Description

Technical Field

[0001] The utility model relates to the technical field of mud-water shield construction, in particular to a mud-water bin with an anti-sedimentation function. Background Art

[0002] During shield construction, a large amount of mud will be produced, so a mud circulation system is needed to circulate the mud. Due to the high mud content in the stratum and the insufficient screening accuracy, a large amount of mud will be deposited in the slurry mixing pool and the return slurry pool after multiple cycles, which greatly affects the viscosity and weight of the mud, and may even cause the suction port of the P11 pump to be blocked, making it impossible for the mud circulation to continue, affecting the progress of shield construction.

[0003] The prior art patent CN212225219U discloses an anti-sedimentation mud pool for a mud-water shield. By setting an air pipe and a first blowing hole, an external air source is used to input high-pressure air into the air pipe, and then blown out from the first blowing hole, which can effectively blow up the mud at the bottom of the mud pool, effectively avoiding the deposition of mud, ensuring the viscosity and weight of the mud, and ensuring the smooth circulation of the mud; at the same time, the setting of the check piece can effectively prevent the mud from infiltrating into the first blowing hole, ensuring the smooth flow of the air pipe.

[0004] However, in the above-mentioned prior art, the mud and water bin is large in size and cannot be fully covered by one stirring device, resulting in sedimentation in the mud and water bin. Setting up multiple stirring devices greatly increases energy consumption, which is very inconvenient. Utility Model Content

[0005] The purpose of the utility model is to provide a mud and water bin with an anti-sedimentation function, which solves the problem in the prior art that the mud and water bin is large in size and cannot be fully covered by one stirring device, resulting in the mud and water bin still being prone to sedimentation. The provision of multiple stirring devices greatly increases energy consumption, which is very inconvenient.

[0006] To achieve the above-mentioned purpose, the utility model provides a mud and water bin with anti-sedimentation function, comprising a shield machine body and a stirring assembly;

[0007] The stirring assembly includes a rotary cylinder, a rotating shaft, a stirring cylinder, a stirring block and a bottom rotating unit. The shield machine body has a mud and water bin. The rotary cylinder is fixedly connected to the shield machine body and is located inside the mud and water bin. One end of the rotating shaft is fixedly connected to the output end of the rotary cylinder, and the other end of the rotating shaft is fixedly connected to the stirring cylinder. The stirring cylinder is tilted on the rotating shaft, the stirring block is fixedly connected to the output end of the stirring cylinder, and the bottom rotating unit is arranged inside the mud and water bin.

[0008] Wherein, the stirring assembly further comprises a plurality of protrusions, and the plurality of protrusions are all fixedly connected to the stirring oil cylinder and are sequentially distributed on the outer wall of the stirring oil cylinder.

[0009] Wherein, the stirring assembly further includes a plurality of stirring bars, and the plurality of stirring bars are all fixedly connected to the stirring block and are sequentially distributed below the stirring block.

[0010] Wherein, the stirring block has a plurality of through holes.

[0011] Among them, the bottom rotating unit includes a support shaft, a cross rotating rod and a plurality of bottom rotating blocks, one end of the support shaft is rotatably connected to the shield machine body and is located on the inner wall of the mud and water bin, the other end of the support shaft is fixedly connected to the cross rotating rod, and the plurality of bottom rotating blocks are all fixedly connected to the cross rotating rod and are distributed in sequence above the cross rotating rod.

[0012] The utility model discloses a mud and water bin with an anti-deposition function. When the shield machine body is running, mud will exist in the mud and water bin. In order to avoid mud deposition, the rotary oil cylinder is started to drive the rotating shaft to rotate, drive the inclined stirring oil cylinder to rotate, and drive the stirring block to rotate at the same time, thereby improving the stirring effect. When the stirring block rotates, it drives the bottom rotating unit to rotate, thereby stirring the bottom of the mud and water bin, further improving the stirring effect. Through the spiral stirring of the stirring oil cylinder, the mud and water bin can be fully covered by relying on one driving source, thus saving energy consumption, and can also stir the bottom of the mud and water bin to effectively avoid deposition.
