This structure screens calcium carbonate through the combination of rotational screening and vibration screening, increasing the stability of equipment use. The overall volume of the equipment is small, making it more suitable for screening small batches of calcium carbonate and easier to clean;
[0021] Further, the rear side of the first filter cylinder 5 is closed and is provided with three pressing blocks 9 at the rear side, three pressing grooves 10 are opened at the rear end of the second filter cylinder 6, the pressing blocks 9 are clamped in the pressing grooves 10, a sealing block 11 is fixedly mounted at the upper rear end of the first filter cylinder 5, a discharge port 12 is opened at the rear side of the second filter cylinder 6, and the sealing block 11 is inserted into the discharge port 12. This structure enables the first filter cylinder 5 and the second filter cylinder 6 to be assembled, and after screening, the first filter cylinder 5 and the second filter cylinder 6 can be staggered to load materials separately.
[0022] Further, limiting blocks 13 are fixedly mounted at the upper and lower ends of the rear side of the second filter cylinder 6, limiting holes 14 are opened at the central positions of the limiting blocks 13, limiting grooves 15 are opened on the turntable 4, insertion holes 16 are opened on the turntable 4, the positions of the insertion holes 16 are opposite to the positions of the limiting holes 14, slots 19 are opened on the sealing cover 8, the positions of the slots 19 are opposite to the positions of the insertion holes 16, insertion rods 17 are inserted into the insertion holes 16, threads are opened at the lower ends of the insertion rods 17, and screw sleeves 18 are sleeved on the lower ends of the insertion rods 17. This structure enables the first filter cylinder 5 and the second filter cylinder 6 to be disassembled, increasing the convenience during equipment cleaning and feeding, and increasing the convenience of equipment use.
[0023] Further, the discharge mechanism includes a collection ring 20, the collection ring 20 is fixedly mounted on the turntable 4, the collection ring 20 is in close fit with the third filter cylinder 7, a guiding block 21 is arranged in the collection ring 20, and a discharge groove 22 is opened at the lower end of the collection ring 20. This structure enables the finest calcium carbonate to be stored in the collection ring 20 and can be conveniently discharged from the discharge groove 22 when taking materials.
[0024] Further, a vibration block 23 is arranged on the front side array of the slot 19, and an elastic telescopic rod 24 is fixedly installed on the front side of the mounting frame 1. The upper end of the elastic telescopic rod 24 is fixedly installed with a resisting block 25. The elastic telescopic rod 24 is composed of a sleeve rod, a piston rod and a spring. The piston block end of the piston rod moves within the sleeve rod. The spring is arranged within the sleeve rod and abuts against the end of the piston rod. The sleeve rod is fixedly connected to the mounting frame 1, and the piston rod is fixedly connected to the resisting block 25. The resisting block 25 is in contact with the vibration block 23. This structure enables the device to be vibrated during rotation, reducing the possibility of the device being blocked during use and improving the screening efficiency of the device.
[0025] Further, the limiting mechanism includes a loading cylinder 26. The loading cylinder 26 is fixedly installed at the upper end of the mounting frame 1. A movable rod 27 is movably installed within the loading cylinder 26. A cross-shaped block 28 is fixedly installed at the end of the movable rod 27. A cross-shaped groove 29 is formed on one side of the turntable 4. The cross-shaped block 28 is inserted into the cross-shaped groove 29. A spring 30 is sleeved on the movable rod 27. A slider 31 is fixedly installed on the cross-shaped block 28. A sliding groove 32 is formed within the loading cylinder 26. The slider 31 moves within the sliding groove 32. This structure enables the mounting disc 2 to rotate and be limited after rotation, making it easier to take out the screened materials.
[0026] Working principle: During use, pull out the movable rod 27 outwards. At this time, the cross-shaped block 28 disengages from the cross-shaped groove 29 and compresses the spring 30. The slider 31 moves within the sliding groove 32. At this time, the mounting disc 2 can rotate. Rotate the mounting disc 2 to a horizontal state, add calcium carbonate into the first filter cylinder 5, then close the sealing cover 8 on the collecting ring 20 so that the slot 19 is opposite to the jack 16, then insert the insertion rod 17 into the jack 16 and fix it with the screw sleeve 18. After completion, rotate the mounting disc 2 to a vertical state, start the motor 3 to make the turntable 4 rotate, and start screening. The resisting block 25 continuously collides with the vibration block 23 under the action of the elastic telescopic rod 24 to achieve vibration. After screening, rotate the mounting disc 2 to a horizontal state, then take out the sealing cover 8 and pull out the first filter cylinder 5. At this time, the second filter cylinder 6 will be taken out together. Then stagger the first filter cylinder 5 and the second filter cylinder 6. At this time, the sealing block 11 disengages from the discharge port 12, and the calcium carbonate in the second filter cylinder 6 will leak out from the discharge port 12. Then pour out the calcium carbonate in the first filter cylinder 5, and then vertically install the mounting disc 2 again, and it is necessary to ensure that the discharge groove 22 is on the upper side, discharge the calcium carbonate in the third filter cylinder 7, and then rotate the turntable 4 so that the discharge groove 22 is on the lower side. At this time, the calcium carbonate in the discharge groove 22 is discharged under the guidance of the guiding block 21. The above is all the working principle of the present invention.
