Description

Technical Field

[0001] This utility model relates to the technical field of calcium carbonate processing equipment, and in particular to an ultrafine heavy calcium carbonate grinding and screening structure. Background Technology

[0002] Ultrafine heavy calcium carbonate is a high-value-added non-metallic mineral material prepared from natural calcium carbonate minerals such as calcite and marble through mechanical crushing, grading, and surface modification. Its core performance indicators include particle size distribution, whiteness and purity, and surface properties. To produce ultrafine heavy calcium carbonate, grinding and screening of the calcium carbonate is necessary. While existing grinding and screening structures can process calcium carbonate, they have certain drawbacks. Although the existing equipment continuously grinds, the effective grinding area is only between two relatively rotating grinding structures. Therefore, grinding only begins after calcium carbonate continuously enters the effective grinding area, and the amount of calcium carbonate entering the grinding area is limited, resulting in high grinding difficulty and low grinding efficiency. Furthermore, the discharged calcium carbonate must pass through a filter plate by its own gravity, leading to high material discharge difficulty and low discharge efficiency. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] This utility model provides, for example Figures 1-4 The ultrafine heavy calcium carbonate grinding and screening structure shown includes a housing 1, which includes a housing portion. The housing portion forms a grinding chamber for containing calcium carbonate. A filter plate 18 is fixedly connected to the bottom of the housing portion. A grinding element 3 for grinding calcium carbonate is installed on the housing portion. The grinding element 3 includes a second motor 31, which is fixedly connected to the top of the housing portion. The output end of the second motor 31 is connected to a grinding part for grinding calcium carbonate, which is located inside the grinding chamber. An electric push rod 34 is fixedly connected to the top of the housing portion. A connecting frame 35 is fixedly connected to one side of the second motor 31. The telescopic end of the electric push rod 34 is fixedly connected to one side of the connecting frame 35.

[0016] According to the above technical solution, when grinding and screening calcium carbonate, calcium carbonate raw material is added to the grinding chamber inside the shell. After the calcium carbonate is added, the second motor 31 works, thereby driving the grinding part to rotate. The grinding part grinds the calcium carbonate in the grinding chamber, and the calcium carbonate is ground into calcium carbonate powder. When the grinding part grinds the calcium carbonate, the electric push rod 34 works, thereby driving the connecting frame 35 to move up and down. The connecting frame 35 drives the second motor 31 to move up and down, so that the grinding part moves up and down while grinding the calcium carbonate powder, thereby allowing the grinding part to grind the calcium carbonate faster and improve the production efficiency of calcium carbonate powder. The calcium carbonate powder is discharged through the filter plate 18.

[0017] When the equipment needs to discharge the ground calcium carbonate, in order to improve the discharge efficiency, such as... Figures 1-3As shown, a discharge shell 14 is fixedly connected to the bottom of the shell part, a filter plate 18 is located between the discharge shell 14 and the shell part, an exhaust pipe 15 for discharging gas is fixedly connected to one side of the discharge shell 14, a filter screen 16 is installed inside the exhaust pipe 15, and a one-way valve 17 is fixedly connected to the bottom of the discharge shell 14.

[0018] In this embodiment, before the device produces calcium carbonate powder, a negative pressure suction device is connected to the suction pipe 15. By operating the negative pressure suction device, the suction pipe 15 draws air from the inside of the discharge shell 14, creating a negative pressure inside the discharge shell 14. This causes the filter holes on the filter plate 18 to generate suction, allowing the calcium carbonate powder inside the shell to be discharged from the filter plate 18 more quickly. After the calcium carbonate powder enters the discharge shell 14, it is blocked by the filter screen 16 inside the suction pipe 15. After entering the discharge shell 14, the calcium carbonate powder is discharged through the one-way valve 17.

[0019] Specifically, in one embodiment, regarding the aforementioned housing portion, such as Figures 1-3 As shown, the housing part includes an outer shell 11, and a support foot 13 for supporting itself is fixedly connected to the periphery of the outer shell 11. The bottom of the second motor 31 and the electric push rod 34 are both fixedly connected to the top of the outer shell 11. A feeder 2 for inputting calcium carbonate is fixedly connected to one side of the outer shell 11.

[0020] In this embodiment, when calcium carbonate powder needs to be produced, the outer shell 11 is supported by the support foot 13, and the calcium carbonate raw material is added to the feed member 2. After the calcium carbonate is added, the feed member 2 guides the calcium carbonate to enter the inner shell 11. After the calcium carbonate enters the outer shell 11, the second motor 31 works, thereby driving the grinding part to rotate. The grinding part grinds the calcium carbonate in the grinding chamber, and the calcium carbonate is ground into calcium carbonate powder.

[0021] Furthermore, in this utility model, regarding the aforementioned feed member 2, as follows: Figures 1-3 As shown, the feeding component 2 includes a feeding pipe 21, which is fixedly connected to the outer casing 11 at an incline. The horizontal height of the feeding pipe 21 on the side closer to the outer casing 11 is lower than the horizontal height on the other side. A feeding hopper 24 is fixedly connected to the top of the feeding pipe 21.

[0022] In this embodiment, when adding calcium carbonate, the calcium carbonate is added to the feeding hopper 24, and the feeding hopper 24 guides the calcium carbonate to be transported to the feed pipe 21. The feed pipe 21 then guides the calcium carbonate to be transported to the inside of the outer shell 11, so that the grinding part can easily grind the calcium carbonate.

[0023] Furthermore, in order to facilitate the aggregation of calcium carbonate in the grinding section, such as... Figure 3 As shown, a material guide slope 12 is formed inside the outer shell 11, sloping downwards from the periphery to the center.

[0024] In this embodiment, after the raw material is conveyed into the shell 11, it is guided by the guide slope 12 to allow calcium carbonate to accumulate in the grinding part, making it easier for the grinding part to grind the calcium carbonate.

[0025] Specifically, in one embodiment, regarding the aforementioned grinding portion, as... Figures 1-4 As shown, the grinding part includes a connecting shaft 32, one end of which is connected to the output end of the second motor 31, and the other end is fixedly connected to a grinding head 33.

[0026] In this embodiment, after the calcium carbonate powder enters the shell 11, the second motor 31 works to drive the connecting shaft 32 to rotate, and the connecting shaft 32 drives the grinding head 33 to rotate, so that the grinding head 33 grinds the calcium carbonate and turns it into calcium carbonate powder.

[0027] Furthermore, in this invention, in order to improve the feeding efficiency of calcium carbonate, such as... Figures 1-3 As shown, an auger 23 is rotatably connected inside the feed pipe 21, and a first motor 22 is fixedly connected outside the feed pipe 21. The output end of the first motor 22 is connected to the auger 23.

[0028] In this embodiment, after calcium carbonate is added to the feeding hopper 24, the feeding hopper 24 guides the calcium carbonate to be transported to the feed pipe 21. The first motor 22 works, thereby driving the auger 23 to rotate. The auger 23 drives the calcium carbonate to move along the feed pipe 21, making it easier to transport the calcium carbonate into the shell 11, thereby improving the calcium carbonate addition efficiency.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
