Description

Technical Field

[0001] This invention relates to the field of magnetic powder production technology, specifically to a drying device for magnetic powder. Background Technology

[0002] In the preparation and processing of magnetic powders, cleaning is often required to improve the cleanliness of the powder surface and ensure the consistency and controllability of the powder surface quality. Ultrasonic cleaning is a cleaning method that uses the enormous energy released by the cavitation effect of tiny bubbles generated when ultrasonic waves propagate in a medium solution to peel off contaminants. It has the advantages of high cleaning efficiency and good cleaning effect, and is widely used in cleaning powdery materials.

[0003] In most ultrasonic cleaning equipment used for cleaning powder materials, the filtration and drying process mainly relies on screens with mesh sizes smaller than the powder particle size to achieve solid-liquid separation between the material and the cleaning liquid. However, after solid-liquid separation, the moist ultrafine magnetic powder will adhere to and get stuck in the small mesh of the screen, making it difficult to remove and dry. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a drying device for magnetic powders, which solves the problems mentioned in the background.

[0005] This invention provides the following technical solution: a drying device for magnetic powder, comprising: An ultrasonic cleaning system is used to ultrasonically clean magnetic powder and adsorb and retain the magnetic powder during drainage. The material-carrying mechanism located inside the ultrasonic cleaning unit is used to transport and support the magnetic powder and to provide support for the misaligned screening mechanism. An offset screening mechanism installed at the bottom of the material collection mechanism is used to intercept magnetic powder during liquid discharge. A drying and draining mechanism installed on top of the ultrasonic cleaning unit is used for liquid discharge and air intake heating, thereby cooperating with the ultrasonic cleaning unit to dry the magnetic powder.

[0006] Preferably, the ultrasonic cleaning mechanism includes: An outer support shell is used to support the non-magnetic inner shell. An ultrasonic transducer is fixedly installed on the bottom wall inside the outer support shell to generate ultrasonic vibrations; The material-collecting mechanism includes: The inner support limiting frame located inside the outer support shell supports the inner lining misalignment mesh and the outer folding misalignment mesh, and forms a guide for the closure of the outer folding misalignment mesh; The misaligned screening mechanism includes: The inner lining misalignment mesh is fixedly connected inside the inner support limit frame to cooperate with the outward misalignment mesh to intercept magnetic powder; Two outwardly folded misaligned nets are rotatably connected inside the inner support limiting frame.

Both the inner lining misaligned net and the outwardly folded misaligned net have mesh holes on their surfaces. The inner diameter of the mesh holes is larger than the outer diameter of the non-magnetic material. The mesh holes on the surface of the inner lining misaligned net are misaligned with the mesh holes on the surface of the outwardly folded misaligned net. The misaligned mesh holes form a sieve with a diameter smaller than the outer diameter of the non-magnetic material. This allows the non-magnetic material to be intercepted and filtered when the outwardly folded misaligned net and the inner lining misaligned net are combined. When the outwardly folded misaligned net and the inner lining misaligned net are separated, it is convenient to clean the non-magnetic material stuck in the sieve holes. The drying and draining mechanism includes: An air inlet guide shell is fixedly connected to the surface of the outer support shell to allow air to enter during drying; A drainage guide shell is fixedly connected to the surface of the outer support shell to drain liquid and vent air, and to ensure that the non-magnetic material isolating the inner shell from leakage under normal conditions.

[0007] Preferably, the ultrasonic cleaning mechanism further includes: A non-magnetic material isolating inner shell is fixedly connected inside the outer support shell, and the surface of the non-magnetic material isolating inner shell is fixedly connected to the inner wall of the air inlet guide shell and the inner wall of the drainage guide shell, and the bottom of the non-magnetic material isolating inner shell is fixedly connected to the ultrasonic transducer to isolate liquids and materials. A bottom-attracting electromagnet is fixedly installed at the bottom of the non-magnetic inner shell to attract and intercept falling magnetic powder.

[0010] Preferably, the material-collecting mechanism further includes: The lifting feet are integrated into the lower surface of the inner support limit frame to lift the material rack; The fixed insertion ear is integrally set on the lower surface of the inner support limiting frame to cooperate with the movable insertion ear to limit the insertion pin.

[0011] Preferably, the staggered screening mechanism further includes: The movable insertion ear is integrally set on the surface of the outwardly folded misaligned mesh to cooperate with the fixed insertion ear sleeve insertion pin; The reinforcing ribs are integrally installed on the outer edge of the outward-turned misalignment net to reinforce the outward-turned misalignment net.

[0012] Preferably, the staggered screening mechanism further includes: A movable pin is inserted between the fixed and movable plug ears to position the closed outward-facing misaligned mesh. A non-slip sleeve is fixedly fitted onto the surface of the pin to prevent the pin from slipping.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This magnetic powder drying equipment, through its ultrasonic cleaning mechanism, material-collecting mechanism, staggered sieving mechanism, and drying and draining mechanism, allows the magnetic powder to be fed into the ultrasonic cleaning mechanism for cleaning during use. After cleaning, the ultrasonic cleaning mechanism, in conjunction with the drying and draining mechanism, directly dries the powder. After the material is discharged from the staggered sieving mechanism, its unfolding function expands the sieve openings, thereby ensuring that the magnetic powder is dried properly and reducing material jamming in the sieving mechanism.

[0016] This magnetic powder drying equipment, through its outer support shell, ultrasonic transducer, non-magnetic material insulating inner shell, bottom electromagnet, top cover, electric heating drying plate, pressure relief port, and flip-top door, can use the ultrasonic transducer to generate ultrasonic vibrations in conjunction with cleaning fluid to ultrasonically clean the magnetic powder inside the non-magnetic material insulating inner shell during use. Furthermore, when the cleaning fluid is discharged, the bottom electromagnet can adsorb and intercept any leaked magnetic powder inside the non-magnetic material insulating inner shell.

[0017] This magnetic powder drying equipment, through its internal support limit frame, material rack, positioning handle, lifting feet, and fixed insertion lugs, allows magnetic powder to be directly cleaned and dried inside a non-magnetic material-isolated inner shell during use, thus facilitating the quick handling of magnetic powder.

[0018] This magnetic powder drying equipment, through the design of an inner lining misaligned mesh, an outer folded misaligned mesh, movable insertion lugs, reinforcing ribs, insertion pins, and anti-slip sleeves, enables solid-liquid separation during use by utilizing the sieve holes formed by the misaligned combination of the inner lining misaligned mesh and the outer folded misaligned mesh. This ensures the solid-liquid separation effect while also improving cleaning convenience by unfolding the inner lining misaligned mesh and the outer folded misaligned mesh.

[0019] This magnetic powder drying equipment, through the installation of an air inlet guide shell, a drainage guide shell, an air inlet fan, an electric heating wire, a heat-resistant duckbill valve, and a gas-liquid mixing pump, can discharge both cleaning liquid and hot, humid airflow through the drainage guide shell during use, and heat the incoming air through the air inlet guide shell in conjunction with the electric heating wire, thereby drying the powder with the electric heating drying plate.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-6 A drying device for magnetic powder includes: an ultrasonic cleaning mechanism, a material-collecting mechanism, a staggered sieve mechanism, and a drying and draining mechanism. The ultrasonic cleaning mechanism ultrasonically cleans the magnetic powder and adsorbs and traps it during draining. The material-collecting mechanism, located inside the ultrasonic cleaning mechanism, transports and supports the magnetic powder and provides support for the staggered sieve mechanism, which is installed at the bottom of the material-collecting mechanism to intercept the magnetic powder during draining. The drying and draining mechanism, installed at the top of the ultrasonic cleaning mechanism, discharges liquid and provides air heating, thus working in conjunction with the ultrasonic cleaning mechanism to dry the magnetic powder. Through these components, the magnetic powder is fed into the ultrasonic cleaning mechanism via the material-collecting mechanism for cleaning, and then directly dried by the ultrasonic cleaning mechanism in conjunction with the drying and draining mechanism. After discharge from the staggered sieve mechanism, its expanding function enlarges the sieve openings, ensuring proper drying of the magnetic powder and reducing material jamming in the sieve mechanism.

[0024] The ultrasonic cleaning mechanism includes: an outer support shell 101, an ultrasonic transducer 102, a non-magnetic material insulating inner shell 103, a bottom-attracting electromagnet 104, an upper flip-top 105, an electric heating drying plate 106, a pressure relief port 107, and a flip-top door 108. The outer support shell 101 provides support for the non-magnetic material insulating inner shell 103. The ultrasonic transducer 102 is fixedly installed on the inner bottom wall of the outer support shell 101 to generate ultrasonic vibrations. The non-magnetic material insulating inner shell 103... 03 is fixedly connected inside the outer support shell 101, and the surface of the non-magnetic material isolating inner shell 103 is fixedly connected to the inner wall of the air inlet guide shell 401 and the inner wall of the drain guide shell 402. The bottom of the non-magnetic material isolating inner shell 103 is fixedly connected to the ultrasonic transducer 102 to isolate liquids and materials. The bottom electromagnet 104 is fixedly installed at the bottom of the non-magnetic material isolating inner shell 103 to attract and intercept falling magnetic powder. The upper flip cover 105 is rotatably connected to the air inlet guide shell 401. The top of the upper cover 105 and the top of the drainage guide shell 402 are sealed and insulated during drying. The electric heating drying plate 106 is fixedly installed on the lower surface of the upper cover 105 to directly dry the upper surface of the magnetic powder. The pressure relief port 107 is opened through the surface of the upper cover 105. The flip door 108 rotates and closes on the outer surface of the pressure relief port 107 to cooperate with the pressure relief port 107 to relieve pressure inside the non-magnetic material isolation inner shell 103. The outer support shell 101 and the ultrasonic transducer 102 are provided. The non-magnetic material insulating inner shell 103, bottom electromagnet 104, upper flip cover 105, electric heating drying plate 106, pressure relief port 107 and flip door 108 can use ultrasonic transducer 102 to generate ultrasonic vibration in conjunction with cleaning fluid to ultrasonically clean the magnetic powder inside the non-magnetic material insulating inner shell 103. When the cleaning fluid is discharged, the bottom electromagnet 104 can adsorb and intercept the leaked small amount of magnetic powder inside the non-magnetic material insulating inner shell 103.

[0025] The material-collecting mechanism includes: an inner support limiting frame 201, a material-collecting frame 202, a positioning handle 203, a lifting foot 204, and a fixed insertion ear 205. The inner support limiting frame 201 is located inside the outer support shell 101 to support the inner lining misalignment mesh 301 and the outward misalignment mesh 302, and forms a guide for the closure of the outward misalignment mesh 302. The material-collecting frame 202 is fixedly sleeved on the surface of the inner support limiting frame 201, and the material-collecting frame 202 is located inside the non-magnetic material isolating inner shell 103 to support the material-collecting frame 202. The positioning handle 203 is integrally set on the outer surface of the material-collecting frame 202. The inner support frame 201 is integrated with the material holder 202 for positioning and limiting. The lifting foot 204 is integrated on the lower surface of the inner support frame 201 to lift the material holder 202. The fixed insertion ear 205 is integrated on the lower surface of the inner support frame 201 to cooperate with the movable insertion ear 303 to limit the insertion pin 305. Through the inner support frame 201, material holder 202, positioning grip 203, lifting foot 204 and fixed insertion ear 205, the magnetic powder can be carried directly inside the non-magnetic material isolation inner shell 103 for cleaning and drying during use, which facilitates the quick loading and unloading of magnetic powder.

[0026] The misaligned screening mechanism includes: an inner misaligned mesh 301, an outwardly folded misaligned mesh 302, a movable insertion lug 303, reinforcing ribs 304, a insertion pin 305, and an anti-slip sleeve 306. The inner misaligned mesh 301 is fixedly connected inside the inner support limiting frame 201 to cooperate with the outwardly folded misaligned mesh 302 in intercepting magnetic powder. The outwardly folded misaligned mesh 302 is rotatably connected inside the inner support limiting frame 201, and there are two outwardly folded misaligned meshes 302, which are relatively distributed. Both the inner lining misalignment mesh 301 and the outer lining misalignment mesh 302 are made of non-magnetic materials. Both surfaces of the inner lining misalignment mesh 301 and the outer lining misalignment mesh 302 have mesh openings, with the inner diameter of the mesh openings larger than the outer diameter of the non-magnetic material. The mesh openings on the surface of the inner lining misalignment mesh 301 and the outer lining misalignment mesh 302 are misaligned, forming a sieve with a aperture smaller than the outer diameter of the non-magnetic material. This allows for the interception and filtering of the non-magnetic material when the outer lining misalignment mesh 302 and the inner lining misalignment mesh 301 are combined. In the outer lining misalignment mesh 302... 2. When separated from the inner lining misaligned mesh 301, it facilitates the cleaning of non-magnetic material stuck in the screen holes. The movable insertion ear 303 is integrally set on the surface of the outward-folded misaligned mesh 302 to cooperate with the fixed insertion ear 205 to connect with the insertion pin 305. The reinforcing rib 304 is integrally set on the outer edge of the outward-folded misaligned mesh 302 to reinforce the outward-folded misaligned mesh 302. The insertion pin 305 is movably inserted between the fixed insertion ear 205 and the movable insertion ear 303 to position the closed outward-folded misaligned mesh 302. The anti-slip sleeve 306 is fixed. The fixed sleeve is attached to the surface of the insertion pin 305 to prevent the insertion pin 305 from slipping. Through the set inner lining misaligned mesh 301, outer folded misaligned mesh 302, movable insertion ear 303, reinforcing side rib 304, insertion pin 305 and anti-slip sleeve 306, solid-liquid separation can be performed by using the sieve holes formed by the misaligned combination of inner lining misaligned mesh 301 and outer folded misaligned mesh 302 during use. While ensuring the solid-liquid separation effect, the unfolding of inner lining misaligned mesh 301 and outer folded misaligned mesh 302 can also improve the convenience of cleaning during cleaning.

[0027] The drying and draining mechanism includes: an air inlet guide shell 401, a drain guide shell 402, an air intake fan 403, a heating wire 404, a heat-resistant duckbill valve 405, and a gas-liquid mixing pump 406. The air inlet guide shell 401 is fixedly connected to the surface of the outer support shell 101 to allow air intake during drying. The drain guide shell 402 is fixedly connected to the surface of the outer support shell 101 to allow liquid and air exhaust, and to ensure that the non-magnetic material isolating the inner shell 103 will not leak liquid under normal conditions. The air intake fan 403 is fixedly installed on the outer surface of the air inlet guide shell 401 to pump air into the air inlet guide shell 401. The heating wire 404 is fixedly installed inside the air inlet guide shell 401. The heat-resistant duckbill valve 405 is fixedly installed inside the air inlet guide shell 401 to prevent liquid backflow and ensure airflow. The gas-liquid mixing pump 406 is fixedly installed inside the drain guide shell 402 for liquid and air extraction. Through the air inlet guide shell 401, drain guide shell 402, air inlet fan 403, heating wire 404, heat-resistant duckbill valve 405 and gas-liquid mixing pump 406, the cleaning liquid and hot and humid airflow can be discharged through the drain guide shell 402 during use, and the air inlet guide shell 401 and heating wire 404 can heat the incoming air, thereby working with the electric heating drying plate 106 for drying.

[0028] Working principle: During cleaning, the material holder 202 containing magnetic powder is placed inside the non-magnetic material isolation inner shell 103. Then, cleaning fluid is injected into the non-magnetic material isolation inner shell 103. Then, the bottom-attracting electromagnet 104 is activated. The bottom-attracting electromagnet 104 generates ultrasonic vibration, which is then transmitted to the cleaning fluid through the non-magnetic material isolation inner shell 103, thereby ultrasonically cleaning the magnetic powder submerged in the cleaning fluid. During drying, close the top cover 105 and energize the ultrasonic transducer 102. Start the gas-liquid mixing pump 406 to pump the liquid, allowing the cleaning liquid to be discharged through the drainage channel between the drainage guide shell 402 and the non-magnetic material insulating inner shell 103 and outer support shell 101. At the same time, the ultrasonic transducer 102 generates magnetic force after being energized, thereby adsorbing the small amount of magnetic powder that leaks out of the inner lining misalignment mesh 301 and the outward misalignment mesh 302 into the inside of the non-magnetic material insulating inner shell 103, preventing it from being discharged with the cleaning liquid. After the cleaning liquid is discharged, continue to start the gas-liquid mixing pump 406 and energize the electric heating drying plate 106 and the heating wire 404. Electricity is used to turn on the inlet fan 403. The inlet fan 403 continuously guides the external airflow through the air intake channel between the inlet guide shell 401 and the non-magnetic material isolation inner shell 103 and the outer support shell 101 into the non-magnetic material isolation inner shell 103. At the same time, the airflow is heated into hot airflow by the heating wire 404 when it passes through the inlet guide shell 401. The hot airflow flows through the bottom of the outwardly misaligned mesh 302 and heats the bottom of the magnetic powder. Meanwhile, the electric heating drying plate 106 continuously bakes the magnetic powder above it. The water vapor generated during baking is continuously drawn out by the gas-liquid mixing pump 406 along the drainage guide shell 402, thereby gradually drying the magnetic powder. When discharging the magnetic powder, simply lift the material holder 202 out of the non-magnetic material insulating inner shell 103 to carry away the magnetic powder. After pouring the magnetic powder into the designated container, a small amount of magnetic powder will be stuck inside the inner lining misalignment mesh 301 and the outer misalignment mesh 302. At this time, pull out the insertion pin 305 to unfold the outer misalignment mesh 302, thereby clearing the larger mesh openings of the inner lining misalignment mesh 301 and the outer misalignment mesh 302. At this time, the inner diameter of these mesh openings is relatively large, and the magnetic powder has been dried, so it can be easily brushed and cleaned.
