[0029] Embodiment 1: As shown in the accompanying drawings, a multi-stage screening device for calcium carbonate production includes a frame 1 and a guide plate 2, wherein the guide plate 2 is obliquely arranged in the frame 1, the frame 1 is a double-cavity structure, a plurality of discharge ports 3 are opened on the frame 1, and the tops of the discharge ports 3 are all inclined surfaces, and a screening assembly is also included, wherein the screening assembly is used to screen calcium carbonate.

[0030] In the present embodiment, specifically, the sub-screening assembly comprises a plurality of frames 4, a plurality of rotating shafts 5, a plurality of telescopic fixed blocks 6, a plurality of thin rods 7, a plurality of fixed plates 8, a plurality of bidirectional threaded rods 9, a vibration motor 10, a control panel 101 and a driving assembly, wherein the plurality of frames 4 are rotatably connected to the frame 4 via the rotating shaft 5, the plurality of telescopic fixed blocks 6 are respectively fixed to adjacent frames 4, the plurality of thin rods 7 are respectively fixed between the relative telescopic fixed blocks 6, the plurality of fixed plates 8 are respectively fixed to adjacent telescopic fixed blocks 6, the plurality of bidirectional threaded rods 9 are respectively rotatably connected to adjacent fixed plates 8, the plurality of bidirectional threaded rods 9 are respectively located in adjacent telescopic fixed blocks 6, the vibration motor 10 is fixed to the inside of the frame 1 by bolts, the control panel 101 is mounted on the outer wall of the frame 1, the vibration motor 10 is electrically connected to the control panel 101, and the driving assembly is used to drive the bidirectional threaded rods 9 to rotate and drive the telescopic fixed block 6 to perform telescopic adjustment. The driving assembly includes a plurality of large bevel gears 11, a plurality of small bevel gears 12, a plurality of first rotating shafts 13, a plurality of second rotating shafts 14, a plurality of transmission assemblies 15, a motor frame 16, a servo motor 17 and a protective cover 18. The plurality of large bevel gears 11 are respectively keyed to the middle of the adjacent two-way threaded rods 9, the plurality of first rotating shafts 13 are all rotatably connected to one side of the frame 4 close to the large bevel gear 11, the plurality of small bevel gears 12 are respectively keyed to the adjacent first rotating shafts 13, and the plurality of second rotating shafts 14 are rotatably connected to the frame 4. At the bottom, the plurality of transmission components 15 are respectively connected between the adjacent first rotating shaft 13 and the second rotating shaft 14, the motor frame 16 is fixedly connected to the bottom of the frame 4, the servo motor 17 is fixedly connected in the motor frame 16, the output shaft of the servo motor 17 is connected to the adjacent first rotating shaft 13 through a coupling, the servo motor 17 is electrically connected to the control panel 101, the protective cover 18 is fixedly connected to the bottom of the frame 4, and the transmission components 15, the motor frame 16 and the servo motor 17 are all located in the protective cover 18.

[0031] Furthermore, it also includes a guide assembly, which is used to guide the calcium carbonate. Specifically, the guide assembly includes a plurality of guide blocks 19, a plurality of guide plates 20 and a collection frame 21, wherein the plurality of guide blocks 19 are respectively fixed to the top of the adjacent frames 4, the plurality of guide plates 20 are respectively fixed to the inside of the adjacent frames 4, and the collection frame 21 is placed in the lower part of the frame body 1.

[0032] It should be noted that there are three frames 4, the two-way threaded rod 9 has multiple threads, the threads of the two-way threaded rod 9 are gradually denser from the inside to the outside, and the telescopic fixed blocks 6 in the same frame 4 are symmetrically arranged. There are seven transmission components 15, each of which is connected to one of the first rotating shafts 13 and one of the second rotating shafts 14. The top of the guide block 19 has two inclined guide surfaces, which can guide calcium carbonate.

[0033] In the above technical solution, before screening, the servo motor 17 is started by controlling the control panel 101, and the output shaft of the servo motor 17 drives the corresponding first rotating shaft 13 to rotate, and then drives the remaining first rotating shafts 13 and second rotating shafts 14 to rotate through the transmission assembly 15, thereby driving the small bevel gear 12 to rotate, so that the small bevel gear 12 drives the large bevel gear 11 to rotate, and then the large bevel gear 11 drives the bidirectional threaded rod 9 to rotate, thereby driving the telescopic fixed block 6 to perform telescopic movement adjustment, and then driving the thin rod 7 to perform movement adjustment, so that the aperture size of the staggered thin rod 7 can be adjusted, so as to meet the needs of different diameters. The calcium carbonate that needs to be screened is simple to operate and has high practicality. The apertures divided by the thin rods 7 in the three frames 4 are adjusted to different sizes, so that the aperture of the screening layer on the upper right is smaller than the aperture of the screening layer on the left middle side, and the aperture of the screening layer on the lower right is smaller than the aperture of the screening layer on the upper right side, which is convenient for multi-stage screening of calcium carbonate. After the adjustment is completed, the servo motor 17 is controlled to stop; then the vibration motor 10 is controlled to start through the control panel 101, and then the crushed calcium carbonate that needs to be screened is poured into the frame 1 for screening. When feeding, the guide plate 2 guides the calcium carbonate, and the guide block 19 can guide the calcium carbonate so that the calcium carbonate can fall into the fine mesh of the frame 4 on the upper right side. The frame 4 is tilted, and the calcium carbonate is screened while being screened along the tilted direction of the frame 4. During this period, the guide plate 20 can guide the calcium carbonate to prevent the calcium carbonate from being stuck in the frame 4 and unable to enter the next frame 4. The medium-sized calcium carbonate is screened to the frame 4 on the lower right side for secondary screening, and then the smaller-sized calcium carbonate is further screened out. The medium-sized calcium carbonate is discharged and collected, and the larger-sized calcium carbonate is withdrawn to the frame 4 on the left side for secondary screening, and the larger-sized calcium carbonate is further screened out. Calcium is screened, and the screened calcium carbonate falls into the collecting frame 21 for collection. After the screening is completed, four sizes of calcium carbonate can be obtained. The screening effect is good, and it is convenient to use calcium carbonate of different sizes for production and use. After the end, when it is necessary to screen the next batch of calcium carbonate of different sizes, the servo motor 17 is started by the control panel 101 to control the thin rod 7 to move and adjust the aperture. During the adjustment period, the mutual friction between the thin rods 7 can achieve a self-cleaning effect, and the thin rod 7 moves to adjust the aperture size, which can make the calcium carbonate stuck between the thin rods 7 fall off by itself. In this way, there is no need to manually clean the thin rod 7 again, which reduces the operation trouble and improves the work efficiency.
