Description

Technical Field

[0001] This invention relates to the field of drilling mud treatment technology, and in particular to a device for separating and purifying drilling mud from bridge pile foundation excavation. Background Technology

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

[0003] The mud contains hard mud lumps, gravel, etc., which can easily clog the suction pipes for pumping mud, making it difficult for mud to circulate or be discharged. This requires frequent manual or mechanical retrieval of the suction pipes, and the unblocking process requires methods such as reverse flushing, which affects the continuous operation of mud separation and makes unblocking inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mud separation and purification device for bridge pile foundation excavation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bridge pile foundation excavation mud separation and purification device includes a temporary storage tank and a sedimentation tank. A slag guide channel is fixedly connected to one side of the temporary storage tank, and a circular pipe is rotatably connected to the other side of the temporary storage tank. A support is fixedly connected to the temporary storage tank, and an inner pipe is fixedly connected to the support. The circular pipe is rotatably sleeved on the outside of the inner pipe and rotatably connected. A water pump is connected to the other end of the inner pipe, and an extraction and filtration device is fixedly connected to the other end of the circular pipe.

[0007] The extraction and filtration device includes a branch pipe connected to a round pipe. A filter cylinder is provided at the end of the branch pipe away from the round pipe. A suction pipe is provided at the bottom of the filter cylinder. A baffle is hinged to the upper end of the suction pipe, and a torsion spring is provided on the hinge shaft of the baffle. An outlet is provided at the upper end of the filter cylinder.

[0008] The bracket is fixedly connected to the driving device, which drives the round tube to rotate alternately.

[0009] Preferably, the top of the filter cylinder is spherical, the outlet is located on the spherical surface, the branch pipe slides through the spherical surface and is fixedly connected to the arc-shaped filter plate at this end, and two support rods are fixedly connected to the inner wall of the filter cylinder, and the two support rods are jointly fixedly connected to the flow guiding arc-shaped plate.

[0010] Preferably, the inner arc surface of the flow guide plate is uniformly provided with protrusions, which correspond to the filter holes of the arc-shaped filter plate.

[0011] Preferably, an air pump or automatic air supply device is provided on the side of the branch pipe.

[0012] Preferably, the automatic air supply device includes two inclined rods, which are fixedly connected to the upper ends of the temporary storage box. The upper ends of the two inclined rods are fixedly connected to a crossbar. A cylinder is fixedly connected to the side of the branch pipe. An air inlet pipe is provided on one side of the cylinder, and an air outlet pipe is fixedly connected between the other side of the cylinder and the branch pipe. One-way valves are provided on the air inlet pipe and the air outlet pipe respectively. A piston plate is slidably connected inside the cylinder. A support spring is fixedly connected between the piston plate and the end wall of the cylinder. A piston rod is fixedly connected to one side of the piston plate. A circular cylinder is rotatably connected to one end of the piston rod that extends out of the cylinder. The circular cylinder can press against the bottom of the crossbar.

[0013] Preferably, the bottom of the crossbar is provided with arc-shaped grooves at intervals.

[0014] Preferably, the branch pipe is fixedly connected to a guide inclined plate.

[0015] Preferably, the driving device includes a servo motor, which is fixedly connected to one side of the bracket. The main shaft of the servo motor is fixedly connected to a first pulley, and a round tube is coaxially fixedly connected to a second pulley. A transmission belt is provided between the first pulley and the second pulley.

[0016] The advantages of this invention are as follows: The bridge pile foundation excavation mud separation and purification device provided by this invention uses a water pump to periodically pump the mud. During pumping, sewage mixed with gravel flows, and the gravel enters the filter cylinder through the suction pipe and is blocked by the filter at the top of the filter cylinder. When pumping stops, the gravel falls into the annular groove between the suction pipe and the inner wall of the filter cylinder due to gravity. After multiple pumping and pausing cycles, a large amount of gravel remains in the filter cylinder. The driving device drives the circular pipe to rotate the filter cylinder located in the temporary storage box to the top. Under the action of gravity, the gravel is discharged from the discharge port and guided by the guide inclined plate to the slag guide trough for discharge. This facilitates the separation of gravel and debris in the mud and reduces the impact of gravel on the pumping and clogging of the mud and water.

[0017] This invention, in addition to its unblocking effect, also requires the filter cylinder to rise or fall relative to the branch pipe to enhance the crushing and unblocking effect of mud lumps. At the same time, it facilitates the vibration discharge of debris from the filter cylinder. This is achieved by setting arc-shaped grooves at intervals at the bottom of the crossbar. If the bottom of the crossbar is flat, air will be continuously input through the circular column as it rotates. When the circular column falls into the arc-shaped groove and temporarily stops pulling the piston rod, the filter cylinder descends under the action of gravity and blocks the upper end of the branch pipe through the guide arc-shaped plate. The circular column leaves the arc-shaped groove, forming a further input airflow, which pushes the filter cylinder open, thereby achieving the above-mentioned effects. This facilitates the crushing and unblocking effect of mud lumps and also facilitates the vibration discharge of debris from the filter cylinder. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 merely illustrative and not intended to limit the invention.

[0023] Example 1

[0024] like Figure 1-4 As shown in the figure, the present invention provides a mud separation and purification device for bridge pile foundation excavation, including a temporary storage tank 1 and a sedimentation tank. The sedimentation tank is a commonly used structure for sewage purification, which achieves mud-water stratification through sedimentation. It is not shown in the figure. A slag guide trough 11 is fixedly connected to one side of the temporary storage tank 1. A slag receiving box is placed on the side of the temporary storage tank 1 to receive the slag discharged from the slag guide trough 11. A circular pipe 12 is rotatably connected to the other side of the temporary storage tank 1. A bracket 13 is fixedly connected to the temporary storage tank 1. The bracket 13 is fixedly connected to an inner pipe 14. The circular pipe 12 is rotatably sleeved on the outside of the inner pipe 14 and rotatably connected. The end of the circular pipe 12 that extends into the temporary storage tank 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-water into the sedimentation tank for sedimentation and stratification. The other end of the circular pipe 12 is fixedly connected to an extraction and filtration device 2.

[0025] The extraction and filtration device 2 includes a branch pipe 21, which is fixedly connected to a guide inclined plate 211. The hard mud, gravel, and debris that enter are guided by the guide inclined plate 211 to the slag discharge trough 11. The branch pipe 21 is connected to a circular pipe 12. A filter cylinder 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 cylinder 22. A baffle 24 is hinged to the upper end of the suction pipe 23, and a torsion spring is provided on the hinge shaft of the baffle 24. When the branch pipe 21 performs suction, 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 is left in the filter cylinder 22. A discharge port 25 is provided at the upper end of the filter cylinder 22. After the filter cylinder 22 is flipped, the gravel is discharged from the discharge port 25.

[0026] The support 13 is fixedly connected to the drive device 3, which drives the round tube 12 to rotate alternately in both directions on the inner tube 14. The drive device 3 includes a servo motor 31, which is fixedly connected to one side of the support 13. The main shaft of the servo motor 31 is fixedly connected to the first pulley 32, and the round 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 facilitates the control of the rotation angle, so that the two extraction and filtering devices 2 can rotate alternately to the top to perform slag discharge operations.

[0027] This invention uses a water pump in conjunction with a controller based on existing technology to generate a periodic suction action. During suction, sewage mixed with gravel flows, and the gravel enters the filter cylinder 22 through the suction pipe 23 and is blocked by the filter at the upper end of the filter cylinder 22. When suction stops, the gravel falls into the annular groove between the suction pipe 23 and the inner wall of the filter cylinder 22 due to gravity. After multiple suction and pauses, a large amount of gravel remains in the filter cylinder 22. The drive device 3 drives the circular pipe 12 to rotate the filter cylinder 22 located in the temporary storage box 1 to the top. 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 impact of gravel on the suction and blockage of mud and water.

[0028] Example 2

[0029] like Figure 1-4 As shown, the top of the filter cylinder 22 is spherical, and the outlet 25 is located on the spherical surface. The branch pipe 21 slides through the spherical surface and is fixedly connected to the arc-shaped filter plate 4 at this end. The arc-shaped filter plate 4 is larger than the through hole through which the branch pipe 21 slides through the spherical surface, so that the branch pipe 21 can slide relative to the filter cylinder 22 without falling off. Two support rods 41 are fixedly connected to the inner wall of the filter cylinder 22, and the two support rods 41 are fixedly connected to the flow-guiding arc plate 42. The branch pipe 21 performs a suction function. The bottom of the branch pipe 21 is blocked by the flow-guiding arc plate 42, so the water flow can only reach the branch pipe 21 laterally. The gravel is easy to accumulate on the side. When the branch pipe 21 stops suction, the gravel is easy to fall into the annular groove between the suction pipe 23 and the inner wall of the filter cylinder 22 due to gravity. The gravel will not return to the temporary storage box 1, and the gravel is separated in time, thereby maintaining the smooth suction of mud and water.

[0030] Furthermore, the inner arc surface of the flow guide arc plate 42 is uniformly provided with protrusions 43, which correspond to the filter holes of the arc filter plate 4. When the filter cylinder 22 rotates to the top and forms the state of the outlet 25 facing, the filter cylinder 22 slides down relative to the branch pipe 21 under the action of gravity. The protrusions 43 on the inner arc surface of the flow guide arc plate 42 hit the filter holes of the arc filter plate 4 to form a function of clearing and crushing hard mud, thereby clearing the filter holes of the arc filter plate 4 that are blocked.

[0031] Furthermore, an air pump or automatic air supply device 5 is provided on the side of the branch pipe 21. After the branch pipe 21 stops pumping, the air pump or automatic air supply device 5 fills the branch pipe 21 with air. The end of the branch pipe 21 is covered by the guide arc plate 42. The filled gas needs to be discharged, so it forms an upward pushing effect on the guide arc plate 42 and the filter cylinder 22, controlling the intermittent input of gas. This causes the guide arc plate 42 and the filter cylinder 22 to rise and fall repeatedly relative to the branch pipe 21, repeatedly clearing and crushing the mud on the arc filter plate 4 at the end of the branch pipe 21. At the same time, it facilitates the vibration and fall of the filter cylinder 22, thereby timely discharging the debris while maintaining the smooth pumping of the branch pipe 21.

[0032] Example 3

[0033] like Figure 1-4 As shown, the automatic air supply device 5 includes two inclined rods 51, which are fixedly connected to the upper ends of the temporary storage box 1. The upper ends of the two inclined rods 51 are fixedly connected to a crossbar 52. The side of the branch pipe 21 is fixedly connected to a cylinder 53. One side of the cylinder 53 is provided with an air inlet pipe 54, and the other side of the cylinder 53 is fixedly connected to the branch pipe 21 with an air outlet pipe 55. The air inlet pipe 54 and the air outlet pipe 55 are respectively provided with one-way valves. The one-way valves are existing technology, and the gas can only flow in one direction. A piston plate 56 is slidably connected inside the cylinder 53. A support spring 57 is fixedly connected between the piston plate 56 and the end wall of the cylinder 53. A piston rod 58 is fixedly connected to one side of the piston plate 56. One end of the piston rod 58 that extends out of the cylinder 53 is rotatably connected to a circular column 59. The circular column 59 can press and contact the bottom of the crossbar 52.

[0034] Furthermore, the bottom of the crossbar 52 is provided with arc-shaped grooves 521 at intervals.

[0035] Simply using an air pump makes it difficult to find the right time for the air pump to work. In this embodiment, one of the extraction and filtering devices 2 is swung upwards 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 53 of the automatic air supply device 5 moves in an annular path. When the circular column 59 encounters the obstruction of the crossbar 52, the circular column 59 and the piston rod 58 passively pull the piston plate 56 and compress the support spring 57. The gas in the cylinder 53 is forced into the branch pipe 21.

[0036] 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 tube 21 rotated to the top is blocked by the upper side of the inner tube 14. The gas injected into the branch tube 21 can only overflow from the upper end of the branch tube 21, thus forming a clearing effect on the upper end of the branch tube 21.

[0037] Furthermore, in addition to the unblocking effect, it is also necessary to coordinate with the lifting or lowering action of the filter cylinder 22 relative to the branch pipe 21 to enhance the crushing of mud and the unblocking effect, while facilitating the vibration discharge of debris from the filter cylinder 22. This only requires setting arc-shaped grooves 521 at intervals at the bottom of the crossbar 52. If the bottom of the crossbar 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 stops pulling the piston rod 58, the filter cylinder 22 descends under the action of gravity 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, forming a further input airflow. The filter cylinder 22 will be pushed open, thereby achieving the above-mentioned effects, which facilitates the crushing of mud and the unblocking effect, while facilitating the vibration discharge of debris from the filter cylinder 22.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
