[0018] See also Figures 1 to 4 The utility model provides a technical solution: a cyclone sand settling tank device, including a chassis, the chassis is composed of a square bin 1 located at the left end and a circular bin 2 located at the right end, the square bin 1 is connected to the circular bin 2, a roller 21 is arranged at the center of the circular bin 2, a stirring rod 22 is arranged horizontally at the bottom of the roller 21, stirring blades 23 are arranged at both ends of the stirring rod 22, a reduction motor 24 is arranged at the top of the roller 21, and the top of the roller 21 is connected to the output end of the reduction motor 24, a feed port 25 and a water inlet 26 are arranged on the circular bin 2, and the feed port 25 and the water inlet 26 are located on the same side of the circular bin 2, a sand discharge port 27 is arranged below the circular bin 2, and a discharge port 11 is arranged below the square bin 1, the height of the sand discharge port 27 is lower than the position of the discharge port 11, and it is easy to make the mud and sand sink and pull away from other light objects or floating objects. A baffle 12 is arranged above the discharge port 11 to prevent mud and sand from flowing to the discharge port 11, and the work between multiple hole positions does not affect each other.
[0019] The top end of the roller 21 contacts the inner wall of the top layer of the circular bin 2 , and the bottom end of the roller 21 is located at the lower end of the circular bin 2 and does not contact the bottom of the circular bin 2 , leaving a certain space for the mud and sand reaction at the bottom of the circular bin 2 .
[0020] like Figure 2 As shown, the part where the sand discharge port 27 contacts the circular bin 2 is hollowed out, and the hollowed-out part is tilted downward (1A) toward the sand discharge port 27 to facilitate the sliding of mud and sand.
[0021] like Figure 4 As shown, the portion where the discharge port 11 contacts the square bin 1 is hollowed out, and the hollowed-out portion is tilted downward toward the discharge port 11 (2B), so as to facilitate the falling of other debris that is lighter than mud and sand.
[0022] A cover plate 13 is provided on the upper surface of the square bin 1, and a plurality of observation ports 28 are provided on the upper surface of the circular bin 2, so as to facilitate cleaning and observation of the interior of the device.

The stirring rod 22 is detachably connected to the bottom of the roller 21. The stirring rod 22 is sleeved on the roller 21 through a detachable sleeve. When the stirring rod 22 or the stirring blade 23 is damaged, it is easy to disassemble and replace.
[0024] In the utility model, the working steps of the device are as follows:
[0025] Water is injected from the water inlet 26. When a certain amount of water is injected, the reduction motor 24 is started to drive the roller 21 to rotate, and the mixed garbage is put into the circular bin 2 from the feed port 25. The stirring rod 22 and the stirring blade 23 on the roller 21 stir the debris, so that the mud and sand sink more and more and fall from the sand discharge port 27. The suspended matter moves to the discharge port 11 under the action of the water flow and is discharged from the discharge port 11, thereby achieving the purpose of sand separation and discharge.
[0026] At the same time, the feed port 25 is located on one side of the water inlet 26, so that the debris can be impacted by the water flow entering the water inlet 26 and the water flow pushed by the stirring rod 22 at the same time, and the debris is impacted for a longer time. If it is set on the opposite side of the circular bin 2, this effect cannot be achieved.
