As shown in fig. 1, the present invention provides a slurry preparation and circulation separation system, comprising: a slurry storage tank 6; a mud-sand separator 4 communicated to the mud reserve tank 6 through a mud conveying pipe; the drilling machine 2 is arranged corresponding to a pile foundation casing 1 buried underground, a slurry outlet pipe 3 of the drilling machine 2 is communicated to the mud-sand separator 4, and slurry to be separated is provided for the mud-sand separator 4; a first slurry pump 7 provided between the sand separator 4 and the slurry storage tank 6, for feeding the slurry separated by the sand separator into the slurry storage tank; a second slurry pump 5 provided between the slurry storage tank 6 and the drilling machine 2, for delivering the slurry in the slurry storage tank 6 to the pile casing 1 corresponding to the drilling machine; a slurry preparation tank 8 in which prepared slurry is contained; a third slurry pump 9, which is arranged between the slurry preparation tank 8 and the slurry storage tank 6, and is used for conveying the prepared slurry in the slurry preparation tank to the slurry storage tank.
Specifically, according to the proportion of each component in the slurry, the slurry is prepared in a slurry preparation pool, and the prepared slurry is conveyed to a slurry storage pool by a third slurry pump for standby. When the drilling machine performs drilling operation in the pile foundation casing, slurry is discharged to the mud-sand separator through a slurry outlet pipe of the drilling machine, the mud-sand separator performs purification and separation on the slurry discharged by the drilling machine to remove drilling slag in the slurry discharged by the drilling machine, and the separated slurry is conveyed to a slurry storage pool through a first slurry pump to be stored. And then, according to the requirement of drilling construction of the drilling machine, the second slurry pump is used for conveying the slurry in the slurry storage tank into the pile foundation casing corresponding to the drilling machine so as to supplement the slurry in the pile foundation casing.
Based on the process, the mud preparation and circulation separation system provided by the invention can directly prepare mud, can recycle the mud discharged in the drilling process, and injects the mud into the protective cylinder after purification treatment to supplement the mud required by drilling. In conclusion, the invention meets the requirement of the drilling machine for drilling the slurry based on two modes, improves the flexibility of slurry supply and can effectively reduce the construction cost.
In a preferred embodiment, in the mud preparation and circulation separation system, the mud storage pool 6 is implemented by another pile casing which is buried underground and adjacent to the pile casing.

The slurry preparation pool can be arranged at the periphery of the construction area and is communicated to the slurry storage pool through a slurry conveying pipeline. When the slurry storage pool changes position, the slurry preparation pool can be communicated with a new slurry storage pool by adjusting the position of the slurry supply pipeline. Based on the arrangement, a larger construction area can be radiated by the slurry preparation tank. And the slurry preparation pool is arranged at the periphery of the construction area, so that the drilling construction is not influenced, the two links of slurry preparation and drilling construction are independently realized, and the two links do not interfere with each other.
A bentonite storage area, an additive storage area and fresh water supply equipment are arranged near the mud preparation pool and are used for providing various raw materials for preparing mud. When the slurry is prepared, the bentonite and the admixture can be manually filled into the slurry preparation pool or by using a conveying belt, fresh water is supplied into the slurry preparation pool by using fresh water supply equipment, and the raw materials are uniformly stirred by using an air compressor to prepare the slurry.
In a preferred embodiment, the mud preparation and circulation separation system further comprises a data processing module and a control module, wherein the data processing module is used for determining the net time for the mud reserved in the mud reserve tank to be consumed according to the capacity of the mud reserve tank and the amount of the mud delivered by the mud reserve tank into the pile casing corresponding to the drilling machine; the control module is used for starting the third mud pump to convey the mud prepared in the mud preparation pool to the mud storage pool according to the net consumed time of the mud stored in the mud storage pool.
In order to improve the working efficiency of the system, the data processing module can be used for automatically calculating the net consumed time of the slurry stored in the slurry storage pool, and the control module controls the third slurry pump to automatically convey the prepared slurry to the slurry storage pool according to the net consumed time so as to realize the timely supplement of the slurry. The amount of the mud delivered into the pile foundation casing corresponding to the drilling machine by the mud storage tank can be calculated by the amount of the mud delivered into the pile foundation casing corresponding to the drilling machine by the mud storage tank in unit time and the delivery time, and the amount of the mud delivered into the pile foundation casing corresponding to the drilling machine by the mud storage tank in unit time can be determined by combining the experience of a worker and the working condition of the second mud pump.

In the process of preparing the slurry, after all raw materials are prepared together, the use requirement of the slurry can be met only by standing for a period of time. The standing time is generally 24 hours. Therefore, in order to ensure that the mud preparation tank can provide mud to the mud reserve tank in time, the time for mud preparation is also determined according to the determined net time for mud to be consumed.
