[0005]有鉴于此，本发明的目的在于提出一种活性炭纤维原料预处理装置，以解决上述筛分出的不合格料通常需要人工收集并重新投入破碎机进行二次破碎的问题
[0014] The beneficial effects of this invention are as follows: By setting two crushing rollers inside the processing box and an inverted V-shaped filter plate below the crushing rollers, the raw material falls directly into the filter plate for screening after being crushed by the crushing rollers, realizing the integrated operation of crushing and screening. There is no need to transfer the crushed material to a separate screening device, simplifying the pretreatment process and improving production efficiency. By setting the filter plate as an inverted V-shaped structure and fixing guide plates on both sides of the filter plate, the raw material that meets the particle size requirements can quickly fall through the filter plate to the discharge pipe for discharge, while the larger particle size raw material that is not filtered out will automatically slide down the upper surface of the filter plate to the conveying structure on both sides under the action of gravity.

By setting a conveying structure and a guide hopper inside the processing box, the conveying structure transports the raw material that is not filtered out from the filter plate to the guide hopper. The raw material slides back down between the two crushing rollers through the guide hopper, ensuring the uniformity of the output particle size and improving the utilization rate of raw materials. There is no need to manually collect the unfiltered raw material and put it back into the crusher for secondary crushing.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.
[0019] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 7 The present invention includes a processing box 1 and a base 2 fixedly installed at the bottom of the processing box 1. A feed hopper 3 is fixedly connected to the top of the processing box 1, and a discharge pipe 4 is fixedly connected to the bottom of the processing box 1. Two crushing rollers 5 are provided inside the processing box 1, and a drive structure for driving the two crushing rollers 5 to rotate in opposite directions is installed on the processing box 1. The processing box 1 contains a filter plate 6 located below the crushing roller 5. The filter plate 6 has an inverted V-shaped structure, and guide plates 7 are fixedly connected to both sides of the filter plate 6. A shaking unit for driving the filter plate 6 to shake is installed inside the processing box 1. Two guide hoppers 8 are fixedly connected inside the processing box 1, and the two guide hoppers 8 are respectively located above the two crushing rollers 5. Conveying structures are provided on both sides of the filter plate 6 to transport the raw materials that are not filtered out by the filter plate 6 into the guide hoppers 8. The raw materials to be crushed are added into the processing box 1 through the feed hopper 3, and the raw materials enter the two guide hoppers 5. Between the two crushing rollers 5, the two crushing rollers 5 are driven to rotate in opposite directions by the drive structure. The crushing rollers 5 crush the raw material. The crushed raw material is filtered through the filter plate 6. The raw material that meets the requirements falls into the discharge pipe 4 through the filter plate 6 and is discharged through the discharge pipe 4. The raw material that does not meet the requirements is slid from the upper surface of the filter plate 6 to the conveying structure. After the raw material is crushed once, the raw material that does not meet the requirements is conveyed to the guide hopper 8 through the conveying structure. The raw material slides between the two crushing rollers 5 through the guide hopper 8 for secondary crushing.
[0020] Example 2, based on Example 1, is... Figure 1 , Figure 3 and Figure 6 The conveying structure includes arc-shaped plates 9 respectively disposed on both sides of the filter plate 6. Side plates 10 are fixedly connected to both sides of each arc-shaped plate 9. Two hydraulic push rods 12 are fixedly connected to the bottom of the processing box 1. The telescopic ends of the two hydraulic push rods 12 are fixedly connected to the bottom of the two arc-shaped plates 9 respectively. A guide rod 13 is fixedly connected to the bottom of the arc-shaped plates 9, and the bottom end of the guide rod 13 penetrates through the processing box 1. A rotating plate 11 is disposed between the two side plates 10, and the bottom end of the rotating plate 11 contacts the inner wall of the arc-shaped plate 9. Connecting shafts 14 are fixedly connected to both sides of the rotating plate 11, and the connecting shafts 14 are rotatably connected to the side plates 10. A rotator for driving the connecting shafts 14 to rotate is mounted on the side plate 10. The rotator includes mounting brackets fixedly installed on the opposite side of the two side plates 10. The end of the connecting shaft 14 is fixedly connected to the housing 21, and a gear 15 is located inside the housing 21. The housing 21 is provided with a toothed plate 16 that meshes with the gear 15. A support bar 17 is fixedly connected to the top of the toothed plate 16 and passes through the housing 21. The housing 21 is provided with an elastic element that is adapted to the toothed plate 16. The elastic element includes a first support part 18 fixedly installed on the toothed plate 16. A prism 19 passes through the first support part 18. Both ends of the prism 19 are fixedly connected to the inner wall of the housing 21. A first compression spring 20 is sleeved on the outside of the prism 19. Both ends of the first compression spring 20 are fixedly connected to the bottom of the first support part 18 and the bottom of the inner wall of the housing 21, respectively. The top of the first support part 18 is in contact with the top of the inner wall of the housing 21. Unfiltered material on filter plate 6 slides from its upper surface into arc plate 9. After a single crushing operation, arc plate 9 is driven upward by hydraulic push rod 12, and arc plate 9 drives guide rod 13 to move upward relative to processing box 1. The guide rod 13 is designed to ensure that arc plate 9 moves smoothly vertically. When arc plate 9 moves to one side of guide hopper 8, the top of support bar 17 contacts the top of inner wall of processing box 1. As arc plate 9, mounting shell 21, and gear 15 continue to move upward, support bar 17 moves downward relative to mounting shell 21. Support bar 17 drives gear 15 to rotate via toothed plate 16. When the gear 15 rotates, it drives the rotating plate 11 to rotate via the connecting shaft 14. The rotating plate 11 scrapes the raw material in the arc plate 9 into the guide hopper 8, and the toothed plate 16 drives the first support part 18 to move downward relative to the prism 19. The first compression spring 20 is in a compressed state. Then the hydraulic push rod 12 drives the arc plate 9 to move downward to the initial height, and the support bar 17 no longer contacts the top of the inner wall of the processing box 1. The first compression spring 20 drives the first support part 18 and the toothed plate 16 to move upward relative to the mounting shell 21 to the initial position. When the two crushing rollers 5 rotate again, the two crushing rollers 5 can crush the raw material again.
[0021] Example 3, based on Example 1, is... Figure 3 , Figure 4 and Figure 7 The drive structure includes two first rotating shafts 29 rotatably mounted inside the processing chamber 1, and two crushing rollers 5 are respectively fixedly sleeved on the outside of the two first rotating shafts 29. A control housing 31 is fixedly connected to the outer wall of the processing chamber 1, and a second rotating shaft 32 is rotatably connected inside the control housing 31. Two first bevel gears 33 are fixedly sleeved on the outside of the second rotating shaft 32, and the tooth surfaces of the two first bevel gears 33 are arranged opposite each other. A second bevel gear 34 located inside the control housing 31 is fixedly connected to the end of the first rotating shaft 29, and the two second bevel gears 34 mesh with the two first bevel gears 33 respectively. A servo motor 35 is fixedly connected to the outer wall of the processing chamber 1, and the output end of the servo motor 35 is fixedly connected to the end of the second rotating shaft 32. The vibration unit includes four second support parts 2 fixedly mounted on the inner wall of the processing chamber 1. 2. A movable column 23 passes through the second support part 22. The bottom end of the movable column 23 and the corresponding guide plate 7 are fixedly connected by a connecting plate 24. A fixed ring 26 located above the second support part 22 is fixedly sleeved on the outside of the movable column 23. A stop plate 28 is slidably sleeved on the outside of the movable column 23. The bottom of the stop plate 28 contacts the top of the fixed ring 26. The stop plate 28 is fixedly connected to the inner wall of the processing box 1. A second compression spring 27 is sleeved on the outside of the movable column 23. The two ends of the second compression spring 27 contact the bottom of the fixed ring 26 and the top of the second support part 22, respectively. A support plate 25 is fixedly connected to the top of the movable column 23. Several protrusions 30 that cooperate with the support plate 25 are fixedly connected to both ends of the first rotating shaft 29. The support plate 25 is located below the first rotating shaft 29. The second rotating shaft 32 is driven to rotate by the servo motor 35. The second rotating shaft 32 drives the two first bevel gears 33 to rotate, and the tooth surfaces of the two first bevel gears 33 are arranged opposite to each other. The two first bevel gears 33 can drive the two second bevel gears 34 to rotate in opposite directions. The second bevel gears 34 drive the crushing rollers 5 through the first rotating shaft 29. The two crushing rollers 5 rotating in opposite directions can crush the raw materials. When the first rotating shaft 29 rotates, the first rotating shaft 29 drives the protrusions 30 to rotate synchronously. The bottom end of the protrusions 30 contacts the top of the support plate 25. As the protrusions 30 rotate... As the plate continues to rotate, the protrusion 30 pushes the support plate 25, the movable column 23, the connecting plate 24, and the guide plate 7 downward. The second compression spring 27 is in a compressed state. When the protrusion 30 is no longer in contact with the support plate 25, the second compression spring 27 pushes the movable column 23 and the fixed ring 26 upward. The top of the fixed ring 26 hits the bottom of the stop plate 28, causing the filter plate 6 to vibrate vertically. On the one hand, this causes the raw material on the upper surface of the filter plate 6 to slide down the conveying structure. On the other hand, the vertical vibration shakes out the raw material that is blocked in the filter holes of the filter plate 6.
[0022] Example 4, based on Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the top of the base 2 is in contact with a collection box 36 located below the discharge pipe 4. A positioning component that cooperates with the collection box 36 is installed on the top of the base 2. A movable sleeve 37 is slidably sleeved on the outside of the discharge pipe 4. The bottom end of the movable sleeve 37 is located inside the collection box 36. Iron plates 38 are fixedly connected to both sides of the movable sleeve 37. A magnet block 43 is provided on the top of the iron plate 38, and the magnet block 43 is fixedly connected to the bottom end of the processing box 1. Several guide posts 39 pass through the iron plate 38. The top end of the guide post 39 is fixedly connected to the bottom end of the processing box 1. A support plate 40 is fixedly connected to the bottom end of the guide post 39. The top of the support plate 40 is in contact with the bottom of the iron plate 38. The positioning component includes several limiting blocks 41 fixedly installed on the top of the base 2. A limiting sleeve 42 is sleeved on the outside of the limiting block 41, and the limiting sleeve 42 is fixedly connected to the collection box 36. The operator drives the movable sleeve 37 and the iron plate 38 to slide relative to the discharge pipe 4 and the guide column 39, so that the top of the support plate 40 no longer supports the bottom of the iron plate 38. The top of the iron plate 38 and the bottom of the magnet block 43 are magnetically attracted and fixed. The movable sleeve 37 is fixed relative to the discharge pipe 4. Then the operator places the collection box 36 above the base 2, and the limiting sleeve 42 is fitted outside the limiting block 41. Then the operator drives the movable sleeve 37 and the iron plate 38 to move down. The iron plate 38 is no longer magnetically attracted to the magnet block 43, so that the bottom end of the movable sleeve 37 is inserted into the collection box 36. The bottom of the iron plate 38 and the top of the support plate 40 come into contact. The crushed raw material can slide into the collection box 36 through the discharge pipe 4 and the movable sleeve 37, preventing dust from overflowing from the discharge pipe 4 into the entire production workshop.
