Compared with the prior art, the invention has the following beneficial effects:

when the sand-liquid separation device is used, silt needing to be separated enters the first separation bin from the feeding hole, most of the sand is intercepted on the filter screen of the first filter screen plate through the filtering action of the filter screen of the first filter screen plate, the first filter screen plate descends under the action of gravity after the first motor is started, the first filter screen plate cannot move downwards without limit due to the limiting action of the limiting block, the driving plate can be shifted downwards intermittently along with the rotation of the rotating cam, and when the driving plate moves downwards, the first filter screen plate is pried to move upwards due to the lever action, so that the first filter screen plate moves upwards and downwards, and the silt can be promoted to be subjected to solid-liquid separation on the filter screen of the first filter screen plate.

And the first rotating rod and the hinged shaft of the fixed rod are driven to rotate by a third motor. The scraper blade is driven and is moved about, can arrange the one end of first filter screen board with accumulational silt on first filter screen board at the removal in-process, then discharges silt through first mud outlet.

Silt still has some solid particles after first filter screen filters, then continues to carry out more meticulous separation in the second separation storehouse, and liquid passes the filter screen, and solid particle is intercepted on the filter screen of second filter screen, and under the drive of second motor, first connecting rod drives the slider along second filter screen horizontal migration, and in silt that from this goes out the second with on the second filter screen retreats into the second and goes out the mud mouth, realizes the separation of silt.

The sand-mud separator can effectively separate silt, and can simultaneously separate the silt into two stages, namely large-particle sand separated by the first filter screen plate and small-particle sand separated by the second filter screen plate.
