Description

Technical Field

[0001] This utility model relates to the field of material grinding technology, and in particular to a toothed disc crusher. Background Technology

[0002] Material is fed into the crushing chamber from the hopper. It is thrown from the center to the chamber wall by the centrifugal force generated by the rotation of the moving toothed disc. It is crushed by impact, shearing, grinding and collision between the moving and fixed toothed discs. Finally, the fine material is discharged from the bottom through the annular screen plate, and the coarse powder is repeatedly crushed in the machine.

[0003] Depending on the degree of grinding required for different materials, different movable toothed discs are used. The finer the material is ground, the smaller the gap between the grinding teeth of the movable toothed disc, the grinding teeth of the fixed toothed disc, and the filter plate. However, replacing the movable toothed disc is more troublesome, and preparing movable toothed discs of different specifications is more costly. Utility Model Content

[0004] The purpose of this invention is to provide a toothed disc crusher, which has the advantage of being easy to adjust the gap between the grinding blocks and the screen, and can grind different materials.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A toothed disc crusher includes a cavity with a cylindrical screen embedded inside, the screen being fixedly connected to the cavity. A grinding disc is disposed inside the cavity, located inside the cylindrical screen. A cover is hinged to the opening of the cavity, and a hopper is fixedly connected to the cover. A mounting cover is fixedly connected to one bottom surface of the grinding disc, and the mounting cover is rotatably connected to the inner wall of the cavity. Multiple sliders are slidably connected to the grinding disc, and the sliders slide radially around the center of the grinding disc. One end of each slider is located inside the mounting cover, and protruding posts are fixedly connected to both sides of the slider end inside the mounting cover. A grinding block is fixedly connected to the other end of the slider. A connecting plate is placed inside the mounting cover. A moving mechanism is provided between the connecting plate and the grinding disc. Multiple pairs of slotted plates corresponding to the slider are fixedly connected to the connecting plate. Each slotted plate has an inclined waist-shaped groove. One end of the protruding post of each slider is fixedly connected between two slotted plates of the same pair. The protruding posts on both sides of the slider are respectively embedded in the waist-shaped grooves of the two slotted plates. The cover has multiple rings of slots. Each ring of slots surrounds the center of the cover. Each slot on the same ring is embedded with a grinding post and is detachably connected to the cover.

[0007] Using the above technical solution, the material is poured into the hopper on the cover. The material slides down from the hopper, passes through the cover, and enters the cavity. The grinding disc rotates, causing the grinding blocks above it to rotate relative to the grinding column. When the grinding blocks pass the grinding column, the material between the grinding blocks and the grinding column is sheared by both. With continuous operation, the material is gradually sheared and reduced in size, making the material volume smaller than the distance between the grinding blocks and the grinding column when they are aligned. Then, the material falls onto the screen, where the grinding blocks crush and impact the material, further pulverizing it. The fine powder that meets the requirements falls out of the screen, while the coarse powder continues to be ground in the cavity. When different types of materials are pulverized to different degrees, the screen is replaced first. Then, the connecting plate is moved by the moving mechanism, which in turn moves the trough plate. One side wall of the waist-shaped groove of the trough plate exerts a force on the protrusion of the connecting block, causing the connecting plate to move. The grinding blocks move relative to the grinding disc, and the connecting block drives the grinding blocks to move, thus moving the grinding blocks away from or closer to each other, and the grinding blocks move closer to or further away from the side wall of the screen. The distance between the grinding blocks and the side wall of the screen increases or decreases. Then, the grinding column on the cover is removed from its slot. After that, the removed grinding column is moved away from or closer to the center of the cover and then installed in the corresponding slot. If it is not necessary to grind too finely, the corresponding screen is replaced in the cavity. The moving mechanism makes the grinding blocks move closer to each other and away from the inner wall of the screen. When the material is ground to a size smaller than the gap between the grinding block and the screen, the material powder will fall out of the screen. Then, the grinding column is moved from the mounting hole on the original ring to the mounting hole on the inner ring. It is not necessary to remove the grinding disc, which reduces the workload and also reduces the cost by eliminating the need to prepare multiple sizes of grinding discs.

[0008] Preferably, the moving mechanism consists of a screw and a nut. The nut is located on the opposite side of the grinding disc where the mounting cover is located, and is rotatably connected to the center of the grinding disc. One end of the screw passes through the nut and the grinding disc and is located inside the mounting cover. The screw is threadedly connected to the nut and slidably connected to the grinding disc. The end of the screw inside the mounting cover is fixedly connected to the connecting plate.

[0009] Using the above technical solution, tightening the nut causes the screw to move in a direction perpendicular to the surface of the grinding disc. The screw then moves the connecting plate, which in turn causes the grinding block to move in a direction parallel to the grinding disc via the waist-shaped groove and the protrusion.

[0010] Preferably, one end of the grinding column is integrally formed with a threaded column, the threaded column of the grinding column passes through the slot, the end face of the grinding column with the threaded column is fixedly connected to the inner side of the cover door, one end of the threaded column is located on the outer side of the cover door, and the threaded column is threadedly connected to a nut, the end face of the nut is abutting against the inner side of the cover door, thereby fixing the grinding column on the cover door.

[0011] Using the above technical solution, the grinding post can be removed from the grinding disc by unscrewing the nut from the threaded post of the grinding post.

[0012] Preferably, a dust collection mechanism is placed on the side of the toothed disc crusher. The dust collection mechanism includes a collection box, a fan is connected to the collection box through a connecting pipe, and a dust collection pipe is connected to the collection box. The opening of the dust collection pipe is close to the discharge port of the toothed disc crusher cavity.

[0013] Using the above technical solution, after the material is crushed, it falls out of the screen and then into the material bucket from the discharge port of the cavity. At the same time, the dust collection mechanism sucks dust from the air into the collection box to prevent dust from entering the material bucket along with the crushed material and affecting the use of the material.

[0014] Preferably, a locking mechanism is provided between the cover and the cavity. The locking mechanism includes a connecting shaft, a second screw, a threaded cylinder, and a baffle. The connecting shaft is rotatably connected to the outside of the cavity near its opening edge. The second screw is fixedly connected to the connecting shaft. The threaded cylinder is threadedly connected to the screw. A handle is fixedly connected to the end of the threaded cylinder away from the screw. The baffle is fixedly connected to the cover and has a slot that matches the second screw.

[0015] Using the above technical solution, first rotate the cover door to cover the opening of the cavity, then rotate the second screw so that one end of it is embedded in the groove of the baffle. By turning the handle, the threaded cylinder moves on the screw, and the end face of the threaded cylinder abuts against the surface of the baffle, thereby locking the cover door and the cavity together and sealing the cavity.

A discharge port is provided on the lower side of the cavity 1. A connecting shaft 20 is rotatably connected to the outer edge of the cavity 1 near its opening. A screw 21 is fixedly connected to the connecting shaft 20. A threaded cylinder 22 is threadedly connected to the screw, and a handle is fixedly connected to the end of the threaded cylinder 22 away from the screw.

[0025] See Figure 2 , Figure 5 and Figure 6 The cavity 1 contains a grinding disc 3 located inside the cylindrical screen 2. A cover 4 is hinged to the opening of the cavity 1, and a hopper is fixedly connected to the cover 4. A mounting cover 5 is fixedly connected to one bottom surface of the grinding disc 3, and the mounting cover 5 is rotatably connected to the inner wall of the cavity 1. Multiple sliders 6 are slidably connected to the grinding disc 3, and the sliders 6 slide around the center of the grinding disc 3 in the radial direction. One end of the slider 6 is located inside the mounting cover 5, and protrusions 7 are fixedly connected to both sides of the end of the slider 6 inside the mounting cover 5. A grinding block 8 is fixedly connected to the other end of the slider 6. A nut 15 is rotatably connected to the center of the grinding disc, and a screw is threaded onto the nut 15. The screw passes through the grinding disc 3 and is slidably connected to the grinding disc 3. One end of the screw 14 is located in the mounting cover 5, and a connecting plate 9 is fixedly connected to the end of the screw located in the mounting cover 5. Multiple pairs of slotted plates 10 corresponding to slider 6 are fixedly connected to the connecting plate 9. Each slotted plate 10 has an inclined waist-shaped groove 11. One end of each slider 6 is fixedly connected to a protruding post 7 located between two slotted plates 10 of the same pair. The protruding posts 7 on both sides of the slider 6 are respectively embedded in the waist-shaped grooves 11 of the two slotted plates 10.

[0026] See Figures 1 to 4The cover 4 has multiple concentric slots 12, each encircling the center of the cover 4. Each slot 12 on the same concentric circle is fitted with a grinding post 13. One end of the grinding post 13 has an integrally formed threaded post 16. The threaded post 16 passes through the slot 12, and the end face of the grinding post 13, fixedly connected to the threaded post 16, abuts against the inner side of the cover 4. One end of the threaded post 16 is located on the outer side of the cover 4. The threaded post 16 is threadedly connected to a nut 17, the end face of which abuts against the inner side of the cover 4, thus fixing the grinding post 13 to the cover 4. When the cover 4 is closed, the grinding post 13 is located inside the grinding block 8. A baffle 23 is fixedly connected to the cover 4, and the baffle 23 has a slot that matches the screw 21. A dust collection mechanism is placed on the side of the toothed disc crusher. The dust collection mechanism includes a collection box 18, a fan is connected to the collection box 18 through a connecting pipe, and a dust collection pipe 19 is connected to the collection box 18. The opening of the dust collection pipe 19 is close to the discharge port of the toothed disc crusher cavity 1.

[0027] Working principle: Rotate the cover 4 to cover the opening of the cavity 1, then rotate the screw 21 so that one end is embedded in the groove of the baffle 23. Turn the handle to rotate the threaded cylinder 22, which moves on the screw. The end face of the threaded cylinder 22 abuts against the surface of the baffle 23, thus locking the cover 4 and the cavity 1 together, sealing the cavity 1. Pour the material into the hopper on the cover 4. The material slides down the hopper, passes through the cover 4, and enters the cavity 1. The grinding disc 3 rotates, causing the grinding blocks 8 on top of it to rotate relative to the grinding column 13. When the grinding blocks 8 pass the grinding column 13, the material between the grinding blocks 8 and the grinding column 13 is sheared by both. With continuous operation, the material is gradually sheared and reduced in size, making the material volume smaller than the distance between the grinding blocks 8 and the grinding column 13 when they are aligned. Afterwards, the material falls onto the screen 2, and the grinding block 8 crushes and impacts the material, further pulverizing it. The fine powder that meets the requirements falls out of the screen 2, while the coarse powder continues to be ground in the cavity 1.

[0028] When grinding different types of materials to different degrees, first replace the screen 2, then tighten the nut 15 to move the screw 14 in a direction perpendicular to the surface of the grinding disc 3. The screw 14 moves the connecting plate 9, which in turn moves the groove plate 10. One side wall of the waist-shaped groove 11 of the groove plate 10 exerts a force on the protrusion 7 of the connecting block, causing the connecting block to move relative to the grinding disc 3. The connecting block then moves the grinding blocks 8, causing the grinding blocks 8 to move away from or closer to each other, and to move closer to or further away from the side wall of the screen 2. The distance between the grinding blocks 8 and the side wall of the screen 2 increases or decreases. Then, unscrew the nut 17 on the grinding column 13 to remove it from the groove 12 of the grinding disc 3. Move the removed grinding column 13 away from or closer to the center of the cover 4, and then install it in the corresponding groove 12. When fine grinding is not required, a corresponding screen 2 is installed inside chamber 1. The grinding blocks 8 are moved closer together and further away from the inner wall of screen 2 via a moving mechanism. When the material is ground to a size smaller than the gap between the grinding blocks 8 and screen 2, the powder will fall out of screen 2. Then, the grinding column 13 is moved from its original mounting hole on the innermost ring to a mounting hole on a more inner ring. This eliminates the need to remove the grinding disc 3, reducing workload and lowering costs by eliminating the need to prepare multiple sizes of grinding discs 3.
