Description

Technical Field

[0001] The utility model relates to the technical field of metal sorting, in particular to a metal magnetic rotation sorting device. Background Art

[0002] Waste pure titanium shavings are non-magnetic and can only be pressed into balls after being crushed and dried. However, the waste material contains magnetic substances that can affect the quality of the titanium balls. Therefore, magnets are installed at the outlet of the dried material to absorb and filter out the magnetic substances.

[0003] Because magnets have a limited capacity for adsorption, they require frequent cleaning, resulting in low removal efficiency. Furthermore, once the magnets have reached a certain capacity, magnetic material can be easily lost. Therefore, improving the efficiency and quality of magnetic material removal has become a pressing issue for those skilled in the art. Utility Model Content

[0004] In order to solve the technical problems in the background technology, the utility model discloses a metal magnetic rotation sorting device.

[0005] The utility model provides a metal magnetic rotation sorting device, comprising:

[0006] The box body has a material inlet at the top and a magnetic material outlet and a non-magnetic material outlet arranged at intervals at the bottom;

[0007] The cylinder is set in the box body, with its axis arranged horizontally and driven by a reduction motor to rotate along its axis; the upper end of the cylinder is facing the material inlet;

[0008] The magnet is fixedly mounted in the box and arranged inside the cylinder; the magnet is located near the non-magnetic material outlet, one end of the magnet extends to just below the material inlet, and the other end extends to a position away from the non-magnetic material outlet;

[0009] The outlet for magnetic materials is located away from the magnets.

[0010] After the material enters the box from the material inlet, it falls on the cylinder. Titanium shavings have no magnetism and cannot be attracted by the magnet, so they will slide down under the action of gravity and flow out from the non-magnetic material outlet; the magnetic material is adsorbed on the surface of the cylinder under the action of the magnet; as the cylinder rotates, the magnetic material on the cylinder rotates to the area where it is separated from the magnet, the adsorption force of the magnet disappears, the magnetic material separates from the cylinder, and falls from the magnetic material outlet; the above setting realizes the automatic separation of titanium and magnetic material in waste pure titanium shavings, and does not require regular cleaning, so the removal efficiency and quality of magnetic material are relatively high.

[0011] In order to achieve stable separation of titanium and magnetic materials, further improvements are as follows: the magnet is in a semi-circular shape that is symmetrical in the upper and lower parts; a first guide plate and a second guide plate that are connected to each other are provided in the box; the first guide plate and the second guide plate both extend downward from the connection; the lower end of the first guide plate faces the non-magnetic material outlet; the lower end of the second guide plate faces the magnetic material outlet; the connection between the first guide plate and the second guide plate is located near the non-magnetic material outlet.

[0012] Since magnetic materials are easily adsorbed on the cylinder and are not easy to fall off even if they are far away from the magnet, based on this, a further improvement is that: one side of the box where the magnet is provided is set as a magnetic cavity, and the other side is set as a non-magnetic cavity; the non-magnetic cavity is provided with a scraper against the outer wall of the cylinder.

[0013] If the scraper is set below the horizontal center line of the cylinder, the magnetic material will be scraped off by the scraper before it falls freely, which will increase the resistance to the rotation of the cylinder and make the scraper wear faster; if the scraper is set above the horizontal center line of the cylinder and away from the horizontal center line, the scraped magnetic material will still be adsorbed on the cylinder; if the scraper is set at a position flush with the horizontal center line of the cylinder, its position accuracy and position stability requirements are high, and the scraper is likely to fall off the cylinder. Based on this, further improvement is: the scraper is set above the horizontal center line of the cylinder and close to the horizontal center line.

[0014] In order to improve the scraping efficiency of the scraper, a further design is: the scraper is arranged at an angle, and its lower end is in line contact with the cylinder; the scraper gradually moves away from the cylinder from bottom to top.

[0015] The magnetic material scraped off by the scraper will extend toward the scraper. In order to ensure that the magnetic material falls off immediately, a further design is that the lower end surface of the scraper is arranged horizontally.

[0016] In order to prevent the material from entering the non-magnetic cavity by mistake after entering the material inlet, a further improvement is that the material inlet is arranged obliquely, with its lower end pointing to the magnetic cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] like Figure 1 As shown, the utility model discloses a metal magnetic rotation sorting device, comprising a box 1, a material inlet 11 is provided at the center of the top, and a magnetic material outlet 12 and a non-magnetic material outlet 13 are provided at the lower end on both sides of the box 1.

[0024] Housing 1 houses a cylindrical barrel 2, oriented horizontally along its axis. Coaxially arranged shafts are located at each end of barrel 2, connected for rotation via bearing units mounted on housing 1. One of the shafts is fixedly connected to the drive shaft of a reduction motor 3 via a coupling, enabling barrel 2 to rotate along its axis under the drive of reduction motor 3.

[0025] like Figure 2 As shown, the top of the cylinder 2 is located directly below the material inlet 11 , and the magnetic material outlet 12 and the non-magnetic material outlet 13 are both located obliquely below both sides of the cylinder 2 .

[0026] A semi-annular magnet 4 is also provided in the cylinder 2, and the magnet 4 is symmetrical in structure. The left and right ends of the magnet 4 pass through the cylinder 2 and are fixedly mounted on the box 1.

[0027] The magnet 4 is coaxially arranged with the cylinder 2 and is located near the inner wall of the cylinder 2 and near the non-magnetic material outlet 13, so that one end of the magnet 4 extends directly below the material inlet 11 and the other end extends away from the non-magnetic material outlet 13. The side of the box 1 where the magnet 4 is located is defined as a magnetic cavity 14, and the other side is defined as a non-magnetic cavity 15.

[0028] The lower end of the housing 1 is provided with a first guide plate 5 and a second guide plate 6, which are connected to each other. Both the first guide plate 5 and the second guide plate 6 extend downward from the connection. The lower end of the first guide plate 5 faces the non-magnetic material outlet 13, while the lower end of the second guide plate 6 faces the magnetic material outlet 12. The connection between the first and second guide plates 5 and 6 is located within the magnetic cavity 14 near the non-magnetic material outlet 13. This ensures that magnetic material will not fall until it passes over the first guide plate 5, preventing it from accidentally entering the non-magnetic material outlet 13.

[0029] Since some magnetic materials are easily adsorbed on the cylinder 2 and are not easy to fall off even if they are far away from the magnet 4, a scraper 7 is provided in the non-magnetic cavity 15 to abut against the outer wall of the cylinder 2. The scraper 7 is provided above the horizontal center line of the cylinder 2 and close to the horizontal center line. The reasons for such design are as follows: if the scraper 7 is provided below the horizontal center line of the cylinder 2, the magnetic materials will be scraped off by the scraper 7 before they fall freely, which will increase the resistance to the rotation of the cylinder 2 and make the scraper 7 wear faster; if the scraper 7 is provided above the horizontal center line of the cylinder 2 and away from the horizontal center line, the scraped magnetic materials will still be adsorbed on the cylinder 2; if the scraper 7 is provided at a position flush with the horizontal center line of the cylinder 2, the requirements for its position accuracy and position stability are high, and the scraper 7 is prone to detachment from the cylinder 2.

[0030] like Figure 3 As shown, the scraper 7 is arranged at an angle, and its lower end is in line contact with the cylinder 2; the scraper 7 gradually moves away from the cylinder 2 from bottom to top. Line contact can improve scraping efficiency and quality.

[0031] The lower end surface of the scraper 7 is arranged horizontally, so that the magnetic material scraped off by the scraper 7 will extend toward the scraper 7 and can fall off immediately.

[0032] The material inlet 11 is arranged at an angle, with its lower end pointing toward the magnetic cavity 14 , so as to prevent the material from mistakenly entering the non-magnetic cavity 15 when entering the box body 1 .

[0033] After the material enters the box 1 from the material inlet 11, it falls on the cylinder 2. The titanium shavings have no magnetism and cannot be adsorbed by the magnet 4. Therefore, they will slide down under the action of gravity and flow out from the non-magnetic material outlet 13; the magnetic material is adsorbed on the surface of the cylinder 2 under the action of the magnet 4; as the cylinder 2 rotates, when the magnetic material on the cylinder 2 rotates to the area where it is separated from the magnet 4, the adsorption force of the magnet 4 disappears, the magnetic material is separated from the cylinder 2, and falls from the magnetic material outlet 12; the above arrangement realizes the automatic separation of titanium and magnetic material in waste pure titanium shavings, and does not require regular cleaning, so the removal efficiency and quality of the magnetic material are relatively high.

[0034] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
