Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate sorting technology, and in particular to a calcium carbonate grading and sorting device. Background Technology

[0002] Calcium carbonate is a common inorganic compound with a wide range of applications. It is an important building material and plays an indispensable role in many industrial sectors, including coatings, plastics, rubber, papermaking, pharmaceuticals, and food. Different applications have different requirements for the particle size, purity, and whiteness of calcium carbonate. For example, calcium carbonate used in papermaking typically requires a finer particle size to improve the smoothness and whiteness of the paper; while calcium carbonate used as a rubber filler has specific requirements for particle size distribution and surface properties to improve the performance of the rubber. To meet the specific needs of various fields, calcium carbonate needs to be graded and sorted to obtain products with different particle size ranges and qualities.

[0003] A search revealed Chinese patent number CN213887055U. This utility model provides a calcium carbonate grading and sorting device, which relates to the field of calcium carbonate equipment technology. It includes a device body, a rotating nozzle base and a support block, with a feed hopper embedded at the top of the device body. Equipped with a vibration motor, when the calcium carbonate to be screened enters the main body of the device through the feed hopper, it falls above the filter plate. The vibration motor starts, causing the filter plate to vibrate, and the filter plate will vibrate and float due to the elasticity of the first spring, achieving rapid screening of the calcium carbonate above the filter plate. The filter plate has different sized filter holes, allowing calcium carbonate of different sizes to pass through the corresponding filter holes for screening. At the same time, the calcium carbonate that passes through different filter holes is separated by a separator plate, so that the three different sizes of calcium carbonate fall above the guide plate and slide down to the corresponding discharge port to flow out, achieving rapid screening. However, the sorting equipment may malfunction due to the floating calcium carbonate particles during the screening process. Therefore, a relatively sealed space is required to ensure that the particles fly out. Moreover, under high-intensity operation, the finished product bin may experience problems such as the inability to discharge the undersize material and the accumulation of fine powder under the screen.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See attached document Figure 1 - Appendix Figure 5This utility model provides an embodiment of a calcium carbonate grading and sorting device, comprising a base 1, a fixed platform 2 11 fixedly connected to one side of the base 1, a rotating rod 2 10 rotatably mounted inside the fixed platform 2 11, eccentric wheels 9 fixedly connected to both ends of the rotating rod 2 10, a swing arm 7 fixedly mounted on each of the two eccentric wheels 9, a rotating rod 1 6 fixedly connected to one end of the swing arm 7, a mounting platform 1 5 rotatably connected to the outside of the rotating rod 1 6, one end of the rotating rod 1 6 connected to the output shaft of a motor 8 via a coupling, four fixed blocks 27 symmetrically fixedly connected to both ends of the base 1, a silicone plate 3 threadedly connected to one side of each of the four fixed blocks 27, a nut 4 threadedly connected to both the fixed blocks 27 and the silicone plate 3, a fixed block 1 2 threadedly connected to one side of the upper end of each of the silicone plate 3, and a filter screen 12 fixedly connected to one end of the fixed block 1 2.

[0024] The base 1 serves to fix the entire device. The rotating rod 10 is fixed by the fixed platform 11. Both ends of the rotating rod 10 are fixedly connected to the eccentric wheel 9, which is then fixedly installed by the swing arm 7. It is connected to the rotating rod 6 at the other end to form a left-right swinging screening device. The rotating rod 6 is fixed to the screening device by passing through the inside of the mounting platform 5. The other end of the mounting platform 5 is connected to the filter screen 12. The filter screen 12 is made of copper alloy, which has good flexibility, smooth wire surface, and is not easy to stick to particles, making it suitable for fine powder screening. The motor 8 provides power to the entire screening device, and its output end is connected to the rotating rod 6. The silicone plate 3 increases the stability of the entire screening device and fixes the left-right swing amplitude.

[0025] A drawer cabinet 13 is fixedly connected to the lower end of the filter 12. Slide grooves 18 are provided at both ends of the interior of the drawer cabinet 13. A drawer 14 is slidably connected inside the drawer cabinet 13. Slide rails 16 are fixedly connected to both ends of the drawer 14. A slot 17 is provided on the front side of one end of the slide rail 16. A fixed platform 19 is fixedly connected to the exterior of the drawer cabinet 13. A button 24 is installed on the upper end of the fixed platform 19. A spring 20 is provided inside the fixed platform 19. A slider 21 is fixedly connected to one end of the spring 20. Slide rods 22 are slidably connected to both sides of the slider 21. A pin 23 is fixedly connected to the lower end of the slider 21. The pin 23 passes through the interior of the drawer cabinet 13 and is inserted into the slot 17 on the slide rail 16. A mounting platform 26 is fixedly connected to the bottom of the motor 8. A collection platform 25 is fixedly installed on the upper end of the filter 12. One end of the spring 20 is fixedly connected to one side of the slider 21. The other end of the spring 20 is fixedly connected to the inner wall of the fixed platform 19. A handle 15 is fixedly connected to the exterior of the drawer 14.

[0026] Drawer 14 and drawer cabinet 13 work together to store the filtered calcium carbonate. The calcium carbonate is pulled out or pulled in through the sliding groove 18 inside the drawer cabinet 13 and the slide rail 16 on the drawer 14. A fixed platform 19 is provided on the outside of the drawer cabinet 13, and a fixing device is provided inside. Through the interaction of the spring 20 and the slider 21 inside, the latch 23 moves left and right, thereby fixing the drawer 14.

[0027] Working principle: First, the operator turns on the motor 8, causing the output end of the motor 8 to drive the rotating rod 6. The two ends of the rotating rod 6 are fixed to the swing arm 7, and the other end of the swing arm 7 is connected to the eccentric wheel 9. The eccentric wheel 9 is fixed on the rotating rod 10. Therefore, the entire device swings left and right under the action of the motor 8. At this time, the calcium carbonate to be screened is poured into the collection table 25. The calcium carbonate is screened through the filter screen 12 due to the swing. The required calcium carbonate enters the drawer below through the filter screen, thus solving the problem of poor material flow caused by the formation of agglomerates due to high humidity or fine particle size.

[0028] Because the daily screening process in daily use can cause the storage bin to accumulate, we have solved the problem of the finished product bin being full and causing the screened material to accumulate under the screen when it is too full. This is because if the screening is too full, you can pull the latch 23 by pressing button 24 and then pull the handle 15 to pull out the drawer 14 and pour out the screened calcium carbonate.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
