Technical Field

[0001] The utility model relates to the field of graphite processing, in particular to graphite ore crushing equipment. Background Art

[0002] Graphite is an allotrope of the element carbon. Each carbon atom is connected to three other carbon atoms (arranged in a honeycomb-like hexagonal shape) by covalent bonds to form a covalent molecule. Since each carbon atom releases an electron, those electrons can move freely, so graphite is a conductor. Graphite is one of the softest minerals. Its uses include making pencil leads and lubricants.

The jaw type is prone to leaving long and flat large pieces of ore during crushing, while the rotary type is prone to damage large flake graphite due to high-speed rotation. The utility model solves the above problems. Utility Model Content

[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.

[0016] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is active on connecting parts such as hinges, pins and short shafts.

[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 a graphite ore crushing device, comprising: an input shaft 1, the input shaft 1 is horizontally rotatably connected to the side wall of the crushing chamber 2, the input shaft 1 is slidably connected to the sleeve 3, the sleeve 3 is connected to the pressure plate 4, the edge of the pressure plate 4 is rotatably connected to a slip ring 5, the slip ring 5 is slidably connected to a sliding column 6, the slip ring 5 is connected to the telescopic end of a hydraulic cylinder 7, the fixed end of the hydraulic cylinder 7 is connected to the inner wall of the crushing chamber 2, the sliding column 6 is provided with a plurality of circular arrays connected to a fixed plate 8, the distance between adjacent sliding columns 6 is not greater than the average size of the ore, the fixed plate 8 is connected to the inner wall of the crushing chamber 2 through a bracket 9, a through hole is provided at the center of the fixed plate 8, the through hole is connected to a feed pipe 10, the upper end of the feed pipe 10 is connected to the top wall of the crushing chamber 2, and the upper end of the feed pipe 10 is connected to a hopper 11;

[0020] The ore is injected through the hopper 11, and the ore moves to the through hole of the fixed plate 8. The power of the input shaft 1 is turned on, and the hydraulic cylinder 7 is controlled to reciprocate and extend. The hydraulic cylinder 7 drives the slip ring 5 to slide on the slide column 6, and the slip ring 5 drives the pressure plate 4 to move away from the fixed plate 8. The ore enters between the pressure plate 4 and the fixed plate 8. Since the distance between adjacent slide columns 6 is not greater than the average size of the ore, the ore will not fall from the gap between the slide columns 6. The pressure plate 4 drives the sleeve 3 to slide on the input shaft 1, so that the transmission will not be interrupted. When the slip ring 5 drives the pressure plate 4 to approach the fixed plate 8, the ore is squeezed and crushed, and the pressure plate 4 rotates while displacing. Some unbroken special-shaped ores are squeezed and crushed as the pressure plate rotates, and due to the low speed and short crushing time, large flake graphite will not be damaged.

[0021] The pressure plate 4 is a concave disc-shaped structure, and the pressure plate 4 is buckled on the fixed plate 8. The inner edge of the pressure plate 4 is provided with a chamfer extending to the bottom of the pressure plate 4;

[0022] The concave disc-shaped pressure plate 4 can better drive the movement of ore when it rotates, and the crushing effect is better. When the pressure plate 4 is away from the fixed plate 8, the ore remaining in the pressure plate 4 can also slide out along the chamfered surface of the inner edge of the pressure plate 4 without any residue.

[0023] The inner surface of the pressure plate 4 is connected with a crushing tooth 12, and the crushing tooth 12 is located in the overlapping area of ​​the pressure plate 4 and the fixed plate 8;

[0024] The crushing teeth 12 are added to make it easier for the ore to rotate with the pressure plate 4. The top of the crushing teeth 12 squeezes the ore to make it easier to crush the ore by breaking the surface.

[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
