DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The present invention will be described in detail below with reference to the accompanying drawings.

[0018] Embodiment 1:

[0019] The following is combined with Figure 1-3 The present embodiment describes an energy-saving and efficiency-enhancing graphite grinding equipment, comprising: a grinding cylinder 1, the grinding cylinder 1 is horizontally arranged and has a feed port 2 and a discharge port 3 at the upper and lower ends respectively, the grinding cylinder 1 is provided with multiple and parallel arrangements, the feed ports 2 and discharge ports 3 of adjacent grinding cylinders 1 are connected through a feeding cylinder 4, the grinding cylinder 1 and the feeding cylinder 4 are fixed on both sides by a frame 5, the discharge port 3 of the grinding cylinder 1 is connected with a filter plate 6, the filter holes of the filter plate 6 decrease from top to bottom, a medium shifting mechanism 7 and a medium are arranged in the grinding cylinder 1, the medium particle size decreases from top to bottom, the medium particle size in the same grinding cylinder 1 is larger than the filter hole diameter, a spiral blade 8 is arranged in the feeding cylinder 4, the spiral blade 8 is connected to a conveying shaft 9, and the conveying shaft 9 is rotatably connected in the frame 5, a slide groove 10 is provided on the inner wall at the feed port 2 of the grinding cylinder 1, a blocking plate 11 is slidably connected in the slide groove 10, and a driving mechanism 12 can drive the blocking plate 11 to slide and block the feed port 2;

[0020] Graphite ore is injected through the feed port 2 of the uppermost grinding cylinder 1, and the medium shifting mechanism 7 is turned on. The medium shifting mechanism 7 shifts the medium and the ore to collide with each other to complete the grinding. When the ore particle size is smaller than the filter hole diameter of the filter plate 6, the ore passes through the filter plate 6, the feed cylinder 4, and the feed port 2 of the lower grinding cylinder 1 and enters the lower grinding cylinder 1. Since the filter holes of the filter plate 6 decrease from top to bottom and the medium particle size gradually decreases, the finished particle sizes of the crushed ores in different grinding cylinders 1 are different. The graded grinding greatly improves the grinding effect. When it is necessary to discharge the finished product in a certain grinding process, the blocking plate 11 is controlled by the driving mechanism 12 to close and block the feed port 2 of the lower grinding cylinder. The upper finished ore falls into the feed cylinder 4 and is transported by the spiral blade 8 to complete sampling or discharging.

[0021] The medium toggle mechanism 7 includes a core shaft 71, which is located inside the grinding cylinder 1 and is rotatably connected to the frame 5. The two ends of the core shaft 71 located inside the grinding cylinder 1 are respectively connected to toggle brackets 72 evenly distributed around the circumference, and the outer edge of the toggle bracket 72 is connected to a ring 73, and a toggle rod 74 is connected between the two end rings.

[0022] The power drives the core shaft 71 to rotate, and the core shaft 71 drives the toggle brackets 72 and the ring 73 at both ends to rotate. The ring 73 strengthens the toggle bracket 72. The ring 73 drives the toggle rod 74 to rotate, and the toggle medium and the ore are lifted and dropped to collide with each other to complete the grinding.

[0023] The cross section of the lever 74 is an isosceles triangle, and the tip of the triangle points to the axis of the core shaft 71;

[0024] The isosceles triangle-shaped lever 74 can well drive the medium and the ore to rise and fall, but will not drive the medium and the ore to rotate along with the lever 74 .

[0025] The driving mechanism 12 includes a driving chute 121, which is provided on the grinding cylinder 1, and a lug 122 is slidably connected in the driving chute 121, and the lug 122 is hinged to the telescopic end of the hydraulic cylinder 123, and the fixed end of the hydraulic cylinder 123 is hinged to the cylinder bracket 124, and the cylinder bracket 124 is connected to the outer surface of the grinding cylinder 1;
