Description

Technical Field

[0001] The invention belongs to the technical field of separating solid materials from solid materials, and particularly relates to an alloy powder magnetic filtration device. Background Art

[0002] Cobalt-molybdenum alloys are typically used in high-temperature or high-strength applications, such as aerospace or chemical equipment. The mixing of cobalt and molybdenum alloys requires a long mixing process, and the mixing of cobalt-molybdenum alloys is usually completed in mixing equipment.

[0003] However, cobalt-molybdenum alloy has a high hardness, especially in powder form. During high-speed mixing or long-term stirring, friction with the inner wall of the mixing equipment may cause ferromagnetic impurities to fall off. Even after long-term use of the mixing equipment, scratches or fatigue cracks may appear on the inner wall of the mixing equipment, further increasing the risk of ferromagnetic impurities falling off.

[0004] If ferromagnetic impurities are doped into cobalt-molybdenum alloy, the composition, microstructure and properties of the alloy will change, including changes in mechanical properties, corrosion resistance, heat resistance and wear resistance. Therefore, there is a defect that the performance of cobalt-molybdenum alloy is reduced. Summary of the Invention

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] Please also refer to Figures 1 to 9 The alloy powder magnetic filtration device of the present invention is described. An alloy powder magnetic filtration device includes a receiving barrel 10, a separation unit 20, and a discharge unit 30; the separation unit 20 includes a separation barrel 201 disposed on the top of the receiving barrel 10, a separation frame 202 disposed in the separation barrel 201, and a magnetic attraction component penetrated by the separation frame 202, wherein the inner diameter of the separation barrel 201 gradually decreases from top to bottom, and the bottom end of the separation barrel 201 extends into the receiving barrel 10, and the magnetic attraction component includes multiple groups of magnetic attraction mechanisms distributed in the vertical direction, with adjacent groups of magnetic attraction mechanisms staggered, and each group of magnetic attraction mechanisms includes multiple magnet rods 203 distributed in sequence, with the axial direction of the magnet rods 203 perpendicular to the plate surface of the separation frame 202; the discharge unit 30 includes a storage barrel 301 disposed above the separation unit 20, and a valve 3011 is provided at the bottom of the storage barrel 301.

[0048] Compared with the prior art, the alloy powder magnetic filtration device provided in this embodiment is different from the prior art. After the valve 3011 is opened, the alloy powder in the storage barrel 301 enters the separation barrel 201. When the alloy powder passes through the magnet rods 203, the alloy powder falls from the gap between two magnet rods 203 into the next row of magnet rods 203, and the alloy powder falls just above the next row of magnet rods 203, so that the alloy powder is in full contact with the magnet rods 203, thereby causing ferromagnetic impurities to be adsorbed on the periphery of the magnet rods 203, reducing the content of ferromagnetic impurities in the alloy powder, thereby improving the performance of the alloy powder.

[0049] In some embodiments, see Figures 1 to 3 The material receiving cylinder 10 includes a first splicing block 101 fixed to the separation cylinder 201 and a second splicing block 102 arranged relative to the first splicing block 101. The first splicing block 101 and the second splicing block 102 are detachably connected; the first splicing block 101 and the second splicing block 102 form a material receiving area, and a material receiving box 40 is placed in the material receiving area.

[0050] The separation cylinder 201 includes a first splicing arc 2011 fixed to the first splicing block 101 and a second splicing arc 2012 arranged relative to the first splicing arc 2011. The first splicing arc 2011 and the second splicing arc 2012 are detachably connected, and the top of the second splicing block 102 abuts against or is detachably connected to the outer wall of the second splicing arc 2012.

[0051] The outer wall of the magnet rod 203 is provided with a storage cavity 2031, and an embedded block 2032 is slidably connected to the storage cavity 2031. An elastic member 2033 is fixed between the inner wall of the storage cavity 2031 and the embedded block 2032. The elastic member 2033 has a pre-tightening force that allows the embedded block 2032 to be inserted into the embedded groove 2022. The end of the embedded block 2032 facing away from the elastic member 2033 is set to an elliptical shape. The separation frame 202 is provided with a through hole 2021 for the magnet rod 203 to pass through, and the inner wall of the through hole 2021 is provided with an embedded groove 2022 that is plugged into and adapted to the embedded block 2032.

[0052] It should be noted that the elastic member 2033 is a spring and the magnet rod 203 is a neodymium magnet.

[0053] After the alloy powder passes through the magnet rod 203, the magnet rod 203 absorbs the ferromagnetic impurities in the alloy powder through magnetic force, and the purified alloy powder falls into the receiving box 40. The first splicing block 101 and the second splicing block 102 are set to be detachable, which facilitates the removal of the receiving box 40 from the receiving area.

[0054] Ferromagnetic impurities are adsorbed on the periphery of the ferromagnetic rod. Long-term adsorption will cause the ferromagnetic impurities to cover the periphery of the ferromagnetic rod, thereby reducing the adsorption effect of the ferromagnetic rod. At this time, it is necessary to clean the ferromagnetic impurities on the periphery of the magnet rod 203, and set the first splicing arc 2011 and the second splicing arc 2012 to be detachable. This can expose the separation frame 202 and the magnet rod 203, making it easier to install and remove the magnet rod 203.

[0055] One end of the embedded block 2032 is set to an elliptical shape. Therefore, during the installation and removal process of the magnet rod 203, when the elliptical part of the embedded block 2032 is squeezed, the embedded block 2032 will be retracted into the storage cavity 2031; when the magnet rod 203 is installed, the staff holds the magnet rod 203 and inserts it into the through hole 2021, so that the separation frame 202 squeezes the embedded block 2032, and the embedded block 2032 is retracted into the storage cavity 2031 until the embedded block 2032 is completely received in the storage cavity 2031, and then The staff can rotate or move the magnet rod 203 back and forth in the through hole 2021 until the storage cavity 2031 and the embedding groove 2022 are aligned, and the elastic member 2033 releases the elastic force to insert the embedding block 2032 into the embedding groove 2022; when the magnet rod 203 is removed, the staff rotates the magnet rod 203 so that the separation frame 202 squeezes the embedding block 2032 until the embedding block 2032 is completely retracted into the storage cavity 2031, so that the staff can pull the magnet rod 203 out of the through hole 2021.

[0056] In some embodiments, see Figure 1 and Figure 4 A bulk material system is provided between the separation unit 20 and the discharge unit 30, and the bulk material system includes a reciprocating unit 50, a plurality of bulk material boxes 60 and a rotating unit 70; the reciprocating unit 50 includes two connecting frames 501 and a conveyor 502 fixed between the two connecting frames 501, the connecting frame 501 is U-shaped, the connecting frame 501 is rotatably connected to the separation cylinder 201, the connecting frame 501 rotates around the central axis of the separation cylinder 201, and a gap is left between the end of the conveyor 502 and the connecting frame 501; a plurality of bulk material boxes 60 are provided on the conveyor 502, and are distributed in sequence along the transmission direction of the conveyor 502. The bulk material box 60 is provided with an inlet 601 for receiving alloy powder and an outlet 602 for releasing alloy powder, and the bulk material box 60 can pass through the gap; the rotating unit 70 is connected to the connecting frame 501, and is used to drive the connecting frame 501 to rotate.

[0057] The rotating unit 70 includes a rotating frame 701, a driven ring gear 702 and a driving gear 703. The rotating frame 701 is annular. The bottom of one side of the rotating frame 701 is fixedly connected to the top of the first splicing arc 2011. The two connecting frames 501 are both arranged in the inner ring of the rotating frame 701. The two connecting frames 501 are rotatably connected to the inner wall of the rotating frame 701 on the opposite sides. The inner wall of the rotating frame 701 is annularly provided with an annular groove 7011. The driven ring gear 702 is arranged in the annular groove 7011. The two connecting frames 501 are both fixedly connected to the inner wall of the rotating frame 701. At least one driving gear 703 is provided. A third driving member 7012 corresponding to the driving gear 703 is installed in the annular groove 7011. The third driving member 7012 is transmission-connected to the driving gear 703.

[0058] It should be noted that the third driving component 7012 is a motor, and the output shaft of the motor is fixedly connected to the driving gear 703 .

[0059] The third driving member 7012 is started to drive the driving gear 703 to rotate, the driving gear 703 drives the driven ring gear 702 to rotate, and the driven ring gear 702 drives the two connecting frames 501 to rotate, so that the two connecting frames 501 drive the conveyor 502 to rotate, thereby changing the movement direction of the bulk material box 60, avoiding the accumulation of alloy powder, and allowing the alloy powder to fully contact with the magnet rod 203.

[0060] In some embodiments, see Figure 5 and Figure 7 A temporary storage chamber 603 connected to the inlet 601 is provided in the bulk box 60, and a feeding chamber 604 connecting the temporary storage chamber 603 with the outlet 602 is provided in the bulk box 60. A feeding roller 605 is rotatably connected in the feeding chamber 604, and the rotation axis of the feeding roller 605 is parallel to the movement direction of the bulk box 60. A first driving member 606 connected to the feeding roller 605 is installed on the bulk box 60, and a feeding blade 6051 is spirally fixed on the outer periphery of the feeding roller 605.

[0061] It should be noted that the first driving member 606 is a motor, and the output shaft of the first driving member 606 is fixedly connected to the feeding roller 605 .

[0062] The alloy powder enters the temporary storage chamber 603 through the inlet 601. When the conveyor 502 drives the bulk box 60 to move to the bottom of the conveyor 502, the first driving member 606 starts to drive the feed roller 605 to rotate. The feed roller 605 drives the feed blade 6051 to rotate, causing the alloy powder to move along the feed roller 605 to the outlet 602. The alloy powder then falls into the separation cylinder 201 through the outlet 602.

[0063] In some embodiments, see Figure 8 and Figure 9 A material guide plate 80, a telescopic member 608 located below the material guide plate 80 and connected to the bulk material box 60, and a push plate 607 connected to the telescopic member 608 are provided in the temporary storage chamber 603. The push plate 607 is also slidably connected to the bulk material box 60 along a first path. The first path is perpendicular to the movement path of the bulk material box 60. The telescopic member 608 is used to drive the push plate 607 to slide along the first path.

[0064] It should be noted that the telescopic member 608 can be a telescopic oil cylinder, an electric cylinder, or a hydraulic cylinder.

[0065] After the alloy powder falls into the temporary storage chamber 603 , the push plate 607 is driven by the telescopic member 608 to push the alloy powder toward the feeding blade 6051 , so that all the alloy powder in the temporary storage chamber 603 is sent out.

[0066] Specifically, the material guide plate 80 is tilted, and the fixed end of the material guide plate 80 is higher than the free end; when the entrance 601 is in the open state, the telescopic member 608 drives the push plate 607 to slide to the bottom of the material guide plate 80.

[0067] Another embodiment of the guide plate 80 is that a guide block 801 is provided on the top of the guide plate 80, and a guide groove 609 adapted to the guide block 801 is opened on the inner wall of the bulk material box 60 in the up and down directions, and the guide block 801 is slidably adapted in the guide groove 609, and the hinge axis of the guide plate 80 and the guide block 801 is parallel to the movement direction of the bulk material box 60; the bottom side of the guide plate 80 and the top side of the push plate 607 are hinged, and the hinge axis of the guide plate 80 and the push plate 607 are parallel to the movement direction of the bulk material box 60.

[0068] By providing the guide plate 80 , the alloy powder will not fall into the side of the push plate 607 facing the telescopic member 608 , thereby reducing the probability of hindering the normal movement of the push plate 607 .

[0069] In some embodiments, see Figure 5 and Figure 6 The inner wall of the bulk box 60 is provided with a through slot 610, and two through slots 610 are provided along the movement direction of the bulk box 60; a covering plate 611 is provided between the two opposite through slots 610, and an opening and closing rack 6111 is fixed on the surface of the covering plate 611 along its own length direction. The outer wall of the bulk box 60 is rotatably connected to an opening and closing gear 612 that meshes with the opening and closing rack 6111, and the rotation axis of the opening and closing gear 612 is perpendicular to the movement direction of the bulk box 60. The outer wall of the bulk box 60 is installed with a second driving member 613, which is transmission-connected to the opening and closing gear 612.

[0070] It should be noted that the second driving member 613 is a motor, and the motor is fixedly connected to the opening and closing gear 612 .

[0071] The first transmitter and the second transmitter are installed at the bottom of the storage barrel 301, and the top wall of the bulk material box 60 is installed with a receiver for receiving signals from the first transmitter and the second transmitter, and the receiver is in communication connection with the second driving member 613;

[0072] When the receiver receives the first transmitter signal, the second driving member 613 is activated, causing the cover plate 611 to slide to open the inlet 601, and the valve 3011 to open with a delay before the inlet 601 opens; when the receiver receives the second transmitter signal, the second driving member 613 is activated, causing the cover plate 611 to slide to close the inlet 601, and the valve 3011 to close with a delay before the inlet 601 closes.

[0073] The second driving member 613 is started to drive the opening and closing gear 612 to rotate, and the rotation of the opening and closing gear 612 drives the covering plate 611 to move through the opening and closing rack 6111, thereby opening and closing the entrance 601.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
