Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a dehydration dryer for iron powder cores. Background Technology

[0002] Iron powder core is a common name for the magnetic material magnetite (Fe3O4), primarily used in electrical circuits to address electromagnetic compatibility (EMC) issues. In practical applications, various other substances are added depending on the filtering requirements for different wavelengths. Iron powder cores often require dehydration and drying during the manufacturing process.

[0003] To address the problem of low efficiency in existing dehydration and drying processes, patent CN209341717U discloses a dehydration and drying device based on an iron powder core. The device includes a main body and a base. The main body contains a chamber divided into an upper chamber and a lower chamber by a partition plate. The top of the main body has a feed inlet communicating with the upper chamber. Multiple heating devices are fixed within the upper chamber, and the inner wall of the upper chamber has multiple protrusions of the same height. A plate is placed on each protrusion. The body has multiple circular holes, each containing a storage pouch. A weight is fixed to the bottom of each storage pouch, and the weight has multiple connecting channels that communicate with the upper chamber. These connecting channels are filled with absorbent material. A mounting groove is located at the center of the top of the base, where a motor is mounted. The motor shaft is connected to a shaft via a coupling, with the shaft pointing vertically upwards. The top of the motor shaft passes through the lower chamber and partition plate, inserting into the upper chamber. Multiple fan blades are welded to the side of the top of the shaft, and these blades contact the weight. While this solves the existing technical problems, the following issues remain:

[0004] In this technical solution, the storage bag shakes when it is patted, and the iron powder core inside also shakes. Therefore, the water is only shaken out by shaking, and its dehydration efficiency needs to be improved. Summary of the Invention

[0005] Based on the technical problems existing in the prior art, the present invention proposes a dehydration and drying machine for iron powder cores.

[0006] This invention proposes a dehydration and drying machine for iron powder cores, comprising a housing with baffles on both inner walls of the housing. A common carrier plate is placed between two baffles, and a circular hole is formed on the carrier plate. A storage bag for holding iron powder cores is placed inside the circular hole. The storage bag includes a support ring and a rubber bladder fixed to the bottom of the support ring. The support ring rests on the edge of the circular hole. The bottom of the rubber bladder has an integrally formed spherical protrusion, and the rubber bladder has a bent portion with densely distributed small holes. A [missing information - likely a component or element] is fixed inside the housing. A partition located below the baffle plate forms a drying chamber together with the carrier plate. A motor is installed below the partition plate, and the output shaft of the motor is connected to a main shaft passing through the partition plate. A fan blade that can contact the spherical protrusion is fixed at the top of the main shaft. The output shaft of the motor drives the main shaft and the fan blade to rotate. The fan blade strikes the spherical protrusion, causing the storage bag to be thrown to one side. The storage bag will bend and deform to one side at the bending part. The bending part is close to the iron powder core and squeezes it to squeeze out the moisture.

[0007] Preferably, a pair of hanging rods fixed to the bottom of the carrier plate are provided near the circular hole, and the bottom ends of the two hanging rods are fixed with the same arc-shaped stop bar.

[0008] Preferably, the stop bar is magnetic.

[0009] Preferably, the ring has multiple insertion holes arranged in a ring array, and multiple limiting posts arranged in a ring array and fixed to the top of the carrier plate are provided near the holes. Each limiting post is fitted with a collar that abuts against the bottom surface of the ring, and a spring is fixed to the bottom surface of the collar, which is fitted on the limiting post and has its bottom end abutting against the carrier plate.

[0010] Preferably, the storage bladder contains a pressure plate for pressing the iron powder core, and the pressure plate is provided with a dense array of water-permeable holes.

[0011] Preferably, the bottom inner wall of the housing is provided with a positioning protrusion ring, the motor is fixed inside the positioning protrusion ring, and a rubber ring is fitted on the motor, the outer surface of which abuts against the inner wall of the positioning protrusion ring.

[0012] Preferably, hot air blowers are fixed to the inner walls on both sides of the box and located inside the drying chamber, and the top of the box is covered with a cover plate with an observation window.

[0013] Preferably, the partition has a drain outlet, a tapered pipe is fixed inside the drain outlet, the bottom end of the tapered pipe is connected to a drain pipe, and the other end of the drain pipe extends out of the box.

[0014] Preferably, the spherical protrusion has a cavity inside, and the upper part of the spherical protrusion has a plurality of air holes communicating with the cavity. An air pipe is fixed inside the air hole, and a water-permeable component is provided inside the air pipe.

[0015] Preferably, the water-permeable component is a sponge plug fixed inside the air tube.

[0016] Compared with the prior art, the present invention provides a dehydration dryer for iron powder cores, which has the following beneficial effects:

[0017] 1. A dehydration dryer for iron powder cores, comprising a bending section, wherein when the motor is started, the motor output shaft drives the main shaft and fan blades to rotate, the fan blades strike the spherical protrusion, causing the storage bag to be thrown to one side, the storage bag bends and deforms to one side at the bending section, the bending section closely squeezes the iron powder core, squeezing out the water, and when the storage bag bends, its volume decreases, so the iron powder core is pushed and moved. Due to the setting of the bending section, the movement of the iron powder core is hindered, thereby squeezing the iron powder core, and when the fan blades move away from the spherical protrusion, the storage bag will be thrown to the other side due to gravity. In the whole process, not only is the iron powder core in the storage bag shaken, but the iron powder core is also squeezed by the bending section, thereby improving the dehydration efficiency.

[0018] 2. A dehydration dryer for iron powder cores, wherein a baffle is provided so that when the storage bag is thrown to one side, the baffle will abut against the middle part of the storage bag, while the bottom part of the storage bag will continue to move due to inertia, thereby increasing the degree of bending deformation of the storage bag, and thus increasing the squeezing force on the iron powder core at the bending part.

[0019] 3. A dehydration dryer for iron powder cores, which, by setting up a magnetic baffle, can cause relative movement between the iron powder cores by the magnetic force of the baffle on the iron powder cores through the alternating distance between the iron powder cores in the storage bag and the baffle, thereby allowing the iron powder cores to be dried faster and more evenly.

[0020] 4. A dehydration dryer for iron powder core, wherein a spring is installed so that when the storage bag shakes back and forth, the support ring bears the force of the storage bag and presses on the collar and spring, thereby causing the spring to perform elastic movement, thus amplifying the shaking of the storage bag and improving the dehydration and drying efficiency.

[0021] 5. A dehydration dryer for iron powder cores, wherein a pressure plate is set up so that when the storage bag is bent and deformed, the bent part will clamp the edge of the pressure plate, thereby fixing the pressure plate. This prevents the iron powder cores below the pressure plate from continuing to move upward along the storage bag, and they are squeezed at the pressure plate, thereby accelerating the expulsion of moisture.

[0022] 6. A dehydration dryer for iron powder cores, wherein an air pipe is installed, and when the fan blades strike the spherical protrusions, the gas in the cavity is compressed and enters the air pipe, which is then sprayed onto the iron powder core, thereby blowing the iron powder core to make it heat evenly. When the storage bag deforms, the air pipe also agitates the iron powder core. A sponge plug can prevent the iron powder core from entering the air pipe. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example

[0035] Reference Figure 1-9 A dehydration dryer for iron powder cores includes a housing 1. Baffles 2 are provided on both inner walls of the housing 1. A common carrier plate 3 is placed between the two baffles 2. A circular hole 4 is formed on the carrier plate 3, and a storage bag for holding iron powder cores is placed inside the circular hole 4. The storage bag includes a support ring 6 and a rubber bladder 5 fixed to the bottom of the support ring 6. The support ring 6 rests on the edge of the circular hole 4. The bottom of the rubber bladder 5 has an integrally formed spherical protrusion 7. The rubber bladder 5 has a bent portion 8 with densely packed small holes. A partition plate 10 is fixed inside the housing 1, located below the baffles 2. The partition plate 10 and the carrier plate 3 together form a drying chamber 9. A motor 11 is located below the partition plate 10. The output shaft of the motor 11 is connected to a main shaft 12 passing through the partition plate 10. The top of the main shaft 12 is fixed with a component that can interact with the spherical protrusion 7. When the protrusion 7 contacts the fan blade 13, the motor 11 is started. The output shaft of the motor 11 drives the main shaft 12 and the fan blade 13 to rotate. The fan blade 13 strikes the spherical protrusion 7, causing the storage bag to be thrown to one side. The storage bag will bend and deform to one side at the bend 8. The bend 8 is close to the iron powder core and squeezes it, squeezing out the water. Moreover, when the storage bag bends, its volume will decrease, so the iron powder core will be pushed and moved. Due to the bend 8, the movement of the iron powder core is hindered, thereby squeezing the iron powder core. When the fan blade 13 moves away from the spherical protrusion 7, the storage bag will be thrown to the other side due to gravity. In the whole process, not only is the iron powder core in the storage bag shaken, but the iron powder core is also squeezed by the bend 8, thereby improving the dehydration efficiency.

[0036] Furthermore, a pair of hanging rods 14 fixed to the bottom of the carrier plate 3 are provided near the circular hole 4. The bottom ends of the two hanging rods 14 are fixed with the same arc-shaped stop bar 15. When the storage bag is thrown to one side, the stop bar 15 will abut against the middle part of the storage bag, while the bottom part of the storage bag will continue to move due to inertia, thereby increasing the degree of bending deformation of the storage bag, thus making the squeezing force on the iron powder core at the bending part 8 greater.

[0037] Furthermore, the baffle 15 is magnetic. As the distance between the iron powder core inside the storage bag and the baffle 15 changes alternately, the magnetic force of the baffle 15 on the iron powder core can cause the iron powder core to move relative to each other, thereby allowing the iron powder core to dry faster and more evenly.

[0038] Furthermore, the support ring 6 has multiple insertion holes 16 arranged in a ring array. Near the round hole 4, there are multiple limiting posts 17 arranged in a ring array and fixed to the top of the carrier plate 3 for inserting into the insertion holes 16. A collar 19 is sleeved on the limiting post 17 and abuts against the bottom surface of the support ring 6. A spring 18 is fixed on the bottom surface of the collar 19 and sleeved on the limiting post 17, with its bottom end abutting against the carrier plate 3. When the storage bag shakes back and forth, the support ring 6 bears the force of the storage bag and presses on the collar 19 and the spring 18, thereby causing the spring 18 to perform elastic movement, thereby amplifying the shaking of the storage bag and improving the dehydration and drying efficiency.

[0039] Furthermore, the storage bag contains a pressure plate 20 for pressing the iron powder core. The pressure plate 20 has densely distributed water-permeable holes. After the iron powder core is poured into the storage bag, the pressure plate 20 is simply placed inside the storage bag. The pressure plate 20 is located on the surface of the iron powder core. When the storage bag is bent and deformed, the bending part 8 will clamp the edge of the pressure plate 20, thus fixing the pressure plate 20. This prevents the iron powder core below the pressure plate 20 from continuing to move upward along the storage bag, and it will be squeezed at the pressure plate 20, thereby accelerating the squeezing out of the water.

[0040] Furthermore, the bottom inner wall of the housing 1 is provided with a positioning protrusion ring 28, the motor 11 is fixed inside the positioning protrusion ring 28, and a rubber ring 21 is fitted on the motor 11, the outer surface of which is pressed against the inner wall of the positioning protrusion ring 28. The rubber ring 21 is in contact with the motor 11, which increases the shock resistance of the motor 11.

[0041] Furthermore, hot air blowers 22 are fixed to the inner walls of both sides of the box 1 and are located inside the drying chamber 9. The top of the box 1 is covered with a cover plate 26, and an observation window 27 is provided on the cover plate 26. When the hot air blower 22 is turned on, the hot air generated by the hot air blower 22 is used to dry the moisture, and the heat loss is reduced by the cover plate 26.

[0042] Furthermore, a drain outlet 23 is provided on the partition 10, and a conical tube 24 is fixed inside the drain outlet 23. The bottom end of the conical tube 24 is connected to a drain pipe 25. The other end of the drain pipe 25 passes through the box 1. The water squeezed out from the storage bag flows into the conical tube 24 and then flows away along the drain pipe 25, thereby draining the water in time.

[0043] Furthermore, a cavity 29 is provided inside the spherical protrusion 7, and multiple air holes 30 communicating with the cavity 29 are provided on the upper part of the spherical protrusion 7. An air pipe 31 is fixed inside the air hole 30, and a water-permeable component is provided inside the air pipe 31. When the fan blade 13 strikes the spherical protrusion 7, the gas in the cavity 29 is compressed and enters the air pipe 31, and then sprays it toward the iron powder core, thereby blowing the iron powder core to make it heat evenly. When the storage bag deforms, the air pipe 31 will also agitate the iron powder core.

[0044] Furthermore, the water-permeable component is a sponge plug 32 fixed inside the air pipe 31, which can prevent iron powder core from entering the air pipe 31.

[0045] Working principle: The iron powder core is loaded into the storage bag, and the pressure plate 20 is placed inside the storage bag, with the pressure plate 20 positioned on the surface of the iron powder core. Then, the storage bag is placed into the round hole 4, and the cover plate 26 is closed. The motor 11 and the hot air blower 22 are then started. The hot air generated by the hot air blower 22 dries the moisture. The output shaft of the motor 11 drives the main shaft 12 and the fan blades 13 to rotate. The fan blades 13 strike the spherical protrusion 7, causing the storage bag to be thrown to one side. The storage bag bends and deforms to one side at the bending part 8, and the bending part 8 closely presses against the iron powder core to form... The water is squeezed out, and when the storage bag bends, its volume decreases, so the iron powder core is pushed and moved. Due to the setting of the bending part 8, the movement of the iron powder core is hindered, thereby squeezing the iron powder core. When the fan blade 13 moves away from the spherical protrusion 7, the storage bag will swing to the other side due to gravity. In the whole process, not only is the iron powder core in the storage bag shaken, but the iron powder core is also squeezed by the bending part 8. The water squeezed out from the storage bag flows into the conical tube 24 and then flows away along the drain pipe 25.

[0046] When the storage bag is thrown to one side, the stop bar 15 will abut against the middle part of the storage bag, while the bottom part of the storage bag will continue to move due to inertia, thereby increasing the degree of bending deformation of the storage bag, and thus making the squeezing force on the iron powder core at the bending part 8 greater.

[0047] Because the distance between the iron powder core inside the storage bag and the baffle 15 changes alternately, the magnetic force of the baffle 15 on the iron powder core can cause the iron powder core to move relative to each other, so that the iron powder core can be dried faster and more evenly.

[0048] When the storage bag swings back and forth, the support ring 6 bears the force of the storage bag and presses on the collar 19 and the spring 18, thereby causing the spring 18 to make elastic movements, which intensifies the swinging of the storage bag.

[0049] When the storage bag is bent and deformed, the bending part 8 will clamp the edge of the pressure plate 20, thus fixing the pressure plate 20. This prevents the iron powder core below the pressure plate 20 from continuing to move upward along the storage bag, so that it can be squeezed at the pressure plate 20, thereby accelerating the squeezing out of the water.

[0050] When the fan blade 13 strikes the spherical protrusion 7, the gas in the cavity 29 is compressed and enters the air pipe 31, and then sprays it onto the iron powder core, thereby blowing the iron powder core to make it heat evenly. When the storage bag deforms, the air pipe 31 will also stir the iron powder core.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
