris in the mud and reduces the influence of gravel on the suction blockage of muddy water.

[0029] Example 2

[0030] As shown in Figures 1-4, the top of the filter cartridge 22 is spherical, and the discharge port 25 is provided on the spherical surface. The branch pipe 21 slides through the spherical surface and is fixedly connected to the curved filter plate 4 at this end. The curved filter plate 4 is larger than the through hole of the branch pipe 21 sliding through the spherical surface, so that the branch pipe 21 can slide relative to the filter cartridge 22 without falling off. The inner wall of the filter cartridge 22 is fixedly connected to two support rods 41, and the two support rods 41 are jointly fixedly connected to the guide curved plate 42; the branch pipe 21 performs suction, and the lower part of the branch pipe 21 is blocked by the guide curved plate 42. The water flow can only reach the branch pipe 21 laterally, and gravel is easy to gather on the side. When the branch pipe 21 stops suctioning, the gravel falls into the annular groove between the suction pipe 23 and the inner wall of the filter cartridge 22 due to gravity and is retained. The gravel will not return to the temporary storage box 1, and the gravel is separated in time, thereby maintaining smooth muddy water suction.

[0031] Furthermore, protrusions 43 are evenly arranged on the inner curved surface of the guide curved plate 42, and the protrusions 43 correspond to the filter holes of the curved filter plate 4. When the filter cartridge 22 rotates upward and forms a state facing the discharge port 25, the filter cartridge 22 slides down relative to the branch pipe 21 under the action of gravity, and the protrusions 43 on the inner curved surface of the guide curved plate 42 hit the filter holes of the curved filter plate 4 to dredge and crush the hard mud blocks, thereby dredging the filter holes blocked in the curved filter plate 4.

[0032] Furthermore, an air pump or an automatic air supply device 5 is provided on the side of the branch pipe 21. After the branch pipe 21 stops suctioning, the air pump or the automatic air supply device 5 inflates the branch pipe 21. The end of the branch pipe 21 is covered by the guide arc plate 42, and the inflated gas needs to be discharged, so an upward push is formed on the guide arc plate 42 and the filter cartridge 22. The intermittent input of gas is controlled so that the guide arc plate 42 and the filter cartridge 22 are repeatedly raised and lowered relative to the branch pipe 21, repeatedly dredging the arc filter plate 4 at the end of the branch pipe 21 and crushing the mud blocks, while facilitating the vibration and falling of the filter cartridge 22, thereby discharging the debris in time while maintaining smooth suction of the branch pipe 21.

[0033] Example 3

[0034] As shown in Figures 1-4, the automatic air supply device 5 includes two inclined rods 51, which are fixedly connected to the two ends of the upper side of the temporary storage box 1 respectively. The upper ends of the two inclined rods 51 are fixedly connected to the cross bar 52. The side of the branch pipe 21 is fixedly connected to the cylinder barrel 53. An air inlet pipe 54 is provided on one side of the cylinder barrel 53. An air outlet pipe 55 is fixedly connected between the other side of the cylinder barrel 53 and the branch pipe 21. The air inlet pipe 54 and the air outlet pipe 55 are respectively provided with a one-way air valve. The one-way air valve is a prior art. The gas can only flow in one direction. A piston plate 56 is slidably connected in the cylinder barrel 53. A support spring 57 is fixedly connected between the piston plate 56 and the end wall of the cylinder barrel 53. A piston rod 58 is fixedly connected to one side of the piston plate 56. The piston rod 58 extends out of one end of the cylinder barrel 53 and is rotatably connected to a circular column 59. The circular column 59 can squeeze and contact the bottom of the cross bar 52.

[0035] Furthermore, arc-shaped grooves 521 are provided at intervals at the bottom of the crossbar 52 .

[0036] Simply using an air pump is not convenient for finding the right time for the air pump to work. In this embodiment, one of the extraction and filtering devices 2 is swung upward through the circular tube 12. During the rotation of the extraction and filtering device 2, the circular column 59 on the side of the piston rod 58 on the cylinder barrel 53 of the automatic air supply device 5 forms an annular movement path. When the circular column 59 encounters the obstruction of the cross bar 52, the circular column 59 and the piston rod 58 passively pull the piston plate 56 and compress the support spring 57, so that the gas in the cylinder barrel 53 is pressed into the branch pipe 21.

[0037] One end of the inner tube 14 is a flange, and the other end of the inner tube 14 is a closed structure with a through hole 141 at the bottom. The lower end of the branch pipe 21 rotated upward is blocked by the upper side of the inner tube 14. The gas injected into the branch pipe 21 can only overflow from the upper end of the branch pipe 21, thereby forming a clearing effect on the upper end of the branch pipe 21.

[0038] Furthermore, on the basis of the dredging effect, it is also necessary to cooperate with the lifting or lowering effect of the filter cartridge 22 relative to the branch pipe 21 to enhance the effect of crushing mud blocks and dredging, and at the same time facilitate the vibration discharge of debris in the filter cartridge 22. This only requires the arc-shaped grooves 521 to be arranged at intervals at the bottom of the cross bar 52. If the bottom of the cross bar 52 is flat, air will be continuously input through the circular column 59 as it rotates. When the circular column 59 falls into the arc-shaped groove 521 and temporarily suspends the pulling of the piston rod 58, under the action of gravity, the filter cartridge 22 descends and blocks the upper end of the branch pipe 21 through the guide arc plate 42. The circular column 59 leaves the arc-shaped groove 521, and further input airflow is formed. The filter cartridge 22 will be pushed away, thereby achieving the above-mentioned effect, thereby facilitating the effect of crushing mud blocks and dredging, and at the same time facilitating the vibration discharge of debris in the filter cartridge 22.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
