Description

Technical Field

[0001] This utility model relates to the field of refractory material production technology, and in particular to a raw material crushing device for refractory material production. Background Technology

[0002] Chinese patent application CN202322278118.8 discloses a refractory material raw material crushing device, including crushing blades, connecting seats, and transmission rods. The transmission rod is connected to the transmission end of a drive motor, and the crushing blades are installed on the upper surface of the connecting seats. This device uses a drive motor to drive the transmission rod to rotate, which in turn drives multiple crushing blades to rotate through multiple connecting seats. The continuously rotating crushing blades crush the refractory material raw material that falls down. During this process, refractory material raw materials with a diameter larger than the diameter of the mesh of the barrier plate are blocked, allowing the multiple crushing blades to crush them again. At the same time, the transmission rod drives the drive pulley to rotate, which in turn drives the driven pulley to rotate through the transmission belt. This causes the grinding roller to drive multiple grinding protrusions to rotate together, so that the rotating grinding protrusions can squeeze and crush the refractory material raw material that falls into the grinding chamber.

[0003] The large gaps between the aforementioned shredder blades result in large refractory material particles after shredding, making the barrier mesh plate prone to clogging. Furthermore, it cannot continuously shred the refractory material, leading to low shredding efficiency of the device. Utility Model Content

[0004] To address the shortcomings of the comparative literature, this utility model provides a raw material crushing device for refractory material production, which solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a raw material crushing device for refractory material production, including a crushing box, a feeding hopper set at the top of the crushing box, and a support leg set at the bottom of the crushing box. A grinding plate with a filter hole inside is snapped into the bottom of the crushing box. A front cover and a rear cover are fixedly installed on both sides of the crushing box. A first crushing roller is rotatably connected inside the front cover and the rear cover. A first fixing plate and a second fixing plate are fixedly fitted on the outer sides of both ends of the first crushing roller, respectively, between the crushing box and the grinding plate. A second crushing roller is rotatably connected inside the first fixing plate and the second fixing plate, and is circumferentially distributed around the axial direction of the first crushing roller. A first gear located inside the first fixing plate is fixedly fitted on the outer side of one end of the second crushing roller. A second gear located outside the first crushing roller and meshing with the outer edge of the first gear is fixedly installed inside the front cover by bolts. A motor fixedly installed on the outer side of the rear cover is fixedly sleeved at one end of the first crushing roller extending outside the rear cover by a bushing.

[0006] Preferably, the grinding plate is provided with a discharge hopper located outside the filter holes.

[0007] Preferably, the end face of the front cover is provided with an annular boss that is movably sleeved inside the first fixed disk and located outside the first gear.

[0008] Preferably, the grinding plate has symmetrically distributed fixing blocks on its outer side, and a support rod that is movably fitted inside the grinding box is provided inside the fixing block, and the two ends of the support rod extending outside the grinding box are both engaged with retaining rings.

[0009] This utility model has the following advantages:

[0010] 1. Driven by a motor, the first and second crushing rollers rotate around the axial direction of the first crushing roller. Simultaneously, through the meshing transmission between the first and second gears, the second crushing roller rotates around its own axial direction. Thus, the first and second crushing rollers work together to crush the refractory material raw material. Furthermore, through cooperation with the grinding plate, the crushed refractory material raw material can be crushed again. The crushed refractory material raw material can be discharged to the outside through the filter holes. This structure enables the device to continuously crush the refractory material raw material, thereby improving the crushing efficiency of the device.

[0011] 2. The combination of the fixing block and the support rod can limit and support the grinding plate, and the limitation on the grinding plate can be released by removing the support rod, so as to facilitate the disassembly and replacement of the worn grinding plate.

Detailed Implementation

[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 to 6 A raw material crushing device for refractory material production includes a crushing box 1, a feeding hopper 2 located at the top of the crushing box 1, and support legs 3 located at the bottom of the crushing box 1. A grinding plate 5 with internally penetrating filter holes 4 is snapped into the bottom of the crushing box 1. A front cover 6 and a rear cover 7 are fixedly installed on both sides of the crushing box 1, respectively. A first crushing roller 8 is rotatably connected inside the front cover 6 and the rear cover 7. A first fixing plate 9 and a second fixing plate 10 are fixedly fitted on the outer sides of both ends of the first crushing roller 8, respectively, between the crushing box 1 and the grinding plate 5. Second crushing rollers 11, circumferentially distributed around the axial direction of the first crushing roller 8, are rotatably connected inside the first fixing plate 9 and the second fixing plate 10. Through the cooperation of the first fixing plate 9 and the second fixing plate 10, the first crushing roller 8 and the second crushing roller 11 can be crushed together. 1. Limiting support is provided to ensure that the first crushing roller 8 and the second crushing roller 11 can rotate synchronously under the drive of the motor 15. The outer side of one end of the second crushing roller 11 is fixedly fitted with the first gear 12 located inside the first fixed plate 9. The inside of the front end cover 6 is fixedly installed with the second gear 14 located outside the first crushing roller 8 and meshing with the outer edge of the first gear 12 by bolts 13. The second gear 14 can be limited and fixed by bolts 13, so that when the first fixed plate 9 rotates with the first crushing roller 8, the second crushing roller 11 can be driven to rotate synchronously around its own axis through the meshing transmission of the first gear 12 and the second gear 14. The end of the first crushing roller 8 extending outside the rear end cover 7 is fixedly sleeved with the motor 15 fixedly installed on the outside of the rear end cover 7.

[0021] The grinding plate 5 is provided with a discharge hopper 16 located outside the filter hole 4. The refractory material raw material particles after being crushed by the first crushing roller 8 and the second crushing roller 11 can be filtered through the filter hole 4. Larger particles can be crushed again by the cooperation of the second crushing roller 11 and the grinding plate 5, so as to ensure that the particle size of the crushed refractory material raw material is relatively uniform. The discharge hopper 16 can guide the refractory material raw material particles discharged from the filter hole 4 and facilitate their collection.

[0022] The end face of the front cover 6 is provided with an annular boss 17 that is movably sleeved inside the first fixed disk 9 and located outside the first gear 12. The cooperation between the first fixed disk 9 and the annular boss 17 can shield and protect the first gear 12 and the second gear 14, preventing the dust of the crushed refractory material raw material from entering the interior of the first fixed disk 9, which would cause the first gear 12 and the second gear 14 to not be fully meshed.

[0023] The grinding plate 5 is provided with symmetrically distributed fixing blocks 18 on its outer side. The fixing blocks 18 are movably fitted with a support rod 19 that is movably fitted inside the crushing box 1. The fixing blocks 18 and the support rod 19 can limit and support the grinding plate 5, so that the grinding plate 5 is not easily bent and deformed by external force during the crushing of refractory material raw materials by the second crushing roller 11 and the grinding plate 5. The two ends of the support rod 19 extending outside the crushing box 1 are clamped with retaining rings. The retaining rings can limit the axial movement of the support rod 19 and facilitate the disassembly and assembly of the support rod 19 by removing the retaining rings.

[0024] Working principle: Start the motor 15, which drives the first crushing roller 8, the first fixed plate 9 and the second crushing roller 11 to rotate synchronously around the axial direction of the first crushing roller 8. The rotation of the first fixed plate 9, in conjunction with the first gear 12 and the second gear 14, drives the second crushing roller 11 to rotate around its own axial direction. The refractory material raw material is added into the crushing box 1 through the feeding hopper 2. After the refractory material raw material falls between the first crushing roller 8 and the second crushing roller 11, it can be crushed and squeezed. The crushed refractory material raw material particles fall to the inner side of the grinding plate 5 and are filtered through the filter hole 4. Smaller particles are discharged to the inner side of the discharge hopper 16 through the filter hole 4, while larger particles are crushed and squeezed again by the second crushing roller 11 and the grinding plate 5 and then discharged to the outside through the filter hole 4.
