It is a common substance on the earth, existing in rocks such as aragonite, calcite, chalk, limestone, marble, travertine, etc., and is also the main component of animal bones or shells. Calcium carbonate is an important building material and has a wide range of uses in industry.

Therefore, the calcium carbonate is crushed and then fully ground and chopped, and the calcium carbonate that meets the specifications and the heat can be discharged through the discharge pipe.

[0004] When grinding calcium carbonate, the existing calcium carbonate high-efficiency grinding equipment first adds the calcium carbonate block into the grinding chamber, grinds it by the first grinding ball and the second grinding ball, and simultaneously cuts the calcium carbonate by the first blade and the second blade. However, in the process of grinding calcium carbonate, the existing device needs to be ground in the grinding chamber or on the grinding disc, so the grinding equipment needs to be set on both sides of the corresponding grinding chamber or grinding disc, resulting in a limited number of grinding rollers, which reduces the processing efficiency of the device. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the existing high-efficiency grinding equipment for calcium carbonate reduces the grinding efficiency of the device due to the limited number of grinding rollers when grinding calcium carbonate. The present application provides a high-efficiency grinding equipment for producing ultrafine calcium carbonate.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A high-efficiency grinding device for producing ultrafine calcium carbonate comprises a base, a bracket fixedly connected to the base, an outer wall fixedly connected to the bracket, an inner wall fixedly connected inside the outer wall, a grinding disc arranged in the inner wall, a discharge pipe fixedly connected to the outer wall, a feed pipe fixedly connected to the outer wall, a grinding structure arranged in the inner wall, and a screening structure arranged between the inner wall and the outer wall.

[0008] By adopting the above technical scheme, when the device is used to grind calcium carbonate, the calcium carbonate raw material is first put into the inner wall through the feed pipe, and then the grinding disc is started to rotate through the grinding structure to bring the raw material into the grinding structure between the inner wall and the grinding disc for grinding, and by arranging multiple layers on the grinding disc, each layer has multiple grinding rollers to grind the raw material multiple times, so that the device has a stronger grinding effect on the raw material and the ground product is more delicate. At the same time, the raw material also moves downward along the edge of the grinding disc to the bottom of the outer wall, and is screened by the screening structure, and then the raw material that meets the standards is discharged through the discharge pipe, which facilitates the device to grind the processed raw materials to the same standard.

[0009] Furthermore, the grinding structure includes a driving motor fixedly connected to the bracket, an active roller is fixedly connected to the output end of the driving motor, the active roller is rotatably connected to the base, a driven roller is rotatably connected to the base, belts are sleeved on the active roller and the driven roller, and the driven roller is fixedly connected to the grinding disc.

[0010] By adopting the above technical solution, the driving motor is started to drive the active roller to rotate, thereby driving the belt to rotate the driven roller, and the grinding disc is rotated to grind the raw material.

[0011] Furthermore, the grinding disc is fixedly connected to a fixed shaft, the lower end of the fixed shaft is rotatably connected to grinding roller one, the upper end of the fixed shaft is rotatably connected to grinding roller two, the inner wall is fixedly connected to a grinding wall, the grinding wall is provided with a grinding groove, and the grinding groove is adapted to grinding roller one and grinding roller two.

[0013] Furthermore, a conical block is fixedly connected to the upper end of the grinding disc, a semicircular block is fixedly connected to the top end of the conical block, and an inclined plate is fixedly connected to the grinding plate.

[0014] By adopting the above technical solution, when the raw material falls into the inner wall, the raw material is guided by the conical block and the inclined plate to move into the gap between the grinding disc and the grinding wall, so that the loading efficiency of the device is faster.

[0015] Furthermore, a separation motor is fixedly connected to the outer side wall, a grid impeller is fixedly connected to the output end of the separation motor, and the grid impeller is located in the discharge pipe.

[0016] By adopting the above technical solution, the separation motor drives the grid impeller to rotate, thereby screening the finished products in the air flow, so that larger particles are knocked down to the grinding disc for re-grinding, which enables the device to screen the finished products by itself.

[0018] By adopting the above technical solution, the finished product falls on the feeding plate due to gravity, and is thrown onto the annular plate as the feeding plate rotates. At the same time, air is sucked in from the outside of the device through the discharge pipe, driving the air flow in from the air inlet to drive the finished product to rise upward along the feeding trough.

[0019] Furthermore, an arc-shaped top plate is fixedly connected to the inner top of the outer side wall, a screening groove is opened at the center of the arc-shaped top plate, and the screening groove is adapted to the grid impeller.

[0021] Furthermore, the feed pipe is fixedly connected to the inner side wall, and the end of the feed pipe corresponds horizontally to the conical block and the inclined plate.

[0022] By adopting the above technical solution, the feed pipe is passed through the inner wall and the outer wall so that its end is level with the conical block and the inclined plate, which facilitates the device to feed the raw materials into the grinding tank for grinding, speeds up the feeding efficiency of the device, and thus improves the processing efficiency of the device.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when the raw material falls into the inner wall, the raw material is guided by the conical block and the inclined plate to move into the gap between the grinding disc and the grinding wall, so that the loading efficiency of the device is faster, and at the same time, the driving motor is started to drive the active roller to rotate, thereby driving the belt to rotate the driven roller, so that the grinding disc rotates, and the raw material enters the grinding groove during the falling process, and is ground by the grinding roller 1 and the grinding roller 2 that rotate with the rotation of the grinding disc, so that calcium carbonate can be ground by the grinding rollers that have passed through multiple times during the grinding process, so that the finished product ground by the device is more delicate, and the grinding efficiency of the device is improved by the cooperation of the grinding disc and multiple grinding rollers 1 and 2.

[0025] 2. In the present application, the finished product after grinding falls on the feeding plate due to gravity, and is thrown onto the annular plate as the feeding plate rotates. At the same time, air is sucked in from the outside of the device through the discharge pipe, driving the air flow to enter from the air inlet and driving the finished product to be lifted upward along the feeding trough. The finished product is more easily entered into the discharge pipe due to the influence of the arc-shaped top plate. When the finished product is drawn out from the discharge pipe, the separation motor drives the grid impeller to rotate, thereby screening the finished product in the air flow, so that larger particles are knocked onto the grinding disc for re-grinding. This enables the device to screen the finished products by itself, improves the quality control ability of the device in production, allows substandard raw materials to be re-grinded, and improves the quality of the finished products of the device.

[0035] When the device is used to grind calcium carbonate, the calcium carbonate raw material is first put into the inner wall 8 through the feed pipe 26, and then the grinding disc 10 is started to rotate through the grinding structure to bring the raw material into the grinding structure between the inner wall 8 and the grinding disc 10 for grinding. In addition, multiple layers of grinding rollers are arranged on the grinding disc 10, and the raw material is ground multiple times, so that the device has a stronger grinding effect on the raw material and the ground product is more delicate. At the same time, the raw material also moves downward along the edge of the grinding disc 10 to the bottom of the outer wall 7, and is screened by the screening structure. Then, the raw material that meets the standards is discharged through the discharge pipe 11, which facilitates the device to grind the processed raw materials to the same standard.

A fixed shaft 20 is fixedly connected to the grinding disc 10, a grinding roller 18 is rotatably connected to the lower end of the fixed shaft 20, a grinding roller 2 19 is rotatably connected to the upper end of the fixed shaft 20, a grinding wall 9 is fixedly connected to the inner wall of the inner side wall 8, a grinding groove 21 is provided on the grinding wall 9, and the grinding groove 21 is adapted to the grinding roller 18 and the grinding roller 2 19. A conical block 14 is fixedly connected to the upper end of the grinding disc 10, a semicircular block 15 is fixedly connected to the top of the conical block 14, and an inclined plate 16 is fixedly connected to the grinding plate.

[0037] When the raw material falls into the inner wall 8, the raw material is guided by the conical block 14 and the inclined plate 16 to move into the gap between the grinding disc 10 and the grinding wall 9, so that the feeding efficiency of the device is faster, and at the same time, the driving motor 3 is started to drive the active roller 4 to rotate, thereby driving the belt 5 to rotate the driven roller 6, so that the grinding disc 10 is rotated, and the raw material enters the grinding groove 21 during the falling process, and is ground by the grinding roller 18 and the grinding roller 2 19 that rotate with the rotation of the grinding disc 10, so that calcium carbonate can be ground by the grinding rollers that have passed through multiple times during the grinding process, so that the finished product ground by the device is more delicate, and the grinding efficiency of the device is improved by the cooperation of the grinding disc 10 and multiple grinding rollers 1 18 and 19.

[0038] Reference Figure 2 and Figure 4 , a separation motor 12 is fixedly connected to the outer wall 7, a grid impeller 13 is fixedly connected to the output end of the separation motor 12, and the grid impeller 13 is located in the discharge pipe 11.

[0039] The finished product after grinding falls on the feeding plate 22 due to gravity, and is thrown onto the annular plate 23 as the feeding plate 22 rotates. At the same time, air is sucked from the outside of the device through the discharge pipe 11, driving the air flow to enter from the air inlet 25 and driving the finished product to be lifted upward along the feeding trough. The finished product is more easily entered into the discharge pipe 11 by the influence of the arc-shaped top plate 17. When the finished product is drawn out of the discharge pipe 11, the separation motor 12 drives the grid impeller 13 to rotate, thereby screening the finished product in the air flow, so that larger particles are knocked onto the grinding disc 10 for re-grinding. This enables the device to screen the finished products by itself, improves the quality control ability of the device in production, allows substandard raw materials to be re-grinded, and improves the quality of the finished products of the device.

[0040] Reference Figure 2 The feed pipe 26 is fixedly connected to the inner side wall 8 , and the end of the feed pipe 26 corresponds horizontally to the conical block 14 and the inclined plate 16 .

[0042] Working principle: When the device is used to grind calcium carbonate, firstly, the calcium carbonate raw material is put into the inner wall 8 through the feed pipe 26. When the raw material falls into the inner wall 8, the raw material is guided by the conical block 14 and the inclined plate 16 to move into the gap between the grinding disc 10 and the grinding wall 9, so that the feeding efficiency of the device is faster. At the same time, the driving motor 3 is started to drive the active roller 4 to rotate, thereby driving the belt 5 to rotate the driven roller 6, so that the grinding disc 10 rotates, and the raw material enters the grinding groove 21 during the falling process, and is ground by the grinding roller 18 and the grinding roller 2 19 that rotate with the rotation of the grinding disc 10, so that the calcium carbonate can be ground by the grinding rollers that have passed through multiple times during the grinding process;

[0043] The finished product after grinding falls on the feeding plate 22 due to gravity, and is thrown onto the annular plate 23 as the feeding plate 22 rotates. At the same time, air is sucked outside the device through the discharge pipe 11, driving the air flow to enter from the air inlet 25 and driving the finished product to be lifted upward along the feeding trough. The finished product is more easily entered into the discharge pipe 11 due to the influence of the arc-shaped top plate 17. When the finished product is drawn out from the discharge pipe 11, the separation motor 12 drives the grid impeller 13 to rotate, thereby screening the finished product in the air flow, so that larger particles are knocked onto the grinding disc 10 for re-grinding.
