[0002] Calcium carbonate is an inorganic compound with the chemical formula CaCO 3 Calcium carbonate is a main component of limestone, marble, etc. It is usually white crystals, odorless, basically insoluble in water, and easily reacts with acid to release carbon dioxide. It is one of the common substances on the earth and exists in rocks such as aragonite, calcite, chalk, limestone, marble, travertine, etc. It is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.

[0035] The top of the air guide frame 18 is provided with a step, and the air injection holes 20 are evenly distributed on the outer wall of the rotating cylinder 9. The top space and the bottom space of the air guide frame 18 are connected. The rotating cylinder 9 can increase the outflow of air from the air injection holes 20 by rotating using centrifugal force.

[0036] In this embodiment, the air at the bottom of the base 1 enters the interior of the rotating cylinder 9 through the air inlet 6 and the air inlet hole 16. Through the action of the air guide frame 18, the air enters the top of the rotating cylinder 9 through the center position of the air guide frame 18, and the air is ejected through multiple air jet holes 20 on the top edge of the rotating cylinder 9.

In the process of continuous rotation of the rotating cylinder 9, the centrifugal force can be used to accelerate the air flow at the bottom of the rotating cylinder 9, thereby increasing the effect of air collecting calcium carbonate powder.

[0039] In this embodiment, when grinding calcium carbonate, large pieces of calcium carbonate are continuously rotated by the rotating drum 9, which drives the first grinding pins 24, the second grinding pins 25, the third grinding pins 27 and the fourth grinding pins 29 around to rotate. The eccentric rotation of the first eccentric disk 21 generates an impact, so that the first grinding ring 22 continuously hits the upper fixed ring 23 during the rotation. Due to the action of the first eccentric disk 21, multiple eccentric disks and grinding rings, the middle grinding ring 26 and the lower grinding ring 28 are continuously hit, and the calcium carbonate is continuously ground into powder. The grinding concave 31 and the grinding convex 30 at the bottom slide against each other to further grind the calcium carbonate powder, thereby achieving the effect of grinding calcium carbonate using eccentric vibration.

[0040] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 In a preferred embodiment, the auxiliary mechanism includes a first connecting shaft 8 rotatably connected to the other side of the shell 2 near the active bevel gear 17, one end of the first connecting shaft 8 is fixedly connected to the right bevel gear, the other end of the first connecting shaft 8 is an eccentric wheel 46, one side of the grinding cylinder 14 is rotatably connected to a linkage plate 48, a fixed rod is rotatably connected to the inner wall of the feed cylinder 4, one end of the fixed rod is fixedly connected to a rotating plate 45, the other end of the fixed rod is fixedly connected to a connecting plate 43, and a second slide groove 49 is provided on one side of the connecting plate 43.

[0041] The two ends of the connecting plate 43 are fixedly connected with striking blocks 44 respectively, a first slide groove 47 is provided on one side of the bottom end of the linkage plate 48, the top of the linkage plate 48 slides inside the second slide groove 49, and a slide rod is fixedly connected to one side of the eccentric wheel 46, and the slide rod slides inside the first slide groove 47.

[0042] In this embodiment, when the calcium carbonate material enters the interior of the outer shell 2 through the feed barrel 4, large pieces of calcium carbonate material may clog the interior of the feed barrel 4. The first connecting shaft 8 and the eccentric wheel 46 are driven to rotate by the rotating shaft 7, so that the eccentric wheel 46 drives the linkage plate 48 to swing left and right, thereby driving the top of the linkage plate 48 to swing, and the linkage plate 48 drives the connecting plate 43 to swing back and forth, so that the striking block 44 swings back and forth with the connecting plate 43. The striking block 44 continuously strikes large pieces of calcium carbonate, so that the calcium carbonate material is further crushed, preventing large pieces of calcium carbonate from clogging the feed barrel 4, thereby preventing calcium carbonate from clogging the feed barrel 4.

[0043] Working principle: When in use, the base 1 is fixedly connected to the ground, and the calcium carbonate material is introduced into the shell 2 through the feed cylinder 4. After being crushed by the grinding mechanism, the airflow mechanism introduces the bottom air into the screening cylinder 11 through the air guide pipe 12. The air takes away the fully ground calcium carbonate powder inside the grinding mechanism. The air blows the calcium carbonate powder into the screening cylinder 11, and the third connecting shaft 15, the second connecting shaft 13 and the fourth connecting shaft 32 are driven to rotate by starting the motor 5. By driving the rotating column 38 and the fan blades 10 to rotate, suction is generated to make the calcium carbonate powder inside the screening cylinder 11 flow upward with the air, and through the screening of the screening plate 34, the particles that meet the requirements pass through the screening plate 34 into the discharge pipe 3 for collection, and the large particles that do not meet the requirements are discharged. Calcium carbonate falls to the bottom of the screening drum 11, and the ground calcium carbonate powder is screened through the screening effect, which simplifies the processing flow of calcium carbonate after grinding and improves the efficiency of processing calcium carbonate. Large particles of calcium carbonate that do not meet the requirements are accumulated at the bottom of the screening drum 11, and the large particles of calcium carbonate slide to the collecting bucket 36 at the bottom through the guiding effect of the guide seat 35, and the rotating column 38 drives the main gear 39 to rotate, thereby driving the slave gear 40 and the mounting column 37 to rotate, and driving the distributing plate 42 to rotate, so that the large particles of calcium carbonate accumulated at regular intervals will fall back into the interior of the grinding drum 14 from the distributing port 41, clean up the large particles of calcium carbonate in the screening drum 11, and recycle the large particles of calcium carbonate that do not meet the requirements, which has the effect of recycling large particles of calcium carbonate. When the calcium carbonate material enters the shell 2 through the feed barrel 4, large pieces of calcium carbonate material may block the inside of the feed barrel 4. The first connecting shaft 8 and the eccentric wheel 46 are driven to rotate by the rotating shaft 7, so that the eccentric wheel 46 drives the linkage plate 48 to swing left and right, thereby driving the top of the linkage plate 48 to swing, and the linkage plate 48 drives the connecting plate 43 to swing back and forth, so that the striking block 44 swings back and forth with the connecting plate 43, and the striking block 44 continuously strikes the large pieces of calcium carbonate, so that the calcium carbonate material is further crushed, and the large pieces of calcium carbonate are prevented from clogging the feed barrel 4, which has the effect of preventing calcium carbonate from clogging the feed barrel 4. When grinding calcium carbonate, the large pieces of calcium carbonate are continuously rotated by the rotating barrel 9, and the rotating barrel 9 drives the first grinding nails 24, the second grinding nails 25, and the third grinding nails 26 on the surrounding area. The grinding nail 27 and the fourth grinding nail 29 rotate, and the eccentric rotation of the first eccentric disk 21 generates an impact, so that the first grinding ring 22 continuously hits the upper fixed ring 23 during the rotation process. Due to the action of the first eccentric disk 21, multiple eccentric disks and grinding rings, the middle grinding ring 26 and the lower grinding ring 28 are continuously hit, and the calcium carbonate is continuously ground into powder. The grinding concave 31 and the grinding convex 30 at the bottom slide against each other to further grind the calcium carbonate powder, and the effect of grinding calcium carbonate by eccentric vibration is achieved. The air at the bottom of the base 1 enters the interior of the rotating cylinder 9 through the air inlet 6 and the air inlet hole 16, and through the action of the air guide frame 18, the air enters the top of the rotating cylinder 9 through the center position of the air guide frame 18, and the air is ejected through the multiple jet holes 20 on the top edge of the rotating cylinder 9.The air generates eddy currents inside the grinding cylinder 14, and the calcium carbonate powder inside is taken away by the air flow. During the continuous rotation of the rotating cylinder 9, the centrifugal force can be used to accelerate the air flow at the bottom of the rotating cylinder 9, thereby increasing the effect of air collecting the calcium carbonate powder.
