[0019] 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.

[0020] Please see Figures 1-2 This utility model provides a sorting device for processing calcium fluoride tailings, including a tank 1. The inner wall of the tank 1 has a conical protrusion 2. The conical protrusion 2 is provided with coarse grinding teeth 7, which provide a basic structure for coarse grinding. The conical protrusion 2 can guide the tailings to concentrate in a specific area, while the coarse grinding teeth 7 increase the friction and impact area and enhance the coarse grinding effect.

[0021] Grinding component 3 and screening component 4 are respectively installed inside tank body 1 from top to bottom;

[0022] The driving component 5 is disposed between the grinding component 3 and the screening component 4;

[0023] The grinding component 3, in conjunction with the coarse grinding tooth 7, is used to coarsely grind the calcium fluoride tailings. The grinding component 3 is used to provide power to the drive component 5 so that the screening component 4 can vibrate.

[0024] Specifically, refer to Figure 2 The grinding component 3 includes a support 31 installed on the inner wall of the tank 1; a rotating frame 32 rotatably installed at the bottom of the support 31; a second coarse grinding tooth 33 sleeved on the outer wall of the rotating frame 32, which forms an interlaced friction and impact with the first coarse grinding tooth 7 when the rotating frame 32 rotates, thus efficiently crushing calcium fluoride tailings; and a servo motor 34 installed inside the support 31 and whose output end is connected to the top of the rotating frame 32.

[0025] Specifically, refer to Figure 2 The screening component 4 includes three support plates 41 disposed inside the tank body 1; a spring 42 disposed on the top of the support plate 41; and a screening plate 43 disposed on the top of the spring 42 and which can slide in the tank body 1. One end of the screening plate 43 can slide through the inner wall of the tank body 1 to facilitate the discharge of screened particles. The screen holes on the two upper screening plates 43 gradually decrease from top to bottom to achieve graded screening. The two adjacent screening plates 43 are connected by a connecting column 44 to ensure synchronous transmission of vibration and maintain the integrity of the structure.

[0026] Specifically, refer to Figure 2 The screening plates 43 are set at an inclination, and the inclination directions of the three screening plates 43 are staggered. The inclination setting can extend the falling stroke of tailings, and the staggered inclination direction can prevent particles from concentrating and flowing, thus improving the comprehensiveness of screening.

[0027] Specifically, refer to Figure 2 The driving component 5 includes a turntable 51 disposed at the bottom of the rotating frame 32; a bevel ring 52 disposed at the top of the uppermost screening plate 43; and several guide wheels 53 disposed at the top of the turntable 51 and in contact with the top of the bevel ring 52.

[0028] In this embodiment, when the rotating frame 32 rotates, the guide wheel 53 rubs against the bevel tooth ring 52. Combined with the upward elastic force of the spring 42 and the downward push of the bevel tooth, it can drive the screening plate 43 to vibrate, converting the grinding power into screening power, which is energy-saving and environmentally friendly.

[0029] Specifically, refer to Figure 2 The outer wall of the screening plate 43 is fitted with a piston sleeve 6 that can slide with the tank body 1, which plays a sealing role and prevents tailings powder from leaking.

[0030] Working principle

[0031] The servo motor 34 starts, driving the rotating frame 32 to rotate. The coarse grinding teeth 33 and the coarse grinding teeth 7 on the conical protrusion 2 cooperate to coarsely grind and crush the calcium fluoride tailings. The rotation of the rotating frame 32 drives the bottom turntable 51 to rotate. The guide wheel 53 on the turntable 51 rubs against the conical tooth ring 52, causing the uppermost screening plate 43 to vibrate. This vibration is transmitted to the lower screening plate 43 through the connecting column 44. The spring 42 assists in shock absorption and reset, enhancing the screening effect. The inclined and staggered screening plates 43 extend the tailings travel, allowing them to fully contact the screen holes and achieve efficient grading and screening. The piston sleeve 6 ensures smooth sliding of the screening plate 43, improving the stability and sealing of the equipment. The entire process effectively utilizes the grinding power for screening, reducing additional energy consumption. Compared with traditional equipment, the coarse grinding is more thorough, and the screening is more efficient and accurate.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
