[0017] 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.
[0018] See also Figure 1-3 , the utility model provides a technical solution:
[0019] A silicon carbide block crushing device comprises a crushing machine box 1, a feeding frame 2 is provided at the top position of the crushing machine box 1, and a material guide support 3 is fixedly connected to the upper left and upper right positions inside the crushing machine box 1, a first grinding roller 4 is respectively provided below the gap between a group of material guide supports 3, second grinding rollers 5 are rotatably installed at both sides of the center of the crushing machine box 1, a hinged card seat 6 is fixedly connected to the bottom end position of the material guide support 3, and a movable card plate 7 is rotatably connected to the inner side of the hinged card seat 6, a cleaning brush 8 is clamped on one side of the movable card plate 7 close to the first grinding roller 4, and an auxiliary slide rail 9 is fixedly connected to the middle and lower position of the other side of the movable card plate 7, and an auxiliary slide column 11 is slidably connected to the inner middle position of the auxiliary slide rail 9, telescopic rods 10 are fixedly installed at the middle positions of both sides inside the crushing machine box 1, and a second inclined plate 20 is fixedly connected to the lower position of one side of the material guide support 3.
[0020] Specifically, the interior of the crusher box 1 is connected to the interior of the feed frame 2, and a crushing roller 19 is rotatably installed above the connection between the feed frame 2 and the crusher box 1, and a first inclined plate 18 is adjacent to one side of the crushing roller 19. A group of first inclined plates 18 are respectively fixedly installed at the lower positions on both sides of the interior of the feed frame 2. When the silicon carbide blocks to be processed naturally fall into the interior of the crusher box 1 through the interior of the feed frame 2, a group of first inclined plates 18 can guide and assist the silicon blocks in the falling process from both sides of the interior of the feed frame 2. At the same time, the crushing device will use the force generated by a group of crushing rollers 19 rotating in the same direction to crush and refine the unevenly broken silicon carbide blocks.
[0021] Specifically, a collection box 15 is slidably connected to the lower part of the crushing box 1, a filter bracket 13 is provided just above the collection box 15, and a filter screen 14 is provided at the middle part of the inclined surface of the filter bracket 13. The filter screen 14 has a "V"-shaped structure, and the filter screen 14 is arranged just below a group of second grinding rollers 5. As the silicon carbide block is fully ground and crushed twice and converted from a block form to a powder form, when the silicon carbide powder brought out from the group of second grinding rollers 5 falls above the filter bracket 13, the filter screen 14 arranged in an inclined shape will filter the ground and crushed silicon carbide powder. The silicon carbide micropowder is filtered and screened; side openings 16 are integrally formed at the middle and lower positions on both sides of the crusher box 1, and side boxes 17 are adjacent to the lower positions on both sides of the crusher box 1. The lower left end and the lower right end of the filter bracket 13 extend into the inside of the side opening 16 respectively. As the silicon carbide micropowder falls to the top of the filter bracket 13, the silicon carbide micropowder that is ground and crushed qualified will pass through the mesh holes on the filter screen 14 and fall into the inside of the aggregate drawer 15, and the silicon carbide micropowder that is unqualified will fall into a group of side boxes 17 along the inclined surface formed by the filter screen 14 and the filter bracket 13.
[0022] Specifically, the inner diameter of the first grinding roller 4 is larger than the inner diameter of the second grinding roller 5, and the roller shaft provided in the middle of the second grinding roller 5 and the roller shaft provided in the middle of the first grinding roller 4 are connected by a transmission belt 12, and the outer surfaces of the first grinding roller 4 and the second grinding roller 5 are respectively fitted with the brush surfaces of the cleaning brush 8, and the cleaning brush 8 is symmetrically arranged along the vertical center axis of the crushing machine box 1. The movable end of the telescopic rod 10 and the rear end of the auxiliary sliding column 11 are fixedly connected, and the telescopic rod 10 is transmission-connected through the auxiliary slide rail 9, the auxiliary sliding column 11 and the movable card plate 7. The first grinding roller 4 and the crushing machine box 1 are rotationally connected. After a group of cleaning brushes 8 are tilted, a group of cleaning brushes 8 will quickly clean up the silicon carbide micropowder adhered to the outer surface of the grinding roller.
[0023] Workflow: When the pulverizing device is used to refine the silicon carbide block, the silicon carbide block is first poured into the feeding frame 2, and is pre-crushed by the force generated by a group of crushing rollers 19 rotating in the same direction. Then, the pulverizing device performs a first grinding and crushing operation on the uniformly crushed silicon carbide block through a group of first grinding rollers 4 rotating in the same direction. At the same time, a group of second grinding rollers 5 driven by a group of first grinding rollers 4 grinds and crushes the silicon carbide block for a second time to ensure that the silicon carbide block can be fully ground and crushed into a micro powder. Finally, the unqualified silicon carbide micro powder is separated by the filter 14, and the qualified silicon carbide micro powder falls into the aggregate drawer 15 for collection. The entire pulverizing device can complete the entire grinding and crushing operation;
[0024] At the same time, after a group of first grinding rollers 4 and a group of second grinding rollers 5 are respectively installed in the crusher box 1, a group of telescopic rods 10 will push a group of movable card plates 7 in the same direction toward the middle of the box through the auxiliary sliding column 11 and the auxiliary sliding rail 9, so that the cleaning brush 8 adjusted to the inclined state can fit together with the outer surfaces of the first grinding roller 4 and the second grinding roller 5. When the crushing device uses a group of first grinding rollers 4 and a group of second grinding rollers 5 to grind and crush silicon carbide blocks, the group of cleaning brushes 8 in the inclined state can quickly clean up the silicon carbide powder adhering to the outer surfaces of the two groups of grinding rollers without affecting the normal rotation of the two groups of grinding rollers.
[0025] 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.
