Description

Technical Field

[0001] This utility model relates to the field of phosphate production technology, and in particular to a grinding device for phosphate production. Background Technology

[0002] Phosphates are salts of phosphoric acid, formed by the combination of phosphate ions and metal cations. Their molecular structure is tetrahedral, with a phosphorus atom at the center surrounded by four oxygen atoms. Phosphates have wide applications in industry and agriculture. They are used as fertilizers because phosphorus is one of the key nutrients required for plant growth. In addition, phosphates are used in food processing, water treatment, and cleaning agents. During production, phosphates are ground into powder using grinding equipment to facilitate mixing with other materials. Existing grinding equipment often uses a one-time process, which cannot guarantee the precision of the ground particles, thus presenting limitations. Therefore, it is necessary to design a grinding device for phosphate production to solve this problem. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding device for phosphate production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A grinding device for phosphate production includes a main body. A support column is fixedly installed on the bottom inner wall of the main body, and a support frame and a central tube are connected and installed at the top of the support column. A rotating seat is rotatably connected to the outside of the support frame, and a grinding layer is provided on the outside of the rotating seat. A first drive motor is fixedly installed inside the support column, and an auger is connected and installed on the output shaft of the first drive motor. A second drive motor is fixedly installed inside the support frame, and a drive gear is connected and installed on the output shaft of the second drive motor. A screen and a flow guide are provided on the outside of the support column, and a sealing door is connected to the outside of the main body via a hinge.

[0006] Preferably, the bottom outer wall of both the support frame and the central tube is provided with a through groove to facilitate the flow of phosphate.

[0007] Preferably, the top of the rotating seat is designed with an inclination and is polished to facilitate grinding and prevent phosphate from accumulating on the top of the rotating seat.

[0008] Preferably, the auger is located inside the central tube, and a protective cover is fixedly installed on the top of the central tube to prevent phosphate from entering the central tube during feeding and affecting processing efficiency.

[0009] Preferably, the drive gear meshes with the rotating seat, and the rotating seat has a gear groove adapted to the drive gear, so that the second drive motor can control the rotation of the rotating seat through the drive gear.

[0010] Preferably, the screen is inclined to facilitate the feeding of larger phosphate particles into the central tube, and a vibrator is provided at the bottom of the screen to prevent screen blockage.

[0011] The beneficial effects of this utility model are:

[0012] This invention uses a second drive motor and drive gear to control the rotation of the rotating seat and grinding layer to grind phosphates. Phosphates that meet the required precision are sieved through a screen, while larger particles are fed into a central tube and conveyed to the top by an auger for further grinding until they pass through the screen. This method allows for multiple grinding of substandard phosphates using only the rotating seat, significantly improving grinding precision and processing efficiency, and making it highly practical.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example: Refer to Figure 1-2A grinding device for phosphate production includes a main body 1. A support column 2 is fixedly installed on the inner bottom wall of the main body 1, and a support frame 3 and a central tube 4 are connected and installed at the top of the support column 2. The outer bottom walls of both the support frame 3 and the central tube 4 have through grooves to facilitate phosphate flow. A rotating seat 5 is rotatably connected to the outer side of the support frame 3, and a grinding layer 6 is provided on the outer side of the rotating seat 5. The top of the rotating seat 5 is inclined and polished to facilitate grinding and prevent phosphate accumulation on the top of the rotating seat 5. A first drive motor 7 is fixedly installed inside the support column 2, and an auger 8 is connected to the output shaft of the first drive motor 7. The auger 8 is located inside the central tube 4, and a protective cover 9 is fixedly installed on the top of the central tube 4 to prevent phosphate buildup during feeding. Phosphate entering the central tube 4 affects processing efficiency. A second drive motor 10 is fixedly installed inside the support frame 3, and a drive gear 11 is connected to the output shaft of the second drive motor 10. The drive gear 11 meshes with the rotating seat 5, and a gear groove adapted to the drive gear 11 is opened in the rotating seat 5, so that the second drive motor 10 can control the rotation of the rotating seat 5 through the drive gear 11. A screen 12 and a guide frame 13 are provided on the outside of the support column 2. The drive gear 11 meshes with the rotating seat 5, and a gear groove adapted to the drive gear 11 is opened in the rotating seat 5, so that the second drive motor 10 can control the rotation of the rotating seat 5 through the drive gear 11. A sealing door 14 is connected to the outside of the main body 1 through a hinge.

[0018] Working principle: During use, unprocessed phosphate is poured into the main body 1 from above, making contact with the top of the rotating seat 5, and then sliding outward until it contacts the grinding layer 6 and the inner wall of the main body 1 for grinding. The ground phosphate falls onto the screen 12, and the phosphate with the required particle size is screened onto the guide frame 13 and piled up. The unscreened phosphate is fed into the central tube 4 by vibration and is conveyed upward by the auger 8. It is then ground multiple times by the rotating seat 5 until the particle size meets the required level. After processing, the sealing door 14 is opened to remove the ground phosphate from the guide frame 13.
