[0025] In the utility model, the calcium stone raw material cleaning and screening device generates vibration after being started, and the user transports the calcium stone to the top of the device, and the calcium stone preferentially falls on the screening column 4, and the screening column 4 has a certain slope. Through the vibration of the device, the screening column 4 will perform preliminary screening on the calcium stone, and the calcium stone that does not meet the conditions will be affected by the high-frequency vibration and gravity, and directly enter the next stage of screening, and the calcium stone that meets the conditions will fall on the screen 7 for secondary screening. The gap of the screening column 4 will be slightly larger than the gap of the grid on the screen 7, so as to ensure that double screening can be carried out at the same time, thereby increasing the screening efficiency, and the calcium stone can be rinsed with clean water during the screening.

[0026] After screening is completed, the calcium stone falls through the transition chamber 8 into the discharge pipe 9. The discharge pipe 9 has a certain slope and vibrates at the same frequency as the device to make the screened calcium stone move forward. The water and sediment carried by the calcium stone are separated after filtering through the calcium stone filter 17. The water and sediment enter the sand outlet pipe 20. The water and sediment are separated after filtering through the dust filter 18. The water enters the wastewater pipe 21. The water discharged through the wastewater pipe 21 can be collected and reused.
