[0002] Wet-process sand making is a water-washing sand-making mode using a wet-process machine. It removes powder by hydraulic means, and through water washing, a large amount of mud powder in the sand grains is removed, so that the powder content of the machine-made sand is relatively low, and finally high-quality construction sand is selected. The dust will also be collected as a by-product. Wet-process sand making can also be equipped with a fine sand recovery device to collect fine sand in sewage. An existing fine sand recovery device, such as a fine sand recovery device with the publication number CN215918160U, includes a recovery box with a feed inlet and a discharge pipe. Inside the recovery box, a first sieve plate and a second sieve plate with different inclination directions are arranged at intervals from top to bottom, and the sieve hole diameters of the first sieve plate and the second sieve plate decrease in sequence; a stirring device includes a stirring shaft vertically arranged in the recovery box and a driving device arranged at the upper end outside the recovery box for driving the stirring shaft to rotate. The stirring shaft passes through the first sieve plate and the second sieve plate in sequence and is rotatably connected to the first sieve plate and the second sieve plate respectively. A plurality of stirring rods are evenly distributed on the outer wall perpendicular to the stirring shaft; a vibration device is arranged inside the stirring shaft and is used to drive the stirring shaft, the first sieve plate and the second sieve plate to vibrate.
[0003] When the above device is in use, a speed-regulating motor drives the stirring rods to rotate to stir the sewage.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0017] Please refer to Figure 1 - Figure 2 , the figure shows a high-efficiency recycling device for ultrafine particles in the circulating water of wet-process mechanism sand of the present invention, including a recycling bin 1.

[0018] A plurality of stirring blades 10 are fixedly connected to the outer walls of the two stirring shafts 2. The rotation of the stirring shaft 2 will drive the plurality of stirring blades 10 to rotate, and the rotation of the stirring blades 10 will stir the sewage.
[0019] The two reciprocating lead screws 3 are respectively threadedly connected to the inner sides of the two moving plates 11. Two impact posts 12 are fixedly connected to the moving plates 11. The inner sides of the moving plates 11 slidably penetrate through the guide rods 13. One end of the guide rod 13 is fixedly connected to the inner wall of the recycling bin 1, and the other end of the guide rod 13 is fixedly connected to the limit block 14. The rotation of the reciprocating lead screw 11 will drive the moving plate 11 to move back and forth along the guide rod 13. The back-and-forth movement of the moving plate 11 will drive the impact post 12 to move back and forth. The back-and-forth movement of the impact post 12 will continuously impact the elastic vibrating plate 18, causing the elastic vibrating plate 18 to vibrate. The vibration of the elastic vibrating plate 18 will cause the sieve plate one 16 and the sieve plate two 17 to vibrate, thereby quickly classifying and screening the sand-water mixture.
[0020] A spiral conveyor blade 15 is fixedly installed on the outer wall of the rotating shaft 4. When the rotating shaft 4 rotates, it will drive the spiral conveyor blade 15 to rotate. The rotation of the spiral conveyor blade 15 can quickly transport the screened wastewater to the drain pipe 20 and then discharge it through the drain pipe 20, avoiding the deposition of wastewater in the recycling tank 1 and affecting the screening effect.
[0021] A first sieve plate 16 and a second sieve plate 17 are fixedly installed on the inner wall of the recycling tank 1. The diameters of the sieve holes of the first sieve plate 16 and the second sieve plate 17 decrease in sequence. Two groups of elastic vibrating plates 18 are fixedly connected to the bottoms of the first sieve plate 16 and the second sieve plate 17. During use, the first sieve plate 16 and the second sieve plate 17 with different sieve hole sizes can be used to classify and screen the sewage.
[0022] The top end of the recycling tank 1 is connected to a feed hopper 19, and the lower end of the outer wall of the recycling tank 1 is connected to a drain pipe 20. A valve is installed on the drain pipe 20. During use, sewage is poured into the inner cavity of the recycling tank 1 through the feed hopper 19, and by opening the valve on the drain pipe 20, the screened wastewater can be discharged.
[0023] Two discharge ports 21 are formed in the recycling tank 1. The bottoms of the inner sides of the two discharge ports 21 are respectively flush with the top ends of the first sieve plate 16 or the second sieve plate 17. A baffle 22 is slidably connected to the inner side of each of the two discharge ports 21.

After the screening is completed, the hydraulic cylinder 23 is started to drive the baffle 22 to move upward, so that the discharge port 21 can be opened, and the classified fine sand can be taken out.
[0024] Working principle of the utility model: When in use, sewage is poured into the inner cavity of the recovery tank 1 through the feed hopper 19. At the same time, the motor 9 is started to drive the rotating rod 7 to rotate. The rotating rod 7 rotates and drives the two groups of stirring shafts 2, the two groups of reciprocating screw rods 3 and a rotating shaft 4 to rotate under the transmission of the first helical gear 5 and the second helical gear 6. The rotation of the stirring shaft 2 drives the rotation of multiple groups of stirring blades 10, and the rotation of the stirring blades 10 stirs the sewage. The rotation of the reciprocating screw rod 11 drives the moving plate 11 to move back and forth along the guide rod 13. The back-and-forth movement of the moving plate 11 drives the impact column 12 to move back and forth. The back-and-forth movement of the impact column 12 continuously impacts the elastic vibration plate 18, causing the elastic vibration plate 18 to vibrate. The vibration of the elastic vibration plate 18 causes the first sieve plate 16 and the second sieve plate 17 to vibrate, so as to quickly classify and screen the sand-water mixture. The rotation of the rotating shaft 4 drives the rotation of the spiral conveying blade 15. The rotation of the spiral conveying blade 15 can quickly convey the screened wastewater to the drain pipe 20 and discharge it through the drain pipe 20, avoiding the deposition of wastewater in the recovery tank 1 and affecting the screening effect. After the screening is completed, the hydraulic cylinder 23 is started to drive the baffle 22 to move upward, so that the discharge port 21 can be opened, and the classified fine sand can be taken out. When taking the material, the motor 9 is started at the same time, so that the impact column 12 moves back and forth continuously to impact the elastic vibration plate 18, causing the elastic vibration plate 18 to vibrate. The vibration of the elastic vibration plate 18 causes the first sieve plate 16 and the second sieve plate 17 to vibrate, so as to accelerate the discharge of the fine sand from the discharge port 21, and then the fine sand is guided by the guide plate 24.
