Description

Technical Field

[0001] This utility model relates to the field of permanent magnet screening technology, and in particular to a scraper-type fully automatic permanent magnet iron separator. Background Technology

[0002] In numerous industrial sectors such as food processing, pharmaceutical manufacturing, chemical production, and mineral screening, metallic magnetic impurities mixed in raw materials can severely affect product quality, damage production equipment, and even cause safety accidents. Therefore, permanent magnet separators are necessary for iron removal from raw materials. Permanent magnet separators, with their advantages of not requiring continuous power supply, stable operation, and energy saving, have become the mainstream iron removal equipment. Their core working component is a permanent magnet rod, which utilizes the strong magnetism of permanent magnet materials to adsorb metallic magnetic substances in the raw materials, thereby purifying them. After the permanent magnet rod operates continuously for a period of time, its surface gradually adsorbs a large amount of metallic magnetic impurities. These impurities form a magnetic deposit layer on the surface of the permanent magnet rod, requiring surface cleaning. Existing permanent magnet rods often use scrapers to scrape off the magnetic material, but this method lacks collection of the scraped magnetic material. When the scraper removes the magnetic material from the permanent magnet rod, this magnetic material, freed from the magnetic field's binding force, falls directly, causing the fallen magnetic material to scatter again, resulting in secondary contamination of the raw materials. This renders the initial iron removal work ineffective and seriously affects product quality. Therefore, this utility model proposes a scraper-type fully automatic permanent magnet separator. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art that there is a lack of collection of scraped magnetic materials. When the scraper scrapes the magnetic materials off the permanent magnet rod, these magnetic materials, which are freed from the magnetic field of the permanent magnet rod, will fall directly. This causes the fallen magnetic materials to scatter again, resulting in secondary pollution of the raw materials. This renders the previous iron removal work useless and seriously affects the product quality. The invention proposes a scraper-type fully automatic permanent magnet iron separator.

[0004] The technical solution of this utility model is as follows: A scraper-type fully automatic permanent magnet iron separator includes: a set of frames, a support plate fixedly installed at the upper end of the frames, a stirring cylinder arranged between the frames, and the stirring cylinder located directly below the support plate; a mounting plate fixedly installed on the upper surface of the support plate, a motor fixedly installed on the upper surface of the mounting plate, the output end of the motor passing through the mounting plate and extending to connect to a stirring rod, and a stirring blade fixedly installed at the lower end of the stirring rod; a fixing plate set on the upper surface of the support plate, the fixing plate being located on one side of the mounting plate, and an iron removal component for removing iron from the inside of the stirring cylinder being provided on the upper surface of the fixing plate; a second electric push rod fixedly installed on one side of the frame, the output end of the second electric push rod passing through the frame and extending to connect to a storage box, and a scraping component for cleaning the iron removal component being provided directly above the storage box.

[0005] Optionally, the iron removal assembly includes a support plate fixedly mounted on the upper surface of the fixed plate. A guide groove is provided on one side of the support plate, and a guide block is slidably disposed inside the guide groove. A first electric push rod is fixedly mounted on the upper surface of the fixed plate. The output end of the first electric push rod is fixedly connected to the bottom surface of the guide block, and a permanent magnet is fixedly disposed on the other end of the guide block.

[0006] Optionally, the scraping assembly includes two sets of guide bars slidably disposed between the support plates. A rack is fixedly disposed on one side of each guide bar, and a gear is meshed between the racks. The gear is rotatably connected to the support plate. A scraper is fixedly disposed at one end of each rack, and a scraping groove is formed on one side of the scraper.

[0007] Optionally, the scraping assembly further includes a card strip fixedly disposed above the storage box, wherein a card frame is slidably disposed inside the card strip, and the upper surface of the card frame is fixedly connected to the bottom surface of the rack.

[0008] Optionally, a locking block is fixedly provided at the output end of the second electric push rod, and a locking seat is fixedly provided on one side of the storage box.

[0009] Optionally, a first infrared sensor is fixedly installed on one side of the support plate.

[0010] Optionally, a second infrared sensor is fixedly mounted on one side of the frame.

[0011] Optionally, the inner wall of the support plate is provided with a sliding groove, which is slidably connected to the guide strip.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This utility model uses a scraping assembly that includes a scraper with a scraping groove, a rack, a gear, and a guide rail block structure. The scraper position can be adjusted according to the movement of the permanent magnet rod. At the same time, the storage box is set directly below the scraper and its position can be adjusted by a second electric push rod. After the scraper scrapes the magnetic material off the permanent magnet rod, the scraped magnetic material can fall directly into the storage box below, avoiding the scraper scraping the magnetic material into the raw material, preventing the magnetic material from re-scattering and causing secondary pollution of the raw material, ensuring the effect of the initial iron removal operation, and thus improving product quality.

[0014] Furthermore, this utility model allows for the detachable connection between the output end of the second electric push rod and the slot of the storage box via a locking block, enabling the centralized storage of magnetic materials. After the magnetic materials are collected in the storage box, the storage box can be disassembled for cleaning, thus improving cleaning efficiency. Attached Figure Description

[0032] Example

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the scraper-type fully automatic permanent magnet separator proposed in this utility model includes: a set of frames 1, a second infrared sensor 16 fixedly installed on one side of the frame 1, the second infrared sensor 16 is located on one side of the storage box 11, and is used to detect the moving position of the storage box 11; a support plate 2 is fixedly installed at the upper end of the frame 1, and a sliding groove 17 is opened on the inner wall of the support plate 2, and two sets of sliding grooves 17 are provided. The sliding grooves 17 are slidably connected to the guide strip 121, which can provide guidance for the guide strip 121 and make its movement more stable; a stirring cylinder 3 is arranged between the frames 1, and the stirring cylinder 3 is located directly below the support plate 2, and is used to place the raw materials inside the stirring cylinder 3 for uniform stirring.

[0034] Furthermore, an mounting plate 4 is fixedly installed on the upper surface of the support plate 2, and a motor 5 is fixedly installed on the upper surface of the mounting plate 4. The output end of the motor 5 passes through the mounting plate 4 and extends to connect to a stirring rod 6. A stirring blade 7 is fixedly installed at the lower end of the stirring rod 6. By driving the stirring blade 7 at the lower end of the stirring rod 6 through the motor 5, the raw materials can be stirred evenly, making the iron removal more uniform. A fixing plate 8 is located on the upper surface of the support plate 2, and the fixing plate 8 is located on one side of the mounting plate 4.

[0035] Secondly, a second electric push rod 10 is fixedly installed on one side of the frame 1. A locking block 13 is fixedly provided at the output end of the second electric push rod 10. The output end of the second electric push rod 10 passes through the frame 1 and extends to connect to the storage box 11. The storage box 11 can be moved by the second electric push rod 10 to avoid obstructing the permanent magnet rod 95. A locking seat 14 is fixedly provided on one side of the storage box 11. The locking block 13 and the locking seat 14 make it easy to remove and clean the storage box 11.

[0036] like Figure 1 and Figure 4 As shown, the upper surface of the fixed plate 8 is provided with an iron removal component 9 for removing iron from the inside of the mixing drum 3. The iron removal component 9 includes a support plate 91 fixedly installed on the upper surface of the fixed plate 8. A first infrared sensor 15 is fixedly installed on one side of the support plate 91. The first infrared sensor 15 can detect the position of the permanent magnet rod 95. A guide groove 92 is opened on one side of the support plate 91. A guide block 93 is slidably installed inside the guide groove 92, which can make the guide block 93 move stably in the direction of the guide groove 92. A first electric push rod 94 is fixedly installed on the upper surface of the fixed plate 8. The output end of the first electric push rod 94 is fixedly connected to the bottom surface of the guide block 93. The other end of the guide block 93 is fixedly installed with a permanent magnet rod 95. The first electric push rod 94 can push the permanent magnet rod 95 into the interior of the raw material for iron removal.

[0037] like Figure 1 and Figure 5 As shown, a scraping assembly 12 for cleaning the iron removal assembly 9 is provided directly above the storage box 11. The scraping assembly 12 includes two sets of guide bars 121 slidably disposed between the support plates 2. A rack 122 is fixedly disposed on one side of each guide bar 121. The guide bars 121 can guide the rack 122 to move stably. A gear 123 is meshed between the racks 122. The gear 123 is rotatably connected to the support plate 2 through a bearing. A scraper 124 is fixedly disposed at one end of the rack 122. A scraping groove 125 is opened on one side of the scraper 124, which can scrape off the magnetic material on the surface of the permanent magnet rod 95.

[0038] Furthermore, the scraping assembly 12 also includes a clip 126 fixedly disposed above the storage box 11. A clip frame 127 is slidably disposed inside the clip 126. The upper surface of the clip frame 127 is fixedly connected to the bottom surface of the rack 122. The clip 126 and the clip frame 127 enable the storage box 11 to move the rack 122 and facilitate the removal of the storage box 11.

[0039] The working principle of this embodiment is as follows: First, the raw material to be removed from iron is poured into the mixing drum 3. The motor 5 fixed on the mounting plate 4 on the upper surface of the support plate 2 is started to run. The output end of the motor 5 drives the stirring rod 6 that passes through the mounting plate 4 to rotate. The stirring blade 7 at the lower end of the stirring rod 6 rotates in the mixing drum 3 to fully stir the raw material, so that the magnetic substances in the raw material are evenly dispersed, which is convenient for the subsequent iron removal component 9 to adsorb.

[0040] Subsequently, the first electric push rod 94 on the upper surface of the fixed plate 8 is activated, pushing the guide block 93 to slide downward in the guide groove 92 of the support plate 91, causing the permanent magnet rod 95 at the other end of the guide block 93 to gradually extend into the raw material in the mixing drum 3. During the descent of the permanent magnet rod 95, the first infrared sensor 15 monitors the position of the permanent magnet rod 95 in real time to ensure that it can be accurately inserted into the raw material at the appropriate depth. The permanent magnet rod 95 uses its own magnetism to adsorb the magnetic substances in the raw material. After adsorption for a certain period of time, the first electric push rod 94 drives the guide block 93 and the permanent magnet rod 95 to move upward, detaching from the raw material and completing one iron removal adsorption operation.

[0041] When the permanent magnet rod 95 moves upward to the designated position, the second electric push rod 10 is activated. The output end of the second electric push rod 10 drives the storage box 11 to move directly below the permanent magnet rod 95. The storage box 11 drives the rack 122 to move via the locking strip 126 and the locking frame 127. The rack 122 meshes with the gear 123, thereby adjusting the scraper 124 to move horizontally relative to the ground. It also slides inside the slide groove 17 via the guide strip 121, ensuring the stability of the scraper 124's movement. When the scraper groove 125 on the scraper 124 is moved directly below the permanent magnet rod 95, the storage box 11 is positioned directly below the permanent magnet rod 95, enabling it to collect magnetic materials.

[0042] Then, the first electric push rod 94 is activated to drive the permanent magnet rod 95 to move vertically downward. At this time, since the storage box 11 is located directly below the scraper 124, the permanent magnet rod 95 comes into contact with the scraper groove 125 on the scraper 124 during the vertical downward movement, scraping the magnetic material on the outer wall of the permanent magnet rod 95 into the storage box 11, effectively preventing the magnetic material from falling back into the raw material in the mixing drum 3 and preventing secondary contamination of the raw material.

[0043] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
