Description

Technical Field

[0001] This invention relates to the field of magnetic powder drying technology, specifically to a dehumidification and drying device and method for water-atomized high-purity soft magnetic powder. Background Technology

[0002] High-purity soft magnetic powder is a key raw material for high-end electronic magnetic components such as high-frequency transformers and precision inductors. The quality of powder drying directly affects the magnetic permeability, low-loss characteristics and stability of the finished product. The uniformity and cleanliness of powder drying are subject to strict requirements. At present, in industrial production, the dehumidification and drying process of high-purity soft magnetic powder is mostly completed by double cone rotary drying equipment.

[0003] Existing double-cone rotary dryers have significant limitations in practical production applications. The drying chamber volume and rotational force structure of such equipment are fixed designs, which impose extremely strict limitations on the weight of materials processed in a single batch. Due to slight fluctuations in the bulk density of high-purity soft magnetic powder between batches, a pre-weighing process must be added during production to accurately measure and proportion the powder in order to match the rated load weight of the equipment and ensure the drying effect. If the material weight deviation exceeds the standard, it will lead to uneven heating and airflow of the powder in the chamber, resulting in problems such as incomplete drying in some areas and uneven moisture content, which seriously affects the quality of the powder. At the same time, the redundant weighing process significantly increases the production process, reduces operating efficiency, and increases labor and equipment costs. Summary of the Invention

Spring rods are fixedly connected to both ends of the outer wall of the stop block, and the ends of the two spring rods are fixedly connected to the inner wall of the control box, while the end of the outer wall of the stop block away from the spring rod is in contact with the bottom of the discharge funnel.

[0017] A method for dehumidifying and drying high-purity soft magnetic powder using water atomization, the method employing the aforementioned dehumidifying and drying device for high-purity soft magnetic powder using water atomization, as follows:

[0018] S1: Based on the existing drying body, it consists of two hollow main shafts, a frame base, a transmission assembly, a constant temperature heating assembly, a vacuum assembly, and a cooling circulation assembly. The double cone drying tank is installed between the two hollow main shafts. By setting a feeding block at the top of the double cone drying tank, a feeding funnel is embedded in the slot at the top of the linkage cavity on its inner wall. The linkage cavity is equipped with a distribution bin with a feeding chamber and a moving bin. The powder falls into the distribution bin through the feeding funnel and enters the moving bin along the inclined surface of the feeding chamber. As the powder accumulates, the moving bin moves downward under gravity, driving the bottom first tooth plate, linkage gear rod, linkage gear, and transmission gear rod to rotate, driving the discharge funnel to rotate counterclockwise by 130 degrees. At this time, the moving bin blocks the opening of the feeding chamber, and the powder falls into the discharge funnel along the inclined surface at the bottom of the moving bin.

[0019] S2: The linkage chamber and partition are equipped with a control box with a fixing ring, a stop block and a spring rod. The stop block supports the discharge funnel. The maximum load of the spring rod is 950 to 980 grams. When the powder in the discharge funnel exceeds 980 grams, the stop block is squeezed into the control box. The discharge funnel rotates 130 degrees clockwise to complete the discharge. At the same time, the first toothed plate drives the moving chamber to reset. The moving chamber can only be triggered to move down when the total weight exceeds 2 kilograms. After the feeding is completed, the electric control valve can be closed and the various components of the drying body can be started to perform vacuum and dehumidification drying on the powder in the double cone drying tank. After drying, the powder is discharged through the bottom discharge pipe.

[0020] S3: The linkage disc at the end of the transmission gear rod is equipped with a push rod and an arc-shaped protrusion, which can drive the driven grooved wheel rod, the push disc and the double gear with a counting disc to rotate. The counting disc, together with the observation slot, can record the total amount of feed. It can be adapted to a double cone drying tank with a maximum volume of 18 kg. At the same time, the double gear rod can drive the second tooth plate, connecting rod, turntable and guide gear rod to rotate. By adjusting the position of the control plate in the fixed box, the movement range of the chain rack can be limited, and the quantitative discharge of powder can be precisely controlled to achieve quantitative feeding of a specified weight.

[0021] S4: After the equipment stops, the baffle installed on the inner wall of the discharge chamber can be pulled to clean the residual powder in the feed tray, feed chamber and moving bin. The residual powder is discharged through the feed pipe by rotating the handle to drive the spiral blade. After feeding is completed, the second limit box can be moved by pulling the extension plate to reset the chain rack. The reset structure of the chain rack is fixed by pressing down the control plate to ensure stable operation of the equipment.

[0022] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0023] This invention provides a dehumidification and drying device and method for water-atomized high-purity soft magnetic powder. By setting an elastic frame on the side of the inner wall of the second fixed frame away from the pusher plate, and setting a rotating plate at the end of the elastic frame, the rotating plate and the elastic frame dampen and limit the driven grooved wheel rod, preventing small-amplitude offset rotation of the driven grooved wheel rod during the movement of the second fixed frame. Since a transmission gear is set at one end of the outer wall of the driven grooved wheel rod, and a double gear is set on the outer wall of the transmission gear, and a counting disk is set on one side of the outer wall of the double gear, this invention further solves the existing defects of traditional water-atomized high-purity soft magnetic powder dehumidification and drying devices: traditional equipment requires an additional weighing step in the drying process to ensure drying effect, which both increases the drying process and reduces the overall processing efficiency of water-atomized high-purity soft magnetic powder.

A linkage disc 21 is fixedly connected to the end of the outer wall of the transmission gear rod 17 away from the discharge funnel 19.

The two ends of the outer wall of the driven grooved wheel rod 26 are rotatably connected to a second fixed frame 27, and the top of the second fixed frame 27 is fixedly connected to an elastic telescopic platform 28. The top of the elastic telescopic platform 28 is fixedly connected to the inner wall of the linkage cavity 5. One end of the outer wall of the driven grooved wheel rod 26 is fixedly connected to a transmission gear 29, and a double gear 30 meshes with the outer wall of the transmission gear 29.

An observation groove 31 is provided on one side of the outer wall of the feed block 4, and a counting disk 32 is slidably connected to the inner wall of the observation groove 31. The outer wall of the counting disk 32 is fixedly connected to the outer wall of the double gear 30. An elastic frame 33 is fixedly connected to the inner wall of the second fixed frame 27 on the side away from the pusher disk 25, and a rotating plate 34 is rotatably connected to the end of the elastic frame 33. One side of the outer wall of the rotating plate 34 contacts the outer wall of the driven grooved wheel rod 26.

[0037] During operation, two hollow spindles are installed in the drying body 1 (which consists of two hollow spindles, a frame base, a transmission assembly, a constant temperature heating assembly, a vacuum assembly, and a cooling circulation assembly; the transmission assembly consists of a variable frequency motor and a reducer; the constant temperature heating assembly consists of a circulating pump, an expansion tank, and a thermometer; the vacuum assembly consists of a vacuum pump and a buffer tank; and the cooling circulation assembly consists of a water-cooled condenser and a recovery tank, which is existing technology). The double-cone drying tank 2 is installed between the two hollow spindles. A feed block 4 is installed at the top of the double-cone drying tank 2, and a linkage cavity 5 is set on the inner wall of the feed block 4. A slot 6 is set at the center of the top of the inner wall of the linkage cavity 5, and the bottom of the feed tray 7 is embedded in the slot 6. Because a material distribution chamber 9 is provided at one end of the inner wall of the linkage cavity 5 near the slot 6, and a feeding chamber 10 is provided at the top of the inner wall of the material distribution chamber 9, and a movable chamber 12 is provided on one side of the outer wall of the material distribution chamber 9, when the water-atomized high-purity soft magnetic powder is poured into the feeding tray 7 and enters the material distribution chamber 9, the water-atomized high-purity soft magnetic powder enters the movable chamber 12 along the inclined surface of the bottom of the feeding chamber 10. As more and more water-atomized high-purity soft magnetic powder enters the movable chamber 12, the movable chamber 12 gradually moves downward under the influence of gravity. By providing a first toothed plate 13 at the center of the bottom of the movable chamber 12, the first toothed plate 13 moves downward synchronously during the downward movement of the movable chamber 12. Because a first fixed frame is provided on the inner wall of the linkage cavity 5... 14. Thus, the first fixed frame 14 constrains the downward-moving first toothed plate 13. By setting a linkage gear rod 15 (each gear rod in the text is composed of a gear and a rotating rod, which belongs to the prior art) on the inner wall of the linkage cavity 5, the first toothed plate 13 drives the linkage gear rod 15 to rotate. By setting a linkage gear 16 at the end of the linkage gear rod 15, the linkage gear 16 drives the transmission gear rod 17 set on one side of its outer wall to rotate. Since the inner wall of the linkage cavity 5 is provided with a partition 18, the partition 18 supports the transmission gear rod 17. By setting a discharge funnel 19 at one end of the outer wall of the transmission gear rod 17, the discharge funnel 19 rotates around the transmission gear rod 17 as the center, and moves in the opposite direction. As the clock rotates, the water-atomized high-purity soft magnetic powder in the feeding chamber 10 continuously enters the moving chamber 12, causing the moving chamber 12 to move downwards along the inner wall of the linkage chamber 5. A tray 20 is installed on the inner wall of the linkage chamber 5. Once the moving chamber 12 contacts the top of the tray 20, the discharge funnel 19 rotates counterclockwise by 130 degrees and remains horizontal. At this point, the top of the moving chamber 12 seals the opening of the feeding chamber 10, while the bottom of the moving chamber 12 is no longer blocked by the distribution chamber 9. Since the bottom of the inner wall of the moving chamber 12 is also inclined, the water-atomized high-purity soft magnetic powder in the moving chamber 12 flows along the inclined surface into the discharge funnel 19. A control box 50 is installed on the inner wall of the linkage chamber 5 and the inner wall of the partition 18.A fixing ring 51 is set at the center of the inner wall of the two control boxes 50, and a stop block 52 is set on the inner wall of the fixing ring 51. Since the outer wall of the stop block 52 is in contact with the bottom of the discharge funnel 19, and a spring rod 53 is set at the end of the outer wall of the stop block 52 away from the discharge funnel 19, the stop block 52, which is limited by the spring rod 53, supports the discharge funnel 19. After the water atomized high-purity soft magnetic powder in the moving chamber 12 has completely entered the discharge funnel 19, the total weight of the discharge funnel 19 is greater than the elastic force of the spring rod 53. Under the pressure of the discharge funnel 19, the stop block 52 is squeezed into the control box 50. At the same time, the discharge funnel 19 loses the support of the stop block 52 and rotates 130 degrees clockwise. During this period, the discharge funnel 19 drives the linkage gear 16 and the linkage gear 15 through the transmission gear rod 17. The mechanism rotates stepwise, causing the linkage gear rod 15 to push the moving chamber 12 away from the top of the tray 20 via the first toothed plate 13, and then reset. This allows the water-atomized high-purity soft magnetic powder in the feeding chamber 10 to re-enter the moving chamber 12. An electrically controlled valve 8 is installed at the bottom of the feeding block 4. After the water-atomized high-purity soft magnetic powder is fed in, the valve 8 is closed. At this time, the vacuum assembly is activated to first perform vacuum drying on the water-atomized high-purity soft magnetic powder in the double-cone drying tank 2. Simultaneously, the transmission assembly, constant temperature heating assembly, and cooling circulation assembly are activated to dehumidify and dry the water-atomized high-purity soft magnetic powder in the double-cone drying tank 2. After the water-atomized high-purity soft magnetic powder is processed, the discharge pipe 3 is installed at the bottom of the double-cone drying tank 2, and the cap at the bottom of the discharge pipe 3 is removed to discharge the water-atomized high-purity soft magnetic powder.

[0038] It should be further explained that the maximum normal operating volume of the double-cone drying tank 2 is 18 kg, and the maximum load-bearing capacity of the spring rod 53 is between 950 g and 980 g (this load-bearing capacity does not include the weight of the discharge funnel 19 itself; the stop block 52 can only retract into the control box 50 when the weight of the water-atomized high-purity soft magnetic powder in the discharge funnel 19 exceeds 950 g to 980 g). Therefore, when the water-atomized high-purity soft magnetic powder in the moving chamber 12 enters the discharge funnel 19 along its inclined surface, once the weight of the water-atomized high-purity soft magnetic powder in the discharge funnel 19 exceeds 980 g, the stop block 52 can no longer support the discharge funnel 19 and cause the discharge funnel 19 to rotate. Because the discharge funnel 19 is provided with grooves, when the discharge funnel 19 rotates clockwise... After rotating 130 degrees, all the water-atomized high-purity soft magnetic powder in the discharge funnel 19 can be discharged. At the same time, during the rotation of the discharge funnel 19, the first toothed plate 13 is pushed by the linkage gear rod 15 to reset the moving chamber 12. Since a one-way damping spring is provided between the first toothed plate 13 and the first fixed frame 14, the moving chamber 12 can only move downward when the total weight of the moving chamber 12 and the water-atomized high-purity soft magnetic powder inside exceeds two kilograms. At this time, the force generated by the downward pressure of the moving chamber 12 far exceeds the maximum force that the spring rod 53 can bear, so that the discharge funnel 19, which has been rotated 130 degrees counterclockwise to reset, pushes the stop block 52 back into the control box 50. After the discharge funnel 19 is reset, the rebounding stop block 52 supports the bottom of the discharge funnel 19.

[0039] It needs to be explained again that by setting a linkage disc 21 at the end of the outer wall of the transmission gear rod 17 away from the discharge funnel 19, and setting a push rod 22 on one side of the outer wall of the linkage disc 21, since the inner wall of the linkage cavity 5 is provided with an elastic telescopic platform 28, and the output end of the elastic telescopic platform 28 is provided with a second fixed frame 27, and the inner wall of the second fixed frame 27 is provided with a driven grooved wheel rod 26, by setting a push disc 25 at one end of the outer wall of the driven grooved wheel rod 26, when the discharge funnel 19 rotates 130 degrees clockwise, the transmission gear rod 17 drives the linkage disc 21 to rotate 130 degrees, and the push rod 22 pushes the driven grooved wheel rod 26 to rotate 60 degrees. An arc-shaped protrusion 24 is provided at one end of the wall. When the push rod 22 drives the driven grooved wheel rod 26 to rotate 60 degrees and disengages from the driven grooved wheel rod 26, the arc-shaped protrusion 24 presses against the push plate 25, simultaneously causing the second fixed frame 27 and the driven grooved wheel rod 26 to move upwards as a whole. An elastic frame 33 is provided on the inner wall of the second fixed frame 27 away from the push plate 25, and a rotating piece 34 is provided at the end of the elastic frame 33. The rotating piece 34 and the elastic frame 33 dampen and limit the driven grooved wheel rod 26, preventing a small-amplitude offset rotation of the driven grooved wheel rod 26 during the movement of the second fixed frame 27. Because one end of the outer wall of the driven grooved wheel rod 26 is provided with… A transmission gear 29 is provided, and a double gear 30 is provided on the outer wall of the transmission gear 29. A counting disk 32 is provided on one side of the outer wall of the double gear 30 (the counting disk 32 is composed of a ratchet and a digital disk, which is the prior art. The numbers on the surface of the digital disk are one to six, and the digital disk can rotate three times. Each number represents one kilogram, and the maximum capacity of the double cone drying tank 2 is eighteen kilograms). An observation groove 31 is provided on one side of the outer wall of the feed block 4, and one end of the inner wall of the observation groove 31 is provided with glass. So when the second fixed frame 27 moves upward, it synchronously drives the counting disk 32 to move upward along the observation groove 31, and causes the numbers on the surface of the counting disk 32 to rotate one kilogram. When the discharge funnel 19 is reset, the arc-shaped protrusion 24 disengages from the support of the push plate 25, and under the elastic action of the elastic telescopic table 28, the second fixed frame 27 is reset. At the same time, when the linkage plate 21 drives the push rod 22 to rotate counterclockwise, it cannot contact the driven groove wheel rod 26, thereby achieving the purpose of recording the total amount of water atomized high-purity soft magnetic powder entering the double cone drying tank 2. This further solves the existing defects of the traditional water atomized high-purity soft magnetic powder dehumidification and drying device: in order to ensure the drying effect, the traditional equipment needs to add a weighing step in the drying process, which not only adds an extra drying process but also reduces the overall processing efficiency of water atomized high-purity soft magnetic powder.

[0040] The bottom of the double gear rod 23 meshes with a second gear plate 35, and the bottom of the second gear plate 35 is slidably connected to a first limiting box 36. The bottom of the first limiting box 36 is fixedly connected to the inner wall of the linkage cavity 5. One end of the outer wall of the second gear plate 35 is rotatably connected to a connecting rod 37, and the end of the connecting rod 37 is rotatably connected to a turntable 38. One side of the outer wall of the turntable 38 is fixedly connected to a guide gear rod 39, one side of the outer wall of the guide gear rod 39 is rotatably connected to the outer wall of the partition plate 18, and one side of the outer wall of the guide gear rod 39 meshes with a chain rack 40. The outer wall of the chain rack 40 is slidably connected to a second limiting box 41, the bottom of the second limiting box 41 is slidably connected to a third limiting box 42, and the bottom of the third limiting box 42 is fixedly connected to the bottom of the linkage cavity 5. One side of the outer wall of the second limiting box 41 is fixedly connected to an extension plate 43, and the extension plate 43 is... One end of the wall is slidably connected to the outer wall of the feed block 4. The inner wall of the second limiting box 41 is slidably connected to the control plate 44 at the end away from the chain rack 40. The center of the outer wall of the control plate 44 is slidably connected to the fixing box 45. One end of the outer wall of the fixing box 45 is fixedly connected to the inner wall of the linkage cavity 5. One end of the outer wall of the control plate 44 is slidably connected to the outer wall of the feed block 4. One end of the inner wall of the discharge cavity 11 is slidably connected to the baffle 46. The outer wall of the baffle 46 penetrates and is slidably connected to the inner wall of the feed block 4. The inner wall of the discharge cavity 11 is connected to the feeding pipe 47 through and fixedly connected to the end away from the baffle 46. One end of the inner wall of the feeding pipe 47 is connected to the handle 48 through and rotatably connected to the handle 48. The bottom end of the feeding pipe 47 is provided with a discharge port. The end of the handle 48 is fixedly connected to the spiral blade 49. The end of the spiral blade 49 is rotatably connected to the inner wall of the discharge cavity 11.

[0041] During operation, a double gear rod 23 is installed at the end of the outer wall of the linkage disk 21 away from the transmission gear rod 17, and a second toothed plate 35 is installed at the bottom of the double gear rod 23. When the transmission gear rod 17 reciprocates, the double gear rod 23 synchronously drives the second toothed plate 35 to reciprocate within the first limiting box 36 installed on the inner wall of the linkage cavity 5. A connecting rod 37 is installed at one end of the outer wall of the second toothed plate 35, and a turntable 38 is installed at the end of the connecting rod 37. This causes the reciprocating second toothed plate 35 to drive the turntable 38 to rotate counterclockwise via the connecting rod 37. Since a guide gear rod 39 is installed on one side of the outer wall of the turntable 38, and one side of the outer wall of the guide gear rod 39 is supported by the outer wall of the partition plate 18, a third limiting box 42 is installed at the bottom of the linkage cavity 5, and a second limiting box 41 is installed on the inner wall of the third limiting box 42. A chain rack 40 is installed on the inner wall of the second limiting box 41. At the same time, one side of the outer wall of the guide gear rod 39 is connected to the chain rack 40. The teeth of the rack 40 mesh, while the bottom of the guide gear rod 39 does not contact the chain rack 40. When it is necessary to add water-atomized high-purity soft magnetic powder in a quantitative manner, a fixed box 45 is set on the inner wall of the linkage cavity 5, and a control plate 44 is set on the inner wall of the fixed box 45. One end of the control plate 44 extends out of the feed block 4, while the other end is in the second limit box 41. By adjusting the position of the control plate 44 in the fixed box 45, the movement range of the chain rack 40 in the second limit box 41 is shortened. When it is necessary to add 12 kg of water-atomized high-purity soft magnetic powder to the double cone drying tank 2, the control plate 44 is moved to a suitable position. After the discharge funnel 19 discharges normally, the guide gear rod 39 continues to drive the chain rack 40 to move in the second limit box 41. When the top of the chain rack 40 contacts the bottom of the control plate 44, the guide gear rod 39 and other structures cannot operate, thereby achieving the purpose of accurately controlling the discharge amount of water-atomized high-purity soft magnetic powder.

[0042] It should be further explained that, since water-atomized high-purity soft magnetic powder is still present in the feed tray 7, feed chamber 10 and moving chamber 12 at this time, a discharge chamber 11 is set at one end of the inner wall of the distribution chamber 9 near the feed chamber 10, and a baffle 46 is set at one end of the inner wall of the discharge chamber 11. After the discharge funnel 19 stops working, the baffle 46 is pulled to allow the water-atomized high-purity soft magnetic powder remaining in the feed tray 7, feed chamber 10 and moving chamber 12 to enter the discharge chamber 11. A feeding pipe 47 is set at one end of the inner wall of the feed chamber 10 away from the baffle 46, and a handle 48 is set at one end of the inner wall of the feeding pipe 47. A spiral blade 49 is set at the end of the handle 48. By rotating the handle 48, the spiral blade 49 discharges the water-atomized high-purity soft magnetic powder in the discharge chamber 11 into the feeding pipe 47, and discharges it through the discharge port set at one end of the bottom of the feeding pipe 47.

[0043] It should be reiterated that after a measured amount of water-atomized high-purity soft magnetic powder is fed into the double-cone drying tank 2, an extension plate 43 is provided on one side of the outer wall of the second limiting box 41. Pulling the extension plate 43 causes the second limiting box 41 to move within the third limiting box 42, and the end of the control plate 44 disengages from the second limiting box 41. At this time, the chain rack 40 loses the support of the guide gear rod 39 and resets under the action of gravity. Then, the extension plate 43 is pushed to reset the second limiting box 41. To avoid gaps between the chain rack 40 and the guide gear rod 39, the control plate 44 is pressed down to the bottom to fix the chain rack 40 at its bottom. Then, the extension plate 43 is pushed until the chain rack 40 and the guide gear rod 39 mesh with each other.

[0044] A method for dehumidifying and drying high-purity soft magnetic powder using water atomization, the method employing the aforementioned dehumidifying and drying device for high-purity soft magnetic powder using water atomization, as follows:

[0045] S1: Based on the existing drying body 1, which consists of two hollow main shafts, a frame base, a transmission assembly, a constant temperature heating assembly, a vacuum assembly, and a cooling circulation assembly, the double cone drying tank 2 is installed between the two hollow main shafts. By setting a feeding block 4 at the top of the double cone drying tank 2, a feeding tray 7 is embedded in the top slot 6 of the linkage cavity 5 on its inner wall. The linkage cavity 5 is equipped with a distribution bin 9 with a feeding chamber 10 and a moving bin 12. The powder falls into the distribution bin 9 through the feeding tray 7 and enters the moving bin 12 along the inclined surface of the feeding chamber 10. As the powder accumulates, the moving bin 12 moves downward under gravity, driving the bottom first tooth plate 13, the linkage gear rod 15, the linkage gear 16, and the transmission gear rod 17 to rotate, driving the discharge funnel 19 to rotate counterclockwise by 130 degrees. At this time, the moving bin 12 blocks the opening of the feeding chamber 10, and the powder falls into the discharge funnel 19 along the inclined surface of the bottom of the moving bin 12.

[0046] S2: The linkage cavity 5 and the partition plate 18 are equipped with a control box 50 with a fixing ring 51, a stop block 52 and a spring rod 53. The stop block 52 supports the discharge funnel 19. The maximum load capacity of the spring rod 53 is 950 to 980 grams. When the powder in the discharge funnel 19 exceeds 980 grams, the stop block 52 is squeezed into the control box 50. The discharge funnel 19 rotates 130 degrees clockwise to complete the discharge. At the same time, the first toothed plate 13 drives the moving chamber 12 to reset. The one-way damping spring between the first toothed plate 13 and the first fixed frame 14 requires a total weight of more than 2 kg to trigger the moving chamber 12 to move down, ensuring the stability of the circulating feeding and discharging. After feeding is completed, the electric control valve 8 can be closed, and the components of the drying body 1 can be started to perform vacuum and dehumidification drying on the powder in the double cone drying tank 2. After drying, the powder is discharged through the bottom discharge pipe 3.

[0047] S3: The linkage disk 21 at the end of the transmission gear rod 17 is equipped with a push rod 22 and an arc-shaped protrusion 24, which can drive the driven grooved wheel rod 26, the push disk 25 and the double gear 30 with a counting disk 32 to rotate. The counting disk 32, together with the observation slot 31, can record the total amount of feed. It can be adapted to the double cone drying tank 2 with a maximum volume of 18 kg. At the same time, the double gear rod 23 can drive the second tooth plate 35, the connecting rod 37, the turntable 38 and the guide gear rod 39 to rotate. By adjusting the position of the control plate 44 in the fixed box 45, the movement range of the chain rack 40 can be limited, and the quantitative discharge of powder can be precisely controlled to achieve a quantitative feed of 12 kg or other specified weights.

[0048] S4: After the equipment stops, the baffle 46 on the inner wall of the discharge chamber 11 can be pulled to clean the residual powder in the feed tray 7, feed chamber 10 and moving chamber 12. The spiral blades 49 are driven by rotating the handle 48 to discharge the residual powder through the feed pipe 47. After feeding is completed, the second limit box 41 can be moved by pulling the extension plate 43 to reset the chain rack 40. The reset structure of the chain rack 40 is fixed by pressing down the control plate 44 to eliminate the gear and rack meshing gap and ensure the stable operation of the equipment in the future.

[0049] The working principle of the dehumidification and drying device and method for water atomization of high-purity soft magnetic powder is explained in detail below.

[0050] like Figures 1 to 10As shown, by setting two hollow main shafts in the drying body 1, the double-cone drying tank 2 is installed between the two hollow main shafts. A feeding block 4 is set at the top of the double-cone drying tank 2, and a linkage cavity 5 is set on the inner wall of the feeding block 4. A slot 6 is set at the center of the top of the inner wall of the linkage cavity 5, and the bottom of the feeding tray 7 is embedded in the slot 6. Since a distribution chamber 9 is set at one end of the inner wall of the linkage cavity 5 near the slot 6, and a feeding cavity 10 is set at the top of the inner wall of the distribution chamber 9, and a moving chamber 12 is set on one side of the outer wall of the distribution chamber 9, when the water-atomized high-purity soft magnetic powder is poured into the feeding tray 7 and enters the distribution chamber 9, the water-atomized high-purity soft magnetic powder enters the moving chamber 12 along the inclined surface of the bottom of the feeding cavity 10. As more and more water-atomized high-purity soft magnetic powder enters the moving chamber 12, the moving chamber 12 gradually moves downward under the influence of gravity. A first toothed plate 13 is positioned at the center of the bottom of the moving chamber 12, causing the first toothed plate 13 to move downward synchronously during the downward movement of the moving chamber 12. Since a first fixing frame 14 is provided on the inner wall of the linkage cavity 5, the first fixing frame 14 constrains the downward-moving first toothed plate 13. A linkage gear rod 15 is provided on the inner wall of the linkage cavity 5, causing the first toothed plate 13 to drive the linkage gear rod 15 to rotate. A linkage gear 16 is provided at the end of the linkage gear rod 15, thereby driving the transmission gear rod 17 provided on one side of its outer wall to rotate. Since a partition 1 is provided on the inner wall of the linkage cavity 5... 8. Thus, the partition 18 supports the transmission gear rod 17. A discharge funnel 19 is set at one end of the outer wall of the transmission gear rod 17. As the transmission gear rod 17 rotates, the discharge funnel 19 rotates counterclockwise around the transmission gear rod 17. At this time, the water-atomized high-purity soft magnetic powder in the feeding chamber 10 continuously enters the moving chamber 12, and continuously moves the moving chamber 12 downward on the inner wall of the linkage chamber 5. The inner wall of the linkage chamber 5 is provided with a tray 20. When the continuously moving moving chamber 12 contacts the top of the tray 20, the discharge funnel 19 rotates 130 degrees counterclockwise. At this time, the top of the moving chamber 12 seals the opening of the feeding chamber 10, and the bottom of the moving chamber 12 is no longer sealed by the distribution chamber 9. The bottom of the inner wall of the movable chamber 12 is also inclined, allowing the water-atomized high-purity soft magnetic powder in the movable chamber 12 to enter the discharge funnel 19 along the inclined surface. A linkage disc 21 is installed on the outer wall of the transmission gear rod 17 away from the discharge funnel 19, and a push rod 22 is installed on one side of the outer wall of the linkage disc 21. Since the inner wall of the linkage cavity 5 is provided with an elastic telescopic platform 28, and the output end of the elastic telescopic platform 28 is provided with a second fixed frame 27, and the inner wall of the second fixed frame 27 is provided with a driven grooved wheel rod 26, a push disc 25 is installed on one end of the outer wall of the driven grooved wheel rod 26. When the discharge funnel 19 rotates 130 degrees clockwise, the transmission gear rod 17 drives the linkage disc 21 to rotate 130 degrees, and the push rod 22 pushes the driven grooved wheel rod 26 to rotate 60 degrees.Because one end of the outer wall of the linkage disk 21 is provided with an arc-shaped protrusion 24, when the push rod 22 drives the driven grooved wheel rod 26 to rotate 60 degrees and causes the push rod 22 to disengage from the driven grooved wheel rod 26, the arc-shaped protrusion 24 presses against the push disk 25, and simultaneously drives the second fixed frame 27 and the driven grooved wheel rod 26 to move upward as a whole. By providing an elastic frame 33 on the inner wall of the second fixed frame 27 away from the push disk 25, and providing a rotating piece 34 at the end of the elastic frame 33, the rotating piece 34 and the elastic frame 33 provide damping and limiting for the driven grooved wheel rod 26, preventing the second fixed frame 27 from moving during the process. This causes a slight offset rotation of the driven grooved wheel rod 26. Since a transmission gear 29 is provided at one end of the outer wall of the driven grooved wheel rod 26, and a double gear 30 is provided on the outer wall of the transmission gear 29, and a counting disk 32 is provided on one side of the outer wall of the double gear 30, and an observation groove 31 is provided on one side of the outer wall of the feed block 4, with glass at one end of the inner wall of the observation groove 31, when the second fixed frame 27 moves upward, it synchronously drives the counting disk 32 to move upward along the observation groove 31, causing the number on the surface of the counting disk 32 to rotate by one position. When the discharge funnel 19 resets, the arc-shaped protrusion... 24. The support of the pusher plate 25 is released, and under the elastic action of the elastic telescopic table 28, the second fixed frame 27 is reset. At the same time, when the linkage plate 21 drives the push rod 22 to rotate counterclockwise, it cannot contact the driven groove wheel rod 26, thereby achieving the purpose of recording the total amount of water-atomized high-purity soft magnetic powder entering the double cone drying tank 2. By setting an electric control valve 8 at the bottom of the feed block 4, after the water-atomized high-purity soft magnetic powder is fed, the electric control valve 8 is closed. At this time, the vacuum component is started to first process the water-atomized high-purity soft magnetic powder in the double cone drying tank 2. Vacuum drying is performed simultaneously with the activation of the transmission assembly, constant temperature heating assembly, and cooling circulation assembly to dehumidify and dry the water-atomized high-purity soft magnetic powder in the double-cone drying tank 2. After the water-atomized high-purity soft magnetic powder is processed, the cap at the bottom of the discharge pipe 3 is removed to discharge the water-atomized high-purity soft magnetic powder. This further solves the existing defects of traditional water-atomized high-purity soft magnetic powder dehumidification and drying devices: traditional equipment requires an additional weighing step in the drying process to ensure the drying effect, which not only adds extra steps to the drying process but also reduces the overall processing efficiency of water-atomized high-purity soft magnetic powder.

[0051] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.

At this time, the moving bin (12) blocks the opening of the feeding chamber (10), and the powder falls into the discharge funnel (19) along the inclined surface of the bottom of the moving bin (12). S2: The linkage cavity (5) and the partition plate (18) are equipped with a control box (50) with a fixing ring (51), a stop (52) and a spring rod (53). The stop (52) supports the discharge funnel (19). The maximum load of the spring rod (53) is 950 to 980 grams. When the powder in the discharge funnel (19) exceeds 980 grams, the stop (52) is squeezed into the control box (50). The discharge funnel (19) rotates 130 degrees clockwise to complete the discharge. At the same time, the first toothed plate (13) drives the moving chamber (12) to reset. The total weight must exceed 2 kilograms to trigger the moving chamber (12) to move down. After the feeding is completed, the electric control valve (8) can be closed, and the components of the drying body (1) are started to perform vacuum and dehumidification drying on the powder in the double cone drying tank (2). After drying, the powder is discharged through the bottom discharge pipe (3). S3: The linkage disk (21) at the end of the transmission gear rod (17) is equipped with a push rod (22) and an arc-shaped protrusion (24), which can drive the driven grooved wheel rod (26), the push disk (25) and the double gear (30) with the counting disk (32) to rotate. The counting disk (32) and the observation slot (31) can record the total amount of feed. It can be adapted to the maximum volume of the double cone drying tank (2) of 18 kg. At the same time, the double gear rod (23) can drive the second tooth plate (35), the connecting rod (37), the turntable (38) and the guide gear rod (39) to rotate. By adjusting the position of the control plate (44) in the fixed box (45), the movement range of the chain rack (40) can be limited, and the quantitative discharge of powder can be precisely controlled to achieve the quantitative feeding of the specified weight. S4: After the equipment stops, the baffle (46) set on the inner wall of the discharge chamber (11) can be pulled to clean the residual powder in the feed tray (7), feed chamber (10) and moving chamber (12). The spiral blade (49) is driven by rotating the handle (48) to discharge the residual powder through the feed pipe (47). After feeding is completed, the second limit box (41) can be moved by pulling the extension plate (43) to reset the chain rack (40). The control plate (44) is pressed down to fix the chain rack (40) and reset the structure, so that the equipment can run stably in the future.
