Description

Technical Field

[0001] This utility model relates to a metal separator and belongs to the field of metal separation technology. Background Technology

[0002] Chemical fibers (also known as synthetic fibers) are fibrous materials made by processing natural or synthetic polymers through chemical processes. Chemical fiber raw materials can be divided into synthetic fiber raw materials (such as polyester, nylon, and polypropylene) and recycled fiber raw materials (such as wood pulp, bamboo pulp, and waste cotton). These raw materials are transformed into fibers through different chemical and physical processes, and ultimately processed into various textiles, widely used in clothing, home furnishings, and industrial fields.

[0003] In the production process of chemical fibers, the raw materials first need to be processed into powder or granules. However, metal impurities may be introduced into the raw materials during recycling and processing. The metal components can affect the performance, quality, and processing of chemical fibers. Metal separation devices are usually required to separate the metal components. Here, Chinese invention patent with announcement number CN108176503A discloses a PVC particle metal separator, which includes a feeding mechanism and a material collector. A metal separator is set between the feeding mechanism and the material collector. The metal separator is equipped with a central transmitting coil, a left receiving coil, and a right receiving coil. A rotating shaft is connected to the lower part of the metal separator. A filter screen is set around the rotating shaft, and a material collector is set below the filter screen. The invention includes a metal separator between the feeding mechanism and the material collector. A rotating shaft is connected to the lower part of the metal separator, and a filter screen is arranged around the rotating shaft. A material collector is located below the filter screen. This design is reasonable and can remove metal impurities. The filter screen around the rotating shaft has at least two layers, each with a different mesh diameter, allowing for the filtration of different PVC particles. This improves production efficiency, purity, and yield. However, in existing technologies, when the chemical fiber raw material is in powder form, both the raw material and metal components can pass through the filter screen, affecting the reliability of metal component separation.

[0004] Therefore, a metal separator is needed to improve the reliability of metal component separation. Utility Model Content

Detailed Implementation

[0026] like Figure 1-6As shown, a metal separator in this embodiment includes a housing 1. The top of the housing 1 has an inlet 2, and the bottom of the housing 1 has a first outlet 3 and a second outlet 4. The first outlet 3 and the second outlet 4 are arranged side-by-side, specifically, the first outlet 3 and the second outlet 4 are distributed left and right. A rotating drum 5 is installed inside the housing 1. The rotating drum 5 is horizontally arranged, specifically, the axis of the rotating drum 5 is parallel to the front-back direction. Both ends of the rotating drum 5 are sealed to the inner walls of both sides of the housing 1. The first outlet 3 and the second outlet 4 are located on both sides of the axis of the rotating drum 5. 4. Symmetrical about the axis of the rotating drum 5, the feed inlet 2 and the first discharge outlet 3 are located on the same side of the axis of the rotating drum 5. One end of the rotating drum 5 is connected to a drive source 6. The drive source 6 is located outside the housing 1. The drive source 6 is used to drive the rotating drum 5 to rotate. The drive source 6 is a motor. Multiple magnet blocks 7 are arranged inside the rotating drum 5. The multiple magnet blocks 7 are evenly distributed circumferentially around the axis of the rotating drum 5. A scraper 8 is arranged inside the housing 1. The scraper 8 is located on the side of the rotating drum 5 away from the feed inlet 2. The scraper 8 is fixedly arranged on the housing 1. The scraper 8 is in contact with the outer peripheral wall of the rotating drum 5. Specifically, the scraper 8 is located on the left side of the rotating drum 5.

[0027] During operation, the chemical fiber raw material is conveyed from the feed inlet 2 into the housing 1. The raw material in the housing 1 falls onto the outer wall of the rotating drum 5 under its own weight. At the same time, the motor starts, causing the rotating drum 5 to rotate. At this time, the metal components in the raw material are attracted to the outer wall of the rotating drum 5 by the magnet 7, while the other parts of the raw material fall off the outer wall of the rotating drum 5 and are finally discharged from the first discharge port 3. As the rotating drum 5 continues to rotate, the metal components attracted to the outer wall of the rotating drum 5 rotate to the scraper 8. The scraper 8 scrapes off the metal components attracted to the outer wall of the rotating drum 5 and finally discharges them from the second discharge port 4. Here, the metal components mainly refer to ferromagnetic metals such as iron, cobalt, and nickel. Compared with the existing technology, there is no need to use a filter screen, which improves the reliability of metal component separation.

[0028] The box 1 is provided with a first partition 9, which is located below the rotating drum 5 and between the first discharge port 3 and the second discharge port 4. The first partition 9 is fixedly installed at the bottom of the box 1. The first partition 9 prevents the raw material from being discharged from the second outlet when it falls down from the rotating drum 5.

[0029] The housing 1 is provided with a second partition 10, which is located directly above the rotating drum 5. The second partition 10 is located on the side of the feed inlet 2 close to the axis of the rotating drum 5. Specifically, the second partition 10 is located on the left side of the feed inlet 2. The second partition 10 prevents the raw materials conveyed from the feed inlet 2 into the housing 1 from falling directly to the left side of the rotating drum 5 and thus preventing normal metal component separation.

[0030] A fixing plate 11 is provided inside the housing 1. The fixing plate 11 is located between the feed inlet 2 and the rotating drum 5. The fixing plate 11 is arranged at an angle. Specifically, the top of the fixing plate 11 is located on the right side of the bottom of the fixing plate 11. The fixing plate 11 is located on the side of the second partition 10 near the feed inlet 2. A flow equalization plate 12 is fixedly installed on the fixing plate 11. The flow equalization plate 12 is located between the fixing plate 11 and the second partition 10. The flow equalization plate 12 is provided with flow equalization holes 13. The flow equalization plate 12 is inverted V-shaped. After the raw material is conveyed into the housing 1 from the feed inlet 2, the raw material falls onto the flow equalization plate 12. The raw material on the flow equalization plate 12 falls onto the rotating drum 5 through the flow equalization holes 13. Moreover, the raw material on the flow equalization plate 12 also moves in the front-back direction along the inclined surface at the top of the flow equalization plate 12, thereby improving the uniformity of the raw material falling onto the rotating drum 5 and facilitating the adsorption of metal components on the outer peripheral wall of the rotating drum 5.

[0031] The rotating cylinder 5 has an opening at one end away from the drive source 6. A support plate 14 is provided inside the rotating cylinder 5. The support plate 14 is coaxially arranged with the rotating cylinder 5 and is fixedly installed on the inner wall of the housing 1. The open end of the rotating cylinder 5 is sleeved on the support plate 14. The support plate 14 is in close contact with the inner wall of the rotating cylinder 5. Specifically, the inner diameter of the rotating cylinder 5 is equal to the diameter of the support plate 14. During the rotation of the rotating cylinder 5, the cooperation between the rotation and the support plate 14 achieves the effect of supporting the rotating cylinder 5.

[0032] A fixed shaft 15 is provided inside the rotating drum 5. The fixed shaft 15 is coaxially fixed on the support plate 14. An elastic rod 16 is provided on the fixed shaft 15. Multiple elastic rods 16 are provided, and multiple magnet blocks 7 are distributed alternately. During the rotation of the rotating drum 5, the magnet blocks 7 intermittently strike the elastic rods 16, causing the rotating drum 5 to vibrate. When the metal component is adsorbed on the outer peripheral wall of the rotating drum 5 and the raw material is clamped between the metal component and the rotating drum 5, the vibration facilitates the relative movement between the metal component and the raw material, which facilitates the separation of the metal component from the raw material and direct adsorption on the outer peripheral wall of the rotating drum 5, thereby improving the reliability of the rotating drum 5 in adsorbing the metal component.

[0033] In summary, during the rotation of the rotating drum 5, the magnetic block 7 causes the drum 5 to adsorb the metal components in the raw material, allowing the raw material to be discharged from the first discharge port 3. The metal components are then scraped off by the scraper 8 and discharged from the second discharge port 4. This eliminates the need for a filter screen to separate the metal components, thus improving the reliability of metal separation.

[0034] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
