Description

Technical Field

[0001] The utility model belongs to the technical field of graphite feeding, in particular to a material distributor for graphite crushed materials. Background Art

[0002] After the graphite raw material is crushed, it is transferred to the calcining furnace through a feeding system for calcination. Calcination removes impurities, improves purity and crystallinity, and enhances its physical and chemical properties. After pre-crushing, the graphite is calcined in a vertical graphitization furnace. Before adding the raw material, the furnace must be heated to the set temperature. Once the furnace reaches the set temperature, the raw material can be added. Before adding the raw material, the furnace door must be opened and the raw material can be added. After adding the raw material, the furnace door must be closed and the temperature must stabilize before reopening to remove the processed material.

[0003] Typically, vertical graphitization furnace equipment is evenly arranged in an array in a calcining workshop. The crushed materials to be calcined in the crushing workshop are transported to the calcining workshop by conveyor belt equipment for stacking. Therefore, when loading graphite materials into the vertical graphitization furnace equipment, each equipment needs to be added one by one. The traditional conveyor belt transportation method is time-consuming and labor-intensive, and the process of adding materials is inefficient. However, it is still difficult to directly put the materials into the furnace if each vertical graphitization furnace equipment is equipped with a conveyor belt to transport the graphite materials, and the process of adding materials into the furnace is extremely inconvenient.

The rotating body 21 can synchronously drive the hopper 22, the flexible material transfer tube 3, the telescopic hydraulic arm 4, the baffle 5, the bottom support 6 and the feeding soft rubber tube 8 to rotate to change the position of the feeding soft rubber tube 8, and the feeding soft rubber tube 8 can be lifted or lowered by the telescopic hydraulic arm 4 and the straight pipe section 31. Combined with the movement of the receiving rail car 2 along the track, the lower end of the feeding soft rubber tube 8 can be placed at the upper feeding port of the vertical graphitization furnace equipment.

[0038] As an example, Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the flexible material transfer pipe 3 is internally provided with a clearance-fit flexible material transfer anchor 7. The flexible material transfer anchor 7 comprises an anchor drive motor 71, a straight rod anchor 72, and a flexible segment anchor 73. The straight rod anchor 72 is a spiral blade-shaped, rotating material transfer rod. The straight rod anchor 72 is placed within the straight pipe section 31 of the flexible material transfer pipe 3. The outer top end of the straight pipe section 31 is bolted to the anchor drive motor 71, which drives the straight rod anchor 72 to rotate via a belt drive. Multiple sections of the flexible segment anchor 73 are provided within the flexible segment 32 of the flexible material transfer pipe 3. Each section of the flexible segment anchor 73 has a concave ball head 731 at its upper end and a convex ball head 732 at its lower end. Two adjacent sections of the flexible segment anchor 73 are rotatably connected via the concave ball head 731 and the convex ball head 732. The straight anchor 72 and the flexible segment anchor 73 are connected in a flexible transmission-type rotational connection via the concave ball head 731 and the convex ball head 732. A metal spiral blade 733 is welded to the outside of each flexible segment anchor 73. The metal spiral blade 733 is in the shape of a spiral blade, and the pitch of the metal spiral blade 733 is the same as the pitch of the spiral blade of the straight anchor 72. A rubber spiral connector 734 is provided between the metal spiral blade 733 and the spiral blade of the straight anchor 72. The rubber spiral connector 734 is made of a rubber material with good elasticity and wear resistance. The rubber spiral connector 734 is fastened by screws to connect the metal spiral blade 733 to the spiral blade of the straight anchor 72, ensuring continuous material transmission. The metal spiral blades 733 of two adjacent flexible segment anchors 73 are also connected by the rubber spiral connector 734, so that the spiral blade for spiral material transmission forms a complete and continuous spiral shape. The flexible material transfer anchor 7 can transfer the crushed material in the hopper 22 along the flexible material transfer tube 3 into the vertical graphitization furnace at the lower end of the feeding flexible rubber tube 8. The end of the feeding flexible rubber tube 8 is sequentially provided with a control valve 81, a manipulation handle 82, and a controller 83. The control valve 81 can be a manually or electrically controlled gate valve. The manipulation handle 82 allows the operator to manually pull the lower end of the feeding flexible rubber tube 8 to change its position. The controller 83 can be electrically connected to the material receiving rail car 2, the rotating body 21, the telescopic hydraulic arm 4, the anchor driving motor 71, and the control valve 81 respectively.

[0040] The rotating ball 7321 can be placed in the spherical recess 7311 for clearance fit, and the ball recess stop 7312 can cover the spherical recess 7311 and be threadedly connected through the screw cover 7313, so that the rotating ball 7321 can rotate in the spherical recess 7311 and will not fall off; the seat recess ball channel 7314 in the spherical recess 7311 and the ball recess ball channel 7322 on the rotating ball 7321 can form a smooth rolling channel for the metal ball 7323. When the rotating ball 7321 changes its angle in the spherical recess 7311, the metal ball 7323 rolls with clearance fit in the seat recess ball channel 7314 and the ball recess ball channel 7322. The rotating ball 7321 can form a torque transmission between the metal ball 7323 and the spherical recess 7311, ensuring that the flexible segment anchor 73 with multiple ends connected in sequence can bend and rotate synchronously, so that the crushed material moves from the flexible segment 32 to the straight pipe section 31, and is transferred from the straight rod anchor 72 in the straight pipe section 31 to the feeding flexible rubber tube 8 and falls into the vertical graphitization furnace. The utility model can uniformly receive graphite flakes through a unified receiving station 1 and uniformly store them in a distribution box 11. The hopper 22 of the receiving rail car 2 can receive the graphite flakes in the distribution box 11 by triggering a material valve 13. During loading, the telescopic hydraulic arm 4 can change the inclination angle of the flexible material transfer tube 3, and the rotating body 21 can drive the hopper 22 and the flexible material transfer tube 3 to rotate and change their orientation, ensuring that the feeding flexible rubber hose 8 can be placed above the furnace for rapid feeding into the furnace. The device has a simple structure, good practicality, small footprint, low investment, and high economic benefits.
