Description

Technical Field

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

[0002] Magnetic powder is a kind of hard magnetic single-domain particle. It is made into magnetic slurry with adhesives, solvents, etc., and coated on the surface of plastic or metal substrate (support) to make magnetic recording materials such as magnetic tapes, disks, and magnetic cards. Magnetic powder is the core component of magnetic coatings and is the main factor that determines the magnetic properties of magnetic recording media. Magnetic powder has a great influence on the properties of magnetic recording materials. Therefore, there are certain requirements for magnetic powder: ① It should be larger than the saturation magnetization and coercive force; ② The particles are fine needle-shaped and uniform; ③ It has high dispersibility and filling properties in the magnetic slurry; ④ It is magnetically stable. It is difficult for magnetic powder to meet the above requirements at the same time. Commonly used magnetic powders are oxide magnetic powders and metal magnetic powders.

[0003] After searching, a Chinese patent discloses a magnetic powder recovery device, and its authorization announcement number is (CN214052088U), which includes a device main body, a feed inlet, a fixed bottom plate and a divider. A divider body is fixedly installed at the bottom end of the device main body, a divider block is fixedly installed on the top of the divider body, a divider is fixedly installed above the divider block, a rotating shaft is fixedly installed at the center of the divider, a superconducting magnet is fixedly installed on one side of the divider, a fixed block is fixedly installed on the inner wall of the device main body close to the power wheel, a torsion spring is fixedly installed at one end of the fixed block, and a scraper is fixedly installed at one end of the torsion spring.

[0004] This patented technology uses a scraper and a torsion spring. When the equipment is in use, the magnetic powder has a certain probability of sticking to the surface of the separator. The scraper will scrape the passing magnetic powder to the magnetic powder outlet, and the torsion spring will ensure that the scraper is always close to the surface of the separator. In actual use, the feed port cannot control the feed speed. After the material is put in, the material feeds faster and more concentrated. The separator cannot separate the magnetic powder in time and effectively. A small amount of magnetic powder is still taken away with the material, resulting in low magnetic powder recovery efficiency. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0024] Embodiment 1, as Figure 1-4 As shown, a magnetic powder recovery device comprises a collection chamber 1, a support box 2 is arranged in the middle of the inner cavity of the collection chamber 1, a driving motor 3 and a reducer 4 are installed inside the support box 2, the output shaft of the driving motor 3 is drivingly connected with the input shaft of the reducer 4, the driving shaft 5 of the reducer 4 passes through the upper surface of the support box 2 and a turntable 6 is fixedly installed coaxially, a magnetic attraction block 7 is fixedly installed on the right side of the upper surface of the support box 2, and the magnetic attraction block 7 is located below the right half of the turntable 6;

[0025] A feed hopper 8 is fixedly installed on the upper wall of the collecting chamber 1, and the outlet end of the feed hopper 8 is opposite to the upper surface of the right half of the turntable 6; a magnetic powder collection box 9 is arranged on the left side of the inner cavity of the collecting chamber 1, and a debris collection box 10 is arranged on the right side of the inner cavity of the collecting chamber 1.

[0026] Working principle:

[0027] When in use, first control the drive motor 3 to operate to drive the turntable 6 to rotate at a uniform speed, and evenly feed the material from the feed hopper 8 into the collecting chamber 1, so that the material evenly falls on the right half of the turntable 6. At this time, since a magnetic block 7 is provided under the right half of the turntable 6, the magnetic powder on the material will be adsorbed on the turntable 6, and other debris will be separated and thrown into the debris collection box 10 under the action of centrifugal force, and the magnetic powder on the turntable 6 will rotate with the turntable 6 to the left half away from the magnetic block 7. At this time, since there is no suction from the magnetic block, the magnetic powder will be thrown into the magnetic powder collection box 9 on the left side with the centrifugal force of the rotation of the turntable 6, thereby completing the separation and recovery of the magnetic powder.

[0028] Embodiment 2, as a further preferred embodiment of embodiment 1, a baffle 11 is fixedly installed in the middle of the upper wall of the inner cavity of the collection chamber 1, and the baffle 11 is located in the middle of the turntable 6. The baffle 11 can avoid dividing the upper part of the turntable 6 into a left half and a right half, thereby effectively avoiding the problem of scattering when the material enters the collection chamber 1 from the feed hopper 8, thereby affecting the separation and recovery effect of the magnetic powder.

[0029] Embodiment 3, as a further preferred embodiment of embodiment 1, two feed adjustment plates 12 are symmetrically installed in the feed hopper 8, and screw sliders 13 are installed below the feed adjustment plates 12. A bidirectional screw 14 is rotatably connected in the feed hopper 8 through a bearing, and the left and right halves of the bidirectional screw 14 have opposite thread rotation directions. The two screw sliders 13 are respectively connected to the left and right halves of the bidirectional screw 14 through threads, and one end of the bidirectional screw 14 extends to the outside of the feed hopper 8 and is fixedly connected with an adjustment knob 15. By rotating the adjustment knob 15 in the forward or reverse direction, the bidirectional screw 14 is driven to rotate, and then the two screw sliders 13 are driven to move closer to or away from each other.

[0030] Therefore, after the material with magnetic powder attached is put into the feed hopper 8, the two feed adjustment plates 12 can be controlled to move closer to or farther away from each other by rotating the adjustment knob 15 in the forward or reverse direction, thereby controlling the feed speed to prevent the material from piling up due to excessive feeding, thereby avoiding the situation where the magnetic powder in the material cannot be completely collected.

[0031] Embodiment 4, as a further preferred solution of embodiment 1, drawer openings are provided on both sides of the collection chamber 1, and the magnetic powder collection box 9 and the debris collection box 10 are slidably connected in the drawer openings. Therefore, after the separation and recovery of the magnetic powder are completed, the magnetic powder collection box 9 and the debris collection box 10 can be directly slid out along the drawer openings, so that the magnetic powder and debris can be quickly collected and processed.

[0032] Embodiment 5, as a further preferred solution of embodiment 1, a guide plate 16 is provided on the left side of the support box 2. The guide plate 16 facilitates the smooth falling of magnetic powder into the magnetic powder collecting box 9, thereby facilitating the subsequent collection of magnetic powder.

[0033] Embodiment 6, as a further preferred embodiment of embodiment 1, the four corners of the bottom of the collecting chamber 1 are fixedly connected with foot pads 17, and a viewing window 18 is provided on one side of the collecting chamber 1. The four foot pads 17 at the bottom of the collecting chamber 1 increase the buffering effect to prevent the collecting chamber 1 from shaking or deviating during use, and the viewing window 18 facilitates observation of the separation of the magnetic powder on the turntable 6, so as to timely adjust the feeding speed of the feeding hopper 8 and improve the efficiency of magnetic powder recovery.

[0034] Embodiment 7, as a further preferred embodiment of embodiment 1, the side of the turntable 9 close to the magnetic block 7 is arranged in a downward tilted state. The tilted setting of the turntable 9 is conducive to separating other debris, making it easier for the debris to fall into the debris collection box 10.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
