Description

Technical Field

[0001] This invention relates to the field of aluminum powder preparation equipment technology, specifically to an atomizing device for aluminum powder preparation. Background Technology

[0002] In the field of metal powder processing, the preparation of aluminum powder is one of the important process steps. In the prior art, patent CN117961071B discloses an atomizer for metal powder production. This atomizer achieves the functions of atomizing metal powder and cleaning the filter plate through a complex mechanical structure. It drives a turntable to rotate via a rotary driver, which in turn drives the feed pipe and an annular water tank to rotate. Simultaneously, it uses nozzles to atomize the molten metal and a metal powder filtration and cleaning assembly to clean the filter plate, thus solving the problem of metal powder clogging the filter pores.

[0003] However, this existing technology has the following shortcomings: The filter plate cleaning effect is limited. Although water can be sprayed from a nozzle for cleaning, the fixed filter plate restricts the spray angle and range, making it difficult to thoroughly clean the filter plate. This results in some metal powder remaining on the filter plate, affecting subsequent atomization effects and equipment lifespan. The metal powder collection efficiency is low. In existing technologies, metal powder falls directly to the bottom of the atomization chamber after atomization, mixing with water. Subsequent complex separation and drying processes are required to obtain pure metal powder, increasing production and time costs.

[0004] In view of the problems existing in the prior art, the present invention proposes an improved atomizing device for aluminum powder preparation, which aims to solve the problems of limited cleaning effect of filter plate and low metal powder collection efficiency in the prior art, so as to improve the efficiency and quality of aluminum powder preparation and reduce production costs.

A filter screen is fixedly installed on one side wall of the L-shaped plate, the filter screen filters the metal powder, and the metal powder is retained on the L-shaped plate and the filter screen. After partial rotation of the L-shaped plate, the filter screen is rotated as a whole, pushing the metal powder into the collecting hopper.

[0009] Optionally, the spraying component further includes a first water tank, a second water tank, and a bidirectional gear pump. The first water tank is fixedly installed on the inner bottom wall of the atomizing box, and the second water tank is fixedly installed on the lower outer wall of the atomizing box.

[0011] Optionally, the connecting bucket is funnel-shaped, and is fitted onto the middle outer wall of the guide tube with both fixedly installed. The upper edge of the connecting bucket is fixedly connected to the inner wall of the atomizing box. The wide-angle nozzle is located inside the connecting bucket, and a one-way valve is fixedly installed on the upper wall of the guide tube. The guide tube communicates with the inside of the connecting bucket through the one-way valve.

[0012] Optionally, a driving component is fixedly installed on the lower outer wall of the atomizing box. The driving component is connected to two L-shaped plates respectively, and the driving component synchronously drives the two L-shaped plates to rotate locally.

[0013] Optionally, the driving component includes a servo electric cylinder, which is fixedly installed on the lower outer wall of the atomizing box. The output shaft of the servo electric cylinder is connected to two L-shaped plates respectively, and the servo electric cylinder synchronously drives the two L-shaped plates to rotate locally.

[0014] Optionally, the driving component further includes a guide plate, guide rails, a T-shaped frame, and two racks. A first gear is fixedly installed at the central shaft end of the L-shaped plate. Two parallel guide rails are fixedly installed on the lower outer wall of the atomizing box.

The guide plate is fixedly installed on the output shaft end of the servo electric cylinder. The servo electric cylinder drives the guide plate to move laterally. During the lateral movement, the guide plate pushes the T-shaped frame to move up and down reciprocally through the protrusion.

[0017] Optionally, a cover plate is detachably installed on the lower outer wall of the atomizing box, and the cover plate covers the driving component.

[0018] (III) Beneficial Effects

[0019] This invention provides an atomizing device for aluminum powder preparation, which has the following beneficial effects:

[0020] 1. This invention achieves comprehensive and efficient cleaning of the filter screen by incorporating a flip-up L-shaped plate and filter screen, combined with the backwashing function of a wide-angle nozzle. During the cleaning process, the high-pressure water jet from the wide-angle nozzle backwashes the filter screen's pores, effectively removing aluminum powder stuck in the pores and preventing clogging. Subsequently, a servo electric cylinder drives the L-shaped plate to flip, allowing the aluminum powder on the filter screen to fall smoothly into the collection hopper. This design not only improves the cleaning effect of the filter screen but also avoids the problems of reduced atomization effect and shortened equipment lifespan caused by filter screen clogging, significantly improving the equipment's operating efficiency and stability.

[0021] 2. The atomization device of this invention is designed with full consideration of the collection efficiency of metal powder. By setting collection hoppers on both sides of the lower end of the atomization box and enabling the L-shaped plate and filter screen to flip, direct collection of metal powder is achieved. During the atomization process, the metal powder is filtered and retained on the L-shaped plate and filter screen. When it is necessary to collect the metal powder, the L-shaped plate is simply flipped by a servo electric cylinder, allowing the metal powder to fall directly into the collection hopper without the need for complex separation and drying processes. This efficient collection method not only improves the collection efficiency of metal powder but also reduces production and time costs, thereby improving the overall economic benefits of aluminum powder preparation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments.

[0034] Please see Figures 1 to 8 The present invention provides a technical solution: an atomizing device for aluminum powder preparation, comprising an atomizing box 1, two L-shaped plates 5, two collecting hoppers 4, and a spraying component. The two collecting hoppers 4 are respectively fixedly installed on the lower two side walls of the atomizing box 1, and the two L-shaped plates 5 are symmetrically rotated and installed on the middle two side walls of the atomizing box 1.

[0035] A feed pipe 2 is fixedly installed on the top wall of the atomizing box 1, and the two are connected. The feed pipe 2 introduces molten metal into the atomizing box 1. The spraying components include an annular nozzle 7 and a wide-angle nozzle 10. The annular nozzle 7 is fixedly installed on the inner top wall of the atomizing box 1 (specifically, a fixing block 6 is fixedly connected to the inner top wall of the atomizing box 1, and the annular nozzle 7 is fixedly installed on the fixing block 6). The annular nozzle 7 sprays water to atomize the molten metal flowing out of the feed pipe 2, and the molten metal is atomized into powder. The wide-angle nozzle 10 is fixedly installed in the lower inner part of the atomizing box 1, and the wide-angle nozzle 10 is located below the filter screen 8.

[0036] A filter screen 8 is fixedly installed on one side wall of the L-shaped plate 5. The filter screen 8 filters metal powder, which is then retained on the L-shaped plate 5 and the filter screen 8. After the L-shaped plate 5 is partially rotated, it causes the filter screen 8 to flip over, pushing the metal powder into the collection hopper 4.

[0037] The atomizing box 1 is the core working chamber, providing a sealed space to support the operation of various components. The collection hopper 4 is used to receive and collect the finished aluminum powder. The feed pipe 2 is responsible for introducing the molten metal into the box. In the spraying components, the annular nozzle 7 mainly consists of an annular tube and multiple nozzles. Each nozzle is fixedly installed on the annular tube in a circular array, and the annular tube is connected to each nozzle. The annular nozzle 7 atomizes the molten metal flowing out of the feed pipe 2 by spraying water. The nozzles on the annular nozzle 7 include, but are not limited to, wide-angle atomizing nozzles. The wide-angle nozzle 10 is located in the lower part of the atomizing box 1, below the filter screen 8, to assist in cleaning the filter screen 8. The L-shaped plate 5 is symmetrically rotated and installed in the middle of the atomizing box 1. The filter screen 8 fixed to its wall can filter and retain the aluminum powder. When the L-shaped plate 5 rotates partially, it causes the filter screen 8 to flip, pushing the aluminum powder into the collection hopper 4.

[0038] Specifically, the spraying components also include a first water tank 11, a second water tank 14, and a bidirectional gear pump 15. The first water tank 11 is fixedly installed on the inner bottom wall of the atomizing box 1, and the second water tank 14 is fixedly installed on the lower outer wall of the atomizing box 1. One medium flow end of the bidirectional gear pump 15 is connected to the first water tank 11, and the other medium flow end of the bidirectional gear pump 15 is connected to the second water tank 14. The second water tank 14 is connected to the annular nozzle 7, and the first water tank 11 is connected to the wide-angle nozzle 10.

[0039] In the spray system, the first water tank 11 is fixed to the bottom wall of the atomizing box 1, storing cooling water and supplying water to the wide-angle nozzle 10; the second water tank 14 is installed on the lower outer side of the atomizing box 1, storing water and communicating with the annular nozzle 7. The bidirectional gear pump 15 is the power core, with its two ends connected to the first water tank 11 and the second water tank 14 respectively, driving the cooling water to circulate and supplying high-pressure water to the annular nozzle 7 for metal molten atomization, while simultaneously supplying pressure to the wide-angle nozzle 10 to clean the filter screen 8, ensuring the stable operation of the spray system.

[0040] During the atomization stage, the bidirectional gear pump 15 starts and drives the medium flow. Its medium end, connected to the first water tank 11, draws cooling water from the tank, pressurizes it, and delivers it to the second water tank 14. The high-pressure water stored in the second water tank 14 flows along the pipeline to the annular nozzle 7, providing a stable water source for the atomization of the molten metal. During the cleaning stage, the bidirectional gear pump 15 reverses its rotation. Water drawn from the second water tank 14 is pressurized and sent to the first water tank 11, which then supplies the wide-angle nozzle 10, forming a reverse flushing water flow to backwash the filter screen 8, preventing it from being clogged by aluminum powder. The various components work together to achieve the switching of the spraying function.

[0041] More specifically, the spraying component also includes a connecting pipe 13, a guide pipe, and a connecting hopper 9. One end of the connecting pipe 13 is fixedly installed and connected to the annular nozzle 7, and the other end of the connecting pipe 13 is fixedly installed and connected to the second water tank 14. The lower end of the guide pipe is fixedly installed and connected to the first water tank 11, and the upper end of the guide pipe is fixedly installed and connected to the wide-angle nozzle 10.

[0042] The connecting pipe 13 is a key water supply channel between the second water tank 14 and the annular nozzle 7, with both ends fixedly connected to both to ensure a stable supply of high-pressure cooling water to the annular nozzle 7 to meet atomization requirements. The guide pipe is responsible for supplying water between the first water tank 11 and the wide-angle nozzle 10, with its lower end connected to the first water tank 11 and its upper end connected to the wide-angle nozzle 10, ensuring accurate delivery of rinsing water. The connecting hopper 9 can gather water flow, helping to improve water circulation efficiency and jointly ensuring the stable operation of the spray system. The water flow gathers in the connecting hopper 9, realizing water recycling.

[0043] More specifically, the connecting bucket 9 is funnel-shaped and is fitted onto the outer wall of the middle part of the guide tube, with both fixedly installed. The upper edge of the connecting bucket 9 is fixedly connected to the inner wall of the atomizing box 1. The wide-angle nozzle 10 is located inside the connecting bucket 9, and a one-way valve 12 is fixedly installed on the upper wall of the guide tube, through which the guide tube communicates with the interior of the connecting bucket 9.

[0044] The funnel-shaped connecting hopper 9 collects the atomized water flow and fixes the guide pipe. The wide-angle nozzle 10 is placed inside the connecting hopper 9, so that the rinsing water is concentrated on the filter screen 8. The one-way valve 12 at the top of the guide pipe connects it to the connecting hopper 9, allowing water from the connecting hopper 9 to flow into the guide pipe in only one direction. The water then flows into the first water tank 11 through the guide pipe, preventing backflow and ensuring stable water circulation.

[0045] Specifically, a driving component is fixedly installed on the lower outer wall of the atomizing box 1. The driving component is connected to two L-shaped plates 5 respectively, and the driving component synchronously drives the two L-shaped plates 5 to rotate locally.

[0046] The atomizing box 1 provides a mounting base for the drive component, which is fixed to its lower outer wall. The core function of the drive component is to establish a transmission connection with the two L-shaped plates 5, and drive them to rotate locally through synchronous driving force, thereby causing the filter screen 8 on the L-shaped plates 5 to flip, realizing the efficient delivery of metal powder to the collection hopper 4, and ensuring the continuity of the filtration and collection process.

[0047] More specifically, the driving component includes a servo electric cylinder 18, which is fixedly installed on the lower outer wall of the atomizing box 1. The output shaft of the servo electric cylinder 18 is connected to two L-shaped plates 5 respectively, and the servo electric cylinder 18 synchronously drives the two L-shaped plates 5 to rotate locally.

[0048] The atomizing box 1 provides a stable mounting platform for the servo electric cylinder 18, fixing it to its lower outer wall. The servo electric cylinder 18 is the power core, and its output shaft is connected to two L-shaped plates 5. By precisely outputting synchronous driving force, it drives the two plates to rotate locally, thereby realizing the flipping of the filter screen 8 and the unloading of powder, ensuring efficient and continuous operation.

[0049] More specifically, the drive component also includes a guide plate 19, guide rails 22, a T-shaped frame 21, and two racks 17. A first gear 16 is fixedly installed at the central shaft end of the L-shaped plate 5. Two parallel guide rails 22 are fixedly installed on the lower outer wall of the atomizing box 1. The T-shaped frame 21 is longitudinally slidably installed on the two guide rails 22. The two racks 17 are respectively fixedly installed at both ends of the T-shaped frame 21, and the racks 17 mesh with the first gear 16. A transverse sliding groove 20 is provided on the lower outer wall of the atomizing box 1. The guide plate 19 is laterally slidably installed with the atomizing box 1 through the sliding groove 20. A guide groove is provided on the guide plate 19. A protrusion 23 is fixedly installed on the T-shaped frame 21, and the protrusion 23 is slidably connected to the guide plate 19 through the guide groove.

[0050] The guide groove is composed of a first inclined groove 24, a second inclined groove 25, and a third inclined groove 26 that are interconnected. The guide plate 19 is fixedly installed at the output shaft end of the servo electric cylinder 18. The servo electric cylinder 18 drives the guide plate 19 to move laterally. During the lateral movement, the guide plate 19 pushes the T-shaped frame 21 to move up and down reciprocally through the protrusion 23.

[0051] The atomizing box 1 provides an installation reference for the drive system. Two parallel guide rails 22 are fixed to its lower outer wall, and a transverse sliding groove 20 is also provided. The guide rails 22 guide the T-shaped frame 21, allowing it to slide stably longitudinally. The racks 17 fixed at both ends of the T-shaped frame 21 precisely mesh with the first gear 16 at the end of the central shaft of the L-shaped plate 5, forming the core of the transmission. The guide plate 19 slides laterally with the atomizing box 1 through the sliding groove 20. Its guide groove engages with the protrusion 23 of the T-shaped frame 21, converting the lateral movement into longitudinal driving force, ultimately driving the racks 17 to drive the first gear 16, achieving synchronous rotation of the two L-shaped plates 5, ensuring the filter screen 8 flips and powder is unloaded.

[0052] The servo electric cylinder 18 is the power source, with its output shaft end fixed to the guide plate 19 and driving it to move laterally. The guide groove on the guide plate 19 is composed of a first inclined groove 24, a second inclined groove 25, and a third inclined groove 26 that are connected, and the protrusion 23 of the T-shaped frame 21 is embedded in the groove. During movement, the first inclined groove 24 and the third inclined groove 26 convert the lateral force into a longitudinal force, the second inclined groove 25 temporarily stabilizes the T-shaped frame 21, and finally pushes the T-shaped frame 21 to reciprocate up and down, providing stable power for the subsequent driving of the L-shaped plate 5.

[0053] After the servo electric cylinder 18 is started, its output shaft pushes the guide plate 19 to slide laterally along the slide groove 20 at the bottom of the atomizing box 1. The guide groove of the guide plate 19 forms a sliding engagement with the protrusion 23 of the T-shaped frame 21, converting the lateral force into a longitudinal driving force, which drives the T-shaped frame 21 to slide stably longitudinally along the parallel guide rail 22 on the atomizing box 1. The racks 17 at both ends of the T-shaped frame 21 move synchronously and mesh with the first gear 16 at the end of the central shaft of the L-shaped plate 5, ultimately driving the two first gears 16 to rotate synchronously, driving the L-shaped plate 5 to complete a partial rotation action, realizing the flipping function of the filter screen 8.

[0054] More specifically, a cover plate 3 is detachably installed on the lower outer wall of the atomizing box 1, and the cover plate 3 covers the driving component.

[0055] The atomizing box 1 provides a mounting carrier for the cover plate 3, which is detachably mounted on its lower outer wall to cover the drive components. This not only blocks dust and debris to protect the drive components but also facilitates disassembly for maintenance and repair, ensuring the stable operation of the drive system.

[0056] When using, start-up preparation: check that the atomizing box 1 is sealed properly, the cover plate 3 covers the drive components, and the filter screen 8 is installed securely; add water to the first water tank 11 and the second water tank 14 to the specified liquid level, and ensure that the bidirectional gear pump 15 is properly connected to the pipeline.

[0057] Atomization production: The molten metal is introduced into the atomization box 1 through the feed pipe 2. The bidirectional gear pump 15 drives the cooling water from the second water tank 14 through the connecting pipe 13 to the annular nozzle 7. The high-pressure water atomizes the molten metal into powder. The powder is intercepted by the filter screen 8 on the L-shaped plate 5. The water flows back to the first water tank 11 through the connecting hopper 9 and the one-way valve 12.

[0058] Cleaning and Collection: Servo electric cylinder 18 pushes guide plate 19 to slide along slide groove 20, protrusion 23 drives T-shaped frame 21 to rise and fall along guide rail 22 along guide groove (including first inclined groove 24, etc.), rack 17 meshes with first gear 16 to make L-shaped plate 5 flip, and powder falls into collection hopper 4. Bidirectional gear pump 15 operates in reverse, causing wide-angle nozzle 10 to spray water jet, which reverses the flow to rinse filter screen 8 and prevent filter screen 8 mesh from clogging.

[0059] Reset: Servo electric cylinder 18 retracts to return all components to their positions, and the equipment is ready for the next round of operation.
