Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and more specifically, to a magnetic suction impurity removal device at the feed inlet of a crusher. Background Technology

[0002] Currently, in industries such as pharmaceuticals, daily chemicals, and food, pulverizers are machines that crush large solid raw materials to the required size. They achieve the purpose of pulverization through high-speed impact. Pulverizers utilize the high-speed relative motion between moving toothed discs to achieve pulverization through a combination of impact, friction, and mutual impact between the materials being pulverized and the toothed discs. During the pulverization process, the temperature of the pulverizing chamber shell will continuously rise. On the one hand, this can easily burn workers. On the other hand, since the processed products are mostly food and other items, high temperatures can affect the quality of the pulverized materials and may even burn them.

[0003] In actual use, before the medicinal materials are pulverized, they may contain some iron impurities. Once iron impurities are mixed in and enter the medicinal materials, they can cause serious wear to the pulverizing disc, reduce pulverizing efficiency and increase energy consumption; in severe cases, they can cause sparks to be generated by collision, leading to safety accidents or equipment explosions, which will affect the pulverizing efficiency of the pulverizer. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a magnetic suction impurity removal device for the feed inlet of a crusher to solve the problems mentioned in the background art.

[0008] By adopting the above technical solution: by setting up two servo motors and permanent magnet rollers, and by combining diverting plates and guide plates to divert the medicinal materials, the medicinal materials are magnetically separated to remove impurities. At the same time, a scraper is used to clean the surface of the permanent magnet rollers, so that the tray can collect iron impurities in a concentrated manner.

[0009] As a further description of the above technical solution: the feeding mechanism includes a servo motor three, one side of which is fixedly connected to the outside of the feeding hopper, and a rotating roller is fixedly connected to the output end of the servo motor three. Multiple support rods one are fixedly connected to the outside of the rotating roller, and a support rod two is fixedly connected to one end of each support rod one.

[0010] By adopting the above technical solution, multiple support rods 1 and 2 are used to assist the medicinal materials gathered inside the feed hopper to enter the interior of the crushing chamber shell along the bottom of the feed hopper, thereby avoiding the accumulation of medicinal materials inside the feed hopper and maintaining the continuity of the feed of medicinal materials.

A diversion magnetic separation mechanism is provided inside the feed hopper 4. A feeding mechanism is provided inside the feed hopper 4. The servo motor 13 drives the crushing blade disk 12 to cooperate with the fixed crushing disk 7 to crush the medicinal materials that enter the crushing chamber housing 2. The bolts 10 and the nut 11 are used to fasten the card seat 8, which facilitates the cleaning of the inside of the crushing chamber housing 2.

[0021] Reference Figure 4 and Figure 5 As shown, the diversion magnetic separation mechanism includes a diversion plate 14, the outer side of which is fixedly connected to the inner side of the feed hopper 4. Two guide plates 15 are fixedly connected to the inner side of the feed hopper 4, symmetrically distributed on both sides of the diversion plate 14. Two fixing plates 16 are fixedly connected to the inner side of the feed hopper 4, and a scraper 17 is fixedly connected to one side of the fixing plate 16. A drop hole 18 is opened on the inner side of the scraper 17. Two servo motors 19 are fixedly connected to the outer side of the feed hopper 4, and a permanent magnet roller 20 is fixedly connected to the output end of the servo motors 19. The outer side of the permanent magnet roller 20 is rotatably connected to the inner side of the feed hopper 4. A tray 21 is provided on one side of the fixed plate 16. The outer side of the tray 21 is slidably connected to the inner side of the feed hopper 4. A collection trough is provided on the inner side of the tray 21. The diversion plate 14 is used to divert the medicinal materials, and with the inclined guidance of the guide plate 15, the medicinal materials can be diverted and magnetically removed at the same time, which improves the efficiency of removing impurities from the medicinal materials. At the same time, the iron impurities adsorbed on the surface of the permanent magnet roller 20 can be scraped, cleaned and collected, maintaining the continuity of magnetic impurity removal by the permanent magnet roller 20.

[0022] Reference Figure 4 and Figure 6As shown, the feeding mechanism includes a servo motor 22. One side of the servo motor 22 is fixedly connected to the outside of the feeding hopper 4. A rotating roller 23 is fixedly connected to the output end of the servo motor 22. Multiple support rods 24 are fixedly connected to the outside of the rotating roller 23. Support rods 25 are fixedly connected to one end of each support rod 24. An acute angle greater than 0 degrees and less than 90 degrees is formed between the central axis of the support rod 24 and the central axis of the support rod 25. Combined with the rotation of the servo motor 22 and the rotating roller 23, the medicinal materials inside the feeding hopper 4 are continuously fed into the crushing chamber shell 2.

[0023] The working principle of this utility model is as follows: Before pulverizing the medicinal materials, the materials are first fed from the top of the feed hopper 4. The materials are then diverted by a diversion plate 14 located inside the feed hopper 4. After diversion, the materials are guided downwards by the inclined guide plate 15 and approach the corresponding permanent magnet roller 20 at the bottom. Two servo motors 19 are then activated to drive the permanent magnet roller 20 to rotate, causing the permanent magnet roller 20 to magnetically attract iron impurities mixed inside the materials. Under the magnetic attraction and rotation of the permanent magnet roller 20, the materials are then moved towards the bottom of the feed hopper 4. The impurities fall and accumulate, and the iron impurities attracted by the permanent magnet roller 20 move to one side of the scraper 17 as the permanent magnet roller 20 rotates. As the scraper 17 scrapes the surface of the permanent magnet roller 20, the iron impurities attracted by the permanent magnet roller 20 accumulate and fall downwards. Then, the iron impurities fall downwards through the drop hole 18 into the collection groove on the surface of the tray 21 for accumulation. After being magnetically removed, the medicinal materials will accumulate inside the feed hopper 4. Then, the servo motor 3 22 is started to drive the roller 23, multiple support rods 1 24 and support rod 25 to rotate, as shown in the attached figure. Figure 6 As shown, support rod 25 is inclined at the end of support rod 24. As support rod 24 and support rod 25 rotate, the medicinal materials inside the feed hopper 4 are scraped downwards to assist in feeding. Then the medicinal materials enter the interior of the crushing chamber housing 2. Servo motor 13 is started to drive the crushing blade disk 12 to rotate, and cooperates with the fixed crushing disk 7 to crush the medicinal materials that have entered the crushing chamber housing 2. After that, the crushed medicinal materials are discharged through the discharge hole 3 inside the crushing chamber housing 2 and the base box 1. Finally, the nut 11 can be rotated at one end of the bolt 10, and the cover 6 and the card seat 8 can be opened by deflecting to one side through the fixed seat 5, so as to facilitate the cleaning of the interior of the crushing chamber housing 2 and complete the magnetic crushing and impurity removal of the medicinal materials.
