Description

Technical Field

[0001] The invention specifically relates to the technical field of mud treatment, in particular to a mud treatment device for building pile foundation construction. Background Art

[0002] With the development of the economy and the continuous acceleration of the urbanization process, the construction industry has developed more and more rapidly, and more and more buildings are built on complex foundations. Pile foundation engineering has become one of the most commonly used forms of construction. For complex foundations such as weak foundations, block stones, or ultra-deep and ultra-large diameter pile foundations, mechanical mud wall protection and hole forming technology is increasingly being used as a mature technology for construction. In the prior art, during construction, a mud pool is set up on the site plane to mix mud or as a circulating mud pool. As the drilling progresses, the mud indicators in the borehole are repeatedly measured, and a mud pump is used to add slurry to the borehole. After the mud circulates out of the borehole, the mud is mixed with the drill bit and is difficult to separate. After natural sedimentation, a small part of the mud is reused as wall protection mud, and most of the mud is mixed with the drill bit and transported to an off-site storage site by a mud truck. After a long period of natural sedimentation, it can be used as a resource. Sometimes, due to environmental protection requirements, mud purifiers are used during pile foundation construction to purify the mud circulating in the borehole and then recycle it as a resource. The device uses the principle of centrifugal decomposition to separate the mud from the drilling cuttings, and the separated mud can be reused.

[0003] In order to improve the separation effect of mud and drill cuttings in pile foundation construction, a pile foundation slag cleaning system with authorization announcement CN205206764U is disclosed in a Chinese patent, including a mud suction pipe, a frame, and a water supply system, a mud pump and a filtering device respectively installed on the frame, wherein one end of the mud suction pipe extends into the pile foundation hole, the other end of the mud suction pipe is connected to the water inlet of the mud pump, the water supply system is connected to the inside of the mud pump, and the water outlet of the mud pump is connected to the filtering device, and the filtering device performs filtering residue treatment on the mud transported thereto; the filtering device includes a filter box, a filter screen plate transversely arranged inside the filter box, and a plurality of vibrators symmetrically installed on the filter box, and a shock absorber is installed between the filter box and the frame. Although the system has achieved the separation of mud and drill cuttings to a certain extent, the system still has the following disadvantages: 1) The system is provided with two filter screens, and all the filter screens are arranged in the horizontal direction. Although the filter screen has a good filtering effect, it is difficult to remove the drill cuttings on the filter screen after the filtering operation is completed. The system is provided with a screw conveyor for removing the drill cuttings on the filter screen. Since the filter screen is located in the horizontal direction, although the screw conveyor is tilted, only a small part of the drill cuttings can enter the screw conveyor and be transported out. After a long time, the drill cuttings are trapped on the filter screen. The plate is deposited, which hinders the subsequent filtration of mud. At the same time, the filter screen plate will be damaged due to the large amount of drill cuttings. The operation of the screw conveyor will also consume a lot of energy, which cannot meet the modern energy-saving and environmental protection needs; 2) A vibrator is set on the filter box of the system to vibrate the entire filter box (including the filter screen plate). However, in order to increase the separation speed of mud and drill cuttings, it is only necessary to vibrate the filter screen plate. Therefore, a vibrator is set on the entire filter box, which requires a lot of energy to vibrate the filter box. At the same time, the filter box will be quickly damaged if it vibrates for a long time. Summary of the invention

[0004] The object of the present invention is to provide a mud processing device for building pile foundation construction to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

When the telescopic end of the component is shortened to the second position, the outer end of the filter mechanism is pulled downward to the lower side of the slag discharge port. At this time, the filter mechanism is inclined toward the slag discharge port, and the waste slag intercepted by the filter mechanism is directly discharged from the slag discharge port; a discharge port is provided at the bottom of the processing chamber, and the discharge port is connected to a discharge pipe, and the discharge pipe includes a pipe body and a control valve rotatably installed inside the pipe body, and the control valve has an open state and a closed state.

When the control valve is in an open state, the raised portion is opposite to the feed side of the pipe body. The raised portion guides the mud being discharged from the pipe body to improve the mud discharge efficiency. In addition, in order to enable the control valve to rotate smoothly inside the pipe body, an arc groove matched with the raised portion is provided on the inner wall of the pipe body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The mud treatment device for construction pile foundation described in the present invention has a slag discharge port on the side of the treatment chamber inside the treatment device, and uses a filtering mechanism to filter the mud while controlling the rotation state of the filtering mechanism to open and close the slag discharge port, thereby realizing rapid discharge of waste slag, and uses a synchronization mechanism to synchronously drive the control valve to rotate when the filtering mechanism is in a rotating state, so that the slag discharge port and the discharge pipe are synchronously kept closed during filtering and synchronously kept open during slag discharge, thereby quickly discharging waste slag and mud, improving the slag discharge speed and the treatment efficiency of the mud treatment device, and solving the problem of difficult slag discharge in existing mud treatment equipment;

[0021] (2) The mud processing device for construction pile foundation described in the present invention can filter out waste residues with larger diameters mixed in the mud by means of a filtering mechanism arranged inside the processing device, thereby reducing the influence of large-particle waste residues on mud stirring and improving the uniformity of subsequent mud stirring.

The efficiency of mud stirring is increased by removing the influence of large particles of waste residue on mud filtration, and the functions of various mechanisms can be more efficiently utilized and coordinated.

[0035] It should be understood that although the terms first, second, etc. may be used to describe various information in the embodiments of the present invention, the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other.

[0036] Based on this, see Figure 1-5 In the embodiment of the present invention, a construction pile foundation construction mud processing device is used for processing and recycling waste mud at the construction pile foundation construction site. The processing device includes a processing device 20, a filtering mechanism 40 and a mixing mechanism 50. Figure 6As shown, a processing chamber 22 is provided inside the processing equipment 20, and the filtering mechanism 40 and the mixing mechanism 50 are installed inside the processing chamber 22. The filtering mechanism 40 and the mixing mechanism 50 are sequentially arranged along the flow direction of the mud. In this embodiment, the filtering mechanism 40 is arranged above the mixing mechanism 50. The filtering mechanism 40 is used to filter out the waste residue with a larger diameter mixed in the mud. After the waste residue is filtered out, the remaining mud passes through the filtering mechanism 40 and enters the lower space of the processing chamber 22. The mixing mechanism 50 stirs the mud to make the solid phase particles in the mud evenly distributed, thereby improving the porosity of the pile foundation.

[0037] In order to solve the problem of difficult slag discharge in existing mud treatment equipment, a slag discharge port 23 is opened on the side wall of the processing chamber 22, and the filtering mechanism 40 is rotatably arranged inside the processing chamber 22, and the rotating end of the filtering mechanism 40 is arranged away from the slag discharge port 23. A telescopic driving member 41 for driving the filtering mechanism 40 to rotate is arranged inside the processing chamber 22, and the telescopic end of the telescopic driving member 41 has an extended first position and a shortened second position. When filtering, the telescopic end of the telescopic driving member 41 is extended to the first position to push the outer end of the filtering mechanism 40 ( Figure 6 The left end of the filter mechanism 40 is moved upward to the upper side of the slag discharge port 23, and the mud and the waste residue intercepted by the filter mechanism 40 cannot flow out of the slag discharge port 23. When discharging slag, the telescopic end of the telescopic drive member 41 is shortened to the second position to pull the outer end of the filter mechanism 40 downward to the lower side of the slag discharge port 23. At this time, the filter mechanism 40 is tilted toward the slag discharge port 23, and the waste residue intercepted by the filter mechanism 40 is directly discharged from the slag discharge port 23.

[0038] Furthermore, in the embodiment of the present invention, a discharge port 25 is provided at the bottom of the processing chamber 22, and the discharge port 25 is connected to a discharge pipe 60, and the discharge pipe 60 includes a pipe body 61 and a control valve 62 rotatably mounted inside the pipe body 61, and the control valve 62 has an open state and a closed state. When filtering, the control valve 62 is rotated to the closed state to prevent the mud from being discharged from the discharge port 25, and when discharging slag, the control valve 62 is rotated to the open state to discharge the mud from the discharge port 25;

[0039] In the embodiment of the present invention, a synchronization mechanism 70 is further provided, and the synchronization mechanism 70 is used to synchronously drive the control valve 62 to rotate when the filtering mechanism 40 is in a rotating state. Further, the filtering mechanism 40 is rotatably installed inside the processing chamber 22 through the first rotating shaft 42, and the control valve 62 is rotatably installed inside the tube body 61 through the second rotating shaft 63. In addition, the synchronization mechanism 70 includes a first pulley 71 fixedly connected to the first rotating shaft 42, a second pulley 73 fixedly connected to the second rotating shaft 63, and a synchronous belt 72 connecting the first pulley 71 and the second pulley 73. It can be understood that when the filtering mechanism 40 rotates, the first rotating shaft 42 is driven to rotate, and then the synchronization mechanism 70 is rotated, so that the slag discharge port 23 and the discharge pipe 60 are synchronously kept closed during filtering and synchronously kept open during slag discharge, so that the waste slag and mud are quickly discharged;

[0040] In addition, the telescopic driving member 41 described in the embodiment of the present invention can be a telescopic cylinder, the telescopic end of the telescopic cylinder is rotatably connected to the bottom of the filtering mechanism 40, and the bottom of the telescopic cylinder is rotatably connected to the inner wall of the processing chamber 22.

[0041] like Figure 7 As shown, the filtering mechanism 40 includes a frame 43, a filtering plate 431 fixedly mounted on the frame 43, and a material pushing seat 44 slidably mounted on the frame 43. The material pushing seat 44 is an L-shaped structure. The outer end of the filtering mechanism 40 ( Figure 6 When the left end of the filter mechanism 40 is located at the upper side of the slag discharge port 23, the filter mechanism 40 tilts upward, and the pusher seat 44 slides to the right side of the frame 43 under the action of its own gravity. At this time, the mud entering the processing chamber 22 contacts the filter plate 431, and the waste residue intercepted by the filter plate 431 moves to the right and abuts against the pusher seat 44. When the outer end of the filter mechanism 40 is located at the lower side of the slag discharge port 23, the filter mechanism 40 tilts downward, and the pusher seat 44 slides to the left side of the frame 43 under the action of its own gravity, and pushes the waste residue out of the slag discharge port 23, thereby increasing the slag discharge speed;

[0042] Furthermore, in the embodiment of the present invention, a first slide groove 433 is provided on the outer wall of the frame 43, and the pusher seat 44 is slidably installed inside the first slide groove 433 through a slider; in addition, a guide block 432 is also installed on the frame 43, and a guide groove for sliding the guide block 432 is provided on the inner wall of the processing chamber 22. Since the sliding trajectory of the filter mechanism 40 is arc-shaped, the guide groove is set to be an arc groove concentric with the sliding trajectory of the filter mechanism 40. In addition, the outer end of the filter mechanism 40 and the inner side surface of the slag discharge port 23 are also set to be arc-shaped.

[0043] See also Fig. 9The control valve 62 has a recessed portion 621 and a raised portion 622. When the control valve 62 is in a closed state, the recessed portion 621 is directly opposite to the feed side of the tube body 61. At this time, the recessed portion 621 stores the mud entering the tube body 61 to prevent the mud from discharging from the tube body 61. When the control valve 62 is in an open state, the raised portion 622 is directly opposite to the feed side of the tube body 61. The raised portion 622 guides the mud being discharged from the tube body 61 to improve the mud discharge efficiency. In addition, in order to enable the control valve 62 to rotate smoothly inside the tube body 61, an arc groove matched with the raised portion 622 is provided on the inner wall of the tube body 61. When the control valve 62 is in a closed state, the raised portion 622 of the control valve 62 is close to the arc groove to prevent the mud from flowing out of the gap between the raised portion 622 and the arc groove.

[0044] See also Figure 8 In the embodiment of the present invention, the mixing mechanism 50 includes a driving shaft 51 rotatably mounted inside the processing chamber 22, a sleeve 52 slidably mounted on the driving shaft 51, a plurality of stirring mechanisms 53 evenly arranged around the sleeve 52, and a mounting seat 55 fixedly mounted inside the processing chamber 22. At least one top block 54 is fixedly mounted on the outer end of the sleeve 52. In this embodiment, the top block 54 is spherical, and a plurality of arc-shaped grooves 551 adapted to the top block 54 are provided on the mounting seat 55. Two adjacent arc-shaped grooves 551 are connected by an arc segment. When the driving shaft 51 rotates, the sleeve 52 is driven to rotate. The rotating sleeve 52 drives the spherical top block 54 to pass through each arc-shaped groove 551 in turn, so that the rotating sleeve 52 continuously slides left and right along the driving shaft 51, thereby expanding the stirring range of the stirring mechanism 53 inside the processing chamber 22 and improving the uniformity of the solid phase particles in the mud.

[0045] In order to enable the sleeve 52 to maintain reciprocating sliding, at least one second slide groove 511 is opened on the driving shaft 51. The inner side of the sleeve 52 is slidably installed inside the second slide groove 511 through a sliding block, and the sliding block is connected to the end of the second slide groove 511 through an elastic connecting member. In this embodiment, the elastic connecting member is a spring.

[0046] Furthermore, in the embodiment of the present invention, the stirring mechanism 53 includes a rotatable connecting shaft 531 and a plurality of stirring blades 532 fixedly mounted on the connecting shaft 531. The length of the stirring blades 532 on one side of the connecting shaft 531 is longer than that on the other side, so that the stirring mechanism 53 has a higher rotation efficiency under the drive of the driving shaft 51, thereby improving the stirring effect of the stirring mechanism 53 on the mud.

[0047] In addition, a driving motor 27 is installed on the outer side of the processing device 20 , and the output end of the driving motor 27 is fixedly connected to the driving shaft 51 for controlling the rotation of the driving shaft 51 .

[0049] In addition, a pumping port 26 is provided at the bottom of the processing chamber 22, and a pumping pump 34 is installed on the base 10. The feed end of the pumping pump 34 is connected to the pumping port 26 through a feed pipe, and the discharge end of the pumping pump 34 is connected to the feed end of the cyclone 30 through a discharge pipe 32, so as to pump the slurry that has been filtered and stirred in the processing chamber 22 into the cyclone 30 for re-separation.

[0050] Please refer again Figure 6 In the embodiment of the invention, an overflow port 24 is further provided on the upper side of the processing chamber 22. The overflow port 24 is used to discharge when the amount of mud in the processing chamber 22 reaches a preset value, thereby avoiding excessive amount of mud in the processing chamber 22, thereby reducing the equipment burden of the mixing mechanism 50, and reserving a certain material discharge space for the unfiltering mechanism 40 to improve the working efficiency of the overall equipment.

[0051] In summary, the present invention opens a slag discharge port 23 on the side of the processing chamber 22 inside the processing device, filters the mud by using the filter mechanism 40, and opens and closes the slag discharge port 23 by controlling the rotation state of the filter mechanism 40, so as to achieve rapid discharge of waste slag, and uses the synchronization mechanism 70 to synchronously drive the control valve 62 to rotate when the filter mechanism is in a rotating state, so that the slag discharge port 23 and the discharge pipe 60 are synchronously kept closed during filtering and synchronously kept open during slag discharge, thereby quickly discharging waste slag and mud, and improving the processing efficiency of the mud processing device; in addition, the present invention also sets a filter mechanism 40 and a mixing mechanism 50 inside the processing equipment 20, the filter mechanism 40 is used to filter out waste slag with a larger diameter mixed in the mud, and the remaining mud after the waste slag is filtered out enters the lower space of the processing chamber 22 through the filter mechanism 40, and the mixing mechanism 50 stirs the mud to make the solid phase particles in the mud evenly distributed, thereby improving the porosity of the pile foundation.
