In construction pile foundation engineering, special piling mud separation is usually used for cement separation. The utility model realizes the dehydration of the mud by utilizing the pure mechanical physical principle, thereby facilitating the reuse of water and the transportation of the slurry and slag.

  Separation of piling mud generally consists of a coarse screen module, a desanding module and a desilting module. The flow device is equipped with a double-layer screen as a desanding and desilting cyclone.

  The pile body mud-water separator can effectively improve the quality and efficiency of hole-making, shorten the time of hole cleaning, reduce the cost, and reduce the accident of drill sticking. And from the perspective of environmental protection construction, this kind of equipment also realizes the recycling and reuse of mud at the same time, so that the previous slurry station transportation and dumping treatment are turned to solid-liquid separation of waste slurry, so as to realize muck transportation and treatment. The separation of piling mud can save a lot of mud treatment costs during the construction process, greatly reduce the pollution of construction mud to the environment, and improve the modernization level of civilized and environmentally friendly construction.

  How piling mud separation works.

  The working principle of the utility model drilling rig is that the mud screened by the coarse sieve enters the slurry storage tank (3) of the mud purification device, the slurry pump in the mud purification device pumps the mud downward, and the outlet of the water pump is equipped with a certain amount of energy-storing mud. The sand is injected tangentially from the slurry inlet of the hydrocyclone along the slurry delivery hose, sorted by the hydrocyclone, and discharged from the sand settling nozzle at the lower end of the hydrocyclone, and the sand with a smaller particle diameter is discharged from the fine screen. After being dehydrated and screened by a fine sieve, the dry and finely crushed materials are separated, and the mud screened by a fine sieve is sent back to the slurry storage tank. The treated clean mud enters the middle storage tank through the overflow pipe of the cyclone, and then is sent back to the orifice along the main slurry outlet pipe. During slurry circulation, there is a liquid level buoy between the slurry tank and the slurry tank to keep the liquid level in the slurry storage tank of the slurry purification device constant. When the output slurry in the slurry tank exceeds the amount of slurry supplied, the liquid level buoy will fall with the liquid level.

  Pile driving mud separation is not only used for construction piling mud treatment, piling mud separation is a kind of environmental protection pile foundation auxiliary equipment in modern foundation construction, and can also be used for mud retaining process rotary drilling construction, cycle drilling process pile foundation construction, continuous wall construction , mud-water balance method shield tunneling and mud-water pipe jacking construction and other non-excavation mud-water separation sections.
