[0002] During the construction of building pile foundations, a large amount of mud will be generated in the column holes, so it is necessary to use a high-power self-priming pump to extract the mud to the outside of the column holes. During the drilling process, it is necessary to frequently clean the solid particles in the mud pool, which seriously affects the well drilling efficiency. For example, as shown in a pneumatic pile foundation construction mud liquid-solid rapid separation device with Chinese patent application number CN202222205442.2, the uppermost part of the support is equipped with a stamping structure, and the stamping structure extends to the inside of the support; the power system is installed in the support and is partially located on both sides of the stamping structure; the lower part of the support is provided with an inner tank structure and a slurry inlet and slurry storage structure; the inner tank structure is sleeved in the slurry inlet and slurry storage structure and the two together form a cavity; the lower end of the slurry inlet and slurry storage structure is provided with a slurry outlet structure and it is connected to the slurry inlet and slurry storage structure.

[0003] However, when using a mud separation device to separate the mud in the column hole into solid and liquid, a high-power self-priming pump is used to suck the mud in the column hole into the separation cylinder. The pump pressure is large, which will make the mud flushing ability strong and inconvenient to settle at the bottom of the separation cylinder; in addition, the mud will be adsorbed on the inner wall of the cylinder, resulting in the inability to effectively discharge the liquid in the separation cylinder.

The four fixed blocks 002 are distributed in a circular array at the bottom of the outer wall of the separation cylinder 100. Support legs 001 for supporting the separation cylinder 100 are fixedly installed at the bottom ends of the four fixed blocks 002, so that the separation cylinder 100 can be supported by the four support legs 001.

[0030] The scraping device 200 includes a scraping assembly 220 for scraping the outer wall of the separation assembly 410, and a driving assembly 210 is provided above the scraping assembly 220 for driving the scraping assembly 220 to rotate.

[0031] The driving assembly 210 includes a rotating shaft 212 movably connected to the top of the separation cylinder 100, and the shaft body of the rotating shaft 212 is connected to the top of the separation cylinder 100 through a bearing, so as to facilitate the rotation of the rotating shaft 212; a motor 211 for driving the rotating shaft 212 to rotate is fixedly installed at the top of the rotating shaft 212, and the shaft end of the output shaft of the motor 211 is connected to the top of the rotating shaft 212 through a coupling, so that when the motor 211 is working, it can drive the rotating shaft 212 to rotate; a round table 213 for driving the scraping assembly 220 to rotate is fixedly installed at the bottom of the rotating shaft 212.

[0032] The scraping assembly 220 includes a connecting rod 221 fixedly mounted on the table 213, and a scraper 222 for scraping the inner wall of the separation cylinder 100 is fixedly mounted on the end of the connecting rod 221 away from the table 213, and the scraper 222 is in close contact with the inner wall of the separation cylinder 100; thus, when the rotating shaft 212 drives the table 213 to rotate, the scraper 222 can be made to move in a circular motion around the inner wall of the separation cylinder 100 under the connection action of the connecting rod 221, so that the mud adhered to the inner wall of the separation cylinder 100 can be scraped and cleaned by using the scraper 222; the end of the scraper 222 close to the table 213 is fixedly mounted with a connecting rod 223, and the end of the connecting rod 223 away from the scraper 222 is fixedly mounted with a scraper 224 for scraping the outer wall of the separation assembly 410.

A cone 411 is fixedly mounted at the top of cylinder 412 to buffer the slurry entering separation drum 100. The cone-shaped efficiency structure dissipates energy, reducing the sand flushing capacity of the slurry mixture. Solid particles fall along the conical surface of cone 411 and settle at the bottom of separation drum 100, while the energy-reduced liquid flows into cylinder 412 through the filter holes at the bottom of cylinder 412, thereby achieving solid-liquid separation.

[0035] The discharge assembly 440 includes an annular support plate 1 441 which is mounted on the body of the cylinder 412. An end of the annular support plate 1 441 close to the cylinder 412 is movably connected to an annular support plate 2 442 for cooperating with the annular support plate 1 441 to discharge the solids in the separation cylinder 100. A clip for fixing the annular support plate 1 441 and the annular support plate 2 442 is welded to the bottom ends of the annular support plate 1 441 and the annular support plate 2 442. In order to release the clip to lock the annular support plate 1 441 and the annular support plate 2 442, the annular support plate 1 441 and the annular support plate 2 442 at the bottom of the separation cylinder 100 are opened downward to quickly clean and discharge the solid particles.
