[0002] Calcium carbonate is an inorganic compound commonly known as limestone, limestone, stone powder, etc. Calcium carbonate is alkaline, basically insoluble in water, soluble in hydrochloric acid. It is one of the common substances on earth, existing 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.

[0003] After searching, the existing Chinese patent announcement number is: CN215996988U, which provides a light calcium carbonate grinding mill, including a base frame and an outer shell. The inner side of the outer shell is provided with a feed channel, a grinding trough and a discharge channel which are connected from top to bottom, and the outer shell is assembled from two upper and lower shell seats. A grinding ball is provided on the inner side of the grinding trough. Through the setting of the grinding trough and the grinding ball on the inner side of the outer shell, the driving mechanism can be used to drive the grinding ball to rotate on the inner side of the grinding trough. Combined with the setting of the inner grinding head and the outer grinding head, the grinding effect of the calcium carbonate block during processing can be guaranteed.

[0004] Although the above patent can ensure the grinding effect of calcium carbonate blocks during processing, the above device still has the following problems: since there is no shaking mechanism in the device, the ground material in the device falls directly onto the screen plate, making it easy for the material to accumulate on the top of the screen plate, and causing the light calcium carbonate powder to not be disturbed, resulting in a slow screening speed of the light calcium carbonate powder and a prolonged screening process. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Please refer to Figure 1-4, the present utility model provides a technical solution: a device for preparing light calcium carbonate, including a device body 1. The device body 1 is of an existing structure and will not be elaborated here. A grinding structure is arranged inside the device body 1. Through the grinding structure, the device body 1 can grind light calcium carbonate. A discharge chute 3 is opened inside the device body 1, and a discharge chute 2 extending to the outside of the device body 1 is opened inside the device body 1. The inside of the discharge chute 2 is communicated with the inside of the discharge chute 3. Through the discharge chute 3, the ground light calcium carbonate particles can be discharged into the inside of the discharge chute 2 and discharged to the outside of the device body 1 through the discharge chute 2. A screening frame 5 is rotatably connected at the communicating place of the discharge chute 2 and the discharge chute 3. A screening plate 6 is arranged inside the screening frame 5. Through the screening plate 6, the ground light calcium carbonate powder can be screened. Larger particles are discharged through the inside of the discharge chute 2, and the screened finished products are discharged through the inside of the discharge chute 3. A support plate 14 is fixedly connected to the bottom of the screening frame 5. A second transmission groove 15 is opened inside the support plate 14. A U-shaped transmission frame 10 is arranged inside the discharge chute 3. The cross-section of the U-shaped transmission frame 10 is U-shaped. A second transmission rod 16 is fixedly connected to the side of the U-shaped transmission frame 10 close to the support plate 14. The surface of the second transmission rod 16 is movably connected with the inside of the second transmission groove 15. The second transmission rod 16 can rotate and move inside the second transmission groove 15. A placement groove 7 is opened on the side of the device body 1 away from the discharge chute 2. A motor 8 is fixedly connected inside the placement groove 7. The motor 8 is of an existing structure and will not be elaborated here. The output end of the motor 8 rotates through the inside of the placement groove 7 and extends to the inside of the discharge chute 3. A transmission plate 9 is fixedly connected to the output end of the motor 8. A first transmission rod 11 is fixedly connected to the side of the transmission plate 9 away from the output end of the motor 8. A first transmission groove 12 extending to the outside of the U-shaped transmission frame 10 is opened inside the U-shaped transmission frame 10. The surface of the first transmission rod 11 is movably connected with the inside of the first transmission groove 12. The first transmission rod 11 can rotate and move inside the first transmission groove 12.

[0019] Further, a baffle 4 is fixedly connected inside the discharge chute 3. The baffle 4 is arranged obliquely inside the discharge chute 3. Through the discharge chute 3, the ground light calcium carbonate powder can fall more smoothly on the top of the screening plate 6 for screening.

[0020] Further, two symmetrical sliding grooves 17 are opened inside the device body 1. The inside of the sliding grooves 17 is communicated with the inside of the discharge chute 3. A limiting frame 13 is slidably connected inside the sliding grooves 17. The side of the limiting frame 13 close to the U-shaped transmission frame 10 is fixedly connected to the surface of the U-shaped transmission frame 10. The cross-sections of the limiting frame 13 and the sliding grooves 17 are both L-shaped. Through the mutual cooperation of the limiting frame 13 and the sliding grooves 17, the moving direction of the U-shaped transmission frame 10 can be restricted, and to a certain extent, the U-shaped transmission frame 10 can move up and down more smoothly.

[0021] The staff starts the motor 8 through an external control device. Since the first transmission rod 11 is arranged on the side far from the motor 8, when the motor 8 drives the transmission plate 9 to rotate, the transmission plate 9 drives the U-shaped transmission frame 10 to move up and down inside the discharge chute 3 through the first transmission rod 11 and the first transmission groove 12. At the same time, the U-shaped transmission frame 10 drives one side of the screening frame 5 to rotate up and down through the second transmission rod 16 and the second transmission groove 15, and the screening frame 5 can screen the ground light calcium carbonate through the screening plate 6. At the same time, to a certain extent, it reduces the situation that the light calcium carbonate powder directly falls on the top of the screening plate 6, resulting in the light calcium carbonate powder not being disturbed and the screening speed of the light calcium carbonate powder being slower. Thus, it makes it more convenient for the staff to use the device to prepare and process light calcium carbonate.

[0022] Furthermore, a collection box 20 is arranged at the bottom of the equipment body 1, and the screened light calcium carbonate powder can be centrally collected through the collection box 20.

[0023] Furthermore, two symmetrical T-shaped grooves 18 are opened at the bottom of the equipment body 1. Two symmetrical T-shaped frames 19 are fixedly connected to the top of the collection box 20. The cross-sections of the T-shaped frames 19 and the T-shaped grooves 18 are both T-shaped. The surface of the T-shaped frame 19 is slidably connected to the inside of the T-shaped groove 18. Since the cross-sections of the T-shaped frames 19 and the T-shaped grooves 18 are both T-shaped, the position of the collection box 20 can be limited in terms of positioning, and the positioning and installation of the collection box 20 are more convenient.

[0024] Working principle: For such a device for preparing light calcium carbonate, first, the staff starts the equipment body 1, so that the equipment body 1 can grind and process light calcium carbonate. The staff starts the motor 8 through an external control device. Since the first transmission rod 11 is arranged on the side far from the motor 8, when the motor 8 drives the transmission plate 9 to rotate, the transmission plate 9 drives the U-shaped transmission frame 10 to move up and down inside the discharge chute 3 through the first transmission rod 11 and the first transmission groove 12. At the same time, the U-shaped transmission frame 10 drives one side of the screening frame 5 to rotate up and down through the second transmission rod 16 and the second transmission groove 15, and the screening frame 5 can screen the ground light calcium carbonate through the screening plate 6. The screened light calcium carbonate powder can be centrally collected through the collection box 20.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
