Description

Technical Field

[0001] This utility model relates to the technical field of mud circulation filtration devices, and in particular to a mud circulation filtration device for cast-in-place piles. Background Technology

[0002] The pile hole mud circulation system uses a mud pump to deliver high-pressure mud from the mud pit into the pile hole, and then ejects it from the bottom of the hole through a mud inlet pipe installed inside the hole. Drill cuttings suspended in the mud at the bottom of the hole overflow as the mud rises, settle in a sedimentation tank, and then flow back into the mud pit for reuse. Since the operation efficiency is low when using natural sedimentation, appropriate filtration devices are used to filter the mud.

[0003] A Chinese patent with publication number CN214763923U discloses a mobile drilling grouting pile mud filtration and circulation system, which includes: a circulation filter box arranged adjacent to the pile hole, in which a first mud pump is installed, the first mud pump being connected to the bottom of the pile hole through an input conduit; a filter mechanism with a sloped filter screen is installed above the end of the circulation filter box away from the pile hole; and a sedimentation tank arranged adjacent to the filter mechanism and close to the bottom side of the sloped filter screen, wherein when the mud flows through the sloped filter screen, the filtered sediment settles into the sedimentation tank by its own gravity.

[0004] Regarding the aforementioned technologies, it was found that the circulation system uses a slope filter screen to separate mud and drilling cuttings and other impurities. In the early stages of the circulation process, the filter screen can ensure a good filtration effect. However, as the filtration time increases, the filter screen holes will be continuously blocked by various impurities or mud. As a result, most of the mud will flow into the sedimentation tank, which will lead to less and less mud that can be circulated, affecting the normal continuous circulation operation of the system. At the same time, the slope filter screen is fixed on the filter box and is not easy to replace quickly. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a mud circulation and filtration device for cast-in-place piles.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0028] Reference Figure 1 , Figure 2 and Figure 3 As shown, a slurry circulation filtration device for cast-in-place piles includes a filter support 1. The filter support 1 includes a base plate 11 and an angle bracket 12. The angle bracket 12 is installed on the upper end face of the base plate 11 and is rotatably connected to the base plate 11. A diversion shell 5 is fixedly installed at the head of the angle bracket 12. A plurality of diversion grooves 51 are evenly opened and closed on the lower end face of the diversion shell 5. A filter assembly 2 is inserted and installed in the middle of the angle bracket 12. An elastic locking piece 3 for locking the filter assembly 2 is also installed on the angle bracket 12. A cleaning pendulum group 4 that cooperates with the filter assembly 2 is also installed on the angle bracket 12. By designing the filter support 1 as a structure in which the base plate 11 and the corner bracket 12 cooperate, it can be easily fixedly installed on the mud tank using the base plate 11. The corner bracket 12 can be rotated and installed on the base plate 11 for easy adjustment during use. A diversion shell 5 is fixedly installed at the head of the corner bracket 12 to receive the circulating mud. This ensures that after the mud enters the diversion shell 5, it can flow downwards to the filter assembly 2 for filtration. The filtered mud can then pass through the filter assembly. The filter assembly 2 flows into the mud pool at the lower end for recycling, while the filtered impurities can flow out along the surface of the filter assembly 2 into the external sedimentation tank. The filter assembly 2 is locked by an elastic locking member 3 installed on the corner frame 12. After the filter assembly 2 is inserted into the corner frame 12, it can be quickly locked by the elastic locking member 3 to ensure that the filter assembly 2 can be used stably. Furthermore, by installing a cleaning assembly 4 on the corner frame 12, the upper end of the filter assembly 2 can be cleaned by the cleaning assembly during the process, reducing the clogging of the filter mesh by impurities.

[0029] Reference Figure 2 and Figure 3As shown, the angle bracket 12 includes a vertical baffle 121 and an inclined frame 122. The inclined frame 122 is installed obliquely at the head of the vertical baffle 121 and is fixedly connected to the vertical baffle 121. A central groove 123 for installing the filter assembly 2 is provided in the middle of the inclined frame 122. Limiting grooves 124 are symmetrically provided on both sides of the central groove 123. Two sets of auxiliary upright plates 125 are installed on the upper end surface of the inclined frame 122. The two sets of auxiliary upright plates 125 are arranged on both sides of the central groove 123 and are fixedly connected to the inclined frame 122. By designing the corner bracket 12 as a structure in which the vertical baffle 121 and the inclined frame 122 cooperate, it is easy to use. The vertical baffle 121 can be rotated and connected to the seat plate 11, and the inclined frame 122 is used to install the filter assembly 2. The middle groove 123 and the limiting slide groove 124 facilitate the stable insertion and installation of the filter assembly 2. When it needs to be replaced, it is easy to directly pull it out for disassembly. The auxiliary vertical plate 125 is set to ensure that the mud flows better on the filter assembly 2 and avoids side flow.

[0030] Reference Figure 6 As shown, the filter assembly 2 includes a central mesh portion 21 and side frames 22. The side frames 22 are fixedly installed on both sides of the central mesh portion 21 and are slidably installed in the limiting groove 124. A limiting strip 221 is fixedly installed at the head of the side frame 22. By designing the filter assembly 2 into a structure in which the central mesh portion 21 and the side frames 22 cooperate, the central mesh portion 21 can be stably installed in the limiting groove 124 through the side frames 22 on both sides when it is easy to use.

[0031] Reference Figure 1 , Figure 4 and Figure 6 As shown, the elastic locking element 3 includes a sleeve shell 31 and a hook plate 32 that cooperates with the limiting strip 221. The sleeve shell 31 is installed on the head of the hook plate 32, and the sleeve shell 31 and the hook plate 32 are integrally formed. A positioning shaft 126 for rotating the sleeve shell 31 is fixedly provided on the upper end face of the inclined frame 122. A limiting cover 127 is fixedly installed on the head of the positioning shaft 126, and a torsion spring 128 is installed between the limiting cover 127 and the sleeve shell 31. By designing the elastic locking element 3 into a structure in which the sleeve shell 31 and the hook plate 32 cooperate, the hook plate 32 can be sleeved and installed on the positioning shaft 126 of the inclined frame 122 through the sleeve shell 31 when it is easy to use. At the same time, the setting of the limiting cover 127 ensures that the sleeve shell 31 is more stable when installed on the positioning shaft 126. The setting of the torsion spring 128 ensures that the hook plate 32 can stably lock the limiting strip 221 when there is no external force. When the filter assembly 2 needs to be disassembled, the operator can turn the elastic locking element 3 to release the lock.

[0032] Reference Figure 1As shown, the cleaning pendulum assembly 4 includes a pendulum motor 41 and a pendulum rod 42. The pendulum motor 41 is fixedly installed in the middle of the diverter housing 5, and one end of the pendulum rod 42 is connected to the output shaft of the pendulum motor 41. By designing the cleaning pendulum assembly 4 into a structure in which the pendulum motor 41 and the pendulum rod 42 cooperate, the pendulum motor can be used to drive the pendulum rod 42 to swing back and forth on the upper end face of the mesh section 21 when it is easy to use. This can effectively reduce the adhesion of impurities in the mesh and thus reduce the clogging of the mesh.

[0033] In this embodiment, during actual use, the mud coming out of the borehole can flow steadily into the diversion shell 5. Then, the mud can flow evenly from the diversion groove 51 at the lower end of the diversion shell 5 to different positions on the filter assembly 2, facilitating better filtration. At the same time, the swing motor 41 is turned on to drive the swing rod 42 to swing, or the swing motor 41 is turned on at regular intervals to drive the swing rod 42 to swing. The swinging swing rod 42 cleans the impurities on the middle mesh 21, ensuring that the mud can flow steadily into the mud pool at the lower end, while the impurities can flow steadily along the middle mesh 21 into the external sedimentation tank. When the filter assembly 2 needs to be replaced, the operator can flip up the corner frame 12, and then the operator can move the elastic lock 3 to release the lock on the filter assembly 2. In this way, the filter assembly 2 can be pulled out directly. Finally, the new filter assembly 2 can be inserted into the middle groove 123 of the corner frame 12.

[0034] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
