DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Embodiment one

[0022] Please refer to Figures 1-4 The utility model provides a kind of calcium carbonate processing grinding equipment, including bin 1, bin 1 top side is equipped with feed inlet 2, the lower end of the inner cavity of feed inlet 2 is equipped with first distributor 3, the upper end of the inner cavity of feed inlet 2 is equipped with connecting pipe 4, first distributor 3 is rotatably connected with second distributor 5 compatible with it, and second distributor 5 can be connected with the output end of motor 6 by transmission structure.

[0023] In the embodiment, connecting pipe 4 can be used to hold material, which facilitates the feeding of raw materials from feed inlet 2. First distributor 3 is provided with two groups of through holes, and second distributor 5 is also provided with two groups of through holes. When the two groups of through holes coincide, the flow rate is maximum, and vice versa. By starting motor 6 and cooperating with the transmission structure, second distributor 5 can be driven to rotate, so that the size of feed inlet 2 gradually changes during the discharging process. First, it gradually increases to accelerate the outflow of materials, and then it gradually decreases to slow down the outflow speed of materials, forming a circulating discharging effect. Compared with continuous discharging, there is a certain buffer period, which can prevent the accumulation of raw materials in the grinding area, improve the grinding efficiency, and does not affect the grinding purity.

[0024] Please refer to Figures 1-4 As shown in the figure, the transmission structure includes first gear 7 and second gear 8. First gear 7 is integrally formed on the outer wall of second distributor 5, and first gear 7 is engaged with second gear 8. Second gear 8 is sleeved on the outside of the output shaft of motor 6. Motor 6 is installed on the top of bin 1, and its output shaft can be connected with grinding cone 9. Grinding cone 9 can cooperate with grinding seat 10 arranged at the lower end of the inner cavity of bin 1 to realize grinding. Grinding seat 10 is integrally formed with bin 1. Three groups of support members 11 are installed at the bottom end of bin 1 at equal intervals.

[0025] In the embodiment, the motor 6 is started to drive the second gear 8 to rotate, so as to drive the first gear 7 to rotate, and then drive the second distributor 5 to rotate, and the grinding cone 9 connected with the output shaft of the motor 6 also rotates to grind the raw material together with the grinding seat 10.

[0026] Please refer to Figures 1-4 The bottom end of the grinding seat 10 is provided with a discharge port 12, and a collecting device is arranged below the discharge port 12 to collect the material. The collecting device includes collecting frames 13 and handles 14. Two groups of collecting frames 13 are arranged in a stacked manner. Each group of collecting frames 13 is provided with a group of handles 14 on both sides. The collecting frames 13 are in sliding connection with limiting seats 15 arranged at the bottom end of the material bin 1. The two groups of limiting seats 15 are integrally formed with sliding blocks 16 on both sides of each group of collecting frames 13. The sliding blocks 16 are in sliding connection with the limiting seats 15.

[0027] In the embodiment, the ground calcium carbonate is discharged through the discharge port 12 and then collected by the collecting device. Since the traditional collecting method only provides one group of collecting frames 13 to collect the material, when the collecting frames 13 are filled with calcium carbonate, they need to be removed from the equipment and replaced with empty frames. If the equipment only provides one group of collecting frames 13, the replacement process needs to be stopped, which affects the production efficiency. During the replacement process, attention needs to be paid to avoid the calcium carbonate from spilling and polluting, which increases the complexity and time cost of the operation. In addition, after a long time of use, some impurities may accumulate in the collecting frames 13, which need to be cleaned and maintained. If there is only one group of collecting frames 13, the cleaning process needs to be stopped, which also affects the production efficiency. Therefore, two groups of collecting frames 13 are arranged in a stacked manner. During use, one group of collecting frames 13 can be pulled out without affecting the other group of collecting frames 13 to continue collecting the material, so that the production efficiency is improved. The sliding blocks 16 integrally formed with the collecting frames 13 are in sliding connection with the limiting seats 15, which can improve the stability of sliding. In addition, the handles 14 are installed to facilitate the taking and placing of the collecting frames 13.
